UI, Workflows & Features
- *
+ * Various updates to "git p4".
+
+ * "git p4" didn't interact with the internal of .git directory
+ correctly in the modern "git-worktree"-enabled world.
+
+ * "git branch --list" and friends learned "--ignore-case" option to
+ optionally sort branches and tags case insensitively.
+
+ * In addition to %(subject), %(body), "log --pretty=format:..."
+ learned a new placeholder %(trailers).
+
+ * "git rebase" learned "--quit" option, which allows a user to
+ remove the metadata left by an earlier "git rebase" that was
+ manually aborted without using "git rebase --abort".
+
+ * "git clone --reference $there --recurse-submodules $super" has been
+ taught to guess repositories usable as references for submodules of
+ $super that are embedded in $there while making a clone of the
+ superproject borrow objects from $there; extend the mechanism to
+ also allow submodules of these submodules to borrow repositories
+ embedded in these clones of the submodules embedded in the clone of
+ the superproject.
+
+ * Porcelain scripts written in Perl are getting internationalized.
+
+ * "git merge --continue" has been added as a synonym to "git commit"
+ to conclude a merge that has stopped due to conflicts.
+
+ * Finer-grained control of what protocols are allowed for transports
+ during clone/fetch/push have been enabled via a new configuration
+ mechanism.
+
+ * "git shortlog" learned "--committer" option to group commits by
+ committer, instead of author.
+
+ * GitLFS integration with "git p4" has been updated.
+
+ * The isatty() emulation for Windows has been updated to eradicate
+ the previous hack that depended on internals of (older) MSVC
+ runtime.
Performance, Internal Implementation, Development Support etc.
- *
+ * Commands that operate on a log message and add lines to the trailer
+ blocks, such as "format-patch -s", "cherry-pick (-x|-s)", and
+ "commit -s", have been taught to use the logic of and share the
+ code with "git interpret-trailer".
+ * The default Travis-CI configuration specifies newer P4 and GitLFS.
+ (merge 5f703e8f02 ls/travis-update-p4-and-lfs later to maint).
-Also contains various documentation updates and code clean-ups.
+ * The "fast hash" that had disastrous performance issues in some
+ corner cases has been retired from the internal diff.
+
+ * The character width table has been updated to match Unicode 9.0
+ (merge 9e6e9aefdf bb/unicode-9.0 later to maint).
- *
+ * Update the procedure to generate "tags" for developer support.
+ (merge 046e4c1c09 jk/make-tags-find-sources-tweak later to maint).
+
+Also contains various documentation updates and code clean-ups.
+
Fixes since v2.10
-----------------
some configuration variable it uses were not documented.
(merge ea9a93dcc2 ew/svn-fixes later to maint).
+ * "git rev-parse --symbolic" failed with a more recent notation like
+ "HEAD^-1" and "HEAD^!".
+ (merge a2e7b04c44 jk/rev-parse-symbolic-parents-fix later to maint).
+
+ * An empty directory in a working tree that can simply be nuked used
+ to interfere while merging or cherry-picking a change to create a
+ submodule directory there, which has been fixed..
+ (merge 5423d2e700 dt/empty-submodule-in-merge later to maint).
+
+ * The code in "git push" to compute if any commit being pushed in the
+ superproject binds a commit in a submodule that hasn't been pushed
+ out was overly inefficient, making it unusable even for a small
+ project that does not have any submodule but have a reasonable
+ number of refs.
+ (merge 250ab24ab3 hv/submodule-not-yet-pushed-fix later to maint).
+
+ * "git push --dry-run --recurse-submodule=on-demand" wasn't
+ "--dry-run" in the submodules.
+ (merge 0301c821c5 bw/push-dry-run later to maint).
+
+ * The output from "git worktree list" was made in readdir() order,
+ and was unstable.
+ (merge 4df1d4d466 nd/worktree-list-fixup later to maint).
+
+ * mergetool.<tool>.trustExitCode configuration variable did not apply
+ to built-in tools, but now it does.
+ (merge 2967284456 da/mergetool-trust-exit-code later to maint).
+
+ * "git p4" LFS support was broken when LFS stores an empty blob.
+ (merge d5eb3cf5e7 ls/p4-empty-file-on-lfs later to maint).
+
+ * A corner case in merge-recursive regression that crept in
+ during 2.10 development cycle has been fixed.
+ (merge 1c25d2d8ed jc/renormalize-merge-kill-safer-crlf later to maint).
+
+ * Transport with dumb http can be fooled into following foreign URLs
+ that the end user does not intend to, especially with the server
+ side redirects and http-alternates mechanism, which can lead to
+ security issues. Tighten the redirection and make it more obvious
+ to the end user when it happens.
+ (merge cb4d2d35c4 jk/http-walker-limit-redirect-2.9 later to maint).
+
+ * Update the error messages from the dumb-http client when it fails
+ to obtain loose objects; we used to give sensible error message
+ only upon 404 but we now forbid unexpected redirects that needs to
+ be reported with something sensible.
