Bug: cp fails to treat foo as foo.exe (1.5.5-1)

2003-10-08 Thread librik

SUMMARY:
In the latest version of Cygwin (1.5.5-1) the cp command has stopped
aliasing .exe files (e.g. foo.exe) to their .exe-less counterparts (e.g.
foo).  An odd error message is printed instead.  This is documented to
work.  (cf. http://cygwin.com/cygwin-ug-net/using-specialnames.html )
This feature worked correctly in earlier versions of Cygwin, e.g. 1.3.22-1.

HOW TO REPRODUCE:
   Download, install, and start Cygwin 1.5.5-1.
 (My system: Windows XP SP1.  DOS-type newlines selected in Setup.
  Default shell is bash.)
   Execute the following commands:
  mkdir foo
  touch foo/bar.exe
  cp foo/bar bar
   See the error message:
  cp: 'foo/bar' and 'bar' are the same file

WHAT IS EXPECTED:
   bar.exe should be copied to the current directory.
   (This is what happens in Cygwin 1.3.22-1.)

Hope you can get this fixed for the next release.

Thanks,

- David Librik

Is a function actually inlined?

2003-10-08 Thread Alex Vinokur


Windows 2000 Professional
CYGWIN_NT-5.0 1.5.4(0.94/3/2)
GNU gcc version 3.3.1 (cygming special)
GNU nm 2.14.90 20030901
GNU objdump 2.14.90 20030901
===


How can one know if a function requested to be inlined is actually inlined?

Here is an example.

Are the foo2() and foo3() functions actually inlined?

== 1. C++ code : File t.cpp : BEGIN ==

struct Foo
{
  void foo1();
  void foo2() {} // requested to be inlined
  void foo3();
};
void Foo::foo1() {}
inline void Foo::foo3() {} // requested to be inlined

int main()
{
Foo ins;
  ins.foo1();
  ins.foo2();
  ins.foo3();
  return 0;
}

== 1. C++ code : File t.cpp : END 


== 2. Compilation : BEGIN ==

$ g++ -save-temps t.cpp

== 2. Compilation : END 



== 3. Analysis of the t.s file : BEGIN ==

$ grep foo t.s

.globl __ZN3Foo4foo1Ev
 .def __ZN3Foo4foo1Ev; .scl 2; .type 32; .endef
__ZN3Foo4foo1Ev:
 call __ZN3Foo4foo1Ev
 call __ZN3Foo4foo2Ev
 call __ZN3Foo4foo3Ev
 .section .text$_ZN3Foo4foo2Ev,"x"
.globl __ZN3Foo4foo2Ev
 .def __ZN3Foo4foo2Ev; .scl 2; .type 32; .endef
__ZN3Foo4foo2Ev:
 .section .text$_ZN3Foo4foo3Ev,"x"
.globl __ZN3Foo4foo3Ev
 .def __ZN3Foo4foo3Ev; .scl 2; .type 32; .endef
__ZN3Foo4foo3Ev:
 .def __ZN3Foo4foo3Ev; .scl 3; .type 32; .endef
 .def __ZN3Foo4foo2Ev; .scl 3; .type 32; .endef

== 3. Analysis of the t.s file  : END 



== 4. Use of the nm utility : BEGIN ==

$ nm -C t.o

 b .bss
 d .data
 t .text
 t .text$_ZN3Foo4foo2Ev
 t .text$_ZN3Foo4foo3Ev
 T Foo::foo1()
 T Foo::foo2()
 T Foo::foo3()
 U __main
 U _alloca
0006 T main

== 4. Use of the nm utility : END 




== 5. Use of the objdump utility : BEGIN ==

$ objdump -CS t.o | grep foo

 :
  2a: e8 d1 ff ff ffcall   0 
Disassembly of section .text$_ZN3Foo4foo2Ev:

I think you must use smoe level of optimization to get inlines:

from "man gcc":

  -fno-inline
  Don't pay attention to the inline keyword.  Normally this 
option is
  used to keep the compiler from expanding any functions inline.
  Note that if you are not optimizing, no functions can be expanded
  inline.

  -finline-functions
  Integrate all simple functions into their callers.  The compiler
  heuristically decides which functions are simple enough to be 
worth
  integrating in this way.

  If all calls to a given function are integrated, and the function
  is declared static, then the function is normally not output as
  assembler code in its own right.
  Enabled at level -O3.

Yeah, that's where I got the idea for the code I posted -- since it
was a) not obviously still available from the author and b) much more
sophisticated than I required, I posted the simplified version.  For
the full deal, it's certainly the right thing.

As another poster pointed out, this is just a workaround, the main
goal is figuring out how to help the xemacs developers fix this in
their cygwin build . . .

[ANNOUNCEMENT] Updated: ash-20031007-1

2003-10-08 Thread Corinna Vinschen

I've updated the version of ash to 20031007-1.

This version now uses access(2) to find out if a command given with
absolute path is executable.  That should solve issues with setup.exe,
where some of the scripts in /etc/postinstall are not executed.


To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page.  This downloads setup.exe to your system.  

If you have questions or comments, please send them to the Cygwin
mailing list at: [EMAIL PROTECTED] .  I would appreciate it if you would
use this mailing list rather than emailing me directly.  This includes
ideas and comments about the setup utility or Cygwin in general.

If you want to make a point or ask a question, the Cygwin mailing list
is the appropriate place.

I'd consider this off topic for this mailing list ...

But in the most recent gcc's -Winline will give warnings whenever an inline
request is not followed.  This flag exists in a multitude of gcc versions,
but only started working correctly recently.  (I don't remember which
version offhand...)

If it's a C++ DLL, there are some issues with name mangling, IIRC.
Otherwise, you simply declare the functions as you normally would and
supply a "-lCOM" flag to the linker (provided your DLL is named "COM.dll";
you may also need to add a "-L" flag pointing to the DLL's directory).

In a more complex case, I believe you can use "dlltool" to create an
import lib (COM.dll.a).  Read up on "dlltool" for details, and see, e.g.,
Cygwin source code for some examples.

Hello,

I miss that option.

On Solaris it works with CC and g++ well.

I'm using gcc version 3.2 20020927 (prerelease) on cygwin.

Is this option left off by intention or is this an error?

Lost and Found: cygpcre-0.dll

I just installed cygwin using setup from the website, but when I tried to

to cygpcre-0.dll seems to solve the problem. Perhaps there is some problem

A quick perusal of http://cygwin.com/packages/ shows that the cygpcre-0.dll
file is located in the libpcre0 package.

I've just verified that this package is pulled in by default when you
install less via setup.exe (Install From Internet option).  Copying
cygpcre.dll to cygpcre-0.dll is not the correct solution.

How can one conclude if a function is actually inlined on the basis working with  the 
nm and objdump utilities?
For instance, are 'the foo2() and foo3() function from my original posting' actually 
inlined?

I'm sorry but I can't help.  I have no clue why Winsock on your machine
returns that error.  Just to be sure, you did use and change the services
file in ${windir}/system32/drivers/etc?  And did you check if that file
is readable for Everyone?

The general rule of thumb is: if there's a call to a function, it's not
inlined.

FWIW, it doesn't look like they are inlined.

setup hangs during postinstall

2003-10-08 Thread Steve Kelem

I'm trying to update to the latest cygwin (1.5.5-1). Setup install a lot 
of things, said I had to reboot, and then proceeded with the postinstall 
step.
Setup is stuck, with the window saying:
Progress
 This page displays the progress of the download or installation.
RUnning...
No package
/etc/postinstall/XFree86-bin-icons.sh

When I run that file manually, it completes.

Also, there are a LOT of files in /etc/postinstall.  Can they be 
deleted? Should they be deleted automatically?

On the other hand we don't see
* call foo2()
  and
* call foo3()
here :

$ objdump -CS t.o | grep foo

This is a known bug (as a search of the recent archives would have shown).
People are investigating.  As a short term workaround, you can "mv
/etc/postinstal/XFree86-bin-icons.sh{,.done}" and rerun setup.

They could be, but why?  Besides, they don't take up much space (I think
the total is about 100k, except for the gcc-mingw tarball).  So don't
worry about them...

Yes, apparently the .s file is not the final assembly output -- some
transformations do happen between that and the object file.  So, look at
the output of objdump and see if there are calls to those functions.

One thing to note is that in gcc (as in many other compilers) inlining can
happen at different levels.  What you're probably seeing here, IMO, is a
peephole optimization that inlines any empty functions, rather than gcc
considering the 'inline' keyword.

So, to answer your original question, I don't think the 'inline' keyword
influenced the final binary, but the functions did get inlined by some
other mechanism.

Domain Users

2003-10-08 Thread Boris Mayer-St-Onge

Recently, we have upgraded our version of cygwin from 1.3.12-2 to 
1.5.5-1.  Since that, we have a problem with domain users.

Cygwin is installed locally on each computer by the local administrator 
and it is used by domain users.  If we open a bash shell, we have the 
following messages:

bash: cannot create temp file for here document: Permission denied
Your group is currently "mkpasswd".  This indicates that
the /etc/passwd (ans possibly /etc/group) files should be rebuilt.
See the man pages for mkpasswd and mkgroup then, for example, run
mkpasswd -l [-d] > /etc/passwd
mkgroup -l [-d] > /etc/group
Note that the -d switch is necessary for domain users.
If we add "Domain Users" in the /etc/group file and one domain user in 
the /etc/passwd, this user can then use cygwin correctly (but we still 
have the message concerning the temp file.  Any hints?).

The problem is that we have several hundren of users and some of them 
are added and deleted each week.  Is there an other solution that adding 
all the users in the /etc/passwd file?

Boris

Well, I can.

I've got an XP box running a current CVS compiled cygwin DLL,
a current CVS compiled cygpath, and a just downloaded setup stuck
reinstalling XFree86-bin-icons.  I attached gdb to cygpath and got the
following.

It looks to me like the stack is corrupted, but I'm probably just being
naive.  I included all three thread backtraces just in case anyone can
see anything.  Let me know if have any better idea about how to track this
down.

At a guess, this is because you have TEMP set to some directory that
domain users cannot access.  You could add a "TEMP=/tmp" at the top of
/etc/profile, and see if it helps.  Oh, and make sure /tmp on every
computer is mode 01777, so that it *is* writeable by everyone.

Unfortunately, the SID of the user should be in /etc/passwd for the user
to have full use of Cygwin's services, etc.  One possible solution in your
situation is to keep one centralized user database on a shared drive and
mount it as /etc/passwd on each machine (and similarly for groups).  That
way, when you add and remove users, you will only have to change one file.
The UIDs for the standard accounts (i.e., Administrator{,s}, SYSTEM, etc)
are usually pretty standard, at least on NT-based OSs, but I'm not too
sure about the SIDs, so you might have some problems there...  Also, be
aware that security attributes on shared drives are controlled by the
"smbntsec" setting in the CYGWIN environment variable, rather than
"ntsec".

Have we ever gotten a 'ps -ef' when setup.exe is hung?  It would be nice
to know if it is sh or bash that is having problems or cygpath itself.

I can't find one of these in the archives but I could easily have missed
it.

cygpath hang - using gdb

$ MODE=ironic rant

 "I'll be back" - is this a general salute nowadays? ;-P

You're about to see me trying to use gdb for the first time. Say after me
please: "YES, WE LOVE IT!" ...  Ahh... I didn't hear you ;-)

$ MODE=serious

Looking at "sample use" in "info gdb" I see things that looks fairly
straight forward and familiar. Now when I try "gdb --pid=" -
when cygpath has hung - I end up with a situation that I don't recognise
from that sample.

A couple of "s" commands and the gdb session ends up having no "(gdb)"
prompt. I get the impression that cygpath has stopped somewhere in a system
DLL, and debugging fails in there. Killing cygpath makes the prompt return.

In hope that it will tell SOMETHING I have copied two sessions into the
remainder of this message.

 I'll be persuing this a bit more, but that might take some time.
Please *DO* point out facts for me if you see anything useful.

I don't understand how that will tell you what is hung, but here you go.
I am pretty sure it is cygpath.

IIRC, it was the cygpath process itself.  When cygpath was killed, the
postinstall could continue.  See

This is unfortunately a standard stack for a frame-pointerless function
(probably *WaitForMultipleWindowsEx).  The laborious way to find the
caller is to do something like a:

x/200x $esp

and then look for 0x6100 addresses in the output, decoding them with
something like:

l *0x61041234

There will be some garbage on the stack so some 0x6100 addresses will
not be useful.

That's the only way I know of to deal with this.  If gcc produced dwarf2
output, we could use the CFI to get more accurate information about the
stack frame but that's not going to happen anytime soon.

The trace from thread 2 is what I would expect.  Thread 1 is obviously waiting
for something but I don't know what without more stack info.

Looks like messages posted to the newsgroup gmane.os.cygwin via NNTP
don't get the signature added. I suspect that messages _mailed_ to the

No, you've stepped into the part that is hanging, so gdb is waiting patiently
for it to return.

I did try searching the archives and the official faq first but didn't 
find an answer to my question.

Where are the rsh and telnet clients for cygwin?  In my previous 
installation I believe they existed but since I have moved to this new 
machine, I can't find it anywhere on the setup.exe installation list.

[ANNOUNCEMENT] CMake-1.6.7-1

2003-10-08 Thread William A. Hoffman

CMake 1.8.1-1 is now available on Cygwin mirrors.

This is a major release from 1.6.7 to 1.8.1.

Changes from 1.8.0 to 1.8.1:

Added initial support for MinGW builds on Windows. Fixed a couple bugs in the
ctest program. Some fixes to the FindThreads and FindwxWindows modules. A fix
to the Custom Command dependency code. Better error reporting for ctest and
loaded commands.

Changes from 1.6.7 to 1.8:

The custom commands have been rearchitected to use a more understandable
signature. The old signature should still work. Ctest has been enhanced and
can produce testing dashboards compatible with Dart in many cases. A new FILE
command has been added that supports reading, writing, and globing of
files. A new help target is created for all Makefiles so you can do nmake
help (or make help) Command line options (-D) for cmake no longer require the
type of the argument. The on-line help for cmake has been significantly
improved. Run cmake -help for more information. Support for windows paths and
filenames that include &. Support for files with multiple "." in them for
nmake. More Modules report results to CMakeOutput.log and CMakeError.log. And
of course a number of minor bug fixes and enhancements.


See www.cmake.org for more information.

 This is how it looks for me, when I try to follow the description above...
HTH (not really expecting it to) :-I

This is W2K adv server, SP4+ as I've told before... last and latest of all
cygwin packages - and setup2.416-1  (updated this evening from rcn.net)

Hannu,

Can you attach to a hanging cygpath process with strace and post the
output?

Ok. Got that.
Now; Any ideas how to work further on this?
Set breakpoints at "random" places in cygpath?

I've been persuing a display of source to get a grip on what and where
things are happening, but that seems to be totally over my head at the
moment.

Probable cause: I don't know a single thing about Windows nor Cygwin
internals - and I'm seeing nothing but those parts of memory.

Use the Cygwin package search page at  and
search for "bin/(rsh|telnet)( |.exe)".

In other words, you are not running with a debugging version of
cygwin1.dll so there are no debugging symbols available.

Build a cygwin1.dll with --enable-debugging, install it, build cygpath.exe,
install it.  "set CYGWIN_DEBUG=cygpath" at the command prompt before running
setup.exe.  That will pop up a debugger when cygpath is run before main is
hit.

Ok.  Thanks.

The hand decoded trace (The same one as before.  I still had gdb up.) is
below.

Was that a hint for me :).  Getting gcc to product dwarf2 output is easy.
Getting the resulting executable to run with the dwarf2 sections is the
hard part.  It (dwarf2) needs a section relative relocation in gas/ld/bfd
like I said before.  Know anyone who wants to help? :D

Just out of curiosity, does it hang if no other cygwin programs are running
at the time you run setup?

 Yes.

 The other processes are there for my convinience only, to make

Alrigth. As time eludes me this evening (soon 22:00 local time), I'll have a
shot at that tomorrow. If Brian Ford doesn't get at it before me, he seems
to have that running already.

Logon failure: unknown user name or bad password

2003-10-08 Thread shimsha rao

I am using windows 2000 professional. It has one
global account and 2
local accounts. Recently, I changed my global
account's password.
Since then, I am facing problem in running the
following commands in
cygwin:

$ mkgroup -d
NetGroupEnum() failed with 1326
$ mkpasswd -d
mkpasswd: [1326] Logon failure: unknown user name or
bad password.

It used to work properly before changing the password.
What is causing
this problem? I can access network computes.

thanks,
shimsha

make install does nothing

2003-10-08 Thread Joost Kraaijeveld

I have this makefile with the following target (the maMakefile is from
MICO 2.3.10):

...
install:
for i in $(INSTALLDIRS); do $(MAKE) -C $$i install || exit 1;
done
if test -f doc/doc.ps; then \
$(IDIRCMD) $(SHARED_INSTDIR)/doc/mico; \
$(IMANCMD) doc/doc.ps
$(SHARED_INSTDIR)/doc/mico/manual.ps; \
fi
-ldconfig
...

If I do "make install", make responds with "make: 'install' is up to
date. If I rename the target to "install1" it works as expected. Am I
missing something and is this behaviour by design?

This ia a problem with MakeMaker.  It just looks for .a libraries and
doesn't see the .dll.a import library,  I thought it was fixed, which
version of perl are you using?

As a workaround try creating a symlink libgmp.dll.a libgmp.a or create
an empty libgmp.a in /usr/lib.

Perl Tk in Cygwin (using X)

2003-10-08 Thread Charles Plager

Hello,
	I'm not sure if this is a cygwin problem or a Tk problem.  I am trying 
to build Tk under cygwin.  I did this successfully 5 months ago, but it 
doesn't work anymore.

1) Is there a fix/work around to this problem?
2) Is there a place to just download the Tk X binaries for cygwin? Or, 
can comebody tell me how to use my binaries on another cygwin install?

Thanks,
  Charles
What I did:
unix> perl -MCPAN -e shell
CPAN> get Tk
CPAN> exit
unix> cd .cpan/build/Tk804.025/
unix> perl Makefile.PL x
unix> make
Things start compiling nicely until below.

Note 1: This happens both on my computer and a "brand new" install of 
cygwin.
Note 2: Again, I successsfully build Tk with my computer almost 1/2 a 
year ago.  I haven't uninstalled any libraries.

I had limited success debugging this with an older Cygwin CVS built DLL
(probably around 1.5.3).  It showed an error accessing the pinfo (SEGV).
Sorry, no more detail right now.

My current CVS compiled Cygwin DLL causes this in gdb which makes
debugging this pretty impossible for me:

Hmm, yes -- in my case I'm getting a segfault, so it's apparently broken.
If I have time later this week, I'll build a debugging version of strace
to see what's going on here.

Do you have a directory or a file called "install" or "INSTALL"?  If so,
make thinks that that's the target you need to make, and reports it as
up-to-date.  You can do one of two things: change the Makefile to add a
".PHONY: install" (a good thing to do in any case), or add
"check_case:strict" to your CYGWIN environment variable (won't work if
"install" is an actual file/directory).

I'm pretty sure that the segfault happens when accessing the pinfo, I just
don't have a stack trace handy.  I think it was under
cygwin_internal(CW_CYGWINPID_TO_WINDOWSPID) or the like (I'm going from
memory here).

Aha, yep, an INSTALL file. I will try the check_case:strict.

Re: Domain Users

2003-10-08 Thread Boris Mayer-St-Onge

bash: cannot create temp file for here document: Permission denied
At a guess, this is because you have TEMP set to some directory that
domain users cannot access.  You could add a "TEMP=/tmp" at the top of
/etc/profile, and see if it helps.  Oh, and make sure /tmp on every
computer is mode 01777, so that it *is* writeable by everyone.
The TEMP variable is set, and is %USERPROFILE%\Local Settings\Temp. The 
directory exist and user have write access (but not everyone, I will do 
test with that).

Your group is currently "mkpasswd".  This indicates that
the /etc/passwd (ans possibly /etc/group) files should be rebuilt.
See the man pages for mkpasswd and mkgroup then, for example, run
mkpasswd -l [-d] > /etc/passwd
mkgroup -l [-d] > /etc/group
Note that the -d switch is necessary for domain users.
The problem is that we have several hundren of users and some of them
are added and deleted each week.  Is there an other solution that adding
all the users in the /etc/passwd file?
Unfortunately, the SID of the user should be in /etc/passwd for the user
to have full use of Cygwin's services, etc.  One possible solution in your
situation is to keep one centralized user database on a shared drive and
mount it as /etc/passwd on each machine (and similarly for groups).  That
way, when you add and remove users, you will only have to change one file.
The UIDs for the standard accounts (i.e., Administrator{,s}, SYSTEM, etc)
are usually pretty standard, at least on NT-based OSs, but I'm not too
sure about the SIDs, so you might have some problems there...  Also, be
aware that security attributes on shared drives are controlled by the
"smbntsec" setting in the CYGWIN environment variable, rather than
"ntsec".
Thanks for the answer.  I will check what I can do.  Two more questions:

1- From what I understand, this problem occur only since version 1.5.x 
of cygwin.  Is that right?

2- Is it possible to install a older version of cygwin (we have all the 
file of version 1.3.22-1 except the setup.exe).  When we try to install 
cygwin with the setup.exe from the web page and with the files from a 
local directory, we have errors.  Is it possible to have an older 
version of setup.exe?

Does this mean it thinks it is on Win32, rather than Unix? Why

The message is not produced by cygwin itself by by the /etc/profile
script, which you can easily edit to remove the section of code that
checks the group name. It's just a warning, nothing bad will happen as
long as you don't try to use features (e.g. chown and various services)
that require a complete /etc/passwd. I would recommend doing that rather
than trying to go back in time.

This problem has now been explained with James' help and this message
is to close the thread.
It turns out that on some recent Windows systems a special privilege,
"create global objects", is required to run Cygwin 1.5.X from
a terminal session. It can be given to users with the "editrights.exe"
utility.

problem with tcsh-6.12.00-7.tar.bz2

2003-10-08 Thread Andrew Grimm

This package includes /etc/csh.login which has the line:

set TERM=cygwin

This should instead read:

set term=cygwin

which will set the shell variable term and the environment variable TERM
correctly when tcsh is used as the base shell for the Cygwin shell window.

So, if I can believe this trace, it looks like cygwin is hanging waiting for
a lock while exiting.  I don't see how it's possible to be waiting for
a lock unless cygpath was a multi-threaded app or if the signal thread
grabbed the lock and didn't give it up, neither of which should be the
case.

So, color me puzzled.  I will continue to ponder this, though.  I haven't
had a shower yet.  That's where most of my inspiration hits me...

...Well, it's close to the shower, anyway...

When setup hangs there is a log file
