Previous daily build (1fac0276) tightened the post-STOR voidresp
handler to fail on any ftplib.Error, stopping Bambuddy from
sending a print command for a truncated 3MF. Reporter
(@enjoylifenow on a P2S) then confirmed — after a clean SD-card
filesystem check, reformat, and power cycle — that v0.2.4.1
worked on the same hardware. That proves the 426 returned by
this firmware revision is noise: the TLS data-channel close
races the 226 confirmation, server reports failure, file is in
fact on the SD card.
Reverting wholesale would re-introduce the silent-truncation
bug from the original fix. Narrow the rule instead: after an
ftplib.Error from voidresp, run an FTP SIZE against the upload
path. SIZE matches the local file size → warn and proceed
(the reporter's case). SIZE mismatch, or SIZE itself raises →
fail loudly with full diagnostics (the original tightened
behavior — preserved).
Applied identically to upload_file() and upload_bytes() so the
A1-compatibility manual-transfer path is covered.
Tests: two regressions from the previous round renamed and
split into intact / truncated / size-check-fails. Intact-file
tests inject SIZE explicitly because pyftpdlib only flushes on
a clean voidresp — which can't happen when we monkeypatch
voidresp to raise. Docstring spells that out. 87 FTP unit tests
green; 118 FTP-touching tests across unit+integration green;
ruff clean.
The View-Timelapse-greyed-out behavior #1417 was originally
about stays untouched; once the reporter confirms upload
reliability is back, that diagnosis continues on a healthy
install.
