1999-06-12Reversed out Massimo patch.Bruce Momjian
1999-06-12I don't like last minute patches before the final freeze, but I believe thatBruce Momjian
this one could be useful for people experiencing out-of-memory crashes while executing queries which retrieve or use a very large number of tuples. The problem happens when storage is allocated for functions results used in a large query, for example: select upper(name) from big_table; select big_table.array[1] from big_table; select count(upper(name)) from big_table; This patch is a dirty hack that fixes the out-of-memory problem for the most common cases, like the above ones. It is not the final solution for the problem but it can work for some people, so I'm posting it. The patch should be safe because all changes are under #ifdef. Furthermore the feature can be enabled or disabled at runtime by the `free_tuple_memory' options in the pg_options file. The option is disabled by default and must be explicitly enabled at runtime to have any effect. To enable the patch add the follwing line to Makefile.custom: CUSTOM_COPT += -DFREE_TUPLE_MEMORY To enable the option at runtime add the following line to pg_option: free_tuple_memory=1 Massimo

1998-09-01OK, folks, here is the pgindent output.Bruce Momjian
1998-09-01Renaming cleanup, no pgindent yet.Bruce Momjian
1998-08-19heap_fetch requires buffer pointer, must be released; heap_getnextBruce Momjian
no longer returns buffer pointer, can be gotten from scan; descriptor; bootstrap can create multi-key indexes; pg_procname index now is multi-key index; oidint2, oidint4, oidname are gone (must be removed from regression tests); use System Cache rather than sequential scan in many places; heap_modifytuple no longer takes buffer parameter; remove unused buffer parameter in a few other functions; oid8 is not index-able; remove some use of single-character variable names; cleanup Buffer variables usage and scan descriptor looping; cleaned up allocation and freeing of tuples; 18k lines of diff;

First file of, what...1000's?
1996-09-19A few changes to cleanup the code.Marc G. Fournier
- Added the header access/heapam.h. - Changed all instances of "length" to "data_length" to quiet the compiler. - initialized a few variables. The compiler couldn't see that the code guaranteed that these would be initialized before being dereferenced. If anyone wants to check my work follow the usage of these variables and make sure that this true and wasn't actually a bug in the original code. - added a missing break statement to a default case. This was a benign error but bad style. - layed out heap_sysattrlen differently. I think this way makes the structure of the code crystal clear. There should be no actual difference in the actual behaviour of the code. Submitted by: darcy@druid.druid.com (D'Arcy J.M. Cain)
