Instead of using our own formatting, use log_tree_commit() from Git to
create patches. This removes unnecessary duplicate code and also fixes a

Sync with what we do everywhere else and check the return value of
get_sha1() instead of calling sha1_object_info() to validate the object.
Note that we later call lookup_commit_reference(), which checks that
both SHA1 values refer to commits, anyway.

Move filepair_cb() from ui-patch.c to ui-shared.c and rename it to
filepair_cb_raw(). This callback will be used in ui-diff.c in a
follow-up patch.
Note that it is not straightforward to extract filepair_cb() from
ui-diff.c which is why it is not done here as well.

When having found the first path separator occurrence at position i, we
invoked strchr() on the same position i in subsequent iterations
resulting in the same path separator being returned by strchr() over and
over again. Increase the position by one to skip the occurrence that has
just been found and advance to the next separator.

Use struct strbuf from Git instead of fixed-size buffers to remove the

We've long supported negative ttls, for infinite cache, except the
documentation incorrectly showed one of our defaults as being 5 and not
-1. As well, with a negative ttl, we were actually making the HTTP
expired header go backwards. This changes it to go ahead ten years
instead.
Further, we add an cache-about-ttl option to set a different ttl for
about pages, which are now increasingly being filtered through markdown
or just sent statically anyway.

My dmesg is filled with the oom killer bringing down processes while the
Bingbot downloads every snapshot for every commit of the Linux kernel in

wasting resources like that in the first place.

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.
- more robust test suite.
- more rebust makefile dependency accounting.
- 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.
- "about-filter" now receives the filename being filtered as argv[1]. This may
disrupt existing scripts, so adjust accordingly.
- gitconfig and gitattributes are no longer loaded from any system directories
or home directories.
Security:
- CVE-2013-2117: disallow directory traversal when readme is set to filesystem
path.
Bug fixes:
- ssdiff now correctly manages tab expansion.
- support unannotated tags in http git clone.
- lots of cleanups of global variables and memory leaks.
- do not rely on gettext/libintl.
- better C standard compliance.
- make several functions and variables static.
- improved constification.
- remove unused functions.
- fix colspan values to correct width.
- fix out-of-bounds memory accesses with virtual_root="".
- cache repo config more precisely.
- die when write fails.

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/passwdhttp://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.

The readme variable may now contain multiple space deliminated entries,
which per usual are either a filepath or a git ref filepath. If multiple
are specified, cgit will now select the first one in the list that
exists. This is to make it easier to specify multiple default readme
types in the main cgitrc file and have them automatically get applied to
each repo based on what exists.

The number of odd cases in which git will try to read config is far too

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.
