3fbf580c	2022-01-23T09:47:01	oid: give oids a type `git_oid`s now have a type, and we require the oid type when creating the object id from creation functions.
dbc4ac1c	2022-01-22T23:10:03	oid: `GIT_OID_SZ` is now `GIT_OID_SHA1_SIZE` In preparation for SHA256 support, `GIT_OID_RAWSZ` and `GIT_OID_HEXSZ` need to indicate that they're the size of _SHA1_ OIDs.

33b1d3fd	2022-04-05T13:10:33	[midx] Fix an undefined behavior (left-shift signed overflow) There was a missing check to ensure that the `off64_t` (which is a signed value) didn't overflow when parsing it from the midx file. This shouldn't have huge repercusions since the parsed value is immediately validated afterwards, but then again, there is no such thing as "benign" undefined behavior. This change makes all the bitwise arithmetic happen with unsigned types and is only casted to `off64_t` until the very end. Thanks to Taotao Gu for finding and reporting this!

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.

25b75cd9	2021-03-10T07:06:15	commit-graph: Create `git_commit_graph` as an abstraction for the file This change does a medium-size refactor of the git_commit_graph_file and the interaction with the ODB. Now instead of the ODB owning a direct reference to the git_commit_graph_file, there will be an intermediate git_commit_graph. The main advantage of that is that now end users can explicitly set a git_commit_graph that is eagerly checked for errors, while still being able to lazily use the commit-graph in a regular ODB, if the file is present.
1f32ed25	2021-01-04T19:33:48	commit-graph: Support lookups of entries in a commit-graph This change introduces `git_commit_graph_entry_find()` and `git_commit_graph_entry_parent()`. These two functions allow a much faster lookup of commits by ID, since the ODB does not need to be consulted, the commit object does not need to be inflated, and the contents of the commit object do not need to be parsed.

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.

69055813	2019-06-28T10:50:01	fuzzers: make printf formatters cross-platform compatible The `printf` formatters in our standalone fuzzing driver are currently using the "%m" specifier, which is a GNU extension that prints the error message for the error code in `errno`. As we're using libgit2 functions in both cases anyway, let's just use `git_error_last` instead to make this valid on all platforms.

6956a954	2018-10-11T12:26:44	fuzzers: initialize libgit2 in standalone driver The standalone driver for libgit2's fuzzing targets makes use of functions from libgit2 itself. While this is totally fine to do, we need to make sure to always have libgit2 initialized via `git_libgit2_init` before we call out to any of these. While this happens in most cases as we call `LLVMFuzzerInitialize`, which is provided by our fuzzers and which right now always calls `git_libgit2_init`, one exception to this rule is our error path when not enough arguments have been given. In this case, we will call `git_vector_free_deep` without libgit2 having been initialized. As we did not set up our allocation functions in that case, this will lead to a segmentation fault. Fix the issue by always initializing and shutting down libgit2 in the standalone driver. Note that we cannot let this replace the initialization in `LLVMFuzzerInitialize`, as it is required when using the "real" fuzzers by LLVM without our standalone driver. It's no problem to call the initialization and deinitialization functions multiple times, though.

e38ddc90	2018-07-26T15:41:41	fuzzers: limit maximum pack object count By default, libgit2 allows up to 2^32 objects when downloading a packfile from a remote. For each of these objects, libgit2 will allocate up to two small structs, which in total adds up to quite a lot of memory. As a result, our fuzzers might run out of memory rather quick in case where they receive as input a packfile with such a huge count of objects. Limit the packfile object count to 10M objects. This is sufficiently big to still work with most largish repos (linux.git has around 6M objects as of now), but small enough to not cause the fuzzer to OOM.
5db64e2f	2018-07-19T14:52:02	fuzzers: convert download_refs fuzzer to C Convert the "download_refs" fuzzer from C++ to C. Rename the source file to have it be picked up by our build system.
730c0edb	2018-07-19T14:21:35	fuzzers: import download_refs fuzzer from oss-fuzz This is a direct copy of the code from google/oss-fuzz, written by Nelson Elhage (@nelhage). Note that due to the ".cc" ending, the file will not yet be picked up by the build system. This is intended, as currently that file is partly written in C++, requiring a conversion to C.
de53972f	2018-07-20T11:07:47	fuzzers: avoid use of libgit2 internals in packfile_raw The packfile_raw fuzzer is using some internal APIs from libgit2, which makes it hard to compile it as part of the oss-fuzz project. As oss-fuzz requires us to link against the C++ FuzzingEngine library, we cannot use "-DBUILD_FUZZERS=ON" directly but instead have to first compile an object from our fuzzers and then link against the C++ library. Compiling the fuzzer objects thus requires an external invocation of CC, and we certainly don't want to do further black magic by adding libgit2's private source directory to the header include path. To fix the issue, convert the code to not use any internal APIs. Besides some headers which we have to add now, this also requires us to change to the hashing function of the ODB. Note that this will change the hashing result, as we have previously not prepended the object header to the data that is to be hashed. But this shouldn't matter in practice, as we don't care for the hash value anyway.
bf3382d5	2018-07-19T15:22:18	cmake: remove need to add "-fsanitize=fuzzer" flag for fuzzers Right now, users are being instrucded to add the "-DCMAKE_EXE_LINKER_FLAGS=-fsanitize=fuzzer" flag when they want to build our fuzzers. This is error-prone and user unfriendly. Instead, just add the flag to our fuzzers' build instructions so that it happens automatically. Adjust the README accordingly.
07cf8b38	2018-07-20T09:03:10	cmake: use C90 standard for our fuzzing targets Like all our other internal code, we want to force the use of C90 for our fuzzers. Do so by setting the "C_STANDARD" property of our fuzzing targets.

