Windows. The test itself is bypassed in configure as discussed, and
libpq has been updated appropriately to allow it to build in thread-safe
mode.

patch adds missing checks to the call sites of malloc(), strdup(),
PQmakeEmptyPGresult(), pqResultAlloc(), and pqResultStrdup(), and updates
the documentation. Per original report from Volkan Yazici about
PQmakeEmptyPGresult() not checking for malloc() failure.

macros around strings that were missing them.

Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...

handling in SIGPIPE processing; avoid unnecessary pollution of application
link-symbol namespace; spell 'pointer to function' in the conventional
way.

calling applications. This is done by blocking sigpipe in the libpq
thread and using sigpending/sigwait to possibily discard any sigpipe we
generated.

malloc() doesn't set errno, so most uses were buggy anyway.

global variables are problematic on this platform. Simplest solution
seems to be to initialize pthread key variable to 0. Also, rename this
variable and check_sigpipe_handler to something involving "pq" to
avoid gratuitous pollution of application namespace.

* removed a few redundant defines
* get_user_name safe under win32
* rationalized pipe read EOF for win32 (UPDATED PATCH USED)
* changed all backend instances of sleep() to pg_usleep
- except for the SLEEP_ON_ASSERT in assert.c, as it would exceed a
32-bit long [Note to patcher: If a SLEEP_ON_ASSERT of 2000 seconds is
acceptable, please replace with pg_usleep(2000000000L)]
I added a comment to that part of the code:
/*
* It would be nice to use pg_usleep() here, but only does 2000 sec
* or 33 minutes, which seems too short.
*/
sleep(1000000);

ignore SIGPIPE from send() in libpq, but terminate on any other SIGPIPE,
unless the user installs their own signal handler.
This is a minor fix because the only time you get SIGPIPE from libpq's
send() is when the backend dies.

client
utilities (libpq.dll and psql.exe) for win32 (missing defines,
adjustments to
includes, pedantic casting, non-existent functions) per:
http://developer.postgresql.org/docs/postgres/install-win32.html.
It compiles cleanly under Windows 2000 using Visual Studio .net. Also
compiles clean and passes all regression tests (regular and contrib)
under Linux.
In addition to a review by the usual suspects, it would be very
desirable for someone well versed in the peculiarities of win32 to take
a look.

are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.

Fixed libpq printing functions
|
|
it seems more suitable for the naming convention in libpq.
New function PQsetClientEncoding added. It makes possible to change
the client encoding on the fly without setting PGCLIENTENCODING.

Initdb help correction
Changed end/abort to commit/rollback and changed related notices
Commented out way old printing functions in libpq
Fixed a typo in alter table / alter column

Here is a patch to bring both libpq and psql to a state where it compiles on
win32 (native) again. A lot of things have changed, and I have not been able
to keep up with them all, so it has been broken for quite a while.
After this patch, at least it compiles. It also talks "basic talk" to the
server, but I have not yet tested all things. Sending queries, and using
e.g. \d or \dt works fine. The rest will have to be tested further.
It also bumps the version on libpq.dll to 7.0.
Everything should be enclosed in #ifdef WIN32, unless I have missed
something. Except for one or maybe two places where I have moved a #include
that should not be used on win32 from the "global area" into a "#ifndef
WIN32 area".

* Add use of 'const' for varibles in source tree
(which is misspelled, btw.)
I went through the front-end libpq code and did so. This affects in
particular the various accessor functions (such as PQdb() and
PQgetvalue()) as well as, by necessity, the internal helpers they use.
I have been really thorough in that regard, perhaps some people will find
it annoying that things like
char * foo = PQgetvalue(res, 0, 0)
will generate a warning. On the other hand it _should_ generate one. This
is no real compatibility break, although a few clients will have to be
fixed to suppress warnings. (Which again would be in the spirit of the
above TODO.)
In addition I replaced some int's by size_t's and removed some warnings
(and generated some new ones -- grmpf!). Also I rewrote PQoidStatus (so it
actually honors the const!) and supplied a new function PQoidValue that
returns a proper Oid type. This is only front-end stuff, none of the
communicaton stuff was touched.
The psql patch also adds some new consts to honor the new libpq situation,
as well as fixes a fatal condition that resulted when using the -V
(--version) option and there is no database listening.
So, to summarize, the psql you should definitely put in (with or without
the libpq). If you think I went too far with the const-mania in libpq, let
me know and I'll make adjustments. If you approve it, I will also update
the docs.

error/notice message lengths, and number of fields per tuple. Add
pqexpbuffer.c/.h, a frontend version of backend's stringinfo module.
This is first step in applying Mike Ansley's long-query patches,
even though he didn't do any of these particular changes...

been applied. The patches are in the .tar.gz attachment at the end:
varchar-array.patch this patch adds support for arrays of bpchar() and
varchar(), which where always missing from postgres.
These datatypes can be used to replace the _char4,
_char8, etc., which were dropped some time ago.
block-size.patch this patch fixes many errors in the parser and other
program which happen with very large query statements
(> 8K) when using a page size larger than 8192.
This patch is needed if you want to submit queries
larger than 8K. Postgres supports tuples up to 32K
but you can't insert them because you can't submit
queries larger than 8K. My patch fixes this problem.
The patch also replaces all the occurrences of `8192'
and `1<<13' in the sources with the proper constants
defined in include files. You should now never find
8192 hardwired in C code, just to make code clearer.
