2017-09-27t7406: submodule.<name>.update command must not be run from .gitmodulesLibravatar Stefan Beller1-0/+8
submodule.<name>.update can be assigned an arbitrary command via setting it to "!command". When this command is found in the regular config, Git ought to just run that command instead of other update mechanisms. However if that command is just found in the .gitmodules file, it is potentially untrusted, which is why we do not run it. Add a test confirming the behavior.

2017-05-11tests: fix tests broken under GETTEXT_POISON=YesPleaseLibravatar Ævar Arnfjörð Bjarmason1-1/+1
The GETTEXT_POISON=YesPlease compile-time testing option added in my bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly translator", 2011-02-22) has been slowly bitrotting as strings have been marked for translation, and new tests have been added without running it. I brought this up on the list ("[BUG] test suite broken with GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at all anymore. At least one person occasionally uses it, and Lars Schneider offered to change one of the the Travis builds to run in this mode, so fix up the failing ones. My test setup runs most of the tests, with the notable exception of skipping all the p4 tests, so it's possible that there's still some lurking regressions I haven't fixed. 1. <CACBZZX62+acvi1dpkknadTL827mtCm_QesGSZ=6+UnyeMpg8+Q@mail.gmail.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

There are three issues with the test: * The syntax of the here-doc was wrong, such that the entire test was sucked into the here-doc, which is why the test succeeded. * The variable $submodulesha1 was not expanded as it was inside a quoted here text. We do not want to quote EOF marker for this. * The redirection from the git command to the output file for comparison was wrong as the -C operator from git doesn't apply to the redirect path.

The user can specify a custom update method that is run when "submodule update" updates an already checked out submodule. This was ignored when checking the submodule out for the first time and we instead always just checked out the commit that is bound to the path in the superproject's index. * sb/submodule-update-initial-runs-custom-script: submodule update: run custom update script for initial populating as well
2017-01-26submodule update: run custom update script for initial populating as wellLibravatar Stefan Beller1-0/+12
In 1b4735d9f3 (submodule: no [--merge|--rebase] when newly cloned, 2011-02-17), all actions were defaulted to checkout for populating a submodule initially, because merging or rebasing makes no sense in that situation. Other commands however do make sense, such as the custom command that was added later (6cb5728c43, submodule update: allow custom command to update submodule working tree, 2013-07-03). I am unsure about the "none" command, as I can see an initial checkout there as a useful thing. On the other hand going strictly by our own documentation, we should do nothing in case of "none" as well, because the user asked for it.

2017-01-12submodule update --init: display correct path from submoduleLibravatar Stefan Beller1-0/+17
In the submodule helper we did not correctly handled the display path for initializing submodules when both the submodule is inside a subdirectory as well as the command being invoked from a subdirectory (as viewed from the superproject). This was broken in 3604242f080, which was written at a time where there was no super-prefix available, so we abused the --prefix option for the same purpose and could get only one case right (the call from within a subdirectory, not the submodule being in a subdirectory).

2016-08-10t7406: fix breakage on OSXLibravatar Stefan Beller1-1/+1
On OSX `wc` prefixes the output of numbers with whitespace, such that the `commit_count` would be "SP <NUMBER>". When using that in git submodule update --init --depth=$commit_count the depth would be empty and the number is interpreted as the pathspec. Fix this by not using `wc` and rather instruct rev-list to count. Another way to fix this is to remove the `=` sign after the `--depth` argument as then we are allowed to have more than just one whitespace between `--depth` and the actual number. Prefer the solution of rev-list counting as that is expected to be slightly faster and more self-contained within Git.

2016-08-03submodule update: allow '.' for branch valueLibravatar Stefan Beller1-1/+34
Gerrit has a "superproject subscription" feature[1], that triggers a commit in a superproject that is subscribed to its submodules. Conceptually this Gerrit feature can be done on the client side with Git via (except for raciness, error handling etc): while [ true ]; do git -C <superproject> submodule update --remote --force git -C <superproject> commit -a -m "Update submodules" git -C <superproject> push done for each branch in the superproject. To ease the configuration in Gerrit a special value of "." has been introduced for the submodule.<name>.branch to mean the same branch as the superproject[2], such that you can create a new branch on both superproject and the submodule and this feature continues to work on that new branch. Now we find projects in the wild with such a .gitmodules file. The .gitmodules used in these Gerrit projects do not conform to Gits understanding of how .gitmodules should look like. This teaches Git to deal gracefully with this syntax as well. The redefinition of "." does no harm to existing projects unaware of this change, as "." is an invalid branch name in Git, so we do not expect such projects to exist.

