73e9535d	2019-10-17T13:43:26	tests: submodule: test cloning edge cases Add two more tests that verify our behaviour in some edge cases, notably when cloning into a non-empty directory and when cloning the same submodule twice.
de412fc2	2019-10-17T13:36:22	tests: submodule: make use of sandboxes to clean repos The test submodule::add::submodule_clone doesn't use a sandbox, and thus the created repo will not get deleted after the test has finished. Convert the test to use the empty standard repo sandbox instead to fix this.
09b1ac11	2019-10-17T13:32:22	tests: submodule: fix tests for cloning submodules The test submodule::add::homemade_clone unfortunately doesn't test what's expected, but does instead clone the submodule to a directory that is outside of the parent repository. Fixing this by cloning to the correct location isn't possible, though, as `git_submodule_add_setup` will have pre-created a ".git" file already, which will cause `git_clone` to error out. As it's not possible to perform the clone without fiddling around with the repo's layout, let's just remove this test as that is in fact what the new `git_submodule_clone` function is for.
3c5d78bd	2019-05-01T16:16:26	submodule: provide a wrapper for simple submodule clone steps
e54343a4	2019-06-29T09:17:32	fileops: rename to "futils.h" to match function signatures Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.

8178c70f	2018-06-06T09:23:01	tests: submodule: do not rely on config iteration order The test submodule::lookup::duplicated_path, which tries to verify that we detect submodules with duplicated paths, currently relies on the gitmodules file of "submod2_target". While this file has two gitmodules with the same path, one of these gitmodules has an empty name and thus does not pass `git_submodule_name_is_valid`. Because of this, the test is in fact dependent on the iteration order in which we process the submodules. In fact the "valid" submodule comes first, the "invalid" submodule will cause the desired error. In fact the "invalid" submodule comes first, it will be skipped due to its name being invalid, and we will not see the desired error. While this works on the master branch just right due to the refactoring of our config code, where iteration order is now deterministic, this breaks on all older maintenance branches. Fix the issue by simply using `cl_git_rewritefile` to rewrite the gitmodules file. This greatly simplifies the test and also makes the intentions of it much clearer.
b2a389c8	2018-05-30T08:35:06	submodule: detect duplicated submodule paths When loading submodule names, we build a map of submodule paths and their respective names. While looping over the configuration keys, we do not check though whether a submodule path was seen already. This leads to a memory leak in case we have multiple submodules with the same path, as we just overwrite the old value in the map in that case. Fix the error by verifying that the path to be added is not yet part of the string map. Git does not allow to have multiple submodules for a path anyway, so we now do the same and detect this duplication, reporting it to the user.

397abe98	2018-05-14T16:03:15	submodule: also validate Windows-separated paths for validity Otherwise we would also admit `..\..\foo\bar` as a valid path and fail to protect Windows users. Ideally we would check for both separators without the need for the copied string, but this'll get us over the RCE.
6b15ceac	2018-04-30T13:47:15	submodule: ignore submodules which include path traversal in their name If the we decide that the "name" of the submodule (i.e. its path inside `.git/modules/`) is trying to escape that directory or otherwise trick us, we ignore the configuration for that submodule. This leaves us with a half-configured submodule when looking it up by path, but it's the same result as if the configuration really were missing. The name check is potentially more strict than it needs to be, but it lets us re-use the check we're doing for the checkout. The function that encapsulates this logic is ready to be exported but we don't want to do that in a security release so it remains internal for now.
7553763a	2018-04-30T13:03:44	submodule: add a failing test for a submodule escaping .git/modules We should pretend such submdules do not exist as it can lead to RCE.

477b3e04	2017-07-10T12:25:43	submodule: refuse lookup in bare repositories While it is technically possible to look up submodules inside of a bare repository by reading the submodule configuration of a specific commit, we do not offer this functionality right now. As such, calling both `git_submodule_lookup` and `git_submodule_foreach` should error out early when these functions encounter a bare repository. While `git_submodule_lookup` already does return an error due to not being able to parse the configuration, `git_submodule_foreach` simply returns success and never invokes the callback function. Fix the issue by having both functions check whether the repository is bare and returning an error in that case.

