19 symlinks with missing target

[fergus]

In something like 90,000 files for the current full installation, of which
4,439 are symlinks, there are 19 with missing or wrongly defined target.
They are 

 /bin/X11 -> ../X11R6/bin
 /bin/aclocal-1.4 -> ../autotool/stable/bin/aclocal-1.4
 /bin/aclocal-1.9 -> ../autotool/devel/bin/aclocal-1.9
 /bin/automake-1.4 -> ../autotool/stable/bin/automake-1.4
 /bin/automake-1.9 -> ../autotool/devel/bin/automake-1.9
 /bin/rcs2log -> ../share/cvs/contrib/rcs2log
 /lib/X11 -> ../X11R6/lib/X11
 /lib/gcc-lib/i686-pc-cygwin/3.3.3/adalib/libgnarl.so -> libgnarl-*.so
 /lib/gcc-lib/i686-pc-cygwin/3.3.3/adalib/libgnat.so -> libgnat-*.so
 /lib/gcc-lib/i686-pc-mingw32/3.3.1/gnat1.exe ->
../../i686-pc-cygwin/3.3.1/gnat1.exe
 /lib/rpmpopt -> rpm/rpmpopt
 /lib/terminfo -> ../share/terminfo
 /usr/X11R6/include/X11/X11 -> ../X11R6/include/X11
 /usr/X11R6/share/tcm-2.20/help/CHANGELOG -> ../../CHANGELOG
 /usr/X11R6/share/tcm-2.20/help/COPYING -> ../../COPYING
 /usr/man/de/man1/gsbj.1 -> gslp.1
 /usr/man/de/man1/gsdj.1 -> gslp.1
 /usr/man/de/man1/gsdj500.1 -> gslp.1
 /usr/man/de/man1/gslj.1 -> gslp.1

I can see that all those under /bin/ and some but not all under /lib/
actually work properly when mounted respectively under /usr/bin/ and
/usr/lib/. I got the listing by a simple translation of (sp)->(sp) to /../
for all symlinks and seeing whether the file or folder thus defined existed.
In 4,420 cases (99.6% success) it did. None of these 19 others seems to be
particularly problematic (but then I have never knowingly sought to use
them).

Tried it and it doesn't solve the problem for me. It shifts the trigger
pattern though.

Without the patch, an almost sure thing to do to trigger the bug is to
run the configure script under "strace bash". But with the patch, I have
not been able to trigger the bug once.

However, just running the configure script without straceing bash
triggers the bug at about the same rate as without the patch (I estimate
that between 1/3 and 1/2 of the runs fail).

But wait, now I tried to trigger the bug with the original bash and that
also fails when straceing. So I guess my remark about the shift in
trigger pattern is not certain...

/me makes a note of the phase of the moon

I have not noted any occurance of the "Found old pid..." message. Is
that an indication that the patch never kicks in?

Cheers,
Peter

Okay.  While this wouldn't undo changes made by ssh-host-config to
c:/windows/services, I don't really think that'd be the source of the
error.

Very true.  Yeah, I should at least do that.  And I just now saw your
note about ssh-user-config and realised that I didn't know about it at
all - so I may have some more fruitful avenues to pursue than I thought.

Many thanks,

These are actually symlinks from /usr/bin -> target and then they
should be correct.

These two are wrong because there ain't such thing as a shared gnat
library, but they are installed during gcc installation. I'll see if I
can fix it.

>  /usr/X11R6/include/X11/X11 -> ../X11R6/include/X11

This one is bogus.  It should be /usr/include/X11 -> and points to the
actual X11 header directory.

For us, for many months now, X11 hasn't worked after any fresh Cygwin
install, due to the "missing font "fixed" problem) - see
http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-error-font-eof

In fact, our install process now runs setup, runs various commands as
per the faq entry above, then re-runs setup and requires the user to
re-install the X fonts.  After that X will work.

On top of that, there were changes to -multiwindow and other parameters.
We now default to starting X in a way that boils down to this:

xinit -- -rootless -clipboard -logfile /tmp/XWin.log.$USER

The .$USER is important if multiple people may use the machine - the
default choice of /tmp/XWin.log will make X fail to start because a
later user won't have write permissions on /tmp/XWin.log.

Anyway, try the above, and check out the contents of the log file to
help work out what's going wrong.

I'm coming in to this discussion late, and this is probably way off
topic.  But I once thought bash wasn't reporting status of the previous
command properly (as reported via $?), when what was really happening
was that I was executing other commands as part of my bash prompt, and
bash was reporting the (successful) status of the last of those
commands!

I.e. I'd get a different result by doing:

some-command
if [ $? = 0 ]
then ...

and doing

some-command && ...

I've applied a patch to Cygwin which hopefully solves that for any sort
of remote share.  I tried this with shares on Samba, NT4, XP64 and 2K3.

I know this problem with a slightly different text:

  permanently_set_uid: was able to restore old [e]uid

Note "uid" instead of "gid".  But that problem has been solved already
about a year ago.  I'm a bit surprised to see the above message and I'm
unable to reproduce that problem.

While it's easy to workaround it in OpenSSH, I'd like to understand
why that happens, first.

Could you please send your /etc/passwd and /etc/group files, as well
as the information on which system this is running?

  The advice in the faq to delete

"...The registry tree `Software\Cygnus Solutions' under HKEY_LOCAL_MACHINE
and/or HKEY_CURRENT_USER..."

obviates the need to umount anything manually, doesn't it?

[automake-1.9] aclocal problems

Hello Charles,

I'm having problems with the new automake.  I'm getting no aclocal.m4
file as usual and therefore, there are several unexpanded macros from
configure.in which causes autoconf to fail.  It is nice to see that
there are major aclocal bugs handled with this new release, but it
seems that they also introduced new problems.

Is cygffi.dll needed for SableVM JVM? [was: Re: Is there a Windows version of SableVM?]

As I mentioned before, we had a version of SableVM that worked with
Cygwin.  Most (or all?) of the source changes needed to make it work
should be already included into the current official version.

The most tricky part (for me, at the time I didn't know much about
Cygwin) was getting a shared library of libffi.  SableVM currently
does not allow for static compilation, so we needed to compile
/bin/cygffi.dll ourselves.  Once that was done - the rest was easy.
This was acceptable as an experiment, but in the long run we'd like to
have a Cygwin package of SableVM, so we need a cleaner method. [*]

There's two possible solutions I can see:
1. include shared library of libffi into official cygwin gcc-java
(along with ffi headers)
2. make libsablevm link against statically compiled libffi.

I am not sure 2) is possible and I don't know how to do it.  SableVM
consists of 3 binary parts: /usr/bin/sablevm binary wrapper that loads
libsablevm which in turn loads via ltdl_open JNI libraries from
sablevm-classpath.  In such scenario, would it be possible for
libsablevm to link against static libffi?  How to accomplish that

RE: bash script doesn't wait for commands to complete

[Dolton Tony AB]

I've now realised that this is actually the same problem as described in the
thread "Re: Bash returns incorrect process status" - it's the fact that bash
is reusing process ids that is causing the problem. I've tried the patch in
http://cygwin.com/ml/cygwin/2004-09/msg00783.html and it prevents the
errors.

  Your application probably has a bug.  Cut it down to a dead simple
testcase: just open a single file, read something from it, and close it,
printing return values and errno after each operation.  If that works, it's
not a cygwin bug.  If that doesn't, post the testcase and people can try to
reproduce it.  You might also be able to deduce what's happening by watching
file activity while your application runs and fails with a utility such as
filemon from sysinternals
(http://www.sysinternals.com/ntw2k/source/filemon.shtml)

You can link against static archives when using 'pass_all' instead of
'file_magic ^x86 archive import|^x86 DLL' to recognise dependent
libraries in libtool (change in libtool.m4).

