- The io cache flag seek_not_done was not set properly in the

  desipite an invalid file handle.
- Added a test in reinit_io_cache to ensure we have a valid file 
  handle before setting seek_not_done flag.

          (back-port to 4.0)

Socket timeouts in client library were used only on Windows.
Additionally, in 4.0 write operations erroneously set read timeout.

The solution is to use socket timeouts in client library on all
systems were they are supported, and to differentiate between read
and write timeouts.

No test case is provided because it is impossible to simulate network
failure in current test suite.


include/violite.h:
  Add argument to vio_timeout() to determine which timeout should be set:
  for read (false) or for write (true).
libmysqld/lib_vio.c:
  Add argument to vio_timeout() to determine which timeout should be set:
  for read (false) or for write (true).
sql/net_serv.cc:
  Add argument to vio_timeout() to determine which timeout should be set:
  for read (false) or for write (true).
vio/viosocket.c:
  Add argument to vio_timeout() to determine which timeout should be set:
  for read (false) or for write (true).
  Implement socket timeouts on POSIX systems.

- Fix my_read/my_write to handle return values from read/write correctly
- Add debugging 'deprecated function' warning to my_lread/my_lwrite
- Add debugging 'error, read/write interrupt not handled' warning to my_quick_read/my_quick_write

There is no test case associated with these changes.  However, this is a conservative change,
and no repeatable test case is available.


mysys/my_lread.c:
  Warn about using deprecated function.
mysys/my_lwrite.c:

mysys/my_pread.c:

	event' from master"

Since there is no repeatable test case, and this is obviously wrong, this is
the most conservative change that might possibly work.  

The syscall  read()  wasn't checked for a negative return value for an
interrupted read.  The kernel  sys_read()  returns -EINTR, and the "library" 
layer maps that to return value of -1 and sets  errno  to EINTR.  It's 
impossible (on Linux) for  read()  to set errno EINTR without the return 
value being -1 .

So, if we're checking for EINTR behavior, we should not require that the
return value be zero.


mysys/my_read.c:
  The read() syscall should check for negative one, since that (usually) signals
  errors (like being interrupted) and zero (usually) signals end-of-file .

Fixed a possible problem with reading of dynamic records
when a write cache is active. The cache must be flushed
whenever a part of the file in the write cache is to be 
read.

Added a read optimization to _mi_read_dynamic_record().

No test case. This was a hypothetical but existing problem.


myisam/mi_dynrec.c:
  Bug#20719 - Reading dynamic records with write buffer could fail
  
  Fixed a possible problem with reading of dynamic records
  when a write cache is active. The cache must be flushed
  whenever a part of the file in the write cache is to be 
  read. This must be done before the read of the header
  and before the read of the rest block.
  
  Renamed the 'flag' and 'skipp_deleted_blocks' variables.
  
  Added a read optimization to _mi_read_dynamic_record()
  that was present in _mi_read_rnd_dynamic_record() already.
  After _mi_get_block_info() we have some bytes of the record
  in the header buffer already. No need to read them again.

have a better test (and so this should be null-merged there).

ALSO!  Make it so that it accepts NPTL as a valid _equivalent_ implementation.

On exactly-sized Strings, the String::c_ptr() function peeked beyond the
end of the buffer, possibly into unititialized space to see whether the 
buffer was NUL-terminated.

In a place that did peek improperly, we now use a c_ptr_safe() function, 
which doesn't peek where it shouldn't.


client/sql_string.h:
  Back-port String::c_ptr_safe().
sql/item_func.h:
  Describe side-effect behavior.
sql/item_strfunc.cc:
  Use the "_safe" version of c_ptr to avoid looking for a terminating 
  NUL character outside the initialized memory area.  Valgrind hates it 
  when one does that, and it theoretically could lead to a SEGV.
sql/sql_string.h:
  Back-port String::c_ptr_safe().

It was possible that fetching a record by an exact key value 
(including the record pointer) could return a record with a 
different key value. This happened only if a concurrent insert 
added a record with the searched key value after the fetching 
statement locked the table for read.

The search succeded on the key value, but the record was
rejected as it was past the file length that was remembered
at start of the fetching statement. With other words it was 
rejected as being a concurrently inserted record.

The action to recover from this problem was to fetch the 
record that is pointed at by the next key of the index. 
This was repeated until a record below the file length was 
found.

I do now avoid this loop if an exact match was searched. 
If this match is beyond the file length, it is now treated 
as "key not found". There cannot be another key with the 
same record pointer.


myisam/mi_rkey.c:
  Bug#14400 - Query joins wrong rows from table which is subject of "concurrent insert"
  Added a check for exact key match before searching for
  the next key that was not concurrently inserted. If an
  exact key match finds a concurrently inserted row, this
  must be treated as "key not found".
