Edward Thomson f88e12db 2020-05-23T09:35:53 checkout::index: free the index
Patrick Steinhardt 3f201f75 2020-05-16T13:48:04 checkout: fix file being treated as unmodified due to racy index When trying to determine whether a file changed, we try to avoid heavy operations by fist taking a look at the index, seeing whether the index entry is modified already. This doesn't seem to cut it, though, as we currently have the racy checkout::index::can_disable_pathspec_match test case: sometimes the files get restored to their original contents, sometimes they aren't. The issue is caused by a racy index [1]: in case we modify a file, add it to the index and then modify it again in-place without changing its file, then we may end up with a modified file that has the same stat(3P) info as we've currently got it in its corresponding index entry. The mitigation for this is to treat files with the same mtime as the index are treated as racily modified. We already have this logic in place for the index, but not when doing a checkout. Fix the issue by only consulting the index entry in case it has an older mtime as the index. Previously, the following script reliably had at least 20 failures, while now there is no failure to be observed anymore: ```bash j=0 for i in $(seq 100) do if ! ./libgit2_clar -scheckout::index::can_disable_pathspec_match >/dev/null then j=$(($j + 1)) fi done echo "Failures: $j" ``` [1]: https://git-scm.com/docs/racy-git
Patrick Steinhardt 915f8860 2020-05-16T14:00:11 tests: checkout: fix stylistic issues and static variable The test case checkout::index::can_disable_pathspec_match has some shortcomings when it comes to coding style, which didn't fit our own coding style. Furthermore, it had an unnecessary static local variable. The test has been refactored to address these issues.
Patrick Steinhardt b85eefb4 2020-05-15T19:52:40 cmake: Sort source files for reproducible builds We currently use `FILE(GLOB ...)` in most places to find source and header files. This is problematic in that the order of files returned depends on the operating system's directory iteration order and may thus not be deterministic. As a result, we link object files in unspecified order, which may cause the linker to emit different code across runs. Fix this issue by sorting all code used as input to the libgit2 library to improve the reliability of reproducible builds.

Patrick Steinhardt a2eca682 2020-05-12T21:35:07 futils: fix order of declared parameters for `git_futils_fake_symlink` While the function `git_futils_fake_symlink` is declared with arguments `new, old`, the implementation uses the reverse order `old, new`. Let's fix the ordering issues to be `new, old` for both, which matches what symlink(3P) has. While at it, we also rename these parameters: `old` and `new` doesn't really make a lot of sense in the context of symlinks, which is why this commit renames them to be called `target` and `path`.

Patrick Steinhardt 0cf9b666 2020-05-12T11:41:44 tests: merge: fix printf formatter on 32 bit arches We currently use `PRIuMAX` to print an integer of type `size_t` in merge::trees::rename::cache_recomputation. While this works just fine on 64 bit arches, it doesn't on 32 bit ones. As a result, our nightly builds on x86 and arm32 fail. Fix the issue by using `PRIuZ` instead.

Edward Thomson cbae1c21 2020-04-01T22:12:07 assert: allow non-int returning functions to assert Include GIT_ASSERT_WITH_RETVAL and GIT_ASSERT_ARG_WITH_RETVAL so that functions that do not return int (or more precisely, where `-1` would not be an error code) can assert. This allows functions that return, eg, NULL on an error code to do that by passing the return value (in this example, `NULL`) as a second parameter to the GIT_ASSERT_WITH_RETVAL functions.
Edward Thomson a95096ba 2020-01-12T10:31:07 assert: optionally fall-back to assert(3) Fall back to the system assert(3) in debug builds, which may aide in debugging. "Safe" assertions can be enabled in debug builds by setting GIT_ASSERT_HARD=0. Similarly, hard assertions can be enabled in release builds by setting GIT_ASSERT_HARD to nonzero.
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 63de2128 2020-02-02T20:20:19 checkout: filter pathspecs for _all_ checkout types We were previously applying the pathspec filter for the baseline iterator during checkout, as well as the target tree. This was an oversight; in fact, we should apply the pathspec filter to _all_ checkout targets, not just trees. Add a helper function to set the iterator pathspecs from the given checkout pathspecs, and call it everywhere.

