influxdb-cli does not follow xdg base directory specification

[pavelskipenes]

TLDR; save history to $HOME/.local/state/influx/history if $XDG_STATE_HOME is not defined otherwise to $XDG_STATE_HOME/influx/history instead of $HOME/influx_history.

From XDG Base Directory Specification:

The XDG Base Directory Specification is based on the following concepts:

• There is a single base directory relative to which user-specific state data should be written. This directory is defined by the environment variable $XDG_STATE_HOME.

The $XDG_STATE_HOME contains state data that should persist between (application) restarts, but that is not important or portable enough to the user that it should be stored in $XDG_DATA_HOME. It may contain:

• actions history (logs, history, recently used files, …)

Looks like relevant lines are around here:

influx-cli/clients/v1_shell/v1_shell.go

Line 153 in 3a2e139

c.historyFilePath = filepath.Join(historyDir, ".influx_history")
