I recently learned that move constructors generally should be marked
"noexcept". This ensures that standard containers will move objects
when possible, rather than copy them.
This patch fixes the cases I could find. Note that implicitly-defined
or defaulted move constructors will automatically do what you'd
expect; that is, they are noexcept if all the members have noexcept
move constructors.
While doing this, I noticed a couple of odd cases where the move
constructor seemed to assume that the object being constructed could
have state requiring destruction. I've fixed these as well. See
completion_result and scoped_mmap.

Consider debugging the following C++ program:
struct object
{ int a; };
typedef object *object_p;
static int
get_value (object_p obj)
{
return obj->a;
}
int
main ()
{
object obj;
obj.a = 0;
return get_value (&obj);
}
Now in a GDB session:
(gdb) complete break get_value
break get_value(object*)
break get_value(object_p)
Or:
(gdb) break get_va<TAB>
(gdb) break get_value(object<RETURN>
Function "get_value(object" not defined.
Make breakpoint pending on future shared library load? (y or [n]) n
The reason this happens is that we add completions based on the
msymbol names and on the symbol names. For C++ both of these names
include the parameter list, however, the msymbol names have some
differences from the symbol names, for example:
+ typedefs are resolved,
+ whitespace rules are different around pointers,
+ the 'const' keyword is placed differently.
What this means is that the msymbol names and symbol names appear to
be completely different to GDB's completion tracker, and therefore to
readline when it offers the completions.
This commit builds on the previous commit which reworked the
completion_tracker class. It is now trivial to add a
remove_completion member function, this is then used along with
cp_canonicalize_string_no_typedefs to remove the msymbol aliases from
the completion tracker as we add the symbol names.
Now, for the above program GDB only presents a single completion for
'get_value', which is 'get_value(object_p)'.
It is still possible to reference the symbol using the msymbol name,
so a user can manually type out 'break get_value (object *)' if they
wish and will get the expected behaviour.
I did consider adding an option to make this alias exclusion optional,
in the end I didn't bother as I didn't think it would be very useful,
but I can easily add such an option if people think it would be
useful.
gdb/ChangeLog:
* completer.c (completion_tracker::remove_completion): Define new
function.
* completer.h (completion_tracker::remove_completion): Declare new
function.
* symtab.c (completion_list_add_symbol): Remove aliasing msymbols
when adding a C++ function symbol.

In this commit I rewrite how the completion tracker tracks the
completions, and builds its lowest common denominator (LCD) string.
The LCD string is now built lazily when required, and we only track
the completions in one place, the hash table, rather than maintaining
a separate vector of completions.
The motivation for these changes is that the next commit will add the
ability to remove completions from the list, removing a completion
will invalidate the LCD string, so we need to keep hold of enough
information to recompute the LCD string as needed.
Additionally, keeping the completions in a vector makes removing a
completion expensive, so better to only keep the completions in the
hash table.
This commit doesn't add any new functionality itself, and there should
be no user visible changes after this commit.
For testing, I ran the testsuite as usual, but I also ran some manual
completion tests under valgrind, and didn't get any reports about
leaked memory.
gdb/ChangeLog:
* completer.c (completion_tracker::completion_hash_entry): Define
new class.
(advance_to_filename_complete_word_point): Call
recompute_lowest_common_denominator.
(completion_tracker::completion_tracker): Call discard_completions
to setup the hash table.
(completion_tracker::discard_completions): Allow for being called
from the constructor, pass new equal function, and element deleter
when constructing the hash table. Initialise new class member
variables.
(completion_tracker::maybe_add_completion): Remove use of
m_entries_vec, and store more information into m_entries_hash.
(completion_tracker::recompute_lcd_visitor): New function, most
content taken from...
(completion_tracker::recompute_lowest_common_denominator):
...here, this now just visits each item in the hash calling the
above visitor.
(completion_tracker::build_completion_result): Remove use of
m_entries_vec, call recompute_lowest_common_denominator.
* completer.h (completion_tracker::have_completions): Remove use
of m_entries_vec.
(completion_tracker::completion_hash_entry): Declare new class.
(completion_tracker::recompute_lowest_common_denominator): Change
function signature.

gdb/ChangeLog:
Update copyright year range in all GDB files.

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.

