Putting initialization into .cc will reduce compiler's abilities
to optimize this constant away.
Defines are not OK as they bloat global namespace.
Looking for a way to declare an efficient named constant in reduced
namespace (i. e. in a class).
Let's try enums: normally they should be implicitly casted to int.
Let's see if we really have a compiler which won't do that.
This was a customer request for to get the XP Logo Certification.
Note for LenZ:
Adding to the project libmysqld.dsp the file libmysqld.rc at compilation time will be created
the libmysqld.res and this linked. For every release edit the libmysqld.rc
version number.
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
state and has no additional locking wisdom.
Lot's of it are to be rewritten.
required autotools macro written and deployed in all apropriate Makefile.ams.
Use cases checked:
- linux, standard location of zlib, no ndb
- linux, standard locatoin of zlib, with ndb
- linux, non-standard location of zlib, no ndb
- hpux11, use of bundled zlib, no ndb
The only non-checked case is non-standard location of zlib (or use of bundled
zlib) + ndb. I wasn't able to check it as ndb/ just won't compile on beasts
like AIX52 or HPUX11, where such a check is possible. It didn't compile
there before as these systems dont't have installed zlib, so nothing got broken ;)
#4700 (Unsigned value returned as signed)
just no appropriate checking
#4701 (Errors returned earlier than expected)
all errors returned from send_command()
#4702 (Result isn't freed properly if there's no retrieval)
flush_use_result has only 'client' version and should
be made 'virtual'
work (prepared statements)" and after-review fixes:
- str_to_TIME renamed to str_to_datetime to pair with str_to_time
- functions str_to_time and str_to_TIME moved to sql-common
- send_data_str now supports MYSQL_TYPE_TIME, MYSQL_TIME_DATE,
MYSQL_TIME_DATETIME types of user input buffers.
- few more comments in the client library
- a test case added.
Added basic per-thread time zone functionality (based on public
domain elsie-code). Now user can select current time zone
(from the list of time zones described in system tables).
All NOW-like functions honor this time zone, values of TIMESTAMP
type are interpreted as values in this time zone, so now
our TIMESTAMP type behaves similar to Oracle's TIMESTAMP WITH
LOCAL TIME ZONE (or proper PostgresSQL type).
WL#1266 "CONVERT_TZ() - basic time with time zone conversion
function".
Fixed problems described in Bug #2336 (Different number of warnings
when inserting bad datetime as string or as number). This required
reworking of datetime realted warning hadling (they now generated
at Field object level not in conversion functions).
Optimization: Now Field class descendants use table->in_use member
instead of current_thd macro.
Ensured that all projects compile
Removed compiler warnings
Better setting of server_version variable.
Fix that make_win_src_distribution creates the privilege tables.
Fixed bugs in group_concat with ORDER BY and DISTINCT (Bugs #2695, #3381 and #3319)
Fixed crash when doing rollback in slave and the io thread catched up with the sql thread
Set locked_in_memory properly
now mysql_server_init is called from mysql_init with fake parameters
mysql_once_init code included to mysql_server_init.
embedded-specific initialization is in init_embedded_server function
Cleaned up (and disabled part of) date/time/datetime format patch. One can't anymore change default read/write date/time/formats.
This is becasue the non standard datetime formats can't be compared as strings and MySQL does still a lot of datetime comparisons as strings
Changed flag argument to str_to_TIME() and get_date() from bool to uint
Removed THD from str_to_xxxx functions and Item class.
Fixed core dump when doing --print-defaults
Move some common string functions to strfunc.cc
Dates as strings are now of type my_charset_bin instead of default_charset()
Introduce IDENT_QUOTED to not have to create an extra copy of simple identifiers (all chars < 128)
Removed xxx_FORMAT_TYPE enums and replaced them with the old TIMESTAMP_xxx enums
Renamed some TIMESTAMP_xxx enums to more appropriate names
Use defines instead of integers for date/time/datetime string lengths
Added to build system and use the new my_strtoll10() function.
handling of init-file option added to embedded library
main problem was killing of output (resulting recordsets etc)
i added checks for empty output in Protocol:: methods
better solution could be special Protocol_nul class to redirect
results to nowhere
WL#604 Privileges in embedded library
code added to check privileges in embedded library
NO_EMBEDDED_ACCESS_CHECKS macros inserted in code so we can exclude
access-checking parts. Actually we now can exclude these parts from
standalone server as well. Do we need it?
Access checks are disabled in embedded server by default. One should
edit libmysqld/Makefile manually to get this working.
We definitely need the separate configure for embedded server
null_string wasn't known in libmysqld/lib_sql.cc, that caused compiler's error
i put the declaration of the null_string in mysql_priv.h and renamed it
to my_null_string to reduce the probability of name's intersections
embedded library
some dirty places cleaned:
uint removed from mysql.h as Miguel suggested
empty_string renamed as my_empty_string to get rid of name's intersections
using embedded library
embedded library
I decided to get rid of #define mysql_some_function in mysql.h
It puzzles users and makes problems with dynamic libraries
Finally, there are only two functions left, that are covered with
the #define-s and it won't hurt performance at all
Prepared statements in embedded server
Several changes in library code with two goals:
to make mysql_prepare_stmt working in embedded server
to get rid of #define mysql_interface_func mysql->methods->interface_func
in user's interface
- removed "-traditional-cpp" from the darwin6 compile flags, as it broke
compilation with gcc-3.3 on Mac OS X and does not seem to be required
in general.
- make sure to link libmysqld/examples/mysqltest.c with a C++ compiler,
as the embedded server library (libmysqld.a) includes C++ code. This
broke compilation with non-gcc compilers.
mysql_fetch_length fixed for embedded library. Now data length is stored
before the data. Pointers in row still points to the data so you have to
get *(uint*)(data_ptr - sizeof(uint)) to get data length
