Question

I’m looking for a way to make --insecure option the default one for any hg \ TortoiseHg command.

Please don’t write this is a bad practice – I aware about possible risks and consider they’re fully acceptable.

Answer 1

Setting cacerts in the [web] section to the empty string looks to be the same thing. From the source:

if cmdoptions.get('insecure', False):
    ui.setconfig('web', 'cacerts', '!', '--insecure')

which the wiki confirms:

Sometimes it may be expedient to
disable security checks, for instance
when dealing with hosts with
self-signed certificates. This can be
done by disabling the CA certificate
configuration on the command line:

hg push –config web.cacerts=
https://self-signed-host/repo

So putting cacerts=! in the [web] section of your global hgrc (/etc/mercurial/hgrc on linux-likes) will get you there.
