In addition to regular file deletions, the removefiles argument passed
to adjustTree may contain removed submodules. When making the new
tree, filter these out in the same way that is done for regular files
so that the deletion is propagated.
When the recorded submodule commit changes on an adjusted branch, the
change is carried in the function that reverseAdjustedCommit passes
for adjustTree's adjusttreeitem parameter. Update the CommitObject
handling in adjustTree to consider adjusttreeitem so that a submodule
change is synced back.
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.
Goal is to make git-annex faster by using ByteString for all the
worktree traversal. For now, this is focusing on Command.Find,
in order to benchmark how much it helps. (All other commands are
temporarily disabled)
Currently in a very bad unbuildable in-between state.
Prevents merging the import from deleting the non-preferred files from
the branch it's merged into.
adjustTree previously appended the new list of items to the old, which
could result in it generating a tree with multiple files with the same
name. That is not good and confuses some parts of git. Gave it a
function to resolve such conflicts.
That allowed dealing with the problem of what happens when the import
contains some files (or subtrees) with the same name as files that were
filtered out of the export. The files from the import win.
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.)
Added graftTree but it's buggy.
Should use graftTree in Annex.Branch.graftTreeish; it will be faster
than the current implementation there.
Started Annex.Import, but untested and it doesn't yet handle tree
grafting.
So it will be available later and elsewhere, even after GC.
I first though to use git update-index to do this, but feeding it a line
with a tree object seems to always cause it to generate a git subtree
merge. So, fell back to using the Git.Tree interface to maniupulate the
trees, and not involving the git-annex branch index file at all.

Restarting a crashing git process could result in filename encoding issues
when not in a unicode locale, as the restarted processes's handles were not
read in raw mode.
Since rawMode is always used when starting a coprocess, didn't bother
to parameterise it and just always enable it for simplicity.

When adding a tree like a/b/c/d when a/b already exists, fixes the bug that
the tree that got created was a/b/a/b/c/d
Just need to flatten out the top N directories of the tree that's being
grafted in, so we get the c/d part. This was complicated by the Tree
data type being a rose tree rather than a regular tree.

The modification flag was not being set when making modifications deep
in a tree, so parent trees were not updated to contain the modified tree.
Seems to have exposed another bug where the wrong filename gets grafted in.

Only reverse adjust the changes in the commit, which means that adjustments
do not need to be generally cleanly reversable.
For example, an adjustment can unlock all locked files, but does not need
to worry about files that were originally unlocked when reversing, because
it will only ever be run on files that have been changed. So, it's ok
if it locks all files when reversed, or even leaves all files as-is when
reversed.
extractTree has to parse the whole input list in order to generate a tree,
so convert interface to non-streaming.
Some quick memory benchmarks in a repo with 60k files
don't look too bad despite not streaming.
To stream, without building up a whole tree object, one way would
be a new interface:
adjustTree :: MonadIO m :: (TreeItem -> m (Maybe TreeItem)) -> Ref -> Repo -> m Sha
This would only need to buffer tree objects from the current one down
to the root, in order to update trees when a TreeItem is changed.
But, while it supports changing items in the tree, and removing items,
it does not support adding new items, or moving items from one directory to
another.
