1cdaf10c45 - Run hooks in background - don't block waiting for them to finish. 
- Keep all hooks we're running in a global list, so we can report when
  they finish and also report when they are running for too long.

28df1f238a For some setups sending data in 128kB chunks makes communication very slow. No

471bb09914 The 'size' variable is there to limit how many bytes we want to copy from 
'addr'. It is very likely that size of 'addr' is larger than 'size', so checking
strlcpy() return value is bogus.

- Don't exit on errors if not requested.
- Don't keep configuration in global variable, but allocate memory for
  configuration.
- Call yyrestart() before yyparse() so that on error in configuration file
  we will start from the begining next time and not from the place we left of.

524840d8d0 Problem with assertion is that it logs on stderr. Add two macros: 
PJDLOG_ASSERT() and PJDLOG_VERIFY() that will check the given condition
and log the problem where appropriate. The difference between those
two is that PJDLOG_VERIFY() always work and PJDLOG_ASSERT() can be
turned off by defining NDEBUG.

9fab3c1b94 Remove macros that are not really needed. The idea was to have them in case 
we grow more descriptors, but I'll reconsider readding them once we get there.

Passing (a = b) expression to FD_ISSET() is bad idea, as FD_ISSET() evaluates
its argument twice.

wait using select(). Very complex, but I know no other way to define

32115b105a Please welcome HAST - Highly Avalable Storage. 
HAST allows to transparently store data on two physically separated machines
connected over the TCP/IP network. HAST works in Primary-Secondary
(Master-Backup, Master-Slave) configuration, which means that only one of the
cluster nodes can be active at any given time. Only Primary node is able to
handle I/O requests to HAST-managed devices. Currently HAST is limited to two
cluster nodes in total.

HAST operates on block level - it provides disk-like devices in /dev/hast/
directory for use by file systems and/or applications. Working on block level
makes it transparent for file systems and applications. There in no difference
between using HAST-provided device and raw disk, partition, etc. All of them
are just regular GEOM providers in FreeBSD.

For more information please consult hastd(8), hastctl(8) and hast.conf(5)
manual pages, as well as http://wiki.FreeBSD.org/HAST.
