From fbb8f2990ccfa180274ab4a578818fe247823540 Mon Sep 17 00:00:00 2001 From: Phil Muldoon Date: Fri, 10 Jul 2009 10:35:17 +0000 Subject: 2009-07-10 Phil Muldoon * python/python-internal.h (apply_varobj_pretty_printer): Update definition. (python_string_to_target_python_string): Add definition. * python/python-utils.c (unicode_to_encoded_python_string) (unicode_to_target_python_string) (python_string_to_target_python_string): New Functions. * python/python-prettyprint.c (pretty_print_one_value): Likewise. (print_string_repr): Refactor to logic to account for PyObject returned strings. (apply_varobj_pretty_printer): Likewise. * python/python-value.c (valpy_string): Parse length keyword. Use length keyword in LA_GET_STRING. * varobj.c (value_get_print_value): Refactor logic to account for PyObject returned strings. * c-lang.c (c_get_string): If the length parameter is specified, use that. Return value in characters. Update comments. * language.h: Update c_get_string prototype comments. 2009-07-10 Phil Muldoon * gdb.texinfo (Values From Inferior): Add length parameter description. 2009-07-10 Phil Muldoon * gdb.python/python-prettyprint.c: Add counted null string structure. * gdb.python/python-prettyprint.exp: Print null string. Test for embedded nulls. * gdb.python/python-prettyprint.py (pp_ns): New Function. * gdb.python/python-value.exp (test_value_in_inferior): Add variable length string fetch tests. * gdb.python/python-value.c (main): Add strings for string fetch tests. --- gdb/language.h | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) (limited to 'gdb/language.h') diff --git a/gdb/language.h b/gdb/language.h index e5f80ab..ba37faa 100644 --- a/gdb/language.h +++ b/gdb/language.h @@ -284,10 +284,15 @@ struct language_defn int (*la_pass_by_reference) (struct type *type); /* Obtain a string from the inferior, storing it in a newly allocated - buffer in BUFFER, which should be freed by the caller.
