Git 2.0: git svn: Set default --prefix='origin/' if... Johan Herland Fri, 11 Oct 2013 12:57:07 +0000 (14:57 +0200)

Git 2.0: git svn: Set default --prefix='origin/' if --prefix is not given

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.)

i18n: only extract comments marked with "TRANSLATORS:"

When extract l10n messages, we use "--add-comments" option to keep
comments right above the l10n messages for references. But sometimes
irrelevant comments are also extracted. For example in the following
code block, the comment in line 2 will be extracted as comment for the
l10n message in line 3, but obviously it's wrong.

{ OPTION_CALLBACK, 0, "ignore-removal", &addremove_explicit,
NULL /* takes no arguments */,
N_("ignore paths removed in the working tree (same as
--no-all)"),
PARSE_OPT_NOARG, ignore_removal_cb },

Since almost all comments for l10n translators are marked with the same
prefix (tag): "TRANSLATORS:", it's safe to only extract comments with
this special tag. I.E. it's better to call xgettext as:

xgettext --add-comments=TRANSLATORS: ...

Also tweaks the multi-line comment in "init-db.c", to make it start with
the proper tag, not "* TRANSLATORS:" (which has a star before the tag).

This reverts commit 99855ddf4bd319cd06a0524e755ab1c1b7d39f3b.

The workaround 99855ddf introduced to deal with problematic
"return" statements in scripts run by "dot" commands located
inside functions only handles one part of the problem. The
issue has now been addressed by not using "return" statements
in this way in the git-rebase--*.sh scripts.

This workaround is therefore no longer necessary, so clean
up the code by reverting it.

rebase: avoid non-function use of "return" on FreeBSDKyle J. McKay Fri, 11 Apr 2014 08:28:17 +0000 (01:28 -0700)

rebase: avoid non-function use of "return" on FreeBSD

Since a1549e10, 15d4bf2e and 01a1e646 (first appearing in v1.8.4)
the git-rebase--*.sh scripts have used a "return" to stop execution
of the dot-sourced file and return to the "dot" command that
dot-sourced it. The /bin/sh utility on FreeBSD however behaves
poorly under some circumstances when such a "return" is executed.

In particular, if the "dot" command is contained within a function,
then when a "return" is executed by the script it runs (that is not
itself inside a function), control will return from the function
that contains the "dot" command skipping any statements that might
follow the dot command inside that function. Commit 99855ddf (first
appearing in v1.8.4.1) addresses this by making the "dot" command
the last line in the function.

Unfortunately the FreeBSD /bin/sh may also execute some statements
in the script run by the "dot" command that appear after the
troublesome "return". The fix in 99855ddf does not address this
problem.

For example, if you have script1.sh with these contents:

run_script2() {
. "$(dirname -- "$0")/script2.sh"
_e=$?

[ $_e -eq 5 ] || echo expected status 5 got $_e
return 3
}
run_script2
e=$?
[ $e -eq 3 ] || { echo expected status 3 got $e; exit 1; }

And script2.sh with these contents:

if [ 5 -gt 3 ]; then
return 5
fi
case bad in *)
echo always shows
esac
echo should not get here
! :

When running script1.sh (e.g. '/bin/sh script1.sh' or './script1.sh'
after making it executable), the expected output from a POSIX shell
is simply the single line:

only this line should show

However, when run using FreeBSD's /bin/sh, the following output
appears instead:

should not get here
expected status 3 got 1

Not only did the lines following the "dot" command in the run_script2
function in script1.sh get skipped, but additional lines in script2.sh
following the "return" got executed -- but not all of them (e.g. the
"echo always shows" line did not run).

These issues can be avoided by not using a top-level "return" in
script2.sh. If script2.sh is changed to this:

main() {
if [ 5 -gt 3 ]; then
return 5
fi
case bad in *)
echo always shows
esac
echo should not get here
! :
}
main

Then it behaves the same when using FreeBSD's /bin/sh as when using
other more POSIX compliant /bin/sh implementations.

We fix the git-rebase--*.sh scripts in a similar fashion by moving
the top-level code that contains "return" statements into its own
function and then calling that as the last line in the script.

Makefile: use curl-config to determine curl flags

curl-config should always be installed alongside a curl distribution,
and its purpose is to provide flags for building against libcurl, so
use it instead of guessing flags and dependent libraries.

Allow overriding CURL_CONFIG to a custom path to curl-config, to
compile against a curl installation other than the first in PATH.

Depending on the set of features curl is compiled with, there may be
more libraries required than the previous two options of -lssl and
-lidn. For example, with a vanilla build of libcurl-7.36.0 on Mac OS X
10.9:

$ ~/d/curl-out-7.36.0/lib/curl-config --libs
-L/Users/dborowitz/d/curl-out-7.36.0/lib -lcurl -lgssapi_krb5 -lresolv -lldap -lz

Use this only when CURLDIR is not explicitly specified, to continue
supporting older builds.

transport-helper: fix sync issue on crashesFelipe Contreras Sat, 12 Apr 2014 20:33:32 +0000 (15:33 -0500)

transport-helper: fix sync issue on crashes

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.

test: fix t5560 on FreeBSDKyle J. McKay Fri, 11 Apr 2014 08:28:19 +0000 (01:28 -0700)

test: fix t5560 on FreeBSD

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.

test: fix t7001 cp to use POSIX options

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.

completion: fix completing args of aliased "push", "fetch", etc.

