This commit adds SSE-C (Server-Side Encryption - Customer) support to
the B2 native backend. The server uses a customer provided AES-256 key
to encrypt the files when you upload them to the bucket, and then it
discards your key from the servers RAM after you're done uploading.
The option names and descriptions are based off the S3 backend
implementation as the way S3 and B2 does SSE-C is pretty similar.
Fixes#6585
Give users a way to explicitly acknowledge that pipes, sockets and block
devices are to be ignored without warnings.
This follows the precedent set in commit 6152bab28 (local: add
--skip-links to suppress symlink warnings, 2017-07-21) for ignoring
warnings about symlinks.
* Adds "aix/ppc64" to the cross-compile target list.
* Including AIX in the build tag of "metadata_other.go".
* Excluding AIX from the main ncdu build tags.
* Marking AIX as an unsupported platform for ncdu.
* Excluding AIX from the fallback redirect implementation.
* Excluding AIX from unix build tags to avoid undefined unix.WNOHANG.
We were seeing a (non-fatal) error in our logs:
```
Failed to seek log file to end: seek /proc/1/fd/1: illegal seek
```
Because we open the log file with O_APPEND,
we don't need to manually seek to the end.
As https://pkg.go.dev/os#File.Seek also confirms
that the behavior of `Seek` is not specified
if the file has been opened with O_APPEND,
remove the `Seek` call.
Before this change, you had to modify a fragile data-structure
containing all providers. This often led to things being out of order,
duplicates and conflicts whilst merging. As well as the changes for
one provider being in different places across the file.
After this change, new providers are defined in an easy to edit YAML file,
one per provider.
The config output has been tested before and after for all providers
and any changes are cosmetic only.
Before this change --no-traverse was calling NewObject on directories
(where it would always fail) as well as files. This was very
noticeable when doing syncs with --max-age which were only
transferring a small number of objects. This should have been very
quick, but the NewObject calls for each directory slowed the sync down
a lot.
This changes replaces the check to see if the source entry is an
Object that got missed out from this commit:
