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
* Adds some links to the more relevant documentation pages on the main
README.md
* Adds a document informally describing how to write a client of delve
* Adds link to slides describing the architecture of delve
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.
We occasionally receive bug reports from users of VSCode-go and GoLand.
GoLand has its own way of capturing the packet exchange between itself
and delve but VSCode-go (supposedly) doesn't.
So far this hasn't been a problem since all bug reports were obvious
bugs on the plugin or easy to reproduce without VSCode-go, but it might
be helpful in the future to have a way to log the packet exchange
between dlv and a frontend.
This commit adds a --log-output option to enable logging of all rpc
messages and changes service/rpccommon accordingly.
Go1.11 uses the is_stmt flag of .debug_line to communicate which
assembly instructions are good places for breakpoints, we should
respect this flag.
These changes were introduced by:
* https://go-review.googlesource.com/c/go/+/102435/
Additionally when setting next breakpoints ignore all PC addresses that
belong to the same line as the one currently under at the cursor. This
matches the behavior of gdb and avoids stopping multiple times at the
heading line of a for statement with go1.11.
Change: https://go-review.googlesource.com/c/go/+/110416 adds the
prologue_end flag to the .debug_line section to communicate the end of
the stack-split prologue. We should use it instead of pattern matching
the disassembly when available.
Fixes#550
type of interfaces
'c7cde8b'.
Previously to 4e177bb99acc511897f9cdbfc6cbc50d92ae4725 it was possible
to use --log without arguments to enable logging, this commit reenables
that use case.
The new functionality of the --log flag moved to a new flag name
--logx.
Fixes#1188
I found this issue (https://github.com/derekparker/delve/issues/514) where user alexbrainman gave a very helpful answer. Adding this to the official install-guide might help a lot of users.
The formula is broken and produces an endless stream of duplicate bug
reports yet nobody steps up to fix it. Using the formula isn't
necessary and hasn't been in almost a year, the maintainers of delve
aren't using it and the original maintainer of the formula vacated.
* 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
* documentation: copied old documentation from wiki
* command: better online documentation
Help without arguments prints just a short summary for each command,
help followed by a command prints the command's syntax and a longer
explanation.
* documentation: automatically generate Documentation/cli/README.md
* documentation: headless invocation should specify --api-version=2
* documentation: More API documentation
* documentation: copied documentation from client.go to rpc2/server.go
Fixes#164
New API version with better backwards compatibility plus mechanism to
select the API version that a headless instance should use.
Adds service/test/cmd/typecheckrpc.go to type check the RPC interface.
I ran through these instructions and didn't notice that the
certificate I'd created appeared three times in the list I
was looking at. Emphasize where the trust setting is
enabled.
Going forward, all documentation should be placed in the Documentation
directory in the root of the project. This switch allows maintainers to
approve updates to documentation before they are committed, as opposed
to the pre-existing wiki which anybody could modify.
Currently the Documentation directory includes docs on building, usage,
and minimal docs around the API. This is just the initial commit, and
documentation will continue to improve over time.
Some changes have been made (and will continue to be made) to `cmd/dlv` to
ensure we can auto-generate documentation for all commands from the
newly provided script `scripts/gen-usage-docs.go`, which can be invoked
via `go run scripts/gen-usage-docs.go`.
Additionally, version has been split into its own package. This was a
bit of housekeeping related to the changes made the `cmd/dlv`.
