* Document VIS_HTTPSTYLE:Alexander Langer2000-07-022-4/+34
| | | | | | | | | | | | | | | | VIS_HTTPSTYLE is a new encoding style for use in vis(), strvis() and strvisx() that escapes characters according to RFC 1808 (URI encoding). Since decoding of these require different detection of start-points of escaped characters, VIS_HTTPSTYLE can be given as flag to unvis(). unvis() will then properly decode URIs. A new function appeared, strunvisx(): strunvisx() behaves similar as strunvis(), with one exception: It has an additional flag parameter, which is passed to unvis() to archive the effect I described above.

* Enhance the optimization provided by pre-matching. Fix style bugs withDaniel C. Sobral2000-07-023-12/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | previous commits. At the time we search the pattern for the "must" string, we now compute the longest offset from the beginning of the pattern at which the must string might be found. If that offset is found to be infinite (through use of "+" or "*"), we set it to -1 to disable the heuristics applied later. After we are done with pre-matching, we use that offset and the point in the text at which the must string was found to compute the earliest point at which the pattern might be found. Special care should be taken here. The variable "start" is passed to the automata-processing functions fast() and slow() to indicate the point in the text at which they should start working from. The real beginning of the text is passed in a struct match variable m, which is used to check for anchors. That variable, though, is initialized with "start", so we must not adjust "start" before "m" is properly initialized. Simple tests showed a speed increase from 100% to 400%, but they were biased in that regexec() was called for the whole file instead of line by line, and parenthized subexpressions were not searched for. This change adds a single integer to the size of the "guts" structure, and does not change the ABI. Further improvements possible: Since the speed increase observed here is so huge, one intuitive optimization would be to introduce a bias in the function that computes the "must" string so as to prefer a smaller string with a finite offset over a larger one with an infinite offset. Tests have shown this to be a bad idea, though, as the cost of false pre-matches far outweights the benefits of a must offset, even in biased situations. A number of other improvements suggest themselves, though: * identify the cases where the pattern is identical to the must string, and avoid entering fast() and slow() in these cases. * compute the maximum offset from the must string to the end of the pattern, and use that to set the point at which fast() and slow() should give up trying to find a match, and return then return to pre-matching. * return all the way to pre-matching if a "match" was found and later invalidated by back reference processing. Since back references are evil and should be avoided anyway, this is of little use. Notes: svn path=/head/; revision=62391

* Add Boyler-Moore algorithm to pre-matching test.Daniel C. Sobral2000-06-293-6/+202
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BM algorithm works by scanning the pattern from right to left, and jumping as many characters as viable based on the text's mismatched character and the pattern's already matched suffix. This typically enable us to test only a fraction of the text's characters, but has a worse performance than the straight-forward method for small patterns. Because of this, the BM algorithm will only be used if the pattern size is at least 4 characters. Notice that this pre-matching is done on the largest substring of the regular expression that _must_ be present on the text for a succesful match to be possible at all. For instance, "(xyzzy|grues)" will yield a null "must" substring, and, therefore, not benefit from the BM algorithm at all. Because of the lack of intelligence of the algorithm that finds the "must" string, things like "charjump|matchjump" will also yield a null string. To optimize that, "(char|match)jump" should be used. The setup time (at regcomp()) for the BM algorithm will most likely outweight any benefits for one-time matches. Given the slow regex(3) we have, this is unlikely to be even perceptible, though. The size of a regex_t structure is increased by 2*sizeof(char*) + 256*sizeof(int) + strlen(must)*sizeof(int). This is all inside the regex_t's "guts", which is allocated dynamically by regcomp(). If allocation of either of the two tables fail, the other one is freed. In this case, the straight-forward algorithm is used for pre-matching. Tests exercising the code path affected have shown a speed increase of 50% for "must" strings of length four or five. API and ABI remain unchanged by this commit. The patch submitted on the PR was not used, as it was non-functional. PR: 14342 Notes: svn path=/head/; revision=62232

| | | | | | | | | | | | | | | | | | not have a user-supplied signal handler, when a signal is delivered, one thread will receive the signal, and then the code reverts to having no signal handler for the signal. This can leave the other sigwait()ing threads stranded permanently if the signal is later ignored, or can result in process termination when the process should have delivered the signal to one of the threads in sigwait(). To fix this problem, maintain a count of sigwait()ers for each signal that has no default signal handler. Use the count to correctly install/uninstall dummy signal handlers.
