13. In non-UTF-8 mode, \C is now supported in lookbehinds and DFA matching. |

14. Perl does not support \N without a following name in a [] class; PCRE now |
| 56 |
|
also gives an error. |
| 57 |
|
|
| 58 |
|
15. If a forward reference was repeated with an upper limit of around 2000, |
| 59 |
|
it caused the error "internal error: overran compiling workspace". The |
| 60 |
|
maximum number of forward references (including repeats) was limited by the |
| 61 |
|
internal workspace, and dependent on the LINK_SIZE. The code has been |
| 62 |
|
rewritten so that the workspace expands (via pcre_malloc) if necessary, and |
| 63 |
|
the default depends on LINK_SIZE. There is a new upper limit (for safety) |
| 64 |
|
of around 200,000 forward references. While doing this, I also speeded up |
| 65 |
|
the filling in of repeated forward references. |
| 66 |
|
|
| 67 |
|
16. A repeated forward reference in a pattern such as (a)(?2){2}(.) was |
| 68 |
|
incorrectly expecting the subject to contain another "a" after the start. |
| 69 |
|
|
| 70 |
|
17. When (*SKIP:name) is activated without a corresponding (*MARK:name) earlier |
| 71 |
|
in the match, the SKIP should be ignored. This was not happening; instead |
| 72 |
|
the SKIP was being treated as NOMATCH. For patterns such as |
| 73 |
|
/A(*MARK:A)A+(*SKIP:B)Z|AAC/ this meant that the AAC branch was never |
| 74 |
|
tested. |
| 75 |
|
|
| 76 |
|
18. The behaviour of (*MARK), (*PRUNE), and (*THEN) has been reworked and is |
| 77 |
|
now much more compatible with Perl, in particular in cases where the result |
| 78 |
|
is a non-match for a non-anchored pattern. For example, if |
| 79 |
|
/b(*:m)f|a(*:n)w/ is matched against "abc", the non-match returns the name |
| 80 |
|
"m", where previously it did not return a name. A side effect of this |
| 81 |
|
change is that for partial matches, the last encountered mark name is |
| 82 |
|
returned, as for non matches. A number of tests that were previously not |
| 83 |
|
Perl-compatible have been moved into the Perl-compatible test files. The |
| 84 |
|
refactoring has had the pleasing side effect of removing one argument from |
| 85 |
|
the match() function, thus reducing its stack requirements. |
| 86 |
|
|
| 87 |
|
19. If the /S+ option was used in pcretest to study a pattern using JIT, |
| 88 |
|
subsequent uses of /S (without +) incorrectly behaved like /S+. |
| 89 |

|
21. Retrieve executable code size support for the JIT compiler and fixing |
| 91 |
|
some warnings. |
| 92 |
|
|
| 93 |
|
22. A caseless match of a UTF-8 character whose other case uses fewer bytes did |
| 94 |
|
not work when the shorter character appeared right at the end of the |
| 95 |
|
subject string. |
| 96 |
|
|
| 97 |
|
23. Added some (int) casts to non-JIT modules to reduce warnings on 64-bit |
| 98 |
|
systems. |
