Bindings for Python or Ruby? And APR docco?

[Rodent of Unusual Size <ke...@gmail.com>]

Please be gentle, I haven't been around APR for quite a few years..

I'm tentatively interested in a multi-language application that could
benefit from APR, specifically things like semaphores and shared memory.

Are there any OSS binding libraries making *any* APR functionality
available to Python (primarily) or Ruby?  Either from the APR project
itself, or provided by some other person or organisation?

For that matter, are there any good *BOOKS* about APR out there?  I've
found the documentation, apparently built from code-embedded comments, to
be a bit .. sparse.  I might be interested in improving that, if someone
would be willing to inform me (and possibly hold my hand for a bit 😁)
about the process for doing so..

's been a very, _very_ long time since I was involved with APR, so I'm
going to have to feel my way back into being able to provide any value.
With all the various different ways ASF projects have now of handling
submissions, issues, and code repos, I'm sure my SVN-and-email 'muscle
memory' is stale and obsolete..

Thanks!

Yeah, saw ... was explaining why such bindings would not exist.

APR is still svn-based so sending patches to the list is fine. An issue
works too, but feels heavier for everybody. The repos/asf/apr/ area is
committers-only.

I mentioned a multi-language (single- or multi-process) environment; for
example, some apps running C and some running Python on a Raspberry Pi.  If
it were a single-language situation, naturally I'd use the native
mechanisms.  And right now I'm thinking about the IPC functionality, not
the memory management bits (which, admittedly, I expect are a very big part
of APR's usage profiles).

So what's the process for enhancing docco in the code?  Is it through
GitHub pull requests, patches submitted to BZ/Jira, just commit to the dev
branch (assuming CTR)?  In re-engaging with ASF, I'm finding the
github-RW/github-RO-mirror/svn per-project setup a bit difficult to track
and remember..

Thanks!

Thanks for the mention, but I doubt that would tell RoUS anything he doesn't
already know!  Bindings for scripting languages get mentioned only in passing
in the book, and the detail goes no deeper than "mod_foo has foo bindings for
HTTPD API and APR so you can do much the same things in foo as in C".

I don't think APR would make much of a book on its own.  Sure, you could
expand on what I wrote, but only up to a point, so you'd want some context
for it.  Scripting might make just such a context if you can make a case that
APR adds value to existing scripting language libraries other than in a
specific context like HTTPD.

There's a 30 page chapter on APR in Nick Kew's The Apache Modules Book.

There are no bindings that I'm aware of. I don't think APR would add much
value to Python, which has its own semaphores and memory mapping. Python's
reference counting and garbage collection handle the memory management that
APR pools would be used for.

While I would doubt there is a book about APR itself, I would bet any book
that talks about writing a module for Apache has extensive coverage of APR
(if such a book exists; dunno). There is no docco besides the headers and
the code itself.
