Subject: [Libpqxx-packagers] Please test libpqxx 4.0 pre-release
Message-ID: <4EC91D10.40004@xs4all.nl>

Hello all,

We're about to release a new version of libpqxx.  As a subscriber to the 
libpqxx-packagers list you are getting advance warning; you'll probably 
want to test the new release on your systems.  If any problems come up 
for your environment, where possible, we'd like to fix them upstream 
before release.

The new version is called 4.0 and is scheduled to appear on
2011-11-27.  Daily snapshots are available at:

   https://pqxx.org/~jtv/tmp/pqxx/

This is a major release, and many important things have changed.  To 
start with, some big API changes:

  * Noticers are gone!  The API relied on std::auto_ptr, which is 
deprecated.  Noticers are replaced by a new class: errorhandler.

  * tablereader and tablewriter are gone.  They weren't safe with 
multibyte encodings.

  * Prepared statements are now weakly-typed, and much simpler.  It was 
mostly support for now-obsolete postgres versions that made them difficult.

  * There were too many nested classes in pqxx::result; fields and 
tuples are now stand-alone classes in the pqxx namespace.

  * In thread-safety metadata, "have_strerror_r" is now 
"have_safe_strerror."  Visual C++ has a strerror_s(), so the name no 
longer fit.

  * For notify/listen, notify_listener has been replaced with 
notification_receiver.  Notifications can have payload strings now.

Many other things have changed: Visual C++ support has improved 
massively.  Support for pre-8.0 versions of postgres has been dropped. 
The C++0x standard is now supported, as are gcc 4.6 and clang++.  Binary 
strings are better, and postgres 9.0-style binary-escaping is supported 
where avaible.  There's a new escaping-and-quoting function for SQL 
identifiers, called quote_name.

Finally, the configure script now supports --enable-documentation and 
--disable-documentation, for faster or more complete builds.

Please post to this list with any problems you may run into that
can affect the upstream source tree or may be relevant to other
package maintainers.  Remember that the list is for people with
other things to do, so please help keep chatter to a minimum.


With thanks,

Jeroen
