---------------------
* When "git am" is fed an input that has multiple "Content-type: ..."
header, it did not grok charset= attribute correctly.
* Even during a conflicted merge, "git blame $path" always meant to
blame uncommitted changes to the "working tree" version; make it
more useful by showing cleanly merged parts as coming from the other
branch that is being merged.
* "git blame MAKEFILE" run in a history that has "Makefile" but not
"MAKEFILE" should say "No such file MAKEFILE in HEAD", but got
confused on a case insensitive filesystem and failed to do so.
* "git fetch --all", when passed "--no-tags", did not honor the
"--no-tags" option while fetching from individual remotes (the same
issue existed with "--tags", but combination "--all --tags" makes
much less sense than "--all --no-tags").
* "git log/diff/format-patch --stat" showed the "N line(s) added"
comment in user's locale and caused careless submitters to send
patches with such a line in them to projects whose project language
is not their language, mildly irritating others. Localization to
the line has been disabled for now.
* "git log --all-match --grep=A --grep=B" ought to show commits that
mention both A and B, but when these three options are used with
--author or --committer, it showed commits that mention either A or
B (or both) instead.
* The subcommand to remove the definition of a remote in "git remote"
was named "rm" even though all other subcommands were spelled out.
Introduce "git remote remove" to remove confusion, and keep "rm" as
a backward compatible synonym.
Also contains a handful of documentation updates.
UI, Workflows & Features
* Git can be told to normalize pathnames it read from readdir(3) and
all arguments it got from the command line into precomposed UTF-8
(assuming that they come as decomposed UTF-8), in order to work
around issues on Mac OS.
I think there still are other places that need conversion
(e.g. paths that are read from stdin for some commands), but this
should be a good first step in the right direction.
* Per-user $HOME/.gitconfig file can optionally be stored in
$HOME/.config/git/config instead, which is in line with XDG.
* The value of core.attributesfile and core.excludesfile default to
$HOME/.config/git/attributes and $HOME/.config/git/ignore respectively
when these files exist.
* Logic to disambiguate abbreviated object names have been taught to
take advantage of object types that are expected in the context,
e.g. XXXXXX in the "git describe" output v1.2.3-gXXXXXX must be a
commit object, not a blob nor a tree. This will help us prolong
the lifetime of abbreviated object names.
* "git apply" learned to wiggle the base version and perform three-way
merge when a patch does not exactly apply to the version you have.
* Scripted Porcelain writers now have access to the credential API via
the "git credential" plumbing command.
* "git help" used to always default to "man" format even on platforms
where "man" viewer is not widely available.
* "git clone --local $path" started its life as an experiment to
optionally use link/copy when cloning a repository on the disk, but
we didn't deprecate it after we made the option a no-op to always
use the optimization. The command learned "--no-local" option to
turn this off, as a more explicit alternative over use of file://
URL.
* "git fetch" and friends used to say "remote side hung up
unexpectedly" when they failed to get response they expect from the
other side, but one common reason why they don't get expected
response is that the remote repository does not exist or cannot be
read. The error message in this case was updated to give better
hints to the user.
* "git help -w $cmd" can show HTML version of documentation for
"git-$cmd" by setting help.htmlpath to somewhere other than the
default location where the build procedure installs them locally;
the variable can even point at a http:// URL.
* "git rebase [-i] --root $tip" can now be used to rewrite all the
history leading to "$tip" down to the root commit.
* "git rebase -i" learned "-x <cmd>" to insert "exec <cmd>" after
each commit in the resulting history.
* "git status" gives finer classification to various states of paths
in conflicted state and offer advice messages in its output.
* "git submodule" learned to deal with nested submodule structure
where a module is contained within a module whose origin is
specified as a relative URL to its superproject's origin.
* A rather heavy-ish "git completion" script has been split to create
a separate "git prompting" script, to help lazy-autoloading of the
completion part while making prompting part always available.
* "gitweb" pays attention to various forms of credits that are
similar to "Signed-off-by:" lines in the commit objects and
highlights them accordingly.
* The cross links in the HTML version of manual pages were broken.
Also contains minor typofixes and documentation updates.
Changes 1.7.11:
UI, Workflows & Features
* A new mode for push, "simple", which is a cross between "current"
and "upstream", has been introduced. "git push" without any refspec
will push the current branch out to the same name at the remote
repository only when it is set to track the branch with the same
name over there. The plan is to make this mode the new default
value when push.default is not configured.
* A couple of commands learned the "--column" option to produce
columnar output.
* A third-party tool "git subtree" is distributed in contrib/
* A remote helper that acts as a proxy and caches ssl session for the
https:// transport is added to the contrib/ area.
* Error messages given when @{u} is used for a branch without its
upstream configured have been clarified.
* Even with the "-q"uiet option, "checkout" used to report setting up
tracking. Also "branch" learned the "-q"uiet option to squelch
informational message.
* Your build platform may support hardlinks but you may prefer not to
use them, e.g. when installing to DESTDIR to make a tarball and
untarring on a filesystem that has poor support for hardlinks.
There is a Makefile option NO_INSTALL_HARDLINKS for you.
* The smart-http backend used to always override GIT_COMMITTER_*
variables with REMOTE_USER and REMOTE_ADDR, but these variables are
now preserved when set.
* "git am" learned the "--include" option, which is an opposite of
existing the "--exclude" option.
* When "git am -3" needs to fall back to an application of the patch
to a synthesized preimage followed by a 3-way merge, the paths that
needed such treatment are now reported to the end user, so that the
result in them can be eyeballed with extra care.
* The output from "diff/log --stat" used to always allocate 4 columns
to show the number of modified lines, but not anymore.
* "git difftool" learned the "--dir-diff" option to spawn external
diff tools that can compare two directory hierarchies at a time
after populating two temporary directories, instead of running an
instance of the external tool once per a file pair.
* The "fmt-merge-msg" command learned to list the primary contributors
involved in the side topic you are merging in a comment in the merge
commit template.
* "git rebase" learned to optionally keep commits that do not
introduce any change in the original history.
* "git push --recurse-submodules" learned to optionally look into the
histories of submodules bound to the superproject and push them
out.
* A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
based on the commit date.
