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/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.

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.

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/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.

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.

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.

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.

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 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.

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.

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.

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: 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.

fetch: report local storage errors in status table Previously, if there was an error while storing a local tracking ref, the low-level functions would report an error, but fetch's status output wouldn't indicate any problem. E.g., imagine you have an old "refs/remotes/origin/foo/bar" but upstream has deleted "foo/bar" in favor of a new branch "foo". You would get output like this: error: there are still refs under 'refs/remotes/origin/foo' From $url_of_repo * [new branch] foo -> origin/foo With this patch, the output takes into account the status of updating the local ref: error: there are still refs under 'refs/remotes/origin/foo' From $url_of_repo !

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.

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: report local storage errors in status table Previously, if there was an error while storing a local tracking ref, the low-level functions would report an error, but fetch's status output wouldn't indicate any problem. E.g., imagine you have an old "refs/remotes/origin/foo/bar" but upstream has deleted "foo/bar" in favor of a new branch "foo". You would get output like this: error: there are still refs under 'refs/remotes/origin/foo' From $url_of_repo * [new branch] foo -> origin/foo With this patch, the output takes into account the status of updating the local ref: error: there are still refs under 'refs/remotes/origin/foo' From $url_of_repo !

fetch: give a hint to the user when local refs fail to update There are basically two categories of update failures for local refs: 1. problems outside of git, like disk full, bad permissions, etc. 2. 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. In this case the suggestion won't do any good, but hopefully the user is smart enough to figure out that it's just a hint.

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.

On top of that, the display formatting was different from all of the other cases, probably owing to the fact that nobody had ever actually seen the output. This patch harmonizes the output with the other cases and moves the detection of this case into store_updated_refs, where we can actually trigger it.

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: 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.

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.

fetch: give a hint to the user when local refs fail to update There are basically two categories of update failures for local refs: 1. problems outside of git, like disk full, bad permissions, etc. 2. 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. In this case the suggestion won't do any good, but hopefully the user is smart enough to figure out that it's just a hint.

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.

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.

use write_str_in_full helper to avoid literal string lengths In 2d14d65 (Use a clearer style to issue commands to remote helpers, 2009-09-03) I happened to notice two changes like this: - write_in_full(helper->in, "list\n", 5); + + strbuf_addstr(&buf, "list\n"); + write_in_full(helper->in, buf.buf, buf.len); + strbuf_reset(&buf); IMHO, it would be better to define a new function, static inline ssize_t write_str_in_full(int fd, const char *str) { return write_in_full(fd, str, strlen(str)); } and then use it like this: - strbuf_addstr(&buf, "list\n"); - write_in_full(helper->in, buf.buf, buf.len); - strbuf_reset(&buf); + write_str_in_full(helper->in, "list\n"); Thus not requiring the added allocation, and still avoiding the maintenance risk of literal string lengths. These days, compilers are good enough that strlen("literal") imposes no run-time cost.

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.

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>

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: give a hint to the user when local refs fail to update There are basically two categories of update failures for local refs: 1. problems outside of git, like disk full, bad permissions, etc. 2. 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. In this case the suggestion won't do any good, but hopefully the user is smart enough to figure out that it's just a hint.

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. It was unfortunately lost when git-fetch.sh was converted to pure C and fetch--tool was no longer being invoked. Signed-off-by: Shawn O.

Teach git-fetch to grab a tag at the same time as a commit If the situation is the following on the remote and L is the common base between both sides: T - tag1 S - tag2 / / L - A - O - O - B \ \ origin/master master and we have decided to fetch "master" to acquire the range L..B we can also nab tag S at the same time during the first connection, as we can clearly see from the refs advertised by upload-pack that S^{} = B and master = B. Unfortunately we still cannot nab T at the same time as we are not able to see that T^{} will also be in the range implied by L..B. Such computations must be performed on the remote side (not yet supported) or on the client side as post-processing (the current behavior). This optimization is an extension of the previous one in that it helps on projects which tend to publish both a new commit and a new tag, then lay idle for a while before publishing anything else. Most followers are able to download both the new commit and the new tag in one connection, rather than two. git.git tends to follow such patterns with its roughly once-daily updates from Junio. A protocol extension and additional server side logic would be necessary to also ensure T is grabbed on the first connection. Signed-off-by: Shawn O.

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.

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.

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.

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.

Avoid printing unnecessary warnings during fetch and push If a transport doesn't support an option we already are telling the higher level application (fetch or push) that the option is not valid by sending back a >0 return value from transport_set_option so there's not a strong motivation to have the function perform the output itself. Instead we should let the higher level application do the output if it is necessary. This avoids always telling the user that depth isn't supported on HTTP urls even when they did not pass a --depth option to git-fetch. If the user passes an option and the option value is invalid we now properly die in git-fetch instead of just spitting out a message and running anyway. This mimics prior behavior better where incorrect/malformed options are not accepted by the process. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Rewrite dynamic structure initializations to runtime assignment Unfortunately, there are still plenty of production systems with vendor compilers that choke unless all compound declarations can be determined statically at compile time, for example hpux10.20 (I can provide a comprehensive list of our supported platforms that exhibit this problem if necessary). This patch simply breaks apart any compound declarations with dynamic initialisation expressions, and moves the initialisation until after the last declaration in the same block, in all the places necessary to have the offending compilers accept the code.

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.

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.

remote.c: Fix overtight refspec validation We tightened the refspec validation code in an earlier commit ef00d15 (Tighten refspec processing, 2008-03-17) per my suggestion, but the suggestion was misguided to begin with and it broke this usage: $ git push origin HEAD~12:master The syntax of push refspecs and fetch refspecs are similar in that they are both colon separated LHS and RHS (possibly prefixed with a + to force), but the similarity ends there. For example, LHS in a push refspec can be anything that evaluates to a valid object name at runtime (except when colon and RHS is missing, or it is a glob), while it must be a valid-looking refname in a fetch refspec. To validate them correctly, the caller needs to be able to say which kind of refspecs they are. It is unreasonable to keep a single interface that cannot tell which kind it is dealing with, and ask it to behave sensibly. This commit separates the parsing of the two into different functions, and clarifies the code to implement the parsing proper (i.e. splitting into two parts, making sure both sides are wildcard or neither side is). This happens to also allow pushing a commit named with the esoteric "look for that string" syntax: $ git push ../test.git ':/remote.c: Fix overtight refspec:master' Signed-off-by: Junio C Hamano <gitster@pobox.com>

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/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.
