Fix some bugs in load-history construction, built-in symbol file names. lib-src/ChangeLog addition: 2008-12-27 Aidan Kehoe <kehoea@parhasard.net> * make-docfile.c (main): Allow more than one -d argument, followed by a directory to change to. (put_filename): Don't strip directory information; with previous change, allows retrieval of Lisp function and variable origin files from #'built-in-symbol-file relative to lisp-directory. (scan_lisp_file): Don't add an extraneous newline after the file name, put_filename has added the newline already. lisp/ChangeLog addition: 2008-12-27 Aidan Kehoe <kehoea@parhasard.net> * loadup.el (load-history): Add the contents of current-load-list to load-history before clearing it. Move the variable declarations earlier in the file to a format understood by make-docfile.c. * custom.el (custom-declare-variable): Add the variable's symbol to the current file's load history entry correctly, don't use a cons. Eliminate a comment that we don't need to worry about, we don't need to check the `initialized' C variable in Lisp. * bytecomp.el (byte-compile-output-file-form): Merge Andreas Schwab's pre-GPLv3 GNU change of 19970831 here; treat #'custom-declare-variable correctly, generating the docstrings in a format understood by make-docfile.c. * loadhist.el (symbol-file): Correct behaviour for checking autoloaded macros and functions when supplied with a TYPE argument. Accept fully-qualified paths from #'built-in-symbol-file; if a path is not fully-qualified, return it relative to lisp-directory if the filename corresponds to a Lisp file, and relative to (concat source-directory "/src/") otherwise. * make-docfile.el (preloaded-file-list): Rationalise some let bindings a little. Use the "-d" argument to make-docfile.c to supply Lisp paths relative to lisp-directory, not absolutely. Add in loadup.el explicitly to the list of files to be processed by make-docfile.c--it doesn't make sense to add it to preloaded-file-list, since that is used for purposes of byte-compilation too. src/ChangeLog addition: 2008-12-27 Aidan Kehoe <kehoea@parhasard.net> * doc.c (Fbuilt_in_symbol_file): Return a subr's filename immediately if we've found it. Check for compiled function and compiled macro docstrings in DOC too, and return them if they exist. The branch of the if statement focused on functions may have executed, but we may still want to check variable bindings; an else clause isn't appropriate.
