Hey guys,
does somebody get dovecot work under cygwin?
The compilation finish without any problems. But after trying to run dovecot i got this in my log:
dovecot: Nov 17 02:40:18 Info: Dovecot v1.0.7 starting up dovecot: Nov 17 02:40:19 Fatal: setrlimit(RLIMIT_DATA, 256): Invalid argument dovecot: Nov 17 02:40:19 Error: Auth process died too early - shutting down dovecot: Nov 17 02:40:19 Error: child 1452 (auth) returned error 89
setting auth_process_size to another value didn't fixed this issue.
Thanks for any help Greets

Well, now i do not have setrlimit errors anymore but the log says now:
dovecot: Nov 17 18:50:57 Info: Dovecot v1.0.7 starting up dovecot: Nov 17 18:50:58 Error: Auth process died too early - shutting down dovecot: Nov 17 18:50:58 Error: child 956 (auth) returned error 53
i can not find a list of error codes, what does error 53 mean?
Cheers Ronny

It doesn't come from Dovecot. Probably some of the libraries dovecot-auth is linked against is failing and returns that error. Does Cygwin have "ldd"? What does "ldd dovecot-auth" say?

Well, there is a cygcheck.exe, the output for dovecot-auth is $ cygcheck.exe dovecot-auth Found: C:\cygwin\usr\libexec\dovecot\dovecot-auth.exe C:/cygwin/usr/libexec/dovecot/dovecot-auth.exe C:\cygwin\bin\cygcrypt-0.dll C:\cygwin\bin\cygwin1.dll C:\WINDOWS\system32\ADVAPI32.DLL C:\WINDOWS\system32\ntdll.dll C:\WINDOWS\system32\KERNEL32.dll C:\WINDOWS\system32\RPCRT4.dll C:\WINDOWS\system32\Secur32.dll
all, of the listed dll's exist in their directory.
Well, what confuses me more ist that after fisrt launch the log is

This error is ignored.

The "without error code" most likely just means that Dovecot shut down before it saw that dovecot-auth exited with error 53.
Some things you could try:
Does Cygwin have strace? Run "strace -f dovecot" to see if it shows something interesting.
Is the problem with starting dovecot-auth or after dovecot-auth has already started? Try setting auth_executable = /tmp/test.sh where test.sh is something like:
#!/bin/sh echo "i'm running" > /tmp/dovecot.output exit 0
If that worked, try adding exit(0); as the first statement in src/auth/main.c's main() function to see if it returns 53 before or after it reaches that far.

I put some information output to the code (i do not have a debbuger running yet ;-) )
static void auth_process_input(void *context) { ...
switch (i_stream_read(process->input)) {... case -1: /* disconnected */ i_info("DIE 2"); auth_process_destroy(process); return; case -2: /* buffer full */ ... i_info("DIE 3"); auth_process_destroy(process); return; }
The log is,
dovecot: Nov 21 02:52:09 Info: DIE 2 <<< dovecot: Nov 21 02:52:09 Error: Auth process died too early - shutting down dovecot: Nov 21 02:52:09 Error: child 1300 (auth) returned error 53

This only means that it sees that auth process died, so master process shuts down. Put something similar to src/auth/main.c instead to see if it gets executed.

I put i_info as the first statement in auth/main.c! This do not appear at the log, so the auth process is not executed!?!?
As far as i see this is for executing the auth process:
void client_process_exec(const char *cmd, const char *title) { i_info("LPE6"); execv(executable, (char **)argv); i_info("LPE7"); }
Log output is only "LPE6", so it comes to the point where it should be executed, but does not do it!
BUT!!!: i set auth_executable = /home/Administrator/d.sh
d.sh is
#!/bin/sh echo "running" > /home/Administrator/output exit 0
even client_process_exec() do not comes to "LPE7" the file output is created! So it seems execv() runs the process but then stops and do not return!

By the way, to you use gdb/ddd? Does it work for you? Do you use any special debug level?

That's why I thought that the problem could be that running dovecot-
auth.exe calls some library's init function which causes it to exit.
You could try running directly:
./dovecot-auth.exe echo $?
Does it fail with the same error 53?

Sure I use gdb in Linux, but if you mean in Cygwin I haven't used
Cygwin for years. What do you mean by debug level?
