gramps: add python25 and python26 variants, move spell checking to spell variant, add graphviz variant, add dependencies

[lkraider (Paul Eipper)]

This patch adds python2.6 support to building Gramps.

Also gramps sould depend on libsoup, since otherwise it builds its own version, which may trigger bug #23467 .

[lkraider (Paul Eipper)]

just noting it fixes #23766 (libsoup dep) if applied

PS: forgot to add the maitainer again, sorry

[ryandesign (Ryan Carsten Schmidt)]

Using python26 is a good idea. For now I've switched gramps to unconditionally use python26 in r65611. Or is there a compelling reason why someone would still want the option of using python25?

I don't think we need to break spell checking support out into a variant.

The libsoup issue is filed as #23766. More info is requested there.

I see you also added a dependency on librsvg. What's that used for?

You also added a variant for graphviz. I suppose we could add that. It doesn't do a lot of course; gramps will be able to use graphviz at runtime if it's there, and won't if it's not. Or does gramps check for graphviz at build time? I didn't see any output indicating it did.

[lkraider (Paul Eipper)]

Personally I don't have any problems on it depending on python26 only, but it should be pointed out that Gramps works with python25, so others might find it useful to have that option.

I broke spelling into a variant since I don't need English spelling correction for a family tree app and also prefer to keep dependencies to a minimum, but sure, it's not really required.

Good question about librsvg. I added it because their HowTo page lists it as a dependency, I didn't really check the source though: ​http://www.gramps-project.org/wiki/index.php?title=Installation#Installing_GRAMPS_from_source_code

Graphviz is also listed there. I'm not sure it's a build dependency, even so, I prefer to have explicit dependencies also for runtime ones, since then I can know what a program is able to use feature-wise which I would otherwise never find out.

[lkraider (Paul Eipper)]

Note: graphviz port is depends_run only

[lkraider (Paul Eipper)]

I just dropped py26-gnome and gnome-python26-extras dependencies and the build worked fine for Gramps 3.2.0

[guy.linton@…]

The problem about changing to Python26 is that Gramps should have a dependency on webkit-gtk (in order to make the "Geographic View" available - this is in some sense optional, because the rest of Gramps works without it). I did not include this because webkit-gtk does not build for me. However, once this does build, it will need the python binding, and only py25-webkitgtk is available, there is no corresponding component for python26.

[guy.linton@…]

Unfortunately, Gramps does not run for me on python 2.6, I get:

4969: ERROR: gramps.py: line 138: Unhandled exception

ImportError: No module named _bsddb

Help please, I have no idea where python expects to find bsddb, nor why it is found in python25. I ran python_select python26, is there anything else I need to do to switch to python 26.

Directory /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/ does not have a _bsddb.so file - is this the problem?

[guy.linton@…]

I have copied the portfile for 3.2.0 (Version 0 using Python25) ​Revision 65604 from #24258 into my MacPorts sources tree and rebuilt, and am happy to say that my Gramps now works again.

I think that perhaps bdsdb for python26 is in bsddb185.so instead of _bsddb.so. But in my build, it does not seem to be complete. The last bit of otool -TMvDlL for python25 _bsddb.so says:

but for python26, the last part of the otool output is:

I have looked for similar issues, and perhaps #15099 is relevant since it seems to relate to where the libraries are, but I don't know how it relates to this problem.

Please let me know what flags for otool are needed if you want the rest of the otool output.

I added py26-webkitgtk in r65775.

Cc Me!

[guy.linton@…]

I have raised #24310 on python26 not providing bsddb.

So my vote would be to revert r65611, at least until #24310 is fixed, but I do appreciate that python26 works for some people.

[guy.linton@…]

Please see #24310.

I have now rebuilt python26 after installing the updated Xcode 25. Gramps now runs with python26, but I can't open a python26 database with python25 or vice-versa.

In addition, the python26 database is much slower (12 sec for 500 people with python25 and 9 mins 30 secs with python26).

lkraider, are your databases portable between Gramps based on Python25 and Gramps based on Python26, and have you noticed the slow-down? (What OS and architecture are you on, in case that makes a difference).

Hence I am not sure that we can say that python26 works (at least not very well)!

[lkraider (Paul Eipper)]

@guy.linton:

I didn't have speed issues here, although I have not used Gramps with Python 2.5, but I certainly didn't wait more than 1 min loading a database, even importing from a large GEDCOM one like this for example: ​http://www.genealogyforum.com/gedcom/gedcom1/ged3.htm

As I said, I didn't test it with Python 2.5, since I use only Python 2.6 on my system, so I don't know about interoperability of the database.

I did have problems generating the ancestry tree, with incomplete redrawing of the graph. It might be some version/compilation setting but I didn't debug it further since I'm not using that feature ATM.

[dbevans (David B. Evans)]

I believe this ticket is outdated. Latest version of gramps is 3.3.1 as of r84948.

Please test against this latest version and file a new ticket if any issues remain. Thanks.
