Description Jan Psota 2020-03-21 01:46:22 UTC
...because they can include passwords.

I use PORTAGE_BINHOST=ftp://getbin:password@host
and something similar for GENTOO_MIRRORS.

Comment 2 Zac Medico gentoo-dev 2020-03-22 21:59:08 UTC
In addition to the emerge --info patch, we'll need another patch to fix the _hide_url_passwd function to replace all occurrences, since GENTOO_MIRRORS and PORTAGE_BINHOST may contain multiple values:

    _hide_url_passwd: replace all occurrences (bug 713726)
    
    Adjust the regular expression to avoid overly-greedy .+ groups,
    so that is will properly replace all occurrences, as necessary
    for the purposes of bug 713726 since PORTAGE_BINHOST may contain
    multiple values.

I see "*password*" now :-)
...but are you sure, that it is a better way than completely
filtering out variables that may contain authorisation info?

Woo!

This is the same solution used for ensuring logs are sanitised.

I went for your approach at first but it's possible that these variables could be useful for debugging. If you know you're using credentials in make.conf, it's worth checking it over before you share it.

I mean, some warning on --info could be considered, but IMO this would just be noise given this is quite a rare situation.

It filters out anything which the standard URI format for password, so we should be good... what's concerning you?
