4 breakpoint keep y 0x000000000040061f in end at thread-specific-bp.c:29
breakpoint already hit 1 time
Note that the thread-specific breakpoint 3 stayed around, even though
thread 2 is gone.
There's no way that breakpoint can trigger again (*), so the PR argues
that the breakpoint should just be removed, like local watchpoints.
I'm ambivalent on this -- it could be reasonable to disable the
breakpoint (kind of like breakpoint in shared library code when the
DSO is unloaded), so the user could still use it as visual template
for creating other breakpoints (copy/paste command lists, etc.), or we
could have a way to change to which thread a breakpoint applies. But,
several people pushed this direction, and I don't plan on arguing...
(*) - actually, there is ... thread numbers are reset on "run", so
the user could do "break foo thread 2", "run", and expect the
breakpoint to hit again on the second thread. But given gdb's thread
numbering can't really be stable, that'd only work sufficiently well
for thread 1, so we'd better call it unsupported.
So with the patch, whenever a thread is deleted from GDB's list, GDB
goes through the thread-specific breakpoints and deletes corresponding
breakpoints. Since this is user-visible, GDB prints out:
Thread-specific breakpoint 3 deleted - thread 2 is gone.
And of course, we end up with:

The issue is that print_stack_frame always sets the current sal to the
frame's sal. print_frame_info (which print_stack_frame calls to do
most of the work) also sets the last displayed sal, but only if
print_what isn't LOCATION. Now the call in question, from within
thread.c:print_thread_info, does pass in LOCATION as print_what, but
print_stack_frame doesn't have the same check print_frame_info has.
We could consider adding it, but setting these globals depending on
print_what isn't very clean, IMO. What we have is two logically
distinct operations mixed in the same function(s):
#1 - print frame, in the format specified by {print_what,
print_level and print_args}.
#2 - We're displaying a frame to the user, and I want the default
sal to point here, because the program stopped here, or the user
did some context-changing command (up, down, etc.).
So I added a new parameter to print_stack_frame & friends for point
#2, and went through all calls in the tree adjusting as necessary.
Tested on x86_64 Fedora 17.

This patch adds a new convenience function called $_isvoid, whose
only purpose is to check whether an expression is void or not.
This became necessary because the new convenience variable
$_exitsignal (not yet approved) has a mutual exclusive behavior
with $_exitcode, i.e., when one is "defined" (i.e., non-void),
the other is cleared (i.e., becomes void). Doug wanted a way to
identify which variable to use, and checking for voidness is the
obvious solution.
It is worth mentioning that my first attempt, after a conversation with
Doug, was to actually implement a new $_isdefined() convenience
function. I would do that (for convenience variables) by calling
lookup_only_internalvar. However, I found a few problems:
- Whenever I called $_isdefined ($variable), $variable became defined
(with a void value), and $_isdefined always returned true.
- Then, I tried to implement $_isdefined ("variable"), and do the "$" +
"variable" inside GDB, thus making it impossible for GDB to create the
convenience variable. However, it was hard to extract the string
without having to mess with values and their idiossincrasies.
Therefore, I decided to abandon this attempt (specially because I
didn't want to spend too much time struggling with it).
Anyway, after talking to Doug again we decided that it would be easier
to implement $_isvoid, and this will probably help in cases like
<http://stackoverflow.com/questions/3744554/testing-if-a-gdb-convenience-variable-is-defined>.
I wrote a NEWS entry for it, and some new lines on the documentation.

'skip_unavailable' is true.

locals have been collected.

This finishes making gdb.dwarf2 parallel-safe.
To do this, this patch introduces a new gdb_remote_download proc, that
works somewhat differently in the one specific case where it matters:
for a copy to "host", if no destination was given, and the host is not
actually remote, then standard_output_file is used. In parallel mode
this guarantees that the resulting file will end up in a parallel-safe
location.

This introduces parallel mode for the test suite.
It doesn't fully work yet in the sense that if you do a fully parallel
run, you will encounter some file-name clashes, but this has to start
somewhere, and it seemed best to add some infrastructure now, so that
you can follow along and test subsequent patches if you care to.
This patch has two parts.
First, it checks for the GDB_PARALLEL variable. If this is set (say,
on the runtest command line), then the test suite assumes "parallel
mode". In this mode, files are put into a subdirectory named after
the test. That is, for DIR/TEST.exp, the outputs are put into
./outputs/DIR/TEST/.
This first part has various follow-on changes coming in subsequent
patches. This is why the code in this patch also makes "temp" and
"cache" directories.
Second, this adds an "inotify" mode. If you have the inotifywait
command (part of inotify-tools), you can set the GDB_INOTIFY variable.
This will tell the test suite to watch for changes outside of the
allowed output directories.
This mode is useful for debugging the test suite, as it issues a
report whenever a possibly parallel-unsafe file open is done.

gdb/ChangeLog
* common/format.c (parse_format_string): Don't allow '#' flag for
pointer arguments in format string.
gdb/testsuite/ChangeLog
* gdb.base/printcmds.exp (test_printf): Add test for printf of
pointer with various flags.
In the fully parallel mode, each .exp file can be run in parallel (at
least conceptually -- the actual split may not be so severe). This
means that procs that compute a result and cache it are not going to
function very well. The test they run will be invoked over and over.
This patch introduces a generic caching mechanism and changes various
result-caching procs to use it. This is a cleanup to introduce the
basic change; the results aren't written to disk yet.
A caching proc is defined using gdb_caching_proc, which works like
"proc", except that it caches the result of the body.
* lib/cache.exp: New file.
* lib/cell.exp (skip_cell_tests): Use gdb_caching_proc.
* lib/gdb.exp: Load cache.exp.
(support_complex_tests, is_ilp32_target, is_lp64_target)
(is_amd64_regs_target, skip_altivec_tests, skip_vsx_tests)
(gdb_skip_xml_test): Use gdb_caching_proc.
* lib/opencl.exp (skip_opencl_tests): Use gdb_caching_proc.
This adds a new helper proc, standard_temp_file. This proc takes a
file name and returns a possibly-qualified form. This lets us make
parallel runs use a directory other than ".", which helps the inotify
mode.
This initial patch introduces the proc and changes a few spots to use
it.
* lib/gdb.exp (standard_temp_file): New proc.
(support_complex_tests, is_ilp32_target, is_lp64_target)
(is_amd64_regs_target, skip_altivec_tests, skip_vsx_tests): Use
standard_temp_file.