This adds a completion helper routine that makes it possible for a
command that takes another command as argument, such as "frame apply
all COMMAND" as "thread apply all COMMAND", to complete on COMMAND,
and have the completion machinery recurse and complete COMMAND as if
you tried to complete "(gdb) COMMAND". I.e., we'll be able to
complete like this, for example:
(gdb) thread apply all -[TAB]
-c -ascending -q -s
(gdb) thread apply all -ascending frame apply all -[TAB]
-c -limit -past-entry -past-main -q -s
(gdb) thread apply all -ascending frame apply all -past-main print -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
(gdb) thread apply all -ascending frame apply all -past-main print glo[TAB]
global1 global2
Above, the completer function understands that "thread apply all" is a
command, and then parses "-ascending" successfully and understand that
the rest of the string is "thread apply all"'s operand. And then, the
process repeats for the "frame apply" command, and on and on.

As I was in the neighbourhood, I converted the other "compile"
subcommands to the new options framework too. Specifically, "compile
code" and "compile file".
The user-visible changes are:
- All abbreviations of "-raw" are accepted now, instead of just -r.
Obviously that means "-ra" is now accepted.
- Option completion now works.
- "compile file" did not have a completer yet, and now it knows to
complete on filenames.
- You couldn't use "compile file" with a file named "-something".
You can now, with "compile file -- -something".

Completion routines that use a custom word point, and that then
recurse into complete_line (e.g., if we make "thread apply" a custom
word point completer, and complete on the command passed as argument),
we stumble on this latent bug:
(gdb) thread apply all pri[TAB]
(gdb) thread apply all priprint
The problem is that there's a spot in complete_line_internal_1 that
rewinds the completion word but does not reflect that change in the
custom word point in the tracker. This patch fixes it.
gdb/ChangeLog:
2019-06-13 Pedro Alves <palves@redhat.com>
* completer.c (complete_line_internal_1): Rewind completion word
point.
(completion_tracker::advance_custom_word_point_by): Change
parameter type to int.
* completer.h (completion_tracker::advance_custom_word_point_by):
Likewise.

Extract completion logic from CLI complete_command() into a new

Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues
pointed out.

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.

gdb/ChangeLog:
Update copyright year range in all GDB files

I noticed this regression in the expression completer:
"(gdb) p std::[TAB]" => "(gdb) p std::std::"
obviously we should have not completed to "std::std::".
The problem is that in the earlier big completer rework, I missed
taking into account the fact that with expressions, the completion
word point is not always at the start of the symbol name (it is with
linespecs).
The fix is to run the common prefix / LCD string (what readline uses
to expand the input line) through make_completion_match_str too.
New testcase included, exercising both TAB completion and the complete
command.
gdb/ChangeLog:
2017-12-13 Pedro Alves <palves@redhat.com>
* completer.c (completion_tracker::maybe_add_completion): New
'text' and 'word' parameters. Use make_completion_match_str.
(completion_tracker::add_completion): New 'text' and 'word'
parameters. Pass down.
(completion_tracker::recompute_lowest_common_denominator): Change
parameter type to gdb::unique_xmalloc_ptr rval ref. Adjust.
* completer.h (completion_tracker::add_completion): New 'text' and
'word' parameters.
(completion_tracker::recompute_lowest_common_denominator): Change
parameter type to gdb::unique_xmalloc_ptr rval ref.
(completion_tracker::recompute_lowest_common_denominator): Change
parameter type to gdb::unique_xmalloc_ptr rval ref.
* symtab.c (completion_list_add_name): Pass down 'text' and 'word'
as well.
gdb/testsuite/ChangeLog:
2017-12-13 Pedro Alves <palves@redhat.com>
* gdb.cp/cpcompletion.exp: Load completion-support.exp.
("expression with namespace"): New set of tests.
* gdb.cp/pr9594.cc (Test_NS::foo, Test_NS::bar)
(Nested::Test_NS::qux): New.
* lib/completion-support.exp (test_gdb_complete_cmd_multiple): Add
defaults to 'start_quote_char' and 'end_quote_char' parameters.

We have several places doing essentially the same thing; factor them
out to a central place. Some of the places overallocate for no good
reason, or use strcat unnecessarily. The centralized version is more
precise and to the point.
(I considered making the gdb::unique_xmalloc_ptr overload version of
make_completer_match_str try to realloc (not xrealloc) probably
avoiding an allocation in most cases, but that'd be probably overdoing
it, and also, now that I'm writing this I thought I'd try to see how
could we ever get to filename_completer with "text != word", but I
couldn't figure it out. Running the testsuite with 'gdb_assert (text
== word);' never tripped on the assertion either. So post gdb 8.1,
I'll probably propose a patch to simplify filename_completer a bit,
and the gdb::unique_xmalloc_str overload can be removed then.)

