Mostly to avoid the default filename completions to flags that don't
operate on filenames. Then again, mark ones that do explicitly as
such, and add more specific completions for a number of other cases,
too.
We had a few checks left over for the TRAVIS variable that detected if
we were running under the TravisCI build system.
This variable hasn't been set since 2020.
* proc: correctly update local variables after continue
At various point during the execution of the call injection protocol
the process is resumed and the call injection goroutine could migrate
to a different thread, we must make sure to update our local variables
correctly after every point where the target program is resumed.

* go.mod: update golang.org/x/tools
Go 1.22 broke golang.org/x/tools/packages
* cmd/dlv: disable TestStaticcheck with go1.22
Go 1.22 is not yet supported by staticcheck.
Due to some very old mistakes too many of Delve's flags are declared as
persistent on cobra's root command. For example the headless flag is a
global flag but does not apply to connect, dap or trace; the backend
flag does not apply to replay, core and dap; etc.
Almost all global flags should have been declared as local flags on
individual subcommands. Unfortunately we can not change this without
breaking backwards compatibility, for example:
dlv --headless debug
would not parse if headless was a flag of debug instead of a global
flag.
Instead we alter usage function and the markdown generation script to
strategically hide the flags that don't apply.
Fixes#2361
Adds a waitfor option to 'dlv attach' that waits for a process with a
name starting with a given prefix to appear before attaching to it.
Debugserver on macOS does not support follow-fork mode, but has this
feature instead which is not the same thing but still helps with
multiprocess debugging somewhat.
* logflags,proc: flag to log stacktrace execution
Add a log flag to write logs about what the stacktracer does.
* proc: read context from sigtrampgo, fixes TestCgoStacktrace2 on 1.21
Changes stacktrace code to read the signal context from the arguments
of sigtrampgo.
Also changes the automatic fatalthrow breakpoint for go 1.21.
In combination these two changes fix TestCgoStacktrace2 on Go 1.21 on
various platforms.
Uprobes get automatically cleaned and removed when the reference to
the Link object is lost. Hold a reference to any active Uprobe Link
for duration of Delve execution and ensure they are cleaned up
at exit.
Fixes ebpf probes don't work after time.Sleep() #3227
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...
Using a fixed path as the default output binary means that executing
Delve twice in the same directory will cause the second invocation to
overwrite the output binary of the first instance of Delve, making the
restart command not work correctly.
Fixes#3345
We currently return an error when the command exits because a process
exited error is always returned. Detect this like we do in other code
paths to return a 0 exit code instead of nonzero which indicates the
command itself failed and can confuse other tools.
Fixes a bug where we cannot get locals (including arguments and return
values) from a given scope because the line number state machine ends up
in an invalid state because of this parameter being set to false.
When 'dlv test' is called with a list of files it should match the
behavior of 'go test' and chdir to the directory where the go files are
(if they are all in the same directory).
Fixes#3230
- use PT_SUSPEND/PT_RESUME to control running threads in
resume/stop/singleStep
- change manual stop signal from SIGTRAP to SIGSTOP to make manual stop
handling simpler
- change (*nativeProcess).trapWaitInternal to suspend newly created
threads when we are stepping a thread
- change (*nativeProcess).trapWaitInternal to handle some unhandled
stop events
- remove misleading (*nativeProcess).waitFast which does not do
anything different from the normal wait variant
- rewrite (*nativeProcess).stop to only set breakpoints for threads of
which we have received SIGTRAP
- rewrite (*nativeThread).singleStep to actually execute a single
instruction and to properly route signals

- 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
Go 1.19 is broken on linux/386 with some C compilers, this is a
workaround for our build script. See:
https://github.com/golang/go/issues/52919
Also fix TestBuild if the first message reported by delve is not the
message that indicates the server is listening.
This patch improves the output of the trace subcommand by
adding better line breaks, adding goroutine info to the
return statement, and removing unnecessary output.
This patch removes the old error-prone way of tracking
whether the tracepoint is for a function entry or
return. Instead of trying to guess, let the data structure
simply tell us directly.
The ebpf implementations uses cgo, but only to access some C struct
definitions. Instead of using cgo simply duplicate the defintion of
those two structs in Go and add a test to check that the duplicate
definitions remain synchronized.
Fixes#2827
1. return an error when SetUProbe fails, while creating ebpf tracepoints
2. if no tracepoint can be set for 'dlv trace' exit early
3. never leave the traced program running
4. fix typo in description of --ebpf flag
Fixes#3006
