rebase: remove obsolete and unused LONG_USAGE which breaks xgettext

Since there is a modern OPTIONS_SPEC variable in use in this script,
the obsolete USAGE and LONG_USAGE variables are no longer used.
Remove them.

In addition, the obsolete LONG_USAGE variable has the following
message in it:

A'\''--B'\''--C'\''

And such complex LONG_USAGE message will break xgettext when
extracting l10n messages (but if single quotes are removed from the
message, xgettext works fine on 'git-rebase.sh').

i18n: Rewrite gettext messages start with dash

Gettext message in a shell script should not start with '-', one
workaround is adding '--' between gettext and the message, like:

gettext -- "--exec option ..."

But due to a bug in the xgettext extraction, xgettext can not
extract the actual message for this case. Rewriting the message
is a simpler and better solution.

t7502: test early quit from commit with bad ident

In commit f20f387, "git commit" notices and dies much
earlier when we have a bogus commit identity. That commit
did not add a test because we cannot do so reliably (namely,
we can only trigger the behavior on a system where the
automatically generated identity is bogus). However, now
that we have a prerequisite check for this feature, we can
add a test that will at least run on systems that produce
such a bogus identity.

t7502: handle systems where auto-identity is broken

Test t7502.21 checks whether we write the committer name
into COMMIT_EDITMSG when it has been automatically
determined. However, not all systems can produce valid
automatic identities.

Prior to f20f387 (commit: check committer identity more
strictly), this test worked even when we did not have a
valid automatic identity, since it did not run the strict
test until after we had generated the template. That commit
tightened the check to fail early (since we would fail
later, anyway), meaning that systems without a valid GECOS
name or hostname would fail the test.

We cannot just work around this, because it depends on
configuration outside the control of the test script.
Therefore we introduce a new test_prerequisite to run this
test only on systems where automatic ident works at all.

As a result, we can drop the confusing test_must_fail bit
from the test. The intent was that by giving "git commit"
invalid input (namely, nothing to commit), that it would
stop at a predictable point, whether we had a valid identity
or not, from which we could view the contents of
COMMIT_EDITMSG. Since that assumption no longer holds, and
we can only run the test when we have a valid identity,
there is no reason not to let commit run to completion. That
lets us be more robust to other unforeseen failures.

t7502: drop confusing test_might_fail callJeff King Thu, 26 Jul 2012 20:31:15 +0000 (16:31 -0400)

t7502: drop confusing test_might_fail call

In t7502.20, we run "git commit" and check that it warns us
that the author and committer identity are not the same
(this is always the case in the test environment, since we
set up the idents differently).

Instead of actually making a commit, we have a clean index,
so the "git commit" we run will fail. This is marked as
might_fail, which is not really correct; it will always fail
since there is nothing to commit.

However, the only reason not to do a complete commit would
be to see the intermediate state of the COMMIT_EDITMSG file
when the commit is not completed. We don't need to care
about this, though; even a complete commit will leave
COMMIT_EDITMSG for us to view. By doing a real commit and
dropping the might_fail, we are more robust against other
unforeseen failures of "git commit" that might influence our
test result.

It might seem less robust to depend on the fact that "git
commit" leaves COMMIT_EDITMSG in place after a successful
commit. However, that brings this test in line with others
parts of the script, which make the same assumption.
Furthermore, if that ever does change, the right solution is
not to prevent commit from completing, but to set EDITOR to
a script that will record the contents we see. After all,
the point of these tests is to check what the user sees in
their EDITOR, so that would be the most direct test. For
now, though, we can continue to use the "shortcut" that
COMMIT_EDITMSG is left intact.

t7502: properly quote GIT_EDITORJeff King Thu, 26 Jul 2012 20:28:00 +0000 (16:28 -0400)

t7502: properly quote GIT_EDITOR

One of the tests tries to ensure that editor is not run due
to an early failure. However, it needs to quote the pathname
of the trash directory used in $GIT_EDITOR, since git will
pass it along to the shell. In other words, the test would
pass whether the code was correct or not, since the unquoted
editor specification would never run.

We never noticed the problem because the code is indeed
correct, so git-commit never even tried to run the editor.

t7502: clean up fake_editor tests

Using write_script saves us a few lines of code, and means
we consistently use $SHELL_PATH.

