Patrick Steinhardt 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.
Patrick Steinhardt 2e0a3048 2019-01-23T10:48:55 oidmap: introduce high-level setter for key/value pairs Currently, one would use either `git_oidmap_insert` to insert key/value pairs into a map or `git_oidmap_put` to insert a key only. These function have historically been macros, which is why their syntax is kind of weird: instead of returning an error code directly, they instead have 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.Furthermore, `git_oidmap_put` is tightly coupled with implementation details of the map as it exposes the index of inserted entries. Introduce a new function `git_oidmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all trivial callers of `git_oidmap_insert` and `git_oidmap_put` to make use of it.
Patrick Steinhardt 9694ef20 2018-12-17T09:01:53 oidmap: introduce high-level getter for values 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_oidmap_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 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.

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 b6276ae0 2018-03-29T09:15:48 odb: mempack: fix leaking objects when freeing mempacks When a ODB mempack gets free'd, we take no measures at all to free its contents, most notably the objects added to the database, resulting in a memory leak. Call `git_mempack_reset` previous to freeing the ODB structures themselves, which takes care of releasing all associated data structures.
Adrián Medraño Calvo d23ce187 2018-01-22T11:55:28 odb: export mempack backend Fixes #4492, #4496.
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.

Bryan Woods 707f6537 2015-09-11T16:35:14 Removing memory leak in mempack's free It calls git_mempack_reset which reallocates the object array. git_oidmap_free is now called on it explicitly.

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.
Edward Thomson 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.
