Commit 30cdedae6910f5e9af6739845bacfd5b8778e745 introduced a dependency
from service/dap to pkg/terminal to call a stack printing function,
it's weird to have code that implements the DAP protocol depend on the
code for the JSON-RPC client.
Move PrintStack to a different package that can be called by both.
On hovers, including the full value for complex types is unnecessary, since the user will likely need to expand the children to inspect the values. Additionally, this can really slow down getting the hover values. This change will allow truncating the value in hover if the variable has a variables reference.
Updates golang/vscode-go#1435
Apply a presentation hint to the internal runtime stack frames, so that these can be deemphasized in the UI. This should allow
users to more easily inspect their own code, and will keep the option to view those frames if they choose to.
If the client supports paging, we allow them to fetch array and slice items in chunks that we assume will be of a reasonable size. For example, VS Code requests indexed variables in chunks of 100.
Fixesgolang/vscode-go#1518
- add 'clipboard' capability
- apply a larger string limit for 'hover' and 'clipboard' context
- truncate the string representation of compound (or pointer of compound)
type variable
If the base address isn't set then indexing and slicing will not work.
Large floating point registers already had the base set but small
general purpose registers did not.

Adds DWARF register number and support for AVX-512 registers.
Changes proc/gdbserial so that the 'g' and 'G' commands are never used
with debugserver since they seem to corrupt the thread state when used
on AVX-512 capable hardware.
Also changes TestClientServer_FpRegisters to be simpler and more
resilient to changes to the Go runtime.

* dap: use larger variable load limits in 'repl', 'variables' context
When evaluate requests are triggered in the context of 'repl'
(DEBUG CONSOLE in VSCode) or 'variables' (copy values from VARIABLES
section in VSCode), they are the result of human action and have
more rooms to display. So it is not too bad to apply longer limits.
Variable auto-loading for strings or arrays is nice but currently
it's unclear to me how this should be integrated in the DEBUG
CONSOLE or with the Copy Value feature. Until we have better ideas
and tools, let's go with these larger limits.
Unfortunately, the "Copy Value" from WATCH section triggers evaluate
requests with "watch" context and we don't want to load large data
automatically for "watch". So, users who want to query a large value
should first copy the expression to DEBUG CONSOLE and evaluate it.
Not ideal but not the end of the world either.
Updates golang/vscode-go#1318
* dap: apply large limit only to the string type result
* dap: move string reload logic to convertVariable* where other reload logic is
Currently we are thinking string reload for evaluation as a temporary
workaround until we figure out an intutitive way to present long strings.
So, I hope moving this logic near other reload logic may be better.
And, use the address based expression when reloading - when handling the
function return values, we may not have an expression to use.
* dap: make deep source check happy
* dap: move string reevaluation logic back to onEvaluateRequest
Reloading string variables is tricky if they are in registers.
We don't attempt to reload them but for clarity, move this up
to the onEvaluateRequest handler.
For function call, use a generous limit for string load
since the results are volatile.
* dap: check variable isn't affected by evaluate in other context
The Types field is only set in childrenToDAPVariables if the client
capability is supported. There is no need to check again after the
children have been calculated.
* dap: handle SetVariable requests
The handler invokes debugger.SetVariableInScope, except for
string type variables. For which, we rely on the `call` command.
Moved the call expression handling logic to the new `doCall`
function, so it can be reused by the SetVariable requenst
handler.
With this PR, every successful SetVariable request triggers
a StoppedEvent - that's a hack to reset the variablesHandle
map internally and notify the client of this change. It will
be nice if we can just update cached data corresponding to
the updated variable. But I cannot find an easy and safe way
to achieve this yet.
Also fixed a small bug in the call expression evaluation -
Previously, dlv dap returned an error "Unable to evaluate
expression: call stopped" if the call expression is for
variable assignment. (e.g. "call animal = "rabbit").
* dap: address comments from aarzilli
resetHandlesForStop & sendStoppedEvent unconditionally after
call command is left as a TODO - This is an existing code path
(just refactored) and an preexisting bug. Fixing it here
requires updates in TestEvaluateCallRequest and I prefer
addressing it in a separate cl.
Disabled call injection testing on arm64. Separated TestSetVariable
into two, one that doesn't involve call injection and another that
may involve call injection.
Fixed variableByName by removing unnecessary recursion.
* dap: address polina's comments
- removed the hard reset for every variable set
- added tests for various variable types
- added tests that involves interrupted function calls. (breakpoint/panic)
And,
- changed to utilize EvalVariableInScope to access the variable instead
of searching the children by name.
- changed to utilize evaluate requests when verifying whether the variable
is changed as expected in testing. Since now we avoid resetting the variable
handles after variable reset, either we need to trigger scope changes
explicitly, or stop depending on the variables request.
* dap: address comments
- Discuss the problem around the current doCall implementation
and the implication.
- Refine the description on how VS Code handles after setVariable
and evaluate request (there could be followup scopes/evaluate requests).
- Use the explicit line numbers for breakpoints in the SetVariable tests.
- Do not use errors.Is - we could've used golang.org/x/xerrors polyfill
but that's an additional dependency, and we will remove this check once
tests that depend on old behavior are fixed.
* dap: remove errTerminated and adjust the test
* dap: evaluate in the outer frame, instead of advancing to the next bp
On linux, delve RPC server allows only connections from the same user
if --only-same-user is set (true, by default). Do the same for DAP
server.
Moved the sameuser check logic to service/internal/sameuser.
Considered importing service/rpccommon from the dap server,
but when we eventually migrate to multiplex rpc and dap from one
port, I am afraid that can cause cyclic imports.

