d21f9794ce Disable CURLOPT_NOBODY before enabling CURLOPT_PUT and CURLOPT_POST
This works around a bug in curl versions up to 7.19.4, where disabling the
CURLOPT_NOBODY option sets the internal state incorrectly considering that
CURLOPT_PUT was enabled earlier.

The bug is discussed at http://curl.haxx.se/bug/view.cgi?id=2727981 and is
corrected in the latest version of curl in CVS.

This bug usually has no impact on git, but may surface if using multi-pass
authentication methods.

548d3464dc Show usage string for 'git http-push -h'
http-push already knows how to dump usage if it is given no options, but
it interprets '-h' as the URL to a remote repository:

    $ git http-push -h
    error: Cannot access URL -h/, return code 6

Dump usage instead.  Humans wanting to pass the URL -h/ to curl for some
reason can use 'git http-push -h/' explicitly.  Scripts expecting to
access an HTTP repository at URL '-h' will break, though.

Also delay finding a git directory until after option parsing, so
"http-push -h" can be used outside any git repository.

ae4efe1957 Move WebDAV HTTP push under remote-curl
The remote helper interface now supports the push capability,
which can be used to ask the implementation to push one or more
specs to the remote repository.  For remote-curl we implement this
by calling the existing WebDAV based git-http-push executable.

Internally the helper interface uses the push_refs transport hook
so that the complexity of the refspec parsing and matching can be
reused between remote implementations.  When possible however the
helper protocol uses source ref name rather than the source SHA-1,
thereby allowing the helper to access this name if it is useful.

>From Clemens Buchacher <drizzd@aon.at>:
 update http tests according to remote-curl capabilities

 o Pushing packed refs is now fixed.

 o The transport helper fails if refs are already up-to-date. Add
   a test for that.

 o The transport helper will notice if refs are already
   up-to-date. We therefore need to update server info in the
   unpacked-refs test.

 o The transport helper will purge deleted branches automatically.

 o Use a variable ($ORIG_HEAD) instead of full SHA-1 name.

2af202be3d Fix various sparse warnings in the git source code
There are a few remaining ones, but this fixes the trivial ones. It boils
down to two main issues that sparse complains about:

 - warning: Using plain integer as NULL pointer

   Sparse doesn't like you using '0' instead of 'NULL'. For various good
   reasons, not the least of which is just the visual confusion. A NULL
   pointer is not an integer, and that whole "0 works as NULL" is a
   historical accident and not very pretty.

   A few of these remain: zlib is a total mess, and Z_NULL is just a 0.
   I didn't touch those.

 - warning: symbol 'xyz' was not declared. Should it be static?

   Sparse wants to see declarations for any functions you export. A lack
   of a declaration tends to mean that you should either add one, or you
   should mark the function 'static' to show that it's in file scope.

   A few of these remain: I only did the ones that should obviously just
   be made static.

That 'wt_status_submodule_summary' one is debatable. It has a few related
flags (like 'wt_status_use_color') which _are_ declared, and are used by
builtin-commit.c. So maybe we'd like to export it at some point, but it's
not declared now, and not used outside of that file, so 'static' it is in
this patch.

5424bc557f http*: add helper methods for fetching objects (loose)
The code handling the fetching of loose objects in http-push.c and
http-walker.c have been refactored into new methods and a new struct
(object_http_request) in http.c. They are not meant to be invoked
elsewhere.

The new methods in http.c are
 - new_http_object_request
 - process_http_object_request
 - finish_http_object_request
 - abort_http_object_request
 - release_http_object_request

and the new struct is http_object_request.

RANGER_HEADER_SIZE and no_pragma_header is no longer made available
outside of http.c, since after the above changes, there are no other
instances of usage outside of http.c.

Remove members of the transfer_request struct in http-push.c and
http-walker.c, including filename, real_sha1 and zret, as they are used
no longer used.

Move the methods append_remote_object_url() and get_remote_object_url()
from http-push.c to http.c. Additionally, get_remote_object_url() is no
longer defined only when USE_CURL_MULTI is defined, since
non-USE_CURL_MULTI code in http.c uses it (namely, in
new_http_object_request()).

Refactor code from http-push.c::start_fetch_loose() and
http-walker.c::start_object_fetch_request() that deals with the details
of coming up with the filename to store the retrieved object, resuming
a previously aborted request, and making a new curl request, into a new
function, new_http_object_request().

Refactor code from http-walker.c::process_object_request() into the
function, process_http_object_request().

Refactor code from http-push.c::finish_request() and
http-walker.c::finish_object_request() into a new function,
finish_http_object_request(). It returns the result of the
move_temp_to_file() invocation.

