6.3.2 to compile (and run) on my Sparc Solaris 2.5.1 box. Details
below:
pgsql.sparc.patch-template: Adds -D__sparc__ and -D__sun__,
defintions which gcc does define, but Sun's cc does not. :(
pgsql.sparc.patch-makefile: Adds a define so that 'lorder'
is not used, as it is not found on my machine.

in a more readable form. -- I am submitting the following patches
to the June 6, 1998 snapshot of PostgreSQL. These patches implement
a port of PostgreSQL to SCO UnixWare 7, and updates the Univel port
(UnixWare 2.x). The patched files, and the reason
for the patch are:
File Reason for the patch ---------------
---------------------------------------------------------------
src/backend/port/dynloader/unixware.c src/backend/port/dynloader/unixware.h
src/include/port/unixware.h src/makefiles/Makefile.unixware
src/template/unixware
Created for the UNIXWARE port.
src/include/port/univel.h
Modifed this file to work with the changes made to
s_lock.[ch].
src/backend/storage/buffer/s_lock.c src/include/storage/s_lock.h
Moved the UNIXWARE (and Univel) tas() function from
s_lock.c to s_lock.h. The UnixWare compiler asm
construct is treated as a macro and needs to be in
the s_lock.h file. I also reworked the tas()
function to correct some errors in the code.
src/include/version.h.in
The use of the ## operator with quoted strings in
the VERSION macro caused problems with the UnixWare
C compiler. I removed the ## operators since they
were not needed in this case. The macro expands
into a sequence of quoted strings that will be
concatenated by any ANSI C compiler.
src/config.guess
This script was modified to recognize SCO UnixWare
7.
src/configure src/configure.in
The configure script was modified to recognize SCO
UnixWare 7.

NS32K machine I contributed. In any case, I now have postgresql-6.3
running again on NetBSD/pc532, a NS32532 machine. The following
changes are needed relative to the src directory. (It looks like
support was partially removed when the files were moved from the
src/backend/storage/.... tree to the src/include tree.)
If you need me to get a current development version of postgresql
for this change let me know. Also, let me know if this code needs
updating due to another code movement that deleted the old NS32K
support.
Thank you.

GCC, the inner "#if defined(__GNUC__)" can just be omitted in that
architecture's block.
The existing arrangement with an outer "#if defined(__GNUC__)"
doesn't have any obvious benefit, and it encourages missed cases
like this one.
BTW, I'd suggest making the definition of clear_lock for HPUX be
static const slock_t clear_lock = {{-1, -1, -1, -1}};
The extra braces are needed to suppress warnings from gcc, and
declaring it const just seems like good practice.
regards, tom lane
but as I don't have access to a sparc for testing I just did what
I could. I am guessing here, but please apply the following to your
pgsql and let me know what happens. Also, cd to src/storage/buffer
and do 'make s_lock_test' as well.

requires manual editing of src/backend/port/getrusage.c, because
its substitute version of getrusage is #if'd out.
There is no good reason for that, because configure won't even
include the file into the Makefile unless the platform hasn't got
getrusage. Furthermore, we only have one working substitute version
of getrusage --- the alleged HPUX syscall-based code doesn't work.
(It causes a coredump because the syscall returns a struct rusage
that's much larger than the stub struct defined in
src/include/rusagestub.h.) The times()-based emulation works fine
on HPUX, however.
I propose, therefore, that getrusage.c should just unconditionally
compile the times-based version, and rely on configure to include
the file only if needed. This will be one less manual configuration
step on all platforms that need this code.
Patch attached.

I see someone missed an ancient bit of shell-scripting lore:
on some older shells, if your script's argument list is empty,
then "$@" generates an empty-string word rather than no word
at all. You need to write ${1+"$@"} to get the latter behavior.
(Read your shell man page to see exactly how that works,
but it does the Right Thing on every Bourne shell.)
In particular, pg_dumpall fails when invoked without any switches
on HPUX 9.*, because pg_dump gets an empty-string argument that it
thinks is the name of the database to dump. I expect this bug
also affects some other OSes, but couldn't tell you just which ones.
Patch attached.
The attached patches respond to discussion that was on pgsql-hackers
around the beginning of June (see thread "libpgtcl bug (and symptomatic
treatment)"). The changes are:
1. Remove code in connectDB that throws away the password after making
a connection. This doesn't really add much security IMHO --- a bad guy
with access to your client's address space can likely extract the
password anyway, to say nothing of what he might do directly. And
there's the serious shortcoming that it prevents PQreset() from working
if the database requires a password.
2. Fix coredump problem: fe_sendauth did not guard against being handed
a NULL password pointer. (This is the proximate cause of the coredump-
during-PQreset problem that Magosanyi Arpad complained of last month.)
3. Remove highly questionable "error recovery" logic in libpgtcl's
pg_exec statement.
I believe the consensus of the discussion last month was in favor of
#1 and #3, but I'm just now getting around to making the change.
I realized that #2 was a bug in process of looking at the change.
Attached are diffs (from current cvs sources) to bring libpq.sgml
and libpq.3 up to date.
It appears that at various times in the past, people have made edits to
one or the other of these files but not both. I propagated some changes
from each into the other, but I don't think I caught every
inconsistency. It'd be real nice if the man pages could be
automatically generated from the SGML...
Making PQrequestCancel safe to call in a signal handler turned out to be
much easier than I feared. So here are the diffs.
Some notes:
* I modified the postmaster's packet "iodone" callback interface to allow
the callback routine to return a continue-or-drop-connection return
code; this was necessary to allow the connection to be closed after
receiving a Cancel, rather than proceeding to launch a new backend...
Being a neatnik, I also made the iodone proc have a typechecked
parameter list.
* I deleted all code I could find that had to do with OOB.
* I made some edits to ensure that all signals mentioned in the code
are referred to symbolically not by numbers ("SIGUSR2" not "2").
I think Bruce may have already done at least some of the same edits;
I hope that merging these patches is not too painful.
