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;
}

I have a number of repositories that start tagging with just '1' and
count up. Actually references with sting length of one are skipped, this
patch changes that.
If time-to-live is set to zero, we don't need to regenerate the cache
slots on every request. Instead, just skip the caching process and
immediately provide the dynamically generated version of the page.
Setting time-to-live to zero is useful when you want to disable caching
for certain pages.

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
snapshot cache slots) is caching of snapshots while disabling the cache
for static/dynamic HTML pages (by setting TTL to zero for everything
except for snapshot requests).

Right now if you visit:
<http://git.zx2c4.com/systemd/diff/src/udev/udev-builtin-input_id.c?id=bcfce235>
you'll see that if you reload the page a few times, a bunch of times the
diffstat comes out with no lines being shown or changed. I'm not
currently sure what the cause of this is, but I suspect it might have to
do with this uninitialized data.

Some people may clone the cgit repository and compile within a sandbox
or on another machine where git is not necessarily installed. When it
happens, cgit is getting compiled with an empty version number.
This commit fixes this.
This breaks compat with the previous LUA_IMPLEMENTATION but gives more
flexibility in that user can specify the pkg-config package name
directly.

sendfile() does the same job and avoids to copy the content into userland
and back. One has to define NO_SENDFILE in case the OS (kernel / libc)
does not supported. It is disabled by default on non-linux environemnts.
According to the glibc, sendfile64() was added in Linux 2.4 (so it has
been there for a while) but after browsing over the mapage of FreeBSD's I
noticed that the prototype is little different.

Drop the context parameter from the following functions (and all static
helpers used by them) and use the global context instead:
* cgit_print_http_headers()
* cgit_print_docstart()
* cgit_print_pageheader()
Remove context parameter from all commands
Drop the context parameter from the following functions (and all static
helpers used by them) and use the global context instead:
* cgit_get_cmd()
* All cgit command functions.
* cgit_clone_info()
* cgit_clone_objects()
* cgit_clone_head()
* cgit_print_plain()
* cgit_show_stats()
In initialization routines, use the global context variable instead of
passing a pointer around locally.
Remove callback data parameter for cache slots
This is no longer needed since the context is always read from the
global context variable.

This leverages the new lua support. See
filters/simple-authentication.lua for explaination of how this works.
There is also additional documentation in cgitrc.5.txt.
Though this is a cookie-based approach, cgit's caching mechanism is
preserved for authenticated pages.
Very plugable and extendable depending on user needs.
The sample script uses an HMAC-SHA1 based cookie to store the
currently logged in user, with an expiration date.

* Validate the email filter by manipulating stdin. Additional checks for
all the arguments can be added in a later patch.
* Add the exec prefix to all informational messages.
* Rename the filter repository to filter-exec. The Git repository itself
is not renamed since it can be shared amongst all filter types.
* In the filter checks, check whether all arguments are passed properly
instead of validating the buffer/stdin only.

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
message depending on what happens.
Also, we do not link against libdl on the BSDs, since they include it as
part of libc.

So that we don't have to include the if(filter) open_filter(filter)
block everywhere, we introduce the guard in the function itself. This