Add a function, release_http_object_request(), which cleans up object
request data. http-push.c and http-walker.c invoke this function
separately; http-push.c::release_request() and
http-walker.c::release_object_request() do not invoke this function.

Add a function, abort_http_object_request(), which unlink()s the object
file and invokes release_http_object_request(). Update
http-walker.c::abort_object_request() to use this.

2264dfa5c4 http*: add helper methods for fetching packs
The code handling the fetching of packs in http-push.c and
http-walker.c have been refactored into new methods and a new struct
(http_pack_request) in http.c. They are not meant to be invoked
elsewhere.

The new methods in http.c are
 - new_http_pack_request
 - finish_http_pack_request
 - release_http_pack_request

and the new struct is http_pack_request.

Add a function, new_http_pack_request(), that deals with the details of
coming up with the filename to store the retrieved packfile, resuming a
previously aborted request, and making a new curl request. Update
http-push.c::start_fetch_packed() and http-walker.c::fetch_pack() to
use this.

Add a function, finish_http_pack_request(), that deals with renaming
the pack, advancing the pack list, and installing the pack. Update
http-push.c::finish_request() and http-walker.c::fetch_pack to use
this.

Update release_request() in http-push.c and http-walker.c to invoke
release_http_pack_request() to clean up pack request helper data.

The local_stream member of the transfer_request struct in http-push.c
has been removed, as the packfile pointer will be managed in the struct
http_pack_request.

b8caac2b8a http*: add http_get_info_packs
http-push.c and http-walker.c no longer have to use fetch_index or
setup_index; they simply need to use http_get_info_packs, a new http
method, in their fetch_indices implementations.

Move fetch_index() and rename to fetch_pack_index() in http.c; this
method is not meant to be used outside of http.c. It invokes
end_url_with_slash with base_url; apart from that change, the code is
identical.

Move setup_index() and rename to fetch_and_setup_pack_index() in
http.c; this method is not meant to be used outside of http.c.

Do not immediately set ret to 0 in http-walker.c::fetch_indices();
instead do it in the HTTP_MISSING_TARGET case, to make it clear that
the HTTP_OK and HTTP_MISSING_TARGET cases both return 0.

Create http_is_verbose. It is to be used by methods in http.c, and is
modified at the entry points of http.c's users, namely http-push.c
(when parsing options) and http-walker.c (in get_http_walker).

4f66250df6 http-push: send out fetch requests on queue
Previously, requests for remote files were simply added to the queue
(pointed to by request_queue_head) and no transfer actually takes
place (the fill function add_fill_function() is not added until line
2441), even though code that followed may rely on these remote files to
be present (eg. the setup_revisions invocation).

The code that sends out the requests on the request queue is refactored
into the method run_request_queue.

After the get_dav_remote_heads invocation (ie. after fetch requests are
added to the queue), the requests on the queue are sent out through an
invocation to run_request_queue.

This invocation to run_request_queue entails adding a fill function
before pushing checks take place, which may lead to accidental,
unwanted pushes previously.

The flag is_running_queue is introduced to prevent this from occurring.
fill_active_slot is made to check the flag is_running_queue before
the sending of the requests proceeds.

I used the following criteria when selecting the code for replacement:
- it was already printing a warning for the unlink failures
- it is in a function which already printing something or is
  called from such a function
- it is in a static function, returning void and the function is only

3944ba0cb0 Allow curl to rewind the read buffers
When using multi-pass authentication methods, the curl library may
need to rewind the read buffers (depending on how much already has
been fed to the server) used for providing data to HTTP PUT, POST or
PROPFIND, and in order to allow the library to do so, we need to tell
it how by providing either an ioctl callback or a seek callback.

This patch adds an ioctl callback, which should be usable on older
curl versions (since 7.12.3) than the seek callback (introduced in
curl 7.18.0).

Some HTTP servers (such as Apache) give an 401 error reply immediately
after receiving the headers (so no data has been read from the read
buffers, and thus no rewinding is needed), but other servers (such
as Lighttpd) only replies after the whole request has been sent and
all data has been read from the read buffers, making rewinding necessary.

This patch allows http_push to use http authentication via prompts.
You may notice that there is a remote struct that only contains the
url from the repo struct.  This struct is a temporary fix for a larger
issue, but gets http authentication via prompts out the door, and
keeps users from having to store passwords in plain text files.

dfab7c144e use a hash of the lock token as the suffix for PUT/MOVE
After 753bc91 ("Remove the requirement opaquelocktoken uri scheme"),
lock tokens are in the URI forms in which they are received from the
server, eg. 'opaquelocktoken:', 'urn:uuid:'.

