News about PCRE releases
------------------------
Release 8.34 15-December-2013
-----------------------------
As well as fixing the inevitable bugs, performance has been improved by
refactoring and extending the amount of "auto-possessification" that PCRE does.
Other notable changes:
. Implemented PCRE_INFO_MATCH_EMPTY, which yields 1 if the pattern can match
an empty string. If it can, pcretest shows this in its information output.
. A back reference to a named subpattern when there is more than one of the
same name now checks them in the order in which they appear in the pattern.
The first one that is set is used for the reference. Previously only the
first one was inspected. This change makes PCRE more compatible with Perl.
. Unicode character properties were updated from Unicode 6.3.0.
. The character VT has been added to the set of characters that match \s and
are generally treated as white space, following this same change in Perl
5.18. There is now no difference between "Perl space" and "POSIX space".
. Perl has changed its handling of \8 and \9. If there is no previously
encountered capturing group of those numbers, they are treated as the
literal characters 8 and 9 instead of a binary zero followed by the
literals. PCRE now does the same.
. Following Perl, added \o{} to specify codepoints in octal, making it
possible to specify values greater than 0777 and also making them
unambiguous.
. In UCP mode, \s was not matching two of the characters that Perl matches,
namely NEL (U+0085) and MONGOLIAN VOWEL SEPARATOR (U+180E), though they
were matched by \h.
. Add JIT support for the 64 bit TileGX architecture.
. Upgraded the handling of the POSIX classes [:graph:], [:print:], and
[:punct:] when PCRE_UCP is set so as to include the same characters as Perl
does in Unicode mode.
. Perl no longer allows group names to start with digits, so I have made this
change also in PCRE.
. Added support for [[:<:]] and [[:>:]] as used in the BSD POSIX library to
mean "start of word" and "end of word", respectively, as a transition aid.

At compile time, PCRE "auto-possessifies" repeated items when it knows that
what follows cannot be part of the repeat. For example, a+[bc] is compiled as
if it were a++[bc]. The <b>pcretest</b> output when this pattern is anchored and
then applied with automatic callouts to the string "aaaa" is:
<pre>
---&#62;aaaa
+0 ^ ^
+1 ^ a+
+3 ^ ^ [bc]
No match
</pre>
This indicates that when matching [bc] fails, there is no backtracking into a+
and therefore the callouts that would be taken for the backtracks do not occur.
You can disable the auto-possessify feature by passing PCRE_NO_AUTO_POSSESS
to <b>pcre_compile()</b>, or starting the pattern with (*NO_AUTO_POSSESS). If
this is done in <b>pcretest</b> (using the /O qualifier), the output changes to
this:
<pre>
---&#62;aaaa
+0 ^ ^
+1 ^ a+
+3 ^ ^ [bc]
+3 ^ ^ [bc]
+3 ^ ^ [bc]
+3 ^^ [bc]
No match
</pre>
This time, when matching [bc] fails, the matcher backtracks into a+ and tries
again, repeatedly, until a+ itself fails.

PCRE's "auto-possessification" optimization usually applies to character
repeats at the end of a pattern (as well as internally). For example, the
pattern "a\d+" is compiled as if it were "a\d++" because there is no point
even considering the possibility of backtracking into the repeated digits. For
DFA matching, this means that only one possible match is found. If you really
do want multiple matches in such cases, either use an ungreedy repeat
("a\d+?") or set the PCRE_NO_AUTO_POSSESS option when compiling.

That means that, for an unanchored pattern, if a continued match fails, it is
not possible to try again at a new starting point. All this facility is capable
of doing is continuing with the previous match attempt. In the previous
example, if the second set of data is "ug23" the result is no match, even
though there would be a match for "aug23" if the entire string were given at
once. Depending on the application, this may or may not be what you want.
The only way to allow for starting again at the next character is to retain the
matched part of the subject and try a new complete match.

Locking out certain modifiers
</b><br>
<P>
PCRE can be compiled with or without support for certain features such as
UTF-8/16/32 or Unicode properties. Accordingly, the standard tests are split up
into a number of different files that are selected for running depending on
which features are available. When updating the tests, it is all too easy to
put a new test into the wrong file by mistake; for example, to put a test that
requires UTF support into a file that is used when it is not available. To help
detect such mistakes as early as possible, there is a facility for locking out
specific modifiers. If an input line for <b>pcretest</b> starts with the string
"&#60; forbid " the following sequence of characters is taken as a list of
forbidden modifiers. For example, in the test files that must not use UTF or
Unicode property support, this line appears:
<pre>
&#60; forbid 8W
</pre>
This locks out the /8 and /W modifiers. An immediate error is given if they are
subsequently encountered. If the character string contains &#60; but not &#62;, all the
multi-character modifiers that begin with &#60; are locked out. Otherwise, such
modifiers must be explicitly listed, for example:
<pre>
&#60; forbid &#60;JS&#62;&#60;cr&#62;
</pre>
There must be a single space between &#60; and "forbid" for this feature to be
recognised. If there is not, the line is interpreted either as a request to
re-load a pre-compiled pattern (see "SAVING AND RELOADING COMPILED PATTERNS"
below) or, if there is a another &#60; character, as a pattern that uses &#60; as its
delimiter.

character of the subject. The algorithm does not automatically move on to find
matches that start at later positions.
.P
PCRE's "auto-possessification" optimization usually applies to character
repeats at the end of a pattern (as well as internally). For example, the
pattern "a\ed+" is compiled as if it were "a\ed++" because there is no point
even considering the possibility of backtracking into the repeated digits. For
DFA matching, this means that only one possible match is found. If you really
do want multiple matches in such cases, either use an ungreedy repeat
("a\ed+?") or set the PCRE_NO_AUTO_POSSESS option when compiling.
.P
There are a number of features of PCRE regular expressions that are not
supported by the alternative matching algorithm. They are as follows:
