Shawn O. Pearce	de1a2fdd38	Smart push over HTTP: client side The git-remote-curl backend detects if the remote server supports the git-receive-pack service, and if so, runs git-send-pack in a pipe to dump the command and pack data as a single POST request. The advertisements from the server that were obtained during the discovery are passed into git-send-pack before the POST request starts. This permits git-send-pack to operate largely unmodified. For smaller packs (those under 1 MiB) a HTTP/1.0 POST with a Content-Length is used, permitting interaction with any server. The 1 MiB limit is arbitrary, but is sufficent to fit most deltas created by human authors against text sources with the occasional small binary file (e.g. few KiB icon image). The configuration option http.postBuffer can be used to increase (or shink) this buffer if the default is not sufficient. For larger packs which cannot be spooled entirely into the helper's memory space (due to http.postBuffer being too small), the POST request requires HTTP/1.1 and sets "Transfer-Encoding: chunked". This permits the client to upload an unknown amount of data in one HTTP transaction without needing to pregenerate the entire pack file locally. Signed-off-by: Shawn O.

Shawn O. Pearce	97cc7bc45c	Discover refs via smart HTTP server when available Instead of loading the cached info/refs, try to use the smart HTTP version when the server supports it. Since the smart variant is actually the pkt-line stream from the start of either upload-pack or receive-pack we need to parse these through get_remote_heads, which requires a background thread to feed its pipe.

Shawn O. Pearce	b8538603a3	Smart HTTP fetch: gzip requests The upload-pack requests are mostly plain text and they compress rather well. Deflating them with Content-Encoding: gzip can easily drop the size of the request by 50%, reducing the amount of data to transfer as we negotiate the common commits. Signed-off-by: Shawn O.

Daniel Barkalow	a45d3d7eff	Allow curl helper to work without a local repository It's okay to use the curl helper without a local repository, so long as you don't use "fetch". There aren't any git programs that would try to use it, and it doesn't make sense to try it (since there's nowhere to write the results), but we may as well be clear.

Shawn O. Pearce	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.

Shawn O. Pearce	ef08ef9ea0	remote-helpers: Support custom transport options Some transports, like the native pack transport implemented by fetch-pack, support useful features like depth or include tags. These should be exposed if the underlying helper knows how to use them. Signed-off-by: Shawn O.

Shawn O. Pearce	292ce46b60	remote-helpers: Fetch more than one ref in a batch Some network protocols (e.g. native git://) are able to fetch more than one ref at a time and reduce the overall transfer cost by combining the requests into a single exchange. Instead of feeding each fetch request one at a time to the helper, feed all of them at once so the helper can decide whether or not it should batch them. Signed-off-by: Shawn O.

Shawn O. Pearce	37a8768f83	remote-curl: Refactor walker initialization We will need the walker, url and remote in other functions as the code grows larger to support smart HTTP. Extract this out into a set of globals we can easily reference once configured. Signed-off-by: Shawn O.

Björn Steinbrink	d01a8e32fe	clone: Supply the right commit hash to post-checkout when -b is used When we use -b <branch>, we may checkout something else than what the remote's HEAD references, but we still used remote_head to supply the new ref value to the post-checkout hook, which is wrong. So instead of using remote_head to find the value to be passed to the post-checkout hook, we have to use our_head_points_at, which is always correctly setup, even if -b is not used. This also fixes a segfault when "clone -b <branch>" is used with a remote repo that doesn't have a valid HEAD, as in such a case remote_head is NULL, but we still tried to access it.

Johannes Sixt	c6dfb39944	remote-curl: add missing initialization of argv0_path All programs, in particular also the stand-alone programs (non-builtins) must call git_extract_argv0_path(argv[0]) in order to help builds that derive the installation prefix at runtime, such as the MinGW build. Without this call, the program segfaults (or raises an assertion failure).
