* logflags,proc: flag to log stacktrace execution Add a log flag to write logs about what the stacktracer does. * proc: read context from sigtrampgo, fixes TestCgoStacktrace2 on 1.21 Changes stacktrace code to read the signal context from the arguments of sigtrampgo. Also changes the automatic fatalthrow breakpoint for go 1.21. In combination these two changes fix TestCgoStacktrace2 on Go 1.21 on various platforms.

Help about logging flags.
|
|
|
|
### Synopsis
|
|
|
|
Logging can be enabled by specifying the --log flag and using the
|
|
--log-output flag to select which components should produce logs.
|
|
|
|
The argument of --log-output must be a comma separated list of component
|
|
names selected from this list:
|
|
|
|
|
|
debugger Log debugger commands
|
|
gdbwire Log connection to gdbserial backend
|
|
lldbout Copy output from debugserver/lldb to standard output
|
|
debuglineerr Log recoverable errors reading .debug_line
|
|
rpc Log all RPC messages
|
|
dap Log all DAP messages
|
|
fncall Log function call protocol
|
|
minidump Log minidump loading
|
|
stack Log stacktracer
|
|
|
|
Additionally --log-dest can be used to specify where the logs should be
|
|
written.
|
|
If the argument is a number it will be interpreted as a file descriptor,
|
|
otherwise as a file path.
|
|
This option will also redirect the "server listening at" message in headless
|
|
and dap modes.
|
|
|
|
|
|
|
|
### Options
|
|
|
|
```

|
```

```
|
|
--accept-multiclient Allows a headless server to accept multiple client connections via JSON-RPC or DAP.
|
|
--allow-non-terminal-interactive Allows interactive sessions of Delve that don't have a terminal as stdin, stdout and stderr
|
|
--api-version int Selects JSON-RPC API version when headless. New clients should use v2. Can be reset via RPCServer.SetApiVersion. See Documentation/api/json-rpc/README.md. (default 1)
|

--backend string Backend selection (see 'dlv help backend'). (default "default")
|
|
--build-flags string Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v"
|

--check-go-version Exits if the version of Go in use is not compatible (too old or too new) with the version of Delve. (default true)
|
|
--disable-aslr Disables address space randomization
|
|
--headless Run debug server only, in headless mode. Server will accept both JSON-RPC or DAP client connections.
|
|
--init string Init file, executed by the terminal client.

|
--log-output string Comma separated list of components that should produce debug output (see 'dlv help log')
|
|
--only-same-user Only connections from the same user that started this instance of Delve are allowed to connect. (default true)
