Gnome-shell-extension-gsconnect: Document and finalize CLI usage

[andyholmes]

We should document the CLI interface in the wiki, finalize the options so it's relatively stable, and probably test it.

It would probably be nice to have a few example scripts that can be used with the runcommand plugin, but becoming a repository for them sounds like a bad idea, due to reviewing/security/etc.

A start is here: CLI Scripting

[ferdnyc]

Reading the help listing, one thing I'd suggest is grouping the device actions separately, to make it clear they all require a -d / --device argument as well. So, maybe something like:

$ ./daemon.js --help
Usage:
  GSConnect [OPTION…]

Help Options:
  -h, --help                          Show help options
  --help-all                          Show all help options
  --help-gapplication                 Show GApplication options
  --help-gtk                          Show GTK+ Options

Application Options:
  -l, --list-devices                  List available devices
  -a, --list-all                      List all devices
  -v, --version                       Show release version
  --display=DISPLAY                   X display to use
  -d, --device=<device-id>            Target Device

Device Actions (with --device):
  --pair                              Pair
  --unpair                            Unpair
  --message=<phone-number>            Send SMS
  --message-body=<text>               Message Body
  --notification=<title>              Send Notification
  --notification-appname=<name>       Notification App Name
  --notification-body=<text>          Notification Body
  --notification-icon=<icon-name>     Notification Icon
  --notification-id=<id>              Notification ID
  --photo                             Photo
  --ping                              Ping
  --ring                              Ring
  --share-file=<filepath|URI>         Share File
  --share-link=<URL>                  Share Link

[andyholmes]

Unfortunately I don't think we can make our own groups, since the only way to add options to a GOptionGroup is using GOptionEntry which is a bare struct type. Probably GOptionEntry would have to be turned into a boxed type in GLib with a constructor func.

[ferdnyc]

Mmm, so I see. An issue that was identified 5.5 years ago. How special.

...But I seem to be having bigger problems with even the _single_ group. I tried to run ./daemon.js --help in the v29 release extension dir, and found it was dying when it couldn't find a schema file:

$ ./daemon.js --help

(gjs:420030): Gjs-WARNING **: 20:34:15.913: JS ERROR: GLib.FileError: Failed to open file “/usr/local/share/glib-2.0/schemas/gschemas.compiled”: open() failed: No such file or directory
@/home/ferd/rpmbuild/REPOS/gsconnect/extensions/[email protected]/_gsconnect.js:80:25
@./daemon.js:29:1

Script ./daemon.js threw an exception

I poked around and found that's because there are /usr/local/... paths in metadata.json, which of course on Fedora are totally wrong. So I edited those to remove the .../local... part, and now it's just segfaulting _silently_ on me:

$ ./daemon.js --help 
zsh: segmentation fault (core dumped)  ./daemon.js --help

GJS apparently has a very euphemistic notion of what a "debugger" is, because I tried to run the code in its debugging mode and it _still_ died on the same segfault:

$ gjs -d ./daemon.js --help
GJS debugger. Type "help" for help
db> c
zsh: segmentation fault (core dumped)  gjs -d ./daemon.js --help

IT BROKEN. :cry:

[ferdnyc]

Hah! Turns out, it was this:

@/home/ferd/rpmbuild/REPOS/gsconnect/extensions/[email protected]/_gsconnect.js:80:25

extensions is symlinked to my $HOME/.local/share/gnome-shell/extensions, but it seems the relative path matters because if I cd to the extension directory _directly_ instead of through that symlink, everything works fine. D'oh.

[andyholmes]

Hmm, if you're using rpmbuild that fedora uses, it looks a little eccentric to me. Generally those paths should be set properly by the meson.build.

That's weird that it segfaults, but fyi you can just run GJS apps with gdb as normal to track it down.

EDIT: er, less normal actually, but something like gdb --args /usr/bin/gjs daemons.js should work. Of course, now that I do that I notice we're probably using way to many threads here :/

[ferdnyc]

Hmm, if you're using rpmbuild that fedora uses, it looks a little eccentric to me. Generally those paths should be set properly by the meson.build.

Oh, I'm not actually building RPMs in this case, all of my development work lives in $HOME/rpmbuild/REPOS/ for... historical reasons. (read: No good reason.)

Even in v29 and v30 downloaded from e.g.o the metadata.json file contains /usr/local/ paths, tho:

[ferdnyc]

(At least it's /usr/local/lib64... if Ubuntu and Debian users get the same thing, it'll be even _wrong_-er for them as their arch libdir is /usr(/local)?/lib/x86_64-linux-gnu/.)

[andyholmes]

That's correct. If you're installing as a user extension those directories aren't used because we know where the files are. It would be impossible to pre-populate those with values that worked for every distribution, and we can't install files to those directories anyways, since we're unpriviledged.

[ferdnyc]

Huh. In fact, it seems trying to run daemon.js --help from a _build directory also crashes. If it's run _with_ the correct paths in the generated metadata.json, it's the same silent segfault:

$ meson _build .
$ meson configure --prefix=/usr _build
$ ninja -C _build make-zip
[...]
$ cd _build/[email protected]
$ ./service/daemon.js --help
zsh: segmentation fault (core dumped)  ./service/daemon.js --help

Bit odd, but not really important I guess. It works where it's supposed to.

[andyholmes]

What happens when you run it with gdb --args /usr/bin/gjs?

[ferdnyc]

Same, I'm waiting on it loading debug symbols now for the backtrace...

Well, that's long enough to be basically useless.

I do notice, though, that it seems to be something in _gsconnect.js that's triggering the segfault, not daemon.js.

[andyholmes]

Interesting, I assume you're running GJS 1.58 and/or GNOME 3.34? We added overrides to prevent these crashes, but maybe we forgot GSettingsSchema and only did GSettings. In either case, I bet this is because _gsconnect.js is not finding the correct directory for the settings schema and/or its not compiled by this time.

[ferdnyc]

Running 1.58.3 under 3.34.1, yep.

[andyholmes]

Okay, I'll submit a PR to GJS later today sometime.

Going to close this since I think I've added everything that makes sense to the CLI options. When I remember I'll try and add some more examples to the Wiki, but otherwise I think this should be good for now.
