f3d6620f00 - Commit Derick's patch for allowing Zend to use regular libc memory 
- allocation functions. Mainly useful in conjunction with tools such as
- valgrind which enables us to find bugs we might not find with the
- current memory managers boundary protection.

138ef9a43e - Improve performance by inlining zend_ptr_stack_n_push(). var_args can 
usually not be inlined by compilers.

182e93ab6e - Add safe_pemalloc() 2004-07-20 21:55:57 +00:00

56f8195fe5 - Nuke empty_string. It is a reminanent from the time where RETURN_FALSE() 
used to return "" and not bool(false). It's not worth keeping it because
  STR_FREE() and zval_dtor() always have to check for it and it slows down
  the general case. In addition, it seems that empty_string has been abused
  quite a lot, and was used not only for setting zval's but generally in
  PHP code instead of "", which wasn't the intention. Last but not least,
  nuking empty_string should improve stability as I doubt every place
  correctly checked if they are not mistakenly erealloc()'ing it or
  calling efree() on it.
  NOTE: Some code is probably broken. Each extension maintainer should
  check and see that my changes are OK. Also, I haven't had time to touch
  PECL yet. Will try and do it tomorrow.

90bad130a9 MFZE1: If the size-operands of memset are constants, the compiler can turn them into fast inline code. So, instead of using ecalloc, we use emalloc + memset in macro form now. emalloc will not return NULL, so the chosen macro form is safe. This is not true for malloc(3). An inline function accomodates our needs here. Suggested by: http://www.mail-archive.com/dev%40httpd.apache.org/msg02492.html (Sascha) 2002-04-27 15:23:46 +00:00
