  1. Issue 178: Fixed compilation issues with 4.6.2

    authored
    Removed deprecated Row_slice.  The sequence structure changed this from an actual function
    pointer to a void pointer.  GCC 4.6.2 would not allow the assignment of Row_slice to void*.
    This may not build under 2.5.
    
    Also eliminated a bunch of casts to see if newer GCC would uncover other issues.

  1. Python 2 crash when ASCII keyword values passed to connect.

    authored
    MakeConnectionString assumed that values were already converted to Unicode, but this was not
    the case.  Added TextCopyToUnicode to contain the difference which cleans the code up nicely.
    
    Discovered while trying to reproduce Issue 223.

    …xecute.
    
    The saved prepared statement was not cleaned up when a SQLTables or similar function was used.
    If the next execute used the same SQL, pyodbc did not call SQLPrepare.

  1. Issue 145: Update to handle failure.

    authored
    The parameter array is initialized to zero in case of failure during the binding process.
    Therefore it is possible that some values are still zero in FreeInfos.

  1. Issue 188: Segfault when fetching NVARCHAR(MAX) data over 511 bytes

    authored
    The provided fix suggestion looks correct and I can see how it would crash, but was unable to
    reproduce with the unit test.  Probably related to Microsoft vs. FreeTDS differences.

  1. LONGVARCHAR/LONGWVARCHAR fix

    authored
    Was passing the incorrect length when binding, causing SQLPut errors when using long strings
    (usually when inserting long strings) for some drivers.

  1. Issue 186: Added SQLite tests

    authored
    The issue was actually in the ODBC driver, which has been fixed in version
    0.91 of the driver.
    
    There are a couple of issues left, but I'll need to work through them with the driver author:
    reading a zero-byte blob and reading text values in 2 passes.

  1. Added pyodbc.drivers() for Windows builds.

    authored
    In the future, I will try to add the method to other platforms by reading the iODBC and
    unixODBC configuration files.

  1. Issue 121: update with large parameter + no rows updated = error

    authored
    Issue and patch (!) from luke@deller.id.au.  Thanks.
  2. Issue 129: ("select ?", None) fails

    authored
    If SQLDescribeParam cannot tell us the type of a column for a NULL parameter, we'll assume it
    is VARCHAR.  We already do this if SQLDescribeParam is not supported.

  1. Allocated own string for decimals.

    authored
    Was using str(decimal), but it can return items in exponential notation, which I'm not sure
    many databases would handle properly.
  2. More Unicode fixes. Updated mysql tests.

  1. Issue 91: decimal fix; Completely reworked parameters; added leakcheck

    authored
    Fixed issue 91 - handling of decimals was incorrect (off by 1).  Added lots of SQL Server unit
    tests.
    
    To properly fix this, reworked and simplified parameter binding.  Instead of separating the
    memory requirement and the actual memory preparation, it is now performed in 1 step and stored
    in the new ParamInfo structures.
    
    I added a lot of optional malloc calls (not usually used), so I added a PYODBC_LEAK_CHECK
    parameter which causes pyodbc_malloc and pyodbc_free to track allocations.  This is not thread
    safe and is intended only for troubleshooting.
Something went wrong with that request. Please try again.
