Its repeated opening and writing to the sqlite database somehow caused
inode cache information to occasionally be lost.
This loses code coverage, since running git-annex as a child process
prevents tracking what parts of the code are exercised. I have not looked
at the code coverage in a long time. It would probably be possible to
collect code coverage for the child procesess and merge it together.
On second thought, the extra time running the test suite is worth it.
It will be gained back once we finally get rid of direct mode.
There are two failing tests, same two that have been failing on windows
(though the failure does not look identical). So this should also spare me
the Windows VM while fixing.
This way a failure to clean up the main repo dir from a previous pass
can't result in reusing that repo, which won't be configured right for the
current pass.
No behavior changes, but this shows everywhere that a progress meter
could be displayed when hashing a file to add to the annex.
Many of the places don't make sense to display a progress meter though,
eg when importing the copy of the file probably swamps the hashing of
the file.
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.)
This way when there's a failure the output is available to understand
the problem. Should help with some intermittent test failures that I
have not been able to reproduce to understand why it's failing.
Does mean the test output is more verbose, but it was already very
verbose.
Avoid performing repository fixups for submodules and git-worktrees
when there's a .noannex file that will prevent git-annex from being
used in the repository.
This change is ok as long as the .noannex file is really going to prevent
git-annex from being used. But, init --force could override the file.
Which would result in the repo being initialized without the fixups
having run.
To avoid that situation decided to change init, to not let --force be used
to override a .noannex file. Instead the user can just delete the file.
What these generate is not really suitable to be used as a filename,
which is why keyFile and fileKey further escape it. These are just
serializing Keys.
Also removed a quickcheck test that was very unlikely to test anything
useful, since it relied on random chance creating something that looks
like a serialized key. The other test is sufficient for testing what
that was intended to test anyway.
init: When --version=5 is passed on a crippled filesystem, use a v5 direct
mode repo as requested, rather than upgrading to v7 adjusted unlocked.
Fixed test suite on crippled filesystems, making it request --version=5
to test direct mode.
Not the first time this kind of test suite breakage has happened..
It would be good to avoid somehow it looking up from .t and finding a git
repo. But just running the test suite from time to time outside of
git-annex would also let me notice these before the distribution packagers
do.

I've seen intermittent failures of the test suite with v6 for a long time,
it seems to have possibly gotten worse with the changes around v7. Or just
being unlucky; all tests failed today.
Seen on amd64 and i386 builders, repeatedly but intermittently:
unused: FAIL (4.86s)
Test.hs:928:
git diff did not show changes to unlocked file
And I think other such failures, all involving v7/v6 mode tests.
I managed to reproduce the unused failure with --keep-failures,
and inside the repo, git diff was indeed not showing any changes for
the modified unlocked file.
The two stats will be the same other than mtime; the old and new files have
the same size and inode, since the test case writes to the file and then
overwrites it.
Indeed, notice the identical timestamps:

I'm seeing this in Linux VMs; it doesn't happen on my laptop. I've also
not experienced the intermittent test suite failures on my laptop.
So, I hope that this small delay will avoid the problem.
Update: I didn't, indeed I then reproduced the same failure on my
laptop, so it must be due to something else. But keeping this change anyway
since not needing to worry about lowish-resolution mtime in the test suite seems
worthwhile.
Install new git hooks in this version.
This does beg the question of what to do if git later gets eg a
post-smudge hook, that could run git-annex smudge --update. I think the
thing to do in that case would be to make git-annex smudge --update
install the new hooks. That way, as the user uses git-annex, the hook
would be created pretty quickly and without needing any extra syscalls
except for when git-annex smudge --update is called.
I considered doing something like that for installation of the
post-checkout and post-merge hooks, which would have avoided the need
for v7. But the only place it was cheap to do it would be in git-annex smudge
which could cheaply notice that smudge.log didn't exist yet and so know
the hooks needed to be installed. But since smudge used to populate pointer
files, it would be quite surprising if a single git checkout/merge failed
to update the work tree, and so that idea didn't work out.
The other reason for v7 is psychological -- users don't need to worry
about whether they might be running an old version of git-annex that
doesn't support their v7 repository very well. And bug reports about
"v6" have gotten a bit of a bad association in my head since they often
hit one of the known limitations and didn't realize it was experimental.
