Post-commit scripta

[ sEaGhOsT @ 23.09.2009. 18:37 ] @

Nisam siguran da li postujem u pravom forumu (ako sam pogresio prebacite temu o odgovarajuci), ali mislim da je problem koji imam vise vezan za FreeBSD nego za SVN ili Python. Imam post-commit skriptu koja je napisana u Python-u i koja nakon svakog commit-a na SVN update-uje samo promenjene fajlove, dakle ne update-uje ceo repository, skripta savrseno radi na Ubuntu Linux-u, ali kada je stavim na FreeBSD jednostavno odbija saradnju. Ispod je kod, koji kao sto sam vec napomenuo savrseno radi na Ubunut-u distribuciji. Kada u post-commit fajl ubacim bash skriptu za update-ovanje koja update-uje ceo repository, ona radi sasvim normalno, tako da mislim da je problem sa Python-om ili sa system-om. Svaka vrsta pomoci bila bi mi veoma korisna. Mislim da je skripta vrlo korisna i svako kome je potrebno ovako nesto moze slobodno da je koristi i modfikuje po svojim potrebama. Variable koje se nalaze u kodu promenjene su iz sigurnosnih razloga.
