| | | | | | | | | | | If we reach EOF after the SHA1-then-TAB, yet before the NUL that terminates each file name, we would fill the file name buffer with \255 bytes resulting from the repeatedly-failing fgetc (returns EOF/-1) and ultimately complain about "filename too long", because no NUL was encountered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 09c9957c fixes a deadlock in which pack-objects fails, the remote end is still waiting for pack data, and we are still waiting for the remote end to say something (see that commit for a much more in-depth explanation). We solved the problem there by making sure the output pipe is closed on error; thus the remote sees EOF, and proceeds to complain and close its end of the connection. However, in the special case of push over git://, we don't have a pipe, but rather a full-duplex socket, with another dup()-ed descriptor in place of the second half of the pipe. In this case, closing the second descriptor signals nothing to the remote end, and we still deadlock. This patch calls shutdown() explicitly to signal EOF to the other side.

| * connect: let callers know if connection is a socketJeff King2011-05-16
| | | | | | | | | | | | | | | | | | | | | | | | They might care because they want to do a half-duplex close. With pipes, that means simply closing the output descriptor; with a socket, you must actually call shutdown. Instead of exposing the magic no_fork child_process struct, let's encapsulate the test in a function. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * connect: treat generic proxy processes like ssh processesJeff King2011-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The git_connect function returns two ends of a pipe for talking with a remote, plus a struct child_process representing the other end of the pipe. If we have a direct socket connection, then this points to a special "no_fork" child process. The code path for doing git-over-pipes or git-over-ssh sets up this child process to point to the child git command or the ssh process. When we call finish_connect eventually, we check wait() on the command and report its return value. The code path for git://, on the other hand, always sets it to no_fork. In the case of a direct TCP connection, this makes sense; we have no child process. But in the case of a proxy command (configured by core.gitproxy), we do have a child process, but we throw away its pid, and therefore ignore its return code. Instead, let's keep that information in the proxy case, and respect its return code, which can help catch some errors (though depending on your proxy command, it will be errors reported by the proxy command itself, and not propagated from git commands. Still, it is probably better to propagate such errors than to ignore them). It also means that the child_process field can reliably be used to determine whether the returned descriptors are actually a full-duplex socket, which means we should be using shutdown() instead of a simple close.

Basically the deadlock can happen when pack-objects fails, and the descriptor to upstream is left open. We never send the pack, so the upstream is left waiting for us to say something, and we are left waiting for upstream to close the connection. In the non-rpc case, our descriptor points straight to the upstream. We hand it off to run-command, which takes ownership and closes the descriptor after pack-objects finishes (whether it succeeds or not). Commit 09c9957 tried to emulate that in the rpc case. That isn't right, though. We actually have a descriptor going back to the remote-helper, and we need to keep using it after pack-objects is finished. Closing it early completely breaks pushing via smart-http. We still need to do something on error to signal the remote-helper that we won't be sending any pack data (otherwise we get the deadlock). In an ideal world, we would send a special packet back that says "Sorry, there was an error". But the remote-helper doesn't understand any such packet, so the best we can do is close the descriptor and let it report that we hung up unexpectedly.

| | * send-pack: avoid deadlock when pack-object dies earlyJohannes Sixt2011-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Send-pack deadlocks in two ways when pack-object dies early (for example, because there is some repo corruption). The first deadlock happens with the smart push protocol (--stateless-rpc). After the initial rev-exchange, the remote is waiting for the pack data to arrive, and the sideband demuxer at the local side continues trying to stream data from the remote repository until it gets EOF. Meanwhile, send-pack (in function pack_objects()) has noticed that pack-objects did not produce output and died. Back in send_pack(), it now tries to clean up the sideband demuxer using finish_async(). The demuxer, however, waits for the remote end to close down, the remote waits for pack data, and the reason that it still waits is that send-pack forgot to close the outgoing channel. Add the missing close() in pack_objects(). The second deadlock happens in a similar constellation when the sideband demuxer runs in a forked process (rather than in a thread). Again, the remote end waits for pack data to arrive, the sideband demuxer waits for the remote to shut down, and send-pack (in the regular clean-up) waits for the demuxer to terminate. This time, the send-pack parent process closes the writable end of the outgoing channel (in start_command() that spawned pack-objects) so that after the death of the pack-objects process all writable ends should have been closed and the remote repo should see EOF. This does not happen, however, because when the sideband demuxer was forked earlier, it also inherited a writable end; it remains open and keeps the remote repo from seeing EOF. To break this deadlock, close the writable end in the demuxer. Analyzed-by: Jeff King <peff@peff.net> Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

