Anyway the whole argument stinks. Yes filelists make transactions slower. However these particular file deps will only cause the file lists to be pulled when one of the aforementionned badly coded marginaly used games is installed or updated so 1. this won't happen for the vast majority of users or updates
Yes you're right my prior email was a bit broad, but the game packages may not be the only ones doing something of this nature with filedeps that could be avoided.
2. the costs are paid by the users of the problem packages
No, the 'costs' are paid by mirrors serving bandwidth for users with those packages installed. Yes its only the users with them installed, but the filelists are downloaded *many* more times than the offending packages (assuming in those cases it is only that game package causing the download and not the probably numerous packages with a similar problem). The filelist can be downloaded when the game causing the download is not changed and not being downloaded, so I don't see it as a direct tradeoff (correct me if I'm wrong here).
3. a single font file at gzip -9 is already more than 300K so the savings for a user that installs multiple games are not obvious 4. it's a tempest in a teacup So I really don't see what's so terrible that requires making Hans uglify its specs and reneging on our general modularization and de-duplication packaging principles.
I think what Seth Vidal's original email was looking into was a bit more of a problem than a surface issue with one or two offending game packages. But maybe it really is not that big an issue. These just happen to be packages that do highlight the issue a bit in a way that can be discussed around, and at least for me I have seen its effect.
I think it is a little bit of an issue when my rawhide boxes have pulled the filelists at least daily for awhile now... my connection is fast, but is that bandwidth really necessary? Is this idealistic de-duplication principle really that valuable in these fringe cases? If so why? For the font file case it is clearly a choice between install size vs bandwidth, so which 'costs' more?
