From: Pedro Alves Date: Tue, 25 Mar 2014 11:45:53 +0000 (+0000) Subject: "source", foreground execution commands, and target-async X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d3839ede057ef077667978dbd065e7b5702c9176;p=binutils-gdb.git "source", foreground execution commands, and target-async Sourcing a GDB script that runs foreground execution commands in succession fails if the target can async: Breakpoint 1, main () at ../../../src/gdb/testsuite/gdb.base/source-execution.c:36 36 func1 (); (gdb) source ../../../src/gdb/testsuite/gdb.base/source-execution.gdb ../../../src/gdb/testsuite/gdb.base/source-execution.gdb:21: Error in sourced command file: Cannot execute this command while the selected thread is running. (gdb) FAIL: gdb.base/source-execution.exp: source source-execution.gdb That is, after a foreground execution command, GDB moves on to the following command immediately before waiting for the previous command to complete. https://sourceware.org/ml/gdb-patches/2011-09/msg00037.html (b4a14fd0) addressed this for command lists, Python's gdb.execute, etc., but missed "source". Fixed now in the same way. gdb/ 2014-03-25 Pedro Alves * cli/cli-script.c (script_from_file): Force the interpreter to sync mode. gdb/testsuite/ 2014-03-25 Pedro Alves Doug Evans * gdb.base/source-execution.c: New file. * gdb.base/source-execution.exp: New file. * gdb.base/source-execution.gdb: New file. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index c1231cab6ec..74e20a4b1ba 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2014-03-25 Pedro Alves + + * cli/cli-script.c (script_from_file): Force the interpreter to + sync mode. + 2014-03-24 Pierre Langlois * avr-tdep.c (avr_scan_prologue): Accept push r1 instruction for diff --git a/gdb/cli/cli-script.c b/gdb/cli/cli-script.c index 246fcc9fbb2..7dc1ba4b362 100644 --- a/gdb/cli/cli-script.c +++ b/gdb/cli/cli-script.c @@ -1667,6 +1667,9 @@ script_from_file (FILE *stream, const char *file) source_line_number = 0; source_file_name = file; + make_cleanup_restore_integer (&interpreter_async); + interpreter_async = 0; + { volatile struct gdb_exception e; diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index ba0471ab665..b7bc990754c 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,10 @@ +2014-03-25 Pedro Alves + Doug Evans + + * gdb.base/source-execution.c: New file. + * gdb.base/source-execution.exp: New file. + * gdb.base/source-execution.gdb: New file. + 2014-03-24 Doug Evans * gdb.linespec/macro-relative.exp: Mark the test as unsupported if diff --git a/gdb/testsuite/gdb.base/source-execution.c b/gdb/testsuite/gdb.base/source-execution.c new file mode 100644 index 00000000000..e7de1196886 --- /dev/null +++ b/gdb/testsuite/gdb.base/source-execution.c @@ -0,0 +1,41 @@ +/* This testcase is part of GDB, the GNU debugger. + + Copyright 2014 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.