* "gitweb" learned to highlight the patch it outputs even more.
* gitk updates accumulated since early 2011.
* git-gui updated to 0.16.0.
* git-p4 (in contrib/) updates.
* Git uses gettext to translate its most common interface messages
into the user's language if translations are available and the
locale is appropriately set. Distributors can drop new PO files
in po/ to add new translations.
* The code to handle username/password for HTTP transactions used in
"git push" & "git fetch" learned to talk "credential API" to
external programs to cache or store them, to allow integration with
platform native keychain mechanisms.
* The input prompts in the terminal use our own getpass() replacement
when possible. HTTP transactions used to ask for the username without
echoing back what was typed, but with this change you will see it as
you type.
* The internals of "revert/cherry-pick" have been tweaked to prepare
building more generic "sequencer" on top of the implementation that
drives them.
* "git rev-parse FETCH_HEAD" after "git fetch" without specifying
what to fetch from the command line will now show the commit that
would be merged if the command were "git pull".
* "git add" learned to stream large files directly into a packfile
instead of writing them into individual loose object files.
* "git checkout -B <current branch> <elsewhere>" is a more intuitive
way to spell "git reset --keep <elsewhere>".
* "git checkout" and "git merge" learned "--no-overwrite-ignore" option
to tell Git that untracked and ignored files are not expendable.
* "git commit --amend" learned "--no-edit" option to say that the
user is amending the tree being recorded, without updating the
commit log message.
* "git commit" and "git reset" re-learned the optimization to prime
the cache-tree information in the index, which makes it faster to
write a tree object out after the index entries are updated.
* "git commit" detects and rejects an attempt to stuff NUL byte in
the commit log message.
* "git commit" learned "-S" to GPG-sign the commit; this can be shown
with the "--show-signature" option to "git log".
* fsck and prune are relatively lengthy operations that still go
silent while making the end-user wait. They learned to give progress
output like other slow operations.
* The set of built-in function-header patterns for various languages
knows MATLAB.
* "git log --format='<format>'" learned new %g[nNeE] specifiers to
show information from the reflog entries when walking the reflog
(i.e. with "-g").
* "git pull" can be used to fetch and merge an annotated/signed tag,
instead of the tip of a topic branch. The GPG signature from the
signed tag is recorded in the resulting merge commit for later
auditing.
* "git log" learned "--show-signature" option to show the signed tag
that was merged that is embedded in the merge commit. It also can
show the signature made on the commit with "git commit -S".
* "git branch --edit-description" can be used to add descriptive text
to explain what a topic branch is about.
* "git fmt-merge-msg" learned to take the branch description into
account when preparing a merge summary that "git merge" records
when merging a local branch.
* "git request-pull" has been updated to convey more information
useful for integrators to decide if a topic is worth merging and
what is pulled is indeed what the requestor asked to pull,
including:
- the tip of the branch being requested to be merged;
- the branch description describing what the topic is about;
- the contents of the annotated tag, when requesting to pull a tag.
* "git pull" learned to notice 'pull.rebase' configuration variable,
which serves as a global fallback for setting 'branch.<name>.rebase'
configuration variable per branch.
* "git tag" learned "--cleanup" option to control how the whitespaces
and empty lines in tag message are cleaned up.
* "gitweb" learned to show side-by-side diff.
* The code to look up attributes for paths reused entries from a wrong
directory when two paths in question are in adjacent directories and
the name of the one directory is a prefix of the other.
* A wildcard that matches deeper hierarchy given to the "diff-index" command,
e.g. "git diff-index HEAD -- '*.txt'", incorrectly reported additions of
matching files even when there is no change.
* When producing a "thin pack" (primarily used in bundles and smart
HTTP transfers) out of a fully packed repository, we unnecessarily
avoided sending recent objects as a delta against objects we know
the other side has.
* "git send-email" did not properly treat sendemail.multiedit as a
boolean (e.g. setting it to "false" did not turn it off).
* Also contains minor fixes and documentation updates.
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Interix, Cygwin and Minix ports got updated.
* Various updates to git-p4 (in contrib/), fast-import, and git-svn.
* Gitweb learned to read from /etc/gitweb-common.conf when it exists,
before reading from gitweb_config.perl or from /etc/gitweb.conf
* Various codepaths that invoked zlib deflate/inflate assumed that these
functions can compress or uncompress more than 4GB data in one call on
platforms with 64-bit long, which has been corrected.
* Git now recognizes loose objects written by other implementations that
use a non-standard window size for zlib deflation (e.g. Agit running on
Android with 4kb window). We used to reject anything that was not
deflated with 32kb window.
* Interaction between the use of pager and coloring of the output has
been improved, especially when a command that is not built-in was
involved.
* "git am" learned to pass the "--exclude=<path>" option through to underlying
"git apply".
* You can now feed many empty lines before feeding an mbox file to "git am".
* "git archive" can be told to pass the output to gzip compression and
produce "archive.tar.gz".
* "git bisect" can be used in a bare repository (provided that the test
you perform per each iteration does not need a working tree, of course).
* The length of abbreviated object names in "git branch -v" output
now honors the core.abbrev configuration variable.
* "git check-attr" can take relative paths from the command line.
* "git check-attr" learned an "--all" option to list the attributes for a
given path.
* "git checkout" (both the code to update the files upon checking out a
different branch and the code to checkout a specific set of files) learned
to stream the data from object store when possible, without having to
read the entire contents of a file into memory first. An earlier round
of this code that is not in any released version had a large leak but
now it has been plugged.
* "git clone" can now take a "--config key=value" option to set the
repository configuration options that affect the initial checkout.
* "git commit <paths>..." now lets you feed relative pathspecs that
refer to outside your current subdirectory.
* "git diff --stat" learned a --stat-count option to limit the output of
a diffstat report.
* "git diff" learned a "--histogram" option to use a different diff
generation machinery stolen from jgit, which might give better performance.
* "git diff" had a weird worst case behaviour that can be triggered
when comparing files with potentially many places that could match.
* "git fetch", "git push" and friends no longer show connection
errors for addresses that couldn't be connected to when at least one
address succeeds (this is arguably a regression but a deliberate one).
* "git grep" learned "--break" and "--heading" options, to let users mimic
the output format of "ack".
