* Fix memory leakage in ICU encoding conversion, and other code review.Tom Lane2017-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Callers of icu_to_uchar() neglected to pfree the result string when done with it. This results in catastrophic memory leaks in varstr_cmp(), because of our prevailing assumption that btree comparison functions don't leak memory. For safety, make all the call sites clean up leaks, though I suspect that we could get away without it in formatting.c. I audited callers of icu_from_uchar() as well, but found no places that seemed to have a comparable issue. Add function API specifications for icu_to_uchar() and icu_from_uchar(); the lack of any thought-through specification is perhaps not unrelated to the existence of this bug in the first place. Fix icu_to_uchar() to guarantee a nul-terminated result; although no existing caller appears to care, the fact that it would have been nul-terminated except in extreme corner cases seems ideally designed to bite someone on the rear someday. Fix ucnv_fromUChars() destCapacity argument --- in the worst case, that could perhaps have led to a non-nul-terminated result, too. Fix icu_from_uchar() to have a more reasonable definition of the function result --- no callers are actually paying attention, so this isn't a live bug, but it's certainly sloppily designed. Const-ify icu_from_uchar()'s input string for consistency. That is not the end of what needs to be done to these functions, but it's as much as I have the patience for right now.

* Add testing to detect errors of omission in "pin" dependency creation.Tom Lane2017-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's essential that initdb.c's setup_depend() scan each system catalog that could contain objects that need to have "p" (pin) entries in pg_depend or pg_shdepend. Forgetting to add that, either when a catalog is first invented or when it first acquires DATA() entries, is an obvious bug hazard. We can detect such omissions at reasonable cost by probing every OID-containing system catalog to see whether the lowest-numbered OID in it is pinned. If so, the catalog must have been properly accounted for in setup_depend(). If the lowest OID is above FirstNormalObjectId then the catalog must have been empty at the end of initdb, so it doesn't matter. There are a small number of catalogs whose first entry is made later in initdb than setup_depend(), resulting in nonempty expected output of the test, but these can be manually inspected to see that they are OK. Any future mistake of this ilk will manifest as a new entry in the test's output. Since pg_conversion is already in the test's output, add it to the set of catalogs scanned by setup_depend(). That has no effect today (hence, no catversion bump here) but it will protect us if we ever do add pin-worthy conversions. This test is very much like the catalog sanity checks embodied in opr_sanity.sql and type_sanity.sql, but testing pg_depend doesn't seem to fit naturally into either of those scripts' charters. Hence, invent a new test script misc_sanity.sql, which can be a home for this as well as tests on any other catalogs we might want in future.

* Fix typos in README.dependenciesAlvaro Herrera2017-06-22
| | | | | | | | | | | | | | | There was a logic error in a formula, reported by Atsushi Torokoshi. Ashutosh Bapat furthermore recommended to change notation for a variable that was re-using a letter from a previous formula, though his proposed patch contained a small error in attributing what the new letter is for. Also, instead of his proposed d' I ended up using e, to avoid confusing the reader with quotes which are used differently in the explaining prose. Bugs appeared in commit 2686ee1b7ccfb9214064d4d2a98ea77382880306.

* Fix autovacuum launcher attachment to its DSAAlvaro Herrera2017-06-22
| | | | | | | | | | | | | | | | | The autovacuum launcher doesn't actually do anything with its DSA other than creating it and attaching to it, but it's been observed that after longjmp'ing to the standard error handling block (for example after getting SIGINT) the autovacuum enters an infinite loop reporting that it cannot attach to its DSA anymore (which is correct, because it's already attached to it.) Fix by only attempting to attach if not already attached. I introduced this bug together with BRIN autosummarization in 7526e10224f0. Reported-by: Yugo Nagata. Author: Thomas Munro.

