[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

hi there, folks: I'd really like to release 0.7.0 but I would like it to be at least a little bit tested before I do so. Could those of you with CVS trees check everything out and see if it performs as advertised? Deeper bugs than that will have to wait for the next release, but I'd at least like to know if it works for someone other than me. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] Lore to Sphinx Conversion Progress Report 6
by Kevin Horn July 11, 2010

July 11, 2010

It's been a while, I know you were all waiting with baited breath... First a few fixes: - Thanks to Tim Allen and Steve Steiner, several theme issues were fixed. This fixes a few minor display bugs and should make pages validate properly. - inline markup will now include child contents. This causes rst not to display properly in cases of "nested inline markup", but should make it easier to manually fix these places later - :download: links are now generated for non-rst files ending … [View More]in .py (most of the examples), as welll as .tac and .sql files - toc entries which end in a "/" character now have "index appended to them in the ReST output, which fixes a few issues where the built-Sphinx docs would end up with broken navigation links. A couple of issues were also fixed at the PyCon sprints: - <cite> tags are now handled...sort of. According to Glyph, these aren't really very important, so we just return the contents of the tag without any special markup. If we feel the need to put citation markup back into the docs we can do that post-transition. - Glyph also found an easy way to improve the CSS of the theme somewhat. The issue where the sidebar drops below the main content should now be less of a problem, though it's not gone entirely. - Glyph and I also discussed a few different ways to handle links to the API docs and agreed on a way forward. Basically, well change the <code class='API'> tags into something like: :api:`path.to.documented object <label>`, and then create a docutils extension to convert that into a link. The beginnings of this are in the hg repos, but it looks like it won't be quite as simple as we thought. First, the way pydoctor generates links is deceptively simple. If you look up a module, like "twisted.internet.defer", the link looks like this: http://twistedmatrix.com/documents/9.0.0/api/twisted.internet.defer.html If you look up a class, like "twisted.internet.defer.Deferred" for example, the link looks like this: http://twistedmatrix.com/documents/current/api/twisted.internet.defer.Defer… Pretty simple right? But if you look up a function or method like "twisted.internet.defer.Deferred.callback", the link has an anchor, like so: http://twistedmatrix.com/documents/9.0.0/api/twisted.internet.defer.Deferre… So we'll need to do some checking on either the api docs or on twisted itself to determine what sort of object is being linked to. Shouldn't be super-difficult, just haven't had time yet. Second, I haven't yet figured out how to access the Sphinx config object from a docutils role function. I'm sure this is just a matter of finding an example or getting an answer from the mailing list, but I just haven't gotten to it yet. I think the API links are the only major issue still remaining until we start doing the conversion, so once this issue is handled, I'll probably file a ticket and create a branch in SVN for the conversion. If anyone has any docs tickets open, now is the time to get them fixed! And if anyone has some great ideas about how to organize the new docs in the repository, I'd love to hear them. As always, converted docs are here: http://twistedsphinx.funsize.net/ The lore2Sphinx Hg repos is here: http://bitbucket.org/khorn/lore2sphinx/ Comments, ideas, patches and pull requests gratefully accepted (or at least discussed).

I have recently started a project using Twisted with a MySQL backend.

At this point, I am using SQLAlchemy's SQL builder functionality (but not ORM layer) and using sAsync to manage the threading. Does anyone have experience with this technique … [View More]
