In order to support substituting a single file within
a larger package, and not substituting a directory wholesale,
this commit introduces the ability for SubstitutePath
to replace individual file paths if there is an exact match.
This behavior is backwards-compatible with the previous
configuration.
Fixes#3074
* proc,locspec: support setting breakpoints by func name on generic funcs
Changes proc.Function to parse function names correctly when they
contain instantiation lists and locspec to match generic functions.
* vendor: update golang.org/x/tools
The old version of golang.org/x/tools is incompatible with the new
iexport format.
* cmd/dlv,debugger: Improve dlv trace and trace command output
This patch improves the `dlv trace` subcommand output by reducing the
noise that is generated and providing clearer more concise information.
Also adds new tests closing a gap in our testing (we previously never
really tested this subcommand).
This patch also fixes the `dlv trace` REPL command to behave like the
subcommand in certain situations. If the tracepoint is for a function,
we now show function arguements and return values properly.
Also makes the overall output of the trace subcommand clearer.
Fixes#2027
