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.

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.

Move chmod(foo, 0444) into move_temp_to_file()

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.

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.

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.

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 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

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

The program flow of pushing over http is:

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 is because openssl header files are always included in

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

As suggested by Jeff King, the best solution is to rename our references

An earlier commit aa1dbc9 (Update http-push functionality, 2006-03-07)
borrowed some code from rev-list.c.
This copy and paste made sense back then, because mark_edges_uninteresting(),
and its helper mark_edge_parents_uninteresting(), accessed a file scope
static variable "revs" in rev-list.c, and http-push.c did not have nor care
about such a variable.
But these days they are already properly libified and live in list-objects.c
and they take "revs" as as an argument. Make use of them and lose 20 or
so lines.

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).

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

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]

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).

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).

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.

Existing "git push --all" is almost perfect for backing up to
another repository, except that "--all" only means "all
branches" in modern git, and it does not delete old branches and
tags that exist at the back-up repository that you have removed
from your local repository.
This teaches "git-send-pack" a new "--mirror" option. The
difference from the "--all" option are that (1) it sends all
refs, not just branches, and (2) it deletes old refs you no
longer have on the local side from the remote side.

traditional list users, who want the list-like format, and who don't
actually use or want the name. And another class of users that really used
the list as an extensible array, and generally wanted to name the objects.
The patch is fairly straightforward, but it's also biggish. Most of it
really just cleans things up: switching the revision parsing and listing
over to the array makes things like the builtin-diff usage much simpler
(we now see exactly how many members the array has, and we don't get the
objects reversed from the order they were on the command line).
One of the main reasons for doing this at all is that the malloc overhead
of the simple object list was actually pretty high, and the array is just
a lot denser. So this patch brings down memory usage by git-rev-list by
just under 3% (on top of all the other memory use optimizations) on the
mozilla archive.
It does add more lines than it removes, and more importantly, it adds a
whole new infrastructure for maintaining lists of objects, but on the
other hand, the new dynamic array code is pretty obvious. The change to
builtin-diff-tree.c shows a fairly good example of why an array interface
is sometimes more natural, and just much simpler for everybody.

This shrinks "struct object" by a small amount, by getting rid of the
"struct type *" pointer and replacing it with a 3-bit bitfield instead.
In addition, we merge the bitfields and the "flags" field, which
incidentally should also remove a useless 4-byte padding from the object
when in 64-bit mode.
Now, our "struct object" is still too damn large, but it's now less
obviously bloated, and of the remaining fields, only the "util" (which is
not used by most things) is clearly something that should be eventually
discarded.
This shrinks the "git-rev-list --all" memory use by about 2.5% on the
kernel archive (and, perhaps more importantly, on the larger mozilla
archive). That may not sound like much, but I suspect it's more on a
64-bit platform.
There are other remaining inefficiencies (the parent lists, for example,
probably have horrible malloc overhead), but this was pretty obvious.
Most of the patch is just changing the comparison of the "type" pointer
from one of the constant string pointers to the appropriate new TYPE_xxx
small integer constant.

This adds a "tree_entry()" function that combines the common operation of
doing a "tree_entry_extract()" + "update_tree_entry()".
It also has a simplified calling convention, designed for simple loops
that traverse over a whole tree: the arguments are pointers to the tree
descriptor and a name_entry structure to fill in, and it returns a boolean
"true" if there was an entry left to be gotten in the tree.
This allows tree traversal with
struct tree_desc desc;
struct name_entry entry;
desc.buf = tree->buffer;
desc.size = tree->size;
while (tree_entry(&desc, &entry) {
... use "entry.{path, sha1, mode, pathlen}" ...
}
which is not only shorter than writing it out in full, it's hopefully less
error prone too.
[ It's actually a tad faster too - we don't need to recalculate the entry
pathlength in both extract and update, but need to do it only once.
Also, some callers can avoid doing a "strlen()" on the result, since
it's returned as part of the name_entry structure.
However, by now we're talking just 1% speedup on "git-rev-list --objects
--all", and we're definitely at the point where tree walking is no
longer the issue any more. ]
NOTE! Not everybody wants to use this new helper function, since some of
the tree walkers very much on purpose do the descriptor update separately
from the entry extraction. So the "extract + update" sequence still
remains as the core sequence, this is just a simplified interface.
We should probably add a silly two-line inline helper function for
initializing the descriptor from the "struct tree" too, just to cut down
on the noise from that common "desc" initializer.

Instead, just use the tree buffer directly, and use the tree-walk
infrastructure to walk the buffers instead of the tree-entry list.
The tree-entry list is inefficient, and generates tons of small
allocations for no good reason. The tree-walk infrastructure is
generally no harder to use than following a linked list, and allows
us to do most tree parsing in-place.
Some programs still use the old tree-entry lists, and are a bit
painful to convert without major surgery. For them we have a helper
function that creates a temporary tree-entry list on demand.

Merging all three option parsers related to whatchanged is
unarguably the right thing, but the fallout was too big to scare
me away. Let's try it once again, but once step at time.
This splits out init_revisions() call from setup_revisions(), so
that the callers can set different defaults to match the

The parent rewriting feature caused us to create the whole history in one
go, and then simplify it later, because of how rewrite_parents() had been
written. However, with a little tweaking, it's perfectly possible to do
even that one incrementally.
Right now, this doesn't really much matter, because every user of
"--parents" will probably generally _also_ use "--topo-order", which will
cause the old non-incremental behaviour anyway. However, I'm hopeful that
we could make even the topological sort incremental, or at least
_partially_ so (for example, make it incremental up to the first merge).
In the meantime, this at least moves things in the right direction, and
removes a strange special case.

This brings http-push functionality more in line with the ssh/git version,
by borrowing bits from send-pack and rev-list to process refspecs and

is determined using PROPFIND requests for the object directory rather than
HEAD requests for each object - while it may be less efficient for small
numbers of objects, this approach is able to get the status of all remote
loose objects in a maximum of 256 requests.
