IIS does not set X-Forwarded-For on its own and HttpPlatformHandler connects
from loopback, so without a rewrite rule every client reads as 127.0.0.1. The
GE-Enforce IP allowlist, the dashboard visitor-location lookup and per-host
login rate limiting all stop working, silently. The rule needed URL Rewrite,
which the installer told operators to download - from an air-gapped server.
URL Rewrite now ships in the bundle, and the wizard asks which case applies,
because the two answers are mutually exclusive. Directly exposed: install it and
set X-Forwarded-For from REMOTE_ADDR, which is what stops a client spoofing its
own. Behind a proxy: leave the rule off, since REMOTE_ADDR is the proxy and
applying it would discard the real client IP.
The rule is enabled by deleting two explicit marker lines rather than by a regex
over the surrounding comment, so editing that prose cannot silently disable it.
An existing web.config is no longer overwritten. It is the one file on a server
that legitimately carries hand-edits, and replacing it reverted them without a
word - on a server where the X-Forwarded-For rule had been enabled by hand, that
alone would have turned the GE-Enforce IP allowlist off. The installer reports
what it found instead.
pip now runs with --require-hashes and --only-binary=:all:. Hash-checking is
requested explicitly rather than inferred from the lockfile, so shipping an
unhashed requirements.txt fails loudly instead of quietly dropping the check.
shopdb-admin.ps1 gains a verify command: which bundle this server was installed
from, and whether the installed packages still match what shipped.
The .iss states its compiler floor. WizardStyle uses the built-in windows11
custom style, which needs Inno Setup 6.6.0; older compilers now fail with that
sentence rather than 'WizardStyle is invalid'.
The bundle carries ~40 wheels, a Python installer and two MSIs. All of them run
as SYSTEM on the target server, and nothing verified any of them. A missing
wheelhouse printed MISSING and the script still exited 0, so an empty bundle
compiled into a shippable installer and the failure surfaced on an air-gapped
server with no way to fix it.
bundle-lock.json now records that payload exactly - sha256 and byte size per
file - and verification is set equality: a missing file, an unexpected extra
file, or changed content all fail. Both builders check it and refuse to produce
an unverified bundle; the lock ships inside the bundle and shopdb-install.ps1
re-checks it on the server before running any of it.
This is deliberately a layer above requirements.txt hashes. pip lists every
artifact of a pinned version (cffi 2.1.0 alone has 100 hashes), so it proves a
wheel is genuine, not that it is the wheel this bundle was built and tested
with; it ignores extra files in the wheelhouse; and it covers none of the
executables.
refresh-bundle-lock.ps1 regenerates the lock but refuses to overwrite one until
the operator has seen the diff, because the commit is the review - it is the
only place a change to what runs as SYSTEM becomes visible to a human.
build-installer.ps1 is the whole build natively on Windows, so a work PC needs
no Bash. It shares the plugin closure resolver with build-site.sh.
Both builders now copy the installer scripts from the repository. They were
copied from a downloads folder, so the logic that shipped was not the logic that
was committed and the build worked on exactly one machine.
Two verifiers exist because PowerShell is the only thing guaranteed present on
the target server, while the Linux builder should not need pwsh.
tests/test_bundle_lock.py runs both against the same fixtures and fails if they
disagree.
Roughly 2500 lines of tested installer had been living in ~/Downloads and an
untracked folder - nothing was under version control.
It goes here rather than in a repo of its own because it depends on application
internals: the `flask plugin` verbs, site-profile.json, MOUNT_PATH, and the
plugin registry. Versioned separately it would drift out of step with the thing
it installs.
Contents: the read-only preflight, the staged installer (bundled MySQL, runtime,
schema, IIS, verify, uninstall), the operator console, the Inno Setup wizard, the
bundle builder and the artwork generator.
bundle/ and Output/ are ignored - regenerable, and ~220MB. plugins.iss is ignored
because build-installer.sh generates it from the staged payload. The artwork IS
committed so a Windows build box does not need Python and cairosvg.
Verified end to end on Windows Server 2025 against a bundled MySQL 8.0 and an
existing MySQL 5.6: fresh install, upgrade with backup and rollback, re-run
idempotency, uninstall, and both deployment methods including switching between
them. Not yet verified: a hypervisor-level air-gapped run, and any load from a
real browser (every HTTP check so far used curl, which sends no Origin header).
