Isn't that kinda up to the user. When you finish downloading new
packages you kill your internet connection as cygwin setup won't
need it.
Autodialling isn't something that (most) programs do. Windows does it
for
them. So setup doesn't know if a connection was made on it's account or
not.
I'd agree that it isn't something most programs do. I'd disagree if you
were to say Autodialling isn't something that most programs need to do,
however. Windows cannot know that setup.exe has 'finished' with the
internet connection (I believe Windows will by default wait until
setup.exe has exitted before closing the dialup connection) unless
setup.exe gives Windows a hint. I'm almost utterly convinced that a
sequence in setup.exe a bit like the following will do the trick
admirably.
DWORD dwNetAccess;
InternetGetConnectedState(dwNetAccess,0);
if (dwNetAccess INTERNET_CONNECTION_MODEM)
{
// autodial now. windows will update a reference count
// if the connection is already open
InternetAutoDial(INTERNET_AUTODIAL_FORCE_ONLINE, hwndSetupDialog);
}
[snip - setup.exe goes and downloads the packages]
if (dwNetAccess INTERNET_CONNECTION_MODEM)
{
// hang up. windows will decrease a reference count.
// Can't remember if Windows prompts the user if they
// wish to close the dialup connection when the reference
// count reaches zero, or if Windows just does it anyway!
InternetAutodialHangup(0);
}
I'm speculating, I'll try it when I get a chance. Of course this relies
on behaviour built into Internet Explorer 4 and newer (more accurately
built into the version of WinInet.dll shipping with IE 4, or a newer
version of that dll) but setup.exe can easily test for the presence of
this and do what it currently does if it can't find the functions or
can't
find wininet.dll in the path.
Isn't the change from downloading to installing info enough?
Some people won't notice that. A larger issue is if you go away and make
some tea. I for one don't stare at setup.exe while it downloads
eighty-six megabytes of information on a 33.6K modem. (I do sit and
watch
defrag for hours on end though, but that's just me)
http://sources.redhat.com/cygwin-apps/setup.html
Thanks. Will play.
d
I'll leap in here too...
If Windoze is smart enough to autodial when some program wants to use the
internet it then should be smart enough to notice that the connection has
gone idle and do an idle time-out for hanging up. If not, then its broken.
You can't blame the program that USES that auto-dialed connection for not
hanging up. It didn't dial, why should it hang up? Every program that might
use the internet (auto-dialled) now has to be modified to know how to hang
up the connection? What if you have two programs using the connection at
the same time, and one of them decides to hang it up? Oops. Clearly not the
right solution.

I have no personal knowledge of the completeness of cygwin's fcntl() so YMMV. Good luck!

Re: suitable cygwin subset question
So this all is a prelude to the question: What's the minimum subset of stuff I need to move, and is it necessary to actually run a cygwin installer (for registry setups, maybe???) or will simply putting files in the right place work? Without registry entries, Cygwin won't know where / is - so the only paths that will work are /cygdrive paths. Installing a small set of packages with setup is probably the best option, but if you really don't want to do that, 'mount' should enable you to set the necessary info in the registry. Quite how this could cause Oracle code to hang, though, I have no idea. Max. OK, I did a minimal install on a machine without Cygwin, my program then runs. I then used regedit to delete the two sets of cygnus solutions registry keys, and my program now no longer runs (properly). so, maybe all I need to do is set the right registry keys. Could someone in the know explain to me how to use mount to do that? Thanks!

suitable cygwin subset question
I'm developing a multithread app on cygwin (well, porting from LInux, actually), which uses Oracle OCI for client services. So far it's running well on my development box. Just tried an experiment, in which I took my program and its necessary data files, and the cygwin DLLs reported by cygcheck (cygwin1.dll, cygz.dll) to another windows machine, one that has NO cygwin stuff on it at all. Dropped all those files in a directory (for simplicity, I know it's not the long-term right way to do it). My app starts up just fine, it receives its input (via tcp), drops it in its queue and sits there forever. It's got another thread that pulls things out of the queue, processes them and sends off to the Oracle database. But somehow it never seems to actually get anything sent. When I tell the app to terminate, its behavior makes it plain that it's down inside the bowels of the OCI code (as compared to being in my higher-level code that polls the queue), so my guess is it's blocking somewhere in Oracle for some unknown-to-me reason. So this all is a prelude to the question: What's the minimum subset of stuff I need to move, and is it necessary to actually run a cygwin installer (for registry setups, maybe???) or will simply putting files in the right place work? Bash, strace, and ps all seem to work on this configuration, if it means anything. My apologies about the somewhat vague question, I don't know how to be more specific without posting a billion lines of crap. Anybody needs some specific info I'll be glad to provide it.

trouble using a PTY
I'm trying to run some very simple code that uses ptys. The
code is from W. Richard Stevens APUE book. The only change is
the printf you see below. In this routine:
int
ptym_open(char *pts_name)
{
int fdm;
char*ptr1, *ptr2;
strcpy(pts_name, /dev/ptyXY);
/* array index: 0123456789 (for references in following code) */
for (ptr1 = pqrstuvwxyzPQRST; *ptr1 != 0; ptr1++) {
pts_name[8] = *ptr1;
for (ptr2 = 0123456789abcdef; *ptr2 != 0; ptr2++) {
pts_name[9] = *ptr2;
/* try to open master */
if ( (fdm = open(pts_name, O_RDWR)) 0) {
printf (ptym_open, open returned errno of: %d, pts_name=%s\n,
errno,pts_name);
if (errno == ENOENT)/* different from
EIO */
return(-1); /*out of pty devices
*/
else
continue;/*try next pty device
*/
}
pts_name[5] = 't'; /* change pty to tty */
return(fdm);/* got it, return fd of
master */
}
}
printf (pty, at end, errno is: %d\n, errno);
return(-1); /* out of pty devices */
}
the first call to open() fails, and the printf produces:
ptym_open, open returned errno of: 2, pts_name=/dev/ptyp0
As far as I can deduce by reading cygwin docs and mailing list archives,
PTYs would be expected to work.
I'd appreciate it if someone could point me in the right direction here.

This code is non-portable. The names of ptys are system-specific, and
not guaranteed to be named /dev/ptyXY.
On cygwin, master side of pseudo tty can be opened via
open(/dev/ptym,...). Then you can use grantpt(), unlockpt() and
ptsname() functions to access a slave side of pty.
Unfortunately, its not very portable, either. Proposed portable
interface to open master side of pseudo tty is posix_openpt(), but it
haven't been implemented on cygwin yet. Patches are gratefully
accepted (tm).
BTW, implementing this function looks like an easy prey for those who
wish to contribute something to cygwin, but afraid of complexities of

re: pthreads
Following up on my two messages of yesterday, I've narrowed down a bit the
problem I am having with pthread_cancel(), to the point where the thread
I'm trying to cancel doesn't do ANYTHING but loop. No calls to any other
functions at all, just an endless loop..
When I call pthread_cancel() I get back a return code of 3, and the thread
is not cancelled. (If the thread loops, printing out some distinct text
once per loop, the text keeps right on printing beyond the cancel call, up
until the app actually exits).
The value of the thread ID (pthread_t) is the same all the way through the
program from the moment the thread is created up to and in fact after the
pthread_cancel call fails.
I'm stumped.
Here's some little bits of code
The thread creation:
sys_parms.gc_parms.gc_tid = (pthread_t) 0;
rc = start_gc((void *) sys_parms);
printf (sys_parms.gc_parms.gc_tid=%x\n, sys_parms.gc_parms.gc_tid);
and in start_gc:
pthread_t gc_id;
...
if (pthread_create (gc_id , sys_parms-gc_parms.gc_thr_attr, thr_gc,
sys_parms) != 0)
{ /* pthread_create failure */
rc = CANNOT_CREATE_GC_THREAD;
}
printf (gc_id=%x\n, gc_id);
sys_parms-gc_parms.gc_tid = gc_id;
printf (sys_parms-gc_parms.gc_tid=%x\n,
sys_parms-gc_parms.gc_tid);
then later when we cancel it:
printf (sys_parms.gc_parms.gc_tid=%x, rc=%d\n,
sys_parms.gc_parms.gc_tid, rc);
if (sys_parms.gc_parms.gc_tid != (pthread_t) 0)
{
if ((rc = pthread_cancel (sys_parms.gc_parms.gc_tid)) != 0)
{
uif_print (uif_fd, %s%s %s%d%s %s%x%s %d%s,
ERROR: in function , __FUNCTION__,
Cannot cancel Garbage Collection thread,
rc = ,
rc, .\n, gc_tid = ,
sys_parms.gc_parms.gc_tid,
errno = , errno, \n);
return EXIT_FAILURE;
}
Am I out in left field here in some way that I'm too blind to see?
