Patrick Steinhardt 9d117e20 2019-04-05T10:22:46 ignore: treat paths with trailing "/" as directories The function `git_ignore_path_is_ignored` is there to test the ignore status of paths that need not necessarily exist inside of a repository. This has the implication that for a given path, we cannot always decide whether it references a directory or a file, and we need to distinguish those cases because ignore rules may treat those differently. E.g. given the following gitignore file: * !/**/ we'd only want to unignore directories, while keeping files ignored. But still, calling `git_ignore_path_is_ignored("dir/")` will say that this directory is ignored because it treats "dir/" as a file path. As said, the `is_ignored` function cannot always decide whether the given path is a file or directory, and thus it may produce wrong results in some cases. While this is unfixable in the general case, we can do better when we are being passed a path name with a trailing path separator (e.g. "dir/") and always treat them as directories.

Patrick Steinhardt 8cf3fd93 2019-03-29T11:23:29 tests: config: assure that we can read symlinked global configuration According to reports, libgit2 is unable to read a global configuration file that is simply a symlink to the real configuration. Write a (succeeding) test that shows that libgit2 _is_ correctly able to do so.

Do so by writing the global configuration file and verifying that reading from it produces the expected values.

Patrick Steinhardt b3497344 2019-03-29T12:15:20 patch_parse: fix parsing addition/deletion of file with space The diff header format is a strange beast in that it is inherently unparseable in an unambiguous way. While parsing a/file.txt b/file.txt is obvious and trivially doable, parsing a diff header of a/file b/file ab.txt b/file b/file ab.txt is not (but in fact valid and created by git.git). Due to that, we have relaxed our diff header parser in commit 80226b5f6 (patch_parse: allow parsing ambiguous patch headers, 2017-09-22), so that we started to bail out when seeing diff headers with spaces in their file names. Instead, we try to use the "---" and "+++" lines, which are unambiguous. In some cases, though, we neither have a useable file name from the header nor from the "---" or "+++" lines. This is the case when we have a deletion or addition of a file with spaces: the header is unparseable and the other lines will simply show "/dev/null". This trips our parsing logic when we try to extract the prefix (the "a/" part) that is being used in the path line, where we unconditionally try to dereference a NULL pointer in such a scenario. We can fix this by simply not trying to parse the prefix in cases where we have no useable path name. That'd leave the parsed patch without either `old_prefix` or `new_prefix` populated. But in fact such cases are already handled by users of the patch object, which simply opt to use the default prefixes in that case.

Unfortunately, the tests do not clean up after themselves, which may cause subsequent tests to fail due to cruft left behind. Fix this by always removing created directories and their contents.

Edward Thomson 459ac856 2019-02-23T18:42:53 odb: provide a free function for custom backends Custom backends can allocate memory when reading objects and providing them to libgit2. However, if an error occurs in the custom backend after the memory has been allocated for the custom object but before it's returned to libgit2, the custom backend has no way to free that memory and it must be leaked. Provide a free function that corresponds to the alloc function so that custom backends have an opportunity to free memory before they return an error.
Edward Thomson 790aae77 2019-02-23T18:40:43 odb: rename git_odb_backend_malloc for consistency The `git_odb_backend_malloc` name is a system function that is provided for custom ODB backends and allows them to allocate memory for an ODB object in the read callback. This is important so that libgit2 can later free the memory used by an ODB object that was read from the custom backend. However, the name _suggests_ that it actually allocates a `git_odb_backend`. It does not; rename it to make it clear that it actually allocates backend _data_.

However, that syscall will fail when the file already exists. Thus, we must ignore the error code and simply let ftruncate extend the size of the file itself (albeit slowly). By calling ftruncate, we also need to prevent against file shrinkage, for compatibility with posix_ftruncate, which will only extend files, never shrink them.

Patrick Steinhardt 765ff6e0 2019-02-21T12:35:48 allocators: make crtdbg allocator reuse its own realloc In commit 6e0dfc6ff (Make stdalloc__reallocarray call stdalloc__realloc, 2019-02-16), we have changed the stdalloc allocator to reuse `stdalloc__realloc` to implement `stdalloc__reallocarray`. This commit is making the same change for the Windows-specific crtdbg allocator to avoid code duplication.
Patrick Steinhardt 48727e5d 2019-02-21T12:27:42 allocators: extract crtdbg allocator into its own file The Windows-specific crtdbg allocator is currently mixed into the crtdbg stacktracing compilation unit, making it harder to find than necessary. Extract it and move it into the new "allocators/" subdirectory to improve discoverability. This change means that the crtdbg compilation unit is now compiled unconditionally, whereas it has previously only been compiled on Windows platforms. Thus we now have additional guards around the code so that it will only be compiled if GIT_MSVC_CRTDBG is defined. This also allows us to move over the fallback-implementation of `git_win32_crtdbg_init_allocator` into the same compilation unit.
Patrick Steinhardt b63396b7 2019-02-21T12:13:59 allocators: move standard allocator into subdirectory Right now, our two allocator implementations are scattered around the tree in "stdalloc.h" and "win32/w32_crtdbg_stacktrace.h". Start grouping them together in a single directory "allocators/", similar to how e.g. our streams are organized.

