[stone cold steve austin]

hi there
i would like to install cygwin as a part of my effort
to have graphic on dual networked monitors. However, i
tried to install cygwin from the following directory

Sure you installed correctly?  I can not reproduce this.

A permission problem with /var/log/wtmp or /var/run/utmp?

Use setup.exe from http://cygwin.com/  That's the only officially
blessed technique to install Cygwin.

Due to your problem report and some googling, I had some vague idea
yesterday, what the problem could be.  But it's not clear if the very
simple patch I applied yesterday does really change anything with
respect to your problem.

Please test the 2006-02-22 snapshot from http://cygwin.com/snapshots/
and report if you see a change, to the good or to the bad.

Distributing Cygwin DLLs with my app

[Dave Bryan]

Hi,

I have an application for Windows written in VC++ which spawns the GNU  
tools GCC, LD, etc. As the GNU programs use the Cygwin DLLs I need those  
also. Is is possible to distribute just the needed Cygwin DLLs with my app  
+ GNU tools rather than the complete Cygwin installation ? There would be  
no cost to customers for Cygwin & GCC, just my VC++ app


Thanks
Dave Bryan

Cygwin Bash shell on Windows 2003 Server not working

[Nitin Agarwal]

I am trying to install cygwin on a Win 2003 Enterprise
Edition machine. I followed all you instructions but was not able to
run the cygwin.

I always get an error in Bash.exe call. My Bash shell is not working.
Any help in this regard would be very helpful. I have included the
content of the dump file created when bash failed to start.

I few points to note:

1. I am using Terminal Services to install cygwin.
2. It is Virtual Machine with windows 2003 installed.
3. I do not see the "sshd" user created on the computer.

I really need to get this thing working. Please help me.

I have gone through mostly all the posts on the internet about this
error and tried all the workarounds but it did not help. I found this
post on cygwin forums, which says cygwin does not work on Windows 2003
server. But there are a lot of people using cygwin on windows.

http://www.cygwin.com/ml/cygwin/2003-01/msg01489.html

I have also attached output of command cygcheck -v -s.

postinstall scripts: .sh and .sh.done

[James McLaughlin]

Hi,

While fixing a problem I'd posted to the group about
(incidentally, thanks to Brian Dessent for identifying
a Cygwin DLL version mismatch as the source of the
other problem), I ran the post-texmf.sh script. I
don't know if this was meant to give me any diagnostic
information, but anyway it ran successfully, which
means (I think) that TEX etc are now installed. (Of
course, until I bring in the Cygcheck output, I can't
really ask about that.)

My real question revolves around the fact that the
script did not change from post-texmf.sh to
post-texmf.sh.done. Should I change it myself now that
it's finished running, or should I leave it be? Plus,
there was another file in \etc\postinstall that was
.sh and not .sh.done - what does this signify?

Thanks,

James McLaughlin.

You have to do it manually - normally this is done by setup upon 
successful completion afaik.


If there's another .sh, then it also needs to be run. They should only 
be .sh if for some reason they didn't run correctly.

Should we start providing /etc/defaults/etc/skel/.Xdefaults, so that new
users can have a sample ~/.Xdefaults to start from in customizing their
use of rxvt?

Try rerunning setup.exe to reinstall bash:

> Not Found: sh

Until that line of cygcheck -svf is resolved, the bash postinstall script
has not correctly run, and cygwin will be unusable.  If you are getting
errors while trying to install bash and rerun the postinstall script, then
there may be some permissions problems to research.  But hopefully the
reinstall of bash will solve your problems.

Re: problem with starting services in 1.5.19

[Yadin Y. Goldschmidt]

I will try sending the attachment again so it will not be encoded.

"Yadin Y. Goldschmidt" wrote in message news:[EMAIL PROTECTED]

I reported this in the past but received no response. Services like cron
and sshd hang up when starting with cygrunsrv in 1.5.29. Upon reboot, most
often one starts
and the other hangs. The problem is best nanifested when from the cygwin
prompt
I type "cygrunsrv -S cron" or "cygrunsrv -S sshd". With 1.5.18 they start
with no problem. with 1.5.19 I get:
"cygrunsrv: Error starting a service: QueryServiceStatus: Win32 error 
1053:

The service did not respond to the start or control request in a timely
fashion"
When looking at ps -a the process cygrunsrv is running but not cron or 
sshd.

