Rescued from commit 11d6e2e260 which removed
db benchmarks in favor of benchmarking arbitrary git-annex commands. Which
is nice and general, but microbenchmarks are useful too.
It would have been a lot less round-about to just make git annex dead
also add the uuids of sameas remotes to the trust.log as dead.
But, that would fail in the case where there's an unmerged other clone
that has a sameas remote that the current repo does not know about.
Then it would not get marked as dead.
Handling it at transition time avoids that scenario.
Note that the generation of trustmap' in dropDead should only
happen once, due to the partial application.
This solves the problem of sameas remotes trampling over per-remote
state. Used for:
* per-remote state, of course
* per-remote metadata, also of course
* per-remote content identifiers, because two remote implementations
could in theory generate the same content identifier for two different
peices of content
While chunk logs are per-remote data, they don't use this, because the
number and size of chunks stored is a common property across sameas
remotes.
External special remote had a complication, where it was theoretically
possible for a remote to send SETSTATE or GETSTATE during INITREMOTE or
EXPORTSUPPORTED. Since the uuid of the remote is typically generate in
Remote.setup, it would only be possible to pass a Maybe
RemoteStateHandle into it, and it would otherwise have to construct its
own. Rather than go that route, I decided to send an ERROR in this case.
It seems unlikely that any existing external special remote will be
affected. They would have to make up a git-annex key, and set state for
some reason during INITREMOTE. I can imagine such a hack, but it doesn't
seem worth complicating the code in such an ugly way to support it.
Unfortunately, both TestRemote and Annex.Import needed the Remote
to have a new field added that holds its RemoteStateHandle.
I found a way to avoid inheritance complicating anything outside of
Logs.Remote. It seems fine to require all inherited values to be
inherited and not set in the sameas remote's config. Since inherited
values will be used for stuff like encryption and perhaps chunking, which
control the actual content stored on the remote, it seems likely that
there will not be any reason to need them to vary between two remotes
that access the same underlying data store.
The newer version of containers is free; the minimum ghc version is
bundled with a newer version than that.
Initremote sets that, so after both initremote and enableremote,
the git config will be set.
Any remote that does not use Annex.SpecialRemote won't set
annex-config-uuid. But that's only Remote.Git, which doesn't use
RemoteConfig anyway.
Had a report of close throwing ErrorBusy on CIFS.
Retrying up to 16 seconds is a balance between hopefully waiting long
enough for the problem to clear up and waiting so long that git-annex seems
to hang.
The new dependency is free; persistent depends on unliftio-core.
This is a special remote and a git remote at the same time; git can pull
and push to it and git-annex can use it as a special remote.
Remote.Git has to check if it's configured as a git-lfs special remote
and sets it up as one if so.
Object methods not implemented yet.
In 40ecf58d4b I changed the license of code I
wrote from GPL to AGPL. But, two files containing code I wrote combined
with code by others were updated to say their license is AGPL, while in
fact part of it was (the code I wrote) but part remained under the original
license (the code written by others).
Remote/Ddar.hs is now changed entirely back to GPL 3.
Annex/DirHashes.hs stays AGPL, but I broke out Utility/MD5.hs with the code
not written by me, and corrected its license statement to GPL-2, which
is the actual version of the GPL included with the code in its original
distribution at http://www.cs.ox.ac.uk/people/ian.lynagh/md5/
Drop support for building with ghc older than 8.4.4, and with older
versions of serveral haskell libraries than will be included in Debian 10.
The only remaining version ifdefs in the entire code base are now a couple
for aws!
This commit should only be merged after the Debian 10 release.
And perhaps it will need to wait longer than that; it would make
backporting new versions of git-annex to Debian 9 (stretch) which
has been actively happening as recently as this year.
This commit was sponsored by Ilya Shlyakhter.
The hash was actually not being fully evaluated before, used rnf to fix
that.
The added dependency on deepseq is a free dependency, because eg text
depends on it.
* Added mimeencoding= term to annex.largefiles expressions.
This is probably mostly useful to match non-text files with eg
"mimeencoding=binary"
* git-annex matchexpression: Added --mimeencoding option.
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.
Does not yet have a way to update with new information from the
git-annex branch, which will be needed when multiple repos are importing
from the same remote.
List all current AGPL files in COPYRIGHT; several that were GPL have had
new AGPL code added.
In git-annex.cabal, use AGPL-3 as the overall license, since it's not
possible to build git-annex without AGPL code anymore.
Like with the network-uri split, cabal will automatically turn off the flag
when building with an old network.
I have not tested building with the new network-3.0.0.0 yet; several
other dependencies including aws are still pinned on network-2.*