+ (merge 3680f16f9d jk/http-walker-limit-redirect later to maint).
+
+ * When diff.renames configuration is on (and with Git 2.9 and later,
+ it is enabled by default, which made it worse), "git stash"
+ misbehaved if a file is removed and another file with a very
+ similar content is added.
+ (merge 9d4e28ead5 jk/stash-disable-renames-internally later to maint).
+
+ * "git diff --no-index" did not take "--no-abbrev" option.
+ (merge 43d1948b7b jb/diff-no-index-no-abbrev later to maint).
+
+ * "git difftool --dir-diff" had a minor regression when started from
+ a subdirectory, which has been fixed.
+ (merge 853e10c197 da/difftool-dir-diff-fix later to maint).
+
+ * "git commit --allow-empty --only" (no pathspec) with dirty index
+ ought to be an acceptable way to create a new commit that does not
+ change any paths, but it was forbidden, perhaps because nobody
+ needed it so far.
+ (merge beb635ca9c ak/commit-only-allow-empty later to maint).
+
+ * Git 2.11 had a minor regression in "merge --ff-only" that competed
+ with another process that simultanously attempted to update the
+ index. We used to explain what went wrong with an error message,
+ but the new code silently failed. The error message has been
+ resurrected.
+
+ * A pathname that begins with "//" or "\\" on Windows is special but
+ path normalization logic was unaware of it.
+ (merge 7814fbe3f1 js/normalize-path-copy-ceil later to maint).
+
+ * "git pull --rebase", when there is no new commits on our side since
+ we forked from the upstream, should be able to fast-forward without
+ invoking "git rebase", but it didn't.
+ (merge 33b842a1e9 jc/pull-rebase-ff later to maint).
+
+ * The way to specify hotkeys to "xxdiff" that is used by "git
+ mergetool" has been modernized to match recent versions of xxdiff.
+ (merge 6cf5f6cef7 da/mergetool-xxdiff-hotkey later to maint).
+
+ * Unlike "git am --abort", "git cherry-pick --abort" moved HEAD back
+ to where cherry-pick started while picking multiple changes, when
+ the cherry-pick stopped to ask for help from the user, and the user
+ did "git reset --hard" to a different commit in order to re-attempt
+ the operation.
+ (merge ce73bb22d8 sb/sequencer-abort-safety later to maint).
+
+ * Code cleanup in shallow boundary computation.
+ (merge 649b0c316a nd/shallow-fixup later to maint).
+
+ * A recent update to receive-pack to make it easier to drop garbage
+ objects made it clear that GIT_ALTERNATE_OBJECT_DIRECTORIES cannot
+ have a pathname with a colon in it (no surprise!), and this in turn
+ made it impossible to push into a repository at such a path. This
+ has been fixed by introducing a quoting mechanism used when
+ appending such a path to the colon-separated list.
+ (merge 5e74824fac jk/quote-env-path-list-component later to maint).
+
+ * The function usage_msg_opt() has been updated to say "fatal:"
+ before the custom message programs give, when they want to die
+ with a message about wrong command line options followed by the
+ standard usage string.
+ (merge 87433261a4 jk/parseopt-usage-msg-opt later to maint).
+
+ * "git index-pack --stdin" needs an access to an existing repository,
+ but "git index-pack file.pack" to generate an .idx file that
+ corresponds to a packfile does not.
+ (merge 29401e1575 jk/index-pack-wo-repo-from-stdin later to maint).
+
+ * Fix for NDEBUG builds.
+ (merge 08414938a2 jt/mailinfo-fold-in-body-headers later to maint).
+
+ * A lazy "git push" without refspec did not internally use a fully
+ specified refspec to perform 'current', 'simple', or 'upstream'
+ push, causing unnecessary "ambiguous ref" errors.
+ (merge b284495e93 jc/push-default-explicit later to maint).
+
+ * "git p4" misbehaved when swapping a directory and a symbolic link.
+ (merge df8a9e86db ld/p4-compare-dir-vs-symlink later to maint).
+
+ * Even though an fix was attempted in Git 2.9.3 days, but running
+ "git difftool --dir-diff" from a subdirectory never worked. This
+ has been fixed.
+ (merge ce6926974e jk/difftool-in-subdir later to maint).
+
+ * "git p4" that tracks multile p4 paths imported a single changelist
+ that touches files in these multiple paths as one commit, followed
+ by many empty commits. This has been fixed.
+ (merge 9943e5b979 gv/p4-multi-path-commit-fix later to maint).
+
+ * A potential but unlikely buffer overflow in Windows port has been
+ fixed.
+ (merge c46458e82f mk/mingw-winansi-ttyname-termination-fix later to maint).
+
* Other minor doc, test and build updates and code cleanups.
+ (merge fa6ca11105 nd/qsort-in-merge-recursive later to maint).
+ (merge fa3142c919 ak/lazy-prereq-mktemp later to maint).
