If the argument of 'source' ends in '.star' it will be interpreted as a
starlark script.
If the argument of 'source' is '-' an interactive starlark repl will be
started.
For documentation on how the starlark execution environment works see
Documentation/cli/starlark.md.
The starlark API is autogenerated from the JSON-RPC API by
script/gen-starlark-bindings.go.
In general for each JSON-RPC API a single global starlark function is
created.
When one of those functions is called (through a starlark script) the
arguments are converted to go structs using reflection. See
unmarshalStarlarkValue in pkg/terminal/starbind/conv.go.
If there are no type conversion errors the JSON-RPC call is executed.
The return value of the JSON-RPC call is converted back into a starlark
value by interfaceToStarlarkValue (same file):
* primitive types (such as integers, floats or strings) are converted
by creating the corresponding starlark value.
* compound types (such as structs and slices) are converted by wrapping
their reflect.Value object into a type that implements the relevant
starlark interfaces.
* api.Variables are treated specially so that their Value field can be
of the proper type instead of always being a string.
Implements #1415, #1443
* proc: allow simultaneous call injection to multiple goroutines
Changes the call injection code so that we can have multiple call
injections going on at the same time as long as they happen on distinct
goroutines.
* proc: fix EvalExpressionWithCalls for constant expressions
The lack of address of constant expressions would confuse EvalExpressionWithCalls
Fixes#1577
Adds initial support for plugins, this is only the code needed to keep
track of loaded plugins on linux (both native and gdbserial backend).
It does not actually implement support for debugging plugins on linux.
Updates #865
The repository is being switched from the personal account
github.com/derekparker/delve to the organization account
github.com/go-delve/delve. This patch updates imports and docs, while
preserving things which should not be changed such as my name in the
CHANGELOG and in TODO comments.
Instead of unconditionally returning all present goroutines,
GoroutinesInfo now allows specifying a range (start and count). In
addition to the array of goroutines and the error, it now also returns
the next goroutine to be processed, to be used as 'start' argument on
the next call, or 0 if all present goroutines have already been
processed.
This way clients can avoid eating large amounts of RAM while debugging
core dumps and processes with a exceptionally high amount of goroutines.
Fixes#1403
Adds -defer flag to the stack command that decorates the stack traces
by associating each stack frame with its deferred calls.
Reworks proc.next to use this feature instead of using proc.DeferPC,
laying the groundwork to implement #1240.
Implements the function call injection protocol introduced in go 1.11
by https://go-review.googlesource.com/c/go/+/109699.
This is only the basic support, see TODO comments in pkg/proc/fncall.go
for a list of missing features.
Updates #119
This pull request makes several changes to delve to allow headless
instancess that are started with the --accept-multiclient flag to
keep running even if there is no connected client. Specifically:
1. Makes a headless instance started with --accept-multiclient quit
after one of the clients sends a Detach request (previously they
would never ever quit, which was a bug).
2. Changes proc/gdbserial and proc/native so that they mark the
Process as exited after they detach, even if they did not kill the
process during detach. This prevents bugs such as #1231 where we
attempt to manipulate a target process after we detached from it.
3. On non --accept-multiclient instances do not kill the target
process unless we started it or the client specifically requests
it (previously if the client did not Detach before closing the
connection we would kill the target process unconditionally)
4. Add a -c option to the quit command that detaches from the
headless server after restarting the target.
5. Change terminal so that, when attached to --accept-multiclient,
pressing ^C will prompt the user to either disconnect from the
server or pause the target process. Also extend the exit prompt to
ask if the user wants to keep the headless server running.
Implements #245, #952, #1159, #1231
Displays the return values of the current function when we step out of
it after executing a step, next or stepout command.
Implementation of this feature is tricky: when the function has
returned the return variables are not in scope anymore. Implementing
this feature requires evaluating variables that are out of scope, using
a stack frame that doesn't exist anymore.
We can't calculate the address of these variables when the
next/step/stepout command is initiated either, because between that
point and the time where the stepout breakpoint is actually hit the
goroutine stack could grow and be moved to a different memory address.
* command/terminal: allow restart to change process args
Add -args flag to "restart" command. For example, "restart -args a b c" will
pass args a b c to the new process.
Add "-c" flag to pass the checkpoint name. This is needed to disambiguate the
checkpoint name and arglist.
Reverted unnecessary changes.
* Applied reviewer comments.
Vendored argv.
Change the syntax of restart. When the target is is in recording mode, it always
interprets the args as a checkpoint. Otherwise, it interprets the args as
commandline args. The flag "-args" is still there, to handle the case in which
the user wants to pass an empty args on restart.
* Add restartargs.go.
Change "restart -args" to "restart -noargs" to clarify that this flag is used to
start a process with an empty arg.
* service/debugger: Restore breakpoints using file:line on restart
Restoring by address can cause the breakpoint to be inserted in the
middle of an instruction if the executable file has changed.
* terminal: Warn of stale executable when printing source
* proc: bugfix: StepInto can not function when temp bps exist
* terminal,service: auto-continue during next and step
Make dlv call continue automatically when a breakpoint is hit on a
different goroutine during a next or step operation.
Added API hooks to implement the other solution to this problem (cancel
the next/step operation if a different breakpoint is hit).
Fixes#387
* service/api: Removed unused fields of service/api.Function
* proc/eval: Set return variable name to input expression
* all: fine-grained control of loadValue for better variable printing
Makes proc.(*Variable).loadValue loading parameters configurable
through one extra argument of type LoadConfig.
This interface is also exposed through the API so clients can control
how much of a variable delve should read.
New API version with better backwards compatibility plus mechanism to
select the API version that a headless instance should use.
Adds service/test/cmd/typecheckrpc.go to type check the RPC interface.
Breakpoints, tracepoints, etc.. take a location spec as input. This
patch improves the expressiveness of that API. It allows:
* Breakpoint at line
* Breakpoint at function (handling package / receiver smoothing)
* Breakpoint at address
* Breakpoint at file:line
* Setting breakpoint based off regexp
Refactor to introduce client/server separation, including a typed
client API and a HTTP REST server implementation.
Refactor the terminal to be an API consumer.
