2017-06-21Phase 3 of pgindent updates.Tom Lane
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.

2017-06-21Initial pgindent run with pg_bsd_indent version 2.0.Tom Lane
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.

2017-06-06Clean up latch related code.Andres Freund
The larger part of this patch replaces usages of MyProc->procLatch with MyLatch. The latter works even early during backend startup, where MyProc->procLatch doesn't yet. While the affected code shouldn't run in cases where it's not initialized, it might get copied into places where it might. Using MyLatch is simpler and a bit faster to boot, so there's little point to stick with the previous coding. While doing so I noticed some weaknesses around newly introduced uses of latches that could lead to missed events, and an omitted CHECK_FOR_INTERRUPTS() call in worker_spi. As all the actual bugs are in v10 code, there doesn't seem to be sufficient reason to backpatch this.

2017-06-05Don't be so trusting that shm_toc_lookup() will always succeed.Tom Lane
Given the possibility of race conditions and so on, it seems entirely unsafe to just assume that shm_toc_lookup() always finds the key it's looking for --- but that was exactly what all but one call site were doing. To fix, add a "bool noError" argument, similarly to what we have in many other functions, and throw an error on an unexpected lookup failure. Remove now-redundant Asserts that a rather random subset of call sites had. I doubt this will throw any light on buildfarm member lorikeet's recent failures, because if an unnoticed lookup failure were involved, you'd kind of expect a null-pointer-dereference crash rather than the observed symptom. But you never know ... and this is better coding practice even if it never catches anything. Discussion: https://postgr.es/m/[email protected]

2017-05-11Rename WAL-related functions and views to use "lsn" not "location".Tom Lane
Per discussion, "location" is a rather vague term that could refer to multiple concepts. "LSN" is an unambiguous term for WAL locations and should be preferred. Some function names, view column names, and function output argument names used "lsn" already, but others used "location", as well as yet other terms such as "wal_position". Since we've already renamed a lot of things in this area from "xlog" to "wal" for v10, we may as well incur a bit more compatibility pain and make these names all consistent.

2017-05-02Ensure commands in extension scripts see the results of preceding DDL.Tom Lane
Due to a missing CommandCounterIncrement() call, parsing of a non-utility command in an extension script would not see the effects of the immediately preceding DDL command, unless that command's execution ends with CommandCounterIncrement() internally ... which some do but many don't.

2017-04-22Make PostgresNode::append_conf append a newline automatically.Tom Lane
Although the documentation for append_conf said clearly that it didn't add a newline, many test authors seem to have forgotten that ... or maybe they just consulted the example at the top of the POD documentation, which clearly shows adding a config entry without bothering to add a trailing newline. The worst part of that is that it works, as long as you don't do it more than once, since the backend isn't picky about whether config files end with newlines. So there's not a strong forcing function reminding test authors not to do it like that. Upshot is that this is a terribly fragile way to go about things, and there's at least one existing test case that is demonstrably broken and not testing what it thinks it is. Let's just make append_conf append a newline, instead; that is clearly way safer than the old definition. I also cleaned up a few call sites that were unnecessarily ugly. (I left things alone in places where it's plausible that additional config lines would need to be added someday.) Back-patch the change in append_conf itself to 9.6 where it was added, as having a definitional inconsistency between branches would obviously be pretty hazardous for back-patching TAP tests. The other changes are just cosmetic and don't need to be back-patched. Discussion: https://postgr.es/m/[email protected]
2017-04-17Ensure BackgroundWorker struct contents are well-defined.Tom Lane
Coverity complained because bgw.bgw_extra wasn't being filled in by ApplyLauncherRegister(). The most future-proof fix is to memset the whole BackgroundWorker struct to zeroes.

2017-03-14Improve isolation tests infrastructure.Andres Freund
Previously if a directory had both isolationtester and plain regression tests, they couldn't be run in parallel, because they'd access the same files/directories. That, so far, only affected contrib/test_decoding. Rather than fix that locally in contrib/test_decoding, improve pg_regress_isolation_[install]check to use separate resources from plain regression tests. That requires a minor change in pg_regress, namely that the --outputdir is created if not already existing, that seems like good idea anyway. Use the improved helpers even where previously not used.

This module was intended to ease migrations of applications that used the pre-8.3 version of text search to the in-core version introduced in that release. However, since all pre-8.3 releases of the database have been out of support for more than 5 years at this point, we expect that few people are depending on it at this point.

2017-02-10Add CREATE SEQUENCE AS <data type> clausePeter Eisentraut
This stores a data type, required to be an integer type, with the sequence. The sequences min and max values default to the range supported by the type, and they cannot be set to values exceeding that range. The internal implementation of the sequence is not affected. Change the serial types to create sequences of the appropriate type. This makes sure that the min and max values of the sequence for a serial column match the range of values supported by the table column. So the sequence can no longer overflow the table column. This also makes monitoring for sequence exhaustion/wraparound easier, which currently requires various contortions to cross-reference the sequences with the table columns they are used with. This commit also effectively reverts the pg_sequence column reordering in f3b421da5f4addc95812b9db05a24972b8fd9739, because the new seqtypid column allows us to fill the hole in the struct and create a more natural overall column ordering.

Commit f82ec32ac30ae7e3ec7c84067192535b2ff8ec0e renamed the pg_xlog directory to pg_wal. To make things consistent, and because "xlog" is terrible terminology for either "transaction log" or "write-ahead log" rename all SQL-callable functions that contain "xlog" in the name to instead contain "wal".

To make it look slightly less tragic, I changed most of the independent arguments into long-form single arguments (eg: -f file.sql changed to be --file=file.sql) to avoid having them confusingly split across lines due to perltidy.

2017-01-30Handle ALTER EXTENSION ADD/DROP with pg_init_privsStephen Frost
In commit 6c268df, pg_init_privs was added to track the initial privileges of catalog objects and extensions. Unfortunately, that commit didn't include understanding of ALTER EXTENSION ADD/DROP, which allows the objects associated with an extension to be changed after the initial CREATE EXTENSION script has been run. The result of this meant that ACLs for objects added through ALTER EXTENSION ADD were not recorded into pg_init_privs and we would end up including those ACLs in pg_dump when we shouldn't have. This commit corrects that by making sure to have pg_init_privs updated when ALTER EXTENSION ADD/DROP is run, recording the permissions as they are at ALTER EXTENSION ADD time, and removing any if/when ALTER EXTENSION DROP is called. This issue was pointed out by Moshe Jacobson as commentary on bug #14456 (which was actually a bug about versions prior to 9.6 not handling custom ACLs on extensions correctly, an issue now addressed with pg_init_privs in 9.6). Back-patch to 9.6 where pg_init_privs was introduced.

2017-01-19Dump sequence data based on the TableDataInfo flagStephen Frost
When considering a sequence's Data entry in dumpSequenceData, we were actually looking at the sequence definition's dump flag to decide if we should dump the data or not. That's generally fine, except for when the sequence data entry was created by processExtensionTables() because it's a config sequence. In that case, the sequence itself won't be marked as dumping data because it's part of an extension, leading to the need for processExtensionTables() to create the sequence data entry. This leads to extension config sequence data not being included in the dump when it should be. Fix this by looking at the sequence data's dump flag instead, just as dumpTableData() was doing for tables (which is why config tables were correctly being handled), and add a regression test to make sure we don't break it moving forward. All of this is a bit round-about since we can now represent which components of a given dump item should be dumped out through the dump flag. A future improvement might be to change checkExtensionMembership() to check for config sequences/tables and set the dump flag based on that directly, possibly removing the need for processExtensionTables(). Bug found by Daniele Varrazzo.

2017-01-18Improve RLS planning by marking individual quals with security levels.Tom Lane
In an RLS query, we must ensure that security filter quals are evaluated before ordinary query quals, in case the latter contain "leaky" functions that could expose the contents of sensitive rows. The original implementation of RLS planning ensured this by pushing the scan of a secured table into a sub-query that it marked as a security-barrier view. Unfortunately this results in very inefficient plans in many cases, because the sub-query cannot be flattened and gets planned independently of the rest of the query. To fix, drop the use of sub-queries to enforce RLS qual order, and instead mark each qual (RestrictInfo) with a security_level field establishing its priority for evaluation. Quals must be evaluated in security_level order, except that "leakproof" quals can be allowed to go ahead of quals of lower security_level, if it's helpful to do so. This has to be enforced within the ordering of any one list of quals to be evaluated at a table scan node, and we also have to ensure that quals are not chosen for early evaluation (i.e., use as an index qual or TID scan qual) if they're not allowed to go ahead of other quals at the scan node. This is sufficient to fix the problem for RLS quals, since we only support RLS policies on simple tables and thus RLS quals will always exist at the table scan level only. Eventually these qual ordering rules should be enforced for join quals as well, which would permit improving planning for explicit security-barrier views; but that's a task for another patch. Note that FDWs would need to be aware of these rules --- and not, for example, send an insecure qual for remote execution --- but since we do not yet allow RLS policies on foreign tables, the case doesn't arise. This will need to be addressed before we can allow such policies. Patch by me, reviewed by Stephen Frost and Dean Rasheed. Discussion: https://postgr.es/m/[email protected]

