You can find old mirrors, or use the Cygwin time machine (google for
it.)  But none of these are supported here on this mailing list, as
explained at
, so you're
on your own.

Change to Dwarf-2 debug info.

2006-06-30 Thread Danny Smith

Hello
I thought it was about time to change the default debug info for cygwin
and mingw from stabs to dwarf2.
Currently the default of stabs can be overriden by '-ggdb' (==use the
best format for gdb)  

Apple has done just such a change in gcc 4.2.

GCC 4.3 stage 1 seems like a good time to change the default for mingw32
and cygwin.

Comments?

Back to my room.

Danny

find missing parameter

2006-06-30 Thread prz


I have a small problem with find command
whenever I specify the -exec option this error is displayed

/cygdrive/c/workdir: find  . -name "db*" -mtime +2 -type f -exec /bin/rm {}
find: missing argument to `-exec'

tried quotes - single double ... with/without path to rm or any other
command (ls)
removing the exec returns the correct file

[ANNOUNCEMENT] Updated: bzr 0.8.2 -- Next-generation distributed version control (like GNU arch)

2006-06-30 Thread Jari Aalto


PACKAGE DESCRIPTION
===

Home page: http://bazaar-vcs.org/
License  : GPL

Next-generation distributed version control similar to GNU Arch.

Distributed version control system that is powerful, friendly, and
scalable implemented in Python.

- Just one .bzr directory at the top of the tree; it doesn't clutter
  the tree or get in your face. No wierd ++file--names--0.
- The user interface is simple and familiar to people with experience
  from CVS or Subversion: add, mv, diff, status, commit, log, merge, etc
  all do what you would expect.
- Offers a choice between centralized and decentralized work within a
  single project: when in the office, you can work on a shared central
  branch. For experimental changes or offline work you can make a branch
  on your laptop and merge back in later.
- Preserves history; any previous revision can be recreated. History
  can be GPG-signed to protect against man-in-the-middle attacks, bad
  mirrors, server intrusion or data corruption.

CHANGES SINCE LAST RELEASE

Re: "changed dev/ino" error with NetApp shared drive

2006-06-30 Thread Harald Dunkel

Hi folks,

I would need this fix asap in the official dll. Of course we
tried the suggested snapshot. rm worked as expected, but it
broke a lot of other things, so the snapshot is not an option.

Is there a patch for the existing "official" cygwin package
1.5.19-4, fixing just this problem without putting the rest
too much at risk?


Many thanx

Harri

I've written my own mount command for Cygwin in Perl.  One thing to
be aware of is that drive letters aren't necessary with Cygwin.

You can't say: `cd \\xyz\c$' with Windows cmd.exe.

You *can* say things like: `cd //xyz/c\$' in Cygwin.  This cleans up
many things.  If you have the right permissions `net use' isn't necessary!

A wrapper for `net use' in Perl is pretty easy to do, including all
the password stuff.

Those drive letters just get in the way.  Don't use them.

There's a tiny problem with overlapped I/O which spoils the fun a bit.

2 years ago I had socket I/O implemented using overlapped I/O to get
socket I/O interuptible by signals.  It worked quite nicely, up to the
point where the call was actually interrupted by a signal, the
overlapped call hadn't finshed, and CancelIO had to be called to
interrupt the action.  The problem is this:  There's no way to find
out how many bytes actually were transmitted in case of canceling the
Winsock send() call.

Cygwin's send() could only return -1/EINTR, so the application assumed
that the data has to be completely retransmit and called send() again
with the full block of data.  Out of sync, too bad.

I can easily imagine that we could get the same problem with pipes.
You can argue that the overlapped I/O should never get canceled and
that send() should always return as if all data has been send.  The next
send() then has to wait until the previously started overlapped I/O
gets finished, returning -1 on signal.  But what if the still running
overlapped I/O from the previosuly called send() returns with error?
Out of sync again.

uninstall cygwin

2006-06-30 Thread f g

Hello,


I would like to uninstall a Cygwin installation under
Windows XP: to do this I follow the instruction in 



http://cygwin.com/faq/faq.setup.html#faq.setup.uninstall-all



but I have several problems.

