* Don't expose Windows' mbstowcs_l() and wcstombs_l().Thomas Munro2023-07-11
| | | | | | | | | | | | | | | | | | | | Windows has similar functions with leading underscores. Previously, we provided the rename via a macro in win32_port.h. In fact its functions are not always good replacements for the Unix functions, since they can't deal with UTF-8. They are only currently used by pg_locale.c, which is careful to redirect to other Windows routines for UTF-8. Given that portability hazard, it seem unlikely to be a good idea to encourage any other code to think of these functions as being available outside pg_locale.c. Any code that thinks it wants these functions probably wants our wchar2char() or char2wchar() routines instead, or it won't actually work on Windows in UTF-8 databases. Furthermore, some major libc implementations including glibc don't have them (they only have the standard variants without _l), so external code is very unlikely to require them to exist.

* All supported systems have locale_t.Thomas Munro2023-07-09
| | | | | | | | | | | | | | | | | | | | locale_t is defined by POSIX.1-2008 and SUSv4, and available on all targeted systems. For Windows, win32_port.h redirects to a partial implementation called _locale_t. We can now remove a lot of compile-time tests for HAVE_LOCALE_T, and associated comments and dead code branches that were needed for older computers. Since configure + MinGW builds didn't detect locale_t but now we assume that all systems have it, further inconsistencies among the 3 Windows build systems were revealed. With this commit, we no longer define HAVE_WCSTOMBS_L and HAVE_MBSTOWCS_L on any Windows build system, but we have logic to deal with that so that replacements are available where appropriate.

* ICU: do not convert locale 'C' to 'en-US-u-va-posix'.Jeff Davis2023-06-21
| | | | | | | | | | | | | | | | | | | | | Older versions of ICU canonicalize "C" to "en-US-u-va-posix"; but starting in ICU version 64, the "C" locale is considered obsolete. Postgres commit ea1db8ae70 introduced code to always canonicalize "C" to "en-US-u-va-posix" for consistency and convenience, but it was deemed too confusing. This commit removes that code, so that "C" is treated like other ICU locale names: canonicalization is attempted, and if it fails, the behavior is controlled by icu_validation_level. A similar change was previously committed as f7faa9976c, then reverted due to an ICU-version-dependent test failure. This commit un-reverts it, omitting the test because we now expect the behavior to depend on the version of ICU being used.

We've updated to pg_bsd_indent 2.1.2, which properly indents variable declarations that have multi-line initialization expressions (the continuation lines are now indented one tab stop). We've also updated to perltidy version 20230309 and changed some of its settings, which reduces its desire to add whitespace to lines to make assignments etc. line up. Going forward, that should make for fewer random-seeming changes to existing code. Discussion: https://postgr.es/m/20230428092545.qfb3y5wcu4cm75ur@alvherre.pgsql

* Canonicalize ICU locale names to language tags.Jeff Davis2023-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert to BCP47 language tags before storing in the catalog, except during binary upgrade or when the locale comes from an existing collation or template database. The resulting language tags can vary slightly between ICU versions. For instance, "@colBackwards=yes" is converted to "und-u-kb-true" in older versions of ICU, and to the simpler (but equivalent) "und-u-kb" in newer versions. The process of canonicalizing to a language tag also understands more input locale string formats than ucol_open(). For instance, "fr_CA.UTF-8" is misinterpreted by ucol_open() and the region is ignored; effectively treating it the same as the locale "fr" and opening the wrong collator. Canonicalization properly interprets the language and region, resulting in the language tag "fr-CA", which can then be understood by ucol_open(). This commit fixes a problem in prior versions due to ucol_open() misinterpreting locale strings as described above. For instance, creating an ICU collation with locale "fr_CA.UTF-8" would store that string directly in the catalog, which would later be passed to (and misinterpreted by) ucol_open(). After this commit, the locale string will be canonicalized to language tag "fr-CA" in the catalog, which will be properly understood by ucol_open(). Because this fix affects the resulting collator, we cannot change the locale string stored in the catalog for existing databases or collations; otherwise we'd risk corrupting indexes. Therefore, only canonicalize locales for newly-created (not upgraded) collations/databases. For similar reasons, do not backport.

Basic validation helps avoid minor mistakes and misspellings, which often fall back to the root locale instead of the intended locale. It's even more important to avoid such mistakes in ICU versions 54 and earlier, where the same (misspelled) locale string could fall back to different locales depending on the environment.

* Fix error inconsistency in older ICU versions.Jeff Davis2023-03-28
| | | | | | | | | | | | | | | | | | To support older ICU versions, we rely on icu_set_collation_attributes() to do error checking that is handled directly by ucol_open() in newer ICU versions. Commit 3b50275b12 introduced a slight inconsistency, where the error report includes the fixed-up locale string, rather than the locale string passed to pg_ucol_open(). Refactor slightly so that pg_ucol_open() handles the errors from both ucol_open() and icu_set_collation_attributes(), making it easier to see any differences between the error reports. It also makes pg_ucol_open() responsible for closing the UCollator on error, which seems like the right place.

