How it Works

Project Forge WMS technical and operational architecture

1. Purpose and Deployment Model

System Update installs an approved Project Forge WMS GitHub Release on a staging or production server. It downloads a packaged, checksummed release. It does not run git pull, require a Git working tree, copy staging files to production, or invoke Plesk Git deployment.

Developer → Git tag → GitHub Release → Staging → Production

Staging and production independently download the same immutable release assets from GitHub.

2. Major Components

Component	Responsibility
httpdocs/manifest.json	Application version, numeric build, requirements, database version, release date, and release notes.
.github/workflows/project-forge-release.yml	Validates the tag, builds the ZIP, calculates SHA-256, and creates a GitHub prerelease.
httpdocs/modules/system_update/	Administrator UI, AJAX endpoints, release discovery, validation, installation, backup, and status.
ScheduleScripts/system_update.php	CLI worker that claims and executes one queued update job.
system_jobs	Stores queued, running, completed, and failed jobs.
APP_ROOT/storage/system_updates/	Private downloads, extraction, backups, locks, logs, and installed-file inventory.
APP_ROOT/config/system_update.php	Private channel and GitHub token shared by web PHP and the CLI worker.

3. Release Channels and Immutability

Channel	Eligible releases	Use
staging	Non-draft prereleases and stable releases	Test before production approval.
production	Non-draft stable releases only	Install explicitly promoted releases.

Every new tag is published as a prerelease. After staging installs and approves it, an operator edits the same GitHub Release and clears its prerelease flag. Promotion must not create another tag, rebuild the ZIP, replace an asset, or change the checksum.

4. Check for Updates

1. The browser calls modules/system_update/ajax/check_update.php.
2. The endpoint validates the local manifest.
3. The GitHub Releases API is queried using the private token.
4. Drafts and releases disallowed by the configured channel are removed.
5. The updater requires an exactly named ZIP and SHA-256 asset.
6. The remote manifest is validated and compared with the local manifest.
7. Update is enabled only when a valid newer release is identified.

A release is newer when its numeric build is greater, or when builds tie and its semantic version is greater.

Read-only: Check for Updates does not modify files or queue installation.

5. Queue, Monitor, and Execute

1. ajax/start_update.php validates POST, authorization, CSRF, tag, channel, and concurrency.
2. It creates a system_update job with status queue.
3. The browser polls job_status.php. Polling only reads status; it does not execute the job.
4. Plesk runs ScheduleScripts/system_update.php.
5. The worker atomically claims the job and executes the update service.

Plesk: use Scheduled Task type Run a PHP script, not Run a command. Command tasks are chrooted and may not contain PHP.

Script: ScheduleScripts/system_update.php
PHP: 8.5
Schedule: * * * * *

6. Installation Phases

Phase	Operation
download	Resolve metadata and download ZIP/checksum using authenticated GitHub asset API URLs.
verify	Compare ZIP SHA-256 with the published checksum.
extract	Reject traversal, absolute paths, unsafe links, and size/count violations; extract privately.
preflight	Validate runtime, protected paths, storage placement, package layout, disk space, and migrations.
backup	Back up managed overwritten/removed files and record new files.
install	Overlay managed files and remove only obsolete files proven by a trusted inventory.
migrate	Run pending SQL migrations when present.
post-update	Verify required files and installed manifest; write new inventory.
cleanup	Remove temporary data and release the lock.
complete / failed	Record terminal state and administrator message.

7. Security Controls

• Token and channel are stored outside httpdocs and never returned to the browser.
• Updater storage must resolve outside DOCUMENT_ROOT.
• Downloads require HTTPS, approved GitHub hosts, authenticated asset API URLs, and approved redirect hosts.
• SHA-256 is verified before extraction.
• CSRF is mandatory for the update POST.
• Atomic job claiming and a lock prevent concurrent installation.
• Configuration, uploads, attachments, environment files, storage, logs, and backups are protected.

The private configuration file returns this array:

return [
    'channel' => 'staging', // production on production
    'github_token' => 'TOKEN_VALUE',
];

Recommended private-config mode: 0640, owned by the website user and subscription group.

8. Storage and Logs

APP_ROOT/config/system_update.php
APP_ROOT/storage/system_updates/downloads/
APP_ROOT/storage/system_updates/extracted/
APP_ROOT/storage/system_updates/backups/
APP_ROOT/storage/system_updates/locks/
APP_ROOT/storage/system_updates/logs/
APP_ROOT/ScheduleScripts/system_update.php

Job logs use storage/system_updates/logs/{job_id}.log.

9. Backup and Recovery Limits

Before migrations start, rollback attempts to restore overwritten files, remove newly created managed files, and restore obsolete managed files removed during installation.

Database: updater file backups are not database dumps. SQL migrations are not automatically rolled back and may partially apply. A verified external database backup and recovery plan are required before migrations.

10. Definition of Success

• Job status is done and phase is complete.
• Local manifest equals the installed release version and build.
• A new check no longer offers the installed release.
• Protected paths and private configuration remain unchanged.
• Critical WMS smoke tests pass.
• The installed artifact checksum equals the approved GitHub checksum.

Developer Release and Deployment Guide

Local development → repository → staging → testing → production

1. Approved Release Flow

1. Develop and test changes locally.
2. Commit source changes to main.
3. Update manifest.json and commit the release.
4. Push a final version tag.
5. GitHub Actions builds one immutable ZIP/checksum pair as a prerelease.
6. Staging independently installs and tests that prerelease.
7. Promote the same GitHub Release by clearing only its prerelease flag.
8. Production independently installs the same asset.

Never: copy files from staging to production, rebuild during promotion, create a second production tag for the same release, or use Plesk Git deployment to install a release being tested through System Update.

2. New Server Installation

Complete this section once for every new staging or production installation. The updater cannot install its own missing foundation, so the initial application and System Update files must be deployed through Plesk Git.

2.1 Register the Plesk SSH deploy key

1. In Plesk, open the domain and create a Git repository from a remote repository.
2. Use repository URL git@github.com:Andrew374e1/ProjectForge-WMS.git.
3. Create or choose a Plesk SSH key.
4. Copy the complete value shown under SSH public key content.
5. In the GitHub repository, open Settings, Deploy keys, and Add deploy key.
6. Use an environment-specific title such as Project Forge WMS - Production Plesk.
7. Paste the public key and leave write access disabled.
8. Return to Plesk and finish creating the repository.

Key security: register only the public key. Never copy, publish, or commit the corresponding private key. Use separate deploy keys for staging and production.

2.2 Configure the Plesk repository

Repository type	Remote repository
Active branch	main
Deployment path	/
Deployment mode	Manual
Post-deploy actions	Disabled

Fetch the repository and perform one controlled manual deployment to install the application and updater foundation. Keep deployment mode manual afterward. Routine releases must be installed through System Update.

2.3 Configure PHP in Plesk

1. In Plesk, open the environment domain.
2. Open PHP Settings.
3. Enable PHP support.
4. Use the tested PHP version, currently 8.5. The application manifest requires PHP 8.3 or newer.
5. Set Run PHP as to FPM application served by nginx.
6. Set short_open_tag to on.
7. Confirm the curl, mysqli, and zip extensions are available.
8. Apply the PHP settings before testing login or System Update.

Required handler: do not use a different PHP handler for this installation. Incorrect handler settings can produce different routing behavior, including POST requests being redirected to extensionless GET requests.

sudo plesk bin domain --show-php-settings ENVIRONMENT_DOMAIN |
  grep -iE 'short_open_tag|open_basedir'

Replace ENVIRONMENT_DOMAIN with the exact staging or production domain. The output must show short_open_tag = on.

2.4 Create the application database configuration

Create the environment-specific application configuration in the APP_ROOT/httpdocs/includes directory. The filename is config.php. This file supplies the database connection used by the website, login, background jobs, integrations, and System Update.

The configuration must define the values expected by the existing WMS bootstrap:

define('DB_HOST', 'DATABASE_HOST');
define('DB_USER', 'DATABASE_USERNAME');
define('DB_PASS', 'DATABASE_PASSWORD');
define('DB_NAME', 'DATABASE_NAME');

• Replace every placeholder with the credentials for that environment.
• Production must use the production database. It must never point to the staging database.
• Staging must use the staging database.
• Never commit this file or include its contents in documentation, tickets, chat, screenshots, or logs.
• Keep the file protected from release replacement and managed-file deletion.
• Recommended file mode is 0640, readable by the website user and its subscription group.

