* Further -Wimplicit-fallthrough cleanup.Andres Freund2018-05-01
| | | | | | | | | | | Tom's earlier commit in 41c912cad159 didn't update a few cases that are only encountered with the non-standard --with-llvm config flag. Additionally there's also one case that appears to be a deficiency in gcc's (up to trunk as of a few days ago) detection of "fallthrough" comments - changing the placement slightly fixes that.

* Clean up warnings from -Wimplicit-fallthrough.Tom Lane2018-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | Recent gcc can warn about switch-case fall throughs that are not explicitly labeled as intentional. This seems like a good thing, so clean up the warnings exposed thereby by labeling all such cases with comments that gcc will recognize. In files that already had one or more suitable comments, I generally matched the existing style of those. Otherwise I went with /* FALLTHROUGH */, which is one of the spellings approved at the more-restrictive-than-default level -Wimplicit-fallthrough=4. (At the default level you can also spell it /* FALL ?THRU */, and it's not picky about case. What you can't do is include additional text in the same comment, so some existing comments containing versions of this aren't good enough.) Testing with gcc 8.0.1 (Fedora 28's current version), I found that I also had to put explicit "break"s after elog(ERROR) or ereport(ERROR); apparently, for this purpose gcc doesn't recognize that those don't return. That seems like possibly a gcc bug, but it's fine because in most places we did that anyway; so this amounts to a visit from the style police.

* Fix interaction of foreign tuple routing with remote triggers.Robert Haas2018-05-01
| | | | | | | | | | | | | | | | | | | | | | | | Without these fixes, changes to the inserted tuple made by remote triggers are ignored when building local RETURNING tuples. In the core code, call ExecInitRoutingInfo at a later point from within ExecInitPartitionInfo so that the FDW callback gets invoked after the returning list has been built. But move CheckValidResultRel out of ExecInitRoutingInfo so that it can happen at an earlier stage. In postgres_fdw, refactor assorted deparsing functions to work with the RTE rather than the PlannerInfo, which saves us having to construct a fake PlannerInfo in cases where we don't have a real one. Then, we can pass down a constructed RTE that yields the correct deparse result when no real one exists. Unfortunately, this necessitates a hack that understands how the core code manages RT indexes for update tuple routing, which is ugly, but we don't have a better idea right now. Original report, analysis, and patch by Etsuro Fujita. Heavily refactored by me. Then worked over some more by Amit Langote. Discussion: http://postgr.es/m/5AD4882B.10002@lab.ntt.co.jp

* Does it help to wait before reattaching?Tom Lane2018-04-30
| | | | | | | | | | | | | | | | Revert the map/unmap dance I tried in commit 73042b8d1; that helps not at all. Instead, speculate that the unwanted allocation is being done on another thread, and thus timing variations explain the apparent unpredictability. Temporarily add a 1-second sleep before the VirtualFree call, in hopes that any such other threads will quiesce and not jog our elbow. This is obviously not a desirable long-term fix, but as a means of investigation it seems useful. Discussion: https://postgr.es/m/25495.1524517820@sss.pgh.pa.us
* Map and unmap the shared memory block before risking VirtualFree.Tom Lane2018-04-30
| | | | | | | | | | | | | | The idea here is to get Windows' userspace infrastructure to allocate whatever space it needs for MapViewOfFileEx() before we release the locked-down space that we want to map the shared memory block into. This is a fairly brute-force attempt, and would likely (for example) fail with large shared memory on 32-bit Windows. We could perhaps ameliorate that by mapping only part of the shared memory block in this way, but for the moment I just want to see if this approach will fix dory's problem.

* Get still more info about Windows can't-reattach-to-shared-memory errors.Tom Lane2018-04-29
| | | | | | | | | | | | After some thought about the info captured so far, it seems possible that MapViewOfFileEx is itself causing some DLL to get loaded into the space just freed by VirtualFree. The previous commit here didn't capture enough info to really prove the case for that, so let's add one more VirtualQuery in between those steps. Also, be sure to capture the post-Map state before we emit any log entries, just in case elog() is invoking some code not previously loaded.

* Avoid wrong results for power() with NaN input on more platforms.Tom Lane2018-04-29
| | | | | | | | | | | | | | | Buildfarm results show that the modern POSIX rule that 1 ^ NaN = 1 is not honored on *BSD until relatively recently, and really old platforms don't believe that NaN ^ 0 = 1 either. (This is unsurprising, perhaps, since SUSv2 doesn't require either behavior.) In hopes of getting to platform independent behavior, let's deal with all the NaN-input cases explicitly in dpow(). Note that numeric_power() doesn't know either of these special cases. But since that behavior is platform-independent, I think it should be addressed separately, and probably not back-patched.

* Avoid wrong results for power() with NaN input on some platforms.Tom Lane2018-04-29
| | | | | | | | | | | | | | | Per spec, the result of power() should be NaN if either input is NaN. It appears that on some versions of Windows, the libc function does return NaN, but it also sets errno = EDOM, confusing our code that attempts to work around shortcomings of other platforms. Hence, add guard tests to avoid substituting a wrong result for the right one. It's been like this for a long time (and the odd behavior only appears in older MSVC releases, too) so back-patch to all supported branches.

It's a caller error if something is not explicitly closed by the end of a successful transaction, so issue a WARNING about it.

