From: Daira Hopwood Date: Wed, 30 Sep 2015 15:22:40 +0000 (+0100) Subject: Rename did_upload_file to did_upload_version, and is_new_file_time to is_new_file. X-Git-Url: https://git.rkrishnan.org/%5B/%5D%20/uri/provisioning?a=commitdiff_plain;h=cd8dcb3c5ffb1277d56366a6e049714859927e0e;p=tahoe-lafs%2Ftahoe-lafs.git Rename did_upload_file to did_upload_version, and is_new_file_time to is_new_file. Make them take a PathInfo argument rather than (mtime, ctime, size). Also treat the size of a nonexistent file as None (SQL NULL) rather than 0.
