Michael Eischer 73c9780321 backup: store but warn if extended metadata for item is incomplete 
Files were not included in the backup if the extended metadata for the
file could not be read. This is rather drastic. Instead settle on
returning a warning but still including the file in the backup.

Michael Terry 88f59fc2d6 json: switch backup and restore errors from string to struct types 
This keeps backwards compatibility with the previous empty structs.
And maybe we'd want to put other fields into the inner struct later,
rather than the outer message.

Michael Terry ad2585af67 backup: show actual error strings in --json mode 
Previously, an error JSON fragment would look like:
{"message_type": "error", "error": {}}

This is because encoding/json cannot marshal an error interface.
Instead, we now call .Error() to get the string value.

Michael Terry 6a97833337 restore: clean up error handling when restoring metadata 
- Fix a logic error that instead of reporting the *first*
  metadata-setting error that appears, we were instead reporting the
  *last* error (and only if the lchown call failed!).
- Don't show any errors when setting metadata for files in non-root
  mode (things like timestamps, attributes). Previously, only lchown
  errors were skipped. But other kinds of attribute errors make sense
  to skip as well. The code path happened to work correctly before
  because of the above logic error. But once that was fixed, this
  change needed to happen too.

Michael Eischer 5d6ce59a8d restorer: also truncate files if their content is already uptodate 
Files for which no blobs have to be restored, still have to be truncated
to the correct size. Take a file with content "foobar" that should be
replaced by restore with content "foo". The first three bytes are
already uptodate, such that no data has to be written. As file
truncation normally happens when writing data, a special case is
necessary.

This no blobs written special case is unified with the empty file
special case.

Michael Eischer 4b364940aa s3: use http client with configured timeouts for s3 IAM communication 
The default client has no timeouts configured opening network

would wait for until the operating system gives up, which will take
several minutes.

Michael Eischer aedead2823 ui/termstatus: fix clearing status lines 
To clear the status lines, they should be set to an empty array to
prevent future updates of those lines. Setting the status lines to an
array containing an empty string is wrong as this causes the output to
continuously add that empty status line after each message.

Calls to `List(ctx, ...)` are usually stopped by canceling the context
once no further entries are required by the caller. Thus, don't log the
final error if the used context was canceled.

Michael Eischer 027cc64737 repository: fix prune heuristic to allow resuming interrupted runs 
Pack files created by interrupted prune runs, appear to consist only of
duplicate blobs on the next run. This caused the previous heuristic to
ignore those pack files. Now, a duplicate blob in a specific pack file
is also selected if that pack file only contains duplicate blobs. This
allows prune to select the already rewritten pack files.

Michael Eischer 5f7b48e65f index: replace Save() method with Rewrite and SaveFallback 
Rewrite implements a streaming rewrite of the index that excludes the
given packs. For this it loads all index files from the repository and
only modifies those that require changes. This will reduce the index
churn when running prune. Rewrite does not require the in-memory index
and thus can drop it to significantly reduce the memory usage.

However, `prune --unsafe-recovery` cannot use this strategy and requires
a separate method to save the whole in-memory index. This is now handled
using SaveFallback.

Michael Eischer 57f9739573 forget: Add --unsafe-allow-remove-all option 
To prevent accidentally wiping all snapshots from a repository, that
option can only be used if either a snapshot filter or a keep policy is
specified.

Essentially, the option allows `forget --tag something
--unsafe-allow-remove-all` calls to remove all snapshots with a specific
tag.
 2024-05-24 20:45:33 +02:00
Michael Eischer c0e1f36830 forget: refuse deleting the last snapshot in a snapshot group 
`--keep-tag invalid-tag` was previously able to wipe all snapshots in a
repository. As a user specified a `--keep-*` option this is likely
unintentional. This forbid deleting all snapshot if a `--keep-*` option
was specified to prevent data loss. (Not specifying such an option
currently also causes the command to abort)

Michael Eischer e4a48085ae backend/retry: feature flag new retry behavior 2024-05-24 20:24:02 +02:00
Michael Eischer 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.
 2024-05-24 20:24:02 +02:00
Michael Eischer 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.
 2024-05-24 20:24:02 +02:00
Michael Eischer 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.
 2024-05-24 20:24:02 +02:00
Michael Eischer 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.
 2024-05-24 20:24:02 +02:00
Michael Eischer a3633cad9e retry: explicitly log failed requests 
This simplifies finding the request in the log output that cause an
operation to fail.