2016-06-17tests: use test_i18n* functions to suppress false positivesLibravatar Vasco Almeida1-5/+5
The test functions test_i18ncmp and test_i18ngrep pretend success if run under GETTEXT_POISON. By using those functions to test output which is correctly marked as translatable, enables one to detect if the strings newly marked for translation are from plumbing output. If they are indeed from plumbing, the test would fail, and the string should be unmarked, since it is not seen by users. Thus, it is productive to not have false positives when running the test under GETTEXT_POISON. This commit replaces normal test functions by their i18n aware variants in use-cases know to be correctly marked for translation, suppressing false positives.

Reroute the output of stdout to stderr as it is just informative messages, not to be consumed by machines. This should not regress any scripts that try to parse the current output, as the output is already internationalized and therefore unstable. We want to init submodules from the helper for `submodule update` in a later patch and the stdout output of said helper is consumed by the parts of `submodule update` which are still written in shell.

2016-03-30submodule update: test recursive path reporting from subdirectoryLibravatar Stefan Beller1-0/+20
This patch is just a test and fixes no bug as there is currently no bug in the path handling of `submodule update`. In `submodule update` we make a call to `submodule--helper list --prefix "$wt_prefix"` which looks a bit brittle and likely to introduce a bug for the path handling. It is not a bug as the prefix is ignored inside the submodule helper for now. If this test breaks eventually, we want to make sure the `wt_prefix` is passed correctly into recursive submodules.

The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character.

2014-02-24submodule: explicit local branch creation in module_cloneLibravatar W. Trevor King1-1/+38
The previous code only checked out branches in cmd_add. This commit moves the branch-checkout logic into module_clone, where it can be shared by cmd_add and cmd_update. I also update the initial checkout command to use 'reset' to preserve branches setup during module_clone. With this change, folks cloning submodules for the first time via: $ git submodule update ... will get a local branch instead of a detached HEAD, unless they are using the default checkout-mode updates. This is a change from the previous situation where cmd_update always used checkout-mode logic (regardless of the requested update mode) for updates that triggered an initial clone, which always resulted in a detached HEAD. This commit does not change the logic for updates after the initial clone, which will continue to create detached HEADs for checkout-mode updates, and integrate remote work with the local HEAD (detached or not) in other modes. The motivation for the change is that developers doing local work inside the submodule are likely to select a non-checkout-mode for updates so their local work is integrated with upstream work. Developers who are not doing local submodule work stick with checkout-mode updates so any apparently local work is blown away during updates. For example, if upstream rolls back the remote branch or gitlinked commit to an earlier version, the checkout-mode developer wants their old submodule checkout to be rolled back as well, instead of getting a no-op merge/rebase with the rolled-back reference. By using the update mode to distinguish submodule developers from black-box submodule consumers, we can setup local branches for the developers who will want local branches, and stick with detached HEADs for the developers that don't care. Testing ======= In t7406, just-cloned checkouts now update to the gitlinked hash with 'reset', to preserve the local branch for situations where we're not on a detached HEAD. I also added explicit tests to t7406 for HEAD attachement after cloning updates, showing that it depends on their update mode: * Checkout-mode updates get detached HEADs * Everyone else gets a local branch, matching the configured submodule.<name>.branch and defaulting to master. The 'initial-setup' tag makes it easy to reset the superproject to a known state, as several earlier tests commit to submodules and commit the changed gitlinks to the superproject, but don't push the new submodule commits to the upstream subprojects. This makes it impossible to checkout the current super master, because it references submodule commits that don't exist in the upstream subprojects. For a specific example, see the tests that currently generate the 'two_new_submodule_commits' commits. Documentation ============= I updated the docs to describe the 'submodule update' modes in detail. The old documentation did not distinguish between cloning and non-cloning updates and lacked clarity on which operations would lead to detached HEADs, and which would not. The new documentation addresses these issues while updating the docs to reflect the changes introduced by this commit's explicit local branch creation in module_clone. I also add '--checkout' to the usage summary and group the update-mode options into a single set. Signed-off-by: W. Trevor King <wking@tremily.us> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-12-02submodule: do not copy unknown update mode from .gitmodulesLibravatar Junio C Hamano1-0/+15
When submodule.$name.update is given as hint from the upstream in the .gitmodules file, we used to blindly copy it to .git/config, unless there already is a value defined for the submodule. However, there is no reason to expect that the update mode hinted by the upstream is available in the version of Git the user is using, and a really custom "!cmd" prepared by an upstream person running on Linux may not even be available to a user on Windows. It is simply irresponsible to copy the setting blindly and to attempt to use it during a later "submodule update" without validating it first. Just show the suggested value to the diagnostic output, and set the value to 'none' in the configuration, if it is not one of the ones that are known to be supported by this version of Git.

