Git v1.8.5 Release Notes (draft)
========================
Backward compatibility notes (for Git 2.0)
------------------------------------------
When "git push [$there]" does not say what to push, we have used the
traditional "matching" semantics so far (all your branches were sent
to the remote as long as there already are branches of the same name
over there). In Git 2.0, the default will change to the "simple"
semantics that pushes:
- only the current branch to the branch with the same name, and only
when the current branch is set to integrate with that remote
branch, if you are pushing to the same remote as you fetch from; or
- only the current branch to the branch with the same name, if you
are pushing to a remote that is not where you usually fetch from.
Use the user preference configuration variable "push.default" to
change this. If you are an old-timer who is used to the "matching"
semantics, you can set the variable to "matching" to keep the
traditional behaviour. If you want to live in the future early, you
can set it to "simple" today without waiting for Git 2.0.
When "git add -u" (and "git add -A") is run inside a subdirectory and
does not specify which paths to add on the command line, it
will operate on the entire tree in Git 2.0 for consistency
with "git commit -a" and other commands. There will be no
mechanism to make plain "git add -u" behave like "git add -u .".
Current users of "git add -u" (without a pathspec) should start
training their fingers to explicitly say "git add -u ."
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 are encouraged to start using "git add --ignore-removal <path>"
now before 2.0 is released.
The default prefix for "git svn" will change in Git 2.0. For a long
time, "git svn" created its remote-tracking branches directly under
refs/remotes, but it will place them under refs/remotes/origin/ unless
it is told otherwise with its --prefix option.
Updates since v1.8.4
--------------------
Foreign interfaces, subsystems and ports.
* "git-svn" used with SVN 1.8.0 when talking over https:// connection
dumped core due to a bug in the serf library that SVN uses. Work
it around on our side, even though the SVN side is being fixed.
* On MacOS X, we detected if the filesystem needs the "pre-composed
unicode strings" workaround, but did not automatically enable it.
Now we do.
* remote-hg remote helper misbehaved when interacting with a local Hg
repository relative to the home directory, e.g. "clone hg::~/there".
* imap-send ported to OS X uses Apple's security framework instead of
OpenSSL one.
* Subversion 1.8.0 that was recently released breaks older subversion
clients coming over http/https in various ways.
* "git fast-import" treats an empty path given to "ls" as the root of
the tree.
UI, Workflows & Features
* xdg-open can be used as a browser backend for "git web-browse"
(hence to show "git help -w" output), when available.
* "git grep" and "git show" pays attention to "--textconv" option
when these commands are told to operate on blob objects (e.g. "git
grep -e pattern HEAD:Makefile").
* "git replace" helper no longer allows an object to be replaced with
another object of a different type to avoid confusion (you can
still manually craft such replacement using "git update-ref", as an
escape hatch).
* "git status" no longer prints dirty status information for
submodules for which submodule.$name.ignore is set to "all".
* "git rebase -i" honours core.abbrev when preparing the insn sheet
for editing.
* "git status" during a cherry-pick shows what original commit is
being picked.
* Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".
* "git check-ignore" follows the same rule as "git add" and "git
status" in that the ignore/exclude mechanism does not take effect
on paths that are already tracked. With "--no-index" option, it
can be used to diagnose which paths that should have been ignored
have been mistakenly added to the index.
* Some irrelevant "advice" messages that are shared with "git status"
output have been removed from the commit log template.
* "update-refs" learnt a "--stdin" option to read multiple update
requests and perform them in an all-or-none fashion.
* Just like "make -C <directory>", "git -C <directory> ..." tells Git
to go there before doing anything else.
* Just like "git checkout -" knows to check out and "git merge -"
knows to merge the branch you were previously on, "git cherry-pick"
now understands "git cherry-pick -" to pick from the previous
branch.
* "git status" now omits the prefix to make its output a comment in a
commit log editor, which is not necessary for human consumption.
Scripts that parse the output of "git status" are advised to use
"git status --porcelain" instead, as its format is stable and easier
to parse.
* Make "foo^{tag}" to peel a tag to itself, i.e. no-op., and fail if
"foo" is not a tag. "git rev-parse --verify v1.0^{tag}" would be
a more convenient way to say "test $(git cat-file -t v1.0) = tag".
