When using boinc-wrapper for anonymous platform boinc projects (e.g. sci-misc/cmdock), any update which changes the size of /usr/bin/boinc-wrapper causes new jobs to fail and all jobs to be lost upon restart. [SiDock@home] File projects/www.sidock.si_sidock/cmdock-l_wrapper has wrong size: expected 1474184, got 543984 This happens because boinc-client validates the size of files in each project directory, and it follows the cmdock-l_wrapper -> ../../../../../usr/bin/boinc-wrapper symlink while doing so. At this point, boinc-client detects a size mismatch and deletes the symlink which causes all future jobs to fail. Reproducible: Always Steps to Reproduce: 1. Use boinc-wrapper with a project like cmdock 2. Start some jobs in boinc-client 3. Change the size of /usr/bin/boinc-wrapper 4. Wait for a new job to start and observe the error message Workaround 1. Stop boinc-client. 2. Update boinc-wrapper. 3. Manually edit /var/lib/boinc/sched_request_www.sidock.si_sidock.xml and change the cmdock-l_wrapper <nbytes> entry to the new size. 4. Start boinc-client. Potential solutions 1. In boinc-app.eclass generate a wrapper script instead of a symlink, something like #!/bin/sh exec "${EPREFIX}/usr/bin/boinc-wrapper" "\${@}" This script should never (almost never) change size so boinc-client will not notice any difference. This is what I do in my custom cmdock ebuild - https://github.com/piedar/overboard/blob/a7972f8b8dcfc1042f307b62a79554ad4323413d/sci-biology/cmdock/cmdock-0.2.0-r15.ebuild#L252 2. OR convince upstream to avoid following symlinks when validating file sizes.
Shell wrapper seems like a good solution, eclass update sent for review. https://marc.info/?l=gentoo-guru&m=172907433029987&w=2
