* | fix a tiny performance bug in our string search that we ported from cpython.Carl Friedrich Bolz-Tereick2021-02-253-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | the condition is a bit complicated: - we need a last character that is unique in the string - we are at a position in the string that matches the last character, but a previous char is a mismatch - the next char in the haystack is in the bloom filter if all this is met, we want to skip a whole needle length, not len(needle) - 1 this was pointed out by Tim Peters here: https://bugs.python.org/msg378301

| | | | | | | | | | | | | | | | | | the py3.7 branch The test produces stack overflows intentionally, and if we blackhole at the wrong stack depth then an vmprof frame is not popped correctly for some reason. unfortunately I was not able to find the reason, but this mitigation at least prevents the vm from crashing.
