From 7ffedcb97d72443c715979c8f8d8ec0b149056bb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafael=20Mendon=C3=A7a=20Fran=C3=A7a?= Date: Thu, 31 Jul 2025 23:40:39 +0000 Subject: [PATCH 1/2] Fix pin_all_from incorrectly removing "js" substring from filenames When using pin_all_from, filenames containing "js" as a substring (like "foo.jszip.js" or "bar.jsmin.js") were having the substring incorrectly removed, resulting in malformed module names like "foozip" and "barmin" instead of "foo.jszip" and "bar.jsmin". Fixed the logic to only remove the file extension from the end of the filename, preserving any "js" substrings that appear elsewhere in the name.
