  Own Id: OTP-14475 Aux Id: ERL-409, PR-1493

## ODBC 2.12

### Improvements and New Features

- Change configure to skip odbc for old MACs, the change in PR-1227 is not backwards compatible with old MACs, and we do not see a need to continue support for such old versions. However it is still possible to make it work on such machines using the --with-odbc configure option.

  * POTENTIAL INCOMPATIBILITY *

  Own Id: OTP-14083

## ODBC 2.11.3

### Fixed Bugs and Malfunctions

- ODBC build configure has been updated to accept Mac OS X El Capitan. Fixed by Lee Bannard.

  Own Id: OTP-13781

## ODBC 2.11.2

### Improvements and New Features

- Configure enhancement for better handling program paths used in the build process

  Own Id: OTP-13559

## ODBC 2.11.1

### Improvements and New Features

- 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.

  Own Id: OTP-12935

## ODBC 2.11

### Improvements and New Features

- Change license text from Erlang Public License to Apache Public License v2

  Own Id: OTP-12845

## ODBC 2.10.22

### Fixed Bugs and Malfunctions

- 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.

  Own Id: OTP-12260

### Improvements and New Features

- The commands longer than 127 chars sent to odbc server crashed it, e.g. a connection string with driver path and some additional parameters.

  Own Id: OTP-12346

- Distribute `autoconf` helpers to applications at build time instead of having multiple identical copies committed in the repository.

  Own Id: OTP-12348

## ODBC 2.10.21

### Fixed Bugs and Malfunctions

- Fix compiler warnings reported by LLVM

  Own Id: OTP-12138

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

  Own Id: OTP-12153

## ODBC 2.10.20

### Fixed Bugs and Malfunctions

- Application upgrade (appup) files are corrected for the following applications:

  `asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl`

  A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

  (Thanks to Tobias Schlager)

  Own Id: OTP-11744

### Improvements and New Features

- Removed warnings at compile time by adding missing include file (Thanks to Anthony Ramine)

  Own Id: OTP-11569

- 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.

  Own Id: OTP-11630

## ODBC 2.10.19

### Fixed Bugs and Malfunctions

- Updated configure test for header files sql.h and sqlext.h to function correctly on windows.

  Own Id: OTP-11574

## ODBC 2.10.18

### Improvements and New Features

- Configure now also checks for the existence of the sql.h header file

  Own Id: OTP-11483

## ODBC 2.10.17

### Fixed Bugs and Malfunctions

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

  Own Id: OTP-11193

### Improvements and New Features

- Introduced functionality for inspection of system and build configuration.

  Own Id: OTP-11196

- Prevent odbcserver crash if it's executed and supplied incorrect data to stdin. Thanks to Sergei Golovan.

  Own Id: OTP-11233

## ODBC 2.10.16

### Improvements and New Features

- Fix a 64bit related bug in odbcserver. Thanks to Satoshi Kinoshita.

  Own Id: OTP-10993

- Postscript files no longer needed for the generation of PDF files have been removed.

  Own Id: OTP-11016

- Fix checking for odbc in standard locations when "with-odbc" flag present. Thanks to Alexey Saltanov.

  Own Id: OTP-11126

## ODBC 2.10.15

### Improvements and New Features

- Fixed calling odbc:param_query/3 and odbc:param_query/4 with unparameterized query string and empty parameters list. Thanks to Danil Onishchenko.

  Own Id: OTP-10798

## ODBC 2.10.14

### Improvements and New Features

- Under Unix enable TCP_NODELAY to disable Nagel's socket algorithm. Thanks to Andy Richards

  Impact: Performance gain on Unix systems

  Own Id: OTP-10506

- 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.

  Own Id: OTP-10603

- 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.

  Own Id: OTP-10630

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

  Own Id: OTP-10665

- Fix aotocommit for Oracle ODBC driver in Linux. Thanks to Danil Onishchenko.

  Own Id: OTP-10735

## ODBC 2.10.13

### Fixed Bugs and Malfunctions

- 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

  Own Id: OTP-10206

## ODBC 2.10.12

### Fixed Bugs and Malfunctions

- 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)

  Own Id: OTP-9716

### Improvements and New Features

- Erlang/OTP can now be built using parallel make if you limit the number of jobs, for instance using '`make -j6`' or '`make -j10`'. '`make -j`' does not work at the moment because of some missing dependencies.

  Own Id: OTP-9451

## ODBC 2.10.11

### Fixed Bugs and Malfunctions

- When using output parameters the internal odbc state was not correctly cleaned causing the next call to param_query to misbehave.

  Own Id: OTP-9444

- XML files have been corrected.

  Own Id: OTP-9550 Aux Id: OTP-9541

### Improvements and New Features

- Add code to handle old ODBC drivers on solaris. Also adds tests with MySQL.

  Own Id: OTP-8407

- Odbc now supports SQL_WLONGVARCHAR, thanks to Hanfei Shen for the patch.

  Own Id: OTP-8493

## ODBC 2.10.10

### Fixed Bugs and Malfunctions

- Better error messages for connection issues.

  Own Id: OTP-9111

## ODBC 2.10.9

### Improvements and New Features

- 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 2.10.8

### Improvements and New Features

- 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.

  * POTENTIAL INCOMPATIBILITY *

  Own Id: OTP-8511

## ODBC 2.10.7

### Fixed Bugs and Malfunctions

- The odbc application can now be compiled on FreeBSD. (Thanks to Kenji Rikitake.)

  Own Id: OTP-8444

### Improvements and New Features

- Cross compilation improvements and other build system improvements.

