Tom Lane	e7dcfd05f3	Apply Tcl_Init() to the "hold" interpreter created by pltcl. ... You might think this is unnecessary since that interpreter is never used to run code --- but it turns out that's wrong. As of Tcl 8.5, the "clock" command (alone among builtin Tcl commands) is partially implemented by loaded-on-demand Tcl code, which means that it fails if there's not unknown-command support, and also that it's impossible to run it directly in a safe interpreter. The way they get around the latter is that Tcl_CreateSlave() automatically sets up an alias command that forwards any execution of "clock" in a safe slave interpreter to its parent interpreter. Thus, when attempting to execute "clock" in trusted pltcl, the command actually executes in the "hold" interpreter, where it will fail if unknown-command support hasn't been introduced by sourcing the standard init.tcl script, which is done by Tcl_Init(). (This is a pretty dubious design decision on the Tcl boys' part, if you ask me ... but they didn't.) Back-patch all the way. It's not clear that anyone would try to use ancient versions of pltcl with a recent Tcl, but it's not clear they wouldn't, either. Also add a regression test using "clock", in branches that have regression test support for pltcl. Per recent trouble report from Kyle Bateman.	16 years ago
Tom Lane	28c480e9ae	Remove unnecessary checkpoint from PL regression tests. This was once ... handy to prevent core dump files from disappearing, but it's useless now because (a) we don't drop core in individual DB subdirectories anymore, and (b) CREATE DATABASE forces an internal checkpoint anyway.	19 years ago
Tom Lane	833f9cb7b8	pltcl regression test needs to actually create an opclass, not just one operator.	19 years ago
Andrew Dunstan	22b118b530	TG_table_name and TG_table_schema for pl/tcl, plus regression test and docs.	20 years ago
Bruce Momjian	bc0be355c8	Adjust PL regression tests for escape_string_warning.	20 years ago
Peter Eisentraut	7f4f42fa10	Clean up CREATE FUNCTION syntax usage in contrib and elsewhere, in ... particular get rid of single quotes around language names and old WITH () construct.	20 years ago
Tom Lane	0ff7a2c2ad	Convert the existing regression test scripts for the various optional ... PLs to use the standard pg_regress infrastructure. No changes in the tests themselves. Andrew Dunstan	21 years ago
Tom Lane	35f4994133	Fix plperl and pltcl error handling per my previous proposal. SPI ... operations are now run as subtransactions, so that errors in them can be reported as ordinary Perl or Tcl errors and caught by the normal error handling convention of those languages. Also do some minor code cleanup in pltcl.c: extract a large chunk of duplicated code in pltcl_SPI_execute and pltcl_SPI_execute_plan into a shared subroutine.	21 years ago
Tom Lane	f9b232f019	Small changes to use the absolute path to system catalogs. ... Greg Sabino Mullane	23 years ago
Tom Lane	78b13fee45	Fix pltcl self-test for recent changes to elog.	24 years ago
Tom Lane	b663f3443b	Add a bunch of pseudo-types to replace the behavior formerly associated ... with OPAQUE, as per recent pghackers discussion. I still want to do some more work on the 'cstring' pseudo-type, but I'm going to commit the bulk of the changes now before the tree starts shifting under me ...	24 years ago
Tom Lane	8b6b414a5e	Update pltcl regress test to exercise return_null; also make use of ... the fact that CREATE FUNCTION and CREATE AGGREGATE now allow array types to be named like int4[] rather than _int4.	26 years ago
Tom Lane	bec98a31c5	Revise aggregate functions per earlier discussions in pghackers. ... There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...	26 years ago
Marc G. Fournier	2784f7c81a	From: Jan Wieck <jwieck@debis.com> ... A few minutes ago I sent down the PL/Tcl directory to this list. Look at it and reuse anything that might help to build PL/perl. I really hope that PL/perl and PL/Tcl appear in the 6.3 distribution. I'll do whatever I can to make this happen.	28 years ago
