These were originally removed by 0232852 (t5537: move
http tests out to t5539, 2014-02-13). However, they were
accidentally re-added in 1ddb4d7 (Merge branch
'nd/upload-pack-shallow', 2014-03-21).
This looks like an error in manual conflict resolution.
Here's what happened:
1. v1.9.0 shipped with the http tests in t5537.
2. We realized that this caused problems, and built
0232852 on top to move the tests to their own file.
This fix made it into v1.9.1.
3. We later had another fix in nd/upload-pack-shallow that
also touched t5537. It was built directly on v1.9.0.
When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

The author of the original topic says he broke the upcoming 2.0
release with something that relates to "synchronization crash

unfortunately be the safest option for the upcoming release.

* rh/prompt-pcmode-avoid-eval-on-refname:
git-prompt.sh: don't assume the shell expands the value of PS1
|
|
Not all shells subject the prompt string to parameter expansion. Test
whether the shell will expand the value of PS1, and use the result to
control whether raw ref names are included directly in PS1.
This fixes a regression introduced in commit 8976500 ("git-prompt.sh:
don't put unsanitized branch names in $PS1"): zsh does not expand PS1
by default, but that commit assumed it did. The bug resulted in
prompts containing the literal string '${__git_ps1_branch_name}'
instead of the actual branch name.

* lt/request-pull:
request-pull: resurrect for-linus -> tags/for-linus DWIM
|
|
Older versions of Git before v1.7.10 did not DWIM
$ git pull $URL for-linus
to the tag "tags/for-linus" and the users were required to say
$ git pull $URL tags/for-linus
instead. Because newer versions of Git works either way,
request-pull used to show tags/for-linus when asked
$ git request-pull origin/master $URL for-linus
The recent updates broke this and in the output we see "for-linus"
without the "tags/" prefix.
As v1.7.10 is more than 2 years old, this should matter very little
in practice, but resurrecting it is very simple.

In large repos, the recursion implementation of contains(commit,
commit_list) may result in a stack overflow. Replace the recursion with
a loop to fix it.
This problem is more apparent on Windows than on Linux, where the stack
is more limited by default.

Both bash and zsh subject the value of PS1 to parameter expansion,
command substitution, and arithmetic expansion. Rather than include
the raw, unescaped branch name in PS1 when running in two- or
three-argument mode, construct PS1 to reference a variable that holds
the branch name. Because the shells do not recursively expand, this
avoids arbitrary code execution by specially-crafted branch names such
as '$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)'.

When the external diff reports an error, we try to clean up
and die. However, we can make this process a bit simpler:
1. We do not need to bother freeing memory, since we are
about to exit. Nor do we need to clean up our
tempfiles, since the atexit() handler will do it for
us. So we can die as soon as we see the error.
3. We can just call die() rather than fprintf/exit. This
does technically change our exit code, but the exit
code of "1" is not meaningful here. In fact, it is
probably wrong, since "1" from diff usually means
"completed successfully, but there were differences".
And while we're there, we can mark the error message for
translation, and drop the full stop at the end to make it
more like our other messages.

git-svn by default puts its Subversion-tracking refs directly in
refs/remotes/*. This runs counter to Git's convention of using
refs/remotes/$remote/* for storing remote-tracking branches.
Furthermore, combining git-svn with regular git remotes run the risk of
clobbering refs under refs/remotes (e.g. if you have a git remote
called "tags" with a "v1" branch, it will overlap with the git-svn's
tracking branch for the "v1" tag from Subversion.
Even though the git-svn refs stored in refs/remotes/* are not "proper"
remote-tracking branches (since they are not covered by a proper git
remote's refspec), they clearly represent a similar concept, and would
benefit from following the same convention.
For example, if git-svn tracks Subversion branch "foo" at
refs/remotes/foo, and you create a local branch refs/heads/foo to add
some commits to be pushed back to Subversion (using "git svn dcommit),
then it is clearly unhelpful of Git to throw
warning: refname 'foo' is ambiguous.
every time you checkout, rebase, or otherwise interact with the branch.
The existing workaround for this is to supply the --prefix=quux/ to
git svn init/clone, so that git-svn's tracking branches end up in
refs/remotes/quux/* instead of refs/remotes/*. However, encouraging
users to specify --prefix to work around a design flaw in git-svn is
suboptimal, and not a long term solution to the problem. Instead,
git-svn should default to use a non-empty prefix that saves
unsuspecting users from the inconveniences described above.
This patch will only affect newly created git-svn setups, as the
--prefix option only applies to git svn init (and git svn clone).
Existing git-svn setups will continue with their existing (lack of)
prefix. Also, if anyone somehow prefers git-svn's old layout, they
can recreate that by explicitly passing an empty prefix (--prefix "")
on the git svn init/clone command line.
The patch changes the default value for --prefix from "" to "origin/",
updates the git-svn manual page, and fixes the fallout in the git-svn
testcases.
(Note that this patch might be easier to review using the --word-diff
and --word-diff-regex=. diff options.)