Patrick Steinhardt ffb6a576 2020-04-04T14:36:27 docs: add documentation for our coding style For years, we've repeatedly had confusion about what our actual coding style is not only for newcomers, but also across the core contributors. This can mostly be attributed to the fact that we do not have any coding conventions written down. This is now a thing of the past with the introduction of a new document that gives an initial overview of our style and most important best practices for both our C codebase as well as for CMake. While the proposed coding style for our C codebase should be rather uncontroversial, the coding style for CMake might be. This can be attributed to multiple facts. First, the CMake code base doesn't really have any uniform coding style and is quite outdated in a lot of places. Second, the proposed coding style actually breaks with our existing one: we currently use all-uppercase function names and variables, but the documented coding style says we use all-lowercase function names but all-uppercase variables. It's common practice in CMake to write variables in all upper-case, and in fact all variables made available by CMake are exactly that. As variables are case-sensitive in CMake, we cannot and shouldn't break with this. In contrast, function calls are case insensitive, and modern CMake always uses all-lowercase ones. I argue we should do the same to get in line with other codebases and to reduce the likelihood of repetitive strain injuries. So especially for CMake, the proposed coding style says something we don't have yet. I'm fine with that, as the document explicitly says that it's what we want to have and not what we have right now.

lhchavez f3273725 2020-02-25T20:58:09 pack: Improve error handling for get_delta_base() This change moves the responsibility of setting the error upon failures of get_delta_base() to get_delta_base() instead of its callers. That way, the caller chan always check if the return value is negative and mark the whole operation as an error instead of using garbage values, which can lead to crashes if the .pack files are malformed.

Patrick Steinhardt 4dfcc50f 2020-04-01T15:16:18 merge: cache negative cache results for similarity metrics When computing renames, we cache the hash signatures for each of the potentially conflicting entries so that we do not need to repeatedly read the file and can at least halfway efficiently determine whether two files are similar enough to be deemed a rename. In order to make the hash signatures meaningful, we require at least four lines of data to be present, resulting in at least four different hashes that can be compared. Files that are deemed too small are not cached at all and will thus be repeatedly re-hashed, which is usually not a huge issue. The issue with above heuristic is in case a file does _not_ have at least four lines, where a line is anything separated by a consecutive run of "\n" or "\0" characters. For example "a\nb" is two lines, but "a\0\0b" is also just two lines. Taken to the extreme, a file that has megabytes of consecutive space- or NUL-only may also be deemed as too small and thus not get cached. As a result, we will repeatedly load its blob, calculate its hash signature just to finally throw it away as we notice it's not of any value. When you've got a comparitively big file that you compare against a big set of potentially renamed files, then the cost simply expodes. The issue can be trivially fixed by introducing negative cache entries. Whenever we determine that a given blob does not have a meaningful representation via a hash signature, we store this negative cache marker and will from then on not hash it again, but also ignore it as a potential rename target. This should help the "normal" case already where you have a lot of small files as rename candidates, but in the above scenario it's savings are extraordinarily high. To verify we do not hit the issue anymore with described solution, this commit adds a test that uses the exact same setup described above with one 50 megabyte blob of '\0' characters and 1000 other files that get renamed. Without the negative cache: $ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null real 11m48.377s user 11m11.576s sys 0m35.187s And with the negative cache: $ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null real 0m1.972s user 0m1.851s sys 0m0.118s So this represents a ~350-fold performance improvement, but it obviously depends on how many files you have and how big the blob is. The test number were chosen in a way that one will immediately notice as soon as the bug resurfaces.

Patrick Steinhardt 5f47cb48 2020-03-26T14:16:41 patch: correctly handle mode changes for renames When generating a patch for a renamed file whose mode bits have changed in addition to the rename, then we currently fail to parse the generated patch. Furthermore, when generating a diff we output mode bits after the similarity metric, which is different to how upstream git handles it. Fix both issues by adding another state transition that allows similarity indices after mode changes and by printing mode changes before the similarity index.

Edward Thomson 153199ae 2020-03-17T09:42:41 ci: don't use --insecure mbedTLS has fixed their certificate. 🎉
Patrick Steinhardt 87fc539f 2020-03-13T22:08:19 cmake: use install directories provided via GNUInstallDirs We currently hand-code logic to configure where to install our artifacts via the `LIB_INSTALL_DIR`, `INCLUDE_INSTALL_DIR` and `BIN_INSTALL_DIR` variables. This is reinventing the wheel, as CMake already provide a way to do that via `CMAKE_INSTALL_<DIR>` paths, e.g. `CMAKE_INSTALL_LIB`. This requires users of libgit2 to know about the discrepancy and will require special hacks for any build systems that handle these variables in an automated way. One such example is Gentoo Linux, which sets up these paths in both the cmake and cmake-utils eclass. So let's stop doing that: the GNUInstallDirs module handles it in a better way for us, especially so as the actual values are dependent on CMAKE_INSTALL_PREFIX. This commit removes our own set of variables and instead refers users to use the standard ones. As a second benefit, this commit also fixes our pkgconfig generation to use the GNUInstallDirs module. We had a bug there where we ignored the CMAKE_INSTALL_PREFIX when configuring the libdir and includedir keys, so if libdir was set to "lib64", then libdir would be an invalid path. With GNUInstallDirs, we can now use `CMAKE_INSTALL_FULL_LIBDIR`, which handles the prefix for us.

