I've been working on a patch for ITK that incorporates the double-conversion library from Google.
http://review.source.kitware.com/#/c/9983/ Part of the process of doing this addition is to define a procedure to incorporate new changes from the upstream Google repository. Prompted by Brad King, I came up with a methodology that would do this in an orderly fashion. I documented this in Modules/ThirdParty/DoubleConversion/README-ITK.cmake. Brad King pointed out, correctly, that this method would not properly capture the change history with respect to the Google repository. He pointed me to the procedure used for VXL. I found that his procedure was beyond my understanding of git, but what I believe is happening is this: Create a branch in the ITK repository in which the unmodified VXL source is checked in. The ITK-local changes to VXL, if any are based off the head of that branch. When a new version of VXL is incorporated, the new version is checked in at the head of that branch. Then the changes are merged into ITK proper. There are some things about this process I'm not sure I understand: 1. Is this compatible with the Gerrit topic paradigm? It seems as though the gerrit-merge, which merges a monolithic patch branch into ITK proper, doesn't allow for keeping the update branches around. It isn't clear to me how the merge branches are maintained. It looks as though the intermediate checkin branches go away after the merge, when the new source is pushed back to the ITK master repository. But I'm not sure? 2. Is there a simpler way to go about this? I keep trying to think of how I'd go about this and keep hitting the wall on my git knowledge. Brad's method works for him, I'm sure, but when I try and follow his instructions I end up with a tree that's a big mess, and not what we want. -- Kent Williams [email protected] ________________________________ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