APP_ROOT=/var/www/vhosts/ENVIRONMENT_DOMAIN
SITE_USER=$(stat -c '%U' "$APP_ROOT/httpdocs")
SITE_GROUP=$(stat -c '%G' "$APP_ROOT/httpdocs")
CONFIG_DIR="$APP_ROOT/httpdocs/includes"
DB_CONFIG=$(printf '%s/%s' "$CONFIG_DIR" "config.php")

sudo chown "$SITE_USER:$SITE_GROUP" "$DB_CONFIG"
sudo chmod 0640 "$DB_CONFIG"

Credential verification: confirm the database host and database name before login testing. Do not print or expose the database password.

2.5 Create a GitHub token for System Update

Create a fine-grained personal access token for each environment. This token is separate from the Plesk SSH deploy key: Plesk Git uses SSH for the initial repository deployment, while System Update uses the token to read private GitHub Releases and download their assets.

The example above shows the production token limited to the Project Forge repository, with Contents and required Metadata permissions set to read-only. Click the image to open the full-size version.

1. Sign in to the GitHub account that can read Andrew374e1/ProjectForge-WMS.
2. Open the profile menu, then Settings.
3. Open Developer settings.
4. Open Personal access tokens, then Fine-grained tokens.
5. Click Generate new token.
6. Enter an environment-specific name such as Project Forge WMS - Production Updater.
7. Set an expiration date that follows company credential-rotation policy.
8. Set the resource owner to Andrew374e1.
9. Limit repository access to ProjectForge-WMS only.
10. Under repository permissions, set Contents to Read-only. GitHub supplies required metadata read access automatically.
11. Leave every unrelated permission at its default no-access value.
12. Generate the token and copy it immediately. GitHub displays the complete token only once.
13. Store it directly in the environment's private config/system_update.php file.

Token security: never paste a real token into kbase, tickets, chat, terminal history, screenshots, application logs, or Git. Use separate staging and production tokens so either environment can be revoked independently.

Official reference: Managing personal access tokens on GitHub.

Validate the token without displaying it

read -rsp "GitHub token: " GITHUB_TOKEN
echo

curl --silent --show-error \
  --header "Accept: application/vnd.github+json" \
  --header "Authorization: Bearer $GITHUB_TOKEN" \
  --header "X-GitHub-Api-Version: 2022-11-28" \
  --write-out "HTTP_STATUS=%{http_code}\n" \
  https://api.github.com/repos/Andrew374e1/ProjectForge-WMS

unset GITHUB_TOKEN

A valid token returns repository metadata and HTTP_STATUS=200. A private repository commonly returns 404 when the token is invalid, expired, assigned to the wrong owner, or missing repository access.

2.6 Create the private channel configuration

Create the file outside httpdocs.

Environment	Exact path	Channel
Staging	/var/www/vhosts/staging.wms.thethreelogistics.com/config/system_update.php	staging
Production	/var/www/vhosts/analytics.thethreelogistics.com/config/system_update.php	production

The staging file returns this array:

return [
    'channel' => 'staging',
    'github_token' => 'STAGING_GITHUB_TOKEN',
];

The production file returns this array:

return [
    'channel' => 'production',
    'github_token' => 'PRODUCTION_GITHUB_TOKEN',
];

• Use a fine-grained token limited to Andrew374e1/ProjectForge-WMS with Contents read access.
• Never place the token under httpdocs or commit it to Git.
• Set file mode 0640 and ownership that allows web PHP and the scheduled worker to read it.
• A valid PROJECT_FORGE_UPDATE_CHANNEL environment value takes precedence over the private file.
• The hostname, Git branch, Plesk repository, and manifest do not determine the channel.

Release filtering: staging accepts prereleases and stable releases. Production rejects drafts and prereleases and accepts stable releases only.

