- Record refunds immediately before cancellation to prevent retry issues if cancel fails
- Wrap Stripe API calls in try-catch for refunds and quantity reverts with internal notifications
- Add null check in Team.subscriptionEnded() to prevent NPE when subscription doesn't exist
- Fix control flow bug in StripeProcessJob (add missing break statement)
- Cap dynamic server limit with MAX_SERVER_LIMIT in subscription updates
- Add comprehensive tests for refund failures, event handling, and null safety
Add current_period_end to refund eligibility checks and display next billing
date and billing interval in the subscription overview. Refactor the plan
overview layout to show subscription status more prominently.
- Log warnings instead of silently failing when chmod 0600 fails
- Remove redundant refresh() call before SSH key validation
- Remove storeInFileSystem() call from updatePrivateKey() transaction
- Remove @unlink() of lock file after filesystem store
- Refactor unit tests to use real temp disk and anonymous class stub
instead of reflection-only checks
- Restrict "Add suffix for PR deployments" checkbox to non-service
resources in both shared and service file-storage views
- Replace condition `is_preview_deployments_enabled` with `!$isService`
for PR suffix visibility in storages/show.blade.php
- Fix FileStorage::instantSave() to use authorize + syncData instead
of delegating to submit(), preventing unintended side effects
- Add $this->validate() to Storages/Show::instantSave() before saving
- Add response content schemas to storages API OpenAPI annotations
- Add additionalProperties: false to storage update request schema
- Rewrite PreviewDeploymentBindMountTest with behavioral tests of
addPreviewDeploymentSuffix instead of file-content inspection
Add `is_preview_suffix_enabled` flag to `local_file_volumes` and
`local_persistent_volumes` tables, allowing per-volume control over
whether a `-pr-N` suffix is appended during preview deployments.
Defaults to `true` to preserve existing behavior. Users can disable
it for volumes containing shared config or repository scripts that
should not be isolated per PR.
Bind mount volumes reference files at the repository's original path and
should not receive the -pr-N suffix. Only named Docker volumes require
the suffix for isolation between preview deployments.
Adds PreviewDeploymentBindMountTest to verify the correct behavior.
Fixes#7802
The root cause of sporadic "Permission denied (publickey)" errors was
that validateSshKey() only checked if the key file existed on disk,
never verifying its content matched the database. When keys were rotated
or updated, the stale file persisted and SSH used the wrong key.
Changes:
- validateSshKey() now refreshes key from DB and compares file content
- Server saved event detects private_key_id changes to invalidate mux
- PrivateKey storeInFileSystem() uses file locking to prevent races
- PrivateKey saved event auto-resyncs file on key content changes
- Enforces 0600 permissions on key files
Fixescoollabsio/coolify#7724
Server metadata is now automatically gathered when server validation completes successfully, both in the async job and Livewire component. This ensures server details (OS, CPU count, etc.) are populated immediately after validation passes, improving the user experience without requiring manual metadata fetching.
Tests added to verify gatherServerMetadata is called on successful validation and skipped when validation fails.
The generate_preview_fqdn_compose method now extracts and populates the fqdn field from docker_compose_domains, making it available for webhook notifications. This handles multiple domains across services and gracefully sets fqdn to null when no domains are configured.
When adding --project-directory to custom docker compose start commands,
use the application's host workdir if preserveRepository is true, otherwise
use the container workdir. Add tests for both scenarios and explicit paths.
Add `is_container_label_escape_enabled` boolean field to services API,
allowing users to control whether special characters in container labels
are escaped. Defaults to true (escaping enabled).
When disabled, users can use environment variables within labels.
Includes validation rules and comprehensive test coverage.
- Add -i flag to explicitly specify ssh key path in git ls-remote operations
- Remove static $rules properties in favor of dynamic rules() method
- Fix test syntax error
- Prioritize real private keys (id > 0) first
- Check source second before falling back to zero key
- Remove isDev() check that was restricting zero key behavior in dev
- Remove exception throw, use 'other' as safe fallback
- Expand test coverage to validate all precedence scenarios
Allow passing a custom GIT_SSH_COMMAND to setGitImportSettings() so that git fetch,
submodule update, and lfs pull use the same SSH authentication as the initial clone.
This is required for git sources like GitLab that use custom ports and identity files.
Also remove unnecessary SSH retry event tracking and add test coverage.
Ensure proper type comparison when verifying deployment team ownership.
Adds comprehensive feature tests for the GET /api/v1/deployments/{uuid} endpoint.
Extract shared variable resolution logic into a reusable helper function
`resolveSharedEnvironmentVariables()` and apply it in applicationParser and
serviceParser to ensure patterns like {{environment.VAR}}, {{project.VAR}},
and {{team.VAR}} are properly resolved in the compose environment section.
Without this, unresolved {{...}} strings would take precedence over resolved
values from the .env file (env_file:) in docker-compose configurations.
Add comprehensive test suite verifying that magic (referenced) SERVICE_URL_ and
SERVICE_FQDN_ variables don't overwrite values set by direct template declarations
or updateCompose(). Tests cover the fix for GitHub issue #8912 where generic
SERVICE_URL and SERVICE_FQDN variables remained stale after changing a service
domain in the UI. These tests ensure the transition from updateOrCreate() to
firstOrCreate() in the magic variables section works correctly.
Add ability to gather and display server system information including OS, architecture, kernel version, CPU count, memory, and uptime. Includes:
- New gatherServerMetadata() method to collect system details via remote commands
- New refreshServerMetadata() Livewire action with authorization and error handling
- Server Details UI section showing collected metadata with refresh capability
- Database migration to add server_metadata JSON column
- Comprehensive test suite for metadata collection and persistence

