Extended & human-friendly keys See the changelog additions for user-visible changes. Since we enable/disable terminal protocols whenever we pass terminal ownership, tests can no longer run in parallel on the same terminal. For the same reason, readline shortcuts in the gdb REPL will not work anymore. As a remedy, use gdbserver, or lobby for CSI u support in libreadline. Add sleep to some tests, otherwise they fall (both in CI and locally). There are two weird failures on FreeBSD remaining, disable them for now https://github.com/fish-shell/fish-shell/pull/10359/checks?check_run_id=23330096362 Design and implementation borrows heavily from Kakoune. In future, we should try to implement more of the kitty progressive enhancements. Closes #10359 2024-03-30 15:10:12 +00:00			`#RUN: env fth=%fish_test_helper fish=%fish %fish %s \| %filter-ctrlseqs`
Improve support for job control in non-interactive scenarios Avoid complaining about ENOTTY results from tcsetpgrp, and ensure we ignore SIGTTOU the first time job control is enabled. 2020-01-30 23:16:03 +00:00

Bravely remove reclaim... param from continue_job, and rework tcsetpgrp calls This changes how fish attempts to protect itself from calling tcsetpgrp() too aggressively. Recall that tcsetpgrp() will "force" itself, if SIGTTOU is ignored (which it is in fish when job control is enabled). Prior to this fix, we avoided SIGTTINs by only transferring the tty ownership if fish was already the owner. This dated from a time before we had really nailed down how pgroups should be assigned. Now we more deliberately assign a job's pgroup so we don't need this conservative check. However we still need logic to avoid transferring the tty if fish is not the owner. The bad case is when job control is enabled while fish is running in the background - here fish would transfer the tty and "steal" from the foreground process. So retain the checks of the current tty owner but migrate them to the point of calling tcsetpgrp() itself. 2020-07-27 00:55:00 +00:00