When a remote helper crashes while pushing we should revert back to the
state before the push, however, it's possible that `git fast-export`
already finished its job, and therefore has exported the marks already.
This creates a synchronization problem because from that moment on
`git fast-{import,export}` will have marks that the remote helper is not
aware of and all further commands fail (if those marks are referenced).
The fix is to tell `git fast-export` to export to a temporary file, and
only after the remote helper has finishes successfully, move to the
final destination.

Since fd0a8c2e (first appearing in v1.7.0), the
t/t5560-http-backend-noserver.sh test has used a backslash escape
inside a ${} expansion in order to specify a literal '?' character.
Unfortunately the FreeBSD /bin/sh does not interpret this correctly.
In a POSIX compliant shell, the following:
x='one?two?three'
echo "${x#*\?}"
Would be expected to produce this:
two?three
When using the FreeBSD /bin/sh instead you get this:
one?two?three
In fact the FreeBSD /bin/sh treats the backslash as a literal
character to match so that this:
y='one\two\three'
echo "${y#*\?}"
Produces this unexpected value:
wo\three
In this case the backslash is not only treated literally, it also
fails to defeat the special meaning of the '?' character.
Instead, we can use the [...] construct to defeat the special meaning
of the '?' character and match it exactly in a way that works for the
FreeBSD /bin/sh as well as other POSIX /bin/sh implementations.
Changing the example like so:
x='one?two?three'
echo "${x#*[?]}"
Produces the expected output using the FreeBSD /bin/sh.
Therefore, change the use of \? to [?] in order to be compatible with
the FreeBSD /bin/sh which allows t/t5560-http-backend-noserver.sh to
pass on FreeBSD again.

Since 11502468 and 04c1ee57 (both first appearing in v1.8.5), the
t7001-mv test has used "cp -a" to perform a copy in several of the
tests.
However, the "-a" option is not required for a POSIX cp utility and
some platforms' cp utilities do not support it.
The POSIX equivalent of -a is -R -P -p.
Change "cp -a" to "cp -R -P -p" so that the t7001-mv test works
on systems with a cp utility that only implements the POSIX
required set of options and not the "-a" option.

This case wants to test passing a bad refname to the "update" command.
But it also passes too few arguments to "update", which muddles the
situation: which error should be diagnosed? So split this test into
two:
* One that passes too few arguments to update
* One that passes all three arguments to "update", but with a bad
refname.

In the original version of this command, for the single case of the
"update" command's <newvalue>, the empty string was interpreted as
being equivalent to 40 "0"s. This shorthand is unnecessary (binary
input will usually be generated programmatically anyway), and it
complicates the parser and the documentation.
So gently deprecate this usage: remove its description from the
documentation and emit a warning if it is found. But for reasons of
backwards compatibility, continue to accept it.

Replace three functions, update_store_new_sha1(),
update_store_old_sha1(), and parse_next_arg(), with a single function,
parse_next_sha1(). The new function takes care of a whole argument,
including checking whether it is there, converting it to an SHA-1, and
emitting errors on EOF or for invalid values. The return value
indicates whether the argument was present or absent, which requires
a bit of intelligence because absent values are represented
differently depending on whether "-z" was used.
The new interface means that the calling functions, parse_cmd_*(),
don't have to interpret the result differently based on the
line_termination mode that is in effect. It also means that
parse_cmd_create() can distinguish unambiguously between an empty new
value and a zeros new value, which fixes a failure in t1400.

The old parse_arg(), when fed an argument
"refs/heads/a"master
parsed 'refs/heads/a' off of the front of the argument and considered
itself successful. It was only when parse_next_arg() tried to parse
the *next* argument that a problem was noticed. But in fact, the
definition of the input format requires arguments to be terminated by
SP or NUL, so *this* argument is already erroneous and parse_arg()
should diagnose the problem.
So teach parse_arg() to verify that C-quoted arguments are terminated
correctly. If not, emit a more specific error message.
There is no corresponding error case of a non-C-quoted argument that
is not terminated correctly, because the end of a non-quoted argument
is *by definition* a space or NUL, so there is no way to insert other
junk between the "end" of the argument and the argument terminator.
Adjust the tests to expect the new error message. Add a docstring to
the function, incorporating the comments that were formerly within the
function plus some added information.

to "git update-ref -z --stdin" to test whether the old-value check for

The test
stdin -z create ref fails with zero new value
actually passes an empty new value, not a zero new value. So rename
the test s/zero/empty/, and change the expected error from
fatal: create $c given zero new value
to
fatal: create $c missing <newvalue>
Of course, this makes the test fail now, because although "git
update-ref" tries to distinguish between these two errors, it does not
succeed in this situation. Fixing it is more than a one-liner, so
mark the test test_expect_failure for now. The failure will be fixed
later in this patch series.