Point 1) I type cygrunsrv -L at Cygwin prompt, but I
get the message
 "bash: cygrunsrv: command not found". What does this
mean? Is it safe to assume that I have non Cygiwn 
services running, and that I can pass to point 2?
Point 2) What is the X11 server? How do I know if
there are any Cygwin programs that might be running 
in the background, and in case there are some, how do
I terminate them?

If I complete these points, there should be no problem
with the following ones: basically, I just
delete Cygwin directory from the hard disk. I didn't
add Cygwin to system path, neither did I set
CYGWIN environment variable, so unless the installer
did it, I shouldn't need to do anything else.
Thanks for your attention,

Greetings,

deltaquattro (Sergio Rossi)

To add another data point:

When running under a public key ssh session, you're running in the login
session of the SYSTEM user.  Also, since you used pubkey instead of
password login, you don't have the credentials for network access.  This
has two results:

- You must use the net command to connect to non-public shares.
- You must use username and password in the net use command.
- You can't use drive letters.

So, what you have to do is this:  Use the 'net use' command with full
qualified domain/user name and password, omitting the drive letter, FROM
INSIDE YOUR PUBKEY SSH SESSION.  This is essential.  You only have to do
this once, in your first ssh session, the connection to the shares is
persistent across multiple sessions as long as you don't reboot.

  $ net use server\\share /user:DOMAIN\\username password

If you don't have a domain, use the name of your local windows box
instead.  However, YMMV depending on the security level used on the
server you're connecting to.

Now you can cd to the share as outlined above:

  $ cd //server/share

In my local environment, I have a tiny script to connect to the servers.
I start it manually after a (re)boot FROM INSIDE MY PUBKEY SSH SESSION.
Additionally I have the matching mount points always defined to access
the shares like local directories:

$ cat ~/bin/calimero
#!/bin/bash
SERVER='\\calimero'
SHARES='cygwinsrc cygwinbin'
USER='CATHI\corinna'

pwd=$1
[ -z "$pwd" ] && read -sp "Password: " pwd && echo
[ -z "$pwd" ] && exit 1
for i in $SHARES
do
  net use "$SERVER\\$i" /user:"$USER" $pwd
done
$ mount | grep calimero
\\calimero\cygwinbin on /home/corinna/bin/cygwin type system (binmode)
\\calimero\cygwinsrc on /home/corinna/src/cygwin type system (binmode)

This way I can just manually reconnect to the server after booting
and then use the shares like local dirs:

$ cd ~/src/cygwin/src/winsup
$ df .
Filesystem   1K-blocks  Used Available Use% Mounted on
\\calimero\cygwinsrc  66168952  38452912  27716040  59% /home/corinna/src/cygwin

Problems building gnuchess

2006-06-30 Thread fabien . hinault

Hello,
I tried building gnuchess on my cygwin box.

./configure gave me the following warning.

/cygdrive/c/Documents: line 1: fg: no job control
/cygdrive/c/Documents: line 2: fg: no job control
/cygdrive/c/Documents: line 3: 5: command not found

I don't know if it is serious or not, and I don't know
how to find if it is serious.
(Is there really a script named 'missing' which is missing? How funny!)

Then, with make, I had a first error:
redefinition of function "getline" .
I renamed the local "getline" into "get_line" in all files, and it was enough.

Then I have another error, at the linking step:

None of this is Cygwin-specific.

First, -exec is a bad way to do this.  It will have to fork/exec a copy
of rm once for each file to be deleted, which is extraordinarily slow
under Cygwin.  Use xargs instead:

find . -name db\* -mtime +2 -type f -print0 | xargs -0 rm

This will result in rm being called only once with all the filenames to
delete as arguments (unless the total length is too great to fit on one
command line, in which case rm will be called as many times as
necessary, but still much less than once per file.)

If you really want to use -exec even though it's horribly slow, then
re-read the find manpage, as you are missing the trailing semicolon that
tells -exec when the argments end.  This makes it possible to include
further 'find' options after -exec without them being treated as
arguments to -exec, for example: find . -type f -exec cmd {} \; -print

Note that semicolon is a shell special character so you have to quote it
if you want to pass a literal semicolon to find, just as you have to do
with * in -name.

Thumbs up from me.  The Cygwin build process is supposed to work

You will encounter many such problems in common unix tools when using a
directory with a space in it.  Unless you really enjoy debugging strange
shell script failures, don't do that. 
. 
Remember that you can use "mount" to translate paths, so there is no
reason why you can't use the same directory as just
/home/fhinault/gnuchess-5.07.

