48ee7c736f (oops!) Free str to prevent memory leak. 2015-01-24 06:29:35 -08:00
Fish (David B. Trout)
26a1f86d7f PTT facility enhancements: 
1. Expand trace class to 64-bits.
2. Predefined convenience macros.
3. Expand trace message to 18 characters.
4. Use convenience macros where possible.

This commit is mostly in preparation for upcoming LCS debugging via PTT facility enhancements to help debug Issue #43 (which is a race condition and thus timing dependent, thus PTT debugging rather than logmsg debugging), but I tried to design it to make it easier for other modules (e.g. QETH) to also transition away from logmsg debugging to debugging via PTT facilty instead.

0e0481ffb8 HTHREADS / PTTRACE rework: refer to README.PTT for details. 
Note: this is the first (i.e. part 2a) of Part 2 of the locking/threading rework effort: hthreads restructuring.  Part 2b will be the hthreads.c code necessary to detect threads exiting while still holding locks (i.e. abandoned locks).

Fish (David B. Trout)
7c527a5fa2 Improved lock handling Part 1: better error reporting. 
Maintain lock ownership and report who owns the lock when an obtain_lock fails.

Part 2 will be the maintaining of a locks list and automatic reporting of abandoned locks (threads exiting while holding a lock(s)).

Part 3 will be adding support for Robust Mutexes, including to fthreads.

b9db83fa68 The support for Hercules variables causes random segment exceptions, 
often after the operating system has been started.  Thus the current
implementation does not "work".

Disable setenv() on unix when pthreads is active (which it is as soon
as a CPU is defined).  The change sets a mark on the wall over in pttrace.c
and refuses setenv() when that mark is set.  Read comments in hscutl.c
if you disagree.

This should probably also be done on Windows, but I shall leave that
to those who are competent on that platform.

The "fix" is nontrivial.

59cee637c1 Remove FishHang crap from Hercules 
FishHang was useful during development of fthreads but has not been needed for so many years and so has FINALLY been deleted. Sorry it took me so long to do it.

Use "secure" forms for some functions for windows. sprintf changed to MSGBUF embedded snprintf or snprintf_s to prevent buffer overruns.