* "git branch -v -v" (and "git status") did not distinguish among a
branch that does not build on any other branch, a branch that is in
sync with the branch it builds on, and a branch that is configured
to build on some other branch that no longer exists.
* Earlier we started rejecting an attempt to add 0{40} object name to
the index and to tree objects, but it sometimes is necessary to
allow so to be able to use tools like filter-branch to correct such
broken tree objects. "filter-branch" can again be used to to do
so.
* "git config" did not provide a way to set or access numbers larger
than a native "int" on the platform; it now provides 64-bit signed
integers on all platforms.
* "git pull --rebase" always chose to do the bog-standard flattening
rebase. You can tell it to run "rebase --preserve-merges" by
setting "pull.rebase" configuration to "preserve".
* "git push --no-thin" actually disables the "thin pack transfer"
optimization.
* Magic pathspecs like ":(icase)makefile" that matches both Makefile
and makefile and ":(glob)foo/**/bar" that matches "bar" in "foo"
and any subdirectory of "foo" can be used in more places.
* The "http.*" variables can now be specified per URL that the
configuration applies. For example,
[http]
sslVerify = true
[http "https://weak.example.com/";]
sslVerify = false
would flip http.sslVerify off only when talking to that specified
site.
* "git mv A B" when moving a submodule A has been taught to
relocate its working tree and to adjust the paths in the
.gitmodules file.
* "git blame" can now take more than one -L option to discover the
origin of multiple blocks of the lines.
* The http transport clients can optionally ask to save cookies
with http.savecookies configuration variable.
* "git push" learned a more fine grained control over a blunt
"--force" when requesting a non-fast-forward update with the
"--force-with-lease=<refname>:<expected object name>" option.
* "git diff --diff-filter=<classes of changes>" can now take
lowercase letters (e.g. "--diff-filter=d") to mean "show
everything but these classes". "git diff-files -q" is now a
deprecated synonym for "git diff-files --diff-filter=d".
* "git fetch" (hence "git pull" as well) learned to check
"fetch.prune" and "remote.*.prune" configuration variables and
to behave as if the "--prune" command line option was given.
* "git check-ignore -z" applied the NUL termination to both its input
(with --stdin) and its output, but "git check-attr -z" ignored the
option on the output side. Make both honor -z on the input and
output side the same way.
* "git whatchanged" may still be used by old timers, but mention of
it in documents meant for new users will only waste readers' time
wonderig what the difference is between it and "git log". Make it
less prominent in the general part of the documentation and explain
that it is merely a "git log" with different default behaviour in
its own document.
Performance, Internal Implementation, etc.
* "git for-each-ref" when asking for merely the object name does not
have to parse the object pointed at by the refs; the codepath has
been optimized.
* The HTTP transport will try to use TCP keepalive when able.
* "git repack" is now written in C.
* Build procedure for MSVC has been updated.
* If a build-time fallback is set to "cat" instead of "less", we
should apply the same "no subprocess or pipe" optimization as we
apply to user-supplied GIT_PAGER=cat.
* Many commands use --dashed-option as a operation mode selector
(e.g. "git tag --delete") that the user can use at most one
(e.g. "git tag --delete --verify" is a nonsense) and you cannot
negate (e.g. "git tag --no-delete" is a nonsense). parse-options
API learned a new OPT_CMDMODE macro to make it easier to implement
such a set of options.
* OPT_BOOLEAN() in parse-options API was misdesigned to be "counting
up" but many subcommands expect it to behave as "on/off". Update
them to use OPT_BOOL() which is a proper boolean.
* "git gc" exits early without doing a double-work when it detects
that another instance of itself is already running.
* Under memory pressure and/or file descriptor pressure, we used to
close pack windows that are not used and also closed filehandle to
an open but unused packfiles. These are now controlled separately
to better cope with the load.
Also contains various documentation updates and code clean-ups.
Fixes since v1.8.4
------------------
Unless otherwise noted, all the fixes since v1.8.4 in the maintenance
track are contained in this release (see release notes to them for
details).
* An ancient How-To on serving Git repositories on an HTTP server
lacked a warning that it has been mostly superseded with more
modern way.
(merge 6d52bc3 sc/doc-howto-dumb-http later to maint).
* The interaction between use of Perl in our test suite and NO_PERL
has been clarified a bit.