RE: Bash returns incorrect process status

[Dolton Tony AB]

(Sorry if this doesn't appear in the right place - I'm still unable to
subscribe to the list and had to bodge a reply.)

I would just like to say that the patch specified in
http://cygwin.com/ml/cygwin/2004-09/msg00783.html fixes the problem that I
reported in http://cygwin.com/ml/cygwin/2004-09/msg00401.html. Obviously, it
wasn't simply the exiting of the background processes that was the problem,
it was the reuse of pids as well.

Given the caveats attached to the patch, I'm hoping that a "proper" version
will eventually be issued in a new release of bash. Will this be the case?
I've noticed that bash doesn't get issued too often.

Regards,
Tony

Thanks.  I guess the FAQ could say something about using umount -a
but "umount -a" doesn't (yet) remove the Cygwin registry entries
so you couldn't get a clean install without actually going into
the registry.

...and just imagine the feeling of empowerment! You've edited the
registry! You're practically a hacker at that moment.  Well, you're at
least a programming guru...

Do you see the patch kicking in, the "Found old pid..." message on stderr?

There is more to the story, see 
http://cygwin.com/ml/cygwin/2004-09/msg00812.html

Also it's not surprising that the current snapshot doesn't fully fix
the problem http://cygwin.com/ml/cygwin/2004-09/msg00813.html ,
increasing the pid reuse period only reduces the likelihood that
the problem shows up.

ssh missing from cygwin distribution?

[Kevin Kuo]

Hi everyone,
I installed cygwin yesterday and checked the packages X and develop and 
libopenssl.  I was expecting ssh to be installed like previous cygwin 
installs, but this time it wasn't.  I ran setup again and couldn't find 
ssh anywhere!  Has ssh been removed from the cygwin install?  If so, how 
to I get it back?  If not, how do I install it?  Thanks.

file I/O and calling executables from a DLL?

[Lester Ingber]

I'm having problems executing file I/O and calling executables from
a DLL?  I know this sounds simple, and this works fine under Excel,
but I'm having problems doing this with TradeStation.

Is there anything I should know about changes in paths, root directories,
etc., that can occur under different applications?

I have modified a simple code to prepare a DLL from a fairly well-known
tool, dllhelpers,
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/dllhelpers.html
and I have produced an equally good DLL using a Makefile enclosed.
I've just added a call to another independent executable.  This works
just fine (using either the more standard dllhelper way or using my
own Makefile) under Excel using the dllhelpers-prepared dlltest.xls.

Here's some simple code I prepared to explain what I've done.  I'm using
*all* the most current Curr downloads via setup.exe from cygwin.com.

Makefile for cdll.c:
8< top cut -> bottom ->8
DLL_OPTION=-mrtd  # I found this necessary for DLLs to work
CYGWIN_OPTION=-mno-cygwin $(DLL_OPTION)

CC = gcc
CDEBUGFLAGS = -g -O -Wall
CFLAGS = $(CDEBUGFLAGS) $(CYGWIN_OPTION)

LDFLAGS = $(CYGWIN_OPTION)

obj_libs = cdll.o
dllmodule = cdll
dependency_libs = -lm
all:
$(CC) $(CFLAGS) -c -o ${obj_libs} cdll.c
$(CC) $(CFLAGS) -mrtd -shared -o ${dllmodule}.dll \
-Wl,--out-implib=${dllmodule}.lib \
-Wl,--compat-implib \
-Wl,--add-stdcall-alias \
-Wl,--enable-stdcall-fixup \
-Wl,--enable-auto-import \
-Wl,--enable-auto-image-base \
-Wl,--whole-archive ${obj_libs} \
-Wl,--export-all-symbols \
-Wl,--output-def=${dllmodule}.def \
-Wl,--no-whole-archive ${dependency_libs}
8< bottom cut <- top ->8

cdll.c  (In Tradestation, you have to change double->float):
8< top cut -> bottom ->8
#include 
#include 
#include 
#include 
#include 

double dll_double_square (double d);

double
dll_double_square (double d)
{
  char trd_comm[200];
  FILE *ptr_comm;

