Profile of one upgrade in a scratch journal, one changed file: of 6.7 s, pack 4.2 (compiling every file 1.5, starting the built archive to prove it boots 1.8), refreshing the package 1.1 (copies all 813 files), configure 1.2; and on a copy of the real 279 MB record the record backup alone (keep_copy, tar.gz of the whole record before every upgrade) was 10-11 s CPU and 17-54 s wall at load 55, the bulk of the 29-76 s. Changes: (1) the pack reuses the previous archive's entries (source, compiled bytes and stamp) for every file whose source is unchanged and compiles only the rest (and compiles with a stable name, .journal/journal.pyz/<name>); (2) the copy of the record is made only when a migration is pending (the only thing that changes the record; migrations also take their own in-place backup), moved into finish() just before the migrations so the new code can say so, and the check costs nothing otherwise; (3) when it is made it is not compressed (tar.gz at level 0: 6.5 s wall, 3.4 s CPU for 190 MB, against 17.9 s wall at level 1 and 26.7 s at the old level 9 for 107 MB), and (4) it is not made again when the last copy is under an hour old. 'Preparing the update' no longer holds the copy at all. Measured before and after, same scratch journal, upgrade with one changed file, repeat runs: before 4.7-4.9 s wall and 2.5-2.7 s CPU, after the pack change 3.6 s wall and 1.8 s CPU (the scratch record is tiny, so the copy saving comes on top and on your record is the big one: no migration, no copy: about 17 s of wall and 10 s of CPU gone per upgrade). Tests run: src/features/auto_update/test.py 10 passed (pack compiles only what changed and keeps the other entries; no copy without a pending migration, one when migrating; a fresh copy is not made again); tests/test_it_boots.py with starting_agents and plugins: 85 passed, 2 failed in the first run: test_the_first_hooks_after_an_upgrade... was mine (it still patched the removed code_mark from 3768, now shape_mark; it passes) and test_the_chat_mirror_replays_what_was_left_unsent... is not from this change: runner.chat_mirror has no replay since commit 49ada54d0 (the spool for hook events), whoever owns that needs to move the test. Also src/features/plugins/test.py::test_a_chosen_setting_reaches_the_plugins_commands fails on main with 'byte indices must be integers': the dashboard now answers held bytes (commit d4f87d860).
