* Remove unused #include's from backend .c filesPeter Eisentraut2024-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | as determined by include-what-you-use (IWYU) While IWYU also suggests to *add* a bunch of #include's (which is its main purpose), this patch does not do that. In some cases, a more specific #include replaces another less specific one. Some manual adjustments of the automatic result: - IWYU currently doesn't know about includes that provide global variable declarations (like -Wmissing-variable-declarations), so those includes are being kept manually. - All includes for port(ability) headers are being kept for now, to play it safe. - No changes of catalog/pg_foo.h to catalog/pg_foo_d.h, to keep the patch from exploding in size. Note that this patch touches just *.c files, so nothing declared in header files changes in hidden ways. As a small example, in src/backend/access/transam/rmgr.c, some IWYU pragma annotations are added to handle a special case there.

* Refactor aclcheck functionsPeter Eisentraut2022-11-13
| | | | | | | | | | | | | | | | | | Instead of dozens of mostly-duplicate pg_foo_aclcheck() functions, write one common function object_aclcheck() that can handle almost all of them. We already have all the information we need, such as which system catalog corresponds to which catalog table and which column is the ACL column. There are a few pg_foo_aclcheck() that don't work via the generic function and have special APIs, so those stay as is. I also changed most pg_foo_aclmask() functions to static functions, since they are not used outside of aclchk.c.

* Add 'noError' argument to encoding conversion functions.Heikki Linnakangas2021-04-01
| | | | | | | | | | | | | | | | | | | | | | With the 'noError' argument, you can try to convert a buffer without knowing the character boundaries beforehand. The functions now need to return the number of input bytes successfully converted. This is is a backwards-incompatible change, if you have created a custom encoding conversion with CREATE CONVERSION. This adds a check to pg_upgrade for that, refusing the upgrade if there are any user-defined encoding conversions. Custom conversions are very rare, there are no commonly used extensions that I know of that uses that feature. No other objects can depend on conversions, so if you do have one, you can fairly easily drop it before upgrading, and recreate it after the upgrade with an updated version. Add regression tests for built-in encoding conversions. This doesn't cover every conversion, but it covers all the internal functions in conv.c that are used to implement the conversions.

* Remove utils/acl.h from catalog/objectaddress.hPeter Eisentraut2020-03-10
| | | | | | | | | | | | | | | | | | The need for this was removed by 8b9e9644dc6a9bd4b7a97950e6212f63880cf18b. A number of files now need to include utils/acl.h or parser/parse_node.h explicitly where they previously got it indirectly somehow. Since parser/parse_node.h already includes nodes/parsenodes.h, the latter is then removed where the former was added. Also, remove nodes/pg_list.h from objectaddress.h, since that's included via nodes/parsenodes.h.

* Remove dead encoding-conversion functions.Tom Lane2019-07-05
| | | | | | | | | | | | | | | | | | | | | The code for conversions SQL_ASCII <-> MULE_INTERNAL and SQL_ASCII <-> UTF8 was unreachable, because we long ago changed the wrapper functions pg_do_encoding_conversion() et al so that they have hard-wired behaviors for conversions involving SQL_ASCII. (At least some of those fast paths date back to 2002, though it looks like we may not have been totally consistent about this until later.) Given the lack of complaints, nobody is dissatisfied with this state of affairs. Hence, let's just remove the unreachable code. Also, change CREATE CONVERSION so that it rejects attempts to define such conversions. Since we consider that SQL_ASCII represents lack of knowledge about the encoding in use, such a conversion would be semantically dubious even if it were reachable. Adjust a couple of regression test cases that had randomly decided to rely on these conversion functions rather than any other ones. Discussion: https://postgr.es/m/41163.1559156593@sss.pgh.pa.us

* Merge catalog/pg_foo_fn.h headers back into pg_foo.h headers.Tom Lane2018-04-08
| | | | | | | | | | | | | Traditionally, include/catalog/pg_foo.h contains extern declarations for functions in backend/catalog/pg_foo.c, in addition to its function as the authoritative definition of the pg_foo catalog's rowtype. In some cases, we'd been forced to split out those extern declarations into separate pg_foo_fn.h headers so that the catalog definitions could be #include'd by frontend code. That problem is gone as of commit 9c0a0de4c, so let's undo the splits to make things less confusing. Discussion: https://postgr.es/m/23690.1523031777@sss.pgh.pa.us
* Replace AclObjectKind with ObjectTypePeter Eisentraut2018-01-19
| | | | | | | | | 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". Reviewed-by: Michael Paquier <michael.paquier@gmail.com>

* Type names should not be quotedAlvaro Herrera2016-04-01
| | | | | | | | | Our actual convention, contrary to what I said in 59a2111b23f, is not to quote type names, as evidenced by unquoted use of format_type_be() result value in error messages. Remove quotes from recently tweaked messages accordingly. Per note from Tom Lane
* Improve internationalization of messages involving type namesAlvaro Herrera2016-03-28
| | | | | | | | | | | | | | | Change the slightly different variations of the message function FOO must return type BAR to a single wording, removing the variability in type name so that they all create a single translation entry; since the type name is not to be translated, there's no point in it being part of the message anyway. Also, change them all to use the same quoting convention, namely that the function name is not to be quoted but the type name is. (I'm not quite sure why this is so, but it's the clear majority.) Some similar messages such as "encoding conversion function FOO must ..." are also changed.

* Change many routines to return ObjectAddress rather than OIDAlvaro Herrera2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changed routines are mostly those that can be directly called by ProcessUtilitySlow; the intention is to make the affected object information more precise, in support for future event trigger changes. Originally it was envisioned that the OID of the affected object would be enough, and in most cases that is correct, but upon actually implementing the event trigger changes it turned out that ObjectAddress is more widely useful. Additionally, some command execution routines grew an output argument that's an object address which provides further info about the executed command. To wit: * for ALTER DOMAIN / ADD CONSTRAINT, it corresponds to the address of the new constraint * for ALTER OBJECT / SET SCHEMA, it corresponds to the address of the schema that originally contained the object. * for ALTER EXTENSION {ADD, DROP} OBJECT, it corresponds to the address of the object added to or dropped from the extension. There's no user-visible change in this commit, and no functional change either. Discussion: 20150218213255.GC6717@tamriel.snowman.net Reviewed-By: Stephen Frost, Andres Freund

* Make various variables const (read-only).Tom Lane2014-01-18
| | | | | | | | | | | | | | | | | | These changes should generally improve correctness/maintainability. A nice side benefit is that several kilobytes move from initialized data to text segment, allowing them to be shared across processes and probably reducing copy-on-write overhead while forking a new backend. Unfortunately this doesn't seem to help libpq in the same way (at least not when it's compiled with -fpic on x86_64), but we can hope the linker at least collects all nominally-const data together even if it's not actually part of the text segment. Also, make pg_encname_tbl[] static in encnames.c, since there seems no very good reason for any other code to use it; per a suggestion from Wim Lewis, who independently submitted a patch that was mostly a subset of this one.

* Split tuple struct defs from htup.h to htup_details.hAlvaro Herrera2012-08-30
| | | | | | | | | | | | This reduces unnecessary exposure of other headers through htup.h, which is very widely included by many files. I have chosen to move the function prototypes to the new file as well, because that means htup.h no longer needs to include tupdesc.h. In itself this doesn't have much effect in indirect inclusion of tupdesc.h throughout the tree, because it's also required by execnodes.h; but it's something to explore in the future, and it seemed best to do the htup.h change now while I'm busy with it.

This will make it far easier to increase the maximum number of keys in a future release should we choose to do so, and it makes the code shorter, too. Design and review by Tom Lane.