We can also drop the setting of the $pwd variable from
$(pwd). In the first instance, there is no reason to use it
(we can just use $(pwd) directly two lines later, since we
are interpolating the here-document). In the second
instance, it is totally pointless and probably just a
cut-and-paste from the first instance.

Finally, we can use a non-interpolating here document for
the final script, which saves some quoting.

checkout: don't confuse ref and object flagsJeff King Wed, 25 Jul 2012 21:57:30 +0000 (17:57 -0400)

checkout: don't confuse ref and object flags

When we are leaving a detached HEAD, we do a revision traversal to
check whether we are orphaning any commits, marking the commit we're
leaving as the start of the traversal, and all existing refs as
uninteresting.

Prior to commit 468224e5, we did so by calling for_each_ref, and
feeding each resulting refname to setup_revisions. Commit 468224e5
refactored this to simply mark the pending objects, saving an extra
lookup.

However, it confused the "flags" parameter to the each_ref_fn
clalback, which is about the flags we found while looking up the ref
with the object flag. Because REF_ISSYMREF ("this ref is a symbolic
ref, e.g. refs/remotes/origin/HEAD") happens to be the same bit
pattern as SEEN ("we have picked this object up from the pending
list and moved it to revs.commits list"), we incorrectly reported
that a commit previously at the detached HEAD will become
unreachable if the only ref that can reach the commit happens to be
pointed at by a symbolic ref.

git-submodule: work with GIT_DIR/GIT_WORK_TREE

The combination of GIT_DIR and GIT_WORK_TREE can be used to manage
files in one directory hierarchy while keeping the repository that
keeps track of them outside the directory hierarchy. For example:

git init --bare /path/to/there
alias dotfiles="GIT_DIR=/path/to/there GIT_WORK_TREE=/path/to/here git"

cd /path/to/here
dotfiles add file
dotfiles commit -a -m "add /path/to/here/file"
...

lets you manage files under /path/to/here/ in the repository located
at /path/to/there.

git-submodule however fails to add submodules, as it is confused by
GIT_DIR and GIT_WORK_TREE environment variables when it tries to
work in the submodule, like so:

dotfiles submodule add http://path.to/submodule
fatal: working tree '/path/to/here' already exists.

Simply unsetting the environment where the command works on the
submodule is sufficient to fix this, as it has set things up so
that GIT_DIR and GIT_WORK_TREE do not even have to point at the
repository and the working tree of the submodule.

reasons:

1. Apache complains about following the symbolic link from

2. Apache does not pass through the GIT_VALGRIND variable
to the backend CGI.

This patch fixes both problems. Unfortunately, there is a
slight hack we need to handle passing environment variables
through Apache. If we just tell it:

PassEnv GIT_VALGRIND

then Apache will complain when GIT_VALGRIND is not set. If
we try:

SetEnv GIT_VALGRIND ${GIT_VALGRIND}

then when GIT_VALGRIND is not set, it will pass through the
literal "${GIT_VALGRIND}". Instead, we now unconditionally
pass through GIT_VALGRIND from lib-httpd.sh into apache,
even if it is empty.

commit: document the temporary commit message file

We do not document COMMIT_EDITMSG at all, but users may want
to know about it for two reasons:

1. They may want to tell their editor to configure itself
for formatting a commit message.

2. If a commit is aborted by an error, the user may want
to recover the commit message they typed.

Let's put a note in git-commit(1).

commit: check committer identity more strictlyJeff King Mon, 23 Jul 2012 18:50:35 +0000 (14:50 -0400)

commit: check committer identity more strictly

The identity of the committer will ultimately be pulled from
the ident code by commit_tree(). However, we make an attempt
to check the author and committer identity early, before the
user has done any manual work like inputting a commit
message. That lets us abort without them having to worry
about salvaging the work from .git/COMMIT_EDITMSG.

The early check for committer ident does not use the
IDENT_STRICT flag, meaning that it would not find an empty
name field. The motivation was presumably because we did not
want to be too restrictive, as later calls might be more lax
(for example, when we create the reflog entry, we do not
care too much about a real name). However, because
commit_tree will always get a strict identity to put in the
commit object itself, there is no point in being lax only to
die later (and in fact it is harmful, because the user will
have wasted time typing their commit message).

