Version 3.5 15-Aug-01 |
| 5 |
|
--------------------- |
| 6 |
|
|
| 7 |
|
1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that |
| 8 |
|
had been forgotten. |
| 9 |
|
|
| 10 |
|
2. By using declared but undefined structures, we can avoid using "void" |
| 11 |
|
definitions in pcre.h while keeping the internal definitions of the structures |
| 12 |
|
private. |
| 13 |
|
|
| 14 |
|
3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a |
| 15 |
|
user point of view, this means that both static and shared libraries are built |
| 16 |
|
by default, but this can be individually controlled. More of the work of |
| 17 |
|
handling this static/shared cases is now inside libtool instead of PCRE's make |
| 18 |
|
file. |
| 19 |
|
|
| 20 |
|
4. The pcretest utility is now installed along with pcregrep because it is |
| 21 |
|
useful for users (to test regexs) and by doing this, it automatically gets |
| 22 |
|
relinked by libtool. The documentation has been turned into a man page, so |
| 23 |
|
there are now .1, .txt, and .html versions in /doc. |
| 24 |
|
|
| 25 |
|
5. Upgrades to pcregrep: |
| 26 |
|
(i) Added long-form option names like gnu grep. |
| 27 |
|
(ii) Added --help to list all options with an explanatory phrase. |
| 28 |
|
(iii) Added -r, --recursive to recurse into sub-directories. |
| 29 |
|
(iv) Added -f, --file to read patterns from a file. |
| 30 |
|
|
| 31 |
|
6. pcre_exec() was referring to its "code" argument before testing that |
| 32 |
|
argument for NULL (and giving an error if it was NULL). |
| 33 |
|
|
| 34 |
|
7. Upgraded Makefile.in to allow for compiling in a different directory from |
| 35 |
|
the source directory. |
| 36 |
|
|
| 37 |
|
8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the |
| 38 |
|
options bits, the pointer it was passed was to an int instead of to an unsigned |
| 39 |
|
long int. This mattered only on 64-bit systems. |
| 40 |
|
|
| 41 |
|
9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is |
| 42 |
|
generated) instead of pcre.in, which it its source. Also made the same change |
| 43 |
|
in several of the .c files. |
| 44 |
|
|
| 45 |
|
10. A new release of gcc defines printf() as a macro, which broke pcretest |
| 46 |
|
because it had an ifdef in the middle of a string argument for printf(). Fixed |
| 47 |
|
by using separate calls to printf(). |
| 48 |
|
|
| 49 |
|
11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure |
| 50 |
|
script, to force use of CR or LF instead of \n in the source. On non-Unix |
| 51 |
|
systems, the value can be set in config.h. |
| 52 |
|
|
| 53 |
|
12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an |
| 54 |
|
absolute limit. Changed the text of the error message to make this clear, and |
| 55 |
|
likewise updated the man page. |
| 56 |
|
|
| 57 |
|
13. The limit of 99 on the number of capturing subpatterns has been removed. |
| 58 |
|
The new limit is 65535, which I hope will not be a "real" limit. |
| 59 |
|

|
Version 3.4 22-Aug-00 |
| 62 |
|
--------------------- |
| 63 |
|
|
| 64 |
|
1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *. |
| 65 |
|
|
| 66 |
|
2. Diagnose condition (?(0) as an error instead of crashing on matching. |
| 67 |
