Make fetch a builtin Thanks to Johannes Schindelin for review and fixes, and Julian Phillips for the original C translation. This changes a few small bits of behavior: branch.<name>.merge is parsed as if it were the lhs of a fetch refspec, and does not have to exactly match the actual lhs of a refspec, so long as it is a valid abbreviation for the same ref. branch.<name>.merge is no longer ignored if the remote is configured with a branches/* file. Neither behavior is useful, because there can only be one ref that gets fetched, but this is more consistant. Also, fetch prints different information to standard out.

git-fetch: avoid local fetching from alternate (again) Back in e3c6f240fd9c5bdeb33f2d47adc859f37935e2df Junio taught git-fetch to avoid copying objects when we are fetching from a repository that is already registered as an alternate object database. In such a case there is no reason to copy any objects as we can already obtain them through the alternate. However we need to ensure the objects are all reachable, so we run `git rev-list --objects $theirs --not --all` to verify this. If any object is missing or unreadable then we need to fetch/copy the objects from the remote. When a missing object is detected the git-rev-list process will exit with a non-zero exit status, making this condition quite easy to detect. Although git-fetch is currently a builtin (and so is rev-list) we cannot invoke the traverse_objects() API at this point in the transport code. The object walker within traverse_objects() calls die() as soon as it finds an object it cannot read. If that happens we want to resume the fetch process by calling do_fetch_pack(). To get around this we spawn git-rev-list into a background process to prevent a die() from killing the foreground fetch process, thus allowing the fetch process to resume into do_fetch_pack() if copying is necessary. We aren't interested in the output of rev-list (a list of SHA-1 object names that are reachable) or its errors (a "spurious" error about an object not being found as we need to copy it) so we redirect both stdout and stderr to /dev/null. We run this git-rev-list based check before any fetch as we may already have the necessary objects local from a prior fetch. If we don't then its very likely the first $theirs object listed on the command line won't exist locally and git-rev-list will die very quickly, allowing us to start the network transfer. This test even on remote URLs may save bandwidth if someone runs `git pull origin`, sees a merge conflict, resets out, then redoes the same pull just a short time later. If the remote hasn't changed between the two pulls and the local repository hasn't had git-gc run in it then there is probably no need to perform network transfer as all of the objects are local. Documentation for the new quickfetch function was suggested and written by Junio, based on his original comment in git-fetch.sh. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

chain kill signals for cleanup functions If a piece of code wanted to do some cleanup before exiting (e.g., cleaning up a lockfile or a tempfile), our usual strategy was to install a signal handler that did something like this: do_cleanup(); /* actual work */ signal(signo, SIG_DFL); /* restore previous behavior */ raise(signo); /* deliver signal, killing ourselves */ For a single handler, this works fine. However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler. This patch introduces sigchain, a tiny library for handling a stack of signal handlers. You sigchain_push each handler, and use sigchain_pop to restore whoever was before you in the stack.

fetch/pull: Add the --recurse-submodules option Until now you had to call "git submodule update" (without -N|--no-fetch option) or something like "git submodule foreach git fetch" to fetch new commits in populated submodules from their remote. This could lead to "(commits not present)" messages in the output of "git diff --submodule" (which is used by "git gui" and "gitk") after fetching or pulling new commits in the superproject and is an obstacle for implementing recursive checkout of submodules. Also "git submodule update" cannot fetch changes when disconnected, so it was very easy to forget to fetch the submodule changes before disconnecting only to discover later that they are needed. This patch adds the "--recurse-submodules" option to recursively fetch each populated submodule from the url configured in the .git/config of the submodule at the end of each "git fetch" or during "git pull" in the superproject. The submodule paths are taken from the index. The hidden option "--submodule-prefix" is added to "git fetch" to be able to print out the full paths of nested submodules.

fetch: use argv_array instead of hand-building arrays Fetch invokes itself recursively when recursing into submodules or handling "fetch --multiple". In both cases, it builds the child's command line by pushing options onto a statically-sized array. In both cases, the array is currently just big enough to handle the largest possible case. However, this technique is brittle and error-prone, so let's replace it with a dynamic argv_array. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default.

fetch: work around "transport-take-over" hack A Git-aware "connect" transport allows the "transport_take_over" to redirect generic transport requests like fetch(), push_refs() and get_refs_list() to the native Git transport handling methods. The take-over process replaces transport->data with a fake data that these method implementations understand. While this hack works OK for a single request, it breaks when the transport needs to make more than one requests. transport->data that used to hold necessary information for the specific helper to work correctly is destroyed during the take-over process. One codepath that this matters is "git fetch" in auto-follow mode; when it does not get all the tags that ought to point at the history it got (which can be determined by looking at the peeled tags in the initial advertisement) from the primary transfer, it internally makes a second request to complete the fetch. Because "take-over" hack has already destroyed the data necessary to talk to the transport helper by the time this happens, the second request cannot make a request to the helper to make another connection to fetch these additional tags. Mark such a transport as "cannot_reuse", and use a separate transport to perform the backfill fetch in order to work around this breakage. Note that this problem does not manifest itself when running t5802, because our upload-pack gives you all the necessary auto-followed tags during the primary transfer. You would need to step through "git fetch" in a debugger, stop immediately after the primary transfer finishes and writes these auto-followed tags, remove the tag references and repack/prune the repository to convince the "find-non-local-tags" procedure that the primary transfer failed to give us all the necessary tags, and then let it continue, in order to trigger the bug in the secondary transfer this patch fixes.

fetch/pull: recurse into submodules when necessary To be able to access all commits of populated submodules referenced by the superproject it is sufficient to only then let "git fetch" recurse into a submodule when the new commits fetched in the superproject record new commits for it. Having these commits present is extremely useful when using the "--submodule" option to "git diff" (which is what "git gui" and "gitk" do since 1.6.6), as all submodule commits needed for creating a descriptive output can be accessed. Also merging submodule commits (added in 1.7.3) depends on the submodule commits in question being present to work. Last but not least this enables disconnected operation when using submodules, as all commits necessary for a successful "git submodule update -N" will have been fetched automatically. So we choose this mode as the default for fetch and pull. Before a new or changed ref from upstream is updated in update_local_ref() "git rev-list <new-sha1> --not --branches --remotes" is used to determine all newly fetched commits. These are then walked and diffed against their parent(s) to see if a submodule has been changed. If that is the case, its path is stored to be fetched after the superproject fetch is completed. Using the "--recurse-submodules" or the "--no-recurse-submodules" option disables the examination of the fetched refs because the result will be ignored anyway. There is currently no infrastructure for storing deleted and new submodules in the .git directory of the superproject. That's why fetch and pull for now only fetch submodules that are already checked out and are not renamed. In t7403 the "--no-recurse-submodules" argument had to be added to "git pull" to avoid failure because of the moved upstream submodule repo.

fetch: load all default config at startup When we start the git-fetch program, we call git_config to load all config, but our callback only processes the fetch.prune option; we do not chain to git_default_config at all. This means that we may not load some core configuration which will have an effect. For instance, we do not load core.logAllRefUpdates, which impacts whether or not we create reflogs in a bare repository. Note that I said "may" above. It gets even more exciting. If we have to transfer actual objects as part of the fetch, then we call fetch_pack as part of the same process. That function loads its own config, which does chain to git_default_config, impacting global variables which are used by the rest of fetch. But if the fetch is a pure ref update (e.g., a new ref which is a copy of an old one), we skip fetch_pack entirely. So we get inconsistent results depending on whether or not we have actual objects to transfer or not! Let's just load the core config at the start of fetch, so we know we have it (we may also load it again as part of fetch_pack, but that's OK; it's designed to be idempotent). Our tests check both cases (with and without a pack). We also check similar behavior for push for good measure, but it already works as expected.

fetch: make --prune configurable Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever. Some people want to always run "git fetch --prune". To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune": - "fetch.prune" allows to enable prune for all fetch operations. - "remote.<name>.prune" allows to change the behaviour per remote. The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default. Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

git fetch: Take '-n' to mean '--no-tags' Prior to commit 8320199 (Rewrite builtin-fetch option parsing to use parse_options().), we understood '-n' as a short option to mean "don't fetch tags from the remote". This patch reinstates behaviour similar, but not identical to the pre commit 8320199 times. Back then, -n always overrode --tags, so if both --tags and -n was given on command-line, no tags were fetched regardless of argument ordering. Now we use a "last entry wins" strategy, so '-n --tags' means "fetch tags". Since it's patently absurd to say both --tags and --no-tags, this shouldn't matter in practice.

Make upload-pack recognize this special number as infinite depth. The effect is essentially the same as before, except that upload-pack is more efficient because it does not have to traverse to the bottom anymore. The chance of a user actually wanting exactly 2147483647 commits depth, not infinite, on a repository with a history that long, is probably too small to consider. The client can learn to add or subtract one commit to avoid the special treatment when that actually happens. (*) This is the largest positive number a 32-bit signed integer can contain.

fetch/pull: recurse into submodules when necessary To be able to access all commits of populated submodules referenced by the superproject it is sufficient to only then let "git fetch" recurse into a submodule when the new commits fetched in the superproject record new commits for it. Having these commits present is extremely useful when using the "--submodule" option to "git diff" (which is what "git gui" and "gitk" do since 1.6.6), as all submodule commits needed for creating a descriptive output can be accessed. Also merging submodule commits (added in 1.7.3) depends on the submodule commits in question being present to work. Last but not least this enables disconnected operation when using submodules, as all commits necessary for a successful "git submodule update -N" will have been fetched automatically. So we choose this mode as the default for fetch and pull. Before a new or changed ref from upstream is updated in update_local_ref() "git rev-list <new-sha1> --not --branches --remotes" is used to determine all newly fetched commits. These are then walked and diffed against their parent(s) to see if a submodule has been changed. If that is the case, its path is stored to be fetched after the superproject fetch is completed. Using the "--recurse-submodules" or the "--no-recurse-submodules" option disables the examination of the fetched refs because the result will be ignored anyway. There is currently no infrastructure for storing deleted and new submodules in the .git directory of the superproject. That's why fetch and pull for now only fetch submodules that are already checked out and are not renamed. In t7403 the "--no-recurse-submodules" argument had to be added to "git pull" to avoid failure because of the moved upstream submodule repo.

fetch: work around "transport-take-over" hack A Git-aware "connect" transport allows the "transport_take_over" to redirect generic transport requests like fetch(), push_refs() and get_refs_list() to the native Git transport handling methods. The take-over process replaces transport->data with a fake data that these method implementations understand. While this hack works OK for a single request, it breaks when the transport needs to make more than one requests. transport->data that used to hold necessary information for the specific helper to work correctly is destroyed during the take-over process. One codepath that this matters is "git fetch" in auto-follow mode; when it does not get all the tags that ought to point at the history it got (which can be determined by looking at the peeled tags in the initial advertisement) from the primary transfer, it internally makes a second request to complete the fetch. Because "take-over" hack has already destroyed the data necessary to talk to the transport helper by the time this happens, the second request cannot make a request to the helper to make another connection to fetch these additional tags. Mark such a transport as "cannot_reuse", and use a separate transport to perform the backfill fetch in order to work around this breakage. Note that this problem does not manifest itself when running t5802, because our upload-pack gives you all the necessary auto-followed tags during the primary transfer. You would need to step through "git fetch" in a debugger, stop immediately after the primary transfer finishes and writes these auto-followed tags, remove the tag references and repack/prune the repository to convince the "find-non-local-tags" procedure that the primary transfer failed to give us all the necessary tags, and then let it continue, in order to trigger the bug in the secondary transfer this patch fixes.

chain kill signals for cleanup functions If a piece of code wanted to do some cleanup before exiting (e.g., cleaning up a lockfile or a tempfile), our usual strategy was to install a signal handler that did something like this: do_cleanup(); /* actual work */ signal(signo, SIG_DFL); /* restore previous behavior */ raise(signo); /* deliver signal, killing ourselves */ For a single handler, this works fine. However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler.

Make fetch a builtin Thanks to Johannes Schindelin for review and fixes, and Julian Phillips for the original C translation. This changes a few small bits of behavior: branch.<name>.merge is parsed as if it were the lhs of a fetch refspec, and does not have to exactly match the actual lhs of a refspec, so long as it is a valid abbreviation for the same ref. branch.<name>.merge is no longer ignored if the remote is configured with a branches/* file. Neither behavior is useful, because there can only be one ref that gets fetched, but this is more consistant. Also, fetch prints different information to standard out.