Improvements to credential handling:
- URL-encode GitHub access tokens to handle special characters properly
- Update log sanitization to redact passwords from HTTPS/HTTP URLs
- Extend convertGitUrl() type hints to support GitlabApp sources
Add test coverage and seed data:
- New GitlabSourceCommandsTest with tests for private key and public repo scenarios
- Test for HTTPS basic auth password sanitization in logs
- Seed data for GitLab deploy key and public example applications
- Add `$selectedActions = []` parameter to delete/remove methods in multiple
Livewire components to support optional deletion actions
- Return error message string when password verification fails instead of
silent return
- Return `true` on successful deletion to indicate completion
- Handle selectedActions to set component properties for cascading deletions
(delete_volumes, delete_networks, delete_configurations, docker_cleanup)
- Add test coverage for Danger component delete functionality with password
validation and selected actions handling
- Store proxy configuration in database as primary source for faster access
- Implement automatic timestamped backups when configuration changes
- Add backfill migration logic to recover configs from disk for legacy servers
- Simplify UI by removing loading states (config now readily available)
- Add comprehensive logging for debugging configuration generation and recovery
- Include unit tests for config recovery scenarios
When application->fqdn is null, COOLIFY_FQDN and COOLIFY_URL are set to null.
These null values cause nixpacks to fail parsing the config with
"invalid type: null, expected a string".
Filter out null and empty string values when generating environment variables
for the nixpacks plan JSON. Fixes#6830.
Replace direct shell interpolation of environment values with base64 encoding
to prevent command injection attacks. Environment configuration is now built as
a single string, base64-encoded, then decoded to file atomically.
Also add regex validation to restrict environment field values to safe
characters (alphanumeric, underscore, hyphen, dot) at the application layer.
Fixes GHSA-3xm2-hqg8-4m2p
Add validateGitRef() helper function that uses an allowlist approach to prevent
OS command injection through git commit SHAs, branch names, and tags. Only allows
alphanumeric characters, dots, hyphens, underscores, and slashes.
Changes include:
- Add validateGitRef() helper in bootstrap/helpers/shared.php
- Apply validation in Rollback component when accepting rollback commit
- Add regex validation to git commit SHA fields in Livewire components
- Apply regex validation to API rules for git_commit_sha
- Use escapeshellarg() in git log and git checkout commands
- Add comprehensive unit tests covering injection payloads
Addresses GHSA-mw5w-2vvh-mgf4
Validation operations should require write permissions as they trigger
state-changing actions. Updated middleware for:
- POST /api/v1/cloud-tokens/{uuid}/validate
- GET /api/v1/servers/{uuid}/validate
Added tests to verify read-only tokens cannot access these endpoints.
Previously, the view checked $privateKeyId with ! operator, which
incorrectly treats 0 (localhost key) as falsy. Changed to explicit
is_null() checks to distinguish between null (no key) and 0 (localhost).
Added test coverage for both cases.
Handle non-positive disable counts with `<= 0` so teams at or under the
server limit correctly re-enable force-disabled servers. Add a feature test
suite for ServerLimitCheckJob covering under-limit, at-limit, over-limit,
and no-op behavior.
Centralize min/max server limits in Stripe quantity updates and wire them into
Livewire subscription actions with price preview/update handling.
Also improve host/proxy middleware behavior by trusting loopback hosts when FQDN
is set and auto-enabling secure session cookies for HTTPS requests behind
proxies when session.secure is unset.
Includes feature tests for loopback trust and secure cookie auto-detection.
Introduce a new `UpdateSubscriptionQuantity` Stripe action to:
- preview prorated due-now and next-cycle recurring costs
- update subscription item quantity with proration invoicing
- revert quantity and void invoice when payment is not completed
Wire the flow into the Livewire subscription actions UI with a new adjust-limit modal,
price preview loading, and confirmation-based updates. Also refactor the subscription
management section layout and fix modal confirmation behavior for temporary 2FA bypass.
Add `Subscription::billingInterval()` helper and comprehensive Pest coverage for
quantity updates, preview calculations, failure/revert paths, and billing interval logic.
Enable `HasFactory` on `Environment`, `Project`, `ScheduledTask`, and
`StandaloneDocker`, and add dedicated factories for related models to
stabilize feature/unit tests.
Also bump `visus/cuid2` to `^6.0` and refresh `composer.lock` with the
resulting dependency updates.
Add is_required field to the EnvironmentVariable model's fillable
array to allow mass assignment. Include comprehensive tests to verify
all fillable fields are properly configured for mass assignment.
- Refactor shouldRunNow() to only fire on first run (empty cache) if actually due by cron schedule, preventing spurious executions after cache loss or service restart