64d1e0b3	2017-07-10T11:52:08	tests: submodule: fix declaration of test The testcase "submodule::lookup::cached" was declared with a single underscore separating the test suide and test name, only. As the clar parser only catches tests with two underscores, it was never executed. Add in the second underscore to actually have it detected and executed.
2696c5c3	2017-05-19T09:21:17	repository: make check if repo is a worktree more strict To determine if a repository is a worktree or not, we currently check for the existence of a "gitdir" file inside of the repository's gitdir. While this is sufficient for non-broken repositories, we have at least one case of a subtly broken repository where there exists a gitdir file inside of a gitmodule. This will cause us to misidentify the submodule as a worktree. While this is not really a fault of ours, we can do better here by observing that a repository can only ever be a worktree iff its common directory and dotgit directory are different. This allows us to make our check whether a repo is a worktree or not more strict by doing a simple string comparison of these two directories. This will also allow us to do the right thing in the above case of a broken repository, as for submodules these directories will be the same. At the same time, this allows us to skip the `stat` check for the "gitdir" file for most repositories.
e526fbc7	2017-05-17T09:23:06	tests: add test suite for opening submodules
a1dcc830	2017-02-17T12:13:35	tests: provide better pass/failure error messages Provide more detailed messages when conditions pass or fail unexpectedly. In particular, this provides the error messages when a test fails with a different error code than was expected.
4d99c4cf	2016-11-23T18:32:48	Allow for caching of submodules. Added `git_repository_submodule_cache_all` to initialze a cache of submodules on the repository so that operations looking up N submodules are O(N) and not O(N^2). Added a `git_repository_submodule_cache_clear` function to remove the cache. Also optimized the function that loads all submodules as it was itself O(N^2) w.r.t the number of submodules, having to loop through the `.gitmodules` file once per submodule. I changed it to process the `.gitmodules` file once, into a map. Signed-off-by: David Turner <dturner@twosigma.com>

e8ddd8d7	2015-09-17T17:49:32	repo::reservedname: test a submodule update Test an initial submodule update, where we are trying to checkout the submodule for the first time, and placing a file within the submodule working directory with the same name as the submodule (and consequently, the same name as the repository itself).

ac2fba0e	2015-09-16T15:07:27	git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

a34c4f8d	2015-07-11T13:32:57	submdule: reproduce double-reporting of a submodule in foreach When we rename a submodule, we should be merging two sets of information based on whether their path is the same. We currently only deduplicate on equal name, which causes us to double-report.
e8e848a8	2015-07-01T21:10:40	submodule: add failing test for loading the wrong submodule When two submodules are fairly similar, we may end up loading the wrong one.
34065968	2015-07-01T17:49:07	submodule: completely remove reload_all The function was removed, but its declaration and changelog entry about its removal were forgotten. The comment in the test doesn't make any sense as the function doesn't exist anymore, so get rid of it as well.
c28a5c97	2015-06-29T21:10:47	submodule: remove trailing slashes from submodule paths We allow looking up a submodule by path, but we lost the path normalisation during the recent changes. Bring it back.

