Debugger seems broken with Rails 2.3.2


#1

With Rails 2.3.2 and ruby-debug 0.10.3 very weird things are happening.
Am I the only one?

Here is one of the weird behavior: in development mode, if I edit a
Model, I sometimes notice that the code doesn’t get reload when I issue
the ‘list’ command in the debugger. Therefore I bang my head not
understanding why my edits don’t make any change.

Therefore I have to ctrl+c and relaunch Thin. Anyone else ran in this
problem previously?

Best regards,

Did that ever work? Development mode reloading only works between
requests. Ruby-debug may also be caching its own copy of the source
somewhere.

I think it happens when I open another terminal and use script/console.
Well I wasn’t able to clearly identify the cause.

Another weird behavior, is that when the debugger kicks in, sometimes I
can directly access classes and objects without having to go into irb (I
think that applies when debugger is in a model), sometimes I need to
enter irb.

Another one: when entering irb, I sometimes see lot’s of error/warning
messages, and the request carries on as if the breakpoint didn’t exist.
If I reissue the request and enter irb, the second time the request
won’t carry on.

I saw somewhere that irb in debugger is an “experimental feature”, so
we’ll have to deal with it. Anyway I can do 99% of my debugging simply
by using pp to figure how things will get evaluated and the state of the
variables.

I’ve got the same problems

I’m running as regular

$ ruby script/server --debugger
reach the break point
(rdb:5)
trying to run irb
(rdb:5) irb
and
INTERNAL ERROR!!! Unrecognized switch: -debugger

Full trace here:

But if you run debugger with RAILS_GEM_VERSION 2.2.2 or 2.1.2,
everything works fine.
irb by itself and script/console works fine under 2.3.2

Ubuntu Linux 8.10
kernel 2.6.27-7-generic
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

Temporary solution: run debugger through

$ rdebug ./script/server
Have to push “c” after starting up

Anyway, better than nothing.
