Version 3.2 12-May-00 |
| 6 |
|
--------------------- |
| 7 |
|
|
| 8 |
|
This is purely a bug fixing release. |
| 9 |
|
|
| 10 |
|
1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead |
| 11 |
|
of ZA. This was just one example of several cases that could provoke this bug, |
| 12 |
|
which was introduced by change 9 of version 2.00. The code for breaking |
| 13 |
|
infinite loops after an iteration that matches an empty string was't working |
| 14 |
|
correctly. |
| 15 |
|
|
| 16 |
|
2. The pcretest program was not imitating Perl correctly for the pattern /a*/g |
| 17 |
|
when matched against abbab (for example). After matching an empty string, it |
| 18 |
|
wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this |
| 19 |
|
caused it to match further down the string than it should. |
| 20 |
|
|
| 21 |
|
3. The code contained an inclusion of sys/types.h. It isn't clear why this |
| 22 |
|
was there because it doesn't seem to be needed, and it causes trouble on some |
| 23 |
|
systems, as it is not a Standard C header. It has been removed. |
| 24 |
|
|
| 25 |
|
4. Made 4 silly changes to the source to avoid stupid compiler warnings that |
| 26 |
|
were reported on the Macintosh. The changes were from |
| 27 |
|
|
| 28 |
|
while ((c = *(++ptr)) != 0 && c != '\n'); |
| 29 |
|
to |
| 30 |
|
while ((c = *(++ptr)) != 0 && c != '\n') ; |
| 31 |
|
|
| 32 |
|
Totally extraordinary, but if that's what it takes... |
| 33 |
|
|
| 34 |
|
5. PCRE is being used in one environment where neither memmove() nor bcopy() is |
| 35 |
|
available. Added HAVE_BCOPY and an autoconf test for it; if neither |
| 36 |
|
HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which |
| 37 |
|
assumes the way PCRE uses memmove() (always moving upwards). |
| 38 |
|
|
| 39 |
|
6. PCRE is being used in one environment where strchr() is not available. There |
| 40 |
|
was only one use in pcre.c, and writing it out to avoid strchr() probably gives |
| 41 |
|
faster code anyway. |
| 42 |

Version 3.1 09-Feb-00 |
| 45 |
|
--------------------- |
| 46 |
|
|
| 47 |
|
The only change in this release is the fixing of some bugs in Makefile.in for |
| 48 |
|
the "install" target: |
| 49 |
|
|
| 50 |
|
(1) It was failing to install pcreposix.h. |
| 51 |
|
|
| 52 |
|
(2) It was overwriting the pcre.3 man page with the pcreposix.3 man page. |
| 53 |
|
|
| 54 |
|
|
| 55 |
|
Version 3.0 01-Feb-00 |
| 56 |
|
--------------------- |
| 57 |
|
|
| 58 |
|
1. Add support for the /+ modifier to perltest (to output $` like it does in |
| 59 |
|
pcretest). |
| 60 |
|
|
| 61 |
|
2. Add support for the /g modifier to perltest. |
| 62 |
|
|
| 63 |
|
3. Fix pcretest so that it behaves even more like Perl for /g when the pattern |
| 64 |
|
matches null strings. |
| 65 |
|
|
| 66 |
|
4. Fix perltest so that it doesn't do unwanted things when fed an empty |
| 67 |
|
pattern. Perl treats empty patterns specially - it reuses the most recent |
| 68 |
|
pattern, which is not what we want. Replace // by /(?#)/ in order to avoid this |
| 69 |
|
effect. |
| 70 |
|
|
| 71 |
|
5. The POSIX interface was broken in that it was just handing over the POSIX |
| 72 |
|
captured string vector to pcre_exec(), but (since release 2.00) PCRE has |
| 73 |
|
required a bigger vector, with some working space on the end. This means that |
| 74 |
|
the POSIX wrapper now has to get and free some memory, and copy the results. |
| 75 |
|
|
| 76 |
|
6. Added some simple autoconf support, placing the test data and the |
| 77 |
|
documentation in separate directories, re-organizing some of the |
| 78 |
|
information files, and making it build pcre-config (a GNU standard). Also added |
| 79 |
|
libtool support for building PCRE as a shared library, which is now the |
| 80 |
|
default. |
| 81 |
|
|
| 82 |
|
7. Got rid of the leading zero in the definition of PCRE_MINOR because 08 and |
| 83 |
|
09 are not valid octal constants. Single digits will be used for minor values |
| 84 |
|
less than 10. |
| 85 |
|
|
| 86 |
|
8. Defined REG_EXTENDED and REG_NOSUB as zero in the POSIX header, so that |
| 87 |
|
existing programs that set these in the POSIX interface can use PCRE without |
| 88 |
|
modification. |
| 89 |
|
|
| 90 |
|
9. Added a new function, pcre_fullinfo() with an extensible interface. It can |
| 91 |
|
return all that pcre_info() returns, plus additional data. The pcre_info() |
| 92 |
|
function is retained for compatibility, but is considered to be obsolete. |
| 93 |
|
|
| 94 |
|
10. Added experimental recursion feature (?R) to handle one common case that |
| 95 |
|
Perl 5.6 will be able to do with (?p{...}). |
| 96 |
|
|
| 97 |
|
11. Added support for POSIX character classes like [:alpha:], which Perl is |
| 98 |
|
adopting. |
| 99 |

|
Version 2.08 31-Aug-99 |
| 102 |
|
---------------------- |
| 103 |
|
|
| 104 |
|
1. When startoffset was not zero and the pattern began with ".*", PCRE was not |
| 105 |
|
trying to match at the startoffset position, but instead was moving forward to |
| 106 |
|
the next newline as if a previous match had failed. |
| 107 |
|
|
| 108 |
|
2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G, |
| 109 |
|
and could get into a loop if a null string was matched other than at the start |
| 110 |
|
of the subject. |
| 111 |
|
|
| 112 |
|
3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can |
| 113 |
|
be distinguished at compile time, and for completeness also added PCRE_DATE. |
| 114 |
|
|
| 115 |
|
5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL |
| 116 |
|
in GnuWin32 environments. |
