97d4bdbc7e 41590 modified as 41595: make ERR_RETURN more logical.
It now operates separately at each function depth.

To keep ERR_EXIT global, make the noerrexit variable usd bit flags.

Extend tests.

ddb8675901 posted but has not shown up: fix fd problem in subshell.
Record fd's that have been saved in fdtable and if the shell
forks close them as they will never be restored.

d7110d8f01 41012: Fix premature exit from nested function in EXIT trap.

immediately.

8b5102ccf5 40933: Ensure we get job text in sourced files.
This was turned off explicitly as it was assumed not to be needed,

64559abc1f 40796: MAGIC_EQUAL_SUBST not needed with parsed assignment.
If typeset family builtins are recognised as keywords then the value

magic behaviour, even if the option is set.

33799ae2b0 40335: More care with autoload function path.
If doing "autoload -X", the path present might actually be location

47b7f2adef unposted: more care with shell function filename.
When updating shfunc structure to change filename we should be
careful to free whatever's there already, we may now be the
directory in which to find the function definition.  After loading
the field contains the full name of the file.

f26d1ba6b0 Add features associated with autoloading a function using an absolute
path.

-d defaults to normal fpath

-r remembers the path without actually loading.  May be combined with -d.

-R does the same but it's an error if not found

-X can now take a directory path: this is used to output not yet loaded
functions that have an associated path.

9958684574 36022 fix bug that some loop constructs could not be interrupted, revise signal queueing
There are two underlying ideas here:  (1) Keeping signals queued around
anything that's doing memory management (including push/pop of the heap)
has become crucial.  (2) Anytime the shell is going to run a command, be
it buitin or external, it must be both safe and necessary to process any
queued signals, so that the apparent order of signal arrival and command
execution is preserved.

d067ebcacd 33876: etc.: Separate errors and keyboards interrupts
Combination of 12 commits from interrupt_abort branch.

Basic strategy is to introduce bits to errflag and to set and
reset them separately.

Remove interrupt status on return to main keymap.

Turn off ERRFLAG_INT for always block.

Restore bit thereafter: we probably need a new variable in order
to allow user interrupts to be reset in the always block.

Add TRY_BLOCK_INTERRUPT

This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too.

Ensure propagation of SIGINT from exited job.

If received by foreground job, shell uses ERRFLAG_INT, not
ERRFLAG_ERROR, to set the new state.

Reset errflag before precmd()

Add always block in _main_completion to fix ZLS_COLORS

Ensures we get the right state of $ZLS_COLORS at the end of _main_complete
even if there's an interrupt.  However, the "right state" is a bit messy
as it depends on styles.

7abd611a23 33614 (based on RedHat BZ-978613): signal safety when updating global state in execshfunc() 2014-11-06 10:50:20 -08:00
Peter Stephenson
023c2236e1 Treat exec from subshell as if forked
This removes weird behaviour when optimising the last command.
In particular SHLVL is correct from a subshell executed as the last
command.

b4f7ccecd9 33531 with additions: retain status of exited background jobs.
Add linked list of unwaited-for background jobs.
Truncate at value of _SC_CHILD_MAX discarding oldest.
Remove old lastpid_status mechanism for latest exited process only.
Slightly tighten safety of permanently allocated linked lists so
that this doesn't compromise signal handling.

c98cbe25d2 31919: fix deadlock when a shell builtin with a multio redirection is used on the left side of a pipeline
Make sure stdin/out/err file descriptors are closed for the multio copy
process, which means not re-using those descriptors after they are closed
and marked FDT_UNUSED in fdtable[].  For completeness, initialize their
fdtable[] state to FDT_EXTERNAL.

8c37e6f077 30272 (tweaked): most failures of fork() cause non-interactive shells to
