2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-12-02gdb, include: replace pragmas with DIAGNOSTIC macros, fix build with g++ 4.8Simon Marchi1-3/+3
When introducing this code, I forgot that we had some macros for this. Replace some "manual" pragma diagnostic with some DIAGNOSTIC_* macros, provided by include/diagnostics.h. In diagnostics.h: - Add DIAGNOSTIC_ERROR, to enable a diagnostic at error level. - Add DIAGNOSTIC_ERROR_SWITCH, to enable -Wswitch at error level, for both gcc and clang. Additionally, using DIAGNOSTIC_PUSH, DIAGNOSTIC_ERROR_SWITCH and DIAGNOSTIC_POP seems to misbehave with g++ 4.8, where we see these errors: CXX ada-tasks.o /home/smarchi/src/binutils-gdb/gdb/ada-tasks.c: In function void read_known_tasks(): /home/smarchi/src/binutils-gdb/gdb/ada-tasks.c:998:10: error: enumeration value ADA_TASKS_UNKNOWN not handled in switch [-Werror=switch] switch (data->known_tasks_kind) ^ Because of the POP, the diagnostic should go back to being disabled, since it was disabled in the beginning, but that's not what we see here. Versions of GCC >= 5 compile correctly. Work around this by making DIAGNOSTIC_ERROR_SWITCH a no-op for GCC < 5. Note that this code (already as it exists in master today) enables -Wswitch at the error level even if --disable-werror is passed. It shouldn't be a problem, as it's not like a new enumerator will appear out of nowhere and cause a build error if building with future compilers. Still, for correctness, we would ideally want to ask the compiler to enable -Wswitch at its default level (as if the user had passed -Wswitch on the command-line). There doesn't seem to be a way to do this. Change-Id: Id33ebec3de39bd449409ea0bab59831289ffe82d
2021-11-22gdb: introduce target_waitkind_str, use it in target_waitstatus::to_stringSimon Marchi1-44/+22
I would like to print target_waitkind values in debug messages, so I think that a target_waitkind-to-string function would be useful. While at it, use it in target_waitstatus::to_string. This changes the output of target_waitstatus::to_string a bit, but I think it is for the better. The debug messages will show a string matching exactly the target_waitkind enumerator (minus the TARGET_WAITKIND prefix). As a convenience, make string_appendf return the same reference to string it got as a parameter. This allows doing this: return string_appendf (str, "foo"); ... keeping the code concise.

2021-11-22gdb: rename target_waitstatus_to_string to target_waitstatus::to_stringSimon Marchi1-9/+9
Make target_waitstatus_to_string a "to_string" method of target_waitstatus, a bit like we have ptid_t::to_string already. This will save a bit of typing. Change-Id: Id261b7a09fa9fa3c738abac131c191a6f9c13905
2021-10-21gdb, gdbserver: make target_waitstatus safeSimon Marchi1-10/+10
I stumbled on a bug caused by the fact that a code path read target_waitstatus::value::sig (expecting it to contain a gdb_signal value) while target_waitstatus::kind was TARGET_WAITKIND_FORKED. This meant that the active union field was in fact target_waitstatus::value::related_pid, and contained a ptid. The read signal value was therefore garbage, and that caused GDB to crash soon after. Or, since that GDB was built with ubsan, this nice error message: /home/simark/src/binutils-gdb/gdb/linux-nat.c:1271:12: runtime error: load of value 2686365, which is not a valid value for type 'gdb_signal' Despite being a large-ish change, I think it would be nice to make target_waitstatus safe against that kind of bug. As already done elsewhere (e.g. dynamic_prop), validate that the type of value read from the union matches what is supposed to be the active field. - Make the kind and value of target_waitstatus private. - Make the kind initialized to TARGET_WAITKIND_IGNORE on target_waitstatus construction. This is what most users appear to do explicitly. - Add setters, one for each kind. Each setter takes as a parameter the data associated to that kind, if any. This makes it impossible to forget to attach the associated data. - Add getters, one for each associated data type. Each getter validates that the data type fetched by the user matches the wait status kind. - Change "integer" to "exit_status", "related_pid" to "child_ptid", just because that's more precise terminology. - Fix all users. That last point is semi-mechanical. There are a lot of obvious changes, but some less obvious ones. For example, it's not possible to set the kind at some point and the associated data later, as some users did. But in any case, the intent of the code should not change in this patch. This was tested on x86-64 Linux (unix, native-gdbserver and native-extended-gdbserver boards). It was built-tested on x86-64 FreeBSD, NetBSD, MinGW and macOS. The rest of the changes to native files was done as a best effort. If I forgot any place to update in these files, it should be easy to fix (unless the change happens to reveal an actual bug).

2021-08-05gdb: target_waitstatus_to_string: print extra info for FORKED, VFORKED, EXECDSimon Marchi1-3/+22
Print the extra information contained in target_waitstatus for these events. For TARGET_WAITKIND_{FORKED,VFORKED}, the extra information is contained in related_pid, and is the ptid of the new process. For TARGET_WAITKIND_EXECD, it,s the exec'd path name in execd_pathname. Print it using the same format used for TARGET_WAITKIND_STOPPED and others. Here are sample outputs for all three events: [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) = [infrun] print_target_wait_results: 726890.726890.0 [process 726890], [infrun] print_target_wait_results: status->kind = vforked, related_pid = 726894.726894.0 [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) = [infrun] print_target_wait_results: 727045.727045.0 [process 727045], [infrun] print_target_wait_results: status->kind = forked, related_pid = 727049.727049.0 [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) = [infrun] print_target_wait_results: 727119.727119.0 [process 727119], [infrun] print_target_wait_results: status->kind = execd, execd_pathname = /usr/bin/ls Change-Id: I4416a74e3bf792a625a68bf26c51689e170f2184

2019-07-09Rename common to gdbsupportTom Tromey1-1/+1
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-04-01Fix internal error and improve 'set debug infrun 1'/target wait kind tracePhilippe Waroquiers1-2/+1
The test gdb.threads/watchthreads-reorder.exp verifies that the 'set debug infrun 1' debug output does not crash GDB. Under high load, the test can still cause a GDB internal error (see details below). This patch fixes this crash, and improves/factorises some wait kind traces. Tested on debian/amd64 + run one test with 'set debug infrun 1'. Changes compared to the first version: * Handles the suggestions of Kevin to trace the relevant elements of the wait status (this is done by calling target_waitstatus_to_string). * Some other changes to factorise wait status tracing. Note that using target_waitstatus_to_string instead of the 'locally printed' status kind strings means that debug trace that was using strings such as: "EXITED" or "TARGET_WAITKIND_EXITED" will now use what is printed by target_waitstatus_to_string e.g. "exited". gdb/ChangeLog 2019-04-01 Philippe Waroquiers <philippe.waroquiers@skynet.be> * infrun.c (stop_all_threads): If debug_infrun, always trace the wait status after wait_one, using target_waitstatus_to_string and target_pid_to_str. (handle_inferior_event): Replace various trace of wait status kind by a single trace. * gdb/gnu-nat.c (gnu_nat_target::wait): Replace local wait status kind image by target_waitstatus_to_string. * target/waitstatus.c (target_waitstatus_to_string): Fix obsolete comment.

This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2015-11-30Remote thread create/exit eventsPedro Alves1-0/+5
When testing with "maint set target-non-stop on", a few threading-related tests expose an issue that requires new RSP packets. Say there are 3 threads running, 1-3. If GDB tries to stop thread 1, 2 and 3, and then waits for their stops, but meanwhile say, thread 2 exits, GDB hangs forever waiting for a stop for thread 2 that won't ever happen. This patch fixes the issue by adding support for thread exit events to the protocol. However, we don't want these always enabled, as they're useless most of the time, and would slow down remote debugging. So I made it so that GDB can enable/disable them, and then made gdb do that around the cases that need it, which currently is only infrun.c:stop_all_threads. In turn, if we have thread exit events, then the extra "thread x exited" traffic slows down attach-many-short-lived-threads.exp enough that gdb has trouble keeping up with new threads that are spawned while gdb tries to stop existing ones. To fix that I added support for the counterpart thread created events too. Enabling those when we try to stop threads ensures that new threads never get a chance to themselves start new threads, killing the race. gdb/doc/ChangeLog: 2015-11-30 Pedro Alves <palves@redhat.com> * gdb.texinfo (Remote Configuration): List "set/show remote thread-events" command in configuration table.

2013-10-25infrun debug output: print enum gdb_signal symbol names instead of POSIX ↵Pedro Alves1-2/+4
signal names. The other day while debugging something related to random signals, I got confused with "set debug infrun 1" output, for it said: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 On GNU/Linux, 20 is SIGTSTP. For some reason, it took me a few minutes to realize that 20 is actually a GDB signal number, not a target signal number (duh!). In any case, I propose making GDB's output clearer here: One way would be to use gdb_signal_to_name, like already used elsewhere: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal SIGCHLD (20) but I think that might confuse someone too ("20? Why does GDB believe SIGCHLD is 20?"). So I thought of printing the enum string instead: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal GDB_SIGNAL_CHLD (20) Looking at a more complete infrun debug log, we had actually printed the (POSIX) signal name name a bit before: infrun: target_wait (-1, status) = infrun: 9300 [Thread 0x7ffff7fcb740 (LWP 9300)], infrun: status->kind = stopped, signal = SIGCHLD ... infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 So I'm now thinking that it'd be even better to make infrun output consistently use the enum symbol string, like so: infrun: clear_proceed_status_thread (Thread 0x7ffff7fca700 (LWP 25663)) infrun: clear_proceed_status_thread (Thread 0x7ffff7fcb740 (LWP 25659)) - infrun: proceed (addr=0xffffffffffffffff, signal=144, step=1) + infrun: proceed (addr=0xffffffffffffffff, signal=GDB_SIGNAL_DEFAULT, step=1) - infrun: resume (step=1, signal=0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGCHLD + infrun: status->kind = stopped, signal = GDB_SIGNAL_CHLD infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400700 - infrun: random signal 20 + infrun: random signal (GDB_SIGNAL_CHLD) infrun: random signal, keep going - infrun: resume (step=1, signal=20), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_CHLD), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGTRAP + infrun: status->kind = stopped, signal = GDB_SIGNAL_TRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400704 infrun: stepi/nexti infrun: stop_stepping GDB's signal numbers are public and hardcoded (see include/gdb/signals.h), so there's really no need to clutter the output with numeric values in some places while others not. Replacing the magic "144" with GDB_SIGNAL_DEFAULT in "proceed"'s debug output (see above) I think is quite nice. I posit that all this makes it clearer to newcomers that GDB has its own signal numbering (and that there must be some mapping going on).