Again reverting to 1.5.18 everything works fine. I tried rebase all but it
does not help.
I tried the latest snapshot 20060222 and it does not help either.

Re: script in cygwin

According to the package search page, "script" isn't part of the Cygwin
distribution.

IIRC, "script" is available on cygwin-ports[*], but note that cygwin-ports
has its own support list.  Yaakov did say that he'd be ok with someone
else proposing to maintain it -- are you willing?

IANAL (), but as far as I
understand, the GPL does allow such distribution, as long as you are also
distributing sources for the GPL'd tools.  For further licensing
questions, please use the cygwin-licensing list.

However, it's good that you asked here, because another point of concern
with such distributions is to make sure you don't become a
 by not playing nicely with the existing
Cygwin installations.  As long as your distribution/installer detects an
existing installation and uses its DLLs and tools instead of the ones you
provide (or asks for an upgrade if the tools are too old), you should be
ok.

It would also be nice if you explicitly stated in the documentation that
you use Cygwin under the covers as part of your toolchain, so that
installing Cygwin later will not produce unpleasant surprises.  The best
way of doing this is to install into a standard location rather than the
location of your program (e.g., test for an existing installation, and if
it's not there, install the minimal set of packages in c:\cygwin,
preferably using Cygwin's installer or something with equal
functionality).  That way, if the users later decide to install Cygwin,
your minimal installation will be detected and upgraded.

You can even present this as a choice for the users (like some products do
with things like Acrobat Reader or DirectX) -- if Cygwin is not detected,
offer to install it, and spawn Cygwin setup for doing the minimal install
from your distribution CD.  Fortunately, Cygwin is easy to detect.

Cygwin does not do Unicode, but it does allow (or, rather, doesn't
disallow) native codepages.  For example, I have no problem using Cyrillic
fonts with Cygwin -- you need to use the fonts in the appropriate encoding
for your terminal.

You might find

Re: Cygwin Bash shell on Windows 2003 Server not working

Eric,

Thanks for the reply.

I have run the cygwin install 3-4 times after removing everything. But
I still get the same error. And the installation package downloaded
from cygwin website works fine on one of my Windows XP machine.

You have pointed out an error - > > Not Found: sh

Can I copy this or install this from some other installation package?
Or is there any other way I can install cygwin?

Thanks.

1.5.19-4 mpd crashes when forking

[Pat Kelly]

I can compile and run the latest (stable) mpd, but whenever it would
fork (like if its run as a daemon or mpc tries to play it), it crashes
with:

102 [main] mpd 3796 C:\cygwin\usr\local\bin\mpd.exe *** fatal error -
MapViewOfFileEx (0x13B), Win32 error 6. Terminating.
7 [main] mpd 3704 child_copy: loaded dll data write copy failed,
0x70C05000..0x70C05830, done 0, windows pid 2288260, Win32 error 5


Did I probably mess something obvious with the porting, or is this a
bug in somebody's (cygwin's or mpd's) screw up with the forking?

experimental coreutils-5.94-2

[Eric Blake]

An experimental release of coreutils, 5.94-2, is available to help test
the latest snapshots in preparation for cygwin 1.5.20.  To use this
version, you must have a recent snapshot (20060220 or later)
installed, then use the Exp button of setup.exe to select the
experimental version of coreutils.

This version uses the improved d_ino member and readdir()
improvements that are available in snapshots.  I also intentionally
changed /bin/pwd to use its readdir fallback code rather than
the more efficient getcwd code, so that /bin/pwd becomes a
nice efficient test of whether cygwin is reporting accurate
inode information in its directory listings.  Be aware that
coreutils-5.94-1 does not test all of the code paths of cygwin
like this experimental 5.94-2 does, so I recommend upgrading
coreutils if you plan on testing the latest snapshots to help
look for regressions in file listings.  Functionally, there should
be NO difference in behavior between 5.94-1 and 5.94-2 - if
there is, then you have found a cygwin bug and should
report it to this list.  This includes if the shell builtin 'cd -P'
ever disagrees with '/bin/pwd'.

Well, for my particular hang issue cygwin is hanging inside the

However, this doesn't explain what is happening, but only where.

I also observed that the times it hung were the only times

I'm still trying to get more information.

Due to your problem report and some googling, I had some vague idea
yesterday, what the problem could be.  But it's not clear if the very
simple patch I applied yesterday does really change anything with
respect to your problem.

Please test the 2006-02-22 snapshot from http://cygwin.com/snapshots/
and report if you see a change, to the good or to the bad.


Yeah, I saw that change, and I tried yesterdays snapshot but it still  
hung.  I also did some more googling and found that someone submitted  
a patch a few years ago.  The patch checked to see if it was inside  
the ntdll.dll by looking at the handle.

http://www.cygwin.com/ml/cygwin-patches/2003-q2/msg4.html

I found this google too.
http://blogs.msdn.com/oldnewthing/archive/2004/01/28/63880.aspx

I'm going to try that patch today and see what happens.  Christopher  
didn't apply it because it was a bandage and didn't really fix the  
bigger problem.

apache2 mod_perl

process because file is not installed. (by the way why is default path 
for apache2 not set like in all manuals/howtos in the web? 
/usr/local/apache2/bin/).

can i download this script manually or what needs to be done?

The postinstall script for the bash package effectively does
'cp /bin/bash /bin/sh' from inside a bash shell, so you could
manually do that (or the cmd.com equivalent
'copy c:\cygwin\bin\bash.exe c:\cygwin\bin\sh.exe').  But
the bigger question is WHY the postinstall script is failing,
and the realization that the postinstall script relies on bash
working.  As has been previously suggested on this list,
if you are having problems starting bash, a good thing to
try is opening a cmd.com window in c:\cygwin\bin (or
wherever you installed), then running ".\bash.exe -livx"
to start an interactive login shell with full debugging
statements, and see how far you get or what error
message is printed.

setup.exe is the only recommended method from this mailing

Now released, but it pointed out an upstream bug in coreutils - 'ls -i'
currently stubbornly uses [l]stat(), even when d_ino is available.  So ls
is NOT (yet) a good test of the d_ino changes, after all (but it DOES
remain a good test of readdir() refactoring).

Re: Snapshot report - ssh error

[Karl M]

Hi All...

It was a permissions problem with /var/run/utmp.

But that got me looking...back in Nov 2003, Corinna made the following 
change to ssh-host-config


# Create /var/log and /var/log/lastlog if not already existing

-if [ -f /var/log ]
+if [ -f ${LOCALSTATEDIR}/log ]
then
-  echo "Creating /var/log failed\!"
+  echo "Creating ${LOCALSTATEDIR}/log failed!"
else
-  if [ ! -d /var/log ]
+  if [ ! -d ${LOCALSTATEDIR}/log ]
  then
-mkdir -p /var/log
+mkdir -p ${LOCALSTATEDIR}/log
  fi
-  if [ -d /var/log/lastlog ]
+  if [ -d ${LOCALSTATEDIR}/log/lastlog ]
  then
-echo "Creating /var/log/lastlog failed\!"
-  elif [ ! -f /var/log/lastlog ]
+chmod 777 ${LOCALSTATEDIR}/log/lastlog
+  elif [ ! -f ${LOCALSTATEDIR}/log/lastlog ]
  then
-cat /dev/null > /var/log/lastlog
+cat /dev/null > ${LOCALSTATEDIR}/log/lastlog
+chmod 666 ${LOCALSTATEDIR}/log/lastlog
  fi
fi

And I am curious why set the permissions to 777 on /var/log/lastlog if it is 
a directory?


Thanks,

...Karl

A permission problem with /var/log/wtmp or /var/run/utmp?

Because /var/log/lastlog can be a directory.  In this case sshd creates
files under /var/log/lastlog directory with the name of the user and
each file only contains logininfo records for that user.

We're just missing a lastlog tool which allows examining the lastlog
file(s).  It's part of the pwdutils package from

Problem to launch bash from a shotcut

[Mark Craddle]

I work since years with Cygwin and never found a nice
way to launch a "standalone" bash script from a
shortcut and/or a Windows batch file.

Say I have a directory with :
  bash.exe
  cygiconv-2.dll
  cygintl-3.dll
  cygncurses-8.dll
  cygreadline6.dll
  cygwin1.dll
  my_script(a bash script)
  launcher.bat (or a shortcut)

This directory can be on a cd-rom, an unmapped network
share, a local drive, ...
Then the directory can be :
  D:\mydir\
  \\server\far away\mydir\
  C:\another path with spaces\mydir

It will be nice to just to have to double-clic on
launcher.bat

All I can manage to do is to launch from a mapped
drive.

launcher.bat :
set current_path=%~d0%~p0
"%current_path%bash.exe" "%current_path%my_script"

It is perfect, but only for local or mapped drives.
note : if I use the -c notation I have to use 
"%current_path%bash.exe" -c
"'%current_path%my_script'"

If I try it from a network share I get :
\server\far away\my_script: no such file or directory
Note the single first reverse slash.

I also tried :
set current_path=%~d0%~p0
"%current_path%bash.exe" -c "cd '%current_path%';
./my_script"
but I get the same error on the cd.


Any idea how I can instruct bash to execute from an
unmapped network share ?

sshd, /etc/hosts.allow, & Alternate Access Methods

[Tim Daneliuk]

Is anyone familiar with alternate access methods as they apply to
cygwin? If I edit /etc/hosts.allow, the alternate access method
(indicated by a '+' in an 'ls -l' listing) gets lost. Thereafter
/etc/hosts.allow is no longer properly observed by sshd - it makes ssh
logins impossible from anything other than localhost.

So ... how do I edit /etc/hosts.allow and retain the alternate access
method that appears to be crucial for proper sshd operation?

P.S. Notice that merely copying the originally installed hosts.allow to
 a backup copy causes the alternate access method to be lost:


-rwx--+ 1 tundra None  200 Feb 23 00:15 hosts.allow
-rwx--  1 tundra None  200 Feb 23 00:15 hosts.allow.orig
-rwx--+ 1 tundra None  407 Feb 23 00:15 hosts.deny

Cygwin isn't ACL-aware, and file creation operations don't retain the
original ACLs -- Cygwin constructs them anew to reflect the permission
mapping.  See .
To make sure you keep the ACLs, use an editor that edits files in-place,
rather than making a copy (e.g., vim).

> So ... how do I edit /etc/hosts.allow and retain the alternate access

The alternate access method is not crucial.  What's crucial is that the
files should be a) readable by SYSTEM, and b) not group/world-readable.
To accomplish this, "chown SYSTEM.SYSTEM /etc/hosts.{allow,deny} && chmod
600 /etc/hosts.{allow,deny}" (this is more secure, anyway).  No need for
an alternate method.  You can then temporarily chown them to your userid
or "chmod a+w" for editing (restoring the owner/permissions afterwards).

> P.S. Notice that merely copying the originally installed hosts.allow to

Same reason -- Cygwin isn't really ACL-aware.  You can also restore the
original ACLs by running something like "getfacl hosts.allow | setfacl -f
- hosts.allow.orig" (assuming the owner stays the same).

> -rwx--+ 1 tundra None  200 Feb 23 00:15 hosts.allow

These files should really be owned by SYSTEM (or whatever user sshd runs
as).

To be more precise, Cygwin doesn't support ACL APIs for files beyond what
Windows provides (and those are really outside of Cygwin).  Cygwin
obviously has to be aware of ACLs to construct them for the POSIX
permission mapping.