* Handle the "und" locale in ICU versions 54 and older.Jeff Davis2023-03-23
| | | | | | | | | | | | | | | | | | | | | | The "und" locale is an alternative spelling of the root locale, but it was not recognized until ICU 55. To maintain common behavior across all supported ICU versions, check for "und" and replace with "root" before opening. Previously, the lack of support for "und" was dangerous, because versions 54 and older fall back to the environment when a locale is not found. If the user specified "und" for the language (which is expected and documented), it could not only resolve to the wrong collator, but it could unexpectedly change (which could lead to corrupt indexes). This effectively reverts commit d72900bded, which worked around the problem for the built-in "unicode" collation, and is no longer necessary.

* Split up guc.c for better build speed and ease of maintenance.Tom Lane2022-09-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | guc.c has grown to be one of our largest .c files, making it a bottleneck for compilation. It's also acquired a bunch of knowledge that'd be better kept elsewhere, because of our not very good habit of putting variable-specific check hooks here. Hence, split it up along these lines: * guc.c itself retains just the core GUC housekeeping mechanisms. * New file guc_funcs.c contains the SET/SHOW interfaces and some SQL-accessible functions for GUC manipulation. * New file guc_tables.c contains the data arrays that define the built-in GUC variables, along with some already-exported constant tables. * GUC check/assign/show hook functions are moved to the variable's home module, whenever that's clearly identifiable. A few hard- to-classify hooks ended up in commands/variable.c, which was already a home for miscellaneous GUC hook functions. To avoid cluttering a lot more header files with #include "guc.h", I also invented a new header file utils/guc_hooks.h and put all the GUC hook functions' declarations there, regardless of their originating module. That allowed removal of #include "guc.h" from some existing headers. The fallout from that (hopefully all caught here) demonstrates clearly why such inclusions are best minimized: there are a lot of files that, for example, were getting array.h at two or more levels of remove, despite not having any connection at all to GUCs in themselves. There is some very minor code beautification here, such as renaming a couple of inconsistently-named hook functions and improving some comments. But mostly this just moves code from point A to point B and deals with the ensuing needs for #include adjustments and exporting a few functions that previously weren't exported. Patch by me, per a suggestion from Andres Freund; thanks also to Michael Paquier for the idea to invent guc_funcs.c. Discussion: https://postgr.es/m/587607.1662836699@sss.pgh.pa.us

The previous minimal runtime version was either Windows Vista when building with at least Visual Studio 2015 or Windows XP for the rest. Windows 10 is the most modern version supported by Microsoft, and per discussion, as we don't have buildfarm members that run older versions anymore, this is the minimal supported version that suits better for our needs. This will actually make easier the development of some patches, two being async I/O and large page handling by avoiding a lot of compatibility gotchas, on platforms that have most likely few users anyway. It is possible to remove MIN_WINNT in win32.h and the macros IsWindowsXXXOrGreater() that were used in the code at runtime to check which version of Windows was getting used.

There wasn't ever a really good reason for them to be of type name; presumably this was just carried over from when they were fixed-size fields in pg_control, first into the corresponding pg_database fields, and then to pg_collation. The values are not identifiers or object names, and we don't ever look them up that way. Changing to type text saves space in the typical case, since locale names are typically only a few bytes long. But it is also possible that an ICU locale name with several customization options appended could be longer than 63 bytes, so this also enables that case, which was previously probably broken.

* Call pg_newlocale_from_collation() also with default collationPeter Eisentraut2022-01-20
| | | | | | | | | | | | | | | | Previously, callers of pg_newlocale_from_collation() did not call it if the collation was DEFAULT_COLLATION_OID and instead proceeded with a pg_locale_t of 0. Instead, now we call it anyway and have it return 0 if the default collation was passed. It already did this, so we just have to adjust the callers. This simplifies all the call sites and also makes future enhancements easier. After discussion and testing, the previous comment in pg_locale.c about avoiding this for performance reasons may have been mistaken since it was testing a very different patch version way back when.

* Initial pgindent and pgperltidy run for v14.Tom Lane2021-05-12
| | | | | | | | Also "make reformat-dat-files". The only change worthy of note is that pgindent messed up the formatting of launcher.c's struct LogicalRepWorkerId, which led me to notice that that struct wasn't used at all anymore, so I just took it out.

* Revert per-index collation version tracking feature.Thomas Munro2021-05-07
| | | | | | | | | | | | | | | | | | | | | | | Design problems were discovered in the handling of composite types and record types that would cause some relevant versions not to be recorded. Misgivings were also expressed about the use of the pg_depend catalog for this purpose. We're out of time for this release so we'll revert and try again. Commits reverted: 1bf946bd: Doc: Document known problem with Windows collation versions. cf002008: Remove no-longer-relevant test case. ef387bed: Fix bogus collation-version-recording logic. 0fb0a050: Hide internal error for pg_collation_actual_version(<bad OID>). ff942057: Suppress "warning: variable 'collcollate' set but not used". d50e3b1f: Fix assertion in collation version lookup. f24b1569: Rethink extraction of collation dependencies. 257836a7: Track collation versions for indexes. cd6f479e: Add pg_depend.refobjversion. 7d1297df: Remove pg_collation.collversion.
