Subject: [PATCH 0/6] Adopt NixOS patches for Qt5
Date: Sat,  3 Feb 2018 20:22:12 +0100

I reviewed the patches NixOS aplies to Qt 5.9 and 5.10. The changes of this
series hold the result. I stepped over these when trying to make KDE Plasma
work.

Most changes are about using store-paths to other packages and for dynamically
loaded libs.  To ease futuer work, I also added comments about patches we do
not need and why.


Hartmut Goebel (6):
  gnu: qtbase: Use the store paths for other packages and dynamically
    loaded libs.
  gnu: qtdeclarative: Add note about a patch NixOS has but we don't
    need.
  gnu: qtscript: Add note about a patch NixOS has but we don't need.
  gnu: qtserialport: Use the store paths for dynamically loaded libs.
  gnu: qttools: Add note about a patch NixOS has but we don't need.
  gnu: qtwebkit: Add note about a patch NixOS has but we don't need.

Subject: [PATCH 1/6] gnu: qtbase: Use the store paths for other packages and
 dynamically loaded libs.
Date: Sat,  3 Feb 2018 20:25:00 +0100

Adobt the NixOS patches as of 2018-01-19:

- .cmake.in and .prf files are not patches.

- src/corelib/tools/qtimezoneprivate_tz.cpp: NixOS uses $TZDIR, we use
  hardcoded path to tzdata.

- src/corelib/kernel/qcoreapplication.cpp: NixOS adds plugin paths derived
  from PATH. We do not need this, since we have native-search-path
  QT_PLUGIN_PATH.

- src/network/kernel/qdnslookup_unix.cpp,
  src/network/kernel/qhostinfo_unix.cpp: Use hardcoded path to libresolv.

- src/network/ssl/qsslcontext_openssl.cpp: NixOS changes a conditional
  compilation for Qt 5.9 (but leaves it unchanged for Qt 5.10) to fix
  compilation with libressl.  But Qt does not support libressl anway, see
  config.tests/openssl/openssl.cpp in qtbase 5.9.4.

- src/plugins/platforminputcontexts/compose/generator/qtablegenerator.cpp:
  Use hardcoded path to libx11.

- src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp:
  Use hardcoded path to mess's libGL, no need for a fall-back.

- src/plugins/platforms/xcb/qxcbcursor.cpp: Use hardcoded path to Xcursor.

- src/plugins/platformthemes/gtk3/main.cpp: NixOS changes $XDG_DATA_DIRS and
  $GIO_EXTRA_MODULES in the code. We use search-path-specification for this.

- src/testlib/qtestassert.h: Unchanged for guix.

* gnu/packages/qt.scm (qtbase) Add comment. [inputs]: Add tzdata.
  [aguments]<phases>: Add 'patch-paths'.

I'm afraid, I don't understand this question. I don't know if "this is
really required", otherwise I would not have put the comment there.

Hi Hartmut,

Oh, I thought you investigated or asked someone upstream about it.

I don't know Qt interna so well - but it would be possible to ask upstream.

The part under discussion is

static bool resolveLibraryInternal()
{
    QLibrary lib;
#ifdef LIBRESOLV_SO
    lib.setFileName(QStringLiteral(LIBRESOLV_SO));
    if (!lib.load())
#endif
    {
        lib.setFileName(QLatin1String("resolv")); <-----
        if (!lib.load())
            return false;
...

so I guess it can't hurt to substitute something in the line with the arrow,
but LIBRESOLV_SO is more important, right?

Why hardcode the path?  We set TZDIR as well in (gnu system).

Is there any reason we cannot add these libraries to RUNPATH instead?

Thanks a lot for this valuable hint! I investigated this:

1) LIBRESOLV_SO seems to be not defined. The reason seems to be that
__GNU_LIBRARY__ is not defined and thus gnu/lib-names.h is not included.
(I grepped the code and build-reesults just after the build stage.)

2) Even if LIBRESOLV_SO would be defined, we would need to append the
store path. (No problem, though.)

Any idea how to solve 1)?

I don’t understand all of this (does it describe problems or solutions?
what does it mean “files are not patches”? etc.) and I think we should
describe the problems/solutions on their own, without “NixOS does this”
comments, which isn’t really helpful IMO.

As an aside, I think explanations when they’re needed, should go in the
source, not in the commit log.

That makes sense to me, and actually, I don’t think it needs more
explanations.  :-)

Did you notice improvements on KDE applications?

