branch swilena updated: last-svn-commit-176-g29c2a51

by git＠lrde.epita.fr

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "Olena, a generic and efficient image processing platform". The branch swilena has been updated discards 19fd7f5144d94a4a8c5afb11ff3094400023783e (commit) via 29c2a518a4da145319fef5d89443cb17f20112f7 (commit) This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (19fd7f5144d94a4a8c5afb11ff3094400023783e) \ N -- N -- N (29c2a518a4da145319fef5d89443cb17f20112f7) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- 29c2a51 Fix the generation of the sps scripts. ----------------------------------------------------------------------- Summary of changes: swilena/ChangeLog | 3 ++- swilena/python/Makefile.am | 1 + 2 files changed, 3 insertions(+), 1 deletions(-) hooks/post-receive -- Olena, a generic and efficient image processing platform
