POCO Sponsorship

Filed under: News by alex at 19:07

Recently, we’ve received inquiries about sponsoring the POCO project. Aside from corporate (Gold, Silver, Bronze) type sponsorships which come with commercial-grade support, small individual contributions are very welcome and encouraged. Please look for the PayPal link at the bottom of the Sponsorship page or contribute directly from here:

Thanks to all who have contributed so far and will do so in the future!

POCO is on the Move

Filed under: News by alex at 03:15

After many months of absence and low-level involvement with the project (for personal and professional reasons), I am back. We also have commitment from two other community members (Marian Krivos and Franky Braem) to help significantly with the project. For starters, Marian has retired old and I have just committed brand new trunk code. For the time being, it was only built on Windows, but we’ll have other builds ready within the next week or two.

Most significant new features are:

  • DynamicAny (now known as Poco::Dynamic::Var, although Poco::DynamicAny will still work) improvements
  • Poco::Data improvements (DateTime support, bulk operations, SessionPool, Transaction support, async SQL execution, in-memory SQLite … warning, though – we broke old Poco::Data code!)
  • Poco::PDF library
  • Poco::JSON library and Poco::Util::JSONConfiguration (not in the trunk yet, will be soon)
  • VS project generator
  • PocoDoc generator

And many more other improvements. This code is base for 1.5 release, which we are targeting for mid-September Aug 27 July 4 30 (to steal the fireworks thunder ;-) ). At the same time, we are actively working with C++ Standards Committee on the proposal for inclusion of POCO into the C++ standard. Yes, async I/O is on our TODO list. I won’t promise it for 1.5, though, unless I get a committed contributor willing to write it.

Which brings me to the “last but not least”: we need contributors (library or build/test system owners/maintainers in particular) and sponsors. If you are benefiting from POCO, please consider helping in any way you can. This can be by contributing code, owning a library or other concern (build system, tests, samples, platform, OS installation packages …), providing CI server space, sponsoring, etc.

Let’s join forces and give POCO the boost (no pun intended) it deserves.

EDIT (Oct 15 2012): little bit more than 3 months late, we have POCO 1.5.0. Thanks to everyone who helped with this release.

Coming to Silicon Valley

Filed under: Uncategorized by guenter at 22:05

I will be in Silicon Valley this summer (July 3 to September 26) and I’m looking to rent a furnished one-bedroom apartment in or near Sunnyvale. If you know or can recommend a place for me and my family to stay at please let me know (guenter at appinf.com). I’ll have an office in the Plug & Play Tech Center in Sunnyvale, so anything within about 30 minutes of driving distance would be great. Looking forward to spend this summer in California and to meeting all you POCO users in Silicon Valley!

1.4.3p1 Available – Important patch for Windows XP 32-bit

Filed under: News by guenter at 16:27

An important patch for the 1.4.3 release is available. In 1.4.3, Poco::Util::WinRegistryKey used a function (RegDeleteKeyEx) not available on Windows XP 32-bit (it is available starting with WinXP 64-bit SP3). This prevented applications using WinRegistryKey (or ServerApplication, which uses this class) from running on Windows XP. Bug report is here.
This has been fixed in 1.4.3p1, which has just been released. Along with this issue, we have also fixed a testsuite failure in the Foundation testsuite and two potential warnings in the WebSocket sources. Upgrading is recommended for everyone using POCO on Windows. There is no need to re-download the entire release. A patched Util/src/WinRegistryKey.cpp file has been attached to the bug report.

Release 1.4.3 is Available

Filed under: News by guenter at 16:08

Release 1.4.3 of the POCO C++ Libraries is now available. This release contains new features and various improvements and bugfixes. Notable new features are support for HTTP Digest authentication (contributed by Anton V. Yabchinskiy) and WebSockets (RFC 6455). As always, the CHANGELOG has all the details. Upgrading is recommended for all users of previous releases.

Introducing my-devices.net

Filed under: News by guenter at 19:21

We are proud to introduce our latest product, built with POCO: my-devices.net.
my-devices.net is a web and cloud-based platform enabling secure remote access to the built-in web server of smart devices such as industrial automation systems, smart home devices, monitoring and control systems for heating, solarthermal or photovoltaic plants, and similar systems. With my-devices.net, any device with a built-in web server can be securely accessed remotely over the internet using any web browser running on a PC, smartphone or tablet. This even works if the device is behind a NAT router, firewall or proxy server.
For more information, please visit my-devices.net. If you want to try out the system with your own device, please let us know!

Merry Christmas and a Happy New Year!

POCO C++ Libraries Patch Release 1.4.2p1 Available

Filed under: News by guenter at 17:53

This release fixes issues for some users caused by a change to Poco::SharedLibrary (use of RTLD_DEEPBIND on Linux). This change has been reverted. Instead, overloads to load() and the constructor are provided that allow flags being passed to the loader. One of the flags currently supported in SHLIB_LOCAL, resulting in dlopen() being called with RTLD_LOCAL instead of RTLD_GLOBAL, which is the default. Another bug has been fixed as well. As always, the CHANGELOG has the details. Upgrading is recommended for all users using Poco::SharedLibrary or Poco::ClassLoader.
