UI, Workflows & Features
+ * A triangular "pull from one place, push to another place" workflow
+ is supported better by new remote.pushdefault (overrides the
+ "origin" thing) and branch.*.pushremote (overrides the
+ branch.*.remote) configuration variables.
+
+ * "git status" learned to report that you are in the middle of a
+ revert session, just like it does for a cherry-pick and a bisect
+ session.
+
+ * The handing by "git branch --set-upstream-to" against various forms
+ of errorneous inputs was suboptimal and has been improved.
+
* When the interactive access to git-shell is not enabled, it issues
a message meant to help the system admininstrator to enable it.
An explicit way to help the end users who connect to the service by
* The new "--follow-tags" option tells "git push" to push relevant
annotated tags when pushing branches out.
+ * "git merge" and "git pull" can optionally be told to inspect and
+ reject when merging a commit that does not carry a trusted GPG
+ signature.
+
* "git mergetool" now feeds files to the "p4merge" backend in the
order that matches the p4 convention, where "theirs" is usually
shown on the left side, which is the opposite from other backend
expects.
+ * "show/log" now honors gpg.program configuration just like other
+ parts of the code that use GnuPG.
+
+ * "git log" that shows the difference between the parent and the
+ child has been optimized somewhat.
+
+ * "git difftool" allows the user to write into the temporary files
+ being shown; if the user makes changes to the working tree at the
+ same time, one of the changes has to be lost in such a case, but it
+ tells the user what happened and refrains from overwriting the copy
+ in the working tree.
+
+ * There was no good way to ask "I have a random string that came from
+ outside world. I want to turn it into a 40-hex object name while
+ making sure such an object exists". A new peeling suffix ^{object}
+ can be used for that purpose, together with "rev-parse --verify".
+
Performance, Internal Implementation, etc.
* Updates for building under msvc.
+ * The code to enforce permission bits on files in $GIT_DIR/ for
+ shared repositories have been simplified.
+
* A few codepaths knew how much data they need to put in the
hashtables they use upfront, but still started from a small table
repeatedly growing and rehashing.
* The pkt-line API, implementation and its callers have been cleaned
up to make them more robust.
+ * Cygwin port has a faster-but-lying lstat(2) emulation whose
+ incorrectness does not matter in practice except for a few
+ codepaths, and setting permission bits to directories is a codepath
+ that needs to use a more correct one.
+
+ * "git checkout" had repeated pathspec matches on the same paths,
+ which have been consolidated. Also a bug in "git checkout dir/"
+ that is started from an unmerged index has been fixed.
+
Also contains minor documentation updates and code clean-ups.
track are contained in this release (see release notes to them for
details).
+ * When used with "-d temporary-directory" option, "git filter-branch"
+ failed to come back to the original working tree to perform the
+ final clean-up procedure.
+ (merge 9727601 jk/filter-branch-come-back-to-original later to maint).
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+ "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+ not pay much attention to the annotated tag payload. Make the code
+ notice the type of the tag object, in addition to the dwim_ref()
+ based classification the current code uses (i.e. the name appears
+ in refs/tags/) to decide when to special case merging of tags.
+ (merge a38d3d7 jc/merge-tag-object later to maint).
+
+ * Fix 1.8.1.x regression that stopped matching "dir" (without
+ trailing slash) to a directory "dir".
+ (merge efa5f82 jc/directory-attrs-regression-fix later to maint-1.8.1).
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+ longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+ (merge 329b26e jc/apply-ws-fix-tab-in-indent later to maint-1.8.1).
+
+ * The prompt string generator (in contrib/completion/) did not notice
+ when we are in a middle of a "git revert" session.
+ (merge 3ee4452 rr/prompt-revert-head later to maint).
+
+ * "submodule summary --summary-limit" option did not support
+ "--option=value" form.
+ (merge 862ae6c rs/submodule-summary-limit later to maint).
+
* "index-pack --fix-thin" used uninitialize value to compute delta
depths of objects it appends to the resulting pack.
(merge 57165db jk/index-pack-correct-depth-fix later to maint).
* The code to keep track of what directory names are known to Git on
platforms with case insensitive filesystems can get confused upon a
hash collision between these pathnames and looped forever.
- (merge 2092678 kb/name-hash later to maint).
* Annotated tags outside refs/tags/ hierarchy were not advertised
correctly to the ls-remote and fetch with recent version of Git.
- (merge c29c46f jk/fully-peeled-packed-ref later to maint).
* Recent optimization broke shallow clones.
(merge f59de5d jk/peel-ref later to maint).
* "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
instead the parser kept reading beyond the end of the string.
- (merge f612a67 lf/setup-prefix-pathspec later to maint).
* "git tag -f <tag>" always said "Updated tag '<tag>'" even when
creating a new tag (i.e. not overwriting nor updating).
- (merge 3ae851e ph/tag-force-no-warn-on-creation later to maint).
* "git p4" did not behave well when the path to the root of the P4
client was not its real path.
* "git archive" reports a failure when asked to create an archive out
of an empty tree. It would be more intuitive to give an empty
archive back in such a case.
- (merge bd54cf1 jk/empty-archive later to maint).
* When "format-patch" quoted a non-ascii strings on the header files,
it incorrectly applied rfc2047 and chopped a single character in
the middle of it.
- (merge 6cd3c05 ks/rfc2047-one-char-at-a-time later to maint).
* An aliased command spawned from a bare repository that does not say
it is bare with "core.bare = yes" is treated as non-bare by mistake.
- (merge 2cd83d1 jk/alias-in-bare later to maint).
* In "git reflog expire", REACHABLE bit was not cleared from the
correct objects.
"--all" to allow refs that are not annotated tags to be used as a
base of description, did not restrict the output from the command
to those that match the given pattern.
- (merge 46e1d6e jc/describe later to maint).
* Clarify in the documentation "what" gets pushed to "where" when the
command line to "git push" does not say these explicitly.
* 'git commit -m "$msg"' used to add an extra newline even when
$msg already ended with one.
- (merge 46fbf75 bc/commit-complete-lines-given-via-m-option later to maint).
* The SSL peer verification done by "git imap-send" did not ask for
Server Name Indication (RFC 4366), failing to connect SSL/TLS
* Verification of signed tags were not done correctly when not in C
or en/US locale.
- (merge 0174eea mg/gpg-interface-using-status later to maint).
* Some platforms and users spell UTF-8 differently; retry with the
most official "UTF-8" when the system does not understand the
