tag 851771 + patch thanks Hello,
TT-RSS is an important application for FreedomBox and it continues to use php-gettext library. TT-RSS is currently not available for testing. It would be nice to have it back. To address this, I have implemented a parser for the plurals expressions instead of using the eval() method as discussed in the upstream bug as solution. This patch is under the same license as php-gettext (GPLv2 or higher). - A simple operator-precedence parser that prioritizes simplicity and readability. Avoid using eval() for evaluating plural expressions. - Fixes CVE-2016-6175. - Fixes upstream bug https://bugs.launchpad.net/php-gettext/+bug/1606184 - Fixes Debian bug https://bugs.debian.org/851771 - Grammar for parsing code is same as the grammar for GNU gettext library: http://git.savannah.gnu.org/cgit/gettext.git/tree/gettext-runtime/intl/plural.y - Extensive tests for various locales with help from Unicode's plurals rules. Tests for invalid syntax and expression parsing. This patch has been submitted upstream at https://bugs.launchpad.net/php-gettext/+bug/1606184 . Please consider applying the patch in Debian if the upstream doesn't do so shortly. Thanks, -- Sunil
From ebe92d9d97dc21b82225c6a7977adf87dd00f799 Mon Sep 17 00:00:00 2001 From: Sunil Mohan Adapa <su...@medhas.org> Date: Thu, 11 Jun 2020 15:00:34 -0700 Subject: [PATCH] Iterate user table in a sorted way, fix tests with latest glib This is primarily to help test cases which assume that the adopted algorithm prioritizes the users in the exact reverse order they appear in the test cases (and get inserted into the session in reverse order). With older glib version, the five users being inserted happened to return the order expected by the tests. With latest glib, due to a minor tweak in hashing strategy, the insertion leads to unsorted list leading to failed tests. In addition, GHashTable makes no guarantees about the stability of items when iterating multiple times. Since the algorithm is sensitive to order of users, it is best to return users in an order that is consistent over multiple calls and stable over insert/remove operations. This patch maintains a sorted list of user ids and uses it for iteration. Closes: #22.