Some commands need the first word to determine the actual action that is
being executed, however, the command is wrong when we use an alias, for
example 'alias.p=push', if we try to complete 'git p origin ', the
result would be wrong because __git_complete_remote_or_refspec() doesn't
know where it came from.

So let's override words[1], so the alias 'p' is override by the actual
command, 'push'.

utf8.c: partially update to version 6.3

Unicode 6.3 defines more code points as combining or accents. For
example, the character "ö" could be expressed as an "o" followed by
U+0308 COMBINING DIARESIS (aka umlaut, double-dot-above). We should
consider that such a sequence of two codepoints occupies one display
column for the alignment purposes, and for that, git_wcwidth()
should return 0 for them. Affected codepoints are:

U+0358..U+035C
U+0487
U+05A2, U+05BA, U+05C5, U+05C7
U+0604, U+0616..U+061A, U+0659..U+065F

Earlier unicode standards had defined these as "reserved".

Only the range 0..U+07FF has been checked to see which codepoints
need to be marked as 0-width while preparing for this commit; more
updates may be needed.

pack-objects: do not reuse packfiles without --delta... Jeff King Wed, 2 Apr 2014 06:39:17 +0000 (02:39 -0400)

pack-objects: do not reuse packfiles without --delta-base-offset

When we are sending a packfile to a remote, we currently try
to reuse a whole chunk of packfile without bothering to look
at the individual objects. This can make things like initial
clones much lighter on the server, as we can just dump the
packfile bytes.

However, it's possible that the other side cannot read our
packfile verbatim. For example, we may have objects stored
as OFS_DELTA, but the client is an antique version of git
that only understands REF_DELTA. We negotiate this
capability over the fetch protocol. A normal pack-objects
run will convert OFS_DELTA into REF_DELTA on the fly, but
the "reuse pack" code path never even looks at the objects.

This patch disables packfile reuse if the other side is
missing any capabilities that we might have used in the
on-disk pack. Right now the only one is OFS_DELTA, but we
may need to expand in the future (e.g., if packv4 introduces
new object types).

We could be more thorough and only disable reuse in this
case when we actually have an OFS_DELTA to send, but:

1. We almost always will have one, since we prefer
OFS_DELTA to REF_DELTA when possible. So this case
would almost never come up.

2. Looking through the objects defeats the purpose of the
optimization, which is to do as little work as possible
to get the bytes to the remote.

add `ignore_missing_links` mode to revwalkVicent Marti Fri, 28 Mar 2014 10:00:43 +0000 (06:00 -0400)

add `ignore_missing_links` mode to revwalk

When pack-objects is computing the reachability bitmap to
serve a fetch request, it can erroneously die() if some of
the UNINTERESTING objects are not present. Upload-pack
throws away HAVE lines from the client for objects we do not
have, but we may have a tip object without all of its
ancestors (e.g., if the tip is no longer reachable and was
new enough to survive a `git prune`, but some of its
reachable objects did get pruned).

In the non-bitmap case, we do a revision walk with the HAVE
objects marked as UNINTERESTING. The revision walker
explicitly ignores errors in accessing UNINTERESTING commits
to handle this case (and we do not bother looking at
UNINTERESTING trees or blobs at all).

When we have bitmaps, however, the process is quite
different. The bitmap index for a pack-objects run is
calculated in two separate steps:

First, we perform an extensive walk from all the HAVEs to
find the full set of objects reachable from them. This walk
is usually optimized away because we are expected to hit an
object with a bitmap during the traversal, which allows us
to terminate early.

Secondly, we perform an extensive walk from all the WANTs,
which usually also terminates early because we hit a commit
with an existing bitmap.

Once we have the resulting bitmaps from the two walks, we
AND-NOT them together to obtain the resulting set of objects
we need to pack.

When we are walking the HAVE objects, the revision walker
does not know that we are walking it only to mark the
results as uninteresting. We strip out the UNINTERESTING flag,
because those objects _are_ interesting to us during the
first walk. We want to keep going to get a complete set of
reachable objects if we can.

We need some way to tell the revision walker that it's OK to
silently truncate the HAVE walk, just like it does for the
UNINTERESTING case. This patch introduces a new
`ignore_missing_links` flag to the `rev_info` struct, which
we set only for the HAVE walk.

It also adds tests to cover UNINTERESTING objects missing
from several positions: a missing blob, a missing tree, and
a missing parent commit. The missing blob already worked (as
we do not care about its contents at all), but the other two
cases caused us to die().

Note that there are a few cases we do not need to test:

1. We do not need to test a missing tree, with the blob
still present. Without the tree that refers to it, we
would not know that the blob is relevant to our walk.

2. We do not need to test a tip commit that is missing.
Upload-pack omits these for us (and in fact, we
complain even in the non-bitmap case if it fails to do
so).
