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 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 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 9937967e 2021-08-29T21:29:14 Merge branch 'main' into http-use-eauth
Edward Thomson abe2efe1 2019-12-09T12:37:34 Introduce GIT_ASSERT macros Provide macros to replace usages of `assert`. A true `assert` is punishing as a library. Instead we should do our best to not crash. GIT_ASSERT_ARG(x) will now assert that the given argument complies to some format and sets an error message and returns `-1` if it does not. GIT_ASSERT(x) is for internal usage, and available as an internal consistency check. It will set an error message and return `-1` in the event of failure.

Edward Thomson 647dfdb4 2019-01-10T22:13:07 git_error: deprecate error values Replace the `GITERR` values with a `const int` to deprecate error values.
Edward Thomson 20961b98 2018-12-26T14:06:21 git_error: use full class name in public error API Move to the `git_error` name in error-related functions, deprecating the `giterr` functions. This means, for example, that `giterr_last` is now `git_error_last`. The old names are retained for compatibility. This only updates the public API; internal API and function usage remains unchanged.
Edward Thomson a2e6e0ea 2018-11-06T14:15:43 transport: allow cred/cert callbacks to return GIT_PASSTHROUGH Allow credential and certificate checking callbacks to return GIT_PASSTHROUGH, indicating that they do not want to act. Introduce this to support in both the http and ssh callbacks. Additionally, enable the same mechanism for certificate validation. This is most useful to disambiguate any meaning in the publicly exposed credential and certificate functions (`git_transport_smart_credentials` and `git_transport_smart_certificate_check`) but it may be more generally useful for callers to be able to defer back to libgit2.
Edward Thomson c3077ea0 2018-06-25T21:24:49 apply: return a specific exit code on failure Return `GIT_EAPPLYFAIL` on patch application failure so that users can determine that patch application failed due to a malformed/conflicting patch by looking at the error code.

Patrick Steinhardt 28a0741f 2017-04-10T09:30:08 odb: verify object hashes The upstream git.git project verifies objects when looking them up from disk. This avoids scenarios where objects have somehow become corrupt on disk, e.g. due to hardware failures or bit flips. While our mantra is usually to follow upstream behavior, we do not do so in this case, as we never check hashes of objects we have just read from disk. To fix this, we create a new error class `GIT_EMISMATCH` which denotes that we have looked up an object with a hashsum mismatch. `odb_read_1` will then, after having read the object from its backend, hash the object and compare the resulting hash to the expected hash. If hashes do not match, it will return an error. This obviously introduces another computation of checksums and could potentially impact performance. Note though that we usually perform I/O operations directly before doing this computation, and as such the actual overhead should be drowned out by I/O. Running our test suite seems to confirm this guess. On a Linux system with best-of-five timings, we had 21.592s with the check enabled and 21.590s with the ckeck disabled. Note though that our test suite mostly contains very small blobs only. It is expected that repositories with bigger blobs may notice an increased hit by this check. In addition to a new test, we also had to change the odb::backend::nonrefreshing test suite, which now triggers a hashsum mismatch when looking up the commit "deadbeef...". This is expected, as the fake backend allocated inside of the test will return an empty object for the OID "deadbeef...", which will obviously not hash back to "deadbeef..." again. We can simply adjust the hash to equal the hash of the empty object here to fix this test.
Edward Thomson cc8d9a29 2017-04-01T10:44:17 win32: introduce `do_with_retries` macro Provide a macro that will allow us to run a function with posix-like return values multiple times in a retry loop, with an optional cleanup function called between invocations.

Edward Thomson 7cb904ba 2014-04-01T23:58:59 Introduce git_apply_patch The beginnings of patch application from an existing (diff-created) git_patch object: applies the hunks of a git_patch to a buffer.
Edward Thomson cd59e0c0 2016-02-23T13:05:49 giterr_set_str: remove `GITERR_OS` documentation The `giterr_set_str` does not actually honor `GITERR_OS`. Remove the documentation that claims that we do.

