07541b6abf WL#1365: Implement definer's rights execution of stored procedures. 
(Also put the hostpart back in the definer column.)

7a20e5282e In order to make ALTER PROCEDURE|FUNCTION work correctly, and in general to 
make characteristics (and SHOW) work right, we had to separate the old
definition blob in the mysql.proc table into separate fields for parameters,
return type, and body, and handle the characteristics (like SQL SECURITY)
separately... and then reassemble the CREATE string for parsing, of course.
This is rather ugly, mostly the parser bit. (Hopefully that will be better
with the new parser.)

b27e9d6052 WL#1363: Update the mysql.proc table and add new fields. 
Also made the parsing and handling of SP characteristics
more general and extendable, and added a few ch:istics.

689bb84f72 WL#962: Added simple, read-only, non-scrolling, asensitive cursors in SPs, using the 
(updated) Protocol_cursor class.
Also did some bug fixes.

e8634f80bd Check that a FUNCTION contains RETURN and that we actually get a return value. 2003-10-03 17:38:12 +02:00

04f0570fe8 Implemented SP CONDITIONs and HANDLERs, with the extension of handling 
MySQL error codes as well.
(No UNDO HANDLERs yet, and no SIGNAL or RESIGNAL.)
WL#850

7a7f3c13d4 Adopt to the introduction of a separate CLIENT_MULTI_RESULTS flag. 2003-08-27 17:04:33 +02:00

c908b555ff Fixed the old kludge for pre-loading functions and made it more efficient 
using a hash table instead (and made it work with lex pointers).
Some additional code cleanup too.

6d225437ed Code cleanup (and moved sp cache to separate file). 2003-07-03 15:58:37 +02:00

4006e95808 Bugfixes for the sp_head memroot stuff. 2003-07-01 17:19:48 +02:00
pem@mysql.com
9f14ae7516 sp_head now has its own mem_root (WL#961). 
Also fixed some difficult memory leaks that became apparent
in this task.

6c85c6aa6a Post-fix of bug #302 fix. 
Fixed bug #320.
Some new tests and cosmetic changes.
Another strcasecmp() replaced.

a4e065920b Made multiple queries (SELECT without INTO) work in SPs. 
This included bug fixes in the 4.1 protocol (actually send and receive the
server_status flags).

1fc3582b7d Got rid of the last unecessary Item_strings. 2003-04-03 16:00:09 +02:00

c673fcb813 Getting rid of lots of memory leaks (but not quite all of them yet, 
some will go away when temporary code is replaced).

12f771d9e7 Improved error handling regarding SPs (with info like names etc in the output). 
Disabled queries in FUNCTIONs.
 2003-03-05 19:45:17 +01:00
pem@mysql.com
8049daf202 Made FUNCTIONs work in insert and select queries, as well as nested function invocations. 
Had to add a cahing mechanism which is in parts an ugly kludge, but it will be
reworked once the real SP caching is implemented.

ca2e77ca7a Made stored FUNCTION invokation work almost always. Still buggy and unstable, and 
various known problems, but good enough for a checkpoint commit.

d8c75ec8aa Most of the groundwork for sprint task 729 (implement FUNCTIONs). 
Expanded the mysql.proc table, reworked the find/create/drop functions
completely, added new functions for FUNCTIONs (lotta functions here :),
got rid of some unnecessary use of Item_strings while at it. Extended
the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs
coexist with UDFs.
Can now CREATE and DROP FUNCTIONs. Invoking yet to come...

58d3dda33f Added parsing of CASE (both generic and "simple"). 2002-12-17 10:01:52 +01:00

b1593c9a69 Fixed the broken backpatching implementation. 
Implemented IF-THEN-ELSE.

77b671f594 Moved create/find/drop functions to a separate files (sp.cc,sp.h). 
Fixed backpatching of forward jumps.
Implemented LOOP, WHILE, REPEAT (temporarily known as SPREPEAT).

Known bug: Expression evaluation still not quite ok (e.g. "x > 0"),
which is why IF and CASE is not yet implemented.

f0137bcd68 Fixed bugs in the parameter evaluation and modified the execution engine 
for better jump support. Some flow control support added too (but not
complete).

aae07a4d45 Simplistic, experimental framework for Stored Procedures (SPs). 
Implements creation and dropping of PROCEDUREs, IN, OUT, and INOUT parameters,
single-statement procedures, rudimentary multi-statement (begin-end) prodedures
(when the client can handle it), and local variables.
Missing most of the embedded SQL language, all attributes, FUNCTIONs, error handling,
reparses procedures at each call (no caching), etc, etc.
Certainly buggy too, but procedures can actually be created and called....
