Ports
* Building on older MacOS X systems automatically sets
the necessary NO_APPLE_COMMON_CRYPTO build-time option.
* Building with NO_PTHREADS has been resurrected.
* Compilation options have been updated a bit to better support the
z/OS port.
UI, Workflows & Features
* "git archive" learned to filter what gets archived with a pathspec.
* "git config --edit --global" starts from a skeletal per-user
configuration file contents, instead of a total blank, when the
user does not already have any global config. This immediately
reduces the need to later ask "Have you forgotten to set
core.user?", and we can add more to the template as we gain
more experience.
* "git stash list -p" used to be almost always a no-op because each
stash entry is represented as a merge commit. It learned to show
the difference between the base commit version and the working tree
version, which is in line with what "git stash show" gives.
* Sometimes users want to report a bug they experience on their
repository, but they are not at liberty to share the contents of
the repository. "fast-export" was taught an "--anonymize" option
to replace blob contents, names of people, paths and log
messages with bland and simple strings to help them.
* "git difftool" learned an option to stop feeding paths to the
diff backend when it exits with a non-zero status.
* "git grep" learned to paint (or not paint) partial matches on
context lines when showing "grep -C<num>" output in color.
* "log --date=iso" uses a slight variant of the ISO 8601 format that is
more human readable. A new "--date=iso-strict" option gives
datetime output that conforms more strictly.
* The logic "git prune" uses is more resilient against various corner
cases.
* A broken reimplementation of Git could write an invalid index that
records both stage 0 and higher-stage entries for the same path.
We now notice and reject such an index, as there is no sensible
fallback (we do not know if the broken tool wanted to resolve and
forgot to remove the higher-stage entries, or if it wanted to unresolve
and forgot to remove the stage 0 entry).
* The temporary files "git mergetool" uses are renamed to avoid too
many dots in them (e.g. a temporary file for "hello.c" used to be
named e.g. "hello.BASE.4321.c" but now uses underscore instead,
e.g. "hello_BASE_4321.c", to allow us to have multiple variants).
* The temporary files "git mergetool" uses can be placed in a newly
created temporary directory, instead of the current directory, by
setting the mergetool.writeToTemp configuration variable.
* "git mergetool" understands "--tool bc" now, as version 4 of
BeyondCompare can be driven the same way as its version 3 and it
feels awkward to say "--tool bc3" to run version 4.
* The "pre-receive" and "post-receive" hooks are no longer required
to consume their input fully (not following this requirement used
to result in intermittent errors in "git push").
* The pretty-format specifier "%d", which expands to " (tagname)"
for a tagged commit, gained a cousin "%D" that just gives the
"tagname" without frills.
* "git push" learned "--signed" push, that allows a push (i.e.
request to update the refs on the other side to point at a new
history, together with the transmission of necessary objects) to be
signed, so that it can be verified and audited, using the GPG
signature of the person who pushed, that the tips of branches at a
public repository really point the commits the pusher wanted to,
without having to "trust" the server.
* "git interpret-trailers" is a new filter to programmatically edit
the tail end of the commit log messages, e.g. "Signed-off-by:".
* "git help everyday" shows the "Everyday Git in 20 commands or so"
document, whose contents have been updated to match more modern
Git practice.
* On the "git svn" front, work progresses to reduce memory consumption and
to improve handling of mergeinfo.
Backward compatibility notes
----------------------------
* The default value we give to the environment variable LESS has been
changed from "FRSX" to "FRX", losing "S" (chop long lines instead
of wrapping). Existing users who prefer not to see line-wrapped
output may want to set
$ git config core.pager "less -S"
to restore the traditional behaviour. It is expected that people
find output from most subcommands easier to read with the new
default, except for "blame" which tends to produce really long
lines. To override the new default only for "git blame", you can
do this:
$ git config pager.blame "less -S"
* A few disused directories in contrib/ have been retired.
