Petur Runolfsson 5e93f39f64 re PR libstdc++/12790 (basic_filebuf doesn't handle stateful encodings) ... 2003-11-03 Petur Runolfsson <peturr02@ru.is> PR libstdc++/12790 * include/bits/fstream.tcc: Delete _M_last_overflowed. (basic_filebuf::basic_filebuf): Initialize _M_state_last. (basic_filebuf::open, basic_filebuf::close): Assign _M_state_beg to _M_state_cur and _M_state_last. (basic_filebuf::close): Call _M_terminate_output to handle unshift and flushing. (basic_filebuf::underflow): Assign _M_state_last, throw exception instead of calling abort when codecvt::max_length() is bad. (basic_filebuf::seekoff): Use _M_state_last when calling codecvt::length(), pass correct state to _M_seek. (basic_filebuf::seekpos): Pass __pos.state() to _M_seek. (basic_filebuf::_M_seek): Add __state_type parameter, set _M_state_cur correctly, store the resulting state in the return value and use _M_terminate_output to handle flushing and unshift. (basic_filebuf::_M_terminate_output): Flush contents of output buffer, if any, then call codecvt::unshift as needed and output the result. (basic_filebuf::sync): Move here, don't modify _M_writing or _M_reading. * include/std/std_fstream.h (basic_filebuf::_M_state_last): Declare it. (basic_filebuf::_M_last_overflowed): Delete. (basic_filebuf::_M_seek): Add __state_type parameter. (basic_filebuf::sync): Declare only. (basic_filebuf::_M_output_unshift): Delete. (basic_filebuf::_M_terminate_output): Declare it. * testsuite/testsuite_character.h: Define character class and state class plus char_traits and codecvt specializations for same for testing support for stateful encodings. * testsuite/27_io/basic_filebuf/close/12790-1.cc, * testsuite/27_io/basic_filebuf/close/char/12790-1.cc, * testsuite/27_io/basic_filebuf/close/char/12790-2.cc, * testsuite/27_io/basic_filebuf/close/char/12790-3.cc, * testsuite/27_io/basic_filebuf/close/char/12790-4.cc, * testsuite/27_io/basic_filebuf/close/wchar_t/12790-1.cc, * testsuite/27_io/basic_filebuf/close/wchar_t/12790-2.cc, * testsuite/27_io/basic_filebuf/close/wchar_t/12790-3.cc, * testsuite/27_io/basic_filebuf/close/wchar_t/12790-4.cc, * testsuite/27_io/basic_filebuf/open/12790-1.cc, * testsuite/27_io/basic_filebuf/seekoff/12790-1.cc, * testsuite/27_io/basic_filebuf/seekoff/12790-2.cc, * testsuite/27_io/basic_filebuf/seekoff/12790-3.cc, * testsuite/27_io/basic_filebuf/seekoff/12790-4.cc, * testsuite/27_io/basic_filebuf/seekoff/char/12790-1.cc, * testsuite/27_io/basic_filebuf/seekoff/char/12790-2.cc, * testsuite/27_io/basic_filebuf/seekoff/char/12790-3.cc, * testsuite/27_io/basic_filebuf/seekoff/char/12790-4.cc, * testsuite/27_io/basic_filebuf/seekoff/wchar_t/12790-1.cc, * testsuite/27_io/basic_filebuf/seekoff/wchar_t/12790-2.cc, * testsuite/27_io/basic_filebuf/seekoff/wchar_t/12790-3.cc, * testsuite/27_io/basic_filebuf/seekoff/wchar_t/12790-4.cc, * testsuite/27_io/basic_filebuf/seekoff/wchar_t/3.cc, * testsuite/27_io/basic_filebuf/seekpos/12790-1.cc, * testsuite/27_io/basic_filebuf/seekpos/12790-2.cc, * testsuite/27_io/basic_filebuf/seekpos/12790-3.cc, * testsuite/27_io/basic_filebuf/seekpos/char/12790-1.cc, * testsuite/27_io/basic_filebuf/seekpos/char/12790-2.cc, * testsuite/27_io/basic_filebuf/seekpos/char/12790-3.cc, * testsuite/27_io/basic_filebuf/seekpos/char/12790-4.cc, * testsuite/27_io/basic_filebuf/seekpos/wchar_t/1.cc, * testsuite/27_io/basic_filebuf/seekpos/wchar_t/12790-1.cc, * testsuite/27_io/basic_filebuf/seekpos/wchar_t/12790-2.cc, * testsuite/27_io/basic_filebuf/seekpos/wchar_t/12790-3.cc, * testsuite/27_io/basic_filebuf/seekpos/wchar_t/12790-4.cc, * testsuite/27_io/basic_filebuf/sync/char/1.cc, * testsuite/27_io/basic_filebuf/sync/wchar_t/1.cc: New tests. * testsuite/27_io/basic_filebuf/3.cc, * testsuite/27_io/basic_filebuf/seekoff/10132-2.cc, * testsuite/27_io/basic_filebuf/seekpos/10132-3.cc, * testsuite/27_io/basic_fstream/3.cc, * testsuite/27_io/basic_ifstream/3.cc, * testsuite/27_io/basic_ofstream/3.cc: Use streamoff as off_type and fpos<state_type> as pos_type. * testsuite/27_io/basic_filebuf/seekpos/char/1-io.cc, * testsuite/27_io/basic_filebuf/seekpos/char/1-out.cc: Check that sync does *not* set _M_writing to false.
