      @icedquinn recently had to extract .tar.bz2 and had to look up what flag is used for it instead of -z (it's -j)

      @hj @icedquinn
      I use bzip2 a lot — it takes me more time to recall whether xz is uppercase J or is it Z 😂
      XZ offers superior compression, but it's also significantly more resource-hungry — this isn't what I'd use on an old ARM machine with half a gig of RAM.

        XZ Utils backdoor
        On 29 March 2024, software developer Andres Freund reported that he had found a maliciously introduced backdoor in the Linux utility xz within the liblzma library in versions 5.6.0 and 5.6.1 released by an account using the name "Jia Tan" in February 2024. While xz is commonly present in most Linux distributions, at the time of discovery the backdoored version had not yet been widely deployed to production systems, but was present in development versions of major distributions. The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution capabilities on the affected Linux system. The issue has been given the Common Vulnerabilities and Exposures number CVE-2024-3094 and has been assigned a CVSS score of 10.0, the highest possible score. Background Microsoft employee and PostgreSQL developer Andres Freund reported the backdoor after investigating a performance regression in Debian Sid. Freund noticed that SSH connections were generating an unexpectedly high amount of CPU usage as well as...

      @mia@movsw.0x0.st @icedquinn@blob.cat my bad, that was an unfinished thought. from the current dpkg-deb manpage, the utility that glues a package together:

      ```
      -Zcompress-type
      Specify which compression type to use when building a package.
      Allowed values are gzip, xz (since dpkg 1.15.6), zstd (since
      dpkg 1.19.0.5ubuntu2) and none (default is zstd).
      ```
      they are cpio archives with any of the above compression, and the archive itself can ofc contain whatever pre-compressed files you desire.

      in the Pentium II days, debian did skip over bzip2 for packages and it was due to the extreme memory requirements it demanded when the decision was made. anyone with less than ~64MB of RAM wouldn't have been able to install it, which would have excluded a huge chunk of hobbyists at the time.

      by the time they got around to considering adding bzip2, xz had come along and was better in every way.

      off topic, but, i'd like to see them add parallel decompression in dpkg-deb 👉👈

      @purple @icedquinn so is .rpm; doesn't mean the tools necessarily support any compression method

      @icedquinn interestingly i think debian never supported bzip2

      it just went gzip → sleepy_graybeard.jpg → xz → zstd (the latter two only due to ubuntu)

      @mia@movsw.0x0.st @icedquinn@blob.cat i routinely run in to the problem a package manager trying to restart a service that 1: doesn't need to be restarted and 2: refuses to come back up cleanly because the other packages it depends on hasn't been updated yet.

      find me a package manager that solve that and i'll switch immediately. hell, i'll join the dev team.

      @purple @icedquinn there are some cases where restarts can fail but ime it's always a packaging issue

      restarts can also be disabled with a global setting but that's opensuse-specific. zypper/libzypp can show processes that are still using outdated libraries plus their systemd units as well. I'm using its python module in a script that does some extra work and selective restarts on my system

      @mia@movsw.0x0.st @icedquinn@blob.cat mmmmm i made the mistake of using the source. they've come full circle. it's now tar archives.

      https://salsa.debian.org/dpkg-team/dpkg/-/blob/main/src/deb/build.c?ref_type=heads#L468

      90% sure you could pass it bzip2 and it wouldn't even bitch, just be undocumented lol
