The current semantic patch for COPY_ARRAY transforms memcpy(3) calls on pointers, but Coccinelle distinguishes them from arrays. It already contains three rules to handle the options for sizeof (i.e. source, destination and type), and handling arrays as source and destination would require four times as many rules if we enumerated all cases. We also don't handle array subscripts, and supporting that would increase the number of rules by another factor of four. (An isomorphism telling Coccinelle that "sizeof x[...]" is equivalent to "sizeof *x" would be nice..) Support arrays and array subscripts, but keep the number of rules down by adding normalization steps: First turn array subscripts into derefences, then determine the types of expressions used with sizeof and replace them with these types, and then convert the different possible combinations of arrays and pointers with memcpy(3) to COPY_ARRAY.

Contributed Software Although these pieces are available as part of the official git source tree, they are in somewhat different status. The intention is to keep interesting tools around git here, maybe even experimental ones, to give users an easier access to them, and to give tools wider exposure, so that they can be improved faster. I am not expecting to touch these myself that much. As far as my day-to-day operation is concerned, these subdirectories are owned by their respective primary authors. I am willing to help if users of these components and the contrib/ subtree "owners" have technical/design issues to resolve, but the initiative to fix and/or enhance things _must_ be on the side of the subtree owners. IOW, I won't be actively looking for bugs and rooms for enhancements in them as the git maintainer -- I may only do so just as one of the users when I want to scratch my own itch. If you have patches to things in contrib/ area, the patch should be first sent to the primary author, and then the primary author should ack and forward it to me (git pull request is nicer). This is the same way as how I have been treating gitk, and to a lesser degree various foreign SCM interfaces, so you know the drill. I expect that things that start their life in the contrib/ area to graduate out of contrib/ once they mature, either by becoming projects on their own, or moving to the toplevel directory. On the other hand, I expect I'll be proposing removal of disused and inactive ones from time to time. If you have new things to add to this area, please first propose it on the git mailing list, and after a list discussion proves there are some general interests (it does not have to be a list-wide consensus for a tool targeted to a relatively narrow audience -- for example I do not work with projects whose upstream is svn, so I have no use for git-svn myself, but it is of general interest for people who need to interoperate with SVN repositories in a way git-svn works better than git-svnimport), submit a patch to create a subdirectory of contrib/ and put your stuff there. -jc
