2017-06-23pull: optionally rebase submodules (remote submodule changes only)Libravatar Stefan Beller1-0/+4
Teach pull to optionally update submodules when '--recurse-submodules' is provided. This will teach pull to run 'submodule update --rebase' when the '--recurse-submodules' and '--rebase' flags are given under specific circumstances. On a rebase workflow: ===================== 1. Both sides change the submodule ------------------------------ Let's assume the following history in a submodule: H---I---J---K---L local branch \ M---N---O---P remote branch and the following in the superproject (recorded submodule in parens): A(H)---B(I)---F(K)---G(L) local branch \ C(N)---D(N)---E(P) remote branch In an ideal world this would rebase the submodule and rewrite the submodule pointers that the superproject points at such that the superproject looks like A(H)---B(I) F(K')---G(L') rebased branch \ / C(N)---D(N)---E(P) remote branch and the submodule as: J---K---L (old dangeling tip) / H---I J'---K'---L' rebased branch \ / M---N---O---P remote branch And if a conflict arises in the submodule the superproject rebase would stop at that commit at which the submodule conflict occurs. Currently a "pull --rebase" in the superproject produces a merge conflict as the submodule pointer changes are conflicting and cannot be resolved. 2. Local submodule changes only ----------------------- Assuming histories as above, except that the remote branch would not contain submodule changes, then a result as A(H)---B(I) F(K)---G(L) rebased branch \ / C(I)---D(I)---E(I) remote branch is desire-able. This is what currently happens in rebase. If the recursive flag is given, the ideal git would produce a superproject as: A(H)---B(I) F(K')---G(L') rebased branch (incl. sub rebase!) \ / C(I)---D(I)---E(I) remote branch and the submodule as: J---K---L (old dangeling tip) / H---I J'---K'---L' locally rebased branch \ / M---N---O---P advanced branch This patch doesn't address this issue, however a test is added that this fails up front. 3. Remote submodule changes only ---------------------- Assuming histories as in (1) except that the local superproject branch would not have touched the submodule the rebase already works out in the superproject with no conflicts: A(H)---B(I) F(P)---G(P) rebased branch (no sub changes) \ / C(N)---D(N)---E(P) remote branch The recurse flag as presented in this patch would additionally update the submodule as: H---I J'---K'---L' rebased branch \ / M---N---O---P remote branch As neither J, K, L nor J', K', L' are referred to from the superproject, no rewriting of the superproject commits is required. Conclusion for 'pull --rebase --recursive' ----------------------------------------- If there are no local superproject changes it is sufficient to call "submodule update --rebase" as this produces the desired results. In case of conflicts, the behavior is the same as in 'submodule update --recursive' which is assumed to be sane. This patch implements (3) only. On a merge workflow: ==================== We'll start off with the same underlying DAG as in (1) in the rebase workflow. So in an ideal world a 'pull --merge --recursive' would produce this: H---I---J---K---L----X \ / M---N---O---P with X as the new merge-commit in the submodule and the superproject as: A(H)---B(I)---F(K)---G(L)---Y(X) \ / C(N)---D(N)---E(P) However modifying the submodules on the fly is not supported in git-merge such that Y(X) is not easy to produce in a single patch. In fact git-merge doesn't know about submodules at all. However when at least one side does not contain commits touching the submodule at all, then we do not need to perform the merge for the submodule but a fast-forward can be done via checking out either L or P in the submodule. This strategy is implemented in 68d03e4a6e (Implement automatic fast-forward merge for submodules, 2010-07-07) already, so to align with the rebase behavior we need to also update the worktree of the submodule.

2017-05-30reset/checkout/read-tree: unify config callback for submodule recursionLibravatar Stefan Beller1-1/+5
The callback function is essentially duplicated 3 times. Remove all of them and offer a new callback function, that lives in submodule.c By putting the callback function there, we no longer need the function 'set_config_update_recurse_submodules', nor duplicate the global variable in each builtin as well as submodule.c In the three builtins we have different 2 ways how to load the .gitmodules and config file, which are slightly different. git-checkout has to load the submodule config all the time due to 23b4c7bcc5 (checkout: Use submodule.*.ignore settings from .git/config and .gitmodules, 2010-08-28) git-reset and git-read-tree do not respect these diff settings, so loading the submodule configuration is optional.

Since (ae8d08242 pathspec: pass directory indicator to match_pathspec_item()) the path matching logic has been able to cope with submodules without needing to strip off a trailing slash if a path refers to a submodule. Since the stripping the trailing slash is no longer necessary, remove the PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag. In addition, factor out the logic which dies if a path decends into a submodule so that it can still be used as a check after a pathspec struct has been initialized.

Currently 'git add' is the only command which dies when launched from an unpopulated submodule (the place-holder directory for a submodule which hasn't been checked out). This is triggered implicitly by passing the PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag to 'parse_pathspec()'. Instead make this desire more explicit by creating a function 'die_in_unpopulated_submodule()' which dies if the provided 'prefix' has a leading path component which matches a submodule in the the index.

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.

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.

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.

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.

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.

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).

2016-04-28submodule--helper: move config-sanitizing to submodule.cLibravatar Jeff King1-0/+16
These functions should be used by any code which spawns a submodule process, which may happen in submodule.c (e.g., for spawning fetch). Let's move them there and make them public so that submodule--helper can continue to use them. Since they're now public, let's also provide a basic overview of their intended use.

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`.

2016-03-01fetching submodules: respect `submodule.fetchJobs` config optionLibravatar Stefan Beller1-0/+2
This allows to configure fetching and updating in parallel without having the command line option. This moved the responsibility to determine how many parallel processes to start from builtin/fetch to submodule.c as we need a way to communicate "The user did not specify the number of parallel processes in the command line options" in the builtin fetch. The submodule code takes care of the precedence (CLI > config > default).

2016-03-01submodule-config: keep update strategy aroundLibravatar Stefan Beller1-0/+16
Currently submodule.<name>.update is only handled by git-submodule.sh. C code will start to need to make use of that value as more of the functionality of git-submodule.sh moves into library code in C. Add the update field to 'struct submodule' and populate it so it can be read as sm->update or from sm->update_command.