A RequestManualStop received while the target program is stopped can
induce a crash when the target is restarted.
This is caused by the phantom breakpoint detection that was introduced
in PR #2179 / commit e69d536.
Instead of always interpreting an unexplained SIGTRAP as a phantom
breakpoint memorize all possible unreported breakpoint hits and only
act on it when the thread hasn't moved from one.
Also clarifies the behavior of the halt command when it is received
while the target is stopped or in the process of stopping.
Handle the signaled status for the thread leader like we handle the
exited status, by returning ErrProcessExited and recording the killer
signal in it.
Prior to this commit we would find out about the death of the thread
later in the loop, the condition would still be reported as
ErrProcessExited, but without recording the signal number anywhere.
Also fixes a bug in TestAttachStopOnEntry where the test would
inadvertently cause a SIGPIPE to be sent to the target process, making
it terminate early.

Updates #279
daptest has type assertion functions that panic
if the read response/event message is not
the expected type. This is not only against the
recommended style guideline (Don't Panic, Useful
Test Failures, ...), but also it prevents from
quickly diagnosing test failures occurred in remote
CIs.
This PR changes the type assertion to the two
return value type assertion, and t.Fatal with details
if the type is not expected.
service/dap/daptest/main.go is a program that auto
generates those assertion functions in resp.go.
Run `go generate` from the service/dap directory
to update resp.go.
The client can specify certain configurations in the initialize request.
For example, pathFormat determines the pathFormat. We do not currently
support configuring pathFormat, linesStartAt1, or columnsStartAt1, so
we report an error if the client attempts to set these to an
unsupported value.
Changes the expression evaluation code so that register names, when not
shadowed by local or global variables, will evaluate to the current
value of the corresponding CPU register.
This allows a greater flexibility with displaying CPU registers than is
possible with using the ListRegisters API call. Also it allows
debuggers users to view register values even if the frontend they are
using does not implement a register view.

* service/rpcommon: resolve race between Detach and shutdown
Detach will close DisconnectChan causing the server to initiate
shutdown, there is a race between Detach writing its response to the

If Detach loses the race the response to the Detach request is never
sent to the client and the client will report an EOF error instead.
This change delays the start of the shutdown process until after Detach
has written its response.

