|
1. The documentation is now supplied in plain text form and HTML as well as in |
| 9 |
|
the form of man page sources. |
| 10 |
|
|
| 11 |
|
2. C++ compilers don't like assigning (void *) values to other pointer types. |
| 12 |
|
In particular this affects malloc(). Although there is no problem in Standard |
| 13 |
|
C, I've put in casts to keep C++ compilers happy. |
| 14 |
|
|
| 15 |
|
3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call |
| 16 |
|
should be (const char *). |
| 17 |
|
|
| 18 |
|
4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may |
| 19 |
|
be useful for non-Unix systems who don't want to bother with the POSIX stuff. |
| 20 |
|
However, I haven't made this a standard facility. The documentation doesn't |
| 21 |
|
mention it, and the Makefile doesn't support it. |
| 22 |
|
|
| 23 |
|
5. The Makefile now contains an "install" target, with editable destinations at |
| 24 |
|
the top of the file. The pcretest program is not installed. |
| 25 |
|
|
| 26 |
|
6. pgrep -V now gives the PCRE version number and date. |
| 27 |
|
|
| 28 |
|
7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was |
| 29 |
|
causing the entire string to be ignored, instead of just the last character. |
| 30 |
|
|
| 31 |
|
8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a |
| 32 |
|
non-matching string, it can take a very, very long time, even for strings of |
| 33 |
|
quite modest length, because of the nested recursion. PCRE now does better in |
| 34 |
|
some of these cases. It does this by remembering the last required literal |
| 35 |
|
character in the pattern, and pre-searching the subject to ensure it is present |
| 36 |
|
before running the real match. In other words, it applies a heuristic to detect |
| 37 |
|
some types of certain failure quickly, and in the above example, if presented |
| 38 |
|
with a string that has no trailing " it gives "no match" very quickly. |
| 39 |
|
|
| 40 |
|
9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored; |
| 41 |
|
other alternatives are tried instead. |
