@return [String] a string suitable for debugging
If the stream begins with a BOM (byte order marker), consumes the BOM and sets the external encoding accordingly; returns the result encoding if found, or nil
otherwise:
File.write('t.tmp', "\u{FEFF}abc") io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => #<Encoding:UTF-8> io.close File.write('t.tmp', 'abc') io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => nil io.close
Raises an exception if the stream is not binmode or its encoding has already been set.
Returns the last win32 socket Error
of the current executing Thread
or nil if none
Sets the last win32 socket Error
of the current executing Thread
to error
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.