2016-12-02Delete deleteWhatDependsOn() in favor of more performDeletion() flag bits.Tom Lane
deleteWhatDependsOn() had grown an uncomfortably large number of assumptions about what it's used for. There are actually only two minor differences between what it does and what a regular performDeletion() call can do, so let's invent additional bits in performDeletion's existing flags argument that specify those behaviors, and get rid of deleteWhatDependsOn() as such. (We'd probably have done it this way from the start, except that performDeletion didn't originally have a flags argument, IIRC.) Also, add a SKIP_EXTENSIONS flag bit that prevents ever recursing to an extension, and use that when dropping temporary objects at session end. This provides a more general solution to the problem addressed in a hacky way in commit 08dd23cec: if an extension script creates temp objects and forgets to remove them again, the whole extension went away when its contained temp objects were deleted. The previous solution only covered temp relations, but this solves it for all object types. These changes require minor additions in dependency.c to pass the flags to subroutines that previously didn't get them, but it's still a net savings of code, and it seems cleaner than before. Having done this, revert the special-case code added in 08dd23cec that prevented addition of pg_depend records for temp table extension membership, because that caused its own oddities: dropping an extension that had created such a table didn't automatically remove the table, leading to a failure if the table had another dependency on the extension (such as use of an extension data type), or to a duplicate-name failure if you then tried to recreate the extension. But we keep the part that prevents the pg_temp_nnn schema from becoming an extension member; we never want that to happen. Add a regression test case covering these behaviors. Although this fixes some arguable bugs, we've heard few field complaints, and any such problems are easily worked around by explicitly dropping temp objects at the end of extension scripts (which seems like good practice anyway). So I won't risk a back-patch. Discussion: https://postgr.es/m/[email protected]
2016-11-26Fix test about ignoring extension dependencies during extension scripts.Tom Lane
Commit 08dd23cec introduced an exception to the rule that extension member objects can only be dropped as part of dropping the whole extension, intending to allow such drops while running the extension's own creation or update scripts. However, the exception was only applied at the outermost recursion level, because it was modeled on a pre-existing check to ignore dependencies on objects listed in pendingObjects. Bug #14434 from Philippe Beaudoin shows that this is inadequate: in some cases we can reach an extension member object by recursion from another one. (The bug concerns the serial-sequence case; I'm not sure if there are other cases, but there might well be.) To fix, revert 08dd23cec's changes to findDependentObjects() and instead apply the creating_extension exception regardless of stack level. Having seen this example, I'm a bit suspicious that the pendingObjects logic is also wrong and such cases should likewise be allowed at any recursion level. However, changing that would interact in subtle ways with the recursion logic (at least it would need to be moved to after the recursing-from check). Given that the code's been like that a long time, I'll refrain from touching it without a clear example showing it's wrong. Back-patch to all active branches. In HEAD and 9.6, where suitable test infrastructure exists, add a regression test case based on the bug report. Report: <[email protected]> Discussion: <[email protected]>

2016-11-08Change qr/foo$/m to qr/foo\n/m, for Perl 5.8.8.Noah Misch
In each case, absence of a trailing newline would itself constitute a PostgreSQL bug. Therefore, this slightly enhances the changed tests. This works around a bug that last appeared in Perl 5.8.8, fixing src/test/modules/test_pg_dump when run against that version. Commit e7293e3271bf618eeb2d4779a15fc516a69fe463 worked around the bug, but the subsequent addition of test_pg_dump introduced affected code.

This makes it possible to uniquely identify every point in the core code where we are waiting for a latch; extensions can pass WAIT_EXTENSION. Because latches were the major wait primitive not previously covered by this patch, it is now possible to see information in pg_stat_activity on a large number of important wait events not previously addressed, such as ClientRead, ClientWrite, and SyncRep. Unfortunately, many of the wait events added by this patch will fail to appear in pg_stat_activity because they're only used in background processes which don't currently appear in pg_stat_activity.

2016-09-08Fix two src/test/modules MakefilesAlvaro Herrera
commit_ts and test_pg_dump were declaring targets before including the PGXS stanza, which meant that the "all" target customarily defined as the first (and therefore default target) was not the default anymore. Fix that by moving those target definitions to after PGXS. commit_ts was initially good, but I broke it in commit 9def031bd2; test_pg_dump was born broken, probably copying from commit_ts' mistake. In passing, fix a comment mistake in test_pg_dump/Makefile. Backpatch to 9.6. Noted by Tom Lane.
2016-09-08Allow pg_dump to dump non-extension members of an extension-owned schema.Tom Lane
Previously, if a schema was created by an extension, a normal pg_dump run (not --binary-upgrade) would summarily skip every object in that schema. In a case where an extension creates a schema and then users create other objects within that schema, this does the wrong thing: we want pg_dump to skip the schema but still create the non-extension-owned objects. There's no easy way to fix this pre-9.6, because in earlier versions the "dump" status for a schema is just a bool and there's no way to distinguish "dump me" from "dump my members". However, as of 9.6 we do have enough state to represent that, so this is a simple correction of the logic in selectDumpableNamespace. In passing, make some cosmetic fixes in nearby code.
