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 23:10:12 +08:00			`#RUN: %fish %s \| %filter-ctrlseqs`
Stop storing block_io in job_t Prior to this fix, a job would hold onto any IO redirections from its parent. For example: begin echo a end < file.txt The "echo a" job would hold a reference to the I/O redirection. The problem is that jobs then extend the life of pipes until the job is cleaned up. This can prevent pipes from closing, leading to hangs. Fix this by not storing the block IO; this ensures that jobs do not prolong the life of pipes. Fixes #6397 2019-12-12 08:34:20 +08:00
