2024-11-27ecpg: clean up some other assorted memory leaks.Tom Lane
Avoid leaking the prior value when updating the "connection" state variable. Ditto for ECPGstruct_sizeof. (It seems like this one ought to be statement-local, but testing says it isn't, and I didn't feel like diving deeper.) The actual_type[] entries are statement-local, though, so no need to mm_strdup() strings stored in them. Likewise, sqlda variables are statement-local, so we can loc_alloc them. Also clean up sloppiness around management of the argsinsert and argsresult lists. progname changes are strictly to prevent valgrind from complaining about leaked allocations. With this, valgrind reports zero leakage in the ecpg preprocessor for all of our ecpg regression test cases. Discussion: https://postgr.es/m/2011420.1713493114@sss.pgh.pa.us
2024-11-27ecpg: put all string-valued tokens returned by pgc.l in local storage.Tom Lane

2024-11-27ecpg: fix some memory leakage of data-type-related structures.Tom Lane
ECPGfree_type() and related functions were quite incomplete about removing subsidiary data structures. Possibly this is because ecpg wasn't careful to make sure said data structures always had their own storage. Previous patches in this series cleaned up a lot of that, and I had to add a couple more mm_strdup's here. Also, ecpg.trailer tended to overwrite struct_member_list[struct_level] without bothering to free up its previous contents, thus potentially leaking a lot of struct-member-related storage. Add ECPGfree_struct_member() calls at appropriate points. Discussion: https://postgr.es/m/2011420.1713493114@sss.pgh.pa.us
2024-11-27jsonapi: add lexer option to keep token ownershipAndrew Dunstan
Commit 0785d1b8b adds support for libpq as a JSON client, but allocations for string tokens can still be leaked during parsing failures. This is tricky to fix for the object_field semantic callbacks: the field name must remain valid until the end of the object, but if a parsing error is encountered partway through, object_field_end() won't be invoked and the client won't get a chance to free the field name. This patch adds a flag to switch the ownership of parsed tokens to the lexer. When this is enabled, the client must make a copy of any tokens it wants to persist past the callback lifetime, but the lexer will handle necessary cleanup on failure. Backend uses of the JSON parser don't need to use this flag, since the parser's allocations will occur in a short lived memory context. A -o option has been added to test_json_parser_incremental to exercise the new setJsonLexContextOwnsTokens() API, and the test_json_parser TAP tests make use of it. (The test program now cleans up allocated memory, so that tests can be usefully run under leak sanitizers.)

2024-11-27Look up backend type in pg_signal_backend() more cheaply.Nathan Bossart
Commit ccd38024bc, which introduced the pg_signal_autovacuum_worker role, added a call to pgstat_get_beentry_by_proc_number() for the purpose of determining whether the process is an autovacuum worker. This function calls pgstat_read_current_status(), which can be fairly expensive and may return cached, out-of-date information. Since we just need to look up the target backend's BackendType, and we already know its ProcNumber, we can instead inspect the BackendStatusArray directly, which is much less expensive and possibly more up-to-date. There are some caveats with this approach (which are documented in the code), but it's still substantially better than before.

2024-11-27Revert "Blind attempt to fix _configthreadlocale() failures on MinGW."Thomas Munro
This reverts commit 2cf91ccb73ce888c44e3751548fb7c77e87335f2. When using the old msvcrt.dll, MinGW would supply its own dummy version of _configthreadlocale() that just returns -1 if you try to use it. For a time we tolerated that to shut the build farm up. We would fall back to code that was enough for the tests to pass, but it would surely have risked crashing a real multithreaded program. We don't need that kludge anymore, because we can count on ucrt. We expect the real _configthreadlocale() to be present, and the ECPG tests will now fail if it isn't. The workaround was dead code and it's time to revert it. (A later patch still under review proposes to remove this use of _configthreadlocale() completely but we're unwinding this code in steps.)

2024-11-27Require ucrt if using MinGW.Thomas Munro
Historically we tolerated the absence of various C runtime library features for the benefit of the MinGW tool chain, because it used ancient msvcrt.dll for a long period of time. It now uses ucrt by default (like Windows 10+, Visual Studio 2015+), and that's the only configuration we're testing. In practice, we effectively required ucrt already in PostgreSQL 17, when commit 8d9a9f03 required _create_locale etc, first available in msvcr120.dll (Visual Studio 2013, the last of the pre-ucrt series of runtimes), and for MinGW users that practically meant ucrt because it was difficult or impossible to use msvcr120.dll. That may even not have been the first such case, but old MinGW configurations had already dropped off our testing radar so we weren't paying much attention. This commit formalizes the requirement. It also removes a couple of obsolete comments that discussed msvcrt.dll limitations, and some tests of !defined(_MSC_VER) to imply msvcrt.dll. There are many more anachronisms, but it'll take some time to figure out how to remove them all. APIs affected relate to locales, UTF-8, threads, large files and more. Thanks to Peter Eisentraut for the documentation change. It's not really necessary to talk about ucrt explicitly in such a short section, since it's the default for MinGW-w64 and MSYS2. It's enough to prune references and broken links to much older tools.

