2015-05-25http-backend: spool ref negotiation requests to bufferLibravatar Jeff King1-0/+11
When http-backend spawns "upload-pack" to do ref negotiation, it streams the http request body to upload-pack, who then streams the http response back to the client as it reads. In theory, git can go full-duplex; the client can consume our response while it is still sending the request. In practice, however, HTTP is a half-duplex protocol. Even if our client is ready to read and write simultaneously, we may have other HTTP infrastructure in the way, including the webserver that spawns our CGI, or any intermediate proxies. In at least one documented case[1], this leads to deadlock when trying a fetch over http. What happens is basically: 1. Apache proxies the request to the CGI, http-backend. 2. http-backend gzip-inflates the data and sends the result to upload-pack. 3. upload-pack acts on the data and generates output over the pipe back to Apache. Apache isn't reading because it's busy writing (step 1). This works fine most of the time, because the upload-pack output ends up in a system pipe buffer, and Apache reads it as soon as it finishes writing. But if both the request and the response exceed the system pipe buffer size, then we deadlock (Apache blocks writing to http-backend, http-backend blocks writing to upload-pack, and upload-pack blocks writing to Apache). We need to break the deadlock by spooling either the input or the output. In this case, it's ideal to spool the input, because Apache does not start reading either stdout _or_ stderr until we have consumed all of the input. So until we do so, we cannot even get an error message out to the client. The solution is fairly straight-forward: we read the request body into an in-memory buffer in http-backend, freeing up Apache, and then feed the data ourselves to upload-pack. But there are a few important things to note: 1. We limit the in-memory buffer to prevent an obvious denial-of-service attack. This is a new hard limit on requests, but it's unlikely to come into play. The default value is 10MB, which covers even the ridiculous 100,000-ref negotation in the included test (that actually caps out just over 5MB). But it's configurable on the off chance that you don't mind spending some extra memory to make even ridiculous requests work. 2. We must take care only to buffer when we have to. For pushes, the incoming packfile may be of arbitrary size, and we should connect the input directly to receive-pack. There's no deadlock problem here, though, because we do not produce any output until the whole packfile has been read. For upload-pack's initial ref advertisement, we similarly do not need to buffer. Even though we may generate a lot of output, there is no request body at all (i.e., it is a GET, not a POST).

2015-05-20stash: complain about unknown flagsLibravatar Jeff King1-0/+4
The option parser for git-stash stuffs unknown flags into the $FLAGS variable, where they can be accessed by the individual commands. However, most commands do not even look at these extra flags, leading to unexpected results like this: $ git stash drop --help Dropped refs/stash@{0} (e6cf6d80faf92bb7828f7b60c47fc61c03bd30a1) We should notice the extra flags and bail. Rather than annotate each command to reject a non-empty $FLAGS variable, we can notice that "stash show" is the only command that actually _wants_ arbitrary flags. So we switch the default mode to reject unknown flags, and let stash_show() opt into the feature.

Back when these tests were written, we wanted to make sure that Git notices it is in a bare repository and "git show -s HEAD" would refrain from complaining that HEAD might mean a file it sees in its current working directory (because it does not). But the version of Git back then didn't behave well, without (doubly) being told that it is inside a bare repository by exporting "GIT_DIR=.". The form of the test we originally wanted to have was left commented out as a reminder. Nowadays the test as originally intended works, so add it to the test suite.

2015-05-18pull: make pull.ff=true override merge.ffLibravatar Paul Tan1-0/+8
Since b814da8 (pull: add pull.ff configuration, 2014-01-15), running git-pull with the configuration pull.ff=false or pull.ff=only is equivalent to passing --no-ff and --ff-only to git-merge. However, if pull.ff=true, no switch is passed to git-merge. This leads to the confusing behavior where pull.ff=false or pull.ff=only is able to override merge.ff, while pull.ff=true is unable to.

