Maximum number of diagnostics exceeded.

[jvillasante]

Description :octocat:

Using ycm I get 'Maximum number of diagnostics exceeded' on a file that otherwise compiles without warnings or errors.

Here's my ycmd debug info:

Ycmd debug information for buffer main.cpp in c++-mode:

Ycmd Mode is enabled

--------------------

Ycmd version:   1.3snapshot (package: 20180520.353)
Emacs version:  26.1
System:         x86_64-apple-darwin17.6.0
Window system:  mac

Here's my ycm_extra_conf.py

flags = [
  '-std=c++17',
  '-x', 'c++',
  '-stdlib=libc++',
  '-Wall',
  '-Wextra',
  '-Werror',
  '-pedantic',
  '-DDEBUG',
  '-Wno-gnu-case-range',
  '-isystem', '/usr/local/opt/llvm/include',
  '-isystem', '/usr/local/opt/llvm/include/c++/v1',
  '-I', '.',
]

def FlagsForFile( filename ):
  return {
    'flags': flags,
    'do_cache': True
  }

Also, on ycm debug info it can be seen that somehow I get more flags than the ones I defined on my extra config file. Is there a way to solve this?

It seems that ycmd is trying to parse system files as can be seen in this extract of the ycmd logs

(((kind . "ERROR")
  (text . "use of undeclared identifier 'wcschr'")
  (ranges)
  (location
   (filepath . "/usr/local/opt/llvm/include/c++/v1/wchar.h")
   (column_num . 77)
   (line_num . 137))
  (location_extent
   (start
    (filepath . "/usr/local/opt/llvm/include/c++/v1/wchar.h")
    (column_num . 77)
    (line_num . 137))
   (end
    (filepath . "/usr/local/opt/llvm/include/c++/v1/wchar.h")
    (column_num . 83)
    (line_num . 137)))
  (fixit_available . :json-false))

Is there a way to overcome this?

Changing .ycm_extra_config.py to this .ycm_extra_config file solves the issue. This one can be closed.

[Compro-Prasad]

@jvillasante Is this something that can be solved on spacemacs level? If not then this sure can be closed.

[jvillasante]

No, there's nothing that can be done on spacemacs level. I'm closing this.

if you use python 3 , please replace ur to r, and add decode() to output.

With the current ycm version, this new config file yields the parse error below. Looks like something has to be changed with the line:

regex = re.compile(ur'(?:\#include \<...\> search starts here\:)(?P<list>.*?)(?:End of search list)', re.DOTALL);

ycmd.responses.ServerError: SyntaxError: invalid syntax (.ycm_extra_conf.py, line 7)

EDIT: I notice the amend needed for Python 3. Could I know what it means to add decode() to output? Thanks.

Resolved. output -> output.decode() in the for p ... line. Thanks.
