Net::SCP::Error: SCP No such file or directory

[map7]

When I run capistrano-db-tasks using capistrano 3.7.0 to pull my database with 'cap production db:pull --trace' I get the following error;

Net::SCP::Error: SCP did not finish successfully (1): scp: ./db/vinocellar_production_2

The work around is to set my db_dump_dir to "/tmp" instead of "./db" as it cannot find this. I would assume that this ./db directory should be relative to my Rails.root path on the production server but it doesn't seem to be working.

Still broken in 0.6

Just wanted to let you know that i had the same issue. Didn't look further in it as the workaround with the tmp directory worked fine.

[itolosa]

It worked fine by specifying the entire path:

# deploy.rb
set :db_dump_dir, -> { File.join(current_path, 'db') }

[numbata]

@map7 do you have _APP_PATH_/db directory? @itolosa can you check this branch https://github.com/numbata/capistrano-db-tasks/tree/issues/104/db_dump_dir_fix ?

[itolosa]

@numbata I think the error here is to assume that ./ always points to the project directory, and I think is rancid to replace ./ to the current_path. Maybe a Readme update would be great to avoid more confusions

This even doesn't seem a problem due to a change in THIS repository. I upgraded some unrelated gems in the bundle when I suddenly got this error. I wasn't able to restore the previous behavior because I only discovered this problem later in development. But at least reverting capistrano itself to the last known working version didn't help, neither did reverting sshkit, net-scp, or capistrano-db-tasks fix the problem. So something else must have changed behavior.

But the problem is probably still within THIS repo as it depends on some non-defined defaults when it shouldn't (e.g., the working directory).