2013-11-11submodule update: remove unnecessary orig_flags variableLibravatar Jens Lehmann1-0/+11
cmd_update() in the submodule script tries to preserve the options given on the command line in the "orig_flags" variable to pass them on into the recursion when the '--recursive' option is given. But this isn't necessary because all the variables set by the options will be seen in the recursion too as that is achieved by executing "eval cmd_update". The same has already been done for cmd_status() in e15bec0ec, so let's clean up cmd_update() likewise. Also add a test to make sure that a submodule name given on the command line is not passed into the recursion (which was the goal of adding the orig_flags variable in 98dbe63db).

2012-12-19submodule update: add --remote for submodule's upstream changesLibravatar W. Trevor King1-0/+31
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.

2012-09-30submodule add: Fail when .git/modules/<name> already exists unless forcedLibravatar Jens Lehmann1-1/+1
When adding a new submodule it can happen that .git/modules/<name> already contains a submodule repo, e.g. when a submodule is removed from the work tree and another submodule is added at the same path. But then the work tree of the submodule will be populated using the existing repository and not the one the user provided, which results in an incorrect work tree. On the other hand the user might reactivate a submodule removed earlier, then reusing that .git directory is the Right Thing to do. As git can't decide what is the case, error out and tell the user she should use either use a different name for the submodule with the "--name" option or can reuse the .git directory for the newly added submodule by providing the --force option (which only makes sense when the upstream matches, so the error message lists all remotes of .git/modules/<name>). In one test in t7406 the --force option had to be added to "git submodule add", as that test re-adds a formerly removed submodule.

Currently, it will only do a checkout if the sha1 registered in the containing repository doesn't match the HEAD of the submodule, regardless of whether the submodule is dirty. As discussed on the mailing list, the '--force' flag is a strong indicator that the state of the submodule is suspect, and should be reset to HEAD.

2012-07-30t7406: fix misleading "rev-parse --max-count=1 HEAD"Libravatar Junio C Hamano1-8/+8
The test happened to use "rev-parse --max-count=1 HEAD" consistently to prepare the expected output and the actual output, so the comparison between them gave us a correct success/failure because both output had irrelevant "--max-count=1" in it. But that is not an excuse to keep it broken. Replace it a more meaningful construct "rev-parse --verify HEAD". Noticed by Daniel Graña while working on his submodule tests.

2012-07-12submodules: don't stumble over symbolic links when cloning recursivelyLibravatar Jens Lehmann1-0/+13
Since 69c3051 (submodules: refactor computation of relative gitdir path) cloning a submodule recursively fails for nested submodules when a symbolic link is part of the path to the work tree of the superproject. This happens when module_clone() tries to find the relative paths between the work tree and the git dir. When a symbolic link in current $PWD points to a directory that is at a different level, then determining the number of "../" needed to traverse to the superproject's work tree leads to a wrong result. As there is no portable way to say "pwd -P", use cd_to_toplevel to remove the link from $PWD, which fixes this problem. A test for this issue has been added to t7406.

2012-03-04submodules: refactor computation of relative gitdir pathLibravatar Jens Lehmann1-0/+17
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>
2012-01-24submodule add: fix breakage when re-adding a deep submoduleLibravatar Jens Lehmann1-0/+8
Since recently a submodule with name <name> has its git directory in the .git/modules/<name> directory of the superproject while the work tree contains a gitfile pointing there. When the same submodule is added on a branch where it wasn't present so far (it is not found in the .gitmodules file), the name is not initialized from the path as it should. This leads to a wrong path entered in the gitfile when the .git/modules/<name> directory is found, as this happily uses the - now empty - name. It then always points only a single directory up, even if we have a path deeper in the directory hierarchy. Fix that by initializing the name of the submodule early in module_clone() if module_name() returned an empty name and add a test to catch that bug.

2011-08-22Move git-dir for submodulesLibravatar Fredrik Gustafsson1-0/+107
Move git-dir for submodules into $GIT_DIR/modules/[name_of_submodule] of the superproject. This is a step towards being able to delete submodule directories without loosing the information from their .git directory as that is now stored outside the submodules work tree. This is done relying on the already existent .git-file functionality. When adding or updating a submodule whose git directory is found under $GIT_DIR/modules/[name_of_submodule], don't clone it again but simply point the .git-file to it and remove the now stale index file from it. The index will be recreated by the following checkout. This patch will not affect already cloned submodules at all. Tests that rely on .git being a directory have been fixed.
