This document describes the changes made to the odbc application.
New application variable to set timeout of internal communication setup between the erlang code and the c-port program that interfaces the odbc driver. This can be useful if you have an underlying system that is slow due to heavy load at startup.
With this environment variable you can easily bypass and tailor odbc to the needs of the underlying actual system without changing the configuration. Which is a good thing because this value is very system specific.

OS X Mavericks is based on Darwin version 13.x, and Yosemite on 14.x. Change the ODBC configure.in script to recognize these versions.

Implement --enable-sanitizers[=sanitizers]. Similar to debugging with Valgrind, it's very useful to enable -fsanitize= switches to catch bugs at runtime.

Application upgrade (appup) files are corrected for the following applications:
A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

Apple has removed iODBC in OS X 10.9 Mavericks, but forgot to remove all binaries, adopt configure so that will be possible to build odbc with own installation.

Updated configure test for header files sql.h and sqlext.h to function correctly on windows.
Own Id: OTP-11574
Configure now also checks for the existence of the sql.h header file

The format of the xml source for documentation is corrected in order to conform to the DTDs and to pass xmllint without errors.

Under Unix enable TCP_NODELAY to disable Nagel's socket algorithm. Thanks to Andy Richards
Impact: Performance gain on Unix systems

Added extended_errors option to ODBC
When enabled, this option alters the return code of ODBC operations that produce errors to include the ODBC error code as well as the native error code, in addition to the ODBC reason field which is returned by default. Thanks to Bernard Duggan.

Where necessary a comment stating encoding has been added to Erlang files. The comment is meant to be removed in Erlang/OTP R17B when UTF-8 becomes the default encoding.

Some examples overflowing the width of PDF pages have been corrected.

Add support for NULL value in odbc:param_query
Support atom 'null' in odbc:param_query as database NULL value Fix "ODBC: received unexpected info:{tcp_closed, ...}" when connection is terminated. Fix possible access violation with 64bit ODBC. Thanks to Maxim Zrazhevskiy

An ODBC process should exit normally if its client exits with 'shutdown'
There is nothing strange about the client shutting down, so the ODBC process should exit normally to avoid generating a crash report for a non-problem. (Thanks to Magnus Henoch)

Odbc now supports SQL_WLONGVARCHAR, thanks to Hanfei Shen for the patch.
Own Id: OTP-8493
Better error messages for connection issues.
Own Id: OTP-9111
Ipv6 is now supported on Windows as well as on UNIX for internal socket communication. (ODBC uses sockets instead of the "Erlang port pipes" as some ODBC-drivers are known to mess with stdin/stdout.)
Loopback address constants are used when connecting the c-side to the erlang-side over local socket API avoiding getaddrinfo problems, and the {ip, loopback} option is added as a listen option on the erlang-side. Also cleaned up the TIME_STAMP contribution.
Own Id: OTP-8917
ODBC now handles the types SQL_WCHAR and SQL_WVARCHAR. Thanks to Juhani Ränkimies. ODBC also has a new connection option to return all strings as binaries and also expect strings to be binaries in the param_query function. These changes provides some unicode support.
Own Id: OTP-7452
Now supports SQL_TYPE_TIMESTAMP on the format {{YY, MM, DD}, {HH, MM, SS}}. Thanks to Juhani Ränkimies.

The documentation is now possible to build in an open source environment after a number of bugs are fixed and some features are added in the documentation build process.
- The arity calculation is updated.
- The module prefix used in the function names for bif's are removed in the generated links so the links will look like "http://www.erlang.org/doc/man/erlang.html#append_element-2" instead of "http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".
- Enhanced the menu positioning in the html documentation when a new page is loaded.
- A number of corrections in the generation of man pages (thanks to Sergei Golovan)
- The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.

odbc:param_query() now properly indicates if nothing was updated. (Thanks to Paul Oliver.)

The ODBC test cases are failing for linux and MacOSX There is problems with setting of options on odbc-connections, and the odbcserver just exits with an exit code.

SQLINTEGERs where not retrieved correctly on 64 bit platforms as an SQLINTEGER is defined to be a 32 bit integer and not a true long.

ODBC is now prebuilt for SLES10 in the commercial build and parameters to error_logger:error_report/1 has been corrected.

Parametrized queries will now work correctly when using Erlang R12B-2 on Linux (SuSE 10.3), MySQL 5.0.45, myodbc 3.51 and unixODBC 2.2.12. Earlier it could happen that an error was returned even though data was correctly inserted into the database.

SQLINTEGERs are not retrieved correctly on 64 bit platforms as an SQLINTEGER seems to be defined to be a 32 bit integer and not a true long.
Own Id: OTP-7297
Enhanced configure to among other things work better when there is a library found but it is not usable e.i. 32 bit library in 64 bit build.
Own Id: OTP-7062
The odbc application now has to be explicitly started and stopped e.i. it will not automatically be started as a temporary application as it did before. Although a practical feature when testing things in the shell, it is not desirable that people take advantage of this and not start the odbc application in a correct way in their products. Added functions to the odbc API that calls application:start/stop.

Changed Makefile.in so that odbc is not disabled on 64-bits architectures. It was earlier disabled due to that it had never been tested in that environment.

Minor Makefile changes.

When using a parameterized query on a windows platform the data was inserted in the table on the sql-server but the connection was lost, this seems to be due to a compiler error that has now been worked around, but further investigation is ongoing to verify that that really was the problem.

param_query/[3,4] could return an unexpected row count for some drivers, in this case a postgresdriver.

/usr was added as a default place for configure to look for the odbc library on unix/linux platforms.

A legacy timer in the c port program was set to infinity. All timeout handling is handled by the erlang code and a extra timeout in the c code will just lead to confusion if it is released.

odbc now uses configure as all "normal" applications instead of providing special Makefiles for each commercial supported platform. This also makes it easier to build odbc on non supported platforms.
Own Id: OTP-5437
When issuing a batch of queries and one of the queries fail the odbc port program crashed. This is no longer the case.

Added use of the socket option TCP_NODELAY, as in the case of Erlang odbc the Nagel algorithm will never help, but always cause an unnecessary delay.

Erlang ODBC now handles batches of queries and can return multiple result sets.

The old interface that became deprecated in odbc 1.0 has now been removed.
*** POTENTIAL INCOMPATIBILITY ***

The port program now sends different exit codes to Erlang when it exits due to failure. This instead of sending the same exit code and then trying to write to stderr. Erlang encodes the exit code to a descriptive atom.

Erlang ODBC now supports parameterized queries for the most common ODBC data types.

SQL_NUMERIC and SQL_DECIMAL columns are converted to integer and float values if possible.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-4826
Result sets are now by default returned as a list of tuples which is the most intuitive and useful mapping. To keep some degree of backwards compatibility you may turn this off to get the old behavior that result sets are returned as lists of lists. However do not use this in new code as it is considered a deprecated feature that eventually will disappear.

The odbc implementation now mostly uses sockets to communicate between the c and the erlang process, this is to avoid a lot of problems arising from different odbc-drivers doing strange things that disturbed the port-program communication mechanism.
