| | | | | | | | | | | | | | | indexes. 1. Index Scan using plural indexids never scan backward as to the order of indexids. 2. The cursor using Index scan is not usable after moving past the end. This patch solves above bugs. Moreover the change of _bt_first() would be useful to extend ORDER BY patch by Jan Wieck for all descending order cases. Hiroshi Inoue
* From: Tatsuo Ishii <t-ishii@sra.co.jp>Marc G. Fournier1999-02-21
| | | | | | Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef NOT_USED" for current. I have tested these patches in that the postgres binaries are identical.

| | | | | | | | | | | | | | | | | | | | | | | | yyerror ones from bison. It also includes a few 'enhancements' to the C programming style (which are, of course, personal). The other patch removes the compilation of backend/lib/qsort.c, as qsort() is a standard function in stdlib.h and can be used any where else (and it is). It was only used in backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c, and backend/storage/page/bufpage.c > > Some or all of these changes might not be appropriate for v6.3, since we > > are in beta testing and since they do not affect the current functionality. > > For those cases, how about submitting patches based on the final v6.3 > > release? There's more to come. Please review these patches. I ran the regression tests and they only failed where this was expected (random, geo, etc). Cheers, Jeroen

| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | I found another bug in btree index. Looking at the code it seems that NULL keys are never used to build or scan a btree index (see the explain commands in the example). However this is not the case when a null key is retrieved in an outer loop of a join select and used in an index scan of an inner loop. This bug causes at least three kinds of problems: 1) the backend crashes when it tries to compare a text string with a null. 2) it is not possible to find tuples with null keys in a join. 3) null is considered equal to 0 when the datum is passed by value, see the last query.
