Date: Thu, 26 Mar 2015 12:47:06 -0400 Message-ID: <1427388426-26548-1-git-send-email-antoine.tremblay@ericsson.com> MIME-Version: 1.0 X-IsSubscribed: yes This patch fixes the "Format string required" error when trying to print a dprintf on a pending location when set via the MI interface even if the format string is entered correctly. This patch also adds a test case to check that issue called mi-dprintf-pending.exp. gdb/ChangeLog: PR breakpoints/16465 * breakpoint.c (create_breakpoint): Fix missing extra_string. gdb/testsuite/ChangeLog: PR breakpoints/16465 * gdb.mi/mi-dprintf-pending.c: New file. * gdb.mi/mi-dprintf-pending.exp: New test. * gdb.mi/mi-dprintf-pendshr.c: New file. --- gdb/breakpoint.c | 13 ++++- gdb/testsuite/gdb.mi/mi-dprintf-pending.c | 24 +++++++++ gdb/testsuite/gdb.mi/mi-dprintf-pending.exp | 77 +++++++++++++++++++++++++++++ gdb/testsuite/gdb.mi/mi-dprintf-pendshr.c | 27 ++++++++++ 4 files changed, 139 insertions(+), 2 deletions(-) create mode 100644 gdb/testsuite/gdb.mi/mi-dprintf-pending.c create mode 100644 gdb/testsuite/gdb.mi/mi-dprintf-pending.exp create mode 100644 gdb/testsuite/gdb.mi/mi-dprintf-pendshr.c diff --git a/gdb/breakpoint.c b/gdb/breakpoint.c index 0724a72..60f8213 100644 --- a/gdb/breakpoint.c +++ b/gdb/breakpoint.c @@ -9774,7 +9774,10 @@ create_breakpoint (struct gdbarch *gdbarch, b->addr_string = copy_arg; if (parse_arg) - b->cond_string = NULL; + { + b->cond_string = NULL; + b->extra_string = NULL; + } else { /* Create a private copy of condition string. */ @@ -9783,10 +9786,16 @@ create_breakpoint (struct gdbarch *gdbarch, cond_string = xstrdup (cond_string); make_cleanup (xfree, cond_string); } + /* Create a private copy of any extra string. */ + if (extra_string) + { + extra_string = xstrdup (extra_string); + make_cleanup (xfree, extra_string); + } b->cond_string = cond_string; + b->extra_string = extra_string; b->thread = thread; } - b->extra_string = NULL; b->ignore_count = ignore_count; b->disposition = tempflag ? disp_del : disp_donttouch; b->condition_not_parsed = 1; diff --git a/gdb/testsuite/gdb.mi/mi-dprintf-pending.c b/gdb/testsuite/gdb.mi/mi-dprintf-pending.c new file mode 100644 index 0000000..d6d8aac --- /dev/null +++ b/gdb/testsuite/gdb.mi/mi-dprintf-pending.c @@ -0,0 +1,24 @@ +/* This testcase is part of GDB, the GNU debugger. + + Copyright 2015 Free Software Foundation, Inc. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
