• Field name being converted in Unit Tests [rails]?

  - by yar

  I am noting this strange behavior where one of my fields -- receive_empresa_test_info -- has worked fine though it's always been referred to as receive_empresa_info. In Functional Tests, though, the real field name is receive_empresa_test_info. What is going on here? Might this be some part of the Rails environment that I'm missing during testing?

• xdebug profiler output strange results

  - by nic28

  I'm using xdebug to profile some PHP code on Windows and using WinCacheGrind/Webgrind to analyse the output, but I'm getting some strange results. Specifically, the total cumulative time for a single method is greater than 100%! How is it possible that more time is spent executing this function's code and all the functions that it calls than the total time it took to execute the whole script? What am I missing here?

• Invoking a function of library libfprint in Python

  - by Ivanelson

  I need help to call a function(Struct C) that detects the devices, so I'm calling the function this way: from ctypes import * fp = CDLL('./libfprint.so.0') fp.fp_discover_devs.argtypes = None fp.fp_discover_devs.restype = c_char_p ret = fp.fp_discover_devs() print ret # is "0" That is not detected any device, because the return is "0". See the documentation of the function: I'm using Ubuntu and I downloaded the "fprint_demo" and works perfectly. Did you install any package missing? Thanks.

• Memory leaks in libxml2.2

  - by KSH

  I am using libxml2 to parse xml content in my iPhone app. The xml content is downloaded from a server similar to the Apple's own TopSongs sample app. When I check for leaks using the Instruments tool, I see memory leaks being reported on xmlNewParserCtxt, xmlNewInputStream and xmlAllocParserInputBuffer. I have called xmlFreeParserCtxt(context) at applicable places (dealloc). Am I missing something else ? Is this a known issue to contend with when using libxml2 parsers ?

• Oracle scheduler job log output

  - by JOTN

  I'm using dbms_scheduler to execute a PL/SQL stored procedure. I would like to be able to have that code create some text logging output and associate it with the run to verify it's working, but I can't find anything to do that in the docs. Is there a facility to do this that I'm missing? This is an 11g database running under Unix. It would be real nice if I could use dbms_output so I could also run it from sqlplus and get output.

• Subversion Question - How to skip a revision...

  - by Albert

  So say I have the three latest revisions of an aspx file: 55,56, and 57. Revision 56 added a feature that I want to remove, but I also want to have the new features deployed in version 57. Is there any way I can merge version 55 with 57, leaving revision 56 out of the picture? If it matters, I'm using Tortoise SVN and Visual SVN, but I normally just use Tortoise. Thanks for any ideas.

• Memcached for PHP 5.3

  - by Industrial

  Hi everyone, I have looked everywhere for some clues on how to run the Memcached extension in my WAMP windows development environment (thats right, the memcached with an D in the end, not memcache). I already use memcache (without the D), but it would be handy to take part of memcached's more extended multiple-server features. How can I get this up and running? Thanks

• High performance SSL client with connection pooling session caching etch on Windows

  - by Yucong Sun

  Hi there, I'm looking for a fast SSL socket client basically talks SSL with remote service and I need features like connection pooling/limiting so that my other client calling this ssl socket can basically issue as many as requests and it will handle it peacefully. I looked into openssl s_client, but it says it's only for testing purpose, is there a handy tool avaiable? STunnel seems to be okay, but don't have that connection limiting option I need. Cheers.
