transport: add protocol policy config option Previously the `GIT_ALLOW_PROTOCOL` environment variable was used to specify a whitelist of protocols to be used in clone/fetch/push commands. This patch introduces new configuration options for more fine-grained control for allowing/disallowing protocols. This also has the added benefit of allowing easier construction of a protocol whitelist on systems where setting an environment variable is non-trivial. Now users can specify a policy to be used for each type of protocol via the 'protocol.<name>.allow' config option. A default policy for all unconfigured protocols can be set with the 'protocol.allow' config option. If no user configured default is made git will allow known-safe protocols (http, https, git, ssh, file), disallow known-dangerous protocols (ext), and have a default policy of `user` for all other protocols. The supported policies are `always`, `never`, and `user`. The `user` policy can be used to configure a protocol to be usable when explicitly used by a user, while disallowing it for commands which run clone/fetch/push commands without direct user intervention (e.g. recursive initialization of submodules). Commands which can potentially clone/fetch/push from untrusted repositories without user intervention can export `GIT_PROTOCOL_FROM_USER` with a value of '0' to prevent protocols configured to the `user` policy from being used. Fix remote-ext tests to use the new config to allow the ext protocol to be tested.

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.

clone: pass --progress decision to recursive submodules When cloning with "--recursive", we'd generally expect submodules to show progress reports if the main clone did, too. In older versions of git, this mostly worked out of the box. Since we show progress by default when stderr is a tty, and since the child clones inherit the parent stderr, then both processes would come to the same decision by default. If the parent clone was asked for "--quiet", we passed down "--quiet" to the child. However, if stderr was not a tty and the user specified "--progress", we did not propagate this to the child. That's a minor bug, but things got much worse when we switched recently to submodule--helper's update_clone command. With that change, the stderr of the child clones are always connected to a pipe, and we never output progress at all. This patch teaches git-submodule and git-submodule--helper how to pass down an explicit "--progress" flag when cloning. The clone command then decides to propagate that flag based on the cloning decision made earlier (which takes into account isatty(2) of the parent process, existing --progress or --quiet flags, etc). Since the child processes always run without a tty on stderr, we don't have to worry about passing an explicit "--no-progress"; it's the default for them. This fixes the recent loss of progress during recursive clones. And as a bonus, it makes: git clone --recursive --progress ... 2>&1 | cat work by triggering progress explicitly in the children.

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.

submodule: support reading .gitmodules when it's not in the working tree When the .gitmodules file is not available in the working tree, try using the content from the index and from the current branch. This covers the case when the file is part of the repository but for some reason it is not checked out, for example because of a sparse checkout. This makes it possible to use at least the 'git submodule' commands which *read* the gitmodules configuration file without fully populating the working tree. Writing to .gitmodules will still require that the file is checked out, so check for that before calling config_set_in_gitmodules_file_gently. Add a similar check also in git-submodule.sh::cmd_add() to anticipate the eventual failure of the "git submodule add" command when .gitmodules is not safely writeable; this prevents the command from leaving the repository in a spurious state (e.g. the submodule repository was cloned but .gitmodules was not updated because config_set_in_gitmodules_file_gently failed). Moreover, since config_from_gitmodules() now accesses the global object store, it is necessary to protect all code paths which call the function against concurrent access to the global object store. Currently this only happens in builtin/grep.c::grep_submodules(), so call grep_read_lock() before invoking code involving config_from_gitmodules(). Finally, add t7418-submodule-sparse-gitmodules.sh to verify that reading from .gitmodules succeeds and that writing to it fails when the file is not checked out. NOTE: there is one rare case where this new feature does not work properly yet: nested submodules without .gitmodules in their working tree. This has been documented with a warning and a test_expect_failure item in t7814, and in this case the current behavior is not altered: no config is read.

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.

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.

add: warn when adding an embedded repository It's an easy mistake to add a repository inside another repository, like: git clone $url git add . The resulting entry is a gitlink, but there's no matching .gitmodules entry. Trying to use "submodule init" (or clone with --recursive) doesn't do anything useful. Prior to v2.13, such an entry caused git-submodule to barf entirely. In v2.13, the entry is considered "inactive" and quietly ignored. Either way, no clone of your repository can do anything useful with the gitlink without the user manually adding the submodule config. In most cases, the user probably meant to either add a real submodule, or they forgot to put the embedded repository in their .gitignore file. Let's issue a warning when we see this case. There are a few things to note: - the warning will go in the git-add porcelain; anybody wanting to do low-level manipulation of the index is welcome to create whatever funny states they want. - we detect the case by looking for a newly added gitlink; updates via "git add submodule" are perfectly reasonable, and this avoids us having to investigate .gitmodules entirely - there's a command-line option to suppress the warning. This is needed for git-submodule itself (which adds the entry before adding any submodule config), but also provides a mechanism for other scripts doing submodule-like things. We could make this a hard error instead of a warning. However, we do add lots of sub-repos in our test suite. It's not _wrong_ to do so. It just creates a state where users may be surprised. Pointing them in the right direction with a gentle hint is probably the best option. There is a config knob that can disable the (long) hint. But I intentionally omitted a config knob to disable the warning entirely. Whether the warning is sensible or not is generally about context, not about the user's preferences. If there's a tool or workflow that adds gitlinks without matching .gitmodules, it should probably be taught about the new command-line option, rather than blanket-disabling the warning.

submodule-config: verify submodule names as paths Submodule "names" come from the untrusted .gitmodules file, but we blindly append them to $GIT_DIR/modules to create our on-disk repo paths. This means you can do bad things by putting "../" into the name (among other things). Let's sanity-check these names to avoid building a path that can be exploited. There are two main decisions: 1. What should the allowed syntax be? It's tempting to reuse verify_path(), since submodule names typically come from in-repo paths. But there are two reasons not to: a. It's technically more strict than what we need, as we really care only about breaking out of the $GIT_DIR/modules/ hierarchy. E.g., having a submodule named "foo/.git" isn't actually dangerous, and it's possible that somebody has manually given such a funny name. b. Since we'll eventually use this checking logic in fsck to prevent downstream repositories, it should be consistent across platforms. Because verify_path() relies on is_dir_sep(), it wouldn't block "foo\..\bar" on a non-Windows machine. 2. Where should we enforce it? These days most of the .gitmodules reads go through submodule-config.c, so I've put it there in the reading step. That should cover all of the C code. We also construct the name for "git submodule add" inside the git-submodule.sh script. This is probably not a big deal for security since the name is coming from the user anyway, but it would be polite to remind them if the name they pick is invalid (and we need to expose the name-checker to the shell anyway for our test scripts). This patch issues a warning when reading .gitmodules and just ignores the related config entry completely. This will generally end up producing a sensible error, as it works the same as a .gitmodules file which is missing a submodule entry (so "submodule update" will barf, but "git clone --recurse-submodules" will print an error but not abort the clone. There is one minor oddity, which is that we print the warning once per malformed config key (since that's how the config subsystem gives us the entries). So in the new test, for example, the user would see three warnings. That's OK, since the intent is that this case should never come up outside of malicious repositories (and then it might even benefit the user to see the message multiple times). Credit for finding this vulnerability and the proof of concept from which the test script was adapted goes to Etienne Stalmans. Signed-off-by: Jeff King <peff@peff.net>

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'.

