* Smart fetch over HTTP: client sideShawn O. Pearce2009-11-041-17/+93
| | | | | | | | | | | | | | | | | | | | | | | | | The git-remote-curl backend detects if the remote server supports the git-upload-pack service, and if so, runs git-fetch-pack locally in a pipe to generate the want/have commands. The advertisements from the server that were obtained during the discovery are passed into git-fetch-pack before the POST request starts, permitting server capability discovery and enablement. Common objects that are discovered are appended onto the request as have lines and are sent again on the next request. This allows the remote side to reinitialize its in-memory list of common objects during the next request. Because all requests are relatively short, below git-remote-curl's 1 MiB buffer limit, requests will use the standard Content-Length header and be valid HTTP/1.0 POST requests. This makes the fetch client more tolerant of proxy servers which don't support HTTP/1.1 or the chunked transfer encoding. Signed-off-by: Shawn O.

* Add multi_ack_detailed capability to fetch-pack/upload-packShawn O. Pearce2009-10-301-9/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When multi_ack_detailed is enabled the ACK continue messages returned by the remote upload-pack are broken out to describe the different states within the peer. This permits the client to better understand the server's in-memory state. The fetch-pack/upload-pack protocol now looks like: NAK --------------------------------- Always sent in response to "done" if there was no common base selected from the "have" lines (or no have lines were sent). * no multi_ack or multi_ack_detailed: Sent when the client has sent a pkt-line flush ("0000") and the server has not yet found a common base object. * either multi_ack or multi_ack_detailed: Always sent in response to a pkt-line flush. ACK %s ----------------------------------- * no multi_ack or multi_ack_detailed: Sent in response to "have" when the object exists on the remote side and is therefore an object in common between the peers. The argument is the SHA-1 of the common object. * either multi_ack or multi_ack_detailed: Sent in response to "done" if there are common objects. The argument is the last SHA-1 determined to be common. ACK %s continue ----------------------------------- * multi_ack only: Sent in response to "have". The remote side wants the client to consider this object as common, and immediately stop transmitting additional "have" lines for objects that are reachable from it. The reason the client should stop is not given, but is one of the two cases below available under multi_ack_detailed. ACK %s common ----------------------------------- * multi_ack_detailed only: Sent in response to "have". Both sides have this object. Like with "ACK %s continue" above the client should stop sending have lines reachable for objects from the argument. ACK %s ready ----------------------------------- * multi_ack_detailed only: Sent in response to "have". The client should stop transmitting objects which are reachable from the argument, and send "done" soon to get the objects. If the remote side has the specified object, it should first send an "ACK %s common" message prior to sending "ACK %s ready". Clients may still submit additional "have" lines if there are more side branches for the client to explore that might be added to the common set and reduce the number of objects to transfer.

* Move "get_ack()" back to fetch-packShawn O. Pearce2009-10-301-0/+21
| | | | | | | | | | | | In 41cb7488 Linus moved this function to connect.c for reuse inside of the git-clone-pack command. That was 2005, but in 2006 Junio retired git-clone-pack in commit efc7fa53. Since then the only caller has been fetch-pack. Since this ACK/NAK exchange is only used by the fetch-pack/upload-pack protocol we should move it back to be a private detail of fetch-pack.

* fetch-pack: Use a strbuf to compose the want listShawn O. Pearce2009-10-301-18/+34
| | | | | | | | | | | | | | | | | This change is being offered as a refactoring to make later commits in the smart HTTP series easier. By changing the enabled capabilities to be formatted in a strbuf it is easier to add a new capability to the set of supported capabilities. By formatting the want portion of the request into a strbuf and writing it as a whole block we can later decide to hold onto the req_buf (instead of releasing it) to recycle in stateless communications.

* fetch-pack: close output channel after sideband demultiplexer terminatesJohannes Sixt2009-06-081-1/+3
| | | | | | | | | | | | | | | | | | | | | fetch-pack runs the sideband demultiplexer using start_async(). This facility requires that the asynchronously executed function closes the output file descriptor (see Documentation/technical/api-run-command.txt). But the sideband demultiplexer did not do that. This fixes it. In certain error situations this could lock up a fetch operation on Windows because the asynchronous function is run in a thread; by not closing the output fd the reading end never got EOF and waited for more data indefinitely. On Unix this is not a problem because the asynchronous function is run in a separate process, which exits after the function ends and so implicitly closes the output. Since the pack that is sent over the wire encodes the number of objects in the stream, during normal operation the reading end knows when the stream ends and terminates by itself, and does not lock up.

