Edward Thomson 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.
Edward Thomson 0db1c57c 2022-01-25T10:32:47 oid: add sha256 typed oids
Edward Thomson 0b068214 2021-12-11T15:34:27 oid: add functions to inspect oid information Provide helper functions to provide information about the object id size given its type.
Edward Thomson 61838295 2022-01-26T16:22:04 object: move oid header printing to object
Edward Thomson 0acaf3a8 2022-01-17T13:40:37 oid: define GIT_OID_SHA1_ZERO Callers should not assume the layout of the oid structure; provide them a macro that defines the null / zero sha1 object id.
Edward Thomson 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.
Edward Thomson b7a46fa8 2022-01-23T12:25:03 object: move oid header parsing to object
Edward Thomson cdff2f02 2022-06-13T21:34:01 repo: allow administrator to own the configuration Update our ownership checks that were introduced in libgit2 v1.4.3 (to combat CVE 2022-24765). These were not compatible with git's; git itself allows administrators to own the path. Our checks now match this behavior.

Edward Thomson 3a737169 2022-06-11T16:14:11 progress: fewer updates about throughput Avoid too much flashing on the console with updates about throughput. Only update throughput once a second.
Edward Thomson 286e7f0a 2022-06-11T16:08:28 cli: show progress on 32 bit machines
Colin Stolley 97954ee5 2022-05-20T09:06:50 Replace bitwise AND 0x7fffffff with XOR 0x80000000. Though both are correct, this makes it clear that we're dealing with the same value.
Colin Stolley 8a765c72 2022-05-19T16:33:57 midx: fix large object offset table check. It's insufficient to only check if the offset high order bit is set, we must also check to see if object_large_offsets are in use. This bug is causing objects to appear missing because they can't be found in the index.
John Alden 640e8a63 2022-05-17T11:01:43 fix missing error message
Carlos Martín Nieto a3f9617b 2022-05-03T14:09:40 midx: do not verify the checksum on load This is something we only want to do during explicit verification rather than on every load. Verifying does not seem like a big deal when we're running with test workloads but once your `multi-pack-index` reaches gigabytes, we spend more time hashing this than doing any work.
Carlos Martín Nieto 0f594445 2022-04-29T10:50:02 mwindow: use multiplication instesad of conditionals This is a very verbose way of performing a comparison where we already have the identity value with both signs. Instead of chainging several conditions, we can rely on the maths working out.
Carlos Martín Nieto 55c84333 2022-04-29T10:32:45 mwindow: include both the offset and the extra in the same call This makes it a bit easier to read while letting the caller specify how big the hash size is for this particular call.

lhchavez 1d88605c 2022-04-16T08:19:38 transport: introduce `git_transport_smart_remote_connect_options` 6fc6eeb66c40310086c8f059cae41de69ad4c6da removed `git_transport_smart_proxy_option`, and there was nothing added to replace it. That made it hard for custom transports / smart subtransports to know what remote connect options to use (e.g. proxy options). This change introduces `git_transport_smart_remote_connect_options` to replace it.
Edward Thomson 8a757ae2 2020-04-04T18:31:00 cli: introduce a clone command
Edward Thomson 7babe76f 2020-05-12T08:56:55 cli: introduce signal handler Provide a mechanism to add a signal handler for Unix or Win32.
Edward Thomson 48506f2b 2020-04-04T18:29:34 cli: introduce a progress class Provide a class that will display progress information to the console. Initially, it contains callbacks for fetch progress and checkout progress.
Edward Thomson 4161ebdd 2022-04-11T21:31:25 repo: make ownership checks optional Introduce the `GIT_OPT_SET_OWNER_VALIDATION` option, so that users can disable repository ownership validation.
Edward Thomson fa366921 2022-04-11T15:18:44 repo: honor safe.directory during ownership checks Obey the `safe.directory` configuration variable if it is set in the global or system configuration. (Do not try to load this from the repository configuration - to avoid malicious repositories that then mark themselves as safe.)
Edward Thomson f7f7e835 2022-04-11T13:04:26 repo: refactor global config loader function Pull the global configuration loader out of the symlink check so that it can be re-used.
