Tom Lane	f10f0ae420	Replace RelationOpenSmgr() with RelationGetSmgr(). ... The idea behind this patch is to design out bugs like the one fixed by commit 9d523119f. Previously, once one did RelationOpenSmgr(rel), it was considered okay to access rel->rd_smgr directly for some not-very-clear interval. But since that pointer will be cleared by relcache flushes, we had bugs arising from overreliance on a previous RelationOpenSmgr call still being effective. Now, very little code except that in rel.h and relcache.c should ever touch the rd_smgr field directly. The normal coding rule is to use RelationGetSmgr(rel) and not expect the result to be valid for longer than one smgr function call. There are a couple of places where using the function every single time seemed like overkill, but they are now annotated with large warning comments. Amul Sul, after an idea of mine.

Tom Lane	44cac93464	Avoid using potentially-under-aligned page buffers. ... There's a project policy against using plain "char buf[BLCKSZ]" local or static variables as page buffers; preferred style is to palloc or malloc each buffer to ensure it is MAXALIGN'd. However, that policy's been ignored in an increasing number of places. We've apparently got away with it so far, probably because (a) relatively few people use platforms on which misalignment causes core dumps and/or (b) the variables chance to be sufficiently aligned anyway. But this is not something to rely on. Moreover, even if we don't get a core dump, we might be paying a lot of cycles for misaligned accesses. To fix, invent new union types PGAlignedBlock and PGAlignedXLogBlock that the compiler must allocate with sufficient alignment, and use those in place of plain char arrays. I used these types even for variables where there's no risk of a misaligned access, since ensuring proper alignment should make kernel data transfers faster. I also changed some places where we had been palloc'ing short-lived buffers, for coding style uniformity and to save palloc/pfree overhead. Since this seems to be a live portability hazard (despite the lack of field reports), back-patch to all supported versions. Patch by me; thanks to Michael Paquier for review.

Tom Lane	af1a949109	Further cleanup of client dependencies on src/include/catalog headers. ... In commit 9c0a0de4c, I'd failed to notice that catalog/catalog.h should also be considered a frontend-unsafe header, because it includes (and needs) the full form of pg_class.h, not to mention relcache.h. However, various frontend code was depending on it to get TABLESPACE_VERSION_DIRECTORY, so refactoring of some sort is called for. The cleanest answer seems to be to move TABLESPACE_VERSION_DIRECTORY, as well as the OIDCHARS symbol, to common/relpath.h. Do that, and mop up inclusions as necessary. (I found that quite a few current users of catalog/catalog.h don't seem to need it at all anymore, apparently as a result of the refactorings that created common/relpath.[hc]. And initdb.c needed it only as a route to pg_class_d.h.) Discussion: https://postgr.es/m/6629.1523294509@sss.pgh.pa.us	8 years ago
Peter Eisentraut	8b9e9644dc	Replace AclObjectKind with ObjectType ... AclObjectKind was basically just another enumeration for object types, and we already have a preferred one for that. It's only used in aclcheck_error. By using ObjectType instead, we can also give some more precise error messages, for example "index" instead of "relation".

Tom Lane	382ceffdf7	Phase 3 of pgindent updates. ... 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.

Noah Misch	3a0d473192	Use wrappers of PG_DETOAST_DATUM_PACKED() more. ... This makes almost all core code follow the policy introduced in the previous commit. Specific decisions: - Text search support functions with char* and length arguments, such as prsstart and lexize, may receive unaligned strings. I doubt maintainers of non-core text search code will notice. - Use plain VARDATA() on values detoasted or synthesized earlier in the same function. Use VARDATA_ANY() on varlenas sourced outside the function, even if they happen to always have four-byte headers. As an exception, retain the universal practice of using VARDATA() on return values of SendFunctionCall(). - Retain PG_GETARG_BYTEA_P() in pageinspect. (Page images are too large for a one-byte header, so this misses no optimization.) Sites that do not call get_page_from_raw() typically need the four-byte alignment. - For now, do not change btree_gist. Its use of four-byte headers in memory is partly entangled with storage of 4-byte headers inside GBT_VARKEY, on disk. - For now, do not change gtrgm_consistent() or gtrgm_distance(). They incorporate the varlena header into a cache, and there are multiple credible implementation strategies to consider.	9 years ago

Peter Eisentraut	e7128e8dbb	Create function prototype as part of PG_FUNCTION_INFO_V1 macro ... Because of gcc -Wmissing-prototypes, all functions in dynamically loadable modules must have a separate prototype declaration. This is meant to detect global functions that are not declared in header files, but in cases where the function is called via dfmgr, this is redundant. Besides filling up space with boilerplate, this is a frequent source of compiler warnings in extension modules. We can fix that by creating the function prototype as part of the PG_FUNCTION_INFO_V1 macro, which such modules have to use anyway. That makes the code of modules cleaner, because there is one less place where the entry points have to be listed, and creates an additional check that functions have the right prototype. Remove now redundant prototypes from contrib and other modules.	12 years ago
