2016-07-22git-submodule: forward exit code of git-submodule--helper more faithfullyLibravatar Johannes Sixt1-11/+11
git-submodule--helper is invoked as the upstream of a pipe in several places. Usually, the failure of a program in this position is not detected by the shell. For this reason, the code inserts a token in the output stream when git-submodule--helper fails that is detected downstream, where the shell script is quit with exit code 1. There happens to be a bug in git-submodule--helper that leads to a segmentation fault. The test suite triggers the crash in several places, all of which are protected by 'test_must_fail'. But due to the inspecific exit code 1, the crash remains undiagnosed. Extend the failure protocol such that git-submodule--helper's exit code is passed downstream (only in the case of failure). This enables the downstream to use it as its own exit code, and 'test_must_fail' to identify the segmentation fault as an unexpected failure. The bug itself is fixed in the next commit.

2016-06-13submodule update: continue when a clone failsLibravatar Stefan Beller1-1/+1
In 15ffb7cde48 (2011-06-13, submodule update: continue when a checkout fails), we reasoned it is ok to continue, when there is not much of a mental burden by the failure. If a recursive submodule fails to clone because a .gitmodules file is broken (e.g. : fatal: No url found for submodule path 'foo/bar' in .gitmodules Failed to recurse into submodule path 'foo', signaled by exit code 128), this is one of the cases where the user is not expected to have much of a burden afterwards, so we can also continue in that case. This means we only want to stop for updating submodules in case of rebase, merge or custom update command failures, which are all signaled with exit code 2.

2016-05-06submodule: stop sanitizing config optionsLibravatar Jeff King1-2/+2
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).

2016-05-05submodule deinit: require '--all' instead of '.' for all submodulesLibravatar Stefan Beller1-3/+12
The discussion in [1] pointed out that '.' is a faulty suggestion as there is a corner case where it fails: > "submodule deinit ." may have "worked" in the sense that you would > have at least one path in your tree and avoided this "nothing > matches" most of the time. It would have still failed with the > exactly same error if run in an empty repository, i.e. > > $ E=/var/tmp/x/empty && rm -fr "$E" && mkdir -p "$E" && cd "$E" > $ git init > $ rungit v2.6.6 submodule deinit . > error: pathspec '.' did not match any file(s) known to git. > Did you forget to 'git add'? > $ >file && git add file > $ rungit v2.6.6 submodule deinit . > $ echo $? > 0 So instead of a pathspec add the '--all' option to deinit all submodules and add a test to check for the corner case of an empty repository. The code only needs to learn about the '--all' option and doesn't require further changes as `git submodule--helper list "$@"` will list all submodules when "$@" is empty.

2016-04-28submodule: export sanitized GIT_CONFIG_PARAMETERSLibravatar Jeff King1-0/+1
Commit 14111fc (git: submodule honor -c credential.* from command line, 2016-02-29) taught git-submodule.sh to save the sanitized value of $GIT_CONFIG_PARAMETERS when clearing the environment for a submodule. However, it failed to export the result, meaning that it had no effect for any sub-programs. We didn't catch this in our initial tests because we checked only the "clone" case, which does not go through the shell script at all.

2016-04-16submodule: port init from shell to CLibravatar Stefan Beller1-45/+3
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`.

Later on we want to automatically call `git submodule init` from other commands, such that the users don't have to initialize the submodule themselves. As these other commands are written in C already, we'd need the init functionality in C, too. The `resolve_relative_url` function is a large part of that init functionality, so start by porting this function to C. To create the tests in t0060, the function `resolve_relative_url` was temporarily enhanced to write all inputs and output to disk when running the test suite. The added tests in this patch are a small selection thereof. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-03-01git: submodule honor -c credential.* from command lineLibravatar Jacob Keller1-13/+23
Due to the way that the git-submodule code works, it clears all local git environment variables before entering submodules. This is normally a good thing since we want to clear settings such as GIT_WORKTREE and other variables which would affect the operation of submodule commands. However, GIT_CONFIG_PARAMETERS is special, and we actually do want to preserve these settings. However, we do not want to preserve all configuration as many things should be left specific to the parent project. Add a git submodule--helper function, sanitize-config, which shall be used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs except a small subset that are known to be safe and necessary. Replace all the calls to clear_local_git_env with a wrapped function that filters GIT_CONFIG_PARAMETERS using the new helper and then restores it to the filtered subset after clearing the rest of the environment.

