Allows for a user to specify the breakpoint condition directly
when creating the breakpoint. The new syntax looks like the
following:
```
break <name> <locspec> [if <expression>]
```
Also updates docs to include more examples and locspec description
instead of directing users to the online / source documentation.
With the glibc loader the link map entry for the static executable has
an empty name field and address equal to 0x0. This case was already
handled by the check in bininfo.go AddImage for names to be valid
paths.
With the musl loader however the first entry, corresponding to the
static executable, has a valid path with address equal to 0x0, since we
record a real address for the image corresponding to the static
executable this results in having two entries for the executable when
musl is used to link go programs.
Change the code scanning the debug link map so that the first entry is
skipped if it has address equal to zero.
Fixes#3617
* proc: make some type casts less counterintuitive
The interaction of type casts with load configuration is sometimes
counterintuitive. This commit changes the way it is performed so that
when converting slices to strings and vice versa the maximum size
corresponding to the target type is used (i.e. MaxStringLen when
converting slices to strings and MaxArrayValues when converting slices
to strings).
This doesn't fully solve the problem (conversions to []rune are
problematic and multiple chained type casts will still be confusing)
but removes the problem for the majority of practical uses.
Fixes#3595, #3539
* enable func call injection on delve for ppc64le
* Function call injection on Delve/ppc64le, modified DWARF encoding and decoding for floating point registers to make floatsum test work
* Function call injection on Delve/ppc64le cleanup
* skip PIE tests for function call injection on other packages
* Address review comments
* accounted for additional skipped PIE tests for function call injection
* Code cleanup and undoing revert of previous commit
* Enable function call injection only on 1.22 and above and some cleanup
* additional cleanup, go fmt run
* Debug function call tests fail on ppc64le/PIE mode adjusted the backup_test_health.md file accordingly
The current implementation assumes a specific command line interface
for opening an editor at a specific location within the source file.
This patch updates for different formats, namely the one used by the
editor 'hx'.
This command lists the packages included in the debugee.
The implementation utilizes "ListPackagesBuildInfo" RPC.
In order to support server-side filtering like `sources` and other
commands, expanded the ListPackagesBuildInfo RPC to take an optional
filter field.
Adds -chan option to the goroutines command to list only the goroutines
running on a specified channel.
Also when printing a variable if it is a channel also print the list of
goroutines that are waiting on it.
I searched the source code of Go, and found no usages of
"== (reflect.Value{})" and "!= (reflect.Value{})". I think
it's more idiomatic to use "IsValid" to check a zero Value.
Change FindLocation so it can return a substitute location expression
and propagate it to pkg/terminal/command.
When breakpoints are set using the syntax :<lineno> or +<lineno>
produce a substitute location expression that doesn't depend on having
a valid scope and can be used to restore the breakpoint.
Fixes#3423
Show the location expression that will be used to set a suspended
breakpoint in the breakpoints list.
Also change 'target' called without arguments to print a better error
message and 'target follow-exec' without the last argument to print the
state of follow-exec.
Adds a new starlark builtin 'help' that prints the list of available
builtins when called without arguments and help for the specified
builtin when passed an argument.
The help is autogenerated from godoc comments so it isn't always
exactly accurate for starlark (in particular we sometimes refer to the
In structs), but it's better than nothing.
This patch makes the time library available to Starlark scripts. This
library is one of the very few few that are built into starlark-go (the
others are json, math, proto).
I've played around with Starlark scripting today, and immediately I
wanted to measure how long certain computations take.
Read the command line of the main target process as well as any other
process Delve attaches to in follow exec mode.
The command line can be viewed using the 'target list' command.
In follow exec mode this command line is used to match the follow exec
regex to decide whether or not to attach to a child process.
On macOS or when using rr the list of arguments is not available for
attached processes since there is no way to use the gdb serial protocol
to read it.
Fixes#2242
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
Adds the ability to automatically debug child processes executed by the
target to the linux native backend.
This commit does not contain user interface or API to access this
functionality.
Updates #2551
Instead of using a fixed 100x30 window size query the operating system
for the exact size, also fixes a bug where the last line before calling
the pager is repeated twice.
This patch allows users to set a breakpoint even when the process has
exited. It will be left in a pending state until the process is
restarted.
Fixes#3242
