* Have lcov exclude external filesPeter Eisentraut2017-09-28
| | | | | | | Call lcov with --no-external option to exclude external files (for example, system headers with inline functions) from output. Reviewed-by: Michael Paquier <michael.paquier@gmail.com>
* Run only top-level recursive lcovPeter Eisentraut2017-09-28
| | | | | | | | | | | | | | | | This is the way lcov was intended to be used. It is much faster and more robust and makes the makefiles simpler than running it in each subdirectory. The previous coding ran gcov before lcov, but that is useless because lcov/geninfo call gcov internally and use that information. Moreover, this led to complications and failures during parallel make. This separates the two targets: You either use "make coverage" to get textual output from gcov or "make coverage-html" to get an HTML report via lcov. (Using both is still problematic because they write the same output files.) Reviewed-by: Michael Paquier <michael.paquier@gmail.com>
* Fix behavior when converting a float infinity to numeric.Tom Lane2017-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | float8_numeric() and float4_numeric() failed to consider the possibility that the input is an IEEE infinity. The results depended on the platform-specific behavior of sprintf(): on most platforms you'd get something like ERROR: invalid input syntax for type numeric: "inf" but at least on Windows it's possible for the conversion to succeed and deliver a finite value (typically 1), due to a nonstandard output format from sprintf and lack of syntax error checking in these functions. Since our numeric type lacks the concept of infinity, a suitable conversion is impossible; the best thing to do is throw an explicit error before letting sprintf do its thing. While at it, let's use snprintf not sprintf. Overrunning the buffer should be impossible if sprintf does what it's supposed to, but this is cheap insurance against a stack smash if it doesn't. Problem reported by Taiki Kondo. Patch by me based on fix suggestion from KaiGai Kohei. Back-patch to all supported branches.

* Revert to 9.6 treatment of ALTER TYPE enumtype ADD VALUE.Tom Lane2017-09-27
| | | | | | | | | | | | | This reverts commit 15bc038f9, along with the followon commits 1635e80d3 and 984c92074 that tried to clean up the problems exposed by bug #14825. The result was incomplete because it failed to address parallel-query requirements. With 10.0 release so close upon us, now does not seem like the time to be adding more code to fix that. I hope we can un-revert this code and add the missing parallel query support during the v11 cycle. Back-patch to v10. Discussion: https://postgr.es/m/20170922185904.1448.16585@wrigleys.postgresql.org
* Fix plperl buildPeter Eisentraut2017-09-27
| | | | | | | | The changes in 639928c988c1c2f52bbe7ca89e8c7c78a041b3e2 turned out to require Perl 5.9.3, which is newer than our minimum required version. So revert back to the old code for the normal case and only use the new variant when both coverage and vpath are used. As the minimum Perl version moves forward, we can drop the old code sometime.
* Improve vpath support in plperl buildPeter Eisentraut2017-09-27
| | | | | | | | | | | Run xsubpp with the -output option instead of redirecting stdout. That ensures that the #line directives in the output file point to the right place in a vpath build. This in turn fixes an error in coverage builds that it can't find the source files. Refactor the makefile rules while we're here. Reviewed-by: Michael Paquier <michael.paquier@gmail.com>
* pg_basebackup: Add option to create replication slotPeter Eisentraut2017-09-27
| | | | | | | | | | | | When requesting a particular replication slot, the new pg_basebackup option -C/--create-slot creates it before starting to replicate from it. Further refactor the slot creation logic to include the temporary slot creation logic into the same function. Add new arguments is_temporary and preserve_wal to CreateReplicationSlot(). Print in --verbose mode that a slot has been created. Author: Michael Banck <michael.banck@credativ.de>
* Add some more pg_receivewal testsPeter Eisentraut2017-09-26
| | | | | | | Add some more tests for the --create-slot and --drop-slot options, verifying that the right kind of slot was created and that the slot was dropped. While working on an unrelated patch for pg_basebackup, some of this was temporarily broken without any tests noticing.

* Fix failure-to-read-man-page in commit 899bd785c.Tom Lane2017-09-26
| | | | | | | | | | | | | | | | | | | | posix_fallocate() is not quite a drop-in replacement for fallocate(), because it is defined to return the error code as its function result, not in "errno". I (tgl) missed this because RHEL6's version seems to set errno as well. That is not the case on more modern Linuxen, though, as per buildfarm results. Aside from fixing the return-convention confusion, remove the test for ENOSYS; we expect that glibc will mask that for posix_fallocate, though it does not for fallocate. Keep the test for EINTR, because POSIX specifies that as a possible result, and buildfarm results suggest that it can happen in practice. Back-patch to 9.4, like the previous commit.

