Ran optipng against cgit.png, which shrank file size by more than eight
percent. The image (including protocol overhead) should fit into a
single network packet now.
Optipng optimizes filters and compression. The actual pixel results are
not altered.

The starts_with() check was broken in two ways: For one thing, the
parameters were passed in the wrong order, for another thing,
starts_with() returns 1 if the string starts with the prefix (not 0).
Note that this bug existed since commit 02a545e (Add support for cloning
over http, 2008-08-06) but only pops in in corner cases.

When clicking on "log" from a tag we end up showing the log of whatever
branch we used to reach the tag. If the tag doesn't point onto a branch
then the tagged commit won't appear in this output.
By linking to tags with the head parameter instead of the "id" parameter
the log link will show the log of the tag. This is clearly desirable
when the tag has been reached from the refs UI and changing the
behaviour for tag decorations makes them match branch decorations where
log -> decoration -> log shows the log of the decoration.

Currently, when a user directly accesses the info command of a
repository, we exit cgit without printing anything to stdout, bringing
up error messages like "502 Bad Gateway" or "An error occurred while
reading CGI reply (no response received)". Instead of bailing out, at
least print the HTTP headers, including a reasonable error message.

Using (DIFF_FORMAT_DIFFSTAT | DIFF_FORMAT_PATCH) causes Git to emit a
"---" line between the commit message and the body of the patch, which
fixes a regression introduced in commit 455b598 (ui-patch.c: Use
log_tree_commit() to generate diffs, 2013-08-20), prior to which we
inserted the "---" line ourselves.
DIFF_FORMAT_SUMMARY is added so that we match the output of
git-format-patch(1) without the "-p" option.

Specifying a nonexistent README file via the readme option is sometimes
useful, e.g. when using scan-path and setting a global default.
Currently, we check whether there is only one option in the readme
option and, if so, we choose that file without checking whether it
exists. As a consequence, all repositories are equipped with an about
link in the aforementioned scenario, even if there is no about file.
Remove the early check for the number of keys and always check whether
the file exists instead.

It looks like cached patches are truncated to the nearest 1024-byte
boundary in the patch body. E.g.:
> mricon@nikko:[/tmp]$ wget -O no-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=6e1b4fdad5157bb9e88777d525704aba24389bee"
...
> 2014-06-11 15:34:51 (80.4 MB/s) - ‘no-cache’ saved [4767]
Patch is complete, without truncation. Next hit, with cache in place:
> mricon@nikko:[/tmp]$ wget -O yes-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=6e1b4
> fdad5157bb9e88777d525704aba24389bee"
...
> 2014-06-11 15:35:01 (17.0 MB/s) - ‘yes-cache’ saved [4096/4096]
Length truncated to 4096. The cache on disk looks truncated as well, so
the bug must me during the process of saving cache. The same is true for
larger patches:
> mricon@nikko:[/tmp]$ wget -O no-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=2840c566e95599cd60c7143762ca8b49d9395050"

...
> 2014-06-11 15:41:46 (1.05 MB/s) - ‘yes-cache’ saved [978944]
978944 (956KB exactly) with a cache-hit
Since the "html" functions use raw write(2) to STDIO_FILENO, we don't
notice problems with most pages, but raw patches write using printf(3).
This is fine if we're outputting straight to stdout since the buffers
are flushed on exit, but we close the cache output before this, so the
cached output ends up being truncated.
Make sure the buffers are flushed when we finish outputting a patch so
that we avoid this.
No other UIs use printf(3) so we do not need to worry about them.
Actually, it's slightly more interesting than this... since we don't set
GIT_FLUSH, Git decides whether or not it will flush stdout after writing
each commit based on whether or not stdout points to a regular file (in
maybe_flush_or_die()).
Which means that when writing directly to the webserver, Git flushes
stdout for us, but when we redirect stdout to the cache it points to a
regular file so Git no longer flushes the output for us.
The patch is still correct, but perhaps the full explanation is
interesting!

If you search for a bogus range string here:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/
Using something like "range" and "qwerty123456", it returns an "Internal
Server Error" and the following in the logs:
> [Tue Jun 10 17:45:32 2014] [error] [client 172.21.1.6] fatal:

The cache will kick in, so if you search for the same string again,
it'll show an empty range, so you have to change the bogus strings each
time.
This is because we just pass the arguments straight to Git's revision
parsing machinery which die()s if it cannot parse an argument, printing
the above to stderr and exiting.
The patch below makes it a bit friendlier by just ignoring unhandled
arguments, but I can't see an easy way to report errors when we can't
parse revision arguments without losing the flexibility of supporting
all of the revision specifiers supported by Git.

The check in parse_user that eventually makes it into committer_date and
tagger_date is:
else if (mode == 3 && isdigit(*p)) {
*date = atol(p);
mode++;
}
Since isdigit('-') is always false, date will never be negative. Thus
the sign of this function:
static int cmp_age(int age1, int age2)
{
if (age1 != 0 && age2 != 0)
return age2 - age1;
if (age1 == 0 && age2 == 0)
return 0;
if (age1 == 0)
return +1;
return -1;
}
Will always be the same as the sign of this function:
static inline int cmp_age(int age1, int age2)
{
return age2 - age1;
}

This can be used to specify the TTL for snapshots. Snapshots are usually
static and do not ever change. On the other hand, tarball generation is
CPU intensive.
One use case of this setting (apart from increasing the lifetime of

sendfile() does the same job and avoids to copy the content into userland

We favor LuaJIT over Lua. We disable Lua if neither can be found. We
error out if a particular Lua is specified via LUA_IMPLEMENTATION=JIT or
LUA_IMPLEMENTATION=VANILLA, but cannot be found. We print a status

Also, we do not link against libdl on the BSDs, since they include it as

Filters can now call hook_write and unhook_write if they want to
redirect writing to stdout to a different function. This saves us from
potential file descriptor pipes and other less efficient mechanisms.
We do this instead of replacing the call in html_raw because some places
stdlib's printf functions are used (ui-patch or within git itself),
which has its own internal buffering, which makes it difficult to
interlace our function calls. So, we dlsym libc's write and then
override it in the link stage.
While we're at it, we move considerations of argument count into the
generic new filter handler.

At some point, we're going to want to do lazy deallocation of filters.
For example, if we implement lua, we'll want to load the lua runtime
once for each filter, even if that filter is called many times.
Similarly, for persistent exec filters, we'll want to load it once,
despite many open_filter and close_filter calls, and only reap the child
process at the end of the cgit process. For this reason, we add here a
cleanup function that is called at the end of cgit's main().

Change the existing cgit_{open,close,fprintf}_filter functions to
delegate to filter-specific implementations accessed via function
pointers on the cgit_filter object.
We treat the "exec" filter type slightly specially here by putting its
structure definition in the header file and providing an "init" function
to set up the function pointers. This is required so that the
ui-snapshot.c code that applies a compression filter can continue to use
the filter interface to do so.

- Switched back to python2 according to a problem in pygments with python3.
With the next release of pygments this problem should be fixed.
Issue see here:
https://bitbucket.org/birkenfeld/pygments-main/issue/901/problems-with-python3
- Just read the stdin, decode it to utf-8 and ignore unknown signs. This ensures
that even destroyed files do not cause any errors in the filter.
- Improved language guessing:
-> At first use guess_lexer_for_filename for a better detection of the used
programming languages (even mixed cases will be detected, e.g. php + html).
-> If nothing was found look if there is a shebang and use guess_lexer.
-> As default/fallback choose TextLexer.

Valgrind says:

==18344== Uninitialised value was created by a stack allocation
==18344== at 0x40738B: cache_ls (cache.c:375)
This is caused by the keylen field being used to calculate whether or
not a slot is matched. We never then check the value of this and the
length of data read depends on the key length read from the file so this
isn't dangerous, but it's nice to avoid branching based on uninitialized
data.

Since the introduction of selective snapshot format configuration in
dc3c9b5 (allow selective enabling of snapshots, 2007-07-21), we allowed
seven different delimiters for snapshot formats, while the documentation
has always been clear about spaces being the only valid delimiter:
The value is a space-separated list of zero or more of the values
"tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".

Currently line numbers look like (for blob view and sdiff respectively):
<a class='no' id='n68' name='n68' href='#n68'>68</a>
<td class='lineno'><a class='no' href='...#n1' id='n1' name='n1'>1</a></td>
name=".." is unnecessary if the id attribute is set (this even applies
to IE6), so drop it. (aside, in HTML5, the name attribute is gone.)
The line number links can be selected through their parent classes, no
need for another class "no", so drop it too.
For a file with 2000 lines, this yields a saving of 40% (29% gzipped).

Features:
- update to git v1.8.3.
- expanded set of default filters to include markdown, restructuredtext, and
man pages.
- better sample configuration file in man page.
- "readme" may now be specified multiple times, and cgit will choose the first
one it finds.
- "readme" no longer needs a branch name. If prefixed with simply ":" it will
use the default branch.
- "branch-sort" allowing branches to be sorted either by "age" or "name", for
kernel.org.
- "enable-index-owner" allowing the owner column to be disabled in the index
page.
- print submodule revision next to submodule link.
- integrate more closely with git apis, such as strbuf.
- rely on git test harness and git makefiles.

- pager navigation is now unordered list.
- span tag wraps commit directions.
Behavior changes:
- HOME is no longer passed as an environment variable to any filter api
scripts.

Using the url= query string, it was possible request arbitrary files
from the filesystem if the readme for a given page was set to a
filesystem file. The following request would return my /etc/passwd file:
http://git.zx2c4.com/?url=/somerepo/about/../../../../etc/passwd
http://data.zx2c4.com/cgit-directory-traversal.png
This fix uses realpath(3) to canonicalize all paths, and then compares
the base components.
This fix introduces a subtle timing attack, whereby a client can check
whether or not strstr is called using timing measurements in order
to determine if a given file exists on the filesystem.
This fix also does not account for filesystem race conditions (TOCTOU)
in resolving symlinks.

When building the "test" target we depend on both cgit and building the
Git tools. By doing this with two targets we end up running make in the
git/ directory twice, concurrently if using parallel make, which causes
us to build more than we need and potentially builds incorrectly if
multi-step build-then-move operations overlap.
Fix this by instead calling back into the makefile so that we alter the
"cgit" target to also build the Git tools.

When creating the GIT-VERSION-FILE that we use to test that the version
of Git in git/ is the same as in the CGit Makefile, Git applies the
transform "s/-/./g" to the version string. This doesn't affect released
versions but does change RC version numbers such as 1.8.3-rc0.
While CGit should only refer to a released Git version in general, it is
useful to developers who want to test upcoming Git releases if the tests
do work with RCs, so change t0001 to apply the same transform to our
Makefile version before comparing it to the contents of
GIT-VERSION-FILE.

Commit fb3655d (use struct strbuf instead of static buffers -
2013-04-06) introduced a regression in the "section-from-path" handling
when the configured value is negative. By changing the "rel" variable
so that it includes a trailing slash, counting slashes from the end of
the string no longer gives the same answer as it did before.
Fix this by ensuring that "rel" does not have a trailing slash.

When testing modifications in Git that affect CGit, it is annoying to
have t0001 failing simply because the Git version has a ".dirty" suffix
when the version of Git there does indeed match that specified in the
CGit makefile. Stop this by stripping the ".dirty" suffix from the
GIT_VERSION variable.
Note that this brings the "Git version" behaviour in line with the
"submodule version" case which does not check if the working tree in
git/ is modified.