In shell script git-fetch and prior to the above mentioned commit this was hardcoded for a url of "." to be the set of local branches. Chasing down this bug led me to the conclusion that our prior behavior with regards to branch.$name.merge was incorrect. In the shell script based git-fetch implementation we only fetched and merged a branch if it appeared both in branch.$name.merge *and* in remote.$r.fetch, where $r = branch.$name.remote. In other words in the following config file: [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = refs/heads/master:refs/remotes/origin/master [branch "master"] remote = origin merge = refs/heads/master [branch "pu"] remote = origin merge = refs/heads/pu Attempting to run `git pull` while on branch "pu" would always give the user "Already up-to-date" as git-fetch did not fetch pu and thus did not mark it for merge in .git/FETCH_HEAD. The configured merge would always be ignored and the user would be left scratching her confused head wondering why merge did not work on "pu" but worked fine on "master". If we are using the "default fetch" specification for the current branch and the current branch has a branch.$name.merge configured we now union it with the list of refs in remote.$r.fetch. This way the above configuration does what the user expects it to do, which is to fetch only "master" by default but when on "pu" to fetch both "master" and "pu". This uncovered some breakage in the test suite where old-style Cogito branches (.git/branches/$r) did not fetch the branches listed in .git/config for merging and thus did not actually merge them if the user tried to use `git pull` on that branch. Junio and I discussed it on list and felt that the union approach here makes more sense to DWIM for the end-user than silently ignoring their configured request so the test vectors for t5515 have been updated to include for-merge lines in .git/FETCH_HEAD where they have been configured for-merge in .git/config. Since we are now performing a union of the fetch specification and the merge specification and we cannot allow a branch to be listed twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to perform a double loop here over all of the branch.$name.merge lines and try to set their merge flag if we have already schedule that branch for fetching by remote.$r.fetch.

Make fetch a builtin Thanks to Johannes Schindelin for review and fixes, and Julian Phillips for the original C translation. This changes a few small bits of behavior: branch.<name>.merge is parsed as if it were the lhs of a fetch refspec, and does not have to exactly match the actual lhs of a refspec, so long as it is a valid abbreviation for the same ref. branch.<name>.merge is no longer ignored if the remote is configured with a branches/* file. Neither behavior is useful, because there can only be one ref that gets fetched, but this is more consistant. Also, fetch prints different information to standard out.

Correct handling of branch.$name.merge in builtin-fetch My prior bug fix for git-push titled "Don't configure remote "." to fetch everything to itself" actually broke t5520 as we were unable to evaluate a branch configuration of: [branch "copy"] remote = . merge = refs/heads/master as remote "." did not have a "remote...fetch" configuration entry to offer up refs/heads/master as a possible candidate available to be fetched and merged. In shell script git-fetch and prior to the above mentioned commit this was hardcoded for a url of "." to be the set of local branches. Chasing down this bug led me to the conclusion that our prior behavior with regards to branch.$name.merge was incorrect. In the shell script based git-fetch implementation we only fetched and merged a branch if it appeared both in branch.$name.merge *and* in remote.$r.fetch, where $r = branch.$name.remote. In other words in the following config file: [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = refs/heads/master:refs/remotes/origin/master [branch "master"] remote = origin merge = refs/heads/master [branch "pu"] remote = origin merge = refs/heads/pu Attempting to run `git pull` while on branch "pu" would always give the user "Already up-to-date" as git-fetch did not fetch pu and thus did not mark it for merge in .git/FETCH_HEAD. The configured merge would always be ignored and the user would be left scratching her confused head wondering why merge did not work on "pu" but worked fine on "master". If we are using the "default fetch" specification for the current branch and the current branch has a branch.$name.merge configured we now union it with the list of refs in remote.$r.fetch. This way the above configuration does what the user expects it to do, which is to fetch only "master" by default but when on "pu" to fetch both "master" and "pu". This uncovered some breakage in the test suite where old-style Cogito branches (.git/branches/$r) did not fetch the branches listed in .git/config for merging and thus did not actually merge them if the user tried to use `git pull` on that branch. Junio and I discussed it on list and felt that the union approach here makes more sense to DWIM for the end-user than silently ignoring their configured request so the test vectors for t5515 have been updated to include for-merge lines in .git/FETCH_HEAD where they have been configured for-merge in .git/config. Since we are now performing a union of the fetch specification and the merge specification and we cannot allow a branch to be listed twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to perform a double loop here over all of the branch.$name.merge lines and try to set their merge flag if we have already schedule that branch for fetching by remote.$r.fetch.

refactor "ref->merge" flag Each "struct ref" has a boolean flag that is set by the fetch code to determine whether the ref should be marked as "not-for-merge" or not when we write it out to FETCH_HEAD. It would be useful to turn this boolean into a tri-state, with the third state meaning "do not bother writing it out to FETCH_HEAD at all". That would let us add extra refs to the set of refs to be stored (e.g., to store copies of things we fetched) without impacting FETCH_HEAD. This patch turns it into an enum that covers the tri-state case, and hopefully makes the code more explicit and easier to read.

This uncovered some breakage in the test suite where old-style Cogito branches (.git/branches/$r) did not fetch the branches listed in .git/config for merging and thus did not actually merge them if the user tried to use `git pull` on that branch. Junio and I discussed it on list and felt that the union approach here makes more sense to DWIM for the end-user than silently ignoring their configured request so the test vectors for t5515 have been updated to include for-merge lines in .git/FETCH_HEAD where they have been configured for-merge in .git/config. Since we are now performing a union of the fetch specification and the merge specification and we cannot allow a branch to be listed twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to perform a double loop here over all of the branch.$name.merge lines and try to set their merge flag if we have already schedule that branch for fetching by remote.$r.fetch. If no match is found then we must add new specifications to fetch the branch but not store it as no local tracking branch has been designated. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

refactor "ref->merge" flag Each "struct ref" has a boolean flag that is set by the fetch code to determine whether the ref should be marked as "not-for-merge" or not when we write it out to FETCH_HEAD. It would be useful to turn this boolean into a tri-state, with the third state meaning "do not bother writing it out to FETCH_HEAD at all". That would let us add extra refs to the set of refs to be stored (e.g., to store copies of things we fetched) without impacting FETCH_HEAD. This patch turns it into an enum that covers the tri-state case, and hopefully makes the code more explicit and easier to read.

Make git-fetch follow tags we already have objects for sooner If autofollowing of tags is enabled, we see a new tag on the remote that we don't have, and we already have the SHA-1 object that the tag is peeled to, then we can fetch the tag while we are fetching the other objects on the first connection. This is a slight optimization for projects that have a habit of tagging a release commit after most users have already seen and downloaded that commit object through a prior fetch session. In such cases the users may still find new objects in branch heads, but the new tag will now also be part of the first pack transfer and the subsequent connection to autofollow tags is not required. Currently git.git does not benefit from this optimization as any release usually gets a new commit at the same time that it gets a new release tag, however git-gui.git and many other projects are in the habit of tagging fairly old commits. Users who did not already have the tagged commit still require opening a second connection to autofollow the tag, as we are unable to determine on the client side if $tag^{} will be sent to the client during the first transfer or not.

Some users find this confusing, because they would want to do further comparisons against the old state of the remote master, like: $ git pull origin master $ git log HEAD...origin/master In the currnet code, they are comparing against whatever commit happened to be in origin/master from the last time they did a complete "git fetch". This patch will update a ref from the RHS of a configured refspec whenever we happen to be fetching its LHS. That makes the case above work. The downside is that any users who really care about whether and when their tracking branches are updated may be surprised.

fetch: only opportunistically update references based on command line The old code processed (tags == TAGS_SET) before adding the entries used to opportunistically update references mentioned on the command line. The result was that all tags were also considered candidates for opportunistic updating. This is harmless for two reasons: (a) because it would only add entries if there is a configured refspec that covers tags *and* both --tags and another refspec appear on the command-line; (b) because any extra entries would be deleted later by the call to ref_remove_duplicates() anyway. But, to avoid extra work and extra memory usage, and to make the implementation better match the intention, change the algorithm slightly: compute the opportunistic refspecs based only on the command-line arguments, storing the results into a separate temporary list. Then add the tags (which have to come earlier in the list so that they are not de-duped in favor of an opportunistic entry). Then concatenate the temporary list onto the main list. This change will also make later changes easier. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Correct handling of branch.$name.merge in builtin-fetch My prior bug fix for git-push titled "Don't configure remote "." to fetch everything to itself" actually broke t5520 as we were unable to evaluate a branch configuration of: [branch "copy"] remote = . merge = refs/heads/master as remote "." did not have a "remote...fetch" configuration entry to offer up refs/heads/master as a possible candidate available to be fetched and merged. In shell script git-fetch and prior to the above mentioned commit this was hardcoded for a url of "." to be the set of local branches. Chasing down this bug led me to the conclusion that our prior behavior with regards to branch.$name.merge was incorrect. In the shell script based git-fetch implementation we only fetched and merged a branch if it appeared both in branch.$name.merge *and* in remote.$r.fetch, where $r = branch.$name.remote. In other words in the following config file: [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = refs/heads/master:refs/remotes/origin/master [branch "master"] remote = origin merge = refs/heads/master [branch "pu"] remote = origin merge = refs/heads/pu Attempting to run `git pull` while on branch "pu" would always give the user "Already up-to-date" as git-fetch did not fetch pu and thus did not mark it for merge in .git/FETCH_HEAD. The configured merge would always be ignored and the user would be left scratching her confused head wondering why merge did not work on "pu" but worked fine on "master". If we are using the "default fetch" specification for the current branch and the current branch has a branch.$name.merge configured we now union it with the list of refs in remote.$r.fetch. This way the above configuration does what the user expects it to do, which is to fetch only "master" by default but when on "pu" to fetch both "master" and "pu". This uncovered some breakage in the test suite where old-style Cogito branches (.git/branches/$r) did not fetch the branches listed in .git/config for merging and thus did not actually merge them if the user tried to use `git pull` on that branch. Junio and I discussed it on list and felt that the union approach here makes more sense to DWIM for the end-user than silently ignoring their configured request so the test vectors for t5515 have been updated to include for-merge lines in .git/FETCH_HEAD where they have been configured for-merge in .git/config. Since we are now performing a union of the fetch specification and the merge specification and we cannot allow a branch to be listed twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to perform a double loop here over all of the branch.$name.merge lines and try to set their merge flag if we have already schedule that branch for fetching by remote.$r.fetch. If no match is found then we must add new specifications to fetch the branch but not store it as no local tracking branch has been designated. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

builtin/fetch.c: ignore merge config when not fetching from branch's remote When 'git fetch' is supplied a single argument, it tries to match it against a configured remote and then fetch the refs specified by the named remote's fetchspec. Additionally, or alternatively, if the current branch has a merge ref configured, and if the name of the remote supplied to fetch matches the one in the branch's configuration, then git also adds the merge ref to the list of refs to update. If the argument to fetch does not specify a named remote, or if the name supplied does not match the remote configured for the current branch, then the current branch's merge configuration should not be considered. git currently mishandles the case when the argument to fetch specifies a GIT URL(i.e. not a named remote) and the current branch has a configured merge ref. In this case, fetch should ignore the branch's merge ref and attempt to fetch from the remote repository's HEAD branch. But, since fetch only checks _whether_ the current branch has a merge ref configured, and does _not_ check whether the branch's configured remote matches the command line argument (until later), it will mistakenly enter the wrong branch of an 'if' statement and will not fall back to fetch the HEAD branch. The fetch ends up doing nothing and returns with a successful zero status. Fix this by comparing the remote repository's name to the branch's remote name, in addition to whether it has a configured merge ref, sooner, so that fetch can correctly decide whether the branch's configuration is interesting or not, and fall back to fetching from the remote's HEAD branch when appropriate.