(merge f8fc0ee jn/test-prereq-perl-doc later to maint).
* The synopsis section of "git unpack-objects" documentation has been
clarified a bit.
(merge 61e2e22 vd/doc-unpack-objects later to maint).
* We did not generate HTML version of documentation to "git subtree"
in contrib/.
(merge 95c62fb jk/subtree-install-fix later to maint).
* A fast-import stream expresses a pathname with funny characters by
quoting them in C style; remote-hg remote helper forgot to unquote
such a path.
(merge 1136265 ap/remote-hg-unquote-cquote later to maint).
* "git reset -p HEAD" has a codepath to special case it to behave
differently from resetting to contents of other commits, but a
recent change broke it.
* Coloring around octopus merges in "log --graph" output was screwy.
(merge 339c17b hn/log-graph-color-octopus later to maint).
* "git checkout topic", when there is not yet a local "topic" branch
but there is a unique remote-tracking branch for a remote "topic"
branch, pretended as if "git checkout -t -b topic remote/$r/topic"
(for that unique remote $r) was run. This hack however was not
implemented for "git checkout topic --".
(merge bca3969 mm/checkout-auto-track-fix later to maint).
* One long-standing flaw in the pack transfer protocol used by "git
clone" was that there was no way to tell the other end which branch
"HEAD" points at, and the receiving end needed to guess. A new
capability has been defined in the pack protocol to convey this
information so that cloning from a repository with more than one
branches pointing at the same commit where the HEAD is at now
reliably sets the initial branch in the resulting repository.
(merge 360a326 jc/upload-pack-send-symref later to maint).
* We did not handle cases where http transport gets redirected during
the authorization request (e.g. from http:// to https://).
(merge 70900ed jk/http-auth-redirects later to maint).
* Bash prompting code to deal with an SVN remote as an upstream
were coded in a way not supported by older Bash versions (3.x).
(merge 52ec889 sg/prompt-svn-remote-fix later to maint).
* The fall-back parsing of commit objects with broken author or
committer lines were less robust than ideal in picking up the
timestamps.
(merge 03818a4 jk/split-broken-ident later to maint).
* "git rev-list --objects ^v1.0^ v1.0" gave v1.0 tag itself in the
output, but "git rev-list --objects v1.0^..v1.0" did not.
(merge 895c5ba jc/revision-range-unpeel later to maint).
* "git clone" gave some progress messages to the standard output, not
to the standard error, and did not allow suppressing them with the
--no-progress option.
(merge 643f918 jk/clone-progress-to-stderr later to maint).
* "format-patch --from=<whom>" forgot to omit unnecessary in-body
from line, i.e. when <whom> is the same as the real author.
(merge 662cc30 jk/format-patch-from later to maint).
* "git shortlog" used to choke and die when there is a malformed
commit (e.g. missing authors); it now simply ignore such a commit
and keeps going.
(merge cd4f09e jk/shortlog-tolerate-broken-commit later to maint).
* "git merge-recursive" did not parse its "--diff-algorithm=" command
line option correctly.
(merge 6562928 jk/diff-algo later to maint).
* When running "fetch -q", a long silence while the sender side
computes the set of objects to send can be mistaken by proxies as
dropped connection. The server side has been taught to send a
small empty messages to keep the connection alive.
(merge 115dedd jk/upload-pack-keepalive later to maint).
* "git rebase" had a portability regression in v1.8.4 to trigger a
bug in some BSD shell implementations.
(merge 99855dd mm/rebase-continue-freebsd-WB later to maint).
* "git branch --track" had a minor regression in v1.8.3.2 and later
that made it impossible to base your local work on anything but a
local branch of the upstream repository you are tracking from.
(merge b0f49ff jh/checkout-auto-tracking later to maint).
* When the webserver responds with "405 Method Not Allowed", "git
http-backend" should tell the client what methods are allowed with
the "Allow" header.
(merge 9247be0 bc/http-backend-allow-405 later to maint).
* When there is no sufficient overlap between old and new history
during a "git fetch" into a shallow repository, objects that the
sending side knows the receiving end has were unnecessarily sent.
(merge f21d2a7 nd/fetch-into-shallow later to maint).
* "git cvsserver" computed the permission mode bits incorrectly for
executable files.
(merge 1b48d56 jc/cvsserver-perm-bit-fix later to maint).
