1.0 INSTALLATION INSTRUCTIONS

1.1 SUPPORTED ENVIRONMENTS

This service pack is supported on all Intel and Apple Silicon Macs running
macOS Monterey (12.x) and newer.

1.2 PREREQUISITES

The unixODBC driver manager is required for the ODBC driver to function. It
can be installed using the Homebrew package manager, available from: 
      https://brew.sh

Once Homebrew is installed, unixODBC can then be installed with:
      brew install unixodbc

If unixODBC is not installed at the time of installation of this service pack,
the installer will not be able to register the driver with unixODBC, however
the driver can be manually registered once unixODBC has been installed by
running the following command:

      /Library/IBMiAccess/register_driver

To use TLS (SSL), the OpenSSL libraries from Homebrew are required. Either
OpenSSL 1.1 or 3.0 will work, eg.

      brew install openssl@3

1.3 INSTALLING

The service pack includes a standard macOS installer package. It can be
installed by double clicking it or using the pkgutil command from the command
line.

You may get a message when attempting to run the installer that says
"[package] can't be opened because it is from an unidentified developer" and
the dialog box will only have an "OK" button, preventing the package from
being installed. If this occurs, temporarily override the security controls to
allow its installation by right-clicking or ctrl-clicking on the installer and
choose "Open". This will bring up the same dialog with the same warning, but
now there will be "Open" and "Cancel" buttons instead. By choosing "Open", you
can proceed with the installation.

In case the above steps do not work, you can find more information from Apple
at the following web page:
      https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac

2.0 RECOMMENDATIONS/RESTRICTIONS

2.1 IBM i SERVER FIXES

4.0 ENHANCEMENTS AND INTERNAL FIXES

This a list of enhancements and internal fixes.

Version: 1.1.0.29
Build Date = March 2026

• Ensure CCSID conversion parameters used to convert column data in ODBC is
  cleared and not re-used across subsequent SQL statements.

Version: 1.1.0.28
Build Date = May 2024

No enhancements.

Version: 1.1.0.27
Build Date = November 2022

• Add TLS (SSL) support using OpenSSL. This requires that the OpenSSL libraries
  provided by Homebrew are installed, eg openssl@1.1 or openssl@3. OpenSSL
  versions 3.0 and 1.1.1 are supported, with the most recent version found taking
  precedence. Unlike with GSkit on Windows, FIPS mode is not supported.
• Add EnableKeepAlive connection string keyword to enable TCP keepalive support
  as an alternative to using cwbcopwr. Setting to 0 disables keepalives, 1
  enables keepalives, and 2 uses the cwbcopwr value (default).
• Add Timeout connection string keyword to set the socket timeout (in seconds)
  when communicating with the server. This is an alternative to using the
  SQL_ATTR_CONNECTION_TIMEOUT connection attribute or cwbcopwr.
• Add LoginTimeout connection string keyword to set the connection timeout (in
  seconds) when initially connecting and logging in to the server. This is an
  alternative to using the SQL_ATTR_LOGIN_TIMEOUT connection attribute.
• Fix handling of QueryStorageLimit=*NOMAX. Previously, this would get
  interpreted as if 0 had been specified.

