submodule update: add --remote for submodule's upstream changes The current `update` command incorporates the superproject's gitlinked SHA-1 ($sha1) into the submodule HEAD ($subsha1). Depending on the options you use, it may checkout $sha1, rebase the $subsha1 onto $sha1, or merge $sha1 into $subsha1. This helps you keep up with changes in the upstream superproject. However, it's also useful to stay up to date with changes in the upstream subproject. Previous workflows for incorporating such changes include the ungainly: $ git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' With this patch, all of the useful functionality for incorporating superproject changes can be reused to incorporate upstream subproject updates. When you specify --remote, the target $sha1 is replaced with a $sha1 of the submodule's origin/master tracking branch. If you want to merge a different tracking branch, you can configure the `submodule.<name>.branch` option in `.gitmodules`. You can override the `.gitmodules` configuration setting for a particular superproject by configuring the option in that superproject's default configuration (using the usual configuration hierarchy, e.g. `.git/config`, `~/.gitconfig`, etc.). Previous use of submodule.<name>.branch ======================================= Because we're adding a new configuration option, it's a good idea to check if anyone else is already using the option. The foreach-pull example above was described by Ævar in commit f030c96d8643fa0a1a9b2bd9c2f36a77721fb61f Author: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Date: Fri May 21 16:10:10 2010 +0000 git-submodule foreach: Add $toplevel variable Gerrit uses the same interpretation for the setting, but because Gerrit has direct access to the subproject repositories, it updates the superproject repositories automatically when a subproject changes. Gerrit also accepts the special value '.', which it expands into the superproject's branch name. Although the --remote functionality is using `submodule.<name>.branch` slightly differently, the effect is the same. The foreach-pull example uses the option to record the name of the local branch to checkout before pulls. The tracking branch to be pulled is recorded in `.git/modules/<name>/config`, which was initialized by the module clone during `submodule add` or `submodule init`. Because the branch name stored in `submodule.<name>.branch` was likely the same as the branch name used during the initial `submodule add`, the same branch will be pulled in each workflow. Implementation details ====================== In order to ensure a current tracking branch state, `update --remote` fetches the submodule's remote repository before calculating the SHA-1. However, I didn't change the logic guarding the existing fetch: if test -z "$nofetch" then # Run fetch only if $sha1 isn't present or it # is not reachable from a ref. (clear_local_git_env; cd "$path" && ( (rev=$(git rev-list -n 1 $sha1 --not --all 2>/dev/null) && test -z "$rev") || git-fetch)) || die "$(eval_gettext "Unable to fetch in submodule path '\$path'")" fi There will not be a double-fetch, because the new $sha1 determined after the `--remote` triggered fetch should always exist in the repository. If it doesn't, it's because some racy process removed it from the submodule's repository and we *should* be re-fetching. Signed-off-by: W.

git-submodule.sh - Remove trailing / from URL if found git clone does not complain if a trailing '/' is included in the origin URL, but doing so causes resolution of a submodule's URL relative to the superproject to fail. Trailing /'s are likely when cloning locally using tab-completion, so the slash may appear in either superproject or submodule URL. So, ignore the trailing slash if it already exists in the superproject's URL, and don't record one for the submodule (which could itself have submodules...). The problem I'm trying to fix is that a number of folks have superprojects checked out where the recorded origin URL has a trailing /, and a submodule has its origin in a directory sitting right next to the superproject on the server. Thus, we have: superproject url = server:/public/super submodoule url = server:/public/sub1 However, in the checked out superproject's .git/config [remote "origin"] url = server:/public/super/ and for similar reasons, the submodule has its URL recorded in .gitmodules as [submodule "sub"] path = submodule1 url = ../sub1/ resolve_relative_url gets the submodule's recorded url as $1, which the caller retrieved from .gitmodules, and retrieves the superprojects origin from .git/config. So in this case resolve_relative_url has that: url = ../sub1/ remoteurl = server:/public/super/ So, without any patch, resolve_relative_url computes the submodule's URL as: server:/public/super/sub1/ rather than server:/public/sub1 In summary, it is essential that resolve_relative_url strip the trailing / from the superproject's url before starting, and beneficial if it assures that the result does not contain a trailing / as the submodule may itself also be a superproject.

