"code object is not signed at all In subcomponent" error after High Sierra update.

[yoannmoinet]

Hi there,
I have updated my system to High Sierra a few days ago, and now I can't sign my apps anymore.

I've tested everything I could think off:

• updated certs
• updated provisioning
• updated dependencies
• delete everything and pull from scratch
• I will try to get a Sierra MBP to test the signing, to be sure it's really coming from HighSierra.

Always get the same error on the three Electron helpers.

• MyApp.app/Contents/Frameworks/MyApp Helper EH.app/Contents/MacOS/MyApp Helper EH
• MyApp.app/Contents/Frameworks/MyApp Helper NP.app/Contents/MacOS/MyApp Helper NP
• MyApp.app/Contents/Frameworks/MyApp Helper.app/Contents/MacOS/MyApp Helper

I don't know what to do anymore.

Here's the full error:

../release/MyApp-mas-x64/MyApp.app/Contents/Frameworks/MyApp Helper.app/: code object is not signed at all
In subcomponent: /Users/yoann/dev/myapp/release/MyApp-mas-x64/MyApp.app/Contents/Frameworks/MyApp Helper.app/Contents/MacOS/MyApp Helper

I've used a simple codesign script to pinpoint the problem :

#!/bin/bash

# Name of your app.
APP="MyApp"
# The path of your app to sign.
APP_PATH="../release/MyApp-mas-x64/MyApp.app"
# The path to the location you want to put the signed package.
RESULT_PATH="../release/$APP.pkg"
# The name of certificates you requested.

codesign -s "$APP_KEY" -f --entitlements "../build/child.plist" "$APP_PATH/Contents/MacOS/$APP"
codesign -s "$APP_KEY" -f --entitlements "../build/parent.plist" "$APP_PATH"

But the output is as follow:

Please note that my app has a ê in its name, if that could be relevent.
But I never had any issue with this before High Sierra update.

Thank you for your help.

Hi @yoannmoinet I'm updating my laptop to High Sierra tonight so'll be able to try testing out the issue. Would you provide a little more details about which Electron version you are using?

And it's a little weird that even a binary executable cannot be successfully signed. Did you manage to manually have this file individually signed?

../release/MyApp-mas-x64/MyApp.app/Contents/Frameworks/MyApp Helper.app/Contents/MacOS/MyApp Helper: code object is not signed at all

Also, I'm wondering if it's an older incompatible version of codesign that's used? Are your Xcode command line tools updated to the latest?

[yoannmoinet]

Hi @sethlu thank you for your fast answer.

I've tested both with electron 1.7.* and 1.8.1.

Tried to sign single executable as well, exact same result.

Right after the High Sierra update, I've launched XCode and it asked to install command line tools, which I did. So I guess I have the latest version there as well. I also had to reconnect my Apple Account in XCode, if it has any relevance at all.

[sethlu]

@yoannmoinet Mhm. I was just looking at electron-userland/electron-builder#2125 and that seems slightly related. Have you tried to package an app without non-ASCII characters and codesign that plain version?

---

Related? https://eclecticlight.co/2017/07/05/high-sierra-and-filenames-apple-is-relenting/

[yoannmoinet]

I'll try that later today as well, right after the Sierra test.
Will report back.

That would be weird that the non-ASCII characters is now an issue, since my app is signed and on the AppStore for several months now. I'll test it nonetheless.

[sethlu]

@yoannmoinet Great! I'll try to run a basic electron-quick-start packaging & signing and see it that works after the macOS version bump.

[yoannmoinet]

Removed the ê from the previous packaged application, and it signed correctly.

I think your link about the new file system is what's happening... god dammit Apple, what did you do?

I'll check a bit further this direction then.
This is so much trouble, I can't even understand how they overlooked this.

[yoannmoinet]

Got it to work.

It was indeed ê.
I copied another ê displayed in the Finder, and used it in my app.

Apparently, ê isn't supported by codesign, but ê is.
Should have figured this out 🙃

It is now working.

[sethlu]

@yoannmoinet I was able to reproduce the error with a ć as well. (I will post a link to a simplified version very soon.) Probably with the current set up--High Sierra--it's better to sign with ASCII compatible path names, though I think a build environment in Sierra should support distribution of signed apps in High Sierra?

[sethlu]

@yoannmoinet I've posted the reproduction here: reproduce-155. I think the issue boils down to the unicode string passed into codesign: The failing case with ê is <c3 aa>, whereas the working one is <65 cc 82> (more like combining a few emojis to a symbol.) So far I believe the latter is better supported in APFS. So by copying the name directly from Finder and pasting it as the app name the issue is resolved.

I think we can introduce a patch to address the unicode encoding issue?

[yoannmoinet]

@sethlu awesome stuff.

Copying from the Finder is indeed what I did to fix my issue.
But how do you see a patch for this?
I'm not that fluent in encoding matters unfortunately 😞 , at least for now.

Thank you very much for your support though, without your link to the eclecticlight post, I wouldn't have found the solution.

Should we re-open the issue?

[sethlu]

@yoannmoinet No worries! 👍 And I'm not very sure... But I'll find some time to try to devise a workaround for unicode normalization. Let's keep the issue open for some time until a fix is available.

You're a lifesafer! Copying the characters from finder solved the same issue for me.
