From b464e51ab32fbf09cf5d9c911a8e26f491ad1f44 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 18 Feb 2025 21:13:46 -0500 Subject: Update to latest Snowball sources. It's been some time since we did this, partly because the upstream snowball project hasn't formally tagged a new release since 2021. The main motivation for doing it now is to absorb a bug fix (their commit e322673a841d9abd69994ae8cd20e191090b6ef4), which prevents a null pointer dereference crash if SN_create_env() gets a malloc failure at just the wrong point. We'll patch the back branches with only that change, but we might as well do the full sync dance on HEAD. Aside from a bunch of mostly-minor tweaks to existing stemmers, this update adds a new stemmer for Estonian. It also removes the existing stemmer for Romanian using ISO-8859-2 encoding. Upstream apparently concluded that ISO-8859-2 doesn't provide an adequate representation of some Romanian characters, and the UTF-8 implementation should be used instead. While at it, update the README's instructions for doing a sync, which have not been adjusted during the addition of meson tooling. Thanks to Maksim Korotkov for discovering the null-pointer bug and submitting the fix to upstream snowball.