  Most notable:

  - Lots of cross compilation improvements. The old cross compilation support was more or less non-existing as well as broken. Please, note that the cross compilation support should still be considered as experimental. Also note that old cross compilation configurations cannot be used without modifications. For more information on cross compiling Erlang/OTP see the `$ERL_TOP/INSTALL-CROSS.md` file.
  - Support for staged install using DESTDIR. The old broken `INSTALL_PREFIX` has also been fixed. For more information see the `$ERL_TOP/INSTALL.md` file.
  - Documentation of the `release` target of the top `Makefile`. For more information see the `$ERL_TOP/INSTALL.md` file.
  - `make install` now by default creates relative symbolic links instead of absolute ones. For more information see the `$ERL_TOP/INSTALL.md` file.
  - `$ERL_TOP/configure --help=recursive` now works and prints help for all applications with `configure` scripts.
  - Doing `make install`, or `make release` directly after `make all` no longer triggers miscellaneous rebuilds.
  - Existing bootstrap system is now used when doing `make install`, or `make release` without a preceding `make all`.
  - The `crypto` and `ssl` applications use the same runtime library path when dynamically linking against `libssl.so` and `libcrypto.so`. The runtime library search path has also been extended.
  - The `configure` scripts of `erl_interface` and `odbc` now search for thread libraries and thread library quirks the same way as ERTS do.
  - The `configure` script of the `odbc` application now also looks for odbc libraries in `lib64` and `lib/64` directories when building on a 64-bit system.
  - The `config.h.in` file in the `erl_interface` application is now automatically generated in instead of statically updated which reduces the risk of `configure` tests without any effect.

  (Thanks to Henrik Riomar for suggestions and testing)

  (Thanks to Winston Smith for the AVR32-Linux cross configuration and testing)

  * POTENTIAL INCOMPATIBILITY *

  Own Id: OTP-8323

- 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.

  Own Id: OTP-8343

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

  Own Id: OTP-8347

### Known Bugs and Problems

- 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.

  Own Id: OTP-8407

## ODBC 2.10.6

### Fixed Bugs and Malfunctions

- Applied a patch from Andrew Thompson, which fixes some error cases.

  Own Id: OTP-8291

### Improvements and New Features

- The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

  Own Id: OTP-8250

## ODBC 2.10.5

### Fixed Bugs and Malfunctions

- A missing return statement in a non void function has been fixed in `odbc`. (Thanks to Nico Kruber)

  Own Id: OTP-7978

## ODBC 2.10.4

### Improvements and New Features

- param_query now handles the in_or_out parameter correctly.

  Own Id: OTP-7720

- Changed the internal socket use so that it will become more robust to non-functional ipv6 and fallback on ipv4.

  Own Id: OTP-7721

## ODBC 2.10.3

### Improvements and New Features

- Configure update for mac.

  Own Id: OTP-7418

### Known Bugs and Problems

- describe_table/[2,3] on mac gives an empty result

  Own Id: OTP-7478

## ODBC 2.10.2

### Fixed Bugs and Malfunctions

- 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.

  Own Id: OTP-7297

## ODBC 2.10.1

### Improvements and New Features

- Now supports out and input parameters for stored procedures.

  Own Id: OTP-7019

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

  Own Id: OTP-7294

- 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.

  Own Id: OTP-7307

### Known Bugs and Problems

- 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

## ODBC 2.10

### Improvements and New Features

- 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

## ODBC 2.0.9

### Improvements and New Features

- 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.

  * POTENTIAL INCOMPATIBILITY *

  Own Id: OTP-6984

- 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.

  Own Id: OTP-6987

## ODBC 2.0.8

### Improvements and New Features

- Minor Makefile changes.

  Own Id: OTP-6689

## ODBC 2.0.7

### Fixed Bugs and Malfunctions

- 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.

  Own Id: OTP-5504

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

  Own Id: OTP-6363

## ODBC 2.0.6

### Fixed Bugs and Malfunctions

- pthread header and library mismatch on linux systems (at least some SuSE and Debian) with both NPTL and Linuxthreads libraries installed.

  Own Id: OTP-5981

### Improvements and New Features

- Changed configure to find odbc in /usr/local too

  Own Id: OTP-5966

### Known Bugs and Problems

- When using a parameterized query on a windows platform the data is inserted in the table on the sql-server but for some reason the connection is lost.

  Own Id: OTP-5504

## ODBC 2.0.5

### Fixed Bugs and Malfunctions

- Fixed bug, reported error when deleting nonexisting rows, thanks to Laura M. Castro for reporting this.

  Own Id: OTP-5759

### Known Bugs and Problems

- When using a parameterized query on a windows platform the data is inserted in the table on the sql-server but for some reason the connection is lost.

  Own Id: OTP-5504

## Odbc 2.0.4

### Improvements and New Features

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

  Own Id: OTP-5501

- 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.

  Own Id: OTP-5502

### Known Bugs and Problems

- When using a parameterized query on a windows platform the data is inserted in the table on the sql-server but for some reason the connection is lost.

  Own Id: OTP-5504

## Odbc 2.0.3

### Improvements and New Features

- 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

## odbc 2.0.2

### Fixed Bugs and Malfunctions

- When issuing a batch of queries and one of the queries fail the odbc port program crashed. This is no longer the case.

  Own Id: OTP-5176

## odbc 2.0.1

### Improvements and New Features

- 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.

  Own Id: OTP-5100

## odbc 2.0

### Improvements and New Features

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

  Own Id: OTP-4642 Aux Id: seq7766

- The old interface that became deprecated in odbc 1.0 has now been removed.

  * POTENTIAL INCOMPATIBILITY *

  Own Id: OTP-4794

- 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.

  Own Id: OTP-4813

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

  Own Id: OTP-4821

- 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.

  * POTENTIAL INCOMPATIBILITY *

  Own Id: OTP-4850

- 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.