2016-02-24submodule: try harder to fetch needed sha1 by direct fetching sha1Libravatar Stefan Beller1-3/+26
When reviewing a change that also updates a submodule in Gerrit, a common review practice is to download and cherry-pick the patch locally to test it. However when testing it locally, the 'git submodule update' may fail fetching the correct submodule sha1 as the corresponding commit in the submodule is not yet part of the project history, but also just a proposed change. If $sha1 was not part of the default fetch, we try to fetch the $sha1 directly. Some servers however do not support direct fetch by sha1, which leads git-fetch to fail quickly. We can fail ourselves here as the still missing sha1 would lead to a failure later in the checkout stage anyway, so failing here is as good as we can get.

The infrastructure to rewrite "git submodule" in C is being built incrementally. Let's polish these early parts well enough and make them graduate to 'next' and 'master', so that the more involved follow-up can start cooking on a solid ground. * sb/submodule-helper: submodule: rewrite `module_clone` shell function in C submodule: rewrite `module_name` shell function in C submodule: rewrite `module_list` shell function in C

2015-09-23submodule: allow only certain protocols for submodule fetchesLibravatar Jeff King1-0/+9
Some protocols (like git-remote-ext) can execute arbitrary code found in the URL. The URLs that submodules use may come from arbitrary sources (e.g., .gitmodules files in a remote repository). Let's restrict submodules to fetching from a known-good subset of protocols. Note that we apply this restriction to all submodule commands, whether the URL comes from .gitmodules or not. This is more restrictive than we need to be; for example, in the tests we run: git submodule add ext::... which should be trusted, as the URL comes directly from the command line provided by the user. But doing it this way is simpler, and makes it much less likely that we would miss a case. And since such protocols should be an exception (especially because nobody who clones from them will be able to update the submodules!), it's not likely to inconvenience anyone in practice.

2015-09-08submodule: rewrite `module_clone` shell function in CLibravatar Stefan Beller1-76/+2
This reimplements the helper function `module_clone` in shell in C as `clone`. This functionality is needed for converting `git submodule update` later on, which we want to add threading to. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-03submodule: rewrite `module_name` shell function in CLibravatar Stefan Beller1-25/+7
This implements the helper `name` in C instead of shell, yielding a nice performance boost. Before this patch, I measured a time (best out of three): $ time ./t7400-submodule-basic.sh >/dev/null real 0m11.066s user 0m3.348s sys 0m8.534s With this patch applied I measured (also best out of three) $ time ./t7400-submodule-basic.sh >/dev/null real 0m10.063s user 0m3.044s sys 0m7.487s Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-03submodule: rewrite `module_list` shell function in CLibravatar Stefan Beller1-48/+6
Most of the submodule operations work on a set of submodules. Calculating and using this set is usually done via: module_list "$@" | { while read mode sha1 stage sm_path do # the actual operation done } Currently the function `module_list` is implemented in the git-submodule.sh as a shell script wrapping a perl script. The rewrite is in C, such that it is faster and can later be easily adapted when other functions are rewritten in C. git-submodule.sh, similar to the builtin commands, will navigate to the top-most directory of the repository and keep the subdirectory as a variable. As the helper is called from within the git-submodule.sh script, we are already navigated to the root level, but the path arguments are still relative to the subdirectory we were in when calling git-submodule.sh. That's why there is a `--prefix` option pointing to an alternative path which to anchor relative path arguments.