By default, Git's test suite puts the trash directories and test-results
directory into its own directory, not that containing the tests being
run. This is less convenient for inspecting test failures, so set the
output directory to CGit's tests/ directory instead.
Note that there is currently a bug in Git whereby it will create the
trash directories in our tests/ directory regardless of the value of
TEST_OUTPUT_DIRECTORY, and then fail to remove them once the tests are
done. This change does currently affect the location of the
test-results/ directory though.

Use "struct strbuf" from Git to remove the limit on file path length.
Notes on scan-tree:
This is slightly involved since I decided to pass the strbuf into
add_repo() and modify if whenever a new file name is required, which
should avoid any extra allocations within that function. The pattern
there is to append the filename, use it and then reset the buffer to its
original length (retaining a trailing '/').
Notes on ui-snapshot:
Since write_archive modifies the argv array passed to it we
copy the argv_array values into a new array of char* and then free the
original argv_array structure and the new array without worrying about
what the values now look like.

The CGit configuration variable virtual_root is normalized so that it
does not have a trailing '/' character, but it is allowed to be empty
(the empty string and NULL have different meanings here) and there is
code that is insufficiently cautious when checking if it ends in a '/':
if (virtual_root[strlen(virtual_root) - 1] != '/')
Clearly this check is redundant, but rather than simply removing it we
get a slight efficiency improvement by switching the normalization so
that the virtual_root variable always ends in '/'. Do this with a new
"ensure_end" helper.

It is common practice and semantically appropriate to use unordered
lists for long navigation lists.
This also fixes the layout of very long pager navigations in
Webkit-based browsers.

There's no need for this variable to be global. Printing the header in
print_urls() instead of print_url() allows for moving this variable into
print_urls() without having to pass any status to print_url().
Note that this only works as long as we don't call print_urls() more
than once.

This squelches a gcc warning. It's also correct that we check to see if
there are any partial or failed writes. For now, we just print a warning
to stderr. In the future, perhaps it will prove wise to exit(1) on
partial writes.

Since tail is initialized to 0, we will never get a warning on the last
if statement, but recent gcc complains anyway. So, we initialize len as
well. Future gcc versions should be able to optimize this out anyway.

On some platforms (notably Solaris) /bin/sh doesn't support enough of
POSIX for gen-version.sh to run. Git's Makefile provides SHELL_PATH_SQ
to address this issue so we just have to use it.

If CGIT_VERSION is in CGIT_CFLAGS then a change in version (for example
because you have committed your changes) causes all of the CGit objects
to be rebuilt. Avoid this by using EXTRA_CPPFLAGS to add the version
for only those files that are affected and make them depend on VERSION.

We already have a global cgit_version which is set from the #define'd
CGIT_VERSION in cgit.c. Change ui-patch.c to use this so that we only
need to rebuild cgit.o when the version changes.

Git does quite a lot of platform-specific detection in its Makefile,
which can result in it defining preprocessor variables that are used in
its header files. If CGit does not define the same variables it can
result in different sizes of some structures in different places in the
same application.
For example, on Solaris Git uses it's "compat" regex library which has a
different sized regex_t structure than that available in the platform
regex.h. This has a knock-on effect on the size of "struct rev_info"
and leads to hard to diagnose runtime issues.
In order to avoid all of this, introduce a "cgit.mk" file that includes
Git's Makefile and make all of the existing logic apply to CGit's
objects as well. This is slightly complicated because Git's Makefile
must run in Git's directory, so all references to CGit files need to be
prefixed with "../".
In addition, OBJECTS is a simply expanded variable in Git's Makefile so
we cannot just add our objects to it. Instead we must copy the two
applicable rules into "cgit.mk". This has the advantage that we can
split CGit-specific CFLAGS from Git's CFLAGS and hence avoid rebuilding
all of Git whenever a CGit-specific value changes.

This ensures that the Git version pointed at by the submodule is the
same as the one that will be fetched using "make get-git".
