Looks good so far.

I didn't remember seeing tests for the new Sabre nodes, please add some. (I expect codecov will complain about this).

Can you clarify the part about Webdav COPY vs $storage->restoreVersion. If they are connected, does the error message propagate properly when restoring to another file than the original one ? (no HTTP 500).

+use Sabre\HTTP\RequestInterface;
+use Sabre\HTTP\ResponseInterface;

+class CorePlugin extends ServerPlugin {


please rename to something that says "plugin to avoid deletion on copy" or something. CorePlugin is the wrong name for this. Also please add PHPDoc to describe this.

+		if ($sourceNode instanceof ICopySource) {
+			$copySuccess = $sourceNode->copy($destinationNode->getFileInfo()->getPath());
+		}
+		if (!$copySuccess) {


wouldn't doing a simple return here let the actual CorePlugin do the fallback ? this would remove the need for duplicating the response related code below

No because the fall back will still perform the delete of the target.

Write a short sentence for the PHPDoc, at least on the interface.

+		//TODO: inject

can we inject the root folder ? (lazy root folder if possible)

+		$copySuccess = false;
+		if ($sourceNode instanceof ICopySource) {
+			$copySuccess = $sourceNode->copy($destinationNode->getFileInfo()->getPath());


Do I understand it correctly that doing a Webdav COPY is not the same as calling $storage->restoreVersion() ?
If it was I'd expect to have some validation to make sure the COPY is operating on the same storage + target file and fail if it doesn't.

Do I understand it correctly that doing a Webdav COPY is not the same as calling $storage->restoreVersion() ?

within the implementation of copy() restoreVersion() is called if applicable

PVince81 · 2017-10-23T12:25:49Z

+		/** @var IVersionedStorage | Storage $storage */
+		$versions = $storage->getVersions($internalPath);
+		return array_map(function($version) use ($storage, $internalPath) {
+			return new MetaFileVersionNode($this, $version['version'],$storage, $internalPath);


missing space ],$storage

PVince81 · 2017-10-23T12:28:09Z

+ * Interface IVersionedStorage - storage layer to access version of a file
+ *
+ * @package OCP\Files\Storage
+ * @since 10.1.0


so no backports then?

we need to make a decision on this - since no database change is involved we can add this to 10.0.x as well

 		$path = Files\Filesystem::normalizePath($args['path']);
+		$user = isset($args['user']) ? $args['user'] : \OC_User::getUser();


the user is now part of the hook arguments to make sure the correct user is used

Wow, our code can be quite obscure sometimes. I was confused when seeing that you extended the rollback event to include user, but this method is called post_delete.

Turns out that hook registration in base.php is wiring the "rollback" event to the "post_delete_versions" method here.

old check was against string "true" and you replaced it with boolean true. I hope this won't break existing configs.

Of course, I'd expect the original code to use booleans...

Storage::DEFAULTENABLED is true and not 'true' and the old code used == and not ===/!==

PVince81 · 2017-11-17T09:39:21Z

BUG: encryption + share from a system-wide ext storage, available for admin only (not recipient): as share recipient, revert file to older version: preview does not update on-disk even after page refresh.

It does work for local files.

DeepDiver1975 · 2017-11-17T09:42:53Z

for previews there is a follow up pr - #29319

PVince81 · 2017-11-17T09:44:47Z

@DeepDiver1975 does the follow up solve the problem ? I had the impression that it's a hook related bug when using ext storage + share, since regular scenarios work already.

If you intend to fix it in that PR, please add it as checklist item there.

The whole preview generation will be changed - fixing anything in here is useless work.
As example: I'm currently integrating objectstore versioning based on this branch - no previews are displayed at all.

PVince81 · 2017-11-17T09:49:58Z

Thanks for clarification. I wasn't aware that the DAV previews would also touch the lower levels.

Sounds good then.

@DeepDiver1975 can you backport ICopySource to stable10 so we can fix #29561 ?

https://github.com/owncloud/core/pull/29257/files#diff-efc44835a2c59b3707c965b80a3d669e
will files_versions then have a new version in info.xml (currently 1.3.0)?

DeepDiver1975 · 2017-11-29T11:27:35Z

will files_versions then have a new version in info.xml (currently 1.3.0)?

I see no reason to bump the version. Are you asking to find out about the API change?

cortho · 2017-11-29T11:30:45Z

ok.

Are you asking to find out about the API change?

yes, this was the idea behind
