gitweb: Fix project-specific feature override behaviorJakub Narebski Mon, 1 Mar 2010 21:51:34 +0000 (22:51 +0100)

gitweb: Fix project-specific feature override behavior

This commit fixes a bug in processing project-specific override in
a situation when there is no project, e.g. for the projects list page.

When 'snapshot' feature had project specific config override enabled
by putting
$feature{'snapshot'}{'override'} = 1;

(or equivalent) in $GITWEB_CONFIG, and when viewing toplevel gitweb
page, which means the projects list page (to be more exact this
happens for any project-less action), gitweb would put the following
Perl warnings in error log:

gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2065.
fatal: error processing config file(s)
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2221.
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2218.

The problem is in the following fragment of code:

# path to the current git repository
our $git_dir;
$git_dir = "$projectroot/$project" if $project;

# list of supported snapshot formats
our @snapshot_fmts = gitweb_get_feature('snapshot');
@snapshot_fmts = filter_snapshot_fmts(@snapshot_fmts);

For the toplevel gitweb page, which is the list of projects, $project is not
defined, therefore neither is $git_dir. gitweb_get_feature() subroutine
calls git_get_project_config() if project specific override is turned
on... but we don't have project here.

Those errors mentioned above occur in the following fragment of code in
git_get_project_config():

# get config
if (!defined $config_file ||
$config_file ne "$git_dir/config") {
%config = git_parse_project_config('gitweb');
$config_file = "$git_dir/config";
}

git_parse_project_config() calls git_cmd() which has '--git-dir='.$git_dir

There are (at least) three possible solutions:
1. Harden gitweb_get_feature() so that it doesn't call
git_get_project_config() if $project (and therefore $git_dir) is not
defined; there is no project for project specific config.
2. Harden git_get_project_config() like you did in your fix, returning early
if $git_dir is not defined.
3. Harden git_cmd() so that it doesn't add "--git-dir=$git_dir" if $git_dir
is not defined, and change git_get_project_config() so that it doesn't
even try to access $git_dir if it is not defined.

This commit implements both 1.) and 2.), i.e. gitweb_get_feature() doesn't
call project-specific override if $git_dir is not defined (if there is no
project), and git_get_project_config() returns early if $git_dir is not
defined.

Add a test for this bug to t/t9500-gitweb-standalone-no-errors.sh test.

bisect: error out when passing bad path parametersChristian Couder Sun, 28 Feb 2010 22:19:09 +0000 (23:19 +0100)

bisect: error out when passing bad path parameters

As reported by Mark Lodato, "git bisect", when it was started with
path parameters that match no commit was kind of working without
taking account of path parameters and was reporting something like:

Bisecting: -1 revisions left to test after this (roughly 0 steps)

It is more correct and safer to just error out in this case, before
displaying the revisions left, so this patch does just that.

Note that this bug is very old, it exists at least since v1.5.5.
And it is possible to detect that case earlier in the bisect
algorithm, but it is not clear that it would be an improvement to
error out earlier, on the contrary it may change the behavior of
"git rev-list --bisect-all" for example, which is currently correct.

submodules: ensure clean environment when operating in a submodule

git-submodule used to take care of clearing GIT_DIR whenever it operated
on a submodule index or configuration, but forgot to unset GIT_WORK_TREE
or other repo-local variables. This would lead to failures e.g. when
GIT_WORK_TREE was set.

This only happened in very unusual contexts such as operating on the
main worktree from outside of it, but since "git-gui: set GIT_DIR and
GIT_WORK_TREE after setup" (a9fa11fe5bd5978bb) such failures could also
be provoked by invoking an external tool such as "git submodule update"
from the Git Gui in a standard setup.

Solve by using the newly introduced clear_local_git_env() shell function
to ensure that all repo-local environment variables are unset.

fetch --all/--multiple: keep all the fetched branch information

Since "git fetch" learned "--all" and "--multiple" options, it has become
tempting for users to say "git pull --all". Even though it may fetch from
remotes that do not need to be fetched from for merging with the current
branch, it is handy.

"git fetch" however clears the list of fetched branches every time it
contacts a different remote. Unless the current branch is configured to
merge with a branch from a remote that happens to be the last in the list
of remotes that are contacted, "git pull" that fetches from multiple
remotes will not be able to find the branch it should be merging with.

Make "fetch" clear FETCH_HEAD (unless --append is given) and then append
the list of branches fetched to it (even when --append is not given). That
way, "pull" will be able to find the data for the branch being merged in
FETCH_HEAD no matter where the remote appears in the list of remotes to be
contacted by "git fetch".

All of these tests were bogus, as they created new directory and tried to

with the repository in $TEST_DIRECTORY.

While fixing it, modernize the style not to chdir around outside of

and we need to chdir back to the test directory in each test, which is

When git am does an automatic gc it doesn't clean up the rebase-apply

aborts the gc then future am or rebase operations will report that an

add-interactive: fix bogus diff header line orderingJeff King Tue, 23 Feb 2010 01:05:44 +0000 (20:05 -0500)

add-interactive: fix bogus diff header line ordering

When we look at a patch for adding hunks interactively, we
first split it into a header and a list of hunks. Some of
the header lines, such as mode changes and deletion, however,
become their own selectable hunks. Later when we reassemble
the patch, we simply concatenate the header and the selected
hunks. This leads to patches like this:

diff --git a/file b/file
index d95f3ad..0000000
--- a/file
+++ /dev/null
deleted file mode 100644
@@ -1 +0,0 @@
-content

Notice how the deletion comes _after_ the ---/+++ lines,
when it should come before.

In many cases, we can get away with this as git-apply
accepts the slightly bogus input. However, in the specific
case of a deletion line that is being applied via "apply
-R", this malformed patch triggers an assert in git-apply.
This comes up when discarding a deletion via "git checkout
-p".

Rather than try to make git-apply accept our odd input,
let's just reassemble the patch in the correct order.

other permission bits to the umask. This usually has the same effect
as a normal file creation with a umask.

But in the presence of ACLs, the group permission plays the role of
the ACL mask: the "g" bits of newly created files are chosen according
to default ACL mask of the directory, not according to the umask, and
doing a chmod() on these "g" bits affect the ACL's mask instead of
actual group permission.

In other words, creating files with 0600 and then doing a chmod to the
umask creates files which are unreadable by users allowed in the
default ACL. To create the files without breaking ACLs, we let the
umask do it's job at the file's creation time, and get rid of the
later chmod.

gitmkstemps emulates the behavior of mkstemps, which is usually used

Add a testcase for ACL with restrictive umask.

Right now, Git creates unreadable pack files on non-shared
repositories when the user has a umask of 077, even when the default

Loose object files are created world-readable, which doesn't break ACLs,

tests: Fix race condition in t7006-pager

Pagers that do not consume their input are dangerous: for example,

$ GIT_PAGER=: git log
$ echo $?
141
$

The only reason these tests were able to work before was that
'git log' would write to the pipe (and not fill it) before the
pager had time to terminate and close the pipe.

Fix it by using a program that consumes its input, namely wc (as
suggested by Johannes).

sha1_file: be paranoid when creating loose objectsNicolas Pitre Sun, 21 Feb 2010 20:48:06 +0000 (15:48 -0500)

sha1_file: be paranoid when creating loose objects

We don't want the data being deflated and stored into loose objects
to be different from what we expect. While the deflated data is
protected by a CRC which is good enough for safe data retrieval
operations, we still want to be doubly sure that the source data used
at object creation time is still what we expected once that data has
been deflated and its CRC32 computed.

The most plausible data corruption may occur if the source file is
modified while Git is deflating and writing it out in a loose object.
Or Git itself could have a bug causing memory corruption. Or even bad
RAM could cause trouble. So it is best to make sure everything is
coherent and checksum protected from beginning to end.

To do so we compute the SHA1 of the data being deflated _after_ the
deflate operation has consumed that data, and make sure it matches
with the expected SHA1. This way we can rely on the CRC32 checked by
the inflate operation to provide a good indication that the data is still
coherent with its SHA1 hash. One pathological case we ignore is when
the data is modified before (or during) deflate call, but changed back
before it is hashed.

There is some overhead of course. Using 'git add' on a set of large files:

Before:

real 0m25.210s
user 0m23.783s
sys 0m1.408s

After:

real 0m26.537s
user 0m25.175s
sys 0m1.358s

The overhead is around 5% for full data coherency guarantee.

sha1_file: don't malloc the whole compressed result when writing out objects

There is no real advantage to malloc the whole output buffer and
deflate the data in a single pass when writing loose objects. That is
like only 1% faster while using more memory, especially with large
files where memory usage is far more. It is best to deflate and write
the data out in small chunks reusing the same memory instead.

