add support for staging other types of blobs, like symlinks, into the index Also added a utility TopFilePath type, which could stand to be used more widely.

{- git FilePath library
-
- Different git commands use different types of FilePaths to refer to
- files in the repository. Some commands use paths relative to the
- top of the repository even when run in a subdirectory. Adding some
- types helps keep that straight.
-
git style quoting for ActionItemOther Added StringContainingQuotedPath, which is used for ActionItemOther. In the process, checked every ActionItemOther for those containing filenames, and made them use quoting. Sponsored-by: Graham Spencer on Patreon

update licenses from GPL to AGPL This does not change the overall license of the git-annex program, which was already AGPL due to a number of sources files being AGPL already. Legally speaking, I'm adding a new license under which these files are now available; I already released their current contents under the GPL license. Now they're dual licensed GPL and AGPL. However, I intend for all my future changes to these files to only be released under the AGPL license, and I won't be tracking the dual licensing status, so I'm simply changing the license statement to say it's AGPL. (In some cases, others wrote parts of the code of a file and released it under the GPL; but in all cases I have contributed a significant portion of the code in each file and it's that code that is getting the AGPL license; the GPL license of other contributors allows combining with AGPL code.)

wip RawFilePath 2x git-annex find speedup Finally builds (oh the agoncy of making it build), but still very unmergable, only Command.Find is included and lots of stuff is badly hacked to make it compile. Benchmarking vs master, this git-annex find is significantly faster! Specifically: num files old new speedup 48500 4.77 3.73 28% 12500 1.36 1.02 66% 20 0.075 0.074 0% (so startup time is unchanged) That's without really finishing the optimization. Things still to do: * Eliminate all the fromRawFilePath, toRawFilePath, encodeBS, decodeBS conversions. * Use versions of IO actions like getFileStatus that take a RawFilePath. * Eliminate some Data.ByteString.Lazy.toStrict, which is a slow copy. * Use ByteString for parsing git config to speed up startup. It's likely several of those will speed up git-annex find further. And other commands will certianly benefit even more.

convert TopFilePath to use RawFilePath Adds a dependency on filepath-bytestring, an as yet unreleased fork of filepath that operates on RawFilePath. Git.Repo also changed to use RawFilePath for the path to the repo. This does eliminate some RawFilePath -> FilePath -> RawFilePath conversions. And filepath-bytestring's </> is probably faster. But I don't expect a major performance improvement from this. This is mostly groundwork for making Annex.Location use RawFilePath, which will allow for a conversion-free pipleline.

finish CommandStart transition The hoped for optimisation of CommandStart with -J did not materialize. In fact, not runnign CommandStart in parallel is slower than -J3. So, CommandStart are still run in parallel. (The actual bad performance I've been seeing with -J in my big repo has to do with building the remoteList.) But, this is still progress toward making -J faster, because it gets rid of the onlyActionOn roadblock in the way of making CommandCleanup jobs run separate from CommandPerform jobs. Added OnlyActionOn constructor for ActionItem which fixes the onlyActionOn breakage in the last commit. Made CustomOutput include an ActionItem, so even things using it can specify OnlyActionOn. In Command.Move and Command.Sync, there were CommandStarts that used includeCommandAction, so output messages, which is no longer allowed. Fixed by using startingCustomOutput, but that's still not quite right, since it prevents message display for the includeCommandAction run inside it too.
