2017-04-11push: propagate remote and refspec with --recurse-submodulesLibravatar Brandon Williams1-1/+3
Teach "push --recurse-submodules" to propagate, if given a name as remote, the provided remote and refspec recursively to the pushes performed in the submodules. The push will therefore only succeed if all submodules have a remote with such a name configured. Note that "push --recurse-submodules" with a path or URL as remote will not propagate the remote or refspec and instead use the default remote and refspec configured in the submodule, preserving the current behavior.

2017-03-15submodules: introduce check to see whether to touch a submoduleLibravatar Stefan Beller1-0/+7
In later patches we introduce the --recurse-submodule flag for commands that modify the working directory, e.g. git-checkout. It is potentially expensive to check if a submodule needs an update, because a common theme to interact with submodules is to spawn a child process for each interaction.

"git rm" used to refuse to remove a submodule when it has its own git repository embedded in its working tree.

2016-12-27submodule: rename and add flags to ok_to_remove_submoduleLibravatar Stefan Beller1-1/+5
In different contexts the question "Is it ok to delete a submodule?" may be answered differently. In 293ab15eea (submodule: teach rm to remove submodules unless they contain a git directory, 2012-09-26) a case was made that we can safely ignore ignored untracked files for removal as we explicitely ask for the removal of the submodule. In a later patch we want to remove submodules even when the user doesn't explicitly ask for it (e.g. checking out a tree-ish in which the submodule doesn't exist). In that case we want to be more careful when it comes to deletion of untracked files. As of this patch it is unclear how this will be implemented exactly, so we'll offer flags in which the caller can specify how the different untracked files ought to be handled. As the flags allow the function to not die on an error when spawning a child process, we need to find an appropriate return code for the case when the child process could not be started. As in that case we cannot tell if the submodule is ok to remove, we'd want to return 'false'. As only 0 is understood as false, rename the function to invert the meaning, i.e. the return code of 0 signals the removal of the submodule is fine, and other values can be used to return a more precise answer what went wrong.

2016-12-27submodule.h: add extern keyword to functionsLibravatar Stefan Beller1-25/+30
As the upcoming series will add a lot of functions to the submodule header, let's first make the header consistent to the rest of the project by adding the extern keyword to functions. As per the CodingGuidelines we try to stay below 80 characters per line, so adapt all those functions to stay below 80 characters that are already using more than one line. Those function using just one line are better kept in one line than breaking them up into multiple lines just for the goal of staying below the character limit as it makes grepping for functions easier if they are one liners.

2016-12-12submodule: add absorb-git-dir functionLibravatar Stefan Beller1-0/+4
When a submodule has its git dir inside the working dir, the submodule support for checkout that we plan to add in a later patch will fail. Add functionality to migrate the git directory to be absorbed into the superprojects git directory. The newly added code in this patch is structured such that other areas of Git can also make use of it. The code in the submodule--helper is a mere wrapper and option parser for the function `absorb_git_dir_into_superproject`, that takes care of embedding the submodules git directory into the superprojects git dir. That function makes use of the more abstract function for this use case `relocate_gitdir`, which can be used by e.g. the worktree code eventually to move around a git directory.

2016-11-23push: fix --dry-run to not push submodulesLibravatar Brandon Williams1-1/+3
Teach push to respect the --dry-run option when configured to recursively push submodules 'on-demand'. This is done by passing the --dry-run flag to the child process which performs a push for a submodules when performing a dry-run. In order to preserve good user experience, the additional check for unpushed submodules is skipped during a dry-run when --recurse-submodules=on-demand. The check is skipped because the submodule pushes were performed as dry-runs and this check would always fail as the submodules would still need to be pushed.

An earlier addition of "sanitize_submodule_env" with 14111fc4 (git: submodule honor -c credential.* from command line, 2016-02-29) turned out to be a convoluted no-op; implement what it wanted to do correctly, and stop filtering settings given via "git -c var=val". * jk/submodule-c-credential: submodule: stop sanitizing config options submodule: use prepare_submodule_repo_env consistently submodule--helper: move config-sanitizing to submodule.c submodule: export sanitized GIT_CONFIG_PARAMETERS t5550: break submodule config test into multiple sub-tests t5550: fix typo in $HTTPD_URL
2016-05-06submodule: stop sanitizing config optionsLibravatar Jeff King1-10/+1
The point of having a whitelist of command-line config options to pass to submodules was two-fold: 1. It prevented obvious nonsense like using core.worktree for multiple repos. 2. It could prevent surprise when the user did not mean for the options to leak to the submodules (e.g., http.sslverify=false). For case 1, the answer is mostly "if it hurts, don't do that". For case 2, we can note that any such example has a matching inverted surprise (e.g., a user who meant http.sslverify=true to apply everywhere, but it didn't). So this whitelist is probably not giving us any benefit, and is already creating a hassle as people propose things to put on it. Let's just drop it entirely. Note that we still need to keep a special code path for "prepare the submodule environment", because we still have to take care to pass through $GIT_CONFIG_PARAMETERS (and block the rest of the repo-specific environment variables). We can do this easily from within the submodule shell script, which lets us drop the submodule--helper option entirely (and it's OK to do so because as a "--" program, it is entirely a private implementation detail).

2016-04-16submodule: port init from shell to CLibravatar Stefan Beller1-0/+1
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`.

