Methods, systems, and computer program products may provide pre-merge conflict avoidance in a revision-control system. A pre-merge conflict avoidance method may include identifying by a computer system a portion of interest of a revision-controlled base source code stored in a source-code repository, the base source code being developed by a plurality of developers. The computer system may determine whether at least one of the plurality of developers has made a change to a portion of a first copy of the base source code corresponding to the portion of interest prior to commitment of the first copy of the base source code to the source-code repository. In response to a determination that the at least one developer has made a change to the portion of interest, a notification may be produced about the change to the portion of interest by the at least one developer.