* Fix possibility of creating a "phantom" segment after promotion.Andres Freund2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When promoting a standby just after a XLOG_SWITCH record was replayed, and next segment(s) are already are locally available (via walsender, restore_command + trigger/recovery target), that segment could accidentally be recycled onto the past of the new timeline. Later checkpointer would create a .ready file for it, assuming there was an error during creation, and it would get archived. That causes trouble if another standby is later brought up from a basebackup from before the timeline creation, because it would try to read the segment, because XLogFileReadAnyTLI just tries all possible timelines, which doesn't have valid contents. Thus replay would fail. The problem, if already occurred, can be fixed by removing the segment and/or having restore_command filter it out. The reason for the creation of such "phantom" segments was, that after an XLOG_SWITCH record the EndOfLog variable points to the beginning of the next segment, and RemoveXlogFile() used XLByteToPrevSeg(). Normally RemoveXlogFile() doing so is harmless, because the last segment will still exist preventing InstallXLogFileSegment() from causing harm, but just after promotion there's no previous segment on the new timeline. Fix that by using XLByteToSeg() instead of XLByteToPrevSeg().

* Phase 3 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Phase 2 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change pg_bsd_indent to follow upstream rules for placement of comments to the right of code, and remove pgindent hack that caused comments following #endif to not obey the general rule. Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using the published version of pg_bsd_indent, but a hacked-up version that tried to minimize the amount of movement of comments to the right of code. The situation of interest is where such a comment has to be moved to the right of its default placement at column 33 because there's code there. BSD indent has always moved right in units of tab stops in such cases --- but in the previous incarnation, indent was working in 8-space tab stops, while now it knows we use 4-space tabs. So the net result is that in about half the cases, such comments are placed one tab stop left of before. This is better all around: it leaves more room on the line for comment text, and it means that in such cases the comment uniformly starts at the next 4-space tab stop after the code, rather than sometimes one and sometimes two tabs after. Also, ensure that comments following #endif are indented the same as comments following other preprocessor commands such as #else. That inconsistency turns out to have been self-inflicted damage from a poorly-thought-through post-indent "fixup" in pgindent. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Initial pgindent run with pg_bsd_indent version 2.0.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new indent version includes numerous fixes thanks to Piotr Stefaniak. The main changes visible in this commit are: * Nicer formatting of function-pointer declarations. * No longer unexpectedly removes spaces in expressions using casts, sizeof, or offsetof. * No longer wants to add a space in "struct structname *varname", as well as some similar cases for const- or volatile-qualified pointers. * Declarations using PG_USED_FOR_ASSERTS_ONLY are formatted more nicely. * Fixes bug where comments following declarations were sometimes placed with no space separating them from the code. * Fixes some odd decisions for comments following case labels. * Fixes some cases where comments following code were indented to less than the expected column 33. On the less good side, it now tends to put more whitespace around typedef names that are not listed in typedefs.list. This might encourage us to put more effort into typedef name collection; it's not really a bug in indent itself. There are more changes coming after this round, having to do with comment indentation and alignment of lines appearing within parentheses. I wanted to limit the size of the diffs to something that could be reviewed without one's eyes completely glazing over, so it seemed better to split up the changes as much as practical.

* Adjust pgindent script to use pg_bsd_indent 2.0.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | Update version-checking code and list of switches. Delete obsolete quasi-support for using GNU indent. Remove a lot of no-longer-needed workarounds for bugs of the old version, and improve comments for the hacks that remain. Update run_build() subroutine to fetch the pg_bsd_indent code from the newly established git repo for it. In passing, fix pgindent to not overwrite files that require no changes; this makes it a bit more friendly to run on a built tree. Adjust relevant documentation. Remove indent.bsd.patch; it's not relevant anymore (and was obsolete long ago anyway). Likewise remove pgcppindent, since we're no longer in the business of shipping C++ code. Piotr Stefaniak is responsible for most of the algorithmic changes to the pgindent script; I did the rest.

| | | | | | | | | | | | | Currently, there are no built-in functions that are SECURITY DEFINER.