Version: 1.1.0.26
Build Date = May 2022

• Unify version number with IBM i Access Client Solutions Windows Application
  Package
• Add support for IBM i 7.5 PWDLVL 4
• Add support for IBM i 7.5 BOOLEAN SQL data type
• Add support for SQL_ATTR_CONNECTION_TIMEOUT and proper support for
  SQL_ATTR_LOGIN_TIMEOUT. In addition, cwbcopwr can be used to set send and
  receive socket timeouts.
• Add cwbcopwr utility
• SQL_DESC_OCTET_LENGTH and SQL_DESC_DISPLAY_LENGTH now take in to account any
  expansion that might occur due to CCSID conversion. For instance, a CHAR(10)
  EBCDIC column will now return 20 instead of 10 for the above attributes when
  the client is in UTF-8 since extended ASCII characters take 2 bytes in UTF-8
  but only 1 byte in EBCDIC. This allows retrieving the full column data in
  PHP's odbc and pdo_odbc extensions, especially on IBM i 7.4 and beyond where
  the default PASE CCSID is 1208.
• Fix bug on big endian systems where error message text would be blank in some
  cases
• Fix getaddrinfo error reporting on macOS and PASE systems. These
  were not being mapped correctly, giving odd error messages, eg.
  "rc=8 - CWB0008 - Insufficient personal computer resources" 
  instead of
  "rc=11001 - CWBCO1004 - Remote address could not be resolved"
• Allow SQL_ATTR_ROW_ARRAY_SIZE to change after data has been (pre-)fetched.
• Remove duplicate DBCLOB() CCSID 13488 row returned by SQLGetTypeInfo when
  called with SQL_ALL_TYPES

Version: 1.1.0.15
Build Date = May 2021

• Implement the current_date, current_time, current_timestamp, timestampadd,
  and timestampdiff ODBC scalar function escape sequences. For more details,
  refer to the following ODBC documents:
  https://docs.microsoft.com/en-us/sql/odbc/reference/develop-app/scalar-function-calls
  https://docs.microsoft.com/en-us/sql/odbc/reference/appendixes/time-date-and-interval-functions
• Add TrimCharFields connection option to trim trailing blank characters when
  retrieving CHAR and GRAPHIC fields. Setting this option to 1 will enable
  trimming, while setting it to 0 (default) will disable trimming.
• Add AlwaysCalculateResultLength connection option. Setting this option to 1
  will prevent the driver from returning SQL_NO_TOTAL, while setting it to 0
  (default) will allow the driver to return SQL_NO_TOTAL. Some applications do
  not expect SQL_NO_TOTAL (-4) and treat it as the actual length, causing
  problems. Note that calculating the actual result length can require repeated
  character conversion, so for performance reasons it's advised to not enable
  this feature unless absolutely necessary.
• Add support for Apple Silicon Macs
• Prevent the driver from breaking after macOS updates by moving conversion
  tables from /Library/Caches/IBMiAccess to /Library/IBMiAccess/conv_tables.

Version: 1.1.0.14
Build Date = Aug 2020

• Better handling of surrogate pairs in UTF-16 when converting to and from
  UTF-8 or UTF-32.
• Send SQL text in UTF-16 instead of UCS-2 when UnicodeSQL is 1 or 2
• Improve ODBC error reporting when server messages contain embedded NUL bytes.
  This should result in fewer "Error message text unavailable" messages.
• Allow setting SQL_ATTR_TXN_ISOLATION to 0 for COMMIT(*NONE). Some driver
  managers restrict the values to those defined by ODBC. In that case, a custom
  driver attribute CWB_ATTR_TXN_ISOLATION (2139) can be used which functions
  identically to SQL_ATTR_TXN_ISOLATION and bypasses the restriction.
• Support for using ODBC escape sequences in connection strings. The primary
  benefit is for passwords which contain any of the special characters '"', '=',
  and ';'. Wrap any value in curly braces "{}" to embed special characters. A
  '}' can be doubled inside an open escape sequence to escape it.
• Fix driver identification on POWER. This should now give ppc, ppc64, and
  ppc64le correctly depending on the platform. Previously it always gave ppc.
• Fix possible crash when fetching an output parameter from a stored procedure
  and tracing is enabled.
• Added cwbmedic script to gather diagnostic material for support personnel.

Version: 1.1.0.13
Build Date = Jul 2020

• Initial release for macOS
• Fix a bug in fetch processing that could cause a call to SQLFetch,
  SQLFetchScroll, or SQLExtendedFetch after a forward-only cursor had reached
  the end of data in a previous fetch call to return the last rowset of data
  again instead of returning SQL_NO_DATA. In some cases, this could result in
  another fetch call being made to the server, resulting in an error.
