9b4bfbdc2c Handle reading of startup packet and authentication exchange after forking
a new postmaster child process.  This should eliminate problems with
authentication blocking (e.g., ident, SSL init) and also reduce problems
with the accept queue filling up under heavy load.

The option to send elog output to a different file per backend (postgres -o)
has been disabled for now because the initialization would have to happen
in a different order and it's not clear we want to keep this anyway.

e542036461 Native Language Support (NLS)
Use --enable-nls to turn it on; see installation instructions for details.
See developer's guide how to make use of it in programs and how to add
translations.

psql sources have been almost fully prepared and an incomplete German
translation has been provided.  In the backend, only elog() calls are
currently translatable, and the provided German translation file is more
of a placeholder.

under the postmaster --- specifically, if we are a standalone backend
running under the initdb script, this is critical!

e9c936ff38 Remove rangechecks on errno; just call strerror unconditionally. This
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.

023a48b811 Deal with C++ incompatibility of sys_nerr declaration by taking it out
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.

36839c1927 Restructure backend SIGINT/SIGTERM handling so that 'die' interrupts
are treated more like 'cancel' interrupts: the signal handler sets a

with an interrupt that might happen anywhere.  See pghackers discussion
of 1/12/01.

08ede423d1 Make elog() switch to ErrorContext while invoking libpq output routines,

d63a762f79 Ok, You guys are probably tired of me, BUT, here is another one, that
adds the facility to set the program name used in syslog.
(this includes the other ones).

One gotcha, the parser doesn't like special characters in strings.
For example, i tried to use pg-test, and if failed the parse coming
from the postgresql.conf file.

I don't think it's a showstopper..

7ea8403c8a The beos port in the source tree doesn't even compile. and even
after that dynamic loading isn't working and shared memory handling is
broken.

        Attached with this message, there is a Zip file which contain :

        * beos.diff = patch file generated with difforig
        * beos = folder with beos support files which need to be moved in /
src/backend/port
        * expected = foler with three file for message and precision
difference in regression test
        * regression.diff = rule problem (need to kill the backend manualy)
        * dynloader = dynloader files (they are also in the pacth files,
but there is so much modification that I have join full files)

        Everything works except a problem in 'rules' Is there some problems
with rules in the current tree ? It used to works with last week tree.

87c0e623ba New diff that now covers the entire tree. Applying this gets postgresql
working on the VERY latest version of BeOS.  I'm sure there will be
alot of comments, but then if there weren't I'd be disappointed!

Thanks for your continuing efforts to get this into your tree.

Haven't bothered with the new files as they haven't changed.

BTW Peter, the compiler is "broken" about the bool define and so on.
I'm filing a bug report to try and get it addressed.  Hopefully then we
can tidy up the code a bit.

I await the replies with interest :)

1aebc3618a First phase of memory management rewrite (see backend/utils/mmgr/README
for details).  It doesn't really do that much yet, since there are no
short-term memory contexts in the executor, but the infrastructure is
in place and long-term contexts are handled reasonably.  A few long-
standing bugs have been fixed, such as 'VACUUM; anything' in a single
query string crashing.  Also, out-of-memory is now considered a
recoverable ERROR, not FATAL.
Eliminate a large amount of crufty, now-dead code in and around
memory management.
Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and
backend startup.

That means you can now set your options in either or all of $PGDATA/configuration,
some postmaster option (--enable-fsync=off), or set a SET command. The list of
options is in backend/utils/misc/guc.c, documentation will be written post haste.

pg_options is gone, so is that pq_geqo config file. Also removed were backend -K,
-Q, and -T options (no longer applicable, although -d0 does the same as -Q).

Added to configure an --enable-syslog option.

a2226ad237 contrib-array.patch
this is an old patch which I have already submitted and never seen
        in the sources. It corrects the datatype oids used in some iterator
        functions. This bug has been reported to me by many other people.

contrib-datetime.patch

        some code contributed by Reiner Dassing <dassing@wettzell.ifag.de>

contrib-makefiles.patch

        fixes all my contrib makefiles which don't work with some compilers,
        as reported to me by another user.

contrib-miscutil.patch

        an old patch for one of my old contribs.

contrib-string.patch

        a small change to the c-like text output functions. Now the '{'
        is escaped only at the beginning of the string to distinguish it
        from arrays, and the '}' is no more escaped.

elog-lineno.patch

        adds the current lineno of CopyFrom to elog messages. This is very
        useful when you load a 1 million tuples table from an external file
        and there is a bad value somehere. Currently you get an error message
        but you can't know where is the bad data. The patch uses a variable
        which was declared static in copy.c. The variable is now exported
        and initialized to 0. It is always cleared at the end of the copy
        or at the first elog message or when the copy is canceled.
        I know this is very ugly but I can't find any better way of knowing
        where the copy fails and I have this problem quite often.

plperl-makefile.patch

        fixes a typo in a makefile, but the error must be elsewhere because
        it is a file generated automatically. Please have a look.

tprintf-timestamp.patch

        restores the original 2-digit year format, assuming that the two
        century digits don't carry much information and that '000202' is
        easier to read than 20000202. Being only a log file it shouldn't
        break anything.

Please apply the patches before the next scheduled code freeze.

I also noticed that some of the contribs don't compile correcly. Should we
ask people to fix their code or rename their makefiles so that they are
ignored by the top makefile?

8a40400d40 elog() was set up to call abort() if it saw an ERROR or FATAL exit
during InitProcessingMode and the CurrentTransactionState was neither
TRANS_DEFAULT nor TRANS_DISABLED.  Unfortunately, after someone's recent
change to start the transaction manager earlier in startup than it used
to be started, that caused an abort() and consequent database system
reset on quite harmless errors (such as rejecting an invalid user name!).
As far as I can see, the test on CurrentTransactionState was completely
useless anyway, so I've removed it.

316c4c57e2 Clean up some problems in error recovery --- elog() was pretty broken
for the case of errors in backend startup, and proc_exit's method for
coping with errors during proc_exit was *completely* busted.  Fixed per

e1492cc34c Modify elog() logic so that it won't try to longjmp(Warn_restart) before
Warn_restart has been set by the backend main loop.  This means that
elog(ERROR) or elog(FATAL) in the postmaster or during backend startup
now have well-defined behavior: proc_exit() rather than coredump.
In the case of elog() inside the postmaster, I think that proc_exit()
is probably not enough --- don't we want our child backends to be
forced to quit too?  But I don't understand Vadim's recent changes in
this area, so I'll leave it to him to look over and tweak if needed.

51f62d505e Standardize on MAXPGPATH as the size of a file pathname buffer,
eliminating some wildly inconsistent coding in various parts of the
system.  I set MAXPGPATH = 1024 in config.h.in.  If anyone is really
convinced that there ought to be a configure-time test to set the
value, go right ahead ... but I think it's a waste of time.

b399805e22 Eliminate elog()'s hardwired limit on length of an error message.
This change seems necessary in conjunction with long queries, and it
cleans up some bogosity in connection with long EXPLAIN texts anyway.
Note that current libpq will accept any length error message (at least
until it runs out of memory); prior versions have a limit of 8K, but
will cleanly discard excess error text, so there shouldn't be any
big compatibility problems with old clients.

not the process itself. As a result, parent sh gets core dumped in the
