Gopass bridge on macOS Firefox fails because of incorrect message size

[hcl31415]

On macOS with newly installed Firefox gopass-bridge fails because of wrong message size:

Native application tried to send message of 1162690894 bytes, which exceeds the limit of 1048576 bytes.

macOS: 10.14.6

Firefox: 76.0.1 (64-bit)

GPG: gpg (GnuPG/MacGPG2) 2.2.17 libgcrypt 1.8.5

Gopass: gopass 1.9.2

Can you please provide the content of

❯ cat ~/Library/Application\ Support/Mozilla/NativeMessagingHosts/com.justwatch.gopass.json
{
    "name": "com.justwatch.gopass",
    "description": "Gopass wrapper to search and return passwords",
    "path": "/Users/martin/.config/gopass/gopass_wrapper.sh",
    "type": "stdio",
    "allowed_extensions": [
        "{eec37db0-22ad-4bf1-9068-5ae08df8c7e9}"
    ]
}

and the gopass_wrapper.sh

❯ cat /Users/martin/.config/gopass/gopass_wrapper.sh
#!/bin/sh

if [ -f ~/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
    source ~/.gpg-agent-info
    export GPG_AGENT_INFO
else
    eval $(gpg-agent --daemon)
fi

export PATH="$PATH:/usr/local/bin" # required on MacOS/brew
export GPG_TTY="$(tty)"

/usr/local/bin/gopass jsonapi listen

exit $?

Seems pretty much the same as yours:

gpg-agent is running, sourcing ~/.gpg-agent-info returns /Users/hcl/.gnupg/S.gpg-agent:1226:1 (agent is also active behind this socket).

FYI: I could also replicate this behaviour on another machine with Catalina installed. It works fine though on Arch Linux with the same version of Firefox.

Manifest:

hcl@artesonraju: ~ > cat Library/Application\ Support/Mozilla/NativeMessagingHosts/com.justwatch.gopass.json
{
    "name": "com.justwatch.gopass",
    "description": "Gopass wrapper to search and return passwords",
    "path": "/Users/hcl/Library/Application Support/gopass/gopass_wrapper.sh",
    "type": "stdio",
    "allowed_extensions": [
        "{eec37db0-22ad-4bf1-9068-5ae08df8c7e9}"
    ]
}

Wrapper:

hcl@artesonraju: ~ > cat .config/gopass/gopass_wrapper.sh
#!/bin/sh

if [ -f ~/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
    source ~/.gpg-agent-info
    export GPG_AGENT_INFO
else
    eval $(gpg-agent --daemon)
fi

export PATH="$PATH:/usr/local/bin" # required on MacOS/brew
export GPG_TTY="$(tty)"

/usr/local/bin/gopass jsonapi listen

exit $?

Actually, I could narrow down the problem: It doesn't seem to be directly related to gopass or gopass-bridge.

It fails only if one uses gpg included in GPGTools for Mac, the error disappears, when reverting to brew installed gpg (GPGTools still behave correctly with only the brew installed gpg binaries).

So I think that issue can be closed.

OK, thx for investigating.

I am seeing this issue even with the brew gpg package installed and the mactools GPGSuite not installed. Any other ideas?
