Build docker image and push to registry.bitdeals.org / main-build-job (push) Successful in 2m42s
The startup VACUUM of a large messages.dat exceeds the stock 60 s window, and PyBitmessage then kills the daemon (os._exit). Since it dies mid-VACUUM lastvacuumtime is never updated, so every later start repeats it and the node stays down with its API not listening.

# PyBitmessage kills the daemon outright if the SQL thread is not ready within
|
|
# sql_timeout seconds (class_objectProcessor.py -> os._exit(1)). The startup
|
|
# VACUUM of a messages.dat that has grown to a few hundred MB does not fit in
|
|
# 60 s, and since the process dies mid-VACUUM lastvacuumtime is never updated,
|
|
# so every later start retries the same doomed VACUUM and the node never comes
|
|
# back. Measured: 26 s for a 264 MB database on an idle host, and the last
|
|
# start that did survive used 36 s of the 60.

# The greps are load-bearing: the clone above is unpinned, so if upstream ever
|
|
# moves or renames the constant, a silent no-op sed would ship an image that
|
|
# looks fixed and is not. Fail the build instead. The .pyc is refreshed because
|
|
# at runtime /usr/local is root-owned while the daemon runs as bitmessage, so a
|
|
# stale one can only be recompiled to memory on every start.
