convert.c: ident + core.autocrlf didn't work

2016-04-25T19:12:03Z

When the ident attributes is set, get_stream_filter() did not obey core.autocrlf=true, and the file was checked out with LF. Change the rule when a streaming filter can be used: - if an external filter is specified, don't use a stream filter. - if the worktree eol is CRLF and "auto" is active, don't use a stream filter. - Otherwise the stream filter can be used. Add test cases in t0027. Signed-off-by: Torsten Bögershausen Signed-off-by: Junio C Hamano

convert.c: correct attr_action()

2016-02-23T20:53:15Z

df747b81 (convert.c: refactor crlf_action, 2016-02-10) introduced a bug to "git ls-files --eol". The "text" attribute was shown as "text eol=lf" or "text eol=crlf", depending on core.autocrlf or core.eol. Correct this and add test cases in t0027.

convert.c: simplify text_stat

2016-02-10T23:54:20Z

Simplify the statistics: lonecr counts the CR which is not followed by a LF, lonelf counts the LF which is not preceded by a CR, crlf counts CRLF combinations. This simplifies the evaluation of the statistics. Signed-off-by: Torsten Bögershausen Signed-off-by: Junio C Hamano

convert.c: refactor crlf_action

2016-02-10T23:53:35Z

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 Signed-off-by: Junio C Hamano

Merge branch 'ls/clean-smudge-override-in-config'

2016-02-10T22:20:07Z

Clean/smudge filters defined in a configuration file of lower precedence can now be overridden to be a pass-through no-op by setting the variable to an empty string. * ls/clean-smudge-override-in-config: convert: treat an empty string for clean/smudge filters as "cat"

convert.c: use text_eol_is_crlf()

2016-02-08T18:02:12Z

Add a helper function to find out, which line endings text files should get at checkout, depending on core.autocrlf and core.eol configuration variables. Signed-off-by: Torsten Bögershausen Signed-off-by: Junio C Hamano

convert.c: remove input_crlf_action()

2016-02-08T18:01:40Z

Integrate the code of input_crlf_action() into convert_attrs(), so that ca.crlf_action is always valid after calling convert_attrs(). Keep a copy of crlf_action in attr_action, this is needed for get_convert_attr_ascii(). Remove eol_attr from struct conv_attrs, as it is now used temporally.

convert.c: remove unused parameter 'path'

convert: treat an empty string for clean/smudge filters as "cat"

2016-01-29T19:04:27Z

Once a lower-priority configuration file defines a clean or smudge filter, there is no convenient way to override it to produce as-is output. Even though the configuration mechanism implements "the last one wins" semantics, you cannot set them to an empty string and expect them to work, as apply_filter() would try to run the empty string as an external command and fail. The conversion is not done, but the function would still report a failure to convert. Even though resetting the variable to "cat" (i.e. pass the data back as-is and report success) is an obvious and a viable way to solve this, it is wasteful to spawn an external process just as a workaround. Instead, teach apply_filter() to treat an empty string as a no-op filter that always returns successfully its input as-is without conversion.