What happens is this: 1. Upload-pack is informed we are doing a shallow clone. 2. We call start_async() to spawn a thread that will generate rev-list results to feed to pack-objects. It gets a file descriptor to a pipe which will eventually hook to pack-objects. 3. The rev-list thread uses fdopen to create a new output stream around the fd we gave it, called pack_pipe. 4. The thread writes results to pack_pipe. Outside of our control, libc is doing locking on the stream. We keep writing until the OS pipe buffer is full, and then we block in write(), still holding the lock. 5. The main thread now uses start_command to spawn pack-objects. Before forking, it calls fflush(NULL) to flush every stdio output buffer. It blocks trying to get the lock on pack_pipe. And we have a deadlock. The thread will block until somebody starts reading from the pipe. But nobody will read from the pipe until we finish flushing to the pipe. To fix this, we swap the start order: we start the pack-objects reader first, and then the rev-list writer after. Thus the problematic fflush(NULL) happens before we even open the new file descriptor (and even if it didn't, flushing should no longer block, as the reader at the end of the pipe is now active).

There are 5 callers of module_list; they all read (mode, sha1, stage, path) tuple, and most of them care only about path. As a first level approximation, it should be Ok (in the sense that it does not make things worse than it currently is) to filter the duplicate paths from module_list output, but some callers should change their behaviour when the merge in the superproject still has conflicts. Notice the higher-stage entries, and emit only one record from module_list, but while doing so, mark the entry with "U" (not [0-3]) in the $stage field and null out the SHA-1 part, as the object name for the lowest stage does not give any useful information to the caller, and this way any caller that uses the object name would hopefully barf. Then update the codepaths for each subcommands this way: - "update" should not touch the submodule repository, because we do not know what commit should be checked out yet. - "status" reports the conflicting submodules as 'U000...000' and does not recurse into them (we might later want to make it recurse). - The command called by "foreach" may want to do whatever it wants to do by noticing the merged status in the superproject itself, so feed the path to it from module_list as before, but only once per submodule. - "init" and "sync" are unlikely things to do while the superproject is still not merged, but as long as a submodule is there in $path, there is no point skipping it. It might however want to take the merged status of .gitmodules into account, but that is outside of the scope of this topic.

Back then I thought that 65k revisions was a lot (it was what we were about to hit in BK), and each revision tends to be about 5-10 new objects or so, so a million objects was a big number. These days, the kernel isn't even the largest git project, and even the kernel has about 220k revisions (_much_ bigger than the BK tree ever was) and we are approaching two million objects. At that point, seven hex digits is still unique for a lot of them, but when we're talking about just two orders of magnitude difference between number of objects and the hash size, there _will_ be collisions in truncated hash values. It's no longer even close to unrealistic - it happens all the time. We should both increase the default abbrev that was unrealistically small, _and_ add a way for people to set their own default per-project in the git config file. This is the first step to first make it configurable; the default of 7 is not raised yet. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Hence "--max-count=10 -Sfoo" meant "examine the 10 first revisions, and out of them, show only those changing the occurences of foo", not "show 10 revisions changing the occurences of foo". In case the commit isn't actually shown, cancel the decrement of max_count. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In the past, we just assumed that single-line headers would be reasonably short. For multi-line subjects that we squish into a single line, we just "pre-folded" the data in pp_title_line by adding a newline and indentation. There were two problems. One is that, although rare, single-line messages can actually be longer than the recommended line-length limits. The second is that the pre-folding interacted badly with rfc2047 encoding, leading to malformed headers. Instead, let's stop pre-folding the subject lines, and just fold everything based on length in add_rfc2047, whether it is encoded or not.

This makes it annoying to wrap strings we have as a pointer and a length. Refactoring strbuf_add_wrapped_text and all of its sub-functions to handle fixed-length strings turned out to be really ugly. So this implementation is lame; it just strdups the text and operates on the NUL-terminated version. This should be fine as the strings we are wrapping are generally pretty short. If it becomes a problem, we can optimize later. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