4536574a	2015-05-05T16:29:38	submodule: test more accurately for non-existence The current code will always fail, but only because it's asking for a string on a live config. Take a snapshot and make sure we fail with ENOTFOUND instead of any old error.
adb58f7d	2015-05-05T16:21:57	submodule: fix potential leak in the tests
961861fa	2015-05-05T09:25:17	submodule: get rid of `_save()` We no longer have any setters which affect an instance, so `git_submodule_save()` is no longer relevant.
d6073b30	2015-05-05T09:22:35	submodule: make `_set_url()` affect the configuration With this one, we can get rid of the edit_and_save test.
486ba4cd	2015-05-05T09:13:52	submodule: make `_set_branch()` affect the configuration
4e636423	2015-05-05T09:01:20	submodule: make `_set_update_fetch_recurse_submodules()` affect the config Similarly to the other ones. In this test we copy over testing `RECURSE_YES` which shows an error in our handling of the `YES` variant which we may have to port to the rest.
e8a39f8e	2015-05-05T08:35:29	submodule: make `_set_update()` affect the configuration Moving on with the removal of runtime-changing variables, the update setting for a remote is whatever it was when it was looked up.
c6f489c9	2015-05-04T17:29:12	submodule: add an ignore option to status This lets us specify in the status call which ignore rules we want to use (optionally falling back to whatever the submodule has in its configuration). This removes one of the reasons for having `_set_ignore()` set the value in-memory. We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.
64bbd47a	2015-05-04T17:09:21	submodule: don't let status change an existing instance As submodules are becomes more like values, we should not let a status check to update its properties. Instead of taking a submodule, have status take a repo and submodule name.
5a9fc6c8	2015-05-04T16:22:56	submodule: make set_ignore() affect the configuration Instead of affecting a particular instance, make it change the configuration.
dfda2f68	2015-04-27T19:27:29	submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.
3e529e9d	2015-05-13T16:12:45	Fix a few leaks The interesting one is the notification macro, which was returning directly on a soft-abort instead of going through the cleanup.
8f0104ec	2015-04-21T22:10:36	Remove the callbacks struct from the remote Having the setting be different from calling its actions was not a great idea and made for the sake of the wrong convenience. Instead of that, accept either fetch options, push options or the callbacks when dealing with the remote. The fetch options are currently only the callbacks, but more options will be moved from setters and getters on the remote to the options. This does mean passing the same struct along the different functions but the typical use-case will only call git_remote_fetch() or git_remote_push() and so won't notice much difference.
129788a6	2015-03-18T11:45:18	Implement git_submodule_set_branch.
e6903ea2	2015-03-12T16:05:07	Fix git_submodule_sync writing URL to wrong key. Currently git_submodule_sync writes the submodule's URL to the key 'branch.<REMOTE_NAME>.remote' while the reference implementation of `git submodule sync` writes to 'remote.<REMOTE_NAME>.url', which is the intended behavior according to git-submodule(1).
9a97f49e	2014-12-21T15:31:03	config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.
4e498646	2015-01-15T16:50:31	repository: remove log message override for switching the active branch We want to use the "checkout: moving from ..." message in order to let git know when a change of branch has happened. Make the convenience functions for this goal write this message.
659cf202	2015-01-07T12:23:05	Remove the signature from ref-modifying functions The signature for the reflog is not something which changes dynamically. Almost all uses will be NULL, since we want for the repository's default identity to be used, making it noise. In order to allow for changing the identity, we instead provide git_repository_set_ident() and git_repository_ident() which allow a user to override the choice of signature.

9d1f97df	2014-10-29T17:49:04	Introduce a convenience function for submodule update This introduces the functionality of submodule update in 'git_submodule_do_update'. The existing 'git_submodule_update' function is renamed to 'git_submodule_update_strategy'. The 'git_submodule_update' function now refers to functionality similar to `git submodule update`, while `git_submodule_update_strategy` is used to get the configured value of submodule.<name>.update.
b2ab887e	2014-10-20T18:07:32	submodule init should resolve relative url paths Submodule init should handle relative paths in .gitmodules files and resolve these urls when updating the git config file.
209425ce	2014-11-08T13:25:51	remote: rename _load() to _lookup() This brings it in line with the rest of the lookup functions.
62a617dc	2014-11-06T16:16:46	iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

46c8f7f8	2014-10-24T16:25:59	remote: accept a repo and name for renaming Remote objects are not meant to be changed from under the user. We did this in rename, but only the name and left the refspecs, such that a save would save the wrong refspecs (and a fetch and anything else would use the wrong refspecs). Instead, let's simply take a name and not change any loaded remote from under the user.
bc737620	2014-08-20T10:24:41	Introduce option to use relative paths for repository work directory Teach git_repository_init_ext to use relative paths for the gitlink to the work directory.

