add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

const char *
Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

/* Read memory from the live target, even if currently inspecting a
traceframe. The return is the same as that of target_read. */
Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF.

return section_table_xfer_memory_partial (readbuf, writebuf,
Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF.

Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code).

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code).

res = memory_xfer_partial_1 (ops, object, readbuf, NULL, memaddr, len,
xfered_len);
Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

This patch factors out the iteration from top to bottom to a new function, raw_memory_xfer_partial, and use it for TARGET_OBJECT_RAW_MEMORY. Regression tested on x86_64-linux. gdb: 2013-11-29 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * dcache.c (dcache_read_line): Use current_target.beneath instead of &current_target. * target.c (memory_xfer_partial_1): Factor code out to ...

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

/* Read LEN bytes of target memory at address MEMADDR, placing the

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

If an error occurs, no guarantee is made about the contents of the data at
MYADDR. In particular, the caller should not depend upon partial reads
filling the buffer with good data. There is no way for the caller to know
how much good data might have been transfered anyway. Callers that can
deal with partial reads should call target_read (which will retry until
it makes no progress, and then return how much was transferred). */

Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

/* Write LEN bytes from MYADDR to target raw memory at address
Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

MEMADDR. Returns either 0 for success or TARGET_XFER_E_IO
Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code).

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target.

/* Assuming that the entire [begin, end) range of memory cannot be
read, try to read whatever subrange is possible to read.
The function returns, in RESULT, either zero or one memory block.
If there's a readable subrange at the beginning, it is completely
read and returned. Any further readable subrange will not be read.
Otherwise, if there's a readable subrange at the end, it will be
completely read and returned. Any readable subranges before it
(obviously, not starting at the beginning), will be ignored. In
other cases -- either no readable subrange, or readable subrange(s)
that is neither at the beginning, or end, nothing is returned.
The purpose of this function is to handle a read across a boundary
of accessible memory in a case when memory map is not available.
The above restrictions are fine for this case, but will give
incorrect results if the memory is 'patchy'. However, supporting
'patchy' memory would require trying to read every single byte,
and it seems unacceptable solution. Explicit memory map is
recommended for this case -- and target_read_memory_robust will
take care of reading multiple ranges then. */

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0".

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code).

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code).

Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF.

Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

constify to_detach This patch constifies the target_ops method to_detach. This is a small cleanup, but also, I think, a bug-prevention fix, since gdb already acts as if the "args" argument here was const. In particular, top.c:quit_force calls kill_or_detach via iterate_over_inferiors. kill_or_detach calls target_detach, passing the same argument each time. So, if one of these methods was not const-correct, then kill_or_detach would change its behavior in a strange way. I could not build every target I modified in this patch. I've inspected them all by hand, though. Many targets do not use the "args" parameter; a couple pass it to atoi; and a few pass it on to the to_detach method of the target beneath. The only code that required a real change was in linux-nat.c, and that only needed the introduction of a temporary variable for const-correctness. 2013-11-08 Tom Tromey <tromey@redhat.com> * aix-thread.c (aix_thread_detach): Update. * corelow.c (core_detach): Update. * darwin-nat.c (darwin_detach): Update. * dec-thread.c (dec_thread_detach): Update. * gnu-nat.c (gnu_detach): Update. * go32-nat.c (go32_detach): Update. * inf-ptrace.c (inf_ptrace_detach): Update. * inf-ttrace.c (inf_ttrace_detach): Update. * linux-fork.c (linux_fork_detach): Update. * linux-fork.h (linux_fork_detach): Update. * linux-nat.c (linux_nat_detach): Update.

Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add "this" pointers to more target APIs A subsequent pass introduces delegation helper functions to the target API. This delegation is much cleaner if the target_ops pointer is directly available at delegation time. This patch adds the "this" pointer to various to_* methods for this purpose. This updates a number of ports which I am unable to test. Please give them a look-over.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add "this" pointers to more target APIs A subsequent pass introduces delegation helper functions to the target API. This delegation is much cleaner if the target_ops pointer is directly available at delegation time. This patch adds the "this" pointer to various to_* methods for this purpose. This updates a number of ports which I am unable to test. Please give them a look-over.

target_close (struct target_ops *targ)
{
remove pop_target This patch fixes the target double-close problem (PR remote/15266), and in the process removes pop_target entire (PR remote/15256). The first issue is that pop_target calls target_close. However, it then calls unpush_target, which also calls target_close. This means targets must be able to be closed twice. Not only is this strange, but it also directly contradicts the contract of to_xclose targets. (We currently have just a single such target, and it is never pushed; but I plan to add more, and so this latent bug is triggered.) The second issue is that it seems to me that calling pop_target is often unsafe. This is what cropped up in 15256, where the remote target assumed that it could pop_target -- but there was another target higher on the stack, leading to confusion. But, it is always just as easy to call unpush_target as it is to call pop_target; and it is also safer. So, removing pop_target seemed like an improvement. Finally, this adds an assertion to target_close to ensure that no currently-pushed target can be closed. Built and regtested on x86-64 Fedora 18; both natively and using the native-gdbserver board file.

Use gdb_byte for bytes from the program being debugged. gdb_byte should be used for bytes from the program being debugged. We have many places using char or unsigned char instead all over the existing ports, and more ends up added over time due to copy/paste as new code is based on old code. I've greped the tree for "char buf[", and fixed all I found.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.
