Jens Lehmann	6a5cedac87	diff/status: print submodule path when looking for changes fails diff and status run "git status --porcelain" inside each populated submodule to see if it contains changes (unless told not to do so via config or command line option). When that fails, e.g. due to a corrupt submodule .git directory, it just prints "git status --porcelain failed" or "Could not run git status --porcelain" without giving the user a clue where that happened. Add '"in submodule %s", path' to these error strings to tell the user where exactly the problem occurred.

Brad King	80988783c8	submodule: Search for merges only at end of recursive merge The submodule merge search is not useful during virtual merges because the results cannot be used automatically. Furthermore any suggestions made by the search may apply to commits different than HEAD:sub and MERGE_HEAD:sub, thus confusing the user. Skip searching for submodule merges during a virtual merge such as that between B and C while merging the heads of: B---BC / \ / A X \ / \ C---CB Run the search only when the recursion level is zero (!o->call_depth).

Jeff King	c1189caeaf	refactor argv_array into generic code The submodule code recently grew generic code to build a dynamic argv array. Many other parts of the code can reuse this, too, so let's make it generically available. There are two enhancements not found in the original code: 1. We now handle the NULL-termination invariant properly, even when no strings have been pushed (before, you could have an empty, NULL argv). This was not a problem for the submodule code, which always pushed at least one argument, but was not sufficiently safe for generic code. 2. There is a formatted variant of the "push" function. This is a convenience function which was not needed by the submodule code, but will make it easier to port other users to the new code.

Jeff King	6859de45a9	fetch: avoid quadratic loop checking for updated submodules Recent versions of git can be slow to fetch repositories with a large number of refs (or when they already have a large number of refs). For example, GitHub makes pull-requests available as refs, which can lead to a large number of available refs. This slowness goes away when submodule recursion is turned off: $ git ls-remote git://github.com/rails/rails.git \| wc -l 3034 [this takes ~10 seconds of CPU time to complete] git fetch --recurse-submodules=no \ git://github.com/rails/rails.git "refs/:refs/" [this still isn't done after 10 _minutes_ of pegging the CPU] git fetch \ git://github.com/rails/rails.git "refs/:refs/" You can produce a quicker and simpler test case like this: doit() { head=`git rev-parse HEAD` for i in `seq 1 $1`; do echo $head refs/heads/ref$i done >.git/packed-refs echo "==> $1" rm -rf dest git init -q --bare dest && (cd dest && time git.compile fetch -q .. refs/:refs/) } rm -rf repo git init -q repo && cd repo && >file && git add file && git commit -q -m one doit 100 doit 200 doit 400 doit 800 doit 1600 doit 3200 Which yields timings like: # refs seconds of CPU 100 0.06 200 0.24 400 0.95 800 3.39 1600 13.66 3200 54.09 Notice that although the number of refs doubles in each trial, the CPU time spent quadruples. The problem is that the submodule recursion code works something like: - for each ref we fetch - for each commit in git rev-list $new_sha1 --not --all - add modified submodules to list - fetch any newly referenced submodules But that means if we fetch N refs, we start N revision walks. Worse, because we use "--all", the number of refs we must process that constitute "--all" keeps growing, too. And you end up doing O(N^2) ref resolutions. Instead, this patch structures the code like this: - for each sha1 we already have - add $old_sha1 to list $old - for each ref we fetch - add $new_sha1 to list $new - for each commit in git rev-list $new --not $old - add modified submodules to list - fetch any newly referenced submodules This yields timings like: # refs seconds of CPU 100 0.00 200 0.04 400 0.04 800 0.10 1600 0.21 3200 0.39 Note that the amount of effort doubles as the number of refs doubles. Similarly, the fetch of rails.git takes about as much time as it does with --recurse-submodules=no.

Jens Lehmann	18322badc2	fetch: skip on-demand checking when no submodules are configured It makes no sense to do the - possibly very expensive - call to "rev-list <new-ref-sha1> --not --all" in check_for_new_submodule_commits() when there aren't any submodules configured. Leave check_for_new_submodule_commits() early when no name <-> path mappings for submodules are found in the configuration. To make that work reading the configuration had to be moved further up in cmd_fetch(), as doing that after the actual fetch of the superproject was too late.

