[ANNOUNCEMENT] TEST RELEASE: Cygwin 2.2.0-0.3
Hi Cygwin friends and users, I released a new TEST version of Cygwin. The version number is 2.2.0-0.3. This test release needs some more good old-fashioned testing. New, user-visible change: - When started from a non-Cygwin process, check if $HOME starts with a slash (absolute POSIX path). Otherwise ignore it. Addresses: https://cygwin.com/ml/cygwin/2015-07/msg00344.html There was also a bugfix in the trampoline function installed by makecontext. On x86_64, the function missed to install shadow space for the argument registers as required by the MS ABI. As a result, using makecontext could suffer a buffer overflow. Thanks to Glibc's tst-makecontext2 testcase. On the plus side, with this patch, the entire glibc testsuite for setcontext/makecontext now succeeds. While the other new features in this release are only interesting to developers again, there's an intrusive under-the-hood change which just needs testing in as many scenarios as possible. tl;dr == Details aside, the interesting thing here is plain and simple this: Does your stuff still work as with 2.1.0? No regression? The boring details: The under-the-hood change is this: Certain functions in Cygwin were using very big buffers (32K, 64K, and more) on the stack. While this is not much of a problem with the normal stacksize of 2 Megs, it's been a lot of stack pressure on an application-provided patch. Yada, yada. For devs only: NEW: sigsetjmp and siglongjmp were only implemented as macros so far. POSIX requires functions longjmp and siglongjmp to exist. 2.2.0-0.2 adds sigsetjmp and siglongjmp functions. 2.2.0 comes with four new functions: getcontext, setcontext, makecontext and swapcontext. My own testing included two very simple self-written STCs, as well as the example code from http://linux.die.net/man/3/makecontext, as well as the glibc testcases for setcontext and makecontext. As with the sigaltstack stuff, I'd be grateful if curious developers would give this implementation a test. If it doesn't work as desired, please consider to create simple reproduces in plain C. Discussing aspects of this implementation may be best handled on the cygwin-developers mailing list or the #cygwin-developers IRC channel on Freenode.

Re: ACL Hell
Sorry for the late reply. Ran both commands from an elevated shell and it still doesn't work. I see this was discussed before but there was no concrete conclusion. https://www.cygwin.com/ml/cygwin/2013-04/msg00066.html The two options that do work so far are: 1. Run cygwin as administrator 2. Disable UAC altogether (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA=0 in the registry) I use the first option at work and the second one at home. Cheers.

Re: db_home setting in nsswitch.conf is ignored.
Thank you both for trying to help me out.

So many symbols not allowed to be there. Not only does it look strange, but I can't tell where it's being set. Under System > Advanced > Environment Variables, there is no HOME variable set. When I put one in, it's ignored. If I type "set home" from the command prompt I get: HOME=SERVER/USERS5:USERS\SHAUN HOMEDRIVE=C: HOMEPATH=\Users\shaun I guess that would suggest the admins are using it to build up the full path dynamically for some reason. I'll need to talk to them about making any modifications. > On a second look into your OP, I'm also a bit puzzled about the > settings you made in /etc/nsswitch.conf. >From the documentation, it looked like "db_home: /home/%U" should solve my problems. When that didn't have any affect, I was just grasping at straws. I didn't try those all at once, I just wanted to show the options I had tried. Cygwin works perfectly in my home environment and on a virtual machine I have at work using a standard Windows installation. My work environment has caused problems with other programs in the past, but it seemed like this HOME variable situation could be bypassed by the "/etc/nsswitch.conf" file. I'll talk with the admins about Cygwin and see if they want to help me get this issue worked out.

[ANNOUNCEMENT] Updated: stow-2.2.0-2, New: perl-Stow-2.2.0-2
A new version of stow, 2.2.0-2, is available in the Cygwin distribution. This is a Cygwin-only release, that fixes a packaging problem where the perl Stow module was in the wrong location. The Stow module has also been separated out into the new perl-Stow package, which stow now depends on. stow manages the installation of local software packages by creating sets of symlinks from the installed location (e.g. /usr/local) to a stow directory (e.g. /usr/local/stow/emacs) where the real files live. This allows you to keep packages separate, while making them appear to be installed in the same place. Andrew E.

I think admins can disallow changing your default user environment via policy. But that only means you can't change the env for the *first* process in a process tree. See below. > > With the "SET" command in a Windows command prompt I can see: > > > HOME=SERVER/USERS5:USERS\SHAUN > > That's suspicious. So many symbols not allowed to be there. I agree. For a start, this behaviour of Cygwin has not chaged since at least 2002: When being started from a non-Cygwin process (e.g. cmd, explorer), Cygwin checks if the environment variable $HOME is already set. If so, it uses it verbatim. Otherwise, it generates a value for $HOME from the user's passwd DB entry or, if that fails for some reason, falls back to generate a POSIX path from $HOMEDIR/$HOMEDRIVE. The above value of $HOME is really a problem here. Not only that it exists and doesn't actually reflect your HOME, it's also not starting with a slash and thus is evaluated as a *relative* path. Therefore your resulting HOME will depend on the current directory you're starting the Cygwin process from. The fact that your actual home directory in the passwd DB is set differently doesn't matter anymore then. I.e., the output of $ getent passwd will very likely show something different as pw_dir entry. On a second look into your OP, I'm also a bit puzzled about the settings you made in /etc/nsswitch.conf. No offense meant, but it seem you just used some arbitrary settings without actually reading what they mean and how to configure them (e.g. cygwin, desc). Is there a problem understanding https://cygwin.com/cygwin-ug-net/ntsec.html? I'm always grateful for hints how to improve the docs, even more so for patches to the docs. > > When you say it only works for entries taken from passwd DB, does that > > mean I need to create a "/etc/passwd" file in order to change the > > "db_home" directory with nsswitch.conf? > > No, she said that it only works if Cygwin has to retrieve these records from > DB.

Alternatively (if your admin is a BOFH), you can always drop HOME from your powershell env before starting a Cygwin process. Even more alternatively, what Cygwin *could* do in an upcoming version is to check the incoming $HOME for validity, i.e., is it an absolute POSIX path and does it resolve to an existing directory. If not, ignore it and try the entry from the passwd DB. However, I'm rather reluctant to do that. For one your case is a first. Such a change could also have surprising side effects. Maybe just checking for a leading slash would work in most environments, but still...
