8 * Revision 1.7 2004/05/25 20:53:21 oetiker
9 * prevent small leak when resources are exhausted -- Mike Slifcak
11 * Revision 1.6 2004/05/25 20:51:49 oetiker
12 * Update displayed copyright messages to be consistent. -- Mike Slifcak
14 * Revision 1.5 2003/02/13 07:05:27 oetiker
15 * Find attached the patch I promised to send to you. Please note that there
16 * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
17 * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
18 * library is identical to librrd, but it contains support code for per-thread
19 * global variables currently used for error information only. This is similar
20 * to how errno per-thread variables are implemented. librrd_th must be linked
21 * alongside of libpthred
23 * There is also a new file "THREADS", holding some documentation.
25 * -- Peter Stamfest <peter@stamfest.at>
27 * Revision 1.4 2002/02/01 20:34:49 oetiker
28 * fixed version number and date/time
30 * Revision 1.3 2001/03/10 23:54:39 oetiker
31 * Support for COMPUTE data sources (CDEF data sources). Removes the RPN
32 * parser and calculator from rrd_graph and puts then in a new file,
33 * rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
34 * clean-up of aberrant behavior stuff, including a bug fix.
35 * Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
36 * -- Jake Brutlag <jakeb@corp.webtv.net>