Incidentally, this bug was masked prior to 060d4bb, as the
initial loose call would taint the later strict call. So the
commit would succeed (albeit with a bogus committer line in
the commit object), and nobody noticed that our early check
did not match the later one.

advice: pass varargs to strbuf_vaddf, not strbuf_addfJeff King Mon, 23 Jul 2012 18:48:57 +0000 (14:48 -0400)

advice: pass varargs to strbuf_vaddf, not strbuf_addf

The advise() function takes a variable number of arguments
and converts them into a va_list object to pass to strbuf
for handling. However, we accidentally called strbuf_addf
(that takes a variable number of arguments) instead of
strbuf_vaddf (that takes a va_list).

This bug dates back to v1.7.8.1-1-g23cb5bf, but we never
noticed because none of the current callers passes a string
with a format specifier in it. And the compiler did not
notice because the format string is not available at
compile time.

Makefile: BLK_SHA1 does not require fast htonl() and unaligned loads

block-sha1/ is fast on most known platforms. Clarify the Makefile to
be less misleading about that.

Early versions of block-sha1/ explicitly relied on fast htonl() and
fast 32-bit loads with arbitrary alignment. Now it uses those on some
arches but the default behavior is byte-at-a-time access for the sake
of arches like ARM, Alpha, and their kin and it is still pretty fast
on these arches (fast enough to supersede the mozilla SHA1
implementation and the hand-written ARM assembler implementation that
were bundled before).

block-sha1: avoid pointer conversion that violates... Jonathan Nieder Sun, 22 Jul 2012 23:39:54 +0000 (18:39 -0500)

block-sha1: avoid pointer conversion that violates alignment constraints

With 660231aa (block-sha1: support for architectures with memory
alignment restrictions, 2009-08-12), blk_SHA1_Update was modified to
access 32-bit chunks of memory one byte at a time on arches that
prefer that:

#define get_be32(p) ( \
(*((unsigned char *)(p) + 0) << 24) | \
(*((unsigned char *)(p) + 1) << 16) | \
(*((unsigned char *)(p) + 2) << 8) | \
(*((unsigned char *)(p) + 3) << 0) )

The code previously accessed these values by just using htonl(*p).

Unfortunately, Michael noticed on an Alpha machine that git was using
plain 32-bit reads anyway. As soon as we convert a pointer to int *,
the compiler can assume that the object pointed to is correctly
aligned as an int (C99 section 6.3.2.3 "pointer conversions"
paragraph 7), and gcc takes full advantage by using a single 32-bit
load, resulting in a whole bunch of unaligned access traps.

So we need to obey the alignment constraints even when only dealing
with pointers instead of actual values. Do so by changing the type
of 'data' to void *. This patch renames 'data' to 'block' at the same
time to make sure all references are updated to reflect the new type.

build: "make clean" should not remove configure-generated files

Those filed hold variables, settings and information set by the
configuration process run by './configure'; in Autotools-based
build system that kind of stuff should only be removed by
"make distclean". Having it removed by "make clean" is not only
inconsistent, but causes real confusion for that part of the Git
audience that is used to the Autotools semantics; for example,
an autotools old-timer that has run:

./configure --prefix /opt/git

in the past, without running "make distclean" afterwards, would
expect a "make install" issued after a "make clean" to rebuild and
install git in '/opt/git'; but with the current behaviour, the
"make clean" invocation removes (among the other things) the file
'config.mak.autogen', so that the "make install" falls back to the
default prefix of '$HOME', thus installing git in the user's home
directory -- definitely unexpected.

diff: test precedence of external diff driversJeff King Thu, 19 Jul 2012 11:49:38 +0000 (07:49 -0400)

diff: test precedence of external diff drivers

There are three ways to specify an external diff command:
GIT_EXTERNAL_DIFF in the environment, diff.external in the
config, or a "diff" gitattribute. The current order of
precedence is:

1. gitattribute

2. GIT_EXTERNAL_DIFF

3. diff.external

Usually our rule is that environment variables should take
precedence over on-disk config (i.e., option 2 should come
before option 1). However, this situation is trickier than
some, because option 1 is more specific to the individual
file than option 2 (which affects all files), so it might be
preferable. So the current behavior can be seen as
implementing "do the specific thing if we can, but fall back
to this general thing".