* "git grep" learned a "-W" option that shows wider context using the same
logic used by "git diff" to determine the hunk header.
* Invoking the low-level "git http-fetch" without "-a" option (which
git itself never did---normal users should not have to worry about
this) is now deprecated.
* The "--decorate" option to "git log" and its family learned to
highlight grafted and replaced commits.
* "git rebase master topci" no longer spews usage hints after giving
the "fatal: no such branch: topci" error message.
* The recursive merge strategy implementation got a fairly large
fix for many corner cases that may rarely happen in real world
projects (it has been verified that none of the 16000+ merges in
the Linux kernel history back to v2.6.12 is affected with the
corner case bugs this update fixes).
* "git stash" learned an "--include-untracked option".
* "git submodule update" used to stop at the first error updating a
submodule; it now goes on to update other submodules that can be
updated, and reports the ones with errors at the end.
* "git push" can be told with the "--recurse-submodules=check" option to
refuse pushing of the supermodule, if any of its submodules'
commits hasn't been pushed out to their remotes.
* "git upload-pack" and "git receive-pack" learned to pretend that only a
subset of the refs exist in a repository. This may help a site to
put many tiny repositories into one repository (this would not be
useful for larger repositories as repacking would be problematic).
* "git verify-pack" has been rewritten to use the "index-pack" machinery
that is more efficient in reading objects in packfiles.
* test scripts for gitweb tried to run even when CGI-related perl modules
are not installed; they now exit early when the latter are unavailable.
* Various git-svn updates.
* Updates the way content tags are handled in gitweb. Also adds
a UI to choose common timezone for displaying the dates.
* Similar to branch names, tagnames that begin with "-" are now
disallowed.
* Clean-up of the C part of i18n (but not l10n---please wait)
continues.
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Pushing and pulling from a repository with large number of refs that
point to identical commits are optimized by not listing the same commit
during the common ancestor negotiation exchange with the other side.
* Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
using "git add" will send the contents straight to a packfile without
having to hold it and its compressed representation both at the same
time in memory.
* Processes spawned by "[alias] <name> = !process" in the configuration
can inspect GIT_PREFIX environment variable to learn where in the
working tree the original command was invoked.
* A magic pathspec ":/" tells a command that limits its operation to
the current directory when ran from a subdirectory to work on the
entire working tree. In general, ":/path/to/file" would be relative
to the root of the working tree hierarchy.
After "git reset --hard; edit Makefile; cd t/", "git add -u" would
be a no-op, but "git add -u :/" would add the updated contents of
the Makefile at the top level. If you want to name a path in the
current subdirectory whose unusual name begins with ":/", you can
name it by "./:/that/path" or by "\:/that/path".
* "git blame" learned "--abbrev[=<n>]" option to control the minimum
number of hexdigits shown for commit object names.
* "git blame" learned "--line-porcelain" that is less efficient but is
easier to parse.
* Aborting "git commit --interactive" discards updates to the index
made during the interactive session.
* More...
* "git apply" used to confuse lines updated by previous hunks as lines
that existed before when applying a hunk, contributing misapplication
of patches with offsets.
* "git branch --track" (and "git checkout --track --branch") used to
allow setting up a random non-branch that does not make sense to follow
as the "upstream". The command correctly diagnoses it as an error.
* "git checkout $other_branch" silently removed untracked symbolic links
in the working tree that are in the way in order to check out paths
under it from the named branch.
* "git cvsimport" did not bail out immediately when the cvs server cannot
be reached, spewing unnecessary error messages that complain about the
server response that it never got.
* "git diff --quiet" did not work very well with the "--diff-filter" option.
* "git grep -n" lacked a long-hand synonym --line-number.
* "git stash apply" reported the result of its operation by running
"git status" from the top-level of the working tree; it should (and
now does) run it from the user's working directory.
* On Windows platform, the codepath to spawn a new child process forgot
to first flush the output buffer.
* "git bundle" did not use OFS_DELTA encoding, making its output a few
per-cent larger than necessarily.
* The option to tell "git clone" to recurse into the submodules was
misspelled with an underscore "--recurse_submodules".
* "git diff --cached HEAD" before the first commit does what an end user
would expect (namely, show what would be committed without further "git
add").
* "git fast-import" didn't accept the command to ask for "notes" feature
to be present in its input stream, even though it was capable of the
feature.
* "git fsck" gave up scanning loose object files in directories with
garbage files.
This is primarily to push out many documentation fixes accumulated since
the 1.7.3.1 release.
Changes 1.7.3.1:
* "git stash show stash@{$n}" was accidentally broken in 1.7.3 ("git
stash show" without any argument still worked, though).
* "git stash branch $branch stash@{$n}" was accidentally broken in
1.7.3 and started dropping the named stash even when branch creation
failed.
Changes 1.7.3:
* git-gui, now at version 0.13.0, got various updates and a new
maintainer, Pat Thoyts.
* Gitweb allows its configuration to change per each request; it used to
read the configuration once upon startup.
* When git finds a corrupt object, it now reports the file that contains
it.
* "git checkout -B <it>" is a shorter way to say "git branch -f <it>"
followed by "git checkout <it>".
* When "git checkout" or "git merge" refuse to proceed in order to
protect local modification to your working tree, they used to stop
after showing just one path that might be lost. They now show all,
in a format that is easier to read.
* "git clean" learned "-e" ("--exclude") option.
* Hunk headers produced for C# files by "git diff" and friends show more
relevant context than before.
* diff.ignoresubmodules configuration variable can be used to squelch the
differences in submodules reported when running commands (e.g. "diff",
"status", etc.) at the superproject level.
* http.useragent configuration can be used to lie who you are to your
restrictive firewall.
* "git rebase --strategy <s>" learned "-X" option to pass extra options
that are understood by the chosen merge strategy.
* "git rebase -i" learned "exec" that you can insert into the insn sheet
to run a command between its steps.
* "git rebase" between branches that have many binary changes that do
not conflict should be faster.
* "git rebase -i" peeks into rebase.autosquash configuration and acts as
if you gave --autosquash from the command line.