2.7 Create private updater storage

APP_ROOT=/var/www/vhosts/ENVIRONMENT_DOMAIN
DOCROOT="$APP_ROOT/httpdocs"
UPDATE_STORAGE="$APP_ROOT/storage/system_updates"
SITE_USER=$(stat -c '%U' "$DOCROOT")
SITE_GROUP=$(stat -c '%G' "$DOCROOT")

sudo install -d -o "$SITE_USER" -g "$SITE_GROUP" -m 0750 \
  "$APP_ROOT/storage" \
  "$UPDATE_STORAGE" \
  "$UPDATE_STORAGE/downloads" \
  "$UPDATE_STORAGE/extracted" \
  "$UPDATE_STORAGE/backups" \
  "$UPDATE_STORAGE/locks" \
  "$UPDATE_STORAGE/logs"

Replace ENVIRONMENT_DOMAIN with the exact staging or production domain. Storage must remain outside httpdocs.

2.8 Configure the scheduled worker

• In Plesk Scheduled Tasks, use task type Run a PHP script.
• Script path: schedulescripts/system_update.php.
• PHP version: 8.5.
• Schedule: every minute.
• Run as the website subscription user.

Do not use Run a command. The Plesk chroot command environment may not contain the required PHP executable.

2.9 Verify the installation

• Confirm the System Update page displays the correct environment channel.
• Confirm PHP runs as an FPM application served by nginx and short_open_tag is on.
• Confirm the application database configuration points to the correct environment database.
• Confirm the private configuration and updater storage resolve outside httpdocs.
• Confirm the website user can write to updater storage.
• Confirm PHP provides curl, mysqli, and zip.
• Run the scheduled task once and confirm it exits normally when no job is queued.
• Keep Plesk Git deployment mode set to manual.

3. One-Time Server Requirements

Requirement	Staging	Production
Channel	staging	production
GitHub token	Fine-grained private-repository token with Contents read access.
PHP	PHP 8.3+; tested with Plesk PHP 8.5; FPM application served by nginx;  short_open_tag = on ;  curl ,  mysqli , and  zip .
Database config	Directory:  APP_ROOT/httpdocs/includes . Filename:  config.php . It must be environment-specific, protected, and excluded from releases.
Private config	APP_ROOT/config/system_update.php , outside  httpdocs , mode  0640 .
Private storage	APP_ROOT/storage/system_updates , outside  httpdocs , writable by website user.
Plesk Git	Manual deployment mode.
Worker	Plesk  Run a PHP script ;  schedulescripts/system_update.php ; PHP 8.5; every minute.

4. Manifest and Version Requirements

• Use semantic versions, for example 1.0.6.
• Increase the numeric build for every release.
• The tag must be v plus the exact manifest version.
• Set release date and administrator-readable release notes.
• Change database_version only when adding migrations.
• Never edit a published release manifest or move an installed tag.

{
  "application": "Project Forge WMS",
  "version": "1.0.6",
  "build": 6,
  "release_date": "2026-07-21",
  "minimum_php": "8.3",
  "minimum_mariadb": "11.8",
  "database_version": "20260717_001",
  "release_notes": [
    "Describe the administrator-visible change.",
    "Describe important operational or security behavior."
  ]
}

5. Local Developer Commands

5.1 Start with a clean branch

cd C:\Development\wms
git status --short
git branch --show-current
git pull --ff-only

Use main. Resolve unrelated changes before release preparation.

5.2 Review edits

git status --short
git diff
git diff -- path\to\specific-file.php

5.3 Validate

C:\xampp\php\php.exe -l path\to\changed-file.php
C:\xampp\php\php.exe httpdocs\modules\system_update\tests\system_update_tests.php

Syntax-check every changed PHP file and require all relevant tests to pass.

5.4 Add, review, commit, and push development changes

git add path\to\changed-file.php path\to\another-file.js
git status --short
git diff --cached
git commit -m "Describe the implemented change"
git push origin main

Use explicit paths. Review staged changes before committing and preserve unrelated work.

6. Prepare and Publish the Release

6.1 Commit the manifest

git diff -- httpdocs/manifest.json
git add httpdocs/manifest.json
git diff --cached
git commit -m "Release v1.0.6"
git push origin main

6.2 Verify before tagging

git status --short
git log -2 --oneline

The worktree must be clean and the release commit must already appear on origin/main.