However, "start_put" (and consequently "start_move"), which attempts to
create a unique temporary file using the UUID of the lock token,
inadvertently uses the lock token in its URI form. These file
operations on the server may not be successful (specifically, in
Windows), due to the colon ':' character from the URI form of the lock
token in the file path.

This patch uses a hash of the lock token instead, guaranteeing only
"safe" characters (a-f, 0-9) are used in the file path.

The token's hash is generated when the lock token is received from the
server in handle_new_lock_ctx, minimizing the number of times of
hashing.

b1c7d4aafe http-push: refactor lock-related headers creation for curl requests
DAV-related headers (more specifically, headers related to the lock token,
namely, If, Lock-Token, and Timeout) for curl requests are created and
allocated individually, eg a "if_header" variable for the "If: " header, a
"timeout_header" variable for the "Timeout: " header.

This patch provides a new function ("get_dav_token_headers") that creates
these header, saving methods from allocating memory, and from issuing a
"curl_slist_append()" call.  The temporary string storage given to
curl_slist_append() is freed much earlier than the previous code with this
patch, but this change is safe, because curl_slist_append() keeps a copy
of the given string.

In part, this patch also addresses the fact that commit 753bc91 (Remove
the requirement opaquelocktoken uri scheme) did not update memory
allocations for DAV-related headers.

57b235a4bc refactor signal handling for cleanup functions
The current code is very inconsistent about which signals
are caught for doing cleanup of temporary files and lock
files. Some callsites checked only SIGINT, while others
checked a variety of death-dealing signals.

This patch factors out those signals to a single function,
and then calls it everywhere. For some sites, that means
this is a simple clean up. For others, it is an improvement
in that they will now properly clean themselves up after a
larger variety of signals.

4a16d07272 chain kill signals for cleanup functions
If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:

  do_cleanup(); /* actual work */
  signal(signo, SIG_DFL); /* restore previous behavior */
  raise(signo); /* deliver signal, killing ourselves */

For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.

This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,
and use sigchain_pop to restore whoever was before you in
the stack.

466ddf90c2 http-push: when making directories, have a trailing slash in the path name
The function lock_remote() sends MKCOL requests to make leading
directories; However, if it does not put a forward slash '/' at the end of
the path, the server sends a 301 redirect.

By leaving the '/' in place, we can avoid this additional step.

Incidentally, at least one version of Curl (7.16.3) does not resend
credentials when it follows a 301 redirect, so this commit also fixes
a bug.

R. Tyler Ballance reported a mysterious transient repository corruption;
after much digging, it turns out that we were not catching and reporting
memory allocation errors from some calls we make to zlib.

This one _just_ wraps things; it doesn't do the "retry on low memory
error" part, at least not yet. It is an independent issue from the
reporting.  Some of the errors are expected and passed back to the caller,
but we die when zlib reports it failed to allocate memory for now.

e1f33efe07 http-push: support full URI in handle_remote_ls_ctx()
The program calls remote_ls() to get list of files from the server over
HTTP; handle_remote_ls_ctx() is used to parse its response to populate
"struct remote_ls_ctx" that is returned from remote_ls().

The handle_remote_ls_ctx() function assumed that the server returns a
local path in href field, but RFC 4918 (14.7) demand of support full URI
(e.g. "http://localhost:8080/repo.git").

This resulted in push failure (e.g. git-http-push issues a PROPFIND
request to "/repo.git/alhost:8080/repo.git/refs/" to the server).

753bc911f4 Remove the requirement opaquelocktoken uri scheme
The program flow of pushing over http is:

 - call lock_remote() to issue a DAV_LOCK request to the server to lock
   info/refs and branch refs being pushed into; handle_new_lock_ctx() is
   used to parse its response to populate "struct remote_lock" that is
   returned from lock_remote();

 - send objects;

 - call unlock_remote() to drop the lock.

The handle_new_lock_ctx() function assumed that the server will use a
lock token in opaquelocktoken URI scheme, which may have been an Ok
assumption under RFC 2518, but under RFC 4918 which obsoletes the older
standard it is not necessarily true.

This resulted in push failure (often resulted in "cannot lock existing
info/refs" error message) when talking to a server that does not use
opaquelocktoken URI scheme.

/usr/include/openssl/sha.h:117: error: previous declaration of 'SHA1_Final' was here
make: *** [fast-import.o] Error 1

This is because openssl header files are always included in
git-compat-util.h since commit 684ec6c63c whenever NO_OPENSSL is not
set, which somehow brings in <openssl/sha1.h> clashing with the custom
ARM version.  Compilation of git is probably broken on PPC too for the
same reason.

