The tests are driven by runtests.py. installcheck appears to be suitable for a ptest implementation because it runs against an installed rsync binary ($(bindir)/rsync). The testsuite requires helper programs listed in CHECK_PROGS (tls, getgroups, getfsdev, testrun, trimslash, t_unsafe, wildtest, simdtest). Initial investigation suggests ptest support is feasible. 105681 2 nikhilar2410 2026-05-31 14:59:02 +0000 I have been working on adding ptest support for rsync. I have implemented ptest support for rsync and tested it on qemux86-64. A representative successful run shows: root@qemux86-64:~# ptest-runner rsync START: ptest-runner 2026-05-31T14:06 BEGIN: /usr/lib/rsync/ptest ============================================================ runtests.py running in /usr/lib/rsync/ptest rsync_bin=/usr/bin/rsync srcdir=/usr/lib/rsync/ptest TLS_ARGS=-l -L testuser=root os=Linux qemux86-64 6.18.33-yocto-standard #1 SMP PREEMPT_DYNAMIC Wed May 27 22:05:49 UTC 2026 x86_64 GNU/Linux preserve_scratch=no scratchbase=/usr/lib/rsync/ptest/testtmp PASS 00-hello PASS acls-default PASS acls PASS alt-dest PASS atimes PASS backup PASS batch-mode PASS chgrp PASS chmod-option PASS chmod-temp-dir PASS chmod PASS chown PASS clean-fname-underflow SKIP crtimes (Rsync is configured without crtimes support) PASS daemon-gzip-download PASS daemon-gzip-upload PASS daemon PASS delay-updates PASS delete PASS devices PASS dir-sgid PASS duplicates PASS exclude-lsh PASS exclude PASS executability PASS files-from PASS fuzzy PASS hands PASS hardlinks PASS itemize PASS longdir PASS merge PASS missing PASS mkpath PASS open-noatime PASS protected-regular PASS relative PASS safe-links PASS simd-checksum PASS ssh-basic PASS symlink-ignore PASS trimslash PASS unsafe-byname PASS unsafe-links PASS wildmatch PASS xattrs ------------------------------------------------------------ ----- overall results: 45 passed 1 skipped ------------------------------------------------------------ overall result is 0 DURATION: 91 END: /usr/lib/rsync/ptest 2026-05-31T14:08 STOP: ptest-runner TOTAL: 1 FAIL: 0 45 passed 1 skipped (crtimes) overall result is 0 The skipped test is expected because rsync was configured without crtimes support. To assess stability, I executed the ptest repeatedly on qemux86-64. While most runs completed successfully with the above result, I also observed intermittent failures in backup.test. Over 20 runs, backup.test failed 5 times. The failure alternates between: no backup message output for deep/name1 and no backup message output for deep/name2 Example failure output: >f.s....... deep/name2 backed up deep/name2 to deep/name2~ no backup message output for deep/name1 All other tests pass consistently. At this point the ptest packaging appears functional and the remaining issue seems limited to the intermittent behavior of backup.test in the qemux86-64 environment. 105682 3 randy.macleod 2026-05-31 19:00:50 +0000 Nikhil, Excellent work! I particularly like that you have run the ptests 20 times to look for intermittent issues before it gets tested on the Yocto auto-builder. I suggest that you add a patch/filter to skip the intermittently failing backup test and report that up upstream to get to the root cause. Check rsync's development work at: https://github.com/RsyncProject/rsync.git You can either submit that to the oe-core email list or wait a week to see if upstream can explain/fix the bug. I don't think you need this link but in case other people who do are following along: https://docs.yoctoproject.org/contributor-guide/index.html Thanks. 105684 4 nikhilar2410 2026-06-01 06:16:27 +0000 Hi Randy, I have reported the bug upstream https://github.com/RsyncProject/rsync/issues/941 Will add a patch/filter to skip the intermittently failing backup test and send it to oe-core email list. Will keep a track on the upstream issue as well. Thanks 105691 5 nikhilar2410 2026-06-01 16:59:15 +0000 Submitted a patch in oe core https://lists.openembedded.org/g/openembedded-core/message/237969
