I am busy changing the world

For couple years, users could not upload files into our Redmine instance when creating or updating issues (or tickets). We ignored it because most of the tickets were created from the email pulling task (IMAP) and the attachments were created just fine. But when we developed an external tool to manipulate issues with attachment, I think it's time to seriously looking at the problem and fix it. Here is the command we try (upload file using Redmine's Rest API): # curl 'http://myredmine.com/uploads.json' -X POST -H 'X-Redmine-API-Key: <myapikey>' -H 'Content-Type: application/octet-stream' --data-binary "@myfile.png" and errors (/var/log/redmine/default/production.log): ...

After we upgraded our gitlab server to v7.8 from v6.9 , we could not push code to it and always got this error: ... remote: /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/shared_helpers.rb:2:in `require': no such file to load -- rubygems (LoadError) remote:         from /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/shared_helpers.rb:2 remote:         from /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/setup.rb:1:in `require' remote:         from /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/setup.rb:1 To http://our.repo.url/myusername/my-project.git  !

Yesterday, I was trying to open the rails console of my gitlab server (gitlab v6.9.2, Ubuntu 12.04) to reset the admin password by the following command: $ cd /home/git/gitlab $ sudo -u git -H bundle exec rails console production But it raised this error: ... `require': no such file to load -- readline (LoadError) ... After a while, I fixed it by ( DO NOT MODIFY THE GEMFILE ): 1. Install readline dev packages: $ sudo apt-get install libreadline-dev 2. Recompile or upgrade ruby to v2.1: Note: The use of Ruby version managers such as RVM, rbenv or chruby with GitLab in production frequently leads to hard to diagnose problems. For example, GitLab Shell is called from OpenSSH and having a version manager can prevent pushing and pulling over SSH. Version managers are not supported and we strongly advise everyone to follow the instructions below to use a system Ruby. Install the required packages to compile ruby: $ sudo apt-get install -y build-essential zlib1g-de...

I found this setup is pretty helpful when working with Rails projects in Ubuntu (it's 14.04 in this case): Add these lines at the end of ~/.bashrc : export GEM_HOME=$HOME/ruby/gems export GEM_PATH=$GEM_HOME:/lib/ruby/gems/1.9.3 export GEM_CACHE=$GEM_HOME/cache export PATH=$PATH:$HOME/ruby/gems/bin To get affected right away: $ source ~/.bashrc
