* cmds/commands: Update 'client-addr' to support Unix domain sockets
This change updates the '--client-addr' flag to accept Unix domain sockets (UDS). Currently, the --listen flag supports UDS, but --client-addr does not. This modification ensures consistency across the APIs and improves support for vscode-go, which uses reverse mode (via client-addr) to connect to DAP.
Fixes#3814
* Undo formatter changes in dlv_test.go
* Update commands.go
The step command is changed such that when the function being currently
called is a coroutine switch function it will move to the associated
coroutine.
Functions that switch coroutines are currently the next, stop and yield
closures produced by the iter.Pull function.
* proc: flag variables correctly when range-over-func stmts are used
Argument variables of a range-over-func body closure should be returned
flagged as normal local variables, not as function arguments.
Updates #3806
* proc: for optimized functions allow .closureptr to not exist
For optimized functions .closureptr is sometimes omitted from DWARF,
allow it to be 0 and try to recover the range-over-func stack by best
effort.
Fixes#3806
We have a check for Rosetta that should point users towards
misconfiguration, however occasionally we still get new issues about
debugserver crashing and some of those, as it turns out, are still
caused by Rosetta (see for example #3804).
Check the output of 'uname -m' and check that it isn't 'x86_64' if we
are an 'arm64' process: if that happens we are running unemulated but
debugserver will refuse to work.
The Go specification says that the result of division of untyped
constants should be an untyped integer constant if both constants are
untyped integers, the go/constant package however does something
different by always producing an untyped floating constant.
Fixes#3793
The oldest version of Go we compile with is 1.20 at this point, we can
thus make use of generic type parameters and the handlesMap support
type in service/dap is improved by them.
Go 1.23 and earlier does not take into account that Mach-O section
names are limited to 16 characters, which causes DWARF sections with
long names to be truncated and become unreadable.
Fixes#3797
* terminal/starbind: fix starlark conversion of named consts
If a value of a derived integer type matches a named constant,
Delve will wrap the string representation of the value with
the name of the constant, causing ParseInt/ParseUint to fail.
This change removes the wrapping before attempting to parse
the value before sending it to Starlark.
* terminal: add starlark tests for enums
TestRangeOverFuncNext and TestRangeOverFuncNextInlined are failing on
linux/386 with go1.23 due to an inconsistency on how append works on
32bit platforms.
Fixes a repeated stop on the first line of a range-over-func body when
stepping through a program. The entry point breakpoint is changed to a
special breakpoint that, when hit:
- clears the current temporary breakpoints
- sets breakpoints like 'next' would, and
- resumes execution.
Move all tests of the functionality of proc.next,
proc.(*TargetGroup).Next, proc.(*TargetGroup).Step,
proc.(*TargetGroup).StepOut to their own test file.
Add 1.23 to supported versions and to test matrix, remove 1.19 and 1.20
from supported versions (1.19 should have been removed long ago, but we
forgot to do it on release).
Set a breakpoint on the return address of the current function, if it's
a range-over-func body, and clear the stepping breakpoints for the
current function (except the entry one) when its hit.
Without this what can happen is the following:
1. the range-over-func body finishes and returns to the iterator
2. the iterator calls back into the range-over-func body
3. a stepping breakpoint that's inside the prologue gets hit
Updates #3733
* proc: use .closureptr for stepping through range-over-func statements
Uses special variables .closureptr and #yieldN to correctly identify
the parent frame of a range-over-func body closure call.
Updates #3733
* fix
We are already importing v3 indirectly for github.com/spf13/cobra/doc,
update our own dependency to v3 as well so that we can delete one
module from the vendor directory.
Fixes bug where the incorrect Build ID could be used to try and download the source for a binary. This is because the Build ID was stored on the BinInfo object for a target and not the image itself.
Supports viewing local variables and evaluating expressions correctly
when range-over-func is used.
The same limitations that the previous commit on this line had still
apply (no inlining, wrong way to identify the range parent in some
cases).
Updates #3733
Because of how range-over-func is implemented it is difficult to
determine the set of visible local variables during expression
compilation (i.e. it is difficulto to keep the HasLocal function
correct).
This commit moves that logic from expression compilation to expression
evaluation.
Updates #3733
When stack watchpoints go out of scope simultaneously they can hide (or
duplicate the effect) of other breakpoints (including other watchpoints
going out of scope) that are placed on the same physical memory
location.
This happens because we delete the watchpoint-out-of-scope breakpoint
while we are evaluating hit breakpoints, mangling the breaklets list.
This commit moves breakpoint deletion out of the
watchpoint-out-of-scope condition, delaying it until all hit
breakpoints have been evaluated.
Also fix bug where on amd64 if all four watchpoints are in use the last
one is not checked.

Initial support for stepping in functions that use the new
range-over-func statement in go1.23.
Does not support:
- inlining
- viewing variables of the enclosing function from a range-over-func
body closure
- the correct way to find the enclosing function from a range-over-func
body closure (but it should work most of the time).
Updates #3733
