2013-10-30Merge branch 'jl/pack-transfer-avoid-double-close'Libravatar Junio C Hamano1-0/+4
The codepath that send_pack() calls pack_objects() mistakenly closed the same file descriptor twice, leading to potentially closing a wrong file descriptor that was opened in the meantime. * jl/pack-transfer-avoid-double-close: Clear fd after closing to avoid double-close error
2013-10-23Clear fd after closing to avoid double-close errorLibravatar Jens Lindstrom1-0/+4
In send_pack(), clear the fd passed to pack_objects() by setting it to -1, since pack_objects() closes the fd (via a call to run_command()). Likewise, in get_pack(), clear the fd passed to run_command(). Not doing so risks having git_transport_push(), caller of send_pack(), closing the fd again, possibly incorrectly closing some other open file; or similarly with fetch_refs_from_pack(), indirect caller of get_pack().

2013-07-22push --force-with-lease: tie it all togetherLibravatar Junio C Hamano1-0/+1

2013-07-08cache.h: move remote/connect API out of itLibravatar Junio C Hamano1-0/+1
The definition of "struct ref" in "cache.h", a header file so central to the system, always confused me. This structure is not about the local ref used by sha1-name API to name local objects. It is what refspecs are expanded into, after finding out what refs the other side has, to define what refs are updated after object transfer succeeds to what values. It belongs to "remote.h" together with "struct refspec". While we are at it, also move the types and functions related to the Git transport connection to a new header file connect.h Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-02-20pkt-line: provide a LARGE_PACKET_MAX static bufferLibravatar Jeff King1-4/+3
Most of the callers of packet_read_line just read into a static 1000-byte buffer (callers which handle arbitrary binary data already use LARGE_PACKET_MAX). This works fine in practice, because: 1. The only variable-sized data in these lines is a ref name, and refs tend to be a lot shorter than 1000 characters. 2. When sending ref lines, git-core always limits itself to 1000 byte packets. However, the only limit given in the protocol specification in Documentation/technical/protocol-common.txt is LARGE_PACKET_MAX; the 1000 byte limit is mentioned only in pack-protocol.txt, and then only describing what we write, not as a specific limit for readers. This patch lets us bump the 1000-byte limit to LARGE_PACKET_MAX. Even though git-core will never write a packet where this makes a difference, there are two good reasons to do this: 1. Other git implementations may have followed protocol-common.txt and used a larger maximum size. We don't bump into it in practice because it would involve very long ref names. 2. We may want to increase the 1000-byte limit one day. Since packets are transferred before any capabilities, it's difficult to do this in a backwards-compatible way. But if we bump the size of buffer the readers can handle, eventually older versions of git will be obsolete enough that we can justify bumping the writers, as well. We don't have plans to do this anytime soon, but there is no reason not to start the clock ticking now. Just bumping all of the reading bufs to LARGE_PACKET_MAX would waste memory. Instead, since most readers just read into a temporary buffer anyway, let's provide a single static buffer that all callers can use. We can further wrap this detail away by having the packet_read_line wrapper just use the buffer transparently and return a pointer to the static storage. That covers most of the cases, and the remaining ones already read into their own LARGE_PACKET_MAX buffers. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-02-20pkt-line: teach packet_read_line to chomp newlinesLibravatar Jeff King1-5/+1
The packets sent during ref negotiation are all terminated by newline; even though the code to chomp these newlines is short, we end up doing it in a lot of places. This patch teaches packet_read_line to auto-chomp the trailing newline; this lets us get rid of a lot of inline chomping code. As a result, some call-sites which are not reading line-oriented data (e.g., when reading chunks of packfiles alongside sideband) transition away from packet_read_line to the generic packet_read interface. This patch converts all of the existing callsites. Since the function signature of packet_read_line does not change (but its behavior does), there is a possibility of new callsites being introduced in later commits, silently introducing an incompatibility. However, since a later patch in this series will change the signature, such a commit would have to be merged directly into this commit, not to the tip of the series; we can therefore ignore the issue. This is an internal cleanup and should produce no change of behavior in the normal case. However, there is one corner case to note. Callers of packet_read_line have never been able to tell the difference between a flush packet ("0000") and an empty packet ("0004"), as both cause packet_read_line to return a length of 0. Readers treat them identically, even though Documentation/technical/protocol-common.txt says we must not; it also says that implementations should not send an empty pkt-line. By stripping out the newline before the result gets to the caller, we will now treat the newline-only packet ("0005\n") the same as an empty packet, which in turn gets treated like a flush packet. In practice this doesn't matter, as neither empty nor newline-only packets are part of git's protocols (at least not for the line-oriented bits, and readers who are not expecting line-oriented packets will be calling packet_read directly, anyway). But even if we do decide to care about the distinction later, it is orthogonal to this patch. The right place to tighten would be to stop treating empty packets as flush packets, and this change does not make doing so any harder.

