Subject: dictionaries-common: Randomness in emacsen-ispell-dicts.el

Date: Fri, 26 Nov 2021 23:47:04 +0100

Package: dictionaries-common
Version: 1.28.12
Severity: wishlist
User: reproducible-builds@lists.alioth.debian.org
Usertags: randomness
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

Hello maintainers of dictionaries-common,

While working on the “reproducible builds” effort [1], I have noticed
that the content of the file '/var/cache/dictionaries-common/emacsen-ispell-
dicts.el' is changing randomly.

In the section 'debian-hunspell-equivs-alist', the value for the 'ca' key can
toggle between 'ca' and 'catala8'. Because Perl does not have a reproducible
order in a foreach statement (unless the keyword sort is used), it will be
rather random which value for the key 'ca' will be set last. With the
environment variable PERL_HASH_SEED [2] I've been able to generate a
reproducible test case.

I'm unsure what would be the correct value. If you can tell me the desired
behaviour, I will provide a patch.

Steps to reproduce:
* Install a minimal Debian bookworm (a live image will work fine)
* Ensure that no aspell, hunspell or ispell is present
* Install 'hunspell-ca'
* Run either of the following commands:
** PERL_HASH_SEED=1 update-dictcommon-hunspell
** PERL_HASH_SEED=2 update-dictcommon-hunspell
* Look at the content of the file '/var/cache/dictionaries-common/emacsen-
ispell-dicts.el'

With kind regards,
Roland Clobus

thanks

Hello Agustin Martin Domingo,

thank you for responding so quickly.

Unfortunately, this issue is still present in 1.28.13...

Here are the commands that I've used to reproduce the case (using 
hunspell-ca):

PERL_HASH_SEED=1 update-dictcommon-hunspell
grep "setq debian-hunspell-equivs-alist" -A 1 -B0 
/var/cache/dictionaries-common/emacsen-ispell-dicts.el

-> output: ("ca" "catala8")

PERL_HASH_SEED=2 update-dictcommon-hunspell
grep "setq debian-hunspell-equivs-alist" -A 1 -B0 
/var/cache/dictionaries-common/emacsen-ispell-dicts.el

-> output: ("ca" "ca")

With kind regards,
Roland Clobus
