[Bug python/12816] New: No 'pending' support for breakpoints created from Python

           Summary: No 'pending' support for breakpoints created from
                    Python
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: python
        AssignedTo: unassigned@sourceware.org
        ReportedBy: kevin.pouget@gmail.com


when one creates a gdb.Breakpoint object, s/he has no control on its pending
state:

> (gdb) python gdb.Breakpoint('send')
> No symbol table is loaded.  Use the "file" command.
> Breakpoint 4 (send) pending.

it would be convenient to 
1) specify if we allow or not the breakpoint to be pending
2) remove the two lines written by GDB
3) know whether the breakpoint has actually been set or is pending

(I should provide a solution for 3 soon)

the problem about 1) is:

(gdb) set breakpoint pending off
(gdb) py gdb.Breakpoint("nop")
Function "nop" not defined.
Breakpoint 7 (nop) pending.

Since gdb 7.12, gdb.Breakpoint has the (read-only) "pending" attribute.
Is more needed to resolve this ticket?

AFAIU, it doesn't.  This bug is about being able to decide whether to allow
pending breakpoints when creating a gdb.Breakpoint.  I would imagine a
parameter like:

  gdb.Breakpoint("my_function", allow_pending=True)

for example.

I belatedly discovered that a breakpoint created from Python
is always marked pending.  So maybe there's nothing really needed here.

I misread the bug and see it's asking for a "non-pending" option.
I guess that makes sense :)

I pushed my current hacks to my github, branch "submit/pr-py-12816-pending".
Needs rebasing and probably other work.
