Autor popul\u00e1rn\u00ed Ruby knihovny mimemagic, kter\u00e1 m\u00e1 v\u00edce ne\u017e 100 milion\u016f sta\u017een\u00ed, byl nucen zm\u011bnit licenci z MIT na GPLv2 kv\u016fli odhalen\u00ed poru\u0161en\u00ed licence GPLv2 v projektu. Na RubyGems byly ponech\u00e1ny pouze verze 0.3.6 a 0.4.0, dod\u00e1van\u00e9 pod GPL, a v\u0161echny star\u00e9 vyd\u00e1n\u00ed pod licenc\u00ed MIT byly odstran\u011bny. Nav\u00edc byla v\u00fdvojov\u00e1 \u010dinnost na mimemagic zastavena a repozit\u00e1\u0159 na GitHubu byl p\u0159eveden do archiva\u010dn\u00edho stavu. <\/p>\n

Tato opat\u0159en\u00ed vedla k poru\u0161en\u00ed mo\u017enosti sestavov\u00e1n\u00ed projekt\u016f, kter\u00e9 pou\u017e\u00edvaj\u00ed mimemagic jako z\u00e1vislost a jsou dod\u00e1v\u00e1ny pod licencemi, kter\u00e9 nejsou kompatibiln\u00ed s GPLv2. P\u0159i pou\u017eit\u00ed nov\u00e9 verze mimemagic jsou v\u00fdvoj\u00e1\u0159i jin\u00fdch projekt\u016f, v\u010detn\u011b propriet\u00e1rn\u00edch (licence MIT to umo\u017e\u0148uje), povinni p\u0159ev\u00e9st sv\u016fj k\u00f3d na licenci GPL. Probl\u00e9m se zhor\u0161il t\u00edm, \u017ee star\u00e9 verze pod licenc\u00ed MIT p\u0159estaly b\u00fdt dostupn\u00e9 na RubyGems.org. Pokud nen\u00ed v sestav\u011b zahrnuto serveru<\/a> ke\u0161ov\u00e1n\u00ed bal\u00ed\u010dk\u016f, pokus o sestaven\u00ed projekt\u016f se star\u0161\u00edmi verzemi mimemagic povede k chyb\u011b. <\/p>\n

Pod tlakem se ocitl tak\u00e9 framework Ruby on Rails, kter\u00fd mezi sv\u00fdmi z\u00e1vislostmi zahrnuje mimemagic. Ruby on Rails je distribuov\u00e1n pod licenc\u00ed MIT a nem\u016f\u017ee obsahovat komponenty pod licenc\u00ed GPL. Probl\u00e9m nabral glob\u00e1ln\u00ed rozm\u011br \u2014 pokud p\u0159\u00edmo zm\u011bna zas\u00e1hla 172 bal\u00ed\u010dk\u016f, pak s ohledem na z\u00e1vislosti utrp\u011blo v\u00edce ne\u017e 577 tis\u00edc repozit\u00e1\u0159\u016f. <\/p>\n

Poru\u0161en\u00ed licence GPL v projektu mimemagic souvis\u00ed s dod\u00e1n\u00edm souboru freedesktop.org.xml v k\u00f3du, kter\u00fd je kopi\u00ed datab\u00e1ze MIME typ\u016f z knihovny shared-mime-info. Uveden\u00fd soubor je \u0161\u00ed\u0159en pod licenc\u00ed GPLv2, zat\u00edmco samotn\u00e1 knihovna shared-mime-info je pod licenc\u00ed ISC, kter\u00e1 je kompatibiln\u00ed s GPL. Zdrojov\u00e9 k\u00f3dy mimemagic byly dod\u00e1v\u00e1ny pod licenc\u00ed MIT a dod\u00e1n\u00ed komponent\u016f pod licenc\u00ed GPLv2 vy\u017eaduje \u0161\u00ed\u0159en\u00ed odvozen\u00e9ho produktu pod licenc\u00ed, kter\u00e1 je kompatibiln\u00ed s GPLv2. Doprovodn\u00fd shared-mime-info na to upozornil a autor mimemagic souhlasil s po\u017eadavkem na zm\u011bnu licence. <\/p>\n

V\u00fdstupem by bylo prov\u00e9st anal\u00fdzu XML souboru za b\u011bhu, bez dod\u00e1n\u00ed freedesktop.org.xml sou\u010d\u00e1st\u00ed knihovny, ale doprovodn\u00fd mimemagic zmrazil repozit\u00e1\u0159 projektu, tak\u017ee tuto pr\u00e1ci mus\u00ed nal\u00e9hav\u011b prov\u00e9st n\u011bkdo jin\u00fd. Mo\u017en\u00e1, pokud autor mimemagicu nebude cht\u00edt vr\u00e1tit sv\u016fj projekt do provozu (zat\u00edm odm\u00edt\u00e1), bude pot\u0159eba vytvo\u0159it fork mimemagicu a nahradit z\u00e1vislost ve v\u0161ech souvisej\u00edc\u00edch projektech. Jako mo\u017enost se tak\u00e9 zva\u017euje p\u0159echod projekt\u016f z\u00e1visl\u00fdch na mimemagic na knihovnu libmagic.
