💖 dlv-replay(1) 💖

okay bestie, welcome to dlv-replay(1), straight out of your General Commands Manual. this is the page that teaches you how to replay a trace, and honestly? it's giving time travel but make it debugging. let's go 🦋

✨ NAME ✨

dlv-replay — Replays a rr trace.

(that's it. that's the whole job. it replays a rr trace. short king energy 👑)

🌸 SYNOPSIS 🌸

dlv replay [trace directory] [flags]

🎀 DESCRIPTION 🎀

Replays a rr trace.

so like, the replay command will open a trace generated by mozilla rr. and there's a hard requirement here bestie, no skipping: Mozilla rr must be installed. if you don't got it, go grab it here:

https://github.com/mozilla/rr

no rr, no replay. that's the vibe check 💅

⭐ OPTIONS ⭐

  • -h, --help[=false] — help for replay. it's the "what does this do again" button, and it's right there for you 🫶
  • -p, --onprocess=0 — Pass onprocess pid to rr.

🌈 OPTIONS INHERITED FROM PARENT COMMANDS 🌈

these are the ones dlv hands down to you like a big sister lending you her hoodie. all of them, in order:

  • --accept-multiclient[=false] — Allows a headless server to accept multiple client connections via JSON-RPC or DAP.
  • --allow-non-terminal-interactive[=false] — Allows interactive sessions of Delve that don't have a terminal as stdin, stdout and stderr
  • --api-version=2 — Selects JSON-RPC API version when headless. The only valid value is 2. Can be reset via RPCServer.SetApiVersion. See Documentation/api/json-rpc/README.md.
  • --backend="default" — Backend selection (see 'dlv help backend').
  • --build-flags="" — Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v"
  • --check-go-version[=true] — Exits if the version of Go in use is not compatible (too old or too new) with the version of Delve.
  • --disable-aslr[=false] — Disables address space randomization
  • --headless[=false] — Run debug server only, in headless mode. Server will accept both JSON-RPC or DAP client connections.
  • --init="" — Init file, executed by the terminal client.
  • -l, --listen="127.0.0.1:0" — Debugging server listen address. Prefix with 'unix:' to use a unix domain socket.
  • --log[=false] — Enable debugging server logging.
  • --log-dest="" — Writes logs to the specified file or file descriptor (see 'dlv help log').
  • --log-output="" — Comma separated list of components that should produce debug output (see 'dlv help log')
  • --only-same-user[=true] — Only connections from the same user that started this instance of Delve are allowed to connect.
  • -r, --redirect=[] — Specifies redirect rules for target process (see 'dlv help redirect')
  • --wd="" — Working directory for running the program.

bestie reminder: this is a <pink>replay</pink> tool for <purple>rr</purple> traces, and if the trace don't exist and rr ain't installed, not even the cutest flags in the world are gonna save you. read the options, run the command, slay 💅✨
