MacVim @8.0.snapshot124 spams console with input method errors

[PaulForgey (Paul Forgey)]

(macOS 10.12.3)

launching mvim from a Terminal window results in the somewhat frequent occurrence of the NSLog() output to the terminal from which mvim was launched:

2017-03-22 11:19:24.847 MacVim[601:9802] IMKInputSession presentFunctionRowItemTextInputViewWithEndpoint:completionHandler: : *NO* NSRemoteViewController to client, NSError=Error Domain=NSCocoaErrorDomain Code=4099 "The connection from pid 0 was invalidated from this process." UserInfo={NSDebugDescription=The connection from pid 0 was invalidated from this process.}, com.apple.inputmethod.EmojiFunctionRowItem

This is disruptively annoying as mvim is not usually used in isolation, but along side edit/run/debug activity in Terminal.

Would seem to be a Macvim thing rather than a Macports thing to fix....

It appears that this was dismissed by upstream at least twice. The upstream issues have been closed although there was no solution.

the little script they suggest in one of those reports that launches mvim while redirecting the errors to null would certainly seem the easiest solution, unless you are in the mood to fix their source code for them.

[raimue (Rainer Müller)]

In any case this should be handled upstream. As the other reports show, this is not specific to MacVim provided by MacPorts.

Such a wrapper script is not a good solution, as it hides any startup errors and might leave users clueless about problems. Nevertheless, if upstream decides this is the correct way to tackle this problem, then this should be done in the mvim wrapper script as shipped with MacVim.

[kencu (Ken)]

Indeed. That's why I was surprised when you assigned this to yourself rather than closing it.

[raimue (Rainer Müller)]

The ticket was assigned to me because I am the maintainer of the corresponding port. I acknowledge this is a issue that should be addressed. I am leaving the ticket open as long as the issue exists, so others can find it if they have the same problem.

[raimue (Rainer Müller)]

Upstream should decide how to handle this, but so far the issue is being ignored.