Rename the directory to be called "fuzzers" instead. Furthermore, we rename the fuzzer "fuzz_packfile_raw" to "packfile_raw_fuzzer", which is also in line with the already existing fuzzer at google/oss-fuzz. While at it, rename the "packfile_raw" fuzzer to instead just be called "packfile" fuzzer.

While this happens in most cases as we call `LLVMFuzzerInitialize`, which is provided by our fuzzers and which right now always calls `git_libgit2_init`, one exception to this rule is our error path when not enough arguments have been given. In this case, we will call `git_vector_free_deep` without libgit2 having been initialized. As we did not set up our allocation functions in that case, this will lead to a segmentation fault. Fix the issue by always initializing and shutting down libgit2 in the standalone driver. Note that we cannot let this replace the initialization in `LLVMFuzzerInitialize`, as it is required when using the "real" fuzzers by LLVM without our standalone driver. It's no problem to call the initialization and deinitialization functions multiple times, though.

fuzzers: limit maximum pack object count By default, libgit2 allows up to 2^32 objects when downloading a packfile from a remote. For each of these objects, libgit2 will allocate up to two small structs, which in total adds up to quite a lot of memory. As a result, our fuzzers might run out of memory rather quick in case where they receive as input a packfile with such a huge count of objects. Limit the packfile object count to 10M objects. This is sufficiently big to still work with most largish repos (linux.git has around 6M objects as of now), but small enough to not cause the fuzzer to OOM.

fuzzers: import download_refs fuzzer from oss-fuzz This is a direct copy of the code from google/oss-fuzz, written by Nelson Elhage (@nelhage). Note that due to the ".cc" ending, the file will not yet be picked up by the build system. This is intended, as currently that file is partly written in C++, requiring a conversion to C.

fuzzers: avoid use of libgit2 internals in packfile_raw The packfile_raw fuzzer is using some internal APIs from libgit2, which makes it hard to compile it as part of the oss-fuzz project. As oss-fuzz requires us to link against the C++ FuzzingEngine library, we cannot use "-DBUILD_FUZZERS=ON" directly but instead have to first compile an object from our fuzzers and then link against the C++ library. Compiling the fuzzer objects thus requires an external invocation of CC, and we certainly don't want to do further black magic by adding libgit2's private source directory to the header include path. To fix the issue, convert the code to not use any internal APIs. Besides some headers which we have to add now, this also requires us to change to the hashing function of the ODB. Note that this will change the hashing result, as we have previously not prepended the object header to the data that is to be hashed. But this shouldn't matter in practice, as we don't care for the hash value anyway.

cmake: remove need to add "-fsanitize=fuzzer" flag for fuzzers Right now, users are being instrucded to add the "-DCMAKE_EXE_LINKER_FLAGS=-fsanitize=fuzzer" flag when they want to build our fuzzers. This is error-prone and user unfriendly. Instead, just add the flag to our fuzzers' build instructions so that it happens automatically. Adjust the README accordingly.

cmake: use C90 standard for our fuzzing targets Like all our other internal code, we want to force the use of C90 for our fuzzers. Do so by setting the "C_STANDARD" property of our fuzzing targets.

fuzzers: rename "fuzz" directory to match our style Our layout uses names like "examples" or "tests" which is why the "fuzz" directory doesn't really fit in here. Rename the directory to be called "fuzzers" instead. Furthermore, we rename the fuzzer "fuzz_packfile_raw" to "packfile_raw_fuzzer", which is also in line with the already existing fuzzer at google/oss-fuzz. While at it, rename the "packfile_raw" fuzzer to instead just be called "packfile" fuzzer.
