+it before Git 2.0 comes. A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal. Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour is encouraged to use "git add --ignore-removal <path>" and
+get used to it.
Updates since v1.8.2
--------------------
+Foreign interface
+
+ * remote-hg and remote-bzr helpers (in contrib/) have been updated.
+
+
UI, Workflows & Features
+ * "git branch --vv" learned to paint the name of the branch it
+ integrates with in a different color (color.branch.upstream,
+ which defaults to blue).
+
+ * In a sparsely populated working tree, "git checkout <pathspec>" no
+ longer unmarks paths that match the given pathspec that were
+ originally ignored with "--sparse" (use --ignore-skip-worktree-bits
+ option to resurrect these paths out of the index if you really want
+ to).
+
+ * "git log --format" specifier learned %C(auto) token that tells Git
+ to use color when interpolating %d (decoration), %h (short commit
+ object name), etc. for terminal output.
+
+ * "git bisect" leaves the final outcome as a comment in its bisect
+ log file.
+
+ * "git clone --reference" can now refer to a gitfile "textual symlink"
+ that points at the real location of the repository.
+
+ * "git count-objects" learned "--human-readable" aka "-H" option to
+ show various large numbers in Ki/Mi/GiB scaled as necessary.
+
+ * "git cherry-pick $blob" and "git cherry-pick $tree" are nonsense,
+ and a more readable error message e.g. "can't cherry-pick a tree"
+ is given (we used to say "expected exactly one commit").
+
+ * The "--annotate" option to "git send-email" can be turned on (or
+ off) by default with sendemail.annotate configuration variable (you
+ can use --no-annotate from the command line to override it).
+
+ * The "--cover-letter" option to "git format-patch" can be turned on
+ (or off) by default with format.coverLetter configuration
+ variable. By setting it to 'auto', you can turn it on only for a
+ series with two or more patches.
+
+ * The bash completion support (in contrib/) learned that cherry-pick
+ takes a few more options than it already knew about.
+
+ * "git help" learned "-g" option to show the list of guides just like
+ list of commands are given with "-a".
+
+ * 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 handling by "git branch --set-upstream-to" against various forms
+ of erroneous 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.
+ a message meant to help the system administrator to enable it.
An explicit way to help the end users who connect to the service by
issuing custom messages to refuse such an access has been added.
- * "git status" suggests users to look into using--untracked=no option
+ * In addition to the case where the user edits the log message with
+ the "e)dit" option of "am -i", replace the "Applying: this patch"
+ message with the final log message contents after applymsg hook
+ munges it.
+
+ * "git status" suggests users to look into using --untracked=no option
when it takes too long.
+ * "git status" shows a bit more information to "git status" during a
+ rebase/bisect session.
+
* "git fetch" learned to fetch a commit at the tip of an unadvertised
ref by specifying a raw object name from the command line when the
server side supports this feature.
+ * Output from "git log --graph" works better with submodule log
+ output now.
+
* "git count-objects -v" learned to report leftover temporary
packfiles and other garbage in the object store.
* "git send-email" can be used with the credential helper system.
+ * There was no Porcelain way to say "I no longer am interested in
+ this submodule", once you express your interest in a submodule with
+ "submodule init". "submodule deinit" is the way to do so.
+
+ * "git pull --rebase" learned to pass "-v/-q" options to underlying
+ "git rebase".
+
+ * 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.
-Foreign Interface
+ * "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.
+ * A handful of issues in the code to traverse working tree to find
+ untracked and/or ignored files have been fixed, and the general
+ codepath involved in "status -u" and "clean" have been cleaned up
+ and optimized.
+
+ * The stack footprint of some codepaths that access an object from a
+ pack has been shrunk.
+
+ * The logic to coalesce the same lines removed from the parents in
+ the output from "diff -c/--cc" has been updated, but with an O(n^2)
+ complexity, so this might turn out to be undesirable.
+
+ * 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 API to walk reflog entries from the latest to older, which was
+ necessary for operations such as "git checkout -", was cumbersome
+ to use correctly and also inefficient.
+
+ * Codepaths that inspect log-message-to-be and decide when to add a
+ new Signed-off-by line in various commands have been consolidated.
+
+ * 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.
+ * A few bugfixes to "git rerere" working on corner case merge
+ conflicts have been applied.
+
+
+Also contains various documentation updates and code clean-ups.
Fixes since v1.8.2
track are contained in this release (see release notes to them for
details).
+ * When receive-pack detects error in the pack header it received in
+ order to decide which of unpack-objects or index-pack to run, it
+ returned without closing the error stream, which led to a hang
+ sideband thread.
+
+ * Zsh completion forgot that '%' character used to signal untracked
+ files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+ crashed some code that trusted that a name, an email and an
+ timestamp can always be found in it.
+
+ * When "upload-pack" fails while generating a pack in response to
+ "git fetch" (or "git clone"), the receiving side mistakenly said
+ there was a programming error to trigger the die handler
+ recursively.
+
+ * "rev-list --stdin" and friends kept bogus pointers into input
+ buffer around as human readble object names. This was not a huge
+ problem but was exposed by a new change that uses these names in
+ error output.
+ (merge 70d26c6 tr/copy-revisions-from-stdin later to maint).
