  • Live javascript debugging by recording function calls and parameters

    - by Jenko
    Is there a debugging system that allows me to record javascript function calls and their parameters as they occur? this would allow me to trace and debug applications in live/client situations without the performance hit due to manual logging. Edit: I'm not talking about manually calling functions using a 'console' window and viewing the results, or manually adding 'trace' or 'log' commands into my javascript. I need it to work with any running javascript.

  • Ideas for a C/C++ library

    - by Mohit Deshpande
    I thought one of the best ways to familiarise myself with C/C++, is to make a helpful library. I was maybe thinking like a geometry library, like to calculate areas, surface area, etc. It would be useful in game programming. Or maybe an algebra library, like for different formulas like the distance formula, quadratic formula, etc. Or maybe like a standard library for very simple functions, like calculating the number of items in an array.

  • Using mcrypt to pass data across a webservice is failing

    - by adam
    Hi I'm writing an error handler script which encrypts the error data (file, line, error, message etc) and passes the serialized array as a POST variable (using curl) to a script which then logs the error in a central db. I've tested my encrypt/decrypt functions in a single file and the data is encrypted and decrypted fine: define('KEY', 'abc'); define('CYPHER', 'blowfish'); define('MODE', 'cfb'); function encrypt($data) { $td = mcrypt_module_open(CYPHER, '', MODE, ''); $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND); mcrypt_generic_init($td, KEY, $iv); $crypttext = mcrypt_generic($td, $data); mcrypt_generic_deinit($td); return $iv.$crypttext; } function decrypt($data) { $td = mcrypt_module_open(CYPHER, '', MODE, ''); $ivsize = mcrypt_enc_get_iv_size($td); $iv = substr($data, 0, $ivsize); $data = substr($data, $ivsize); if ($iv) { mcrypt_generic_init($td, KEY, $iv); $data = mdecrypt_generic($td, $data); } return $data; } echo "<pre>"; $data = md5(''); echo "Data: $data\n"; $e = encrypt($data); echo "Encrypted: $e\n"; $d = decrypt($e); echo "Decrypted: $d\n"; Output: Data: d41d8cd98f00b204e9800998ecf8427e Encrypted: ê÷#¯KžViiÖŠŒÆÜ,ÑFÕUW£´Œt?†÷>c×åóéè+„N Decrypted: d41d8cd98f00b204e9800998ecf8427e The problem is, when I put the encrypt function in my transmit file (tx.php) and the decrypt in my recieve file (rx.php), the data is not fully decrypted (both files have the same set of constants for key, cypher and mode). Data before passing: a:4:{s:3:"err";i:1024;s:3:"msg";s:4:"Oops";s:4:"file";s:46:"/Applications/MAMP/htdocs/projects/txrx/tx.php";s:4:"line";i:80;} Data decrypted: Mª4:{s:3:"err";i:1024@7OYªç`^;g";s:4:"Oops";s:4:"file";sôÔ8F•Ópplications/MAMP/htdocs/projects/txrx/tx.php";s:4:"line";i:80;} Note the random characters in the middle. My curl is fairly simple: $ch = curl_init($url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, 'data=' . $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $output = curl_exec($ch); Things I suspect could be causing this: Encoding of the curl request Something to do with mcrypt padding missing bytes I've been staring at it too long and have missed something really really obvious If I turn off the crypt functions (so the transfer tx-rx is unencrypted) the data is received fine. Any and all help much appreciated! Thanks, Adam

  • Watchpoints w/xDebug in Eclipse PDT?

    - by continuum
    Has anyone gotten watchpoints to work when debugging PHP with xDebug and Eclipse? The way I understand it, I'm supposed to be able to select a watched variable in the expressions view or select a variable in the Variables view during debugging, and then select Run-Toggle Watchpoint. But Toggle Watchpoint is constantly greyed out. All my other debugging functions work fine: breakpoints, step in, out, over, etc. Just can't get a watchpoint working.

  • Android: View.getTag/setTag and IllegalArgumentException

    - by Sparafusile
    Yes, I know you need a unique resource id when calling the version of these functions that requires a key, but I cannot for the life of me figure out how to create a resource id that can be used in this way. A final variable in my class wont work and neither will a hard coded value. Both threw an IllegalArgumentException. So what gives, how do you use these methods? Spara

  • Delphi - Differences between CompareStr and CompareString

    - by Bourgui
    Hi all, I'm hoping someone can shed some light on this for me What are the differences, in Delphi 2009, between the CompareStr (defined in SysUtils) and CompareString (from Windows API) functions? Both let you specify the locale to be used, is the Windows one simply more "complete", due to the available comparison flags? Is one consequently faster than the other? Thanks!

  • Is there a substitute for blockproc in Matlab?

    - by SetchSen
    I've been using blockproc for processing images blockwise. Unfortunately, blockproc is part of the Image Processing Toolbox, which I don't have on my personal computer. Is there a combination of functions in base Matlab that can substitute for blockproc? My initial guess was to use im2col to transform each block into columns, and then arrayfun to process each column. Then I realized that im2col is also a part of the Image Processing Toolbox, so that doesn't solve my problem.

  • How to ANSI-C cast from unisigned int * to char *?

    - by user314290
    I want these two print functions to do the same thing: unsigned int Arraye[] = {0xffff,0xefef,65,66,67,68,69,0}; char Arrage[] = {0xffff,0xefef,65,66,67,68,69,0}; printf("%s", (char*)(2+ Arraye)); printf("%s", (char*)(2+ Arrage)); where Array is an unsigned int. Normally, I would change the type but, the problem is that most of the array is numbers, although the particular section should be printed as ASCII.

  • Low level Android Debugging

    - by L4N0
    Is there a way to trace through function calls at the lowest levels of the Android system? Right now when I debug in Eclipse, it goes through the source files that are located inside the frameworks folder, but is it possible to go even lower? For example show what functions are being called from the libcore folder. I am also interested to find how it communicates with the linux kernel at the bottom of the layers. Is there a way to do this? Thanks
