Johan,

Your UID is greater than 65536 (which is the limit for 16-bit uids).  You
can do one of two things: (1) edit /etc/passwd and change your UID to
something else (yes, you can do *that*); 479 should do just as well as
anything else, as long as does not belong to any other user in the passwd
file, or (2) upgrade to the *experimental* version 1.5.1 (or is .2 out
already?) that uses 32-bit UIDs.

What is with the selective reading style in this thread?

I saw that a referenced LGPL license is unacceptable for cygwin.

Gerrit responds with a pointer to a BSD licensed version.  Asks if
it is acceptable.

I say probably but you'd have to ask the newlib mailing list.

Nicholas responds eight hours after this interchange.  He opines that I
probably don't know about the Red Hat employees who run the glibc
project and offers that somebody should find a BSD licensed version of
ftw.

Now, a day later, we find that Gerrit's email has again been ignored
and the Wourms plan is unworkable.

Odd.

May be I was mistaken and I was thinhing to another problem, but I'm
definitively not the only person who have notice a problem when running
cygwin.
Check the threads around:
http://www.cygwin.com/ml/cygwin/2003-03/threads.html#01510
(about fork and ressources unavailable and jamming cygwin in 10 minutes)


Why are you playing dumb and denying some of us see the problem only
with cygwin ?

BTW, I respond to a remark from Christopher. Yes, probably other
programs are affected by this bug from Windows (/some of its functions).
But I haven't noticed any clear indication in this direction. 
However I have no doubt there is a problem the 100th time I run my
bash-wrapper (that launches gVim), or when I try to compile GNU program
like mutt -- I need to reboot three times and delete lines already
executed if I want to have mutt-1.5 with some specific patches.
So far, cygwin is the ultimate "developer" for this bug.

I'm asking a workaround to another party code used by cygwin. If I know
that a particular function (from a third) is buggy/non portable, I won't
use it in my code, or at least, I'll try to be sure I use it under the
best conditions.
Unfortunatelly, it seems nobody knows which third party function is
buggy in that particular case.

I'm doing approximatelly:

tar xvf mutt-1.5.1.tar.gz | gzip -cd -
cd mutt-1.5.1
./configure
make

But what will be more interresting is: what is installed on the
system/how the system was installed. Because if some people are not
seeing the problem, it means THERE IS a solution.

If ten people are experiencing the problem, it worths fix it. Because
what the ten people will first think is: "damn! cygwin is buggy and
cannnot fork anymore". You and I know it's untrue. The unfortunate new
user of Cygwin won't.

We don't feel the same. When I program a() that uses b(). If b() is
buggy under certain condition, i usually try to find/program b'() that
will ensure that my a() will always work as expected. That's _my_
responsability to use 3rd party code/library/API that works correclty.

May be there is a b'() in that case, may be not. I don't know yet. In a
month or two, I'll try to remember how gdb works and check this out --
I'll probably need assitance from people not having the problem as I'm
not able to compile big program.

By the mean, time I have some open-source stuff I've developped to fix
before unhappy users ask for refund.
And by an hour or two, i'll check if RAMpage is of any help.

Re: proftpd issues

[Igor Pechtchanski]

Fixes for what?  If proftpd needs to switch user contexts (using Cygwin
system calls), the account it runs under needs to have those rights.
Period.  If the SYSTEM account doesn't have those rights on your machine,
it's nothing that proftpd can fix.  You'll just need to either create an
account with those rights, or add them to an existing account.

As for domain authentication, are the entries for the domain users you're
trying to authenticate present in your /etc/passwd file?  Are their
corresponding groups in /etc/group?  Just to eliminate that possibility,
could you please run "mkpasswd -d yourdomain >> /etc/passwd" and "mkgroup
-d yourdomain >> /etc/group" before trying again?  You may want to save
backup copies of /etc/passwd and /etc/group first.

I would be inclined to binary mount it for everyone

mount -s -b c:\\program\ files\\cygwin\\tmp /tmp

If you must stick to a directory path with spaces in it might be better
to use

mount -s -b c:\\PROGRA~1\\cygwin\\tmp /tmp

If c:\program files\cygwin is your cygwin / then

mkdir /tmp

may be an easier choice.

As for trying to help, well AFAIK, it is impossible to get perl to debug 
under gdb on WinME since one of two things happen:

1)either you try to run perl inside gdb, which promptly locks up the 
machine.