8f4e5275	2014-04-01T16:46:25	More tests and fix submodule index refresh There was a little bug where the submodule cache thought that the index date was out of date even when it wasn't that was resulting in some extra scans of index data even when not needed. Mostly this commit adds a bunch of new tests including adding and removing submodules in the index and in the HEAD and seeing if we can automatically pick them up when refreshing.
8061d519	2014-04-01T13:24:06	Remove most submodule reloads from tests With the new submodule cache validity checks, we generally don't need to call git_submodule_reload_all to have up-to-date submodule data. Some tests are still calling it where I want to actually test that it can be called safely and doesn't break anything, but mostly it is not needed. This also expands some of the existing submodule tests to cover some variants on the behavior that was already being tested.
4ece3e22	2014-04-01T12:19:11	Fix submodule accounting for name and path changes Wrote tests that try adding, removing, and updating the name of submodules which showed a number of problems with how we account for changes when incrementally updating the submodule info. Most of these issues didn't exist before because reloading would always blow away the old submodule data.
380f864a	2014-03-26T16:06:21	Fix error when submodule path and name differ When a submodule was inserted with a different path and name, the return value from khash greater than zero was allowed to propagate back out to the caller when it should really be zeroed. This led to a possible crash when reloading submodules if that was the first time that submodule data was loaded.
22df47cb	2014-03-26T14:38:26	Fix segfault if gitmodules is invalid The reload_all call could end up dereferencing a NULL pointer if there was an error while attempting to load the submodules config data (i.e. invalid content in the gitmodules file). This fixes it.

d3bc95fd	2014-03-25T12:37:05	Update behavior for untracked sub-repos When a directory containing a .git directory (or even just a plain gitlink) was found, libgit2 was going out of its way to treat it specially. This seemed like it was necessary because the diff code was not originally emulating Git's behavior for untracked directories correctly (i.e. scanning for ignored vs untracked items inside). Now that libgit2 diff mimics Git's untracked directory behavior, the special handling for contained Git repos is actually incorrect and this commit rips it out.
a15c7802	2014-03-25T09:14:48	Make submodules externally refcounted `git_submodule` objects were already refcounted internally in case the submodule name was different from the path at which it was stored. This makes that refcounting externally used as well, so `git_submodule_lookup` and `git_submodule_add_setup` return an object that requires a `git_submodule_free` when done.
c0644c3f	2014-01-28T11:45:06	Make submodule fetchRecurse match other options This removes the fetchRecurse compiler warnings and makes the behavior match the other submodule options (i.e. the in-memory setting can be reset to the on-disk value).

tests: submodule: fix tests for cloning submodules The test submodule::add::homemade_clone unfortunately doesn't test what's expected, but does instead clone the submodule to a directory that is outside of the parent repository. Fixing this by cloning to the correct location isn't possible, though, as `git_submodule_add_setup` will have pre-created a ".git" file already, which will cause `git_clone` to error out. As it's not possible to perform the clone without fiddling around with the repo's layout, let's just remove this test as that is in fact what the new `git_submodule_clone` function is for.

fileops: rename to "futils.h" to match function signatures Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.

