Tankut Baris Aktemur 21e051b3d6 gdb/main: execute breakpoint commands for '-iex' and '-ex' commands ... Suppose we have the script file below: break main commands print 123 end run If started with this script file, GDB executes the breakpoint command: $ gdb -q -x myscript --args ./test Reading symbols from ./test... Breakpoint 1 at 0x114e: file test.c, line 2. Breakpoint 1, main () at test.c:2 2 return 0; $1 = 123 (gdb) However, if we remove the "run" line from the script and pass it with the '-ex' option instead, the command is not executed: $ gdb -q -x myscript_no_run --args ./test Reading symbols from ./test... Breakpoint 1 at 0x114e: file test.c, line 2. Starting program: /path/to/test Breakpoint 1, main () at test.c:2 2 return 0; (gdb) If the user enters a command at this point, the breakpoint command is executed, yielding weird output: $ gdb -q -x myscript_no_run --args ./test Reading symbols from ./test... Breakpoint 1 at 0x114e: file test.c, line 2. Starting program: /path/to/test Breakpoint 1, main () at test.c:2 2 return 0; (gdb) print "a" $1 = "a" $2 = 123 When consuming script files, GDB runs bp actions after executing a command. See `command_handler` in event-top.c: if (c[0] != '#') { execute_command (command, ui->instream == ui->stdin_stream); /* Do any commands attached to breakpoint we stopped at. */ bpstat_do_actions (); } However, for '-ex' commands, `bpstat_do_actions` is not invoked. Hence, the misaligned output explained above occurs. To fix the problem, add a call to `bpstat_do_actions` after executing a command. gdb/ChangeLog: 2020-12-07 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * main.c (catch_command_errors): Add a flag parameter; invoke `bpstat_do_actions` if the flag is set. (execute_cmdargs): Update a call to `catch_command_errors`. gdb/testsuite/ChangeLog: 2020-12-07 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.base/bp-cmds-run-with-ex.c: New file. * gdb.base/bp-cmds-run-with-ex.exp: New file. * gdb.base/bp-cmds-run-with-ex.gdb: New file. * gdb.gdb/python-interrupts.exp: Update the call to 'catch_command_errors' with the new argument. * gdb.gdb/python-selftest.exp: Ditto.		2020-12-07 09:10:51 +01:00
