cacti_exec() read proc_get_status()['exitcode'] after the child exited. On PHP 8.0-8.2 that field is -1 until proc_close() is called; PHP 8.3 fixed the behaviour. push_out_hosts.php calls cacti_exec() on --help and forwarded the -1 as exit(-1), causing FAILED=4 in the harness. Replace with proc_close(), which returns the correct status on all supported PHP versions. Also fix the --list-host-templates probe: add_device.php is in cli/, not the workspace root.

Line numbers in lib/functions.php shifted by one (single proc_close removed in previous commit), which caused both sink_inventory and architectural_hotspots baselines to diverge. Regenerated both. Replace the single-shot apt-get update/install with a 5-attempt retry loop (20-80s backoff). Acquire::Retries alone does not cover connection- refused failures from the ondrej/php PPA; the outer loop re-runs apt-get update before each package install retry so the index is fresh.

setup-php already runs apt-get update when it adds the ondrej/php PPA. Running a second update after the PHP install step re-fetches all source lists; if the PPA is temporarily unreachable, apt marks those packages as unavailable and the libapache2-mod-php install fails with E: Unable to fetch packages, even though the packages were already resolvable. Skip the redundant update and install from the cached lists that setup-php left in place. Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>
1.2.x targets PHP 7.4 as its runtime. Testing PHP 8.0-8.4 was out-of-scope and causing flaky failures against the ondrej/php PPA for libapache2-mod-php8.x packages. Narrow the matrix to the one version that matters. Signed-off-by: Thomas Vincent <thomasvincent@gmail.com>

…e device writes api_plugin_moveup()/movedown() skip the reorder when MAX()/MIN() returns NULL on an empty set (avoids a NULL->0 primary-key corruption), tree sort helpers bail when the branch row is missing, and discoverDevices() uses prepared statements for the automation_devices writes.

Closing as redundant: current 1.2.x already contains both the api_plugin_moveup()/movedown() NULL guards and the tree sort-type guards this PR proposed (verified against the 1.2.x tip). Superseded upstream. |
