* | * lib.c (length_str_gt, length_str_ge, length_str_lt, length_str_le): | Kaz Kylheku | 2010-02-28 | 2 | -36/+69 | |
| | | | | Added missing support for literal string type. | |||||
* | * lib.c (search_str): Bugfix for empty haystack case: checks for end | Kaz Kylheku | 2010-02-27 | 2 | -2/+8 | |
| | | | | | of string must use postincrement on the index, otherwise the access goes past the null terminator. | |||||
* | * match.c (match_lines): Bugfix in freeform directive. | Kaz Kylheku | 2010-02-27 | 2 | -1/+14 | |
| | | | | | | | | | | If the virtual line is partially matched, the remainder of the line is folded back into list form. In this case, the data line number must be incremented. Otherwise the calling context may conclude that no progress was made, and skip a line of input. I.e. the unmatched part of the input is a new line, even if there had originally been no line break at that point. | |||||
* | * lib.h (split_str_sep): Declared. | Kaz Kylheku | 2010-02-27 | 3 | -5/+34 | |
| | | | | | | | | | * lib.c (split_str_sep): New function. (split_str): Semantics changed; the second argument is not a set of separator characters (like in split_str_sep) but rather a separator string. Fixed bug: if the input string is empty, the output list is empty. This caused infinite looping behavior in @(freeform). | |||||
* | * lib.c (init_str): Bugfix: copy only len characters, not len + 1, so | Kaz Kylheku | 2010-02-24 | 2 | -1/+8 | |
| | | | | | | that we don't clobber the null terminator in the target string, or try read past the end of the source data. This affects the @(freeform) directive. | |||||

| | | | | | | the type codes of spuriously reached nodes; reached objects will not be removed by weak processing and so it's better to just detect those situations and short-circuit. | |||||

* | Optimization in derivative-based regex engine. | Kaz Kylheku | 2010-01-26 | 4 | -1/+91 | |
| | | | | | | | | Exponential memory consumption behavior was observed when matching the input aaaaaa.... against the regex a?a?a?a?....aaaa.... The fix is to eliminate common subexpressions from the derivative for the or operator. | |||||

* | * match.c (match_files): Workaround for GC issue | Kaz Kylheku | 2010-01-24 | 2 | -0/+10 | |
| | | | | | | | discovered on Red Hat EL 4 with gcc 3.4.3. In the collect loop, set car(success) to nil. Somehow the generated code hangs on to the last matching position for a regex, preventing GC. | |||||

| | | | | | | on 32 bit x86 Fedora. This happens because the lazy list variable ``data'' in the match_files function is optimized to a register, but a stale value of that variable persists in the backing storage. | |||||

* | * regex.c (reg_derivative_list, reg_derivative): Recognition | Kaz Kylheku | 2010-01-18 | 2 | -6/+39 | |
| | | | | | | | | | of cases to reduce consing. In reg_derivative_list, we avoid consing the full or expression if either branch is t, and also save a cons when the first element has a null derivative. In reg_derivative the oneplus and zeroplus cases are split, since zeroplus can re-use the input expression, when it's just a one-character match, deriving nil. | |||||
* | Adjust semantics of non-greedy operator R%S, to avoid the broken | Kaz Kylheku | 2010-01-18 | 3 | -21/+41 | |
| | | | | | | | | case whereby R%S matches nothing at all when S is not empty but equivalent to empty, or more generally when S is nullable. A much nicer definition is ``the intersection of R* and the set of all strings that do not contain a non-empty substring that matches S, followed by S''. | |||||