submodule: process conflicting submodules only once During a merge module_list returns conflicting submodules several times (stage 1,2,3) which caused the submodules to be used multiple times in git submodule init, sync, update and status command. There are 5 callers of module_list; they all read (mode, sha1, stage, path) tuple, and most of them care only about path. As a first level approximation, it should be Ok (in the sense that it does not make things worse than it currently is) to filter the duplicate paths from module_list output, but some callers should change their behaviour when the merge in the superproject still has conflicts. Notice the higher-stage entries, and emit only one record from module_list, but while doing so, mark the entry with "U" (not [0-3]) in the $stage field and null out the SHA-1 part, as the object name for the lowest stage does not give any useful information to the caller, and this way any caller that uses the object name would hopefully barf. Then update the codepaths for each subcommands this way: - "update" should not touch the submodule repository, because we do not know what commit should be checked out yet. - "status" reports the conflicting submodules as 'U000...000' and does not recurse into them (we might later want to make it recurse). - The command called by "foreach" may want to do whatever it wants to do by noticing the merged status in the superproject itself, so feed the path to it from module_list as before, but only once per submodule. - "init" and "sync" are unlikely things to do while the superproject is still not merged, but as long as a submodule is there in $path, there is no point skipping it. It might however want to take the merged status of .gitmodules into account, but that is outside of the scope of this topic.

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.

submodules: refactor computation of relative gitdir path In module_clone() the rel_gitdir variable was computed differently when "git rev-parse --git-dir" returned a relative path than when it returned an absolute path. This is not optimal, as different code paths are used depending on the return value of that command. Fix that by reusing the differing path components computed for setting the core.worktree config setting, which leaves a single code path for setting both instead of having three and makes the code much shorter. This also fixes the bug that in the computation of how many directories have to be traversed up to hit the root directory of the submodule the name of the submodule was used where the path should have been used. This lead to problems after renaming submodules into another directory level. Even though the "(cd $somewhere && pwd)" approach breaks the flexibility of symlinks, that is no issue here as we have to have one relative path pointing from the work tree to the gitdir and another pointing back, which will never work anyway when a symlink along one of those paths is changed because the directory it points to was moved. Also add a test moving a submodule into a deeper directory to catch any future breakage here and to document what has to be done when a submodule needs to be moved until git mv learns to do that. Simply moving it to the new location doesn't work, as the core.worktree and possibly the gitfile setting too will be wrong. So it has to be removed from filesystem and index, then the new location has to be added into the index and the .gitmodules file has to be updated. After that a git submodule update will check out the submodule at the new location. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git-submodule - make "submodule add" more strict, and document it This change makes "submodule add" much more strict in the arguments it takes, and is intended to address confusion as recently noted on the git-list. With this change, the required syntax is: $ git submodule add URL path Specifically, this eliminates the form $ git submodule add URL which was confused by more than one person as $ git submodule add path With this patch, the URL locating the submodule's origin repository can be either an absolute URL, or (if it begins with ./ or ../) can express the submodule's repository location relative to the superproject's origin. This patch also eliminates a third form of URL, which was relative to the superproject's top-level directory (not its repository). Any URL that was neither absolute nor matched ./*|../* was assumed to point to a subdirectory of the superproject as the location of the submodule's origin repository. This URL form was confusing and does not seem to correspond to an important use-case. Specifically, no-one has identified the need to clone from a repository already in the superproject's tree, but if this is needed it is easily done using an absolute URL: $(pwd)/relative-path. So, no functionality is lost with this patch. (t6008-rev-list-submodule.sh did rely upon this relative URL, fixed by using $(pwd).) Following this change, there are exactly four variants of submodule-add, as both arguments have two flavors: URL can be absolute, or can begin with ./|../ and thus names the submodule's origin relative to the superproject's origin. Note: With this patch, "submodule add" discerns an absolute URL as matching /*|*:*: e.g., URL begins with /, or it contains a :. This works for all valid URLs, an absolute path in POSIX, as well as an absolute path on Windows). path can either already exist as a valid git repo, or will be cloned from the given URL. The first form here eases creation of a new submodule in an existing superproject as the submodule can be added and tested in-tree before pushing to the public repository. However, the more usual form is the second, where the repo is cloned from the given URL. This specifically addresses the issue of $ git submodule add a/b/c attempting to clone from a repository at "a/b/c" to create a new module in "c". This also simplifies description of "relative URL" as there is now exactly *one* form: a URL relative to the parent's origin repo.

