I've run into a problem with flock while doing some parallel scripting
in bash (also seen in dash) on the latest 64-bit version of Cygwin
running on Windows 8.1. In the attached simple test case, the code
locks and unlocks a file in a loop. After the first iteration of the
loop is completed, this error is thrown:
0 [main] flock 7008 C:\cygwin64\bin\flock.exe: *** fatal error -
NtCreateEvent(lock): 0xC0000035
./test.sh: line 12: 7008 Hangup flock -x 5
However, the problem doesn't occur if I comment out the "while true
do" and "done" and call the script file from a while loop in another
bash script. I found a similar problem in an older thread (here:
https://sourceware.org/ml/cygwin/2011-08/msg00480.html) which may help
to shed some light on the issue, but the inner workings of the locking
system is a bit beyond me. My full Cygwin version is "CYGWIN_NT-6.3
1.7.33-2(0.280/5/3) 2014-11-13 15:47", and my cygcheck output is
attached along with the STC and flock's stackdump. The cygcheck output
has been edited to remove one license server address.
Thanks,
Kyle R.

I can confirm this for Win7/64 and 64-bit Cygwin on both .34 exp and snapshot
versions of Cygwin library.

Confirmed. I'll investigate.

This sounds like a problem with the parent process holding the event
object connected to the lock. This doesn't happen in the second case,
because the parent holding the lock disappeared as well.

Pity. When I created the locking code I added lots and lots of comments
in the hope that
a) other people would have a chance to understand how the code is
supposed to work and
b) *I* have a chance to understand how the code is supposed to work
after not looking at the code for a year or longer...

Ouch. The handle in the parent got created non-inheritable. That's
bad if the handle is utilized in subsequent child processes which rely
on being able to access the handle.
I applied a patch and created a new developer snapshot on
https://cygwin.com/snapshots/
Please give it a try.
Thanks,
Corinna

Sure, I'd be glad! Only... it's mostly Win32/NT, not Linux code at this
eoint in the source ;)

I should mention that I'm only a grad student with more of a focus in
hardware and computer architecture than softare, so I don't have much
