Guido van Rossum | ae94cf2 | 1998-05-08 21:52:55 +0000 | [diff] [blame] | 29 | 1998/04/28 (Sean Reifschneider) |
| 30 | - When facility not specified to syslog() method, use default from openlog() |
| 31 | (This is how it was claimed to work in the documentation) |
| 32 | - Potential resource leak of o_ident, now cleaned up in closelog() |
| 33 | - Minor comment accuracy fix. |
| 34 | |
Guido van Rossum | c1822a4 | 1995-10-11 16:15:28 +0000 | [diff] [blame] | 35 | 95/06/29 (Steve Clift) |
| 36 | - Changed arg parsing to use PyArg_ParseTuple. |
| 37 | - Added PyErr_Clear() call(s) where needed. |
| 38 | - Fix core dumps if user message contains format specifiers. |
| 39 | - Change openlog arg defaults to match normal syslog behaviour. |
| 40 | - Plug memory leak in openlog(). |
| 41 | - Fix setlogmask() to return previous mask value. |
