1. If the fr_FR locale cannot be found for test 3, try the "french" locale, |
| 8 |
|
which is apparently normally available under Windows. |
| 9 |
|
|
| 10 |
|
2. Re-jig the pcregrep tests with different newline settings in an attempt |
| 11 |
|
to make them independent of the local environment's newline setting. |
| 12 |
|
|
| 13 |
|
3. Add code to configure.ac to remove -g from the CFLAGS default settings. |
| 14 |
|
|
| 15 |
|
4. Some of the "internals" tests were previously cut out when the link size |
| 16 |
|
was not 2, because the output contained actual offsets. The recent new |
| 17 |
|
"Z" feature of pcretest means that these can be cut out, making the tests |
| 18 |
|
usable with all link sizes. |
| 19 |
|
|
| 20 |
|
5. Implemented Stan Switzer's goto replacement for longjmp() when not using |
| 21 |
|
stack recursion. This gives a massive performance boost under BSD, but just |
| 22 |
|
a small improvement under Linux. However, it saves one field in the frame |
| 23 |
|
in all cases. |
| 24 |
|
|
| 25 |
|
6. Added more features from the forthcoming Perl 5.10: |
| 26 |
|
|
| 27 |
|
(a) (?-n) (where n is a string of digits) is a relative subroutine or |
| 28 |
|
recursion call. It refers to the nth most recently opened parentheses. |
| 29 |
|
|
| 30 |
|
(b) (?+n) is also a relative subroutine call; it refers to the nth next |
| 31 |
|
to be opened parentheses. |
| 32 |
|
|
| 33 |
|
(c) Conditions that refer to capturing parentheses can be specified |
| 34 |
|
relatively, for example, (?(-2)... or (?(+3)... |
| 35 |
|
|
| 36 |
|
(d) \K resets the start of the current match so that everything before |
| 37 |
|
is not part of it. |
| 38 |

22. Code for handling Unicode properties in pcre_dfa_exec() wasn't being cut |
| 183 |
|
out by #ifdef SUPPORT_UCP. This did no harm, as it could never be used, but |
| 184 |
|
I have nevertheless tidied it up. |

23. Added some casts to kill warnings from HP-UX ia64 compiler. |

24. Added a man page for pcre-config. |