Fredrik Gustafsson	d2b17b3220	push: Don't push a repository with unpushed submodules When working with submodules it is easy to forget to push a submodule to the server but pushing a super-project that contains a commit for that submodule. The result is that the superproject points at a submodule commit that is not available on the server. This adds the option --recurse-submodules=check to push. When using this option git will check that all submodule commits that are about to be pushed are present on a remote of the submodule. To be able to use a combined diff, disabling a diff callback has been removed from combined-diff.c.

Jens Lehmann	ea2d325b88	fetch: Also fetch submodules in subdirectories in on-demand mode When on-demand mode was active examining the new commits just fetched in the superproject (to check if they record commits for submodules which are not downloaded yet) wasn't done recursively. Because of that fetch did not recursively fetch submodules living in subdirectories even when it should have.

Jens Lehmann	d4e98b581b	Submodules: Don't parse .gitmodules when it contains, merge conflicts Commands like "git status", "git diff" and "git fetch" would fail when the .gitmodules file contained merge conflicts because the config parser would call die() when hitting the conflict markers: "fatal: bad config file line <n> in <path>/.gitmodules" While this behavior was on the safe side, it is really unhelpful to the user to have commands like status and diff fail, as these are needed to find out what's going on. And the error message is only mildly helpful, as it points to the right file but doesn't mention that it is unmerged. Users of git gui were not shown any conflicts at all when this happened. Improve the situation by checking if the index records .gitmodules as unmerged. When that is the case we can't make any assumptions about the configuration to be found there after the merge conflict is resolved by the user, so assume that all recursion is disabled unless .git/config or the global config say otherwise. As soon as the merge conflict is resolved and the .gitmodules file has been staged subsequent commands again honor any configuration done there.

Jonathan Nieder	808a95dcad	diff --submodule: split into bite-sized pieces Introduce two functions: - prepare_submodule_summary prepares the revision walker to list changes in a submodule. That is, it: * finds merge bases between the commits pointed to this path from before ("left") and after ("right") the change; * checks whether this is a fast-forward or fast-backward; * prepares a revision walk to list commits in the symmetric difference between the commits at each endpoint. It returns nonzero on error. - print_submodule_summary runs the revision walk and saves the result to a strbuf in --left-right format. The goal is just readability. No functional change intended.

Jens Lehmann	88a21979c5	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.

Jens Lehmann	c1a3c3640d	Submodules: Add the "fetchRecurseSubmodules" config option The new boolean "fetchRecurseSubmodules" config option controls the behavior for "git fetch" and "git pull". It specifies if these commands should recurse into submodules and fetch new commits there too and can be set separately for each submodule. In the .gitmodules file "submodule.<name>.fetchRecurseSubmodules" entries are read before looking for them in .git/config. Thus settings found in .git/config will override those from .gitmodules, thereby allowing the user to ignore settings given by the remote side while also letting upstream set reasonable defaults for those users who don't have special needs. This configuration can be overridden by the command line option "--[no-]recurse-submodules" of "git fetch" and "git pull".

Jens Lehmann	7dce19d374	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.

Johannes Schindelin	be4f2b408e	Add the 'diff.ignoreSubmodules' config setting When you have a lot of submodules checked out, the time penalty to check for dirty submodules can easily imply a multiplication of the total time by the factor 20. This makes the difference between almost instantaneous (< 2 seconds) and unbearably slow (> 50 seconds) here, since the disk caches are constantly overloaded. To this end, the submodule..ignore config option was introduced, but it is per-submodule. This commit introduces a global config setting to set a default (porcelain) value for the --ignore-submodules option, keeping the default at 'none'. It can be overridden by the submodule..ignore setting and by the --ignore-submodules option. Incidentally, this commit fixes an issue with the overriding logic: multiple --ignore-submodules options would not clear the previously set flags.

