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 unstable/scribo has been updated discards 275b60f548221f4df2457804b2211065d45fec13 (commit) via 2fe026c16ad4d9df4266c16993684576ba8b495d (commit) via f92264244ca22751936f2f909ab911a2e6d9753f (commit) via 81bdc8aae8645f38551682ac4ac8e2657cc7b3d9 (commit) via b375ab3e82b52e4a07a4590c02272c718f8ffa6c (commit) via 4938c8d839f9d4994cf577d8dd57906636d9d25d (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 (275b60f548221f4df2457804b2211065d45fec13) \ N -- N -- N (2fe026c16ad4d9df4266c16993684576ba8b495d) 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 ----------------------------------------------------------------- 2fe026c scribo/binarization/sauvola_ms.hh: Add overloads. f922642 scribo/core/document.hh: Add more assertions. 81bdc8a scribo/primitive/link/with_single_left_link_dmax_ratio_aligned.hh: Fix an invalid forward declaration. b375ab3 doc/Makefile.am: Fix EXTRA_DIST. 4938c8d Small fixes. ----------------------------------------------------------------------- Summary of changes: milena/ChangeLog | 4 ++ milena/doc/Makefile.am | 25 ++++++--- scribo/ChangeLog | 16 ++++++- scribo/scribo/binarization/sauvola_ms.hh | 19 +++++++ scribo/scribo/core/document.hh | 53 +++++++++++++++++++- .../with_single_left_link_dmax_ratio_aligned.hh | 11 ++-- 6 files changed, 112 insertions(+), 16 deletions(-) hooks/post-receive -- Olena, a generic and efficient image processing platform