Trying to set a breakpoint in a function with an ABI tag does not work
currently. E.g., debugging gdb itself, we see this with the
"string_printf" function:
(top-gdb) b string_print [TAB]
(top-gdb) b string_printf[abi:cxx11](char const*, ...) [RET]
No source file named string_printf[abi.
Make breakpoint pending on future shared library load? (y or [n])
Quoting doesn't help:
(top-gdb) b 'string_printf[abi:cxx11]'(char const*, ...)
malformed linespec error: unexpected string, "(char const*, ...)"
(top-gdb) b 'string_printf[abi:cxx11](char const*, ...)'
No source file named string_printf[abi.
Make breakpoint pending on future shared library load? (y or [n]) n
This patch fixes this, and takes it a bit further.
The actual symbol name as demangled by libiberty's demangler is really
string_printf[abi:cxx11](char const*, ...)
however, this patch makes it possible to set the breakpoint with
string_printf(char const*, ...)
too. I.e., ignoring the ABI tag.
And to match, it teaches the completer to complete the symbol name
without the ABI tag, i.e.,
"string_pri<TAB>" -> "string_printf(char const*, ...)"
If however, you really want to break on a symbol with the tag, then
you simply start writing the tag, and GDB will preserve it, like:
"string_printf[a<TAB>" -> "string_printf[abi:cxx11](char const*, ...)"
Grows the gdb.linespec/ tests like this:
-# of expected passes 8977
+# of expected passes 9176

A following patch will add support for wild matching for C++ symbols,
making completing on "b push_ba" on a C++ program complete to
std::vector<...>::push_back, std::string::push_back etc., like:
(gdb) b push_ba[TAB]
std::vector<...>::push_back(....)
std::string<...>::push_back(....)
Currently, we compute the "lowest common denominator" between all
completion candidates (what the input line is adjusted to) as the
common prefix of all matches. That's problematic with wild matching
as above, as then we'd end up with TAB changing the input line to
"b std::", losing the original input, like:
(gdb) b push_ba[TAB]
std::vector<...>::push_back(....)
std::string<...>::push_back(....)
(gdb) b std::
while obviously we'd want it to adjust itself to "b push_back(" instead:
(gdb) b push_ba[TAB]
std::vector<...>::push_back(....)
std::string<...>::push_back(....)
(gdb) b push_back(
This patch adds the core code necessary to support this, though
nothing really makes use of it yet in this patch.

