Commit 4796e823 ("bisect: introduce --no-checkout support into porcelain." Aug 4 2011)
made checking out the branch where we started depends on the "checkout" mode. But
unfortunately it lost the "|| exit" part after the checkout command.
As it makes no sense to continue if the checkout failed and as people have already
complained that the error message given when we just exit in this case is not clear, see:
http://thread.gmane.org/gmane.comp.version-control.git/180733/
this patch adds a "|| die <hopefully clear message>" part after the checkout command.

The threading tests turn on format.thread, but never clean
up after themselves, meaning that later tests will also have
format.thread set.
This is more annoying than most leftover config, too,
because not only does it impact the results of other tests,
but it does so non-deterministically. Threading requires the
generation of message-ids, which incorporate the current
time, meaning a slow-running test script may generate
different results from run to run.

With the usual "git" transport, a large-ish transfer with "git fetch" and
"git pull" give progress eye-candy to avoid boring users. However, not
when they are reading from a bundle. I.e.
$ git pull ../git-bundle.bndl master
This teaches bundle.c:unbundle() to give "-v" option to index-pack and
tell it to give progress bar when transport decides it is necessary.
The operation in the other direction, "git bundle create", could also
learn to honor --quiet but that is a separate issue.

HEAD and MERGE_HEAD (among other branch tips) should never hold a
tag. That can only be caused by broken tools and is cumbersome to fix
by an end user with:
$ git update-ref HEAD $(git rev-parse HEAD^{commit})
which may look like a magic to a new person.
Be easy, warn users (so broken tools can be fixed if they bother to
report) and move on.
Be robust, if the given SHA-1 cannot be resolved to a commit object,
die (therefore return value is always valid).

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.
Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

What should happen if you run this command?
$ git ls-remote -h
It does not give a short-help for the command. Instead because "-h" is a
synonym for "--heads", it runs "git ls-remote --heads", and because there
is no remote specified on the command line, we run it against the default
"origin" remote, hence end up doing the same as
$ git ls-remote --heads origin
Fix this counter-intuitive behaviour by special casing a lone "-h" that
does not have anything else on the command line and calling usage().

The current code, as is, passes control characters, such as form-feed
(^L) to highlight which then passes it through to the browser. User
agents (web browsers) that support 'application/xhtml+xml' usually
require that web pages declared as XHTML and with this mimetype are
well-formed XML. Unescaped control characters cannot appear within a
contents of a valid XML document.
This will cause the browser to display one of the following warnings:
* Safari v5.1 (6534.50) & Google Chrome v13.0.782.112:
This page contains the following errors:
error on line 657 at column 38: PCDATA invalid Char value 12
Below is a rendering of the page up to the first error.
* Mozilla Firefox 3.6.19 & Mozilla Firefox 5.0:
XML Parsing Error: not well-formed
Location:
http://path/to/git/repo/blah/blah
Both errors were generated by gitweb.perl v1.7.3.4 w/ highlight 2.7
using arch/ia64/kernel/unwind.c from the Linux kernel.
When syntax highlighter is not used, control characters are replaced
by esc_html(), but with syntax highlighter they were passed through to
browser (to_utf8() doesn't remove control characters).
Introduce sanitize() subroutine which strips forbidden characters, but
does not perform HTML escaping, and use it in git_blob() to sanitize
syntax highlighter output for XHTML.
Note that excluding "\t" (U+0009), "\n" (U+000A) and "\r" (U+000D) is
not strictly necessary, atleast for currently the only callsite: "\t"
tabs are replaced by spaces by untabify(), "\n" is stripped from each
line before processing it, and replacing "\r" could be considered
improvement.

The submodule code recently grew generic code to build a
dynamic argv array. Many other parts of the code can reuse
this, too, so let's make it generically available.
There are two enhancements not found in the original code:
1. We now handle the NULL-termination invariant properly,
even when no strings have been pushed (before, you
could have an empty, NULL argv). This was not a problem
for the submodule code, which always pushed at least
one argument, but was not sufficiently safe for
generic code.
2. There is a formatted variant of the "push" function.
This is a convenience function which was not needed by
the submodule code, but will make it easier to port
other users to the new code.

As a bonus, this also fixes a few buggy tests that used

Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.
In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.
In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.
This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.

Recent versions of git can be slow to fetch repositories with a
large number of refs (or when they already have a large
number of refs). For example, GitHub makes pull-requests
available as refs, which can lead to a large number of
available refs. This slowness goes away when submodule
recursion is turned off:
$ git ls-remote git://github.com/rails/rails.git | wc -l
3034
[this takes ~10 seconds of CPU time to complete]
git fetch --recurse-submodules=no \
git://github.com/rails/rails.git "refs/*:refs/*"
[this still isn't done after 10 _minutes_ of pegging the CPU]
git fetch \
git://github.com/rails/rails.git "refs/*:refs/*"
You can produce a quicker and simpler test case like this:
doit() {
head=`git rev-parse HEAD`
for i in `seq 1 $1`; do
echo $head refs/heads/ref$i
done >.git/packed-refs
echo "==> $1"
rm -rf dest
git init -q --bare dest &&
(cd dest && time git.compile fetch -q .. refs/*:refs/*)
}
rm -rf repo
git init -q repo && cd repo &&
>file && git add file && git commit -q -m one
doit 100
doit 200
doit 400
doit 800
doit 1600
doit 3200
Which yields timings like:
# refs seconds of CPU
100 0.06
200 0.24
400 0.95
800 3.39
1600 13.66
3200 54.09
Notice that although the number of refs doubles in each
trial, the CPU time spent quadruples.
The problem is that the submodule recursion code works
something like:
- for each ref we fetch
- for each commit in git rev-list $new_sha1 --not --all
- add modified submodules to list
- fetch any newly referenced submodules
But that means if we fetch N refs, we start N revision
walks. Worse, because we use "--all", the number of refs we
must process that constitute "--all" keeps growing, too. And
you end up doing O(N^2) ref resolutions.
Instead, this patch structures the code like this:
- for each sha1 we already have
- add $old_sha1 to list $old
- for each ref we fetch
- add $new_sha1 to list $new
- for each commit in git rev-list $new --not $old
- add modified submodules to list
- fetch any newly referenced submodules
This yields timings like:
# refs seconds of CPU
100 0.00
200 0.04
400 0.04
800 0.10
1600 0.21
3200 0.39
Note that the amount of effort doubles as the number of refs
doubles. Similarly, the fetch of rails.git takes about as
much time as it does with --recurse-submodules=no.
