qtwenengine anybody?

[Hartmut Goebel]

Hi Guix!

Looks like we need to package qtwebengine, as more and more packages
require it.
qtwebengine includes a copy of chromium.

Any volunteers?

Mike Rosset had it working in a patch that's still waiting on the tracker.
It has at least one issue as far as I get it.  Mike also made an
all-in-one "Qt" package that does not suffer from this issue, a bit like
our texlive mega-package.

I'm all for adding it to master.

Thanks for forwarding this to me Pierre. The new monolithic QT packages
with qtwebengine is derived from the now deprecated qt package, which
has since been removed from guix, which is understandable since the
module packages are more ideal.

This new monolithic package stills suffers from the same issue as my
modular qtwebengine. In that there are many in tree third party
dependencies. It's not trivial to simply switch to guix inputs for
these.

This package is an improvement on my module qtwebengine package. Since
it does not suffer from the same locales issues.

Mike, can you give some details (maybe one example) on how to replace the
third-party dependencies?  What is holding it back?

I could give it a go if need be.

I have not tackled this problem yet. I've mainly been focused on get the
package to build. I've fixed the most blaring issue. For example the
package now builds in parallel which improves build times significantly.

In terms of resolving the in tree dependencies. Some can be resolved
using QT configure flags. I don't think I've ported these over from my
module qtwebengine but I will check this when I have time.

The other third party dependencies might need header and gn
substitutions. A good place to start is the ugoogled-chromium package as
to how this is done. Though it might take more work for qtwebengine
because of QT configure and build changes. That's about as far as I got
with looking at this.

Hi,

I'm glad to see there already has been some effort on this. I'll comment
on the issue.

IMO we should focus on a stand-alone qtwebengine package to avoid having
packages depending on a *huge* monolith.

This is the most ideal situation. However the modular qtwebengine makes
some assumptions which are not compatible with guix. For examples it
assumes it will be installed in the same prefix as qtbase. Which is not
possible with guix. The problem is also not readily obvious until you
try to use qtwebengine in a library or a program. Which will causes
locale and translation path issues.

For the nomad browser I had had some hacks to get around this. But those
hacks won't work in all cases. Because it's dependent on arg0
location. Which is not consistent when using an interpreter like guile
or python or if you are using qtwebengine from a dynamic library.
As of yet I have not found a proper way to resolve this.

I believe the monolithic qt package at this time is the shortest route
to having a sane working qtwebengine, until the locale issues can be
resolved.

If the only issue with qtwebengine are locale and translation, I suggest
to accept these for now. IMHO we need to attract more users (and
developers) for guix, fir which we need more packages.  And missing
qtwebengine blocks some KDE applications form getting build for guix.

IMHO the locale, translation would be a blocker still. Because it will
cause programs to fail. It's not just a locale/translation warning.

I'm currently brushing up my latest qtwebengine build. Will resubmit
this patch. I will also see if I can inherit qtsvg again to put this
back on par with other module packages. From there I'll put a simple
test example together demonstrating the locale and translation problem.

I've resubmitted the patch it can be found here
https://lists.gnu.org/archive/html/guix-patches/2019-12/msg00530.html. My
ML patch workflow is probably not all that correct so I apologize if
there is any issues.

To summarize the package now inherits from qtsvg. The locales issues
have been resolved by substituting qtwebengine's output instead of using
qtbase.

Some dynamically loaded libraries like udev and nss have been
substituted using corresponding inputs.

Some known issues, when building with pulseaudio support. There is some
issues finding pulseaudio socket. I've disabled support for pulseaudio
until I can resolve this.

Additionally on my system when using hardware accelerated OpenGL
neuveau drivers, qtwebengine crashes this does not happen when using the
monolithic qt package. This can avoided by setting the
QT_XCB_FORCE_SOFTWARE_OPENGL to 1.

I have a simple CPP for testing it can be found
here. https://github.com/mrosset/testqt.

for testing I use this enviroment.

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix environment  --ad-hoc qtbase qtwebengine qtdeclarative qtwebchannel coreutils gcc-toolchain nss-certs
--8<---------------cut here---------------end--------------->8---

and then I test with

--8<---------------cut here---------------start------------->8---
cd testqt
qmake
make
./main
--8<---------------cut here---------------end--------------->8---

or there are hardware acceleration problems

--8<---------------cut here---------------start------------->8---
QT_XCB_FORCE_SOFTWARE_OPENGL=1 ./main
--8<---------------cut here---------------end--------------->8---

I can also a substitute if anyone needs them for testing. Since this
build can take some time.

Fantastic!

The pulseaudio and OpenGL issues are not blockers in my opinion.  We can
open new issues about them and resolve them later.

A substitute is available on https://gx.bufio.org and the public key can
be found
here. http://git.savannah.nongnu.org/cgit/nomad.git/plain/contrib/guix/gx.bufio.org.pub

This should be resolved now. I had to upgrade the vps to avoid OOM
issues. But as I've now it should serve this substitute.

you can test with.

guix archive --export -r qtwebengine | ssh server guix archive --import

If this passes make sure you have

Sorry, still no substitute for me for the patch you've sent yesterday.

