assuan: Fix exponential decay for first second.
* common/asshelp.c (wait_for_sock): Round SECSLEFT.
* dirmngr/dirmngr.c (main): Take care of --debug-wait also in dameon
mode.
* common/sysutils.c (gnupg_usleep) [HAVE_NANOSLEEP]: Fix nanosleep use.
--

Without the rounding we saw in verbose mose

 [...]to come up ... (5s)
 [...]to come up ... (4s)

immediately without the expected one second delay.  Waiting for the
next seconds did not work if nanosleep was used due to improper passed
parameters in gnupg_usleep.

Adding --debug-wait for dirmngr in daemon mode is required to test
this change.

dirmngr: Keep track of domains used for WKD queries
* dirmngr/domaininfo.c: New file.
* dirmngr/Makefile.am (dirmngr_SOURCES): Add file.
* dirmngr/server.c (cmd_wkd_get): Check whether the domain is already
known and tell domaininfo about the results.
--

This adds a registry for domain information to eventually avoid
useless queries for domains which do not support WKD.  The missing
part is a background task to check whether a queried domain supports
WKD at all and to expire old entries.

used by gpg for non-important requests (e.g. looking up a key for

--

This option allows for runtime switching to the system's standard
resolver.  This is mainly useful to work around possible bugs in the
optional resolver libraries (as of now ADNS).  Note that on Windows
there is no code to use systems's resolver and thus for full
functionality dirmngr must be build with a separate resolver.

This patch also does way with configure options to disable the use of
CERT and SRV records.

dirmngr: Lazily launch ldap reaper thread.
* dirmngr/dirmngr.c (main): Avoid calling ldap_wrapper_launch_thread()
Before we need it.
* dirmngr/ldap-wrapper.c (ldap_wrapper): Call
ldap_wrapper_launch_thread() just in time (before any attempt to use
an ldap subprocess).

--

A dirmngr process that never looks anything up in LDAP has no need for
a reaper thread, but one was started automatically.  This thread wakes
up every two seconds to look for ldap processes that might never have
been running.  We won't start more than one reaper thread for any
given dirmngr due to the static int "done" in
ldap_wrapper_launch_thread(), so it's safe to call this every time
there is a use of ldap_wrapper.

If someone wants to do further dirmngr optimizations for ldap users,
the reaper thread itself could use dynamically-calculated timeouts
(and probably needs to be alerted dynamically when a new ldap
subprocess is available so it can re-calculate those timeouts).

Note: It's not clear to me how to test ldap access effectively; i know
of no public ldap services that i can verify against, and i do not run
my own ldap servers.  If someone has a publicly-available ldap server
that developers can run tests against, i would be happy to hear about
it.

dirmngr: Use a longer timer tick interval.
* dirmngr/dirmngr.c (TIMERTICK_INTERVAL): Always use 60 seconds like
we did for WindowsCE.
--

Given that the timer tick is only used for housekeeping tasks and
these are done every 10 minutes, it makes no sense to use 2 seconds.
The minor drawback is tha the housekeeping may be delayed by one
minute.

NB: For the purpose of power saving, we already make sure that the
process wakes up at the full second so that it is synchronized to the
wakeup time of other processes.

dirmngr: More w32 system daemon cleanup
* dirmngr/dirmngr.c (handle_tick): Remove w32 tests for

--

In d83ba4897bf217d1045c58d1b99e52bd31c58812, we removed the
Windows-specific system daemon features, where shutdown_pending was
set from w32_service_control().  shutdown_pending is now never
assigned outside of handle_signal() or within an inotify test, neither
of which are available on w32.

As a result, this stanza in handle_tick() should be dead code, and can
be removed to keep things simple.

dirmngr: Register hkp-cacert even if the file doesn't exist yet
* dirmngr/dirmngr.c (parse_readable_options): If we're unable to turn
an argument for hkp-cacert into an absolute filename, terminate
completely.
* dirmngr/http.c (http_register_tls_ca): Show a warning if file is not
immediately accessible, but register it anyway.

--

Without this changeset, the condition of the filesystem when dirmngr
is initialized will have an effect on later activities of dirmngr.

For example, if a file identified by a hkp-cacert directive doesn't
exist when dirmngr starts, dirmngr will behave as though it simply
didn't have the hkp-cacert directive set at all, even if the file
should appear later.

dirmngr currently behaves differently if no hkp-cacert directives have
been set then it does when at least one hkp-cacert directive has been
set.  For example, its choice of CA cert for
hkps://hkps.pool.sks-keyservers.net depends on whether a TLS CA file
has been registered.  That behavior shouldn't additionally depend on
the state of the filesystem at the time of dirmngr launch.

"dirmngr --supervised" is a way to invoke dirmngr such that a system
supervisor like systemd can provide socket-activated startup, log
management, and scheduled shutdown.

When running in this mode, dirmngr:

 * Does not open its own listening socket; rather, it expects to be
   given a listening socket on file descriptor 3.

 * Does not detach from the invoking process, staying in the

096e7457ec Change all quotes in strings and comments to the new GNU standard.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems.  We now use two \x27 characters ('...').

The proper solution would be to use the correct Unicode symmetric
quotes here.  However this has the disadvantage that the system
requires Unicode support.  We don't want that today.  If Unicode is
available a generated po file can be used to output proper quotes.  A
simple sed script like the one used for en@quote is sufficient to
change them.

The changes have been done by applying

  sed -i "s/\`\([^'\`]*\)'/'\1'/g"

to most files and fixing obvious problems by hand.  The msgid strings in
the po files were fixed with a similar command.