Implement dedup key-based cron tracking to make scheduled jobs resilient to queue
delays. Even if a job is delayed by minutes, it will catch the missed cron window
by tracking previousRunDate in cache instead of relying on isDue() alone.
- Add dedupKey parameter to shouldRunNow() in ScheduledJobManager
- When provided, uses getPreviousRunDate() + cache tracking for resilience
- Falls back to isDue() for docker cleanups without dedup key
- Prevents double-dispatch within same cron window
- Optimize ServerConnectionCheckJob dispatch
- Skip SSH checks if Sentinel is healthy (enabled and live)
- Reduces redundant checks when Sentinel heartbeat proves connectivity

- Add comprehensive test suite for scheduling with various delay scenarios and timezones
Reduce unnecessary job queue pressure and improve subscription sync reliability:
- Cache ServerStorageCheckJob dispatch to only trigger on disk percentage changes
- Rate-limit ConnectProxyToNetworksJob to maximum once per 10 minutes
- Add progress callback support to SyncStripeSubscriptionsJob for UI feedback
- Implement bulk fetching of valid Stripe subscription IDs for efficiency
- Detect and report resubscribed users (same email, different customer ID)
- Fix CleanupUnreachableServers query operator (>= 3 instead of = 3)
- Improve empty subId validation in PushServerUpdateJob
- Optimize relationship access by using properties instead of query methods
- Add comprehensive test coverage for all optimizations
Properly escape commit SHA using escapeshellarg() before passing it
to shell commands. Add comprehensive tests for git commit rollback
scenarios including shallow clone, fallback behavior, and HEAD handling.
Add support for command-based health checks in addition to HTTP-based checks:

Set up end-to-end browser testing using Pest Browser Plugin + Playwright.
New v4 test suite uses SQLite :memory: database with pre-generated schema dump
(database/schema/testing-schema.sql) instead of running migrations, enabling
faster test startup.
- Add pestphp/pest-plugin-browser dependency
- Create GenerateTestingSchema command to export PostgreSQL schema to SQLite
- Add .env.testing configuration for isolated test environment
- Implement v4 test directory structure (Feature, Browser, Unit tests)
- Update Pest skill documentation with browser testing patterns, API reference,
debugging techniques, and common pitfalls
- Configure phpunit.xml and tests/Pest.php for v4 suite
- Update package.json and docker-compose.dev.yml for testing dependencies
Prevent double-escaping of COMPOSER_AUTH and other JSON environment variables
by detecting valid JSON objects/arrays in realValue() and skipping quote
escaping entirely. This fixes broken JSON values passed to runtime services
while maintaining proper escaping for non-JSON values.
- Add JSON detection before escaping logic in EnvironmentVariable::realValue()
- JSON objects/arrays pass through unmodified, avoiding quote corruption
- Add comprehensive test coverage for JSON vs non-JSON escaping behavior
Wraps inline chart initialization scripts in IIFEs to create local scope for variables. This prevents "Identifier has already been declared" errors when Livewire's SPA navigation re-executes scripts, allowing smooth navigation between metrics pages without page refresh.

This commit introduces advanced environment variable handling capabilities including:
- Nested environment variable resolution with circular dependency detection
- Extraction of hardcoded environment variables from docker-compose.yml
- New ShowHardcoded Livewire component for displaying detected variables
- Enhanced UI for better environment variable management
The changes improve the user experience by automatically detecting and displaying
environment variables that are hardcoded in docker-compose files, allowing users
to override them if needed. The nested variable resolution ensures complex variable
dependencies are properly handled.

This commit fixes two UX issues with environment variable bulk updates:
1. Comment Preservation (High Priority Bug):
- When bulk updating environment variables via Developer view, existing
manually-entered comments are now preserved when no inline comment is provided
- Only overwrites existing comments when an inline comment (#comment) is explicitly
provided in the pasted content
- Previously: pasting "KEY=value" would erase existing comment to null
- Now: pasting "KEY=value" preserves existing comment, "KEY=value #new" overwrites it
2. Save Notification (UX Improvement):
- "Save all Environment variables" button now always shows success notification
- Previously: only showed notification when changes were detected
- Now: provides feedback even when no changes were made
- Consistent with other save operations in the codebase
Changes:
- Modified updateOrCreateVariables() to only update comment field when inline comment
is provided (null check prevents overwriting existing comments)
- Modified handleBulkSubmit() to always dispatch success notification unless error occurred
- Added comprehensive test coverage for bulk update comment preservation scenarios
Tests:
- Added 4 new feature tests covering comment preservation edge cases
- All 22 existing unit tests for parseEnvFormatToArray pass
- Code formatted with Pint

Replace permissive $guarded = [] with explicit $fillable array for better security and clarity. The fillable array includes all 13 fields that are legitimately mass-assignable:
- Core: key, value, comment
- Polymorphic relationship: resourceable_type, resourceable_id
- Boolean flags: is_preview, is_multiline, is_literal, is_runtime, is_buildtime, is_shown_once, is_shared
- Metadata: version, order
Also adds comprehensive test suite (EnvironmentVariableMassAssignmentTest) with 12 test cases covering:
- Mass assignment of all fillable fields
- Comment field edge cases (null, empty, long text)
- Value encryption verification
- Key mutation (trim and space replacement)
- Protection of auto-managed fields (id, uuid, timestamps)
- Update method compatibility