I tested with a couple of machines and it does server substitutes. maybe
now the substitute cache will have invalidated. or you can manual purge
/var/guix/substitutes.  Hopefully this resolves it self. If not I'm
going to have a new build soon that fixs pulseaudio and the other issues
you mentioned on the bug tracker.

I was not quite clear here. For me it's easier to build on
workstation. And then I'd like to export to my publish server. But
simply exporting and importing does cause the publish to server the
build as a substitute. Maybe this is not feasible or I misunderstand how
to do this.

 g++: internal compiler error: Killed (program cc1plus) . does look like
 a oom error. I noticed with this build if you have many cores it needs
 quite alot of ram. I mainly build on a 6 core with 6 threads AMD Ryzen
 5 3600 Processor and 16 gigs of ram with a 1TB nvme drive. Build time
 is roughly 40min.

I remember an issue was raised regarding the embedded third-party
libraries in the package (I think src/3rdparty).

Any plan regarding this?  Is there anything that cannot be replaced by a
Guix input?

This is surprising but good news none the less. Also I've mailed a
second in the series patch that fixes pulseaudio and address your
comments in the bug tracker. A substitute should be provided for this as
well.

Hmm... On second though, I just navigated GNU.org, which might not
require GL acceleration.  I think I should try with a proper GL test website.

For me the GL issues will cause issues regardless of the website. For
example you can not scroll the page. But the symptoms may changed
depending on video drivers. Let know how this turns out.

I tested again on an Intel HD Graphics 620.
Everything works for me so far (navigating, smooth scrolling, rendering).

I tested the following:

- https://gnu.org
- https://ambrevar.xyz (has some CSS that may required hardware acceleration)
- https://github.com
- https://youtube.com: playing videos works flawlessly.
- https://get.webgl.org/: the webgl cube is spinning properly :)

Mike, have you tried building the package against ungoogled-chromium?

Either way, I vote for including this package into Guix, it seems mature enough.
We can open an issue to replace the bundled chromium with
ungoogled-chromium if need be.

Sorry for the long delay on responding to this topic. I've been pretty
busy. I have done a cursory look at upstreamn ungoogled-chrome and then
started to reason what might need to be done to integrate this into
qtwebengine.

My conclusion is this is going to be way more work then the
benefits. And once this was achieved it still needs to be
maintained. Keep in mind QT already has a patch re base process with
changes that might conflict with ungoogled-chrome. I think the better
approach is to try and fix the in tree dependencies upstream. and let it
trick down to the guix declaration.

In a more ideal world I think QT and the ungogogled project should be
working together since there goals are much on par.

Though maybe given enough time and resources I could find an more ideal
way to solve this. Right now though I don't think I have the time or
resources.

Totally, I think you are making a lot of sense here.
Since you are the most knowledgeable on the topic, would you mind
reporting this to upstream and include the links in your patch?  Thanks!

Let me know if there are more changes you'd like to include to your
patch.
If no one objects, I'll merge it within a week.

Cheers!

I think the package is looking pretty good now. I sent some changes
requested by Hartmut today so we might need to wait on any more changes
he might have.

Moving forward I'll start a discussion upstream about how to go about
improving the in tree dependency issue.

I'm going to take a further look at the nouveau issue both on guix system
and I'd like to do more testing of foreign distro.

Apologies this is probably a failure in my ML workflow. And just my luck

Many thanks, this is quite helpful.

For me it looks okay except of two minor points:

- The description should contain at least a brief note about Qt patched
the embedded chromium to (partially) un-google it. If you know details,
this would be great. This of course could be enhanced later, since
changing the description does not force a rebuild of he package.

- Please still honor Ricardo's remark about DRM and phoning home.

Hello Hartmut,

I've upgraded the description field as request see attached. And CC to
35866@debbugs.gnu.org

I've also addressed in depth some Ricardo's concerns.

More then likely you will have problems applying this with git am
again. This final declaration though based on my original
submission. Was moved manually out and back in again. So there is
probably inconsequential git history missing. I could create a new bug
report maybe? Or you can still use the complete diff from
https://gitlab.com/mike.rosset/guix/compare/master...qtwebengine

For me this would be okay. Ricardo needs to state whether his concerns
are covered.

This was perfectly fine for reviewing. Thanks.

I’m sorry for making this harder, but I would very much like to first
see evidence that the problematic features of Chromium have in fact been
addressed by QT upstream.

Does the code include DRM support, for example?  Does it phone home?
Can we see the patches that upstream applied to the Chromium sources?

I just had a quick glimpse at

  git://code.qt.io/qt/qtwebengine-chromium.git

(Branch v5.14.0.)

It has a lot of patches, but I don't understand the sources enough to
make an informed decision.

Maybe Marius or Mike can tell us more.

QtWebengine does not handle DRM at all. That is handled by a 3rd party
plugin called wildevine and would require guix to bundle that plugin.
Something I'm confident is not going to happen. As an added measure my
proposed qtwebengine declaration has pepper plugins disabled making it
impossible to load 3rd party plugins either way.

see https://doc.qt.io/qt-5/qtwebengine-features.html#html5-drm
for reference

In regards to QtWebEngine phoning home https://wiki.qt.io/QtWebEngine
states all google services have been removed. Nothing I've seen
indicates this is not the case.

