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.

2017-06-21Phase 2 of pgindent updates.Tom Lane
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.

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.

2017-03-12Use wrappers of PG_DETOAST_DATUM_PACKED() more.Noah Misch
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.

2017-01-17Generate fmgr prototypes automaticallyPeter Eisentraut
Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains prototypes for all functions registered in pg_proc.h. This avoids having to manually maintain these prototypes across a random variety of header files. It also automatically enforces a correct function signature, and since there are warnings about missing prototypes, it will detect functions that are defined but not registered in pg_proc.h (or otherwise used).

2016-11-08Replace uses of SPI_modifytuple that intend to allocate in current context.Tom Lane
Invent a new function heap_modify_tuple_by_cols() that is functionally equivalent to SPI_modifytuple except that it always allocates its result by simple palloc. I chose however to make the API details a bit more like heap_modify_tuple: pass a tupdesc rather than a Relation, and use bool convention for the isnull array. Use this function in place of SPI_modifytuple at all call sites where the intended behavior is to allocate in current context. (There actually are only two call sites left that depend on the old behavior, which makes me wonder if we should just drop this function rather than keep it.) This new function is easier to use than heap_modify_tuple() for purposes of replacing a single column (or, really, any fixed number of columns). There are a number of places where it would simplify the code to change over, but I resisted that temptation for the moment ... everywhere except in plpgsql's exec_assign_value(); changing that might offer some small performance benefit, so I did it. This is on the way to removing SPI_push/SPI_pop, but it seems like good code cleanup in its own right. Discussion: <9633.1478552022@sss.pgh.pa.us>
2016-11-08Make SPI_fnumber() reject dropped columns.Tom Lane
There's basically no scenario where it's sensible for this to match dropped columns, so put a test for dropped-ness into SPI_fnumber() itself, and excise the test from the small number of callers that were paying attention to the case. (Most weren't :-(.) In passing, normalize tests at call sites: always reject attnum <= 0 if we're disallowing system columns. Previously there was a mixture of "< 0" and "<= 0" tests. This makes no practical difference since SPI_fnumber() never returns 0, but I'm feeling pedantic today. Also, in the places that are actually live user-facing code and not legacy cruft, distinguish "column not found" from "can't handle system column". Per discussion with Jim Nasby; thi supersedes his original patch that just changed the behavior at one call site. Discussion: <b2de8258-c4c0-1cb8-7b97-e8538e5c975c@BlueTreble.com>
2016-03-12Widen query numbers-of-tuples-processed counters to uint64.Tom Lane
This patch widens SPI_processed, EState's es_processed field, PortalData's portalPos field, FuncCallContext's call_cntr and max_calls fields, ExecutorRun's count argument, PortalRunFetch's result, and the max number of rows in a SPITupleTable to uint64, and deals with (I hope) all the ensuing fallout. Some of these values were declared uint32 before, and others "long". I also removed PortalData's posOverflow field, since that logic seems pretty useless given that portalPos is now always 64 bits. The user-visible results are that command tags for SELECT etc will correctly report tuple counts larger than 4G, as will plpgsql's GET GET DIAGNOSTICS ... ROW_COUNT command. Queries processing more tuples than that are still not exactly the norm, but they're becoming more common. Most values associated with FETCH/MOVE distances, such as PortalRun's count argument and the count argument of most SPI functions that have one, remain declared as "long". It's not clear whether it would be worth promoting those to int64; but it would definitely be a large dollop of additional API churn on top of this, and it would only help 32-bit platforms which seem relatively less likely to see any benefit.

2015-05-20Collection of typo fixes.Heikki Linnakangas
Use "a" and "an" correctly, mostly in comments. Two error messages were also fixed (they were just elogs, so no translation work required). Two function comments in pg_proc.h were also fixed. Etsuro Fujita reported one of these, but I found a lot more with grep. Also fix a few other typos spotted while grepping for the a/an typos. For example, "consists out of ..." -> "consists of ...". Plus a "though"/ "through" mixup reported by Euler Taveira. Many of these typos were in old code, which would be nice to backpatch to make future backpatching easier. But much of the code was new, and I didn't feel like crafting separate patches for each branch. So no backpatching.
2015-05-09Add new OID alias type regroleAndrew Dunstan
The new type has the scope of whole the database cluster so it doesn't behave the same as the existing OID alias types which have database scope, concerning object dependency. To avoid confusion constants of the new type are prohibited from appearing where dependencies are made involving it. Also, add a note to the docs about possible MVCC violation and optimization issues, which are general over the all reg* types. Kyotaro Horiguchi

2014-04-18Create function prototype as part of PG_FUNCTION_INFO_V1 macroPeter Eisentraut
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.

