zsh, branch fork_early

Rationalise use of forks and pipes.

2018-04-20T12:10:14Z

Ensure we _exit instead of returning from execcmd_exec() if we have forked. Before the optimisation code after the fork always ran to the check at the end, but that code is overkill for the logic between the early fork and the existing one. Remove old workaround to fork in caller of execcmd for current shell constructs as no longer needed with early fork below. Close input of newly created pipe on fork (destined for RHS of pipe which we never execute): this replaces a workaround from zsh-workers/32171, commit 9887fc3d7b. Set last1 on early fork as needed by some instances of shell constructs on LHS of pipeline to know they are exiting.

Ensure we _exit if forked in execcmd_exec().

2018-04-20T10:58:19Z

Make early fork even earlier.

2018-04-20T10:28:30Z

It was after our preliminary scan of arguments to find a command. Actually, in the cases of early fork we don't need this information before forking.

42693: Fork early for pipelines.

2018-04-20T10:17:06Z

If executing a command not at the end of a pipeline, and not optimised in the calling code, we can fork before "prefork" substitutions, at the same point as for background commands.

42684 (with extra comments): Fork early if in bg.

2018-04-20T09:36:39Z

In execcmd the case of running the last command in a pipeline asynchronously for the purpose of & and &! is easy to work out, and we can avoid side effects and unnecessary execution time in the parent shell by forking earlier.

42686: Fix previous pgrp patch.

2018-04-19T12:58:10Z

We shouldn't do any fix ups unless the process has actually exited.

42630: Improve process group handling in pipelines.

2018-04-17T16:14:20Z

If process group leader exits, allow a newly forked process to become process leader. If a foreground job, reattach the shell to the terminal until that happens. Unblock signals when reading output for command subsitution so that we can do this reattaching immediately.

This adds the signals after arguments are filtered according to $optchars.

42624 (plus test): avoid freeing memory that's still needed

Before this patch "git branch -d master" would result in "no matches found", while "master" itself should get completed here. The "(bQ)" (added in 527badc23, via 38129?!) does not seem to be necessary anymore: with files "f\[a-z\]o" and "foo", "git add f[a-z]o " offers "f\[a-z\]o", but not "foo".

42324: _git: handle mutually exclusive options

2018-02-12T09:12:22Z

Currently `git show --stat -p` is not considered a valid completion and prevents further completions like `--no-abbrev`. It is a valid use case however to use `--stat` with `-p` (and there is a synonym `--patch-with-stat` for it even). This patch changes `__git_setup_diff_options` to only handle mutually exclusive arguments reported by Git (as a fatal error) in a special way.

42327: _make: complete _files

2018-02-11T19:09:30Z
