So for 2.1, I've got a candidate solution in my github repository in a branch called "21_largefile_support". It makes it so that libevent itself is always built with large-file support, but that its headers never use the platform off_t (as discussed in my last email). It could use review! This shouldn't actually break applications that don't use largefile support, since their value of off_t won't affect anything. Applications that need to use 2.1 will need to get recompiled anyway: 2.1 _is_ free to break ABI compatibility until it's stable. We can't do this easily in 2.0, though, since 2.0 doesn't have the evconfig-private.h mechanism to add in build options, and since changing the type of ev_off_t would break binary compatibility. I'm not so sure that this is worth breaking binary compatibility for in a stable release. -- Nick *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
