01:12:54 <pjustice> More specifically, the function-entry and function-return probes don't seem to do anything.
08:59:56 <nikolam> Khm, something is wrong here. I am trying to upgrade platform image on USB flash, for booting Standalone SmartOS install. And I get wrong MD5 checksum.
09:01:06 <nikolam>  https://us-central.manta.mnx.io//Joyent_Dev/public/SmartOS/20140111T020931Z/md5sums.txt says b4d64f93dc51d58adb72fcdcfa27ec37 and https://us-central.manta.mnx.io/Joyent_Dev/public/SmartOS/platform-latest.tgz is 07e9cc65431502a31b4bde667a156938 per digest -a md5 , after download.  
09:01:57 <nikolam> Following https://docs.smartos.org/remotely-upgrading-a-usb-key-based-deployment/ for USB flash nott drive update
09:02:41 <nikolam> Maybe something is not updated on release
09:08:37 <nikolam> oh I forgot i need to change release number.. when downloading md5sums.txt.. sorry silly me
09:10:01 <nikolam> So the link for latest release is https://us-central.manta.mnx.io//Joyent_Dev/public/SmartOS/20251002T000521Z/md5sums.txt
10:08:56 <jperkin_> pjustice: it looks like it has deteriorated over time, php56 fires on all the probes, php74 fires on startup and errors but not on function calls, and php8+ only fires on startup
12:39:02 <jperkin_> pjustice: digging further into the source code, for some reason they've now moved it behind a check for a USE_ZEND_DTRACE environment variable, and sure enough if that's set then the function probes work again
12:50:23 <jperkin_> https://github.com/php/php-src/commit/0c78fe4bb55a9d39afc79cbcbadb9a273f2ec2ef - the whole point of dtrace probes is that they only cost when enabled, so this suggests they are doing something wrong, but at least there's a workaround
13:15:46 <pjustice> Thanks!
21:19:42 <neirac> nikolam Are you still getting a wrong MD5 checksum?