Updates since v2.0
------------------
UI, Workflows & Features
* Since the very beginning of Git, we gave the LESS environment a
default value "FRSX" when we spawn "less" as the pager. "S" (chop
long lines instead of wrapping) has been removed from this default
set of options, because it is more or less a personal taste thing,
as opposed to the others that have good justifications (i.e. "R" is
very much justified because many kinds of output we produce are
colored and "FX" is justified because output we produce is often
shorter than a page).
* The logic and data used to compute the display width needed for
UTF-8 strings have been updated to match Unicode 7.0 better.
* HTTP-based transports learned to better propagate the error messages from
the webserver to the client coming over the HTTP transport.
* The completion script for bash (in contrib/) has been updated to
better handle aliases that define a complex sequence of commands.
* The "core.preloadindex" configuration variable is enabled by default,
allowing modern platforms to take advantage of their
multiple cores.
* "git clone" applies the "if cloning from a local disk, physically
copy the repository using hardlinks, unless otherwise told not to with
--no-local" optimization when the url.*.insteadOf mechanism rewrites a
remote-repository "git clone $URL" into a
clone from a local disk.
* "git commit --date=<date>" option learned more
timestamp formats, including "--date=now".
* The `core.commentChar` configuration variable is used to specify a
custom comment character (other than the default "#") for
the commit message editor. This can be set to `auto` to attempt to
choose a different character that does not conflict with any that
already starts a line in the message being edited, for cases like
"git commit --amend".
* "git format-patch" learned --signature-file=<file> to add the contents
of a file as a signature to the mail message it produces.
* "git grep" learned the grep.fullname configuration variable to force
"--full-name" to be the default. This may cause regressions for
scripted users who do not expect this new behaviour.
* "git imap-send" learned to ask the credential helper for auth
material.
* "git log" and friends now understand the value "auto" for the
"log.decorate" configuration variable to enable the "--decorate"
option automatically when the output is sent to tty.
* "git merge" without an argument, even when there is an upstream
defined for the current branch, refused to run until
merge.defaultToUpstream is set to true. Flip the default of that
configuration variable to true.
* "git mergetool" learned to drive the vimdiff3 backend.
* mergetool.prompt used to default to 'true', always asking "do you
really want to run the tool on this path?". The default has been
changed to 'false'. However, the prompt will still appear if
mergetool used its autodetection system to guess which tool to use.
Users who explicitly specify or configure a tool will no longer see
the prompt by default.
Strictly speaking, this is a backward incompatible change and
users need to explicitly set the variable to 'true' if they want
to be prompted to confirm running the tool on each path.
* "git replace" learned the "--edit" subcommand to create a
replacement by editing an existing object.
* "git replace" learned a "--graft" option to rewrite the parents of a
commit.
* "git send-email" learned "--to-cover" and "--cc-cover" options, to
tell it to copy To: and Cc: headers found in the first input file
when emitting later input files.
* "git svn" learned to cope with malformed timestamps with only one
digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted
by some broken subversion server implementations.
* "git tag" when editing the tag message shows the name of the tag
being edited as a comment in the editor.
* "git tag" learned to pay attention to "tag.sort" configuration, to
be used as the default sort order when no --sort=<value> option
is given.
* A new "git verify-commit" command, to check GPG signatures in signed
commits, in a way similar to "git verify-tag" is used to check
signed tags, was added.
has been linking with Apple's CommonCrypto instead. Add an
"apple-common-crypto" option that explicitly avoids CommonCrypto
when it's off. Turn it off by default, and set PKG_FAIL_REASON if
it's enabled on an unsuitable system.
While here, regenerate fuzzy patches.
Addresses pkg/49051. Bump PKGREVISION.
Foreign interfaces, subsystems and ports.
* The HTTP transport, when talking GSS-Negotiate, uses "100
Continue" response to avoid having to rewind and resend a large
payload, which may not be always doable.
