Ar an cúigiú lá is fiche de mí Deireadh Fómhair, scríobh Vin Shelton: Okay, using automatic-conversion as the coding system there was wrong in the original code; Installation-string should not be stored as binary. Here’s a patch that works out its encoding, decodes it using that encoding at dump time, and eliminates your error. Can anyone tell me why version.el was dumped uncompiled? I would search the mail archives but, you know ... My patch of 18087.28114.645429.344798(a)parhasard.net was also based on the logic that byte-compiling it won’t make a difference; I didn’t get to committing it. This patch requires that it be compiled in passing, since init-locale-at-early-startup (which works out the native coding system) is called at byte-compile time during the build, but not at dump time. lisp/ChangeLog addition: 2007-10-26 Aidan Kehoe <kehoea(a)parhasard.net&gt; * mule/general-late.el: Now that all the dumped coding systems are available, decode Installation-string using the value for Installation-file-coding-system at dump time. 2007-10-26 Aidan Kehoe <kehoea(a)parhasard.net&gt; * dumped-lisp.el (preloaded-file-list): Allow version.el to be compiled. * help.el (describe-installation): Use and-boundp instead of (and (boundp ...); don't decode Installation-string. Call #'error with a DATUM arg. * loadup.el: * loadup.el (Installation-string): Removed. Moved to version.el. * loadup.el (really-early-error-handler): Move the initialization of Installation-string to version.el too. * update-elc-2.el (update-elc-ignored-files): * update-elc-2.el (batch-update-elc-2): Remove version.el from the ignored files; if Mule is available, always recompile it, since Installation-file-coding-system depends on relatively complex Mule code. * update-elc.el (unbytecompiled-lisp-files): Remove version.el. * version.el: * version.el (Installation-file-coding-system): New. Variable reflecting the native coding system at build time, to better work out Installation-string. * version.el (Installation-string): New. Moved from loadup.el; documented in more detail.
