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 (303c7ee8a708463abcc24a54d52818310af1c7a3) \ N -- N -- N (357bde878da59be0f237a61b541b55baab3dae79) 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 ----------------------------------------------------------------- 357bde8 NEWS: Add notification for data::stretch_inplace. c54e470 tests/data/stretch.cc: Remove useless include. 6dbc5e1 Regen generated files in Milena. 9a6e78a Add data::stretch_inplace. 1a03222 mln/data/stretch_inplace.hh: Add stretch inplace. ----------------------------------------------------------------------- Summary of changes: ChangeLog | 4 + NEWS | 2 + milena/ChangeLog | 31 +-- milena/mln/binarization/tmms.hh | 139 -------- milena/mln/binarization/tmms_hysteresis.hh | 329 -------------------- milena/mln/canvas/labeling/blobs.hh | 12 +- milena/mln/data/stretch_inplace.hh | 24 +- milena/mln/labeling/all_blobs.hh | 127 -------- milena/mln/labeling/blobs.hh | 52 ++-- milena/mln/labeling/blobs_and_compute.hh | 16 +- milena/mln/labeling/values.hh | 166 ---------- milena/tests/data/Makefile.am | 3 +- milena/tests/data/stretch.cc | 4 +- .../tests/data/{saturate.cc => stretch_inplace.cc} | 25 +- milena/tests/labeling/Makefile.am | 1 - milena/tests/labeling/all_blobs.cc | 63 ---- 16 files changed, 76 insertions(+), 922 deletions(-) delete mode 100644 milena/mln/binarization/tmms.hh delete mode 100644 milena/mln/binarization/tmms_hysteresis.hh delete mode 100644 milena/mln/labeling/all_blobs.hh delete mode 100644 milena/mln/labeling/values.hh copy milena/tests/data/{saturate.cc => stretch_inplace.cc} (76%) delete mode 100644 milena/tests/labeling/all_blobs.cc hooks/post-receive -- Olena, a generic and efficient image processing platform