2015-05-18sha1_file: pass empty buffer to index empty fileLibravatar Jim Hill1-0/+26
`git add` of an empty file with a filter pops complaints from `copy_fd` about a bad file descriptor. This traces back to these lines in sha1_file.c:index_core: if (!size) { ret = index_mem(sha1, NULL, size, type, path, flags); The problem here is that content to be added to the index can be supplied from an fd, or from a memory buffer, or from a pathname. This call is supplying a NULL buffer pointer and a zero size. Downstream logic takes the complete absence of a buffer to mean the data is to be found elsewhere -- for instance, these, from convert.c: if (params->src) { write_err = (write_in_full(child_process.in, params->src, params->size) < 0); } else { write_err = copy_fd(params->fd, child_process.in); } ~If there's a buffer, write from that, otherwise the data must be coming from an open fd.~ Perfectly reasonable logic in a routine that's going to write from either a buffer or an fd. So change `index_core` to supply an empty buffer when indexing an empty file. There's a patch out there that instead changes the logic quoted above to take a `-1` fd to mean "use the buffer", but it seems to me that the distinction between a missing buffer and an empty one carries intrinsic semantics, where the logic change is adapting the code to handle incorrect arguments.

2015-05-14lock_packed_refs(): allow retries when acquiring the packed-refs lockLibravatar Michael Haggerty1-0/+17
Currently, there is only one attempt to acquire any lockfile, and if the lock is held by another process, the locking attempt fails immediately. This is not such a limitation for loose reference files. First, they don't take long to rewrite. Second, most reference updates have a known "old" value, so if another process is updating a reference at the same moment that we are trying to lock it, then probably the expected "old" value will not longer be valid, and the update will fail anyway. But these arguments do not hold for packed-refs: * The packed-refs file can be large and take significant time to rewrite. * Many references are stored in a single packed-refs file, so it could be that the other process was changing a different reference than the one that we are interested in. Therefore, it is much more likely for there to be spurious lock conflicts in connection to the packed-refs file, resulting in unnecessary command failures. So, if the first attempt to lock the packed-refs file fails, continue retrying for a configurable length of time before giving up. The default timeout is 1 second.

2015-05-13log: decorate HEAD with branch name under --decorate=full, tooLibravatar Junio C Hamano1-1/+1
The previous step to teach "log --decorate" to show "HEAD -> master" instead of "HEAD, master" when showing the commit at the tip of the 'master' branch, when the 'master' branch is checked out, did not work for "log --decorate=full". The commands in the "log" family prepare commit decorations for all refs upfront, and the actual string used in a decoration depends on how load_ref_decorations() is called very early in the process. By default, "git log --decorate" stores names with common prefixes such as "refs/heads" stripped; "git log --decorate=full" stores the full refnames. When the current_pointed_by_HEAD() function has to decide if "HEAD" points at the branch a decoration describes, however, what was passed to load_ref_decorations() to decide to strip (or keep) such a common prefix is long lost. This makes it impossible to reliably tell if a decoration that stores "refs/heads/master", for example, is the 'master' branch (under "--decorate" with prefix omitted) or 'refs/heads/master' branch (under "--decorate=full"). Keep what was passed to load_ref_decorations() in a global next to the global variable name_decoration, and use that to decide how to match what was read from "HEAD" and what is in a decoration.

2015-05-12ref_transaction_commit(): fix atomicity and avoid fd exhaustionLibravatar Michael Haggerty1-2/+2
The old code was roughly for update in updates: acquire locks and check old_sha for update in updates: if changing value: write_ref_to_lockfile() commit_ref_update() for update in updates: if deleting value: unlink() rewrite packed-refs file for update in updates: if reference still locked: unlock_ref() This has two problems. Non-atomic updates ================== The atomicity of the reference transaction depends on all pre-checks being done in the first loop, before any changes have started being committed in the second loop. The problem is that write_ref_to_lockfile() (previously part of write_ref_sha1()), which is called from the second loop, contains two more checks: * It verifies that new_sha1 is a valid object * If the reference being updated is a branch, it verifies that new_sha1 points at a commit object (as opposed to a tag, tree, or blob). If either of these checks fails, the "transaction" is aborted during the second loop. But this might happen after some reference updates have already been permanently committed. In other words, the all-or-nothing promise of "git update-ref --stdin" could be violated. So these checks have to be moved to the first loop. File descriptor exhaustion ========================== The old code locked all of the references in the first loop, leaving all of the lockfiles open until later loops. Since we might be updating a lot of references, this could result in file descriptor exhaustion. The solution ============ After this patch, the code looks like for update in updates: acquire locks and check old_sha if changing value: write_ref_to_lockfile() else: close_ref() for update in updates: if changing value: commit_ref_update() for update in updates: if deleting value: unlink() rewrite packed-refs file for update in updates: if reference still locked: unlock_ref() This fixes both problems: 1. The pre-checks in write_ref_to_lockfile() are now done in the first loop, before any changes have been committed. If any of the checks fails, the whole transaction can now be rolled back correctly. 2. All lockfiles are closed in the first loop immediately after they are created (either by write_ref_to_lockfile() or by close_ref()). This means that there is never more than one open lockfile at a time, preventing file descriptor exhaustion. To simplify the bookkeeping across loops, add a new REF_NEEDS_COMMIT bit to update->flags, which keeps track of whether the corresponding lockfile needs to be committed, as opposed to just unlocked. (Since "struct ref_update" is internal to the refs module, this change is not visible to external callers.) This change fixes two tests in t1400.

