Nick Craig-Wood	a4c4ddf052	vfs: rename files in cache and cancel uploads on directory rename ... Before this change rclone did not cancel an uploads or rename the cached files in the directory cache when a directory was renamed. This caused issues with uploads arriving in the wrong place on bucket based file systems.

Leo Luan	c665201b85	vfs: support synchronous cache space recovery upon ENOSPC ... This patch provides the support of synchronous cache space recovery to allow read threads to recover from ENOSPC errors when cache space can be recovered from cache items that are not in use or safe to be reset/emptied . The patch complements the existing cache cleaning process in two ways. Firstly, the existing cache cleaning process is time-driven that runs periodically. The cache space can run out while the cache cleaner thread is still waiting for its next scheduled run. The io threads encountering ENOSPC return an internal error to the applications in this case even when cache space can be recovered to avoid this error. This patch addresses this problem by having the read threads kick the cache cleaner thread in this condition to recover cache space preventing unnecessary ENOSPC errors from being seen by the applications. Secondly, this patch enhances the cache cleaner to support cache item reset. Currently the cache purge process removes cache items that are not in use. This may not be sufficient when the total size of the working set exceeds the cache directory's capacity. Like in the current code, this patch starts the purge process by removing cache files that are not in use. Cache items whose access times are older than vfs-cache-max-age are removed first. After that, other not-in-use items are removed in LRU order until vfs-cache-max-size is reached. If the vfs-cache-max-size (the quota) is still not reached at this time, this patch adds a cache reset step to reset/empty cache files that are still in use but not dirtied. This enables application processes to continue without seeing an error even when the working set depletes the cache space as long as there is not a large write working set hoarding the entire cache space. By design this patch does not add ENOSPC error recovery for write IOs. Rclone does not empty a write cache item until the file data is written back to the backend upon close. Allowing more cache space to be consumed by dirty cache items when the cache space is already running low would increase the risk of exhausting the cache space in a way that the vfs mount becomes unreadable.	2020-08-25 21:12:06 +01:00
Nick Craig-Wood	15402e46c9	vfs: Add recovered items on cache reload to directory listings ... Before this change, if we restarted an upload after a restart then the file would get uploaded but never added to the directory listings. This change makes sure we add virtual items to the directory cache when reloading the cache so that they show up properly.	2020-06-30 12:03:39 +01:00
Nick Craig-Wood	939860eb85	vfs: vfscache make TestCacheCleaner test more reliable	2020-06-30 12:03:39 +01:00
Nick Craig-Wood	58a7faa281	vfs: Make tests run reliably ... On file Remove - cancel any writebacks in progress - ignore error message deleting non existent file if file was in the process of being uploaded Writeback - Don't transfer the file if it has disappeared in the meantime - Take our own copy of the file name to avoid deadlocks - Fix delayed retry logic - Wait for upload to finish when cancelling upload Fix race condition in item saving Fix race condition in vfscache test Make sure we delete the file on the error path - this makes cascading failures much less likely	2020-06-30 12:01:36 +01:00

Nick Craig-Wood	917cb4acb3	vfs: implement partial reads in --vfs-cache-mode full ... This allows reads to only read part of the file and it keeps on disk a cache of what parts of each file have been loaded. File data itself is kept in sparse files.	2020-06-30 12:01:36 +01:00