git-submodule - make "submodule add" more strict, and document it This change makes "submodule add" much more strict in the arguments it takes, and is intended to address confusion as recently noted on the git-list. With this change, the required syntax is: $ git submodule add URL path Specifically, this eliminates the form $ git submodule add URL which was confused by more than one person as $ git submodule add path With this patch, the URL locating the submodule's origin repository can be either an absolute URL, or (if it begins with ./ or ../) can express the submodule's repository location relative to the superproject's origin. This patch also eliminates a third form of URL, which was relative to the superproject's top-level directory (not its repository). Any URL that was neither absolute nor matched ./*|../* was assumed to point to a subdirectory of the superproject as the location of the submodule's origin repository. This URL form was confusing and does not seem to correspond to an important use-case. Specifically, no-one has identified the need to clone from a repository already in the superproject's tree, but if this is needed it is easily done using an absolute URL: $(pwd)/relative-path. So, no functionality is lost with this patch. (t6008-rev-list-submodule.sh did rely upon this relative URL, fixed by using $(pwd).) Following this change, there are exactly four variants of submodule-add, as both arguments have two flavors: URL can be absolute, or can begin with ./|../ and thus names the submodule's origin relative to the superproject's origin. Note: With this patch, "submodule add" discerns an absolute URL as matching /*|*:*: e.g., URL begins with /, or it contains a :. This works for all valid URLs, an absolute path in POSIX, as well as an absolute path on Windows). path can either already exist as a valid git repo, or will be cloned from the given URL. The first form here eases creation of a new submodule in an existing superproject as the submodule can be added and tested in-tree before pushing to the public repository. However, the more usual form is the second, where the repo is cloned from the given URL. This specifically addresses the issue of $ git submodule add a/b/c attempting to clone from a repository at "a/b/c" to create a new module in "c". This also simplifies description of "relative URL" as there is now exactly *one* form: a URL relative to the parent's origin repo.

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.

When I do: git submodule add <url> hlagh git-submodule will get as far as checking out the remote repository into hlagh, but it'll die right afterwards when it fails to add the new path: The following paths are ignored by one of your .gitignore files: hlagh Use -f if you really want to add them. fatal: no files added Failed to add submodule 'hlagh' Currently there's no way to add a submodule in this situation other than to remove the ignored path from the .gitignore while I'm at it. That's silly, when you run `git submodule add' you're explicitly saying that you want to add something *new* to the repository. Instead it should just add the path with `git add --force'. Initially I implemented this by adding new -f and --force options to `git submodule add'. But if the --force option isn't supplied it'll get as far as cloning `hlagh', but won't add it. So the first thing the user has to do is to remove `hlagh' and then try again with the --force option. That sucks, it should just add the path to begin with. I can't think of any usecase where you've gone through the trouble of typing out `git submodule add ..', but wish to be overriden by a `gitignore'. The submodule semantics should be more like `git init', not `git add'. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.

git-submodule foreach: Add $toplevel variable Add a $toplevel variable accessible to `git submodule foreach`, it contains the absolute path of the top level directory (where .gitmodules is). This makes it possible to e.g. read data in .gitmodules from within foreach commands. I'm using this to configure the branch names I want to track for each submodule: git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' For a little history: This patch is borne out of my continuing fight of trying to have Git track the branches of submodules, not just their commits. Obviously that's not how they work (they only track commits), but I'm just interested in being able to do: git submodule foreach 'git pull' Of course that won't work because the submodule is in a disconnected head, so I first have to connect it, but connect it *to what*. For a while I was happy with this because as fate had it, it just so happened to do what I meant: git submodule foreach 'git checkout $(git describe --all --always) && git pull' But then that broke down, if there's a tag and a branch the tag will win out, and I can't git pull a branch: $ git branch -a * master remotes/origin/HEAD -> origin/master remotes/origin/master $ git tag -l release-0.0.6 $ git describe --always --all release-0.0.6 So I figured that I might as well start tracking the branches I want in .gitmodules itself: [submodule "yaml-mode"] path = yaml-mode url = git://github.com/yoshiki/yaml-mode.git branch = master So now I can just do (as stated above): git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' Maybe there's a less painful way to do *that* (I'd love to hear about it). But regardless of that I think it's a good idea to be able to know what the top-level is from git submodule foreach.

