Forfatteren af det popul\u00e6re Ruby-bibliotek mimemagic, der har over 100 millioner downloads, var n\u00f8dt til at \u00e6ndre licensen fra MIT til GPLv2 p\u00e5 grund af opdagelsen af en overtr\u00e6delse af GPLv2-licensen i projektet. Kun versionerne 0.3.6 og 0.4.0, der er udgivet under GPL, er tilbageholdt i RubyGems, mens alle tidligere udgivelser under MIT-licensen er blevet fjernet. Desuden er udviklingen af mimemagic stoppet, og repositoryet p\u00e5 GitHub er blevet arkiveret. <\/p>\n

Disse handlinger har f\u00f8rt til forstyrrelser i mulighederne for at bygge projekter, der bruger mimemagic som afh\u00e6ngighed og distribueres under licenser, der er uforenelige med GPLv2. Ved brug af den nye version af mimemagic er udviklere af andre projekter, inklusive propriet\u00e6re (MIT-licensen tillader s\u00e5dan brug), forpligtet til at relicensere deres kode under GPL. Problemet er blevet forv\u00e6rret af, at gamle versioner under MIT-licensen ikke l\u00e6ngere er tilg\u00e6ngelige fra RubyGems.org. Hvis pakke-caching ikke er inkluderet, serveren<\/a> vil et fors\u00f8g p\u00e5 at bygge projekter med tidligere versioner af mimemagic resultere i fejl. <\/p>\n

Frameworket Ruby on Rails er ogs\u00e5 blevet ber\u00f8rt, da det har mimemagic blandt sine afh\u00e6ngigheder. Ruby on Rails distribueres under MIT-licensen og m\u00e5 ikke inkludere komponenter under GPL. Problemet har antaget globale dimensioner \u2014 hvis \u00e6ndringen direkte p\u00e5virkede 172 pakker, s\u00e5 er mere end 577.000 repositories blevet ramt, n\u00e5r man tager afh\u00e6ngighederne i betragtning. <\/p>\n

Overtr\u00e6delsen af GPL-licensen i mimemagic-projektet er relateret til leveringen af filen freedesktop.org.xml i koden, som er en kopi af MIME-type databasen fra biblioteket shared-mime-info. Den n\u00e6vnte fil distribueres under GPLv2-licensen, mens selve biblioteket shared-mime-info er under ISC-licensen, som er kompatibel med GPL. Kildeteksterne til mimemagic blev leveret under MIT-licensen, og levering af komponenter under GPLv2-licensen kr\u00e6ver distribution af det afledte produkt under en licens, der er kompatibel med GPLv2. Den tilknyttede shared-mime-info gjorde opm\u00e6rksom p\u00e5 dette, og forfatteren af mimemagic accepterede kravene om at \u00e6ndre licensen. <\/p>\n

L\u00f8sningen ville v\u00e6re at udf\u00f8re parsing af XML-filen on-the-fly, uden at levere freedesktop.org.xml som en del af biblioteket, men den tilh\u00f8rende mimemagic har fryset projektets repository, s\u00e5 denne opgave m\u00e5 hurtigt udf\u00f8res af nogen anden. M\u00e5ske, hvis forfatteren af mimemagic ikke \u00f8nsker at bringe sit projekt tilbage (indtil videre n\u00e6gter han), vil det kr\u00e6ve oprettelse af en fork af mimemagic og erstatning af afh\u00e6ngigheden i alle relaterede projekter. Som et alternativ overvejes ogs\u00e5 overgangen af projekter afh\u00e6ngig af mimemagic til biblioteket libmagic.