Git v1.6.6 Release Notes
========================
Notes on behaviour change
-------------------------
* In this release, "git fsck" defaults to "git fsck --full" and
checks packfiles, and because of this it will take much longer to
complete than before. If you prefer a quicker check only on loose
objects (the old default), you can say "git fsck --no-full". This
has been supported by 1.5.4 and newer versions of git, so it is
safe to write it in your script even if you use slightly older git
on some of your machines.
Preparing yourselves for compatibility issues in 1.7.0
------------------------------------------------------
In git 1.7.0, which is planned to be the release after 1.6.6, there will
be a handful of behaviour changes that will break backward compatibility.
These changes were discussed long time ago and existing behaviours have
been identified as more problematic to the userbase than keeping them for
the sake of backward compatibility.
When necessary, a transition strategy for existing users has been designed
not to force them running around setting configuration variables and
updating their scripts in order to either keep the traditional behaviour
or adjust to the new behaviour, on the day their sysadmin decides to install
the new version of git. When we switched from "git-foo" to "git foo" in
1.6.0, even though the change had been advertised and the transition
guide had been provided for a very long time, the users procrastinated
during the entire transtion period, and ended up panicking on the day
their sysadmins updated their git installation. We are trying to avoid
repeating that unpleasantness in the 1.7.0 release.
For changes decided to be in 1.7.0, commands that will be affected
have been much louder to strongly discourage such procrastination, and
they continue to be in this release. If you have been using recent
versions of git, you would have seen warnings issued when you used
features whose behaviour will change, with a clear instruction on how
to keep the existing behaviour if you want to. You hopefully are
already well prepared.
Of course, we have also been giving "this and that will change in
1.7.0; prepare yourselves" warnings in the release notes and
announcement messages for the past few releases. Let's see how well
users will fare this time.
* "git push" into a branch that is currently checked out (i.e. pointed by
HEAD in a repository that is not bare) will be refused by default.
Similarly, "git push $there :$killed" to delete the branch $killed
in a remote repository $there, when $killed branch is the current
branch pointed at by its HEAD, will be refused by default.
Setting the configuration variables receive.denyCurrentBranch and
receive.denyDeleteCurrent to 'ignore' in the receiving repository
can be used to override these safety features. Versions of git
since 1.6.2 have issued a loud warning when you tried to do these
operations without setting the configuration, so repositories of
people who still need to be able to perform such a push should
already have been future proofed.
Please refer to:
http://git.or.cz/gitwiki/GitFaq#non-barehttp://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
for more details on the reason why this change is needed and the
transition process that already took place so far.
* "git send-email" will not make deep threads by default when sending a
patch series with more than two messages. All messages will be sent
as a reply to the first message, i.e. cover letter. Git 1.6.6 (this
release) will issue a warning about the upcoming default change, when
it uses the traditional "deep threading" behaviour as the built-in
default. To squelch the warning but still use the "deep threading"
behaviour, give --chain-reply-to option or set sendemail.chainreplyto
to true.
It has been possible to configure send-email to send "shallow thread"
by setting sendemail.chainreplyto configuration variable to false.
The only thing 1.7.0 release will do is to change the default when
you haven't configured that variable.
* "git status" will not be "git commit --dry-run". This change does not
affect you if you run the command without pathspec.
Nobody sane found the current behaviour of "git status Makefile" useful
nor meaningful, and it confused users. "git commit --dry-run" has been
provided as a way to get the current behaviour of this command since
1.6.5.
* "git diff" traditionally treated various "ignore whitespace" options
only as a way to filter the patch output. "git diff --exit-code -b"
exited with non-zero status even if all changes were about changing the
ammount of whitespace and nothing else. and "git diff -b" showed the
"diff --git" header line for such a change without patch text.
In 1.7.0, the "ignore whitespaces" will affect the semantics of the
diff operation itself. A change that does not affect anything but
whitespaces will be reported with zero exit status when run with
--exit-code, and there will not be "diff --git" header for such a
change.
Updates since v1.6.5
--------------------
(subsystems)
* various gitk updates including use of themed widgets under Tk 8.5,
Japanese translation, a fix to a bug when running "gui blame" from
a subdirectory, etc.
* various git-gui updates including new translations, wm states fixes,
Tk bug workaround after quitting, improved heuristics to trigger gc,
etc.
* various git-svn updates.
* "git fetch" over http learned a new mode that is different from the
traditional "dumb commit walker".
(portability)
* imap-send can be built on mingw port.
(performance)
* "git diff -B" has smaller memory footprint.
(usability, bells and whistles)
* The object replace mechanism can be bypassed with --no-replace-objects
global option given to the "git" program.
* In configuration files, a few variables that name paths can begin with ~/
and ~username/ and they are expanded as expected.
* "git subcmd -h" now shows short usage help for many more subcommands.
* "git bisect reset" can reset to an arbitrary commit.
* "git checkout frotz" when there is no local branch "frotz" but there
is only one remote tracking branch "frotz" is taken as a request to
start the named branch at the corresponding remote tracking branch.
* "git commit -c/-C/--amend" can be told with a new "--reset-author" option
to ignore authorship information in the commit it is taking the message
from.
* "git describe" can be told to add "-dirty" suffix with "--dirty" option.
* "git diff" learned --submodule option to show a list of one-line logs
instead of differences between the commit object names.
* "git diff" learned to honor diff.color.func configuration to paint
function name hint printed on the hunk header "@@ -j,k +l,m @@" line
in the specified color.
* "git fetch" learned --all and --multiple options, to run fetch from
many repositories, and --prune option to remove remote tracking
branches that went stale. These make "git remote update" and "git
remote prune" less necessary (there is no plan to remove "remote
update" nor "remote prune", though).
* "git fsck" by default checks the packfiles (i.e. "--full" is the
default); you can turn it off with "git fsck --no-full".
* "git grep" can use -F (fixed strings) and -i (ignore case) together.
* import-tars contributed fast-import frontend learned more types of
compressed tarballs.
* "git instaweb" knows how to talk with mod_cgid to apache2.
* "git log --decorate" shows the location of HEAD as well.
* "git log" and "git rev-list" learned to take revs and pathspecs from
the standard input with the new "--stdin" option.
* "--pretty=format" option to "log" family of commands learned:
. to wrap text with the "%w()" specifier.
