convert.c: refactor crlf_action
Refactor the determination and usage of crlf_action. Today, when no "crlf" attribute are set on a file, crlf_action is set to CRLF_GUESS. Use CRLF_UNDEFINED instead, and search for "text" or "eol" as before. After searching for line ending attributes, save the value in struct conv_attrs.crlf_action attr_action, so that get_convert_attr_ascii() is able report the attributes. Replace the old CRLF_GUESS usage: CRLF_GUESS && core.autocrlf=true -> CRLF_AUTO_CRLF CRLF_GUESS && core.autocrlf=false -> CRLF_BINARY CRLF_GUESS && core.autocrlf=input -> CRLF_AUTO_INPUT Save the action in conv_attrs.crlf_action (as before) and change all callers. Make more clear, what is what, by defining: - CRLF_UNDEFINED : No attributes set. Temparally used, until core.autocrlf and core.eol is evaluated and one of CRLF_BINARY, CRLF_AUTO_INPUT or CRLF_AUTO_CRLF is selected - CRLF_BINARY : No processing of line endings. - CRLF_TEXT : attribute "text" is set, line endings are processed. - CRLF_TEXT_INPUT: attribute "input" or "eol=lf" is set. This implies text. - CRLF_TEXT_CRLF : attribute "eol=crlf" is set. This implies text. - CRLF_AUTO : attribute "auto" is set. - CRLF_AUTO_INPUT: core.autocrlf=input (no attributes) - CRLF_AUTO_CRLF : core.autocrlf=true (no attributes) Signed-off-by: Torsten Bögershausen <tboegi@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
