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.

2015-12-16submodule.c: write "Fetching submodule <foo>" to stderrLibravatar Jonathan Nieder1-25/+26
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.

2015-11-28add "ok=sigpipe" to test_must_fail and use it to fix flaky testsLibravatar Lars Schneider3-6/+8
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.

2015-11-24filter-branch: deal with object name vs. pathname ambiguity in tree-filterLibravatar SZEDER Gábor1-0/+7
'git filter-branch' fails complaining about an ambiguous argument, if a tree-filter renames a path and the new pathname happens to match an existing object name. After the tree-filter has been applied, 'git filter-branch' looks for changed paths by running: git diff-index -r --name-only --ignore-submodules $commit which then, because of the lack of disambiguating double-dash, can't decide whether to treat '$commit' as revision or path and errors out. Add that disambiguating double-dash after 'git diff-index's revision argument to make sure that '$commit' is interpreted as a revision.

2015-11-24blame: fix object casting regressionLibravatar Jeff King1-0/+7
Commit 1b0d400 refactored the prepare_final() function so that it could be reused in multiple places. Originally, the loop had two outputs: a commit to stuff into sb->final, and the name of the commit from the rev->pending array. After the refactor, that loop is put in its own function with a single return value: the object_array_entry from the rev->pending array. This contains both the name and the object, but with one important difference: the object is the _original_ object found by the revision parser, not the dereferenced commit. If one feeds a tag to "git blame", we end up casting the tag object to a "struct commit", which causes a segfault. Instead, let's return the commit (properly casted) directly from the function, and take the "name" as an optional out-parameter. This does the right thing, and actually simplifies the callers, who no longer need to cast or dereference the object_array_entry themselves.

2015-11-24bash prompt: indicate dirty index even on orphan branchesLibravatar SZEDER Gábor1-2/+2
__git_ps1() doesn't indicate dirty index while on an orphan branch. To check the dirtiness of the index, __git_ps1() runs 'git diff-index --cached ... HEAD', which doesn't work on an orphan branch, because HEAD doesn't point to a valid commit. Run 'git diff ... --cached' instead, as it does the right thing both on valid and invalid HEAD, i.e. compares the index to the existing HEAD in the former case and to the empty tree in the latter. This fixes the two failing tests added in the first commit of this series. The dirtiness of the worktree is already checked with 'git diff' and is displayed correctly even on an orphan branch.

2015-11-24bash prompt: test dirty index and worktree while on an orphan branchLibravatar SZEDER Gábor1-3/+28
There is only a single test exercising the dirty state indicator on an orphan branch, and in that test neither the index nor the worktree are dirty. Add two failing tests to check the dirty state indicator while either the index is dirty or while both the index and the worktree are dirty on an orphan branch, and to show that the dirtiness of the index is not displayed in these cases (the fourth combination, i.e. clean index and dirty worktree are impossible on an orphan branch). Update the existing dirty state indicator on clean orphan branch test to match the style of the two new tests, most importantly to use 'git checkout --orphan' instead of cd-ing into a repository that just happens to be empty and clean.

2015-11-20sendemail: teach git-send-email to dump alias namesLibravatar Jacob Keller1-0/+82
Add an option "--dump-aliases" which changes the default behavior of git-send-email. This mode will simply read the alias files configured by sendemail.aliasesfile and sendemail.aliasfiletype and dump a list of all configured aliases, one per line. The intended use case for this option is the bash-completion script which will use it to autocomplete aliases on the options which take addresses. Add some tests for the new option using various alias file formats. A possible future extension to the alias dump format could be done by extending the --dump-aliases to take an optional argument defining the format to display.
