It makes AIX and IRIX not use DST for dates before 1970.
The following expected files need to be removed from the regression tests,
they contain wrong results and are not needed any more.

two transactions create the same table name concurrently, the one that
fails will complain about unique index pg_class_relname_index, rather than
about pg_type_typname_index which'll confuse most people. Free side
benefit: pg_class.reltype is correctly linked to the pg_type entry now.
It's been zero in all but the preloaded pg_class entries since who knows
when.

Man, this brings back some old memories ...

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.

Then I recompiled pgsql and I have compiled a program with ecpg.
I have removed the termios.h, and the ECHO hack.

elog(ERROR) not an Assert trap, since we've downgraded out-of-memory to
elog(ERROR) not a fatal error. Also, change the hard boundary from 256Mb
to 1Gb, just so that anyone who's actually got that much memory to spare
can play with TOAST objects approaching a gigabyte.

allocated by plan nodes are not leaked at end of query. This doesn't
really matter for normal queries, but it sure does for queries invoked
repetitively inside SQL functions. Clean up some other grotty code
associated with tupdescs, and fix a few other memory leaks exposed by
tests with simple SQL functions.

and two 'win32.mak'. Addresses the following:
1) Oops. Spelled fcntl.h wrong in the last one. D'uh.
2) PG_VERSION changed to be defined with " around it. psql/command.c failed
to compile without that.
3) Changed makefiles to use "/MD" and link both psql and libpq.dll against
MSVCRT.DLL instead of a static library. This takes care of the
crash-upon-free in psql.
I *think* this is what is on the "Open 7.1 Items" list as "Magnus Hagander
ODBC Issues?". It has nothing to do with ODBC, but it's the only issue I've
been involved with...

and psql) again. Changes are:
1) psql requires the includes of "io.h" and "fcntl.h" in command.c in order
to make a call to open() work (io.h for _open(), fcntl.h for the O_xxx)
2) PG_VERSION is no longer defined in version.h[.in], but in configure.in.
Since we don't do configure on native win32, we need to put it in
config.h.win32 :-(
3) Added define of SYSCONFDIR to config.h.win32 - libpq won't compile
without it. This functionality is *NOT* tested - it's just defined as "" for
now. May work, may not.
4) DEF_PGPORT renamed to DEF_PGPORT_STR
I have done the "basic tests" on it - it connects to a database, and I can
run queries. Haven't tested any of the fancier functions (yet).
However, I stepped on a much bigger problem when fixing psql to work. It no
longer works when linked against the .DLL version of libpq (which the
Makefile does for it). I have left it linked against this version anyway,
pending the comments I get on this mail :-)
The problem is that there are strings being allocated from libpq.dll using
PQExpBuffers (for example, initPQExpBuffer() on line 92 of input.c). These
are being allocated using the malloc function used by libpq.dll. This
function *may* be different from the malloc function used by psql.exe - only
the resulting pointer must be valid. And with the default linking methods,
it *WILL* be different. Later, psql.exe tries to free() this string, at
which point it crashes because the free() function can't find the allocated
block (it's on the allocated blocks list used by the runtime lib of
libpq.dll).
Shouldn't the right thing to do be to have psql call termPQExpBuffer() on
the data instead? As it is now, gets_fromFile() will just return the pointer
received from the PQExpBuffer.data (this may well be present at several
places - this is the one I was bitten by so far). Isn't that kind of
"accessing the internals of the PQExpBuffer structure" wrong? Instead,
perhaps it shuold make a copy of the string, adn then termPQExpBuffer() it?
In that case, the string will have been allocated from within the same
library as the free() is called.
I can get it to work just fine by doing this - changing from (around line
100 of input.c):
and the same a bit further down in the same function.
But, as I said above, this may be at more places in the code? Perhaps
someone more familiar to it could comment on that?
What do you think shuld be done about this? Personally, I go by the "If you
allocate a piece of memory using an interface, use the same interface to
free it", but the question is how to make it work :-)
Also, AFAIK this only affects psql.exe, so the changes made to the libpq
this patch are required no matter how the other issue is handled.

Magnus

bothering to check the return value --- which meant that in case the
update or delete failed because of a concurrent update, you'd not find
out about it, except by observing later that the transaction produced
the wrong outcome. There are now subroutines simple_heap_update and
simple_heap_delete that should be used anyplace that you're not prepared
to do the full nine yards of coping with concurrent updates. In
practice, that seems to mean absolutely everywhere but the executor,
because *noplace* else was checking.

eliminates a raft of portability issues, including whether sys_nerr
exists, whether the platform has any valid negative errnos, etc. The
downside is minimal: errno shouldn't ever contain an invalid value anyway,
and if it does, reasonably modern versions of strerror will not choke.
This rangecheck idea seemed good at the time, but it's clearly a net loss,
and I apologize to all concerned for having ever put it in.

rewrite of deadlock checking. Lock holder objects are now reachable from
the associated LOCK as well as from the owning PROC. This makes it
practical to find all the processes holding a lock, as well as all those
waiting on the lock. Also, clean up some of the grottier aspects of the
SHMQueue API, and cause the waitProcs list to be stored in the intuitive
direction instead of the nonintuitive one. (Bet you didn't know that
the code followed the 'prev' link to get to the next waiting process,
instead of the 'next' link. It doesn't do that anymore.)

of c.h altogether, and putting it into the only places that use it
(elog.c and exc.c), instead. Modify these routines to check for a
NULL or empty-string return from strerror, too, since some platforms
define strerror to return empty string for unknown errors (what a useless
definition that is ...). Clean up some cruft in ExcPrint while at it.

and remove IsA_Value macro.

whitespace is unimportant in assembly code. Also, move VAX definition
of typedef slock_t to port header files to be like all the other ports.
Note that netbsd.h and openbsd.h are now identical, and I rather think
that freebsd.h is broken in the places where it doesn't agree --- but
I'll leave it to the freebsders to look at that.

least as broken as the one before that :(
Clean up "ISO-style" time interval representation to omit zero fields if
there is at least one non-zero field. Supress some leading plus signs
when not necessary for clarity.
Replace every #ifdef __CYGWIN__ block with a cleaner TIMEZONE_GLOBAL macro

GetRawDatabaseInfo() won't cope with a compressed path spec (much less
a moved-off one). I'm not going to force an initdb for this change,
because it's noncritical --- we're not actually using datpath at all
right now. But it seems a good idea to apply the fix while I'm thinking
about it.

are treated more like 'cancel' interrupts: the signal handler sets a
flag that is examined at well-defined spots, rather than trying to cope
with an interrupt that might happen anywhere. See pghackers discussion
of 1/12/01.

are now critical sections, so as to ensure die() won't interrupt us while
we are munging shared-memory data structures. Avoid insecure intermediate
states in some code that proc_exit will call, like palloc/pfree. Rename
START/END_CRIT_CODE to START/END_CRIT_SECTION, since that seems to be
what people tend to call them anyway, and make them be called with () like
a function call, in hopes of not confusing pg_indent.
I doubt that this is sufficient to make SIGTERM safe anywhere; there's
just too much code that could get invoked during proc_exit().

entry:
----------------------------
revision 1.2
date: 2000/12/04 01:20:38; author: tgl; state: Exp; lines:
+18 -18
Eliminate some of the more blatant platform-dependencies ... it
builds here now, anyway ...
----------------------------
Which basically changes u_int*_t -> uint*_t, so now it does not
compile neither under Debian 2.2 nor under NetBSD 1.5 which
is platform independent<B8> all right. Also it replaces $KAME$
with $Id$ which is Bad Thing. PostgreSQL Id should be added as a
separate line so the file history could be seen.
So here is patch:
* changes uint*_t -> uint*. I guess that was the original
intention
* adds uint64 type to include/c.h because its needed
[somebody should check if I did it right]
* adds back KAME Id, because KAME is the master repository
* removes stupid c++ comments in pgcrypto.c
* removes <sys/types.h> from the code, its not needed

as both a GROUP BY item and an output expression, the top-level Group
node should just copy up the evaluated expression value from its input,
rather than re-evaluating the expression. Aside from any performance
benefit this might offer, this avoids a crash when there is a sub-SELECT
in said expression.
