2016-01-20Merge branch 'mh/notes-allow-reading-treeish'Libravatar Junio C Hamano1-0/+10
Some "git notes" operations, e.g. "git log --notes=<note>", should be able to read notes from any tree-ish that is shaped like a notes tree, but the notes infrastructure required that the argument must be a ref under refs/notes/. Loosen it to require a valid ref only when the operation would update the notes (in which case we must have a place to store the updated notes tree, iow, a ref). * mh/notes-allow-reading-treeish: notes: allow treeish expressions as notes ref
2016-01-12Merge branch 'sb/submodule-parallel-fetch'Libravatar Junio C Hamano2-25/+99
Add a framework to spawn a group of processes in parallel, and use it to run "git fetch --recurse-submodules" in parallel. Rerolled and this seems to be a lot cleaner. The merge of the earlier one to 'next' has been reverted. * sb/submodule-parallel-fetch: submodules: allow parallel fetching, add tests and documentation fetch_populated_submodules: use new parallel job processing run-command: add an asynchronous parallel child processor sigchain: add command to pop all common signals strbuf: add strbuf_read_once to read without blocking xread: poll on non blocking fds submodule.c: write "Fetching submodule <foo>" to stderr
2016-01-12Merge branch 'nd/stop-setenv-work-tree'Libravatar Junio C Hamano1-1/+1
An earlier change in 2.5.x-era broke users' hooks and aliases by exporting GIT_WORK_TREE to point at the root of the working tree, interfering when they tried to use a different working tree without setting GIT_WORK_TREE environment themselves. * nd/stop-setenv-work-tree: Revert "setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR"
2016-01-12notes: allow treeish expressions as notes refLibravatar Mike Hommey1-0/+10
init_notes() is the main point of entry to the notes API. It ensures that the input can be used as ref, because it needs a ref to update to store notes tree after modifying it. There however are many use cases where notes tree is only read, e.g. "git log --notes=...". Any notes-shaped treeish could be used for such purpose, but it is not allowed due to existing restriction. Allow treeish expressions to be used in the case the notes tree is going to be used without write "permissions". Add a flag to distinguish whether the notes tree is intended to be used read-only, or will be updated. With this change, operations that use notes read-only can be fed any notes-shaped tree-ish can be used, e.g. git log --notes=notes@{1}.

2015-12-22Revert "setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR"Libravatar Nguyễn Thái Ngọc Duy1-1/+1
This reverts d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR, 2015-06-26). It has caused three regression reports so far. http://article.gmane.org/gmane.comp.version-control.git/281608 http://article.gmane.org/gmane.comp.version-control.git/281979 http://article.gmane.org/gmane.comp.version-control.git/282691 All of them are about spawning git subprocesses, where the new presence of GIT_WORK_TREE either changes command behaviour (git-init or git-clone), or how repo/worktree is detected (from aliases), with or without $GIT_DIR.

2015-12-17revision.c: propagate tag names from pending arrayLibravatar Jeff King1-0/+29
When we unwrap a tag to find its commit for a traversal, we do not propagate the "name" field of the tag in the pending array (i.e., the ref name the user gave us in the first place) to the commit (instead, we use an empty string). This means that "git log --source" will never show the tag-name for commits we reach through it. This was broken in 2073949 (traverse_commit_list: support pending blobs/trees with paths, 2014-10-15). That commit tried to be careful and avoid propagating the path information for a tag (which would be nonsensical) to trees and blobs. But it should not have cut off the "name" field, which should carry forward to children. Note that this does mean that the "name" field will carry forward to blobs and trees, too. Whereas prior to 2073949, we always gave them an empty string. This is the right thing to do, but in practice no callers probably use it (since now we have an explicit separate "path" field, which was the point of 2073949). We add tests here not only for the broken case, but also a basic sanity test of "log --source" in general, which did not have any coverage in the test suite.

