Hi Arun,
Thank you for submitting a patch! I've been wanting something like this
for a long time, so I'm very happy to see it. I'll test it out and let
you know if it works for me.

If someone was relying on the previous behavior (in which pcsc-lite
would look in /var/lib/pcsc/drivers for drivers), this would break for
them if they were using anything other than the ccid drivers, right?
However, I understand that previous Guix email threads have talked about
adding a symlink there which points to ccid's drivers (I do that today,
myself), so I can see why you would want to make this change.

What problem does this pcsc-lite-bootstrap package solve? It looks like
you added pcsc-lite-bootstrap in order to avoid a cyclic dependency
between ccid and pcsc-lite. That seems fair, but is there any other
reason that I'm missing?
> Subject: [PATCH 2/2] gnu: services: Add pcscd service.
Do you know what the intent behind the --enable-usbdropdir option is in
(1) the pcsc-lite configure script and (2) the ccid configure script? I
checked the README in the source for both of these packages, but I
couldn't quite understand the intended use. It wasn't clear to me if
the usbdropdir directory is where the ccid/pcsc-lite expect to _find_
drivers that the user makes available, or if this directory is where the
packages will _install_ their own drivers (or both, perhaps).
If the usbdropdir is intended to house additional drivers that the user
can "drop" in and use at runtime, then users of pcsc-lite/ccid might
reasonably expect to be able to easily add additional drivers to the
default configuration. If that's the case, then we might want to think
about how we can give a user the ability to configure additional
drivers. For example, if we gave the pcsc service configuration a field
like "usbdropdir-drivers" (e.g. a list of packages or file-like
objects), we could arrange for the union of those drivers to be placed
into the usbdropdir for pcsc/ccid to use.
Of course, I might be totally misunderstanding the intended use of the
--enable-usbdropdir configuration option. If that's the case, please
let me know.
What do you think?

No, there is no other reason. I only created pcsc-lite-bootstrap to
avoid a circular dependence between ccid and pcsc-lite.

I thought about this too. As far as I understood, the usbdropdir of the
ccid package is where it installs its drivers, and the usbdropdir of the
pcsc-lite package is where it expects to find drivers.

Good idea. I'll add a usb-drivers configuration field and send an
updated patchset.

Hi Arun,
Thank you for the update! I'm having a little trouble testing this on
my system due to the following unrelated bug:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28144
However, I'll keep trying and let you know once I've tested it out. For
now, here's my feedback.
Overall, this looks good to me. Mainly, I'd just like to test it before
we commit it to master. If you're feeling up to it, it would be great
to add a system test, but it's not necessary, and we could add it later.

Shouldn't we also export pcscd-configuration-pcsc-lite and
pcscd-configuration-usb-drivers? We allow users to set them when
constructing the record, so it seems reasonable to allow users to get
them, to. After all, if a user wants to construct a new
<pcscd-configuration> from an existing (e.g., using "inherit"), they
might need to be able to get the original values (e.g., to add more
packages to the usb-drivers list).

Does this work as written? The make-forkexec-constructor and
make-kill-destructor procedures are exported in (shepherd service), but
it doesn't look like that module will be used, since it isn't in the
modules list. If it does work, then I don't understand how (shepherd
service) is getting used, so I'd be curious to know why it works!

What happens if the symlink target already exists? Will this crash the
init process, or will the system come online and just report an error?
Some people (such as myself) have already created this directory
manually, so the directory might exist if they forget to delete it.

Yes, the service does work. But, I don't really know why. I copied this
bit of code from some other service and modified it incrementally until
it did what I wanted. :-P So, I'm not super-clear what exactly is
happening here.

When the symlink already exists, the system reconfigures properly, but
reports an error. You will have to delete your existing /var/lib/pcsc
symlink before reconfiguring.

Hi Arun,
It turns out that when we run pcscd in the foreground with the -f
option, it won't emit messages to syslog. Instead, it emits messages to
stderr, and those messages will not be stored in logs, as explained in
the following bug report:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30939
To ensure users can easily find the messages, I think we should avoid
using the "-f" option.
In addition, pcscd logs its PID to /var/run/pcscd/pcscd.pid. To ensure
that Shepherd can still tell if the service is alive even when we do not
run it in the foreground, we should invoke make-forkexec-constructor
with the #:pid-file keyword argument.
Could you make those last couple changes? Everything else looks great!

I was successful in testing it. The service works for me!

It would be good to have a system test that verifies that pcscd has
successfully started. Even such a simple test would be useful, since it
would catch a certain class of problems. There are a lot of existing
examples in the gnu/tests directory. I recently added a test like this
for the tor service, which you can find here (I haven't committed it to
master yet):

I've looked into this. The reason it works is because the "start"
field's g-expression is expanded into the Shepherd's configuration file
(see: (guix) Shepherd Services), which is evaluated in a context where
bindings from the (shepherd service) module are available (see:
(shepherd) Invoking shepherd). Therefore, the "start" field's
g-expression can use procedures from (shepherd service), such as
make-forkexec-constructor, regardless of what is listed in the "modules"
field.

