It will be nice to support Varnish in Cygwin plataform
(http://www.cygwin.com)

After weeks making some tests I was able to build successful Varnish in
Cygwin, the problems that I have found are:

1) Cygwin doesn't support CLOCK_MONOTONIC but HAVE_CLOCK_GETTIME is
defined

2) RTLD_LOCAL is not defined in dlfcn.h headers

3) madvise function and MADV_RANDOM define does not exists, in Cygwin
their correct names are posix_madvise and POSIX_MADV_RANDOM

4) In Cygwin SO_RCVTIMEO_WORKS and SO_SNDTIMEO_WORKS doesn't work
properly because in Windows setsockopt/getsockopt expects time-out in
"int" milliseconds instead of "struct timeval" (in future, i think it
could be fixed)

5) Linkage problems ("Undefined reference" errors). The undefined
reference is because fundamentally ELF (UNIX) and PE/COFF (Windows) are
very different in terms of how linking works under the hood. The short
explanation is that PE/COFF requires all references to be resolved at
link-time:
* http://www.cygwin.com/ml/cygwin/2006-12/msg00592.html
* http://www.cygwin.com/ml/cygwin/2005-07/msg00675.html
* http://www.mail-archive.com/cygwin@cygwin.com/msg81837.html

6) VCL compilation problems ("Undefined reference" errors). VCL compiled
DLL uses simbols from EXE. It is necesary to create a fake import file
from EXE to allow compilation.


I have solved all problems modifing source code and automake scripts. I
attach all modification to this ticket.

It is also necessary to execute varnishd with cc_command parameter in
order to compile VCL correctly:

-p cc_command='cc -shared /tmp/varnish-2.1.2/bin/varnishd/varnishd-
cache_vrt.o /tmp/varnish-2.1.2/bin/varnishd/varnishd-cache_backend_cfg.o
-L/usr/local/lib -L/tmp/varnish-2.1.2/bin/varnishd/ -lvarnish -lvarnishd
-Wl,--export-all-symbols -Wl,-x -o %o %s'


I have tested varnish and works OK.

I think it will be interesting to add this information to wiki:
* http://www.varnish-cache.org/wiki/Installation

I have attached cygwin changes in patch format for r5110.

I also have executed regression tests with r5110. I continue having
problems with:

{{{

Hello,

I have updated my version of varnish for cygwin. It is based on subversion
trunk (r5646)

The new improvements are:
* Better compilation of VCL archives (in the past they were compiled
using objects from varnish compilation directory)
* Fixed regresion tests: varnishtest program server_thread function in
vtc_server.c, after "fd = accept(s->sock, addr, &l);" If socket returned
is wrong, it is not used.
* Fixed regresion tests: varnishtest program is blocked in some tests.
Test is executed succesfully but varnishtest program is blocked when it
stops server thread, so varnishtest timeouts and FAILS.
- Server thread is blocked in TCP accept, waiting a request
(server_thread function in vtc_server.c file) and main varnishtest is
blocked in pthread_join (server_wait function in vtc_server.c file)
waiting server thread to end.
- In linux, pthread_join unblocks thread from its TCP accept but in
Cygwin it does not.
- The solution is to send a signal using pthread_kill (only in cygwin).
The signal unblocks thread from its TCP accept.
- I have tested varnish cache in cygwin against one apache server and it
works fine. The patch applied in a Solaris and Linux server works
properly.

After this changes, the result of regression test are: 9 tests failed, 202
tests passed


Failed tests:

'''c00005.vtc "Test simple ACL"'''
error IPv6 [DNS lookup(::): hostname nor servname provided, or not
known\n]
CYGWIN does not support IPv6 in Windows XP. Maybe it works in newer
versions

'''s00002.vtc "Check grace with sick backends"'''
"Write failed: Bad file descriptor"
UNKNOWN ERROR

'''b00015.vtc "Check synthetic error page caching" and v00009.vtc "Test
round robin director"'''
bind(): Address already in use [.Assert error in server_start(),
vtc_server.c line 183: Condition(s->sock >= 0) not true.]
UNKNOWN ERROR: test server is started two times, the second time it says
that port it is in use

'''VMOD regresion tests: m00000.vtc, m00001.vtc, m00002.vtc, m00003.vtc
and m00004.vtc'''
CYGWIN does not find new VMOD shared libraries
A fix is need in order to load shared libraries of VMOD

Comment (by keretamalam):

I am about to leave and cannot look into this further right now, but I do
want to mention that relying on pkg-config itself is not a problem (as you
said, we also use it later), the problem is that on some systems, the .pc
file for pkg-config is supplying wrong information (whereas on yours, it's
botan-config that is wrong), so that's why I'm trying to make it work with
both (while one of them is bad).
