1. Don't use intelligent '#' in fmt of go because it is not always satisfying
for diffrent version of golang. Always keep one leading zero for octal and
one leading '0x' for hex manually. Then keep alignment for every byte.
2. Always keep addr alignment when the lens of two adjacent address are
different.
Update #1814.
Adds an optional scope prefix to the `regs` command which allows
printing registers for any stack frame (as long as they were somehow
saved). Issue #1838 is not yet to be closed since we are still not
recovering the registers of a segfaulting frame.
Updates #1838
According to #1800#1584#1038, `dlv` should enable the user to dive into
memory. User can print binary data in specific memory address range.
But not support for sepecific variable name or structures temporarily.(Because
I have no idea that modify `print` command.)
Close#1584.
Adds an API call that returns a list of packages contained in the
program and the files that were used to build them, and also a best
guess at which filesystem directory contained the package when it was
built.
This can be used by IDEs to map file paths if the debugging environment
doesn't match the build environment exactly.
This script re-runs a program until it fails or hits a breakpoint, it
is useful for debugging non-deterministic problems when used in
conjunction with rr.
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.
* terminal/command: add support for next [count]
* disallow negative counts.
* handle github comments, and regen docs.
* Fix the fact that we don't print the file info in the last step of the next count.
* Fix a typo, cleanup a few other observations.
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
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.
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
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
This pull request makes several changes to delve to allow headless
instancess that are started with the --accept-multiclient flag to
keep running even if there is no connected client. Specifically:
1. Makes a headless instance started with --accept-multiclient quit
after one of the clients sends a Detach request (previously they
would never ever quit, which was a bug).
2. Changes proc/gdbserial and proc/native so that they mark the
Process as exited after they detach, even if they did not kill the
process during detach. This prevents bugs such as #1231 where we
attempt to manipulate a target process after we detached from it.
3. On non --accept-multiclient instances do not kill the target
process unless we started it or the client specifically requests
it (previously if the client did not Detach before closing the
connection we would kill the target process unconditionally)
4. Add a -c option to the quit command that detaches from the
headless server after restarting the target.
5. Change terminal so that, when attached to --accept-multiclient,
pressing ^C will prompt the user to either disconnect from the
server or pause the target process. Also extend the exit prompt to
ask if the user wants to keep the headless server running.
Implements #245, #952, #1159, #1231
If the application being debugged imports two packages with the same
name (but different paths) there was no way to disambiguate the two,
since the character '/' can not appear inside a go identifier.
By allowing users to use a string literal as the package name a package
path can be specified.
* string to []rune
* string to []byte
* []rune to string
* []byte to string
* any pointer to uintptr
The string, []rune, []byte conversion pairs aligns this to the go
language.
The pointer -> uintptr conversion pair is symmetric to the uintptr ->
pointer that we already have.
Also lets the user specify any size for byte array types instead of
just the ones already used by the program, this can be used to read
arbitrary memory.
Fixes#548, #867