This is harmless for two reasons: (a) because it would only add entries if there is a configured refspec that covers tags *and* both --tags and another refspec appear on the command-line; (b) because any extra entries would be deleted later by the call to ref_remove_duplicates() anyway. But, to avoid extra work and extra memory usage, and to make the implementation better match the intention, change the algorithm slightly: compute the opportunistic refspecs based only on the command-line arguments, storing the results into a separate temporary list. Then add the tags (which have to come earlier in the list so that they are not de-duped in favor of an opportunistic entry). Then concatenate the temporary list onto the main list. This change will also make later changes easier. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

fetch --tags: fetch tags *in addition to* other stuff Previously, fetch's "--tags" option was considered equivalent to specifying the refspec "refs/tags/*:refs/tags/*" on the command line; in particular, it caused the remote.<name>.refspec configuration to be ignored. But it is not very useful to fetch tags without also fetching other references, whereas it *is* quite useful to be able to fetch tags *in addition to* other references. So change the semantics of this option to do the latter. If a user wants to fetch *only* tags, then it is still possible to specifying an explicit refspec: git fetch <remote> 'refs/tags/*:refs/tags/*' Please note that the documentation prior to 1.8.0.3 was ambiguous about this aspect of "fetch --tags" behavior.

Make git-fetch follow tags we already have objects for sooner If autofollowing of tags is enabled, we see a new tag on the remote that we don't have, and we already have the SHA-1 object that the tag is peeled to, then we can fetch the tag while we are fetching the other objects on the first connection. This is a slight optimization for projects that have a habit of tagging a release commit after most users have already seen and downloaded that commit object through a prior fetch session. In such cases the users may still find new objects in branch heads, but the new tag will now also be part of the first pack transfer and the subsequent connection to autofollow tags is not required. Currently git.git does not benefit from this optimization as any release usually gets a new commit at the same time that it gets a new release tag, however git-gui.git and many other projects are in the habit of tagging fairly old commits. Users who did not already have the tagged commit still require opening a second connection to autofollow the tag, as we are unable to determine on the client side if $tag^{} will be sent to the client during the first transfer or not. Such computation must be performed on the remote side of the connection and is deferred to another series of changes. Signed-off-by: Shawn O.

fetch: report ref storage DF errors more accurately When we fail to store a fetched ref, we recommend that the user try running "git prune" to remove up any old refs that have been deleted by the remote, which would clear up any DF conflicts. However, ref storage might fail for other reasons (e.g., permissions problems) in which case the advice is useless and misleading. This patch detects when there is an actual DF situation and only issues the advice when one is found. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

submodules: recursive fetch also checks new tags for submodule commits Since 88a21979c (fetch/pull: recurse into submodules when necessary) all fetched commits are examined if they contain submodule changes (unless configuration or command line options inhibit that). If a newly recorded submodule commit is not present in the submodule, a fetch is run inside it to download that commit. Checking new refs was done in an else branch where it wasn't executed for tags. This normally isn't a problem because tags are only fetched with the branches they live on, then checking the new commits in the fetched branches for submodule commits will also process all tags. But when a specific tag is fetched (or the refspec contains refs/tags/) commits only reachable by tags won't be searched for submodule commits, which is a bug. Fix that by moving the code outside the if/else construct to handle new tags just like any other ref. The performance impact of adding tags that most of the time lie on a branch which is checked anyway for new submodule commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop checking for updated submodules) all ref-tips are collected first and then fed to a single rev-list.

fetch/pull: recurse into submodules when necessary To be able to access all commits of populated submodules referenced by the superproject it is sufficient to only then let "git fetch" recurse into a submodule when the new commits fetched in the superproject record new commits for it. Having these commits present is extremely useful when using the "--submodule" option to "git diff" (which is what "git gui" and "gitk" do since 1.6.6), as all submodule commits needed for creating a descriptive output can be accessed. Also merging submodule commits (added in 1.7.3) depends on the submodule commits in question being present to work. Last but not least this enables disconnected operation when using submodules, as all commits necessary for a successful "git submodule update -N" will have been fetched automatically. So we choose this mode as the default for fetch and pull. Before a new or changed ref from upstream is updated in update_local_ref() "git rev-list <new-sha1> --not --branches --remotes" is used to determine all newly fetched commits. These are then walked and diffed against their parent(s) to see if a submodule has been changed. If that is the case, its path is stored to be fetched after the superproject fetch is completed. Using the "--recurse-submodules" or the "--no-recurse-submodules" option disables the examination of the fetched refs because the result will be ignored anyway. There is currently no infrastructure for storing deleted and new submodules in the .git directory of the superproject. That's why fetch and pull for now only fetch submodules that are already checked out and are not renamed. In t7403 the "--no-recurse-submodules" argument had to be added to "git pull" to avoid failure because of the moved upstream submodule repo.

D/F conflicts on tracking branch ref names In either case, there should already have been an error message. In case '1', hopefully enough information has already been given that the user can fix it. In the case of '2', we can hint that the user can clean up their tracking branch area by using 'git remote prune'. Note that we don't actually know _which_ case we have, so the user will receive the hint in case 1, as well.

refactor "ref->merge" flag Each "struct ref" has a boolean flag that is set by the fetch code to determine whether the ref should be marked as "not-for-merge" or not when we write it out to FETCH_HEAD. It would be useful to turn this boolean into a tri-state, with the third state meaning "do not bother writing it out to FETCH_HEAD at all". That would let us add extra refs to the set of refs to be stored (e.g., to store copies of things we fetched) without impacting FETCH_HEAD. This patch turns it into an enum that covers the tri-state case, and hopefully makes the code more explicit and easier to read.

fetch: Strip usernames from url's before storing them When pulling from a remote, the full URL including username is by default added to the commit message. Since it adds very little value but could be used by malicious people to glean valid usernames (with matching hostnames), we're far better off just stripping the username before storing the remote URL locally. Note that this patch has no lasting visible effect when "git pull" does not create a merge commit. It simply alters what gets written to .git/FETCH_HEAD, which is used by "git merge" to automagically create its messages.

Allow programs to not depend on remotes having urls For fetch and ls-remote, which use the first url of a remote, have transport_get() determine this by passing a remote and passing NULL for the url. For push, which uses every url of a remote, use each url in turn if there are any, and use NULL if there are none. This will allow the transport code to do something different if the location is not specified with a url. Also, have the message for a fetch say "foreign" if there is no url.

fetch: verify we have everything we need before updating our ref The "git fetch" command works in two phases. The remote side tells us what objects are at the tip of the refs we are fetching from, and transfers the objects missing from our side. After storing the objects in our repository, we update our remote tracking branches to point at the updated tips of the refs. A broken or malicious remote side could send a perfectly well-formed pack data during the object transfer phase, but there is no guarantee that the given data actually fill the gap between the objects we originally had and the refs we are updating to. Although this kind of breakage can be caught by running fsck after a fetch, it is much cheaper to verify that everything that is reachable from the tips of the refs we fetched are indeed fully connected to the tips of our current set of refs before we update them.

fetch: support fetching from a shallow repository This patch just put together pieces from the 8 steps patch. We stop at step 7 and reject refs that require new shallow commits. Note that, by rejecting refs that require new shallow commits, we leave dangling objects in the repo, which become "object islands" by the next "git fetch" of the same source. If the first fetch our "ours" set is zero and we do practically nothing at step 7, "ours" is full at the next fetch and we may need to walk through commits for reachability test.

fetch: report ref storage DF errors more accurately When we fail to store a fetched ref, we recommend that the user try running "git prune" to remove up any old refs that have been deleted by the remote, which would clear up any DF conflicts.

git-fetch: avoid local fetching from alternate (again) Back in e3c6f240fd9c5bdeb33f2d47adc859f37935e2df Junio taught git-fetch to avoid copying objects when we are fetching from a repository that is already registered as an alternate object database. In such a case there is no reason to copy any objects as we can already obtain them through the alternate. However we need to ensure the objects are all reachable, so we run `git rev-list --objects $theirs --not --all` to verify this. If any object is missing or unreadable then we need to fetch/copy the objects from the remote. When a missing object is detected the git-rev-list process will exit with a non-zero exit status, making this condition quite easy to detect. Although git-fetch is currently a builtin (and so is rev-list) we cannot invoke the traverse_objects() API at this point in the transport code. The object walker within traverse_objects() calls die() as soon as it finds an object it cannot read. If that happens we want to resume the fetch process by calling do_fetch_pack(). To get around this we spawn git-rev-list into a background process to prevent a die() from killing the foreground fetch process, thus allowing the fetch process to resume into do_fetch_pack() if copying is necessary. We aren't interested in the output of rev-list (a list of SHA-1 object names that are reachable) or its errors (a "spurious" error about an object not being found as we need to copy it) so we redirect both stdout and stderr to /dev/null. We run this git-rev-list based check before any fetch as we may already have the necessary objects local from a prior fetch. If we don't then its very likely the first $theirs object listed on the command line won't exist locally and git-rev-list will die very quickly, allowing us to start the network transfer. This test even on remote URLs may save bandwidth if someone runs `git pull origin`, sees a merge conflict, resets out, then redoes the same pull just a short time later. If the remote hasn't changed between the two pulls and the local repository hasn't had git-gc run in it then there is probably no need to perform network transfer as all of the objects are local.

* We would want to bypass the object transfer altogether if
quickfetch(): Prevent overflow of the rev-list command line quickfetch() calls rev-list to check whether the objects we are about to fetch are already present in the repo (if so, we can skip the object fetch). However, when there are many (~1000) refs to be fetched, the rev-list command line grows larger than the maximum command line size on some systems (32K in Windows). This causes rev-list to fail, making quickfetch() return non-zero, which unnecessarily triggers the transport machinery. This somehow causes fetch to fail with an exit code. By using the --stdin option to rev-list (and feeding the object list to its standard input), we prevent the overflow of the rev-list command line, which causes quickfetch(), and subsequently the overall fetch, to succeed. However, using rev-list --stdin is not entirely straightforward: rev-list terminates immediately when encountering an unknown object, which can trigger SIGPIPE if we are still writing object's to its standard input. We therefore temporarily ignore SIGPIPE so that the fetch process is not terminated. The patch also contains a testcase to verify the fix (note that before the patch, the testcase would only fail on msysGit).

Remove pack.keep after ref updates in git-fetch If we are using a native packfile to perform a git-fetch invocation and the received packfile contained more than the configured limits of fetch.unpackLimit/transfer.unpackLimit then index-pack will output a single line saying "keep\t$sha1\n" to stdout. This line needs to be captured and retained so we can delete the corresponding .keep file ("$GIT_DIR/objects/pack/pack-$sha1.keep") once all refs have been safely updated. This trick has long been in use with git-fetch.sh and its lower level helper git-fetch--tool as a way to allow index-pack to save the new packfile before the refs have been updated and yet avoid a race with any concurrently running git-repack process.

Make fetch a builtin Thanks to Johannes Schindelin for review and fixes, and Julian Phillips for the original C translation. This changes a few small bits of behavior: branch.<name>.merge is parsed as if it were the lhs of a fetch refspec, and does not have to exactly match the actual lhs of a refspec, so long as it is a valid abbreviation for the same ref. branch.<name>.merge is no longer ignored if the remote is configured with a branches/* file. Neither behavior is useful, because there can only be one ref that gets fetched, but this is more consistant. Also, fetch prints different information to standard out.

fetch: honor the user-provided refspecs when pruning refs If the user gave us refspecs on the command line, we should use those when deciding whether to prune a ref instead of relying on the refspecs in the config. Previously, running git fetch --prune origin refs/heads/master:refs/remotes/origin/master would delete every other ref under the origin namespace because we were using the refspec to filter the available refs but using the configured refspec to figure out if a ref had been deleted on the remote. This is clearly the wrong thing to do. Change prune_refs and get_stale_heads to simply accept a list of references and a list of refspecs. The caller of either function needs to decide what refspecs should be used to decide whether a ref is stale.

