2018-07-30Verify range bounds to bms_add_range when necessaryAlvaro Herrera
Now that the bms_add_range boundary protections are gone, some alternative ones are needed in a few places. Author: Amit Langote <Langote_Amit_f8@lab.ntt.co.jp> Discussion: https://postgr.es/m/3437ccf8-a144-55ff-1e2f-fc16b437823b@lab.ntt.co.jp
2018-07-30Change bms_add_range to be a no-op for empty rangesAlvaro Herrera
In commit 84940644de93, bms_add_range was added with an API to fail with an error if an empty range was specified. This seems arbitrary and unhelpful, so turn that case into a no-op instead. Callers that require further verification on the arguments or result can apply them by themselves. This fixes the bug that partition pruning throws an API error for a case involving the default partition of a default partition, as in the included test case.

2018-07-30Ensure we build generated headers at the start of some more cases.Tom Lane
"make installcheck" and some related cases, when invoked from the toplevel directory, start out by doing "make all" in src/test/regress. Since that's one make recursion level down, the submake-generated-headers target will do nothing, causing us to fail to create/update generated headers before building pg_regress. This is, I believe, a new failure mode induced by commit 3b8f6e75f, so let's fix it. To do so, we have to invoke submake-generated-headers at the top level.

2018-07-29Provide separate header file for built-in float typesTomas Vondra
Some data types under adt/ have separate header files, but most simple ones do not, and their public functions are defined in builtins.h. As the patches improving geometric types will require making additional functions public, this seems like a good opportunity to create a header for floats types. Commit 1acf757255 made _cmp functions public to solve NaN issues locally for GiST indexes. This patch reworks it in favour of a more widely applicable API. The API uses inline functions, as they are easier to use compared to macros, and avoid double-evaluation hazards.

2018-07-29Refactor geometric functions and operatorsTomas Vondra
The primary goal of this patch is to eliminate duplicate code and share code between different geometric data types more often, to prepare the ground for additional patches. Until now the code reuse was limited, probably because the simpler types (line and point) were implemented after the more complex ones. The changes are quite extensive and can be summarised as: * Eliminate SQL-level function calls. * Re-use more functions to implement others. * Unify internal function names and signatures. * Remove private functions from geo_decls.h. * Replace should-not-happen checks with assertions. * Add comments describe for various functions. * Remove some unreachable code. * Define delimiter symbols of line datatype like the other ones. * Remove the GEODEBUG macro and printf() calls. * Unify code style of a few oddly formatted lines. While the goal was to cause minimal user-visible changes, it was not possible to keep the original behavior in all cases - for example when handling NaN values, or when reusing code makes the functions return consistent results.

2018-07-28Reduce path length for locking leaf B-tree pages during insertionAlexander Korotkov
In our B-tree implementation appropriate leaf page for new tuple insertion is acquired using _bt_search() function. This function always returns leaf page locked in shared mode. In order to obtain exclusive lock, caller have to relock the page. This commit makes _bt_search() function lock leaf page immediately in exclusive mode when needed. That removes unnecessary relock and, in turn reduces lock contention for B-tree leaf pages. Our experiments on multi-core systems showed acceleration up to 4.5 times in corner case.

2018-07-27Use key and partdesc from PartitionDispatch where possible.Robert Haas
Instead of repeatedly fishing the data out of the relcache entry, let's use the version that we cached in the PartitionDispatch. We could alternatively rip out the PartitionDispatch fields altogether, but it doesn't make much sense to have them and not use them; before this patch, partdesc was set but altogether unused. Amit Langote and I both thought using them was a litle better than removing them, so this patch takes that approach.

2018-07-27Fix the buffer release order for parallel index scans.Amit Kapila
During parallel index scans, if the current page to be read is deleted, we skip it and try to get the next page for a scan without releasing the buffer lock on the current page. To get the next page, sometimes it needs to wait for another process to complete its scan and advance it to the next page. Now, it is quite possible that the master backend has errored out before advancing the scan and issued a termination signal for all workers. The workers failed to notice the termination request during wait because the interrupts are held due to buffer lock on the previous page. This lead to all workers being stuck. The fix is to release the buffer lock on current page before trying to get the next page. We are already doing same in backward scans, but missed it for forward scans.

