Tom Lane 587359479a Avoid repeated creation/freeing of per-subre DFAs during regex search. ... In nested sub-regex trees, lower-level nodes created DFAs and then destroyed them again before exiting, which is a bit dumb considering that the recursive search is likely to call those nodes again later. Instead cache each created DFA until the end of pg_regexec(). This is basically a space for time tradeoff, in that it might increase the maximum memory usage. However, in most regex patterns there are not all that many subre nodes, so not that many DFAs --- and in any case, the peak usage occurs when reaching the bottom recursion level, and except for alternation cases that's going to be the same anyway.		2012-02-24 18:40:30 -05:00