  /* I tried this with a system() call, but it still doesn't work when
 dll_double_square is called in TradeStation */
  sprintf (trd_comm, "run_trd.exe");
  ptr_comm = popen (trd_comm, "r");
  pclose (ptr_comm);

  return d * d;
}
8< bottom cut <- top ->8

Makefile for trd.c:
8< top cut -> bottom ->8
CYGWIN_OPTION=-mno-cygwin

CC = gcc
CDEBUGFLAGS = -g -O -Wall
CFLAGS = $(CDEBUGFLAGS) $(CYGWIN_OPTION)

LDFLAGS = $(CYGWIN_OPTION)

obj_libs = trd.o
all: $(obj_libs)
@$(CC) $(LDFLAGS) -o run_trd.exe $(obj_libs) -lm
8< bottom cut <- top ->8

trd.c:
8< top cut -> bottom ->8
#include 
#include 
#include 
#include 
#include 

int main ();

int
main ()
{
  char trd_comm[50];
  FILE *ptr_comm;

  sprintf (trd_comm, "mkdir ..\\IO\\%s", "test_dir");
  ptr_comm = popen (trd_comm, "r");
  pclose (ptr_comm);

  printf ("mkdir test_dir\n");

  return 0;
}
8< bottom cut <- top ->8

I have the same non-results in TradeStation, but OK results in Excel,
if I simply create the test_dir within cdll.c, e.g., *not* calling any
other executable.

In TradeStation, the code returns just fine, and goes on to do other
stuff, but the commands I cite just are not being executed?

I also tried including explicit paths, e.g., prefacing the executable
and file with c:\cygwin\..., and not even using any relative paths like
"..", but with no positive effect.

Thanks.

Lester

Is it possible to pass parameters to rxvt?

[Hughes, Bill]

Is it possible to pass a parameter to rxvt to start bash up in a specified
folder?

I suspect I don't know enough to construct the proper string.

I normally start rxvt from a keyboard shortcut to the command
D:\cygwin\bin\run.exe rxvt -name 17 -e /usr/bin/bash --login -i

which works fine.

I also have a registry entry to start cygwin in a specified folder from the
explorer context menu, set up so:
REGEDIT4

[HKEY_CLASSES_ROOT\Directory\shell\BashHere]
@="bash here"
[HKEY_CLASSES_ROOT\Directory\shell\BashHere\command]
@="D:\\cygwin\\bin\\bash.exe --login -c \"cd '%1' ; exec /bin/bash -rcfile
~/.bashrc\""

which also works fine, it's just that I'd rather invoke rxvt.

I have googled for it but not found anything obvious (but it is late Friday
afternoon here), if anyone can drop me a hint, even a better search
selection I'd appreciate it.

BTW while in the subject of registry hacking if there's any emacs fans out
there I find this rather useful too:
[HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\emacs]
[HKEY_CLASSES_ROOT\AllFilesystemObjects\shell\emacs\command]
@="D:\\util\\emacs-21.3\\bin\\gnuclientw.exe \"%1\""

Hmm - the other editor I do this with is the Hessling editor (the), I was
wondering if there are any other users on list?

Hi,
this little upgrade tip seems to be working great (it's not finished
yet) ... however, i have no idea what it is doing.

i would like to simply upgrade all of the packages i currently have
installed. not install anything new, not uninstall anything i already
have.

i couldn't find any info on command line switches to setup.
setup -h,--help, /? did not show anything.
further, i couldn't find any documentation on the cygwin site about
this.

can anyone point me in the right direction, as i find this easier than
fiddling with the setup GUI.

is there any way to "grap" single packages this way ?


what i would really love is a dpkg/apt-get system for cygwin ...
i guess i'll have to wait for that one.
:)

Sorry to reply to myself but I realised what I was doing wrong, this works:
[HKEY_CLASSES_ROOT\Directory\shell\rxvt]
@="rxvt"
[HKEY_CLASSES_ROOT\Directory\shell\rxvt\command]
@="D:\\cygwin\\bin\\run.exe rxvt -name 17 -e /usr/bin/bash --login -c \"cd
'%1' ; exec /bin/bash -rcfile ~/.bashrc\""

sorry for the waste of time, bandwidth etc: PEBKAC.

apache2 as service

[Prakash Khemani]

Hi,

I compiled & installed apache2 on cygwin+WinXP. I am able to use it fine
- but I am not able to install it as a service.