2018-07-26Provide plpgsql tests for cases involving record field changes.Tom Lane
We suppressed one of these test cases in commit feb1cc559 because it was failing to produce the expected results on CLOBBER_CACHE_ALWAYS buildfarm members. But now we need another test with similar behavior, so let's set up a test file that is expected to vary between regular and CLOBBER_CACHE_ALWAYS cases, and provide variant expected files. Someday we should fix plpgsql's failure for change-of-field-type, and then the discrepancy will go away and we can fold these tests back into plpgsql_record.sql. But today is not that day.

2018-07-26Avoid crash in eval_const_expressions if a Param's type changes.Tom Lane
Since commit 6719b238e it's been possible for the values of plpgsql record field variables to be exposed to the planner as Params. (Before that, plpgsql never supplied values for such variables during planning, so that the problematic code wasn't reached.) Other places that touch potentially-type-mutable Params either cope gracefully or do runtime-test-and-ereport checks that the type is what they expect. But eval_const_expressions() just had an Assert, meaning that it either failed the assertion or risked crashes due to using an incompatible value. In this case, rather than throwing an ereport immediately, we can just not perform a const-substitution in case of a mismatch. This seems important for the same reason that the Param fetch was speculative: we might not actually reach this part of the expression at runtime. Test case will follow in a separate commit. Patch by me, pursuant to bug report from Andrew Gierth. Back-patch to v11 where the previous commit appeared. Discussion: https://postgr.es/m/87wotkfju1.fsf@news-spur.riddles.org.uk

2018-07-25Add strict_multi_assignment and too_many_rows plpgsql checksTomas Vondra
Until now shadowed_variables was the only plpgsql check supported by plpgsql.extra_warnings and plpgsql.extra_errors. This patch introduces two new checks - strict_multi_assignment and too_many_rows. Unlike shadowed_variables, these new checks are enforced at run-time. strict_multi_assignment checks that commands allowing multi-assignment (for example SELECT INTO) have the same number of sources and targets. too_many_rows checks that queries with an INTO clause return one row exactly. These checks are aimed at cases that are technically valid and allowed, but are often a sign of a bug. Therefore those checks are expected to be enabled primarily in development and testing environments.

2018-07-25Pad semaphores to avoid false sharing.Thomas Munro
In a USE_UNNAMED_SEMAPHORES build, the default on Linux and FreeBSD since commit ecb0d20a, we have an array of sem_t objects. This turned out to reduce performance compared to the previous default USE_SYSV_SEMAPHORES on an 8 socket system.

As benchmarks show, using libc's string-to-integer conversion is pretty slow. At least part of the reason for that is that strtol[l] have to be more generic than what largely is required inside pg. This patch considerably speeds up int2/int4 input (int8 already was already using hand-rolled code). Most of the existing pg_atoi callers have been converted.

2018-07-21Further portability hacking in pg_upgrade's test script.Tom Lane
I blew the dust off a Bourne shell (file date 1996, yea verily) and tried to run test.sh with it. It mostly worked, but I found that the temp-directory creation code introduced by commit be76a6d39 was not compatible, for a couple of reasons: this shell thinks "set -e" should force an exit if a command within backticks fails, and it also thinks code within braces should be executed by a sub-shell, meaning that variable settings don't propagate back up to the parent shell. In view of Victor Wagner's report that Solaris is still using pre-POSIX shells, seems like we oughta make this case work. It's not like the code is any less idiomatic this way; the prior coding technique appeared nowhere else. (There is a remaining bash-ism here, which is that $RANDOM doesn't do what the code hopes in non-bash shells. But the use of $$ elsewhere in that path should be enough to ensure uniqueness and some amount of randomness, so I think it's okay as-is.)

2018-07-20Guard against rare RAND_bytes() failures in pg_strong_random().Dean Rasheed
When built using OpenSSL, pg_strong_random() uses RAND_bytes() to generate the random number. On very rare occasions that can fail, if its PRNG has not been seeded with enough data. Additionally, once it does fail, all subsequent calls will also fail until more seed data is added. Since this is required during backend startup, this can result in all new backends failing to start until a postmaster restart. Guard against that by checking the state of OpenSSL's PRNG using RAND_status(), and if necessary (very rarely), seeding it using RAND_poll().

Also, to prevent pg_upgrade from seeing a non-empty new cluster, exclude pg_largeobject and pg_largeobject_metadata from the set as large object data is handled as user data.