tests: submodule: do not rely on config iteration order The test submodule::lookup::duplicated_path, which tries to verify that we detect submodules with duplicated paths, currently relies on the gitmodules file of "submod2_target". While this file has two gitmodules with the same path, one of these gitmodules has an empty name and thus does not pass `git_submodule_name_is_valid`. Because of this, the test is in fact dependent on the iteration order in which we process the submodules. In fact the "valid" submodule comes first, the "invalid" submodule will cause the desired error. In fact the "invalid" submodule comes first, it will be skipped due to its name being invalid, and we will not see the desired error. While this works on the master branch just right due to the refactoring of our config code, where iteration order is now deterministic, this breaks on all older maintenance branches. Fix the issue by simply using `cl_git_rewritefile` to rewrite the gitmodules file. This greatly simplifies the test and also makes the intentions of it much clearer.

submodule: detect duplicated submodule paths When loading submodule names, we build a map of submodule paths and their respective names. While looping over the configuration keys, we do not check though whether a submodule path was seen already. This leads to a memory leak in case we have multiple submodules with the same path, as we just overwrite the old value in the map in that case. Fix the error by verifying that the path to be added is not yet part of the string map. Git does not allow to have multiple submodules for a path anyway, so we now do the same and detect this duplication, reporting it to the user.

submodule: ignore submodules which include path traversal in their name If the we decide that the "name" of the submodule (i.e. its path inside `.git/modules/`) is trying to escape that directory or otherwise trick us, we ignore the configuration for that submodule. This leaves us with a half-configured submodule when looking it up by path, but it's the same result as if the configuration really were missing. The name check is potentially more strict than it needs to be, but it lets us re-use the check we're doing for the checkout. The function that encapsulates this logic is ready to be exported but we don't want to do that in a security release so it remains internal for now.

submodule: refuse lookup in bare repositories While it is technically possible to look up submodules inside of a bare repository by reading the submodule configuration of a specific commit, we do not offer this functionality right now. As such, calling both `git_submodule_lookup` and `git_submodule_foreach` should error out early when these functions encounter a bare repository. While `git_submodule_lookup` already does return an error due to not being able to parse the configuration, `git_submodule_foreach` simply returns success and never invokes the callback function. Fix the issue by having both functions check whether the repository is bare and returning an error in that case.

repository: make check if repo is a worktree more strict To determine if a repository is a worktree or not, we currently check for the existence of a "gitdir" file inside of the repository's gitdir. While this is sufficient for non-broken repositories, we have at least one case of a subtly broken repository where there exists a gitdir file inside of a gitmodule. This will cause us to misidentify the submodule as a worktree. While this is not really a fault of ours, we can do better here by observing that a repository can only ever be a worktree iff its common directory and dotgit directory are different. This allows us to make our check whether a repo is a worktree or not more strict by doing a simple string comparison of these two directories. This will also allow us to do the right thing in the above case of a broken repository, as for submodules these directories will be the same. At the same time, this allows us to skip the `stat` check for the "gitdir" file for most repositories.

Allow for caching of submodules. Added `git_repository_submodule_cache_all` to initialze a cache of submodules on the repository so that operations looking up N submodules are O(N) and not O(N^2). Added a `git_repository_submodule_cache_clear` function to remove the cache. Also optimized the function that loads all submodules as it was itself O(N^2) w.r.t the number of submodules, having to loop through the `.gitmodules` file once per submodule.

This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

Remove the callbacks struct from the remote Having the setting be different from calling its actions was not a great idea and made for the sake of the wrong convenience. Instead of that, accept either fetch options, push options or the callbacks when dealing with the remote. The fetch options are currently only the callbacks, but more options will be moved from setters and getters on the remote to the options. This does mean passing the same struct along the different functions but the typical use-case will only call git_remote_fetch() or git_remote_push() and so won't notice much difference.

config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

Update behavior for untracked sub-repos When a directory containing a .git directory (or even just a plain gitlink) was found, libgit2 was going out of its way to treat it specially. This seemed like it was necessary because the diff code was not originally emulating Git's behavior for untracked directories correctly (i.e. scanning for ignored vs untracked items inside). Now that libgit2 diff mimics Git's untracked directory behavior, the special handling for contained Git repos is actually incorrect and this commit rips it out.