submodule foreach: fix "<command> --quiet" not being respected Robin reported that git submodule foreach --quiet git pull --quiet origin is not really quiet anymore [1]. "git pull" behaves as if --quiet is not given. This happens because parseopt in submodule--helper will try to parse both --quiet options as if they are foreach's options, not git-pull's. The parsed options are removed from the command line. So when we do pull later, we execute just this git pull origin When calling submodule helper, adding "--" in front of "git pull" will stop parseopt for parsing options that do not really belong to submodule--helper foreach. PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should never see unknown options or something has gone wrong. There are also a couple usage string update while I'm looking at them. While at it, I also add "--" to other subcommands that pass "$@" to submodule--helper. "$@" in these cases are paths and less likely to be --something-like-this. But the point still stands, git-submodule has parsed and classified what are options, what are paths. submodule--helper should never consider paths passed by git-submodule to be options even if they look like one. The test case is also contributed by Robin. [1] it should be quiet before fc1b9243cd (submodule: port submodule subcommand 'foreach' from shell to C, 2018-05-10) because parseopt can't accidentally eat options then. Reported-by: Robin H.

submodule foreach: fix "<command> --quiet" not being respected Robin reported that git submodule foreach --quiet git pull --quiet origin is not really quiet anymore [1]. "git pull" behaves as if --quiet is not given. This happens because parseopt in submodule--helper will try to parse both --quiet options as if they are foreach's options, not git-pull's. The parsed options are removed from the command line. So when we do pull later, we execute just this git pull origin When calling submodule helper, adding "--" in front of "git pull" will stop parseopt for parsing options that do not really belong to submodule--helper foreach. PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should never see unknown options or something has gone wrong. There are also a couple usage string update while I'm looking at them. While at it, I also add "--" to other subcommands that pass "$@" to submodule--helper. "$@" in these cases are paths and less likely to be --something-like-this. But the point still stands, git-submodule has parsed and classified what are options, what are paths. submodule--helper should never consider paths passed by git-submodule to be options even if they look like one. The test case is also contributed by Robin.

clone: pass --progress decision to recursive submodules When cloning with "--recursive", we'd generally expect submodules to show progress reports if the main clone did, too. In older versions of git, this mostly worked out of the box. Since we show progress by default when stderr is a tty, and since the child clones inherit the parent stderr, then both processes would come to the same decision by default. If the parent clone was asked for "--quiet", we passed down "--quiet" to the child. However, if stderr was not a tty and the user specified "--progress", we did not propagate this to the child. That's a minor bug, but things got much worse when we switched recently to submodule--helper's update_clone command. With that change, the stderr of the child clones are always connected to a pipe, and we never output progress at all. This patch teaches git-submodule and git-submodule--helper how to pass down an explicit "--progress" flag when cloning. The clone command then decides to propagate that flag based on the cloning decision made earlier (which takes into account isatty(2) of the parent process, existing --progress or --quiet flags, etc). Since the child processes always run without a tty on stderr, we don't have to worry about passing an explicit "--no-progress"; it's the default for them. This fixes the recent loss of progress during recursive clones. And as a bonus, it makes: git clone --recursive --progress ... 2>&1 | cat work by triggering progress explicitly in the children.

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.

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.

submodule: explain first attempt failure clearly When cloning with --recurse-submodules a superproject with at least one submodule with HEAD pointing to an unborn branch, the clone goes something like this: Cloning into 'test'... <messages about cloning of superproject> Submodule '<name>' (<uri>) registered for path '<submodule path>' Cloning into '<submodule path>'... fatal: Couldn't find remote ref HEAD Unable to fetch in submodule path '<submodule path>' <messages about fetching with SHA-1> From <uri> * branch <hash> -> FETCH_HEAD Submodule path '<submodule path>': checked out '<hash>' In other words, first, a fetch is done with no hash arguments (that is, a fetch of HEAD) resulting in a "Couldn't find remote ref HEAD" error; then, a fetch is done given a hash, which succeeds. The fetch given a hash was added in fb43e31f2b ("submodule: try harder to fetch needed sha1 by direct fetching sha1", 2016-02-24), and the "Unable to fetch..." message was downgraded from a fatal error to a notice in e30d833671 ("git-submodule.sh: try harder to fetch a submodule", 2018-05-16). This commit improves the notice to be clearer that we are retrying the fetch, and that the previous messages (in particular, the fatal errors from fetch) do not necessarily indicate that the whole command fails. In other words: - If the HEAD-fetch succeeds and we then have the commit we want, git-submodule prints no explanation. - If the HEAD-fetch succeeds and we do not have the commit we want, but the hash-fetch succeeds, git-submodule prints no explanation. - If the HEAD-fetch succeeds and we do not have the commit we want, but the hash-fetch fails, git-submodule prints a fatal error. - If the HEAD-fetch fails, fetch prints a fatal error, and git-submodule informs the user that it will retry by fetching specific commits by hash. - If the hash-fetch then succeeds, git-submodule prints no explanation (besides the ones already printed). - If the HEAD-fetch then fails, git-submodule prints a fatal error. It could be said that we should just eliminate the HEAD-fetch altogether, but that changes some behavior (in particular, some refs that were opportunistically updated would no longer be), so I have left that alone for now. There is an analogous situation with the fetching code in fetch_finish() and surrounding functions. For now, I have added a NEEDSWORK.