Edward Thomson c0b7f88e 2022-04-11T17:06:55 fs_path: mock ownership checks Provide a mock for file ownership for testability.
Edward Thomson c0dfd1ad 2022-04-11T09:56:26 repo: ensure that repo dir is owned by current user Ensure that the repository directory is owned by the current user; this prevents us from opening configuration files that may have been created by an attacker.
Edward Thomson bf2620bc 2022-04-10T21:29:43 fs_path: refactor ownership checks into current user and system Provide individual file ownership checks for both the current user and the system user, as well as a combined current user and system user check.
Edward Thomson 71049b4a 2022-01-22T09:03:34 midx: use raw oid data A multi-pack index uses raw oid data, use a byte array to index into them.
Edward Thomson 41d4ac51 2022-01-22T08:49:06 index: use raw oid data The index contains entries with raw oid data, use a byte array for the raw entry data.
Edward Thomson 4fc3ce15 2022-01-22T07:46:41 pack: use raw oid data A packfile contains arrays of raw oid data, use a byte array to index into them.
Edward Thomson c2b3b0d8 2022-01-21T19:38:13 commit_graph: use raw oid data The commit graph contains arrays of raw oid data, use a byte array to index into them.
Edward Thomson 9ffa33a1 2022-01-22T08:48:43 oid: introduce `git_oid_raw_cpy` Now that oids are type-aware, they use their type to understand how many bytes to copy. Some callers may need to copy the raw bytes of the object id. This is equivalent to a memcpy that is a little more semantic.
Edward Thomson 6d8c7cab 2022-01-21T19:37:53 oid: introduce `git_oid_raw_ncmp`
Edward Thomson 526e8869 2022-01-21T19:17:40 oid: `hashcmp` is now `raw_cmp` We will talk about "raw" oids as untyped blobs of data; use a name for the comparison function that is in keeping with that.
Edward Thomson c569738c 2022-01-22T08:55:41 indexer: write raw id data Don't write the object id structure, write its raw oid data.
Edward Thomson 563751d1 2022-01-22T06:42:50 treecache: write the raw id not the object We explicitly want to write on the id data, not the beginning of the object data, which may contain other information in the future.
Edward Thomson 831e20ac 2022-01-22T06:39:38 oidmap: hash on the id, not the object We explicitly want to hash on the id data, not the beginning of the object data, which may contain other information in the future.
Edward Thomson 590ff981 2022-01-21T19:49:09 oid: don't assume the size of an oid Don't assume that a `git_oid` is a particular size; allocate `sizeof(git_oid)` instead.
Edward Thomson ab042161 2022-01-18T08:12:18 tree: move git_oid into tree entry A tree entry previously pointed directly into the object id within the tree object itself; this is useful to avoid any unnecessary memory copy (and an unnecessary use of 40 bytes per tree entry) but difficult if we change the underlying `git_oid` object to not simply be a raw object id but have additional structure. This commit moves the `git_oid` directly into the tree entry; this simplifies the tree entry creation from user data. We now copy the `git_oid` into place when parsing.

Edward Thomson cd8fde82 2022-04-05T22:40:28 Merge pull request #6258 from libgit2/ethomson/sha256_openssl_dynamic sha256: support dynamically loaded openssl
lhchavez 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!

Edward Thomson 0e30becc 2021-12-13T17:49:57 sha: cast nonsense for obnoxious gcc warnings gcc (mingw) warns when you cast the result of `GetProcAddress`; cast the results to `void *` before casting them to the actual result.
Edward Thomson ce78c83b 2021-12-13T15:31:21 sha: ensure we test both cng and cryptoapi on windows When GIT_SHA1_WIN32 or GIT_SHA256_WIN32 is used, ensure that we test both CryptoNG ("cng") and CryptoAPI.
Edward Thomson 6a7d5d23 2021-12-13T11:54:49 sha: support Win32 for SHA256 Adding SHA256 support prompted an overdue refactoring of some of the unnecessary complexity around the CNG/CryptoAPI abstraction.

