e9f4c6c786 Remove GLib dependency WIP 
Add a shim implementing half-assed versions of most of the GLib
functions used by MDB Tools. If GLib is detected at compile-time,
use it, otherwise use the shim.

This work is not complete, as the option-parsing code is not yet
implemented - so most of the command-line tools crash.

e22791606f odbc: support reading OLE entries 
This adds support for reading OLE objects to the ODBC driver. The APIs
for reading OLE appear somewhat idiosyncratic, so we read the string
fully and stash it in a static variable.

Tested by reading an old Access database, with checking for memory leaks.

1b8c2ca483 odbc: don't assume sizeof(int) == sizeof(long) 
Most  64-bit environments use 64 bit longs and 32 bit ints; as such,
comparing an int to LONG_MIN/MAX makes no sense. Since SQL LONGs
appear limited to 32 bits, I assume INT_MIN/MAX was intended.

e2449c11f3 Added strptime function to SQL parser as a feature. This is needed to i.e. be able to query time-fields in DB and to use dates <1.1.1970 and >19.1.2038. All changes should be backwards-compatible to not break existing queries. 2015-08-30 11:23:57 +02:00

d0472d96ba Added proper SQL engine termination 
Since the SQL engine is initialized in _SQLAllocEnv, the engine should be also terminated in SQLFreeEnv.

bcc7ad5a7a Fixed memory leak in _SQLFreeEnv 
Memory allocated for the _henv structure was not being freed which caused a small memory leak.

5888c4a52c Correction to SQLGetData string length handling 
According to http://download.oracle.com/otn_hosted_doc/timesten/703/TimesTen-Documentation/ms.odbc.pdf and https://msdn.microsoft.com/en-us/library/ms710980(v=vs.85).aspx, the string length should not include the NULL character at the end.

Previous behavior would likely work without problems for any language that uses C-style null terminated strings, but adds a null character in the string when using the driver with a language that does not use C-style strings.

Ran autoupdate

Replaced AC_TRY_LINK/AC_TRY_COMPILE by AC_LINK_IFELSE/AC_COMPILE_IFELSE

Droped -I$(top_srcdir)/include from CFLAGS since AC_CONFIG_HEADERS already
adds the -I

Fixed bison detection

Added AM_PROG_AR as required by autoreconf -i -Wall

Updated NEWS and .gitignore

eefddaffcc Don't distribute mdbprivate.h and mdbodbc.h 
mdbprivate is.... private.

mdbodbc.h has no reason to be public: People who want to use the plugin
should use the public odbc.h headers. And having this private will permit
hdbc cleanup.

40d1ecd11f Update _SQLGetData - Was incorrectly attempting to validate input of an output only parameter 
According to the spec, pcbValue is designated as an output only variable, so there is no need to validate any incoming values.

Some packages do not initialize this variable before passing it into the function call; this will randomly result in an improperly thrown error.

Removed the input validation.

And map file did not really support versions but only list which symbol
to export. So this is more simple.
