Remove usage of my_tempnam() (not safe function)
if( -> if ( and while( to while (
Produce warnings of wrong cast of strings to signed/unsigned.
Don't block not resolved IP's if DNS server is down (Bug #8467)
Fix compiler problems with MinGW (Bug #8872)
The patch implements the idea suggested by Olaf van der Spek in
thread "Client: many small reads?" (internals@lists.mysql.com).
Now small reads performed by the client library are buffered.
The buffering gives up to 2 times speedup when retrieving
one-column tables.
Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root
Bug #5492
"set @@session.read_rnd_buffer_size=33554432" crashes server on query
1. added warning comments for uint3korr (need one more byte allocated)
2. unsigned long in uint3korr was replaced by unsigned int to
avoid problems on 64-bits platforms
3. shorten warning comments in init_rr_cache in sql/records.cc
Use 'mysqltest' as test database instead of test_$1 or test1,test2 to not accidently delete an important database
Safety fix for mailformed MERGE files
flag is sent to server with placeholder types.
There were no need to extend the protocol as one additional byte
was reserved for placeholder code, when placeholder code is in range 0-255.
So this byte is now used for flags. Post-review fixes added.
This ensures that my_file_info takes this the max number of files into account and one can now use --open-files-limit on windows to increase number of used files up to 2048
mysql_server_init() now returns error code if something went wrong (Bug #2062)
Don't use my_fopen() when reading symlink information as this may cause problems when a lot of files are opened.
Free thread keys with pthread_key_delete() instead of relying on automatic free. (Bug #2062)
Fixed bug in UNION statement with alias '*'. (Bug #1249)
Fixed a bug in DELETE ... ORDER BY ... LIMIT where the rows where not deleted in the proper order. (Bug #1024).
FOUND_ROWS() could return incorrect number of rows after a query with an impossible WHERE condition.
HOW DATABASES doesn't anymore show .sym files (on windows) that doesn't point to a valid directory. (Bug #1385)
