553ff601b7 optimise: embed ^A and ^M inside the default PS1 string 2008-12-13 17:09:45 +00:00
tg
31d1499219 * back out almost all of the memory allocator related changes, as aalloc 
was hard to type and hard to fix, galloc is also hard to fix, and some
  things I learned will probably improve things more but make me use the
  original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here

a19bf7253a * sh.h: note that file descriptors SHALL be <100 
* syn.c: fix bashiop-4 regression test; failed due to me using a
  simple string when a wdstring was expected, sorry; the new code
  assumes file descriptors take up a maximum of two characters

ef5a465acd fix botched testcase from 10049352E9F5DBF7056 - check.pl offers

330948eafd add a test case for the recursion limit fix 2008-12-02 12:48:16 +00:00
tg
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.

c0703f5f26 if MKSH_SMALL and HAVE_ARC4RANDOM, there is no need to use rand()/srand(3) 
ever, since MKSH_SMALL is not required to be as close to compatibility as
normal/generic shells; we can also get rid of time(3) calls

d97691ca61 by the principle of the working tree, we cannot enable aalloc as of now. 
damn, pointers in C are so uselessly complicated… in asm it’s much easier

90e8e7ea72 rewrite the cookie logic… while this is better than previously, 
we still have issues:

d8bc1cf161 thread-safety in the atexit function, justin case 2008-11-15 07:59:46 +00:00
tg
24a23d52d8 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
