* Oops, fix misspelled #endifHeikki Linnakangas2015-04-14
| | | | I hope this fixes the Windows builfarm failures.
* Try to fix the CRC-32C autoconf magic for icc compiler.Heikki Linnakangas2015-04-14
| | | | | | | | | | | | | On gcc and clang, the _mm_crc32_u8 and _mm_crc32_u64 intrinsics are not defined at all, when not building with -msse4.2. But on icc, they are. So we cannot assume that if those intrinsics are defined, we can always use them safely, we might still need the runtime check. To fix, check if the __SSE_4_2__ preprocessor symbol is defined. That's supposed to be defined only when the compiler is targeting a processor that has SSE 4.2 support. Per buildfarm members fulmar and okapi.
* Fix typo in commentAlvaro Herrera2015-04-14
| | | | | | | | SLRU_SEGMENTS_PER_PAGE -> SLRU_PAGES_PER_SEGMENT I introduced this ancient typo in subtrans.c and later propagated it to multixact.c. I fixed the latter in f741300c, but only back to 9.3; backpatch to all supported branches for consistency.
* Use Intel SSE 4.2 CRC instructions where available.Heikki Linnakangas2015-04-14
| | | | | | | | | | | | | | | | | | Modern x86 and x86-64 processors with SSE 4.2 support have special instructions, crc32b and crc32q, for calculating CRC-32C. They greatly speed up CRC calculation. Whether the instructions can be used or not depends on the compiler and the target architecture. If generation of SSE 4.2 instructions is allowed for the target (-msse4.2 flag on gcc and clang), use them. If they are not allowed by default, but the compiler supports the -msse4.2 flag to enable them, compile just the CRC-32C function with -msse4.2 flag, and check at runtime whether the processor we're running on supports it. If it doesn't, fall back to the slicing-by-8 algorithm. (With the common defaults on current operating systems, the runtime-check variant is what you get in practice.)

* Reorganize our CRC source files again.Heikki Linnakangas2015-04-14
| | | | | | | | | | Now that we use CRC-32C in WAL and the control file, the "traditional" and "legacy" CRC-32 variants are not used in any frontend programs anymore. Move the code for those back from src/common to src/backend/utils/hash. Also move the slicing-by-8 implementation (back) to src/port. This is in preparation for next patch that will add another implementation that uses Intel SSE 4.2 instructions to calculate CRC-32C, where available.

* Fix pg_rewind regression tests in VPATH buildsHeikki Linnakangas2015-04-13

* Refactor and fix TAP tests of pg_rewindHeikki Linnakangas2015-04-13
| | | | | | | | | | | | | | | | | | * Don't pass arguments to prove, since that's not supported on perl 5.8 which is the minimum version supported by the TAP tests. Refactor the test files themselves to run the tests twice, in both local and remote mode. * Use eq rather than == for string comparison. This thinko caused the remote versions of the tests to never run. * Add "use strict" and "use warnings", and fix warnings that that produced. * Increase the delay after standby promotion, to make the tests more robust. * In remote mode, the connection string to the promoted standby was incorrect, leading to connection errors. Patch by Michael Paquier, to address Peter Eisentraut's report.
* Don't archive bogus recycled or preallocated files after timeline switch.Heikki Linnakangas2015-04-13
| | | | | | | | | | | | | | | | | | | After a timeline switch, we would leave behind recycled WAL segments that are in the future, but on the old timeline. After promotion, and after they become old enough to be recycled again, we would notice that they don't have a .ready or .done file, create a .ready file for them, and archive them. That's bogus, because the files contain garbage, recycled from an older timeline (or prealloced as zeros). We shouldn't archive such files. This could happen when we're following a timeline switch during replay, or when we switch to new timeline at end-of-recovery. To fix, whenever we switch to a new timeline, scan the data directory for WAL segments on the old timeline, but with a higher segment number, and remove them. Those don't belong to our timeline history, and are most likely bogus recycled or preallocated files. They could also be valid files that we streamed from the primary ahead of time, but in any case, they're not needed to recover to the new timeline.

