The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
This bug is also referenced in
[#61777](https://bugs.php.net/bug.php?id=61777) and is still present in
the latest stable release of the 5.5 branch. I see two tickets exist for
this problem already, and I'm just submitting these changes via github
as a reminder that this is a serious problem for anyone using PDO_ODBC
on the x64 builds.
columns.
We simply add a flag that indicates if we've seen any long columns and will
continue to bind the columns the slow way.
While we're at it, increase the maximum length of the column names that we can
handle.
We need to guess at parameter sizing in some cases (eg: MS Access) as the
SQLDescribeParam() API is an optional feature.
Tidy up error handling.
Add workaround for a shutdown bug that I see with MS ODBC implementation.
(working to determine the precise cause of this).
PDO core test suite now passes all tests.
Note that ODBCRouter doesn't directly implement ODBC 3.0, so
using it here won't really work.
Expand the ODBC 3 check to better explain what happened and
how to make progress (e.g.: use an ODBC manager library like
unixODBC).
The default (which should be safe) is to use the cursor library if it is needed.
If for some reason either the driver or the emulation is broken, you may
override this from your script.
Theoretically better than PHP persistent connections, since ODBC itself takes
care of resetting the connections back to a "ground" state.
Connection pooling defaults to ON, since this is generally useful.
You can turn it off by using:
pdo_odbc.connection_pooling=off
in your php.ini file.
You may configure how ODBC matches connection details to existing connections
by setting this value to "strict" (the default) or "relaxed". You are
encouraged to read the ODBC specs before changing this value.