* Avoid parsing catalog data twice during BKI file construction.Tom Lane2018-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | In the wake of commit 5602265f7, we were doing duplicate-OID detection quite inefficiently, by invoking duplicate_oids which does all the same parsing of catalog headers and .dat files as genbki.pl does. That adds under half a second on modern machines, but quite a bit more on slow buildfarm critters, so it seems worth avoiding. Let's just extend genbki.pl a little so it can also detect duplicate OIDs, and remove the duplicate_oids call from the build process. (This also means that duplicate OID detection will happen during Windows builds, which AFAICS it didn't before.) This makes the use-case for duplicate_oids a bit dubious, but it's possible that people will still want to run that check without doing a whole build run, so let's keep that script. In passing, move down genbki.pl's creation of its temp output files so that it doesn't happen until after we've done parsing and validation of the input. This avoids leaving a lot of clutter around after a failure. John Naylor and Tom Lane Discussion: https://postgr.es/m/37D774E4-FE1F-437E-B3D2-593F314B7505@postgrespro.ru
* Convert unused_oids and duplicate_oids to use Catalog.pm infrastructure.Tom Lane2018-04-25
| | | | | | | | | | | | | | | | | | | unused_oids was previously a shell script, which of course didn't work at all on Windows. Also, commit 372728b0d introduced some other portability problems, as complained of by Stas Kelvich. We can improve matters by converting it to Perl. While we're at it, let's future-proof both this script and duplicate_oids to use Catalog.pm rather than having a bunch of ad-hoc logic for parsing catalog headers and .dat files. These scripts are thereby a bit slower, which doesn't seem like a problem for typical manual use. It is a little annoying for buildfarm purposes, but we should be able to fix that case by having genbki.pl make the check instead of parsing the headers twice. (That's not done in this commit, though.) Stas Kelvich, adjusted a bit by me Discussion: https://postgr.es/m/37D774E4-FE1F-437E-B3D2-593F314B7505@postgrespro.ru

* Add GUC enable_partition_pruningAlvaro Herrera2018-04-23
| | | | | | | | | | | | | | | | | | | | | | This controls both plan-time and execution-time new-style partition pruning. While finer-grain control is possible (maybe using an enum GUC instead of boolean), there doesn't seem to be much need for that. This new parameter controls partition pruning for all queries: trivially, SELECT queries that affect partitioned tables are naturally under its control since they are using the new technology. However, while UPDATE/DELETE queries do not use the new code, we make the new GUC control their behavior also (stealing control from constraint_exclusion), because it is more natural, and it leads to a more natural transition to the future in which those queries will also use the new pruning code. Constraint exclusion still controls pruning for regular inheritance situations (those not involving partitioned tables).

* Fix handling of partition bounds for boolean partitioning columns.Tom Lane2018-04-23
| | | | | | | | | | | | | | | | | Previously, you could partition by a boolean column as long as you spelled the bound values as string literals, for instance FOR VALUES IN ('t'). The trouble with this is that ruleutils.c printed that as FOR VALUES IN (TRUE), which is reasonable syntax but wasn't accepted by the grammar. That results in dump-and-reload failures for such cases. Apply a minimal fix that just causes TRUE and FALSE to be converted to strings 'true' and 'false'. This is pretty grotty, but it's too late for a more principled fix in v11 (to say nothing of v10). We should revisit the whole issue of how partition bound values are parsed for v12. Amit Langote Discussion: https://postgr.es/m/e05c5162-1103-7e37-d1ab-6de3e0afaf70@lab.ntt.co.jp

* Change more places to be less trusting of RestrictInfo.is_pushed_down.Tom Lane2018-04-20
| | | | | | | | | | | | | | | | | | | | | On further reflection, commit e5d83995e didn't go far enough: pretty much everywhere in the planner that examines a clause's is_pushed_down flag ought to be changed to use the more complicated behavior where we also check the clause's required_relids. Otherwise we could make incorrect decisions about whether, say, a clause is safe to use as a hash clause. Some (many?) of these places are safe as-is, either because they are never reached while considering a parameterized path, or because there are additional checks that would reject a pushed-down clause anyway. However, it seems smarter to just code them all the same way rather than rely on easily-broken reasoning of that sort. In support of that, invent a new macro RINFO_IS_PUSHED_DOWN that should be used in place of direct tests on the is_pushed_down flag. Like the previous patch, back-patch to all supported branches.

* Fix incorrect handling of join clauses pushed into parameterized paths.Tom Lane2018-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases a clause attached to an outer join can be pushed down into the outer join's RHS even though the clause is not degenerate --- this can happen if we choose to make a parameterized path for the RHS. If the clause ends up attached to a lower outer join, we'd misclassify it as being a "join filter" not a plain "filter" condition at that node, leading to wrong query results. To fix, teach extract_actual_join_clauses to examine each join clause's required_relids, not just its is_pushed_down flag. (The latter now seems vestigial, or at least in need of rethinking, but we won't do anything so invasive as redefining it in a bug-fix patch.) This has been wrong since we introduced parameterized paths in 9.2, though it's evidently hard to hit given the lack of previous reports. The test case used here involves a lateral function call, and I think that a lateral reference may be required to get the planner to select a broken plan; though I wouldn't swear to that. In any case, even if LATERAL is needed to trigger the bug, it still affects all supported branches, so back-patch to all. Per report from Andreas Karlsson. Thanks to Andrew Gierth for preliminary investigation. Discussion: https://postgr.es/m/f8128b11-c5bf-3539-48cd-234178b2314d@proxel.se
* Remove quick path in ExecInitPartitionInfo for equal tupdescsAlvaro Herrera2018-04-19
| | | | | | | | | | | | I added this "optimization" on top of Amit Langote's 158b7bc6d779, but the quick path is never taken because the partition uses a different pg_type oid than its parent table (causing equalTupleDescs to return false). Changing that requires more analysis and is too considered dangerous at this point in the cycle, so revert it. We might make it work someday, but not for pg11.
