[pdm-devel] [PATCH datacenter-manager 0/2] validate remote hostname

[Shannon Sterz]

previously the endpoints list in the ui did not validate user input,
nor did the api when updating a remote. this could lead to an issue
where a user could configure a remote in a way that made it impossible
for pdm to connect to it. this series fixes that.

changes since v1:

* add validation to the correct place, thanks @ Dominik Csapak

Shannon Sterz (2):
  ui: node url list: validate list of endpoints
  api types: node url: validate hostname

[pdm-devel] [PATCH datacenter-manager 1/2] ui: node url list: validate list of endpoints

[Shannon Sterz]

otherwise user can manually edit these fields. when adding a remote
through a wizzard the api will return an error that the value doesn't
match the validation regex instantly. hence, there it is mostly a ux
issue.

when editing a remote, however, the api doesn't validate the url. so
adding, for a example a protocol (e.g. "https://") to the hostname/ip
field, will lead to connection errors when looking at the remote's
overview.

This requires a reference to compile for me:
     .schema(&HOST_OPTIONAL_PORT_SCHEMA)

[pdm-devel] [PATCH datacenter-manager 2/2] api types: node url: validate hostname

[Shannon Sterz]

otherwise, it is possible to set values via the api when updating a
remote that won't work. for example, adding a protocol like "https://"
to the beginning of a remote's hostname will break attempts at
connecting to it.