I probably should've said: Cygwin doesn't "think" in terms of ACLs, but in
terms of POSIX permissions...

Corinna, am I digging myself deeper into the hole here? :-)

Actually, it is more accurate to state that most applications on
cygwin aren't ACL-aware.  CVS coreutils (which will someday
become coreutils 6.0) has a patch currently undergoing
testing that makes cp, mv, and friends ACL-aware, such
that copying a file with ACLs will be able to give the new file
the same permissions.  At any rate, I have not yet had
time to play with those patches to see if they need some
more fixes as part of porting the eventual coreutils 6.0
to cygwin.

However, you are correct that one of the biggest limitations
currently in cygwin's ACL implementation is that default
ACLs attached to directories are not applied to new files
created in those directories.

It may be that vim also needs to be taught to be ACL aware,
and that when editing a file with ACLs and creating a
replacement, it should put the same permissions on the
replacement as the original.  But I leave that to the
vim maintainer to track down.

  That all fits right in with your diagnosis of the problem; a deadlock of
some kind I guess is the only thing that could make GetModuleFileName hang.

  Have you got a stack backtrace showing the call chain when this problem
arises?

  We may be able to come up with a substitute for GMFN that would solve the
problem.

Ahh - that was the hint I needed.  But here is something very strange:

As installed, hosts.allow is owned by the installing user - in this
case, "tundra" who is also an Administrator on the system.  sshd
properly recognizes the rule found in this file.  HOWEVER, if I edit
the file (to change allow rules), I *have* to chown it to SYSTEM or
ssh access outside localhost fails.  Stranger still is that once
the file is owned by SYSTEM, it cannot be further edited because
I get a "Permission Denied" on it with emacs or vi - strange considering
that I am an Administrator on the system.

P.S. Did I mention that I hate the Windows security model ;)

You'd need to decode the stack backtrace on multiple threads, if this is
really that kind of deadlock.

Btw, FWIW, I am excruciatingly aware of this type of deadlock.  I
suffered from it greatly when I moved more of the fork code into the
"DLLentry" part of cygwin to deal with problems caused by Corinna's
streamliing of mmap.

>We may be able to come up with a substitute for GMFN that would solve
>the problem.

Funny you should mention that.  I was just thinking that I could use
either use the technique that gdb uses to find shared library names or
possibly use the stuff in hookapi.cc.  Of course, *that* would be
subject to races.  So you'd potentially be trading races for deadlocks.

Re: script in cygwin

Fedora Core 4 gets this program from a package called "util-linux",
which I guess is roughly equivalent to the cygwin cygutils package.
Certainly it has some contents in common.

Some of the contents of util-linux are already included in official
cygwin packages, and others are not relevant on a Windows platform. But
it does have a few programs that may be useful, including script.

I have a patch for this package that enables building on cygwin of the
following programs as used in fedora core 4:
arch
chkdupexe
hexdump
line
logger
pg
renice
script
setterm
sln
tailf
ul
whereis

I could possibly find time to package and maintain these, as they are
very stable (ie I don't expect there to be much maintenance), if the
cygwin maintainers think they are worth adding to the distribution.
Would it make sense to add these to cygutils, or to distribute them as a
distinct package (util-linux-cygwin?).

Regards,
Steven

bindresvport(): can it be exported from cygwin1.dll?

I see that bindresvport.c is part of the cygwin source code.  Would it be

You have apparently better eyes then I have.  Where did you see that
bindresvport function in Cygwin?

If you're talking about the implementation in newlib/libc/sys/linux/...
then it's unusable for Cygwin.  There's a reason it's in the linux
subdirectory...

>   Would it be

No.  We need a implementation which uses the limited functionality
of WinSock.  It's not that hard, but it's definitely not going to be 
in 1.5.20.  http://cygwin.com/acronyms/#SHTDI

RE: Shells hang during script execution

[Ernie Coskrey]

There are two hang conditions that we've identified and have developed fixes 
for.  This is a description of the first of the two along with a patch; I'll 
follow up with a description and patch for the second.


If a signal can't be handled because it is blocked, it gets queued (on 
the process's "sigq") to be handled later. Now, whenever the process's 
signal mask changes (e.g., the signal in question gets unblocked), an 
attempt is made to handle all the queued signals (i.e., a signal flush 
occurs). However, if the queueing of the blocked signal happens right 
after the signal mask change, then we miss the signal. This causes the 
process to hang. The signal is on the queue, but the process doesn't 
know to check for it. The process just hangs until another signal gets 
sent to it.

The workaround is basically to force the signal queue to be rescanned 
(flushed) whenever we add something to it, so a queued signal is never 
missed.

RE: Shells hang during script execution

[Ernie Coskrey]

Here's a description of a second hang condition we were encountering, along 
with a patch for it.


The application (pdksh in this case) does a read on a pipe, which eventually 
calls pipe.cc fhandler_pipe::read in Thread 1.  This creates a new cygthread 
with "read_pipe()" as the function.  Then it calls th->detach(read_state).

When the hang occurs, the new thread gets terminated early, before 
cygthread::stub() can call "callfunc()".  You see the error message "erroneous 
thread activation".  I'm not sure what's causing the thread to fail activation, 
but the result is, the read_state semaphore never gets signalled.

So Thread 1 goes into cygthread::detach(read_state).  The first thing that 
happens is signal_arrived is set.  The old code would then set n=1, but leave 
howlong=INFINITE.  My change sets howlong=100 in this case.  Then, when TIMEOUT 
occurs, we look to see if __name is not NULL.  Since the thread was terminated, 
its name is now NULL, so it doesn't decrement i, and eventually you break out 
of the loop and clean up as expected.

Thanks for the analysis and the patch.

But, a backwards goto into a case?  Yuck.  I'll see if I can come up
with something better.

Actually, I spoke too soon.  I don't understand your analysis.

You make this statement:

>>However, if the queueing of the blocked signal happens right after the
>>signal mask change, then we miss the signal.

but I don't understand how you came to this conclusion.  If the signal mask
changes, then the queue should be flushed -- that's what the __SIGFLUSH is
for.  So, even if something is added to the queue while the mask is changing,
the function which changes the mask should eventually call send_sig to cause
the wait_sig thread to run the queue.

So, this patch would seem to be a band-aid over some other problem.

Sorry but this is another band-aid around a problem.  The real problem
is that the code shouldn't get into the state that you are describing.
That's why cygwin prints an error message - it is a serious problem.
Making the code deal gracefully with a problem like this isn't going
to solve the underlying issue.

If you can figure out what's causing the erroneous thread activation
then that will be the real culprit.

My script package is based on:

http://www.cygwin.com/ml/cygwin/2002-09/msg01371.html

Which appears to be a (old) port of the util-linux script, but the code
is quite different from the script.c in the current util-linux-2.12r.  I
have tweaked the util-linux script to compile, but it needs further testing.

Actually, after exploring util-linux, it appears that a number of
utilities could be packaged from there, but some of them are duplicated
in cygutils.  Maybe the cygutils maintainer (Chuck?) could step forward
and help explain the similarities and differences between cygutils and
util-linux.

Question about rxvt

[Maurício]

 Hi,

  I've been using rxvt, as recommended by chere man page. I have a 
problem: in some non-cygwin console programs (ghci, the Haskell 
interpreter, and others) the up arrow key doesn't work as expected. 
Instead of repeating the last line, the cursor goes up. Why does that 
happens? Is there something I could read to understand that better?


  Thanks,
  Maurício

You are having difficulties because you don't know how to compile a simple

As installed by what?  I couldn't find anything that generates that file.

That's because it simply checks that a) permissions are no more than 700,
and b) that the file is readable.  Both are satisfied, even though the
owner is wrong.

Thank your editor which makes a copy.  Once you make a copy, Cygwin only
copies the POSIX permissions (which are 700), so that the file is no
longer readable by SYSTEM.  You can use the "getfacl | setfacl" trick to
get the ACLs back.

Why is this strange?  Normally you are not supposed to see files that
belong to other users (and SYSTEM *is* another user).  You can grab the
ownership of the file and edit it, or make it world readable/writable and
edit it.  Just don't forget to change it back to the way it was, or sshd
will complain.

Most of the above is not really due to Windows -- it would happen on any

I'm going to try that patch today and see what happens.  Christopher

bigger problem.


I tried putting the patch in place, and it stopped hanging at the  
place I reported.  I had print statements to verify that it went  
through the section.  However, the program still hung at some point.   
I tracked down a couple of other GMFN calls that used non-null  
handles and tried using the technique that the patch had.


The one at dll_list::alloc caused nothing to run..died with no error  
message.  The second at format_process_maps seemed to work better in  
that the script when running by it self didn't hang.  But when I ran  
another configure script in a different window it did hang pretty  
quickly.  I'm going to look into this more.




  That all fits right in with your diagnosis of the problem; a  
deadlock of
some kind I guess is the only thing that could make  
GetModuleFileName hang.


  Have you got a stack backtrace showing the call chain when this  
problem

arises?

Here is all of the bt's for all of the threads in the program.  If  
you need more information let me know.  But I probably won't be able  
to get it until next week.  My company is moving and things have to

Re: Cygwin Bash shell on Windows 2003 Server not working

[Nitin Agarwal]

Eric,

I tried copyinh the bash as sh.exe by running your command but it did not work.
And when I run .\bash.exe -livx I get the same error in stack dump -

Is there a way reinstall just BASH.exe and run the post install script?

Thanks.

Hi.

Yes, I am pretty sure I have done it right - just unzipped into the cygwin 
directory replacing components of etc and usr if I remeber right
How can I check if it got applied? I mean aside from maybe the timestamps.

Anyhow, you are not the only one who cannot replicate it; so I think it really 
has something to do with windows :(
I will install on another system and test; but cannot till next week.
The guys at the "bug central" emailed me back on my bug submit, and they cannot 
replicate it either.

There's not many cases of this happening, so I assume it's something weird

Oh well... I got a workaround that allows me to do what I need, and if needed I 
can just wait and see what happens in the next release.

Thx for trying to help though.

GT

Does the latest snapshot behave any differently?  It has a temporary
patch which stops cygwin from suspending (for long) when the current IP
is in the cygwin DLL itself.

Perl NET::SERVER module acts strangly in cygwin

[Bruce Dobrin]

HI All,
Perhaps this is the wrong list for this,  but as it is Cygwin
specific...
Anyone have any experience with the perl NET::SERVER module?
I have been re-writing some of my perl servers using the
NET::SERVER::PREFORK  (v.90)module.  All is well on Linux but in Cygwin
(1.5.18) everything works fine until I try to take the data coming in
via the socket ($_)  and fork off a "system" or "exec" using that data.
When I do this,  the client connection is abruptly closed without
successfully performing the "system" call.  If I define the variable
internally it all works fine. 

Example:
Sub make_dirs (
 my $destinU = $_ ;
 chomp;

  $destinU =~ tr#\\#/#;
  $destinU =~ tr/://d;

  print "unix style destination is $destinU \r\n";
 
  if (! -d "$destinU" ){
print   "system \"mkdir -p ${destinU}\"\r\n";
   system "mkdir -p /cygdrive/c/${destinU}" ;

Result:
unix style destination is c/temp/newdir
mkdir -p /cygdrive/c/temp/newdir

#And nothing happens and client session crashes.

If I set the above second line to : 
my $destinU = c:\temp\newdir ;

I get :
unix style destination is c/temp/newdir
mkdir -p /cygdrive/c/temp/newdir

 the directory is created and the client session remains open and
stable.

If I run the first example on Linux (centos4) All works as it's suppose
to and I get weird /cygdrive/c/temp directorys ;)

I tried running the above example in a script using the SOCKET module,
and the above worked as expected .

I've been staring at strace logs,  but I'm not getting anywhere...

Any help or suggestions would be appreciated
Bruce D.