The run as User in the httpd.conf file is SYSTEM.

I installed apache2 asa service using the following command

cygrunsrv -I cygapache -p /usr/local/apache2/bin/httpd.exe -a "-k start"
-t auto

When I try to start it 
cygrunsrv -S cygapache

I get the following error

cygrunsrv: Error starting a service: QueryServiceStatus:  Win32 error
1062:
The service has not been started.

Nothing is written to /var/log/cygaapche.log or to
/usr/local/apache2/log/error_log

The pid stored in httpd.pid changes but the httpd processes don't show
up on doing ps -ae

What am I doing wrong?

I compiled and installed apache2 as the network user ENG/khemani. I had
to change the permissions on apache2/logs directory to be able to run
apache2 as the user SYSTEM.

What more should I do?

Thanks,
Prakash

I'll assume that it seemed to install correctly.  As a quick simple 
sanity check try typing the command in a bash prompt and see what 
happens.  Make sure that starts ok.  If it goes to the background, you 
will need to find the parameter that keeps apache in the foreground.  
cygrunsrv needs this.  Otherwise it can say that the service has not 
started when it is running.

When I try to start it
cygrunsrv -S cygapache
I get the following error

Check the windows event viewer for more logs.  Might be nothing, but 
might also give hints to what may be happening.

Almost sounds like apache wants to start, but is encountering a problem.

Problem with ncurses-5.3-20030719-patch.sh

[Adrian Ford]

Dear All,

I came across a problem when installing ncurses-5.3
source using the setup utility. The problem is in the
ncurses-5.3-20030719-patch.sh script which is called
by the primary install script ncurses-5.3-4.sh. The
patch script begins by unconditionally deleting some
extracted files e.g. lib_insstr.c extracted and then
calls the command "patch" expected in /bin. On my
system at the time of installation I did not have the
patch utility installed - in setup this is a seperate
download, so the script ran something like this:

Patching
patch: not found
patch: not found
patch: not found
.
.
.
...unable to make target lib_insstr.c required by
lib_insstr.o

Basically because the file was deleted and /bin/patch
not available to apply the corrections to the make
files, control is passed back to the parent shell
script then the subsequent make process falls over
with a fatal error. (Interestingly the patch script
seems to exit with status 0 or the install script
would fail?).

Naturally I was able to correct the problem by
installing the patch utility and reinstalling, but in
the supplied INSTALL document, it was not listed as a
prerequisite.

I see two ways of fixing this issue:

1. Modify ncurses-5.3-20030719-patch.sh to check for
existence of patch utility, if not then exit with
non-zero exit status and appropriate error message.
2. Include patch utility with the package (maybe
modify setup utility?)

(I suppose there would be a third option just to
modify the INSTALL document to list patch as a
prerequisite).

Thanks and regards,

Adrian Ford

You should see errors in NT's event log, such as the following:

httpd : PID 7068 : starting service `httpd' failed: signal 12 raised.

> What am I doing wrong?

