gdal 3.5.0: missing doc/ in dist tar ball?

Trying to update my gdal rpm package I found that acter pass autoconf I cannot do make man

the man pages are already generated in the tar ball. The "man" target only works in a git checkout, since the tar ball doesn't include the doc/ subdirectory.

May 22 '22 21:05 rouault

Looks like the similar is with docs target

+ /usr/bin/make -O -j48 V=1 VERBOSE=1 docs -j1
(cd doc; make html)
/bin/sh: line 1: cd: doc: No such file or directory
make[1]: Entering directory '/home/tkloczko/rpmbuild/BUILD/gdal-3.5.0'
make[1]: *** No rule to make target 'html'.  Stop.
make[1]: Leaving directory '/home/tkloczko/rpmbuild/BUILD/gdal-3.5.0'

May 24 '22 09:05 kloczek

did you actually build the HTML docs ? Debian had stopped building them because that required Sphinx, etc. That was also removed from the tarball because the CMake target for docs were not working (cf https://github.com/OSGeo/gdal/issues/5483). But perhaps we might revisit that for 3.6.0 if there's interest to build the HTML docs from tarballs.

May 24 '22 09:05 rouault

As long as docs directory is no no longer part of the dist tar ball I've disabled add that documentation to final packages.

May 24 '22 11:05 kloczek

OK so how to build documentation now? 🤔

May 24 '22 11:05 kloczek

I've uploaded in https://download.osgeo.org/gdal/3.5.0/gdal-3.5.0-doc-src.tar.gz the content of the doc/ subdirectory. So if you untar alongside the main archive, you should be able to build docs.

May 24 '22 12:05 rouault

If documentation is handled now by sphinx to be honest I would be more interested generate man pages. So question still remains .. how to build now devel documentation? 😄

May 24 '22 12:05 kloczek

If documentation is handled now by sphinx

"now": it has been like this for years

I would be more interested generate man pages.

as I said, the tarball include them already generated. "make install" will install them

how to build now devel documentation?

What I mentioned in above comment. untar gdal-3.5.0-doc-src.tar.gz, alongside main gdal-3.5.0.tar.gz, so that the doc/ subdirectory is added, and run "make docs" (assuming you have the prerequisites of doc/requirements.txt)

May 24 '22 12:05 rouault

Hmm .. but why all that is not in single source tar ball? 🤔 Probability that someone will be building gdal without documentation IMO is close to 0.

May 24 '22 13:05 kloczek

why all that is not in single source tar ball?

The removal of the doc/ subdirectory in the tarball was probably a confusion of mine (I had the feeling that we didn't package it before, when we moved the content of gdal/* to top directory of the git repository, but I was wrong as it was present in the 3.4.x tarball). But actually, I'm no sure it is a wrong move, as it also helps making the main tarball smaller

Probability that someone will be building gdal without documentation IMO is close to 0.

I would have said the contrary from the overall feedback we got until here. Packagers from which we get regular feedback seem to have stopped building the docs since we switched to Sphinx, and most people just rely on the pregenerated HTML doc in the http://download.osgeo.org/gdal/3.5.0/gdal350doc.zip archive, or on https://gdal.org. And for man pages, "make install" does the job with the pregenerated man pages.

Hmm looking on content of the gdal-3.5.0-doc-src.tar.gz found quite complicated cmak files. Looks like all of that can be dropped if doc/source/conf.py is well written whole documentation in desired format shuld be possible to build using single command like

sphinx-build -n -T -b man doc/source build/sphinx/man

I have more and more impression that by splitting source tree to different tar balls and adding own cmake files you are overcomplicating everything 🤔 I would rather give chance to build gdal from autogenerated from git tag tar ball https://github.com/OSGeo/gdal/archive/refs/tags/v3.5.0.tar.gz If it will be working additionally will have 100% guarantee that I would be able use any git commit added after release so in case any JFDI fixes it will be easier to integrate everything with post release fixes.

May 24 '22 13:05 kloczek

Instead wasting time on complicating release process, splitting source code, uploading somewhere dist tar balls etc. I would recommend focus on maxim reuse autogenerated tar balls from tags. Tagging can be additionally signed. You can read about how to do that on https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-tags

May 24 '22 13:05 kloczek

found quite complicated cmake files.

The CMakeLists.txt for doc/ are not ready (was one of the reason to remove doc/ from the tarball if I remember correctly). And even once fixed, it would likely be intended to be used as part of the main build, not standalone.

Instead wasting time on complicating release process

Please be gentle with us. We spent huge efforts adding the CMake build system, and the transition period with autoconf + CMake is complicated to handle.

instead of splitting source code

We have always split the tarballs for (source + doc) from the one from autotests. Regarding doc, I'm not sure what to do, as there's no consensus on how to handle that.

The Debian package removed the doc directory since 3.1.0-rc1 because license and copyright review is a PITA with the inclusion of the RTD fork. The libgdal-doc package wasn't very popular, so not a big loss for users, the online documentation suits most users just fine.

