* Add hint for "invalid byte sequence for encoding" error message,Bruce Momjian2006-08-22

* Get rid of "lookahead" functionality in plpgsql's yylex() function,Tom Lane2006-08-14
| | | | | | | | | | | | | | | | | | | | | | and instead make the grammar production for the RETURN statement do the heavy lifting. The lookahead idea was copied from the main parser, but it does not work in plpgsql's parser because here gram.y looks explicitly at the scanner's yytext variable, which will be out of sync after a failed lookahead step. A minimal example is create or replace function foo() returns void language plpgsql as ' begin perform return foo bar; end'; which can be seen by testing to deliver "foo foo bar" to the main parser instead of the expected "return foo bar". This isn't a huge bug since RETURN is not found in the main grammar, but it could bite someone who tried to use "return" as an identifier. Back-patch to 8.1. Bug exists further back, but HEAD patch doesn't apply cleanly, and given the lack of field complaints it doesn't seem worth the effort to develop adjusted patches.
* Fix core dump in duration logging for a V3-protocol Execute messageTom Lane2006-08-13
| | | | | | when what's being executed is a COMMIT or ROLLBACK. Per report from Sergey Koposov. Backpatch to 8.1; 8.0 and before don't have the bug due to lack of any logging at all here.
* Move Win32 inline define to win32.h so it is found, rather than c.h.Bruce Momjian2006-08-10
| | | | (cleaner)
* Move "#define inline __inline" from port/win32.h to c.h because Win32Bruce Momjian2006-08-10

* Round microseconds on setitimer upwards.Bruce Momjian2006-08-09
|
* On Win32, make minimum setitimer() sleep be 1ms, so sleeps < 1ms aren'tBruce Momjian2006-08-09
| | | | | | rounded down to zero. Backpatch to 8.1.X.
* Fix statement_timeout on Win32 so that it properly treats micro-secondsBruce Momjian2006-08-09
| | | | | | | | as micro-seconds, rather than as 100 microseconds, as it does now. This actually fixes all setitimer calls on Win32, but statement_timeout is the most visible fix. Backpatch to 8.1.X. 8.0 works as documented.
* prevent multiplexing Windows kernel event objects we listen for across ↵Andrew Dunstan2006-07-29
| | | | various sockets - should fix the occasional stats test regression failures we see.
* Fix oversight in sizing of shared buffer lookup hashtable. BecauseTom Lane2006-07-23
| | | | | | | | | BufferAlloc tries to insert a new mapping entry before deleting the old one for a buffer, we have a transient need for more than NBuffers entries --- one more in 8.1, and as many as NUM_BUFFER_PARTITIONS more in CVS HEAD. In theory this could lead to an "out of shared memory" failure if shmem had already been completely claimed by the time the extra entries were needed.
* Hmm, seems --disable-spinlocks has been broken for awhile and nobodyTom Lane2006-07-22
| | | | | noticed. Fix SpinlockSemas() to report the correct count considering that PG 8.1 adds a spinlock to each shared-buffer header.
* Don't try to truncate multixact SLRU files in checkpoints done during xlogTom Lane2006-07-20
| | | | | | | | | | | recovery. In the first place, it doesn't work because slru's latest_page_number isn't set up yet (this is why we've been hearing reports of strange "apparent wraparound" log messages during crash recovery, but only from people who'd managed to advance their next-mxact counters some considerable distance from 0). In the second place, it seems a bit unwise to be throwing away data during crash recovery anwyway. This latter consideration convinces me to just disable truncation during recovery, rather than computing latest_page_number and pushing ahead.
* Ensure that we retry rather than erroring out when send() or recv() returnTom Lane2006-07-16
| | | | | | | | | | | | EINTR; the stats code was failing to do this and so were a couple of places in the postmaster. The stats code assumed that recv() could not return EINTR if a preceding select() showed the socket to be read-ready, but this is demonstrably false with our Windows implementation of recv(), and it may not be the case on all Unix variants either. I think this explains the intermittent stats regression test failures we've been seeing, as well as reports of stats collector instability under high load on Windows. Backpatch as far as 8.0.
* Add dependency to fix parallel-make race condition. Alexander DupuyTom Lane2006-07-14

* Fix ALTER TABLE to check pre-existing NOT NULL constraints when rewritingTom Lane2006-07-10
| | | | | | a table. Otherwise a USING clause that yields NULL can leave the table violating its constraint (possibly there are other cases too). Per report from Alexander Pravking.

