On success, it should return 0, otherwise -1. However, it looks like the

I'm surprised that there's nothing in the user guide or the FAQ about

cron as myself.  I decided to make it run as the local system account this

appeared to complete without errors or warnings.  I did this in a "run as

You should see a vi session.
Do you have vi installed?
What is the value of EDITOR?

Yes, I have vi installed.  EDITOR was blank, but I tried setting it to "vi"
and repeating the test, with no change.


This could indicate a deeper problem, confusing not just cron.

Are you familiar with the crontab format? If not, try this:
$ man 5 crontab

Yes, I am familiar with it, but here's the crontab I'm trying to set, in any
case:

0 * * * *   monitorDataSource

Running it as a privileged user is more complicated.

Is there a specific reason why you want to run it as system?

No, only because running it as myself didn't work.

In any case, I tried stopping and removing the service and rerunning cron-
config, running the service as myself.  It didn't make any difference.  No
response from "crontab -e", and "crontab crontab" seemingly ignored.  Nothing
in "/var/log/cron.log", and nothing in "cronevents" except for the service
stopping and starting.

Any more ideas about this?



I guess it is to do with privileges.
cron works on my machines without fail: as system, and as privileged user

If you look at the service
$ cygrunsrv.exe  -Q cron --verbose

You can see that you can run cron from your own account like this:
$  /usr/sbin/cron -n

Anyway, the cron process needs read/write access to
/var/cron/tabs/

No cron file there, means no cron jobs for you.

The fact that you do not get an editor with 'crontab -e' is strange.
I can only guess that EDITOR has a strange value, or crontab dies on privileges.

Have you tried strace?
$ strace -f crontab -e 2>&1 | tee strace.log

You can probably see it dying.

Re: Confused about several issues with setting up cron

2013-09-24 Thread Steve
I would try the following methods:

First make sure you are launching your local terminal with "Runas
Administrator" checked, even if you are the Administrator user. I am
also asuming you have done the normal stuff like cygcheck -c, and make
sure you have not loaded duplicate dlls during your troubleshooting.
If you ever get resource fork issues with parent != child error
messages right in the term, that needs to be fixed by removing the
duplicate dll file. And run /bin/rebaseall from dash or ash terminals
(disable Anti-viri).
Always manually right click and Run mintty as Administrator, also try
changing the path in the mintty shortcut to
c:\cygwin\bin\mintty.exe -
% cygrunsrv -R cron
reboot to be on the safe side
After bootup use cygwin setup to uninstall cron, then run setup again
and install it.
% cron-config
You shouldn't need todo anything custom here, yes and defaults to
everything. It should be using your current user account, and that is
hopefully the full fledged Administrator account, and not some other
user with admin privs. Which also means you are currently logged into
windows as the full Administrator account.
% net start cron
% EDITOR=vi
or whatev
% crontab -e
create an entry that just fires of something basic very frequently for instance
*/1  * * * * echo "this" > /cygdrive/c/Users/
Administrator/Desktop/test.file.txt
You many also want to throw in the PATH into the crontab itself for example:
PATH=/bin:/usr/bin:/usr/local/bin
As alternative to or in addition to the mentioned test.file.txt
creation cron entry, you could use something like this:
@reboot echo "this" > /cygdrive/c/Users/Administrator/Desktop/test.file.txt
So that instead of something fireing off every minute for testing, it
would fire it off each time you stop/start the cron service with "net
stop cron" and "net start cron"

Sorry for the messy response, i have no time right now. Good luck
reading this email and getting it working.  :)

This patch causes failures on at least test-fcntl and test-dup2 on
cygwin (both 32-bit and 64-bit); there, getdtablesize() currently
returns the current runtime value, but this value starts at 256, and
automatically expands as needed at runtime up to 3200.  I think cygwin
should be patched to make getdtablesize() return a constant 3200 (rather
than the current runtime value); but meanwhile, we need to do something
in gnulib to pick a larger value for bad_fd if getdtablesize() returns a
small runtime value.  I also wonder whether cygwin's
sysconf(_SC_OPEN_MAX) should likewise be modified.

(gdb) p getdtablesize()
$5 = 256
(gdb) p dup2(0, 256)
$6 = 256
(gdb) p getdtablesize()
$7 = 288
(gdb) p dup2(0, 3200)
$8 = -1
(gdb) p getdtablesize()
$9 = 288
(gdb) p dup2(0, 3199)
$10 = 3199
(gdb) p getdtablesize()
$11 = 3200

How does Cygwin handle non-Latin1 man pages? (move to UTF-8?)

2013-09-24 Thread Erwin Waterlander

Hi,

As far as I see it, on Cygwin it is assumed that man pages are encoded 
in Latin-1 (ISO-8859-1).

For instance the man pages of vim.

/usr/share/man/fr/vim.1.gz is encoded in Latin-1.

$ export LANG=fr_FR.UTF-8
$ man vim

This will show the French man page correctly. Latin-1 is converted to UTF-8.

For the Russian translation of the vim manual I see two files:
/usr/share/man/ru.UTF-8/man1/vim.1.gz
/usr/share/man/ru.KOI8-R/man1/vim.1.gz


When I type
$ export LANG=ru_RU.UTF-8
$ man vim

I get the English man page, instead of the Russian man page.
I think because there is no /usr/share/man/ru/man1/vim.1.gz present.

When I type

$ export LANG=ru_RU.UTF-8
$ export LANGUAGE=ru.UTF-8
$ man vim

The Russian man page is displayed, but all Russian characters are 
wrongly displayed.

I think because it is assumed the man page is in Latin-1.

To get a correct display of the Russian man page I need to change 
/etc/man.config

I change the line with NROFF to:
NROFF /usr/bin/preconv | /usr/bin/nroff -c -mandoc 2>/dev/null

Now the Russian man page displays correctly, but now all the Latin-1 
pages display wrongly.


So I undo my change in /etc/man.conf


On Linux the trend is to convert all man pages to UTF-8 encoding.
Will Cygwin follow this trend?

regards,

[ANNOUNCEMENT] Updated: m4-1.4.17-1

2013-09-24 Thread Eric Blake (cygwin)
A new release of m4, 1.4.17-1, will soon be available on your favorite
mirror.  This is a new upstream release, and my first build of m4 for
64-bit cygwin; it replaces 1.4.16-1 on 32-bit cygwin, and 1.4.16-2 on
64-bit cygwin.

NEWS:
=
This is a new upstream release, with the following upstream NEWS:

** Fix compilation with newer glibc headers.

** Fix a failure with diverting large amounts of text on mingw (does
   not affect platforms that can rename an open file).

** A number of portability improvements inherited from gnulib.

Note that libsigsegv has still not been ported to 64-bit cygwin; as
such, the 64-bit build of m4 cannot gracefully detect stack overflow
even though the 32-bit build can.  Also note that 'make check' fails on
this build on current cygwin1.dll, due to a testsuite question about
cygwin's getdtablesize() semantics; although the failure is harmless to
m4's actual operation.

You must rebuild from source if you want the experimental changeword
feature enabled, as using it can slow down normal operation, and since
it will disappear from the eventual m4 2.0.

If you encounter a problem that might be cygwin-specific, please report
it here rather than upstream.  See also the upstream documentation in
/usr/share/doc/m4/.

DESCRIPTION:

m4 is an implementation of the traditional Unix macro processor. It is
mostly SVR4 compatible although it has some extensions (for example,
handling more than 9 positional parameters to macros). GNU m4 also has
built-in functions for including files, running shell commands, doing
arithmetic, etc.

UPDATE:
===
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.  Save it and run setup, answer the questions, and look for
'm4' in the 'Interpreters' category.

DOWNLOAD:
=
Note that downloads from cygwin.com aren't allowed due to bandwidth
limitations.  This means that you will need to find a mirror which has
this update, please choose the one nearest to you:
http://cygwin.com/mirrors.html

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

Why?  What does "3200" have to do with anything?  There is not supposed
to be a hard-coded upper limit.

Re: Run bash script in cmd with cygwin

2013-09-24 Thread Ulrich Pogson
Thanks Matt, after try everything I could not get it to work. Could
you give me the whole code that I could enter in cmd that would run
cygwin and then run the script?

Go back and read the gdb session. STC in C:

#include 
#include 
#include 
int main(void)
{
  int ret = dup2(0, 3200);
  if (ret == -1)
printf("3200 errno %d: %s\n", errno, strerror(errno));
  else
printf("3200 ok");

  ret = dup2(0, 3199);
  if (ret == -1)
printf("3199 errno %d: %s\n", errno, strerror(errno));
  else
printf("3199 ok");
  return 0;
}

output on my system:

3200 errno 9: Bad file descriptor
3199 ok
