Alexander Neumann e5c929b793 Fix rest-server tests
Since today, the rest-server needs to be explicitly told (via
`--no-auth`) that authentication is not necessary.

Automatically load Google auth
This change removes the hardcoded Google auth mechanism for the GCS
backend, instead using Google's provided client library to discover and
generate credential material.

Google recommend that client libraries use their common auth mechanism
in order to authorise requests against Google services. Doing so means
you automatically support various types of authentication, from the
standard GOOGLE_APPLICATION_CREDENTIALS environment variable to making
use of Google's metadata API if running within Google Container Engine.

Nick Craig-Wood 04c4033695 backend/rest: check HTTP error response for List
Before this change restic would attempt to JSON decode the error
message resulting in confusing `Decode: invalid character 'B' looking
for beginning of value` messages.  Afterwards it will return `List
failed, server response: 400 Bad Request (400)`

Alexander Neumann d8dcbc89d1 lock: Ignore invalid lock file
This commit fixes a bug introduced in
e9ea26884739a218bbab0248b634d2821be9c3ea: When an invalid lock is
encountered (e.g. if the file is empty), the code used to ignore that,
but now returns the error.

Now, invalid files are ignored for the normal lock check, and removed
when `restic unlock --remove-all` is run.

Closes #1652

Alexander Neumann 99f7fd74e3 backend: Improve Save()
As mentioned in issue [#1560](https://github.com/restic/restic/pull/1560#issuecomment-364689346)
this changes the signature for `backend.Save()`. It now takes a
parameter of interface type `RewindReader`, so that the backend
implementations or our `RetryBackend` middleware can reset the reader to
the beginning and then retry an upload operation.

The `RewindReader` interface also provides a `Length()` method, which is
used in the backend to get the size of the data to be saved. This
removes several ugly hacks we had to do to pull the size back out of the
`io.Reader` passed to `Save()` before. In the `s3` and `rest` backend
this is actively used.

Alexander Neumann 93210614f4 backend/retry: return worker function error and abort
This is a bug fix: Before, when the worker function fn in List() of the
RetryBackend returned an error, the operation is retried with the next
file. This is not consistent with the documentation, the intention was
that when fn returns an error, this is passed on to the caller and the
List() operation is aborted. Only errors happening on the underlying
backend are retried.

The error leads to restic ignoring exclusive locks that are present in
the repo, so it may happen that a new backup is written which references
data that is going to be removed by a concurrently running `prune`
operation.

The bug was reported by a user here:

Toby Burress cdb48a8970 Add tests for the eager-header refactor. 2018-02-22 01:14:04 +00:00
Toby Burress 4fd5f0b8a9 Refactor the eager-header reads for readability.
This pulls the header reads into a function that works in terms of the
number of records requested.  This preserves the existing logic of
initially reading 15 records and then falling back if that fails.

In the event of a header with more than 15 records, it will read all
records, including the already-seen final 15 records.

Alexander Neumann b5062959c8 backend: Relax requirement for new files
Before, all backend implementations were required to return an error if
the file that is to be written already exists in the backend. For most
backends, that means making a request (e.g. via HTTP) and returning an
error when the file already exists.

This is not accurate, the file could have been created between the HTTP
request testing for it, and when writing starts. In addition, apart from
the `config` file in the repo, all other file names have pseudo-random
names with a very very low probability of a collision. And even if a
file name is written again, the way the restic repo is structured this
just means that the same content is placed there again. Which is not a
problem, just not very efficient.

So, this commit relaxes the requirement to return an error when the file
in the backend already exists, which allows reducing the number of API
requests and thereby the latency for remote backends.

Alexander Neumann 5dc8d3588d GS: Use generic http transport
During the development of #1524 I discovered that the Google Cloud
Storage backend did not yet use the HTTP transport, so things such as
bandwidth limiting did not work. This commit does the necessary magic to
make the GS library use our HTTP transport.

Alexander Neumann f99c95c766 archiver: Fix intermediate index upload
A user discovered[1] that when the backup finishes during the upload of
an intermediate index, the upload is cancelled and the index never fully
saved, but the snapshot is saved and the backup finalizes without an
error. This lead to a situation where a snapshot references data that is
contained in the repo, but not referenced in any index, leading to
strange error messages.

This commit uses a dedicated context to signal the intermediate index
uploading routine to terminate after the last index has been uploaded.
This way, an upload running when the backup finishes is completed before
the routine terminates and the snapshot is saved.