. to show reflog information with "%g[sdD]" specifier.
* "git notes" command to annotate existing commits.
* "git merge" (and "git pull") learned --ff-only option to make it fail
if the merge does not result in a fast-forward.
* "git mergetool" learned to use p4merge.
* "git rebase -i" learned "reword" that acts like "edit" but immediately
starts an editor to tweak the log message without returning control to
the shell, which is done by "edit" to give an opportunity to tweak the
contents.
* "git send-email" can be told with "--envelope-sender=auto" to use the
same address as "From:" address as the envelope sender address.
* "git send-email" will issue a warning when it defaults to the
--chain-reply-to behaviour without being told by the user and
instructs to prepare for the change of the default in 1.7.0 release.
* In "git submodule add <repository> <path>", <path> is now optional and
inferred from <repository> the same way "git clone <repository>" does.
* "git svn" learned to read SVN 1.5+ and SVK merge tickets.
* "git svn" learned to recreate empty directories tracked only by SVN.
* "gitweb" can optionally render its "blame" output incrementally (this
requires JavaScript on the client side).
* Author names shown in gitweb output are links to search commits by the
author.
Fixes since v1.6.5
------------------
All of the fixes in v1.6.5.X maintenance series are included in this
release, unless otherwise noted.
GIT v1.6.5 Release Notes
========================
In git 1.7.0, which was planned to be the release after 1.6.5, "git
push" into a branch that is currently checked out will be refused by
default.
You can choose what should happen upon such a push by setting the
configuration variable receive.denyCurrentBranch in the receiving
repository.
Also, "git push $there :$killed" to delete the branch $killed in a remote
repository $there, when $killed branch is the current branch pointed at by
its HEAD, will be refused by default.
You can choose what should happen upon such a push by setting the
configuration variable receive.denyDeleteCurrent in the receiving
repository.
To ease the transition plan, the receiving repository of such a
push running this release will issue a big warning when the
configuration variable is missing. Please refer to:
http://git.or.cz/gitwiki/GitFaq#non-barehttp://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
for more details on the reason why this change is needed and the
transition plan.
Updates since v1.6.4
--------------------
(subsystems)
* various updates to gitk, git-svn and gitweb.
(portability)
* more improvements on mingw port.
* mingw will also give FRSX as the default value for the LESS
environment variable when the user does not have one.
* initial support to compile git on Windows with MSVC.
(performance)
* On major platforms, the system can be compiled to use with Linus's
block-sha1 implementation of the SHA-1 hash algorithm, which
outperforms the default fallback implementation we borrowed from
Mozilla.
* Unnecessary inefficiency in deepening of a shallow repository has
been removed.
* "git clone" does not grab objects that it does not need (i.e.
referenced only from refs outside refs/heads and refs/tags
hierarchy) anymore.
* The "git" main binary used to link with libcurl, which then dragged
in a large number of external libraries. When using basic plumbing
commands in scripts, this unnecessarily slowed things down. We now
implement http/https/ftp transfer as a separate executable as we
used to.
* "git clone" run locally hardlinks or copies the files in .git/ to
newly created repository. It used to give new mtime to copied files,
but this delayed garbage collection to trigger unnecessarily in the
cloned repository. We now preserve mtime for these files to avoid
this issue.
(usability, bells and whistles)
* Human writable date format to various options, e.g. --since=yesterday,
master@{2000.09.17}, are taught to infer some omitted input properly.
* A few programs gave verbose "advice" messages to help uninitiated
people when issuing error messages. An infrastructure to allow
users to squelch them has been introduced, and a few such messages
can be silenced now.
* refs/replace/ hierarchy is designed to be usable as a replacement
of the "grafts" mechanism, with the added advantage that it can be
transferred across repositories.
* "git am" learned to optionally ignore whitespace differences.
* "git am" handles input e-mail files that has CRLF line endings sensibly.
* "git am" learned "--scissors" option to allow you to discard early part
of an incoming e-mail.
* "git archive -o output.zip" works without being told what format to
use with an explicit "--format=zip".option.
* "git checkout", "git reset" and "git stash" learned to pick and
choose to use selected changes you made, similar to "git add -p".
* "git clone" learned a "-b" option to pick a HEAD to check out
different from the remote's default branch.
* "git clone" learned --recursive option.
* "git clone" from a local repository on a different filesystem used to
copy individual object files without preserving the old timestamp, giving
them extra lifetime in the new repository until they gc'ed.
* "git commit --dry-run $args" is a new recommended way to ask "what would
happen if I try to commit with these arguments."
* "git commit --dry-run" and "git status" shows conflicted paths in a
separate section to make them easier to spot during a merge.
* "git cvsimport" now supports password-protected pserver access even
when the password is not taken from ~/.cvspass file.
* "git fast-export" learned --no-data option that can be useful when
reordering commits and trees without touching the contents of
blobs.
* "git fast-import" has a pair of new front-end in contrib/ area.
* "git init" learned to mkdir/chdir into a directory when given an
extra argument (i.e. "git init this").
* "git instaweb" optionally can use mongoose as the web server.
* "git log --decorate" can optionally be told with --decorate=full to
give the reference name in full.
* "git merge" issued an unnecessarily scary message when it detected
that the merge may have to touch the path that the user has local
uncommitted changes to. The message has been reworded to make it
clear that the command aborted, without doing any harm.
* "git push" can be told to be --quiet.
* "git push" pays attention to url.$base.pushInsteadOf and uses a URL
that is derived from the URL used for fetching.
* informational output from "git reset" that lists the locally modified
paths is made consistent with that of "git checkout $another_branch".
* "git submodule" learned to give submodule name to scripts run with
"foreach" subcommand.
* various subcommands to "git submodule" learned --recursive option.
* "git submodule summary" learned --files option to compare the work
tree vs the commit bound at submodule path, instead of comparing
the index.
* "git upload-pack", which is the server side support for "git clone" and
"git fetch", can call a new post-upload-pack hook for statistics purposes.
(developers)
* With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
source directory; using tmpfs may give faster turnaround.
* With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
build for one location, and install into another location to tar it
up.
Fixes since v1.6.4
------------------
All of the fixes in v1.6.4.X maintenance series are included in this
release, unless otherwise noted.
