From 8f28f5226e56f018d5dec05522124f868ec86081 Mon Sep 17 00:00:00 2001 From: Phil Muldoon Date: Thu, 29 Aug 2013 10:06:18 +0000 Subject: [PATCH] 2013-08-29 Phil Muldoon * python/py-framefilter.c (py_print_frame): Remove usage of PyString_AsString. Use python_string_to_host_string instead. Refactor function to work with a string as a new allocation instead of a pointer. (py_print_frame): Ditto. * python/lib/gdb/frames.py (return_list): Cain iterators together instead of adding them as a list. (_sort_list): Call return_list, and remove duplicate code. (execute_frame_filters): Convert iterator to a list with list(). * python/lib/gdb/command/frame_filters.py (SetFrameFilterPriority._set_filter_priority): Convert priority attribute to an integer. * python/lib/gdb/FrameIterator.py (FrameIterator.next): Define wrapper function __next__. * python/lib/gdb/FrameDecorator.py: If basestring not defined, define as "str". 2013-08-29 Phil Muldoon * gdb.python/py-framefilter.py (FrameFilter.filter): Check itertools for imap attribute. Otherwise use map(). (ElidingIterator): Define wrapper function __next__. * gdb.python/py-framefilter-mi.exp: Do not use execfile, use exec (open (read ())) instead. * gdb.python/py-framefilter.exp: Ditto. * gdb.python/py-arch.exp: Update print based test to Python 3.x compliance. * gdb.python/py-frame.exp: Ditto. * gdb.python/py-type.exp: Ditto. --- gdb/ChangeLog | 19 +++++++++++++++ gdb/python/lib/gdb/FrameDecorator.py | 9 +++++++ gdb/python/lib/gdb/FrameIterator.py | 6 +++++ gdb/python/lib/gdb/command/frame_filters.py | 5 +++- gdb/python/lib/gdb/frames.py | 33 +++++++++++++------------- gdb/python/py-framefilter.c | 10 ++++++-- gdb/testsuite/ChangeLog | 13 ++++++++++ gdb/testsuite/gdb.python/py-arch.exp | 14 +++++------ gdb/testsuite/gdb.python/py-frame.exp | 2 +- gdb/testsuite/gdb.python/py-framefilter-mi.exp | 2 +- gdb/testsuite/gdb.python/py-framefilter.exp | 4 ++-- gdb/testsuite/gdb.python/py-framefilter.py | 16 +++++++++++-- gdb/testsuite/gdb.python/py-type.exp | 32 ++++++++++++------------- 13 files changed, 116 insertions(+), 49 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 38ca053..23ca768 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,24 @@ 2013-08-29 Phil Muldoon + * python/py-framefilter.c (py_print_frame): Remove usage of + PyString_AsString.