* When send-email comes up with an error message to die with upon
failure to start an SSL session, it tried to read the error string
from a wrong place.
(merge 6cb0c88 bc/send-email-ssl-die-message-fix later to maint).
* The implementation of "add -i" has a crippling code to work around
ActiveState Perl limitation but it by mistake also triggered on Git
for Windows where MSYS perl is used.
(merge df17e77 js/add-i-mingw later to maint).
* We made sure that we notice the user-supplied GIT_DIR is actually a
gitfile, but did not do the same when the default ".git" is a
gitfile.
(merge 487a2b7 nd/git-dir-pointing-at-gitfile later to maint).
* When an object is not found after checking the packfiles and then
loose object directory, read_sha1_file() re-checks the packfiles to
prevent racing with a concurrent repacker; teach the same logic to
has_sha1_file().
(merge 45e8a74 jk/has-sha1-file-retry-packed later to maint).
* "git commit --author=$name", when $name is not in the canonical
"A. U. Thor <au.thor@xxxxxxxxxx>" format, looks for a matching name
from existing history, but did not consult mailmap to grab the
preferred author name.
(merge ea16794 ap/commit-author-mailmap later to maint).
* "git ls-files -k" needs to crawl only the part of the working tree
that may overlap the paths in the index to find killed files, but
shared code with the logic to find all the untracked files, which
made it unnecessarily inefficient.
(merge 680be04 jc/ls-files-killed-optim later to maint).
* The commit object names in the insn sheet that was prepared at the
beginning of "rebase -i" session can become ambiguous as the
rebasing progresses and the repository gains more commits. Make
sure the internal record is kept with full 40-hex object names.
(merge 75c6976 es/rebase-i-no-abbrev later to maint).
* "git rebase --preserve-merges" internally used the merge machinery
and as a side effect, left merge summary message in the log, but
when rebasing, there should not be a need for merge summary.
(merge a9f739c rt/rebase-p-no-merge-summary later to maint).
* A call to xread() was used without a loop around to cope with short
read in the codepath to stream new contents to a pack.
(merge e92527c js/xread-in-full later to maint).
* "git rebase -i" forgot that the comment character can be
configurable while reading its insn sheet.
(merge 7bca7af es/rebase-i-respect-core-commentchar later to maint).
* The mailmap support code read past the allocated buffer when the
mailmap file ended with an incomplete line.
(merge f972a16 jk/mailmap-incomplete-line later to maint).
* We used to send a large request to read(2)/write(2) as a single
system call, which was bad from the latency point of view when
the operation needs to be killed, and also triggered an error on
broken 64-bit systems that refuse to take more than 2GB read or
write in one go.
(merge a487916 sp/clip-read-write-to-8mb later to maint).
* "git fetch" that auto-followed tags incorrectly reused the
connection with Git-aware transport helper (like the sample "ext::"
helper shipped with Git).
(merge 0f73f8b jc/transport-do-not-use-connect-twice-in-fetch later to maint).
* "git log --full-diff -- <pathspec>" showed a huge diff for paths
outside the given <pathspec> for each commit, instead of showing
the change relative to the parent of the commit. "git reflog -p"
had a similar problem.
(merge 838f9a1 tr/log-full-diff-keep-true-parents later to maint).
* Setting submodule.*.path configuration variable to true (without
giving "= value") caused Git to segfault.
(merge 4b05440 jl/some-submodule-config-are-not-boolean later to maint).
* "git rebase -i" (there could be others, as the root cause is pretty
generic) fed a random, data dependeant string to 'echo' and
expects it to come out literally, corrupting its error message.
(merge 89b0230 mm/no-shell-escape-in-die-message later to maint).
* Some people still use rather old versions of bash, which cannot
grok some constructs like 'printf -v varname' the prompt and
completion code started to use recently.
(merge a44aa69 bc/completion-for-bash-3.0 later to maint).
* Code to read configuration from a blob object did not compile on
platforms with fgetc() etc. implemented as macros.
(merge 49d6cfa hv/config-from-blob later to maint-1.8.3).
* The recent "short-cut clone connectivity check" topic broke a
shallow repository when a fetch operation tries to auto-follow tags.
(merge 6da8bdc nd/fetch-pack-shallow-fix later to maint-1.8.3).