* Fix for recent Win32 pg_dump tar temp file patch.Bruce Momjian2006-06-27
| | | | Hiroshi Saito
* On Win32, use loop to create pg_dump temporary tar file in the currentBruce Momjian2006-06-27
| | | | | | directory, not in device root, for permission reasons. Backpatch to 8.1.X.
* Added missing braces to prevent a segfault after usage of an undeclared cursor.Michael Meskes2006-06-26

* Added some more coverity report patches send in by Joachim Wieland ↵Michael Meskes2006-06-26
| | | | <joe@mcknight.de>.
* Tweak dynahash.c to avoid wasting memory space in non-shared hash tables.Tom Lane2006-06-25
| | | | | | | | palloc() will normally round allocation requests up to the next power of 2, so make dynahash choose allocation sizes that are as close to a power of 2 as possible. Back-patch to 8.1 --- the problem exists further back, but a much larger patch would be needed and it doesn't seem worth taking any risks.
* Moved some free() calls that coverity correctly complains about.Michael Meskes2006-06-25
|
* Our version of getopt_long does not set optarg upon detecting an error, asAlvaro Herrera2006-06-25
| | | | | | opposed to what other versions apparently do, so it's not safe to print an error message. Besides, getopt_long itself already did, so it's redundant anyway.
* pg_stop_backup was calling XLogArchiveNotify() twice for the newly createdTom Lane2006-06-22
| | | | | backup history file. Bug introduced by the 8.1 change to make pg_stop_backup delete older history files. Per report from Masao Fujii.
* Disallow aggregate functions in UPDATE commands (unless within a sub-SELECT).Tom Lane2006-06-21
| | | | | | | | This is disallowed by the SQL spec because it doesn't have any very sensible interpretation. Historically Postgres has allowed it but behaved strangely. As of PG 8.1 a server crash is possible if the MIN/MAX index optimization gets applied; rather than try to "fix" that, it seems best to just enforce the spec restriction. Per report from Josh Drake and Alvaro Herrera.
* Added some more coverity report patches send in by Martijn van Oosterhout ↵Michael Meskes2006-06-21

* Added fixes from the coverity report send in by Joachim Wieland ↵Michael Meskes2006-06-21
| | | | | | <joe@mcknight.de> Added missing error handling in a few functions in ecpglib.
* Do not use already free'ed errmsg, bug found by Joachim WielandMichael Meskes2006-06-19
| | | | <joachim.wieland@credativ.de>
* Increase timeout in statement_timeout test from 1 second to 2 seconds.Tom Lane2006-06-18
| | | | | | | | | We have once or twice seen failures suggesting that control didn't get to the exception block before the timeout elapsed, which is unlikely but not impossible in a parallel regression test (with a dozen other backends competing for cycles). This change doesn't completely prevent the problem of course, but it should reduce the probability enough that we don't see it anymore. Per buildfarm results.
* Avoid use of C commment inside C comment from recent Win32 int overflow patch.Bruce Momjian2006-06-12
|
* Win32 can't catch the exception thrown by INT_MIN / -1 or INT_MIN * -1,Bruce Momjian2006-06-12
| | | | | | | so on that platform we test for those before the computation and throw an "out of range" error. Backpatch to 8.1.X.
* Fix Assert failure when a fastpath function call is attempted inside anTom Lane2006-06-11
| | | | | | | | | | | | | | | already-aborted transaction block. GetSnapshotData throws an Assert if not in a valid transaction; hence we mustn't attempt to set a snapshot for the function until after checking for aborted transaction. This is harmless AFAICT if Asserts aren't enabled (GetSnapshotData will compute a bogus snapshot, but it doesn't matter since HandleFunctionRequest will throw an error shortly anywy). Hence, not a major bug. Along the way, add some ability to log fastpath calls when statement logging is turned on. This could probably stand to be improved further, but not logging anything is clearly undesirable. Backpatched as far as 8.0; bug doesn't exist before that.
* Repair remarkably-inefficient query for dumping large object comments: itTom Lane2006-06-09
| | | | | | was invoking obj_description() for each large object chunk, instead of once per large object. This code is new as of 8.1, which may explain why the problem hadn't been noticed already.
* Fix bootstrap.c so that database startup process and bgwriter properly releaseTom Lane2006-06-08
| | | | | | | | | | | | LWLocks during a panic exit. This avoids the possible self-deadlock pointed out by Qingqing Zhou. Also, I noted that an error during LoadFreeSpaceMap() or BuildFlatFiles() would result in exit(0) which would leave the postmaster thinking all is well. Added a critical section to ensure such errors don't allow startup to proceed. Backpatched to 8.1. The 8.0 code is a bit different and I'm not sure if the problem exists there; given we've not seen this reported from the field, I'm going to be conservative about backpatching any further.
* Remove "fuzzy comparison" logic in qsort comparison function forTom Lane2006-06-07
| | | | | | | | | | | | choose_bitmap_and(). It was way too fuzzy --- per comment, it was meant to be 1% relative difference, but was actually coded as 0.01 absolute difference, thus causing selectivities of say 0.001 and 0.000000000001 to be treated as equal. I believe this thinko explains Maxim Boguk's recent complaint. While we could change it to a relative test coded like compare_fuzzy_path_costs(), there's a bigger problem here, which is that any fuzziness at all renders the comparison function non-transitive, which could confuse qsort() to the point of delivering completely wrong results. So forget the whole thing and just do an exact comparison.
