Check for spaces or duplicate names in server config keys.
Since server config keys are case insensitive,
a setting like
```
{
compression = "yes";
Compression = "no";
}
```
would lead to an ambiguous configuration.
`tsm-client` uses a global configuration
file that must contain coordinates for each
server that it is supposed to contact.
This configuration consists of text
lines with key-value pairs.
In the NixOS module, these servers may be declared
with an attribute set, where the attribute name
defines an alias for the server, and the value
is again an attribute set with the settings for
the respective server.
This is organized as an option of type `attrsOf submodule...`.
Before this commit:
Important settings have their own option within
the submodule. For everything else, there is
the "catch-all" option `extraConfig` that may
be used to declare any key-value pairs.
There is also `text` that can be used to
add arbitrary text to each server's
section in the global config file.
After this commit:
`extraConfig` and `text` are gone,
the attribute names and values of each server's attribute
set are translated directly into key-value pairs,
with the following notable rules:
* Lists are translated into multiple lines
with the same key, as such is permitted by
the software for certain keys.
* `null` may be used to override/shadow a value that
is defined elsewhere and hides the corresponding key.
Those "important settings" that have previously been
defined as dedicated options are still defined as such,
but they have been renamed to match their
corresponding key names in the configuration file.
There is a notable exception:
"Our" boolean option `genPasswd` influences the "real"
option `passwordaccess', but the latter one is
uncomfortable to use and might lead
to undesirable outcome if used the wrong way.
So it seems advisable to keep the boolean option
and the warning in its description.
To this end, the value of `getPasswd` itself is
later filtered out when the config file is generated.
The tsm-backup service module and the vm test are adapted.
Migration code will be added in a separate
commit to permit easy reversal later, when the
migration code is no longer deemed necessary.
With the tsm-client 8.1.19.0 release,
IBM renamed the product brand from
"IBM Spectrum Protect" to "IBM Storage Protect":
https://www.ibm.com/support/pages/node/6964770 .
The package already got updated in commits
5ff5b2ae4c and
a4b7a62532 .
The commit at hand updates the modules accordingly.
Provide a NixOS module for the [built-in Anki Sync
Server](https://docs.ankiweb.net/sync-server.html) included in recent
versions of Anki. This supersedes the `ankisyncd` module, but we should
keep that for now because `ankisyncd` supports older versions of Anki
clients than this module.
SnapRAID has a feature where you can specify "split" parity files. This
is useful when you're using 16tb or bigger ext4-formatted disks for
parity. ext4 doesn't support files bigger than 16tb so this "split
parity file" can be used to specify two parity files on a single parity
disk and SnapRAID will automatically use the subsequent file when the current
cannot grow anymore (hits 16TB). You specify these split parity files by
separating them with commas in the "parity" config option. This
mostly already works except when it comes to the scheduled systemd sync
job where it specifies ReadWritePaths. If you specify a parity with
multiple files you'll get an error when the systemd job runs: Failed to
set up mount namespacing:
/run/systemd/unit-root/mnt/parity1/snapraid1.parity,/mnt/parity1/snapraid2.parity: No such file or directory
Essentially, when the parity file paths are passed into ReadWritePaths,
they're always treated as a single path. This change makes sure to
split the paths if they contain a comma.
The big concern for this change is if it would break users who have
commas in their actual parity file paths. This won't be an issue because SnapRAID
itself blindly splits on commas for parity files, so legitimate commas in a parity
file path wouldn't work in SnapRAID anyway. See here:
