Tom Lane	b04bdf1290	Reduce ReleaseLruFile failure from FATAL to ERROR grade; offhand I don't see that this should be a worse way to fail to open a file than any other.	26 years ago
Tom Lane	d831990167	verify_password() leaked a file descriptor if it failed to find the given userid in the flat password file. Do it enough times and the postmaster panicked :-(	26 years ago

Tom Lane	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 discussions on pghackers around 11/6/99.	26 years ago
Tom Lane	bb203c75a9	Come to think of it, DropBuffers() could have the same problem as ReleaseRelationBuffers --- need to wait if anyone is trying to flush out that buffer.	26 years ago
Tom Lane	6b5d8e14b4	ReleaseRelationBuffers() failed to check for I/O in progress on a buffer it wants to release. This leads to a race condition: does the backend that's trying to flush the buffer do so before the one that's deleting the relation does so? Usually no problem, I expect, but on occasion this could lead to hard-to-reproduce complaints from md.c, especially mdblindwrt.	26 years ago
Tom Lane	610dfa6d55	Combine index_info and find_secondary_indexes into a single routine that returns a list of RelOptInfos, eliminating the need for static state in index_info. That static state was a direct cause of coredumps; if anything decided to elog(ERROR) partway through an index_info search of pg_index, the next query would try to close a scan pointer that was pointing at no-longer-valid memory. Another example of the reasons to avoid static state variables...	26 years ago
Tom Lane	40d3e92541	index_destroy() must grab exclusive access to the parent table of the index it wants to destroy. This ensures that no other backend is actively scanning or updating that index. Getting exclusive access on the index alone is NOT sufficient, because the executor is rather cavalier about getting locks on indexes --- see ExecOpenIndices(). It might be better to grab index locks in the executor, but I'm not sure the extra lockmanager traffic is really worth it just to make index_destroy cleaner.	26 years ago
Tom Lane	3047b444e8	Clean up comments.	26 years ago
Tom Lane	d8ba3dfb0b	Change backend-side COPY to write files with permissions 644 not 666 (whoever thought world-writable files were a good default????). Modify the pg_pwd code so that pg_pwd is created with 600 permissions. Modify initdb so that permissions on a pre-existing PGDATA directory are not blindly accepted: if the dir is already there, it does chmod go-rwx to be sure that the permissions are OK and the dir actually is owned by postgres.	26 years ago
Tom Lane	76ccf73f2b	Repair problem exposed by Jan's new parallel-regression-test scaffold: inval.c thought it could safely use the catcache to look up the OIDs of system relations. Not good, considering that inval.c could be called during catcache loading, if a shared-inval message arrives. Rip out the lookup logic and instead use the known OIDs from pg_class.h.	26 years ago
Tom Lane	9ba0172f41	Tweak run_check.sh so it prints the name of each test in a parallel group as that test finishes --- helps to give the impression that something is happening...	26 years ago
Tom Lane	79f39c4d34	My latest fixes to gram.y cause CREATE TABLE t (f1 bool default 1 < 2) to be accepted, but constraints regress test was expecting it to fail.	26 years ago
Tom Lane	ea4ae10849	Fix problems with CURRENT_DATE and related functions being used in table defaults or rules: translate them to a function call so that parse_coerce doesn't reduce them to a date or time constant immediately. Also, eliminate a lot of redundancy in the expression grammar by defining a new nonterminal com_expr, which contains all the productions that can be shared by a_expr and b_expr.	26 years ago
Tom Lane	3267e2978f	Fix a couple of portability problems in Jan's first-cut parallel test script. This is way cool...	26 years ago

Jan Wieck	79c3b71c1b	The new LZ compression and an lztext data type based on it. Jan	26 years ago
Bruce Momjian	ddc335290c	Fix lookup of temp table names that I missed yesterday.	26 years ago
Tom Lane	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.	26 years ago
Bruce Momjian	dc5c7713bc	Commit to make clearer distinction for temp names and real names. Thanks to Tom Lane for ideas.	26 years ago
Tatsuo Ishii	bf5d51e7fe	Tree dividing is not appropriate in Rtree. This fix is reported by Hiroki Kataoka (kataoka@interwiz.koganei.tokyo.jp).	26 years ago
Tom Lane	c8c3e07e58	Clean up possible memory leakage in nodeSubplan	26 years ago
Tom Lane	f68e11f373	Implement subselects in target lists. Also, relax requirement that subselects can only appear on the righthand side of a binary operator. That's still true for quantified predicates like x = ANY (SELECT ...), but a subselect that delivers a single result can now appear anywhere in an expression. This is implemented by changing EXPR_SUBLINK sublinks to represent just the (SELECT ...) expression, without any 'left hand side' or combining operator --- so they're now more like EXISTS_SUBLINK. To handle the case of '(x, y, z) = (SELECT ...)', I added a new sublink type MULTIEXPR_SUBLINK, which acts just like EXPR_SUBLINK used to. But the grammar will only generate one for a multiple-left-hand-side row expression.	26 years ago

Bruce Momjian	db12a63ef1	The \p\g fix didn't turn out to be so bad. It even works in other circumstances: => select * from foo\x\t\pset border 0 \p\g\\select * from bar; Also the release prep update so the sql_help.h is generated before packaging. Peter.	26 years ago
Bruce Momjian	d286f13b47	Update NT readme with new name.	26 years ago
Tom Lane	ac61a04a71	Fix ExecSubPlan to handle nulls per the SQL spec --- it didn't combine nulls with non-nulls using proper three-valued boolean logic. Also clean up ExecQual to make it clearer that ExecQual does follow the SQL spec for boolean nulls. See '[BUGS] (null) != (null)' thread around 10/26/99 for more detail.	26 years ago
