From 731145cb171b848d564a696e81153166524eb35a Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 6 Dec 2012 18:59:57 +0000 Subject: [PATCH] 2012-12-06 Jens Elmenthaler PR mi/14741: * mi/mi-cmd-var.c (varobj_update_one): Take value of attribute "dynamic" and "displayhint" from printed child, not the root variable. * gdb.python/py-mi.exp: Correct expected results for attribute "dynamic" returned by -var-update. Add test case for correct handling of "diplayhint" for children of dynamic varobjs. * gdb.python/py-prettyprint.c (set_itme): New function. (bug_14741) New function. (main) Add call to bug_14741(). * gdb.python/py-prettyprint.py (class ArrayPrinter): New class. --- gdb/ChangeLog | 7 +++++++ gdb/mi/mi-cmd-var.c | 4 ++-- gdb/testsuite/ChangeLog | 11 +++++++++++ gdb/testsuite/gdb.python/py-mi.exp | 26 ++++++++++++++++++++++++-- gdb/testsuite/gdb.python/py-prettyprint.c | 19 ++++++++++++++++++- gdb/testsuite/gdb.python/py-prettyprint.py | 30 ++++++++++++++++++++++++++++++ 6 files changed, 92 insertions(+), 5 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 1bfbc7d..4f89004 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,10 @@ +2012-12-06 Jens Elmenthaler + + PR mi/14741: + * mi/mi-cmd-var.c (varobj_update_one): Take value of + attribute "dynamic" and "displayhint" from printed child, + not the root variable. + 2012-12-06 Joel Brobecker * aix-thread.c (getthrds): Fix type of 4th parameter. diff --git a/gdb/mi/mi-cmd-var.c b/gdb/mi/mi-cmd-var.c index dc47bc1..6416d7d 100644 --- a/gdb/mi/mi-cmd-var.c +++ b/gdb/mi/mi-cmd-var.c @@ -793,14 +793,14 @@ varobj_update_one (struct varobj *var, enum print_values print_values, ui_out_field_int (uiout, "new_num_children", varobj_get_num_children (r->varobj));
