Revision history:
|
|
|
|
2010/04/20 (Sean Reifschneider)
|
|
- Use basename(sys.argv[0]) for the default "ident".
|
|
- Arguments to openlog() are now keyword args and are all optional.
|
|
- syslog() calls openlog() if it hasn't already been called.
|
|
|
|
1998/04/28 (Sean Reifschneider)
|
|
- When facility not specified to syslog() method, use default from openlog()
|
|
(This is how it was claimed to work in the documentation)
|
|
- Potential resource leak of o_ident, now cleaned up in closelog()
|
|
- Minor comment accuracy fix.
|
|
|
|
95/06/29 (Steve Clift)
|
|
- Changed arg parsing to use PyArg_ParseTuple.
|
|
- Added PyErr_Clear() call(s) where needed.
|
|
- Fix core dumps if user message contains format specifiers.
|
|
- Change openlog arg defaults to match normal syslog behavior.
|
|
- Plug memory leak in openlog().
|
|
- Fix setlogmask() to return previous mask value.
|
|