Fix fetch/pull when run without --update-head-ok Some confusing tutorials suggested that it would be a good idea to fetch into the current branch with something like this: git fetch origin master:master (or even worse: the same command line with "pull" instead of "fetch"). While it might make sense to store what you want to pull, it typically is plain wrong when the current branch is "master". This should only be allowed when (an incorrect) "git pull origin master:master" tries to work around by giving --update-head-ok to underlying "git fetch", and otherwise we should refuse it, but somewhere along the lines we lost that behavior. The check for the current branch is now _only_ performed in non-bare repositories, which is an improvement from the original behaviour.

fetch --all/--multiple: keep all the fetched branch information Since "git fetch" learned "--all" and "--multiple" options, it has become tempting for users to say "git pull --all". Even though it may fetch from remotes that do not need to be fetched from for merging with the current branch, it is handy. "git fetch" however clears the list of fetched branches every time it contacts a different remote. Unless the current branch is configured to merge with a branch from a remote that happens to be the last in the list of remotes that are contacted, "git pull" that fetches from multiple remotes will not be able to find the branch it should be merging with. Make "fetch" clear FETCH_HEAD (unless --append is given) and then append the list of branches fetched to it (even when --append is not given). That way, "pull" will be able to find the data for the branch being merged in FETCH_HEAD no matter where the remote appears in the list of remotes to be contacted by "git fetch".

While this hack works OK for a single request, it breaks when the transport needs to make more than one requests. transport->data that used to hold necessary information for the specific helper to work correctly is destroyed during the take-over process. One codepath that this matters is "git fetch" in auto-follow mode; when it does not get all the tags that ought to point at the history it got (which can be determined by looking at the peeled tags in the initial advertisement) from the primary transfer, it internally makes a second request to complete the fetch. Because "take-over" hack has already destroyed the data necessary to talk to the transport helper by the time this happens, the second request cannot make a request to the helper to make another connection to fetch these additional tags. Mark such a transport as "cannot_reuse", and use a separate transport to perform the backfill fetch in order to work around this breakage. Note that this problem does not manifest itself when running t5802, because our upload-pack gives you all the necessary auto-followed tags during the primary transfer. You would need to step through "git fetch" in a debugger, stop immediately after the primary transfer finishes and writes these auto-followed tags, remove the tag references and repack/prune the repository to convince the "find-non-local-tags" procedure that the primary transfer failed to give us all the necessary tags, and then let it continue, in order to trigger the bug in the secondary transfer this patch fixes.

Refactor struct transport_ops inlined into struct transport Aside from reducing the code by 20 lines this refactoring removes a level of indirection when trying to access the operations of a given transport "instance", making the code clearer and easier to follow. It also has the nice effect of giving us the benefits of C99 style struct initialization (namely ".fetch = X") without requiring that level of language support from our compiler. We don't need to worry about new operation methods being added as they will now be NULL'd out automatically by the xcalloc() we use to create the new struct transport we supply to the caller. This pattern already exists in struct walker, so we already have a precedent for it in Git. We also don't really need to worry about any sort of performance decreases that may occur as a result of filling out 4-8 op pointers when we make a "struct transport". The extra few CPU cycles this requires over filling in the "struct transport_ops" is killed by the time it will take Git to actually *use* one of those functions, as most transport operations are going over the wire or will be copying object data locally between two directories.

Fix fetch/pull when run without --update-head-ok Some confusing tutorials suggested that it would be a good idea to fetch into the current branch with something like this: git fetch origin master:master (or even worse: the same command line with "pull" instead of "fetch"). While it might make sense to store what you want to pull, it typically is plain wrong when the current branch is "master". This should only be allowed when (an incorrect) "git pull origin master:master" tries to work around by giving --update-head-ok to underlying "git fetch", and otherwise we should refuse it, but somewhere along the lines we lost that behavior. The check for the current branch is now _only_ performed in non-bare repositories, which is an improvement from the original behaviour.

Teach git-fetch to exploit server side automatic tag following If the remote peer upload-pack process supports the include-tag protocol extension then we can avoid running a second fetch cycle on the client side by letting the server send us the annotated tags along with the objects it is packing for us. In the following graph we can now fetch both "tag1" and "tag2" on the same connection that we fetched "master" from the remote when we only have L available on the local side: T - tag1 S - tag2 / / L - o ------ o ------ B \ \ \ \ origin/master master The objects for "tag1" are implicitly downloaded without our direct knowledge. The existing "quickfetch" optimization within git-fetch discovers that tag1 is complete after the first connection and does not open a second connection. Signed-off-by: Shawn O.

fetch --prune: prune only based on explicit refspecs The old behavior of "fetch --prune" was to prune whatever was being fetched. In particular, "fetch --prune --tags" caused tags not only to be fetched, but also to be pruned. This is inappropriate because there is only one tags namespace that is shared among the local repository and all remotes. Therefore, if the user defines a local tag and then runs "git fetch --prune --tags", then the local tag is deleted. Moreover, "--prune" and "--tags" can also be configured via fetch.prune / remote.<name>.prune and remote.<name>.tagopt, making it even less obvious that an invocation of "git fetch" could result in tag lossage. Since the command "git remote update" invokes "git fetch", it had the same problem. The command "git remote prune", on the other hand, disregarded the setting of remote.<name>.tagopt, and so its behavior was inconsistent with that of the other commands. So the old behavior made it too easy to lose tags. To fix this problem, change "fetch --prune" to prune references based only on refspecs specified explicitly by the user, either on the command line or via remote.<name>.fetch. Thus, tags are no longer made subject to pruning by the --tags option or the remote.<name>.tagopt setting. However, tags *are* still subject to pruning if they are fetched as part of a refspec, and that is good. For example: * On the command line, git fetch --prune 'refs/tags/*:refs/tags/*' causes tags, and only tags, to be fetched and pruned, and is therefore a simple way for the user to get the equivalent of the old behavior of "--prune --tag". * For a remote that was configured with the "--mirror" option, the configuration is set to include [remote "name"] fetch = +refs/*:refs/* , which causes tags to be subject to pruning along with all other references.

fetch --tags: fetch tags *in addition to* other stuff Previously, fetch's "--tags" option was considered equivalent to specifying the refspec "refs/tags/*:refs/tags/*" on the command line; in particular, it caused the remote.<name>.refspec configuration to be ignored. But it is not very useful to fetch tags without also fetching other references, whereas it *is* quite useful to be able to fetch tags *in addition to* other references. So change the semantics of this option to do the latter. If a user wants to fetch *only* tags, then it is still possible to specifying an explicit refspec: git fetch <remote> 'refs/tags/*:refs/tags/*' Please note that the documentation prior to 1.8.0.3 was ambiguous about this aspect of "fetch --tags" behavior.