Summary:
- This is preparation for supporting wild name matching on C++ too.
- This is also preparation for TAB-completion fixes.
- Makes symbol name matching (think strcmp_iw) be based on a per-language method.
- Merges completion and non-completion name comparison (think
language_ops::la_get_symbol_name_cmp generalized).
- Avoid re-hashing lookup name multiple times
- Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling),
both completion and non-completion.
- Fixes Ada latent bug with verbatim name matches in expressions
- Makes ada-lang.c use common|symtab.c completion code a bit more.
Ada's wild matching basically means that
"(gdb) break foo"
will find all methods named "foo" in all packages. Translating to
C++, it's roughly the same as saying that "break klass::method" sets
breakpoints on all "klass::method" methods of all classes, no matter
the namespace. A following patch will teach GDB about fullname vs
wild matching for C++ too. This patch is preparatory work to get
there.
Another idea here is to do symbol name matching based on the symbol
language's algorithm. I.e., avoid dependency on current language set.
This allows for example doing
(gdb) b foo::bar< int > (<tab>
and having gdb name match the C++ symbols correctly even if the
current language is C or Assembly (or Rust, or Ada, or ...), which can
easily happen if you step into an Assembly/C runtime library frame.
By encapsulating all the information related to a lookup name in a
class, we can also cache hash computation for a given language in the
lookup name object, to avoid recomputing it over and over.
Similarly, because we don't really know upfront which languages the
lookup name will be matched against, for each language we store the
lookup name transformed into a search name. E.g., for C++, that means
demangling the name. But for Ada, it means encoding the name. This
actually forces us to centralize all the different lookup name
encoding in a central place, resulting in clearer code, IMO. See
e.g., the new ada_lookup_name_info class.
The lookup name -> symbol search name computation is also done only
once per language.
The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are
generalized to work with both completion, and normal symbol look up.
At some point early on, I had separate completion vs non-completion
language vector entry points, but a single method ends up being better
IMO for simplifying things -- the more we merge the completion /
non-completion name lookup code paths, the less changes for bugs
causing completion vs normal lookup finding different symbols.
The ada-lex.l change is necessary because when doing
(gdb) p <UpperCase>
then the name that is passed to write_ write_var_or_type ->
ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase",
and we end up doing a wild match against "UpperCase" lowercased by
ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever
match "UpperCase", and the symbol lookup fails.
This wouldn't cause any regression in the testsuite, but I added a new
test that would pass before the patch and fail after, if it weren't
for that fix.
This is latent bug that happens to go unnoticed because that
particular path was inconsistent with the rest of Ada symbol lookup by
not lowercasing the lookup name.
Ada's symbol_completion_add is deleted, replaced by using common
code's completion_list_add_name. To make the latter work for Ada, we
needed to add a new output parameter, because Ada wants to return back
a custom completion candidates that are not the symbol name.
With this patch, minimal symbol demangled name hashing is made
consistent with regular symbol hashing. I.e., it now goes via the
language vector's search_name_hash method too, as I had suggested in a
previous patch.
dw2_expand_symtabs_matching / .gdb_index symbol names were a
challenge. The problem is that we have no way to telling what is the
language of each symbol name found in the index, until we expand the
corresponding full symbol, which is off course what we're trying to
avoid. Language information is simply not considered in the index
format... Since the symbol name hashing and comparison routines are
per-language, we now have a problem. The patch sorts this out by
matching each name against all languages. This is inneficient, and
indeed slows down completion several times. E.g., with:
$ cat script.cmd
set pagination off
set $count = 0
while $count < 400
complete b string_prin
printf "count = %d\n", $count
set $count = $count + 1
end
$ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd"
I get, before patch (-O2, x86-64):

user 0m1.737s
sys 0m0.040s
While after patch (-O2, x86-64):

user 0m9.482s
sys 0m0.034s
However, the following patch will optimize this, and will actually
make this use case faster compared to the "before patch" above:

user 0m1.285s
sys 0m0.039s

Continuing the theme of the explicit locations patch, this patch gets
rid of the need for quoting function names in linespec TAB completion.
To recap, when you have overloads in your program, and you want to set
a breakpoint in one of them:
void function(int); // set breakpoint here.
void function(long);
(gdb) b function(i[TAB]
<all the symbols in the program that start with "i" are uselessly shown...>
This patch gets rid of the need for quoting by switching the linespec
completer to use the custom completion word point mechanism added in
the previous explicit location patch (extending it as needed), to
correctly determine the right completion word point. In the case
above, we want the completer to figure out that it's completing a
function name that starts with "function(i", and it now does.
We also want the completer to know when it's potentially completing a
source file name, for:
(gdb) break source.[TAB] -> source.c:
(gdb) break source.c: # Type line number or function name now
And we want it to know to complete label names, which it doesn't today:
(gdb) break function:lab[TAB]
etc., etc.
So what we want is for completion to grok the input string as closely
to how the linespec parser groks it.
With that in mind, the solution suggests itself - make the linespec
completer use the same parsing code as normal linespec parsing.
That's what the patch does. The old completer is replaced by one that
reuses the actual linespec parser as much as possible. This (ideally)
eliminate differences between what completion understands and actually
setting breakpoints understands by design.
The completer now offers sensible completion candidates depending on
which component of the linespec is being completed, source filename,
function, line number, expression, and (a new addition), labels. For
example, when completing the function part, we now show the full name
of the method as completion candidates, instead of showing whatever
comes after what readline considered the word break character:
(gdb) break klass::method[TAB]
klass:method1(int)
klass:method2()
If input is past the function, then we now offer keyword condidates:
(gdb) b function(int) [TAB]
if task thread
If input is past a keyword, we offer expression completion, which is
different from linespec completion:
(gdb) b main if 1 + glo[TAB]
global
(e.g., completes on types, struct data fields, etc.)
As mentioned, this teaches the linespec completer about completing
label symbols too:
(gdb) b source.c:function:lab[TAB]
A nice convenience is that when completion uniquely matches a source
name, gdb adds the ":" automatically for you:
(gdb) b filenam[TAB]
(gdb) b filename.c: # ':' auto-added, cursor right after it.
It's the little details. :-)
I worked on this patch in parallel with writing the (big) testcase
added closer to the end of the series, which exercises many many
tricky cases around quoting and whitespace insertion placement. In
general, I think it now all Just Works.

