a88415cbf7 36026: zero freed pointers in zftp cleanup_() in case the module is re-loaded after unloading 2015-08-09 16:13:52 -07:00
Barton E. Schaefer
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.

cba1d41ffc 2037: ${functions[foo]} shouldn't be unmetafied. 
When passed back from the parameter-specific "get" handler it's
still in the shell's internals, so remains metafied.

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

as a result.

Add test for new parsing.

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