PCRE2 is een herziene implementatie van de originele PCRE-bibliotheek met een incompatibele API en uitgebreide mogelijkheden. De bibliotheek is ontwikkeld door de makers van de mailserver Exim en wordt verspreid onder de BSD-licentie.    <\/p>\n<p>Belangrijkste wijzigingen:  <\/p>\n<ul>\n<li class=\"l\"> De symbolen van de POSIX-functies, zoals regcomp, zijn uit de libpcre2-posix-bibliotheek verwijderd, omdat ze problemen veroorzaakten bij sommige applicaties. De patch pcre2-symbol-clash.patch is in de upstream aangenomen. Ook is de ABI-versie van deze bibliotheek bijgewerkt.\n<li class=\"l\"> Een probleem dat hypothetisch leidde tot dereferencen van een null-pointer is opgelost.\n<li class=\"l\"> Twee fouten bij het verwerken van zeer grote nummers zijn opgelost, waardoor een gedrag ontstond dat niet overeenkomt met de Perl-reguliere expressiemotor. Bijvoorbeeld, de expressie \u2018\/\\214748364\/\u2019 leidde tot een overflow in plaats van het verwerken als een octaal nummer \u2018\\214\u2019 met de volgende tekens \u2018748364\u2019.\n<li class=\"l\"> Het verkeerde gedrag bij het gebruik van de operatie \u2018\\K\u2019 in sjablonen is gecorrigeerd.\n<li class=\"l\"> In JIT is de optimalisatie van herhalingsoperaties voor tekens hersteld.   <\/ul>\n<p>Bron: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=55234\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0412\u044b\u0448\u0435\u043b \u0440\u0435\u043b\u0438\u0437 \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0438 PCRE2 10.37, \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0435\u0439 \u043d\u0430\u0431\u043e\u0440 \u0444\u0443\u043d\u043a\u0446\u0438\u0439 \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 \u0421\u0438 \u0441 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 \u0440\u0435\u0433\u0443\u043b\u044f\u0440\u043d\u044b\u0445 \u0432\u044b\u0440\u0430\u0436\u0435\u043d\u0438\u0439 \u0438 \u0441\u0440\u0435\u0434\u0441\u0442\u0432 \u0441\u043e\u043f\u043e\u0441\u0442\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u0441 \u043e\u0431\u0440\u0430\u0437\u0446\u043e\u043c (pattern matching), \u0431\u043b\u0438\u0437\u043a\u0438\u0445 \u043f\u043e \u0441\u0438\u043d\u0442\u0430\u043a\u0441\u0438\u0441\u0443 \u0438 \u0441\u0435\u043c\u0430\u043d\u0442\u0438\u043a\u0435 \u043a \u0440\u0435\u0433\u0443\u043b\u044f\u0440\u043d\u044b\u043c \u0432\u044b\u0440\u0430\u0436\u0435\u043d\u0438\u044f\u043c \u044f\u0437\u044b\u043a\u0430 Perl 5.