If you guys forcing me to update build procedure almost every release because you have some brilliant idea .. sorry please stick to KISS principle and be on the distance from BecauseWeCan™️ Sorry for maybe bitter words but sticking to "Don't move, improve" and KISS may have more real value.

The Debian package removed the doc directory since 3.1.0-rc1 because license and copyright review is a PITA with the inclusion of the RTD fork.

So .. why not start distribute everything under one common licence or set of licences to make packagers life easier? 🤔

If you really want to move away from GNU auto tools please move to meson. This only build framework which provides interface which can be easily plugged into complicated packages set population system because it provides something like that

So .. why not start distribute everything under one common licence or set of licences to make packagers life easier?

I'm not sure what the licensing issue is really. The license of read-the-docs is MIT (https://github.com/readthedocs/readthedocs.org/blob/main/LICENSE), and the fork of it we inherited to is also MIT: https://github.com/OSGeo/gdal/blob/master/doc/source/gdal_rtd/LICENSE

If you really want to move away from GNU auto tools please move to meson.

The move to CMake was discussed and approved many months ago: https://gdal.org/development/rfc/rfc84_cmake.html . We're not going to change from build system in the next 10 years hopefully.

This was e specially hard to prepare as that block using CC=<static_code_analyser_or_autitin_tool> make which do not recognise many gcc warning options. If you need to have proper view of some compile time warnings please use only on CI something like "CFLAGS="-Wfoo -Wbar "./configure ` instead hardcoding all that crap straight into the code which other people may find as completely useless. That approach would allow make build procedure much ready for use case which you may have no idea that other people are using on daily baseses.

Please let me know if you want any of those patches as PRs.

I would have said the contrary from the overall feedback we got until here. Packagers from which we get regular feedback seem to have stopped building the docs since we switched to Sphinx, and most people just rely on the pregenerated HTML doc in the http://download.osgeo.org/gdal/3.5.0/gdal350doc.zip archive, or on https://gdal.org. And for man pages, "make install" does the job with the pregenerated man pages.

Thanks for pointing to the pregenerated HTML doc archive (for MS4W I still build & package Sphinx docs, but this pregenerated archive is so much easier, thanks!). I didn't realize this existed, thanks for this, very nice addition.

May 24 '22 14:05 jmckenna

So .. why not start distribute everything under one common licence or set of licences to make packagers life easier?

I'm not sure what the licensing issue is really. The license of read-the-docs is MIT (https://github.com/readthedocs/readthedocs.org/blob/main/LICENSE), and the fork of it we inherited to is also MIT: https://github.com/OSGeo/gdal/blob/master/doc/source/gdal_rtd/LICENSE

The fonts are differently licensed, e.g. miriamlibre, sintony, and sourcecodepro are OFL-1.1, but proximanova is complicated.

May 24 '22 14:05 sebastic

just checked what I have in my set of patches against gdal:

The patches against .c files are no longer needed with GDAL 3.5.0/master as far as I can see, and we no longer maintain older branches. The ones in autoconf/GNUmakefile are not going to be useful as we're going to remove it in master in a few weeks

instead hardcoding all that crap

please soften your language. That "crap" is extremely useful for developers on a daily basis. If that causes issues for specific builds/purposes, then I guess a specific option could be added to disable them. That should be done for CMake builds, and the equivalent is in gdal.cmake

May 24 '22 14:05 rouault

but proximanova is complicated.

I suppose we could switch to another font if that one is an issue. But should be a topic for another ticket, as that one becomes messy

May 24 '22 14:05 rouault

And yet another though. Most of the compile or link time issue would be way easier to avoid if from the beginning GNU tooling would be used with proper automake use. It means replace all GNUmakefile files with way simpler Makefile.am. Trying o move from raw autoconf + custom GNUmakefile files to cmake is like tiring to escape from fry pan to open fire .. all because you need to learn from the begging the same tricks using completely new tooling. Just in case .. I'm not complaining. I have my own solutions. I'm only trying gently point that sometimes it was really better to follow evolution instead introducing revolution.

May 24 '22 14:05 kloczek

I'm only trying gently point that sometimes it was really better to follow evolution instead introducing revolution.

The main motivation behind the switch to CMake was to have a single build system for Unix and Windows. Proper use of autoconf/automake wouldn't have solved that. A number of projects related to GDAL (PROJ, GEOS) have gone through that route.

I suppose we could switch to another font if that one is an issue. But should be a topic for another ticket, as that one becomes messy

Sorry for that. I've lost a bit my temper .. only because I've realised that at every new release I've spend significant amount of time only to make build procedure working .. again.

And again .. IMO cmake it is kind of dead end. It looks attractive but provides nothing new compare to GNU auto tools which is now problematic only because it it poorly maintained. Someone instead reinventing the wheel should just make a fork and start fixing normal flow of new issues. At least autoconf now is ell enough maintained however to make that more robust automake and libtool needs to be maintained on the same level as autoconf.

The same can be done with GNU auto tools and meson. Problem with GNU auto tools is that because begging of that framework was on Unix systems there is no to many people which knows how to correctly use it with Windows. So it is not that that tooling was or is not ready for Windows learning that tooling for Windows developers is quite hard because there is no enough critical mass people which now how to use it on that platform.

And building stuff would be easy if custom GNUmakefile files where used. That was main obstacle ..

So .. why not start distribute everything under one common licence or set of licences to make packagers life easier?

I'm not sure what the licensing issue is really. The license of read-the-docs is MIT (https://github.com/readthedocs/readthedocs.org/blob/main/LICENSE), and the fork of it we inherited to is also MIT: https://github.com/OSGeo/gdal/blob/master/doc/source/gdal_rtd/LICENSE

So .. there is no issue -> no real reason to keep documentation separated.😄

BTW: that RFC.

SWIG bindings[](https://gdal.org/development/rfc/rfc84_cmake.html#swig-bindings)
The Python, Java and CSharp bindings will be available as options of the CMake build options.

Please do net keep to many eggs in one basket. python binding can be maintained as separated pypi project, perl on cpan, java .. If you are going to keep everything under one cmake hood please be aware that cmake do not support pep517 build procedure and looks like no one want to maintain that part of the cmake. All because python has its own build tooling. The same will be true with per, java, WhateverOtherLanguageBinding.

If you really want to move away from GNU auto tools please move to meson.

The move to CMake was discussed and approved many months ago: https://gdal.org/development/rfc/rfc84_cmake.html . We're not going to change from build system in the next 10 years hopefully.

If you know what will happen within next 10ys please start playing lottery 😋

10 years ago not to many people would tell you that GNU autotools is crappy 😄

I hope it's still ok to be on-topic with this ticket :-)

pkgsrc has not been packaging docs so I didn't notice the withdrawal.

pkgsrc doesn't end up with man pages. That's a bug. I am still using autoconf (because 3.4 did, and I haven't gotten to changing the package, which I view as something I need to do before I update to 3.6).

In general, I think people should be able to get sources for docs and build them, even if there are pregenerated files. I am fine with the release process having gdal-docs-src next to gdal as a tarball, assuming once can treat that like a normal package and build docs with configure/make/make install (in 3.5) or "mkdir build; cd build; cmake .." (in 3.5 and 3.6+). I am also totally fine with a docs dir in the main tarball, where one builds it by "cd docs" and then one of the above. That avoids split versioning and an extra file, with a an extra cd. In general I like things that are splittable being split rather than build options, so we can straightforwardly build just gdal code (and install man pages) in one package and then have docs with doc dependencies with another. Unlike Debian with split packages AIUI, in pkgsrc it's not ok to make the main build depend on the union of dependencies, as we few users building from source, including on low-resource machines, as normal.

please soften your language. That "crap" is extremely useful for developers on a daily basis. If that causes issues for specific builds/purposes, then I guess a specific option could be added to disable them. That should be done for CMake builds, and the equivalent is in gdal.cmake

In general, it's considered a code smell for -Werror to be embedded inside a build system, whether that is done in autotools, cmake, or meson is pretty irrelevant.

As a developer tool and for enforcing CI checks, I agree it's extremely useful. The problem really is when ordinary distributors get -Werror in stable release builds, as that can lead to "the distro updated the compiler, GCC added new default warnings, now unrelated packages fail during the mass rebuilds for poppler or perl or whatever". Stable release packages failing in mass rebuilds is a bit of a painful experience, though hopefully one we can all remain calm about.

So, options (and best of all, standardized options) are the best of both worlds IMO.

Meson does include a builtin core option meson setup -Dwerror=true to toggle it on/off, which is useful as a convention (so people don't need to go hunting down options per software project) but of course an option can be manually added in cmake too.

It is... probably not remotely worth porting the entire project from cmake to Meson just to take advantage of Meson's builtin werror configure option, especially if you've already considered it and rejected it because despite meson generally scoring well on the same list of requirements, it simply wasn't familiar to active contributors, and that's pretty important too...

Problem with GNU auto tools is that because begging of that framework was on Unix systems there is no to many people which knows how to correctly use it with Windows. So it is not that that tooling was or is not ready for Windows learning that tooling for Windows developers is quite hard because there is no enough critical mass people which now how to use it on that platform.

The problem is also that autotools on Windows basically requires building from a mingw/msys/cygwin shell after installing a ton of stuff just to appease autotools, and it's a significantly awkward experience, really slow because shell script build systems rely heavily on forking which has steep penalties on Windows, etc. So while it's technically possible, in practice the Windows world is divided into two groups:

those who used msys2 anyway and aren't bothered
those who rebel and use cmake or meson even if they have to fork it themselves, which apparently happened here as there were multiple parties that maintained their own cmake build for gdal