2015-12-16run-command: add an asynchronous parallel child processorLibravatar Stefan Beller1-0/+53
This allows to run external commands in parallel with ordered output on stderr. If we run external commands in parallel we cannot pipe the output directly to the our stdout/err as it would mix up. So each process's output will flow through a pipe, which we buffer. One subprocess can be directly piped to out stdout/err for a low latency feedback to the user. Example: Let's assume we have 5 submodules A,B,C,D,E and each fetch takes a different amount of time as the different submodules vary in size, then the output of fetches in sequential order might look like this: time --> output: |---A---| |-B-| |-------C-------| |-D-| |-E-| When we schedule these submodules into maximal two parallel processes, a schedule and sample output over time may look like this: process 1: |---A---| |-D-| |-E-| process 2: |-B-| |-------C-------| output: |---A---|B|---C-------|DE So A will be perceived as it would run normally in the single child version. As B has finished by the time A is done, we can dump its whole progress buffer on stderr, such that it looks like it finished in no time. Once that is done, C is determined to be the visible child and its progress will be reported in real time. So this way of output is really good for human consumption, as it only changes the timing, not the actual output. For machine consumption the output needs to be prepared in the tasks, by either having a prefix per line or per block to indicate whose tasks output is displayed, because the output order may not follow the original sequential ordering: |----A----| |--B--| |-C-| will be scheduled to be all parallel: process 1: |----A----| process 2: |--B--| process 3: |-C-| output: |----A----|CB This happens because C finished before B did, so it will be queued for output before B. To detect when a child has finished executing, we check interleaved with other actions (such as checking the liveliness of children or starting new processes) whether the stderr pipe still exists. Once a child closed its stderr stream, we assume it is terminating very soon, and use `finish_command()` from the single external process execution interface to collect the exit status. By maintaining the strong assumption of stderr being open until the very end of a child process, we can avoid other hassle such as an implementation using `waitpid(-1)`, which is not implemented in Windows.

The "Pushing submodule <foo>" progress output correctly goes to stderr, but "Fetching submodule <foo>" is going to stdout by mistake. Fix it to write to stderr. Noticed while trying to implement a parallel submodule fetch. When this particular output line went to a different file descriptor, it was buffered separately, resulting in wrongly interleaved output if we copied it to the terminal naively.

2015-12-11rebase -i: remember merge options beyond continue actionsLibravatar Fabian Ruch1-0/+16
If the user explicitly specified a merge strategy or strategy options, continue to use that strategy/option after "rebase --continue". Add a test of the corrected behavior. If --merge is specified or implied by -s or -X, then "strategy and "strategy_opts" are set to values from which "strategy_args" can be derived; otherwise they are set to empty strings. Either way, their values are propagated from one step of an interactive rebase to the next via state files. "do_merge", on the other hand, is *not* propagated to later steps of an interactive rebase. Therefore, making the initialization of "strategy_args" conditional on "do_merge" being set prevents later steps of an interactive rebase from setting it correctly. Luckily, we don't need the "do_merge" guard at all. If the rebase was started without --merge, then "strategy" and "strategy_opts" are both the empty string, which results in "strategy_args" also being set to the empty string, which is just what we want in that situation. So remove the "do_merge" guard and derive "strategy_args" from "strategy" and "strategy_opts" every time.

t5516 "75 - deny fetch unreachable SHA1, allowtipsha1inwant=true" is flaky in the following case: 1. remote upload-pack finds out "not our ref" 2. remote sends a response and closes the pipe 3. fetch-pack still tries to write commands to the remote upload-pack 4. write call in wrapper.c dies with SIGPIPE The test is flaky because the sending fetch-pack may or may not have finished writing its output by step (3). If it did, then we see a closed pipe on the next read() call. If it didn't, then we get the SIGPIPE from step (4) above. Both are fine, but the latter fools test_must_fail. t5504 "9 - push with transfer.fsckobjects" is flaky, too, and returns SIGPIPE once in a while. I had to remove the final "To dst..." output check because there is no output if the process dies with SIGPIPE. Accept such a death-with-sigpipe also as OK when we are expecting a failure.
