An internal breakpoint condition shouldn't ever error:
* use a ThreadContext to evaluate conditions if a goroutine isn't
available
* evaluate runtime.curg to a fake g variable containing only
`goid == 0` when there is no current goroutine
Fixes#2113
Recent changes to the way registers are handled broke reporting of AVX
registers (i.e. YMMx). This change restores the functionality by:
- concatenating the higher half of the YMMx registers to their
corresponding XMMx lower half (YMMx registers do not have an
independent DWARF register number)
- modifying the formatSSEReg function to handle them when they are
present.
Fixes#2033

* proc: start variable visibility one line after their decl line
In most cases variables shouldn't be visible on their declaration line
because they won't be initialized there.
Function arguments are treated as an exception.
This fix is only applied to programs compiled with Go 1.15 or later as
previous versions of Go did not report the correct declaration line for
variables captured by closures.
Fixes#1134
* proc: silence go vet error
* Makefile: enable PIE tests on windows/Go 1.15
* core: support core files for PIEs on windows
* goversion: add Go 1.15 to supported versions
* proc: fix function call injection for Go 1.15
Go 1.15 changed the call injection protocol so that the runtime will
execute the injected call on a different (new) goroutine.
This commit changes the function call support in delve to:
1. correctly track down the call injection state after the runtime
switches to a different goroutine.
2. correctly perform the escapeCheck when stack values can come from
multiple goroutine stacks.
* proc: miscellaneous fixed for call injection under macOS with go 1.15
- create copy of SP in debugCallAXCompleteCall case because the code
used to assume that regs doesn't change
- fix automatic address calculation for function arguments when an
argument has a spurious DW_OP_piece at entry
The file:line information for the entrypoint is more acccurate than the
file:line information at a return point, which could be affected by a
compiler bug.
Fixes#2086
Recent change #2061:
292f5c69f0c769fd32c2e8b1e7153b56e908efd7
proc: step into unexported runtime funcs when already inside runtime
means that TestIssue414 (which tries to step repeatedly until the
program exits) can now steps through way more runtime code than it ever
did before. This causes this test to occasionally fail. Stepping
blindly through runtime code has never been particularly safe as the
runtime can switch to a different goroutine causing Delve to misbehave.
This change restores the previous behavior of TestIssue414 where Step
behaved like Next inside runtime code.
These methods only work if registers have been loaded once after the
last resume, there's probably no code path that calls SetXX before
Thread.Registers but lets make sure it can't happen anyway.
Clarify that the currently supported version of the API is 2 and that
the preferred method for selecting it is sending a SetApiVersion
command after connection.
Fixes#2066
On platforms other than macOS this doesn't matter but on macOS a
segmentation fault will cause ContinueOnce to return an error, before
returning it we should still fix the current thread and selected
goroutine values.
Fixes#2078
* terminal/command: Add 'reload' command
These changes add the 'reload' command, which allows us to rebuild the project
and start the debugging session again. Currently, if the project's code is
updated while debugging it, Delve shows the new source code, but it's still
running the old one. With 'reload', the whole binary is rebuilt, and the
process starts again.
Fixes#1551

Change from debugger.ExecutingGeneratedTest to

We are generating a real binary instead of a test

Normally we don't step into unexported runtime functions because the
compiler is free to insert them into the code and they are not relevant
to the user, however if we are already stepping through a runtime
function we should let step into work normally and step into other
runtime functions.
When reading truncated core files GoroutinesInfo will sometimes produce
some proc.G structs with only the Unreadable field set. These proc.G
can not be used for anything, but the service layer will still try to
convert them.
Since they are not fully initialized parts of the conversion will fail,
api.ConvertGoroutine should not try to call methods of unreadable
goroutines.

This issue causes a failure of TestTracePid that was observed in CI:
https://travis-ci.com/github/go-delve/delve/jobs/343053383
I'm not sure what causes it in this particular instance but there are
several ways in which a thread stopped at a breakpoint might have a
BreakpointInfo == nil field (see variable withBreakpointInfo in
debugger.Debugger.Command).
