#
# The whole library (including breakpoint_client.rb
# and binding_of_caller.rb) is licensed under the

# This will pop up an interactive ruby session at a
# pre-defined break point in a Ruby application. In
# this session you can examine the environment of
# the break point.
#
# You can get a list of variables in the context using
# local_variables via +local_variables+. You can then
# examine their values by typing their names.
#
# You can have a look at the call stack via +caller+.
#
# The source code around the location where the breakpoint
# was executed can be examined via +source_lines+. Its
# argument specifies how much lines of context to display.
# The default amount of context is 5 lines. Note that
# the call to +source_lines+ can raise an exception when
# it isn't able to read in the source code.
#
# breakpoints can also return a value. They will execute
# a supplied block for getting a default return value.
# A custom value can be returned from the session by doing
# +throw(:debug_return, value)+.
#
# You can also give names to break points which will be
# used in the message that is displayed upon execution
# of them.
#
# Here's a sample of how breakpoints should be placed:
#
# class Person
# def initialize(name, age)
# @name, @age = name, age
# breakpoint("Person#initialize")
# end
#
# attr_reader :age
# def name
# breakpoint("Person#name") { @name }
# end
# end
#
# person = Person.new("Random Person", 23)
# puts "Name: #{person.name}"
#
# And here is a sample debug session:
#
# Executing break point "Person#initialize" at file.rb:4 in `initialize'
# irb(#<Person:0x292fbe8>):001:0> local_variables
# => ["name", "age", "_", "__"]
# irb(#<Person:0x292fbe8>):002:0> [name, age]
# => ["Random Person", 23]
# irb(#<Person:0x292fbe8>):003:0> [@name, @age]
# => ["Random Person", 23]
# irb(#<Person:0x292fbe8>):004:0> self
# => #<Person:0x292fbe8 @age=23, @name="Random Person">
# irb(#<Person:0x292fbe8>):005:0> @age += 1; self
# => #<Person:0x292fbe8 @age=24, @name="Random Person">
# irb(#<Person:0x292fbe8>):006:0> exit
# Executing break point "Person#name" at file.rb:9 in `name'

# Will run Breakpoint in DRb mode. This will spawn a server
# that can be attached to via the breakpoint-client command
# whenever a breakpoint is executed. This is useful when you
# are debugging CGI applications or other applications where
# you can't access debug sessions via the standard input and
# output of your application.
#
# You can specify an URI where the DRb server will run at.
# This way you can specify the port the server runs on. The
# default URI is druby://localhost:42531.
#
# Please note that breakpoints will be skipped silently in
# case the DRb server can not spawned. (This can happen if
# the port is already used by another instance of your
# application on CGI or another application.)
#
# Also note that by default this will only allow access
# from localhost. You can however specify a list of
# allowed hosts or nil (to allow access from everywhere).
# But that will still not protect you from somebody
# reading the data as it goes through the net.
#
# A good approach for getting security and remote access
# is setting up an SSH tunnel between the DRb service
# and the client. This is usually done like this:
#
# $ ssh -L20000:127.0.0.1:20000 -R10000:127.0.0.1:10000 example.com
# (This will connect port 20000 at the client side to port
# 20000 at the server side, and port 10000 at the server
# side to port 10000 at the client side.)
#
# After that do this on the server side: (the code being debugged)
# Breakpoint.activate_drb("druby://127.0.0.1:20000", "localhost")
#
# And at the client side:
# ruby breakpoint_client.rb -c druby://127.0.0.1:10000 -s druby://127.0.0.1:20000
#
# Running through such a SSH proxy will also let you use
# breakpoint.rb in case you are behind a firewall.

* Removed breakpointer and Binding.of_caller in favor of relying on ruby-debug by Kent Sibilev since the breakpointer has been broken since Ruby 1.8.4 and will not be coming back [DHH]
To use the new debugger, start your server with script/server --debugger and insert a call to 'debugger'
(instead of 'breakpoint') where you want to jump into the debugger.
BACKWARDS INCOMPATIBILITY NOTE: You must remove the default line 12 from config/environments/development.rb:
config.breakpoint_server = true
This configuration option is no longer available. Rails will fail to start in development mode as long as
that's still present.

Breakpoint support is available through the script/breakpointer client. This
means that you can break out of execution at any point in the code, investigate
Debugger support is available through the debugger command when you start your Mongrel or
Webrick server with --debugger. This means that you can break out of execution at any point in the code, investigate
and change the model, AND then resume execution! Example:
class WeblogController < ActionController::Base
def index
@posts = Post.find(:all)
breakpoint "Breaking out from the list"
debugger
end
end
So the controller will accept the action, run the first line, then present you
with a IRB prompt in the breakpointer window. Here you can do things like:
Executing breakpoint "Breaking out from the list" at .../webrick_server.rb:16 in 'breakpoint'
with a IRB prompt in the server window. Here you can do things like:
>> @posts.inspect

# This will pop up an interactive ruby session at a
# pre-defined break point in a Ruby application. In
# this session you can examine the environment of
# the break point.
#
# You can get a list of variables in the context using
# local_variables via +local_variables+. You can then
# examine their values by typing their names.
#
# You can have a look at the call stack via +caller+.
#
# The source code around the location where the breakpoint
# was executed can be examined via +source_lines+. Its
# argument specifies how much lines of context to display.
# The default amount of context is 5 lines. Note that
# the call to +source_lines+ can raise an exception when
# it isn't able to read in the source code.
#
# breakpoints can also return a value. They will execute
# a supplied block for getting a default return value.
# A custom value can be returned from the session by doing
# +throw(:debug_return, value)+.
#
# You can also give names to break points which will be
# used in the message that is displayed upon execution
# of them.
#
# Here's a sample of how breakpoints should be placed:
#
# class Person
# def initialize(name, age)
# @name, @age = name, age
# breakpoint("Person#initialize")
# end
#
# attr_reader :age
# def name
# breakpoint("Person#name") { @name }
# end
# end
#
# person = Person.new("Random Person", 23)
# puts "Name: #{person.name}"
#
# And here is a sample debug session:
#
# Executing break point "Person#initialize" at file.rb:4 in `initialize'
# irb(#<Person:0x292fbe8>):001:0> local_variables
# => ["name", "age", "_", "__"]
# irb(#<Person:0x292fbe8>):002:0> [name, age]
# => ["Random Person", 23]
# irb(#<Person:0x292fbe8>):003:0> [@name, @age]
# => ["Random Person", 23]
# irb(#<Person:0x292fbe8>):004:0> self
# => #<Person:0x292fbe8 @age=23, @name="Random Person">
# irb(#<Person:0x292fbe8>):005:0> @age += 1; self
# => #<Person:0x292fbe8 @age=24, @name="Random Person">
# irb(#<Person:0x292fbe8>):006:0> exit
# Executing break point "Person#name" at file.rb:9 in `name'
# irb(#<Person:0x292fbe8>):001:0> throw(:debug_return, "Overriden name")
# Name: Overriden name
#

# for a list of them.
#
# Breakpoints can also be used remotely over sockets.
# This is implemented by running part of the IRB session
# in the application and part of it in a special client.
# You have to call Breakpoint.activate_drb to enable
# support for remote breakpoints and then run
# breakpoint_client.rb which is distributed with this

# Will run Breakpoint in DRb mode. This will spawn a server
# that can be attached to via the breakpoint-client command
# whenever a breakpoint is executed. This is useful when you
# are debugging CGI applications or other applications where
# you can't access debug sessions via the standard input and
# output of your application.
#
# You can specify an URI where the DRb server will run at.
# This way you can specify the port the server runs on. The
# default URI is druby://localhost:42531.
#
# Please note that breakpoints will be skipped silently in
# case the DRb server can not spawned. (This can happen if
# the port is already used by another instance of your
# application on CGI or another application.)
#
# Also note that by default this will only allow access
# from localhost. You can however specify a list of
# allowed hosts or nil (to allow access from everywhere).
# But that will still not protect you from somebody
# reading the data as it goes through the net.
#
# A good approach for getting security and remote access
# is setting up an SSH tunnel between the DRb service
# and the client. This is usually done like this:
#
# $ ssh -L20000:127.0.0.1:20000 -R10000:127.0.0.1:10000 example.com
# (This will connect port 20000 at the client side to port
# 20000 at the server side, and port 10000 at the server
# side to port 10000 at the client side.)
#
# After that do this on the server side: (the code being debugged)
# Breakpoint.activate_drb("druby://127.0.0.1:20000", "localhost")
#
# And at the client side:
# ruby breakpoint_client.rb -c druby://127.0.0.1:10000 -s druby://127.0.0.1:20000
#
# Running through such a SSH proxy will also let you use
# breakpoint.rb in case you are behind a firewall.