This version fixes the remote DoS problem in
http://secunia.com/advisories/35437/.
Major changes between 1.6.2 and 1.6.3:
* various git-svn updates.
* git-gui updates, including an update to Russian translation, and a
fix to an infinite loop when showing an empty diff.
* gitk updates, including an update to Russian translation and
improved Windows support.
* many uses of lstat(2) in the codepath for "git checkout" have been
optimized out.
* usuability improvements.
* bug fixes.
Major changes in 1.6.1:
When some commands (e.g. "git log", "git diff") spawn pager
internally, we used to make the pager the parent process of the git
command that produces output. This meant that the exit status of the
whole thing comes from the pager, not the underlying git command. We
swapped the order of the processes around and you will see the exit
code from the command from now on.
Major changes in 1.6.2:
With the next major release, "git push" into a branch that is
currently checked out will be refused by default. You can choose what
should happen upon such a push by setting the configuration variable
receive.denyCurrentBranch in the receiving repository.
To ease the transition plan, the receiving repository of such a push
running this release will issue a big warning when the configuration
variable is missing.
For a similar reason, "git push $there :$killed" to delete the branch
$killed in a remote repository $there, if $killed branch is the
current branch pointed at by its HEAD, gets a large warning. You can
choose what should happen upon such a push by setting the
configuration variable receive.denyDeleteCurrent in the receiving
repository.
change ${.CURDIR}/../... to ../../devel/scmgit/...; makes
a lot more sense.
Fixes since v1.6.0.1
--------------------
* Installation on platforms that needs .exe suffix to git-* programs were
broken in 1.6.0.1.
* Installation on filesystems without symbolic links support did nto
work well.
* In-tree documentations and test scripts now use "git foo" form to set a
better example, instead of the "git-foo" form (which is an acceptable
form if you have "PATH=$(git --exec-path):$PATH" in your script)
* Many commands did not use the correct working tree location when used
with GIT_WORK_TREE environment settings.
* Some systems needs to use compatibility fnmach and regex libraries
independent from each other; the compat/ area has been reorganized to
allow this.
* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
a new line before the second line.
* "git blame -c" did not exactly work like "git annotate" when range
boundaries are involved.
* "git checkout file" when file is still unmerged checked out contents from
a random high order stage, which was confusing.
* "git clone $there $here/" with extra trailing slashes after explicit
local directory name $here did not work as expected.
* "git diff" on tracked contents with CRLF line endings did not drive "less"
intelligently when showing added or removed lines.
* "git diff --dirstat -M" did not add changes in subdirectories up
correctly for renamed paths.
* "git diff --cumulative" did not imply "--dirstat".
* "git for-each-ref refs/heads/" did not work as expected.
* "git gui" allowed users to feed patch without any context to be applied.
* "git gui" botched parsing "diff" output when a line that begins with two
dashes and a space gets removed or a line that begins with two pluses
and a space gets added.
* "git gui" translation updates and i18n fixes.
* "git index-pack" is more careful against disk corruption while completing
a thin pack.
* "git log -i --grep=pattern" did not ignore case; neither "git log -E
--grep=pattern" triggered extended regexp.
* "git log --pretty="%ad" --date=short" did not use short format when
showing the timestamp.
* "git log --author=author" match incorrectly matched with the
timestamp part of "author " line in commit objects.
* "git log -F --author=author" did not work at all.
* Build procedure for "git shell" that used stub versions of some
functions and globals was not understood by linkers on some platforms.
* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
and refused to work until the user refreshed the index.
* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
use of temporary files.
* "git verify-pack -v" did not work correctly when given more than one
packfile.
Also contains many documentation updates.
GIT v1.5.6 Release Notes
========================
Updates since v1.5.5
--------------------
(subsystems)
* Comes with updated gitk and git-gui.
(portability)
* git will build on AIX better than before now.
* core.ignorecase configuration variable can be used to work better on
filesystems that are not case sensitive.
* "git init" now autodetects the case sensitivity of the filesystem and
sets core.ignorecase accordingly.
* cpio is no longer used; neither "curl" binary (libcurl is still used).
(documentation)
* Many freestanding documentation pages have been converted and made
available to "git help" (aka "man git<something>") as section 7 of
the manual pages. This means bookmarks to some HTML documentation
files may need to be updated (eg "tutorial.html" became
"gittutorial.html").
(performance)
* "git clone" was rewritten in C. This will hopefully help cloning a
repository with insane number of refs.
* "git rebase --onto $there $from $branch" used to switch to the tip of
$branch only to immediately reset back to $from, smudging work tree
files unnecessarily. This has been optimized.
* Object creation codepath in "git-svn" has been optimized by enhancing
plumbing commands git-cat-file and git-hash-object.
(usability, bells and whistles)
* "git add -p" (and the "patch" subcommand of "git add -i") can choose to
apply (or not apply) mode changes independently from contents changes.
* "git bisect help" gives longer and more helpful usage information.
* "git bisect" does not use a special branch "bisect" anymore; instead, it
does its work on a detached HEAD.
* "git branch" (and "git checkout -b") can be told to set up
branch.<name>.rebase automatically, so that later you can say "git pull"
and magically cause "git pull --rebase" to happen.
* "git branch --merged" and "git branch --no-merged" can be used to list
branches that have already been merged (or not yet merged) to the
current branch.
* "git cherry-pick" and "git revert" can add a sign-off.
* "git commit" mentions the author identity when you are committing
somebody else's changes.
* "git diff/log --dirstat" output is consistent between binary and textual
changes.
* "git filter-branch" rewrites signed tags by demoting them to annotated.
* "git format-patch --no-binary" can produce a patch that lack binary
changes (i.e. cannot be used to propagate the whole changes) meant only
for reviewing.
* "git init --bare" is a synonym for "git --bare init" now.
* "git gc --auto" honors a new pre-auto-gc hook to temporarily disable it.
* "git log --pretty=tformat:<custom format>" gives a LF after each entry,
instead of giving a LF between each pair of entries which is how
"git log --pretty=format:<custom format>" works.
* "git log" and friends learned the "--graph" option to show the ancestry
graph at the left margin of the output.
