Etienne Samson 3c5d78bd 2019-05-01T16:16:26 submodule: provide a wrapper for simple submodule clone steps
Patrick Steinhardt 658022c4 2019-07-18T13:53:41 configuration: cvar -> configmap `cvar` is an unhelpful name. Refactor its usage to `configmap` for more clarity.
Edward Thomson 0b5ba0d7 2019-06-06T16:36:23 Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.
Patrick Steinhardt c50a8ac2 2018-12-01T08:59:24 maps: use high-level function to check existence of keys Some callers were still using the tightly-coupled pattern of `lookup_index` and `valid_index` to verify that an entry exists in a map. Instead, use the more high-level `exists` functions to decouple map users from its implementation.
Patrick Steinhardt 03555830 2019-01-23T10:44:33 strmap: introduce high-level setter for key/value pairs Currently, one would use the function `git_strmap_insert` to insert key/value pairs into a map. This function has historically been a macro, which is why its syntax is kind of weird: instead of returning an error code directly, it instead has to be passed a pointer to where the return value shall be stored. This does not match libgit2's common idiom of directly returning error codes. Introduce a new function `git_strmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all callers of `git_strmap_insert` to make use of it.
Patrick Steinhardt ef507bc7 2019-01-23T10:44:02 strmap: introduce `git_strmap_get` and use it throughout the tree The current way of looking up an entry from a map is tightly coupled with the map implementation, as one first has to look up the index of the key and then retrieve the associated value by using the index. As a caller, you usually do not care about any indices at all, though, so this is more complicated than really necessary. Furthermore, it invites for errors to happen if the correct error checking sequence is not being followed. Introduce a new high-level function `git_strmap_get` that takes a map and a key and returns a pointer to the associated value if such a key exists. Otherwise, a `NULL` pointer is returned. Adjust all callers that can trivially be converted.
Patrick Steinhardt 7e926ef3 2018-11-30T12:14:43 maps: provide a uniform entry count interface There currently exist two different function names for getting the entry count of maps, where offmaps offset and string maps use `num_entries` and OID maps use `size`. In most programming languages with built-in map types, this is simply called `size`, which is also shorter to type. Thus, this commit renames the other two functions `num_entries` to match the common way and adjusts all callers.
Patrick Steinhardt 351eeff3 2019-01-23T10:42:46 maps: use uniform lifecycle management functions Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.
Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
Etienne Samson 9c23552c 2018-10-24T01:21:21 submodule: grab the error while loading from config Previously, an error in `git_config_next` would be mistaken as a successful load, because the previous call would have succeeded. Coverity saw the subsequent check for a completed iteration as dead, so let's make it useful again. CID 1391374
Edward Thomson 168fe39b 2018-11-28T14:26:57 object_type: use new enumeration names Use the new object_type enumeration names within the codebase.
Edward Thomson 18e71e6d 2018-11-28T13:31:06 index: use new enum and structure names Use the new-style index names throughout our own codebase.
Patrick Steinhardt 852bc9f4 2018-11-23T19:26:24 khash: remove intricate knowledge of khash types Instead of using the `khiter_t`, `git_strmap_iter` and `khint_t` types, simply use `size_t` instead. This decouples code from the khash stuff and makes it possible to move the khash includes into the implementation files.
Patrick Steinhardt ae765d00 2018-11-23T19:26:48 submodule: remove string map implementation that strips trailing slashes The submodule code currently has its own implementation of a string map, which overrides the hashing and hash equals functions with functions that ignore potential trailing slashes. These functions aren't actually used by our code, making them useless.
Carlos Martín Nieto c8ca3cae 2018-10-05T11:47:39 submodule: ignore path and url attributes if they look like options These can be used to inject options in an implementation which performs a recursive clone by executing an external command via crafted url and path attributes such that it triggers a local executable to be run. The library is not vulnerable as we do not rely on external executables but a user of the library might be relying on that so we add this protection. This matches this aspect of git's fix for CVE-2018-17456.
Patrick Steinhardt b944e137 2018-08-10T13:03:33 config: rename "config_file.h" to "config_backend.h" The header "config_file.h" has a list of inline-functions to access the contents of a config backend without directly messing with the struct's function pointers. While all these functions are called "git_config_file_*", they are in fact completely backend-agnostic and don't care whether it is a file or not. Rename all the function to instead be backend-agnostic versions called "git_config_backend_*" and rename the header to match.
Patrick Steinhardt 0b9c68b1 2018-08-16T14:10:58 submodule: fix submodule names depending on config-owned memory When populating the list of submodule names, we use the submodule configuration entry's name as the key in the map of submodule names. This creates a hidden dependency on the liveliness of the configuration that was used to parse the submodule, which is fragile and unexpected. Fix the issue by duplicating the string before writing it into the submodule name map.
Etienne Samson 36a5b557 2018-06-19T20:18:26 submodule: don't leak memory when failing to insert the names Reported by Coverity, CID 1393237
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Patrick Steinhardt 9c698a25 2018-05-30T10:34:58 submodule: remove useless mask computations Previous to dfda2f68e (submodule: remove the per-repo cache, 2015-04-27), we tried to cache our submodules per repository to avoid having to reload it too frequently. As it created some headaches with regards to multithreading, we removed that cache. Previous to that removal, we had to compute what submodule status to refresh. The mask computation was not removed, though, resulting in confusing and actually dead code. While it seems like the mask is currently in use in a conditional, it is not, as we unconditionally assign to the mask previous to that condition. Remove all mask computations to clean up stale code.
Patrick Steinhardt cf5030a3 2018-05-30T08:38:28 submodule: refactor loading submodule names The function `load_submodule_names` was always being called with a newly allocated string map, which was then getting filled by the function. Move the string map allocation into `load_submodule_names`, instead, and pass the whole map back to the caller in case no error occurs. This change helps to avoid misuse by handing in pre-populated maps.
Patrick Steinhardt 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.
Carlos Martín Nieto 9e723db8 2018-05-24T20:28:36 submodule: plug leaks from the escape detection
Carlos Martín Nieto c16ebaa6 2018-05-24T19:05:59 submodule: replace index with strchr which exists on Windows
Carlos Martín Nieto 91a4849d 2018-05-24T19:00:13 submodule: the repostiory for _name_is_valid should not be const We might modify caches due to us trying to load the configuration to figure out what kinds of filesystem protections we should have.
Carlos Martín Nieto a7168b47 2018-05-22T16:13:47 path: reject .gitmodules as a symlink Any part of the library which asks the question can pass in the mode to have it checked against `.gitmodules` being a symlink. This is particularly relevant for adding entries to the index from the worktree and for checking out files.
Carlos Martín Nieto 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.
Carlos Martín Nieto 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.