Jens Lehmann	aee9c7d654	Submodules: Add the new "ignore" config option for diff and status The new "ignore" config option controls the default behavior for "git status" and the diff family. It specifies under what circumstances they consider submodules as modified and can be set separately for each submodule. The command line option "--ignore-submodules=" has been extended to accept the new parameter "none" for both status and diff. Users that chose submodules to get rid of long work tree scanning times might want to set the "dirty" option for those submodules. This brings back the pre 1.7.0 behavior, where submodule work trees were never scanned for modifications. By using "--ignore-submodules=none" on the command line the status and diff commands can be told to do a full scan. This option can be set to the following values (which have the same name and meaning as for the "--ignore-submodules" option of status and diff): "all": All changes to the submodule will be ignored. "dirty": Only differences of the commit recorded in the superproject and the submodules HEAD will be considered modifications, all changes to the work tree of the submodule will be ignored. When using this value, the submodule will not be scanned for work tree changes at all, leading to a performance benefit on large submodules. "untracked": Only untracked files in the submodules work tree are ignored, a changed HEAD and/or modified files in the submodule will mark it as modified. "none" (which is the default): Either untracked or modified files in a submodules work tree or a difference between the subdmodules HEAD and the commit recorded in the superproject will make it show up as changed. This value is added as a new parameter for the "--ignore-submodules" option of the diff family and "git status" so the user can override the settings in the configuration.

Heiko Voigt	68d03e4a6e	Implement automatic fast-forward merge for submodules This implements a simple merge strategy for submodule hashes. We check whether one side of the merge candidates is already contained in the other and then merge automatically. If both sides contain changes we search for a merge in the submodule. In case a single one exists we check that out and suggest it as the merge resolution. A list of candidates is returned when we find multiple merges that contain both sides of the changes. This is useful for a workflow in which the developers can publish topic branches in submodules and a separate maintainer merges them. In case the developers always wait until their branch gets merged before tracking them in the superproject all merges of branches that contain submodule changes will be resolved automatically. If developers choose to track their feature branch the maintainer might get a conflict but git will search the submodule for a merge and suggest it/them as a resolution.

Jens Lehmann	46a958b3da	Add the option "--ignore-submodules" to "git status" In some use cases it is not desirable that "git status" considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree (this was the behavior before 1.7.0). An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved when using the "dirty" parameter. And if you want to ignore any changes to submodules, you can now do that by using this option without parameters or with "all" (when the config option status.submodulesummary is set, using "all" will also suppress the output of the submodule summary). A new function handle_ignore_submodules_arg() is introduced to parse this option new to "git status" in a single location, as "git diff" already knew it.

Jens Lehmann	eee49b6ce4	Teach diff --submodule and status to handle .git files in submodules The simple test for an existing .git directory gives an incorrect result if .git is a file that records "gitdir: overthere". So for submodules that use a .git file, "git status" and the diff family - when the "--submodule" option is given - did assume the submodule was not populated at all when a .git file was used, thus generating wrong output or no output at all. This is fixed by using read_gitfile_gently() to get the correct location of the .git directory. While at it, is_submodule_modified() was cleaned up to use the "dir" member of "struct child_process" instead of setting the GIT_WORK_TREE and GIT_DIR environment variables.

Jens Lehmann	ee6fc514f2	Show submodules as modified when they contain a dirty work tree Until now a submodule only then showed up as modified in the supermodule when the last commit in the submodule differed from the one in the index or the diffed against commit of the superproject. A dirty work tree containing new untracked or modified files in a submodule was undetectable when looking at it from the superproject. Now git status and git diff (against the work tree) in the superproject will also display submodules as modified when they contain untracked or modified files, even if the compared ref matches the HEAD of the submodule.

David Aguilar	75b9a8a6d5	submodule.c: Squelch a "use before assignment" warning i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5493) compiler (and probably others) mistakenly thinks variable 'right' is used before assigned. Work around it by giving it a fake initialization. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Johannes Schindelin	752c0c2492	Add the --submodule option to the diff option family When you use the option --submodule=log you can see the submodule summaries inlined in the diff, instead of not-quite-helpful SHA-1 pairs. The format imitates what "git submodule summary" shows. To do that, <path>/.git/objects/ is added to the alternate object databases (if that directory exists). This option was requested by Jens Lehmann at the GitTogether in Berlin.
