Edward Thomson e1415dc3 2022-02-11T11:02:00 diff_file: test empty workdir file grows after obtaining a diff This test was also provided by @jorio https://github.com/libgit2/libgit2/pull/6208#issuecomment-1034072050
Iliyas Jorio 9aade20b 2022-02-09T19:04:52 diff_file: test workdir file becomes empty after obtaining a diff
Iliyas Jorio 0a0cd67d 2022-02-08T20:18:15 diff_file: fix crash if size of diffed file changes in workdir "diff_file_content_load_workdir_file()" maps a file from the workdir into memory. It uses git_diff_file.size to determine the size of the memory mapping. If this value goes stale, the mmaped area would be sized incorrectly. This could occur if an external program changes the contents of the file after libgit2 had cached its size. This used to segfault if the file becomes smaller (mmaped area too large). This patch causes diff_file_content_load_workdir_file to fail without crashing if it detects that the file size has changed.
Edward Thomson 11ef76a9 2022-01-22T13:31:02 index: use a byte array for checksum The index's checksum is not an object ID, so we should not use the `git_oid` type. Use a byte array for checksum calculation and storage. Deprecate the `git_index_checksum` function without a replacement. This is an abstraction that callers should not care about (and indeed do not seem to be using). Remove the unused `git_index__changed_relative_to` function.

Edward Thomson 4591e76a 2021-12-10T15:19:59 blob: identify binary content Introduce `git_blob_data_is_binary` to examine a blob's data, instead of the blob itself. A replacement for `git_buf_is_binary`.
Edward Thomson ca14942e 2021-11-11T13:28:08 tests: declare functions statically where appropriate
Edward Thomson 95117d47 2021-10-31T09:45:46 path: separate git-specific path functions from util Introduce `git_fs_path`, which operates on generic filesystem paths. `git_path` will be kept for only git-specific path functionality (for example, checking for `.git` in a path).
Edward Thomson f0e693b1 2021-09-07T17:53:49 str: introduce `git_str` for internal, `git_buf` is external libgit2 has two distinct requirements that were previously solved by `git_buf`. We require: 1. A general purpose string class that provides a number of utility APIs for manipulating data (eg, concatenating, truncating, etc). 2. A structure that we can use to return strings to callers that they can take ownership of. By using a single class (`git_buf`) for both of these purposes, we have confused the API to the point that refactorings are difficult and reasoning about correctness is also difficult. Move the utility class `git_buf` to be called `git_str`: this represents its general purpose, as an internal string buffer class. The name also is an homage to Junio Hamano ("gitstr"). The public API remains `git_buf`, and has a much smaller footprint. It is generally only used as an "out" param with strict requirements that follow the documentation. (Exceptions exist for some legacy APIs to avoid breaking callers unnecessarily.) Utility functions exist to convert a user-specified `git_buf` to a `git_str` so that we can call internal functions, then converting it back again.

We now allow transition from "file mode" state to "path" state directly if there is no "index", which will happen for patches adding or deleting files as demonstrated in added test case.