All modern Windows systems have _configthreadlocale(). It was first introduced in msvcr80.dll from Visual Studio 2005. Historically, MinGW was stuck on even older msvcrt.dll, but added its own dummy implementation of the function when using msvcrt.dll years ago anyway, effectively rendering the configure test useless. In practice we don't encounter the dummy anymore because modern MinGW uses ucrt.

2024-11-27Support LIKE with nondeterministic collationsPeter Eisentraut
This allows for example using LIKE with case-insensitive collations. There was previously no internal implementation of this, so it was met with a not-supported error. This adds the internal implementation and removes the error. The implementation follows the specification of the SQL standard for this. Unlike with deterministic collations, the LIKE matching cannot go character by character but has to go substring by substring. For example, if we are matching against LIKE 'foo%bar', we can't start by looking for an 'f', then an 'o', but instead with have to find something that matches 'foo'. This is because the collation could consider substrings of different lengths to be equal. This is all internal to MatchText() in like_match.c. The changes in GenericMatchText() in like.c just pass through the locale information to MatchText(), which was previously not needed. This matches exactly Generic_Text_IC_like() below. ILIKE is not affected. (It's unclear whether ILIKE makes sense under nondeterministic collations.) This also updates match_pattern_prefix() in like_support.c to support optimizing the case of an exact pattern with nondeterministic collations. This was already alluded to in the previous code.

2024-11-27Handle better implicit transaction state of pipeline modeMichael Paquier
When using a pipeline, a transaction starts from the first command and is committed with a Sync message or when the pipeline ends. Functions like IsInTransactionBlock() or PreventInTransactionBlock() were already able to understand a pipeline as being in a transaction block, but it was not the case of CheckTransactionBlock(). This function is called for example to generate a WARNING for SET LOCAL, complaining that it is used outside of a transaction block. The current state of the code caused multiple problems, like: - SET LOCAL executed at any stage of a pipeline issued a WARNING, even if the command was at least second in line where the pipeline is in a transaction state. - LOCK TABLE failed when invoked at any step of a pipeline, even if it should be able to work within a transaction block. The pipeline protocol assumes that the first command of a pipeline is not part of a transaction block, and that any follow-up commands is considered as within a transaction block. This commit changes the backend so as an implicit transaction block is started each time the first Execute message of a pipeline has finished processing, with this implicit transaction block ended once a sync is processed. The checks based on XACT_FLAGS_PIPELINING in the routines checking if we are in a transaction block are not necessary: it is enough to rely on the existing ones. Some tests are added to pgbench, that can be backpatched down to v17 when \syncpipeline is involved and down to v14 where \startpipeline and \endpipeline are available. This is unfortunately limited regarding the error patterns that can be checked, but it provides coverage for various pipeline combinations to check if these succeed or fail. These tests are able to capture the case of SET LOCAL's WARNING. The author has proposed a different feature to improve the coverage by adding similar meta-commands to psql where error messages could be checked, something more useful for the cases where commands cannot be used in transaction blocks, like REINDEX CONCURRENTLY or VACUUM. This is considered as future work for v18~.

2024-11-26Reordering DISTINCT keys to match input path's pathkeysRichard Guo
The ordering of DISTINCT items is semantically insignificant, so we can reorder them as needed. In fact, in the parser, we absorb the sorting semantics of the sortClause as much as possible into the distinctClause, ensuring that one clause is a prefix of the other. This can help avoid a possible need to re-sort. In this commit, we attempt to adjust the DISTINCT keys to match the input path's pathkeys. This can likewise help avoid re-sorting, or allow us to use incremental-sort to save efforts. For DISTINCT ON expressions, the parser already ensures that they match the initial ORDER BY expressions. When reordering the DISTINCT keys, we must ensure that the resulting pathkey list matches the initial distinctClause pathkeys. This introduces a new GUC, enable_distinct_reordering, which allows the optimization to be disabled if needed.

2024-11-25Fix NULLIF()'s handling of read-write expanded objects.Tom Lane
If passed a read-write expanded object pointer, the EEOP_NULLIF code would hand that same pointer to the equality function and then (unless equality was reported) also return the same pointer as its value. This is no good, because a function that receives a read-write expanded object pointer is fully entitled to scribble on or even delete the object, thus corrupting the NULLIF output. (This problem is likely unobservable with the equality functions provided in core Postgres, but it's easy to demonstrate with one coded in plpgsql.) To fix, make sure the pointer passed to the equality function is read-only. We can still return the original read-write pointer as the NULLIF result, allowing optimization of later operations. Per bug #18722 from Alexander Lakhin. This has been wrong since we invented expanded objects, so back-patch to all supported branches.

