En-têtes de licence dans les fichiers de tests ?
by Roland Levillain 24 Mar '06

24 Mar '06

Faut-il insérer les en-têtes de licence/droit d'auteur dans les fichiers de tests des projets du labo ? Est-ce que ça dépend de la taille du test (en lignes de codes), le cas échéant ? Merci d'avance pour vos réponses !

havm 160: Rename config/ as build-aux/
by Roland Levillain 07 Mar '06

07 Mar '06

This is a hand-made mail after an abortion of Vcs (a fresh install on a machine where my GPG key was missing...). I tried to send this mail using `vcs-svn mail' afterwards, but `mail' looks like an inner method according to Vcs' sources (even if it's mentioned by `vcs-svn help'). Is there any plan to support `mail' as a Vcs user command in the future? https://svn.lrde.epita.fr/svn/havm/trunk Index: ChangeLog from Roland Levillain <roland(a)lrde.epita.fr> Rename config/ as build-aux/. * configure.ac: Bump to 0.23a.

>>> "Nicolas" == Nicolas Pouillard <nicolas.pouillard(a)gmail.com> writes: > - The locale LC_ALL=C has stranges behaviors. Err... This statement is even stranger: portable scripts set LC_ALL=C and I never experienced problems in such a context. Alternatively, you may unset it. But remember to cover the whole set of locale related envvars.

Vcs and locales
by Roland Levillain 06 Mar '06

06 Mar '06

I set up a Vcs install in another machine today, and I ran into a new problem : ~/src/nolimips % vcs-svn status vcs: error: command: svn status -- vcs: error: exit: 1 vcs: error: stderr: svn: error: cannot set LC_ALL locale vcs: error: stderr: svn: error: environment variable LC_ALL is en_US vcs: error: stderr: svn: error: please check that your locale name is correct vcs: error: command failed However, after the installation of fresh new en_US locale (thank you, dpkg-reconfigure!), the error vanished. Does this means that Vcs has a dependency on a en_US locale? (`vcs --check' doesn't mention it, BTW.)
