Björn Schießle	4f438eee56	preserve information if it is a rename operation or not	9 years ago
Bjoern Schiessle	e4b451491b	make sure that we always remove the file again from the cache after the version was created	9 years ago
Bjoern Schiessle	93ed965cbb	fix creation of versions of encrypted files on external storages ... in order to create a 1:1 copy of a file if a version gets created we need to store this information on copyBetweenStorage(). This allows us to by-pass the encryption wrapper if we read the source file.	9 years ago
Lukas Reschke	c427bf3b5d	Make sure that the encrypted version is set ... The code path called when using external storage with WebDAV is using `\OC\Files\Storage\Wrapper\Encryption::getMetaData` which did not contain the actual encrypted version inside the cache entry version. This lead to the following: 1. User uploaded a file 2. File is created and `\OC\Files\Storage\Wrapper\Encryption::getMetaData` is called. It has an empty `encryptedVersion` but sets `encrypted` to either `true` or `false`. 3. The call when updating the file cache will use the old version.	9 years ago
Bjoern Schiessle	7b9d53b7ea	no need to calculate the header size, if the first block contain a header we already know the size	9 years ago
Lukas Reschke	676041ba7e	Ensure that stored version is at least 1 for cross-storage copy ... In case of a move operation from an unencrypted to an encrypted storage the old encrypted version would stay with "0" while the correct value would be "1". Thus we manually set the value to "1" for those cases. See also https://github.com/owncloud/core/issues/23078	9 years ago
Lukas Reschke	72c8187cbb	Keep "encryptedVersion" when calling `\OC\Files\View::copy` ... When calling `\OC\Files\View::copy` we should also keep the version to ensure that the file will always have the correct version attached and can be successfully decrypted. To test this the following steps are necessary (from https://github.com/owncloud/core/issues/22781#issuecomment-191328982): 1. setup a new ownCloud 9.0 beta2 2. enable encryption 2. upload a docx (5.7MB large) 3. upload the same file again and overwrite the existing file 4. I can download the original file and the first version 5. I restore the first version 6. restored version can no longer be downloaded with the error described above The manual cache operation in `\OCA\Files_Versions\Storage` is unfortunately necessary since `\OCA\Files_Versions\Storage::copyFileContents` is not using `\OCP\Files\Storage::moveFromStorage` in the case when an object storage is used. Due to the workaround added in 54cea05271 the stream is directly copied and thus bypassing the FS.	9 years ago
Lukas Reschke	933f60e314	Update author information ... Probably nice for the people that contributed to 9.0 to see themselves in the AUTHORS file :)	9 years ago
Bjoern Schiessle	834b51b83b	recalculate unencrypted size if we assume that the size stored in the db is not correct	9 years ago
Vincent Petry	a9e0cfad8b	Check delete permission before attemping copy+delete ... Some move operations when cross-storage will be replaced by copy and delete. Before attempting this, first check whether the source storage has delete permissions. This also prevents renaming system-wide external storages.	9 years ago
Bjoern Schiessle	9dc759b4dc	remember signature version and only set it on update to make sure that other ... apps like files_versions still get the old signature version	9 years ago

Björn Schießle	cf3a8f274f	make it backward compatible to work with signed and un-signed files	9 years ago
Vincent Petry	19980be116	Fix part file partial cache logic in encryption code ... The encryption code uses partial cache entries for the part file (which are not stored in the database) but are useful for other parts of the code to retrieve the file size again. This means that in the fixed code $info was empty, so getData() could not be called. The fix makes sure to support both cases when the cache entry exists and doesn't.	9 years ago
