This INDEX based binary package management hasn't really been done before. kports can do it, pkg_upgrade does it, and I am told portmaster now can do it, too. There's a big wishlist of stuff to go into INDEX. The gist of the whole thing is, that binary package management ever was an intention, and all infrastructure in place has not been exposed to practical use before. That's why the next version of pkg_upgrade will come with its own INDEX generator, so people can generate a more useful INDEX for their own package builds. Additional data can be stored in separate files as long as there is some way to verify they all belong to same build. It could be some information in header (does INDEX support comments?) or some assumption such as that modification times may not differ by more than a couple of seconds (just touch them all at the end of build). I think storing all columns in separate files would be better and allow future extensibility. For example consider PKGINDEX subdirectory with following files, each having one entry per line: ...

You can then operate on them using utilities like join(1) and tsort(1). I think I'll make use of your idea to create separate files and work with join, provided that the performance suffices. I expect your way to be faster, when memory is scarce. So especially useful to update packages on an ALIX or a similarly limited machine. I will build my INDEX directly from the present packages, though. This would be the most reliable way, I assume. -- A: Because it fouls the order in which people normally read text.

Thinking a bit more, even *that* won't save you from broken system at the end of upgrade as it happened to me yesterday since packages keep their versions when rebuilt with different incompatible dependencies. Awww crap, whole package thing on FreeBSD is broken by design :( I guess the only possible fix for upgrades in the middle of mirroring would be to have completely immutable repositories with timestamp in their name and then some file that points to latest complete repository. Older repositories could be deleted after some time. Actually there are even programs based on rsync (liek rsnapshot) that do something similar. ___ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to freebsd-ports-unsubscr...@freebsd.org

Unfortunately no scheme involving global lock files will really work. I've read http://wiki.freebsd.org/FreeBSDMirrors that you linked and it mentions TIMESTAMP files that it uses to monitor mirrors quality. You just need to visit $random[1] freebsd mirror and look at that file then check packages directory. You will find that it can have latest timestamp yet many months old files. In other words, mirrors cannot be trusted. For now however I've found and suggested in sibling post a workaround that should mostly work assuming INDEX file gets mirrored before packages (and it looks like it is). [1] random = ftp.pl.freebsd.org, but it's not the only one One might also want an optional force- fetch- regardless flag. Awkward conditions to allow for: What if mirror is not mirroring when you start your fetch, but is when you finish ? What if mirror is not mirroring when you start your fetch, then mirror starts finishes a mirror before you finish your fetch ? Solving any of this, in a way that does not require intervention of user if it happens, requires that file content at given url is immutable (or doesn't exist). There is simply no other 100% reliable way. You can however do some sanity checks and fail early if failing is acceptable. Some ideas: 1. if (mtime(pkg) mtime(INDEX)) fail(Mirror sync in progress); 2. Fetch timestamps of all requested packages in one go before fetching contents; do it again and compare to be sure nothing changed; fetch actual packages and fail if mtime/size does not match. 3. Do 1 or 2 but fetch timestamps from well known source or multiple sources. You may also find most up-to-date mirror this way.