Uniform use of ErrProcessExited to the non-pointer version.
Fixes intermittent failure of TestStepOutPreservesGoroutine.
When restarting we must take care of setting breakpoint IDs correctly
so that enabled breakpoints do not end up having the same ID as a
disabled breakpoint, also we must make sure that breakpoints created
after restart will not get an ID already used by a disabled breakpoint.
* dap: change how noDebug launch request is served
PR #2400 added support for noDebug launch requests - that was done
by directly starting the target program using os/exec.Cmd and blocking
the launch request indefinitely until the program terminates or
is stopped with a disconnect request (when dlv dap can support it).
Even though the approach seemed to work for user, that adds an extra
control flow and complexity to the codebase.
This change takes a different approach to implement the noDebug
launch feature. Instead of using os/exec.Cmd, this uses the existing
debug launch path, but avoids setting breakpoints. Finally, the program
will start upon receiving onConfigurationDoneRequest and blocks there
until the program terminates. This simplifies the code.
The DAP spec does not explicitly specify what to do about other
requests. It seems like VSCode can issue evaluate requests or other
requests after the configuration done request. Currently they are
blocked because the program is in running state. We can consider checking
s.noDebug and responding with an error in the future if we want/need to.
See the log below for a typical DAP request/response sequence:

* service/dap: address polina's comments for noDebug logic
Reworked so the noDebug launch request again blocks launch request
handler after responding with the launch response. By skipping
the initialized event, it should prevent well-behaving clients from
sending any further requests. Currently, doesn't matter because
the handler goroutine will be blocked until the program termination
anyway.
Placed mutex back, since I noticed that's the only way to prevent
racing between Stop and the handler goroutine. The synchronization
lotic (in particular, during teardown) should be revisited after
asynchronous request support work is done.

If the launch requests has noDebug attribute set, run the built
binary directly. The launch request handler will block until
the binary terminates, so the editor won't send additional requests
like breakpoint setting etc. Still disconnect or restart requests
can flow in though and they should trigger killing of the target
process if it's still running.
In order to run the binary using os/exec on windows, the target
binary has to have .exe as its extension. So, add .exe to the default
output name if it is on windows. I am not sure though yet we want
to modify the user-specified output or not yet. Considering how
go commands behave (not automatically append .exe for 'go build -o')
I think respecting what user specified is right, but the failure
(file not exist) may be mysterious.

Adds the `dump` command that creates a core file from the target process.
Backends will need to implement a new, optional, method `MemoryMap` that

Additionally the method `DumpProcessNotes` can be implemented to write out
to the core file notes describing the target process and its threads. If
DumpProcessNotes is not implemented `proc.Dump` will write a description of
the process and its threads in a OS/arch-independent format (that only Delve
understands).
Currently only linux/amd64 implements `DumpProcessNotes`.
Core files are only written in ELF, there is no minidump or macho-o writers.

Both structMember and findMethod implemented a depth-first search in
embedded fields but the Go specification requires a breadth-first
search. They also allowed promotion of fields in the concrete type of
embedded interfaces even though this is not allowed by Go.
Furthermore they both lacked protection from infinite recursion
when a type embeds itself and the user requests a non-existent field.

* proc: fix cgo stacktraces in Go 1.16 with simplified C -> Go call path
* dwarf/line: make dwarf/line correct when '\\' are used
Our code depends heavily on paths being '/' separated because go always
produced '/' separated file paths. The call to filepath.Join will
normalize the paths, on windows, to always be '\\' separated, which
violated our assumptions.
This didn't use to be a problem because the codepath that calls
filepath.Join was never exercised by executable files produced by Go,
but Go 1.16 started producing debug_line sections that use the
directory table with https://go-review.googlesource.com/c/go/+/263017/.
Fix this to always use path.Join after making sure, on windows, to
always normalize paths to use '/' as a separator. Replace the use of
filepath.IsAbs with an operating system independent version.
* goversion: bump supported Go version
Fix bug in DAP test: TestEvaluateCallRequest.
In Go 1.15 the call injection will be executed on a different goroutine

goroutine ID from the stopped response instead of assuming 1 is the
currently selected goroutine.