* Remove heuristic same-transaction test from check_safe_enum_use().Tom Lane2017-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | The blacklist mechanism added by the preceding commit directly fixes most of the practical cases that the same-transaction test was meant to cover. What remains is use-cases like begin; create type e as enum('x'); alter type e add value 'y'; -- use 'y' somehow commit; However, because the same-transaction test is heuristic, it fails on small variants of that, such as renaming the type or changing its owner. Rather than try to explain the behavior to users, let's remove it and just have a rule that the newly added value can't be used before being committed, full stop. Perhaps later it will be worth the implementation effort and overhead to have a more accurate test for type-was-created-in-this-transaction. We'll wait for some field experience with v10 before deciding to do that. Back-patch to v10. Discussion: https://postgr.es/m/20170922185904.1448.16585@wrigleys.postgresql.org
* Use a blacklist to distinguish original from add-on enum values.Tom Lane2017-09-26
| | | | | | | | | | | | | | | | | | | | | | | | Commit 15bc038f9 allowed ALTER TYPE ADD VALUE to be executed inside transaction blocks, by disallowing the use of the added value later in the same transaction, except under limited circumstances. However, the test for "limited circumstances" was heuristic and could reject references to enum values that were created during CREATE TYPE AS ENUM, not just later. This breaks the use-case of restoring pg_dump scripts in a single transaction, as reported in bug #14825 from Balazs Szilfai. We can improve this by keeping a "blacklist" table of enum value OIDs created by ALTER TYPE ADD VALUE during the current transaction. Any visible-but-uncommitted value whose OID is not in the blacklist must have been created by CREATE TYPE AS ENUM, and can be used safely because it could not have a lifespan shorter than its parent enum type. This change also removes the restriction that a renamed enum value can't be used before being committed (unless it was on the blacklist). Andrew Dunstan, with cosmetic improvements by me.

* Sort pg_basebackup options betterPeter Eisentraut2017-09-26
| | | | | | The --slot option somehow ended up under options controlling the output, and some other options were in a nonsensical place or were not moved after recent renamings, so tidy all that up a bit.
* Handle heap rewrites better in logical replicationPeter Eisentraut2017-09-26
| | | | | | | | | | | | | | | | | | | A FOR ALL TABLES publication naturally considers all base tables to be a candidate for replication. This includes transient heaps that are created during a table rewrite during DDL. This causes failures on the subscriber side because it will not have a table like pg_temp_16386 to receive data (and if it did, it would be the wrong table). The prevent this problem, we filter out any tables that match this naming pattern and match an actual table from FOR ALL TABLES publications. This is only a heuristic, meaning that user tables that match that naming could accidentally be omitted. A more robust solution might require an explicit marking of such tables in pg_class somehow.

* Remove lsn from HashScanPosData.Robert Haas2017-09-26
| | | | | | | | | | | | | | | | This was intended as infrastructure for weakening VACUUM's locking requirements, similar to what was done for btree indexes in commit 2ed5b87f96d473962ec5230fd820abfeaccb2069. However, for hash indexes, it seems that the improvements which are possible are actually extremely marginal. Furthermore, performing the LSN cross-check will end up skipping cleanup far more often than is necessary; we only care about page modifications due to a VACUUM, but the LSN check will fail if ANY modification has occurred. So, rather than pressing forward with that "optimization", just rip the LSN field out.

* Avoid SIGBUS on Linux when a DSM memory request overruns tmpfs.Tom Lane2017-09-25
| | | | | | | | | | | | | | | | | | | | | On Linux, shared memory segments created with shm_open() are backed by swap files created in tmpfs. If the swap file needs to be extended, but there's no tmpfs space left, you get a very unfriendly SIGBUS trap. To avoid this, force allocation of the full request size when we create the segment. This adds a few cycles, but none that we wouldn't expend later anyway, assuming the request isn't hugely bigger than the actual need. Make this code #ifdef __linux__, because (a) there's not currently a reason to think the same problem exists on other platforms, and (b) applying posix_fallocate() to an FD created by shm_open() isn't very portable anyway. Back-patch to 9.4 where the DSM code came in. Thomas Munro, per a bug report from Amul Sul Discussion: https://postgr.es/m/1002664500.12301802.1471008223422.JavaMail.yahoo@mail.yahoo.com
* Make construct_[md_]array return a valid empty array for zero-size input.Tom Lane2017-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If construct_array() or construct_md_array() were given a dimension of zero, they'd produce an array that contains no elements but has positive dimension. This violates a general expectation that empty arrays should have ndims = 0; in particular, while arrays like this print as empty, they don't compare equal to other empty arrays. Up to now we've expected callers to avoid making such calls and instead be careful to call construct_empty_array() if there would be no elements. But this has always been an easily missed case, and we've repeatedly had to fix callers to do it right. In bug #14826, Erwin Brandstetter pointed out yet another such oversight, in ts_lexize(); and a bit of examination of other call sites found at least two more with similar issues. So let's fix the problem centrally and permanently by changing these two functions to construct a proper zero-D empty array whenever the array would be empty. This renders a few explicit calls of construct_empty_array() redundant, but the only such place I found that really seemed worth changing was in ExecEvalArrayExpr(). Although this fixes some very old bugs, no back-patch: the problem is pretty minor and the risk of changing behavior seems to outweigh the benefit in stable branches.

