* Fix CVE-2013-0255 properly.Tom Lane2013-02-13
| | | | | | | | | | | | Revert commit ab0f7b6089fd215f6ce6081e2e222c38d643a526 (in HEAD only) in favor of the proper solution, which is to declare enum_recv() correctly in the system catalogs. It should be declared to take type "internal" not "cstring". Also improve the type_sanity regression test, which should have caught this typo, so that it actually would. Most of the relevant checks on the signature of type I/O functions should not have been restricted to basetypes/pseudotypes, as they should apply to any type's I/O functions.
* Prevent execution of enum_recv() from SQL.Tom Lane2013-02-04
| | | | | | | | | | | | | | | | | This function was misdeclared to take cstring when it should take internal. This at least allows crashing the server, and in principle an attacker might be able to use the function to examine the contents of server memory. The correct fix is to adjust the system catalog contents (and fix the regression tests that should have caught this but failed to). However, asking users to correct the catalog contents in existing installations is a pain, so as a band-aid fix for the back branches, install a check in enum_recv() to make it throw error if called with a cstring argument. We will later revert this in HEAD in favor of correcting the catalogs. Our thanks to Sumit Soni (via Secunia SVCRP) for reporting this issue. Security: CVE-2013-0255

* 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.

* Clean up the #include mess a little.Tom Lane2011-09-04
| | | | | | | | | | | | | | | | | walsender.h should depend on xlog.h, not vice versa. (Actually, the inclusion was circular until a couple hours ago, which was even sillier; but Bruce broke it in the expedient rather than logically correct direction.) Because of that poor decision, plus blind application of pgrminclude, we had a situation where half the system was depending on xlog.h to include such unrelated stuff as array.h and guc.h. Clean up the header inclusion, and manually revert a lot of what pgrminclude had done so things build again. This episode reinforces my feeling that pgrminclude should not be run without adult supervision. Inclusion changes in header files in particular need to be reviewed with great care. More generally, it'd be good if we had a clearer notion of module layering to dictate which headers can sanely include which others ... but that's a big task for another day.

* Wrap calls to SearchSysCache and related functions using macros.Robert Haas2010-02-14
| | | | | | | | | | | | The purpose of this change is to eliminate the need for every caller of SearchSysCache, SearchSysCacheCopy, SearchSysCacheExists, GetSysCacheOid, and SearchSysCacheList to know the maximum number of allowable keys for a syscache entry (currently 4). 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.

* Provide for binary input/output of enums, to fix complaint from Merlin Moncure.Andrew Dunstan2007-09-04
| | | | | This just provides text values, we're not exposing the underlying Oid representation. Catalog version bumped.
* Downgrade implicit casts to text to be assignment-only, except for the onesTom Lane2007-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | from the other string-category types; this eliminates a lot of surprising interpretations that the parser could formerly make when there was no directly applicable operator. Create a general mechanism that supports casts to and from the standard string types (text,varchar,bpchar) for *every* datatype, by invoking the datatype's I/O functions. These new casts are assignment-only in the to-string direction, explicit-only in the other, and therefore should create no surprising behavior. Remove a bunch of thereby-obsoleted datatype-specific casting functions. The "general mechanism" is a new expression node type CoerceViaIO that can actually convert between *any* two datatypes if their external text representations are compatible. This is more general than needed for the immediate feature, but might be useful in plpgsql or other places in future. This commit does nothing about the issue that applying the concatenation operator || to non-text types will now fail, often with strange error messages due to misinterpreting the operator as array concatenation. Since it often (not always) worked before, we should either make it succeed or at least give a more user-friendly error; but details are still under debate. Peter Eisentraut and Tom Lane
