2018-06-26submodule-config: reuse config_from_gitmodules in repo_read_gitmodulesLibravatar Antonio Ospite1-29/+21
Reuse config_from_gitmodules in repo_read_gitmodules to remove some duplication and also have a single point where the .gitmodules file is read. The change does not introduce any new behavior, the same gitmodules_cb config callback is still used, which only deals with configuration specific to submodules. The check about the repo's worktree is removed from repo_read_gitmodules because it's already performed in config_from_gitmodules. The config_from_gitmodules function is moved up in the file —unchanged— before its users to avoid a forward declaration.

2018-06-26submodule-config: add helper to get 'update-clone' config from .gitmodulesLibravatar Antonio Ospite1-0/+14
Add a helper function to make it clearer that retrieving 'update-clone' configuration from the .gitmodules file is a special case supported solely for backward compatibility purposes. This change removes one direct use of 'config_from_gitmodules' for options not strictly related to submodules: "submodule.fetchjobs" does not describe a property of a submodule, but a behavior of other commands when dealing with submodules, so it does not really belong to the .gitmodules file. This is in the effort to communicate better that .gitmodules is not to be used as a mechanism to store arbitrary configuration in the repository that any command can retrieve.

2018-05-21submodule-config: verify submodule names as pathsLibravatar Jeff King1-0/+31
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>
2018-05-16object-store: move object access functions to object-store.hLibravatar Stefan Beller1-0/+1
This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used. That can happen later when we have better tooling for it. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-08-03submodule-config: lazy-load a repository's .gitmodules fileLibravatar Brandon Williams1-5/+22
In order to use the submodule-config subsystem, callers first need to initialize it by calling 'repo_read_gitmodules()' or 'gitmodules_config()' (which just redirects to 'repo_read_gitmodules()'). There are a couple of callers who need to load an explicit revision of the repository's .gitmodules file (grep) or need to modify the .gitmodules file so they would need to load it before modify the file (checkout), but the majority of callers are simply reading the .gitmodules file present in the working tree. For the common case it would be nice to avoid the boilerplate of initializing the submodule-config system before using it, so instead let's perform lazy-loading of the submodule-config system. Remove the calls to reading the gitmodules file from ls-files to show that lazy-loading the .gitmodules file works.

2017-06-30hashmap.h: compare function has access to a data fieldLibravatar Stefan Beller1-6/+8
When using the hashmap a common need is to have access to caller provided data in the compare function. A couple of times we abuse the keydata field to pass in the data needed. This happens for example in patch-ids.c. This patch changes the function signature of the compare function to have one more void pointer available. The pointer given for each invocation of the compare function must be defined in the init function of the hashmap and is just passed through. Documentation of this new feature is deferred to a later patch. This is a rather mechanical conversion, just adding the new pass-through parameter. However while at it improve the naming of the fields of all compare functions used by hashmaps by ensuring unused parameters are prefixed with 'unused_' and naming the parameters what they are (instead of 'unused' make it 'unused_keydata').

Code to read submodule.<name>.ignore config did not state the variable name correctly when giving an error message diagnosing misconfiguration. * sb/submodule-config-parse-ignore-fix: submodule-config: correct error reporting for invalid ignore value
2017-03-15update submodules: add submodule config parsingLibravatar Stefan Beller1-0/+20
Similar to b33a15b08 (push: add recurseSubmodules config option, 2015-11-17) and 027771fcb1 (submodule: allow erroneous values for the fetchRecurseSubmodules option, 2015-08-17), we add submodule-config code that is later used to parse whether we are interested in updating submodules. We need the `die_on_error` parameter to be able to call this parsing function for the config file as well, which if incorrect lets Git die. As we're just touching the header file, also mark all functions extern. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-15submodule-config: correct error reporting for invalid ignore valueLibravatar Stefan Beller1-1/+1
As 'var' contains the whole value we get error messages that repeat the section and key currently: warning: Invalid parameter 'true' for config option 'submodule.submodule.plugins/hooks.ignore.ignore' Fix this by only giving the section name in the warning.

2016-12-22submodules: load gitmodules file from commit sha1Libravatar Brandon Williams1-3/+3
teach submodules to load a '.gitmodules' file from a commit sha1. This enables the population of the submodule_cache to be based on the state of the '.gitmodules' file from a particular commit. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add the `RECURSE_SUBMODULES_ONLY` enum value to submodule.h. This enum value will be used in a later patch to push to indicate that only submodules should be pushed, while the superproject should remain unpushed.

2016-11-22submodule-config: rename commit_sha1 to treeish_nameLibravatar Stefan Beller1-23/+23
It is also possible to pass in any treeish name to lookup a submodule config. Make it clear by naming the variables accordingly. Looking up a submodule config by tree hash will come in handy in a later patch.
