This allows creating multiple repositories with identical chunker
parameters which is required for working deduplication when copying
snapshots between different repositories.
The standard UNIX-style ordering of command-line arguments places
optional flags before other positional arguments. All of restic's
commands support this ordering, but some of the usage strings showed the
flags after the positional arguments (which restic also parses just
fine). This change updates the doc strings to reflect the standard
ordering.
Because the `restic help` command comes directly from Cobra, there does
not appear to be a way to update the argument ordering in its usage
string, so it maintains the non-standard ordering (positional arguments
before optional flags).
In the Google Cloud Storage backend, support specifying access tokens
directly, as an alternative to a credentials file. This is useful when
restic is used non-interactively by some other program that is already
authenticated and eliminates the need to store long lived credentials.
The access token is specified in the GOOGLE_ACCESS_TOKEN environment
variable and takes precedence over GOOGLE_APPLICATION_CREDENTIALS.
The backup command used to return a zero exit code as long as a snapshot
could be created successfully, even if some of the source files could not
be read (in which case the snapshot would contain the rest of the files).
This made it hard for automation/scripts to detect failures/incomplete
backups by looking at the exit code. Restic now returns the following exit
codes for the backup command:
- 0 when the command was successful
- 1 when there was a fatal error (no snapshot created)
- 3 when some source data could not be read (incomplete snapshot created)
Changes proposed in #2763:
- Adding `RESTIC_CACHE_DIR` environment variables (introduced in #2425 for Unix and #2607 for Mac, Win).
- Adding used system-wide environment variables with links to the corresponding section.
That site might not have supported https:// when those links were
originally added. It does now.
Also dropping the _spec.html_ ending of the url, there being a `<link
rel="canonical" ...>` tag suggesting that that no longer being the
preferred address.
On Linux CIFS (SMB) seems to be incompatible with the async preemption
implementation of Go 1.14. CIFS seems not to restart syscalls (open,
read, chmod, readdir, ...) as expected by Go, which sets SA_RESTART for
its signal handler to have syscalls restarted automatically. This leads
to Go passing up lots of EINTR return codes to restic.
See https://github.com/restic/restic/issues/2659 for a detailed explanation.
The favicon on restic.readthedocs.io still contained the old
superman-style logo.
This changes it to the 32x32 gopher icon also used on https://forum.restic.net/ ,
just converted to .ico using Gimp.
Tested by building the documentation and opening index.html in Chrome.
The new favicon looks fine.
