Tom Lane 3694b4d7e1 Fix incorrect search for "x?" style matches in creviterdissect(). ... When the number of allowed iterations is limited (either a "?" quantifier or a bound expression), the last sub-match has to reach to the end of the target string. The previous coding here first tried the shortest possible match (one character, usually) and then gave up and back-tracked if that didn't work, typically leading to failure to match overall, as shown in bug #11478 from Christoph Berg. The minimum change to fix that would be to not decrement k before "goto backtrack"; but that would be a pretty stupid solution, because we'd laboriously try each possible sub-match length before finally discovering that only ending at the end can work. Instead, force the sub-match endpoint limit up to the end for even the first shortest() call if we cannot have any more sub-matches after this one. Bug introduced in my rewrite that added the iterdissect logic, commit 173e29aa5d. The shortest-first search code was too closely modeled on the longest-first code, which hasn't got this issue since it tries a match reaching to the end to start with anyway. Back-patch to all affected branches.		2014-09-23 20:26:14 -04:00