* Various bugfixes to remote-bzr and remote-hg (in contrib/).
* The build procedure is aware of MirBSD now.
* Various "git p4", "git svn" and "gitk" updates.
UI, Workflows & Features
* Fetching from a shallowly-cloned repository used to be forbidden,
primarily because the codepaths involved were not carefully vetted
and we did not bother supporting such usage. This release attempts
to allow object transfer out of a shallowly-cloned repository in a
more controlled way (i.e. the receiver becomes a shallow repository
with a truncated history).
* Just like we give a reasonable default for "less" via the LESS
environment variable, we now specify a reasonable default for "lv"
via the "LV" environment variable when spawning the pager.
* Two-level configuration variable names in "branch.*" and "remote.*"
hierarchies, whose variables are predominantly three-level, were
not completed by hitting a <TAB> in bash and zsh completions.
* Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol'
remote-tracking branch from an earlier fetch was still there, would
error out, primarily because the command was not told that it is
allowed to lose any information on our side. "git fetch --prune"
now can be used to remove 'frotz/nitfol' to make room for fetching and
storing the 'frotz' remote-tracking branch.
* "diff.orderfile=<file>" configuration variable can be used to
pretend as if the "-O<file>" option were given from the command
line of "git diff", etc.
* The negative pathspec syntax allows "git log -- . ':!dir'" to tell
us "I am interested in everything but 'dir' directory".
* "git difftool" shows how many different paths there are in total,
and how many of them have been shown so far, to indicate progress.
* "git push origin master" used to push our 'master' branch to update
the 'master' branch at the 'origin' repository. This has been
enhanced to use the same ref mapping "git push origin" would use to
determine what ref at the 'origin' to be updated with our 'master'.
For example, with this configuration
[remote "origin"]
push = refs/heads/*:refs/review/*
that would cause "git push origin" to push out our local branches
to corresponding refs under refs/review/ hierarchy at 'origin',
"git push origin master" would update 'refs/review/master' over
there. Alternatively, if push.default is set to 'upstream' and our
'master' is set to integrate with 'topic' from the 'origin' branch,
running "git push origin" while on our 'master' would update their
'topic' branch, and running "git push origin master" while on any
of our branches does the same.
* "gitweb" learned to treat ref hierarchies other than refs/heads as
if they are additional branch namespaces (e.g. refs/changes/ in
Gerrit).
* "git for-each-ref --format=..." learned a few formatting directives;
e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)".
* The command string given to "git submodule foreach" is passed
directly to the shell, without being eval'ed. This is a backward
incompatible change that may break existing users.
* "git log" and friends learned the "--exclude=<glob>" option, to
allow people to say "list history of all branches except those that
match this pattern" with "git log --exclude='*/*' --branches".
* "git rev-parse --parseopt" learned a new "--stuck-long" option to
help scripts parse options with an optional parameter.
* The "--tags" option to "git fetch" no longer tells the command to
fetch _only_ the tags. It instead fetches tags _in addition to_
what are fetched by the same command line without the option.
* "git fetch --depth=0" was a no-op, and was silently ignored.
Diagnose it as an error.
* Remote repository URL expressed in scp-style host:path notation are
parsed more carefully (e.g. "foo/bar:baz" is local, "[::1]:/~user" asks
to connect to user's home directory on host at address ::1.
* SSL-related options were not passed correctly to underlying socket
layer in "git send-email".
* "git commit -v" appends the patch to the log message before
editing, and then removes the patch when the editor returned
control. However, the patch was not stripped correctly when the
first modified path was a submodule.
* "git mv A B/", when B does not exist as a directory, should error
out, but it didn't.
* When we figure out how many file descriptors to allocate for
keeping packfiles open, a system with non-working getrlimit() could
cause us to die(), but because we make this call only to get a
rough estimate of how many is available and we do not even attempt
to use up all file descriptors available ourselves, it is nicer to
fall back to a reasonable low value rather than dying.