2011-10-12Throw a useful error message if an extension script file is fed to psql.Tom Lane
We have seen one too many reports of people trying to use 9.1 extension files in the old-fashioned way of sourcing them in psql. Not only does that usually not work (due to failure to substitute for MODULE_PATHNAME and/or @extschema@), but if it did work they'd get a collection of loose objects not an extension. To prevent this, insert an \echo ... \quit line that prints a suitable error message into each extension script file, and teach commands/extension.c to ignore lines starting with \echo. That should not only prevent any adverse consequences of loading a script file the wrong way, but make it crystal clear to users that they need to do it differently now. Tom Lane, following an idea of Andrew Dunstan's. Back-patch into 9.1 ... there is not going to be much value in this if we wait till 9.2.
2011-09-16Redesign the plancache mechanism for more flexibility and efficiency.Tom Lane
Rewrite plancache.c so that a "cached plan" (which is rather a misnomer at this point) can support generation of custom, parameter-value-dependent plans, and can make an intelligent choice between using custom plans and the traditional generic-plan approach. The specific choice algorithm implemented here can probably be improved in future, but this commit is all about getting the mechanism in place, not the policy. In addition, restructure the API to greatly reduce the amount of extraneous data copying needed. The main compromise needed to make that possible was to split the initial creation of a CachedPlanSource into two steps. It's worth noting in particular that SPI_saveplan is now deprecated in favor of SPI_keepplan, which accomplishes the same end result with zero data copying, and no need to then spend even more cycles throwing away the original SPIPlan. The risk of long-term memory leaks while manipulating SPIPlans has also been greatly reduced. Most of this improvement is based on use of the recently-added MemoryContextSetParent primitive.
2011-09-09Move Timestamp/Interval typedefs and basic macros into datatype/timestamp.h.Tom Lane
As per my recent proposal, this refactors things so that these typedefs and macros are available in a header that can be included in frontend-ish code. I also changed various headers that were undesirably including utils/timestamp.h to include datatype/timestamp.h instead. Unsurprisingly, this showed that half the system was getting utils/timestamp.h by way of xlog.h. No actual code changes here, just header refactoring.

2011-02-14Avoid use of CREATE OR REPLACE FUNCTION in extension installation files.Tom Lane
It was never terribly consistent to use OR REPLACE (because of the lack of comparable functionality for data types, operators, etc), and experimentation shows that it's now positively pernicious in the extension world. We really want a failure to occur if there are any conflicts, else it's unclear what the extension-ownership state of the conflicted object ought to be. Most of the time, CREATE EXTENSION will fail anyway because of conflicts on other object types, but an extension defining only functions can succeed, with bad results.

2010-10-08Fix sloppy usage of TRIGGER_FIRED_BEFORE/TRIGGER_FIRED_AFTER.Tom Lane
Various places were testing TRIGGER_FIRED_BEFORE() where what they really meant was !TRIGGER_FIRED_AFTER(), or vice versa. This needs to be cleaned up because there are about to be more than two possible states. We might want to note this in the 9.1 release notes as something for trigger authors to double-check. For consistency's sake I also changed some places that assumed that TRIGGER_FIRED_FOR_ROW and TRIGGER_FIRED_FOR_STATEMENT are necessarily mutually exclusive; that's not in immediate danger of breaking, but it's still sloppier than it should be. Extracted from Dean Rasheed's patch for triggers on views. I'm committing this separately since it's an identifiable separate issue, and is the only reason for the patch to touch most of these particular files.

2008-03-25Simplify and standardize conversions between TEXT datums and ordinary CTom Lane
strings. This patch introduces four support functions cstring_to_text, cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and two macros CStringGetTextDatum and TextDatumGetCString. A number of existing macros that provided variants on these themes were removed. Most of the places that need to make such conversions now require just one function or macro call, in place of the multiple notational layers that used to be needed. There are no longer any direct calls of textout or textin, and we got most of the places that were using handmade conversions via memcpy (there may be a few still lurking, though). This commit doesn't make any serious effort to eliminate transient memory leaks caused by detoasting toasted text objects before they reach text_to_cstring. We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few places where it was easy, but much more could be done. Brendan Jurd and Tom Lane