This link command is incorrect.  It is missing some libraries, possibly
as a consequence of configure tests that failed.  First get a
'configure' run that does not show errors, and then if you still have
problems, figure out which library each undefined symbol is defined in
and arrange to include this library in the link command.  The easiest
way to modify this if the configure script gets it wrong is just by
overriding LDFLAGS when configuring, e.g. path/to/configure (configure
options) LDFLAGS="-lfoo -lbar".

Note that the order things are specified on the link command line
matters.  Often linux packages will get sloppy here and it won't matter
because undefined symbols are allowed at link time on ELF platforms, but
not on win32 PE/COFF.  This means it's imperative that the order you
specify things on the link command follows their dependancy chain.

sending an empty UDP packet.

2006-06-30 Thread Tanaka Akira

Hi.  I have a trouble to send an empty UDP packet.

$ uname -a
CYGWIN_NT-5.1 D2RP7F1X 1.5.19(0.150/4/2) 2006-01-20 13:28 i686 Cygwin

I run a UDP server (written in Ruby) on port  as follows
on a terminal:

$ ~/ruby/bin/ruby -rsocket -ve 's = UDPSocket.new; s.bind("0.0.0.0", ); 
loop { p s.recv(100) }'
ruby 1.9.0 (2006-06-08) [i386-cygwin]

I compiled following UDP client on another terminal.

$ cat send.c 
#include 
#include 
#include 
#include 

int main(int argc, char **argv)
{
  int s;
  int ret;
  char *buf;
  struct sockaddr_in addr;

  if (argc != 4) {
puts("usage: send ipaddr port data");
exit(1);
  }

  addr.sin_family = AF_INET;
  ret = inet_aton(argv[1], &addr.sin_addr);
  if (ret == 0) { perror("inet_aton"); exit(1); }
  addr.sin_port = htons(atoi(argv[2]));
  buf = argv[3];

  s = socket(PF_INET, SOCK_DGRAM, 0);
  if (s == -1) { perror("socket"); exit(1); }

  ret = sendto(s, buf, strlen(buf), 0, (struct sockaddr *)&addr, sizeof(addr));
  if (ret == -1) { perror("sendto"); exit(1); }

  return 0;
}

$ gcc -o send.exe send.c

I expect send.exe can send an empty packet as follows.
But the server receive no data.  The server prints nothing.

$ ./send.exe 127.0.0.1  ''
$ ./send.exe 127.0.0.1  ''
$ ./send.exe 127.0.0.1  ''
$ ./send.exe 127.0.0.1  ''

When I use send.exe to send 1, 2 and 3-bytes data, it works
fine.  The server prints "a", "ab", "abc".

$ ./send.exe 127.0.0.1  a
$ ./send.exe 127.0.0.1  ab
$ ./send.exe 127.0.0.1  abc

I can send an empty UDP packet using a mswin32 (non-cygwin)
ruby as follows.  The server prints "".
(The server still runs by cygwin ruby.  cygwin ruby can
receive empty UDP packet.)

$ ~/19/bin/ruby -rsocket -ve 'UDPSocket.new.send("", 0, "127.0.0.1", )'
ruby 1.9.0 (2005-07-22) [i386-mswin32]

But I cannot send an empty UDP packet.

$ ~/ruby/bin/ruby -rsocket -ve 'UDPSocket.new.send("", 0, "127.0.0.1", )'
ruby 1.9.0 (2006-06-08) [i386-cygwin]

Is there a way to send an empty UDP packet from cygwin?

Provided that your version of cygwin (specifically findutils) is reasonable 
recent, you can use


find  . -name "db*" -mtime +2 -type f -exec /bin/rm {} +

to do more or less the same as with xargs.

Thanks for the bug report and especially the testcase.  It's incredible
but the check for a zero length packet has been introduced in 2002, 4
years ago, and nobody has ever complained that it's wrong.  Wow.  Almost
embarrassing.

I've fixed that in current CVS.  Check the next snapshot from
http://cygwin.com/snapshots or wait for 1.5.20, which is really
due soon now.

Thanks for your pointers. Everything I'm wanting to get started is
already covered in the how-to-debug-cygwin.txt.

indications from select(2) interface. But if no worker thread is busy
working on that fd then you get writability back ?

