Subject: [PATCH 0/6] Add hydrus network and its dependencies
Date: Wed, 27 Jul 2022 20:57:18 +0200

This patch series will add hydrus network along with all dependencies it needs and fixes
to already existing packages.
The hydrus-network package added in the last patch depends on all previous patches to
work, so I want to sent it all in one go.

Hydrus is something I wanted to use and decided to package, but this sent me on a deep rabbit
hole of packaging new software and fixing what's already present. There are still problems with
swftools and hydrus that I couldn't resolve, but those are minor and I'll dedicate time to fixing
them in the future. I provided more details in relevant commit messages and source comments.



Tomasz Jeneralczyk (6):
  gnu: Add swftools.
  gnu: Add python-xvfbwrapper.
  gnu: Add python-mpv.
  gnu: Add opencv-with-python.
  gnu: Update python-cloudscraper.
  gnu: Add hydrus-network.

Subject: [PATCH 1/6] gnu: Add swftools.
Date: Wed, 27 Jul 2022 21:00:23 +0200

This package will built all of swftools' tools but one: PDF2SWF, so I
purposefuly commented it out of description.
Swftools includes the source tarball of an old version of xpdf and I have not
been successful in replacing it with the version distributed in guix. However
I believe the near-completeness of the package warrants a release.

Also updated copyright and used modules.

Subject: [PATCH 3/6] gnu: Add python-mpv.
Date: Wed, 27 Jul 2022 21:00:25 +0200

Author states that the license of the library is inherited from libmpv,
which can be either GPLv2 or LPGLv2.1. That's why the package's license is
set to be the same as mpv's.

One of the tests had to be disabled because it would neither fail or pass,
blocking all other tests from running and the package from finishing its build
process. I have no clue on why it happens.

Rarely some tests fail without any apparent reason. This is possibly related
to: https://github.com/jaseg/python-mpv/issues/209

Also add copyright.

Subject: [PATCH 6/6] gnu: Add hydrus-network.
Date: Wed, 27 Jul 2022 21:00:28 +0200

Hydrus-network has a weekly release cycle and is meant to be used from its own
directory so I artificially spread it out to comply with guix's expectations.

Three binaries from inputs are copied into a directory hydrus knows about:
  * ffmpeg - works as expected
  * swftools - does not do anything neither on guix or Arch linux - possibly
  an unfinished feature, but I left it in, in case it gets fixed in a future version.
  * miniupnpc - times out on my system, but it should work otherwise.

I was not able to build the program's help files. Updating
python-pymdown-extensions to its latest version might be the solution, but
this would require also packaging its new build system that is not present in
guix yet. I decided to cut short there.

Also adds copyright and new used modules.

* gnu/packages/image-viewers.scm (hydrus-network): Add variable.

IIUC, that's for using Guile modules defined in packages -- but mpv is 
not a Guile package, so I expect that the surrounding with-extensions 
can be dropped.

Look for substitute-keyword-arguments, which isn't stateful and hence 
there is less risk of accidentally modifying the arguments of the parent 
package.  Also, any reason for not adding this to the original package? 
(Possibly there is one).

Run "./pre-inst-env guix lint hydrus-network", it will have a remark 
about this.  Also, technically this is racy -- it's possible for python 
to start before Xvfb is ready though so far this doesn't seem to have 
caused trouble for other packages yet AFAIK -- I recommend "xvfb-run" 
"--" "python" "test.py" instead.

(I just scrolled quickly through the patches, a more full review will 
have to come later.)

Maxime.

This sounds like something upstream should be informed about, otherwise 
they wouldn't know there is something to fix.

You're right. I dropped it with no negative consequences.

I had a friend on arch linux run those tests and everything worked just 
fine, so it might have something to do with guix
itself or an incomplete package definition. In any case, I'll make sure 
to write a proper bug report in the upstream repo later.

Thanks, this macro is not documented in manual, but it looks much nicer 
now.
The reason I made a new package is simply because someone on irc 
recommended me to do as such. Though your question made me realize
that just adding one flag worked because all the necessary packages to 
build python buildings were in opencv package already...
maybe originally it was intended for the python bindings to be included 
in opencv? And so I added the flag to opencv and removed
my original package - it works all the same.

I though I missed something so I ran lint again, but it only said 
there's a new version of hydrus available.
Nevertheless I changed the invocation to what you recommended. I also 
updated hydrus to version 493.

Thank you for all your comments so far.
I made changes but I wont send them as patches until I fix all the 
problems or get a confirmation that there's nothing more to do.

However I'm attaching a "preview" diff of the changes I'll want to 
iclude in v2 of my patches.
I suppose I should only send v2 of the ones I changed, right?.

Perhaps these comments, or some of them, should go as comments in the
source?  That will prove helpful next time you or someone else tries to
work on the package.

This is unnecessary as (guix build utils) is always present on the build
side.

Nitpick: GNU and Guix convention is to use the term “path” to denote a
search path (like $PATH, etc.) and to use “file name” (or “file”) to
denote a file name, as is the case here.

