Mac OS X Tiger 10.4 possible issue related to chunk size

From: Will Senn <will_senn_at_comcast.net>
Date: 2005-11-25 18:44:57 CET

Hi all,

I originally posted this to user@, but was directed to post to this
list as a more appropriate venue. Could y'all take a look and tell me
what might be the matter?

Regards,

Will

Hi,

Please be kind, I've tried a bunch of stuff (including the
ac_cv_func_poll=no workaround from the FAQ) to correct this problem,
all to no avail.

Problem:
Unable to check out repository using HTTP - works fine using file:///

SVN Error:
svn: REPORT request failed on '/svn/!svn/vcc/default'
svn: REPORT of '/svn/!svn/vcc/default': Could not read chunk size:
connection was closed by server. (http://localhost:8080)

Platform:
Mac OS X 10.4.3 (Tiger)
15" Powerbook 1.5Ghz with 1 GB RAM
XCode 2.2
powerpc-apple-darwin8-gcc-4.0.1
Apache 2.0.55
Subversion 1.2.3
Apr 0.9.7
Apr-util 0.9.7

Apr and Apr-util 0.9.7 built from source
from the release notes:
   *) Fix issue with poll() followed by net I/O yielding EAGAIN on
        Mac OS 10.4 (Darwin 8). [Wilfredo Sanchez]

Apache 2.0.55 built from source
./configure --enable-mods-shared=most --enable-ssl --with-mpm=worker
--without-berkeley-db --with-apr=/usr/local/apr --with-apr-util=/usr/

I checked the httpd binary linkages:
$ otool -L /usr/local/apache2/bin/httpd
/usr/local/apache2/bin/httpd:
         /usr/local/apr/lib/libaprutil-0.0.dylib (compatibility

bindings=no --without-berkeley-db --with-apr=/usr/local/apr --with-
apr-util=/usr/local/apr

NOTE: I have built apr, apr-util, httpd and svn with ac_cv_func_poll
set to no and unset as well.

I configured the dav stuff in httpd.conf
added
<Location /svn>
     DAV svn
     SVNPath /path/to/repos
</Location>

make install added these lines to httpd.conf
LoadModule dav_svn_module modules/mod_dav_svn.so
LoadModule authz_svn_module modules/mod_authz_svn.so

I tested svn in the browser
http://localhost:8080/svn and everything looked ok.

I tested svn from the bash prompt
$ svn co http://localhost:8080/svn/trunk .

A file
A another file
A etc...

Finally, I rebuilt apache and subversion with --enable-maintainer-
mode in the hopes of capturing a trace, but the error doesn't occur
with these builds...

I ran
$ sudo gdb httpd
gdb>run -X

but the error didn't occur when I checked out the repository, so I
just ran
$ sudo /usr/local/apache2/bin/apachectl start

and was able to successfully check out the repository without error,
repeatedly.

I would rather not be running with maintainer mode, but if that's the
best solution, I'll keep doing it. I would appreciate any insight or
assistance y'all could provide.

Thanks,

Will
