newlisp with libmicrohttpd and libevent(evhttp)

[irr]

Hi,



  I am trying to use libmicrohttd with newlisp and unfortunately, after about 4089 function calls, the code fail with [ERR: call or result stack overflow : MHD_create_response_from_data@7F6AF7B03D80] using:

  > ab -n 4089 -c 100 http://localhost:8081">http://localhost:8081



  The code is very simple: https://github.com/irr/newlisp-labs/blob/master/microhttpd/hello.lsp">https://github.com/irr/newlisp-labs/blo ... /hello.lsp">https://github.com/irr/newlisp-labs/blob/master/microhttpd/hello.lsp

  (just translated from C version: https://github.com/irr/newlisp-labs/blob/master/microhttpd/hello.c">https://github.com/irr/newlisp-labs/blo ... pd/hello.c">https://github.com/irr/newlisp-labs/blob/master/microhttpd/hello.c)



  The same happens with (using libevent + evhttp):

  https://github.com/irr/newlisp-labs/blob/master/libs/evhttp.lsp">https://github.com/irr/newlisp-labs/blo ... evhttp.lsp">https://github.com/irr/newlisp-labs/blob/master/libs/evhttp.lsp



  Any help?

This is fixed in the current inprogess version - assuming you can compile yourself:



http://www.newlisp.org/downloads/development/inprogress/">http://www.newlisp.org/downloads/develo ... nprogress/">http://www.newlisp.org/downloads/development/inprogress/



There will be a maintenance release 10.4.4 by the end of this week.

"Fixed a result stack overflow problem on callback's."



Great news! I tried this version and everything is fine.



Thanks,