For example, using 'git add' on a few large files averaging 40 MB ...

t7006-pager: if stdout is not a terminal, make a new one

Testing pagination requires (fake or real) access to a terminal so we
can see whether the pagination automatically kicks in, which makes it
hard to get good coverage when running tests without --verbose. There
are a number of ways to work around that:

- Replace all isatty calls with calls to a custom xisatty wrapper
that usually checks for a terminal but can be overridden for tests.
This would be workable, but it would require implementing xisatty
separately in three languages (C, shell, and perl) and making sure
that any code that is to be tested always uses the wrapper.

- Redirect stdout to /dev/tty. This would be problematic because
there might be no terminal available, and even if a terminal is
available, it might not be appropriate to spew output to it.

- Create a new pseudo-terminal on the fly and capture its output.

This patch implements the third approach.

The new test-terminal.perl helper uses IO::Pty from Expect.pm to create
a terminal and executes the program specified by its arguments with
that terminal as stdout. If the IO::Pty module is missing or not
working on a system, the test script will maintain its old behavior
(skipping most of its tests unless GIT_TEST_OPTS includes --verbose).

cherry_pick_list: quit early if one side is empty

The --cherry-pick logic starts by counting the commits on each side,
so that it can filter away commits on the bigger one. However, so
far it missed an opportunity for optimization: it doesn't need to do
any work if either side is empty.

This in particular helps the common use-case 'git rebase -i HEAD~$n':
it internally uses --cherry-pick, but since HEAD~$n is a direct
ancestor the left side is always empty.

tests: Add tests for automatic use of pager

Git’s automatic pagination support has some subtleties. Add some
tests to make sure we don’t break:

- when git will use a pager by default;
- the effect of the --paginate and --no-pager options;
- the effect of pagination on use of color;
- how the choice of pager is configured.

This does not yet test:

- use of pager by scripted commands (git svn and git am);
- effect of the pager.* configuration variables;
- setting of the LESS variable.

Some features involve checking whether stdout is a terminal, so many
of these tests are skipped unless output is passed through to the
terminal (i.e., unless $GIT_TEST_OPTS includes --verbose).

The immediate purpose for these tests was to avoid making things worse
after the breakage from my jn/editor-pager series (see commit 376f39,
2009-11-20). Thanks to Sebastian Celis <sebastian@sebastiancelis.com>

utf8.c: speculatively assume utf-8 in strbuf_add_wrappe... René Scharfe Fri, 19 Feb 2010 22:20:44 +0000 (23:20 +0100)

utf8.c: speculatively assume utf-8 in strbuf_add_wrapped_text()

is_utf8() works by calling utf8_width() for each character at the
supplied location. In strbuf_add_wrapped_text(), we do that anyway
while wrapping the lines. So instead of checking the encoding
beforehand, optimistically assume that it's utf-8 and wrap along
until an invalid character is hit, and when that happens start over.

This pays off if the text consists only of valid utf-8 characters.
The following command was run against the Linux kernel repo with
git 1.7.0:

$ time git log --format='%b' v2.6.32 >/dev/null

real 0m2.679s
user 0m2.580s
sys 0m0.100s

$ time git log --format='%w(60,4,8)%b' >/dev/null

real 0m4.342s
user 0m4.230s
sys 0m0.110s

And with this patch series:

$ time git log --format='%w(60,4,8)%b' >/dev/null

real 0m3.741s
user 0m3.630s
sys 0m0.110s

So the cost of wrapping is reduced to 70% in this case.

docs: don't talk about $GIT_DIR/refs/ everywhere

It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we
may also consult the packed refs mechanism. These days we tend to treat
the "refs hierarchy" as more of an abstract namespace that happens to be
represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at
worst it can confuse users who then look in $GIT_DIR/refs and find that it
is missing some of the refs they expected to see.

This patch drops most uses of "$GIT_DIR/refs/*", changing them into just
"refs/*", under the assumption that users can handle the concept of an
abstract refs namespace. There are a few things to note:

- most cases just dropped the $GIT_DIR/ portion. But for cases where
that left _just_ the word "refs", I changed it to "refs/" to help
indicate that it was a hierarchy. I didn't do the same for longer
paths (e.g., "refs/heads" remained, instead of becoming
"refs/heads/").

