|
2. JIT compiler now supports OP_NCREF, OP_RREF and OP_NRREF. New test cases |
| 10 |
|
are added as well. |
| 11 |
|
|
| 12 |
|
3. Fix cache-flush issue on PowerPC (It is still an experimental JIT port). |
| 13 |
|
PCRE_EXTRA_TABLES is not suported by JIT, and should be checked before |
| 14 |
|
calling _pcre_jit_exec. Some extra comments are added. |
| 15 |
|
|
| 16 |
|
4. Mark settings inside atomic groups that do not contain any capturing |
| 17 |
|
parentheses, for example, (?>a(*:m)), were not being passed out. This bug |
| 18 |
|
was introduced by change 18 for 8.20. |
| 19 |
|
|
| 20 |
|
5. Supporting of \x, \U and \u in JavaScript compatibility mode based on the |
| 21 |
|
ECMA-262 standard. |
| 22 |
|
|
| 23 |
|
6. Lookbehinds such as (?<=a{2}b) that contained a fixed repetition were |
| 24 |
|
erroneously being rejected as "not fixed length" if PCRE_CASELESS was set. |
| 25 |
|
This bug was probably introduced by change 9 of 8.13. |
| 26 |
|
|
| 27 |
|
7. While fixing 6 above, I noticed that a number of other items were being |
| 28 |
|
incorrectly rejected as "not fixed length". This arose partly because newer |
| 29 |
|
opcodes had not been added to the fixed-length checking code. I have (a) |
| 30 |
|
corrected the bug and added tests for these items, and (b) arranged for an |
| 31 |
|
error to occur if an unknown opcode is encountered while checking for fixed |
| 32 |
|
length instead of just assuming "not fixed length". The items that were |
| 33 |
|
rejected were: (*ACCEPT), (*COMMIT), (*FAIL), (*MARK), (*PRUNE), (*SKIP), |
| 34 |
|
(*THEN), \h, \H, \v, \V, and single character negative classes with fixed |
| 35 |
|
repetitions, e.g. [^a]{3}, with and without PCRE_CASELESS. |
| 36 |
|
|
| 37 |
|
8. A possessively repeated conditional subpattern such as (?(?=c)c|d)++ was |
| 38 |
|
being incorrectly compiled and would have given unpredicatble results. |
| 39 |
|
|
| 40 |
|
9. A possessively repeated subpattern with minimum repeat count greater than |
| 41 |
|
one behaved incorrectly. For example, (A){2,}+ behaved as if it was |
| 42 |
|
(A)(A)++ which meant that, after a subsequent mismatch, backtracking into |
| 43 |
|
the first (A) could occur when it should not. |
| 44 |
|
|
| 45 |
|
10. Add a cast and remove a redundant test from the code. |
| 46 |
|
|
| 47 |
|
11. JIT should use pcre_malloc/pcre_free for allocation. |
| 48 |
|
|
| 49 |
|
12. Updated pcre-config so that it no longer shows -L/usr/lib, which seems |
| 50 |
|
best practice nowadays, and helps with cross-compiling. (If the exec_prefix |
| 51 |
|
is anything other than /usr, -L is still shown). |
| 52 |
|
|
| 53 |
|
13. In non-UTF-8 mode, \C is now supported in lookbehinds and DFA matching. |
| 54 |
|
|
| 55 |
|
14. Perl does not support \N without a following name in a [] class; PCRE now |
| 56 |
|
also gives an error. |
