A request to fetch from a client over smart HTTP protocol is served in
multiple steps. In the first round, the server side shows the set of refs
it has and their values, and the client picks from them and sends "I want
to fetch the history leading to these commits".
When the server tries to respond to this second request, its refs may have
progressed by a push from elsewhere. By design, we do not allow fetching
objects that are not at the tip of an advertised ref, and the server
rejects such a request. The client needs to try again, which is not ideal
especially for a busy server.
Teach upload-pack (which is the workhorse driven by git-daemon and smart
http server interface) that it is OK for a smart-http client to ask for
commits that are not at the tip of any advertised ref, as long as they are
reachable from advertised refs.

According to `git help filter-branch':
--commit-filter <command>
...
You can use the _map_ convenience function in this filter,
and other convenience functions, too...
...
However, it turns out that `map' hasn't been usable because it depends
on the variable `workdir', which is not propogated to the environment
of the shell that runs the commit-filter <command> because the
shell is created via a simple-command rather than a compound-command
subshell:
@SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
$(git write-tree) $parentstr < ../message > ../map/$commit ||
die "could not write rewritten commit"
One solution is simply to export `workdir'. However, it seems rather
heavy-handed to export `workdir' to the environments of all commands,
so instead this commit exports `workdir' for only the duration of the
shell command in question:
workdir=$workdir @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
$(git write-tree) $parentstr < ../message > ../map/$commit ||
die "could not write rewritten commit"

Many pathnames in a fast-import stream need to be quoted. In
particular:
1. Pathnames at the end of an "M" or "D" line need quoting
if they contain a LF or start with double-quote.
2. Pathnames on a "C" or "R" line need quoting as above,
but also if they contain spaces.
For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.
This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.
In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

The combined diff machinery can be used to compare:
- a merge commit with its parent commits;
- a working-tree file with multiple stages in an unmerged index; or
- a working-tree file with the HEAD and the index.
The internal function combine-diff.c:show_patch_diff() checked if it needs
to read the "result" from the working tree by looking at the object name
of the result --- if it is null_sha1, it read from the working tree.
This mistook a merge that records a deletion as the conflict resolution
as if it is a cue to read from the working tree. Pass this information
explicitly from the caller instead.

If the pager fails to run, git produces no output, e.g.:
$ GIT_PAGER=not-a-command git log
The error reporting fails for two reasons:
(1) start_command: There is a mechanism that detects errors during
execvp introduced in 2b541bf8 (start_command: detect execvp
failures early). The child writes one byte to a pipe only if
execvp fails. The parent waits for either EOF, when the
successful execvp automatically closes the pipe (see
FD_CLOEXEC in fcntl(1)), or it reads a single byte, in which
case it knows that the execvp failed. This mechanism is
incompatible with the workaround introduced in 35ce8622
(pager: Work around window resizing bug in 'less'), which
waits for input from the parent before the exec. Since both
the parent and the child are waiting for input from each
other, that would result in a deadlock. In order to avoid
that, the mechanism is disabled by closing the child_notifier
file descriptor.
(2) finish_command: The parent correctly detects the 127 exit
status from the child, but the error output goes nowhere,
since by that time it is already being redirected to the
child.
No simple solution for (1) comes to mind.
Number (2) can be solved by not sending error output to the pager.
Not redirecting error output to the pager can result in the pager
overwriting error output with standard output, however.
Since there is no reliable way to handle error reporting in the
parent, produce the output in the child instead.

not ok - 41 use superproject as upstream when path is relative and no url is set there
The failing test does:
git submodule add ../repo relative &&
...
git submodule sync relative &&
test "$(git config submodule.relative.url)" = "$submodurl/repo"
where $submodurl comes from the $TRASH_DIRECTORY the user
gave us. However, git will resolve symlinks when converting
the relative path into an absolute one, leading them to be
textually different (even though they point to the same
directory).

On modern multi-core processors "make test" is often run in multiple jobs.
If one of them fails the test run does stop, but the concurrently running
tests finish their run. It is rather easy to find out which test failed by
doing a "ls -d t/trash*". But that only works when you don't use the "-i"
option to "make test" because you want to get an overview of all failing
tests. In that case all thrash directories are deleted end and the
information which tests failed is lost.
If one or more tests failed, print a list of them before the test summary:
failed test(s): t1000 t6500
fixed 0
success 7638
failed 3
broken 49
total 7723
This makes it possible to just run the test suite with -i and collect all
failed test scripts at the end for further examination.

The "notemodify" fast-import command was introduced in commit a8dd2e7
(fast-import: Add support for importing commit notes, 2009-10-09)
The commit log has slightly different description than the added
documentation. The latter is somewhat confusing. "notemodify" is a
subcommand of "commit" command used to add a note for some commit.
Does this note annotate the commit produced by the "commit" command
or a commit given by it's committish parameter? Which notes tree
does it write notes to?
The exact meaning could be deduced with old description and some
notes machinery knowledge. But let's make it more obvious. This
command is used in a context like "commit refs/notes/test" to
add or rewrite an annotation for a committish parameter. So the
advised way to add notes in a fast-import stream is:
1) import some commits (optional)
2) prepare a "commit" to the notes tree:
2.1) choose notes ref, committer, log message, etc.
2.2) create annotations with "notemodify", where each can refer to
a commit being annotated via a branch name, import mark reference,
sha1 and other expressions specified in the Documentation.

The reset command creates its reflog entry from argv.
However, it does so after having run parse_options, which
means the only thing left in argv is any non-option
arguments. Thus you would end up with confusing reflog
entries like:
$ git reset --hard HEAD^
$ git reset --soft HEAD@{1}
$ git log -2 -g --oneline
8e46cad HEAD@{0}: HEAD@{1}: updating HEAD
1eb9486 HEAD@{1}: HEAD^: updating HEAD
However, we must also consider that some scripts may set
GIT_REFLOG_ACTION before calling reset, and we need to show
their reflog action (with our text appended). For example:
rebase -i (squash): updating HEAD
On top of that, we also set the ORIG_HEAD reflog action
(even though it doesn't generally exist). In that case, the
reset argument is somewhat meaningless, as it has nothing to
do with what's in ORIG_HEAD.
This patch changes the reset reflog code to show:
$GIT_REFLOG_ACTION: updating {HEAD,ORIG_HEAD}
as before, but only if GIT_REFLOG_ACTION is set. Otherwise,
show:
reset: moving to $rev
for HEAD, and:
reset: updating ORIG_HEAD
for ORIG_HEAD (this is still somewhat superfluous, since we
are in the ORIG_HEAD reflog, obviously, but at least we now
mention which command was used to update it).
While we're at it, we can clean up the code a bit:
- Use strbufs to make the message.
- Use the "rev" parameter instead of showing all options.
This makes more sense, since it is the only thing
impacting the writing of the ref.

The SYNOPSIS sections of most commands that span several lines already
use [verse] to retain line breaks. Most commands that don't span
several lines seem not to use [verse]. In the HTML output, [verse]
does not only preserve line breaks, but also makes the section
indented, which causes a slight inconsistency between commands that
use [verse] and those that don't. Use [verse] in all SYNOPSIS sections
for consistency.
Also remove the blank lines from git-fetch.txt and git-rebase.txt to
align with the other man pages. In the case of git-rebase.txt, which
already uses [verse], the blank line makes the [verse] not apply to

Enhance usability of 'blob_plain' view protection against XSS attacks
(enabled by setting $prevent_xss to true) by serving contents inline
as safe 'text/plain' mimetype where possible, instead of serving with

gitweb's security domain.
This patch broadens downgrading to 'text/plain' further, to any
*/*+xml mimetype. This includes:
application/xhtml+xml (*.xhtml, *.xht)
application/atom+xml (*.atom)
application/rss+xml (*.rss)
application/mathml+xm (*.mathml)
application/docbook+xml (*.docbook)
image/svg+xml (*.svg, *.svgz)
Probably most useful is serving XHTML files as text/plain in
'blob_plain' view, directly viewable.
Because file with 'image/svg+xml' mimetype can be compressed SVGZ
file, we have to check if */*+xml really is text file, via '-T $fd'.
