* Portal and memory management infrastructure for extended query protocol.Tom Lane2003-05-02
| | | | | | | | | Both plannable queries and utility commands are now always executed within Portals, which have been revamped so that they can handle the load (they used to be good only for single SELECT queries). Restructure code to push command-completion-tag selection logic out of postgres.c, so that it won't have to be duplicated between simple and extended queries. initdb forced due to addition of a field to Query nodes.
* Code review for palloc0 patch --- avoid dangerous and unnecessaryTom Lane2002-12-16
| | | | | | | | practice of evaluating MemSet's arguments multiple times, except for the special case of newNode(), where we can assume the argument is a constant sizeof() operator. Also, add GetMemoryChunkContext() to mcxt.c's API, in preparation for fixing recent GEQO breakage.
* Tweak default memory context allocation policy so that a context is notTom Lane2002-12-15
| | | | | | | | | given any malloc block until something is first allocated in it; but thereafter, MemoryContextReset won't release that first malloc block. This preserves the quick-reset property of the original policy, without forcing 8K to be allocated to every context whether any of it is ever used or not. Also, remove some more no-longer-needed explicit freeing during ExecEndPlan.

* Change memory-space accounting mechanism in tuplesort.c and tuplestore.cTom Lane2002-08-12
| | | | | | | | to make a reasonable attempt at accounting for palloc overhead, not just the requested size of each memory chunk. Since in many scenarios this will make for a significant reduction in the amount of space acquired, partially compensate by doubling the default value of SORT_MEM to 1Mb. Per discussion in pgsql-general around 9-Jun-2002..

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in-chunk leaks, overwrite-next-chunk leaks and overwrite block-freeptr leaks. A in-chunk leak --- if something overwrite space after wanted (via palloc() size, but it is still inside chunk. For example x = palloc(12); /* create 16b chunk */ memset(x, '#', 13); this leak is in the current source total invisible, because chunk is 16b and leak is in the "align space". For this feature I add data_size to StandardChunk, and all memory which go from AllocSetAlloc() is marked as 0x7F. The MemoryContextCheck() is compiled '#ifdef USE_ASSERT_CHECKING'. I add this checking to 'tcop/postgres.c' and is active after each backend query, but it is probably not sufficient, because some MemoryContext exist only during memory processing --- will good if someone who known where it is needful (Tom:-) add it for others contexts; A problem in the current source is that we have still some malloc() allocation that is not needful and this allocation is total invisible for all context routines. For example Dllist in backend (pretty dirty it is in catcache where values in Dllist are palloc-ed, but list is malloc-ed). --- and BTW. this Dllist design stand in the way for query cache :-) Tom, if you agree I start replace some mallocs. BTW. --- Tom, have you idea for across transaction presistent allocation for SQL functions? (like regex - now it is via malloc) I almost forget. I add one if() to AllocSetAlloc(), for 'size' that are greater than ALLOC_BIGCHUNK_LIMIT is not needful check AllocSetFreeIndex(), because 'fidx' is always 'ALLOCSET_NUM_FREELISTS - 1'. It a little brisk up allocation for very large chunks. Right? Karel
* First phase of memory management rewrite (see backend/utils/mmgr/READMETom Lane2000-06-28
| | | | | | | | | | | | | 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.

| | | | | | | | | | ALLOC_BIGCHUNK_LIMIT are always allocated as separate malloc() blocks, and are free()d immediately upon pfree(). Also, if such a chunk is enlarged with repalloc(), translate the operation into a realloc() so as to minimize memory usage. Of course, these large chunks still get freed automatically if the alloc set is reset. I have set ALLOC_BIGCHUNK_LIMIT at 64K for now, but perhaps another size would be better?

* From: Ryan Kirkpatrick <rkirkpat@nag.cs.colorado.edu>Marc G. Fournier1998-04-27
| | | | | | | | | | Ok, I have finally gotten all of the defines for Dec/Alpha and Linux/Alpha sorted out as Marc asked. There is no longer any need for '-Dalpha' or '-Dlinuxalpha' in either the Dec/Alpha or the Linux/Alpha template files (./src/template/{alpha,linuxalpha}). I have replaced every instance of 'alpha' or '__alpha__' with '__alpha', as that appears to be the common symbol between C compilers on both operating systems (RH4.2 & DecUnix 4.0b) for alpha.

| | | | | | | | | | Subject: [HACKERS] linux/alpha patches These patches lay the groundwork for a Linux/Alpha port. The port doesn't actually work unless you tweak the linker to put all the pointers in the first 32 bits of the address space, but it's at least a start. It implements the test-and-set instruction in Alpha assembly, and also fixes a lot of pointer-to-integer conversions, which is probably good anyway.
