Access file problems on Windows #39

Closed kpymkata closed 12 years ago

kpymkata commented 12 years ago

Hi folks,

I am having an unexpected behavior of the gem under Windows. My environment is: 64-bit Window 7, 64-bit Sun JDK 1.6.0_37, 64-bit JRuby 1.6.8, Rails 3.2.2, acts_as_indexed 0.7.8, devise 2.0.4.

While running my Rails application I got the following problem, coming from the Devise gem:

IOError in Devise::RegistrationsController#create

The process cannot access the file because another process has locked a portion of the file

While debugging the application with RubyMine IDE, I found that the issue is occurring in acts_as_indexed/lib/acts_as_indexed/storage.rb, line 174, method lock_file. Strangely enough, in the debugger I found that the class variable @@is_windows was having the nil value, which is treated as false from a boolean perspective.

By applying a runtime replacement of the value to "true" in the debugger, my application worked fine. So I guess that this is a bug.

Kindest Regards, Krum.

Hi Krum.

Yep, bug. The OS detection naively uses the Platform, so will be fooled by JRuby.

I'll either fix this in the next release, or provide a way to configure the storage without locks.

Thanks.

Thanks!

Indeed, I could not hit the problem on Linux.

Hi Krum.

There is now a configuration option for this. See the above commit. Development branch only at the moment.

Thanks.
