Autor popul\u00e1rnej Ruby kni\u017enice mimemagic, ktor\u00e1 m\u00e1 viac ako 100 mili\u00f3nov stiahnut\u00ed, bol n\u00faten\u00fd zmeni\u0165 licenciu z MIT na GPLv2 kv\u00f4li zisteniu poru\u0161enia licencie GPLv2 v projekte. V RubyGems zostali len verzie 0.3.6 a 0.4.0 dod\u00e1van\u00e9 pod GPL, pri\u010dom v\u0161etky star\u0161ie vydania pod licenciou MIT boli odstr\u00e1nen\u00e9. Navy\u0161e bola v\u00fdvoj mimemagic zastaven\u00e1 a repozit\u00e1r na GitHub bol preveden\u00fd do arch\u00edvneho stavu. <\/p>\n

Tieto kroky sp\u00f4sobili probl\u00e9m so zostavovan\u00edm projektov, ktor\u00e9 pou\u017e\u00edvaj\u00fa mimemagic ako z\u00e1vislos\u0165 a s\u00fa dod\u00e1van\u00e9 pod licenciami, ktor\u00e9 nie s\u00fa kompatibiln\u00e9 s GPLv2. Pri pou\u017e\u00edvan\u00ed novej verzie mimemagic s\u00fa v\u00fdvoj\u00e1ri in\u00fdch projektov, vr\u00e1tane propriet\u00e1rnych (licencia MIT to umo\u017e\u0148uje), n\u00faten\u00ed prelicencova\u0165 svoj k\u00f3d pod GPL. Probl\u00e9m bol zosilnen\u00fd t\u00fdm, \u017ee star\u00e9 verzie pod licenciou MIT prestali by\u0165 dostupn\u00e9 na RubyGems.org. Ak nie je pri zostavovan\u00ed serveri<\/a> zahrnut\u00e9 cachovanie bal\u00edkov, pokus o zostavenie projektov so star\u0161\u00edmi verziami mimemagic bude zlyha\u0165. <\/p>\n

Pod \u00fatok sa dostal aj r\u00e1mec Ruby on Rails, ktor\u00fd na\u010d\u00edtava mimemagic medzi svojimi z\u00e1vislos\u0165ami. Ruby on Rails je dod\u00e1van\u00fd pod licenciou MIT a nem\u00f4\u017ee obsahova\u0165 komponenty pod GPL. Probl\u00e9m nadobudol glob\u00e1lny charakter \u2014 ak priamo zmeny zasiahli 172 bal\u00edkov, tak s oh\u013eadom na z\u00e1vislosti bolo ovplyvnen\u00fdch viac ako 577 tis\u00edc repozit\u00e1rov. <\/p>\n

Poru\u0161enie licencie GPL v projekte mimemagic s\u00favis\u00ed s dodan\u00edm s\u00faboru freedesktop.org.xml v k\u00f3de, ktor\u00fd je k\u00f3piou datab\u00e1zy MIME typov z kni\u017enice shared-mime-info. Uveden\u00fd s\u00fabor sa distribuuje pod licenciou GPLv2, zatia\u013e \u010do sama kni\u017enica shared-mime-info je pod licenciou ISC, kompatibilnou s GPL. Zdrojov\u00e9 k\u00f3dy mimemagic sa dod\u00e1vali pod licenciou MIT, a dodanie komponentov pod licenciou GPLv2 vy\u017eaduje \u0161\u00edrenie odvoden\u00e9ho produktu pod licenciou, ktor\u00e1 je kompatibiln\u00e1 s GPLv2. Sprievodca shared-mime-info na to upozornil a autor mimemagic s\u00fahlasil s po\u017eiadavkou zmeni\u0165 licenciu. <\/p>\n

Rie\u0161en\u00edm by bolo spracovanie XML s\u00faboru za behu, bez dodania freedesktop.org.xml ako s\u00fa\u010dasti kni\u017enice, av\u0161ak sprievodn\u00fd mimemagic zmrazil repozit\u00e1r projektu, preto t\u00fato pr\u00e1cu bude musie\u0165 r\u00fdchlo vykona\u0165 niekto in\u00fd. Mo\u017eno, ak autor mimemagic nebude chcie\u0165 obnovi\u0165 svoj projekt (zatia\u013e sa odmieta), bude potrebn\u00e9 vytvori\u0165 fork mimemagic a nahradi\u0165 z\u00e1vislos\u0165 vo v\u0161etk\u00fdch s\u00favisiacich projektoch. Ako mo\u017enos\u0165 sa tie\u017e zva\u017euje prechod projektov z\u00e1visl\u00fdch na mimemagic na kni\u017enicu libmagic.
