* pgindent run for 9.4Bruce Momjian2014-05-062-10/+10
| | | | | This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.
* Update copyright for 2014Bruce Momjian2014-01-073-3/+3
| | | | | Update all files in head, and files COPYRIGHT and legal.sgml in all back branches.
* Use improved vsnprintf calling logic in more places.Tom Lane2013-10-241-4/+5
| | | | | | | | | | | | | | | | | | | | | | When we are using a C99-compliant vsnprintf implementation (which should be most places, these days) it is worth the trouble to make use of its report of how large the buffer needs to be to succeed. This patch adjusts stringinfo.c and some miscellaneous usages in pg_dump to do that, relying on the logic recently added in libpgcommon's psprintf.c. Since these places want to know the number of bytes written once we succeed, modify the API of pvsnprintf() to report that. There remains near-duplicate logic in pqexpbuffer.c, but since that code is in libpq, psprintf.c's approach of exit()-on-error isn't appropriate for use there. Also note that I didn't bother touching the multitude of places that call (v)snprintf without any attempt to provide a resizable buffer. Release-note-worthy incompatibility: the API of appendStringInfoVA() changed. If there's any third-party code that's calling that directly, it will need tweaking along the same lines as in this patch. David Rowley and Tom Lane
* Reset the binary heap in MergeAppend rescans.Tom Lane2013-08-301-0/+1
| | | | | | | | Failing to do so can cause queries to return wrong data, error out or crash. This requires adding a new binaryheap_reset() method to binaryheap.c, but that probably should have been there anyway. Per bug #8410 from Terje Elde. Diagnosis and patch by Andres Freund.
* Improve ilist.h's support for deletion of slist elements during iteration.Tom Lane2013-07-241-11/+51
| | | | | | | | | | | | | | | | | | Previously one had to use slist_delete(), implying an additional scan of the list, making this infrastructure considerably less efficient than traditional Lists when deletion of element(s) in a long list is needed. Modify the slist_foreach_modify() macro to support deleting the current element in O(1) time, by keeping a "prev" pointer in addition to "cur" and "next". Although this makes iteration with this macro a bit slower, no real harm is done, since in any scenario where you're not going to delete the current list element you might as well just use slist_foreach instead. Improve the comments about when to use each macro. Back-patch to 9.3 so that we'll have consistent semantics in all branches that provide ilist.h. Note this is an ABI break for callers of slist_foreach_modify(). Andres Freund and Tom Lane
* pgindent run for release 9.3Bruce Momjian2013-05-291-3/+3

* Basic binary heap implementation.Robert Haas2012-11-291-0/+53
| | | | | | | | | | There are probably other places where this can be used, but for now, this just makes MergeAppend use it, so that this code will have test coverage. There is other work in the queue that will use this, as well. Abhijit Menon-Sen, reviewed by Andres Freund, Robert Haas, Álvaro Herrera, Tom Lane, and others.
* Add explicit casts in ilist.h's inline functions.Tom Lane2012-11-271-3/+3
| | | | | | Needed to silence C++ errors, per report from Peter Eisentraut. Andres Freund
* Remove unnecessary "head" arguments from some dlist/slist functions.Tom Lane2012-10-181-33/+12
| | | | | | | | dlist_delete, dlist_insert_after, dlist_insert_before, slist_insert_after do not need access to the list header, and indeed insisting on that negates one of the main advantages of a doubly-linked list. In consequence, revert addition of "cache_bucket" field to CatCTup.
* Code review for inline-list patch.Tom Lane2012-10-181-212/+201
| | | | | | | Make foreach macros less syntactically dangerous, and fix some typos in evidently-never-tested ones. Add missing slist_next_node and slist_head_node functions. Fix broken dlist_check code. Assorted comment improvements.
* Embedded list interfaceAlvaro Herrera2012-10-172-85/+767
| | | | | | | | | | | | | | | | | | | Provide a common implementation of embedded singly-linked and doubly-linked lists. "Embedded" in the sense that the nodes' next/previous pointers exist within some larger struct; this design choice reduces memory allocation overhead. Most of the implementation uses inlineable functions (where supported), for performance. Some existing uses of both types of lists have been converted to the new code, for demonstration purposes. Other uses can (and probably will) be converted in the future. Since dllist.c is unused after this conversion, it has been removed.

* Add missing format attributesPeter Eisentraut2011-09-101-1/+2
| | | | | | | | | | | Add __attribute__ decorations for printf format checking to the places that were missing them. Fix the resulting warnings. Add -Wmissing-format-attribute to the standard set of warnings for GCC, so these don't happen again. The warning fixes here are relatively harmless. The one serious problem discovered by this was already committed earlier in cf15fb5cabfbc71e07be23cfbc813daee6c5014f.

* Assorted minor refactoring in EXPLAIN.Tom Lane2009-07-241-1/+7
| | | | | | | | | | This is believed to not change the output at all, with one known exception: "Subquery Scan foo" becomes "Subquery Scan on foo". (We can fix that if anyone complains, but it would be a wart, because the old code was clearly inconsistent.) The main intention is to remove duplicate coding and provide a cleaner base for subsequent EXPLAIN patching. Robert Haas

| | | | | | | | | | | | | for details). It doesn't really do that much yet, since there are no short-term memory contexts in the executor, but the infrastructure is in place and long-term contexts are handled reasonably. A few long- standing bugs have been fixed, such as 'VACUUM; anything' in a single query string crashing. Also, out-of-memory is now considered a recoverable ERROR, not FATAL. Eliminate a large amount of crufty, now-dead code in and around memory management. Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and backend startup.

| | | | | | | | | | | | | | | | | | | | | | | syscache and relcache flushes). Relcache entry rebuild now preserves original tupledesc, rewrite rules, and triggers if possible, so that pointers to these things remain valid --- if these things change while relcache entry has positive refcount, we elog(ERROR) to avoid later crash. Arrange for xact-local rels to be rebuilt when an SI inval message is seen for them, so that they are updated by CommandCounterIncrement the same as regular rels. (This is useful because of Hiroshi's recent changes to process our own SI messages at CommandCounterIncrement time.) This allows simplification of some routines that previously hacked around the lack of an automatic update. catcache now keeps its own copy of tupledesc for its relation, rather than depending on the relcache's copy; this avoids needing to reinitialize catcache during a cache flush, which saves some cycles and eliminates nasty circularity problems that occur if a cache flush happens while trying to initialize a catcache. Eliminate a number of permanent memory leaks that used to happen during catcache or relcache flush; not least of which was that catcache never freed any cached tuples! (Rule parsetree storage is still leaked, however; will fix that separately.) Nothing done yet about code that uses tuples retrieved by SearchSysCache for longer than is safe.