One of the most annoying (to me) things about GDB's completion is when
you have overloads in your program, and you want to set a breakpoint
in one of them:
void function(int); // set breakpoint here.
void function(long);
(gdb) b -f func[TAB]
(gdb) b -f function( # ok, gdb completed as much as possible.
(gdb) b -f function([TAB] # show me the overloads, please.
<_all_ symbols in the program are shown...>
E.g., when debugging GDB, that'd be:
(gdb) b -f function([TAB]
(anonymous namespace)::get_global()::global pt_insn_get_offset@plt scm_new_port_table_entry
asprintf pt_pkt_alloc_decoder scm_new_port_table_entry@plt
asprintf@plt pt_pkt_alloc_decoder@plt scm_out_of_range
bt_ctf_get_char_array pt_pkt_sync_forward scm_out_of_range@plt
bt_ctf_get_char_array@plt pt_pkt_sync_forward@plt scm_putc
bt_ctf_get_uint64 pwrite scm_putc@plt
bt_ctf_get_uint64@plt pwrite@plt scm_reverse_x
bt_ctf_iter_read_event PyErr_Restore scm_reverse_x@plt
bt_ctf_iter_read_event@plt PyErr_Restore@plt scm_set_port_filename_x
<snip...>
Now that's a load of completely useless completions.
The reason GDB offers those is that the completer relies on readline
figuring out the completion word point in the input line based on the
language's word break characters, which include "(". So readline
tells the completer to complete on "", the string that is after '('.
Likewise, if you type "function(i[TAB]" to try to complete to "int",
you're out of luck. GDB shows you all the symbols in the program that
start with "i"... This makes sense for the expression completer, as
what you'd want to type is e.g., a global variable, say:
(gdb) print function(i[TAB]
but, it makes no sense when specifying a function name for a
breakpoint location.
To get around that limitation, users need to quote the function name,
like:
(gdb) b -f 'function([TAB]
function(int) function(long)
(gdb) b 'function(i[TAB]
(gdb) b 'function(int)' # now completes correctly!
Note that the quoting is only necessary for completion. Creating the
breakpoint does not require the quoting:
(gdb) b -f function(int) [RET]
Breakpoint 1 at ....
This patch removes this limitation.
(
Actually, it's a necessary patch, though not sufficient. That'll
start working correctly by the end of the series. With this patch, if try it,
you'll see:
(gdb) b -f function(i[TAB]
(gdb) b -f function
i.e., gdb strips everything after the "(". That's caused by some code
in symtab.c that'll be eliminated further down the series. These
patches are all unfortunately interrelated, which is also the reason
new tests only appear much later in the series.
But let's ignore that reality for the remainder of the description.
)
So... this patch gets rid of the need for quoting.
It does that by adding a way for a completer to control the exact
completion word point that readline should start the completion
request for, instead of letting readline try to figure it out using
the current language's word break chars array, and often failing.
In the case above, we want the completer to figure out that it's
completing a function name that starts with "function(i". It now
does.
It took me a while to figure out a way to ask readline to "use this
exact word point", and for a while I feared that it'd be impossible
with current readline (and having to rely on master readline for core
functionality is something I'd like to avoid very much). Eventually,
after several different attempts, I came up with what is described in
the comment above gdb_custom_word_point_brkchars in the patch.
With this patch, the handle_brkchars phase of the explicit location
completer advances the expected word point as it parses the input line
left to right, until it figures out exactly what we're completing,
instead of expecting readline to break the string using the word break
characters, and then having the completer heuristically fix up a bad
decision by parsing the input string backwards. This allows correctly
knowning that we're completing a symbol name after -function, complete
functions without quoting, etc.
Later, we'll make use of this same mechanims to implement a proper
linespec completer that avoids need for quoting too.

The linespec/locations/completer testcase added later in the series
tests every completion with both TAB completion and the "complete"
command. This exposed problems in the "complete" command, around
determining the completion word point.
First, the complete command has a too-simple approximation of what
readline's TAB-completion code does to find the completion word point.
Unfortunately, readline doesn't expose the functionality it uses
internally, so to fix this this patch copies over the relevant code,
and adjusts it a bit to better fit the use cases we need it for.
(Specifically, our version avoids relying on the
rl_word_break_characters, etc. globals, and instead takes those as
arguments.)
A following patch will want to use this function for TAB-completion
too, but the "complete" command was a good excuse to split this to a
separate patch.
Then, notice how the complete_command does not call into the completer
for the command being completed to determine the right set of word
break characters. It always uses the default set. That is fixed by
having the "complete" command call into complete_line_internal for a
full handle_brkchars phase, just TAB-completion.

This patch reworks the whole completion machinery, and prepares it
for later enhancements.
Adds a new "completion_tracker" class that is meant to hold everything
about the state of the current completion operation.
This class now has the responsibility of tracking the list of
completion matches, and checking whether the max completions limit has
been reached. You can look at this as this patch starting out by
C++fying the existing "completion_tracker" in symtab.c (it's just an
htab_t typedef currently), moving it to completer.h/c, and then making
it a class/generalizing/enhancing it.
Unlike with the current tracking, completion_tracker now checks
whether the limit has been reached on each completion match list
insertion. This both simplifies the max-completions handling code
(maybe_add_completion_enum is gone, for example), and is a
prerequisite for follow up patches.
The current completion_tracker is only used for symbol completions,
and the symbol code gets at the current instance via globals. This
patch cleans that up by adding a completion_tracker reference to the
signature of the completion functions, and passing the tracker around
everywhere necessary.
Then, the patch changes how the completion match list is handed over
to readline. Currently, we're using the rl_completion_entry_function
readline entry point, and the patch switches to
rl_attempted_completion_function. A following patch will want to let
GDB itself decide the common completion prefix between all matches
(what readline calls the "lowest common denominator"), instead of
having readline compute it, and that's not possible with the
rl_completion_entry_function entry point. Also,
rl_attempted_completion_function lets GDB hand over the match list to
readline as an array in one go instead of passing down matches one by
one, so from that angle it's a nicer entry point anyway.
Lastly, the patch catches exceptions around the readline entry points,
because we can't let C++ exceptions cross readline. We handle that in
the readline input entry point, but the completion entry point isn't
guarded, so GDB can abort if completion throws. E.g., in current
master:
(gdb) b -function "fun<tab>
terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
Aborted (core dumped)
This patch fixes that. This will be exercised in the new tests added
later on in the series.

- Centralizes all the "completer method" to "handle_brkchars method"
mapping in a single function.

-Wwrite-strings flags several cases of missing casts around
initializations like:
static char *gdb_completer_command_word_break_characters =
" \t\n!@#$%^&*()+=|~`}{[]\"';:?/>.<,";
Obviously these could/should be const. However, while at it, there's
no need for these variables to be pointers instead of arrays. They
are never changed to point to anything else.
Unfortunately, readline's rl_completer_word_break_characters is
"char *", not "const char *". So we always need a cast somewhere. The
approach taken here is to add a new
set_rl_completer_word_break_characters function that becomes the only
place that writes to rl_completer_word_break_characters, and thus the
single place that needs the cast.

We previously specified a few known register groups for the 'tui reg'
command. Other register groups could be accessed, but only by using the
'tui reg next' command and cycling through all the groups.
This commit removes the hard coded sub-commands of 'tui reg' and instead
adds dynamic completion of sub-commands based on the architecturally
defined register groups, giving immediate access to all available
register groups.
There is still the 'next' and 'prev' commands for cycling through the
register groups if that's wanted.
The new code maintains the ability to only enter partial names for
register groups, which is something we got for free when using the
standard sub-command mechanism.
The register (and register group) completer has been changed to use
get_current_arch rather than using the architecture of the currently
selected frame. When the target is running, this is equivalent,
however, when the target is not running, using get_current_arch will
provide results from the default architecture.

This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be
thrown whenever the completer has generated too many candidates to
be useful. A new user-settable variable, "max_completions", is added
to control this behaviour. A top-level completion limit is added to
complete_line_internal, as the final check to ensure the user never
sees too many completions. An additional limit is added to
default_make_symbol_completion_list_break_on, to halt time-consuming
symbol table expansions.

Provide a new completion function for the argument of "info
registers", "info all-registers", and the "lr" command in dbx mode.
Without this patch the default symbol completer is used, which is more
confusing than helpful.
Also add a test for this new feature to "completion.exp": Determine
the target's available set of registers/reggroups and compare this to
the completion of "info registers ". For determining the available
registers involve the new "maint print user-registers" command.

completer class
This PR came from a Red Hat bug that was filed recently. I checked and
it still exists on HEAD, so here's a proposed fix. Although this is
marked as a Python backend bug, this is really about the completion
mechanism used by GDB. Since this code reminds me of my first attempt
to make a good noodle, it took me quite some time to fix it in a
non-intrusive way.
The problem is triggered when one registers a completion method inside a
class in a Python script, rather than registering the command using a
completer class directly. For example, consider the following script:
class MyFirstCommand(gdb.Command):
def __init__(self):
gdb.Command.__init__(self,'myfirstcommand',gdb.COMMAND_USER,gdb.COMPLETE_FILENAME)
def invoke(self,argument,from_tty):
raise gdb.GdbError('not implemented')
class MySecondCommand(gdb.Command):
def __init__(self):
gdb.Command.__init__(self,'mysecondcommand',gdb.COMMAND_USER)
def invoke(self,argument,from_tty):
raise gdb.GdbError('not implemented')
def complete(self,text,word):
return gdb.COMPLETE_FILENAME
MyFirstCommand ()
MySecondCommand ()
When one loads this into GDB and tries to complete filenames for both
myfirstcommand and mysecondcommand, she gets:
(gdb) myfirstcommand /hom<TAB>
(gdb) myfirstcommand /home/
^
...
(gdb) mysecondcommand /hom<TAB>
(gdb) mysecondcommand /home
^
(The "^" marks the final position of the cursor after the TAB).
So we see that myfirstcommand honors the COMPLETE_FILENAME class (as
specified in the command creation), but mysecondcommand does not. After
some investigation, I found that the problem lies with the set of word
break characters that is used for each case. The set should be the same
for both commands, but it is not.
During the process of deciding which type of completion should be used,
the code in gdb/completer.c:complete_line_internal analyses the command
that requested the completion and tries to determine the type of
completion wanted by checking which completion function will be called
(e.g., filename_completer for filenames, location_completer for
locations, etc.).
This all works fine for myfirstcommand, because immediately after the
command registration the Python backend already sets its completion
function to filename_completer (which then causes the
complete_line_internal function to choose the right set of word break
chars). However, for mysecondcommand, this decision is postponed to
when the completer function is evaluated, and the Python backend uses an
internal completer (called cmdpy_completer). complete_line_internal
doesn't know about this internal completer, and can't choose the right
set of word break chars in time, which then leads to a bad decision when
completing the "/hom" word.
So, after a few attempts, I decided to create another callback in
"struct cmd_list_element" that will be responsible for handling the case
when there is an unknown completer function for complete_line_internal
to work with. So far, only the Python backend uses this callback, and
only when the user provides a completer method instead of registering
the command directly with a completer class. I think this is the best
option because it not very intrusive (all the other commands will still
work normally), but especially because the whole completion code is so
messy that it would be hard to fix this without having to redesign
things.
I have regtested this on Fedora 18 x86_64, without regressions. I also
included a testcase.

This is sort of a continuation of Keith's parse_exp_1 constification
patch. It started out by undoing these bits:
@@ -754,9 +754,12 @@ validate_actionline (char **line, struct
tmp_p = p;
for (loc = t->base.loc; loc; loc = loc->next)
{
- p = tmp_p;
- exp = parse_exp_1 (&p, loc->address,
+ const char *q;
+
+ q = tmp_p;
+ exp = parse_exp_1 (&q, loc->address,
block_for_pc (loc->address), 1);
+ p = (char *) q;
and progressively making more things const upwards, fixing fallout,
rinse repeat, until GDB built again (--enable-targets=all).
That ended up constifying lookup_cmd/add_cmd and (lots of) friends,
and the completers.
I didn't try to constify the command hooks themselves, because I know
upfront there are commands that write to the command string argument,
and I think I managed to stop at a nice non-hacky split point already.
I think the only non-really-super-obvious changes are
tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions.
The rest is just mostly about 'char *' => 'const char *', 'char **'=>
'const char **', and the occasional (e.g., deprecated_cmd_warning)
case of 'char **'=> 'const char *', where/when I noticed that nothing
actually cares about the pointer to pointer output.
Tested on x86_64 Fedora 17, native and gdbserver.

The command line completion has spoiled me. Thus the lack of completion with
the "handle" command annoys me. Patch!
This does a few things:
- adds a VEC_merge helper
- adds a generic signal completer
- adds a completion handler for the "handle" command
- sets the completion handler for the "signal" command
