From the daily build language pack LibreOfficeDev_24.8.0.0.alpha0_Linux_x86-64_rpm_langpack_de.tar.gz, 7z tells that the below rpm uses the xz compression method : ------------------------------ $ 7z l libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.rpm [...] Path = libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.cpio.xz Type = xz Physical Size = 16392316 Method = LZMA2:20 SHA256 Streams = 1 Blocks = 28 ------------------------------ Next, I extracted the content of this rpm package with the below command : 7z x libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.rpm This extracts the below file : libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.cpio Next I compressed this cpio archive with xz using the minimum and maximum force : ------------------------------ $ xz -1 --stdout libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.cpio > d-1.xz $ xz -9 --stdout libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.cpio > d-9.xz ------------------------------ Looking at the size of the files, it seems the rpm uses a low compression force of xz : ------------------------------ $ ls -lhS * -rw-r--r-- 1 j j 82M déc. 16 03:39 libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.cpio -rw-r--r-- 1 j j 16M déc. 16 03:39 libreofficedev24.8-dict-de-24.8.0.0.alpha0-1.x86_64.rpm -rw-r--r-- 1 j j 16M déc. 16 12:06 d-1.xz -rw-r--r-- 1 j j 3,8M déc. 16 12:05 d-9.xz ------------------------------ The memory requirement on GNU/Linux in order to use LibreOffice is at least 256MB but prefered 512MB : https://www.libreoffice.org/get-help/system-requirements/#Linux The man page of xz tells : "decompressing a file created with xz -9 currently requires 65 MiB of memory". So there is no limitation to use the maximum force ("-9") for xz compression inside rpm. Users would then be able to download rpm files faster. The servers would save storage and bandwidth. As this is a single compression for many downloads, the maximum compression force for xz would provide an overall benefit.
Thanks Jérôme. Same as for bug 158732, waiting for input from Cloph or Xisco (or any other savvy packager) on how doable that is for our installers and if there's any reason we shouldn't.
Dear Jérôme, To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year. There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present. If you have time, please do the following: Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/ If the bug is present, please leave a comment that includes the information from Help - About LibreOffice. If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice. Please DO NOT Update the version field Reply via email (please reply directly on the bug tracker) Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not appropriate in this case) If you want to do more to help you can test to see if your issue is a REGRESSION. To do so: 1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/ 2. Test your bug 3. Leave a comment with your results. 4a. If the bug was present with 3.3 - set version to 'inherited from OOo'; 4b. If the bug was not present in 3.3 - add 'regression' to keyword Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa Thank you for helping us make LibreOffice even better for everyone! Warm Regards, QA Team MassPing-UntouchedBug
I confirm this bug still exists with the version 25.8.4.2 Linux x86-64 that I downloaded today.
