Previously we had the "staged" state to ensure we didn't add a commit
object without the associated dirtree, etc. However it's
easier/better to just ensure in the pull command that we have all
referenced objects.
Also change pull to download metadata first. This will allow adding
a progress bar later.
Expose the lower-level functionality in libostree, change checkout
builtin to be a higher level driver. This will allow us to more
easily improve the "checkout" builtin..
Continuing from 16c0cfe9b5, we now have
the problem that we're removing the executable bit, which obviously
breaks things when we chroot in for a build. Fix this by masking over
our bits.
We want to support both "bare" lookups where "foo" can be local, or in
any remote, as well as prefixed ones for a specific remote.
This fixes ostree-pull noticing that nothing has changed.
Before we were creating randomly-named temporary files in repo/tmp
when downloading via pull, but that means if the download process is
interrupted, we have to redownload everything again.
Let's still keep the concept of a "transaction" where files are
stored in the repository as atomically as possible (i.e. we
do a bunch of rename() calls), but now we also have an explicit
"tmp/pending/objects" directory that contains named objects.
This allows us to then skip redownloading things that are pending.
The builder wants the ability to mark a given file as e.g. setuid. To
implement this, the repo now has a callback-based API when importing a
directory to modify or remove items.
The commit tool accepts a "statoverride" file as input which looks like:
+mode /path/to/file
If multiple files have the same hash, we need to ensure we're not
overwriting other tempfiles in the same transaction. Instead
just delete them, since we know they're in the repo.
I'm trying to keep ostree as being closer to just being the versioning
filesystem, so let's split out the triggers into a different binary
(although still namespaced ostree-).
The tar files we're making of artifacts don't include parent
directories. Now we could change the builder to make them, but we can
also just autocreate them on import. Mode 0755 with no xattrs seems
OK here.
It's pretty trivial to map a previously existing commit tree into a
mutable tree too. While we're here change the command line arguments
for commit so that we can now properly overlay any combination of
directory, commit, or tarfile.
Rather than offering high level "commit directory", instead perform
operations on a mtree. Commits are treated more like regular objects.
Change the commit builtin to drive this all at a lower level.