* "git log" and friends can be told to use date format that is different
from the default via 'log.date' configuration variable.
* "git send-email" now can send out messages outside a git repository.
* "git send-email --compose" was made aware of rfc2047 quoting.
* "git status" can optionally include output from "git submodule
summary".
* "git svn" learned --add-author-from option to propagate the authorship
by munging the commit log message.
* new object creation and looking up in "git svn" has been optimized.
* "gitweb" can read from a system-wide configuration file.
(internal)
* "git unpack-objects" and "git receive-pack" is now more strict about
detecting breakage in the objects they receive over the wire.
The scmgit-base package now installs most of its binaries, e.g. git-*,
to ${PREFIX}/libexec/git-core/ instead of ${PREFIX}/bin. There are
only two programs under ${LOCALBASE}/bin: the "master" git(7) wrapper
program and the gitk tcl/tk repository browser. Given that there are
many different GIT interfaces (GUI applications, devel/tig, shell
completion scripts, etc.), it seemed needless to me to have 120+
binaries--a vast majority of which most users would seldom invoke
directly--polluting ${LOCALBASE}/bin.
GIT v1.5.5 Release Notes
========================
Updates since v1.5.4
--------------------
(subsystems)
* Comes with git-gui 0.10.1
(portability)
* We shouldn't ask for BSD group ownership semantics by setting g+s bit
on directories on older BSD systems that refuses chmod() by non root
users. BSD semantics is the default there anyway.
* Bunch of portability improvement patches coming from an effort to port
to Solaris has been applied.
(performance)
* On platforms with suboptimal qsort(3) implementation, there
is an option to use more reasonable substitute we ship with
our software.
* New configuration variable "pack.packsizelimit" can be used
in place of command line option --max-pack-size.
* "git fetch" over the native git protocol used to make a
connection to find out the set of current remote refs and
another to actually download the pack data. We now use only
one connection for these tasks.
* "git commit" does not run lstat(2) more than necessary
anymore.
(usability, bells and whistles)
* Bash completion script (in contrib) are aware of more commands and
options.
* You can be warned when core.autocrlf conversion is applied in
such a way that results in an irreversible conversion.
* A catch-all "color.ui" configuration variable can be used to
enable coloring of all color-capable commands, instead of
individual ones such as "color.status" and "color.branch".
* The commands refused to take absolute pathnames where they
require pathnames relative to the work tree or the current
subdirectory. They now can take absolute pathnames in such a
case as long as the pathnames do not refer outside of the
work tree. E.g. "git add $(pwd)/foo" now works.
* Error messages used to be sent to stderr, only to get hidden,
when $PAGER was in use. They now are sent to stdout along
with the command output to be shown in the $PAGER.
* A pattern "foo/" in .gitignore file now matches a directory
"foo". Pattern "foo" also matches as before.
* bash completion's prompt helper function can talk about
operation in-progress (e.g. merge, rebase, etc.).
* Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
used to tell "git-fetch" and "git-push" to use different URL than what
is given from the command line.
* "git add -i" behaves better even before you make an initial commit.
* "git am" refused to run from a subdirectory without a good reason.
* After "git apply --whitespace=fix" fixes whitespace errors in a patch,
a line before the fix can appear as a context or preimage line in a
later patch, causing the patch not to apply. The command now knows to
see through whitespace fixes done to context lines to successfully
apply such a patch series.
* "git branch" (and "git checkout -b") to branch from a local branch can
optionally set "branch.<name>.merge" to mark the new branch to build on
the other local branch, when "branch.autosetupmerge" is set to
"always", or when passing the command line option "--track" (this option
was ignored when branching from local branches). By default, this does
not happen when branching from a local branch.
* "git checkout" to switch to a branch that has "branch.<name>.merge" set
(i.e. marked to build on another branch) reports how much the branch
and the other branch diverged.
* When "git checkout" has to update a lot of paths, it used to be silent
for 4 seconds before it showed any progress report. It is now a bit
more impatient and starts showing progress report early.
* "git commit" learned a new hook "prepare-commit-msg" that can
inspect what is going to be committed and prepare the commit
log message template to be edited.
* "git cvsimport" can now take more than one -M options.
* "git describe" learned to limit the tags to be used for
naming with --match option.
* "git describe --contains" now barfs when the named commit
cannot be described.
* "git describe --exact-match" describes only commits that are tagged.
* "git describe --long" describes a tagged commit as $tag-0-$sha1,
instead of just showing the exact tagname.
* "git describe" warns when using a tag whose name and path contradict
with each other.
* "git diff" learned "--relative" option to limit and output paths
relative to the current directory when working in a subdirectory.
* "git diff" learned "--dirstat" option to show birds-eye-summary of
changes more concisely than "--diffstat".
* "git format-patch" learned --cover-letter option to generate a cover
letter template.
* "git gc" learned --quiet option.
* "git gc" now automatically prunes unreachable objects that are two
weeks old or older.
* "git gc --auto" can be disabled more easily by just setting gc.auto
to zero. It also tolerates more packfiles by default.
* "git grep" now knows "--name-only" is a synonym for the "-l" option.
* "git help <alias>" now reports "'git <alias>' is alias to <what>",
instead of saying "No manual entry for git-<alias>".
* "git help" can use different backends to show manual pages and this can
be configured using "man.viewer" configuration.
* "gitk" does not restore window position from $HOME/.gitk anymore (it
still restores the size).
* "git log --grep=<what>" learned "--fixed-strings" option to look for
<what> without treating it as a regular expression.
* "git gui" learned an auto-spell checking.
* "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
expected; they push the current branch (and only the current branch).
In addition, HEAD can be written as the value of "remote.<there>.push"
configuration variable.
* When the configuration variable "pack.threads" is set to 0, "git
repack" auto detects the number of CPUs and uses that many threads.
* "git send-email" learned to prompt for passwords
interactively.
* "git send-email" learned an easier way to suppress CC
recipients.
* "git stash" learned "pop" command, that applies the latest stash and
removes it from the stash, and "drop" command to discard the named
stash entry.
* "git submodule" learned a new subcommand "summary" to show the
symmetric difference between the HEAD version and the work tree version
of the submodule commits.