In terms of patches. You can get a complete diff of chromium sources
by cloning qtwebengine recursively like so.

--8<---------------cut here---------------start------------->8---
git clone http://code.qt.io/qt/qtwebengine.git --recursive
--8<---------------cut here---------------end--------------->8---

Version 5.12.6 of qtwebengine is based on chromium sources 69.0.3497.128
to get a complete diff you can do this from the src/3rdpath directory.
you can then get a complete patch diff for version 5.12.6 like so.

--8<---------------cut here---------------start------------->8---
git diff origin/upstream-master origin/69-based
--8<---------------cut here---------------end--------------->8---

I’m aware of this.  My apologies for not expressing myself more
clearly.  We probably want to remove the support for the DRM plugin,
following the discussions about ungoogled-chromium at

    https://issues.guix.gnu.org/issue/34565

Marius Bakke does a good job of summing up DRM when closing this
issue. Widevine and DRM are not part of chromium and requires not only
the widevine binary to be installed by the user. But also in the case of
qtwebengine requires the users to rebuild the package to include pepper
plugin support. The proposed declaration uses this flag
-webengine-pepper-plugins=no which disables flash and widevine support
altogether.

see
https://code.qt.io/cgit/qt/qtwebengine.git/tree/config_help.txt?h=5.12.6#n16
for reference.

I have attached a patch that disables support for loading the Widevine
plugin, and also removes unused bundled software from the source based
on a whitelist, similar to ungoogled-chromium's
%PRESERVED-THIRD-PARTY-FILES.

It removes some 300+ MiB from the uncompressed sources.  The snippet
will require some adjustments for every new version of QtWebEngine
however, I can help out with that when required.

Patch 1/2 is a slightly "cleaned up" version of Mike's latest patch,
fixing some cosmetic issues, and makes it respect the daemons requested
number of build cores.

With these changes, I think the package is ready to go.  \o/

This is really great work Marius I appreciate this addition. I was
actually just looking at this approach yesterday. 

I've merged your two patches with one minor description addition that Hartmut
requested.

Hartmut the merged complete diff can be found here.

Great work you've done! I'm looking forward to get this merged to
master, so I can continue working on some more KDE packages.

Fine for me.

Just some super-nitpicky nitpicks:

Maybe move has into `base32` line

The "if" could be omitted, I assume

Great!  I've squashed them appropriately and finally merged qtwebengine!

I also moved the package definition alongside the other first party Qt
modules.

Now we just need some packages using it!  :-)

This was my first thought as well. Though next is also a good candidate
too? :)

If anyone is working on updating quitebrowser let me know. If not I'll
starting working on this soon.

Side note Pierre, I'll switch GIQT over to this in the next couple of
days as well.

QtWebengine support is still somewhat experimental in Next.  I haven't
worked on it directly, but I could try and see if it works on Guix.

I think updating qutebrowser to use QtWebengine should be trivial.
If you have time during the next couple of days, please go ahead :)

Hello Pierre and Marius,

I've have sent some patches to an open bug #38148 in regards to
qutebrowser being outdated. I'm hoping this will help test out
qtwebengine and close that bug. Two birds with one stone :)

The patch includes python-pyqtwebengine and upgrade of qutebrowser to
1.9.0 and it now uses qtwebengine.

If anyone can help review and make suggestions that would be great.

On second thought maybe I should have emailed them to
guix-patches@gnu.org. Let me know if that's better for reviewing.

Mike

Qutebrowser 1.9.0 works now, great job!
I've reviewed those patches; fix the few nits and I'll merge.

If you think the bug title is relevant, then it's the right thing to do.
That said, it seems that you've sent the first patch twice.  To clarify,
this is how you should proceed to send patches to debbugs:

1. Send the first patch only.  If you send with "git send-email", you
should see the message ID in the output.

2. Send all other patches by using the "--in-reply-to=$ABOVE_MESSAGE_ID"
option.  Make sure the patches are in the right order on the command
line.  Example:

  git send-email --to=38148@debbugs.gnu.org \
  --in-reply-to='<20200113103304.9093-1-mike.rosset@gmail.com>' \
  0002-patch-foo.diff 0003-patch-bar.diff
  
Hope that helps!

It's possible this can be fixed by setting QTWEBENGINEPROCESS_PATH

Maybe just

They are #include'd by some files unconditionally.  It should be
possible to #ifdef out at least widevine_cdm_common.h; I'll look into it
for the next ungoogled-chromium update.

Thanks for testing this. one site that suffers with webkit I noticed is
reddit I would add that to your test sites.

I think I found the issues nouaveau in that the those drivers currently
do not support multi threaded OpenGL which qtwebengine uses. Oddly
though I do not need to set QT_XCB_FORCE_SOFTWARE_OPENGL in my
monolithic QT package with qtwebengine. But that package is using the
latest QT 5.14.0 and it's possible it's doing some auto detection and
switching software acceleration on nouveau anyways. I'll have to
investigate this further down the road.
