2016-03-17PR remote/19496, timeout in forking-threads-plus-bkptPedro Alves3-18/+34
This patch addresses a failure in gdb.threads/forking-threads-plus-breakpoint.exp: FAIL: gdb.threads/forking-threads-plus-breakpoint.exp: cond_bp_target=1: detach_on_fork=on: inferior 1 exited (timeout) Cause: A fork event was reported to GDB before GDB knew about the parent thread, followed immediately by a breakpoint event in a different thread. The parent thread was subsequently added via remote_notice_new_inferior in process_stop_reply, but when the thread was added the thread_info.state was set to THREAD_STOPPED. The fork event was then handled correctly, but when the fork parent was resumed via a call to keep_going, the state was unchanged. The breakpoint event was then handled, which caused all the non-breakpoint threads to be stopped. When the breakpoint thread was resumed, all the non-breakpoint threads were resumed via infrun.c:restart_threads. Our old fork parent wasn't restarted, because it still had thread_info.state set to THREAD_STOPPED. Ultimately the program under debug hung waiting for a pthread_join while the old fork parent was stopped forever by GDB. Fix: Since this is non-stop, then the bug is that the thread should have been added in THREAD_RUNNING state. Consider that infrun may be pulling target events out of the target_ops backend into its own event queue, but, not process them immediately. E.g., infrun may be stopping all threads temporarily for a step-over-breakpoint operation for thread A (stop_all_threads). The waitstatus of all threads is thus left pending in the thread structure (save_status), including the fork event of thread B. Right at this point, if the user does "info threads", that should show thread B (the fork parent) running, not stopped, even if internally, gdb is holding it paused for a little bit. Thus if in non-stop mode, always add new threads in the external user-visible THREAD_RUNNING state. Change remote_notice_new_inferior to accept the internal executing state of the thread instead, with EXECUTING set to 1 when we discover a thread that is running on the target (such as through remote_update_thread_list), and 0 when the thread is really paused (such as when we see a stop reply). Tested on x86_64 Linux and Nios II Linux target with x86 Linux host. gdb/ChangeLog: 2016-03-17 Pedro Alves <palves@redhat.com> Don Breazeal <donb@codesourcery.com> PR remote/19496 * infcmd.c (notice_new_inferior): Use the 'leave_running' argument instead of checking the 'non_stop' global. * remote.c (remote_add_thread): New parameter 'executing'.

2016-03-17S390: Add syscall info for syscalls up to 374Andreas Arnez3-0/+56
Represent new Linux syscalls for s390 and s390x in GDB's syscall info. Add the syscalls from 355 (userfaultfd) up to 374 (mlock2) as well as the previously reserved NUMA syscalls 268-270, 287, and 310. gdb/ChangeLog: * syscalls/s390-linux.xml: Add NUMA syscalls and new syscalls up to 374. * syscalls/s390x-linux.xml: Likewise.
2016-03-17S390: Fix output path for s390-multiarch test caseAndreas Arnez2-5/+9
Since test artifacts are organized in a directory hierarchy, the s390-multiarch test case is not executed correctly any more. This is because it uses an obsolete way of constructing the output paths. This fix invokes standard_testfile instead. gdb/testsuite/ChangeLog: * gdb.arch/s390-multiarch.exp: Use standard_testfile instead of maintaining separate logic for constructing the output path.
2016-03-17linux-record: Simplify with record_mem_at_reg()Andreas Arnez2-414/+170
The function record_linux_system_call() often records a memory area whose address is contained in a register. So far this required two function calls: one for fetching the register value, and another one for recording the memory area. These two function calls are now merged into a new local helper function, and all occurrences are adjusted. This reduces the source code and makes it more readable. gdb/ChangeLog: * linux-record.c (record_mem_at_reg): New helper function. (record_linux_system_call): Exploit new helper function where applicable.

2016-03-17linux-record: Fix bad fall-through for pipe/pipe2Andreas Arnez2-0/+7
This patch added handling for some syscalls to linux-record.c: https://sourceware.org/ml/gdb-patches/2015-10/msg00452.html But for both `pipe' and `pipe2' the patch lacks a statement after an `if', such that the following `break' is interpreted as the `if'-body instead. This adds the missing (return-) statements for the conditionals. gdb/ChangeLog: * linux-record.c (record_linux_system_call): Add missing return statements to handling of pipe and pipe2 syscalls.