Make fetch a builtin Thanks to Johannes Schindelin for review and fixes, and Julian Phillips for the original C translation. This changes a few small bits of behavior: branch.<name>.merge is parsed as if it were the lhs of a fetch refspec, and does not have to exactly match the actual lhs of a refspec, so long as it is a valid abbreviation for the same ref. branch.<name>.merge is no longer ignored if the remote is configured with a branches/* file. Neither behavior is useful, because there can only be one ref that gets fetched, but this is more consistant. Also, fetch prints different information to standard out.

fetch/pull: Add the --recurse-submodules option Until now you had to call "git submodule update" (without -N|--no-fetch option) or something like "git submodule foreach git fetch" to fetch new commits in populated submodules from their remote. This could lead to "(commits not present)" messages in the output of "git diff --submodule" (which is used by "git gui" and "gitk") after fetching or pulling new commits in the superproject and is an obstacle for implementing recursive checkout of submodules. Also "git submodule update" cannot fetch changes when disconnected, so it was very easy to forget to fetch the submodule changes before disconnecting only to discover later that they are needed. This patch adds the "--recurse-submodules" option to recursively fetch each populated submodule from the url configured in the .git/config of the submodule at the end of each "git fetch" or during "git pull" in the superproject. The submodule paths are taken from the index. The hidden option "--submodule-prefix" is added to "git fetch" to be able to print out the full paths of nested submodules.

fetch --all/--multiple: keep all the fetched branch information Since "git fetch" learned "--all" and "--multiple" options, it has become tempting for users to say "git pull --all". Even though it may fetch from remotes that do not need to be fetched from for merging with the current branch, it is handy. "git fetch" however clears the list of fetched branches every time it contacts a different remote. Unless the current branch is configured to merge with a branch from a remote that happens to be the last in the list of remotes that are contacted, "git pull" that fetches from multiple remotes will not be able to find the branch it should be merging with. Make "fetch" clear FETCH_HEAD (unless --append is given) and then append the list of branches fetched to it (even when --append is not given). That way, "pull" will be able to find the data for the branch being merged in FETCH_HEAD no matter where the remote appears in the list of remotes to be contacted by "git fetch".

Give error when no remote is configured When there's no explicitly-named remote, we use the remote specified for the current branch, which in turn defaults to "origin". But it this case should require the remote to actually be configured, and not fall back to the path "origin". Possibly, the config file's "remote = something" should require the something to be a configured remote instead of a bare repository URL, but we actually test with a bare repository URL. In fetch, we were giving the sensible error message when coming up with a URL failed, but this wasn't actually reachable, so move that error up and use it when appropriate.

Some people want to always run "git fetch --prune". To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune": - "fetch.prune" allows to enable prune for all fetch operations. - "remote.<name>.prune" allows to change the behaviour per remote. The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default. Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

refactor signal handling for cleanup functions The current code is very inconsistent about which signals are caught for doing cleanup of temporary files and lock files. Some callsites checked only SIGINT, while others checked a variety of death-dealing signals. This patch factors out those signals to a single function, and then calls it everywhere. For some sites, that means this is a simple clean up. For others, it is an improvement in that they will now properly clean themselves up after a larger variety of signals.

Make fetch a builtin Thanks to Johannes Schindelin for review and fixes, and Julian Phillips for the original C translation. This changes a few small bits of behavior: branch.<name>.merge is parsed as if it were the lhs of a fetch refspec, and does not have to exactly match the actual lhs of a refspec, so long as it is a valid abbreviation for the same ref. branch.<name>.merge is no longer ignored if the remote is configured with a branches/* file. Neither behavior is useful, because there can only be one ref that gets fetched, but this is more consistant. Also, fetch prints different information to standard out.

add packet tracing debug code This shows a trace of all packets coming in or out of a given program. This can help with debugging object negotiation or other protocol issues. To keep the code changes simple, we operate at the lowest level, meaning we don't necessarily understand what's in the packets. The one exception is a packet starting with "PACK", which causes us to skip that packet and turn off tracing (since the gigantic pack data will not be interesting to read, at least not in the trace format). We show both written and read packets. In the local case, this may mean you will see packets twice (written by the sender and read by the receiver). However, for cases where the other end is remote, this allows you to see the full conversation. Packet tracing can be enabled with GIT_TRACE_PACKET=<foo>, where <foo> takes the same arguments as GIT_TRACE.

fetch: make --prune configurable Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever. Some people want to always run "git fetch --prune". To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune": - "fetch.prune" allows to enable prune for all fetch operations. - "remote.<name>.prune" allows to change the behaviour per remote. The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default. Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

fetch: add --unshallow for turning shallow repo into complete one The user can do --depth=2147483647 (*) for restoring complete repo now. But it's hard to remember. Any other numbers larger than the longest commit chain in the repository would also do, but some guessing may be involved. Make easy-to-remember --unshallow an alias for --depth=2147483647. Make upload-pack recognize this special number as infinite depth. The effect is essentially the same as before, except that upload-pack is more efficient because it does not have to traverse to the bottom anymore. The chance of a user actually wanting exactly 2147483647 commits depth, not infinite, on a repository with a history that long, is probably too small to consider. The client can learn to add or subtract one commit to avoid the special treatment when that actually happens. (*) This is the largest positive number a 32-bit signed integer can contain. JGit and older C Git store depth as "int" so both are OK with this number. Dulwich does not support shallow clone.

fetch: run gc --auto after fetching We generally try to run "gc --auto" after any commands that might introduce a large number of new objects. An obvious place to do so is after running "fetch", which may introduce new loose objects or packs (depending on the size of the fetch). While an active developer repository will probably eventually trigger a "gc --auto" on another action (e.g., git-rebase), there are two good reasons why it is nicer to do it at fetch time: 1. Read-only repositories which track an upstream (e.g., a continuous integration server which fetches and builds, but never makes new commits) will accrue loose objects and small packs, but never coalesce them into a more efficient larger pack. 2. Fetching is often already perceived to be slow to the user, since they have to wait on the network. It's much more pleasant to include a potentially slow auto-gc as part of the already-long network fetch than in the middle of productive work with git-rebase or similar.