git-submodule.sh: preserve stdin for the command spawned by foreach The user-supplied command spawned by 'submodule foreach' loses its connection to the original standard input. Instead, it is connected to the output of a pipe within the git-submodule script. The user-supplied command supplied to 'submodule foreach' is spawned within a while loop which is being piped into. Due to the way shells implement piping output to a while loop, a subshell is created with its standard input attached to the output of the pipe. This results in all of the commands executed within the while loop to have their stdins modified in the same way, including the user-supplied command. This can cause a problem if the command requires reading from stdin or if it changes its behavior based on whether stdin is a tty or not. For example, this problem was noticed when trying to execute the following: git submodule foreach git shortlog --since=two.weeks.ago which printed a message about entering the first submodule and produced no further output and exited with a status of zero. In this case, shortlog detected that it was not connected to a tty, and since no revision was supplied as an argument, it attempted to read the list of revisions from standard input. Instead, it slurped up the list of submodules that was being piped to the enclosing while loop and caused that loop to end early without processing the remaining submodules. Work around this behavior by saving the original standard input file descriptor before the while loop, and restoring it when spawning the user-supplied command. This fixes the tests in t7407.

submodule update: add --remote for submodule's upstream changes The current `update` command incorporates the superproject's gitlinked SHA-1 ($sha1) into the submodule HEAD ($subsha1). Depending on the options you use, it may checkout $sha1, rebase the $subsha1 onto $sha1, or merge $sha1 into $subsha1. This helps you keep up with changes in the upstream superproject. However, it's also useful to stay up to date with changes in the upstream subproject. Previous workflows for incorporating such changes include the ungainly: $ git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' With this patch, all of the useful functionality for incorporating superproject changes can be reused to incorporate upstream subproject updates. When you specify --remote, the target $sha1 is replaced with a $sha1 of the submodule's origin/master tracking branch. If you want to merge a different tracking branch, you can configure the `submodule.<name>.branch` option in `.gitmodules`. You can override the `.gitmodules` configuration setting for a particular superproject by configuring the option in that superproject's default configuration (using the usual configuration hierarchy, e.g. `.git/config`, `~/.gitconfig`, etc.). Previous use of submodule.<name>.branch ======================================= Because we're adding a new configuration option, it's a good idea to check if anyone else is already using the option. The foreach-pull example above was described by Ævar in commit f030c96d8643fa0a1a9b2bd9c2f36a77721fb61f Author: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Date: Fri May 21 16:10:10 2010 +0000 git-submodule foreach: Add $toplevel variable Gerrit uses the same interpretation for the setting, but because Gerrit has direct access to the subproject repositories, it updates the superproject repositories automatically when a subproject changes. Gerrit also accepts the special value '.', which it expands into the superproject's branch name. Although the --remote functionality is using `submodule.<name>.branch` slightly differently, the effect is the same. The foreach-pull example uses the option to record the name of the local branch to checkout before pulls. The tracking branch to be pulled is recorded in `.git/modules/<name>/config`, which was initialized by the module clone during `submodule add` or `submodule init`. Because the branch name stored in `submodule.<name>.branch` was likely the same as the branch name used during the initial `submodule add`, the same branch will be pulled in each workflow. Implementation details ====================== In order to ensure a current tracking branch state, `update --remote` fetches the submodule's remote repository before calculating the SHA-1. However, I didn't change the logic guarding the existing fetch: if test -z "$nofetch" then # Run fetch only if $sha1 isn't present or it # is not reachable from a ref. (clear_local_git_env; cd "$path" && ( (rev=$(git rev-list -n 1 $sha1 --not --all 2>/dev/null) && test -z "$rev") || git-fetch)) || die "$(eval_gettext "Unable to fetch in submodule path '\$path'")" fi There will not be a double-fetch, because the new $sha1 determined after the `--remote` triggered fetch should always exist in the repository. If it doesn't, it's because some racy process removed it from the submodule's repository and we *should* be re-fetching. Signed-off-by: W.

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.

Then update the codepaths for each subcommands this way: - "update" should not touch the submodule repository, because we do not know what commit should be checked out yet. - "status" reports the conflicting submodules as 'U000...000' and does not recurse into them (we might later want to make it recurse). - The command called by "foreach" may want to do whatever it wants to do by noticing the merged status in the superproject itself, so feed the path to it from module_list as before, but only once per submodule. - "init" and "sync" are unlikely things to do while the superproject is still not merged, but as long as a submodule is there in $path, there is no point skipping it.

submodule update: add --remote for submodule's upstream changes The current `update` command incorporates the superproject's gitlinked SHA-1 ($sha1) into the submodule HEAD ($subsha1). Depending on the options you use, it may checkout $sha1, rebase the $subsha1 onto $sha1, or merge $sha1 into $subsha1. This helps you keep up with changes in the upstream superproject. However, it's also useful to stay up to date with changes in the upstream subproject. Previous workflows for incorporating such changes include the ungainly: $ git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' With this patch, all of the useful functionality for incorporating superproject changes can be reused to incorporate upstream subproject updates. When you specify --remote, the target $sha1 is replaced with a $sha1 of the submodule's origin/master tracking branch. If you want to merge a different tracking branch, you can configure the `submodule.<name>.branch` option in `.gitmodules`. You can override the `.gitmodules` configuration setting for a particular superproject by configuring the option in that superproject's default configuration (using the usual configuration hierarchy, e.g. `.git/config`, `~/.gitconfig`, etc.).