Patrick Steinhardt 529e873c 2017-05-23T11:51:00 config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.
Patrick Steinhardt 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.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Edward Thomson f623cf89 2017-03-22T20:32:55 Merge pull request #4163 from pks-t/pks/submodules-with-worktrees Worktree fixes
Patrick Steinhardt b0c9bc92 2017-03-15T13:38:54 submodule: resolve URLs relative to main worktree It is possible to specify submodule URLs relative to the repository location. E.g. having a submodule with URL "../submodule" will look for the submodule at "repo/../submodule". With the introduction of worktrees, though, we cannot simply resolve the URL relative to the repository location itself. If the repository for which a URL is to be resolved is a working tree, we have to resolve the URL relative to the parent's repository path. Otherwise, the URL would change depending on where the working tree is located. Fix this by special-casing when we have a working tree while getting the URL base.
Patrick Steinhardt 32ecc98e 2017-03-14T14:53:32 submodule: catch when submodule is not staged on update When calling `git_submodule_update` on a submodule, we have to retrieve the ID of the submodule entry in the index. If the function is called on a submodule which is only partly initialized, the submodule entry may not be added to the index yet. This leads to an assert when trying to look up the blob later on. Fix the issue by checking if the index actually holds the submodule's ID and erroring out if it does not.

Patrick Steinhardt c5f3da96 2016-11-11T14:36:43 repository: use `git_repository_item_path` The recent introduction of the commondir variable of a repository requires callers to distinguish whether their files are part of the dot-git directory or the common directory shared between multpile worktrees. In order to take the burden from callers and unify knowledge on which files reside where, the `git_repository_item_path` function has been introduced which encapsulate this knowledge. Modify most existing callers of `git_repository_path` to use `git_repository_item_path` instead, thus making them implicitly aware of the common directory.

Brock Peabody 673dff88 2016-11-23T18:32:55 Skip submodule head/index update when caching. `git_submodule_status` is very slow, bottlenecked on `git_repository_head_tree`, which it uses through `submodule_update_head`. If the user has requested submodule caching, assume that they want this status cached too and skip it. Signed-off-by: David Turner <dturner@twosigma.com>
Brock Peabody 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>

Patrick Steinhardt 486302d6 2016-03-01T19:11:33 submodule: avoid passing NULL pointers to strncmp In C89 it is undefined behavior to pass `NULL` pointers to `strncmp` and later on in C99 it has been explicitly stated that functions with an argument declared as `size_t nmemb` specifying the array length shall always have valid parameters, no matter if `nmemb` is 0 or not (see ISO 9899 §7.21.1.2). The function `str_equal_no_trailing_slash` always passes its parameters to `strncmp` if their lengths match. This means if one parameter is `NULL` and the other one either `NULL` or a string with length 0 we will pass the pointers to `strncmp` and cause undefined behavior. Fix this by explicitly handling the case when both lengths are 0.

Add the missing '\.' in the regex so we want a full stop to exist both before and after the submodule name.

Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Carlos Martín Nieto 5a9fc6c8 2015-05-04T16:22:56 submodule: make set_ignore() affect the configuration Instead of affecting a particular instance, make it change the configuration.
Carlos Martín Nieto 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.
Carlos Martín Nieto 624c949f 2015-06-20T16:17:28 index: make relative comparison use the checksum as well This is used by the submodule in order to figure out if the index has changed since it last read it. Using a timestamp is racy, so let's make it use the checksum, just like we now do for reloading the index itself.
Carlos Martín Nieto 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.
Patrick Steinhardt 129788a6 2015-03-18T11:45:18 Implement git_submodule_set_branch.
Patrick Steinhardt 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).
Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Stefan Widgren c8e02b87 2015-02-15T21:07:05 Remove extra semicolon outside of a function Without this change, compiling with gcc and pedantic generates warning: ISO C does not allow extra ‘;’ outside of a function.
David Calavera c868981f 2015-01-06T13:49:39 Add extern function to initialize submodule update options.
Edward Thomson 5018e2c6 2015-01-06T17:08:38 submodule: declare vars at top of func block