+
+ * Smart-capable HTTP servers were not restricted via the
+ GIT_NAMESPACE mechanism when talking with commit-walker clients,
+ like they do when talking with smart HTTP clients.
+ (merge 6130f86 jk/http-dumb-namespaces later to maint).
+
+ * "git merge-tree" did not omit a merge result that is identical to
+ "our" side in certain cases.
+ (merge aacecc3 jk/merge-tree-added-identically later to maint).
+
+ * Perl scripts like "git-svn" closed (not redirecting to /dev/null)
+ the standard error stream, which is not a very smart thing to do.
+ Later open may return file descriptor #2 for unrelated purpose, and
+ error reporting code may write into them.
+
+ * "git show-branch" was not prepared to show a very long run of
+ ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.
+
+ * "git diff --diff-algorithm algo" is also understood as "git diff
+ --diff-algorithm=algo".
+
+ * The new core.commentchar configuration was not applied to a few
+ places.
+
+ * "git bundle" did not like a bundle created using a commit without
+ any message as its one of the prerequistes.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+ there was no way to disable this. Make it honor --no-textconv
+ option.
+
+ * 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.
+
+ * "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.
+
+ * 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.
+
+ * "submodule summary --summary-limit" option did not support
+ "--option=value" form.
+
+ * "index-pack --fix-thin" used an uninitialized value to compute
+ delta depths of objects it appends to the resulting pack.
+
+ * "index-pack --verify-stat" used a few counters outside protection
+ of mutex, possibly showing incorrect numbers.
+
+ * 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.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+ correctly to the ls-remote and fetch with recent version of Git.
+
+ * Recent optimization broke shallow clones.
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+ instead the parser kept reading beyond the end of the string.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+ creating a new tag (i.e. not overwriting nor updating).
+
+ * "git p4" did not behave well when the path to the root of the P4
+ client was not its real path.
+ (merge bbd8486 pw/p4-symlinked-root later to maint).
+
+ * "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.
+
+ * 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.
+
+ * 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.
+
+ * In "git reflog expire", REACHABLE bit was not cleared from the
+ correct objects.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+ files before and after a rename did not work correctly when the
+ common prefix and suffix between the two filenames overlapped.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+ "--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.
+
* Clarify in the documentation "what" gets pushed to "where" when the
command line to "git push" does not say these explicitly.
- (merge cfe1348 jc/maint-push-refspec-default-doc later to maint).
* The "--color=<when>" argument to the commands in the diff family
was described poorly.
- (merge 3d0e75f jc/color-diff-doc later to maint).
* The arguments given to pre-rebase hook were not documented.
- (merge 0414acc wk/doc-pre-rebase later to maint).
* The v4 index format was not documented.
- (merge 647d879 nd/doc-index-format later to maint).
* The "--match=<pattern>" argument "git describe" takes uses glob
pattern but it wasn't obvious from the documentation.
- (merge 5229149 gp/describe-match-uses-glob-pattern later to maint).
* Some sources failed to compile on systems that lack NI_MAXHOST in
their system header (e.g. z/OS).
- (merge 3b130ade dm/ni-maxhost-may-be-missing later to maint).
* Add an example use of "--env-filter" in "filter-branch"
documentation.
- (merge 21b6e4f tk/doc-filter-branch later to maint).
* "git bundle verify" did not say "records a complete history" for a
bundle that does not have any prerequisites.
- (merge a02ffe0 lf/bundle-verify-list-prereqs later to maint).
* In the v1.8.0 era, we changed symbols that do not have to be global
to file scope static, but a few functions in graph.c were used by
CGit from sideways bypassing the entry points of the API the
in-tree users use.
- (merge ac751a0 jk/graph-c-expose-symbols-for-cgit later to maint).
* "git update-index -h" did not do the usual "-h(elp)" thing.
* "git index-pack" had a buffer-overflow while preparing an
informational message when the translated version of it was too
long.
- (merge 5c3459f nd/index-pack-l10n-buf-overflow later to maint).
* '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
sites that serve multiple hostnames on a single IP.
- (merge 698a1ec ob/imap-send-ssl-verify later to maint).
* perl/Git.pm::cat_blob slurped everything in core only to write it
out to a file descriptor, which was not a very smart thing to do.
- (merge 712c6ad jc/perl-cat-blob later to maint).
* "git branch" did not bother to check nonsense command line
parameters and issue errors in many cases.
- (merge 8efb889 nd/branch-error-cases later to maint).
* 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
user-supplied encoding name that are the common alternative
spellings of UTF-8.
- (merge 5c680be jk/utf-8-can-be-spelled-differently later to maint).
* When export-subst is used, "zip" output recorded incorrect
size of the file.
- (merge d3c1472 rs/zip-compresssed-size-with-export-subst later to maint).
* "git am $maildir/" applied messages in an unexpected order; sort
filenames read from the maildir/ in a way that is more likely to
sort messages in the order the writing MUA meant to, by sorting
numeric segment in numeric order and non-numeric segment in
alphabetical order.
- (merge 18505c3 jk/mailsplit-maildir-muttsort later to maint).
* "git submodule update", when recursed into sub-submodules, did not
- acccumulate the prefix paths.
- (merge 75bf5e6 we/submodule-update-prefix-output later to maint).
+ accumulate the prefix paths.
