Patrick Steinhardt 9703d26f 2020-06-29T12:22:27 tests: reflog: remove unused signature There's two tests that create a commit signature, but never make any use of it. Let's remove these to avoid any confusion.
Patrick Steinhardt 1f39593b 2020-06-30T08:53:59 refdb: extract function to check whether to append HEAD to the reflog The logic to determine whether a reflog entry should be for the HEAD reference is non-trivial. Currently, the only user of this is the filesystem-based refdb, but with the advent of the reftable refdb we're going to add a second user that's interested in having the same behaviour. Let's pull out a new function that checks whether a given reference should cause a entry to be written to the HEAD reflog as a preparatory step.

Alexander Ovchinnikov 5c40456b 2020-06-16T13:19:02 Enable building git2.rc resource script with GCC
lhchavez 7c964416 2020-06-30T05:46:47 Make NTLMClient Memory and UndefinedBehavior Sanitizer-clean This change makes the code pass the libgit2 tests cleanly when MSan/UBSan are enabled. Notably: * Changes malloc/memset combos into calloc for easier auditing. * Makes `write_buf` return early if the buffer length is empty to avoid arithmetic with NULL pointers (which UBSan does not like). * Initializes a few arrays that were sometimes being read before being written to.
lhchavez 3a197ea7 2020-06-27T12:33:32 Make the tests pass cleanly with MemorySanitizer This change: * Initializes a few variables that were being read before being initialized. * Includes https://github.com/madler/zlib/pull/393. As such, it only works reliably with `-DUSE_BUNDLED_ZLIB=ON`.
lhchavez d0656ac8 2020-06-27T12:15:26 Make the tests run cleanly under UndefinedBehaviorSanitizer This change makes the tests run cleanly under `-fsanitize=undefined,nullability` and comprises of: * Avoids some arithmetic with NULL pointers (which UBSan does not like). * Avoids an overflow in a shift, due to an uint8_t being implicitly converted to a signed 32-bit signed integer after being shifted by a 32-bit signed integer. * Avoids a unaligned read in libgit2. * Ignores unaligned reads in the SHA1 library, since it only happens on Intel processors, where it is _still_ undefined behavior, but the semantics are moderately well-understood. Of notable omission is `-fsanitize=integer`, since there are lots of warnings in zlib and the SHA1 library which probably don't make sense to fix and I could not figure out how to silence easily. libgit2 itself also has ~100s of warnings which are mostly innocuous (e.g. use of enum constants that only fit on an `uint32_t`, but there is no way to do that in a simple fashion because the data type chosen for enumerated types is implementation-defined), and investigating whether there are worrying warnings would need reducing the noise significantly.

Patrick Steinhardt 6256d023 2020-06-15T14:34:29 diff_print: adjust code to match current coding style
Patrick Steinhardt 490d0c9c 2020-06-15T14:26:13 diff_print: return out-of-memory situation when printing binary We currently don't check for out-of-memory situations on exiting `format_binary` and, as a result, may return a partially filled buffer. Fix this by checking the buffer via `git_buf_oom`.
Patrick Steinhardt bea5fd9f 2020-06-15T13:26:18 diff_print: do not call abort(3P) Calling abort(3P) in a library is rather rude and shouldn't happen, as we effectively prohibit any corrective actions made by the application linking to it. We thus shouldn't call it at all, but instead use our new `GIT_ASSERT` macros. Remove the call to abort(3P) in case a diff delta has an unexpected type to fix this.
Patrick Steinhardt 0cf1f444 2020-06-15T13:19:44 diff_print: handle errors when printing to file When printing the diff to a `FILE *` handle, we neither check the return value of fputc(3P) nor the one of fwrite(3P). As a result, we'll silently return successful even if we didn't print anything at all. Futhermore, the arguments to fwrite(3P) are reversed: we have one item of length `content_len`, and not `content_len` items of one byte. Fix both issues by checking return values as well as reversing the arguments to fwrite(3P).
Edward Thomson d60bf002 2020-06-16T17:02:40 Merge pull request #5550 from libgit2/ethomson/github_actions Introduce CI with GitHub Actions
Edward Thomson 47fb33ba 2020-06-07T00:39:27 Introduce CI with GitHub Actions Add CI using GitHub Actions and GitHub Packages: * This moves our Linux build containers into GitHub Packages; we will identify the most recent commit that updated the docker descriptions, and then look for a docker image in libgit2's GitHub Packages registry for a container with the tag corresponding to that description. If there is not one, we will build the container and then push it to GitHub Packages. * We no longer need to manage authentication with our own credentials or PAT tokens. GitHub Actions provides a GITHUB_TOKEN that can publish artifacts, packages and commits to our repository within a workflow run. * We will use a matrix to build our various CI steps. This allows us to keep configuration in a single place without multiple YAML files.

Edward Thomson 4852d8da 2020-06-10T22:18:13 docker: don't take BASE as an argument The xenial image depends on ubuntu:xenial; the bionic one on ubuntu:bionic. No need for this to be a variable, that's just additional (unnecessary) state to manage in the CI setup(s).
Edward Thomson 8b8b69a7 2020-06-10T22:13:25 azure pipelines: use bundled zlib Azure Pipelines has a version of zlib hanging out on the filesystem; avoid trying to use it as it's either 64 _or_ 32 bit, so exactly one of our builds will fail.
Patrick Steinhardt 96a5f38f 2020-06-10T07:42:52 Merge pull request #5551 from pks-t/pks/missing-declarations Missing declarations
Patrick Steinhardt 03c4f86c 2020-06-08T12:42:59 cmake: enable warnings for missing function declarations Over time, we have accumulated quite a lot of functions with missing prototypes, missing `static` keywords or which were completely unused. It's easy to miss these mistakes, but luckily GCC and Clang both have the `-Wmissing-declarations` warning. Enabling this will cause them to emit warnings for every not-static function that doesn't have a previous declaration. This is a very sane thing to enable, and with the preceding commits all these new warnings have been fixed. So let's always enable this warning so we won't introduce new instances of them.
Patrick Steinhardt fd1f0940 2020-06-08T12:42:26 refs: add missing function declaration The function `git_reference__is_note` is not declared anywhere. Let's add the declaration to avoid having non-static functions without declaration.
Patrick Steinhardt c6184f0c 2020-06-08T21:07:36 tree-wide: do not compile deprecated functions with hard deprecation When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.
Patrick Steinhardt 6e1efcd6 2020-06-08T12:46:04 tree-wide: add missing header includes We're missing some header includes leading to missing function prototypes. While we currently don't warn about these, we should have their respective headers included in order to detect the case where a function signature change results in an incompatibility.
Patrick Steinhardt a6c9e0b3 2020-06-08T12:40:47 tree-wide: mark local functions as static We've accumulated quite some functions which are never used outside of their respective code unit, but which are lacking the `static` keyword. Add it to reduce their linkage scope and allow the compiler to optimize better.
Patrick Steinhardt 7c499b54 2020-06-08T12:39:09 tree-wide: remove unused functions We have some functions which aren't used anywhere. Let's remove them to get rid of unneeded baggage.
Patrick Steinhardt 939cb73f 2020-06-08T15:28:20 examples: log: fix documentation generation Docurium seems to be confused by our use of `/** comment */;` use in the log example. Let's just switch it around to help Docurium get this right.
Patrick Steinhardt 46637b5e 2020-06-08T14:47:01 checkout: remove unused code for deferred removals With commit 05f690122 (checkout: remove blocking dir when FORCEd, 2015-03-31), the last case was removde that actually queued a deferred removal. This is now more than five years in the past and nobody complained, so we can rest quite assured that the deferred removal is not really needed at all. Let's remove all related code to simplify the already complicated checkout logic.
Patrick Steinhardt 9e4e25b1 2020-06-08T12:57:48 tests: refs: modernize coding style of testcase The coding style of the testcase refs::create::propagate_eexists is not really up-to-date. Convert it to use a more modern coding style.
Patrick Steinhardt 45901d3e 2020-06-08T12:57:16 revparse: remove superfluous tab character
Patrick Steinhardt c146374c 2020-06-08T12:54:26 revparse: detect out-of-memory cases when parsing curly brace contents When extracting curly braces (e.g. the "upstream" part in "HEAD@{upstream}"), we put the curly braces' contents into a `git_buf` structure, but don't check the return value of `git_buf_putc`. So when we run out-of-memory, we'll use a partially filled buffer without noticing. Let's fix this issue by checking `git_buf_putc`'s return value.