Patrick Steinhardt 95f329b4 2020-03-10T21:07:34 azure: upgrade to newer hosted VM images Azure is phasing out old images on March 23rd 2020, but we're currently still using them. So let's upgrade images as following: - Ubuntu 16.04 -> ubuntu-18.04 - macOS 10.13 -> macOS-10.15 - Hosted Windows machines -> vs2017-win2016 Each of them is currently the latest version. As the new Microsoft Windows machine has upgraded to MSVS2017, we need to also adjust our CMake generators to "Visual Studio 15 2017". As this CMake generator doesn't accept the target platform name anymore, we instead need to set it up via either "-A Win32" or "-A x64".

Patrick Steinhardt 5ac33ced 2020-03-10T21:39:39 azure: docurium: fix build failure due to bumped CMake requirements Our Docurium builds currently depend on Debian Jessie, which has CMake v3.0 available. As rugged has bumped its CMake requirements to need at least v3.5 now, the documentation build is thus failing. Fix this by converting our Docurium Docker image to be based on Ubuntu Bionic. We already do base all of our images on Ubuntu, so I don't see any sense in using Debian here. If this was only to speed up builds, we should just go all the way and use some minimal container like Alpine anyway. Also remove cache busters. As we're rebuilding the image every time, it's we really don't need them at all.

Patrick Steinhardt 163db8f2 2020-02-28T18:53:22 win32: test relative symlinks Ensure that we don't canonicalize symlink targets.
Edward Thomson 43d7a42b 2020-03-08T18:14:09 win32: don't canonicalize symlink targets Don't canonicalize symlink targets; our win32 path canonicalization routines expect an absolute path. In particular, using the path canonicalization routines for symlink targets (introduced in commit 7d55bee6d, "win32: fix relative symlinks pointing into dirs", 2020-01-10). Now, use the utf8 -> utf16 relative path handling functions, so that paths like "../foo" will be translated to "..\foo".
Edward Thomson f2b114ba 2020-03-08T18:11:45 win32: introduce relative path handling function Add a function that takes a (possibly) relative UTF-8 path and emits a UTF-16 path with forward slashes translated to backslashes. If the given path is, in fact, absolute, it will be translated to absolute path handling rules.
Edward Thomson fb7da154 2020-03-08T16:34:23 win32: clarify usage of path canonicalization funcs The path canonicalization functions on win32 are intended to canonicalize absolute paths; those with prefixes. In other words, things start with drive letters (`C:\`), share names (`\\server\share`), or other prefixes (`\\?\`). This function removes leading `..` that occur after the prefix but before the directory/file portion (eg, turning `C:\..\..\..\foo` into `C:\foo`). This translation is not appropriate for local paths.

Edward Thomson 502e5d51 2020-03-01T12:44:39 httpclient: use a 16kb read buffer for macOS Use a 16kb read buffer for compatibility with macOS SecureTransport. SecureTransport `SSLRead` has the following behavior: 1. It will return _at most_ one TLS packet's worth of data, and 2. It will try to give you as much data as you asked for This means that if you call `SSLRead` with a buffer size that is smaller than what _it_ reads (in other words, the maximum size of a TLS packet), then it will buffer that data for subsequent calls. However, it will also attempt to give you as much data as you requested in your SSLRead call. This means that it will guarantee a network read in the event that it has buffered data. Consider our 8kb buffer and a server sending us 12kb of data on an HTTP Keep-Alive session. Our first `SSLRead` will read the TLS packet off the network. It will return us the 8kb that we requested and buffer the remaining 4kb. Our second `SSLRead` call will see the 4kb that's buffered and decide that it could give us an additional 4kb. So it will do a network read. But there's nothing left to read; that was the end of the data. The HTTP server is waiting for us to provide a new request. The server will eventually time out, our `read` system call will return, `SSLRead` can return back to us and we can make progress. While technically correct, this is wildly ineffecient. (Thanks, Tim Apple!) Moving us to use an internal buffer that is the maximum size of a TLS packet (16kb) ensures that `SSLRead` will never buffer and it will always return everything that it read (albeit decrypted).
