[pve-devel] [PATCH-SEREIES v3 common/guest-common/manager] add protected and notes-template parameters for vzdump

[Fabian Ebner]

Introduce 'protected' to automatically mark a backup as protected
upon completion, and 'notes-template' to generate notes from a
template string with certain variables.

Add both to the UI for manual backups and add 'notes-template' to the
UI for backup jobs.


Changes from v2:
    * Dropped already applied half of the series.
    * Switch to {{var}} syntax instead of $VAR.
    * Add a patch to have doc generation handle the braces.

[pve-devel] [PATCH v3 common 1/1] REST handler: get property description: escape curly braces for asciidoc

[Fabian Ebner]

Text enclosed in unescaped curly braces will be interpreted as an
attribute reference breaking and e.g. lead to the description not
showing up at all a generated man page further down the line.

New in v3.

Tried out various uses of curly braces and seems to work for man
pages, HTML doc and API-viewer.

[pve-devel] [PATCH v3 guest-common 1/1] vzdump: schema: add 'notes-template' and 'protected' properties

[Fabian Ebner]

In command_line(), notes are printed, quoted, but otherwise as is,
which is a bit ugly for multi-line notes. But it is part of the
commandline, so print it.

Arguably, a warning from failing to set notes is not very visible, but
I didn't want to make it a full-blown error.
