Description of problem: Hi - Is yum-presto known to work on arm? Today I changed our repo to use deltarpms and tested it out. I noticed... 1) On a package where I know the bulk of the unpacked data is some fonts inside an ELF executable that didn't change, the compression result was... not good Old RPM: 25424385 txtr-reader-0.1-417.fc11.armv5tel.rpm New RPM: 25465487 txtr-reader-0.1-420.fc11.armv5tel.rpm Delta RPM: 25465402 txtr-reader-0.1-417.fc11_0.1-420.fc11.armv5tel.drpm So it saved me 85 bytes from 25MByte :-) The actual procedure here is the createrepo is run on an x86_64 box over these arm packages and then rsync'd on a server. 2) Using deltarpms fails Loaded plugins: presto Setting up Update Process Resolving Dependencies There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them. --> Running transaction check ---> Package txtr-reader.armv5tel 0:0.1-420.fc11 set to be updated --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Updating: txtr-reader armv5tel 0.1-420.fc11 txtradevel 24 M Transaction Summary ================================================================================ Install 0 Package(s) Update 1 Package(s) Remove 0 Package(s) Total download size: 24 M Downloading Packages: Setting up and reading Presto delta metadata Downloading DeltaRPMs: Rebuilding rpms from deltarpms /var/cache/yum/txtradevel/deltas/txtr-reader-0.1-417.fc11_0.1-420.fc11.armv5tel.drpm: md5 mismatch of result Error rebuilding rpm from txtr-reader-0.1-417.fc11_0.1-420.fc11.armv5tel.drpm!

Any advice welcomed, it would be great to reduce this 25MByte package down since the vast bulk of it is exactly the same each time :-) -Andy -- fedora-devel-list mailing list fedora-devel-list https://www.redhat.com/mailman/listinfo/fedora-devel-list Version-Release number of selected component (if applicable): How reproducible: Fully Steps to Reproduce: See above Actual results: huge deltarpm, failed deltarpm regeneration Expected results: tiny deltarpm, happy regeneration Additional info: It's on an ARM11 iMX31 device
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

This seems to be working now (I'm able to get deltarpms on my Raspberry Pi).
