Description of problem: After updating deltarpm to 3.6.1 previously created gzip deltarpms can no longer be applied. Version-Release number of selected component (if applicable): 0:3.6-1.fc19 How reproducible: Every time Steps to Reproduce: 1. Install deltarpm 3.6 1. Build 2 gzip rpm packages. 2. Build deltarpm for them 3. Run applydeltarpm to verify. 4. Update deltarpm to 3.6.1 5. Run applydeltarpm again Actual results: md5 mismatch Expected results: Successful creation of deltarpm Additional info: There is no corresponding 3.6.1 update for rhel, so gzip deltarpms created there cannot be applied on Fedora.
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
Sorry for the delay in replying. Just to be clear, we do not support applying deltarpms created with a different version of the compression library. Deltarpm didn't change any code in its gzip using in the 3.6 update. The problem is that gzip doesn't make any guarantees about byte-for-byte identical files which is what deltarpm requires. When the gzip library changes, there is a non-zero chance that old deltarpms will no longer work, and there's not much we can do about that.
Thanks for taking the time to follow up on the EOL bugs. I filed this originally because I suspected a change in deltarpm itself (probably https://gitorious.org/deltarpm/deltarpm/commit/e8f82b5d9014085d3cd63a5dc1332061e106b3c1) was the cause. Too late to do anything about it now anyway.