2016-03-16PR remote/19496, interrupted syscall in forking-threads-plus-bkptDon Breazeal3-14/+33
This patch addresses "fork:Interrupted system call" (or wait:) failures in gdb.threads/forking-threads-plus-breakpoint.exp. The test program spawns ten threads, each of which do ten fork/waitpid sequences. The cause of the problem was that when one of the fork children exited before the corresponding fork parent could initiate its waitpid for that child, a SIGCHLD and/or SIGSTOP was delivered and interrupted a fork or waitpid in another thread. The fix was to wrap the system calls in a loop to retry the call if it was interrupted, like: do { pid = fork (); } while (pid == -1 && errno == EINTR); Since this is a Linux-only test I figure it is OK to use errno and EINTR. I tried a number of alternative fixes using SIG_IGN, SA_RESTART, pthread_sigblock, and bsd_signal, but none of these worked as well. Tested on Nios II Linux target with x86 Linux host. gdb/testsuite/ChangeLog: 2016-03-16 Don Breazeal <donb@codesourcery.com> * gdb.threads/forking-threads-plus-breakpoint.c (thread_forks): Retry fork and waitpid on interrupted system call errors. * gdb.threads/forking-threads-plus-breakpoint.exp: (do_test): Use with_timeout_factor to increase timeout to 90.

2016-03-15PR 18303, Tolerate malformed input for lookup_symbol-called functionsDon Breazeal10-182/+433
lookup_symbol is often called with user input. Consequently, any function called from lookup_symbol{,_in_language} should attempt to deal with malformed input gracefully. After all, malformed user input is not a programming/API error. This patch does not attempt to find/correct all instances of this. It only fixes locations in the code that trigger test suite failures. This patch fixes PR breakpoints/18303, "Assertion: -breakpoint-insert with windows paths of file in non-current directory". The patch includes three new tests related to this. One is just gdb.linespec/ls-errs.exp copied and converted to use C++ instead of C, and to add a case using a file name containing a Windows-style logical drive specifier. The others include an MI test to provide a regression test for the specific case reported in PR 18303, and a C++ test for proper error handling of access to a program variable when using a file scope specifier that refers to a non-existent file.

2016-03-10Add $_as_string convenience functionSimon Marchi9-0/+145
This patch is a follow-up to "Add printf format specifier for printing enumerator": https://sourceware.org/ml/gdb-patches/2016-02/msg00144.html Instead of having a solution specific to the printf command, Pedro suggested adding a general purpose function $_as_string() that would cover this use case and more. So, in order to print the textual label of an enum, one can use: (gdb) printf "Visiting node of type %s\n", $_as_string(node) Visiting node of type NODE_INTEGER gdb/ChangeLog: * data-directory/Makefile.in (PYTHON_FILE_LIST): Install gdb/function/as_string.py. * python/lib/gdb/function/as_string.py: New file. * NEWS: Mention the new $_as_string function. gdb/testsuite/ChangeLog: * gdb.python/py-as-string.exp: New file. * gdb.python/py-as-string.c: New file. gdb/doc/ChangeLog: * gdb.texinfo (Convenience Functions): Document $_as_string.

2016-03-09Command line input handling TLCPedro Alves5-318/+219
I didn't manage to usefully split this further into smaller independent pieces, so: - Use "struct buffer" more. - Split out the responsibility of composing a complete command line from multiple input lines split with backslash ( E.g.: (gdb) print \ 1 + \ 2 $1 = 3 (gdb) ) to a separate function. Note we don't need the separate readline_input_state and more_to_come globals at all. They were just obfuscating the logic. - Factor out the tricky mostly duplicated code in command_line_handler and command_line_input. gdb/ChangeLog 2016-03-09 Pedro Alves <palves@redhat.com> * event-top.c (more_to_come): Delete. (struct readline_input_state): Delete. (readline_input_state): Delete. (get_command_line_buffer): New function. (command_handler): Update comments. Don't handle NULL commands here. Do not execute commented lines. (command_line_append_input_line): New function. (handle_line_of_input): New function, partly based on command_line_handler and command_line_input. (command_line_handler): Rewrite. * event-top.h (command_handler): New declaration. (command_loop): Defer command execution to command_handler. (command_line_input): Update comments. Simplify, using struct buffer and handle_line_of_input. * top.h (struct buffer): New forward declaration. (handle_line_of_input): New declaration.
2016-03-09Simplify saved_command_line handlingPedro Alves5-21/+19
There doesn't seem to be much point in trying to reuse this buffer. Prefer simplicity instead. (In case you're wondering whether this fixes an off-by-one: linelength is misnamed; it's really a size including terminating null char.) gdb/ChangeLog: 2016-03-09 Pedro Alves <palves@redhat.com> * event-top.c (command_line_handler): Use xfree + xstrdup instead of xrealloc + strcpy. * main.c (captured_main): Use xstrdup instead of xmalloc plus manual clear. * top.c (saved_command_line): Rewrite comment. (saved_command_line_size): Delete. (command_line_input): Use xfree + xstrdup instead of xrealloc + strcpy. * top.h (saved_command_line_size): Delete declaration.
