This however did not work well if the repository is set to + be shared with core.sharedRepository and the umask of the previous + user is tighter. They have been made to work better by calling + unlink(2) and retrying after fopen(3) fails with EPERM. + + * Asking gitweb for a nonexistent commit left a warning in the server + log. + + * "git rebase", unlike all other callers of "gc --auto", did not + ignore the exit code from "gc --auto". + + * Many codepaths that run "gc --auto" before exiting kept packfiles + mapped and left the file descriptors to them open, which was not + friendly to systems that cannot remove files that are open. They + now close the packs before doing so. + + * A recent optimization to filter-branch in v2.7.0 introduced a + regression when --prune-empty filter is used, which has been + corrected. + + * The description for SANITY prerequisite the test suite uses has + been clarified both in the comment and in the implementation. + + * "git tag" started listing a tag "foo" as "tags/foo" when a branch + named "foo" exists in the same repository; remove this unnecessary + disambiguation, which is a regression introduced in v2.7.0. + + * The way "git svn" uses auth parameter was broken by Subversion + 1.9.0 and later. + + * The "split" subcommand of "git subtree" (in contrib/) incorrectly + skipped merges when it shouldn't, which was corrected. + + * A few options of "git diff" did not work well when the command was + run from a subdirectory. + + * dirname() emulation has been added, as Msys2 lacks it. + + * The underlying machinery used by "ls-files -o" and other commands + have been taught not to create empty submodule ref cache for a + directory that is not a submodule. This removes a ton of wasted + CPU cycles. + + * Drop a few old "todo" items by deciding that the change one of them + suggests is not such a good idea, and doing the change the other + one suggested to do. + + * Documentation for "git fetch --depth" has been updated for clarity. + + * The command line completion learned a handful of additional options + and command specific syntax. + +Also includes a handful of documentation and test updates. diff --git a/Documentation/fetch-options.txt b/Documentation/fetch-options.txt index 45583d8454..78cd2653cd 100644 --- a/Documentation/fetch-options.txt +++ b/Documentation/fetch-options.txt @@ -8,10 +8,11 @@ option old data in `.git/FETCH_HEAD` will be overwritten. --depth=<depth>:: - Deepen or shorten the history of a 'shallow' repository created by - `git clone` with `--depth=<depth>` option (see linkgit:git-clone[1]) - to the specified number of commits from the tip of each remote - branch history.
