The content of this blog is my personal opinion only. Although I am an employee - currently of Nvidia, in the past of other companies such as Iagination Technologies, MIPS, Intellectual Ventures, Intel, AMD, Motorola, and Gould - I reveal this only so that the reader may account for any possible bias I may have towards my employer's products. The statements I make here in no way represent my employer's position, nor am I authorized to speak on behalf of my employer. In fact, this posting may not even represent my personal opinion, since occasionally I play devil's advocate.

LOD branches (Lines of Development)

Not sure if this is a Glewism, although Brad Appleton's book undoubtedly similar.

A LOD branch is not like a task branch.  A task brach ideally exists only briefly.

A LOD branch is long lived.  It may be periodically synchronized with other OD branches, and/or the mainline of development.  Bidirectionally synchronized - changes may be pushed and pulled.

For long periods of time a LOD branch may be collapsed - basically part of the main line of development.  But it may be revived as a separate LOD branch.

Examples of LOD branches:

* branches for different platforms, where there is not a single source tree with ifdeffing or other conditionals

* maintenance branches for old major releases

* branches where you are working on a new experimental feature or system
