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.
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
It seems newer MacOS kernels are sending mach exceptions for watchpoints
which contain the hardware register number as opposed to the address
which triggered the exception. Also, ARM64 seems to have switched to
sending _EXC_I386_SGL as medata[0] for this exception type.
Adds a recover to the functions reading debug info from the go runtime
data structures for stripped executables.
This function is best-effort and can sometimes fail in weird ways,
instead of crashing recover any panic and turn them into errors.
Fixes#3650
This allows us to update this dependency on our schedule which is important because the module relies on manually updating the known list of Go versions to function correctly. Forking allows us to keep this up to date ourselves and possibly create a new system to prevent having to perform this manual step in the future.
This patch switches from using a forked version of one of the libraries
of goretk/gore to using the module directly. This is possible now that
certain functionality has been exposed / fixed within that module making
it usable for Delve.
Instead of having a different version for each architecture have a
single version that uses an architecture specific list of registers.
Also generalize it so that, if we want, we can extend the workaround to
other runtime functions we might want to call (for example the channel
send/receive functions).
This patch adds support for listing and setting breakpoints on inlined functions within stripped binaries. It uses a forked version of `debug/gosym` copied from golang.org/x/vuln/internal/vulncheck/internal/gosym which adds support for parsing the inline tree of the pclntab section. Parsing this section requires knowing the offset of the "go:func.*" symbol, which is not present in stripped binaries via the ``.symtab` section so instead, we search the `.noptrdata` section which contains `runtime.moduledatap` which contains the value of that missing symbol, which we then can use to find the inline tree for a given function.
Given all this we parse the inline tree for each function we find, and then add that information the the appropriate `Function` contained in `bi.Functions`, using a relatively empty `Function` struct as what would be the abstract origin.
Go1.22 switched to emitting PIE by default and also changed some
details of the PIE implementation. This breaks delve entirely on macOS.
Fix how relocations are handled on macOS.
Only print the warning that gopclntab can not be read for the first
image (i.e. the executable file), also change the returned when neither
DWARF nor gopclntab are found to preserve the DWARF error.
We used to parse the .gopclntab section but removed support in favor of
simply using DWARF debug information, due to lack of C symbols among
other reasons. This makes it impossible to debug stripped binaries,
which some distrubutions ship by default.
Add back in basic support for .gopclntab which survives if the binary
is stripped, allowing for rudimentary debugging such as basic
program navigation, tracing, etc...
Go 1.21 renamed runtime._type to internal/abi.Type and changed the name
of its fields. Update Delve so that it uses the new names for loading
interfaces and generic type parameters.
A series of interconnected changes to both the terminal command
'config', DAP command 'dlv config', quality of life improvements to how
substitute-path works, and better documentation.
- Let 'config substitute-path' show the current substitute path rules
- Add a -clear command to 'config substitute-path'
- Support 'config-debug-info-directories'
- rewrite SubstitutePath to be platform independent (see below)
- document path substitution more
Regarding the rewrite of SubstitutePath: the previous version used
runtime.GOOS and filepath.IsAbs to determine which filepath separator to use
and if matching should be case insensitive. This is wrong in all situations
where the client and server run on different OSes, when examining core files
and when cross-compilation is involved.
The new version of SubstitutePath checks the rules and the input path to
determine if Windows is involved in the process, if it looks like it is it
switches to case-insensitive matching. It uses a lax version of
filepath.IsAbs to determine if a path is absolute and tries to avoid having
to select a path separator as much as possible
Fixes#2891, #2890, #2889, #3179, #3332, #3343
The compiler produces ABI compatibility wrappers for some functions.
We have changed the support for breakpoints to allow a single logical
breakpoint to correspond to multiple physical breakpoints, take
advantage of that to set breakpoints on both the ABI wrapper and the
real function.
Fixes#3296
* terminal/logflags: Added `SetLoggerFactory(LoggerFactory)`
This change will enable people who want to embed Delve into their applications to adjust the logging better to their needs.

Reworked requested changes.

Go change 064f34f (which exists in Go 1.19.2 and following) removed the
pagezero_size option from linker calls (because it is deprecated). This
expanded the problem that exists on darwin/arm64 as well as PIE builds
on darwin/amd64 to all darwin/amd64 builds.
This problem is described on: https://github.com/golang/go/issues/25841.
This commit extends the darwin/arm64 workaround to darwin/amd64.
Fixes#3194
- updated go/packages to support new export format
- rewrite testinline.go fixture because the compiler got too smart with
constant folding
- temporarily disable staticcheck on go1.20 because it doesn't support
the new export format.
- workaround for go.dev/cl/429601
Before 1.11 we used to read a bunch of runtime structures to determine
the runtime type of an interface variable. This had significant
dependencies on private structs of the Go runtime and the code is
broken for versions of Go after 1.17.
Remove all this code, since it is no longer used and doesn't work with
newer versions of Go anyway.
Fix cast to empty interface type. This is a workaround for a
discrepancy between how type names are serialized by the compiler vs
how type expressions are formatted by go/printer.
* Add support for windows/arm64

* fix testvariablescgo
* remove DerefGStructOffset
* derefrence gstructoffset in GStructOffset() if necessary
Go 1.19 also formats doc comments according to the new godoc syntax.
Some of our comments, especially unexported symbols did not conform to
the godoc syntax and therefore are mangled by 'go fmt'.
This PR runs 'go fmt' from go1.19 on everything and manually fixes the
problems.
