Re: Fwd: Windows File permissions are not being inherited - Cygwin 1.7 - Windows 7
If you read again very carefully, you will see that I modified permissions AFTER I noticed they were messed up. Ok? In my case, these additional permissions were allowing everyone to modify files. Not harmful at all, indeed. I do not remember all the details, I remember these permissions were everywhere. So I just replaced everything with proper permissions and disabled acl support in cygwin. The only problem was setup.exe but now I compiled it with a modification and this last problem gone. I understand that I do not have all the details required for a bug report. And it wasn't an attempt to report a bug. I was asked why I care about permissions, so I answered. Anyway, the problem is solved now, I also submitted an easy patch to setup.exe source for everyone who want to get rid of this problem as well. If I ever get into a problem with permissions again, I will try to make a proper bug report instead of just fixing permissions.

I tried to point out that your definition of messed up is the opposite of Andy's. To you, the default permissions provided by setup.exe are messed up.

Yes, the more I read, the more I come to believe that the disconnect here is in the definition of correct and acceptable permissions. Your definition differs from that of the Cygwin developers. It's good that your permissions changes worked for you, but it's possible that they won't work for everyone.

Your answer was simply an assertion that there possibly was and may still be something wrong with the permissions handling under Cygwin, but that you also haven't confirmed that recently. The details really would be helpful and likely necessary if you would like to have your patch accepted by the maintainers of setup.exe. The only other option is to independently maintain your patch and rebuild your version of setup.exe any time the upstream version changes. This won't help most users, though, because they will either not know about your patch or not care to build their own setup.exe without having any evidence of an existing problem and assurance that your change doesn't introduce other problems. If you're satisfied with your solution, so be it, but you could pretty quickly gather the necessary details for a bug report by performing a second installation of Cygwin into a new directory and reporting the flawed permissions. That could lead to the acceptance of your patch or something similar to the benefit of everyone. -Jeremy -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

No, my patch can't be accepted as it removes permissions handling completely. It wasn't me who started the thread and I believe, my patch can be of interest for anyone else who will search for a solution for this specific problem. Anyway, I don't see how an option to switch off permissions handling by setup.exe can harm while there is similar functionality in cygwin itself. My very limited understanding of C is not enough to do this, and I never worked with GUI applications. But I will see if it can be done via command line switch and if I succeed, I will submit a proper patch. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

There we go, a proper patch.

Because I prefer to keep things under control. And I don't think it will require a huge amount of work to disable working with permissions in setup.exe with command line switch. I started to worry about it because cygwin failed so much with permissions, having both cygwin-specific and inherited ones (copied) at the same time, resulting in complete mess. A non-privileged user could modify cygwin configuration files in /etc and it was not possible to do something about it. That is when I decided to control permissions myself, but cygwin setup overwrites permissions on every install, including files in /etc, messing up everything.

That appears to be a mess of your own making. Otherwise, concrete bug reports please. The OP's complaint here was that permissions aren't inherited, so I've got no idea what you're on about. A non-privileged user could modify cygwin configuration files in /etc and it was not possible to do something about it. Well, I don't know what you did, but I install Cygwin as administrator and work as an ordinary user, and no, I can't modify anything in /etc. And that's no accident of course, because a lot of work has gone into mapping POSIX permissions to NTFS permissions in a sensible way.

That solved all problems, until I updated installation using setup.exe. Believe me or not, but I really did not touch any permissions until I noticed that strange behaviour. And I am the only administrator. Machine is not a part of any domains. So, unless it's a kind of black magic, there was (and maybe still is) some issue with permissions in cygwin. That is why I don't want to use them.

And I don't think it will require a huge amount of work to disable working with permissions in setup.exe with command line switch. I started to worry about it because cygwin failed so much with permissions, having both cygwin-specific and inherited ones (copied) at the same time, resulting in complete mess. That appears to be a mess of your own making. Otherwise, concrete bug reports please. The OP's complaint here was that permissions aren't inherited, so I've got no idea what you're on about. A non-privileged user could modify cygwin configuration files in /etc and it was not possible to do something about it. Well, I don't know what you did, but I install Cygwin as administrator and work as an ordinary user, and no, I can't modify anything in /etc. And that's no accident of course, because a lot of work has gone into mapping POSIX permissions to NTFS permissions in a sensible way.
