Version 1.06 23-Jan-98 |
| 6 |
|
---------------------- |
| 7 |
|
|
| 8 |
|
1. Added Markus Oberhumer's little patches for C++. |
| 9 |
|
|
| 10 |
|
2. Literal strings longer than 255 characters were broken. |
| 11 |
|
|
| 12 |
|

|
Version 1.05 23-Dec-97 |
| 14 |
|
---------------------- |
| 15 |
|
|
| 16 |
|
1. Negated character classes containing more than one character were failing if |
| 17 |
|
PCRE_CASELESS was set at run time. |
| 18 |

Version 1.04 19-Dec-97 |
| 21 |
|
---------------------- |
| 22 |
|
|
| 23 |
|
1. Corrected the man page, where some "const" qualifiers had been omitted. |
| 24 |
|
|
| 25 |
|
2. Made debugging output print "{0,xxx}" instead of just "{,xxx}" to agree with |
| 26 |
|
input syntax. |
| 27 |
|
|
| 28 |
|
3. Fixed memory leak which occurred when a regex with back references was |
| 29 |
|
matched with an offsets vector that wasn't big enough. The temporary memory |
| 30 |
|
that is used in this case wasn't being freed if the match failed. |
| 31 |
|
|
| 32 |
|
4. Tidied pcretest to ensure it frees memory that it gets. |
| 33 |
|
|
| 34 |
|
5. Temporary memory was being obtained in the case where the passed offsets |
| 35 |
|
vector was exactly big enough. |
| 36 |
|
|
| 37 |
|
6. Corrected definition of offsetof() from change 5 below. |
| 38 |
|
|
| 39 |
|
7. I had screwed up change 6 below and broken the rules for the use of |
| 40 |
|
setjmp(). Now fixed. |
| 41 |
|
|
| 42 |
|
|

|
Version 1.03 18-Dec-97 |
| 44 |
|
---------------------- |
| 45 |
|
|
| 46 |
|
1. A erroneous regex with a missing opening parenthesis was correctly |
| 47 |
|
diagnosed, but PCRE attempted to access brastack[-1], which could cause crashes |
| 48 |
|
on some systems. |
| 49 |
|
|
| 50 |
|
2. Replaced offsetof(real_pcre, code) by offsetof(real_pcre, code[0]) because |
| 51 |
|
it was reported that one broken compiler failed on the former because "code" is |
| 52 |
|
also an independent variable. |
| 53 |
|
|
| 54 |
|
3. The erroneous regex a[]b caused an array overrun reference. |
| 55 |
|
|
| 56 |
|
4. A regex ending with a one-character negative class (e.g. /[^k]$/) did not |
| 57 |
|
fail on data ending with that character. (It was going on too far, and checking |
| 58 |
|
the next character, typically a binary zero.) This was specific to the |
| 59 |
|
optimized code for single-character negative classes. |
| 60 |
|
|
| 61 |
|
5. Added a contributed patch from the TIN world which does the following: |
| 62 |
|
|
| 63 |
|
+ Add an undef for memmove, in case the the system defines a macro for it. |
| 64 |
|
|
| 65 |
|
+ Add a definition of offsetof(), in case there isn't one. (I don't know |
| 66 |
|
the reason behind this - offsetof() is part of the ANSI standard - but |
| 67 |
|
it does no harm). |
| 68 |
|
|
| 69 |
|
+ Reduce the ifdef's in pcre.c using macro DPRINTF, thereby eliminating |
| 70 |
|
most of the places where whitespace preceded '#'. I have given up and |
| 71 |
|
allowed the remaining 2 cases to be at the margin. |
| 72 |
|
|
| 73 |
|
+ Rename some variables in pcre to eliminate shadowing. This seems very |
| 74 |
|
pedantic, but does no harm, of course. |
| 75 |
|
|
| 76 |
|
6. Moved the call to setjmp() into its own function, to get rid of warnings |
| 77 |
|
from gcc -Wall, and avoided calling it at all unless PCRE_EXTRA is used. |
| 78 |
|
|
| 79 |
|
7. Constructs such as \d{8,} were compiling into the equivalent of |
| 80 |
|
\d{8}\d{0,65527} instead of \d{8}\d* which didn't make much difference to the |
| 81 |
|
outcome, but in this particular case used more store than had been allocated, |
| 82 |
|
which caused the bug to be discovered because it threw up an internal error. |
| 83 |
|
|
| 84 |
|
8. The debugging code in both pcre and pcretest for outputting the compiled |
| 85 |
|
form of a regex was going wrong in the case of back references followed by |
| 86 |
|
curly-bracketed repeats. |
| 87 |
|
|

Version 1.02 12-Dec-97 |
| 90 |
|
---------------------- |
| 91 |
|
|
| 92 |
|
1. Typos in pcre.3 and comments in the source fixed. |
| 93 |
|
|
| 94 |
|
2. Applied a contributed patch to get rid of places where it used to remove |
| 95 |
|
'const' from variables, and fixed some signed/unsigned and uninitialized |
| 96 |
|
variable warnings. |
| 97 |
|
|
| 98 |
|
3. Added the "runtest" target to Makefile. |
| 99 |
|
|
| 100 |
|
4. Set default compiler flag to -O2 rather than just -O. |