This is just write_or_die by another name. The one distinction is that write_or_die will treat EPIPE specially by suppressing error messages. That's fine, as we die by SIGPIPE anyway (and in the off chance that it is disabled, write_or_die will simulate it).

2013-02-20send-pack: prefer prefixcmp over memcmp in receive_statusLibravatar Jeff King1-5/+4
This code predates prefixcmp, so it used memcmp along with static sizes. Replacing these memcmps with prefixcmp makes the code much more readable, and the lack of static sizes will make refactoring it in future patches simpler. Note that we used to be unnecessarily liberal in parsing the "unpack" status line, and would accept "unpack ok\njunk". No version of git has ever produced that, and it violates the BNF in Documentation/technical/pack-protocol.txt. Let's take this opportunity to tighten the check by converting the prefix comparison into a strcmp. While we're in the area, let's also fix a vague error message that does not follow our usual conventions (it writes directly to stderr and does not use the "error:" prefix).

2013-01-24push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCELibravatar Junio C Hamano1-0/+2
When we push to update an existing ref, if: * the object at the tip of the remote is not a commit; or * the object we are pushing is not a commit, it won't be correct to suggest to fetch, integrate and push again, as the old and new objects will not "merge". We should explain that the push must be forced when there is a non-committish object is involved in such a case. If we do not have the current object at the tip of the remote, we do not even know that object, when fetched, is something that can be merged. In such a case, suggesting to pull first just like non-fast-forward case may not be technically correct, but in practice, most such failures are seen when you try to push your work to a branch without knowing that somebody else already pushed to update the same branch since you forked, so "pull first" would work as a suggestion most of the time. And if the object at the tip is not a commit, "pull first" will fail, without making any permanent damage. As a side effect, it also makes the error message the user will get during the next "push" attempt easier to understand, now the user is aware that a non-commit object is involved. In these cases, the current code already rejects such a push on the client end, but we used the same error and advice messages as the ones used when rejecting a non-fast-forward push, i.e. pull from there and integrate before pushing again. Introduce new rejection reasons and reword the messages appropriately. [jc: with help by Peff on message details] Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-10-18send-pack: don't update tracking refs on errorLibravatar Jeff King1-16/+34
Previously, we updated the tracking refs (which match refs we are pushing) while generating the list of refs to send. However, at that point we don't know whether the refs were accepted. Instead, we now wait until we get a response code from the server. If an error was indicated, we don't update any local tracking refs. Technically some refs could have been updated on the remote, but since the local ref update is just an optimization to avoid an extra fetch, we are better off erring on the side of correctness.

send-pack builds a pipeline that runs "rev-list | pack-objects" and sends the output from pack-objects to the other side, while feeding the input side of that pipe from itself. However, the file descriptor that is given to this pipeline (so that it can be dup2(2)'ed into file descriptor 1 of pack-objects) is closed by the caller before the complex fork+exec dance! Worse yet, the caller already dup2's it to 1, so the child process did not even have to. I do not understand how this code could possibly have been working, but it somehow was working by accident. Merging the sliding mmap() code reveals this problem, presumably because it keeps one extra file descriptor open for a packfile and changes the way file descriptors are allocated. I am too tired to diagnose the problem now, but this seems to be a sensible fix. Signed-off-by: Junio C Hamano <junkio@cox.net>

When we are generating packs to update remote repositories we want to supply as much information as possible about the revisions that already exist to rev-list in order optimise the pack as much as possible. We need to pass two revisions for each branch we are updating in the remote repository and one for each additional branch. Where the remote repository has numerous branches we can run out of command line space to pass them. Utilise the git-rev-list --stdin mode to allow unlimited numbers of revision constraints. This allows us to move back to the much simpler unordered revision selection code. [jc: added some comments in the code to describe the pipe flow a bit.] Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-08-23Convert memcpy(a,b,20) to hashcpy(a,b).Libravatar Shawn Pearce1-2/+2
This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.