To get the name of all config variables in a given section we perform a 'git config --get-regex' query for all config variables containing the name of that section, and then filter its output through a case statement to throw away those that though contain but don't start with the given section. Modify the regex to match only at the beginning, so the case statement becomes unnecessary and we can get rid of it. Add a test to check that a match in the middle doesn't fool us.

2015-05-12completion: add a helper function to get config variablesLibravatar SZEDER Gábor1-0/+22
Currently there are a few completion functions that perform similar 'git config' queries and filtering to get config variable names: the completion of pretty aliases, aliases, and remote groups for 'git remote update'. Unify those 'git config' queries in a helper function to eliminate code duplication. Though the helper functions to get pretty aliases and alieses are reduced to mere one-liner wrappers around the newly added function, keep these helpers still, because users' completion functions out there might depend on them. And they keep their callers a tad easier to read, too. Add tests for the pretty alias and alias helper to show that they work as before; not for the remote groups query, though, because that's not extracted into a helper function and it's not worth the effort to do so for a sole callsite.

2015-05-11Merge branch 'mm/usage-log-l-can-take-regex' into maint-2.3Libravatar Junio C Hamano1-4/+4
Documentation fix. * mm/usage-log-l-can-take-regex: log -L: improve error message on malformed argument Documentation: change -L:<regex> to -L:<funcname>
2015-05-11Merge branch 'jc/diff-no-index-d-f' into maint-2.3Libravatar Junio C Hamano1-0/+34
The usual "git diff" when seeing a file turning into a directory showed a patchset to remove the file and create all files in the directory, but "git diff --no-index" simply refused to work. Also, when asked to compare a file and a directory, imitate POSIX "diff" and compare the file with the file with the same name in the directory, instead of refusing to run. * jc/diff-no-index-d-f: diff-no-index: align D/F handling with that of normal Git diff-no-index: DWIM "diff D F" into "diff D/F F"

"hash-object --literally" introduced in v2.2 was not prepared to take a really long object type name. * jc/hash-object: write_sha1_file(): do not use a separate sha1[] array t1007: add hash-object --literally tests hash-object --literally: fix buffer overrun with extra-long object type git-hash-object.txt: document --literally option
2015-05-11Merge branch 'jk/filter-branch-use-of-sed-on-incomplete-line'Libravatar Junio C Hamano1-0/+10
"filter-branch" corrupted commit log message that ends with an incomplete line on platforms with some "sed" implementations that munge such a line. Work it around by avoiding to use "sed". * jk/filter-branch-use-of-sed-on-incomplete-line: filter-branch: avoid passing commit message through sed
2015-05-11Merge branch 'tb/blame-resurrect-convert-to-git'Libravatar Junio C Hamano1-3/+15
Some time ago, "git blame" (incorrectly) lost the convert_to_git() call when synthesizing a fake "tip" commit that represents the state in the working tree, which broke folks who record the history with LF line ending to make their project portabile across platforms while terminating lines in their working tree files with CRLF for their platform. * tb/blame-resurrect-convert-to-git: blame: CRLF in the working tree and LF in the repo
