gfxprim.git ("A simple 2D graphics library with emphasis on correctness and well-defined operation.")
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 gfxprim.git.
The branch, master has been updated
discards 6d6139b6ed2cf86b481229d1e5234aecb186b81a (commit)
via 017a24fe557af8dfd0f3b98796ef439db5246a84 (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 (6d6139b6ed2cf86b481229d1e5234aecb186b81a)
N -- N -- N (017a24fe557af8dfd0f3b98796ef439db5246a84)
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.
