== PostgreSQL Weekly News - May 25 2008 ==

The May commitfest is finished.  The remaining patches on the queue
are Heikki's map-forks patch, which was WIP not intended to be
committed now; and Merlin and Andrew's libpq hooks patch, which is
still in flux and not ready to commit now.

PgCon 2008 was a smashing success, eh.  People hashed things out at
the developer meeting, complete with a Secret Cabal Meeting.
Participants came in from as far as Pune, India.

== Applied Patches ==

Tom Lane committed:

- Coercion sanity check in ri_HashCompareOp failed to allow for enums,
  as per example from Rod Taylor.  On reflection the correct test here
  is for any polymorphic type, not specifically ANYARRAY as in the
  original coding.

- Make to_char()'s localized month/day names depend on LC_TIME, not
  LC_MESSAGES.  Euler Taveira de Oliveira

- Adjust -Wl,--asneeded test to avoid using the switch if it breaks
  libreadline.  What we will do for compatibility :-(

- Adjust timestamp regression tests to prevent two low-probability
  failure cases.  Recent buildfarm experience shows that it is
  sometimes possible to execute several SQL commands in less time than
  the granularity of Windows' not-very-high-resolution gettimeofday(),
  leading to a failure because the tests expect the value of now() to
  change and it doesn't.  Also, it was recognized some time ago that
  the same area of the tests could fail if local midnight passes
  between the insertion and the checking of the values for
  'yesterday', 'tomorrow', etc.  Clean all this up per ideas from
  myself and Greg Stark.  There remains a window for failure if the
  transaction block is entered exactly at local midnight (so that
  'now' and 'today' have the same value), but that seems
  low-probability enough to live with.  Since the point of this change
  is mostly to eliminate buildfarm noise, back-patch to all versions
  we are still actively testing.

Heikki Linnakangas committed:

- Remove arbitrary 10MB limit on two-phase state file size.  It's not
  that hard to go beoynd 10MB, as demonstrated by Gavin Sharry's
  example of dropping a schema with ~25000 objects.  The really bogus
  thing about the limit was that it was enforced when a state file
  file was read in, not when it was written, so you would end up with
  a prepared transaction that you can't commit or abort, and the only
  recourse was to shut down the server and remove the file by hand.
  Raise the limit to MaxAllocSize, and enforce it also when a state
  file is written.  We could've removed the limit altogether, but
  reading in a file larger than MaxAllocSize would fail anyway because
  we read it into a palloc'd buffer.  Backpatch down to 8.1, where 2PC
  and this issue was introduced.

Bruce Momjian committed:

- Mark TODO as done: "Use LC_TIME for localized weekday/month names."

- In pgsql/src/backend/utils/adt/formatting.c, simplify code now that
  to_(upper|lower|initcap) do not modify the passed string.

Michael Meskes committed:

- Synced parser.  Made ecpg parser use backend provided keyword list.
  Changed whenever test so exit value is 0.

- In pgsql/src/interfaces/ecpg/preproc/Makefile, ecpg_keywords.o also
  depends on preproc.h

- Link in keywords file instead of copying it.  Use #define/#ifdef
  instead of sed to fix include files, this should work on Windows

Magnus Hagander committed:

- Use CRITICAL_SECTION instead of Mutexes for thread-locking in libpq
  on Windows, for better performance.  Per suggestion from Andrew
  Chernow, but not his patch since the underlying code was changed to
  deal with return values.

- In pgsql/src/bin/psql/print.c, fix function headers not matching
  prototype in header file, per compiler warnings on msvc.

- In pgsql/src/tools/msvc/, add include directory required
  after the latest changes to the ecpg build.  Per red Windows
  buildfarm members.
