CentOS and apache

A great part of VPS users run a CentOS, also a lot of real servers run CentOS nowadays. Usually this happens as CentOS users hope that it should be more stable, tested and secure then other distributions as being derived from an enterprise commercial one. This might be true for most cases, but while developing PyHP we found a lot of “unknown mysterious bugs” that happened only on CentOS. After some investigation we found that apr_stat on CentOS always returns 0 as file size (this made quite interesting to allocate buffers or use mmap to read files) and also that bucket brigades had a strange behaviour, and as strange I mean that in some conditions they never considered terminated the […]

PyHP Database Session backend available

PyHP got the ability to save sessions on a database, the new PyHPSessionBackend config variable can be set to “db” or “file”, and PyHPDBSessionUser, PyHPDBSessionPass and PyHPDBSessionUri can be specified to set which database to use to store sessions and which user to access the database. This works only on mysql as mysql is currently the only database supported by the pyhp database backend. Sessions will be saved in the pyhp_sessions table which will be created by pyhp itself, so remember to give to the user you choose the ability to create tables inside the selected database.

PyHP-SVN got a new parser

PyHP got a new parser on subversion repository (click here to download), the new parser is still experimental and needs a lot of testing, but it has some interesting new features: Parsing errors reporting Block based indentation Faster parsing and inclusion First of all, now parsing errors like unmatching tags are reported on pyhp log. It will be reported the line and the file for which the error has happened (also if the file has been included). Next now you can indent your code as you wish inside your <?pyhp?> code blocks. PyHP will reformat the indentation based on the first line indentation. You will just have to indent your code in the same way inside the <?pyhp?> block, but […]

PyHP Sessions support improvements

Good news for PyHP. Latest SVN version got a few bug fixes and a big session management improvement. Now session collision is handled in a more coherent way, it’s a major improvement and I suggest to everyone using it to upgrade to svn revision. Also a few fixes have been implemented to catch programming errors by the developer that caused PyHP to crash making it more stable.

PyHP now supports multiple headers

SVN revision 24 of PyHP now supports multiple headers! This broke code that iterates over the old headers_in dictionary because now every value inside headers_in is a list instead of a string. On the other side code writing inside headers_out should continue to work because it is possible to insert both a string or a list inside headers_out dictionary to set only one header or multiple headers. You can try it from here: http://pyhp.svn.sourceforge.net/viewvc/pyhp.tar.gz?view=tar
