1 is a better choice than 0 because some programs use 0
as a special value; for example, GNU Tar warns of an
"implausibly old timestamp" with 0.

In practice, a lot of subjects are empty, because the commit date
and branch are sufficient identification. For example, rpm-ostree
does not use subjects. It also doesn't use the command-line ostree
commit tool, so this was not a problem there, but this makes the
behavior consistent.
Also adds a test that empty subjects and omitting the subject
are equivalent. The --timestamp is so that the commits do not
have different timestamps.

It's very useful for third-party applications to have someplace to store
their data guaranteed to be on the same device as the repo (thus
ensuring hardlinks) while still being shielded away from any of OSTree's
timely garbage collections.
We create a new "extensions/" subdirectory where apps can include
whatever they wish in "extensions/myapp/". This subdirectory is
completely unmanaged by ostree.
NB: I didn't bother making it a member of the OstreeRepo proper since we
don't really use it for anything else yet.

This was already supported by the commit modifier API, just needed to
expose it. This will also be used to test the libarchive API in a future
test.

Setting this causes commit to error out. There are other ways we
could do this in a more sophisticated fashion, such as via SystemTap
etc. But this has low-tech applicablity, works as non-root.
The reason I'm adding this is so that we can add test cases for
cleanup of the `tmp/staging-` directory.

The API supports this, and it's not hard for us to do in the command
line as well. One possible use case is separating "content
generation" in a separate server.

When I'm doing local development builds, it's quite common for me not
to want to accumulate history. There are also use cases for this on
build servers as well.
In particular, using this, one could write a build system that didn't
necessarily need to have access to (a copy of) the OSTree repository.
Instead, the build system would determine the last commit ID on the
branch, and pass that to a worker node, then sync the generated
content back.
The API supported generating custom commits that don't necessarily
reference the previous commit on the same branch, let's just expose
this in the command line for convenience.
I plan to also support this rpm-ostree.

%Z only uses seconds, so it's possible that we did the commit
in the same second, which made this test racy.
- Switch to full nanosecond precision using '%.Y' so it always differs
- Fix the inverted `cmp` usage
- Add a missing `ok`
OSTree's code for testing predates the `glib-tap.mk` making its
way into GLib. Let's switch to it, as it provides a number
of advantages.
By far the biggest advantage is that `make check` can start to run
most of the tests *in addition* to having them work installed.
This commit keeps the installed tests working, but `make check` turns
out to be really broken because...our TAP usage has bitrotted to say
the least. Fix that all up.
Do some hacks so that the tests work uninstalled as well - in
particular, `glib-tap.mk` and the bits encoded into
`g_test_build_filename()` assume *recursive* Automake (blah). Work
around that by creating a symlink when installed to loop back.
I noticed in the static deltas tests, there were some tests that
should have been under `-o pipefail` to ensure we properly propagate
errors.
There were a few places where we were referencing undefined variables.
Overall, this is clearly a good idea IMO.
External daemons like rpm-ostree want push notification any time a
change is made by an external entity. inotify provides notification,
but a problem is there's no easy way to monitor all of the refs.
In the past, there has been discussion of opt-in recursive timestamps:
https://lkml.org/lkml/2013/4/5/307
But in today's world, let's just bump the mtime on the repo itself, as
a central inotify point.
Closes: https://github.com/GNOME/ostree/pull/111
When I removed the `transaction` symlink, that made this test start
failing. Fix it by doing `chmod` on `repo/objects`, which is what the
core `ostree_repo_is_writable()` looks at.
rpm-ostree currently uses ostree_repo_checkout_tree(), which as a side
effect will use the uncompressed objects cache by default. This is
rather annoying if you're using rpm-ostree on a server-side
repository, because if you then rsync the repo, you'll be syncing out
the uncompressed objects unless you exclude them.
We added the ability to disable the uncompressed cache in the
repository config to fix this, but it's better to allow application
control over this. The uncompressed cache will in some future version
become opt in as well.
This new API further:
- Drops the `GFile` usage in favor of `openat` APIs
- Improves ergonomics by avoiding callers having to query the source
`GFileInfo` (and carry around a copy of `OSTREE_GIO_FAST_QUERYINFO`)
- Has a more extensible options structure
Per the comment, I rather crudely have the `ostree checkout` builtin
call both APIs to ensure some testing coverage.
However, I'd like to in the future have easier-to-set-up testing code
that calls `libtest.sh` to set up dummy data.
We already set all file mtimes to 0 so that they are constant
over all checkouts, and can be made constant with a known value from
the system where the ostree was created.
However, this was not happening for directories. Zero their mtimes too.
This is important for shipping a fontconfig cache in the ostree;
the fontconfig cache files embed a directory mtime.
