UI, a small change, shows "130 common lines(too big)" and can not expand the content.

[Yingchun Li]

Hi,

    There is a small change, but when show the diff, the diff view shows

"130 common lines(too big)", and also can not expand the contents.

    

     git show --stat shows:

         path/of/myrepo/coex_cfg_best1607.h | 3 +++
         1 file changed, 3 insertions(+)

     The file itself is also not big, the size is 5927bytes.

      I did some tests:

      1, recreate the change, using the some original file and updated file, can not reproduce.

       2, recreate the change on another server, can not reproduce.

       3, open the broser's develop tools, it shows:

        "coex_cfg_best1607.h:1 The resource http://myserver/changes/?q=change:300424 was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate `as` value and it is preloaded intentionally."

       4, also check the server log, there are no related errors.

       gerrit version is 3.12.3, and the chrome broswer is latest version.

       Please give some advice, thanks a lot.

Br,

Yingchun

Oh, from the setting ->"Diff Preferences", if the 'ignore Whitespace' is not default "None", and select any of "Trailing", "Leading & Trailing", or "All", then the contents can be showed.

Thanks.

But it is still very strange, because there is no any trialing white space on the changed lines, 

in fact, there is no any trailing white space in the whole file.

Well, then it would be single line ;) 

So I guess this is a line-ending problem ( \r\n (windows ) vs. \n  (linux) ).

I remember it as if we have solved similar issues at $DAY_JOB by adding local hooks to windows users that eliminate all line-ending corner-cases.
Commit: "\r\n" -> "\n"

Checkout: "\n" -> "\r\n"

Don't know if that's helpful.

There is no '\r\n', but the changed line do have a lot of spaces in the middile of

changed line(for the align reason).

this snippet is the hd of changed lines:
