d103f008	2019-05-21T13:44:47	pool: use `size_t` for sizes
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.
84a089da	2018-12-01T08:50:36	maps: provide return value when deleting entries Currently, the delete functions of maps do not provide a return value. Like this, it is impossible to tell whether the entry has really been deleted or not. Change the implementation to provide either a return value of zero if the entry has been successfully deleted or `GIT_ENOTFOUND` if the key could not be found. Convert callers to the `delete_at` functions to instead use this higher-level interface.
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.
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.
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.
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.
2480d0eb	2017-06-30T13:34:05	Add missing license headers Some implementation files were missing the license headers. This commit adds them.

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.
f1453c59	2015-02-12T12:19:37	Make our overflow check look more like gcc/clang's Make our overflow checking look more like gcc and clang's, so that we can substitute it out with the compiler instrinsics on platforms that support it. This means dropping the ability to pass `NULL` as an out parameter. As a result, the macros also get updated to reflect this as well.
392702ee	2015-02-09T23:41:13	allocations: test for overflow of requested size Introduce some helper macros to test integer overflow from arithmetic and set error message appropriately.
7d490872	2014-04-10T22:31:01	Attribute file cache refactor This is a big refactoring of the attribute file cache to be a bit simpler which in turn makes it easier to enforce a lock around any updates to the cache so that it can be used in a threaded env. Tons of changes to the attributes and ignores code.
40ed4990	2014-02-11T14:45:37	Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.
882c7742	2014-02-04T10:01:37	Convert pqueue to just be a git_vector This updates the git_pqueue to simply be a set of specialized init/insert/pop functions on a git_vector. To preserve the pqueue feature of having a fixed size heap, I converted the "sorted" field in git_vectors to a more general "flags" field so that pqueue could mix in it's own flag. This had a bunch of ramifications because a number of places were directly looking at the vector "sorted" field - I added a couple new git_vector helpers (is_sorted, set_sorted) so the specific representation of this information could be abstracted.
805755f4	2013-08-22T15:44:34	Fix sortedcache docs and other feedback This converts an internal lock from a write lock to a read lock where write isn't needed, and also clarifies some doc things about where various locks are acquired and how various APIs are intended to be used.

0b7cdc02	2013-08-20T15:18:48	Add sorted cache data type This adds a convenient new data type for caching the contents of file in memory when each item in that file corresponds to a name and you need to both be able to lookup items by name and iterate over them in some sorted order. The new data type has locks in place to manage usage in a threaded environment.