* Optimize locking a tuple already locked by another subxactAlvaro Herrera2015-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Locking and updating the same tuple repeatedly led to some strange multixacts being created which had several subtransactions of the same parent transaction holding locks of the same strength. However, once a subxact of the current transaction holds a lock of a given strength, it's not necessary to acquire the same lock again. This made some coding patterns much slower than required. The fix is twofold. First we change HeapTupleSatisfiesUpdate to return HeapTupleBeingUpdated for the case where the current transaction is already a single-xid locker for the given tuple; it used to return HeapTupleMayBeUpdated for that case. The new logic is simpler, and the change to pgrowlocks is a testament to that: previously we needed to check for the single-xid locker separately in a very ugly way. That test is simpler now. As fallout from the HTSU change, some of its callers need to be amended so that tuple-locked-by-own-transaction is taken into account in the BeingUpdated case rather than the MayBeUpdated case. For many of them there is no difference; but heap_delete() and heap_update now check explicitely and do not grab tuple lock in that case. The HTSU change also means that routine MultiXactHasRunningRemoteMembers introduced in commit 11ac4c73cb895 is no longer necessary and can be removed; the case that used to require it is now handled naturally as result of the changes to heap_delete and heap_update. The second part of the fix to the performance issue is to adjust heap_lock_tuple to avoid the slowness: 1. Previously we checked for the case that our own transaction already held a strong enough lock and returned MayBeUpdated, but only in the multixact case. Now we do it for the plain Xid case as well, which saves having to LockTuple. 2. If the current transaction is the only locker of the tuple (but with a lock not as strong as what we need; otherwise it would have been caught in the check mentioned above), we can skip sleeping on the multixact, and instead go straight to create an updated multixact with the additional lock strength. 3. Most importantly, make sure that both the single-xid-locker case and the multixact-locker case optimization are applied always. We do this by checking both in a single place, rather than them appearing in two separate portions of the routine -- something that is made possible by the HeapTupleSatisfiesUpdate API change. Previously we would only check for the single-xid case when HTSU returned MayBeUpdated, and only checked for the multixact case when HTSU returned BeingUpdated. This was at odds with what HTSU actually returned in one case: if our own transaction was locker in a multixact, it returned MayBeUpdated, so the optimization never applied. This is what led to the large multixacts in the first place. Per bug report #8470 by Oskari Saarenmaa.

| | | | | | | | | | | | | When certain event-trigger-only functions are called when not in the wrong context, they were reporting the "feature not supported" SQLSTATE, which is somewhat misleading.

* Fix autovacuum launcher shutdown sequenceAlvaro Herrera2015-04-08
| | | | | | | | | | | | | | | It was previously possible to have the launcher re-execute its main loop before shutting down if some other signal was received or an error occurred after getting SIGTERM, as reported by Qingqing Zhou. While investigating, Tom Lane further noticed that if autovacuum had been disabled in the config file, it would misbehave by trying to start a new worker instead of bailing out immediately -- it would consider itself as invoked in emergency mode. Fix both problems by checking the shutdown flag in a few more places. These problems have existed since autovacuum was introduced, so backpatch all the way back.

* pg_event_trigger_dropped_objects: add is_temp columnAlvaro Herrera2015-04-06
| | | | | | | | | | It now also reports temporary objects dropped that are local to the backend. Previously we weren't reporting any temp objects because it was deemed unnecessary; but as it turns out, it is necessary if we want to keep close track of DDL command execution inside one session. Temp objects are reported as living in schema pg_temp, which works because such a schema-qualification always refers to the temp objects of the current session.

* Suppress clang's unhelpful gripes about -pthread switch being unused.Tom Lane2015-04-05
| | | | | | | | | | | | | Considering the number of cases in which "unused" command line arguments are silently ignored by compilers, it's fairly astonishing that anybody thought this warning was useful; it's certainly nothing but an annoyance when building Postgres. One such case is that neither gcc nor clang complain about unrecognized -Wno-foo switches, making it more difficult to figure out whether the switch does anything than one could wish. Back-patch to 9.3, which is as far back as the patch applies conveniently (we'd have to back-patch PGAC_PROG_CC_VAR_OPT to go further, and it doesn't seem worth that).

* Fix incorrect matching of subexpressions in outer-join plan nodes.Tom Lane2015-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we would re-use input subexpressions in all expression trees attached to a Join plan node. However, if it's an outer join and the subexpression appears in the nullable-side input, this is potentially incorrect for apparently-matching subexpressions that came from above the outer join (ie, targetlist and qpqual expressions), because the executor will treat the subexpression value as NULL when maybe it should not be. The case is fairly hard to hit because (a) you need a non-strict subexpression (else NULL is correct), and (b) we don't usually compute expressions in the outputs of non-toplevel plan nodes. But we might do so if the expressions are sort keys for a mergejoin, for example. Probably in the long run we should make a more explicit distinction between Vars appearing above and below an outer join, but that will be a major planner redesign and not at all back-patchable. For the moment, just hack set_join_references so that it will not match any non-Var expressions coming from nullable inputs to expressions that came from above the join. (This is somewhat overkill, in that a strict expression could still be matched, but it doesn't seem worth the effort to check that.) Per report from Qingqing Zhou. The added regression test case is based on his example. This has been broken for a very long time, so back-patch to all active branches.
* Fix TAP tests to use only standard command-line argument ordering.Tom Lane2015-04-04
| | | | | | | | | | | | | Some of the TAP tests were supposing that PG programs would accept switches after non-switch arguments on their command lines. While GNU getopt_long() does allow that, our own implementation does not, and it's nowhere suggested in our documentation that such cases should work. Adjust the tests to use only the documented syntax. Back-patch to 9.4, since without this the TAP tests fail when run with src/port's getopt_long() implementation. Michael Paquier
* Fix numeric abbreviation for --disable-float8-byval.Robert Haas2015-04-03
| | | | | | | | | | When committing abd94bcac4582903765be7be959d1dbc121df0d0, I tried to make it decide what kind of abbreviation to use based only on SIZEOF_DATUM, without regard to USE_FLOAT8_BYVAL. That attempt was a few bricks short of a load, so try to fix it, and add a comment explaining what we're about. Patch by me; review (but not a full endorsement) by Andrew Gierth.