Edward Thomson 83c27786 2021-12-12T15:14:21 sha: support CommonCrypto for SHA256
Edward Thomson b900981c 2021-12-12T14:25:25 sha: add sha256 algorithm Add support for a SHA256 hash algorithm, and add the "builtin" SHA256 hash engine (from RFC 6234).
Edward Thomson 36df49c2 2021-12-12T14:29:11 sha: GIT_ERROR_SHA1 is deprecated in favor of GIT_ERROR_SHA The more generic GIT_ERROR_SHA allows for SHA256 errors as well as SHA1.
Edward Thomson c7b189ba 2021-12-12T13:19:36 sha1: refactor folder structure Eliminate the `sha1` folder, move it down into `hash` so that future impelmentations can share common code.
Edward Thomson 8bc998f4 2021-12-12T12:44:13 sha1: remove generic implementation Remove the "generic" implementation; it should never be used; it only existed for a no-dependencies configuration, and our bundled sha1dc satisfies that requirement _and_ is correct.
Edward Thomson a9a7967a 2022-03-22T22:16:57 fetch: support OID refspec without dst Support the ability to create a refspec that is a single object ID without a destination.
Wilhelm Bierbaum ecc722c3 2022-03-16T10:25:11 Fix a string parsing bug when validating extensions from the configuration As builtin extensions are evaluated in the latter half of `check_valid_extension`, a string `cfg` is concatenated with the static string 'extension.' and the value from `builtin_extension`, before being compared with the configured value. This string is not being cleared while iterating through the names of the extensions. Because there is currently only one extension ('noop'), the bug was never noticible. This patch corrects the behavior by clearing the string on each iteration, as is done in the first block.
Iliyas Jorio d427f952 2022-03-13T17:40:54 diff_delta_format_path: handle null filename This fixes a crash in test cases test_diff_parse__new_file_with_space_and_regenerate_patch and test_diff_parse__delete_file_with_space_and_regenerate_patch
Edward Thomson 073e63d0 2022-02-27T10:05:24 object: validate that `odb_obj` was set
Edward Thomson 241d838f 2022-02-27T10:02:05 http: skip processing when body is null or 0 length Mistakenly `&&` when we should have `||`d.
Edward Thomson 9f0088c4 2022-02-27T09:26:16 fs_path: exit quickly in `dirname_r` failure When we encounter a situation where we need to exit, simply `return -1` instead of trying to set `len = -1` and then jumping to the exit handler, which would erroneously do work based on the `len` value.
Edward Thomson 043a87a0 2022-02-27T09:21:53 refdb: unlock mutex on assertion failure If we're safely asserting (and returning an error to the caller), we should still unlock our mutex.
Edward Thomson d9b041e6 2022-02-27T09:20:58 assert: add `ASSERT_WITH_CLEANUP` Now that we safely assert and return, we may need to be in a place where we need to unlock mutexes or cleanup resources. Provide `ASSERT_WITH_CLEANUP` that permits for this behavior by taking a block.
Edward Thomson e32db9f2 2022-02-27T08:54:09 cli: always give a value to `error`
Edward Thomson e427d0a1 2021-11-30T10:33:24 cli: add `hash-object` command Introduce a simple command that emulates `git hash-object`.
Edward Thomson dcabef22 2022-02-21T13:06:43 futils: produce improved error messages
Edward Thomson e7be6b76 2021-11-29T12:04:06 futils: provide an option to read a whole file by fd
Edward Thomson b8771227 2021-11-28T10:32:03 cli: add `cat-file` command Introduce a simple command that emulates `git cat-file`.
Edward Thomson f8e7d8fd 2021-11-26T17:33:38 cli: support `help <command>` Support `help <command>` by re-invoking the command itself with the `--help` argument. This allows us to keep the help logic with the commands itself.
Edward Thomson c6dd82d9 2020-02-23T11:54:33 cli: introduce a help command Add a framework for commands to be defined, and add our first one, "help". When `git2_cli help` is run, the `cmd_help` function will be invoked with the remaining command line arguments. This allows users to invoke `git2_cli help foo` to get information about the `foo` subcommand.
