* Clean up some problems in error recovery --- elog() was pretty brokenTom Lane1999-11-22
| | | | | | 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.
* Come to think of it, DropBuffers() could have the same problem asTom Lane1999-11-22
| | | | | ReleaseRelationBuffers --- need to wait if anyone is trying to flush out that buffer.
* ReleaseRelationBuffers() failed to check for I/O in progress on a bufferTom Lane1999-11-22
| | | | | | | 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.
* Combine index_info and find_secondary_indexes into a single routine thatTom Lane1999-11-21
| | | | | | | | | 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...
* index_destroy() must grab exclusive access to the parent tableTom Lane1999-11-21
| | | | | | | | | | 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.

* Change backend-side COPY to write files with permissions 644 not 666Tom Lane1999-11-21
| | | | | | | | | (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.
* Repair problem exposed by Jan's new parallel-regression-test scaffold:Tom Lane1999-11-21
| | | | | | | 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.
* Tweak run_check.sh so it prints the name of each test in a parallel groupTom Lane1999-11-21
| | | | | as that test finishes --- helps to give the impression that something is happening...
* My latest fixes to gram.y cause CREATE TABLE t (f1 bool default 1 < 2)Tom Lane1999-11-20
| | | | to be accepted, but constraints regress test was expecting it to fail.
* Fix problems with CURRENT_DATE and related functions being used inTom Lane1999-11-20
| | | | | | | | 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.

* Fix lookup of temp table names that I missed yesterday.Bruce Momjian1999-11-16
|
* Modify elog() logic so that it won't try to longjmp(Warn_restart) beforeTom Lane1999-11-16
| | | | | | | | | | 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.
* Commit to make clearer distinction for temp names and real names.Bruce Momjian1999-11-16

* Tree dividing is not appropriate in Rtree.Tatsuo Ishii1999-11-15
| | | | This fix is reported by Hiroki Kataoka (kataoka@interwiz.koganei.tokyo.jp).
* Clean up possible memory leakage in nodeSubplanTom Lane1999-11-15
|
* Implement subselects in target lists. Also, relax requirement thatTom Lane1999-11-15
| | | | | | | | | | | | | 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.

* Fix ExecSubPlan to handle nulls per the SQL spec --- it didn't combineTom Lane1999-11-12
| | | | | | | 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.
* In the spirit of TODO itemBruce Momjian1999-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add use of 'const' for varibles in source tree (which is misspelled, btw.) I went through the front-end libpq code and did so. This affects in particular the various accessor functions (such as PQdb() and PQgetvalue()) as well as, by necessity, the internal helpers they use. I have been really thorough in that regard, perhaps some people will find it annoying that things like char * foo = PQgetvalue(res, 0, 0) will generate a warning. On the other hand it _should_ generate one. This is no real compatibility break, although a few clients will have to be fixed to suppress warnings. (Which again would be in the spirit of the above TODO.) In addition I replaced some int's by size_t's and removed some warnings (and generated some new ones -- grmpf!). Also I rewrote PQoidStatus (so it actually honors the const!) and supplied a new function PQoidValue that returns a proper Oid type. This is only front-end stuff, none of the communicaton stuff was touched. The psql patch also adds some new consts to honor the new libpq situation, as well as fixes a fatal condition that resulted when using the -V (--version) option and there is no database listening. So, to summarize, the psql you should definitely put in (with or without the libpq). If you think I went too far with the const-mania in libpq, let me know and I'll make adjustments. If you approve it, I will also update the docs. -Peter -- Peter Eisentraut Sernanders vaeg 10:115
