You would have to change umask in sshd's user's profile to perhaps have
any effect.


I did in the /etc/profile but not sure what you mean in sshd's user's 
profile !


You may want to check the receiving directory DACLs with getfacl .../
and if necessary change them with setfacl -m d:g::r--,d:o::r-- if only
data is being transferred to that directory.


#getfacl samplefolder
#owner :gm-user1
#group :Domain User
user ::rwx
group :: r-x
other:r-x


Yes they only transfer to file in this folder,  if I run setfacl for 
this directory, will it apply to files inside and the file will be added 
later ?


Removing directory DACLs e.g. with setfacl -bk .../ can stop Windows
programs being able to read or write directories or contents.

Get them to set the permissions chmod +r on the source if possible,

they said already give the file with full permission for everyone


and send with scp -p.

Make sure that the directories are all created by Cygwin processes.


Only the folder mounted to home directory created on Windows
as I entered the below in fstab;
E:/SFTP/samplefolder   /home/gm-user1/samplefolder  ntfs 
override,binary,noacl 0 0


so other user try to access to E:/SFTP/samplefolder


 From the top of the device.
Make sure that the directories can be read by group members.

I created SFTP_User group in AD and both of them members

Ensure that the test1 and test2 users are of the same group.
But when I run ls -la on inside the Samplefolder, owner says gm-user1 
groups says Domain Users ,  not sure why it shows Domain users

umask 002 would have done that for you if you'd done it before
creating the file.

It's a bit odd to have +x set on a data file, so if it's not a dll or
exe, you might
want to make it chmod 644 instead.

Avast has put 2 Cygwin files in its chest

[Alex Brega]

Good morning,
a customer of us has big problems with Cygwin and Avast

Infact he has returned his brand laptop bought from us due of it.
The strange thing is a dvd preinstalled file of this Lenovo laptop has been 
succesfully recovered from the chest,but not the 2 files cygwin 
(dbus-daemon.exe and ssh.exe,both in the same folder c:\cygwin\bin).They can't 
be recovered both in the original place and in an external folder as well.I 
have located the chest folder,but it's encrypted.
Would be possible for you to provide me these files (dbus-daemon.exe and 
ssh.exe) via mail or uploaded somewhere in order to recover them on their 
original folders ? 
Please give me a feedback,as soon as possible.

Thanks in advance

Regards

Out of date GNU binutils, and (slightly) broken binutils 2.27

[Franchuk, Alex]

Hello,

I've been responsible for porting a large [primarily] C++ project from 
Linux to Cygwin. This project generates object files at one point in the 
build process which exceed the object file symbol count limit (around 
32k, but if I recall correctly there was actually a binutils bug 
limiting this further to 16k). As such, I needed an assembler and linker 
that supported the windows big-obj format. That was added in more recent 
versions of GNU binutils, however the version that is available in the 
Cygwin repository is discouragingly old. So the first point I want to 
make is to ask whether the maintainers of Cygwin binutils can be pinged 
to update the supported version, or to know why the last supported 
version is from 2014 (is there something that breaks with newer versions?).

The next step I took was to get a recent version (2.27) that does 
support big-obj, compile it on the system, point gcc toward that 
installation, and try to proceed from there. This fixed the big-obj 
issue, and for the most part lots of the sub-projects were working just 
fine. But one sub-project in particular is having an issue: the 
resulting binary (a dll, in this case) has a flaw in the import lookup 
table (.idata subsection). The import lookup table of one 
runtime-dependent DLL is overwriting the null entry that *ends* the 
previous DLL's table. So, the previous DLL tries to link with a symbol 
that is actually contained in the other DLL, while the other DLL still 
correctly points to needing that symbol as well. In other words, this 
makes it impossible to use the resulting DLL, because it has a dependent 
symbol that will never be resolved correctly. It's worth noting that 
lots of other things link correctly without this bug, and other DLLs 
within that file do not have import lookup tables that overrun each 
other. I thought it would be reasonable to send to this mailing list 
because, from what I read in the binutils source, it seemed like most of 
the pe/pe+ code that has been added to binutils was from Cygwin 
developers. I tried to find the root of the problem, but after hours of 
searching and debugging the linker and BFD code, I haven't found the 
source of the discrepancy.

Any advice would be greatly appreciated!

Re: passwd -R?

[Alex P]

I do have cygserver running as "Local System".

My original issue is that cron stopped working after domain user
password reset. Stopped as - it worked fine before.

My first stop was to reset password with "passwd -R", but it did not
fix my cron problem - not running as user (member of local
Administrators group - getting error in Event Viewer), not elevated
("As Administrator").

I suspect some security policies were modified (machine is part of
domain), but I don't know what to check.

Thanks for weighing in.

I am posting here, because just submitted the report to the

the bug, though.  Time will tell if I remember or if anyone there
asks.  :-)

Thank you very much for replying, Andrew. I just reproduced it in
these versions (from `unison -version`):

2.27.157
2.32.52
2.40.102
2.45.28
2.48.3

I will try to post here if I get around to reporting it to the unison list.

Unison 2.43.3 fails to synchronize execute permission bit

[Alex]

When synchronizing two directories on the same NTFS-formatted drive, unison 
(with -perms 0o1777) fails to set execute permissions on new files.  (It also 
fails to detect changes in execute permissions and to set them on existing 
files.)

I am running Cygwin 64-bit from setup version 2.873.  Below is a script to test 
this phenomenon for new files.  It creates and later destroys a sandbox 
directory under /tmp/.

Thank you all for your time and efforts on the Cygwin project.  I have been a 
happy user for over 10 years.

Alex Hankins

This is a simple one... Compiling Ruby on Cygwin came with the following error:

/usr/include/w32api/rpcndr.h:331:5: error: unknown type name
`GENERIB_BINDING_ROUTINE'


Just correct GENERIB_BINDING_ROUTINE to GENERIC_BINDING_ROUTINE.

error: mkstemp was not declared in this scope

[Alex Reynolds]

I am running Cygwin 1.7.27 (0.271/5/3) and g++ 4.8.2. 

I am testing attempts to make temporary files in a POSIX-compliant way, using 
mkstemp().

I get the following error when I compile code that calls mkstemp():

-
$ g++ -Wall -ansi -pedantic foo.cpp
foo.cpp: In function ‘int main()’:
foo.cpp:44:21: error: ‘mkstemp’ was not declared in this scope
-

Here is my code:

-
#
# foo.cpp

#include stdio.h
#include cstdlib
#include unistd.h
#include sys/stat.h
#include cstring

#ifndef P_tmpdir
#ifdef _P_tmpdir
#define P_tmpdir _P_tmpdir  /* MingW */
#else
#define P_tmpdir /tmp
#endif
#endif

int main ()
{
 char const* p = getenv(TMPDIR);
 if ( p == NULL )
   p = P_tmpdir;
 printf(%s\n, p);

 int fd;
 char* tmpl = (char*)malloc(1 + strlen(p) + L_tmpnam);
 printf(%d\n, L_tmpnam);
 printf(%ld\n, strlen(p) + L_tmpnam);
 strcpy(tmpl, p);
 strcpy(tmpl+strlen(p), /sb.XX);
 printf(%s\n, tmpl);

 mkdir(p, 0700); // ignoring return val... mkstemp will fail if directory isn't 
writable
 if ( (fd = mkstemp(tmpl)) == -1 ) {
   fprintf(stderr, unable to create temp file!\n);
   return EXIT_FAILURE;
 }
 printf(%s\n, tmpl);

 printf(%d\n, remove(tmpl));
 printf(%d\n, remove(this-aint-no-file));

 free(tmpl);

 return EXIT_SUCCESS;
}
-

Is mkstemp() part of Cygwin? If not, what options would I have to replace this 
code with equivalent functionality?

Thanks,
Alex

odd installer error unexpected OPENSQUARE

[Alex Garnett]

Hi folks,

I've made a nice Windows port of a client bash installer that
deploys a prepared cygwin distribution using NSIS and runs a few
scripts afterward. Works great on most of the machines we've tested
on, throwing a bizarre error on a Win7 x64 domain machine. Any ideas?

During the Parsing... step:

Parse Errors: \\path\username\Desktop/$RECYCLE.BIN/$RRNEQYK/setup.ini
line 1: syntax error, unexpected OPENSQUARE, expecting $end.

Thanks!

So I'm a bit puzzled where the 1551B change came from, since this is a fresh 
download from mirrors.pair.com.

I picked up source from openssh.org and couldn't see any obvious recent changes 
in ssh-keygen.c.   Obviously there's more to it than that, but I don't have 
time 
to dig further.

Shift Function Key not working because of a bug in xkeyboard-config-2.4.1

[Alex Jodidio]

Please be aware that Shift Function Key (e.g., Shift + F3) is not working with 
xkeyboard-config-2.4.1-1. You can verify that by running xev. 

This problem is known in X11 community and apparently a fix is on its way and 
may already be available in 2.4.1-r2 - see 
http://forums.funtoo.org/viewtopic.php?id=817.

In the meantime you can avoid this problem by going back to 
xkeyboard-config-2.3-1.

fork: child -1 - died waiting for longjmp before initialization

[Freidin, Alex (Alex)]

Hi,
Hope this helps someone and please update the BLODA list. I got an error 
message: fork: child -1 - died waiting for longjmp before initialization when 
running Cygwin GCC 3.4.4 from Eclipse on a new Dell Latitude E6420 and E6520 
laptops with Windows 7 64-bit. Installing the latest Cygwin 1.7 did not help. 
Uninstalling the software listed in 
http://cygwin.com/faq/faq.using.html#faq.using.bloda also did not prove useful. 
After search and trial, I found that it's caused by NVIDIA graphics driver for 
NVS 4200M laptop graphics card. The laptops had version 8.17.12.6696 of the 
driver installed and after upgrading the driver to the latest from NVIDIA 
website (ver 8.17.12.7533) the problem was resolved. 

Thanks,
Alex

few openssh issues

Hash: SHA1


hello friends,

i have just installed openssh with cygwin.

thanks a lot for providing it, and cygwin at general.

however, there are a few issues i found:

1. ssh-user-config fails because of an error in invoking setfacl: o should be
followed by one colon, not two. with one, it works ok.

2. i've previously used copssh, and didn't have to care about user name case
letters, just like windows users. could authentication be delegated to windows?

3. my ssh client was entering a long freezing loop after logout. well i can't
reproduce this anymore, but there's different behaviour (and exit status)
between exiting after issuing no command, and after issuing command(s). ssh -vvv
output is below.

logout, if no command was issued on server during session:

Cygwin (1.7.8 and other versions) problems with globbing when invoked from DOS/Windows with nested quotes

[Alex Khripin]

Hi,

Short summary: getting nested quotes in an argument through to a
Cygwin process from DOS is problematic, and there does not seem to be
any detailed spec for how to escape quotes correctly. Backslash
characters seem to be spuriously generated.

I'm working on a build system (GNU make, Windows build), which invokes
the Cygwin shell to run commands, like so:
sh.exe -c command arg1 arg2 etc

I've run into some serious problems when command is a DOS path (e.g.
c:/qtpath/moc.exe) and one of the arg's is quoted.

Naturally, the problem could be at two points:
1) the Windows code in make could be escaping things incorrectly for
the Cygwin loader to interpret
2) the Cygwin loader does not handle this case correctly.

 A simple test **
I made the following simple Cygwin program, to better show what sh.exe
would be getting from make:
#include stdio.h
int main(int argc, char **argv) {
    int i;
    for (i = 1; i  argc; i++) printf(%d : %s\n, i, argv[i]);
    return 0;
}

-- Normal program name --
c:\cygwin\home\akhripinargs foo 1 2 3 4
1 : foo 1 2 3 4
-- DOS'y program name --
c:\cygwin\home\akhripinargs c:/foo 1 2 3 4
1 : c:/foo 1 \2 3\ 4

As you can see, the second case causes \ escape characters to show up
- and the worst thing, one of them is now escaping a space - so the
above would be further split up as c:/foo 1 2 3 4 -- completely
changing which arguments were grouped together.

 The noglob option **
When I turn on CYGWIN=noglob, there seems to be no way at all to get a
double quote through to the test program - no amount of escaping or
single quotes does the trick. As such, that does not seem to be an
option available to me.

 Is the above a bug? **
I cannot find any mailing list entries or documentation on how quotes
are processed. I looked at the cygwin source (winsup/sources/dcrt0.cc)
and it looks like it enables special processing when an argument
starts with Letter-Colon. I'm sure that's there for good reasons - but
is that processing correct for cases with quotes?

Basically, my question boils down to: is this a Cygwin problem that
can be fixed, or should I pursue a fix to Windows make?

 Correct escaping **
From what I've been able to determine, there is no consistent way to
escape  and \ characters that works both for arguments that are
normal and those that look like DOS paths. If that is the intent,
that's fine - I've been working on a patch for make.

My conclusion is that for escaping normal arguments, the current
approach of turning nested  into  and \ into \\ works fine.

For arguments that look like DOS paths, it looks like the right answer
is pretty complex: enclose the whole argument in  if it is not, then
use '' for  and \ for \; what this does is close the current
double quoted statement, insert the desired character, and resume the
double quoted statement

1.7.7: Mercurial 1.5.4 and Python 2.6.5 conflicts?

[Alex Royo]

Hello list,

I updated Cygwin version 1.7.7, Python version 2.6.5 and Mercurial
version 1.5.4 (the latest versions packaged).

When you run the commands of Hg (Mercurial) that displays the following message:

---
/usr/lib/python2.6/site-package/mercurial/demandimport.py:85:
DeprecationWarning: the sha module is deprecated, us the hashlib
module instead return _origimport(name, globals, locals, fromlist)
abort: No module named _md5!
---

I guess it is packaged for the Cygwin versions of Mercurial that
conflicts with the packaged versions of Python.

Maybe with a newer version of Mercurial correct the problem? Is
posible add a newer version of Mercurial?

Thanks and sorry for my English –that is possible through online translators–

Alex Royo

Re: 1.7.7: Mercurial 1.5.4 and Python 2.6.5 conflicts?

Hi Gio,

 Could you follow the http://www.cygwin.com/problems.html guidelines?

All right, I know very little English and I read a lot of information
leaks. Sorry.

 $ cygcheck -c cygwin mercurial python
 Cygwin Package Information
 PackageVersion   Status
 cygwin   1.7.7-1OK
 mercurial1.5.4-1OK
 python   2.6.5-2OK

I get the same result on my Cygwin installation.

 No such problem. Mercurial is working fine.

I will continue to investigate what is the problem, so you comment
understand that it is a problem of my installation

Thanks and sorry for the inconvenience.

Alex

 The implication from what you wrote above is that you're not the one
 maintaining this mirror.  For obvious reasons, it isn't really feasible
 for the list of official sites to include those that an unconnected
 party suggests or recommends.  If you are maintaining the mirror, then
 you really do need to follow the prescribed way of requesting a mirror
 be added which is found http://cygwin.com/mirrors.html.  Since you

 I can assure you that messages sent to sourcemaster are read by the

 The only option I see that's available to me is to completely

 does not sound fun and I'm hoping someone has a better idea of how to
 remove lots of related packages.


I've also run into this annoyance and I found another workaround you
could try. First, empty the Cygwin package cache on your local
computer. Then run Setup.exe, choosing Install from local directory.
Then you can click on packages to uninstall them without cycling
through the Reinstall option which is what's causing dependent
packages to be reset to Keep.

 Download the Process Explorer and find out who is holding the file open.

Process Explorer is what I used and I made sure absolutely nothing is

 Something has that DLL open/locked.  I suppose it doesn't have to be
 Cygwin but I wouldn't know what that would be.  Any rogue cygwin1.dlls
 on your system.

 To be sure you've excluded all things Cygwin from this install, do a
 'cygrunsrv --list' followed by a 'cygrunsrv --stop service_name'
 where service_name is any service you see listed by the previous
 command.

Oops, I figured out why this was happening and it was rather silly on
my part. I installed cygwin under the Administrator account and was
trying to run rebaseall under a different account. I thought using the
run as administrator option when opening ash would give it enough
privileges but apparently it's not enough. Running ash under the
actual Administrator account made the error go away and solved my
status_access_violation problems. Thanks for the help everyone.

Sincerely,
Alex

DHCP and resolv.conf

Re: DHCP and resolv.conf

[Alex Leigh]

It's not possible to do it with a Windows service that updates
resolv.conf whenever a new DHCP lease is obtained, or, if that's not
possible, a cronjob that periodically polls for new nameservers
obtained from DHCP? I don't know enough about Windows to know if
there's an API for accessing the required information.

  Hi,
 
  Apologies if this has been asked before, but is it possible to have
  /etc/resolv.conf in Cygwin to be automatically updated with
  nameservers obtained using DHCP from Windows networking? Thanks.

Re: Cygwin visual brand

[Alex Leigh]

Why not just use the cyg- prefix, like the cygstart and cygpath
tools already do? Something like cygsetup, cygpackage,
cygpackman, etc. I think these both communicate clearly the purpose
of the program and are short to type.

 Good points

 CygwinPackageManager.exe communicates clearly what the
 program is without any further need of explanation.

 That is a good name. Simple is beautiful.

 Maybe one should also consider CygwinPM.exe. It is less informative but
 there are still cases where short file names are nice to have.

Re: Setup.exe: resets /home symlink to directory when run

 Hello everyone,

  It cropped up just recently on this very list!

  To summarize the outcome of the discussion: use a mountpoint rather than a
symlink.  The mountpoint will overlay (and override) the then-harmless
directory that setup recreates each time.  Plus it's a bit faster than a
symlink :)

Is 256 colors possible with cmd.exe?

[Alex Leigh]

Hi everyone,

I've been using mintty with Cygwin but I'm finding myself running
Windows console programs that don't work with mintty, and it's
sometimes a hassle to juggle two terminal programs. I would like to
try to switch back to the cmd.exe based Cygwin shell, and I can live
without things like termios support, but I need 256 color support for
vim color schemes. So my question is, is it possible to get 256 colors
with Cygwin running on top of cmd.exe? I found something in this
mailing from 2005 where someone said that cmd.exe only supports 16
colors, but I'm hoping that perhaps that has improved in the 5 years
time since, however unlikely it may be.

If this is not possible, then does anyone have any advice on ways to
have compatibility with both Unix terminal features including 256
color and Windows console programs within a single terminal app? The
only solution of this sort I've found is conin.exe from the developers
of mintty. It does provide half the solution in that it allows input
to be piped from mintty to Windows console programs, but unfortunately
it's not possible to see the output from those programs.

Thank you very much for any help.

Setup.exe: resets /home symlink to directory when run

[Alex Leigh]

Hello everyone,

Apologizes if my question is addressed somewhere. I'm new to Cygwin
and I'm uncertain how to research this question further, so I would
like to turn to this list for help.

In my Cygwin installation I've deleted the /home directory and created
a symlink in its place that links to the Windows Users folder, so
that my homedir under Cygwin is the same as my Windows user folder
while retaining the nice and short /home/[name] path in Cygwin. This
has worked well except that each time I run setup.exe, at the end of
the update process the /home directory is restored and the symlink is
removed. It's not a big deal to recreate the symlink each time but I'm
wondering, is there a way to suppress this behavior of setup.exe?
Thanks in advance for any help.

Sincerely,
Alex

Re: Cannot run SSH

[Alex Quinn]

FWIW, I had the exact same problem.  This was under Cygwin 1.5 (not 1.7) and 
Win7 (build 7600 enterprise release).  The OpenSSH server worked for a few days 
and then stopped working with similar symptoms to you.  I eventually got it 
working again.  After working for a couple more days, it broke again.  
Nevertheless, this is what I did to make it work after not working.  I realize 
some of this may be unnecessary or even counterproductive.  I don't know enough 
Cygwin and/or Windows to say what made a difference so I'm just telling you 
what I did in the off chance that it helps somebody find the real problem.

1. Stop and delete the service:
cygrunsrv --stop sshd
cygrunsrv --remove sshd
2. Remove the cyg_server user via Windows.
3. Restart system.
4. From bash, run ssh-host-config to recreate user and sshd service.  Answer 
yes to everything except allow cyg_server to be the name of the user.
5. Manually set the password for the cyg_server user from Cygwin.  Make it 10 
characters with only alphanumeric (i.e. abcDEF1234 - not my password 
obviously).
passwd cygserver
6. Go into Services, properties of the sshd service, Log On tab.  Manually set 
that to the stored log on password for the service.
7. Close bash if it's still open.
8. Start--Run--ash and run the rebaseall command.
9. From the command prompt, run net start sshd.

Please forgive the superfluous details.  Good luck!

Alex

Yep the SYSTEM is listed alright. I already created the passwd file multiple 
times, before and after ssh installation. I do not know what all those numbers 
in it but as far as I can see the users and their default folders listed fine 
there. I can pretty much see all the defined users including the ssh setup 
based users.

mkpasswd -cl  /etc/passwd was the command I have used multiple times.


The weird thing was that the Cygwin+Ssh installation on Win7 was the easiest of 
all installations I had done before. It worked for couple days and stopped 
yesterday. Something is funky and I cannot figure it out after spending 10 
hours on this. I am sure it is couple minutes fix if you are an expert on this 
stuff but that is the best i can do on my own.

matlab not fully functional on cygwin

[Alex D. Kostic]

Hi,

I recently installed cygwin (Cygwin/X X Server Version 1.5.3 (20090222), 
X11R6) and am experiencing problems when I run MATLAB (7.9.0 R2009b)  on 
it.  For the most part MATLAB works fine, except when I open an Editor 
window the contents are blank (it's just a blank box), and when I try to 
open a figure (matlab .fig file) the figure is visible, but the toolbar 
is blank.  So most of the functionality I need with MATLAB is unavailable.


I appreciate any help with this.

Thanks,
Alex

Xterm font resizing broken and input problems in xorg-server 1.5.3-7

[Alex Epshteyn]

I just upgraded my Cygwin distro, and I'm having the following issues
with x-term:

1) cannot input text into any additional xterm window launched by my
start menu shortcuts.  The only xterm window that works is the default
one that comes up when I start x-server.

2) cannot change the font size in ANY xterm window.  Neither by
ctrl+rightclick nor the (newly added) menu bar.  Selecting any font
size from the menu doesn't have any effect.  (Prior to the upgrade I
had the default font set to Huge but now it comes up with the
original, small, default font).

I'm running on Win XP, with xorg-server 1.5.3-7 and xterm 242-1.
Never had any of these problems before this upgrade (my original
install was from March '08).  I'm attaching cygcheck.out for more
details on my system (note: some path variables deleted for privacy
reasons)

The only relevant hit I found on Google is this, which it seems,
describes the same problem (however his solution of appending  -fn
'*12*' to the command line didn't work for me):

Re: Xterm font resizing broken and input problems in xorg-server 1.5.3-7

I realized that there are some startup errors I wasn't seeing by using
the windows shortcut.  Here's what starting xterm on the command line
prints out:

xterm -display 127.0.0.1:0.0 -ls
Warning: Cannot convert string
-adobe-helvetica-bold-r-normal--*-120-*-*-*-*-iso8859-* to type
FontStruct
Warning: Cannot convert string nil2 to type FontStruct
xterm: cannot load font 10x20

I also realized, after some more Googling, that the fonts packages are
no longer included in the distro the same way as before.  I'm trying
to fix the problem by installing all the font-* packages now.  Will
let you know if that worked.

Re: Xterm font resizing broken and input problems in xorg-server 1.5.3-7

Yep, separately installing the font-* packages with setup.exe solved
my problem with the font sizes.  I also haven't seen the no input
problem since, but it was a sporadic issue to begin with, so I don't
know if that fixed it as well.

problems using the setup.exe program

[alex wallis]

Hi list I am fairly new to cygwin and am writing to ask a few questions 
about selecting packages when installing cygwin.


My problem I am facing is this.

I am blind, as a result in order to use a computer I use a program called a 
screen reader. The screen reader allows me to do most things on the computer
such as reading and writing e mails, browsing the net and installing the 
majority of programs.


However there are problems with the cygwin installer. At the moment, the 
setup is useable until the package selection screen is reached. Now it is 
possible

to select to install a hole category such as editors or devl.

However, if I want to go and install only some packages from a particular 
category such as say quilt or subversion from devl it is not possible at the 
moment
to expand these categories and select individual packages using the keyboard 
and some other functions my screen reader has for working with the mouse.


I was wondering, would it be an easy task for the cygwin installer to be 
redesigned to make it more friendly to screen readers? as there are a large 
number
of people who are blind that I no of that use cygwin who face the same 
problem.


As at the moment, unless I can get someone who can see to help me, the best 
I can do is install hole categories of things just to get one package 
meaning

I waste several gbs of space on my hard drive.

Even if it is not possible to redesign the setup program, which I no would 
take time, given the fact I need to reinstall cygwin on my system, does 
anyone
no if it is possible to write some kind of custom setup script or ini file 
that would download only the packages and there dependencies I need to 
install.


As at the moment it isn't that easy for me to get access to sighted help, 
and I will end up wasting several gbs of space just to install a few 
packages.


Thanks very much for your help.

Alex. 

printf goes to serial port?

Hello,

I have a cygwin environment, running some software I am writing to talk

Somehow, trying to debug why I could not see printf output to console, I 
ran a serial port sniffer and voila all of my printf commands are 
writing on the serial port.


Any idea how to fix this?

Re: printf goes to serial port?

[Alex Martin]

Well, I was using a port monitor to debug some of the traffic between my 
serial device, and my software, when I noticed the output accidentally.


I am not sure when the behavior started. It used to work fine, I was 
using printf to debug things, then I turned off all of those printf 
statements, and continued development on the gui side (fox toolkit) of 
my application, and then had to go in and modify my low level serial 
class and was trying to get my printf debug output again, to no avail.


I have updated cygwin a few times, otherwise I cannot think of anything 
specific.


What other details can I provide?

I can't say that it would cross my mind to look for my missing printf output
on a serial port, even if I was using a serial port in other parts of the
program to talk to something.  Whatever it was that gave you the hunch to do
that is probably at the core of your problem.

Well, no, not really, since you've given very few details to go on.  I'd
SWAG that you've somewhere, somehow, redirected stdout to the serial port
you're trying to talk to those devices on.

My slightly wild guess is that you do an open() on the serial device
without a controlling terminal and without passing the O_NOCTTY flag,
causing the serial device to become your controlling terminal.

~Matt


Hello,

I do this:
//snip
if (port == 1) {
   fd = ::open(/dev/ttyS0, O_NONBLOCK | O_RDWR | O_NOCTTY );
}
//snip

Can you point me to some info about controlling terminal? I have been 
living in a strict c++/cygwin/fox-toolkit world and I am not familiar 
with terminals and things.


If I try to run my .exe from a cygwin prompt, it doesnt start up. If I 
run my exe from a cmd.exe window, it starts up my app but then returns 
to a prompt instead of staying open to catch printfs and such.


Any ideas?

Thanks for your help.

Well, whatever details you have.  I'm still in pull mode here, which isn't
conducive to problem-solving.  So far I've been able to gather:

1.  You are developing some sort of app that communicates over a serial port
to some other device.
2.  You have a cygwin environment.
3.  The app has a GUI, using something called fox toolkit (with which I am
not familiar).
4.  You had debug printf()s that used to work, then a bunch of stuff
changed, and now they work differently.

A few gaps that need filling before anything better than SWAGs can come your
way:
- Is this app a Cygwin app, 


No, it is a windows app.

I am using cygwin primarily because I get the /dev/ttyS* devices. I 
could not find info on how to talk to a serial port in the windows world 
without using MFC which I refuse to touch.


or is Cygwin involved only perhiperally (e.g.
you're using Cygwin make to run the MinGW toolchain), 


No mingw. Using all of cygwin's make, g++, etc.

or is Cygwin not

directly involved at all and you're saying My non-Cygwin-related app was
working fine, I changed a bunch of stuff in the app and also upgraded
Cygwin, and now the app is broke and I'm thinking Cygwin could be to blame?


I do not think the app is broken. Somehow stdout is going to the serial 
port, my code relating to file descriptors (a serialio class that 
provides functions like open, close, read, write, flush), opening and 
closing the devices, etc has never changed (that is, the code is the 
same code since back when printf worked). Other code has changed, that 
is, the gui layout, function flow, etc.



- Since your app is a GUI app, where did you expect your printf()s to go?


Well, someone taught me to use cygwin in this manner, and I have been 
doing so for a long time, that is, I can use a cygwin window to invoke 
my windows app, and the cygwin console would catch printfs (stdout 
chatter), so you can use it as a debug console.

PATCH: Re: cygutils/cygstart - wait till task terminates - also pass on exit status

[Alex Smith]

The recent patch sumbitted by Barry Kelly to add an option to cygstart
to have it wait for the process to terminate is most useful. However it
would be more useful still if it were to return the exit status of the
process in this case.

The attached patch implements this small addition and should be applied
on top of Barry Kelly's.

installer is really confusing to use

[alex]

how do I just install a single package? It seems it wants to uninstall
then reinstall everything or some other option I don't want. The closest
I've been able to get is, select uninstall everything, download to disk first,
then install from disk once that's complete but even that is unreliable.

Problem with tags in vim 7.1

[Alex Shturm]

Hello,

I'm having a strange problem with tags in vim 7.1 that I've just installed.
My Cygwin version is 1.5.25-14.

I'm experimenting in directory c:/temp where I have a source file 
test.c and a tag file tagfile (see below).

I also set environment variable EXINIT as set tags=tagfile.

File test.c :


int my_function (int aaa)
{
}



Depending on how the path to the source file is written in my tagfile, 
the command vim -t my_function executes differently :


*** Case (1)
tagfile:

my_function$TESTDIR/test.c/^int my_function (int aaa)$/

Environment variable TESTDIR is defined as c:/temp.
Command vim -t my_function brings vim that reports:

/cygdrive/c/Temp/tes# [New File]
E434: Can't find tag pattern


*** Case (2)
tagfile:

my_functionc:/temp/test.c/^int my_function (int aaa)$/

Command vim -t my_function CRASHES vim (segmentation fault) 

*** Case (3)
tagfile:

my_function/cygdrive/c/temp/test.c/^int my_function (int aaa)$/

Only here the command vim -t my_function correctly loads test.c and 
finds the tag.



Is it a known problem?
Is there any cure for cases (1) and (2) ?
Is there a workaround?

Thank you,
Alex

Re: Problem with tags in vim 7.1

[Alex Shturm]

Corina,

Unfortunately generation of tags is beyond my control. They are using 
environment variables so our source tree could be accessible the same 
way from Unix and Windows (cygwin) machines, where the root environment 
variable is different.


This issue looks like a buffer overflow to me.

Is there anybody willing to take a deeper look?

Thanks,
Alex

I never heard about vim being able to use variables in tags files.
As for case 2, use POSIX paths.

Ctrl-C will not kill a process started from cygwin shell

[Alex Worden]

Hi,

I'm sorry if this is an obvious question but I searched and couldn't
find an obvious answer and wasn't sure what to search for...

It seems that some processes I start from a cygwin shell start in the
foreground - whereas if I start them from a cmd shell they start in
the background. (I know I can append an  but that's not the point
here). One process I know of in particular is my favoured Micro Emacs
editor (available at http://www.jasspa.com/). When this starts in the
foreground from cygwin, even Ctrl-C will not kill the process. What
determines this behavior and can I do anything about it.

I ask because more importantly, I am running into issues running Maven
tasks that do not return to the shell after completion. The only
option available to be is to kill the entire cygwin shell.

Please can someone explain what might be happening here, or point me
at documentation on this subject.

Thanks!

My program restarts six times under Cygwin when run under rxvt/xterm

[Alex Shturm]

Hello,

This is a simple program that I compile as a console application in 
Visual Studio 2005 :

--
#include windows.h
#include stdio.h

LONG WINAPI my_exception_filter (LPEXCEPTION_POINTERS exceptionInfo)
{
printf (*** my_exception_filter ***\n);
return EXCEPTION_EXECUTE_HANDLER;
}


int main(int argc, char *argv[])
{
printf (\n*** SetUnhandledExceptionFilter ***\n);
SetUnhandledExceptionFilter (my_exception_filter);


printf (*** RaiseException ***\n);
RaiseException(EXCEPTION_NONCONTINUABLE_EXCEPTION , 
EXCEPTION_NONCONTINUABLE, 0, NULL);

}
--

If I run this program in standard Windows CMD window, it prints whatever 
it should, and terminates.


If I run this program under CYGWIN, the result depends:
- in standard window (the one that is open by picking Cygwin bash 
shell link in the menu) - the program exits after printing
- if I start rxvt or xterm from the standard window, and then run this 
program in rxvt/xterm window, the program restarts 5 times, each time it 
prints what it should.


Can somebody check my sanity and confirm that this problem is 
reproducible anywhere else?


I'm on Windows XP SP2, all the latest patches, etc.
Cygwin version is 1.5.24 (the latest).

Any help is greatly appreciated.

Thank you,
Alex

Re: My program restarts six times under Cygwin when run under rxvt/xterm

[Alex Shturm]

Christopher,

Cygwin uses the equivalent of SetUnhandledExceptionFilter for its own
purposes.  It can do that because there is no linux version of that
function.

So, if you attempt to use it in a cygwin-aware program, you're in for
problems.  If you need to produce pure windows programs, I'd suggest
http://mingw.org/ .  It doesn't seem like you need Cygwin for the
above.

cgf
  
This small program is just a tiny part of a huge application, which is 
built natively on Windows, and intended to be run without Cygwin by the 
customers.
However we in development use Cygwin extensively, mostly to use the same 
scripts/environment as on Unix platforms (where our application is also 
built).
Hence your suggestion to use mingw is not applicable in our case. Out 
application is not cygwin-aware.


Still something does not look right to me:

(1) Even if cygwin has its own exception handling, how is it possible 
that it interferes with exception handling in my program (which is a 
separate process) ?


(2) Why this issue is not reproducible when cygwin shell is started in a 
regular (cmd?) window, but reproducible only in rxvt/xterm window?


BTW, I've tried running this program under bash, tcsh, and sh, and the 
behavior is the same - that is, the shell is not relevant to this 
problem, only window type is relevant.


It looks like a rxvt/xterm-specific issue.

I wonder if somebody can take a look at it...

Thanks,
Alex

Christopher,

I agree there is a misunderstanding here.
Please see my original post - there I clearly say that I build this 
program in Visual Studio 2005, and not using gcc.


I only have problems *running* it under cygwin.

Thanks,

If it is going to be run without Cygwin then you shouldn't be using
cygwin's gcc.

  
However we in development use Cygwin extensively, mostly to use the same 
scripts/environment as on Unix platforms (where our application is also 
built).



You may be a little confused here.  I'm not suggesting that you have to
wipe cygwin from your hard drive to use MinGW.  For the most part,
Cygwin runs standard windows applications, like the MinGW build tools,
just fine.

  
Hence your suggestion to use mingw is not applicable in our case. Out 
application is not cygwin-aware.



If you are using gcc to build your program then you are building a
cygwin application regardless of whether you use anything from the
cygwin API.  Cygwin is a *dll* it will get loaded automatically when
you start your program and it will do things with exception handling.

Btw, if you build your program with standard cygwin gcc is also GPLed,
which means that you must provide source code for the program to your
customers.

  

Still something does not look right to me:

(1) Even if cygwin has its own exception handling, how is it possible 
that it interferes with exception handling in my program (which is a 
separate process) ?



see above.

  
(2) Why this issue is not reproducible when cygwin shell is started in a 
regular (cmd?) window, but reproducible only in rxvt/xterm window?



Dunno but I'm not particularly interested in finding out.  I know for
sure that if you do what you're doing you will have problems.

  

I wonder if somebody can take a look at it...



It's not likely.  Sorry.  You really should just make your program a
pure windows program.  It will still run under rxvt, bash, etc.  but it
isn't likely that it will manifest this problem and you won't have to
provide your source code to your customers under the GPL.

You can also use the -mno-cygwin option to gcc which will avoid using
the cygwin environment when compiling/linking.  I avoided mentioning
this before because it is a constant source of confusion with people
because it doesn't always work 100% correctly and people somehow think
that it is a way to avoid the GPL but still have cygwin functionality.
It may work in your case but MinGW is cleaner.

Re: My program restarts six times under Cygwin when run under rxvt/xterm

[Alex Shturm]

Wow.
Is it a documented behavior?
What is the reason for cygwin to believe that the program needs to be 
re-run?


I'm not sure how I can control the exit value if the actual exit is 
performed by exception handler...


Thanks,
Alex

Christopher Faylor wrote:

Actually, nevermind.  I know what the problem is.  Cygwin is
interpreting the exit value from your program as being indicative of a
hard failure and trying to rerun it as a result.  If you explicitly exit
with a value less than 65535 it should work better.

See the proc_retry entry.  It neglects to mention that the default is
10.

You might be able to set CYGWIN=proc_retry:1 but it's possible that
Cygwin might still think your program was dying and report that.

This points to some bad interaction with another piece of software on

Did some more investigation - the problem doesn't occur if I edit the
file in CMD.EXE, using the EDIT text editor, nor does it occur if I
edit the file using regular Windows apps like Notepad, WordPad, etc.
A driver problem is definitely a possibility (I'm already suspecting
the NVIDIA nForce chipset drivers), and will look into it.

Some details of my hardware which might help: AMD Athlon X2 4200+
dual-core processor,  Seagate 300MB SATA hard drive, 1 GB dual-channel
RAM, NVIDIA nForce chipset (as noted above), Asus A8N5X motherboard.

I can't reproduce this problem at all.  Assuming nano changes the file
in place, opposed to editors like vim, which recreate the file on write,
then a simple open/write/close like this:

  #include stdio.h
  #include errno.h
  #include sys/fcntl.h

  int
  main (int argc, char **argv)
  {
int fd = open (argv[1], O_WRONLY);
if (fd  0)
  {
fprintf (stderr, open(%s): %d %s\n,
 argv[1], errno, strerror (errno));
return 1;
  }
--argc; ++argv;
while (--argc  0)
  {
++argv;
write (fd, *argv, strlen (*argv));
  }
close (fd);
return 0;
  }

would have the same effect.  It hasn't, at least not in my testing.
Is there a chance that you're suffering from a malice virus scanner?

1.5.21: file timestamp not updated after editing

[Alex Eng]

After editing a file, the timestamp on the file (according to ls -l)
is unchanged.  However if stat filename is executed, the change
timestamp given in the output differs from that given in ls -l:

$ ls -l foo.c
-rw-r--r-- 1 Alex 126 Jul 29 17:10 foo.c
$ nano foo.c
### File is edited and saved ###
$ ls -l foo.c
-rw-r--r-- 1 Alex 289 Jul 29 17:10 foo.c
$ stat foo.c
 File: `foo.c'
 Size: 289 Blocks: 1  IO Block: 1024   regular file
Device: a8dc98beh/2833029310d   Inode: 562949953426654  Links: 1

Change: 2006-07-29 18:19:15.828125000 -0700

This issue doesn't appear to be isolated to ls -l: it is also causing
problems when running make or cvs commit on other files, as make and
cvs thinks that the files hasn't been modified.  (I've resorted to
running touch on the files as a workaround.)

A search on Google on cygwin file timestamp failed to find anything
related. I had deleted my entire Cygwin installation (it is installed
on a separate partition), reformatted the partition (NTFS) and
reinstalled, but the problem is still occurring.  Any ideas on further
diagnosing and solving this problem is appreciated.

I am running Cygwin on Windows XP Home Edition, SP2.  Output of
cygcheck -s -v -r  cygcheck.out is attached.

Thanks.

 If I understand your question correctly, there are at least 4 different

Is there any free source C-code on Cygwin that implements wildcard processing?

fatal error - system shared memory version mismatch detected - 0x75BE0074/0x75BE0096

I've just installed cygwin in default confuguration

This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start-Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

Version of cygwin1.dll is 1.5.19-4

That would suggest that you have to install the rebase package.  Rerun

signal handler and JNI

[Alex Dupre]

Hello,
I have a question about signal handling and JNI under cygwin.

The scenario is the following:
- a cygwin program register a function to handle SIGINT and SIGTERM signals
- the program then launches the Java Virtual Machine via the JNI 
invocation API, telling it to not override any signal handlers


Hitting a CTRL-C should then immediately run the defined signal handler, 
but this is not the case. For some reason (what exactly?) inside the 
java program I need to periodically call a native function linked with 
cygwin, but this is not enough. In the called function I have to do 
something more, like printing a char to stdout or /dev/null (calling 
printf() with an empty string doesn't work). Only in this way the 
signal handler is called as soon as I hit CTRL-C, otherwise it's ignored 
or handled seconds/minutes later.
Maybe the callback to C code is mandatory under cygwin, but why should I 
print something to have to signal handled? Any suggestions?

Looks like some terminfo data is not correct

[Alex Shturm]

Hello,

I'm using latest Cygwin 1.5.19-4.

If my TERM variable is set to either cygwin or rxvt, after I exit 
from VI the contents of the window gets restored.

If TERM is xterm, it does not get restored.
The same behavior is observed in both cmd-based window and in rxvt window.

Looks like a bug in terminfo data for xterm terminal.

Can anybody confirm this behavior?
If this is a confirmed bug, is there a workaround?
Will it be fixed in the future?

Thank you,
Alex

Re: cygwin-1.5.19-2: mkdir returns inconsistent errno

[Alex Riesen]

Eric Blake, Fri, Jan 27, 2006 23:30:40 +0100:
 According to Alex Riesen on 1/27/2006 11:26 AM:
  This was a bit prematurely. There is a big problem with this aproach:
  it changes current directory of the process. So you can't really use
  it in multithreaded or signalled environment.
  So chdir is not a real solution. Is it really that hard to workaround
  the problem in cygwin?
 
 If the Austin Group API set 2 is approved
 (http://www.opengroup.org/austin/mailarchives/ag/msg08954.html), you will
 have mkdirat() that creates directories relative to an open file
 descriptor on an existing directory; that would alleviate the
 non-threadsafe use of chdir().

I agree completely. It just does not help my original problem

Until then, I don't know of ANY race-free
 way to create a directory immediately followed by chdir() or open() that
 guarantees that you used the same directory already made by mkdir().
 Maybe if you call mkdir() restricting the access to just the user, then
 open(O_NOFOLLOW), then fchmod().  What would be cool would be something
 like giving valid semantics to open(O_CREAT|O_DIRECTORY) that acts as
 mkdir(), but I doubt that will happen, either, thanks to current Linux
 semantics (http://lkml.org/lkml/2005/9/24/8).  Meanwhile, you can always
 spawn mkdir(1) and have another process, with no restrictions on using
 chdir(), do the directory creation for you.

It prohibitively unefficient in my case :(

 If it is really that much of a problem for you, you should consider
 raising a defect against the POSIX standard requesting that mkdir() be
 guaranteed to fail with EEXIST on an existing directory, even if EROFS or
 EACCES or EPERM would also otherwise apply.

Which still wont make a portable alternative any time soon.
I'll go with stat(2), including all the problems it has.
Still, it'd be nice of cygwin to follow linux behaviour here.

 This is highly unexpected, does not match linux behaviour
 (it returns EEXIST), and actually breaks git (git clone,
 creation of pathnames, to be precise).
   
Then git has a bug.  Report it there.  To be portable
when making pathnames, you must first check
for directory existance rather than relying on an
errno of EEXIST to tell you the directory exists.
  
   How do you do it race-free?
 
  chdir().  If chdir() succeeded, then the directory existed,
  regardless of the errno that mkdir() reported.
  Take a look at gnulib's mkdir-p.c module:
  http://cvs.savannah.gnu.org/viewcvs/gnulib/lib/mkdir-p.c?rev=1.5root=gnulibview=auto
 
 Very interesting! Thank you for this and the other references.
 I'm given hope! :)

cygwin-1.5.19-2: mkdir returns inconsistent errno

[Alex Riesen]

mkdir (also syscall) return Permission denied when its argument refers to
a mountpoint  at the top of windows drive (probably also a windows mount,
I haven't tried).
For example:
$ mount d: /d
$ mkdir /
mkdir: cannot create directory `/': File exists
$ mkdir /d
mkdir: cannot create directory `/d': Permission denied
$ mkdir /d/tmp
mkdir: cannot create directory `/d/tmp': File exists

This is highly unexpected, does not match linux behaviour (it returns EEXIST),
and actually breaks git (git clone, creation of pathnames, to be precise).

  For example:

  mkdir: cannot create directory `/': File exists
  $ mkdir /d
  mkdir: cannot create directory `/d': Permission denied
  $ mkdir /d/tmp
  mkdir: cannot create directory `/d/tmp': File exists

 I raised this issue before, and the conclusion was that
 POSIX permits this behavior (the mkdir must fail, but
 is permitted to fail for ANY of the permissible errno
 values that apply to the situation when more than
 one failure mode is present).  Therefore, it is highly
 likely that no change will be made to cygwin.

Pity.

  This is highly unexpected, does not match linux behaviour (it returns 
  EEXIST),
  and actually breaks git (git clone, creation of pathnames, to be precise).

 Then git has a bug.  Report it there.  To be portable
 when making pathnames, you must first check
 for directory existance rather than relying on an
 errno of EEXIST to tell you the directory exists.

How do you do it race-free?

No, I don't think it is a bug in git, or in any code which
expects EEXIST from mkdir in case an entry actually
just plain does exist.

 This is not even cygwin-specific.  It is possible on
 Linux to have /usr mounted on a read-only filesystem,
 then /usr/local mounted in a writable location,
 such that the call mkdir -p /usr/local/dir will get
 EROFS on the /usr component rather than EEXIST
 (trust me - the coreutils code for mkdir faced this
 very same issue in 5.90, and was fixed in time for
 the current 5.93).

Are you sure? Linux 2.6.15. It correctly reports EEXIST
on /usr and /usr/local and creates /usr/local/dir.
I'd consider that a bug, if it were otherwise. The reason
of racing alone if enough.

 chdir().  If chdir() succeeded, then the directory existed,
 regardless of the errno that mkdir() reported.
 Take a look at gnulib's mkdir-p.c module:
 http://cvs.savannah.gnu.org/viewcvs/gnulib/lib/mkdir-p.c?rev=1.5root=gnulibview=auto

Very interesting! Thank you for this and the other references.
I'm given hope! :)

Re: Starting with Cygwin NFS Server

 The doc you mentioned above is the README for the original
 nfs-server package.  There is a cygwin-specific README for
 the nfs-server package as well, under:

  /usr/share/doc/Cygwin/nfs-server-2.3-3.README

Thanks.

Perhaps the foloowing question is off-topic.

NFS Client runs on UNIX.
Cygwin NFS Server runs on Windows.


How to specify the device (Windows-directory/folder) to be mounted on
mount point (UNIX-directory)?


The problem is how to set the pathname of the exported file system on
Windows NFS Server.


For UNIX NFS Server the pathname might be set as it follows
IP address of UNIX machine:/dir1/dir2


For instance, Windows machine contains folder C:\folder1\folder2 that
is to be exported.
How to set the pathname? What to do with C:?


Should
IP address of UNIX machine:C:\folder1\folder2
work?
