• How do I see the whole HTTP request in Rails

  - by akafazov

  Hi, I have a Rails application but after some time of development/debugging I realized that it would be very helpful to be able to see the whole HTTP request in the logfiles - log/development.log, not just the parameters. I also want to have a separate logfile based on user, not session. Any ideas will be appreciated! Angel

• Ruby 1.9 Ramaze App Failing with "Illegal instruction"

  - by pkulak

  I've got an app that I'm trying to get working again after wiping my system and installing Snow Leopard. I installed Ruby 1.9 from Macports (now a later version) and the dev server starts up just fine, but then dies on the first request, only telling me "Illegal instruction". I have no idea what's causing this or even how to go about debugging it. Does anyone have any ideas?

• Ninject and Custom Controller Factory

  - by Baddie

  I'm using MEF with ASP.NET MVC as demonstrated at http://blog.maartenballiauw.be/post/2009/06/17/Revised-ASPNET-MVC-and-the-Managed-Extensibility-Framework-(MEF).aspx. When I try to use Ninject, it seems that nothing gets injected. I did some debugging, and when I reverted to the original controller factory the injection worked. What needs to be changed, or what does Ninject need in terms of controller factories for it to work?

• When developing Silverlight apps is it ok to just to run directly from the test page?

  - by John

  Hi, When I create a new Silverlight project in Visual Studio it creates a new web project in the same solution and wires it up to run in a local server when developing and debugging. Some demo projects I have downloaded just run directly from the test page on disk. When developing what are the benefits of running via a server? What would you lose by just running from the disk?

  - by mckoss

  I'm debugging my Android application using the AVD (Android Virtual Device). When I try to enter text in a text field, my characters are being interpreted as Japanese (or Chinese?) in the IME. I don't know how I got into this mode or how to get out of it (I just want to enter alphabetic keys)? Here's a screen shot: http://u.go2.me/3cn

• Ad-hoc retreival of data from SQL Server varbinary column

  - by Daniel Fortunov

  I would like to retreive some binary data from a varbinary(max) column in a SQL Server database for debugging purposes. What is the easiest way to get this data into a local binary file, preferably without having to write a throw-away console application? I have tried using SQL Server Management Studio but this returns a hex encoded binary string, rather than raw binary data (even with the "results to file" option).

• Using Cmake with GNU Make: How can I see the exact commands?

  - by Nils

  I use Cmake with GNU Make and would like to see all commands exactly (for example how the compiler is executed, all the flags etc) GNU make has --debug, but it does not seem to be that helpful are there any other options? Does Cmake provide additional flags in the generated Makefile for debugging purpose?

• Apple script Editor, write message to the "Result" window

  - by Patrick

  I am using the Mac OS X Apple Script Editor and (while debugging) instead of writing a lot of display dialog statements, I'd like to write the results of some calculation in the window below, called "Result" (I have the German UI here, so the translation is a guess). So is there a write/print statement that I can use for putting messages in the "standard out" window? I am not asking to put the messages in a logfile on the file system, it is purely temporary.

• What is the difference between using $1 vs \1 in Perl regex substitutions?

  - by Mr Foo Bar

  I'm debugging some code and wondered if there is any practical difference between $1 and \1 in Perl regex substitutions For example: my $package_name = "Some::Package::ButNotThis"; $package_name =~ s{^(\w+::\w+)}{$1}; print $package_name; # Some::Package This following line seems functionally equivalent: $package_name =~ s{^(\w+::w+)}{\1}; Are there subtle differences between these two statements? Do they behave differently in different versions of Perl?

• OpenID authentication in Ruby on Rails

  - by martinatime

  I am a neophyte with Ruby on Rails but I've created a couple of small apps. Anyway, I'm really interested in OpenID and I would like to implement OpenID authentication and maybe some Sreg stuff in a Rails app. All of the research that I have done has come up with articles that are out of date or just don't work for me. Since I'm so new to Rails I'm having difficulty debugging the issues so... What is the best way to implement OpenId in Rails? Thanks

• Handling apostrophes, php and pgsql

  - by running4surival

  For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

• Can I rename Main.mxml?

  - by Randyaa

  We have several Flash objects included in our project. We call each one a specific type of widget... For readability/debugging purposes I'd like to rename Main.mxml to something else. At first this seemed easy, as it would be just a setting in our maven configuration (we're using flex mojos to build our swf). However; changing the sourceFile from Main.mxml to MyWidget.mxml doesn't seem to do it. Any thoughts?

• Is there an XmlWriter that writes a colorful HTML-formatted output for displaying XML in a webpage?

  - by Vilx-

  I've got a bit of XML I want to display on my ASP.NET website as-is (for debugging purposes), and it would be nice if it was colored. This should be easy to achieve with the right kind of XmlWriter, but I don't have the time to make one myself. Is there an existing (free) component that can do this?

• iis7 integrated mode asp.net 4.0 forms authentication problem using IE8

  - by FiveTools

  Anyone experience any issues with IIS7, integrated mode forms authentication while using IE8? I have a website with a login form, once logged in, any postback causes the user to be logged out. This doesn't even happen consistently, sometimes I can login and not experience this issue, other times it happens instantly. I can not replicate the problem in any other browser and I cannot replicate on my development machine running / debugging vs2010.

• How to access xmlParserCtxt structure from within xmlSAXHandler callbacks?

  - by Lux In Tenebris

  I'm parsing (X)HTML pages content with libxml using the following call: htmlDocPtr doc = htmlSAXParseDoc(content, NULL, &html_handler, NULL); But for debugging purposes I need to analyze some of the current node properties in the start/end element callbacks. I know that the fourth argument of htmlSAXParseDoc can be used to pass any user defined data to the callbacks, but I don't have a pointer to xmlParserCtxt.
