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.c: Fix whitespace issuesAndreas Arnez2-949/+954

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. Tested on x86_64 native Linux. gdb/ChangeLog 2016-01-28 Keith Seitz <keiths@redhat.com> PR breakpoints/18303 * cp-namespace.c (cp_lookup_bare_symbol): Change assertion to look for "::" instead of simply ":".

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.

These tests should have been adjusted by f303dbd60d9c (Fix PR threads/19422 - show which thread caused stop), but clearly I had missed grepping for potential-fail cases. gdb/testsuite/ChangeLog 2016-03-09 Pedro Alves <palves@redhat.com> * gdb.threads/attach-into-signal.exp: Adjust to "Program received signal" -> "Thread NN received signal" output change. * gdb.threads/ia64-sigill.exp: Likewise. * gdb.threads/linux-dp.exp: Likewise. * gdb.threads/manythreads.exp: Likewise. * gdb.threads/pending-step.exp: Likewise. * gdb.threads/print-threads.exp: Likewise. * gdb.threads/sigstep-threads.exp: Likewise. * gdb.threads/staticthreads.exp: Likewise. * gdb.threads/tls.exp: Likewise.

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.