| * | Record ns-timestamps if possible, but do not use it without USE_NSECKjetil Barvik2009-03-071-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, the lack of USE_NSEC meant "do not record nor use the nanosecond resolution part of the file timestamps". To avoid problems on filesystems that lose the ns part when the metadata is flushed to the disk and then later read back in, disabling USE_NSEC has been a good idea in general. If you are on a filesystem without such an issue, it does not hurt to read and store them in the cached stat data in the index entries even if your git is compiled without USE_NSEC. The index left with such a version of git can be read by git compiled with USE_NSEC and it can make use of the nanosecond part to optimize the check to see if the path on the filesystem hsa been modified since we last looked at.

By telling the sender that objects reachable from these extra refs are already complete in the receiving end, the number of objects that need to be transfered can be cut down. These entries are sent over the wire with string ".have", instead of the actual names of the refs. This string was chosen so that they are ignored by older programs at the sending end. If we sent some random but valid looking refnames for these entries, "matching refs" rule (triggered when running "git push" without explicit refspecs, where the sender learns what refs the receiver has, and updates only the ones with the names of the refs the sender also has) and "delete missing" rule (triggered when "git push --mirror" is used, where the sender tells the receiver to delete the refs it itself does not have) would try to update/delete them, which is not what we want. This prepares the send-pack (and "push" that runs native protocol) to accept extended existing ref information and make use of it. The ".have" entries are excluded from ref matching rules, and are exempt from deletion rule while pushing with --mirror option, but are still used for pack generation purposes by providing more "bottom" range commits.

|/ | | | | | | | | | | | | | | This shares the connection between getting the remote ref list and getting objects in the first batch. (A second connection is still used to follow tags). When we do not fetch objects (i.e. either ls-remote disconnects after getting list of refs, or we decide we are already up-to-date), we clean up the connection properly; otherwise the connection is left open in need of cleaning up to avoid getting an error message from the remote end when ssh is used.

* fetch-pack: Prepare for a side-band demultiplexer in a thread.Johannes Sixt2007-11-171-26/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | get_pack() receives a pair of file descriptors that communicate with upload-pack at the remote end. In order to support the case where the side-band demultiplexer runs in a thread, and, hence, in the same process as the main routine, we must not close the readable file descriptor early. The handling of the readable fd is changed in the case where upload-pack supports side-band communication: The old code closed the fd after it was inherited to the side-band demultiplexer process. Now we do not close it. The caller (do_fetch_pack) will close it later anyway. The demultiplexer is the only reader, it does not matter that the fd remains open in the main process as well as in unpack-objects/index-pack, which inherits it. The writable fd is not needed in get_pack(), hence, the old code closed the fd. For symmetry with the readable fd, we now do not close it; the caller (do_fetch_pack) will close it later anyway. Therefore, the new behavior is that the channel now remains open during the entire conversation, but this has no ill effects because upload-pack does not read from it once it has begun to send the pack data. For the same reason it does not matter that the writable fd is now inherited to the demultiplexer and unpack-objects/index-pack processes.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * js/forkexec: Use the asyncronous function infrastructure to run the content filter. Avoid a dup2(2) in apply_filter() - start_command() can do it for us. t0021-conversion.sh: Test that the clean filter really cleans content. upload-pack: Run rev-list in an asynchronous function. upload-pack: Move the revision walker into a separate function. Use the asyncronous function infrastructure in builtin-fetch-pack.c. Add infrastructure to run a function asynchronously. upload-pack: Use start_command() to run pack-objects in create_pack_file(). Have start_command() create a pipe to read the stderr of the child. Use start_comand() in builtin-fetch-pack.c instead of explicit fork/exec. Use run_command() to spawn external diff programs instead of fork/exec. Use start_command() to run content filters instead of explicit fork/exec. Use start_command() in git_connect() instead of explicit fork/exec. Change git_connect() to return a struct child_process instead of a pid_t. Conflicts: builtin-fetch-pack.c
| * Use the asyncronous function infrastructure in builtin-fetch-pack.c.Johannes Sixt2007-10-211-21/+18
| | | | | | | | | | | | | | | | | | | | | | | | We run the sideband demultiplexer in an asynchronous function. Note that earlier there was a check in the child process that closed xd[1] only if it was different from xd[0]; this test is no longer needed because git_connect() always returns two different file descriptors (see ec587fde0a76780931c7ac32474c8c000aa45134).
