git tracks five scripts as mode 644 that first_time_install.sh then chmods to
755 (start_display.sh, stop_display.sh, the two install_*_service.sh, and
one-shot-install.sh does the same to first_time_install.sh). With
core.fileMode true, the default on Linux, git reports all five as modified
from then on, in files the user never touched.
The update button stashes local changes before pulling, so it is not blocked
by this. But it never pops that stash -- stash pop and stash apply appear
nowhere in the update flow -- so the mode change is stashed away and left
there, and the files revert:
=== file modes after the update button's stash ===
664 first_time_install.sh <- installer had made these 755
664 start_display.sh
664 stop_display.sh
664 scripts/install/install_service.sh
So every web-UI update silently strips the executable bit from the installer's
own scripts, and leaves a stash entry holding the difference. start_display.sh
and stop_display.sh stop working from the shell afterwards.
A manual `git pull --rebase` over SSH fails outright, since nothing stashes for
it: "cannot pull with rebase: You have unstaged changes". That is the likely
source of the reports, since plenty of people update that way.
Tracking the five as 755 -- what they should always have been, as the
installer chmodding them attests -- removes the spurious mode change
entirely: nothing to stash, nothing stripped, no stash entry, and manual
pulls work.
The pull also passes --autostash, for the case the code explicitly tolerates:
when the stash fails it logs a warning and pulls anyway, and that pull is what
then fails. Autostash also pops what it stashes, which the manual stash does
not.
Note that `git add -A` after `git update-index --chmod=+x` silently reverts
the index to the on-disk mode, so the modes here were set by chmodding the
files themselves.
Regression test asserts the five stay tracked executable; reverting any one
of them fails it.
