Logging facilities.
Logging facilities.
Two logging streams are supported: error log and info log. Additionally
libdbug may be used for debug information output.
ANSI C buffered I/O is used to perform logging.
Logging is performed via stdout/stder, so one can reopen them to point to
ordinary files. To initialize loggin environment log_init() must be called.
Rationale:
- no MYSQL_LOG as it has BIN mode, and not easy to fetch from sql_class.h
- no constructors/desctructors to make logging available all the time

/*
A multi-threaded application shall nicely work with signals.
This means it shall, first of all, shut down nicely on ``quit'' signals:
stop all running threads, cleanup and exit.
Note, that a thread can't be shut down nicely if it doesn't want to be.
That's why to perform clean shutdown, all threads consituting a process
must observe certain rules. Here we use the rules, described in Butenhof
book 'Programming with POSIX threads', namely:
- all user signals are handled in 'signal thread' in synchronous manner
(by means of sigwait). To guarantee that the signal thread is the only who
can receive user signals, all threads block them, and signal thread is
the only who calls sigwait() with an apporpriate sigmask.
To propogate a signal to the workers the signal thread sets
a variable, corresponding to the signal. Additionally the signal thread
sends each worker an internal signal (by means of pthread_kill) to kick it
out from possible blocking syscall, and possibly pthread_cond_signal if
some thread is blocked in pthread_cond_[timed]wait.
- a worker handles only internal 'kick' signal (the handler does nothing).
In case when a syscall returns 'EINTR' the worker checks all
signal-related variables and behaves accordingly.
Also these variables shall be checked from time to time in long
CPU-bounded operations, and before/after pthread_cond_wait. (It's supposed
that a worker thread either waits in a syscall/conditional variable, or
computes something.)
- to guarantee signal deliverence, there should be some kind of feedback,
e. g. all workers shall account in the signal thread Thread Repository and
unregister from it on exit.
Configuration reload (on SIGHUP) and thread timeouts/alarms can be handled
in manner, similar to ``quit'' signals.
