[pbs-devel] [PATCH proxmox{, -backup}/widget-toolkit v4 0/7] fix #5463: add optional consent banner before login

[pbs-devel] [PATCH proxmox{, -backup}/widget-toolkit v4 0/7] fix #5463: add optional consent banner before login

[Gabriel Goller]

The consent text is stored in the node.cfg config file and is encoded
using base64. This allows us to support multi-line strings and special
characters. To easily edit the text a new edit-field called
ProxmoxTextAreaField has been introduced. It supports editing and saving
multi-line text and converting it to its base64 representation.

The same implementation will be ported to pve and eventually pmg in 
the foreseeable future.

v4:
 - rebase

v3, thanks @Dominik, @Thomas:
 - store text with base64 instead of URI-encoding
 - improve content popup sizing
 - support markdown

v2, thanks @Thomas, @Dominik:
 - remove consent.txt file, move to node.cfg config
 - add ui option to insert consent text
 - encode text with encodeURI/decodeURI

v1, thanks @Dominik:
 - embed consent text into index.html file instead of extra api request
 - removed decline button
 - added alwaysOnTop property to popup

[pbs-devel] [PATCH widget-toolkit v4 1/7] utils: add base64 conversion helper

[Gabriel Goller]

Add helper functions to convert from a utf8 string to a base64 string
and vice-versa. Using the TextEncoder/TextDecoder we can support unicode
such as emojis as well [0].

[pbs-devel] [PATCH widget-toolkit v4 3/7] form: add support for multiline textarea

[Gabriel Goller]

This adds support for a editable multiline textarea in the ObjectGrid.
Now we can add a textarea row, which will open a textarea popup, and
encode the multi-line text into an base64 string (with utf8 support).

[pbs-devel] [PATCH proxmox v4 4/7] rest-server: add custom handlebars escape fn

[Gabriel Goller]

Add a custom handlebars escape function. It's nearly identical to the
default `html_escape` fn [0], but it does not escape the '='. This is
needed to support base64 encoded values.

FWIW this could be a bit shorter by using map (which typed arrays
also support [0]):

        const escapedString = bytes.map(b => String.fromCodePoint(b)).join('');

But for that we really need no new revision.

applied, with the indentation mess in the init function a bit improved, thanks!

btw. onnlineHelp link would be great, IMO it's a bit of a confusing setting as
is.

Will send two follow-up patches with this one and the small nit on the first
commit!

I just tried this and it sadly doesn't work. `String.fromCodePoint`
returns a string, which can't be stored in the `Uint8Array` which is `bytes`.

You are right, sorry for the misdirection.
One would need the non-typed array method for that, i.e.:

var escapedString = Array.prototype.map.call(bytes, b => String.fromCodePoint(b)).join('');

Which really is not nicer than what you did, so let's go with that.
