Sync readline/ to version 7.0 alpha
This patch syncs our upstream copy of readline from version 6.2 to the
latest version, 7.0 alpha (released July 10 2015).
I essentially copied what was done the last time readline was synced,
when Jan updated to readline 6.2 in 2011:
http://sourceware.org/ml/gdb-patches/2011-05/msg00003.html
Procedure:
1. I extracted the readline-7.0-alpha tarball on top of readline/.
2. I deleted all the new files under doc/ that were deliberately omitted
before.
3. I regenerated readline/configure and readline/examples/rlfe/configure
using autoconf 2.64. No other configure files need regenerating.
4. I updated the function gdb_printable_part in completer.c with a
trivial change made to the readline function it is based off of,
printable_part in readline/complete.c. There is more work to be done in
completer.c to sync it with readline/complete.c, but it is non-trivial
and should probably be done separately anyway.
Local patches that had to be reapplied:
None. readline 7.0 alpha contains all of our local readline
patches.
New files in readline/:
colors.{c,h}
examples/{hist_erasedups,hist_purgecmd,rl-callbacktest,rlbasic}.c
parse-colors.{c,h}
readline.pc.in
configure.ac
Deleted files in readline/:
configure.in
Regressions:
After the sync there is one testsuite regression, the test
"signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously,
the readline 6.2 SIGINT handler would temporarily reinstall the
underlying application's SIGINT handler and immediately re-raise SIGINT
so that the orginal handler gets invoked. But now (since readline 6.3)
its SIGINT handler does not re-raise SIGINT or directly invoke the
original handler; it now sets a flag marking that SIGINT was raised, and
waits until readline explicitly has control to call the application's
SIGINT handler. Anyway, because SIGINT is no longer re-raised from
within readline's SIGINT handler, doing "signal SIGINT" with a stopped
inferior gdb process will no longer resume and then immediately stop the
process (since there is no 2nd SIGINT to immediately catch). Instead,
the inferior gdb process will now just print "Quit" and continue to run.
So with this commit, this particular test case is adjusted to reflect
this change in behavior (we now have to send a 2nd SIGINT manually to
stop it).
Aside from this one testsuite regression, I personally noticed no
regression in user-visible behavior. Though I only tested on x86_64
and on i686 Debian Stretch.
Getting this kind of change in at the start of the GDB 7.11 development
cycle will allow us to get a lot of passive testing from developers and
from bleeding-edge users.
readline/ChangeLog.gdb:
Import readline 7.0 alpha
* configure: Regenerate.
* examples/rlfe/configure: Regenerate.
gdb/ChangeLog:
* completer.c (gdb_printable_part): Sync with readline function
it is based off of.
gdb/testsuite/ChangeLog:
* gdb.gdb/selftest.exp (test_with_self): Update test to now
expect the GDB inferior to no longer immediately stop after
being resumed with "signal SIGINT".
