2018-10-31submodule: support reading .gitmodules when it's not in the working treeLibravatar Antonio Ospite1-2/+29
When the .gitmodules file is not available in the working tree, try using the content from the index and from the current branch. This covers the case when the file is part of the repository but for some reason it is not checked out, for example because of a sparse checkout. This makes it possible to use at least the 'git submodule' commands which *read* the gitmodules configuration file without fully populating the working tree. Writing to .gitmodules will still require that the file is checked out, so check for that before calling config_set_in_gitmodules_file_gently. Add a similar check also in git-submodule.sh::cmd_add() to anticipate the eventual failure of the "git submodule add" command when .gitmodules is not safely writeable; this prevents the command from leaving the repository in a spurious state (e.g. the submodule repository was cloned but .gitmodules was not updated because config_set_in_gitmodules_file_gently failed). Moreover, since config_from_gitmodules() now accesses the global object store, it is necessary to protect all code paths which call the function against concurrent access to the global object store. Currently this only happens in builtin/grep.c::grep_submodules(), so call grep_read_lock() before invoking code involving config_from_gitmodules(). Finally, add t7418-submodule-sparse-gitmodules.sh to verify that reading from .gitmodules succeeds and that writing to it fails when the file is not checked out. NOTE: there is one rare case where this new feature does not work properly yet: nested submodules without .gitmodules in their working tree. This has been documented with a warning and a test_expect_failure item in t7814, and in this case the current behavior is not altered: no config is read.

2018-10-09submodule: factor out a config_set_in_gitmodules_file_gently functionLibravatar Antonio Ospite1-0/+12
Introduce a new config_set_in_gitmodules_file_gently() function to write config values to the .gitmodules file. This is in preparation for a future change which will use the function to write to the .gitmodules file in a more controlled way instead of using "git config -f .gitmodules". The purpose of the change is mainly to centralize the code that writes to the .gitmodules file to avoid some duplication. The naming follows git_config_set_in_file_gently() but the git_ prefix is removed to communicate that this is not a generic git-config API.

2018-09-27submodule-config: ban submodule paths that start with a dashLibravatar Jeff King1-0/+2
We recently banned submodule urls that look like command-line options. This is the matching change to ban leading-dash paths. As with the urls, this should not break any use cases that currently work. Even with our "--" separator passed to git-clone, git-submodule.sh gets confused. Without the code portion of this patch, the clone of "-sub" added in t7417 would yield results like: /path/to/git-submodule: 410: cd: Illegal option -s /path/to/git-submodule: 417: cd: Illegal option -s /path/to/git-submodule: 410: cd: Illegal option -s /path/to/git-submodule: 417: cd: Illegal option -s Fetched in submodule path '-sub', but it did not contain b56243f8f4eb91b2f1f8109452e659f14dd3fbe4. Direct fetching of that commit failed. Moreover, naively adding such a submodule doesn't work: $ git submodule add $url -sub The following path is ignored by one of your .gitignore files: -sub even though there is no such ignore pattern (the test script hacks around this with a well-placed "git mv"). Unlike leading-dash urls, though, it's possible that such a path _could_ be useful if we eventually made it work. So this commit should be seen not as recommending a particular policy, but rather temporarily closing off a broken and possibly dangerous code-path. We may revisit this decision later. There are two minor differences to the tests in t7416 (that covered urls): 1. We don't have a "./-sub" escape hatch to make this work, since the submodule code expects to be able to match canonical index names to the path field (so you are free to add submodule config with that path, but we would never actually use it, since an index entry would never start with "./"). 2. After this patch, cloning actually succeeds. Since we ignore the submodule.*.path value, we fail to find a config stanza for our submodule at all, and simply treat it as inactive. We still check for the "ignoring" message. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-09-27submodule-config: ban submodule urls that start with dashLibravatar Jeff King1-0/+8
The previous commit taught the submodule code to invoke our "git clone $url $path" with a "--" separator so that we aren't confused by urls or paths that start with dashes. However, that's just one code path. It's not clear if there are others, and it would be an easy mistake to add one in the future. Moreover, even with the fix in the previous commit, it's quite hard to actually do anything useful with such an entry. Any url starting with a dash must fall into one of three categories: - it's meant as a file url, like "-path". But then any clone is not going to have the matching path, since it's by definition relative inside the newly created clone. If you spell it as "./-path", the submodule code sees the "/" and translates this to an absolute path, so it at least works (assuming the receiver has the same filesystem layout as you). But that trick does not apply for a bare "-path". - it's meant as an ssh url, like "-host:path". But this already doesn't work, as we explicitly disallow ssh hostnames that begin with a dash (to avoid option injection against ssh). - it's a remote-helper scheme, like "-scheme::data". This _could_ work if the receiver bends over backwards and creates a funny-named helper like "git-remote--scheme". But normally there would not be any helper that matches. Since such a url does not work today and is not likely to do anything useful in the future, let's simply disallow them entirely. That protects the existing "git clone" path (in a belt-and-suspenders way), along with any others that might exist. Our tests cover two cases: 1. A file url with "./" continues to work, showing that there's an escape hatch for people with truly silly repo names. 2. A url starting with "-" is rejected. Note that we expect case (2) to fail, but it would have done so even without this commit, for the reasons given above. So instead of just expecting failure, let's also check for the magic word "ignoring" on stderr. That lets us know that we failed for the right reason.

2018-08-29convert "oidcmp() != 0" to "!oideq()"Libravatar Jeff King1-2/+2
This is the flip side of the previous two patches: checking for a non-zero oidcmp() can be more strictly expressed as inequality. Like those patches, we write "!= 0" in the coccinelle transformation, which covers by isomorphism the more common: if (oidcmp(E1, E2)) As with the previous two patches, this patch can be achieved almost entirely by running "make coccicheck"; the only differences are manual line-wrap fixes to match the original code. There is one thing to note for anybody replicating this, though: coccinelle 1.0.4 seems to miss the case in builtin/tag.c, even though it's basically the same as all the others. Running with 1.0.7 does catch this, so presumably it's just a coccinelle bug that was fixed in the interim. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.

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>

Many uses of comparision callback function the hashmap API uses cast the callback function type when registering it to hashmap_init(), which defeats the compile time type checking when the callback interface changes (e.g. gaining more parameters).

2017-08-07treewide: deprecate git_config_maybe_bool, use git_parse_maybe_boolLibravatar Martin Ågren1-2/+2
The only difference between these is that the former takes an argument `name` which it ignores completely. Still, the callers are quite careful to provide reasonable values for it. Once in-flight topics have landed, we should be able to remove git_config_maybe_bool. In the meantime, document it as deprecated in the technical documentation. While at it, document git_parse_maybe_bool. Signed-off-by: Martin Ågren <martin.agren@gmail.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.

2017-08-02submodule: remove submodule.fetchjobs from submodule-config parsingLibravatar Brandon Williams1-0/+8
The '.gitmodules' file should only contain information pertinent to configuring individual submodules (name to path mapping, URL where to obtain the submodule, etc.) while other configuration like the number of jobs to use when fetching submodules should be a part of the repository's config. Remove the 'submodule.fetchjobs' configuration option from the general submodule-config parsing and instead rely on using the 'config_from_gitmodules()' in order to maintain backwards compatibility with this config being placed in the '.gitmodules' file.
