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.
In #1590, it was mentioned that while lines read from exclude files via
`--exclude-file` have leading and trailing spaces stripped, this is not
the case for lines read via `--files-from`. This commit fixes that,
spaces are always stripped.
This commit removes the bandwidth displayed during backup process. It is
misleading and seldomly correct, because it's neither the "read
bandwidth" (only for the very first backup) nor the "upload bandwidth".
Many users are confused about (and rightly so), c.f. #1581, #1033, #1591
We'll eventually replace this display with something more relevant when
#1494 is done.
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.
When looking up a blob in the master index, with several
indexes present in the master index, a significant amount of time
is spent generating errors for each failed lookup. However, these
errors are often used to check if a blob is present, but the contents
are not inspected making the overhead of the error not useful.
Instead, change Index.Lookup (and Index.LookupSize) to instead return
a boolean denoting if the blob was found instead of an error. Also change
all the calls to these functions to handle the new function signature.

Is seems that #1307 is similar to #1087, which describes a comparable
observation on Apple's new filesystem. #1389 Has been committed and
fixes the problem on Darwin.
Although I'm not sure if the root cause of the issue is the same the
solution is similar for OpenBSD, and leverages #1389.
On Darwin, allow a 1μs difference in restored timestamps, because
macOS <10.13 cannot restore with nanosecond precision and the current
version of Go (1.9.2) does not yet support the new syscall required
for this. (#1087#1389)
Add --last flag to snapshots command to only show the last entry for any
(hostname, paths) combination.
This makes it easier to check when various paths were last backed up.
Backup was choosing a parent snapshot that had the same tags, which
makes backup unnecessarily slow when there are newer snapshots with
different tags.
There's no reason parent has to have the same tags.
This change makes backup choose the newest snapshot instead.
This removes the conditions that checks if the password is supplied
through environment variable or file and outputs password is successful
on terminal and when --quiet is not supplied.
This adds some feedback when entering the password on the command line.
When the password is entered and supplied through stdin (and stdout is a
terminal) then the a message saying `password is correct` if correct is
printed.
This adds additional output to the check command when no errors were
found. It means that when all checks have been completed, the following
output is displayed:
No errors were found
The output is added to make sure that it is easier to understand that no
errors were found.
Full example output:
Create exclusive lock for repository
Load indexes
Check all packs
Check snapshots, trees and blobs
No errors were found
This commit removes the `manpages` and `autocomplet` commands and
replaces them with the more generic `generate` command. Also, zsh
completion file support was added.
This commits adds rudimentary support for a cache directory, enabled by
default. The cache directory is created if it does not exist. The cache
is used if there's anything in it, newly created snapshot and index
files are written to the cache automatically.
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.
The option is named --exclude-if-present and accepts a parameter
filename[:content]. Directories are excluded and their contents is not
backed up if they contain a file with the specified name and,
optionally, that starts with the specified content. The tagfile itself
is never excluded.
There is also a shortcut --exclude-caches that works in the same way as
the likewise-named option of tar(1): Directories are recognized as cache
if they contain a file named "CACHEDIR.TAG.
Closes #317.
By default (i.e., without profile.NoShutdownHook), profile.Start listens
for SIGINT and will stop the profile and call os.Exit(0).
restic already listens for SIGINT and runs its own cleanup handlers
before calling os.Exit(0).
As is, these handlers are racing when an interrupt occurs, and in my
experience, restic tends to win the race, resulting in an unusable
profile.
Eliminate the race and properly stop profiles on interrupt by disabling
package profile's signal handler and instead stop the profile in a
restic cleanup handler.
An exclude filter is basically a 'wildcard but foo', so even if a
childMayMatch, other children of a dir may not, therefore childMayMatch
does not matter, but we should not go down unless the dir is selected
for restore.
This improves restore performance by several orders of magniture by not
going through the whole tree recursively when we can anticipate that no
match will ever occur.
