Bug #81408 [NEW]: watchpoints don't work on powerpc64le-linux

From: bauermann at kolabnow dot com Operating system: Guix Linux PHP version: 7.4.23 Package: phpdbg Bug Type: Bug Bug description:watchpoints don't work on powerpc64le-linux Description: ------------ As part of building the php package, Guix runs the testsuite. The following tests fail on powerpc64le-linux: ===================================================================== FAILED TEST SUMMARY --------------------------------------------------------------------- Test simple recursive watchpoint [sapi/phpdbg/tests/watch_001.phpt] Test simple watchpoint with replace [sapi/phpdbg/tests/watch_003.phpt] Test detection of inline string manipulations on zval watch [sapi/phpdbg/tests/watch_004.phpt] Test proper watch comparisons when having multiple levels of indirection from a zval to its value [sapi/phpdbg/tests/watch_005.phpt] Test multiple watch elements pointing to the same watchpoint [sapi/phpdbg/tests/watch_006.phpt] ===================================================================== I'll see if I can upload the test report and individual test logs for more information. From looking at the logs, it looks like watchpoints don't work on this platform. From a very cursory look at phpdbg_watch.c, it seems that it is sensitive to the page size, which on powerpc64le-linux is 64KB. This may be a shot in the dark, but perhaps the problem is related to this? The kernel version is 5.10.0-0.bpo.8-powerpc64le (Debian's buster kernel). Expected result: ---------------- All watchpoint tests pass. Actual result: -------------- The tests mentioned in the description are failing. -- Edit bug report at https://bugs.php.net/bug.php?id=81408&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81408&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81408&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81408&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81408&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81408&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81408&r=support Expected behavior: https://bugs.php.net/fix.php?id=81408&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81408&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81408&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81408&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81408&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81408&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81408&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81408&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81408&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81408&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81408&r=mysqlcfg
