Add a new IP address search page at /ip_addresses. Replaces the old
search page at /moderator/ip_addrs.
On user profile pages, show the user's last known IP to mods. Also add
search links for finding other IPs or accounts associated with the user.
IP address search uses a big UNION ALL statement to merge IP addresses
across various tables into a single view. This makes searching easier,
but is known to timeout in certain cases.
Fixes#4207 (the new IP search page supports searching by subnet).
This gem uses a native extension that requires a C++ compiler to build.
Removing this gem removes the need to have a C++ toolchain to install Danbooru.
DText was changed so that the .dtext-external-link class is now applied to all external links.
Previously it applied only to named links (ex: "google":[http://www.google.com]), not bare
links (ex: http://www.google.com).
Fixes issue with newrelic failing to set up rake instrumentation:
ERROR : Error while detecting rake_instrumentation:
ERROR : NameError: uninitialized constant Rake::VERSION
Foreman is unmaintained and locked to a really old version of thor,
which prevents upgrading to Rails 6.
The Procfile can still be used by manually installing Foreman with
`gem install foreman`. This is what Foreman's README recommends anyway.
Upgrade procedure:
$ echo 2.6.3 > .ruby-version
# upgrade ruby-build to know about the latest ruby versions.
# see also: github.com/rkh/rbenv-update
$ cd ~/.rbenv/plugins/ruby-build && git pull
# install the version of ruby specified in .ruby-version.
# see also: github.com/capistrano/rbenv/issues/83
$ rbenv install --skip-existing
# update the shell to use the latest version of ruby by default.
$ rbenv global 2.6.3
# update rubygems and bundler
$ gem update --system
# update the lockfile to use the latest version of bundler
$ bundle update --bundler