Edward Thomson 8526cbd5 2021-11-26T09:37:29 opt: use a custom function to print usage Our argument parser (https://github.com/ethomson/adopt) includes a function to print a usage message based on the allowed options. Omit this and use a cutom function that understands that we have subcommands ("checkout", "revert", etc) that each have their own options.
Edward Thomson 3a3ab065 2020-05-03T23:13:28 cli: infrastructure for a cli project Introduce a command-line interface for libgit2. The goal is for it to be git-compatible. 1. The libgit2 developers can more easily dogfood libgit2 to find bugs, and performance issues. 2. There is growing usage of libgit2's examples as a client; libgit2's examples should be exactly that - simple code samples that illustrate libgit2's usage. This satisfies that need directly. 3. By producing a client ourselves, we can better understand the needs of client creators, possibly producing a shared "middleware" for commonly-used pieces of client functionality like interacting with external tools. 4. Since git is the reference implementation, we may be able to benefit from git's unit tests, running their test suite against our CLI to ensure correct behavior. This commit introduces a simple infrastructure for the CLI. The CLI is currently links libgit2 statically; this is because the utility layer is required for libgit2 _but_ shares the error state handling with libgit2 itself. There's no obviously good solution here without introducing annoying indirection or more complexity. Until we can untangle that dependency, this is a good step forward. In the meantime, we link the libgit2 object files, but we do not include the (private) libgit2 headers. This constrains the CLI to the public libgit2 interfaces.
Edward Thomson 3344fddc 2021-11-16T23:29:22 refactor: `tests` is now `tests/libgit2` Like we want to separate libgit2 and utility source code, we want to separate libgit2 and utility tests. Start by moving all the tests into libgit2.
Edward Thomson 91ba0896 2021-11-15T09:54:00 cmake: rename git2internal target to libgit2 The `git2internal` target is actually the git library; call it such so that IDE users have visibility into it.
Edward Thomson d7b49ed4 2021-11-15T14:54:17 cmake: remove unnecessary xcode hack
Edward Thomson 5fcfada5 2021-11-15T07:45:16 cmake: document CMakeLists.txt hierarchy
Edward Thomson c3b7ace9 2021-11-14T16:43:53 refactor: make util an object library Instead of simply including the utility files directly, make them a cmake object library for easy reusability between other projects within libgit2. Now the top-level `src` is responsible for platform selection, while the next-level `libgit2` and `util` configurations are responsible for identifying what objects they include.
Edward Thomson ef4ab298 2021-11-14T08:47:40 refactor: `src` is now `src/libgit2`
Edward Thomson 49e180c8 2022-02-15T22:55:48 errors: expose `git_error_set` The `git_error_set` function is useful for callers who implement backends and advanced callbacks. Expose it.
Edward Thomson c716b9f2 2022-02-21T10:16:05 odb: initialize `object` before use Newer gcc is complaining about `object` being potentially not initialized; initialize it.
Edward Thomson eca9e1cf 2022-02-22T07:17:12 Merge pull request #6228 from libgit2/ethomson/win32_systemdirs win32: `find_system_dirs` does not return `GIT_ENOTFOUND`
Edward Thomson f45121ed 2022-02-21T16:13:52 win32: `find_system_dirs` does not return `GIT_ENOTFOUND` Allow for no Git for Windows installation. When there is no GfW found in the path or registry, `git_win32__find_system_dirs` would return a `GIT_ENOTFOUND`. Callers were not expecting this. Since this is no error, we simply return `0` so that callers can move on with their lives.
Carlos Martín Nieto 15860aa0 2022-02-21T10:03:06 remote: do store the update_tips callback error value We use `git_error_set_after_callback_function` to determine whether `update_tips` returned an error but do not store its return value making us think it always returns 0. Fix it by adding the common patter of storing it inside the `if` when calling it.

Edward Thomson b722c45d 2022-02-17T13:55:34 xdiff: use xdl_free not free We've added a lovely abstraction layer in xdiff so that it can call our allocation functions. But it also needs to call our free functions. We missed some `free` calls in `xmerge.c`. Update them to use `xdl_free`. Without this, we will pass a pointer allocated with a custom allocator to the system free function. :bomb:
