2013-04-10Accept "set foo unlimited" in integer/uinteger/zuinteger_unlimited commands.Pedro Alves19-55/+236
Currently, several commands take "0" or "-1" to mean "unlimited". "show" knows when to print "unlimited": (gdb) show height Number of lines gdb thinks are in a page is 45. (gdb) set height 0 (gdb) show height Number of lines gdb thinks are in a page is unlimited. However, the user can't herself specify "unlimited" directly: (gdb) set height unlimited No symbol table is loaded. Use the "file" command. (gdb) This patch addresses that, by adjusting the set handler for all integer/uinteger/zuinteger_unlimited commands to accept literal "unlimited". It also installs a completer. Presently, we complete on symbols by default, and at <http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've shown a WIP prototype that tried to keep that half working in these commands. In the end, it turned out to be more complicated than justifiable, IMO. It's super rare to want to pass the value of a variable/symbol in the program to a GDB set/show knob. That'll still work, it's just that we won't assist with completion anymore. This patch just sticks with the simple, and completes on "unlimited", and nothing else. This simplification means that "set he<tab><tab>" is all it takes to get to: "set height unlimited" The patch then goes through all integer/uinteger/zuinteger_unlimited commands in the tree, and updates both the online help and the manual to mention that "unlimited" is accepted in addition to 0/-1. In the cases where the command had no online help text at all, this adds it. I've tried to make the texts read in a way that "unlimited" is suggested before "0" or "-1" is.

2013-04-10make -gdb-exit call disconnect_tracing too, and don't lose history if the ↵Pedro Alves6-34/+76
target errors on "quit" Gareth mentions in PR gdb/15275: "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing() and therefore exits correctly." It should, so to get out of tfind mode, as quit may detach instead of kill, and we don't want to confuse the memory/register accesses etc. of the detach process. So we should push down the disconnect tracing bits at least to quit_force. But we can't as is, as that would swallow the error thrown by answering "no" to: Trace is running but will stop on detach; detach anyway? (y or n) So to address that, we split disconnect_tracing in two. One part that does the query, and another part that does the rest, and we make quit_force call the latter. Looking at quit_force, it does several things, some of which are a bit independent of the others. It first kills/detaches, and then writes history, and then runs the final cleanups. It seems better to me to do each of these things even if the previous thing throws. E.g., as is, if something throws while detaching, then we skip writing history.
