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.

When running tests in parallel, each test puts its generated files in a
different directory, under "outputs". I think it would be nice if it
was always the case, as it would isolate the test cases a bit more. An
artifact created by a test wouldn't get overwritten by another test.
Also, it makes it easier to clean up. A lot of executables are left all
over the place because their names do not appear in gdb.*/Makefile. If
everything is in "outputs", then we just have to delete that directory
(which we already do).
At the same time it makes the gdb.foo directories and their Makefiles
useless in the build directory, since they are pretty much only used for
cleaning.
What do you think?

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

One of the build slaves shows this error running explicit.exp:

Remote failure reply: E.In-process agent library not loaded in process.
Fast and static tracepoints unavailable.
(gdb) FAIL: gdb.linespec/explicit.exp: strace -m gdbfoobarbaz
There are two big problems with this test:
1) The expected output is actually not what the test is meant to test for.
2) This test should really only run where it is supported.
This is most easily fixed by moving the test to gdb.trace/strace.exp.

This patch exposes explicit locations to the CLI user. This enables
users to "explicitly" specify attributes of the breakpoint location
to avoid any ambiguity that might otherwise exist with linespecs.
The general syntax of explicit locations is:
-source SOURCE_FILENAME -line {+-}LINE -function FUNCTION_NAME
-label LABEL_NAME
Option names may be abbreviated, e.g., "-s SOURCE_FILENAME -li 3" and users
may use the completer with either options or values.

break-asm-file.exp has some manually written dwarf to create some line
number entries like this,
[0x0000013d] Extended opcode 2: set Address to 0x40053f
[0x00000144] Advance Line by 4 to 7
[0x00000146] Copy
[0x00000147] Extended opcode 2: set Address to 0x400541
[0x0000014e] Advance Line by 1 to 8
[0x00000150] Copy
[0x00000151] Extended opcode 2: set Address to 0x400547
[0x00000158] Extended opcode 1: End of Sequence
0x40053f is the start address of function func, and is mapped to line
7. 0x400541 is within function func, and is mapped to line 8.
(gdb) disassemble /r 0x40053f,+8
Dump of assembler code from 0x40053f to 0x400547:
0x000000000040053f <func+0>: 00 00 add %al,(%rax)
0x0000000000400541 <func+2>: 00 00 add %al,(%rax)
0x0000000000400543 <func+4>: 00 00 add %al,(%rax)
0x0000000000400545 <func+6>: 00 00 add %al,(%rax)
in the following test,
(gdb) break a/break-asm-file0.s:func
Breakpoint 1 at 0x40053f: file a/break-asm-file0.s, line 7.
As we can see, breakpoint is set at the start address of function func
on x86, which means no prologue is skipped. On other targets, such as
arm and aarch64, breakpoint is set at the address *after* the start
address, which is mapped to line 8. Then test fails.
In fact, it is lucky this test doesn't fail on x86 and x86_64, whose
gdbarch method skip_prologue doesn't reply on skip_prologue_using_sal
if producer isn't clang.
if (find_pc_partial_function (start_pc, NULL, &func_addr, NULL))
{
CORE_ADDR post_prologue_pc
= skip_prologue_using_sal (gdbarch, func_addr);
struct compunit_symtab *cust = find_pc_compunit_symtab (func_addr);
/* Clang always emits a line note before the prologue and another
one after. We trust clang to emit usable line notes. */
if (post_prologue_pc
&& (cust != NULL
&& COMPUNIT_PRODUCER (cust) != NULL
&& startswith (COMPUNIT_PRODUCER (cust), "clang ")))
return max (start_pc, post_prologue_pc);
}
so it doesn't return and go further to prologue analyser. Since ".int 0"
isn't an instruction of prologue, nothing is skipped, starting address
is used, and test passes.
however, on targets which don't have such producer checking, the first
line number entry is skipped, and skip_prologue_using_sal returns sal
represents the second line number entry.
The idea of this patch is to force GDB stop at somewhere which is stilled
mapped to line 7 after skipping prologue. I choose to add a new line
number entry for the following instruction but mapped to the same line (7),
because I see the comments in dwarf2read.c,
... fact that two consecutive
line number entries for the same line is a heuristic used by gcc
to denote the end of the prologue.
then the line table becomes:
[0x000000d4] Extended opcode 2: set Address to 0x400529
[0x000000db] Advance Line by 4 to 7
[0x000000dd] Copy
[0x000000de] Extended opcode 2: set Address to 0x40052a
[0x000000e5] Advance Line by 0 to 7
[0x000000e7] Copy
[0x000000e8] Extended opcode 2: set Address to 0x40052b
[0x000000ef] Advance Line by 1 to 8
[0x000000f1] Copy
[0x000000f2] Extended opcode 2: set Address to 0x40052c

This patch changes the heuristic the linespec lexer uses to
detect a keyword in the input stream.
Currently, the heuristic is: a word is a keyword if it
1) points to a string that is a keyword
2) is followed by a non-identifier character
This is strictly more correct than using whitespace. For example,
it allows constructs such as "break foo if(i == 1)". However,
find_condition_and_thread in breakpoint.c does not support this expanded
usage. It requires whitespace to follow the keyword.
The proposed new heuristic is: a word is a keyword if it
1) points to a string that is a keyword
2) is followed by whitespace
3) is not followed by another keyword string followed by whitespace
This additional complexity allows constructs such as
"break thread thread 3" and "break thread 3". In the former case,
the actual location is a symbol named "thread" to be set on thread #3.
In the later case, the location is NULL, i.e., the default location,
to be set on thread #3.
In order to pass all the new tests added here, I've also had to add a
new feature to parse_breakpoint_sals, which expands recognition of the
default location to keywords other than "if", which is the only keyword
currently permitted with the default (NULL) location, but there is no
reason to exclude other keywords.
Consequently, it will be possible to use "break thread 1" or
"break task 1".
In addition to all of this, it is now possible to remove the keyword_ok
state from the linespec parser.

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.

This patch fixes a problem when trying to insert a breakpoint on
a specific symbol defined in a specific file, eg:
break foo.c:func
This currently works for files in C/C++/Ada, etc, but doesn't always
work for Asm files. Analysis of the problem showed that this related
to a limitation in gas, which does not generate debug info for functions/
symbols. Thus, we have a symtab for the file ("info sources" shows
the file), but it contains no symbols.
When find_linespec_symbols is called in linespec_parse_basic, it calls
find_function_symbols, which uses add_matching_symbols_to_info to
collect all matching symbols.
That function does [pardon any mangled formatting]:
for (ix = 0; VEC_iterate (symtab_ptr, info->file_symtabs, ix, elt); ++ix)
{
if (elt == NULL)
{
iterate_over_all_matching_symtabs (info->state, name, VAR_DOMAIN,
collect_symbols, info,
pspace, 1);
search_minsyms_for_name (info, name, pspace);
}
else if (pspace == NULL || pspace == SYMTAB_PSPACE (elt))
{
/* Program spaces that are executing startup should have
been filtered out earlier. */
gdb_assert (!SYMTAB_PSPACE (elt)->executing_startup);
set_current_program_space (SYMTAB_PSPACE (elt));
iterate_over_file_blocks (elt, name, VAR_DOMAIN,
collect_symbols, info);
}
}
This iterates over the symtabs. In the failing use case, ELT is
non-NULL (points to the symtab for the .s file), so it calls
iterate_over_file_blocks. Herein is where the problem exists: it is
assumed that if NAME exists, it must exist in the given symtab -- a
reasonable assumption for "normal" (non-asm) cases. It never searches
minimal symbols (or in the global default symtab).
This patch fixes the problem by doing so. It is important to note that
iterating over minsyms is fairly expensive, so this patch only adds
that extra search if the language is language_asm and
iterate_over_file_blocks returns no symbols.

Several GDB tests change directory before compiling the test program
in order to test source file names that include directories. This
doesn't work on a remote host because default_target_compile in
DejaGnu's target.exp copies each source file with
"[remote_download host $x]" which uses "[file tail $file] to strip
off the directory of each file. If the source directory is remote
mounted on the host, this also leaves copied files in the source
directory.
A similar skip is already used in gdb.test/fullname.exp:
# We rely on being able to copy things around.
if { [is_remote host] } {
untested "setting breakpoints by full path"
return -1
}
This patch causes three GDB tests that use "cd" to be skipped for a
remote host. For gdb.base/fullpath-expand.exp this eliminates two
failures and prevents the test from leaving files fullpath-expand.c
and fullpath-expand-func.c in gdb/testsuite. For
gdb.base/realname-expand.exp it eliminates two failures. For
gdb.linespec/macro-relative.exp it prevents file macro-relative.c
from being left in gdb/testsuite/gdb.linespec/base/two.
