It then updates various spots in gdb to use this class, rather than a cleanup. It would be better overall to replace "struct value *" with a shared_ptr, maybe eliminating the need for this class (watchpoints would perhaps need some new mechanism as well).

The user of this class has the option to preserve the file instead, by calling the "keep" method. This patch then changes the spots in gdb that use unlink in a cleanup to use this class instead. In one spot I went ahead and removed all the cleanups from the function.

Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

It also changes evpy_emit_event not to steal a reference to its argument. This is simpler to do now that gdbpy_ref is in use; it's also a reasonable cleanup in its own right. While doing this I realized that evpy_emit_event should not be calling gdbpy_print_stack (all the outermost callers do this if needed), so I removed this as well. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-threadevent.c (create_thread_event_object): Use gdbpy_ref. * python/py-stopevent.c (create_stop_event_object): Simplify.

This class acts a bit like unique_ptr, but also a bit like shared_ptr (in that copies do what you might expect); I considered going solely with unique_ptr but it seemed quite strange to have a unique_ptr that actually manages a shared resource.

This is wrong since these functions do not expect to read a breakpoint instruction and can lead to invalid behavior. Use of raw memory in get_next_pcs_read_memory_unsigned_integer for example could lead to get_next_pc returning an invalid pc. Here's how this would happen: In non-stop: the user issues: thread 1 step& thread 2 step& thread 3 step& In a similar way as non-stop-fair-events.exp (threads are looping). GDBServer: linux_resume is called GDBServer has pending events, threads are not resumed and single-step breakpoint for thread 1 not installed. linux_wait_1 is called with a pending event on thread 2 at pc A GDBServer handles the event and calls proceed_all_lwps This calls proceed_one_lwp and installs single-step breakpoints on all the threads that need one. Now since thread 1 needs to install a single-step breakpoint and is at pc B (different than thread 2), a step-over is not initiated and get_next_pc is called to figure out the next instruction from pc B. However it may just be that thread 3 as a single step breakpoint at pc B. And thus get_next_pc fails. This situation is tested with non-stop-fair-events.exp. In other words, single-step breakpoints are installed in proceed_one_lwp for each thread. GDBserver proceeds two threads for resume_step, as requested by GDB, and the thread proceeded later may see the single-step breakpoints installed for the thread proceeded just now. Tested on gdbserver-native/-m{thumb,arm} no regressions. gdb/gdbserver/ChangeLog: * linux-aarch32-low.c (arm_breakpoint_kind_from_pc): Use target_read_memory. * linux-arm-low.c (get_next_pcs_read_memory_unsigned_integer): Likewise.
