Git v1.9-rc0

An early preview release Git v1.9-rc0 is now available for testing
at the usual places. I tagged this late last week, but forgot to
send out the announcement before I left for the weekend, and then I
wasn’t well yesterday, but anyway. There still may be a few minor
topics not in this preview but should be in the final release, but
otherwise, this should be pretty close to “it”.

It has been reported that turning git.rc into git.res does not like
the new 2-dewey-decimal release numbering scheme; packagers of
various distro might find similar issues in their build procedures,
in which case they have about 3 weeks to update them until the final
release.

The release tarballs are found at:

Git v1.9 Release Notes (draft)

Backward compatibility notes

“git submodule foreach $cmd $args” used to treat “$cmd $args” the same
way “ssh” did, concatenating them into a single string and letting the
shell unquote. Careless users who forget to sufficiently quote $args
gets their argument split at $IFS whitespaces by the shell, and got
unexpected results due to this. Starting from this release, the
command line is passed directly to the shell, if it has an argument.

Read-only support for experimental loose-object format, in which users
could optionally choose to write in their loose objects for a short
while between v1.4.3 to v1.5.3 era, has been dropped.

The meanings of “–tags” option to “git fetch” has changed; the
command fetches tags in addition to what are fetched by the same
command line without the option.

The way “git push $there $what” interprets $what part given on the
command line, when it does not have a colon that explicitly tells us
what ref at the $there repository is to be updated, has been enhanced.

A handful of ancient commands that have long been deprecated are
finally gone (repo-config, tar-tree, lost-found, and peek-remote).

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, which 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 v1.8.5

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.

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 become 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 frotz branch with “git fetch”, while 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 to fetch and
    store 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.

Performance, Internal Implementation, etc.

  • When parsing a 40-hex string into the object name, the string is
    checked to see if it can be interpreted as a ref so that a warning
    can be given for ambiguity. The code kicked in even when the
    core.warnambiguousrefs is set to false to squelch this warning, in
    which case the cycles spent to look at the ref namespace were an
    expensive no-op, as the result was discarded without being used.

  • The naming convention of the packfiles has been updated; it used to
    be based on the enumeration of names of the objects that are
    contained in the pack, but now it also depends on how the packed
    result is represented—packing the same set of objects using
    different settings (or delta order) would produce a pack with
    different name.

  • “git diff –no-index” mode used to unnecessarily attempt to read
    the index when there is one.

  • The deprecated parse-options macro OPT_BOOLEAN has been removed;
    use OPT_BOOL or OPT_COUNTUP in new code.

  • A few duplicate implementations of prefix/suffix string comparison
    functions have been unified to starts_with() and ends_with().

  • The new PERLLIB_EXTRA makefile variable can be used to specify
    additional directories Perl modules (e.g. the ones necessary to run
    git-svn) are installed on the platform when building.

  • “git merge-base” learned the “–fork-point” mode, that implements
    the same logic used in “git pull –rebase” to find a suitable fork
    point out of the reflog entries for the remote-tracking branch the
    work has been based on. “git rebase” has the same logic that can be
    triggered with the “–fork-point” option.

  • A third-party “receive-pack” (the responder to “git push”) can
    advertise the “no-thin” capability to tell “git push” not to use
    the thin-pack optimization. Our receive-pack has always been
    capable of accepting and fattening a thin-pack, and will continue
    not to ask “git push” to use a non-thin pack.

Also contains various documentation updates and code clean-ups.

Fixes since v1.8.5

Unless otherwise noted, all the fixes since v1.8.5 in the maintenance
track are contained in this release (see the maintenance releases’ notes
for details).

  • “submodule..update=checkout”, when propagated from .gitmodules to
    .git/config, turned into a “submodule.
    .update=none”, which did not
    make much sense.
    (merge efa8fd7 fp/submodule-checkout-mode later to maint).

  • The implementation of git stash $cmd “stash@{…}” did not quote
    the stash argument properly and left it split at IFS whitespace.
    (merge 2a07e43 ow/stash-with-ifs later to maint).

  • The “–[no-]informative-errors” options to “git daemon” were parsed
    a bit too loosely, allowing any other string after these option
    names.
    (merge 82246b7 nd/daemon-informative-errors-typofix later to maint).

  • 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.
    (merge e228c17 js/lift-parent-count-limit later to maint).

  • The basic test used to leave unnecessary trash directories in the
    t/ directory.
    (merge 738a8be jk/test-framework-updates later to maint).

  • “git merge-base –octopus” used to leave cleaning up suboptimal
    result to the caller, but now it does the clean-up itself.
    (merge 8f29299 bm/merge-base-octopus-dedup later to maint).

  • A “gc” process running as a different user should be able to stop a
    new “gc” process from starting, but it didn’t.
    (merge ed7eda8 km/gc-eperm later to maint).

  • An earlier “clean-up” introduced an unnecessary memory leak.
    (merge e1c1a32 jk/credential-plug-leak later to maint).

  • “git add -A” (no other arguments) in a totally empty working tree
    used to emit an error.
    (merge 64ed07c nd/add-empty-fix later to maint).

  • “git log –decorate” did not handle a tag pointed by another tag
    nicely.
    (merge 5e1361c bc/log-decoration later to maint).

  • 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.
    (merge 491a8de jh/rlimit-nofile-fallback later to maint).

  • read_sha1_file(), that is the workhorse to read the contents given
    an object name, honoured object replacements, but there was no
    corresponding mechanism to sha1_object_info() that was used to
    obtain the metainfo (e.g. type & size) about the object. This led
    callers to weird inconsistencies.
    (merge 663a856 cc/replace-object-info later to maint).

  • “git cat-file –batch=”, an admittedly useless command, did not
    behave very well.
    (merge 6554dfa jk/cat-file-regression-fix later to maint).

  • “git rev-parse <revs> — <paths>” did not implement the usual
    disambiguation rules the commands in the “git log” family used in
    the same way.
    (merge 62f162f jk/rev-parse-double-dashes later to maint).

  • “git mv A B/”, when B does not exist as a directory, should error
    out, but it didn’t.
    (merge c57f628 mm/mv-file-to-no-such-dir-with-slash later to maint).

  • A workaround to an old bug in glibc prior to glibc 2.17 has been
    retired; this would remove a side effect of the workaround that
    corrupts system error messages in non-C locales.

  • SSL-related options were not passed correctly to underlying socket
    layer in “git send-email”.
    (merge 5508f3e tr/send-email-ssl later to maint).

  • “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.
    (merge 1a72cfd jl/commit-v-strip-marker later to maint).

  • “git fetch –depth=0” was a no-op, and was silently ignored.
    Diagnose it as an error.
    (merge 5594bca nd/transport-positive-depth-only later to maint).

  • 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.
    (merge a2036d7 tb/clone-ssh-with-colon-for-port later to maint).

  • “git diff — :(icase)makefile” was unnecessarily rejected at the
    command line parser.
    (merge 887c6c1 nd/magic-pathspec later to maint).

  • “git cat-file –batch-check=ok” did not check the existence of
    the named object.
    (merge 4ef8d1d sb/sha1-loose-object-info-check-existence later to maint).

  • “git am –abort” sometimes complained about not being able to write
    a tree with an 0{40} object in it.
    (merge 77b43ca jk/two-way-merge-corner-case-fix later to maint).

  • Two processes creating loose objects at the same time could have
    failed unnecessarily when the name of their new objects started
    with the same byte value, due to a race condition.
    (merge b2476a6 jh/loose-object-dirs-creation-race later to maint).
