[Buildroot] [PATCH 0/3 v4] package/qt5/qt5webengine: fix options and dependencies (branch yem/qt5webengine-options)

[Yann E. MORIN]

Hello All!

This series is a refresh and respin of the commits by Nathan, which got
reviewed by Peter.

I (Yann) merely did the following changes:

 1. refresh on top of master, now that we no longer have a version
    choice for qt5,

 2. split the first patch in two: the first to switch to the new options
    instead of defines, the second to add the missing dependency

As such, I did not carry Peter's review on the first patch, since I
split it.

Note: this is not even build-tested; it's just a refresh-n-respin.


Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/3 v4] package/qt5/qt5webengine: fix ffmpeg/codec/alsa option handling for latest

[Yann E. MORIN]

From: Nathan Ford <nford@westpond.com>

As of qt 5.10, options are handled as arguments to qmake instead of
defines:

    qt5webengine-5.12.2$ vi dist/changes-5.9.0

    Important Changes
    -----------------

     - Configure options are now handled by the global configure script. This
       means options previously controlled by WEBENGINE_CONFIG options should
       now use configure flags. For instance the configure command-line option
       -proprietary-codecs replaces WEBENGINE_CONFIG+=use_proprietary_codecs.

    qt5webengine-5.12.2$ vi dist/changes-5.10.0

    Important Changes
    -----------------

       * WebEngine Features are now configured as Qt features and
         WEBENGINE_CONFIG has been removed.

Fixes: #12416 (which was an inspiration for this patch)

In the original patch, there was a "--" that was added to separate
these webengine options from the main options. You have not kept that.
Are you sure this is OK ?

I am not sure, hence I said in the cover-letter "Note: this is not even
build-tested; it's just a refresh-n-respin."

I'll do a test-build tonight (I did not have spare CPU cycles yesterday,
but tonight I should have some.)

However, none of the qmake-package we have use that '--'.

Regards,
Yann E. MORIN.

I believe Thomas is right, all other qmake-packages set
an option <name>=|-=|+=<value> as the old behavior before
the patch and not the 'real' option one after the patch
(see above 'QT_CONFIG-=alsa' vs. '-no-webengine-alsa' or
in case for the first one '-- -webengine-ffmpeg'...

Peter

I am not 100% sure but I believe those dependencies do have options,
much like the -webengine-ffmpeg option that PATCH 1/3 is using. If you
look at ./src/core/configure.json in the qt5webengine sources, you can
see:

    "commandline": {
        "options": {
            "webengine-alsa": "boolean",
            "webengine-embedded-build": "boolean",
            "webengine-full-debug-info": "boolean",
            "webengine-icu": { "type": "enum", "name": "webengine-system-icu", "values": { "system": "yes", "qt": "no" } },
            "webengine-ffmpeg": { "type": "enum", "name": "webengine-system-ffmpeg", "values": { "system": "yes", "qt": "no" } },
            "webengine-opus": { "type": "enum", "name": "webengine-system-opus", "values": { "system": "yes", "qt": "no" } },
            "webengine-webp": { "type": "enum", "name": "webengine-system-libwebp", "values": { "system": "yes", "qt": "no" } },
            "webengine-pepper-plugins": "boolean",
            "webengine-printing-and-pdf": "boolean",
            "webengine-proprietary-codecs": "boolean",
            "webengine-pulseaudio": "boolean",
            "webengine-spellchecker": "boolean",
            "webengine-native-spellchecker": "boolean",
            "webengine-extensions": "boolean",
            "webengine-webrtc": "boolean",
            "webengine-geolocation": "boolean",
            "webengine-webchannel": "boolean",
            "webengine-kerberos": "boolean",
            "alsa": { "type": "boolean", "name": "webengine-alsa" },
            "pulseaudio": { "type": "boolean", "name": "webengine-pulseaudio" },
            "ffmpeg": { "type": "enum", "name": "webengine-system-ffmpeg", "values": { "system": "yes", "qt": "no" } },
            "opus": { "type": "enum", "name": "webengine-system-opus", "values": { "system": "yes", "qt": "no" } },
            "webp": { "type": "enum", "name": "webengine-system-libwebp", "values": { "system": "yes", "qt": "no" } },
            "pepper-plugins": { "type": "boolean", "name": "webengine-pepper-plugins" },
            "printing-and-pdf": { "type": "boolean", "name": "webengine-printing-and-pdf" },
            "proprietary-codecs": { "type": "boolean", "name": "webengine-proprietary-codecs" },
            "spellchecker": { "type": "boolean", "name": "webengine-spellchecker" },
            "extensions": { "type": "boolean", "name": "webengine-extensions" },
            "webrtc": { "type": "boolean", "name": "webengine-webrtc" }
        }
    },

So it seems like if we have a -webengine-ffmpeg option, then we should
also have many other options to enable (and perhaps disable ?) other
optional features.

However, I'm not sure to understand the difference between the
"webengine-<something>" option and the corresponding "<something>"
option.

Also, it seems like some options such as webengine-ffmpeg or
webengine-icu can take multiple values: they are enums and not
booleans. should we use -webengine-ffmpeg=system for example ? Ditto
for the other dependencies;

For the record, the qt5webengine source code bundles chromium in
./src/3rdparty/, which itself bundles a bunch of things including
ffmpeg in ./src/3rdparty/chromium/third_party/ffmpeg/ (do you like when
a 3rdparty folder includes another third_party folder ?).

Obviously, in the context of Buildroot, we'd prefer to use as few
bundled libraries as possible, and use as much as possible system
libraries.

How is the configure.json above being parsed and used ?

[Buildroot] [PATCH 3/3 v4] package/qt5/qt5webengine: fix build dependencies for autodetected packages

[Nathan Ford]

Hi Thomas,

In src/buildtools/configure.json some of the library dependencies have
had their auto detection disabled ( look for the key "autoDetect" in
the features section ), at least as of 5.14.2 ( I have not migrated to
newer for the projects I work on yet ).

I assumed that any lib that qt5webengine built itself was a hard
dependency, so if it is present in the buildroot build, use it,
otherwise let qt5webengine build its own. The alternative is to make
all those libs build dependencies of qt5webengine.

--Nate

[Buildroot] [PATCH 1/3 v4] package/qt5/qt5webengine: fix ffmpeg/codec/alsa option handling for latest

[Nathan Ford]

Hi All,

I can't speak for newer qt5 versions, but for 5.14.2 the -- is
required. I don't understand the qt build system well enough to
explain why.

[Buildroot] [PATCH 3/3 v4] package/qt5/qt5webengine: fix build dependencies for autodetected packages

Ah yes, there was also src/buildtools/configure.json, which I don't
know how it interacts with ./src/core/configure.json...

So, the ones that have "autoDetect": "false", it means that the build
system doesn't try to detect them, and it will only enable them if
explicitly enabled?

As much as possible we want to:

 (1) Use system libraries installed of bundled ones

 (2) Be explicit when handling optional dependencies by telling the
     build system "please enable support for FOO", "please disable support
     for FOO".

Nathan, Peter, All,

On 2020-09-17 15:23 -0400, Nathan Ford spake thusly:

As said on the cover letter, I did not even build-tested it, and just
refreshed the series, and I semi-voluntarily removed the --. I now did a
build, and they are indeed needed.

Thanks for the sharp eyes!

Regards,
Yann E. MORIN.

 Since there was quite a bit of feedback on patches 1 and 3, I've marked this
series as Changes Requested.