| | | | | | | | | | | | There is no reason to ever prevent the use of SortSupport on Windows when ICU locales are used. We previously avoided SortSupport on Windows with UTF-8 server encoding and a non C-locale due to restrictions in Windows' libc functionality. This is now considered to be a restriction in one platform's libc collation provider, and not a more general platform restriction. Reported-by: Peter Geoghegan <pg@bowt.ie>
* Fix pg_basebackup test to original intentPeter Eisentraut2017-09-23
| | | | | | | | | | | | | | One test case was meant to check that pg_basebackup does not succeed when a slot is specified with -S but WAL streaming is not selected, which used to require specifying -X stream. Since -X stream is the default in PostgreSQL 10, this test case no longer covers that meaning, but the pg_basebackup invocation happened to fail anyway for the unrelated reason that the specified replication slot does not exist. To fix, move the test case to later in the file where the slot does exist, and add -X none to the invocation so that it covers the originally meant behavior. extracted from a patch by Michael Banck <michael.banck@credativ.de>

* Refactor new file permission handlingPeter Eisentraut2017-09-23
| | | | | | | | | | | | | | | | | | | The file handling functions from fd.c were called with a diverse mix of notations for the file permissions when they were opening new files. Almost all files created by the server should have the same permissions set. So change the API so that e.g. OpenTransientFile() automatically uses the standard permissions set, and OpenTransientFilePerm() is a new function that takes an explicit permissions set for the few cases where it is needed. This also saves an unnecessary argument for call sites that are just opening an existing file. While we're reviewing these APIs, get rid of the FileName typedef and use the standard const char * for the file name and mode_t for the file mode. This makes these functions match other file handling functions and removes an unnecessary layer of mysteriousness. We can also get rid of a few casts that way.

* Allow up to 3 "-P 1" reports per thread in pgbench run of 2 seconds.Tom Lane2017-09-22
| | | | | | | | | | | | | | | There seems to be some considerable imprecision in the timing of -P progress reports. Nominally each thread ought to produce 2 reports in this test, but about 10% of the time we only get one, and 1% of the time we get three, as per buildfarm results so far. Pending further investigation, treat the last case as a "pass".

* Assume wcstombs(), towlower(), and sibling functions are always present.Tom Lane2017-09-22

Even our oldest buildfarm members have them. Thus, we were not testing the "!USE_WIDE_UPPER_LOWER" code paths, which explains why the bug fixed in commit e6023ee7f escaped detection. Per discussion, there seems to be no more real-world value in maintaining this option. Hence, remove the configure-time tests for wcstombs() and towlower(), remove the USE_WIDE_UPPER_LOWER symbol, and remove all the !USE_WIDE_UPPER_LOWER code.

* Sync our copy of the timezone library with IANA tzcode master.Tom Lane2017-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch absorbs a few unreleased fixes in the IANA code. It corresponds to commit 2d8b944c1cec0808ac4f7a9ee1a463c28f9cd00a in https://github.com/eggert/tz. Non-cosmetic changes include: TZDEFRULESTRING is updated to match current US DST practice, rather than what it was over ten years ago. This only matters for interpretation of POSIX-style zone names (e.g., "EST5EDT"), and only if the timezone database doesn't include either an exact match for the zone name or a "posixrules" entry. The latter should not be true in any current Postgres installation, but this could possibly matter when using --with-system-tzdata. Get rid of a nonportable use of "++var" on a bool var. This is part of a larger fix that eliminates some vestigial support for consecutive leap seconds, and adds checks to the "zic" compiler that the data files do not specify that. Remove a couple of ancient compatibility hacks. The IANA crew think these are obsolete, and I tend to agree. But perhaps our buildfarm will think different. Back-patch to all supported branches, in line with our policy that all branches should be using current IANA code. Before v10, this includes application of current pgindent rules, to avoid whitespace problems in future back-patches. Discussion: https://postgr.es/m/E1dsWhf-0000pT-F9@gemulon.postgresql.org

* Improve dubious memory management in pg_newlocale_from_collation().Tom Lane2017-09-20
| | | | | | | | | | | | | | | | | | | | | pg_newlocale_from_collation() used malloc() and strdup() directly, which is generally not per backend coding style, and it didn't bother to check for failure results, but would just SIGSEGV instead. Also, if one of the numerous error checks in the middle of the function failed, the already-allocated memory would be leaked permanently. Admittedly, it's not a lot of memory, but it could build up if this function were called repeatedly for a bad collation. The first two problems are easily cured by palloc'ing in TopMemoryContext instead of calling libc directly. We can fairly easily dodge the leakage problem for the struct pg_locale_struct by filling in a temporary variable and allocating permanent storage only once we reach the bottom of the function. It's harder to get rid of the potential leakage for ICU's copy of the collcollate string, but at least that's only allocated after most of the error checks; so live with that aspect. Back-patch to v10 where this code came in, with one or another of the ICU patches.
* Fix instability in subscription regression test.Tom Lane2017-09-20
| | | | | | | | | | | 005_encoding.pl neglected to wait for the subscriber's initial synchronization to happen. While we have not seen this fail in the buildfarm, it's pretty easy to demonstrate there's an issue by hacking logicalrep_worker_launch() to fail most of the time.
