Public bug reported: I'm trying to use Evolution to access a 6000-vcard collection on a slow CardDAV server.
Evolution (actually the backend 'evolution-addressbook-factory') fails to read the contents of an address book stored on this slow CardDAV server. The message is "Socket I/O timed out" (after ~90 seconds). I can reliable synchronize my Android devices with this server, so the CardDAV server is working just fine. I can also access this slow CardDAV server using the Linux "cadaver" program, and just listing all 6000 cards requires about *180 seconds*. Clearly, any timeout of 180 seconds or less built into Evolution won't allow this CardDAV server to operate properly. So the problem is with Evolution. The evolution-addressbook-factory program queries this CardDAV server for a list of *all* of the contacts (i.e., all 6000 of them), which takes the server 180 seconds to return. Somewhere in the evolution-addressbook-factory code, there is a *hard- coded* timeout of something like 90 seconds. Either this hard-coded timeout should be increased to something like 5 minutes, or an option needs to be included for defining slow servers. Note that due to standard CardDAV protocols, there doesn't appear to be any way to avoid requesting and accepting the *entire list* of address cards. This is because, while evolution-addressbook-factory synchronizes at most 100 cards at a time, evolution needs to know each card's resource name (file name) when requesting a batch of 100, and the only way to do that is with a PROPFIND on the entire collection. I have tested Evolution on both x86 and x64 versions, and they both fail in exactly the same way, so the problem isn't machine-specific.
