add a test case for the recursion limit fix
2008-12-02 12:48:16 +00:00
4897682502
Alias expansion has a recursion check which tries to break the cycle if
...
encountered. However, when reading end of input, the source type is set
to SEOF while popping, whereas the recursion check code only checks for
an SALIAS type.
Fix: add a new SF_HASALIAS flag; change u.tblp from being valid if type
is SALIAS to being valid if SF_HASALIAS is set; set SF_HASALIAS for the
created SALIAS sources; set SF_HASALIAS and u.tblp when creating SALIAS
whose next is SEOF on the SEOF source as well.

add plugs for thread-safety, requested by Jonathan Schleifer
...
example:
#define AALLOC_THREAD_ENTER(ap) @synchronized(aalloc_guard) {
#define AALLOC_THREAD_LEAVE(ap) }
notes:
• you must declare and define eventual guard objects yourself
• while there will not be any direct “return” calls inside the
locked area, AALLOC_ABORT and AALLOC_WARN may be called
• AALLOC_RANDOM does not need to be thread-safe, but malloc
and free should be; if “ap” is used for locking, all functions
called must be thread-safe though