git-submodule summary: show commit summary This patch does the hard work to show submodule commit summary. For a modified submodule, a series of commits will be shown with the following command: git log --pretty='format:%m %s' \ --first-parent sha1_src...sha1_dst where the sha1_src is from the given super project commit and the sha1_dst is from the index or working tree (switched by --cached). For a deleted, added, or typechanged (blob<->submodule) submodule, only one single newest commit from the existing end (for example, src end for submodule deleted or type changed from submodule to blob) will be shown. If the src/dst sha1 for a submodule is missing in the submodule directory, a warning will be issued except in two cases where the submodule directory is deleted (type 'D') or typechanged to blob (one case of type 'T'). In the title line for a submodule, the src/dst sha1 and the number of commits (--first-parent) between the two commits will be shown. The following example demonstrates most cases. Example: commit summary for modified submodules sm1-sm5. -------------------------------------------- $ git submodule summary * sm1 354cd45...3f751e5 (4): < one line message for C < one line message for B > one line message for D > one line message for E * sm2 5c8bfb5...000000 (3): < one line message for F * sm3 354cd45...3f751e5: Warn: sm3 doesn't contain commit 354cd45 * sm4 354cd34(submodule)-> 235efa(blob) (1): < one line message for G * sm5 354cd34(blob)-> 235efa(submodule) (5): > one line message for H -------------------------------------------- Signed-off-by: Ping Yin <pkufranky@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.

submodule: process conflicting submodules only once During a merge module_list returns conflicting submodules several times (stage 1,2,3) which caused the submodules to be used multiple times in git submodule init, sync, update and status command. There are 5 callers of module_list; they all read (mode, sha1, stage, path) tuple, and most of them care only about path. As a first level approximation, it should be Ok (in the sense that it does not make things worse than it currently is) to filter the duplicate paths from module_list output, but some callers should change their behaviour when the merge in the superproject still has conflicts. Notice the higher-stage entries, and emit only one record from module_list, but while doing so, mark the entry with "U" (not [0-3]) in the $stage field and null out the SHA-1 part, as the object name for the lowest stage does not give any useful information to the caller, and this way any caller that uses the object name would hopefully barf. Then update the codepaths for each subcommands this way: - "update" should not touch the submodule repository, because we do not know what commit should be checked out yet. - "status" reports the conflicting submodules as 'U000...000' and does not recurse into them (we might later want to make it recurse). - The command called by "foreach" may want to do whatever it wants to do by noticing the merged status in the superproject itself, so feed the path to it from module_list as before, but only once per submodule. - "init" and "sync" are unlikely things to do while the superproject is still not merged, but as long as a submodule is there in $path, there is no point skipping it. It might however want to take the merged status of .gitmodules into account, but that is outside of the scope of this topic.

git-submodule.sh: Don't use $path variable in eval_gettext string The eval_gettext (and eval_gettextln) i18n shell functions call git-sh-i18n--envsubst to process the variable references in the string parameter. Unfortunately, environment variables are case insensitive on windows, which leads to failure on cygwin when eval_gettext exports $path. Commit df599e9 (Windows: teach getenv to do a case-sensitive search, 06-06-2011) attempts to solve this problem on MinGW by overriding the system getenv() function to allow git-sh-i18n--envsubst to read $path rather than $PATH from the environment. However, this commit does not address cygwin at all and, furthermore, does not fix all problems on MinGW. In particular, when executing test #38 in t7400-submodule-basic.sh, an 'git-sh-i18n-envsubst.exe - Unable To Locate Component' dialog pops up saying that the application "failed to start because libiconv2.dll was not found." After studying the voluminous trace output from the process monitor, it is clear that the system is attempting to use $path, rather than $PATH, to search for the DLL file. (Note that, after dismissing the dialog, the test passes anyway!) As an alternative, we finesse the problem by renaming the $path variable to $sm_path (submodule path). This fixes the problem on MinGW along with all test failures on cygwin (t7400.{7,32,34}, t7406.3 and t7407.{2,6}). We note that the foreach subcommand provides $path to user scripts (ie it is part of the API), so we can't simply rename it to $sm_path.