2)you try to get gdb to catch the process when it segfaults, which again 
is useless since it locks up the machine.

No offense to Jason, but rebase is really just "papering" over a much

that "rebase all" only takes into account the dll's installed by the

named ".dll" (like in Ruby which leaves them named *.so).  It also
won't take into account user-installed dlls or perl modules.  I've
managed to work around this on my Win2k machine by modifying rebase
all to use `locate` and to run rebase on any ".so"'s it finds in the
Ruby dir.


If rebase and rebaseall don't meet your needs, then supply the patch(es)
to enhance them so they do.
Unfortunately, I have no patches to supply.  Using find/locate is rather 
sub-optimal and probably isn't the way to go.

However, one partial solution would be to rename the ruby .so's to 
.dll's in the buildscript.

But all the rebase patches in the world aren't going to "really" fix the 
problem, since the problem lies in the heart of Cygwin, not rebase.  I 
think I'm just going to quit trying to argue this now, since people 
obviously aren't interested in discussing it (not that my reply to 
Gerrit's flame even intended to do so).

Rodrigo,

I will try to spend a little time looking at this, but it's highly unlikely
that I'll be able to duplicate the problem because 1) I don't have the same
printer, 2) I don't have access to any machines running Win95, and 3) I don't
have access to any locally-connected printers.

I'd be interested to know if using "Printer Name" instead of lpt1 as the device
works any differently. In other words, if the name of your printer in the
Printers applet of Control Panel shows as "HP-Deskjet 670C", try using the
command

lpr -l -P "HP-Deskjet 670C" file.prn

to spool your file and see if it makes any difference. The code that allows lpr
to access devices like "lpt1" is experimental, at best, because I have no way
to test it due to item (3) above. The other items I would be interested in are
1) output from lpr when used with the -D flag (adds debugging printout) when
the device is lpt1, and 2) the actual contents of your file.prn, preferrably
archived and compressed.

Hi Larry,
Sorry about the confusion, I've never had to set this before, and I thought
that you meant the bash environment.  Your suggestion worked, but only when I:
   set CYGWIN tty

... in the .bat file I use to start the cygwin bash shell (cmd.exe).  If I set
this same environment variable in my windows environment (settings ->
control_panel ...) it didn't work.  Interestingly enough, either way I set it,
it did show up as being set in my bash environment once I started the shell. 
But I'm not sure why one way works over the other.

Anyway, I'm happy your suggestion works; no more Ctl+C killing my ssh
sessions.   Thank you very much.  Maybe we can end this rediculously long
thread now!


Glad to hear this works.  Setting 'tty' in CYGWIN from the control panel
should work as well.  That's the way I do it.  So there's something a
bit fishy there.  But, no matter (for you) I expect.  I am still surprised
that it's dependent on the server you log into, all things considered.
I'm fine with leaving that as a mystery for another day though.

So i modified the Cygwin.bat , replacing "bash --login
-i" by "tcsh -l -i" ...
But when i run Cygwin, it shuts down immediatly.

Why please ???

I came up with a different hack to get it working enough for my
purposes.  After reading the thread Chris mentioned, I don't think
I'll submit those changes as a patch.

Enabling malloc debugging did allow me to find the source of the
heap corruption that was breaking tar.  I'll submit the patch to fix
it shortly.

RE: Unable to bring up netscape as any other user

[Menon, Girish (MED, WIPRO-GE MED)]

I am not getting any error at all from the execution of the script. It
just quits. I checked the error code too. It is 0.

I also tried with giving the entire path, like /bin/env. That did not
work either.

BTW, as I mentioned before, cygrunsrv has the -i/--interactive option
that
allows you to set this from the command line.

FYI, backtick processing does not happen in the background -- the
spawning
shell actually waits for the child to complete.  That said, what are the
exact errors you're getting when you try to execute that script?  Keep
in
mind that your environment (in particular, $PATH) may not be the same in
the spawned process and the interactive shell.  Try fully specifying the
paths to any commands ("env" and "grep" in your example).

Ok.  Interesting.  I know what the problem is.  Should be "easy" to fix.

Sounds like we need a 1.5.2.

You've installed some test packages but you're not running the test
cygwin package.  Rerun setup, make sure you *don't* change the default
"Curr" to "Exp" and let it install anything it needs to.  Try it again.

I would give you the "less" version number , but "rpm -q less" gives :

$ rpm -qa
error: db4 error(13) from dbenv->open: Permission denied
error: cannot open Packages index using db3 - Permission denied (13)
error: cannot open Packages database in /var/lib/rpm

Doesn't anything work in cygwin  ? :-)


No, nothing does.  You shouldn't use it.  Try Windows apps and O/Ss.
They _always_ work.
Did you install 'less' via 'rpm'?  If you did, you want to inquire at the
site that provided 'less' as an RPM file for assistance.  If you did not
install 'less' via 'rpm', why are you surprised that it's not in the
RPM DB?  BTW, 'cygcheck -c less' always provides package version
information if you install via setup.exe.

"mobile" cygwin

[Bogdan Czyz]

Hi there,
I'm trying to create custom cygwin build (about 40MBs). I mean I'm trying to 
collect most of shell and file tools, and have at least cygwin sshd working. 
I'd like to have everything on cd and when needed copy all cygwin directory 
structure to hard disk (not only my private pc's disk but pc's disk I work 
on that day - I don't want to install cygwin on each pc I got to work on) 
and run all the utilities and use for instance sshd for port forwarding.
I'm in half way. I got all utilities working in place, batch files to add 
and remove registry entries for cygwin (to get proper mounting points from 
bash). Last thing I can't figure out is sshd. To be more specific passwd. 
I'd like to have one (or couple) user(s) that I can work with independently 
of system. I'd like to run sshd on machine I work on and I wouldn't like to 
worry about creating new /etc/passwd each time. I'd like to use one of 
defined users with known password and do what I need to do. Is that possible 
at all with cygwin?? user independently?? If you have any ideas, please 
advice.

Thanks in advance,
Bogdan

Having had some experience with this, I find it highly doubtful that any

If someone wants to fix this then researching the Microsoft Knowledge

Could it be *possible* that cygwin leaves some memory allocated?  Does 
windows claim to free all memory allocated by a process when it exits? 
What about cygwin shared memory?

I'm not claiming it's a cygwin problem, I'm just curious.

RAM
(it was top spec. at that time!) - I installed W2K just recently. (Now w
256MB)

 The first 2-3 years it was turned on, all the time - running the first
"distributed.net" projects. At least three times a week I had to restart
windows, simply because RAM was all wasted. As I later concluded - it was
vcache (i.e. disk buffering) that filled up RAM to the extent that there was
NOTHING left for application use - at this point all memory allocations lead
to EXTENSIVE swap file use.

 IMO this behaviour was/is very prominent in W98. I found a remedy though...
first running a sibling to RAMpage, then by fiddling a bit with
"system.ini" - see below.

 This little addition to the ini-file has held the machine very much more
usable, with just a little more disk-thrashing as side effect.

 I wouldn't be too surprised if there STILL is something like this left in
more recent Windows versions.
If there is a this easy remedy for them is beyond my knowledge.

 So, cgf is right here IMO.



HOWTO, FYI:
 I have kept maxfilecache (KBytes) at 10-20% of installed RAM and chunksize
(Bytes) as high as I have considered reasonable.
 i.e.
   a) maxfilecache/chunksize should be a fairly high number. (better
cahche-ability)
   b) chunksize shouldn't be _too_ small. (too small -> overhead grows)

 Please note that I have NOT done any benchmarks here...


-- system.ini - addition/change for 256MB RAM --

[vcache]
maxfilecache=40960
chunksize=2048

Re: Win2k and cygwin memory leak

Forgot to add that I call the perl script every *FIVE* minutes - 24-7. 
The script is VERY memory intensive so it really works cygwin and the 
2000 Server HEAVY. If I didn't scrub the memory four times a day, the 
box would crash - and did just recently when I had turned off RAMpage 
for testing.
Running a very memory intensive process every 5 minutes seems wasteful 
to me. Why not make the very memory intensive process a daemon and write 
a very memory light client to query it?

Also, I may be naive or idealistic but I don't think that running out of 
memory should ever "crash" a system (depending on your definition of 
crash) rather it should either grind to a crawl or new processes should 
fail with out of memory errors. It is really crashing your 2000 server? 
If so who do you think is really responsible for such an (here's a clue) 
OS failure?
