|
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. |
