Hi Ertugrul, Looks like some interesting projects. For TLS/SSL support, I would look into Vincent Hanquez's tls package[1]. Michael [1] http://hackage.haskell.org/package/tls On Sun, Apr 3, 2011 at 11:09 PM, Ertugrul Soeylemez wrote:

Hello fellow Haskellers,

(once again posted to the cafe, because the Haskell mailing list rejects my mails.)

I have released quite a few libraries over time on Hackage. I feel they are stable enough now to announce them here.

* contstuff: Fast and flexible monad transformers based on the CPS concept. Mainly it helps getting rid of large transformer stacks, because it unifies some monad transformers (like StateT and ContT), and it is also faster than the naive approach.

This library is comparable to a combination of the transformers package with Edward Kmett's monad-ran package, but without hiding the CPS transformation. In early benchmarks ChoiceT turned out to be twice as fast as normal Haskell lists, and it is also a proper list monad transformer.

Finally in the Control.ContStuff.Classes module you find lots of useful utility classes, which seem to be unique to contstuff.

* dnscache: Handy DNS caching library. This library automatically manages a set of resolver threads for you, which share a reply cache. This allows very fast mass-resolution.

The library also comes with a handy command line utility called 'massdns' for quick resolution of even very large lists of entities. Call massdns without arguments to get usage help.

* ihttp: This is an HTTP library based on enumerators giving you maximum flexibility and control over the connection. Using proper iteratees you can simply implement e.g. proxy clients (my main use case), but also HTTP servers. Using proper enumeratees you can also encapsulate the connection in an SSL/TLS layer, but unfortunately there doesn't seem to be such an SSL/TLS implementation yet.

* ismtp: This is an advanced ESMTP library, which allows you to structure your sessions as you like. It also features an automated resolver for MX records using the dnscache library. Right now there is support for most of the base functionalities of the protocol as specified in RFC 821 (SMTP) and RFC 1425 (service extensions).

An update to RFC 2821 is planned, but is not necessary for practical purposes. The new RFC mainly removes some unneeded features and unifies the two mentioned RFCs.

Right now there is no support for SMTL (SASL) authentication, but it is planned for a near future release. For the time being you can implement your own iteratees for this purpose, if you depend on authentication.

* netlines: This is a library for writing implementations of text-based protocols. In particular it allows reading lines safely from untrusted sources with a maximum length in constant space.

* yesod-tableview: For web applications using Michael Snoyman's Yesod web framework this library implements an easy to use table renderer mainly for database records. It is in an early stage of development right now, but as the need arises, I will extend it.

To use the networking libraries, you should be familiar with John Millikin's 'enumerator' package. If you're not, I recommend studying it, because it is a useful library for all kinds of stream processing like network connections, files and concurrent channels.

All mentioned libraries have been tested extensively for correctness and safety. Especially the networking libraries have undergone a lot of penetration testing. However, I'm only one developer, so I would be glad to hear about any vulnerabilities and other shortcomings you find. Usually I have a very short response time to bugs in these libraries, so please don't hesitate to contact me. Feature requests are also welcome, of course. =)

Please note that major version numbers specify interface versions in my libraries. In other words, a new major version of a package usually means that the API has changed in a way, which is likely to break dependent packages.

I would like to use this opportunity to thank a few people in particular (alphabetically):

- Cale Gibbard, - Edward Kmett, - John Millikin, - Bryan O'Sullivan and - Michael Snoyman.

I appreciate your efforts both in libraries and support. Many thanks, guys! Thanks also to the rest of the innovative and helpful Haskell community.

Greets, Ertugrul
