* chore: move streamCopy implementation from `OC_Helper` to `OCP\Files`Ferdinand Thiessen2025-05-161-2/+3
| | | | | | | | | The function was already there but called the legacy version. So moved the implementation and migrated all usages of it. Sadly the interface was slightly different so adjusted it to be compatible with both legacy and the OCP one. Signed-off-by: Ferdinand Thiessen <opensource@fthiessen.de>

* updateEncryptedVersion: cleanup on target if cache already got renamedJonas Meurer2022-01-121-1/+10
| | | | | | | | | | | | | | | | | When moving a file to trash with encryption enabled, the cache gets moved before the actual file. According to @icewind1991 this is in order to not break object storage. When moving a file from an unencrypted storage (e.g. a collectives storage) to the encrypted trashbin storage, this causes errors, see This commit fixes it by doing `updateEncryptedVersion()` on the target cache entry *if* the source cache entry doesn't exist anymore, but the corresponding target cache entry does exist already.

| | | | | | | | | | | In case of error there is no guarantee that $source or $target is set or is a resource when handling an error. Without this fix, there's a risk that fclose will fail and the actual exception will not be thrown, making it impossible to find out about the root cause.

* Fix truncation of files upon read when using object store and encryption.Alan Meeson2021-10-231-2/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using and object store as primary storage and using the default encryption module at the same time, any encrypted file would be truncated when read, and a text error message added to the end. This was caused by a combination of the reliance of the read functions on on knowing the unencrypted file size, and a bug in the function which calculated the unencrypted file size for a given file. In order to calculate the unencrypted file size, the function would first skip the header block, then use fseek to skip to the last encrypted block in the file. Because there was a corresponence between the encrypted and unencrypted blocks, this would also be the last encrypted block. It would then read the final block and decrypt it to get the unencrypted length of the last block. With that, the number of blocks, and the unencrypted block size, it could calculate the unencrypted file size. The trouble was that when using an object store, an fread call doesn't always get you the number of bytes you asked for, even if they are available. To resolve this I adapted the stream_read_block function from lib/private/Files/Streams/Encryption.php to work here. This function wraps the fread call in a loop and repeats until it has the entire set of bytes that were requested, or there are no more to get. This fixes the imediate bug, and should (with luck) allow people to get their encrypted files out of Nextcloud now. (The problem was purely on the decryption side). In the future it would be nice to do some refactoring here. I have tested this with image files ranging from 1kb to 10mb using Nextcloud version 22.1.0 (the nextcloud:22.1-apache docker image), with sqlite and a Linode object store as the primary storage.
