Tom Tromey	4a5a194ae8	Reword gdb.GdbError text PR python/23108 points out that the gdb.GdbError documentation is somewhat difficult to find. The exception is apparently just mentioned in passing.

Tom Tromey	984ee559a2	Fix "set" handling of Python parameters It's long bothered me that setting a Python parameter from the CLI will print the "set" help text by default. I think usually "set" commands should be silent. And, while you can modify this behavior a bit by providing a "get_set_string" method, if this method returns an empty string, a blank line will be printed. This patch removes the "help" behavior and changes the get_set_string behavior to avoid printing a blank line. The code has a comment about preserving API behavior, but I don't think this is truly important; and in any case the workaround -- implementing get_set_string -- is trivial.

Simon Marchi	b89641bab5	python: Add qualified parameter to gdb.Breakpoint This patch adds the possibility to pass a qualified=True\|False parameter when creating a breakpoint in Python. It is equivalent to using -qualified in a linespec. The parameter actually accepts any Python value, and converts it to boolean using Python's standard rules for that (https://docs.python.org/3/library/stdtypes.html#truth). Unlike the -source/-line/-function/-label parameters, it is possible to use -qualified with a "normal" (non-explicit) linespec. Therefore, it is possible (unlike these other parameters) to use this new parameter along with the spec parameter. I updated the py-breakpoint.exp test. To be able to test multiple locations using a namespace, I had to switch the test case to compile as C++. If we really wanted to, we could run it as both C and C++, but omit the C++-specific parts when running it as C. gdb/ChangeLog: * location.h (string_to_event_location): Add match_type parameter. * location.c (string_to_event_location): Likewise. * python/py-breakpoint.c (bppy_init): Handle qualified parameter. gdb/doc/ChangeLog: * python.texi (Manipulating breakpoints using Python): Document qualified parameter to gdb.Breakpoint. gdb/testsuite/ChangeLog: * gdb.python/py-breakpoint.c (foo_ns::multiply): New function. * gdb.python/py-breakpoint.exp: Compile the test case as c++, call test_bkpt_qualified.

Simon Marchi	0b982d685e	python doc: Rework Breakpoint.__init__ doc I find the documentation of the gdb.Breakpoint constructor hard to read and not very informative, especially since we have added the new linespec parameters. There are multiple problems (some are subjective): - It's not clear that you should use either the spec string or the explicit arguments, not both. - It's not clear what combination of parameters you can use. - The big block of text describing the arguments is hard to read. - Currently, it seems like the "spec" argument is mandatory, even though it is not (if you use explicit linespec). - The square bracket nesting [arg1 [, arg2[, arg3]]] makes it seems like if you specify arg3, you must specify arg1 and arg2 (it's not the case here).

Tom Tromey	e0f3fd7c44	PR python/19293 - invalidate frame cache when unwinders change PR python/19293 notes that when a Python unwinder is disabled, the frame cache is not invalidated. This means that disabling an unwinder doesn't have any immediate effect -- but in my experience it's often the case that I want to enable or disable an unwinder in order to see what happens. This patch adds a new gdb.invalidate_cached_frames function and arranges for the relevant bits of library code to call it. I've only partially documented this function, considering a warning sufficient without going into all the reasons ordinary code should not call it. The name of the new function was taken from a comment in frame.h next to reinit_frame_cache. No new test as I think the updates to the existing test are sufficient to show that the code is working as intended.

Pedro Alves	5d5658a1d3	Per-inferior/Inferior-qualified thread IDs This commit changes GDB to track thread numbers per-inferior. Then, if you're debugging multiple inferiors, GDB displays "inferior-num.thread-num" instead of just "thread-num" whenever it needs to display a thread: (gdb) info inferiors Num Description Executable 1 process 6022 /home/pedro/gdb/tests/threads * 2 process 6037 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame 1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running) 1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running) 1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running) 2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running) 2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running) * 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running) (gdb) ... (gdb) thread 1.1 [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] (gdb) ... etc. You can still use "thread NUM", in which case GDB infers you're referring to thread NUM of the current inferior. The $_thread convenience var and Python's InferiorThread.num attribute are remapped to the new per-inferior thread number. It's a backward compatibility break, but since it only matters when debugging multiple inferiors, I think it's worth doing. Because MI thread IDs need to be a single integer, we keep giving threads a global identifier, _in addition_ to the per-inferior number, and make MI always refer to the global thread IDs. IOW, nothing changes from a MI frontend's perspective. Similarly, since Python's Breakpoint.thread and Guile's breakpoint-thread/set-breakpoint-thread breakpoint methods need to work with integers, those are adjusted to work with global thread IDs too. Follow up patches will provide convenient means to access threads' global IDs. To avoid potencially confusing users (which also avoids updating much of the testsuite), if there's only one inferior and its ID is "1", IOW, the user hasn't done anything multi-process/inferior related, then the "INF." part of thread IDs is not shown. E.g,.: (gdb) info inferiors Num Description Executable * 1 process 15275 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) add-inferior Added inferior 2 (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * NEWS: Mention that thread IDs are now per inferior and global thread IDs. * Makefile.in (SFILES): Add tid-parse.c.

Simon Marchi	a86c90e6ba	Clarify doc about memory read/write and non-8-bits addressable memory unit sizes New in v3: * Change RSP documentation as well. The m, M and X packets now use lengths in addressable memory units. New in v2: * Change wording: use byte for 8-bits chunks and addressable memory unit for the unit of data associated to a single address. * Introduce definition of addressable memory unit in the Memory section. This patch modifies the manual to clarify the MI, RSP and Python APIs in regard to reading/writing memory on architectures with addressable memory unit that are not 8 bits. Care is taken to use the word "addressable memory unit" or "memory unit" when referring to one piece of the smallest addressable size on the current architecture and the word "byte" when referring to an 8-bits data piece. For MI, -data-{read,write}-memory are not modified, since they are deprecated. gdb/doc/ChangeLog: * gdb.texinfo (GDB/MI Data Manipulation): Clarify usage of bytes and memory units for -data-{read,write}-memory-bytes.
