Issue Details

[If filing a bug report, please include a list of steps that describe how to reproduce the bug you are experiencing. Also include test code if relevant.]

Problem:

Errors pop up on the first entry to insert mode when editing a file large enough to trigger ycm_disable_for_files_larger_than_kb in vim

Minimal recreation:

• Create a text file larger than the trigger value (default: 1000k). For instance: openssl rand 1024000 -base64 -out ycm-test.txt

• Open this file in vim (optionally with a minimal vimrc.txt with YCM installed and compiled, etc: vim -u vimrc.txt ycm-test.txt N.B. this vimrc doesn't contain the two ycm debugging options, but they are set in my testing and reflected in the stderr log output below)

  and observe the message as expected:

YouCompleteMe is disabled in this buffer; the file exceeded the max size (see YCM op tions).

• Enter insert mode ('i') and observe the error message:

Error detected while processing function 194_SetOmnicompleteFunc[1]..194_P yeval:

And a moderate collection of further error messages show up. The full :messages output is attached: messages.txt

A bit of poking about suggests that the server is returning a 413 during a request in NativeFiletypeCompletionUsable, which is called from SetOmnicompleteFunc. Other things check ycm_largefile and bail if it's true, but that code path doesn't.

Requested debugging data

• vim --version output
• :YcmDebugInfo:

Printing YouCompleteMe debug information...
-- Server has Clang support compiled in: False
-- Server running at: http://127.0.0.1:54392
-- Server process ID: 111195
-- Server logfiles:

--   /tmp/ycm_temp/server_54392_stderr.log
Press ENTER or type command to continue

• :YcmToggleLogs stderr output (yes, it seems very minimal):
