Problem: semctl hangs when waiters are greater than 9
Problem Description:
====================
Objective is to manage concurrent program execution.
c and shell scripting is used.
step 1: semaphore is created (create_sem.c, call made is semget )
step 2: Multiple programs are spawned, they wait on semaphore
(mywait.c, call made is semop )
step 3: Semaphore is removed, so all waiters are fired (trigger.c,
call made is semctl )
semctl() hangs when number of programs (waiters) is exceeding 9.
Instructions to replicate issue on Win 7, Cygwin 64 bit CYGWIN_NT-6.1:
==============================
========================================
Note: for test case you need to have gcc compiler installed as part of
your cygwin installation.
Use may want to use dos2unix to make the c code or shellscript
compile/run if you edited or copy-pasted the code in windows/notepad.
0. create a directory called mytest
1. Create a sub-directory called mywait within mytest.
2. Create trigger.c, create_sem.c, mywait.c and Makefile in the
"mywait" sub-directory.
3. cd mywait
4. make all
cd ..
Description of step 4:
======================
"make all" will compile all the c programs and make executables and
copy back to parent directory (one level up, back to the mytest
directory)
Then you cd back to the parent directory.
5. create a file test_semaphore.sh in the mytest directory using code
provided below.
execute following:
chmod 770 ./test_semaphore.sh
5.5 You should be in mytest directory now.
You should see 4 files - trigger, create_sem, mywait and test_semaphore.sh
6. Following will work without hanging:
=======================================
test_semaphore.sh accepts a single parameter. Parameter is # of
waiters to spawn.
./test_semaphore.sh 5
./test_semaphore.sh 9
7. Following will not work
==========================
./test_semaphore.sh 10
Explanation of step 7:
======================
Once waiters are > 9 all waiters and trigger process hangs.
Running ipcs command also yields same behavior.
Killing one of the waiters (mywait process) will remove the hang and
let process continue.
Google for "cygwin semctl hang" shows few similar threads.
My setup: Win 7, Cygwin 64 bit, CYGWIN_NT-6.1.
Please help shed light on the hang behavior when waiters is > 9.
Thanks in advance for your time, energy and patience.