In a superproject some commands need to interact with submodules. They need to query values from the .gitmodules file either from the worktree of from certain revisions. At the moment this is quite hard since a caller would need to read the .gitmodules file from the history and then parse the values. We want to provide an API for this so we have one place to get values from .gitmodules from any revision (including the worktree). The API is realized as a cache which allows us to lazily read .gitmodules configurations by commit into a runtime cache which can then be used to easily lookup values from it. Currently only the values for path or name are stored but it can be extended for any value needed. It is expected that .gitmodules files do not change often between commits. Thats why we lookup the .gitmodules sha1 from a commit and then either lookup an already parsed configuration or parse and cache an unknown one for each sha1. The cache is lazily build on demand for each requested commit. This cache can be used for all purposes which need knowledge about submodule configurations. Example use cases are: * Recursive submodule checkout needs to lookup a submodule name from its path when a submodule first appears. This needs be done before this configuration exists in the worktree. * The implementation of submodule support for 'git archive' needs to lookup the submodule name to generate the archive when given a revision that is not checked out. * 'git fetch' when given the --recurse-submodules=on-demand option (or configuration) needs to lookup submodule names by path from the database rather than reading from the worktree. For new submodule it needs to lookup the name from its path to allow cloning new submodules into the .git folder so they can be checked out without any network interaction when the user does a checkout of that revision.

2013-08-06rm: delete .gitmodules entry of submodules removed from the work treeLibravatar Jens Lehmann1-0/+1
Currently using "git rm" on a submodule removes the submodule's work tree from that of the superproject and the gitlink from the index. But the submodule's section in .gitmodules is left untouched, which is a leftover of the now removed submodule and might irritate users (as opposed to the setting in .git/config, this must stay as a reminder that the user showed interest in this submodule so it will be repopulated later when an older commit is checked out). Let "git rm" help the user by not only removing the submodule from the work tree but by also removing the "submodule.<submodule name>" section from the .gitmodules file and stage both. This doesn't happen when the "--cached" option is used, as it would modify the work tree. This also silently does nothing when no .gitmodules file is found and only issues a warning when it doesn't have a section for this submodule. This is because the user might just use plain gitlinks without the .gitmodules file or has already removed the section by hand before issuing the "git rm" command (in which case the warning reminds him that rm would have done that for him). Only when .gitmodules is found and contains merge conflicts the rm command will fail and tell the user to resolve the conflict before trying again. Also extend the man page to inform the user about this new feature. While at it promote the submodule sub-section to a chapter as it made not much sense under "REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM". In t7610 three uses of "git rm submod" had to be replaced with "git rm --cached submod" because that test expects .gitmodules and the work tree to stay untouched. Also in t7400 the tests for the remaining settings in the .gitmodules file had to be changed to assert that these settings are missing.

2013-08-06mv: update the path entry in .gitmodules for moved submodulesLibravatar Jens Lehmann1-0/+1
Currently using "git mv" on a submodule moves the submodule's work tree in that of the superproject. But the submodule's path setting in .gitmodules is left untouched, which is now inconsistent with the work tree and makes git commands that rely on the proper path -> name mapping (like status and diff) behave strangely. Let "git mv" help here by not only moving the submodule's work tree but also updating the "submodule.<submodule name>.path" setting from the .gitmodules file and stage both. This doesn't happen when no .gitmodules file is found and only issues a warning when it doesn't have a section for this submodule. This is because the user might just use plain gitlinks without the .gitmodules file or has already updated the path setting by hand before issuing the "git mv" command (in which case the warning reminds him that mv would have done that for him). Only when .gitmodules is found and contains merge conflicts the mv command will fail and tell the user to resolve the conflict before trying again.

2013-07-30submodule.c: add .gitmodules staging helper functionsLibravatar Jens Lehmann1-0/+2
Add the new is_staging_gitmodules_ok() and stage_updated_gitmodules() functions to submodule.c. The first makes it possible for call sites to see if the .gitmodules file did contain any unstaged modifications they would accidentally stage in addition to those they intend to stage themselves. The second function stages all modifications to the .gitmodules file, both will be used by subsequent patches for the mv and rm commands.

2013-07-30mv: move submodules using a gitfileLibravatar Jens Lehmann1-0/+1
When moving a submodule which uses a gitfile to point to the git directory stored in .git/modules/<name> of the superproject two changes must be made to make the submodule work: the .git file and the core.worktree setting must be adjusted to point from work tree to git directory and back. Achieve that by remembering which submodule uses a gitfile by storing the result of read_gitfile() of each submodule. If that is not NULL the new function connect_work_tree_and_git_dir() is called after renaming the submodule's work tree which updates the two settings to the new values. Extend the man page to inform the user about that feature (and while at it change the description to not talk about a script anymore, as mv is a builtin for quite some time now).

2012-11-18submodule: display summary header in boldLibravatar Ramkumar Ramachandra1-1/+1
Currently, 'git diff --submodule' displays output with a bold diff header for non-submodules. So this part is in bold: diff --git a/file1 b/file1 index 30b2f6c..2638038 100644 --- a/file1 +++ b/file1 For submodules, the header looks like this: Submodule submodule1 012b072..248d0fd: Unfortunately, it's easy to miss in the output because it's not bold.

2012-10-29Merge branch 'jl/submodule-rm'Libravatar Jeff King1-0/+2
"git rm submodule" cannot blindly remove a submodule directory as its working tree may have local changes, and worse yet, it may even have its repository embedded in it. Teach it some special cases where it is safe to remove a submodule, specifically, when there is no local changes in the submodule working tree, and its repository is not embedded in its working tree but is elsewhere and uses the gitfile mechanism to point at it. * jl/submodule-rm: submodule: teach rm to remove submodules unless they contain a git directory
