From 70d585151c03ede999bd2ad5a724243914cb5f54 Mon Sep 17 00:00:00 2001 From: Arjun Shankar <arjun@redhat.com> Date: Tue, 7 Jul 2020 20:31:48 +0200 Subject: [PATCH] Rewrite iconv option parsing [BZ #19519] This commit replaces string manipulation during `iconv_open' and iconv_prog option parsing with a structured, flag based conversion specification. In doing so, it alters the internal `__gconv_open' interface and accordingly adjusts its uses. This change fixes several hangs in the iconv program and therefore includes a new test to exercise iconv_prog options that originally led to these hangs. It also includes a new regression test for option handling in the iconv function. Reviewed-by: Florian Weimer <fweimer@redhat.com> Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org> Reviewed-by: Carlos O'Donell <carlos@redhat.com> (cherry picked from commit 91927b7c76437db860cd86a7714476b56bb39d07) --- From 32965a46ce978f271ec6d3745f951da111c8e74a Mon Sep 17 00:00:00 2001 From: Arjun Shankar <arjun@redhat.com> Date: Fri, 25 Sep 2020 14:47:06 +0200 Subject: [PATCH] intl: Handle translation output codesets with suffixes [BZ #26383] Commit 91927b7c7643 (Rewrite iconv option parsing [BZ #19519]) did not handle cases where the output codeset for translations (via the `gettext' family of functions) might have a caller specified encoding suffix such as TRANSLIT or IGNORE. This led to a regression where translations did not work when the codeset had a suffix. This commit fixes the above issue by parsing any suffixes passed to __dcigettext and adds two new test-cases to intl/tst-codeset.c to verify correct behaviour. The iconv-internal function __gconv_create_spec and the static iconv-internal function gconv_destroy_spec are now visible internally within glibc and used in intl/dcigettext.c.
