.source_date_epoch ⇒ Object
Returns the value of Gem.source_date_epoch_string, as a Time object.
This is used throughout RubyGems for enabling reproducible builds.

.source_date_epoch_string ⇒ Object
If the SOURCE_DATE_EPOCH environment variable is set, returns it's value. Otherwise, returns the time that `Gem.source_date_epoch_string` was first called in the same format as SOURCE_DATE_EPOCH.
NOTE(@duckinator): The implementation is a tad weird because we want to:
1. Make builds reproducible by default, by having this function always
return the same result during a given run.
2. Allow changing ENV['SOURCE_DATE_EPOCH'] at runtime, since multiple
tests that set this variable will be run in a single process.
If you simplify this function and a lot of tests fail, that is likely due to #2 above.

.sources ⇒ Object
Returns an Array of sources to fetch remote gems from. Uses default_sources if the sources list is empty.

.sources=(new_sources) ⇒ Object
Need to be able to set the sources without calling Gem.sources.replace since that would cause an infinite loop.
DOC: This comment is not documentation about the method itself, it's more of a code comment about the implementation.

.try_activate(path) ⇒ Object
Try to activate a gem containing path
. Returns true if activation succeeded or wasn't needed because it was already activated. Returns false if it can't find the path in a gem.

.use_gemdeps(path = nil) ⇒ Object
Looks for a gem dependency file at path
and activates the gems in the file if found. If the file is not found an ArgumentError is raised.
If path
is not given the RUBYGEMS_GEMDEPS environment variable is used, but if no file is found no exception is raised.
If '-' is given for path
RubyGems searches up from the current working directory for gem dependency files (gem.deps.rb, Gemfile, Isolate) and activates the gems in the first one found.
You can run this automatically when rubygems starts. To enable, set the RUBYGEMS_GEMDEPS
environment variable to either the path of your gem dependencies file or “-” to auto-discover in parent directories.
NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control.
