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

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.