6.3 Tag the release commit

git tag -a v1.0.6 -m "Project Forge WMS v1.0.6"
git push origin v1.0.6
git show v1.0.6 --no-patch --format=fuller

6.4 Verify GitHub Actions and assets

The release workflow must succeed and create a prerelease with exactly:

project-forge-wms-v1.0.6.zip
project-forge-wms-v1.0.6.sha256

If the workflow fails, fix the workflow or code; do not manually create an incomplete Release.

7. Correcting an Unpublished Bad Tag

Replace a tag only when no valid Release/assets exist and no server consumed it.

git ls-remote --tags origin refs/tags/v1.0.6
git push origin --delete v1.0.6
git tag -d v1.0.6

# Correct and commit first, then recreate:
git tag -a v1.0.6 -m "Project Forge WMS v1.0.6"
git push origin v1.0.6

Published or installed tag: never move it. Publish a new version and build.

8. Staging Installation and Testing

1. Confirm Plesk Git mode is manual; do not deploy the repository.
2. Open staging System Update and click Check for Updates.
3. Verify local/remote version and build, channel staging, tag, requirements, and migrations.
4. For migrations, create and verify an external database backup.
5. Click Update exactly once.
6. The Plesk PHP scheduled task claims the queued job.
7. Wait for status done and phase complete.

APP_ROOT=/var/www/vhosts/staging.wms.thethreelogistics.com

grep -E '"version"|"build"' "$APP_ROOT/httpdocs/manifest.json"
ls -lt "$APP_ROOT/storage/system_updates/logs"
sed -n '1,300p' "$APP_ROOT/storage/system_updates/logs/JOB_ID.log"
ls -l "$APP_ROOT/config/system_update.php"

Required staging tests

• Installed manifest exactly matches the candidate version/build.
• A new update check no longer offers the installed release.
• Login, permissions, navigation, layouts, and target modules render.
• Critical WMS workflows and background jobs succeed.
• Uploads, attachments, private config, and protected paths are unchanged.
• Job log confirms checksum verification and completion.

9. Record Staging Approval

Tag and commit	Exact tag and full commit SHA
Artifact	ZIP filename and SHA-256
Job	Staging job ID and completion time
Database backup	Backup ID/time when migrations exist
Testing	Tester, results, issues, and approval time

10. Promote Without Rebuilding

1. Open the existing tested GitHub Release.
2. Edit it and clear Set as a pre-release.
3. Save without changing the tag or assets.

Immutability gate: tag, commit, ZIP bytes, filename, and SHA-256 must remain identical to staging.

11. Production Deployment

11.1 Readiness

• Production channel is production.
• Updater foundation and private storage are already installed and tested.
• Plesk task is Run a PHP script, PHP 8.5, every minute.
• Plesk Git automatic deployment is disabled.
• Application and database backups are current and recoverable.
• Monitoring, maintenance window, and responsible operators are ready.

11.2 Install and verify

1. Click Check for Updates.
2. Confirm channel, stable tag, version, build, requirements, and checksum identity.
3. Confirm backups and click Update once.
4. Monitor until done/complete.
5. Verify manifest, log, protected paths, health, and business workflows.

APP_ROOT=/var/www/vhosts/production.example.com

grep -E '"version"|"build"' "$APP_ROOT/httpdocs/manifest.json"
ls -lt "$APP_ROOT/storage/system_updates/logs"
sed -n '1,300p' "$APP_ROOT/storage/system_updates/logs/JOB_ID.log"

12. Failure Rules

• Do not repeatedly click Update; inspect the existing job and its log.
• Do not move the tag or replace assets after consumption.
• Correct a failed candidate by publishing a new version/build.
• Before migration, verify automatic file rollback results.
• During/after migration, stop and use the external database recovery plan.
• Preserve logs, inventory, checksum, tag, and commit as incident evidence.

13. Final Checklist

1. Changes reviewed; syntax and tests pass.
2. Manifest version/build/date/notes are correct.
3. Release commit is on origin/main.
4. Tag points to that release commit.
5. GitHub prerelease and both custom assets exist.
6. Staging installs and validates the exact artifact.
7. Release is promoted by metadata only.
8. Production readiness and backup gates pass.
9. Production installs and validates the same immutable artifact.