So, LGTM!

Are you referring to patch (1/6)? Or do you mean patches 2, 3, 5 and 6
are unnecessary?

I do not care about the comments, but FMPOV it is important to document
somehow in the code or in the commits that all patches as of 2018-01-19
have been considered. an alternative would be to group these few commits
into a (very short) branch and documenting the fact in the merge-commit.

WDYT?

The upstream code (qt.com) uses hard-coded path (/usr/share/zoneinfo/),
so for me it seems to be much more natural to simply change this - and
stay closer to upstream. NixOS seems to require TZDATA since some things
work differently compared to guix. E.g. nixos is deriving library search
paths from $PATH in some other patch. This is something guix does not need.

Rethinking this, this comment is wrong and I'll correct it. QLibrary
(which is used an all these cases) is documented with:

    When loading the library, QLibrary
    <http://doc.qt.io/qt-5/qlibrary.html> searches in all the
    system-specific library locations (e.g. |LD_LIBRARY_PATH| on Unix),
    unless the file name has an absolute path.

But guix does not set LD_LIBRARYPATH (e.g. in "guix environment"), thus
we need to have absolute paths for the libraries.

Does this make sense?

My idea is to use the commit message to document: "We reviewed the NixOS
patches as of 2018-01-09, and this is what we decided how to handle the
respective changes." (This might still be worth rewriting.) This will
give confidence that all patches are considered to the ones working on
this next.

In contrast the code comments only document the actual code for the case
one doesn't cares about how/whether the code follows NixOS. (As you
already commented.)

 you mean patches 2, 3, 5 and 6 are unnecessary?

I'm not even sure it we'd better remove all the refernces to NixOs from
this change and only document it in commit messages. We could group
these few commits into a (very short) branch, drop patches 2, 3, 5 and
6, and documenting "considered all NixOS patched: Not needed, … etc." in
the merge-commit:

* Merge branch 'nixos patches for Qt 5.9' into master.
|\
| * gnu: qtserialport: Use the store paths for dynamically
| * gnu: qtbase: Use the store paths for
|/


The comments currently in patch 2, 3, 5, and 6 would into the Merge
commit's message.

WDYT?

> I think you can remove “TODO” here.
ACK.

> Did you notice improvements on KDE applications?

KDE Plasma feels to be more stable with these changes applied. I can't
proof it's these changes, since I have a similar series for KF5.

I don't think the comments are all that useful.  They only add noise in
the commit log and the code -- since we have a working and up-to-date
Qt, it is implied that we don't need anything more from NixOS or
elsewhere.

For tzdata in particular, we are trying to reduce the number of
dependent packages so that we can update it directly on 'master'.  Often
a new tzdata release introduces changes with near-immediate effects, so
it's important to be able to update it fast.

Adding it to qtbase would add 282 new dependent packages, which is
unfortunate.  So I much prefer using TZDIR, even though it would be
technically better to reference it directly.

IC. Should not be much of a problem to adopt the actual patch from NixOS.

But I wonder: How is ensured that timezone is installed e.g. in an `guix
environment`, if there is no dependency?

Good question.  I suppose we could add a search path for TZDIR so that
the variable gets set as long as you include tzdata in the environment.

I don’t have much to add.  It’s good to add comments for things that
aren’t obvious by looking at the ‘substitute*’ sequences, but for
obvious things it’s “noise” indeed.

At any rate, this shouldn’t hold the patches back.

Thanks,
Ludo’.

This is a wise, while abstract answer. :-) Unfortunately it does not
help me to decide and finish the patches. :-\

- Should I keep or drop these "Add note about a patch NixOS …" patches
(2,3,5,6)
- If dropping: Should I use a short living branch as described in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30340#62

Hi Hartmut,

IMO yes.

IMO no—as you know we keep the history linear whenever possible.

At the end of the day, what matters is that these patches get in.  We
shouldn’t spend so long rehashing our views on how to write comments.

Also, you have commit access because as a group we trust you to be able
to make simple decisions in line with the group conventions and
practices.  Once you’ve had initial feedback, you should feel empowered.

Thanks for working on this!

Ludo’.

I finally pushed this as bdf0c644d..042f7c263. Changes to the original
patches are:

* qtbase:
  - Don't use tzdata as input, adopt patch for using TZDIR instead
  - Update comment why store-paths are needed
* qtserialport:
  - Update comment why store-paths are needed
* drop patches 2, 3, 5 and 6 (Add not …)
