To see package descriptions without setup, you can look inside setup.ini. In addition to the short description (sdesc) displayed by setup, it has a long description (ldesc), though sometimes that is just a repeat of sdesc.

So you want, what, MSDN for Cygwin? Not going to happen. MSDN documents everything in Windows because it all comes from one place. Cygwin may appear to you to come from one place, but only because all of its contributors go out and grab things from all over the net and push them into the Cygwin repositories.

Is there a tool for viewing all cygwin/GNU Software submissions
Is there a general tool that will allow someone to see the definition of all software in cygwin and allow browsing of libraries for content? If there is not, how can I go about creating one (any ideas)? What I would like to see for executables is a setup-like tool to pretty print information on all available software without going through setup. Where a library is included, I would like to see something about the routines included in the library. Info does a great job of showing information on executables which have been downloaded (although its presentation format is really bad), but provides no insight on available but not downloaded software. 'setup' provides a thumbnail description of all available software, but you have to use it in conjunction with the internet, and viewing and searching is laborious. And I don't know if there is anything which provides some brief information on library contents. I think for libraries you have to go to the provided application developer documentation or use one of the tools to read the library contents. So, anything there or anything I can do (to make it 'there'). art -- 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 callstack after assert
Hello,
I was poking around with gcc and gdb and found that when I hit an
assert, I did not have a valid callstack/backtrace. Is this expected?
A little info:
* I am using Windows 7 and 8, 64-bit.
* I used the latest gcc (4.8.3) and gdb (7.8) that a fresh cygwin installed.
* uname -a reports:
CYGWIN_NT-6.1 C-MICKB 1.7.33-2(0.280/5/3) 2014-11-13 15:47 x86_64 Cygwin
* I compiled my program like so: gcc -g test_asserts.c
* I get a valid backtrace before the assert hits.
Thanks for any pointers,
Mick

Also, I removed the dependencies and then confirmed that simply stopping the cygserver process and restarting it eliminates the problem (of course, after restarting the XWin and terminal sessions). I had one additional thought...sometimes (like today) I work from home and wondered if perhaps a reboot without access to the network might cause the problem. However, I cycled cygserver WITHOUT connecting to my VPN to the office, and the problem still went away, so apparently a network connection to the corporate AD server is not needed (probably uses my local cache, right?) cygserver.trace Description: cygserver.trace cygserver.stderr Description: cygserver.stderr -- 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

Once startup goes smoothly, your current AD code works fine for me. The only problem I'm having is that sometimes start up failsprobably because it occurs too rapidly after reboot, and stuff on this old POS computer is running so slowly that something times out, causing cygserver to cache bad information. I'll bet that something a lot simpler would solve this problem than coding to ignore certain group codeseither a delayed service start on my end, or perhaps some kind of TTL on a cached cygserver entry that originally timed out. I will try to regenerate a failure and get you the requested strace from cygserver soon.

Yes, I guess I'll have to date myself now. I've worked here with the same user ID since 1975 (full time since 1980), so I span basically the entire non-mainframe computer era. So what you are suggesting is quite likely, and it would not be surprising for clean-up work to have been neglected. A quick look in our AD shows numerous things such as "Legacy local groups" and "Legacy Mailboxes". One concern I have here is that when I dig down into AD to "DC=dow,DC=com,OU=Dow Users,OU=Employees" and find what I believe is my current active record I find a record with "U074036" (capital 'U') whereas the record we saw as my "UID" earlier in this thread was with a lowercase 'u'. I found this by searching for sAMAccountName=u074036, and it is the only record found by this search.

Two things to keep in mind: - It's not actually clear yet if it's a sidHistory entry or some SID created by another mechanism. - Even if it's sidHistory, it may be *very* old. Did you work at the company already back in NT4 times? That might explain the sidHistory entry and the total lack of files still having this SID in its ACL. As far as I know, Microsoft suggests to remove the sidHistory entries as soon as they are not needed anymore.
