Backport #5311: PStore fails to save data when default encodings are set

• Status: Closed
• Assignee: yugui (Yuki Sonoda)

[camerooni (Cameron Pope)]

When PStore opens its data files, it does so using the File::BINARY flag, which ensures that Windows will not do cr-lf conversions, but it does not ensure that file#external_encoding is ASCII_8BIT (Binary). That means that under certain circumstances (when Encoding.internal_encoding is defined) that PStore will sometimes raise errors when writing to disk because Marshal.dump will emit a byte sequence that is not valid with the file's external encoding.

To illustrate, I've submitted a patch that contains a test that fails in Ruby 1.9.x, but passes with the minor change to PStore: to specify external_encoding when opening its data files.
