Dear FTP Masters, As of Reposurgeon 4.0, the Python-to-Go conversion has been completed with major performance improvement. However, as Debian buildd results for 4.2-1 show, reposurgeon no longer builds on 32-bit architectures: https://buildd.debian.org/status/logs.php?pkg=reposurgeon&ver=4.2-1 I inquired upstream at https://gitlab.com/esr/reposurgeon/issues/255, and author Eric S. Raymond @esr replied: I haven't bothered to keep the code 32-bit-compatible because 4GB isn't enough address space for medium to large large repository conversions. The manual page already says: Because the code is designed for dealing with large data sets, it has been optimized for 64-bit machines and no particular effort has been made to keep it 32-bit clean. Various counters may overflow if you try using it to lift a large repository on a 32-bit machine. When Julien Rivaud suggested replacing int by int64 throughout the code, Eric further replied: @frnchfrgg Unfortunately changing int to int64 would be more of a pain than you've perhaps realized yet. Range clauses and various system-library things are wired to int; we'd have to add an annoying number of castS and var statements to fix that. I don't think it's worth the complexity increment. After fifteen years of adverse selection, repositories small enough not to blow out a 4GB limit but not already converted are increasingly rare, meaning that a true 32-bit build is not much good for anything but passing its own regression tests. I wrote about the adverse-selection effect in 2014: http://esr.ibiblio.org/?p=6216 Soon after, Eric updated the INSTALL documentation https://gitlab.com/esr/reposurgeon/-/blob/master/INSTALL.adoc: You will need 64-bit hardware. This code is not intended to run on 32-bit machines (which have an address space too small to be useful for repository surgery) and won't build on them. So, I went ahead to remove [armel armhf i386 mipsel] from Architecture list in debian/control: See https://salsa.debian.org/debian/reposurgeon/commit/5f8db4c And proceeded to file this Bug report to you so as to allow reposurgeon to be migrated to testing. Many thanks!
