Unrecovered-panic and fatal-throw were no longer part of the breakpoint
list because starting in 37e44bf they were created before the logical
breakpoints map was switched to the logical breakpoints map of the
target group.
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
If a breakpoint has both a list of addresses and an expression prefer
the list of addresses, otherwise it is impossible to set breakpoint
with expressions that depend on the current scope, like 'break +0'
which sets a breakpoint on the current line.
Adds field to breakpoint struct to track how a breakpoint was
originally set, moves the logic for disabling and enabling a breakpoint
to proc.
This will allow creating suspended breakpoints that are automatically
enabled when a plugin is loaded. When follow exec mode is implemented
it will also be possible to automatically enable breakpoints (whether
or not they were suspended) on new child processes, as they are
spawned.
It also improves breakpoint restore after a restart, before this after
a restart breakpoints would be re-enabled using their file:line
position, for breakpoints set using a function name or a location
expression this could be the wrong location after a recompile.
Updates #1653
Updates #2551
Changes FindLocation to support multiple targets and adds an AddrPid
member to api.Breakpoint so that clients can set breakpoints by address
when multiple targets are connected (but at them moment this field is
ignored).
Updates #1653
Updates #2551
The logical breakpoints map was created as a side effect of
createUnrecoveredPanicBreakpoint or createFatalThrowBreakpoint, however
with an executable with incomplete debug info (that must be incomplete
in just the right way) both will fail and the logical breakpoint map
will never be created.
It's unknown how such an executable could be created, one easy way is
to debug a non-go executable.
Fixes#3114
Introduces a new TargetGroup abstraction that can be used to manage
multiple related targets.
No actual management of child processes is implemented here, this is
just a refactoring to make it possible to do that in the future.