Turns out that the only file requiring openssl/ssl.h and openssl/err.h
is imap-send.c.  But only moving those problematic includes there
doesn't solve the issue as it also includes cache.h which brings in the
conflicting local SHA1 header file.

As suggested by Jeff King, the best solution is to rename our references
to SHA1 functions and structure to something git specific, and define those
according to the implementation used.

This simplifies a few things, makes a few things slightly more
complicated, but, more importantly, allows that, when struct ref can
represent a symref, http_fetch_ref() can return one.

Incidentally makes the string that http_fetch_ref() gets include "refs/"
(if appropriate), because that's how the name field of struct ref works.
As far as I can tell, the usage in walker:interpret_target() wouldn't have
worked previously, if it ever would have been used, which it wouldn't
(since the fetch process uses the hash instead of the name of the ref
there).

9fc6440d78 Set proxy override with http_init()
In transport.c, proxy setting (the one from the remote conf) was set through
curl_easy_setopt() call, while http.c already does the same with the
http.proxy setting. We now just use this infrastructure instead, and make
http_init() now take the struct remote as argument so that it can take the
http_proxy setting from there, and any other property that would be added
later.

At the same time, we make get_http_walker() take a struct remote argument
too, and pass it to http_init(), which makes remote defined proxy be used
for more than get_refs_via_curl().

We leave out http-fetch and http-push, which don't use remotes for the
moment, purposefully.

8e0f70033b Avoid unnecessary "if-before-free" tests.
This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:

        if (some_expression)
                free (some_expression);

with the now-equivalent:

        free (some_expression);

It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:

    http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html

FYI, the change below was prepared by running the following:

  git ls-files -z | xargs -0 \
  perl -0x3b -pi -e \
    's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'

Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }".  But that's ok, since there were none like
that in git sources.

Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code.  That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this

  if (x)
    free (x);
  else
    foo ();

into this:

  free (x);
  else
    foo ();

There were none of those here, either.

If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
 option to make it detect free-like functions with different names]

  http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free

Addendum:
  Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

without this patch, the lock is lifted before the last object for

325ce3959c http-push: clarify the reason of error from the initial PROPFIND request
The first thing http-push does is a PROPFIND to see if the other
end supports locking.  The failure message we give is always
reported as "no DAV locking support at the remote repository",
regardless of the reason why we ended up not finding the locking
support on the other end.

This moves the code to report "no DAV locking support" down the
codepath so that the message is issued only when we successfully
get a response to PROPFIND and the other end say it does not
support locking.  Other failures, such as connectivity glitches
and credential mismatches, have their own error message issued
and we will not issue "no DAV locking" error (we do not even
know if the remote end supports it).

9bdbabade4 http-push: fail when info/refs exists and is already locked
Failing instead of silently not updating remote refs makes the things
clearer for the user when trying to push on a repository while another
person do (or while a dandling locks are waiting for a 10 minutes
timeout).

When silently not updating remote refs, the user does not even know
that git has pushed the objects but leaved the refs as they were
before (e.g. a new bunch of commits on branch "master" is uploaded,
however the branch by itsel still points on the previous head commit).

9116de5957 http-push: fix webdav lock leak.
Releasing webdav lock even if push fails because of bad (or no)
reference on command line.

To reproduce the issue that this patch fixes, prepare a test repository
availlable over http+webdav, say at http://myhost/myrepo.git/

Then:

  $ git clone http://myhost/myrepo.git/
  $ cd myrepo
  $ git push http
  Fetching remote heads...
    refs/
    refs/heads/
    refs/tags/
  No refs in common and none specified; doing nothing.
  $ git push http
  Fetching remote heads...
    refs/
    refs/heads/
    refs/tags/
  No refs in common and none specified; doing nothing.
  $

Finally, you look at the web server logs, and will find one LOCK query
and no UNLOCK query, of course the second one will be in 423 return
code instead of 200:

1.2.3.4 - gb [19/Jan/2008:14:24:56 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 200 465
(...)
1.2.3.4 - gb [19/Jan/2008:14:25:10 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 423 363

With this patch, there would have be two UNLOCKs in addition of the LOCKs

From the user's point of view:

- If you realize that you should have typed e.g. "git push http
  master" instead of "git push http", you will have to wait for 10
  minutes for the lock to expire by its own.

- Furthermore, if somebody else is dumb enough to type "git push http"
  while you need to push "master" branch, then you'll need too to wait
  for 10 minutes too.