* "git log --decorate" did not handle a tag pointed by another tag
nicely.
* "git add -A" (no other arguments) in a totally empty working tree
used to emit an error.
* There is no reason to have a hardcoded upper limit of the number of
parents for an octopus merge, created via the graft mechanism, but
there was.
* The implementation of 'git stash $cmd "stash@{...}"' did not quote
the stash argument properly and left it split at IFS whitespace.
* The documentation to "git pull" hinted there is an "-m" option
because it incorrectly shared the documentation with "git merge".
Also contains typofixes, documentation updates and trivial code clean-ups.
git-svn: workaround for a bug in svn serf backend
Subversion serf backend in versions 1.8.5 and below has a bug that the
function creating the descriptor of a file change -- add_file() --
doesn't make a copy of its 3d argument when storing it on the returned
descriptor. As a result, by the time this field is used (in
transactions of file copying or renaming) it may well be released.
This patch works around this bug, by storing the value to be passed as
the 3d argument to add_file() in a local variable with the same scope as
the file change descriptor, making sure their lifetime is the same.

* "git submodule init" copied "submodule.$name.update" settings from
.gitmodules to .git/config without making sure if the suggested
value was sensible.
* Some old versions of bash do not grok some constructs like
'printf -v varname' which the prompt and completion code started
to use recently. The completion and prompt scripts have been
adjusted to work better with these old versions of bash.
* In FreeBSD's and NetBSD's "sh", a return in a dot script in a
function returns from the function, not only in the dot script,
breaking "git rebase" on these platforms (regression introduced
in 1.8.4-rc1).
* "git rebase -i" and other scripted commands were feeding a
random, data dependant error message to 'echo' and expecting it
to come out literally.
* Setting the "submodule.<name>.path" variable to the empty
"true" caused the configuration parser to segfault.
* Output from "git log --full-diff -- <pathspec>" looked strange
because comparison was done with the previous ancestor that
touched the specified <pathspec>, causing the patches for paths
outside the pathspec to show more than the single commit has
changed.
* The auto-tag-following code in "git fetch" tries to reuse the
same transport twice when the serving end does not cooperate and
does not give tags that point to commits that are asked for as
part of the primary transfer. Unfortunately, Git-aware transport
helper interface is not designed to be used more than once, hence
this did not work over smart-http transfer. Fixed.
* Send a large request to read(2)/write(2) as a smaller but still
reasonably large chunks, which would improve the latency when the
operation needs to be killed and incidentally works around broken
64-bit systems that cannot take a 2GB write or read in one go.
* A ".mailmap" file that ends with an incomplete line, when read
from a blob, was not handled properly.
* The recent "short-cut clone connectivity check" topic broke a
shallow repository when a fetch operation tries to auto-follow
tags.
* 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.
* A call to xread() was used without a loop to cope with short
read in the codepath to stream large blobs to a pack.
* On platforms with fgetc() and friends defined as macros, the
configuration parser did not compile.
* New versions of MediaWiki introduced a new API for returning
more than 500 results in response to a query, which would cause
the MediaWiki remote helper to go into an infinite loop.
* Subversion's serf access method (the only one available in
Subversion 1.8) for http and https URLs in skelta mode tells its
caller to open multiple files at a time, which made "git svn
fetch" complain that "Temp file with moniker 'svn_delta' already
in use" instead of fetching.
Also contains a handful of trivial code clean-ups, documentation
updates, updates to the test suite, etc.
Git is a free and open source distributed version control system
designed to handle everything from small to very large projects with
speed and efficiency.
Git is easy to learn and has a tiny footprint with lightning fast
performance. It outclasses SCM tools like Subversion, CVS, Perforce,
and ClearCase with features like cheap local branching, convenient
staging areas, and multiple workflows.
This package contains only the git program (and subcommands). It does
not contain man pages or the tk-based repository browser.
