e97722e495 Fix for BUG#2083
"EE_ error codes (EE_DELETE, EE_WRITE) end up in the binlog, making slave stop".
The problem was that during execution of the command on the master, an error
can occur (for example, not space left on device, then mysqld waits and when
there is space it completes successfully: so finally it worked but the error
EE_WRITE remains in thd->net.last_errno and thd->net.last_error).
To know if finally the command succeeded, we test the 'error' variable in
every place, and if it shows no failure we reset thd->net.last_err* using
the function THD::clear_error() which is backported from 4.1.
A new test to see if now only real errors get to the binlog (note: the test
uses "rm").

Also a bit of memory free/alloc saving in log_event.cc (do not free the whole
mem_root after every query in the slave SQL thread: we can keep the initial
block of it; which will be freed when the thread terminates).


sql/log_event.cc:
  In the slave SQL thread, it's a waste to free the initial block of the mem_root
  after every query. We can instead keep it. It will be freed when the thread
  terminates (in THD::~THD()).
sql/sql_acl.cc:
  clear the error in thd->net.last_errno as there was no error
sql/sql_base.cc:
  clear the error in thd->net.last_errno as there was no error

c545b02645 Fix for Bug #1952
"SHOW TABLE STATUS very slow w/large number of tables"
Replaced old algorithm which were used in my_dir() and stored
all information about directory entries in one chunk of memory
with new one which stores file names and MY_STAT structures in
separate memroot, so now we don't need to copy this data during
reallocation of dir_entry array.


include/my_dir.h:
  Changed mystat member of FILEINFO structure to pointer since 
  this prevents unneeded memory allocation and initialization.
  Added comment about new hidden members of MY_DIR structure.
mysys/my_lib.c:
  Replaced old algorithm in my_dir() which stored all information
  about directory entries in one chunk of memory with new one 
  which stores file names and MY_STAT structures in separate
  memroot. Now we don't copy this data during reallocation of 
  array with FILEINFO structures.
  Also tuned sizes of memory chunks during first-other
  reallocations (we suppose that we either have < 100 files 
  in the directory or > 1000 of them).
sql/sql_show.cc:
  Updated only place in code where mystat member
  of FILEINFO structure is used.

9a1cb59cd7 Create PID file with O_TRUNC, so that it is emptied before it is written to.
Otherwise, if the previous run ended with a crash, and the PID was 1234,
and you have rebooted the machine and the new PID is 99 then in the PID
file you will have 9934.
Note: users of mysqld_safe did not have the problem because this script
deletes the PID file before starting mysqld.

a50761a565 Fix for BUG#2045 "Sending SIGHUP to mysqld crashes it if running with --log-bin".
The constructor of Rotate_log_event used when we are rotating our binlog or
relay log, should not assume that there is a nonzero THD available.
For example, when we are reacting to SIGHUP, the THD is 0.
In fact we don't need to use the THD in this constructor;
we can do like for Stop_log_event, and use the minimal Log_event
constructor.
If we were allowed to put Unix-specific commands in the testsuite,
I'd add a test for this (<sigh>).


sql/log.cc:
  A comment to warn that thd can be 0.
  The part about LOG_EVENT_FORCED_ROTATE_F is just to avoid segfault;
  this flag is already removed in 4.1 anyway.
sql/log_event.cc:
  A comment.
sql/log_event.h:
  The constructor of Rotate_log_event used when we are rotating our binlog or
  relay log, should not assume that there is a nonzero THD available.
  For example, when we are reacting to SIGHUP, the THD is 0.
  In fact we don't need to use the THD in this constructor;
  we can do like for Stop_log_event, and use the minimal Log_event
  constructor.
  This fixes BUG#2045 
  "Sending SIGHUP to mysqld crashes it if running with --log-bin"
