Nick Craig-Wood	bb6cfe109d	crypt: fix reading 0 length files ... In an earlier patch d5afcf9e34 crypt: try not to return "unexpected EOF" error This introduced a bug for 0 length files which this fixes which only manifests if the io.Reader returns data and EOF which not all readers do. This was failing in the integration tests.	2023-04-24 16:54:40 +01:00

albertony	9172c9b3dd	crypt: reduce allocations ... This changes crypt's use of sync.Pool: Instead of storing slices it now stores pointers pointers fixed sized arrays. This issue was reported by staticcheck: SA6002 - Storing non-pointer values in sync.Pool allocates memory A sync.Pool is used to avoid unnecessary allocations and reduce the amount of work the garbage collector has to do. When passing a value that is not a pointer to a function that accepts an interface, the value needs to be placed on the heap, which means an additional allocation. Slices are a common thing to put in sync.Pools, and they're structs with 3 fields (length, capacity, and a pointer to an array). In order to avoid the extra allocation, one should store a pointer to the slice instead. See: https://staticcheck.io/docs/checks#SA6002	2023-03-26 14:28:15 +02:00

Nick Craig-Wood	d5afcf9e34	crypt: try not to return "unexpected EOF" error ... Before this change the code wasn't taking into account the error io.ErrUnexpectedEOF that io.ReadFull can return properly. Sometimes that error was being returned instead of a more specific and useful error. To fix this, io.ReadFull was replaced with the simpler readers.ReadFill which is much easier to use correctly.	2023-03-22 16:23:37 +00:00

Nick Craig-Wood	e43b5ce5e5	Remove github.com/pkg/errors and replace with std library version ... This is possible now that we no longer support go1.12 and brings rclone into line with standard practices in the Go world. This also removes errors.New and errors.Errorf from lib/errors and prefers the stdlib errors package over lib/errors.	2021-11-07 11:53:30 +00:00

Dominik Mydlil	3fe2aaf96c	crypt: support timestamped filenames from --b2-versions ... With the file version format standardized in lib/version, `crypt` can now treat the version strings separately from the encrypted/decrypted file names. This allows --b2-versions to work with `crypt`.

Nick Craig-Wood	1648c1a0f3	crypt: calculate hashes for uploads from local disk ... Before this change crypt would not calculate hashes for files it was uploading. This is because, in the general case, they have to be downloaded, encrypted and hashed which is too resource intensive. However this causes backends which need the hash first before uploading (eg s3/b2 when uploading chunked files) not to have a hash of the file. This causes cryptcheck to complain about missing hashes on large files uploaded via s3/b2. This change calculates hashes for the upload if the upload is coming from a local filesystem. It does this by encrypting and hashing the local file re-using the code used by cryptcheck. For a local disk this is not a lot more intensive than calculating the hash.

Nick Craig-Wood	d0d6b83a7a	fs/accounting: rework to enable accounting to work with crypt and b2 ... This removes the old system of part accounting and replaces it with a system of popping off the accounting reader and wrapping up new ones as necessary. This makes it much easier to carry the context down the chain of wrapped readers and get the limiting as near as possible to the output. This makes the accounting more accurate and the bandwidth limiting smoother. Fixes #2029 and Fixes #1443	2018-02-02 15:14:41 +00:00