* pg_upgrade: start/stop new server after pg_resetwalBruce Momjian2017-06-20
| | | | | | | | | | | | | | | | | | When commit 0f33a719fdbb5d8c43839ea0d2c90cd03e2af2d2 removed the instructions to start/stop the new cluster before running rsync, it was now possible for pg_resetwal/pg_resetxlog to leave the final WAL record at wal_level=minimum, preventing upgraded standby servers from reconnecting. This patch fixes that by having pg_upgrade unconditionally start/stop the new cluster after pg_resetwal/pg_resetxlog has run. Backpatch through 9.2 since, though the instructions were added in PG 9.5, they worked all the way back to 9.2.

* Don't downcase entries within shared_preload_libraries et al.Tom Lane2017-06-20
| | | | | | | | | | | | | | | | | | load_libraries(), which processes the various xxx_preload_libraries GUCs, was parsing them using SplitIdentifierString() which isn't really appropriate for values that could be path names: it downcases unquoted text, and it doesn't allow embedded whitespace unless quoted. Use SplitDirectoriesString() instead. That also allows us to simplify load_libraries() a bit, since canonicalize_path() is now done for it. While this definitely seems like a bug fix, it has the potential to break configuration settings that accidentally worked before because of the downcasing behavior. Also, there's an easy workaround for the bug, namely to double-quote troublesome text. Hence, no back-patch.

* Tweak publication fetching in psqlPeter Eisentraut2017-06-20
| | | | | | | | | | | | | | | | | Viewing a table with \d in psql also shows the publications at table is in. If a publication is concurrently dropped, this shows an error, because the view pg_publication_tables internally uses pg_get_publication_tables(), which uses a catalog snapshot. This can be particularly annoying if a for-all-tables publication is concurrently dropped. To avoid that, write the query in psql differently. Expose the function pg_relation_is_publishable() to SQL and write the query using that. That still has a risk of being affected by concurrent catalog changes, but in this case it would be a table drop that causes problems, and then the psql \d command wouldn't be interesting anymore anyway.

* Avoid regressions in foreign-key-based selectivity estimates.Tom Lane2017-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | David Rowley found that the "use the smallest per-column selectivity" heuristic applied in some cases by get_foreign_key_join_selectivity() was badly off if the FK columns are independent, producing estimates much worse than we got before that code was added in 9.6. One case where that heuristic was used was for LEFT and FULL outer joins with the referenced rel on the outside of the join. But we should not really need to special-case those here. eqjoinsel() never has had such a special case; the correction is applied by calc_joinrel_size_estimate() instead. Let's just estimate such cases like inner joins and rely on that later adjustment. (I think there was something of a thinko here, in that the comments seem to be thinking about the selectivity as defined for semi/anti joins; but that shouldn't apply to left/full joins.) Add a regression test exercising such a case to show that this is sane in at least some cases. The other case where we used that heuristic was for SEMI/ANTI outer joins, either if the referenced rel was on the outside, or if it was on the inside but was part of a join within the RHS. In either case, the FK doesn't give us a lot of traction towards estimating the selectivity. To ensure that we don't have regressions from what happened before 9.6, let's punt by ignoring the FK in such cases and applying the traditional selectivity calculation. (We might be able to improve on that later, but for now I just want to be sure it's not worse than 9.5.) Report and patch by David Rowley, simplified a bit by me.

* Teach pgindent to skip files generated by bison or flex automatically.Tom Lane2017-06-16
| | | | | | | | | | | | | | | | | If a .c or .h file corresponds to a .y or .l file, skip indenting it. There's no point in reindenting derived files, and these files tend to confuse pgindent. (Which probably indicates a bug in BSD indent, but I can't get excited about trying to fix it.) For the same reasons, add src/backend/utils/fmgrtab.c to the set of files excluded by src/tools/pgindent/exclude_file_patterns. The point of doing this is that it makes it safe to run pgindent over the tree without doing "make maintainer-clean" first. While these are not the only derived .c/.h files in the tree, they are the only ones pgindent fails on. Removing that prerequisite step results in one less way to mess up a pgindent run, and it's necessary if we ever hope to get to the ease of running pgindent via "make indent".