Patrick Steinhardt 17670ef2 2020-02-04T10:58:51 tests: diff: add test to verify behaviour with empty dir ordering It was reported that, given a file "abc.txt", a diff will be shown if an empty directory "abb/" is created, but not if "abd/" is created. Add a test to verify that we do the right thing here and do not depend on any ordering.
Patrick Steinhardt b0691db3 2020-01-31T09:39:12 tests: diff: verify that we are able to diff with empty subtrees While it is not allowed for a tree to have an empty tree as child (e.g. an empty directory), libgit2's tree builder makes it easy to create such trees. As a result, some applications may inadvertently end up with such an invalid tree, and we should try our best and handle them. One such case is when diffing two trees, where one of both trees has such an empty subtree. It was reported that this will cause our diff code to fail. While I wasn't able to reproduce this error, let's still add a test that verifies we continue to handle them correctly.
Gregory Herrero ece5bb5e 2019-11-07T14:10:00 diff: make patchid computation work with all types of commits. Current implementation of patchid is not computing a correct patchid when given a patch where, for example, a new file is added or removed. Some more corner cases need to be handled to have same behavior as git patch-id command. Add some more tests to cover those corner cases. Signed-off-by: Gregory Herrero <gregory.herrero@oracle.com>
Denis Laxalde 11de594f 2019-10-16T22:11:33 patch_parse: handle patches without extended headers Extended header lines (especially the "index <hash>..<hash> <mode>") are not required by "git apply" so it import patches. So we allow the from-file/to-file lines (--- a/file\n+++ b/file) to directly follow the git diff header. This fixes #5267.
Denis Laxalde b61810bf 2019-09-28T15:52:25 patch_parse: handle patches with new empty files Patches containing additions of empty files will not contain diff data but will end with the index header line followed by the terminating sequence "-- ". We follow the same logic as in cc4c44a and allow "-- " to immediately follow the index header.
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 658022c4 2019-07-18T13:53:41 configuration: cvar -> configmap `cvar` is an unhelpful name. Refactor its usage to `configmap` for more clarity.
Edward Thomson 5d92e547 2019-06-08T17:28:35 oid: `is_zero` instead of `iszero` The only function that is named `issomething` (without underscore) was `git_oid_iszero`. Rename it to `git_oid_is_zero` for consistency with the rest of the library.
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 e5090ee3 2018-10-04T11:19:28 diff_stats: use git's formatting of renames with common directories In cases where a file gets renamed such that the directories containing it previous and after the rename have a common prefix, then git will avoid printing this prefix twice and instead format the rename as "prefix/{old => new}". We currently didn't do anything like that, but simply printed "prefix/old -> prefix/new". Adjust our behaviour to instead match upstream. Adjust the test for this behaviour to expect the new format.
Patrick Steinhardt 3148efd2 2018-10-04T11:13:57 tests: verify diff stats with renames in subdirectory Until now, we didn't have any tests that verified that our format for renames in subdirectories is correct. While our current behaviour is no different than for renames that do not happen with a common prefix shared between old and new file name, we intend to change the format to instead match the format that upstream git uses. Add a test case for this to document our current behaviour and to show how the next commit will change that format.

Patrick Steinhardt 7db25870 2018-06-29T07:45:18 delta: fix sign-extension of big left-shift Our delta code was originally adapted from JGit, which itself adapted it from git itself. Due to this heritage, we inherited a bug from git.git in how we compute the delta offset, which was fixed upstream in 48fb7deb5 (Fix big left-shifts of unsigned char, 2009-06-17). As explained by Linus: Shifting 'unsigned char' or 'unsigned short' left can result in sign extension errors, since the C integer promotion rules means that the unsigned char/short will get implicitly promoted to a signed 'int' due to the shift (or due to other operations). This normally doesn't matter, but if you shift things up sufficiently, it will now set the sign bit in 'int', and a subsequent cast to a bigger type (eg 'long' or 'unsigned long') will now sign-extend the value despite the original expression being unsigned. One example of this would be something like unsigned long size; unsigned char c; size += c << 24; where despite all the variables being unsigned, 'c << 24' ends up being a signed entity, and will get sign-extended when then doing the addition in an 'unsigned long' type. Since git uses 'unsigned char' pointers extensively, we actually have this bug in a couple of places. In our delta code, we inherited such a bogus shift when computing the offset at which the delta base is to be found. Due to the sign extension we can end up with an offset where all the bits are set. This can allow an arbitrary memory read, as the addition in `base_len < off + len` can now overflow if `off` has all its bits set. Fix the issue by casting the result of `*delta++ << 24UL` to an unsigned integer again. Add a test with a crafted delta that would actually succeed with an out-of-bounds read in case where the cast wouldn't exist.

