* Clean up some job status messagesGravatar ridiculousfish2014-11-03
| | | | | | | Stop printing anything for jobs terminated via ^C. Don't list the job number if it's the only job. Fixes #1119
* Reintroduce "Stop reaping children from SIGCHLD handler"Gravatar ridiculousfish2014-10-25
| | | | | This re-introduces 3fe10692199fc20a5f4b6ac5057cce43babc5f36 with some associated fixes to address #1768.
* Revert "Stop reaping children from SIGCHLD signal handler"Gravatar ridiculousfish2014-10-21
| | | | | | This reverts commit 3fe10692199fc20a5f4b6ac5057cce43babc5f36. In light of #1768
* Stop reaping children from SIGCHLD signal handlerGravatar ridiculousfish2014-10-20
| | | | | | | | | | | | | | | | | | | | | | Prior to this fix, a child process may be reaped in one of two ways: 1. By a call to waitpid() within job_continue 2. By a call to waitpid() within the SIGCHLD signal handler Only the second call was with the WNOHANG option. Thus if the signal handler fired first, and then the waitpid call fired, we could get a deadlock because we'd end up waiting on a long-running process. I have not been able to reproduce this on fish 1.x, though it seems like it ought to reproduce there too. This fix migrates the waitpid() call out of the signal handler; the second class of calls moves to job_reap. This eliminates the possibility of a race, because we check for job completion before calling waitpid, and there is no longer the possibility of the job being marked as complete asynchronously. It also results in a massive conceptual simplification, since the signal handler is now very simple and easy to reason about (no more walking jobs lists, etc). This partially fixes a bug reported in #1273
* Remove some obsolete job flagsGravatar Kevin Ballard2014-10-13

| | | | | | | | | | | | | | | | | | | | redirections for a process were flattened into a big list associated with the job, so there was no way to tell which redirections applied to each process. Each process therefore got all the redirections associated with the job. See https://github.com/fish-shell/fish-shell/issues/877 for how this could manifest. With this change, jobs only track their block-level redirections. Process level redirections are correctly associated with the process, and at exec time we stitch them together (block, pipe, and process redirects). This fixes the weird issues where redirects bleed across pipelines (like #877), and also allows us to play with the order in which redirections are applied, since the final list is constructed right before it's needed. This lets us put pipes after block level redirections but before process level redirections, so that a 2>&1-type redirection gets picked up after the pipe, i.e. it should fix https://github.com/fish-shell/fish-shell/issues/110 This is a significant change. The tests all pass. Cross your fingers.
