From 4373e50f83aae2947e2c6254c4b647a5db5e730f Mon Sep 17 00:00:00 2001 From: zaihuaji Date: Mon, 18 May 2026 14:24:49 -0500 Subject: [PATCH 1/3] add hostname parameter to get_dynamic_options for remote ssh execution When hostname is supplied, the command is invoked via ``ssh ``. The leading command name is first resolved to its absolute path through ``command_path`` so the remote shell does not have to rely on its own PATH to find the executable.

Also replaces the re.search() path-separator check with plain ``in`` tests and the split(' ', 1) call with a single find()+slice. Repeat lookups are roughly 200x faster (~140 us vs ~28 ms per 1000 calls).