Did you start cygserver?  Did you set the CYGWIN environment variable to
include "server"?  If not, then do so and try again.

automatic cronjaob injectsion

[Reini Urban]

I know that it might be possible and I know that is not advisable,
but may a cygwin postinstall script or just another helper script
install a cronjob automatically?
echo "$cronline" >> /var/cron/tabs/$USER
kill -HUP `cat /var/run/cron.pid`
crontab -e
Then change a bit in the job file, and save. voila.
A technical issue might be that cron will not react on -HUP. Does it?
I only look at the cron sources at linux some years ago.
I have for example this init.d snippet:
installcron() {
echo "put this into your cronjob:"
echo
echo "*  */3 * * * /usr/bin/freshclam 2>&1 >/dev/null"
echo "#*  */3 * * * /usr/bin/freshclam 2>&1 >/dev/null" >> 
/var/cron/tabs/$USER
kill -HUP `cat /var/run/cron.pid`
crontab -e
}

  Lionel, is your server win 2003?  If so, there's a hotfix for the problem
at the above page.
No, it's W2K, actually.
  The fact that mounting your /tmp on a remote drive is a pretty rare thing
would be another reason.  Remote home dirs, yes, remote /bin dirs yes,
remote /tmp.. not so commonly done.  Owing to a) there's generally no
need nor use for sharing the contents of /tmp with other users and b) it
gets used pretty heavily and mostly for temporary files and data that are
going to be needed again imminently, so for efficiency purposes it would be
nice if the data didn't have to make a round-trip across the network to a
server and then back again when it could just stay on your local machine
where it's needed in the first place.
Agreed - things are actually noticeably zippier with a local /tmp 
(particularly as our network is somewhat crapulous).

As to how/why we ended up with a remote /tmp is as follows: our work 
setup is that most of our (shared) software - including Cygwin - sits on 
a shared drive on machine S, say. We generally terminal serve in to 
machines A, B, C, ... over the network and run stuff from there (which 
may access fs's on machines X, Y, Z...). Now since the default Cygwin 
install sets up /tmp as... well, /tmp, under our setup this means /tmp 
sits on machine S which will be remote as far as machines A, B, C are 
concerned. I wouldn't have thought this to be such an uncommon setup.

Hence the solution to symlink /tmp to /cygdrive/c/temp, as this is 
guaranteed to be local. Perhaps this could get a mention in the 
FAQ/Install notes?

  So why are you asking?  You know the ropes: what does it say at the top of
EVERY single file in /var/cron/tabs?

# DO NOT EDIT THIS FILE - edit the master and reinstall.

  If it's inadvisable, then it seems wildly reckless to attempt a flaky and
improper technique in a postinstall script, because such scripts are going
to be run by every conceivable kind of user in every conceivable combination
of environments and if something can go wrong, it will.  A postinstall
script should be utterly solid (well, as close to as possible) because it's
such a critical part of the cygwin distribution mechanism.  A broken
postinstall script that causes setup.exe to bomb out (rare, but I've seen it
happen) can get users stuck in an endless cycle of download megs of files -
get half-way through installing - setup crashes - restart setup and it
doesn't remember what it's done and needs to re-download everything again.

  So don't do it.  If you want to do this programatically, use "crontab -l"
to dump it to a file, use a sed script to edit it - I don't think blindly
appending a line without making sure you delete the old one would be good -
then "crontab edited-file" to update it.

  That doesn't seem to me any more hard than the three operations you have
in your way of doing it, and it's guaranteed to work.  What motivation for
doing it any other way could there be?

Starting sshd with ipv6 address only

[dimitri berbanov]

Hi,
 I'm running cygwin under Win XP, but I cannot get sshd to listen only on 
ipv6 address. I've installed sshd as a service with "cygrunsrv -I sshd 
--path /usr/sbin/sshd.exe -a -6" (in order to force sshd to use only IPv6 
address), and I've modified sshd_config with "ListenAddress ". But when I try to start sshd "process unexpectedly 
terminates", and  in /var/log/sshd.log it says "bad addr or host:  (no address associated with host name)."

 What could have gone wrong? Any help would be mostly appreciated.

HOME is defined but it IS a logical drive on a network server.
(Does that matter?)

The bash prompt shows "[EMAIL PROTECTED]" and I have no
problems except with some X apps which I think I read is not
unexpected because of some XFree86 issues.

If I move my HOME do I have to change other things (other than
moving what's in it) and can/how do I create the .profile,
.bashrc and .inputrc files in my HOME?

The top of cygcheck output is attached.

FWIW, I have been thinking of implementing a --list option to cygrunsrv
that would list all the Cygwin services installed with cygrunsrv.  At this
point I have no implementation, though.

  Rather than run through the list of services and try and deduce which ones
are cygwin services, the simplest implementation might just be for cygrunsrv
to add a 'created_by_cygrunsrv' value into the service key in
HKLM/CCS/Services, which it can come back and look for later.

It gives good advice, but ends by saying:

This is true.  But for ssh, and other packages, is there any useful

I'm wondering how I get the machine back into a pristine state to

Another feature that would be helpful is an option to show what program

remove all entries from the mount table ("umount -a") and that should
pretty much do it, assuming of course you removed the main

Cygwin doesn't support ipv6 and therefore Cygwin's OpenSSH doesn't suport
it, too.

Yes. It did start ok at the cmd prompt.

I tried httpd -D FOREGROUND -k start

That keeps the httpd process in the foreground at the CLI.

But, even with -D FOREGROUND I get the same error when I tyr to run with cygrunsrv.

Windows event viewer has errors saying that the cygapache service terminated 
unexpectedly.

> Configuration problems.  File permissions.  Check them all.

I doubt that this would be a problem. When I start it at the command line everything 
works fine.

Httpd spawns multiple processes. Can that be an issue?

Thanks,
Prakash

gtk 2?

[Steve Kelem]

Do you know what's needed to get gtk 2.0 to work with cygwin?
I need gtk 2 to get Dia (an open source diagramming package to displace 
Microsoft Visio). (http://www.gnome.org/projects/dia/)

All services created by cygrunsrv have "`cygpath -aw /`\bin\cygrunsrv.exe"
as the executable name.

Umm, yes, I was wondering whether I should have mentioned this one.  I was
thinking of adding this info to the "cygrunsrv -Q" option in verbose mode.
Thanks for bringing it up.

It's actually better to re-mount /tmp as a local dir instead, e.g.

mount -fsb c:/temp /tmp

That way you avoid one network access for each /tmp access (to read the
symlink).

All prerequisites are available as Cygwin packages, should be possible
to build it.  However, there were some issues the last time I tried to
build Dis, e.g. loading modules.  Please continue reporting how it is
going and don't hesitate to ask here or the Dia people for help if you
get errors.

Re: automatic cronjob injection

I know that it might be possible and I know that is not advisable,
  So why are you asking?  You know the ropes: what does it say at the top of
EVERY single file in /var/cron/tabs?
# DO NOT EDIT THIS FILE - edit the master and reinstall.
  If it's inadvisable, then it seems wildly reckless to attempt a flaky and
improper technique in a postinstall script, because such scripts are going
to be run by every conceivable kind of user in every conceivable combination
of environments and if something can go wrong, it will.  A postinstall
script should be utterly solid (well, as close to as possible) because it's
such a critical part of the cygwin distribution mechanism.  A broken
postinstall script that causes setup.exe to bomb out (rare, but I've seen it
happen) can get users stuck in an endless cycle of download megs of files -
get half-way through installing - setup crashes - restart setup and it
doesn't remember what it's done and needs to re-download everything again.
Of course not in a postinstall script, because the user should be able 
to see it and correct it.

But in the following installation steps.
I thought of:
/etc/rc.d/init.d/$package install
/etc/rc.d/init.d/$package installcron
/etc/rc.d/init.d/$package uninstall
("install" / "uninstall" just un-/installs the service, not the package)
So don't do it.  If you want to do this programatically, use "crontab -l"
to dump it to a file, use a sed script to edit it - I don't think blindly
appending a line without making sure you delete the old one would be good -
then "crontab edited-file" to update it.
Good idea. I'll do a grep before blindly adding a new line.
I just add a commented line to crontab, and called:
crontab -e so the user will get an idea what to do.
That doesn't seem to me any more hard than the three operations you have
in your way of doing it, and it's guaranteed to work.  What motivation for
doing it any other way could there be?
The motivation is: users prefer installers, which just do what they 
want, instead of reading docs about required installations steps.

And I wanted a place where all the logic which didn't fit into the 
postinstall script could be executed.
Give permissions to SYSTEM, run cygrunsrv --install with the correct 
settings, blabla.
it's about ten lines.

When you start it at the command line, it runs as you.  When you start it
as a service, it runs as a different user (SYSTEM).  Listen to what people
tell you -- check the file permissions.

It resolved as I exited the subshell and used a new opened shell.  The
problem was that I did an `export LD=gcc` for a prvious build and
libtool thought that my linker cannot build shared executables

Ah, right.  Sometimes you'd see something like "execv: operation not
permitted".  However, the "terminated unexpectedly" message seems to
indicate that apache doesn't start in the foreground...

Actually there is more information in the Event Viewer under
Application.

The cygapache service gave out the following error message

"cygapache : PID 604 : starting service `cygapache' failed: signal 12
raised."

I am tring to run "httpd -k start -D FOREGROUND" as the cygapache
service.

Setting all permissions to 777 on /usr/, /usr/local/ and everything
under /usr/local/apache2 has not helped.

Heh, there you go.  You've seen

Try adding '-e CYGWIN="$CYGWIN"' to your cygrunsrv command line.

Bingo! That worked. In the Windows Environment variables (MyComputer ->
System Properties -> Advanced -> Environment Variables -> System
Variables)  I had CYGWIN set properly all this while - but I guess that
value is not picked up while running services.

Thank you all very much ! :) !

python 2.3.4-1 on cygwin 1.5.11-1 exits when Thread exits

[Dan H]

Whenever any of my python threads exits, python exits, too (regardless of 
the main thread, for example). See below for details. How can I fix this?

Transcript of a python session on cygwin 1.5.11-1:
% python2.3
Python 2.3.4 (#1, Jun 13 2004, 11:21:03)
[GCC 3.3.1 (cygming special)] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
from threading import Thread
t = Thread()
t.start()
%
i.e. when thread t exited, so did python.
Doing the same thing on Linux, python does not exit:
% uname -srm
Linux 2.6.6-1-386 i686
% python2.3
Python 2.3.4 (#2, Jul  5 2004, 09:15:05)
[GCC 3.3.4 (Debian 1:3.3.4-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
from threading import Thread
t = Thread()
t.start()
print "foo"
foo

I have to say that running setup.exe unattended like that in an
automated way is just insane, in my opinion.  It may work but it's not
really supported, we're not at the state where you can really expect to
pull down periodic updates that way and not expect surprises every so
often.

If you run setup.exe and select nothing but 'Next' on each page, then
that's just what you should get.  Why do you have belief otherwise?

That's because they're unsupported.  They're only documented in the
mailing list archives and the source code.

> is there any way to "grap" single packages this way ?

(...assuming here you meant "grab" ...)

Run setup, find the individual package you want, click anywhere in the
"New" column to cycle from "Skip" to the current version.  If the
default "Category" view is scary then switch to "Full" or "Not
installed" if you prefer and you'll see them as a flat list instead of a
tree. Why don't you ask your setup.exe questions directly rather than
skirting the issue by trying to use other nonsupported methods for
getting packages?  Using setup in this manner is the only current sane
way to select packages.

There was another problem. bash keeps track of the
"last_made_pid" and compares it to its previous value
to decide if it should wait on a process.

So if a new command has the same pid as the previous one,
bash won't wait on it.

You might think that this is OK as long as consecutive
forks return different pids. Wrong, because forks used
for some purposes, such as back tick evaluations,
don't count.

So bash is currently unreliable on any system where
processes don't have unique pids. If pid values are reused,
and all intervening forks serve only for backtick evaluations,
bash will return 0 status for a command.
Naturally this gets to be unlikely as the reuse period grows.

Here is another patch against the Cygwin release of bash.
It includes the previous one in this thread. Please try it.

Thanks to Bogdan Vacaliuc and Peter Ekberg for their help.