* Various "git cvsimport", "git cvsexportcommit", "git cvsserver",
"git svn" and "git p4" improvements.
(internal)
* Duplicated code between git-help and git-instaweb that
launches user's preferred browser has been refactored.
* It is now easier to write test scripts that records known
breakages.
* "git checkout" is rewritten in C.
* "git remote" is rewritten in C.
* Two conflict hunks that are separated by a very short span of common
lines are now coalesced into one larger hunk, to make the result easier
to read.
* Run-command API's use of file descriptors is documented clearer and
is more consistent now.
* diff output can be sent to FILE * that is different from stdout. This
will help reimplementing more things in C.
Fixes since v1.5.4
------------------
All of the fixes in v1.5.4 maintenance series are included in
this release, unless otherwise noted.
* "git-http-push" did not allow deletion of remote ref with the usual
"push <remote> :<branch>" syntax.
* "git-rebase --abort" did not go back to the right location if
"git-reset" was run during the "git-rebase" session.
* "git imap-send" without setting imap.host did not error out but
segfaulted.
configure script. This not only makes our Makefiles more readable, but
also performs various checks that were previously hard-coded, e.g.
whether or not iconv's *char arguments are constified or not. We also
no longer need the huge mess which checks for the asciidoc/xmlto versions
in git-docs/Makefile. Also, misc. makefile fixes/stylistic changes and
removal of Python dependencies. I don't see how they are needed.
Python modules should be installed as seperate ${PKGPKGPREFIX}-scmgit
packages.
This was a somewhat radical change, so please report any problems.
Changes since 1.5.4:
* RPM spec used to pull in everything with 'git'. This has been
changed so that 'git' package contains just the core parts,
and we now supply 'git-all' metapackage to slurp in everything.
This should match end user's expectation better.
* When some refs failed to update, git-push reported "failure"
which was unclear if some other refs were updated or all of
them failed atomically (the answer is the former). Reworded
the message to clarify this.
* "git clone" from a repository whose HEAD was misconfigured
did not set up the remote properly. Now it tries to do
better.
* Updated git-push documentation to clarify what "matching"
means, in order to reduce user confusion.
* Updated git-add documentation to clarify "add -u" operates in
the current subdirectory you are in, just like other commands.
* git-gui updates to work on OSX and Windows better.
* The configuration parser was not prepared to see string
valued variables misspelled as boolean and segfaulted.
* Temporary files left behind due to interrupted object
transfers were not cleaned up with "git prune".
* "git config --unset" was confused when the unset variables
were spelled with continuation lines in the config file.
* The merge message detection in "git cvsimport" did not catch
a message that began with "Merge...".
* "git status" suggests "git rm --cached" for unstaging the
earlier "git add" before the initial commit.
* "git status" output was incorrect during a partial commit.
* "git bisect" refused to start when the HEAD was detached.
* "git bisect" allowed a wildcard character in the commit
message expanded while writing its log file.
* Manual pages were not formatted correctly with docbook xsl
1.72; added a workaround.
* "git-commit -C $tag" used to work but rewrite in C done in
1.5.4 broke it. This was fixed in 1.5.4.1.
* An entry in the .gitattributes file that names a pattern in a
subdirectory of the directory it is in did not match
correctly (e.g. pattern "b/*.c" in "a/.gitattributes" should
match "a/b/foo.c" but it didn't). This was fixed in 1.5.4.1.
* Customized color specification was parsed incorrectly when
numeric color values are used. This was fixed in 1.5.4.1.
* http transport misbehaved when linked with curl-gnutls.
* "git-commit -C $tag" used to work but rewrite in C done in
1.5.4 broke it.
* An entry in the .gitattributes file that names a pattern in a
subdirectory of the directory it is in did not match
correctly (e.g. pattern "b/*.c" in "a/.gitattributes" should
match "a/b/foo.c" but it didn't).
* Customized color specification was parsed incorrectly when
numeric color values are used. This was fixed in 1.5.4.1.
There are quite a few changes and (welcomed) fixes: please see
the release notes in ${WRKSRC}/Documentation/RelNotes-1.5.4.
A small subset of the changes are included here.
Added
-----
* i18n support for gitk.
Removal
-------
* "git svnimport" was removed in favor of "git svn". It is still there
in the source tree (contrib/examples) but unsupported.
* As git-commit and git-status have been rewritten, "git runstatus"
helper script lost all its users and has been removed.
Fixes since v1.5.3 (unique to the 1.5.4 branch)
------------------
These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
series.
* The way "git diff --check" behaves is much more consistent with the way
"git apply --whitespace=warn" works.
* "git svn" talking with the SVN over HTTP will correctly quote branch
and project names.
* "git config" did not work correctly on platforms that define
REG_NOMATCH to an even number.
* Recent versions of AsciiDoc 8 has a change to break our
documentation; a workaround has been implemented.
* "git diff --color-words" colored context lines in a wrong color.
Also, update to 1.5.3.7.
Fixes since v1.5.3.6
--------------------
* git-send-email added 8-bit contents to the payload without
marking it as 8-bit in a CTE header.
* "git-bundle create a.bndl HEAD" dereferenced the symref and
did not record the ref as 'HEAD'; this prevented a bundle
from being used as a normal source of git-clone.
* The code to reject nonsense command line of the form
"git-commit -a paths..." and "git-commit --interactive
paths..." were broken.
* Adding a signature that is not ASCII-only to an original
commit that is ASCII-only would make the result non-ASCII.
"git-format-patch -s" did not mark such a message correctly
with MIME encoding header.
* git-add sometimes did not mark the resulting index entry
stat-clean. This affected only cases when adding the
contents with the same length as the previously staged
contents, and the previous staging made the index entry
"racily clean".
* git-commit did not honor GIT_INDEX_FILE the user had in the
environment.
* When checking out a revision, git-checkout did not report where the
updated HEAD is if you happened to have a file called HEAD in the
work tree.
* "git-rev-list --objects" mishandled a tree that points at a
submodule.
* "git cvsimport" was not ready for packed refs that "git gc" can
produce and gave incorrect results.
* Many scripted Porcelains were confused when you happened to have a
file called "HEAD" in your work tree.
* Miscellaneous updates to the user manual and documentation.
