Fixed (together with Guilhem) bugs in mysqlbinlog regarding --offset
Prefix addresses with 0x for easier comparisons of debug logs
Fixed problem where MySQL choosed index-read even if there would be a much better range on the same index
This fix changed some 'index' queries to 'range' queries in the test suite
Don't create 'dummy' WHERE clause for trivial WHERE clauses where we can remove the WHERE clause.
This fix removed of a lot of 'Using where' notes in the test suite.
Give NOTE instead of WARNING if table/function doesn't exists when using DROP IF EXISTS
Give NOTE instead of WARNING for safe field-type conversions
Easy to prevent crash, but the question was how to treat this case?
We ended up implementing the "global" SPs (i.e. with no associated
db), which were planned but left unresolved when SPs moved into dbs.
So now things like "call .p()" work too.
Mostly needed for Monty for him getting notion what needed for triggers
from new .FRM format.
Things to be done:
- Right placement of trigger's invocations
- Right handling of errors in triggers (including transaction rollback)
- Support for priviliges
- Right handling of DROP/RENAME table (hope that it will be handled automatically
with merging of .TRG into .FRM file)
- Saving/restoring some information critical for trigger creation and replication
with their definitions (e.g. sql_mode, creator, ...)
- Replication
Already has some known bugs so probably not for general review.
The description is not entirerly correct. The issue was follow-up errors
where the first error is not caught - in which case it's often a system
error with errcode < 1000 (which are mapped by default to 'HY000'). In this
case the error state is different from what was assumed in the execution
loop.
- 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.
Note: The following tests fails
- fulltext (Sergei has promised to fix)
- rpl_charset (Guilhem should fix)
- rpl_timezone (Dimitray has promised to fix)
Sanja needs to check out the calling of close_thread_tables() in sp_head.cc
It's not possible to quote the definition according to the current sql_mode
setting, so instead we use the setting stored with the SP (that's how it's
parsed anyway), and show this setting in the SHOW CREATE output.
Backpatching overwrote already backpatched instructions, which made it
skip the hpop instruction; possibly not only a problem for handlers,
but this is one known case when it happened.
Added new test cases for this, and adjusted old tests accordingly,
and new error codes and messages.
Fixed bugs in some tests (bug2673 and use test).
Added debug printing of instructions in SPs.
Phase 2: Make SPs belong to a DB, and use qualified names.
As a side effect, using USE in an SP is no longer allowed.
(It just doesn't work otherwise.)
