e4a48085ae backend/retry: feature flag new retry behavior 2024-05-24 20:24:02 +02:00

b1266867d2 repository: wait max 1 minutes for lock removal if context is canceled 
The toplevel context in restic only canceled if the user interrupts a
restic operation. If the network connection has failed this can require
waiting the full retry duration of 15 minutes which is a bad user
experience for interactive usage. Thus limit the delay to one minute in
this case.

98709a4372 retry: reduce total number of retries 
Retries in restic try to solve two main problems:
- retry a temporarily failed operation
- tolerate temporary network interruptions

The first problem only requires a few retries, whereas the last one benefits
primarily from spreading the requests over a longer duration.

Increasing the default multiplier and the initial interval works for
both cases. The first few retries only take a few seconds, while later
retries quickly reach the maximum interval of one minute. This ensures
that the total number of retries issued by restic will remain at around
21 retries for a 15 minute period. As the concurrency in restic is
bounded, retries drastically reduce the number of requests sent to a
backend. This helps to prevent overloading the backend.

512cd6ef07 retry: ensure that there's always at least one retry 
Previously, if an operation failed after 15 minutes, then it would never
be retried. This means that large backend requests are more unreliable
than smaller ones.

a60ee9b764 retry: limit retries based on elapsed time not count 
Depending on how long an operation takes to fail, the total retry
duration can currently vary between 1.5 and 15 minutes. In particular
for temporarily interrupted network connections, the former timeout is
too short. Thus always use a limit of 15 minutes.

74d90653e0 check: use ReadFull to load pack header in checkPack 
This ensures that the pack header is actually read completely.
Previously, for a truncated file it was possible to only read a part of
the header, as backend.Load(...) is not guaranteed to return as many
bytes as requested by the length parameter.

e734746f75 cache: forget cached file at most once 
This is inspired by the circuit breaker pattern used for distributed
systems. If too many requests fails, then it is better to immediately
fail new requests for a limited time to give the backend time to
recover.

By only forgetting a file in the cache at most once, we can ensure that
a broken file is only retrieved once again from the backend. If the file
stored there is broken, previously it would be cached and deleted
continuously. Now, it is retrieved only once again, all later requests
just use the cached copy and either succeed or fail immediately.

97a307df1a cache: Always use cached file if it exists 
A file is always cached whole. Thus, any out of bounds access will also
fail when directed at the backend. To handle case in which the cached
file is broken, then caller must call Cache.Forget(h) for the file in
question.

666a0b0bdb repository: streamPack: replace streaming with chunked download 
Due to the interface of streamPack, we cannot guarantee that operations
progress fast enough that the underlying connections remains open. This
introduces partial failures which massively complicate the error
handling.

Switch to a simpler approach that retrieves the pack in chunks of 32MB.
If a blob is larger than this limit, then it is downloaded separately.

To avoid multiple copies in memory, an auxiliary interface
`discardReader` is introduced that allows directly accessing the
downloaded byte slices, while still supporting the streaming used by the
`check` command.

the backup to fail, just ignore those errors.

It is only used for hardlink detection. Thus there it is not necessary
to store it for everything else.
