Evan Miller cea7553e00 Export fakeglib symbols from main library 2020-08-31 13:27:08 -04:00
Evan Miller be888e0dd7 Support fuzz testing (#4) 
Quickstart (requires Clang 6 or later):

$ export LIB_FUZZING_ENGINE=/path/to/fuzzing/library.a
$ ./configure --enable-fuzz-testing
$ make
$ cd src/fuzz
$ make fuzz_mdb
$ ./fuzz_mdb

Also add a new `mdb_open_buffer function` to facilitate in-memory
fuzz-testing. This requires fmemopen, which may not be present on all
systems. The internal API has been reworked to use file streams instead
of file descriptors. This allows reading from memory and reading from
files using a consistent API.

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

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.

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.

Evan Miller 55e0d4ff07 Store sqlState separtely on ODBC env / handle / stmts

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
