- | ===== Setting Up an Archive | + | Subversion vám poskytuje různé možnosti, kde založit tzv. **repozitář** (tedy archív verzí vašeho projektu), a různé možnosti, jak k němu přistupovat. **Lokální repozitář** vám stačí, používáte-li Subversion pro archivaci projektu, na kterém pracujete pouze vy, případně i další členové ÚFALu, ale všem vám stačí přistupovat k repozitáři z terminálu či skriptů běžících na linuxových počítačích na ÚFALu. Lokální repozitář je prostě podstrom adresářové struktury na síťových discích (konkrétně v ''/ |

+ | |||
+ | Toto je Milanovo e-mailové shrnutí z 26.9.2007. Týká se konfigurace serverových repozitářů na serveru svn.ms.mff.cuni.cz. | ||
+ | |||
+ | Mili kolegove, | ||
+ | po diskusi s Ondrou Bojarem a drobnem vylepseni naseho serveru svn jeste jednou sepisuji co je potreba si projit a nastavit pri konfiguraci noveho projektu: | ||
+ | |||
+ | - nalogujete se na svn.ufal.ms.mff.cuni.cz (= svn.ms.mff.cuni.cz) (ucty byly preneseny z ufal.mff.cuni.cz) | ||
+ | - pro vytvoreni projektu pouzijete skript (kteremu date jeste jmeno projektu):< | ||
+ | - pak se rozhodnete kterymi cestami budete s projektem pracovat - nejlepsi je asi nakonfigurovat vsechny (viz. nize) - tedy svn, webovy pristup do svn a Trac (take webovy). Vsude jsou prednastaveny nejake zakladni ucty, ale nejlepsi je tyto veci upravit podle vlastnich potreb. Napriklad nemusite chtit, aby ufal/ | ||

+ | Toto rozhraní je užíváno SVN klienty, kteří dostanou repository udanou ve tvaru '' | ||
+ | < | ||
+ | |||
+ | Co se tyce svn weboveho rozhrani, tak ten modul ma nasledujici konfiguraky (viz. / | ||
+ | * uzivatele: '' | ||
+ | * jejich opravneni: '' | ||
+ | O zbytek se stara webovy modul subversion - ja mu jen rikam tohle. | ||
+ | |||
+ | Konfiguraky jsou globalni, tj. pro vsechny projekty spolecne. | ||

+ | |||
+ | Trac - pouziva take overovani vuci: | ||

+ | Takto spustíte konfigurační skript pro Trac vašeho projektu: | ||
+ | trac-admin / | ||
+ | |||

+ | ==== Přidávání vlastních uživatelů pro webové přístupy (SVN i Trac) ==== | ||
+ | |||
+ | Vlastni uzivatele pro webove pristupy pridate do centralniho souboru webovych hesel v ''/ | ||
+ | |||
+ | htpasswd -bs / | ||
