Change file paths of error traces / debug info

Help
1

Is it possible to change the file paths in the error traces so they don’t show absolute file paths on the system that built the binary? I am trying to include error traces in my release builds so when a user is screwed they can give me better debug info, and I dont think they need the path to the repo on my laptop :slight_smile:

jeff@jeff-debian:~/repos/gatorcat$ sudo ./zig-out/bin/gatorcat --log-level warn run --ifname docker0
warning: Scheduler: NORMAL
error: Ping failed. No frame returned before the recv timeout. Is anything connected to the specified interface (docker0)?
error: NonRecoverable
/home/jeff/repos/gatorcat/src/module/Port.zig:297:9: 0x1794467 in sendRecvDatagram (gatorcat)
        return error.RecvTimeout;
        ^
/home/jeff/repos/gatorcat/src/module/Port.zig:309:9: 0x1747160 in nop (gatorcat)
    _ = try sendRecvDatagram(
        ^
/home/jeff/repos/gatorcat/src/module/Port.zig:269:5: 0x1746f86 in ping (gatorcat)
    try self.nop(1, timeout_us);
    ^
/home/jeff/repos/gatorcat/src/cli/run.zig:96:17: 0x178c4e8 in run (gatorcat)
                return error.NonRecoverable;
                ^
/home/jeff/repos/gatorcat/src/cli/main.zig:77:28: 0x178b722 in main (gatorcat)
        .run => |run_args| try run.run(gpa.allocator(), run_args),

As a workaround you might be able to create a custom mountpoint at /zig and then use that.

So basically
sudo mkdir /zig
sudo mount --bind /home/user/myactualpath/zig /zig

Then maybe have a version directory that contains the zig versions and a projects directory?

/zig
  version
    0.14.0
      zig
  projects
    gatorcat

(But if you only need the error return traces to be different, it might not matter from which path Zig is invoked)

I think with that setup your message would change to this:

jeff@jeff-debian:/zig/projects/gatorcat$ sudo ./zig-out/bin/gatorcat --log-level warn run --ifname docker0
warning: Scheduler: NORMAL
error: Ping failed. No frame returned before the recv timeout. Is anything connected to the specified interface (docker0)?
error: NonRecoverable
/zig/projects/gatorcat/src/module/Port.zig:297:9: 0x1794467 in sendRecvDatagram (gatorcat)
        return error.RecvTimeout;
        ^
/zig/projects/gatorcat/src/module/Port.zig:309:9: 0x1747160 in nop (gatorcat)
    _ = try sendRecvDatagram(
        ^
/zig/projects/gatorcat/src/module/Port.zig:269:5: 0x1746f86 in ping (gatorcat)
    try self.nop(1, timeout_us);
    ^
/zig/projects/gatorcat/src/cli/run.zig:96:17: 0x178c4e8 in run (gatorcat)
                return error.NonRecoverable;
                ^
/zig/projects/gatorcat/src/cli/main.zig:77:28: 0x178b722 in main (gatorcat)
        .run => |run_args| try run.run(gpa.allocator(), run_args),

Maybe you also could shorten it to directly /gatorcat.