OK. As long as there's a useful error message, that's good!

Great! Thank you. I look forward to getting the service itself into
master, also!

Without the '-f' option, pcscd would return immediately, and thus
calling MAKE-FORKEXEC-CONSTRUCTOR wouldn't make sense. Instead, you
could just INVOKE it. See the 'prosody', 'postgres' and 'nginx'
services for examples. And you could stop it by sending SIGTERM to the
PID in /var/run/pcscd/pcscd.pid I guess.
Also, the systemd unit files I've seen use the '--auto-exit' and
'--hotplug' options. Do you know if they make sense for us?

Thank you for mentioning this. You make a good point. I'm not yet
familiar with all the different ways Shepherd manages its herd of
processes. For example, I know Shepherd looks for the #:pid-file when
first starting the process to determine whether it started up
successfully. However, I don't know if Shepherd uses that PID file for
anything else while managing the process later on.
In any case, the procedure make-forkexec-constructor seems to hide a lot
of the nitty gritty details (e.g., closing file descriptors), so I think
it would be better to use it instead of invoking pcscd on our own if we
don't have to.
Perhaps we can do the following:
* Run pcscd in the foreground (with -f).
* Use make-forkexec-constructor.
* Tell Shepherd about the PID file via the #:pid-file option to
make-forkexec-constructor.
* Redirect pcscd's stdout/stderr to /var/log/pcscd via the #:log-file
option to make-forkexec-constructor.
That way, we can still use the convenient make-forkexec-constructor
procedure, Shepherd will still be able to manage the process, and people
will be able to find the logs more easily.
What do you think?
> Also, the systemd unit files I've seen use the '--auto-exit' and

These options are interesting, but I don't think they're useful for us
at this time.
Judging by the manual, it looks like the "--auto-exit" option is
intended to be used when a mechanism exists for automatically starting
pcscd on demand (maybe when a user plugs in a security token?), so you
don't need to keep it running all the time. We don't have a mechanism
like that at this time.
As for the "--hotplug" option, it looks like it's intended to be used to
tell a running pcscd to re-read its configuration file. However, since
that configuration file is an immutable file in the store, it isn't ever
going to change.
Maybe in the future we can think of helpful ways to use these options,
but for now I think it's OK to omit them.

When using MAKE-FORKEXEC-CONSTRUCTOR, yes. And it makes sense only for
blocking processes, because they are 'dumb', they don't return
information about whether they have succesfully started or not.
However, 'pcscd' is smart, it does return '1' if it failed to start, and
'0' if it started successfully. So, all the logic (the pid check and
everything) is done within 'pcscd' itself, no need for the Shepherd to
do it.
(start (pid-of smart-nonblocking-process)) == (start (make-forkexec-constructor dumb-blocking-process))
> However, I don't know if Shepherd uses that PID file for anything else

No, it doesn't use the #:PID-FILE argument for anything else. However,
it does use the return value of the start procedure as a PID file to
automatically respawn the service if it's an integer. So you just need
to return (call-with-input-file pid-file read) instead of #t if you want
automatic respawning, as in
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=fdbca05d78d091bfc075e54c9fb90125262eadf0.

All this stuff is done by 'pcscd' when run without '-f', using
MAKE-FORKEXEC-CONSTRUCTOR doesn't help in any way. Moreover, we do lose
the 'syslog' feature if we use it.

I think it's better to use syslog ;-) By the way, 'syslogd' should be
added as a requirement I think.

Note that the 'running' slot would then have the PID value, and
'make-kill-destructor' would work, so no need to change the stop
procedure.

Please find attached an updated patch. I have used invoke instead of
make-forkexec-constructor. I have also used (call-with-input-file
"/var/run/pcscd/pcscd.pid" read) so that shepherd knows the correct
PID. I hope I have followed your discussion correctly. Let me know if
this patch is satisfactory.
I am working on a simple test for this service. I will hopefully be done
and send you a patch for the same within 24 hours.

Hi Clément and Arun,
Clément, your explanation makes sense. With that information, I now
understand why it isn't necessary to use make-forkexec-constructor in
this case. Thank you for taking the time to explain it in detail!

Awesome!

If you use the #:requirements keyword argument to
marionette-operating-system, you can guarantee that the marionette
service will start up after the pcscd service. This would be good in
order to avoid the possibility that you might marionette-eval something
before the pcscd service is started.
With that small change, if the system test passes, I think this is good
to go to master. Thank you for taking the time to work on this and
iterate through the feedback!
