I haven't had final confirmation from Peter yet, but the attached patch
needs to be applied for the Beta otherwise password and crypt
authentication just won't work.
It puts back the loop in libpq and also fixes a couple of problems with
maintaining compatability with pre-6.3 drivers.
Attached is the patch to fix the warning messages from my code. I also
fixed one which wasn't my code. Apart from the usual warnings about the
bison/yacc generated code I only have one other warning message. This
is in gramm.y around line 2234. I wasn't sure of the fix.
I've also replaced all the calls to free() in gramm.y to calls to
pfree(). Without these I was getting backend crashes with GRANT. This
might already have been fixed.
I've completed the patch to fix the protocol and authentication issues I
was discussing a couple of weeks ago. The particular changes are:
- the protocol has a version number
- network byte order is used throughout
- the pg_hba.conf file is used to specify what method is used to
authenticate a frontend (either password, ident, trust, reject, krb4
or krb5)
- support for multiplexed backends is removed
- appropriate changes to man pages
- the -a switch to many programs to specify an authentication service
no longer has any effect
- the libpq.so version number has changed to 1.1
The new backend still supports the old protocol so old interfaces won't
break.
I have always been under the impression that NULL is not equal to
NULL and that NULL is not equal to anything else either. If this
is the case, then this patch is correct.
If NULL _is_ equal to NULL, then I think there are other problems
in the Group By logic.
lock before older waiters, and having readlock people not share
locks if a writer is waiting for a lock, and waiting writers not
getting priority over waiting readers.
The attached patches will allow postgreSQL to compile successfully on SCO
UNIXWARE 2.1.x. The patches fix the following problems:
1. Configure did not properly recognize the UNIXWARE system as needing the
univel port. It used the sys4 port.
2. Configure did not properly process the CC flag in the template file.
3. There was no working test and set locking implementation for the native
UNIXWARE compiler.
4. The test and set locking used for Intel X86 that was selected by defining
NEED_I386_TAS_ASM could fail in a multi-processor environment.
5. The makefiles for libpq and libpgtcl did not make a shared library for
the univel port.
