Michael Eischer 0c1ba6d95d backend: remove unused Location method 2024-05-18 21:38:31 +02:00
Michael Eischer 1d6d3656b0 repository: move backend.LoadAll to repository.LoadRaw 
LoadRaw also includes improved context cancellation handling similar to the
implementation in repository.LoadUnpacked.

The removed cache backend test will be added again later on.

Michael Eischer 47232bf8b0 backend: move LimitReadCloser to util package 
The helper is only intended for usage by backend implementations.

Michael Eischer 53d15bcd1b retry: add circuit breaker to load method 
If a file exhausts its retry attempts, then it is likely not accessible
the next time. Thus, immediately fail all load calls for that file to
avoid useless retries.

Michael Eischer 394c8ca3ed rest/rclone/s3/sftp/swift: move short file detection behind feature gate 
These backends tend to use a large variety of server implementations.
Some of those implementations might prove problematic with the new
checks.

Michael Eischer aeb7eb245c retry: do not retry permanent errors 
This is currently gated behind a feature flag as some unexpected
interactions might show up in the wild.
 2024-05-18 19:59:26 +02:00
Michael Eischer bf8cc59889 Use generic backend-error-redesign feature flag instead of http-timeouts 
An individual flag for each change of the backend error handling would
be too finegrained. Thus, add a generic flag.

Michael Eischer b1a8fd1d03 rest: fix and cleanup closing of http response body 
If client.Do returns an error, then there's no body that has to be
closed. For requests for which we are not interested in the response
body, immediately drain and close the body to make sure it isn't
forgotten later on.

This change in particular adds the missing `Close()` call for the
`List()` command.

 2024-01-09 18:28:31 +01:00
Michael Eischer 2e8de9edfd rclone: Workaround for incorrect "not found" errors while listing files 
rclone returns a "not found" error if an internal error occurs while
listing a folder. Ignoring this error lets restic erroneously think that
there are no files, which can cause `prune` to wipe the whole
repository.

the underlying backend. Thus, move MemorizeList one layer up.

Michael Manganiello 41f70f1f4f backend/sftp: Add sftp.args option 
Allow setting custom arguments for the `sftp` backend, by using the
`sftp.args` option. This is similar to the approach already implemented
in the `rclone` backend, to support new arguments without requiring
future code changes for each different SSH argument.

Michael Eischer f750aa8dfb backend/limiter: replace juju/ratelimit with x/time/rate 2023-10-17 22:49:25 +02:00
Michael Eischer 4a33370072 backend: Fix unreliable TestListCancel/Timeout test 
The test uses `WithTimeout` to create a context that cancels the List
operation after a given delay. Several backends internally use a derived
child context created using WithCancel.

The cancellation of a context first closes the done channel of the
context (here: the `WithTimeout` context) and _afterwards_ propagates
the cancellation to child contexts (here: the `WithCancel` context).
Therefor if the List implementation uses a child context, then it may
take a moment until that context is also cancelled. Thus give the
context cancellation a moment to propagate.

Michael Eischer 307aeb6849 rest: Don't return error if listing non-existent directory 
When transferring a repository from S3 to, for example, a local disk
then all empty folders will be missing.

When saving files, the missing intermediate folders are created
automatically. Therefore, missing directories can be ignored by the
`List()` operation.

Michael Eischer f903db492c backend: let ParseConfig return a Config pointer 
In order to change the backend initialization in `global.go` to be able
to generically call cfg.ApplyEnvironment() for supported backends, the
`interface{}` returned by `ParseConfig` must contain a pointer to the
configuration.

An alternative would be to use reflection to convert the type from
`interface{}(Config)` to `interface{}(*Config)` (from value to pointer
type). However, this would just complicate the type mess further.

 2023-05-26 19:34:14 +02:00
greatroar 51dc80be5b backend: Use IoctlSetPointerInt for tcsetpgrp 
This function casts its argument to int32 before passing it to the
system call, so that big-endian CPUs read the lower rather than the
upper 32 bits of the pid.

This also gets rid of the last import of "unsafe" in the Unix build.
I changed syscall to x/sys/unix while I was at it, to remove one more
import line. The constants and types there are aliases for their syscall
counterparts.