Yes, but it is very hard to get the precise unix semantics. For
example, the application issues a write() which spawns off a thread
that then blocks. Then the application exit()s, causing the thread to
also terminate before completing its write, and the write never
completes.

This is a very valid point, but not one that is a problem in the
situations I'm looking at. The situation I am looking as it much more
chronic.

How does Overlapping I/O get around this, since you have send the data
into the kernel layer and are now waiting on a completion notification
or event signalling. If the application holding the handle exits from
under it, does Win32 kernel abort the I/O in this circumstance ?

What about if this was gotten around via a fork() but not at every I/O
but only if we exit and there is an incomplete I/O operation still in
progress. Can we:

* fork()
* reaquire handle, as per dup()
* CloseHandle() from dying process
* receive IO completion callback with indication of failure, handle
was closed!

* hand data over to the child (of fork()) for it to take up the mission.

Maybe there is a resident part of cygwin that could take up the mission,
since a named pipe can be obtained by any process on the system. This
resident part is a process outside of the lifecycle of the emulated
POSIX processes.

It still would not be perfect but I can't think of any situation that
would use a single write call (as two writes would be allowed to cause
blocking) and the data must reliability make it to the reader, but once
written the writer exited. Pretty rare if you ask me. Even when it was
queued into a POSIX kernel there is no guarantee the reader will read
it, it might sit in the buffer. Applications that need that guarantee
would round trip the other end of the pipe to be sure.

At least we should be able to _DETECT_ that incomplete pipe writing I/O
is still in progress when a process exits. So maybe we can log a
warning and pickup any real problem from there. Rather than thinking
too deeply about that rare case.

There is also the issue of what return value to give the application
doing the write() on the pipe. You'll have to be careful to deal with
error conditions, SIGPIPE, etc, etc.

As cgf put:
| If I understand the plan correctly, in the scenario where select says
| it's ok to write but it really isn't, the write would return as if it
| succeeded and a writer thread would be created which sits around
| trying to empty the pipe.

This is _EXACTLY_ the problem as I see. We have to deal with those
rules, if the OS can't tell us in a reliable way that a write() will work.

The writer thread sits around trying to fill the pipe, would be more
correct.

There maybe other ways to deal with that write() but as far as I
understand the NT kernel does not provide a true non-blocking mechanism
to work from with pipes. This is where you can offer to the kernel the
data and if the buffers are full the kernel will reject the data without
blocking leaving the application holding it. Overlapped I/O as I
understand it does not work like this.

I have read the Overlapped I/O model as documented, but in my (limited)
understanding of Overlapped I/O is that the call to
WriteFile()/WriteFileEx() can still block (and it probably will under
the pipelined conditions of rsync+ssh) when the kernel can't queue new
requests.

I have not read this anywhere but surely everyone can appreciate that an
application can't keep doing continuous overlapped I/O into the kernel
and expect to get back an ERROR_IO_PENDING everytime without it ever
blocking the applications call. Something has to block or the kernel
has to give back another error equivalent to EAGAIN of POSIX. As I
can't see any EAGAIN equivalent I presume it must block where the data
rate of the writer is faster than the reader end of the pipe.

This is not true non-blocking IO as I see it. So there is actually no
non-blocking API unless you use PIPE_NOWAIT, for which there is a big
fat warning not to use. Nature did not intend PIPE_NOWAIT to exist.

As cgf writes:
| The idea of using threads for pipe writing has been bounced around for

I dont see the problem here, each writing process will have its own
worker thread taking the block.

But to pickup with the point here.

  Nope, if you didn't do it, the installer would not have done either.

  And the same goes for cygwin services and X: if *you* didn't set it up, nor
did anyone else.  You should be able to just go right ahead.

gdb: Segfault in pthread_mutex_init


Apparently, the saga of pthreads and buggy gdb continues.

I've previously run into the famous gdb pthread_key_create
segfault on IRIX.  Apparently it exists on Cygwin as well.

But my program also segfaults in pthread_mutex_init:

Program received signal SIGSEGV, Segmentation fault.
0x610af064 in pthread_mutex::init () from /usr/bin/cygwin1.dll

Just like on IRIX, I can continue (many times for this
code, it turns out) and eventually get into a running state.

Is there a fix for this in some soon-to-be-released gdb?

But this is very annoying because the program doesn't

Read the archives, this issue has already been beaten to death.
This is already fixed in CVS cygwin and CVS gdb; but until cygwin
1.5.20 is released, so that a new gdb snapshot can be provided,
you will have to use snapshots or resign yourself to hitting continue.

Okay the biggest factor I overlooked here was that the memory buffer 
inside application space is pinned until IO completion is signalled, so 
the theory here must be that for any real world usage I'd run out of 
application address space before the kernel hit any internal problems. 
As there is little overhead inside the NT kernel per overlapped IO that 
is queued up compared to the 1kb/4kb buffer within application address 
space.


If this is the case then for any application using Overlapped I/O on 
Win32 it must manage its own outstanding queue and perform its own 
throttling to stop it chewing itself to pieces.


But with POSIX in both blocking and non-blocking mode the kernel 
implements that rate limiting by virue of design.


So I think even more that a solution is possible with overlapping I/O 
(after creating a temporary private copy of the application data) with a 
byte count outstanding threshold driving select/poll writability 
indication is the way to go.


If the byte count if over the threshold:
 * When a POSIX write(2) is made on a blocking fd (O_NONBLOCK is reset) 
then we implement the blocking all the way until the IO completion arrives.


 * When a POSIX write(2) is made on a non-blocking fd (O_NONBLOCK is 
set) then we return -1 EAGAIN.


 * Select justs need to lookup the outstanding by count and update the 
write_ready state based on the threshold.


 * The outstanding byte count needs to be protected by a mutex.



If WriteFileEx() can never block for overlapped I/O there is no need to 
have a writer thread.  The purpose of the writer thread then thinking 
out loud before was to offload the possibility of the 
WriteFile()/WriteFileEx() from blocking.  Offloading it away from the 
application thread of execution making the POSIX write(2) call.




Another point I have thought about when we call close(2) on a pipe with 
outstanding IO, we need to close the POSIX side but keep the W32API side 
active until the IO completes.  Call it an unlinked IO if you will. 
This means that the IO completion routine needs to check and handle 
deallocation of the "fhandle_pipe" class since it maybe the last to be 
using it.  Maybe this is already accounted for in some other way.

Yes, that basically means that you have no way of running Cygwin services
(well, technically, some Cygwin programs, notably inetd, know how to
install themselves as a service, but cygrunsrv wouldn't've helped you find
them anyway).  The FAQ could be clearer on this point.

Use "ps -ef" to list all Cygwin processes (from all users).  Again,
probably something for the FAQ.

You'll also want to delete the registry key, as outlined in the above
instructions.  Oh, and deleting the directory won't remove any shortcuts
created by the Cygwin installation packages (like those in the Start Menu
or on the desktop, or the associations created by the "chere" package), so
it's better to use setup.exe to uninstall everything first, *then* delete
the directory and the registry key.

Just to clarify, Igor's procedure won't remove the chere associations

If you don't recognise "chere", then you don't have any associations to

chere -l

To remove the associations, run

2006-06-30 Thread cledford


Hi, much thanks in advance for any and all help anyone can provide.  

I'm by no means a scripting/*NIX/Expect guru - but a while back was able to
stumble  through setting up Windows/CYGWIN/expect enough to put together a
really functional system for basic network management of Cisco routers and
switches.  Everything ran fine on my old laptop which died recently.  I've
just downloaded the latest CYGWIN to my new laptop (I'm assuming a newer
version since last July) and none of my scripts will work any longer.  They
are very basic - essentially they just spawn telnet to a host and do what's
in the script.  It appears that with the current version of CYGWIN (or the
expect that runs in it) the spawn sessions are dying early.  I've scoured
the internet for help, but while there are several people in my same boat -
I'm not finding any solutions.  Attached below is my error message, my
expect script, and my (simple) shell script that pipes in a list of
names/IPs as arguments to expect.

I really relied on this to manage a large number of switches in the past and
am really hurting not having this - thanks for any input at all.

Keeps asking password after putting the id_rsa.pub in ~/.ssh/authorized_keys on remote host

2006-06-30 Thread Tzung-Cheng Yang


Hi,

I tried to make password_less sftp work.

After I putting the id_rsa.pub in ~/.ssh/authorized_keys on remote host, 
the sftp still keeps

asking password.

I also changed the following on the /etc/ssh/sshd_config file on remote 
hosts


RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile  .ssh/authorized_keys

Anything to do to solve the problem?

You didn't mention whether you were using Windows' telnet.exe or
Cygwin's (inetutils) telnet.  (If you had attached the cygcheck output
as per the reporting guidelines this would have been clear.)  You
probably will have difficulty using Windows' telnet with expect as it
does not know about ptys, but Cygwin's telnet should work fine.

Hi Brian - thanks for the reply.  I am using the windows telnet (not by
choice) as I could not find a native CYGWIN telnet app in /usr/bin.  Would
you happen to know what "catagory" the telnet app is and I'll go back to the
CYGWIN website and download?

Here is the output of the cygcheck -c (not sure which option to run - will
go back and look for instructions...)

Anyhow, thanks for the heads up.

Have you tried a recent snapshot?  This may have already been fixed in
CVS, and getting testing exposure will help speed up the 1.5.20 release
process.

ipconfig and cygwin

Please send all queries direct to the cygwin list rather than to
individuals who post to the list.

To find out if a particular package has been ported, use the cygwin
package search page at http://cygwin.com/packages

Doing http://cygwin.com/cgi-bin2/package-grep.cgi?grep=ipconfig does not
reveal a package/file with that name.

That said, ipconfig is a windows command, and I am not aware of an
ipconfig for Unix/Linux.

As I already said in my previous reply, you want the inetutils package. 
And you can always use the package search page on the website.

Aggh.  When you put this inline you just frustrate people trying to
search the mailing list archives because the entire contents will be
indexed and cause keyword searches for unrelated subjects to match. 
This is why the instructions ask you to send it as an attachment.  But
of course you can't attachments because...

2006-06-30 Thread cledford


Sorry to all for skewing the index - in the future is should be made much
more obvious the requirements/process to post a technical question. (I
posted through the web interface and instructions would be nice)

For anyone running into this issue - the problem was the default use (by
CYGWIN) of the windows telnet app.  By downloading and installing the
suggested / inetutils package (located in the - net category under the
package installer) CYGWIN then uses its own telnet app instead.

MEX interface + DAE solvers in Fortran + gnumex/cygwin/mingw

2006-06-30 Thread Hannes Gruschinski


Hi,

I try to make a DAE solver work for my problems using the mex interface
between Fortran and MATLAB. That is, I installed gnumex, Cygwin, and
Mingw according to

http://gnumex.sourceforge.net/

and built the mex interface between fortran and MATLAB 6.5.1.

It turns out that it successfully compiles the test files yprimef.f and
yprimefg.f and runs it.


mex -f mexopts.bat -v -O -output yprime yprimef.f yprimefg.f

This is mex, Copyright 1984-2002 The MathWorks, Inc.
...

yprimef(1, 1:4)

ans =
   2.8.96854.   -1.0947

I then have been trying to compile mex interfaces for RADAU, one of the
ODE/DAE solvers, from

http://www-m3.ma.tum.de/twiki/bin/view/Software/ODEWebHome#ODE_MEXfiles_Homepage

and its solvers from

http://www.unige.ch/~hairer/software.html

Similarly, I have problems compiling DASSL and a test set (Test Set for
IVP Solvers) from

http://pitagora.dm.uniba.it/~testset//instruc.htm

as can be seen below.

I guess it is a problem related to my mex interface configuration.

If you have an idea please let me know.

Thank you!

Hannes

Are you familiar with the Interlocked* family of functions? Depending on 
what exactly you need to do with the value, a mutex may be unnecessary.


Do these function perform buslock prefixed increment/add with memory 
operand.   As per Linux kernel /usr/src/linux/include/asm-i386/atomic.h. 
 Its an atomic add operation that would be needed, but I dont think 
that will be the only thing that will need intra-thread protection.  The 
close() case flag setting might need to be involved too as well as other 
things, like we need serialization.




One point from my last post was:
> Select justs need to lookup the outstanding by count and update the 
write_ready state based on the threshold.


I need to revise that, in that all decrement operations on the 
outstanding byte count need to re-test for the new decremented value 
ends is below the threshold to allow more IO to occur.  If so it should 
_consider_ waking up all threads waiting on the fd under select(2).



That consideration would be along the lines of:

 * If there is blocked IO already waiting behind the serialization gate 
to come through, then this instance of the io completion routine is not 
responsible for waking up select(2).  That responsibility passes to the 
next IO after it has come through the gate and called WriteFileEx() and 
then added its byte count to the outstanding byte count as necessary.


 * If there is no blocked IO waiting at the gate to come through, then 
its the responsibility of this completion routine to wake up select waiters.



This is to stop false writable events from waking up select then we 
already have an IO queued up and blocked.

Right, thanks for the clarification, Dave.  I forgot that chere needed to
be explicitly invoked to add the association (and thus explicitly invoked
to remove it as well).  This also applies to other packages that need to
be explicitly configured (e.g., sshd, cron, etc).

In any case, the advice still applies -- any package that was installed
using Cygwin setup will need to be uninstalled using Cygwin setup to give
the preremove scripts a chance to run.  Technically, the preremove scripts
should undo whatever the postinstall scripts did (if they don't, it's a
packaging bug).

The instructions are at  (just a short
click away from the Cygwin home page, with the link named "Problem
Reports" -- I don't know how much more obvious you can get).  You posted
through the web interface at Nabble (which is not associated with Cygwin).
You might want to do some lobbying for them to include a link to the above
instructions.  And while you're at it, please tell them to allow posting
attachments using their web interface.

The default use is of whatever telnet app is in the PATH first.  That is
not a problem -- that is expected behavior.  The problem was that you were
missing the inetutils package, as Brian pointed out.  You could've
searched for "bin/telnet\b" on the package search page at
, or via "cygcheck -p", to get this
information yourself.

Are you familiar with the Interlocked* family of functions? Depending

Do these function perform buslock prefixed increment/add with memory

 Its an atomic add operation that would be needed, but I dont think that 
will be the only thing that will need intra-thread protection.  The 
close() case flag setting might need to be involved too as well as other 
things, like we need serialization.


Um... probably? Did you try looking at them? There is an 
InterlockedExchangeAdd (I think that's the right name... anyway, you 
feed it a pointer and a constant, and you get back the previous value). 
At any rate, anything Linux can do in assembly, Windows can also do, 
also in assembly, with it's own __asm keyword. The syntax is a little 
different, but it's there, and for something as speed-sensitive as I 
would guess pipes are, this sort of optimization is probably a Good Thing.


Mostly, there is an Interlocked function that will save you from inline 
assembly of most assembly instructions that accept the 'lock' prefix.


Of course, if it can't be done without a mutex in assembly, then it 
can't be done without a mutex, and you remain the person (as opposed to 
me) that knows the answer to that question.

When is next official cygwin net release?

Is there going to be an official cygwin net release soon?  The  
current one is 6 months old, and I could really use an official fix  
for  in order  
to deploy a Cygwin install I am testing.


Also, it would be good if the above bug were listed in cygwin.com/faq/faq.known-problems.html>, and there was a FAQ on the  
Cygwin site with the current estimated release date of the next  
official release.

I chimed in earlier in this thread because I didn't want you to start
working on an implementation which I'd have to reject at some later point.

I just want to be clear here.  I really do want to be convinced that the
current implementation in cygwin can't be fixed before we scrap that and
implement something new.  The person who submitted the original change
thought that it should be possible to fix the problem but he never
followed through with a fix.

Customizing setup.exe (How to specify "default" packages)

2006-06-30 Thread Harry Dellicker


I know this has been asked before but I have not yet found a real answer.

 ---> How does setup.exe "decide" which packages are to be installed by
default?  <---

I do not see anything in setup.ini that controls this.  It is also not
hard-coded in the setup program itself, as far as I can tell, nor does
there seem to be any other obvious external source (file) which provides
the necessary information.

I have seen the suggestion that any packages placed in "Base" will be
included in the default package list, but that seems like a bit of a kluge.

I have spent hours with google, and hours studying the setup.exe source
code without any success.

Does anyone have a answer to this?  Is it just so simple that "any six
year old" could see it, but I'm no longer six?

Thank you,
Harry Dellicker

But those of us who do not use nabble but do try to maintain up-to-date
instructions on the web sites that we manage are not particularly
interested in getting sucked into maintaining descriptions at two
separate sites.

There is a catch-22 here, I guess.  If Nabble really catches on, it
might be necessary to start blocking them just to cut down on people
sending email without understanding the rules.

Maybe you guys ought to read the existing source code before discussing
this.  There are already dozens of calls to InterlockedIncrement,
InterlockedDecrement, InterlockedExchange, and
InterlockedCompareExchange in the codebase, and if you look at winbase.h
you'll see that these have been #defined to be inline assembly versions
of the functions.

That is it.  Setup.exe will automatically select "Curr" for any package
in "Base" (and any of its dependant packages) that is not currently
installed.  I wouldn't say "the default package list" because there is
no list and because it's not just a default, i.e. if you uninstall
something in category "Base" then setup will try to install it again the
next time around.  It's more like "anything in this category is taken as
required and always will be selected for installation if not already
installed."

Simple.  Everything in the "Base" and "Misc" categories is installed by
default.  Any package that an installed package requires is installed by
default.  Shampoo, rinse, repeat.

> I do not see anything in setup.ini that controls this.

You didn't look hard enough.  It's everything with "category:.* Base" or
"category:.* Misc".

Ah, but it *is* hard-coded in setup.  In two places.  See
PickView::defaultTrust() and packagemeta::set_action().

Perhaps, but that's how it is.

It is pretty simple.  And, to answer the question you've put in your
subject line but never asked in the body of the message, the easiest way
to make some packages install by default is to create an empty dummy
package, put it in the "Base" category, and make it require all the
packages you want installed.

Re:MEX interface + DAE solvers in Fortran + gnumex/cygwin/mingw

2006-06-30 Thread James R. Phillips

I receive the mailing list in digest form, so forgive the lack of threading on
this reply.  BTW, good to hear from a Rose-Hulman student (I am an alum).

I think your basic problem is that you don't need cygwin _and_ mingw installed.
 You need one or the other, but not both.  Since the web site you refer to
mentions that cygwin gcc doesn't always work with matlab, I would suggest you
forget cygwin and go with mingw (and msys) all the way.  Try that, and if it
doesn't work, at least your problem is simplified, and it may be easier to find
an answer.  And BTW, you can't post mingw issues here - this list is cygwin
only.

Wnen you have a minute, take a look at the cygwin octave package - it can do
most of what matlab does, and there is even some mex compatibility if you
install octave-forge.

error starting sshd as a service

2006-06-30 Thread Raymond Blum


Hi
 My Win2003 server sshd stopped working last night, from the time of  
day I assume that it was an MS Windows update and in hindsight  
perhaps windows FW had started blocking it and it was reparable  
but... I decided instead to upgrade my Cygwin installation to the  
current release (bad move)


I have it at the point where I can run sshd as the sshd_server user  
("/usr/sbin/sshd -D") but when I start it as a service I get the  
message in the event viewer
"The sshd service was unable to log on as .\sshd_server with the  
currently configured password due to the following error: The  
parameter is incorrect."


I tried, against popular advice in the archives, to run as the local  
system account and turn off privilege separation in sshd_config but  
while the service started I then got the error "seteuid 1003 no such  
process" in the application event log every time I tried to ssh into  
the machine.  So, I abandoned that effort and put it back to running  
as sshd_server.


I have uninstalled, reinstalled, checked the password for the user  
several times.


I have also googled and tried various advice offered on different  
pages for the last 6 hours. So, I decided that it is time to ask for   
help.


Here is what I have from cygrunsrv
$cygrunsrv -L
sshd
cygserver

$cygrunsrv -Q sshd
Service : sshd
Display name : CYG SSHD
Current State : Started
Command : /usr/sbin/sshd -D

I have no idea what parameter it is that's invalid (or even what  
command it is a parameter to) - ie a parameter to cygrunsrv or a  
parameter to sshd.


I have the machine running sshd -D from a session logged in as  
sshd_server but obviously this is not acceptable in the long term.


Thanks for reading this far, any advice or ideas?

Ah yes, it is so simple when someone who knows explains it clearly.  I 
should have asked sooner but was afraid I would get flamed for asking 
something "stupid."


Thanks,

P.S.  Is there any way to get ahold of a copy of the script used for 
creating the setup.ini file?  If not I guess I can simply tack my 
additions onto the end of the official copy each time I rsync my mirror.
