Subject: [patch] testsuite: Test readline-6.2 "ask" regression
Hi,
this problem does not affect default FSF GDB build as it is using bundled
readline-5.1. But with system readline-6.2 and build using:
--with-system-readline use installed readline library
GDB will no longer ask about displaying too many symbols and dumps them all
immediately.
PASS:
$ gdb gdb
(gdb) p <tab><tab>
Display all 21482 possibilities? (y or n)_
FAIL:
$ gdb gdb
(gdb) p <tab><tab>
Display all 22129 possibilities? (y or n)
../../bfd/aout-target.h cs_to_section
../../bfd/aout32.c ctime
<screens and screens of dumps without any question>
This regression will soon start affecting distros:
FSF GDB HEAD - PASS - using bundled readline-5.1
fedora-15 - FAIL - using system readline-6.2
fedora-14 - PASS - using system readline-6.1
debian-6.0 - PASS - using system readline-6.1
kubuntu-10.10 - PASS - using system readline-6.1
I have asked about it on readline ml:
Re: [Bug-readline] callback mode pager disable status
https://lists.gnu.org/archive/html/bug-readline/2011-04/msg00012.html
The suggested workaround (in fact the readline-5.1 code state) going to patch
into the proposed FSF GDB bundled readline-6.2. Distros then can stop using
--with-system-readline to still feature recent and system matching readline
until readline-7.0 gets released.
This regression has been so far caught only with system debug infos installed:
-PASS: gdb.base/completion.exp: complete (2) 'p no_var_named_this-'
-PASS: gdb.base/completion.exp: complete 'p values[0].a'
-PASS: gdb.base/completion.exp: complete 'p values[0] . a'
-PASS: gdb.base/completion.exp: complete 'p &values[0] -> a'
-PASS: gdb.base/completion.exp: copmletion of field in anonymous union

+FAIL: gdb.base/completion.exp: (timeout) complete 'p &values[0] -> a' 2

I will check it in with no comments.

Subject: [gdb FYI-patch] callback-mode readline-6.0 regression
Hi Chet,
FSF GDB currently ships bundled with readline-5.2 which works fine.
But using --with-system-readline and readline-6.0-patchlevel4 has
a regression:
readline-5.2: Run `gdb -nx -q' and type CTRL-C:
(gdb) Quit
(gdb) _
readline-6.0: Run `gdb -nx -q' and type CTRL-C:
(gdb) _
= nothing happens (it gets buffered and executed later)
(It does also FAIL on gdb.gdb/selftest.exp.)
It is because GDB waits in its own poll() mainloop and readline uses via
rl_callback_handler_install and rl_callback_handler_remove. This way the
readline internal variable _rl_interrupt_immediately remains 0 and CTRL-C gets
only stored to _rl_caught_signal but not executed.
Seen in rl_signal_handler even if _rl_interrupt_immediately is set and
_rl_handle_signal is called then the signal is still stored to
_rl_caught_signal. In the _rl_interrupt_immediately case it should not be
stored when it was already processed.
rl_signal_handler does `_rl_interrupt_immediately = 0;' - while I am not aware
of its meaning it breaks the nest-counting of other routines which do
`_rl_interrupt_immediately++;' and `_rl_interrupt_immediately--;' possibly
creating problematic `_rl_interrupt_immediately == -1'.
`_rl_interrupt_immediately' is an internal variable, how it could be accessed
by a readline application? (OK, maybe it should not be used.)
Attaching a current GDB-side patch but it must access readline internal
variable _rl_caught_signal and it is generally just a workaround. Could you
please include support for signals in this asynchronous mode in readline-6.1?
I find it would be enough to make RL_CHECK_SIGNALS public?
GDB: No regressions on {x86_64,x86_64-m32,i686}-fedora12-linux-gnu.
But this is not a patch intended to be accepted.
Thanks,
Jan