In this case it might be enough to write ‘client’ instead of
‘client-path’, and similarly for ‘server-path’.

In general, the solution here, rather than copy files like the ‘ffmpeg’
executable, would be to patch Hydrus so that it contains the absolute
file name of ‘ffmpeg’ as returned by (search-input-file inputs "/bin/ffmpeg").

How does that sound?

Thanks,
Ludo’.

In addition, this substitution should be done in a phase rather than in
a snippet, because (1) the result of ‘guix build -S’ should be
platform-independent and thus not include the file name of ‘mpv’ for a
particular system, and (2) the reference to variable ‘mpv’ at the top
level can cause problems due to circular dependencies among modules.

For clarity, could you resent the whole series with those changes,
squashing the relevant amendments?

Thanks in advance,
Ludo’.

Looks like the linter ignored hydrus-network because it doesn't 
understand the 'let' construct ... work for later (not this patch 
series) ...

They cluttered the code with meta-information that I didn't consider to 
be directly related to the package's source. Thought anyone searching 
would see the commit message and that would be enough. I'll add them 
back in if that's what you prefer.

At the time I thought that directly patching the binary paths could 
break some logic, but I looked into it and it looks like I only had to 
patch one `if` statement. This could change in future releases, but it's 
not likely. It appears to work as well and maybe even better - Now 
miniupnpc isn't timing out for me, which might or might not be because 
of this change.

I didn't know that, but it makes sense. I moved the code into its own 
phase.
And if I understand the 2nd point correctly I should use something like 
`(assoc-ref inputs "mpv")` instead of `#$mpv`, right? I  cannot use 
`(search-input-file ...)` because the name of the mpv's lib is 
determined during runtime by the python code and I didn't want to 
hardcode the mpv so file's version.

After I finish making the changes I'll send the whole patchset again, it 
will also include updated packages to their newest release and be 
rebased onto current master.

Thank you for taking the time to review my work.

No, the assoc-ref style is basically deprecated last I heard. The problem
is with snippets: apparently something with the definition of the `snippet`
field can cause module dependency issues, whereas `arguments` does not
suffer from the same. IIRC, the issue is that the former is not specifie
as a `(delayed)` field. So, #$pkg is okay in arguments, but sometimes not
in snippets.

Does this mean I should replace `(assoc-ref inputs "python")` with 
`#$python` in the install phase of hydrus?
I checked and it didn't cause any problems.

I also noticed that python-mpv's mpv library cannot find libmpv.so 
during runtime (only in the check phase) so I hardcoded the path in 
source to `(search-input-file inputs "/lib/libmpv.so")`.
Was told on irc that most libraries are hardcoded so I take it's not a 
problem.

You could, but I think #$(this-package-input "python") would be better style.

Subject: [PATCH v2 1/6] gnu: Add swftools.
Date: Sun, 14 Aug 2022 14:46:18 +0200

This package will built all of swftools' tools but one: PDF2SWF, so I
purposefuly commented it out of description.
Swftools includes the source tarball of an old version of xpdf and I have not
been successful in replacing it with the version distributed in guix. However
I believe the near-completeness of the package warrants a release.

Also updated copyright and used modules.

Subject: [PATCH v2 3/6] gnu: Add python-mpv.
Date: Sun, 14 Aug 2022 14:46:20 +0200

Author states that the license of the library is inherited from libmpv,
which can be either GPLv2 or LPGLv2.1. That's why the package's license is
set to be the same as mpv's.

One of the tests had to be disabled because it would neither fail or pass,
blocking all other tests from running and the package from finishing its build
process. I have no clue on why it happens.

Rarely some tests fail without any apparent reason. This is possibly related
to: https://github.com/jaseg/python-mpv/issues/209

Also add copyright.

The package already had all dependencies needed for its python bindings, so
enabling python support was as easy as adding a flag. Which makes me think
this was the intention from the start.

Subject: [PATCH v2 6/6] gnu: Add hydrus-network.
Date: Sun, 14 Aug 2022 14:46:23 +0200

Hydrus-network has a weekly release cycle and is meant to be used from its own
directory so I artificially spread it out to comply with guix's expectations.

I was not able to build the program's help files. Fixing it would probably
mean packaging a whole new build system for guix - more info in source
comments.

Also adds copyright and new used modules.

* gnu/packages/image-viewers.scm (hydrus-network): Add variable.

I pushed the whole series:

  9b8507df11 gnu: Add hydrus-network.
  f82a8873d3 gnu: python-cloudscraper: Update to 1.2.60.
  5920196e47 gnu: opencv: Build Python bindings.
  619af9f307 gnu: Add python-mpv.
  e1ea628776 gnu: Add python-xvfbwrapper.
  05246c691b gnu: Add swftools.

I had to make a number of adjustments, such as tweaking commit logs,
moving info from the commit log to comments for swftools, changing the
swftools license to ‘gpl2+’ (because source file headers carry the “or
any later version” wording), avoiding “(package-license mpv)” as this
leads to a top-level circular dependency, and removing bundled binaries
from hydrus-network.

Thanks,
Ludo’.
