134abbd82b rest: Use client for creating the repository
Before, creating a new repo via REST would use the defaut HTTP client,
which is not a problem unless the server uses HTTPS and a TLS
certificate which isn't signed by a CA in the system's CA store. In this
case, all commands work except the 'init' command, which fails with a
message like "invalid certificate".

41c8c946ba Fix chaining of credentials for minio-go
chaining failed because chaining provider
was only looking for subsequent credentials
provider after an error. Writer a new
chaining provider which proceeds to fetch
new credentials also under situations where
providers do not return but instead return
no keys at all.

3304b0fcf0 prevent deadlock in List() for B2 when b2.connections=1
This is a fix for the following situation (gh-1188):

List() grabs a semaphore token upon entry, starts a goroutine, and
does not release the token until the routine exits (via a defer).

The goroutine iterates over the results from ListCurrentObjects(),
sending them one at a time to a channel, where they are ultimately
processed by be.Load().

Since be.Load() also needs a token, this will result in deadlock if
b2.connections=1.

This fix changes List() so that the token is only held during the call
to ListCurrentObjects().

5b96885c6d Control progress rate with RESTIC_PROGRESS_FPS env
Add a RESTIC_PROGRESS_FPS environment variable to limit the interval
at which the progress indicator updates (allowed values: 1-60).

The default rate of 60 FPS can cause high terminal CPU load on some
systems, like iTerm2 on macOS with font anti-aliasing enabled.

Usage:

    RESTIC_PROGRESS_FPS=1 restic ...
    RESTIC_PROGRESS_FPS=60 restic ...

944fc857eb Fix failure to detect some legacy s3 repos
Sometimes s3 listobjects for a directory includes an entry for that
directory. The restic s3 backend doesn't expect that and returns
an error.

Symptom is:
  ReadDir: invalid key name restic/key/, removing prefix
     restic/key/ yielded empty string

I'm not sure when s3 does that; I'm unable to reproduce it myself.

But in any case, it seems correct to ignore that when it happens.

Fixes #1068

9fa4f5eb6b gs: disable resumable uploads
By default, the GCS Go packages have an internal "chunk size" of 8MB,
used for blob uploads.

Media().Do() will buffer a full 8MB from the io.Reader (or less if EOF
is reached) then write that full 8MB to the network all at once.

This behavior does not play nicely with --limit-upload, which only
limits the Reader passed to Media. While the long-term average upload
rate will be correctly limited, the actual network bandwidth will be
very spikey.

e.g., if an 8MB/s connection is limited to 1MB/s, Media().Do() will
spend 8s reading from the rate-limited reader (performing no network
requests), then 1s writing to the network at 8MB/s.

This is bad for network connections hurt by full-speed uploads,
particularly when writing 8MB will take several seconds.

Disable resumable uploads entirely by setting the chunk size to zero.
This causes the io.Reader to be passed further down the request stack,
where there is less (but still some) buffering.

My connection is around 1.5MB/s up, with nominal ~15ms ping times to
8.8.8.8.

Without this change, --limit-upload 1024 results in several seconds of
~200ms ping times (uploading), followed by several seconds of ~15ms ping
times (reading from rate-limited reader). A bandwidth monitor reports
this as several seconds of ~1.5MB/s followed by several seconds of
0.0MB/s.

With this change, --limit-upload 1024 results in ~20ms ping times and
the bandwidth monitor reports a constant ~1MB/s.

I've elected to make this change unconditional of --limit-upload because
the resumable uploads shouldn't be providing much benefit anyways, as
restic already uploads mostly small blobs and already has a retry
mechanism.

--limit-download is not affected by this problem, as Get().Download()
returns the real http.Response.Body without any internal buffering.

042adeb5d0 Refactor credentials management to support multiple mechanisms.
This PR adds the ability of chaining the credentials provider,
such that restic as a tool attempts to honor credentials from
multiple different ways.

Currently supported mechanisms are

 - static (user-provided)
 - IAM profile (only valid inside configured ec2 instances)
 - Standard AWS envs (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
 - Standard Minio envs (MINIO_ACCESS_KEY, MINIO_SECRET_KEY)

2133869127 cache: OS-specific cache directories
Windows, and to a lesser extent OS X, don't conform to XDG and have
their own preferred locations for caches.

