Up to 1s lag when invoking "fuck"

[MightyPork]

It worked really good before, but now when I mistype git command and use fuck, I get lag:

$ git brnahc
git: 'brnahc' is not a git command. See 'git --help'.

Did you mean this?
        branch
$ fuck
--- 1 second lag ---
git branch [enter/↑/↓/ctrl+c]
--- press enter ---
* dev
  master
  .....

I have version 3.0.

The alias is installed as follows:

$ alias fuck
alias fuck='eval $(thefuck $(fc -ln -1))'

Ideas what to try?

Here's also my $PATH if it matters

/home/ondra/.gem/ruby/2.2.0/bin:/home/ondra/GNUstep/Tools:
/usr/local/sbin:/usr/local/bin:/usr/bin:/opt/android-sdk/platform-tools:
/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:
/usr/bin/core_perl:/home/ondra/bin:/home/ondra/.composer/vendor/bin

I'm on Arch Linux (64bit) with python 3.4.3

Can you remove ~/.thefuck/.thefuck-cache and measure time again?

[MightyPork]

Small improvement, I tried "time fuck" and pressed ^C just when it appeared, and got 0.6s. So I think something like 0.5s. Maybe that's normal, not sure - I have SSD though, should be really fast...

[nvbn]

And can you post output of:

export THEFUCK_DEBUG=true
git br
fuck

?

[MightyPork]

Here it is:

I've changed the config file from default to:

#
# The default values are as follows. Uncomment and change to fit your needs.
# See https://github.com/nvbn/thefuck#settings for more information.
#

require_confirmation = False
# wait_command = 3
# rules = []
# no_colors = False

(also kinda weird that it says "The default values are as follows", when "require_confirmation = False" was in the file by default (commented out) and fuck used True...)

[MightyPork]

For the record, after deleting .bash_history, I get:

DEBUG: Trying rule: history; took: 0:00:00.093100
...
DEBUG: Total took: 0:00:00.331774

no not a very big improvement (if my assumption that it uses .bash_history is right)

[nvbn]

Thanks for the data.

(also kinda weird that it says "The default values are as follows", when "require_confirmation = False" was in the file by default (commented out) and fuck used True...)

It's because it was generated by the old version of app, like 1.xx.

When the file ~/.thefuck/settings.py already exists it's not regenerated/updated. I'm gonna work on that, merge/update it with new/changed confs.
