| | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible that somebody on the project committee is the subject of a complaint. In that case, it may be useful to be able to contact the other members individually, so let's make it clear that's an option. This also serves to enumerate the set of people on the committee. That lets you easily _know_ if you're in the situation mentioned above. And it's just convenient to list who's involved in the process, since the project committee list is not anywhere else in the repository.

| * add a Code of Conduct documentJeff King2019-10-101-0/+85

Though it has been discussed off and on over the years, for the most part the behavior on the mailing list has been good enough that nobody felt the need to push one forward. However, even if there aren't specific problems now, it's a good idea to have a document: - it puts everybody on the same page with respect to expectations. This might avoid poor behavior, but also makes it easier to handle it if it does happen. - it publicly advertises that good conduct is important to us and will be enforced, which may make some people more comfortable with joining our community - it may be a good time to cement our expectations when things are quiet, since it gives everybody some distance rather than focusing on a current contentious issue This patch adapts the Contributor Covenant Code of Conduct. As opposed to writing our own from scratch, this uses common and well-accepted language, and strikes a good balance between illustrating expectations and avoiding a laundry list of behaviors. It's also the same document used by the Git for Windows project. The text is taken mostly verbatim from: https://www.contributor-covenant.org/version/1/4/code-of-conduct.html I also stole a very nice introductory paragraph from the Git for Windows version of the file. There are a few subtle points, though: - the document refers to "the project maintainers". For the code, we generally only consider there to be one maintainer: Junio C Hamano. But for dealing with community issues, it makes sense to involve more people to spread the responsibility. I've listed the project committee address of git@sfconservancy.org as the contact point. - the document mentions banning from the community, both in the intro paragraph and in "Our Responsibilities". The exact mechanism here is left vague. I can imagine it might start with social enforcement (not accepting patches, ignoring emails) and could escalate to technical measures if necessary (asking vger admins to block an address). It probably make sense _not_ to get too specific at this point, and deal with specifics as they come up.

For each ref, it first checks if the ref exists locally, and if it does, passes it with a "^" prefix to pack-objects. However, in a partial clone, the check may trigger a lazy fetch. The additional commit ancestry information obtained during such fetches may show that certain objects that would have been sent are already known to the server, resulting in a smaller pack being sent. But this is at the cost of fetching from many possibly unrelated refs, and the lazy fetches do not help at all in the typical case where the client is up-to-date with the upstream of the branch being pushed. Ensure that these lazy fetches do not occur. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Although functionally correct, if format-patch ever produced incorrect output, the debugging output would be a bunch of hashes which would be difficult to debug.

However it was missed that its (then) only caller, 'find_header' did some error handling, and completing 'struct patch' appropriately. range-diff then started using this function, and tried to handle this appropriately itself, but fell short in some cases. This in turn would lead to range-diff segfaulting when there are mode-only changes in a range. Move the error handling and completing of the struct into the 'parse_git_diff_header' function, so other callers can take advantage of it. This fixes the segfault in 'git range-diff'.

This was not noticed because hashmap_entry_init takes a "void *" arg instead of "struct hashmap_entry *", and the hashmap struct is larger and can be cast into a hashmap_entry struct without data corruption. This has the beneficial side effect of reducing the size of a delta_base_cache_entry from 104 bytes to 72 bytes on 64-bit systems.

Writing this message into the sentinel file is useful for tracking how often the file count check triggers in practice. Bump up the event format version since we've added a new event type.

With heavy usage, this directory can fill up with files, causing difficulty for trace-processing systems. This patch adds a config option (trace2.maxFiles) to set a maximum number of files that trace2 will write to a target directory. The following behavior is enabled when the maxFiles is set to a positive integer: When trace2 would write a file to a target directory, first check whether or not the traces should be discarded. Traces should be discarded if: * there is a sentinel file declaring that there are too many files * OR, the number of files exceeds trace2.maxFiles. In the latter case, we create a sentinel file named git-trace2-discard to speed up future checks. The assumption is that a separate trace-processing system is dealing with the generated traces; once it processes and removes the sentinel file, it should be safe to generate new trace files again. The default value for trace2.maxFiles is zero, which disables the file count check. The config can also be overridden with a new environment variable: GIT_TRACE2_MAX_FILES.

This can be seen git.git with 74c7cfa875 (Merge of http://members.cox.net/junkio/git-jc.git, 2005-05-05), whose second child is 211232bae6 (Octopus merge of the following five patches., 2005-05-05). If one runs git log --graph 74c7cfa875 one can see that the octopus merge is colored incorrectly. In particular, the horizontal dashes are off by one color. Each horizontal dash should be the color of the line to their bottom-right. Instead, they are currently the color of the line to their bottom. Demonstrate this breakage with a few sets of test cases. These test cases should show not only simple cases of the bug occuring but trickier situations that may not be handled properly in any attempt to fix the bug. While we're at it, include a passing test case as a canary in case an attempt to fix the bug breaks existing operation.