For Visual Studio 2012 and earlier (ie, `_MSC_VER < 1800`), we do need to include `stdint.h` in our public headers, for types like `uint32_t`. Internally, we also need to define `PRId64` as a printf formatting string when it is not available.

Patrick Steinhardt 966b9440 2019-02-21T08:30:22 tests: apply: verify that we correctly truncate the source buffer Previously, we would fail to correctly truncate the source buffer if the source has more than one line and ends with a non-newline character. In the following call, we thus truncate the source string in the middle of the second line. Without the bug fixed, we would successfully apply the patch to the source and return success. With the overflow being fixed, we should return an error now.
Erik Aigner 014d4955 2019-02-20T15:30:11 apply: prevent OOB read when parsing source buffer When parsing the patch image from a string, we split the string by newlines to get a line-based view of it. To split, we use `memchr` on the buffer and limit the buffer length by the original length provided by the caller. This works just fine for the first line, but for every subsequent line we need to actually subtract the amount of bytes that we have already read. The above issue can be easily triggered by having a source buffer with at least two lines, where the second line does _not_ end in a newline. Given a string "foo\nb", we have an original length of five bytes. After having extracted the first line, we will point to 'b' and again try to `memchr(p, '\n', 5)`, resulting in an out-of-bounds read of four bytes. Fix the issue by correctly subtracting the amount of bytes already read.

Patrick Steinhardt 6a9117f5 2018-12-01T10:18:42 cache: use iteration interface for cache eviction To relieve us from memory pressure, we may regularly call `cache_evict_entries` to remove some entries from it. Unfortunately, our cache does not support a least-recently-used mode or something similar, which is why we evict entries completeley at random right now. Thing is, this is only possible due to the map interfaces exposing the entry indices, and we intend to completely remove those to decouple map users from map implementations. As soon as that is done, we are unable to do this random eviction anymore. Convert this to make use of an iterator for now. Obviously, there is no random eviction possible like that anymore, but we'll always start by evicting from the beginning of the map. Due to hashing, one may hope that the selected buckets will be evicted at least in some way unpredictably. But more likely than not, this will not be the case. But let's see what happens and if any users complain about degraded performance. If so, we might come up with a different scheme than random removal, e.g. by using an LRU cache.
Patrick Steinhardt c976b4f9 2018-12-01T10:18:26 indexer: use map iterator to delete expected OIDs To compute whether there are objects missing in a packfile, the indexer keeps around a map of OIDs that it still expects to see. This map does not store any values at all, but in fact the keys are owned by the map itself. Right now, we free these keys by iterating over the map and freeing the key itself, which is kind of awkward as keys are expected to be constant. We can make this a bit prettier by inserting the OID as value, too. As we already store the `NULL` pointer either way, this does not increase memory usage, but makes the code a tad more clear. Furthermore, we convert the previously existing map iteration via indices to make use of an iterator, instead.
Patrick Steinhardt 18cf5698 2018-12-01T09:37:40 maps: provide high-level iteration interface Currently, our headers need to leak some implementation details of maps due to their direct use of indices in the implementation of their foreach macros. This makes it impossible to completely hide the map structures away, and also makes it impossible to include the khash implementation header in the C files of the respective map only. This is now being fixed by providing a high-level iteration interface `map_iterate`, which takes as inputs the map that shall be iterated over, an iterator as well as the locations where keys and values shall be put into. For simplicity's sake, the iterator is a simple `size_t` that shall initialized to `0` on the first call. All existing foreach macros are then adjusted to make use of this new function.
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 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.
Patrick Steinhardt 8da93944 2018-12-01T10:52:44 idxmap: have `resize` functions return proper error code The currently existing function `git_idxmap_resize` and `git_idxmap_icase_resize` do not return any error codes at all due to their previous implementation making use of a macro. Due to that, it is impossible to see whether the resize operation might have failed due to an out-of-memory situation. Fix this by providing a proper error code. Adjust callers to make use of it.
Patrick Steinhardt 661fc57b 2018-12-01T01:16:25 idxmap: introduce high-level setter for key/value pairs Currently, one would use the function `git_idxmap_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_idxmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all callers of `git_idxmap_insert` to make use of it.
Patrick Steinhardt d00c24a9 2019-01-23T10:49:25 idxmap: 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 new high-level functions `git_idxmap_get` and `git_idxmap_icase_get` that take a map and a key and return 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 b9d0b664 2018-12-17T09:10:53 offmap: introduce high-level setter for key/value pairs Currently, there is only one caller that adds entries into an offset map, and this caller first uses `git_offmap_put` to add a key and then set the value at the returned index by using `git_offmap_set_value_at`. This is just too tighlty coupled with implementation details of the map as it exposes the index of inserted entries, which we really do not care about at all. Introduce a new function `git_offmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert the caller to make use of it instead.
Patrick Steinhardt aa245623 2018-11-30T18:28:05 offmap: 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.

Adjust all callers that can trivially be converted.
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.

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.