On Windows, use %LOCALAPPDATA%/restic (i.e., ~/AppData/Local/restic). I
can't find authoritative documentation from Microsoft recommending
specifically which of %APPDATA%, %LOCALAPPDATA%, and %TEMP% should be
used for caches, but %LOCALAPPDATA% is where browsers store their
caches, so it seems like a good fit.

On OS X, use ~/Library/Caches/restic, which is recommended by the Apple
documentation. They do suggest using the application "bundle identifier"
as the base folder name, but restic doesn't have one, so I just used
"restic".

fa0be82da8 gs: allow backend creation without storage.buckets.get
If the service account used with restic does not have the
storage.buckets.get permission (in the "Storage Admin" role), Create
cannot use Get to determine if the bucket is accessible.

Rather than always trying to create the bucket on Get error, gracefully
fall back to assuming the bucket is accessible. If it is, restic init
will complete successfully. If it is not, it will fail on a later call.

Here is what init looks like now in different cases.

Service account without "Storage Admin":

Bucket exists and is accessible (this is the case that didn't work
before):

Service account with "Storage Admin":

Bucket exists and is accessible: Same

Bucket exists but is not accessible: Same. Previously this would fail
when Create tried to create the bucket. Now it fails when trying to
create the keys.

Bucket does not exist:

file is accessed again in the future.

fb9729fdb9 sftp: Allow password entry
This was a bit tricky: We start the ssh binary, but we want it to ignore
SIGINT. In contrast, restic itself should process SIGINT and clean up
properly. Before, we used `setsid()` to give the ssh process its own
process group, but that means it cannot prompt the user for a password
because the tty is gone.

So, now we're passing in two functions that ignore SIGINT just before
the ssh process is started and re-install it after start.

3541d06d07 repo: Split packers for tree and data
The code now bundles tree blobs and data blobs into different pack

trees. This is in preparation to adding a cache (#1040), because
tree-only pack files can easily be cached later on.

Resolve name collisions
2017-09-05 22:33:32 +02:00

83eb075e3a Resolve name collisions
At the moment when two items to be saved have the same directory name,
restic only saves the first one to the repo. Let's say we have a
structure like this:

    dir1
    └── subdir
        └── file
    dir2
    └── subdir
        └── file

When restic is run on `dir1/subdir` and `dir2/subdir`, it will only save
the first `subdir`:

    $ restic backup dir1/subdir dir2/subdir
    [...]

    $ restic ls -l latest
    drwxr-xr-x  1000   100      0 2017-08-27 20:56:39 /subdir
    -rw-r--r--  1000   100     17 2017-08-27 20:56:39 /subdir/file

That's obviously a bad thing, caused by an early decision to strip the
full path to the files/dirs to save and only leave the last directory.

This commit partly resolves this by handling colliding names and
resolving the conflicts. Restic will now append a counter to the file
(`-123`) until the conflict is resolved. So in the example above, we'll
end up with the following structure:

    $ restic ls -l latest
    drwxr-xr-x  1000   100      0 2017-08-27 20:56:39 /subdir
    -rw-r--r--  1000   100     17 2017-08-27 20:56:39 /subdir/file
    drwxr-xr-x  1000   100      0 2017-08-27 20:56:46 /subdir-1
    -rw-r--r--  1000   100     17 2017-08-27 20:56:46 /subdir-1/file

This partly addresses #549 and closes #1179.

At first I thought that the obvious correction would be to archive the
full path. But it turns out that collisions may still occur: Suppose you
have a file named `foo` in the current directory, and the parent directory
also contains a file `foo`. Archiving these with restic also causes a
collision, since restic strips the `../` from the first file:

    $ restic backup ../foo foo

This also happens with `tar`, which does not handle the collision and
will happily archive two files called `foo`.

So, the best way forward is to handle name collisions and archive the
whole path. The latter will be tackled in a separate PR.

92eb1cbffd filter: document recursive wildcards
Match/ChildMatch accept a ** pattern which is not noted in the doc

greedy (i.e., can 'foo/**/bar' match paths with additional intermediate
bar directories?).

Add a note to the doc string and add test cases for greedy matches.
