Agent crashes when attempting to login

[the-sun-will-rise-tomorrow]

rbw login fails with rbw login: failed to parse message from agent: EOF while parsing a value at line 1 column 0.

With RUST_BACKTRACE=1 rbw login, in .local/share/rbw/agent.err:

Same issue here on macOS.

Experiencing this as well on NixOS, regardless of whether I manage rbw's config via nix or not.

[Samasaur1]

I get this same issue on macOS with rbw installed via Nix, though setting RUST_BACKTRACE=1 doesn't give me any more information

[doy]

can you give this a try with version 1.10.0? i updated the dependency in use here, which may help.

[Samasaur1]

@doy I still see the same error

[Samasaur1]

and the only entry in agent.err is

WARN  rbw_agent] failed to disable PTRACE_ATTACH, agent memory may be dumpable by other processes: unimplemented on this platform

[doy]

did this just start happening recently? or has it always crashed?

[Samasaur1]

For me at least, this has always happened

[doy]

can you give me the output of ulimit -l and du -sh ~/.cache/rbw (or du -sh ~/Library/Caches/rbw if you're on macos)?

[Samasaur1]

[sam](~)$ ulimit -l
unlimited
[sam](~)$ du -sh ~/Library/Caches/rbw
  0B    /Users/sam/Library/Caches/rbw

[Samasaur1]

@doy I noticed that there were some new commits after v1.10.0, so I tried building that version, but still no luck (with the same error)

[doy]

i'm not sure what is actually going on here, but i've made this functionality optional in version 1.12 - let me know if this fixes the issue

[Samasaur1]

Still no luck on v1.12.0:

[sam](/tmp)$ clear
[sam](/tmp)$ rm ~/Library/Application\ Support/rbw/agent.*
[sam](/tmp)$ rbw --version
rbw 1.12.0
[sam](/tmp)$ rbw login
rbw login: failed to parse message from agent: EOF while parsing a value at line 1 column 0
[sam](/tmp)$ c ~/Library/Application\ Support/rbw/agent.*

For the record, v1.11.1 works fine on Linux
