La conversion du rapport technique n°0307 plante. En gros, il y a un merge dans ce rapport: la version 0.7 est fille de 0.3 (pas de 0.6) et entre les deux, un répertoire a disparu avec son contenu, mais le contenu réapparaît ailleurs dans 0.7. prcs2svn commence par effacer l'ancien répertoire, puis tente de déplacer son contenu au nouvel emplacement. La partie coupable de prcs2svn se trouve en fin de la méthode merge: ,---- | # Fix tc's bug | if prcs_merge_parent != prcsProject.prj.merge_parents[-1]: | self.svn.changes_apply_files_directories_delete(diffs) `----- Étant donné le caractère douteux de ce code, et compte tenu du commentaire qui le précède de surcroît, je suggère que ces lignes soient optionnelles, et désactivées par défaut. -- Didier Verna, didier(a)lrde.epita.fr, http://www.lrde.epita.fr/~didier EPITA / LRDE, 14-16 rue Voltaire Tel.+33 (1) 44 08 01 85 94276 Le Kremlin-Bicêtre, France Fax.+33 (1) 53 14 59 22 didier(a)xemacs.org

LT 92: Rationalize the invocation of traditional Unix commands

by Akim Demaille

Index: ChangeLog from Akim Demaille <akim(a)epita.fr> Rationalize the invocation of traditional Unix commands. It should be possible to redo what prcs2svn did by grepping "prcs2svn $". The test suite fails, I have no idea why... * prcs2svn/prcs2svn.py (error): Fix >> use. (trace): New. (xsystem, xtee): Use it. (xcopy, xrm, xpopen, xcat, xchdir, xmkdir, xmove): New. Use them where ever their low level implementation was used. * prcs2svn/prcs2svn.py (Svn.changes_apply_files_rename): Don't rm files you just mv'ed.

Mauvais style de programmation

Au minimum, ces méthodes devraient s'appeler maybe_... 2/ Ça fait des appels de fonction qui retournent tout de suite ce qui n'est pas beau (bien sûr je pinaille, mais c'est au niveau des principes). 3/ D'autant que le test est fait sur quelque chose de global (infos). 4/ Donc il est bien plus propre de sortir le test de la fonction elle-même. -- Didier Verna, didier(a)lrde.epita.fr, http://www.lrde.epita.fr/~didier EPITA / LRDE, 14-16 rue Voltaire Tel.+33 (1) 44 08 01 85 94276 Le Kremlin-Bicêtre, France Fax.+33 (1) 53 14 59 22 didier(a)xemacs.org