Edward Thomson 885b94aa 2015-05-28T15:26:13 Rename GIT_EMERGECONFLICT to GIT_ECONFLICT We do not error on "merge conflicts"; on the contrary, merge conflicts are a normal part of merging. We only error on "checkout conflicts", where a change exists in the index or the working directory that would otherwise be overwritten by performing the checkout. This *may* happen during merge (after the production of the new index that we're going to checkout) but it could happen during any checkout.
Carlos Martín Nieto 1396c381 2015-05-18T16:04:55 errors: add GIT_EEOF to indicate early EOF This can be used by tools to show mesages about failing to communicate with the server. The error message in this case will often contain the server's error message, as far as it managed to send anything.

Carlos Martín Nieto 753e17b0 2014-11-19T18:42:29 peel: reject bad queries with EINVALIDSPEC There are some combination of objects and target types which we know cannot be fulfilled. Return EINVALIDSPEC for those to signify that there is a mismatch in the user-provided data and what the object model is capable of satisfying. If we start at a tag and in the course of peeling find out that we cannot reach a particular type, we return EPEEL.

Russell Belfer 373cf6a9 2013-12-09T10:17:47 Update docs for new callback return value behavior
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.

Vicent Marti 1eab9f0e 2013-11-05T14:56:10 error: Simplify giterr_detach
Russell Belfer d6c60169 2013-11-04T15:45:31 Add giterr_detach API to get and clear error There are a number of cases where it is convenient to be able to fetch and "claim" the current error string, clearing the error. This is helpful when you need to call some code that may alter the error and you want to restore it later on and/or report it via some other mechanism.
Russell Belfer 974774c7 2013-09-09T16:57:34 Add attributes to filters and fix registry The filter registry as implemented was too primitive to actually work once multiple filters were coming into play. This expands the implementation of the registry to handle multiple prioritized filters correctly. Additionally, this adds an "attributes" field to a filter that makes it really really easy to implement filters that are based on one or more attribute values. The lookup and even simple value checking can all happen automatically without custom filter code. Lastly, with the registry improvements, this fills out the filter lifecycle callbacks, with initialize and shutdown callbacks that will be called before the filter is first used and after it is last invoked. This allows for system-wide initialization and cleanup by the filter.
Vicent Martí efc9e670 2013-09-17T03:45:35 Merge pull request #1856 from libgit2/cmn/no-orphans No such thing as an orphan branch
Carlos Martín Nieto 605da51a 2013-09-17T09:50:30 No such thing as an orphan branch Unfortunately git-core uses the term "unborn branch" and "orphan branch" interchangeably. However, "orphan" is only really there for the checkout command, which has the `--orphan` option so it doesn't actually create the branch. Branches never have parents, so the distinction of a branch with no parents is odd to begin with. Crucially, the error messages deal with unborn branches, so let's use that.

Russell Belfer ad9a921b 2012-11-08T17:05:07 Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.

Russell Belfer f335ecd6 2012-08-30T14:24:16 Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.
Russell Belfer aa13bf05 2012-08-02T13:00:58 Major submodule rewrite This replaces the old submodule API with a new extended API that supports most of the things that can be done with `git submodule`.
Russell Belfer 5dca2010 2012-08-03T17:08:01 Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

Russell Belfer 7c7ff7d1 2012-03-19T16:10:11 Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.
Russell Belfer e3c47510 2012-03-13T14:23:24 Resolve comments from pull request This converts the map validation function into a macro, tweaks the GITERR_OS system error automatic appending, and adds a tentative new error access API and some quick unit tests for both the old and new error APIs.
Russell Belfer e1de726c 2012-03-12T22:55:40 Migrate ODB files to new error handling This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.
Vicent Martí dda708e7 2012-03-09T19:55:50 error-handling: On-disk config file backend Includes: - Proper error reporting when encountering syntax errors in a config file (file, line number, column). - Rewritten `config_write`, now with 99% less goto-spaghetti - Error state in `git_filebuf`: filebuf write functions no longer need to be checked for error returns. If any of the writes performed on a buffer fail, the last call to `git_filebuf_commit` or `git_filebuf_hash` will fail accordingly and set the appropiate error message. Baller!
