Description
Quoting from my mail to the dev list: > Trying to help someone on IRC today, I imported the linux kernel source into a > repository. I then tried to check it out over dav and had problems. After > watching for a while, I noticed that whenever the checkout started a new > directory it would stop for quite a while, and the httpd memory usage would > grow. I soon found out that my svn client would time out before getting a > PROPFIND request back for the include/linux directory of the kernel sources. > > The reason for this is that my machine starts thrashing, because the httpd > process trying to do the propfind grows huge (680MB before I killed it).(Note > by contrast that opening the directory in w3m took about 2 seconds, and I > didn't notice httpd's memory usage. > > Tracing into this I found that mod_dav opens and closes it's internal prop > database for every resource found. I don't claim to know enough about the > internal workings of mod_dav to fix it, but thought I would post it here to > get gstein's attention when he gets back. Also note that it is not the call to svn_fs_dir_entries that is the problem since dav_svn_deliver has the same call, but not the same problems. Sander thinks it may be the recursive loop just below (we're talking mod_dav_svn/repos.c:1963). He's testing a fix right now, so hopefully this issue will be quickly closed.
