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.

979f72199f 32580: avoid indefinite wait in lockhistfile() by checking for lock file time stamp in the future 
Also change behavior of HIST_FCNTL_LOCK to use only fcntl() locking, rather
than applying both kinds of lock.

ff520d1b79 31823: add HISTORY_IGNORE parameter 
HISTORY_IGNORE defines a pattern to exclude matching lines in the internal
history from the HISTFILE at write time.

73ececfd01 31830: New feature for zshaddhistory hooks. 
If the first non-zero return status is 2, save the line on the
internal history list, but don't write it out.

d0fe73c5fb 31815: another fix for INCAPPENDHISTORY change. 
We need to save immediately if something is pushed on the history stack
to ensure we use the right file before popping.

8ffdf161c7 31797: to match documentation, avoid expanding history when there is neither a 
word nor an event designator

There are still a few cases where expansion is attempted even though the
documentation indicates it will not be, but in most of those cases the
expansion will fail.  The now-fixed case would fall back to default
expansion of the previous command.

6f195241f3 31794: further refinement to INCAPPENDHISTORY change. 
With SHAREHISTORY we should make sure the code behaves as it always
did, because it takes care about locking a file once for reading
and writing.

9345e57859 31793: Fix problem with non-interactive history.

e282fd8ecb 31750: fix for HISTREDUCEBLANKS option. 
Don't truncate line after marked words if there's more
non-white-space text, which is probably comments.

7c56d77184 30789: Add CONTINUE_ON_ERROR for old behaviour. 
New behaviour is for scripts to exit on error instead of returning
to top level and executing the next command.

3ccc3e4bdc Use the new gettempfile() function. 2004-10-21 00:33:50 +00:00
Wayne Davison
945a40f7e6 - Improved lockhistfile() to use the new gettempname() for a unique 
filename instead of a .PID suffix.
- Use bicat() to build the $HISTFILE.LOCK filename.
- Put the $HOST value into $HISTFILE.LOCK in addition to the PID.
 2004-10-18 19:07:30 +00:00
Wayne Davison
89eb92d8c2 - Added an arg to saveandpophiststack() to allow the caller to

Wayne Davison
3e7b092bc7 - pushhiststack() now takes a level value and remembers it. If it was 
the locallevel (instead of -1), the history list is marked to auto-pop
  on function exit.
- The saveandpophiststack() function now interprets a 0 arg as a request
  to do an auto-pop.
 2004-05-21 20:05:12 +00:00
Wayne Davison
e8eca2ee4b - Added functions to push and pop the current history list, allowing 
functions to more easily switch to their own private history.
- Changed the existing history push/pop code in savehistfile() (which
  uses a separate history buf to allow it to rewrite the on-disk
  version of the history file without disturbing the in-memory list).
