what is the +hex in c++ stack traces?
What is the hex number after the method, e.g. +0x32f below? It matches arg0 and I suspect it''s the c++ "this" pointer, aka hidden first argument. I would like to confirm, though. Thanks, Joel --- XUL`PresShell::ProcessReflowCommands(int)+0x32f XUL`PresShell::FlushPendingNotifications(mozFlushType) +0x19e

before_filter: nil vs. true vs. false
Folks, My understanding of how filters work is that I should return true if everything is ok and false if not. How does the filter below work then (from the Rails Recipies book)? It would return nil if there''s a user in the session. Does nil count as true? before_filter :check_authentication def check_authentication unless session[:user] session[:intended_action] =

More idiomatic way of writing a filter
Is there a more elegant way of writing this? def verify_user @user = User.find_by_username params[:username] if @user.nil? message = xml.error do |xm| xm.message "User does not exists: #{params[:username]}" end render :xml => message return false else true end end Thanks, Joel --

where do kernel data types come from?
I have a script where I can freely reference struct nameidata*, struct vnode*, etc. on Snow Leopard. How does DTrace know about these data types? I understand things like #pragma D depends_on library darwin.d where darwin.d has typedefs. I can''t find definitions of nameidata and vnode in any D scripts, though. How does it work?

undefined method `use_transactional_fixtures=''
Folks, I checked my test_helper.rb and it has self.use_transactional_fixtures = true My code was generated with 1.1.2 and I''m using 1.1.3 right now after but the error persists. I googled for this issue and it appears that a require is missing or something like that. I can''t figure it out, please help! /opt/local/bin/ruby -Ilib:test

usdt probes vs pid$target
I added a couple of static probes to Firefox to measure actual work done. I could have used a pid$target probe with a function name but work is done within an if statement, which is where I placed the static probes. I''m wondering about my use, though. Is the following significantly more efficient than pid$target::FunName:entry and return? I heard somewhere that $target does not

dtrace overhead and proper measuring technique
I''m trying to time a function within Firefoxwith a pid$target probe [2]. e.g dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 13954 -s menu- construct.d -s sigcont.d elapsed: 12.7942481ms cpu : 7.7911194ms count : 40 times I''m also measuring Firefox startup time by running it arguments like this: ... file:///Users/joelr/work/mozilla/startup/startup.html#`python

putting a running app into trace mode
Suppose I have a USDT probe in Firefox and that I''m trying to catch the startup with a probe like this: proc:::exec-success /execname == "firefox-bin"/ { start = timestamp; } and stop tracing when Firefox hits this USDT probe: mozilla:::main-entry { exit(0); } How do I put the running firefox-bin into "trace mode" so that my USDT probe fires?

Armageddon
I''m just wondering what happened to Armageddon and whether people had any more information/news about it. I''ve thought about comet but I think that a flash socket would be easier to implement. Does Armageddon have the same drawbacks as other flash sockets, namely not working over port 80 (so the companies firewall blocks it)? -- Posted via http://www.ruby-forum.com/.

Using fixtures from IRB
Folks, I have the standard setup with auto-generated unit tests and fixtures. I edited the fixtures and the tests but would now like to test associations from irb. How do I do this? I''m not sure how to load my fixtures into irb, for example. Once they are loaded I would create objects, save them to the db and pull things out. Thanks, Joel -- http://wagerlabs.com/

return from memset on mac osx
Does dtrace have a problem catching the return from memset on Mac OSX? The script below catches the entry just fine but the return clause is never entered. Thanks, Joel --- pid$target::memset:entry /arg1 == 0/ { self->size = arg2; self->ts = timestamp; self->vts = vtimestamp; } pid$target::memset:return /self->size/ { @ts = sum(timestamp - self->ts); @vts =

More idiomatic way of doing this
Folks, I''m trying to write a validating filter that checks if the user exists and renders XML if not. Most of the controllers will be returning XML on some error or other so I''m including RenderError in ApplicationController. Is my approach a sound one? Also, is there a shorter and more idiomatic way of writing this: if @user.nil? render_user_exists

Storing additional data in the session
Folks, I''m using the session db table to store additional data. When a user logins I would like to store their user id in the session record and save that. I''m thinking of x = Session.find(session.id) and then x.save. Is this the right way to do it? Thanks, Joel -- http://wagerlabs.com/

Manually creating session objects
Has anyone tried manually creating session objects and storing them in the database? I''m taking about a setup where the ActiveRecord session store is used. I''m sharing the database with a non-Rails platform and extended my session table to include other data that I need to store when the user logs in. Thanks, Joel -- http://wagerlabs.com/

Manually triggering session restore
