CppDB 0.0.2 Released
New Features:
- Performance optimizations in connection opening when using pool.
- Added advanced MySQL options support, patch from Krzysztof (kyku)
Bugs:
- Fixed crash on process shutdown when connections pool is used. The crash was caused by incorrect order of unloading the driver and closing shared object.
- Added missing copy constructor.
- Fixed error reporting in PostgreSQL backend when statement preparation fails.
CppCMS 0.99.5 released
Changelog:
New Features:
New XSS Filer. It is very new and experimental feature. It allows to validate and filter the HTML input that comes from untrusted source to ensure that it does not include malicious code. This is very common case when we want to integrate in the applications tools like TinyMCS.
It is based on white-list of tags and HTML attributes values that are allowed to be included.
The filter and filtering rules can be found under cppcms::xss namespace.
Currently XSS filter is used only on CppCMS's wiki. So you are welcome to try to bypass it editing the wiki's Sandbox and if you succeed please report me immediately.
Support Windows Vista/Windows 7 API. It allows to build CppCMS on Windows without pthreads-win32 library.
Note: you need to use CMake's option:
-DUSE_WINDOWS6_API=ONas by default CppCMS targeted for Windows XP and above.Changed default number of worker threads to depend on number of physical CPUs
Bugs Fixes:
- Fixed incorrect mutex configuration that caused deadlocks in preforking mode
- Some fixed in CMake scripts that caused libraries not being found in some situations.
- Some fixes to allow CppCMS to work with uclibc
- Fixed problem in URL dispatching to sub application that caused inability to redefine main function of them
- Some bug fixes in response handling
SQL Connectivity Libraries released
Today two SQL Connectivity libraries were released.
- Released first version 0.0.1 of CppDB library - new powerful SQL Connectivity library written in C++.
Released updated version 0.0.4 of DbiXX - libdbi wrapper. It was also deprecated in favor of CppDB.
It would be continued to be updated with bug fixed and probably small features, but the support will be discontinued withing a year or two, depending on the users needs.
Downloads are available in usual place: https://sourceforge.net/projects/cppcms/files/
Documentation can be found at: http://art-blog.no-ip.info/sql
Why CppDB? What is New There?
New SQL Connectivity library was introduced. There were many reasons for this step:
- Support of both prepared and unprepared statements and transparent prepared statements caching.
- Connection Pooling
- Static and Dynamic linking of the modules - very important for deploy.
- Native windows support including MSVC compiler.
- Removal of additional intermediate layer between the C++ code and native SQL client - libdbi.
- Performance.
- Ensure thread safety (which libdbi was lacking on some platforms - windows)
What is new in DbiXX
- Correct overloading for all integer types
- Access to underlying dbi data structures from all classes
- Support of connection string
- Support of getting driver name (for conditional coding)
- Full Doxygen documentation
- Some code cleanup - to make it locale safe
Why not other libraries like SOCI or QtSql
- QtSql is very heavy depends on Qt framework and does not fit well to modern C++ design (as it provides their own classes for everything - QString etc)
- SOCI - the development cycle is very slow, the quality of some primary FOSS RDBMS drivers is very low, and general disagreement about several concepts.
CppCMS 0.99.4 released
New Features:
- Added support of OpenSSL as alternative to Gcrypt library for AES cookies encryption
- Added support of strength options of AES and better selection of hash for HMAC.
- Added support of recording and showing stack backtrace from thrown exceptions - for better debug-ability of the code.
- Added support of daemonization - running as service under Unix, including options: switch to unprivileged user and
chrooting to specified directory. - Added support of reset_session function in session_interface that forces allocation of new session id - to be used for preventing session fixation.
- Added support of suppression of error messages by default - the exception information is not shown by default to user.
- Improved session ids generation security.
- Improved performance of generation of random numbers under Windows
- Improved Content-Type header handling
Bug Fixes:
- Fixed accidental crashes caused by dangling reference.
- Fixed bug incorrect using of non-blocking sockets caused incomplete writes on long outputs
- Fixed memory leak in AES encryption backend
- Fixed incorrect handing of script name in HTTP server.
- Fixed incorrect shutdown handling when working in prefork mode caused deadlock between parent and child on exit.
- Fixed bug in booster::streambuf caused accidental character loss, added handing of putback.
- Fixed incorrect error handing in http_response class that could cause thread-pool to run out of threads.
- Various platform related test fixes

CppCMS Nightly Tests
Hello All,
In order to simplify CppCMS release procedure and ensure that current SVN trunk it not got broken on platforms that are used less frequently the night build and test were set up.
Each night svn-trunk is tested with different compilers and platforms. The full test matrix in not complete yet, but most important platforms and compilers are tested (or actually the plafroms that can be tested relatievly easily)
It is expected to be extedned more in future.
Thanks to VirtualBox for simple and convinient virtualization solutions.
