* it is possible for some of the real time signals to be used by glibc,Andrew Tridgell2003-03-281-1/+4
| | | | | which then changes SIGRTMIN. It is also possible for bash to leave some real time signals blocked at startup. This fixes both problems.

* The big character set handling changeover!Andrew Tridgell2001-07-041-1/+1
| | | | | | | This commit gets rid of all our old codepage handling and replaces it with iconv. All internal strings in Samba are now in "unix" charset, which may be multi-byte. See internals.doc and my posting to samba-technical for a more complete explanation.

| | | | | | | | | | | | | smbd/notify_kernel.c: This code was wrong I believe. It was structured to only return a changenotify event on being called from timeout processing (t != 0). The kernel changenotify events should fire on *asynchronous* processing (EINTR return from select caused by the realtime signal delivery) with t == 0. Reported by Juergen Hasch (Hasch@t-online.de). ANDREW PLEASE CHECK THIS ! Currently the hash style changenotify is done on async processing as well as timeout processing. As this is expensive we may want to revisit doing this and maybe set it to fire only on timeout processing. Jeremy.

handling in Samba. This was needed due to several limitations and races in the previous code - as a side effect the new code is much cleaner :) in summary: - changed sys_select() to avoid a signal/select race condition. It is a rare race but once we have signals doing notification and oplocks it is important. - changed our main processing loop to take advantage of the new sys_select semantics - split the notify code into implementaion dependent and general parts. Added the following structure that defines an implementation: struct cnotify_fns { void * (*register_notify)(connection_struct *conn, char *path, uint32 flags); BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t); void (*remove_notify)(void *data); }; then I wrote two implementations, one using hash/poll (like our old code) and the other using the new Linux kernel change notify. It should be easy to add other change notify implementations by creating a sructure of the above type. - fixed a bug in change notify where we were returning the wrong error code. - rewrote the core change notify code to be much simpler - moved to real-time signals for leases and change notify Amazingly, it all seems to work. I was very surprised!