Stan Hu 9d83a2b0 2018-02-22T22:55:50 Sanitize the hunk header to ensure it contains UTF-8 valid data The diff driver truncates the hunk header text to 80 bytes, which can truncate 4-byte Unicode characters and introduce garbage characters in the diff output. This change sanitizes the hunk header before it is displayed. This mirrors the test in git: https://github.com/git/git/blob/master/t/t4025-hunk-header.sh Closes https://github.com/libgit2/rugged/issues/716

Patrick Steinhardt ce7080a0 2018-02-20T10:38:27 diff_tform: fix rename detection with rewrite/delete pair A rewritten file can either be classified as a modification of its contents or of a delete of the complete file followed by an addition of the new content. This distinction becomes important when we want to detect renames for rewrites. Given a scenario where a file "a" has been deleted and another file "b" has been renamed to "a", this should be detected as a deletion of "a" followed by a rename of "a" -> "b". Thus, splitting of the original rewrite into a delete/add pair is important here. This splitting is represented by a flag we can set at the current delta. While the flag is already being set in case we want to break rewrites, we do not do so in case where the `GIT_DIFF_FIND_RENAMES_FROM_REWRITES` flag is set. This can trigger an assert when we try to match the source and target deltas. Fix the issue by setting the `GIT_DIFF_FLAG__TO_SPLIT` flag at the delta when it is a rename target and `GIT_DIFF_FIND_RENAMES_FROM_REWRITES` is set.
Patrick Steinhardt 80e77b87 2018-02-20T10:03:48 tests: add rename-rewrite scenarios to "renames" repository Add two more scenarios to the "renames" repository. The first scenario has a major rewrite of a file and a delete of another file, the second scenario has a deletion of a file and rename of another file to the deleted file. Both scenarios will be used in the following commit.
Patrick Steinhardt d91da1da 2018-02-20T09:54:58 tests: diff::rename: use defines for commit OIDs While we frequently reuse commit OIDs throughout the file, we do not have any constants to refer to these commits. Make this a bit easier to read by giving the commit OIDs somewhat descriptive names of what kind of commit they refer to.
Patrick Steinhardt 2388a9e2 2017-12-15T10:47:01 diff_file: properly refcount blobs when initializing file contents When initializing a `git_diff_file_content` from a source whose data is derived from a blob, we simply assign the blob's pointer to the resulting struct without incrementing its refcount. Thus, the structure can only be used as long as the blob is kept alive by the caller. Fix the issue by using `git_blob_dup` instead of a direct assignment. This function will increment the refcount of the blob without allocating new memory, so it does exactly what we want. As `git_diff_file_content__unload` already frees the blob when `GIT_DIFF_FLAG__FREE_BLOB` is set, we don't need to add new code handling the free but only have to set that flag correctly.
Patrick Steinhardt cc4c44a9 2017-09-01T09:37:05 patch_parse: fix parsing patches only containing exact renames Patches which contain exact renames only will not contain an actual diff body, but only a list of files that were renamed. Thus, the patch header is immediately followed by the terminating sequence "-- ". We currently do not recognize this character sequence as a possible terminating sequence. Add it and create a test to catch the failure.
Patrick Steinhardt 89a34828 2017-06-16T13:34:43 diff: implement function to calculate patch ID The upstream git project provides the ability to calculate a so-called patch ID. Quoting from git-patch-id(1): A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a patch, with whitespace and line numbers ignored." Patch IDs can be used to identify two patches which are probably the same thing, e.g. when a patch has been cherry-picked to another branch. This commit implements a new function `git_diff_patchid`, which gets a patch and derives an OID from the diff. Note the different terminology here: a patch in libgit2 are the differences in a single file and a diff can contain multiple patches for different files. The implementation matches the upstream implementation and should derive the same OID for the same diff. In fact, some code has been directly derived from the upstream implementation. The upstream implementation has two different modes to calculate patch IDs, which is the stable and unstable mode. The old way of calculating the patch IDs was unstable in a sense that a different ordering the diffs was leading to different results. This oversight was fixed in git 1.9, but as git tries hard to never break existing workflows, the old and unstable way is still default. The newer and stable way does not care for ordering of the diff hunks, and in fact it is the mode that should probably be used today. So right now, we only implement the stable way of generating the patch ID.
Patrick Steinhardt c0eba379 2017-03-14T11:01:19 diff_parse: correctly set options for parsed diffs The function `diff_parsed_alloc` allocates and initializes a `git_diff_parsed` structure. This structure also contains diff options. While we initialize its flags, we fail to do a real initialization of its values. This bites us when we want to actually use the generated diff as we do not se the option's version field, which is required to operate correctly. Fix the issue by executing `git_diff_init_options` on the embedded struct.
Patrick Steinhardt ad5a909c 2017-03-14T09:39:37 patch_parse: fix parsing minimal trailing diff line In a diff, the shortest possible hunk with a modification (that is, no deletion) results from a file with only one line with a single character which is removed. Thus the following hunk @@ -1 +1 @@ -a + is the shortest valid hunk modifying a line. The function parsing the hunk body though assumes that there must always be at least 4 bytes present to make up a valid hunk, which is obviously wrong in this case. The absolute minimum number of bytes required for a modification is actually 2 bytes, that is the "+" and the following newline. Note: if there is no trailing newline, the assumption will not be offended as the diff will have a line "\ No trailing newline" at its end. This patch fixes the issue by lowering the amount of bytes required.
Patrick Steinhardt ace3508f 2017-03-14T10:37:47 patch_generate: fix `git_diff_foreach` only working with generated diffs The current logic of `git_diff_foreach` makes the assumption that all diffs passed in are actually derived from generated diffs. With these assumptions we try to derive the actual diff by inspecting either the working directory files or blobs of a repository. This obviously cannot work for diffs parsed from a file, where we do not necessarily have a repository at hand. Since the introduced split of parsed and generated patches, there are multiple functions which help us to handle patches generically, being indifferent from where they stem from. Use these functions and remove the old logic specific to generated patches. This allows re-using the same code for invoking the callbacks on the deltas.

Edward Thomson 92f7d32b 2015-09-12T13:46:22 diff::workdir: ensure ignored files are not returned Ensure that a diff with the workdir is not erroneously returning directories.
Edward Thomson d53c8880 2015-08-30T19:25:47 iterator: saner pathlist matching for idx iterator Some nicer refactoring for index iteration walks. The index iterator doesn't binary search through the pathlist space, since it lacks directory entries, and would have to binary search each index entry and all its parents (eg, when presented with an index entry of `foo/bar/file.c`, you would have to look in the pathlist for `foo/bar/file.c`, `foo/bar` and `foo`). Since the index entries and the pathlist are both nicely sorted, we walk the index entries in lockstep with the pathlist like we do for other iteration/diff/merge walks.
Edward Thomson 4a0dbeb0 2015-08-30T17:06:26 diff: use new iterator pathlist handling When using literal pathspecs in diff with `GIT_DIFF_DISABLE_PATHSPEC_MATCH` turn on the faster iterator pathlist handling. Updates iterator pathspecs to include directory prefixes (eg, `foo/`) for compatibility with `GIT_DIFF_DISABLE_PATHSPEC_MATCH`.
Edward Thomson 3273ab3f 2015-08-28T20:06:18 diff: better document GIT_DIFF_PATHSPEC_DISABLE Document that `GIT_DIFF_PATHSPEC_DISABLE` is not necessarily about explicit path matching, but also includes matching of directory names. Enforce this in a test.

Carlos Martín Nieto e451cd5c 2015-08-15T18:46:38 diff: don't error out on an invalid regex When parsing user-provided regex patterns for functions, we must not fail to provide a diff just because a pattern is not well formed. Ignore it instead.

Edward Thomson ba8fb7c4 2015-06-24T11:39:59 diff::binary tests: empty diff when forced binary Ensure that even when we're forcing a binary diff that we do not assume that there *is* a diff. There should be an empty diff for no change.
