Sharing Seaside URLs between users (security) + what is actual way for session expiration page

by Petr Fischer

Hello, two questions about Seaside sessions: 1) URL sharing between different users - what if "boss" shares URL from his browser and send it to another regular user - of course, easy way, whole URL with session (_s=xxxx) - when another/regular user opens that link -> whole "boss" session opens in regular user's browser, with all "boss" permissions, UI state etc etc - very bad, is there any solution for this? Rewrite every (!) URL with updateURL: is not solution :( 2) What is the actual way for "session expiration/login page"? There is few tutorials and books on the inet - but info about session expiration is obsolete :( Methods from tutorials not exists in Seaside 3.2.0. Some trick with WAApplication subclass is actual? Thanks very much! pf

Re: [Pharo-users] doesNotUnderstand: infinit loop

by Guille Polito

Hi Hilaire, all, I started digging this morning on this issue, and I see why we can have such problems. Apparently, there is some strange case that produces a bug in UIManager. To explain it with code, the UIManager should satisfy allways the following invariant. "If executed from a workspace/playground. i.e., the UI process itself:" UIManager default uiProcess == Processor activeProcess. => true Somehow, in the image you provided me, it is not the case. I'm still taking a look at what would cause this. And I also think we still have this bug in pharo 6 (and thus pharo 5) because I found it lately very often. In the meantime, if you find that your image is causing you these problems, you can workaround it by executing: UIManager default spawnNewProcess. Once you do that, the ui process should come back to a correct state and the debugger should behave as expected.

In >>#name:attachToCFile:writable: you create a SQFile* out of a FILE* (OSSCFile) but judging the comment it doesn't work. The 32/64 bit issue can be solved by using FFIExternalStructure to model SQFile but the question if the VM was built with large file support on GNU/Linux is a tricky one. So maybe we create another primitive to convert a FILE* to a SQFile* (and have it manage the lifetime of that memory?)?

Imagine you want to exit the image in case the file /exit changes. You will charge inotify to watch this filepath and if the fd becomes readable you already know the answer, you don't have to read the event. But true if I have a Socket or FileStream I can do blocking read on it as well. > I think you could dig a bit in OSSPipe, OSSAttachableFileStream and their usage. All classes have class comments, all methods are also documented, and there is quite some documentation in [1]. Will look again but I didn't see anything obvious. E.g. primCreatePipe seems to already return two SQFile* ("fileId")? cheers holger

Hi, You should close the respective Glamour browser. Could it be that you have an opened inspector? If so, try closing it and see what happens.
