|
1. Change pcretest's output for amount of store used to show just the code |
| 9 |
|
space, because the remainder (the data block) varies in size between 32-bit and |
| 10 |
|
64-bit systems. |
| 11 |
|
|
| 12 |
|
2. Added an extra argument to pcre_exec() to supply an offset in the subject to |
| 13 |
|
start matching at. This allows lookbehinds to work when searching for multiple |
| 14 |
|
occurrences in a string. |
| 15 |
|
|
| 16 |
|
3. Added additional options to pcretest for testing multiple occurrences: |
| 17 |
|
|
| 18 |
|
/+ outputs the rest of the string that follows a match |
| 19 |
|
/g loops for multiple occurrences, using the new startoffset argument |
| 20 |
|
/G loops for multiple occurrences by passing an incremented pointer |
| 21 |
|
|
| 22 |
|
4. PCRE wasn't doing the "first character" optimization for patterns starting |
| 23 |
|
with \b or \B, though it was doing it for other lookbehind assertions. That is, |
| 24 |
|
it wasn't noticing that a match for a pattern such as /\bxyz/ has to start with |
| 25 |
|
the letter 'x'. On long subject strings, this gives a significant speed-up. |

|
1. Changed the type of magic_number from int to long int so that it works |
| 32 |
|
properly on 16-bit systems. |
| 33 |
|
|
| 34 |
|
2. Fixed a bug which caused patterns starting with .* not to work correctly |
| 35 |
|
when the subject string contained newline characters. PCRE was assuming |
| 36 |
|
anchoring for such patterns in all cases, which is not correct because .* will |
| 37 |
|
not pass a newline unless PCRE_DOTALL is set. It now assumes anchoring only if |
| 38 |
|
DOTALL is set at top level; otherwise it knows that patterns starting with .* |
| 39 |
|
must be retried after every newline in the subject. |