This is probably not what we would do if we were writing git
from scratch, but it has been this way for several years,
and is not worth changing. So let's at least document that
this is the way it's supposed to work with a test.

While we're there, let's also make sure that diff.external
(which was not previously tested at all) works by running it
through the same tests as GIT_EXTERNAL_DIFF.

git-svn: don't create master if another head existsMarcin Owsiany Sun, 24 Jun 2012 21:40:05 +0000 (22:40 +0100)

git-svn: don't create master if another head exists

git-svn insists on creating the "master" head (unless it exists) on every
"fetch". It is useful that it gets created initially, when no head exists
- users expect this git convention of having a "master" branch on initial
clone.

However creating it when there already is another head does not provide any
value - the ref is never updated, so it just gets stale after a while. Also,
some users find it annoying that it gets recreated, especially when they would
like the git branch names to follow SVN repository branch names. More
background in http://thread.gmane.org/gmane.comp.version-control.git/115030

Make git-svn skip the "master" creation if HEAD already points at a valid head.
This means "master" does get created on initial "clone" but does not get
recreated once a user deletes it.

Also, make post_fetch_checkout work with any head that is pointed to by HEAD,
not just "master".

Also, use fatal error handling consistent with the rest of the program for
post_fetch_checkout.

credential: convert "url" attribute into its parsed subparts

The git-credential command requires that you feed it a
broken-down credential, which means that the client needs to
parse a URL itself. Since we have our own URL-parsing
routines, we can easily allow the caller to just give us the
URL as-is, saving them some code.

mw-to-git: check blank credential attributes via length

When writing a credential to git-credential, we omit fields
that do not have a true value. This will skip empty or
undefined fields (which we want), but will also accidentally
skip usernames or passwords which happen to have a non-true
value (e.g., "0"). Be more careful by checking for non-zero
length.

docs/credential: minor clarity fixups

The text in git-credential(1) was copied from
technical/api-credentials, so it still talks about the
input/output format as coming from git to the helper. Since
the surrounding text already indicates that this format is
used for reading and writing with git credential, we can
just remove the extraneous confusing bits.

diff: correctly disable external_diff with --no-ext... Junio C Hamano Wed, 18 Jul 2012 05:08:59 +0000 (22:08 -0700)

diff: correctly disable external_diff with --no-ext-diff

Upon seeing a type-change filepair, "diff --no-ext-diff" does not
show the usual "deletion followed by addition" split patch and does
not run the external diff driver either.

This is because the logic to disable external diff was placed at a
wrong level in the callchain. run_diff_cmd() decides to show the
split patch only when external diff driver is not configured or
specified via GIT_EXTERNAL_DIFF environment, but this is done before
checking if --no-ext-diff was given. To make things worse,
run_diff_cmd() checks --no-ext-diff and disables the output for such
a filepair completely, as the callchain below it (e.g. builtin_diff)
does not want to handle typechange filepairs.

commit-tree: resurrect command line parsing updates

79a9312 (commit-tree: update the command line parsing, 2011-11-09)
updated the command line parser to understand the usual "flags first
and then non-flag arguments" order, in addition to the original and
a bit unusual "tree comes first and then zero or more -p <parent>".

Unfortunately, ba3c69a (commit: teach --gpg-sign option, 2011-10-05)
broke it by mistake. Resurrect it, and protect the feature with a
test from future breakages.

git-remote-mediawiki: allow page names with a ':'

Traditionnally, pages named Foo:Bar are page 'Bar' in namespace 'Foo'.
However, it is also possible to call a page Foo:Bar if 'Foo' is not a
namespace. In this case, the actual name of the page is 'Foo:Bar', in the
main namespace. Since we can't tell with only the filename, query the
wiki for a namespace 'Foo' in these cases, but deal with the case where
no such namespace is found.

For some reason, 'echo X | dd bs=1k seek=1' creates a file with 2050 bytes
on Windows instead of the expected 1026 bytes, so that a test fails. Since
the actual contents of the file are irrelevant as long as there is at
least one zero byte so that the diff machinery recognizes it as binary,
use printf to generate it.
