[HACKERS] Re: Interesting failure mode for initdb
Tom Lane writes: I think one part of the fix is to modify elog() so that a FATAL exit results in exit status 1, not 0, if not IsUnderPostmaster. Right. At the very least we should hack initdb so that --debug removes "-o /dev/null" from PGSQL_OPT, but can you see any way to provide filtered stderr output from the backend in the normal mode of operation? I've removed some of the /dev/null's and the only undesired output I get is of this form: Enabling unlimited row width for system tables.

I said: That stuff comes out on stdout; all of the interesting stuff is on stderr. Actually, given the -o option all of the interesting stuff will go to wherever -o says. At this stage of the release cycle I suppose we must resist the temptation to define -o '|command' as doing a popen(), but maybe for 7.2 something could be done with "-o '|grep -v ^DEBUG'" ... regards, tom lane ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])

Still the conclusion seems pretty clear: the open() options are way more efficient than calling fsync() separately. regards, tom lane ---(end of broadcast)--- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
[HACKERS] doxygen PG
Is this page http://members.fortunecity.com/nymia/postgres/dox/backend/html/ common knowledge? It appears to be an automatically-generated cross-reference documentation web site. My impression is that appropriately-marked comments in the code get extracted to the web pages, too, so it is also a way to automate internal documentation.

Re: [HACKERS] doxygen PG
The site mentioned was created by me. I used doxygen to create those html files. And it's just the first stab. It doesn't have have doxygen tags yet that's why it looks like that. The reason why I made it was to make it easier for me ( and others as well ) to read the code though. So far, I've learned a lot using this technique.

[HACKERS] Do we still need PowerPC-specific timestamp_is_current/epoch?
At the end of backend/utils/adt/datetime.c, there is some fairly ugly code that is conditionally compiled on #if defined(linux) defined(__powerpc__) Do we still need this? The standard versions of TIMESTAMP_IS_CURRENT and TIMESTAMP_IS_EPOCH appear to work just fine on my Powerbook G3 running Linux 2.2.18 (LinuxPPC 2000 Q4 distro). I see from the CVS logs that Tatsuo originally introduced this code on 1997/07/29 (at the time it lived in dt.c and was called datetime_is_current datetime_is_epoch). I suppose that it must have been meant to work around some bug in old versions of gcc for PPC. But it seems to me to be a net decrease in portability --- it's assuming that the symbolic constants DBL_MIN and -DBL_MIN will produce particular bit patterns --- so I'd like to remove it unless someone knows of a recent Linux/PPC release that still needs it. regards, tom lane ---(end of broadcast)--- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
