f4c37a78b1 36265 plus FAQ: fix alias expansion after "function" 
Owing to interesting historical parsing, names after the first
were treated as command words so had non-global aliases expanded.
Add an FAQ note that use of the function keyword works around
other alias problems

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.

93e5234532 35643: Redirections after typeset assignments were broken. 2015-06-28 17:47:02 +01:00
Peter Stephenson
39b28980f3 various posts: Implement assignment parsing for typeset. 
Typeset assignments now work like raw assignments except
for no "+=" and no GLOB_ASSIGN.

Documented in typeset builtin doc and mentioned in release notes.

Tests to ensure basic sanity.

Enabled by default, can be turned off by "disable -r" with typeset
family of commands.

2d6569e590 35184: Additional case fix for 35168. 
Lexical analysis flags got screwed up after a "|", so we
didn't parse patterns properly, in particular those with parentheses.

Peter Stephenson
52aeb9aaeb 35168: Improve parsing of case patterns. 
"|" is now found properly by looking for words that come
from the lexical analyser, rather than hacking a pattern
returned in one dollop.

Update some completion functions that need extra quoting
as a result.

Add test for new parsing.

Update version number to 5.0.8-dev-3 because of wordcode
incompatibility.

4508d25710 34905: no parse error after keyboard interrupt. 
Handled generally, though only showing up in special nested
cases.

Also fix ZLE so it doesn't cancel the interrupt flag when
not actually returning from a local keymap.

da86d6b4f2 34485: More rationalisation for anonymous functions. 
Don't attempt to treat as "simple" case as there are too many
hidden problems.

Pull out some post-execution functions to a common case in
execcmd().

cfd91eac07 Rearrange context saving. 
Variables are now associated with the module that declares them, being
initialised and saved/restored there.  However, as many variables are
used for communication between modules, many of them are set in multiple
places, so the assignment is ambiguous.

c0d01a6fe0 Fix command substitutions to parse contents as they are read in. 
Do this by refactoring misnamed lexsave()/lexrestore() to allow
continuity of history and input.

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.

31750795fe 33345: fix anonymous function complex command handling. 
Longstanding problem caused simple anonymous function incorrectly to
reset the overall "complext" state, causing wordcode to be diverted
into execsimple(), which caused a crash 'cos ist wasn't simple.

9d47e8398d 32609: [[ $var ]] behaves as [[ -n $var ]] for bash/ksh compatibility 
Also restore ksh [ -t ] compatibility when POSIX_BUILTINS is not set, and
allow operators defined by modules to be called with no arguments, although
this affects only runtime interpretation, not parsing.
