Make the 'list' command succeed for file:line expressions that don't
map to any instruction.
Adds an argument to the FindLocations API call that makes FindLocations
return if the expression can be parsed, even if it doesn't end up
matching any instruction in debug_line.
Adds a '-r' option to the 'restart' command (and to the Restart API)
that re-records the target when using rr.
Also moves the code to delete the trace directory inside the gdbserial
package.
Add options to start a stacktrace from the values saved in the
runtime.g struct as well as a way to disable the stackSwitch logic and
just get a normal stacktrace.
If a closure captures a variable but also defines a variable of the
same name in its root scope the shadowed flag would, sometimes, not be
appropriately applied to the captured variable.
This change:
1. sorts the variable list by depth *and* declaration line, so that
closure captured variables always appear before other root-scope
variables, regardless of the order used by the compiler
2. marks variable with the same name as shadowed even if there is only
one scope at play.
This fixes the problem but as a side effect:
1. programs compiled with Go prior to version 1.9 will have the
shadowed flag applied arbitrarily (previously the shadowed flag was not
applied at all)
2. programs compiled with Go prior to versoin 1.11 will still exhibit
the bug, as they do not have DeclLine information.

* scripts: use relative path in gen-cli-docs.go
Makes gen-cli-docs.go work outside GOPATH.
* Documentation,cmd/dlv: tidy up --help output
The description of --log-dest, --log-output and --backend is very
verbose and messes up the output of --help, move it to two "additional
help" subcommands.

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
The location specified '<fnname>:0' could be used to set a breakpoint
on the entry point of the function (as opposed to locspec '<fnname>'
which sets it after the prologue).
Setting a breakpoint on an entry point is almost never useful, the way
this feature was implemented could cause it to be used accidentally and
there are other ways to accomplish the same task (by setting a
breakpoint on the PC address directly).
Before doing anything check that the version of Go is compatible with
the current version of Delve.
This will improve the error message in the case that another change as
disruptive as Go1.11 dwarf compression, happens.
* *: use loglevel to control what gets logged instead of output redirection
This stops logrus from doing all the formatting just to discard it
immediately afterwards.
* logflags: replace default formatter of logrus
The default formatter of logrus emits logs in two different formats
depending on whether or not the output is going to a terminal. The
output format for non-terminals is indented to be machine readable, but
we mostly read logs ourselves and the excessive quoting makes that
format unreadable.
When outputting to terminals it uses ANSI escape codes unconditionally,
without checking whether the terminal it is connected to actually
supports colors.
This commit replaces the default formatter with a much simpler
formatter that always uses a more readable format, doesn't use colors
and places the key-value pairs at the beginning of the line (which is a
better match for how we use them).
* cmd/dlv: add command line options to redirect logs
Adds two options, --log-to-file and --log-to-fd, to redirect logs to a
file or to a file descriptor.
When one of those two options is specified the "API server listening
at:" message will also be redirected to the specified file/file
descriptor.
This allows clients that want to use the "API server listening at:"
message to do so even if they want to redirect the target's stdout to
another file or device.
Implements #1179, #1523
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.
Minidumps are the windows equivalent of unix core files.
This commit updates pkg/proc/core so that it can open and read windows
minidumps.
Updates #794
Adds an --exec flag for the trace subcommand allowing users to specify a
pre-compiled binary to exec and trace.
Also adds a --test flag as a convienance for compiling and tracing a
test binary.
Fixes#1073
The name "where" may confuse users into thinking that this parameter
actually does something where in fact it's just arbitrary text used to
identify the checkpoint.
Fixes#1373
On macOS 10.14 Apple changed the command line tools so that system
headers now need to be manually installed.
Instead of adding one extra install step to the install procedure add a
build tag to allow compilation of delve without the native backend on
macOS. By default (i.e. when using `go get`) this is how delve will be
compiled on macOS, the make script is changed to enable compiling the
native backend if the required dependencies have been installed.
Insure that both configuration still build correctly on Travis CI and
change the documentation to describe how to compile the native backend
and that it isn't normally needed.
Fixes#1359
With this syntax users do not need to type the concrete type of an
interface variable to access its contents. This also sidesteps the
problem where the serialization of a type by go/printer is different
from the one used for debug_info type names.
Updates #1328
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
