*libs/output.bash ;) This seems to be a regression in bash-4.2_p24. The problem occurs if the string contains UTF-8 characters and if the extglob shell option is set:
$ LC_ALL=en_US.UTF-8
$ shopt -s extglob
First try with ASCII only, works as expected:
$ text="aaabbb"
$ echo "${text} ${text//?aa} ${text//\aaa}"
aaabbb bbb bbb
But it fails with UTF-8:
$ text="aaaäöü"
$ echo "${text} ${text//?aa} ${text//\aaa}"
aaaäöü aaaäöü aaaäöü
Without extglob, it appears to work properly again:
$ shopt -u extglob
$ echo "${text} ${text//?aa} ${text//\aaa}"
aaaäöü äöü äöü
I don't see the problem with bash-4.1_p11.
Reassigning to base-system.
moved upstream then as 4.1 works but 4.2 fails Patch available (2nd answer), so what we prefer to do now? Waiting for release of new version in upstream or add a patch? ;) i'm going to wait to see what Chet says Chet OK-ed it, so i've added it to 4.2_p24-r1 |
I've tried to add localized news to my overlay and found a bug in news title highlighting in cases when it is UTF-8 in title. Example of bug appearance: % echo ${LC_ALL} ru_RU.UTF-8 % echo ${LANG} ru_RU.UTF-8 % head -n1 2012-04-21-remaking-of-zen-sources.ru.txt Title: Обновление ебилда на ZEN % eselect news read 8 | head -n2 2012-04-21-remaking-of-zen-sources Title %%%HI%%%Обновление ебилда на ZEN%%%RE%%% % export LC_ALL=C % head -n1 2012-04-21-remaking-of-zen-sources.en.txt Title: Remaking of ZEN-sources ebuild % eselect news read 8 | head -n2 2012-04-21-remaking-of-zen-sources Title Remaking of ZEN-sources ebuild Also, I tried to find the bug and I think, that bug is in bash's replacing in apply_text_highlights funtion in /usr/share/eselect/lib/soutput.bash when it replace text in "text" variable. Reproducible: Always
