In v2: - Addressed Tom's feedback on patch #4. - Rebased onto current HEAD. - Retested. --- This series provides a Python API which can be used to find missing objfiles when opening a core file. This is very similar in spirit to the already existing code that provides a Python API for finding missing debug information. The first patch in this series cleans up the message that debuginfod produces. This is only relevant because the cleanup changes which filenames are passed around, these same filenames are then passed into the new Python API. Patch #2 is a refactoring. Patch #3 adds the new extension language API on the GDB core side. Patch #4 adds the Python side of the same API. For reference, see these commits for when the missing debug files Python API was added: * 8f6c452b5a4 gdb: implement missing debug handler hook for Python * 661d98a3331 gdb: add an extension language hook for missing debug info Thanks, Andrew --- Andrew Burgess (4): gdb: use mapped file information to improve debuginfod text gdb: rename ext_lang_missing_debuginfo_result gdb: add extension hook ext_lang_find_objfile_from_buildid gdb/python: implement Python find_exec_by_build_id hook gdb/NEWS | 24 + gdb/build-id.c | 88 ++- gdb/build-id.h | 3 +- gdb/corelow.c | 63 +- gdb/data-directory/Makefile.in | 4 +- gdb/debuginfod-support.c | 4 +- gdb/doc/gdb.texinfo | 1 + gdb/doc/python.texi | 194 ++++++- gdb/extension-priv.h | 15 +- gdb/extension.c | 26 +- gdb/extension.h | 30 +- gdb/python/lib/gdb/__init__.py | 110 +++- .../{missing_debug.py => missing_files.py} | 135 +++-- gdb/python/lib/gdb/missing_debug.py | 161 +----- gdb/python/lib/gdb/missing_files.py | 204 +++++++ gdb/python/lib/gdb/missing_objfile.py | 67 +++ gdb/python/py-progspace.c | 26 +- gdb/python/python.c | 120 +++- gdb/solib.c | 3 +- gdb/symfile-debug.c | 2 +- .../gdb.debuginfod/corefile-mapped-file.exp | 2 +- .../gdb.debuginfod/solib-with-soname.exp | 2 +- .../gdb.python/py-missing-objfile-lib.c | 35 ++ gdb/testsuite/gdb.python/py-missing-objfile.c | 49 ++ .../gdb.python/py-missing-objfile.exp | 544 ++++++++++++++++++ .../gdb.python/py-missing-objfile.py | 158 +++++ 26 files changed, 1787 insertions(+), 283 deletions(-) rename gdb/python/lib/gdb/command/{missing_debug.py => missing_files.py} (54%) create mode 100644 gdb/python/lib/gdb/missing_files.py create mode 100644 gdb/python/lib/gdb/missing_objfile.py create mode 100644 gdb/testsuite/gdb.python/py-missing-objfile-lib.c create mode 100644 gdb/testsuite/gdb.python/py-missing-objfile.c create mode 100644 gdb/testsuite/gdb.python/py-missing-objfile.exp create mode 100644 gdb/testsuite/gdb.python/py-missing-objfile.py base-commit: a723c56efb07c4f8b3f6a3ed4b878a2f8f5572cc
