Evan Miller 0f017883f6 Merge pull request #33 from evanmiller/remove-dmalloc 
Remove references to dmalloc
 2020-08-20 15:22:17 -04:00
Evan Miller 90ee7bfcb5 Remove references to dmalloc 
There are more modern tools for memory debugging, get rid of DMALLOC
crap in the source code.

I've left one reference in backend.c to prevent a merge conflict but
this can be removed later.

Evan Miller 452cd29343 Get rid of more static memory 
* Replace backend_is_init (formerly is_init) with relationships_table

* Remove deprecated functions that used static variables

* Move static "bound" variable to MdbHandle as relationships_values
 2020-08-20 08:47:13 -04:00
Evan Miller 588663675e Move backend dictionary and state to MdbHandle 
Attempt to make the backend handling logic thread-safe. This removes the
last MDB_CONSTRUCTOR. Also get rid of some JAVA junk and make the
remaining static variables in backend.c constant. Finally remove some
obsolete fields from MdbFile.

Evan Miller c2087a95cc Merge pull request #30 from nyalldawson/fix_28 
ODBC requires dates formatted in ISO standards
 2020-08-20 06:26:17 -04:00
Evan Miller 5d078838ed [API break] Make date/boolean formats thread safe 
Store the preferred date and boolean formats in the MdbHandle rather
than in global memory.

Evan Miller 2887fa49ed Merge pull request #24 from evanmiller/odbc-thread-safety 
Make the ODBC driver thread-safe. Multiple simultaneous handles should work fine now, but individual handles should only be used by one thread at at time.
 2020-08-19 19:55:29 -04:00
Evan Miller 673c7700b9 Store OLE strings on the statement object 
Also cut MDB_OLE out into its own code path. This removes the last of
the global / thread-local storage in the ODBC driver, I think.
 2020-08-19 19:24:40 -04:00
Evan Miller 55e0d4ff07 Store sqlState separtely on ODBC env / handle / stmts 
Also fix the fact that "08001" was always returned by SQLError instead
of the actual SQL state.

Evan Miller 9020ca9a1e Attempt to make the ODBC driver thread-safe 
I'm not sure if this is a complete solution - some of the global state
has been moved to thread-local storage. So passing an ODBC handle across
threads may have unexpected results. But at least it's not global state.

Each ODBC handle now has its own iconv_t object.

See #23

The new re-entrant parser requires Bison 3, which is not installed

Evan Miller dfd41f2283 Try fixing unixODBC deadlock with -Bsymbolic-functions 
This flag compels the dynamic library to prefer its own function symbols
to those in the global symbol table. This behavior should let us
directly call SQL* functions from inside other SQL* functions without
fear of interference by the host program.
