./devel/pcre, Perl Compatible Regular Expressions library

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 8.40nb1, Package name: pcre-8.40nb1, Maintainer: pkgsrc-users

PCRE is a Perl compatible library of regular expressions. They
are based on a completely separate code-base from Henry Spencers
originals. It has been designed to make efficient use of memory
for compiled regex's.

Log message:
Updated pcre to 8.39.

Release 8.39 14-June-2016
-------------------------

Some appropriate PCRE2 JIT improvements have been retro-fitted to PCRE1. Apart
from that, this is another bug-fix release. Note that this library (now called
PCRE1) is now being maintained for bug fixes only. New projects are advised to
use the new PCRE2 libraries.

Log message:
Update pcre to 8.38:

Version 8.38 23-November-2015
-----------------------------

1.  If a group that contained a recursive back reference also contained a
    forward reference subroutine call followed by a non-forward-reference
    subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to
    compile correct code, leading to undefined behaviour or an internally
    detected error. This bug was discovered by the LLVM fuzzer.

2.  Quantification of certain items (e.g. atomic back references) could cause
    incorrect code to be compiled when recursive forward references were
    involved. For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/.
    This bug was discovered by the LLVM fuzzer.

3.  A repeated conditional group whose condition was a reference by name caused
    a buffer overflow if there was more than one group with the given name.
    This bug was discovered by the LLVM fuzzer.

4.  A recursive back reference by name within a group that had the same name as
    another group caused a buffer overflow. For example:
    /(?J)(?'d'(?'d'\g{d}))/. This bug was discovered by the LLVM fuzzer.

5.  A forward reference by name to a group whose number is the same as the
    current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused
    a buffer overflow at compile time. This bug was discovered by the LLVM
    fuzzer.

6.  A lookbehind assertion within a set of mutually recursive subpatterns could
    provoke a buffer overflow. This bug was discovered by the LLVM fuzzer.

7.  Another buffer overflow bug involved duplicate named groups with a
    reference between their definition, with a group that reset capture
    numbers, for example: /(?J:(?|(?'R')(\k'R')|((?'R'))))/. This has been
    fixed by always allowing for more memory, even if not needed. (A proper fix
    is implemented in PCRE2, but it involves more refactoring.)

8.  There was no check for integer overflow in subroutine calls such as (?123).

9.  The table entry for \l in EBCDIC environments was incorrect, leading to its
    being treated as a literal 'l' instead of causing an error.

10. There was a buffer overflow if pcre_exec() was called with an ovector of
    size 1. This bug was found by american fuzzy lop.

11. If a non-capturing group containing a conditional group that could match
    an empty string was repeated, it was not identified as matching an empty
    string itself. For example: /^(?:(?(1)x|)+)+$()/.

12. In an EBCDIC environment, pcretest was mishandling the escape sequences
    \a and \e in test subject lines.

13. In an EBCDIC environment, \a in a pattern was converted to the ASCII
    instead of the EBCDIC value.

14. The handling of \c in an EBCDIC environment has been revised so that it is
    now compatible with the specification in Perl's perlebcdic page.

15. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in
    ASCII/Unicode. This has now been added to the list of characters that are
    recognized as white space in EBCDIC.

16. When PCRE was compiled without UCP support, the use of \p and \P gave an
    error (correctly) when used outside a class, but did not give an error
    within a class.

17. \h within a class was incorrectly compiled in EBCDIC environments.

18. A pattern with an unmatched closing parenthesis that contained a backward
    assertion which itself contained a forward reference caused buffer
    overflow. And example pattern is: /(?=di(?<=(?1))|(?=(.))))/.

19. JIT should return with error when the compiled pattern requires more stack
    space than the maximum.

20. A possessively repeated conditional group that could match an empty string,
    for example, /(?(R))*+/, was incorrectly compiled.

21. Fix infinite recursion in the JIT compiler when certain patterns such as
    /(?:|a|){100}x/ are analysed.

22. Some patterns with character classes involving [: and \\ were incorrectly
    compiled and could cause reading from uninitialized memory or an incorrect
    error diagnosis.

23. Pathological patterns containing many nested occurrences of [: caused
    pcre_compile() to run for a very long time.

24. A conditional group with only one branch has an implicit empty alternative
    branch and must therefore be treated as potentially matching an empty
    string.

25. If (?R was followed by - or + incorrect behaviour happened instead of a
    diagnostic.

26. Arrange to give up on finding the minimum matching length for overly
    complex patterns.

27. Similar to (4) above: in a pattern with duplicated named groups and an
    occurrence of (?| it is possible for an apparently non-recursive back
    reference to become recursive if a later named group with the relevant
    number is encountered. This could lead to a buffer overflow. Wen Guanxing
    from Venustech ADLAB discovered this bug.

28. If pcregrep was given the -q option with -c or -l, or when handling a
    binary file, it incorrectly wrote output to stdout.

29. The JIT compiler did not restore the control verb head in case of *THEN
    control verbs. This issue was found by Karl Skomski with a custom LLVM
    fuzzer.

30. Error messages for syntax errors following \g and \k were giving inaccurate
    offsets in the pattern.

31. Added a check for integer overflow in conditions (?(<digits>) and
    (?(R<digits>). This omission was discovered by Karl Skomski with the LLVM
    fuzzer.

32. Handling recursive references such as (?2) when the reference is to a group
    later in the pattern uses code that is very hacked about and error-prone.
    It has been re-written for PCRE2. Here in PCRE1, a check has been added to
    give an internal error if it is obvious that compiling has gone wrong.

33. The JIT compiler should not check repeats after a {0,1} repeat byte code.
    This issue was found by Karl Skomski with a custom LLVM fuzzer.

34. The JIT compiler should restore the control chain for empty possessive
    repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer.

35. Match limit check added to JIT recursion. This issue was found by Karl
    Skomski with a custom LLVM fuzzer.

36. Yet another case similar to 27 above has been circumvented by an
    unconditional allocation of extra memory. This issue is fixed \ 
"properly" in
    PCRE2 by refactoring the way references are handled. Wen Guanxing
    from Venustech ADLAB discovered this bug.

37. Fix two assertion fails in JIT. These issues were found by Karl Skomski
    with a custom LLVM fuzzer.

38. Fixed a corner case of range optimization in JIT.

39. An incorrect error "overran compiling workspace" was given if \ 
there were
    exactly enough group forward references such that the last one extended
    into the workspace safety margin. The next one would have expanded the
    workspace. The test for overflow was not including the safety margin.

40. A match limit issue is fixed in JIT which was found by Karl Skomski
    with a custom LLVM fuzzer.

41. Remove the use of /dev/null in testdata/testinput2, because it doesn't
    work under Windows. (Why has it taken so long for anyone to notice?)

42. In a character class such as [\W\p{Any}] where both a negative-type escape
    ("not a word character") and a property escape were present, the \ 
property
    escape was being ignored.

43. Fix crash caused by very long (*MARK) or (*THEN) names.

44. A sequence such as [[:punct:]b] that is, a POSIX character class followed
    by a single ASCII character in a class item, was incorrectly compiled in
    UCP mode. The POSIX class got lost, but only if the single character
    followed it.

45. [:punct:] in UCP mode was matching some characters in the range 128-255
    that should not have been matched.

46. If [:^ascii:] or [:^xdigit:] or [:^cntrl:] are present in a non-negated
    class, all characters with code points greater than 255 are in the class.
    When a Unicode property was also in the class (if PCRE_UCP is set, escapes
    such as \w are turned into Unicode properties), wide characters were not
    correctly handled, and could fail to match.
