Abstract

Application Programming Interfaces (APIs) can get deprecated over time, to indicate that they are obsolete, dangerous, and/or to be eliminated in future versions. This thesis ad- dresses two problems involving API deprecation. API deprecation has not been systematically studied so far. We empirically study how API deprecation has been used in 26 open source Java systems. We find that API dep- recation seems to be underused and not enough information is provided to help users via deprecation messages. More than 40% of all deprecated APIs were removed, most of which were removed during transitions to major releases. A developer may waste valuable time consulting code examples on the web containing deprecated API usages. A version sensitive framework was proposed to detect deprecated API usages in code examples on the web and a prototype tool based on this framework was implemented. Our evaluation of this tool shows that it works fairly well.

The University of Calgary, located in the heart of Southern Alberta, both acknowledges and pays tribute to the traditional territories of the peoples of Treaty 7, which include the Blackfoot Confederacy (comprised of the Siksika, the Piikani, and the Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including Chiniki, Bearspaw, and Goodstoney First Nations). The City of Calgary is also home to the Métis Nation of Alberta (Districts 5 and 6).

The University of Calgary is situated on land Northwest of where the Bow River meets the Elbow River, a site traditionally known as Moh’kins’tsis to the Blackfoot, Wîchîspa to the Stoney Nakoda, and Guts’ists’i to the Tsuut’ina. On this land and in this place we strive to learn together, walk together, and grow together “in a good way.”
