XDG variables / config-settings confusion

[Baerbeisser]

pikaur -Sy

Prerequisites:

environment set to:
XDG_CACHE_HOME=$HOME/.local/tmp
XDG_DATA_HOME=$HOME/.local/data

Description:

every time you run pikaur,

cachepath = $HOME/.cache
datapath = $HOME/.local/share

gets addded to pikaur.conf independ of your XDG variables and it then uses cachepath for cache.
Curiously, it then still uses ~/.local/data/pikaur for aur_repos.

So, in summary:

• XDG_CACHE_HOME gets ignored for config
• • cachepath in config gets used
• XDG_DATA_HOME gets ignored for config
• • but used for repo backups

@samuel-jimenez , please communicate with @Baerbeisser how to fix that, otherwise i'll have to unmerge your PR (#796)

[samuel-jimenez]

The order of resolution is:

1. Command line options (--xdg-cache-home)
2. Environment variables (XDG_CACHE_HOME)
3. Config setting (cachepath = ..)

So the config setting should not matter if an environment variable is set.

Part of the pikaur operation is to call itself with sudo and command line options. In this step, the incorrect cachepath is used.

I will look around to find a fix.
