P4Eclipse allows me to edit file without checking it out

Question

I installed P4Eclipse plugin in Eclipse. However, I noticed that Eclipse allows me to edit a file, but it doesn't automatically check it out from Perforce repository. So, after I edited the file, then go to P4V, the recently modified file won't show up in default change set. Any suggestion on what to look into here?

Thanks.

Answer 1

Actually, after some investigation, I realized that this is indeed related to file system read/write permission. For other reason, I accidentally changed sources files in my perforce workspace to readable. This is why I get to modify them in eclipse without seeing a warning, and at the same time Perforce doesn't realize that these file have been changed.

Manually fixing the permission on those source files resolved this problem.