2024-11-25Update configure probes for CFLAGS needed for ARM CRC instructions.Tom Lane
On ARM platforms where the baseline CPU target lacks CRC instructions, we need to supply a -march flag to persuade the compiler to compile such instructions. It turns out that our existing choice of "-march=armv8-a+crc" has not worked for some time, because recent gcc will interpret that as selecting software floating point, and then will spit up if the platform requires hard-float ABI, as most do nowadays. The end result was to silently fall back to software CRC, which isn't very desirable since in practice almost all currently produced ARM chips do have hardware CRC. We can fix this by using "-march=armv8-a+crc+simd" to enable the correct ABI choice. (This has no impact on the code actually generated, since neither of the files we compile with this flag does any floating-point stuff, let alone SIMD.) Keep the test for "-march=armv8-a+crc" since that's required for soft-float ABI, but try that second since most platforms we're likely to build on use hard-float.

2024-11-25Assume that <stdbool.h> conforms to the C standard.Thomas Munro
Previously we checked "for <stdbool.h> that conforms to C99" using autoconf's AC_HEADER_STDBOOL macro. We've required C99 since PostgreSQL 12, so the test was redundant, and under C23 it was broken: autoconf 2.69's implementation doesn't understand C23's new empty header (the macros it's looking for went away, replaced by language keywords). Later autoconf versions fixed that, but let's just remove the anachronistic test. HAVE_STDBOOL_H and HAVE__BOOL will no longer be defined, but they weren't directly tested in core or likely extensions (except in 11, see below). PG_USE_STDBOOL (or USE_STDBOOL in 11 and 12) is still defined when sizeof(bool) is 1, which should be true on all modern systems. Otherwise we define our own bool type and values of size 1, which would fail to compile under C23 as revealed by the broken test. (We'll probably clean that dead code up in master, but here we want a minimal back-patchable change.) This came to our attention when GCC 15 recently started using using C23 by default and failed to compile the replacement code, as reported by Sam James and build farm animal alligator. Back-patch to all supported releases, and then two older versions that also know about <stdbool.h>, per the recently-out-of-support policy[1]. 12 requires C99 so it's much like the supported releases, but 11 only assumes C89 so it now uses AC_CHECK_HEADERS instead of the overly picky AC_HEADER_STDBOOL. (I could find no discussion of which historical systems had <stdbool.h> but failed the conformance test; if they ever existed, they surely aren't relevant to that policy's goals.)

Commit 7b88529f4363994450bd4cd3c172006a8a77e222 fixed a regression spanning these features, but it didn't test them. It did test code paths sufficient for their present implementations, so no back-patch. Reported by Matthew Woodcraft. Discussion: https://postgr.es/m/87iksnsbhx.fsf@golux.woodcraft.me.uk
2024-11-24Teach bitmap path generation about transforming OR-clauses to SAOP'sAlexander Korotkov
When optimizer generates bitmap paths, it considers breaking OR-clause arguments one-by-one. But now, a group of similar OR-clauses can be transformed into SAOP during index matching. So, bitmap paths should keep up. This commit teaches bitmap paths generation machinery to group similar OR-clauses into dedicated RestrictInfos. Those RestrictInfos are considered both to match index as a whole (as SAOP), or to match as a set of individual OR-clause argument one-by-one (the old way). Therefore, bitmap path generation will takes advantage of OR-clauses to SAOP's transformation. The old way of handling them is also considered. So, there shouldn't be planning regression.

2024-11-24Transform OR-clauses to SAOP's during index matchingAlexander Korotkov
This commit makes match_clause_to_indexcol() match "(indexkey op C1) OR (indexkey op C2) ... (indexkey op CN)" expression to the index while transforming it into "indexkey op ANY(ARRAY[C1, C2, ...])" (ScalarArrayOpExpr node). This transformation allows handling long OR-clauses with single IndexScan avoiding diving them into a slower BitmapOr. We currently restrict Ci to be either Const or Param to apply this transformation only when it's clearly beneficial. However, in the future, we might switch to a liberal understanding of constants, as it is in other cases.

2024-11-22Add INT64_HEX_FORMAT and UINT64_HEX_FORMAT to c.h.Nathan Bossart
Like INT64_FORMAT and UINT64_FORMAT, these macros produce format strings for 64-bit integers. However, INT64_HEX_FORMAT and UINT64_HEX_FORMAT generate the output in hexadecimal instead of decimal. Besides introducing these macros, this commit makes use of them in several places. This was originally intended to be part of commit 5d6187d2a2, but I left it out because I felt there was a nonzero chance that back-patching these new macros into c.h could cause problems with third-party code. We tend to be less cautious with such changes in new major versions. Note that UINT64_HEX_FORMAT was originally added in commit ee1b30f128, but it was placed in test_radixtree.c, so it wasn't widely available. This commit moves UINT64_HEX_FORMAT to c.h.