- in some cases, no change was made, as the text was explicitly about
unpacked refs (e.g., the discussion in git-pack-refs).

- In some cases it made sense instead to note the existence of packed
refs (e.g., in check-ref-format and rev-parse).

Fix use of mutex in threaded grep

The program can decide at runtime not to use threading even if the support
is compiled in. In such a case, mutexes are not necessary and left
uninitialized. But the code incorrectly tried to take and release the
read_sha1_mutex unconditionally.

transport: add got_remote_refs flag

transport_get_remote_refs() in tranport.c checks transport->remote_refs
to determine whether transport->get_refs_list() should be invoked. The
logic is "if it is NULL, we haven't run ls-remote to find out yet".

However, transport->remote_refs could still be NULL while cloning from
an empty repository. This causes get_refs_list() to be run unnecessarily.

Introduce a flag, transport->got_remote_refs, to more explicitly record
if we have run transport->get_refs_list() already.

dwim_ref: fix dangling symref warning

If we encounter a symref that is dangling, in most cases we will warn
about it. The one exception is a dangling HEAD, as that indicates a
branch yet to be born.

However, the check in dwim_ref was not quite right. If we were fed
something like "HEAD^0" we would try to resolve "HEAD", see that it is
dangling, and then check whether the _original_ string we got was
"HEAD" (which it wasn't in this case). And that makes no sense; the
dangling thing we found was not "HEAD^0" but rather "HEAD".

Fixing this squelches a scary warning from "submodule summary HEAD" (and
consequently "git status" with status.submodulesummary set) in an empty
repo, as the submodule script calls "git rev-parse -q --verify HEAD^0".

git diff --quiet -w: check and report the statusLarry D'Anna Tue, 16 Feb 2010 06:55:21 +0000 (01:55 -0500)

git diff --quiet -w: check and report the status

The option -w tells the diff machinery to inspect the contents to set the
exit status, instead of checking the blob object level difference alone.
However, --quiet tells the diff machinery not to look at the contents, which
means DIFF_FROM_CONTENTS has no chance to inspect the change.

Work it around by calling diff_flush_patch() with output sent to /dev/null.

stash pop: remove 'apply' options during 'drop' invocationThomas Rast Mon, 15 Feb 2010 16:05:46 +0000 (17:05 +0100)

stash pop: remove 'apply' options during 'drop' invocation

The 'git stash pop' option parsing used to remove the first argument
in --index mode. At the time this was implemented, this first
argument was always --index. However, since the invention of the -q
option in fcdd0e9 (stash: teach quiet option, 2009-06-17) you can
cause an internal invocation of

git stash drop --index

by running

git stash pop -q --index

which then of course fails because drop doesn't know --index.

To handle this, instead let 'git stash apply' decide what the future
argument to 'drop' should be.

Warning: this means that 'git stash apply' must parse all options that
'drop' can take, and deal with them in the same way. This is
currently true for its only option -q.

am: Fix launching of pager

The pagination functionality in git am has some problems:

- It does not check if stdout is a tty, so it always paginates.

- If $GIT_PAGER uses any environment variables, they are being
ignored, since it does not run $GIT_PAGER through eval.

- If $GIT_PAGER is set to the empty string, instead of passing
output through to stdout, it tries to run $dotest/patch.

Fix them. While at it, move the definition of git_pager() to
git-sh-setup so authors of other commands are not tempted to
reimplement it with the same mistakes.

gitweb: Die if there are parsing errors in config file

Otherwise the errors can propagate, and show in damnest places, and
you would spend your time chasing ghosts instead of debugging real
problem (yes, it is from personal experience).

This follows (parts of) advice in `perldoc -f do` documentation.

This required restructoring code a bit, so we die only if we are reading
(executing) config file. As a side effect $GITWEB_CONFIG_SYSTEM is always
available, even when we use $GITWEB_CONFIG.

git svn: Fix launching of pager

In commit dec543e (am -i, git-svn: use "git var GIT_PAGER"), I tried
to teach git svn to defer to git var on what pager to use. In the
process, I introduced two bugs:

- The value set for $pager in config_pager has local scope, so
run_pager never sees it;

- git var cannot tell whether git svn’s output is going to a
terminal, so the value chosen for $pager does not reflect that
information.

Fix them.