submodule: port init from shell to C By having the `submodule init` functionality in C, we can reference it easier from other parts in the code in later patches. The code is split up to have one function to initialize one submodule and a calling function that takes care of the rest, such as argument handling and translating the arguments to the paths of the submodules. This is the first submodule subcommand that is fully converted to C except for the usage string, so this is actually removing a call to the `submodule--helper list` function, which is supposed to be used in this transition. Instead we'll make a direct call to `module_list_compute`. An explanation why we need to edit the prefixes in cmd_update in git-submodule.sh in this patch: By having no processing in the shell part, we need to convey the notion of wt_prefix and prefix to the C parts, which former patches punted on and did the processing of displaying path in the shell. `wt_prefix` used to hold the path from the repository root to the current directory, e.g. wt_prefix would be t/ if the user invoked the `git submodule` command in ~/repo/t and ~repo is the GIT_DIR. `prefix` used to hold the relative path from the repository root to the operation, e.g. if you have recursive submodules, the shell script would modify the `prefix` in each recursive step by adding the submodule path. We will pass `wt_prefix` into the C helper via `git -C <dir>` as that will setup git in the directory the user actually called git-submodule.sh from. The `prefix` will be passed in via the `--prefix` option. Having `prefix` and `wt_prefix` relative to the GIT_DIR of the calling superproject is unfortunate with this patch as the C code doesn't know about a possible recursion from a superproject via `submodule update --init --recursive`. To fix this, we change the meaning of `wt_prefix` to point to the current project instead of the superproject and `prefix` to include any relative paths issues in the superproject. That way `prefix` will become the leading part for displaying paths and `wt_prefix` will be empty in recursive calls for now. The new notion of `wt_prefix` and `prefix` still allows us to reconstruct the calling directory in the superproject by just traveling reverse of `prefix`.

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.

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').

submodule foreach: fix "<command> --quiet" not being respected Robin reported that git submodule foreach --quiet git pull --quiet origin is not really quiet anymore [1]. "git pull" behaves as if --quiet is not given. This happens because parseopt in submodule--helper will try to parse both --quiet options as if they are foreach's options, not git-pull's. The parsed options are removed from the command line. So when we do pull later, we execute just this git pull origin When calling submodule helper, adding "--" in front of "git pull" will stop parseopt for parsing options that do not really belong to submodule--helper foreach. PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should never see unknown options or something has gone wrong. There are also a couple usage string update while I'm looking at them. While at it, I also add "--" to other subcommands that pass "$@" to submodule--helper. "$@" in these cases are paths and less likely to be --something-like-this. But the point still stands, git-submodule has parsed and classified what are options, what are paths. submodule--helper should never consider paths passed by git-submodule to be options even if they look like one. The test case is also contributed by Robin. [1] it should be quiet before fc1b9243cd (submodule: port submodule subcommand 'foreach' from shell to C, 2018-05-10) because parseopt can't accidentally eat options then. Reported-by: Robin H.
