Version 3.4 22-Aug-00 |
| 6 |
|
--------------------- |
| 7 |
|
|
| 8 |
|
1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *. |
| 9 |
|
|
| 10 |
|
2. Diagnose condition (?(0) as an error instead of crashing on matching. |
| 11 |
|
|
| 12 |
|
|
| 13 |
|
Version 3.3 01-Aug-00 |
| 14 |
|
--------------------- |
| 15 |
|
|
| 16 |
|
1. If an octal character was given, but the value was greater than \377, it |
| 17 |
|
was not getting masked to the least significant bits, as documented. This could |
| 18 |
|
lead to crashes in some systems. |
| 19 |
|
|
| 20 |
|
2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats |
| 21 |
|
the hyphen as a literal. PCRE used to give an error; it now behaves like Perl. |
| 22 |
|
|
| 23 |
|
3. Added the functions pcre_free_substring() and pcre_free_substring_list(). |
| 24 |
|
These just pass their arguments on to (pcre_free)(), but they are provided |
| 25 |
|
because some uses of PCRE bind it to non-C systems that can call its functions, |
| 26 |
|
but cannot call free() or pcre_free() directly. |
| 27 |
|
|
| 28 |
|
4. Add "make test" as a synonym for "make check". Corrected some comments in |
| 29 |
|
the Makefile. |
| 30 |
|
|
| 31 |
|
5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the |
| 32 |
|
Makefile. |
| 33 |
|
|
| 34 |
|
6. Changed the name of pgrep to pcregrep, because Solaris has introduced a |
| 35 |
|
command called pgrep for grepping around the active processes. |
| 36 |
|
|
| 37 |
|
7. Added the beginnings of support for UTF-8 character strings. |
| 38 |
|
|
| 39 |
|
8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and |
| 40 |
|
RANLIB to ./ltconfig so that they are used by libtool. I think these are all |
| 41 |
|
the relevant ones. (AR is not passed because ./ltconfig does its own figuring |
| 42 |
|
out for the ar command.) |

Version 3.2 12-May-00 |
| 46 |
|
--------------------- |
| 47 |
|
|
| 48 |
|
This is purely a bug fixing release. |
| 49 |
|
|
| 50 |
|
1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead |
| 51 |
|
of ZA. This was just one example of several cases that could provoke this bug, |
| 52 |
|
which was introduced by change 9 of version 2.00. The code for breaking |
| 53 |
|
infinite loops after an iteration that matches an empty string was't working |
| 54 |
|
correctly. |
| 55 |
|
|
| 56 |
|
2. The pcretest program was not imitating Perl correctly for the pattern /a*/g |
| 57 |
|
when matched against abbab (for example). After matching an empty string, it |
| 58 |
|
wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this |
| 59 |
|
caused it to match further down the string than it should. |
| 60 |
|
|
| 61 |
|
3. The code contained an inclusion of sys/types.h. It isn't clear why this |
| 62 |
|
was there because it doesn't seem to be needed, and it causes trouble on some |
| 63 |
|
systems, as it is not a Standard C header. It has been removed. |
| 64 |
|
|
| 65 |
|
4. Made 4 silly changes to the source to avoid stupid compiler warnings that |
| 66 |
|
were reported on the Macintosh. The changes were from |
| 67 |
|
|
| 68 |
|
while ((c = *(++ptr)) != 0 && c != '\n'); |
| 69 |
|
to |
| 70 |
|
while ((c = *(++ptr)) != 0 && c != '\n') ; |
| 71 |
|
|
| 72 |
|
Totally extraordinary, but if that's what it takes... |
| 73 |
|
|
| 74 |
|
5. PCRE is being used in one environment where neither memmove() nor bcopy() is |
| 75 |
|
available. Added HAVE_BCOPY and an autoconf test for it; if neither |
| 76 |
|
HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which |
| 77 |
|
assumes the way PCRE uses memmove() (always moving upwards). |
| 78 |
|
|
| 79 |
|
6. PCRE is being used in one environment where strchr() is not available. There |
| 80 |
|
was only one use in pcre.c, and writing it out to avoid strchr() probably gives |
| 81 |
|
faster code anyway. |
