flaws list)
TODO:
* verify that no sequence of API calls produces SIGSEGV.
That is, verify that mysql_stmt_init -> mysql_stmt_fetch is OK,
or mysql_stmt_prepare -> mysql_stmt_fetch_column is OK and sets
meaningful error.
* remove alloc_stmt_fields call
* revise stmt->state codes and statement states.
* there are other items in prepared statements 'to fix' document.
Done:
- cleanups and comments
- revision of prepared statement error codes.
- mysql_stmt_prepare is now can always be called (that is, you can reprepare
a statement)
- new implementation of mysql_stmt_close and fetch cancellation
include/errmsg.h:
- CR_NOT_ALL_PARAMS_BOUND - this error code wasn't used until now.
Apparently it was added in advance, but then interface of
mysql_stmt_bind_param changed. Now it's not possible to bind only some
parameters - either all or none of parameters are bound.
This error code is renamed to CR_PARAMS_NOT_BOUND
- CR_FETCH_CANCELLED - error code set on server side when fetch from
MYSQL_RES or MYSQL_STMT (in blocking mode) was cancelled because of
intercepting call to mysql_stmt_close
- CR_NO_DATA - this is proposed error code to return from
mysql_stmt_fetch_column if no row was fetched (by any type of fetch).
We always can fall back to CR_COMMANDS_OUT_OF_SYNC though.
Need reviewer's opinion on this one.
include/mysql.h:
- added unbuffered_fetch_owner member to MYSQL to point to MYSQL_RES
or MYSQL_STMT which is used to fetch result at the moment.
This is to be able to set CR_FETCH_CANCELLED error without fantoms.
- added unbuffered_fetch_cancelled boolean variable to MYSQL_STMT and
MYSQL_RES structures
- rename PREP_STMT_STATE -> enum enum_mysql_stmt_state
- members of MYSQL_STMT ordered by size.
- removed members of MYSQL_STMT: current_row, result_buffered,
last_fetched_column, last_fetched_buffer, query
- renamed members of MYSQL_STMT: param_buffers -> bind_param_done,
res_buffers -> bind_result_done
- now mysql_stmt_fetch calls stmt->read_row_func to read row either from
buffer or from network.
include/sql_common.h:
declaration for flush_use_result
libmysql/client_settings.h:
stmt_close declaration removed
libmysql/errmsg.c:
Error messages for changed and added error codes.
libmysql/libmysql.c:
Many changes:
- some unused variables removed
- cleanups
- better error reporting
- some function calls commented
- alloc_stmt_fields is now called right after execute, to not read
mysql->fields of some other statement
- new implementation of mysql_stmt_fetch - this is also with cursor
fetch in mind (to implement cursor fetch I'll just need to write
special read_row function for it, so this change will be local)
- implementation of fetch cancellation, including complete rewrite of
mysql_stmt_close
- now mysql_stmt_free_result doesn't free results of other statements.
sql-common/client.c:
- implementation of flush_use_result
- implementation of fetch cancellation
- changed behaviour of mysql_close in regard to mysql_stmt_close - now
mysql_close just set stmt->mysql to 0

Problem was that we checked for existing connection in stmt_close
and did not free(stmt) if it's closed (that didn't work well with
embedded)
I just added new flag to the stmt_close and now we check it instead
of connection

fixes to make mysql_change_user working in embedded library
Done clean-up in prep stmt API functions:
1) Removed some checks that were performed only in debug version
were making debug version more tolerable to user errors than
production (and thus caused problems for example masking some
bugs).
2) Also removed some other checks to make prep stmt API
consistent with the rest of C API (this also in line with
general politics - make checks in only those places where
errors are very common and hard to spot).
include/mysql.h:
Removed CHECK_EXTRA_ARGUMENTS define since it is no longer used
anywhere.
libmysql/libmysql.c:
Added check that will cause mysql_fetch() to bark then it is
used without calling mysql_execute() before.
Removed checks that were performed only in debug version and
caused problems since they were making debug version more
tolerable to user errors than production. Also removed some
other checks to make prep stmt API consistent in this regard
with the rest of C API (this also in line with general politics -
make checks in only those places where errors are very common
and hard to spot).
tests/client_test.c:
Updated tests to reflect removal of some checks in prep stmt API.
Removed lines that caused bug #2473 to pop up, should be added
as separate test with the fix for this bug.
Added test for bug#2248 "mysql_fetch without prior mysql_execute
hangs"
