The current code works like this: if others flags than POLLIN is
raised we assume that (a) something bad happened and the child died or
(b) the child has closed the pipe because it had no more data to send.
For the latter case, we assume wrongly that one call to
process_input() will empty the pipe. Indeed it reads only 16Ko of data
by call and the the pipe capacity can be larger than that (on current
Linux kernel, it is 65536 bytes). Therefore the child can write 32ko
of data, for example, and close the pipe. After that poll will return
POLLIN _and_ POLLHUP and the parent will read only 16ko of data.
This patch forces the parent to empty the pipe as soon as POLLIN is
raised and even if POLLHUP or something else is raised too.
Moreover, some implementations of poll might return POLLRDNORM flag
even if it is non standard.

This patch removes the custom tree walker tree_traverse(), and makes
generate_tar() use write_tar_archive() and the infrastructure provided
by git-archive instead.
As a kind of side effect, make write_tar_archive() able to handle NULL
as base directory, as this is what the new and simple generate_tar()
uses to indicate the absence of a base directory. This was simpler
and cleaner than playing tricks with empty strings.
The behaviour of git-tar-tree should be unchanged (quick tests didn't
indicate otherwise) except for the text of some error messages.

Now three types of path based URLs are supported:
gitweb.cgi/project.git
gitweb.cgi/project.git/branch
gitweb.cgi/project.git/branch/filename
The first one (show project summary) was already supported for a long time
now. The other two are new: they show the shortlog of a branch or
the plain file contents of some file contained in the repository.
This is especially useful to support project web pages for small
projects: just create an html branch and then use an URL like
gitweb.cgi/project.git/html/index.html.

In "git-apply", we have a few sanity checks and heuristics that
expects that the patch fed to us is a unified diff with at least
one line of context.
* When there is no leading context line in a hunk, the hunk
must apply at the beginning of the preimage. Similarly, no
trailing context means that the hunk is anchored at the end.
* We learn a patch deletes the file from a hunk that has no
resulting line (i.e. all lines are prefixed with '-') if it
has not otherwise been known if the patch deletes the file.
Similarly, no old line means the file is being created.
And we declare an error condition when the file created by a
creation patch already exists, and/or when a deletion patch
still leaves content in the file.
These sanity checks are good safety measures, but breaks down
when people feed a diff generated with --unified=0. This was
recently noticed first by Matthew Wilcox and Gerrit Pape.
This adds a new flag, --unified-zero, to allow bypassing these
checks. If you are in control of the patch generation process,
you should not use --unified=0 patch and fix it up with this
flag; rather you should try work with a patch with context. But
if all you have to work with is a patch without context, this
flag may come handy as the last resort.

I had a hard time figuring out why this test was failing with
the packed-refs update without running it under "sh -x". This
makes output from "sh t1400-update-ref.sh -v" more descriptive.
Updating other tests would be a good janitorial task.

This allows you to maintain a few filesystem pathnames concurrently, by
simply replacing the single static "pathname" buffer with a LRU of four
buffers.
We did exactly the same thing with sha1_to_hex(), for pretty much exactly
the same reason. Sometimes you want to use two pathnames, and while it's
easy enough to xstrdup() them, why not just do the LU buffer thing.

Make it possible to use href() subroutine to generate link with
query string which does not include project ('p') parameter.
href() used to add project=$project to its parameters, if it
was not set (to be more exact if $params{'project'} was false).
Now you can pass "project => undef" if you don't want for href()
to add project parameter to query string in the generated link.
Links to "project_list", "project_index" and "opml" (all related
to list of all projects/all git repositories) doesn't need project
parameter. Moreover "project_list" is default view (action) if
project ('p') parameter is not set, just like "summary" is default
view (action) if project is set; project list served as a kind
of "home" page for gitweb instalation, and links to "project_list"
view were done without specyfying it as an action.
Convert remaining links (except $home_link and anchor links)
to use href(); this required adding 'order => "o"' to @mapping
in href(). This finishes consolidation of URL generation.

Add git_project_index, which generates index.aux file that can be used
as a source of projects list, instead of generating projects list from
a directory. Using file as a source of projects list allows for some
projects to be not present in gitweb main (project_list) page, and/or
correct project owner info. And is probably faster.
Additionally it can be used to get the list of all available repositories
for scripts (in easily parseable form).

This is in response to Linus's work on packed refs. Additionally it
makes gitweb work with symrefs, too.
Do not parse refs by hand, using File::Find and reading individual
heads to get hash of reference, but use git-peek-remote output
instead. Assume that the hash for deref (with ^{}) always follows hash
for ref, and that we have derefs only for tag objects; this removes
call to git_get_type (and git-cat-file -t invocation) for tags, which
speeds "summary" and "tags" views generation, but might slow generation
of "heads" view a bit. For now, we do not save and use the deref hash.
Remove git_get_hash_by_ref while at it, as git_get_refs_list was the
only place it was used.

It turns out that I actually wanted to avoid the filenames (because I
didn't care - I just wanted to see the context in which something was
used) when doing a grep. But since "git grep" didn't take the "-h"
parameter, I ended up having to do "grep -5 -h *.c" instead.
So here's a trivial patch that adds "-h" (and thus has to enable -H too)
to "git grep" parsing.

Fetch over http from a repository that uses alternates to borrow
from neighbouring repositories were quite broken, apparently for
some time now.
We parse input and count bytes to allocate the new buffer, and
when we copy into that buffer we know exactly how many bytes we
want to copy from where. Using strlcpy for it was simply
stupid, and the code forgot to take it into account that strlcpy
terminated the string with NUL.

Franck noticed that the code around polling and relaying messages
from the child process was quite bogus. Here is an attempt to
clean it up a bit, based on his patch:
- When POLLHUP is set, it goes ahead and reads the file
descriptor. Worse yet, it does not check the return value of
read() for errors when it does.
- When we processed one POLLIN, we should just go back and see
if any more data is available. We can check if the child is
still there when poll gave control back at us but without any
actual input.
[jc: with simplification suggested by Franck. ]

git_connect() can return 0 if we use git protocol for example.
Users of this function don't know and don't care if a process
had been created or not, and to avoid them to check it before
calling finish_connect() this patch allows finish_connect() to
take a null pid. And in that case return 0.
