-# Bugs in µPaaS
-
-## 1. Potential Race Condition in Log Writing
-
-### Description
-In the deployment service, when a deployment fails, the `failDeployment` function calls `writeLogsToFile` which may be called concurrently with the async log writer's flush operations. This could lead to partial or corrupted log files.
-
-### Location
-`internal/service/deploy/deploy.go:1169` in `failDeployment` function
-
-### Proposed Fix
-1. Add synchronization to ensure only one log write operation occurs at a time
-2. Modify the `deploymentLogWriter` to track completion status and prevent concurrent writes
-3. Add a wait mechanism in `failDeployment` to ensure any ongoing flush operations complete before writing logs to file
-
-```go
-// Add a mutex to deploymentLogWriter
-type deploymentLogWriter struct {
-    // existing fields...
-    mu         sync.Mutex
-    writeMu    sync.Mutex  // Add this for file writing synchronization
-    done       chan struct{}
-    flushed    sync.WaitGroup
-}
-
-// In writeLogsToFile, ensure exclusive access
-func (svc *Service) writeLogsToFile(app *models.App, deployment *models.Deployment) {
-    svc.writeMu.Lock()  // Add this mutex to Service struct
-    defer svc.writeMu.Unlock()
-    // existing code...
-}
-```
-
-## 2. Incomplete Error Handling in Container Operations
-
-### Description
-In the Docker client's `performClone` function, if `createGitContainer` fails, the SSH key file created earlier is not cleaned up, causing a potential security risk.
-
-### Location
-`internal/docker/client.go:597` in `performClone` function
-
-### Proposed Fix
-Add proper cleanup using `defer` immediately after creating the SSH key file:
-
-```go
-// After writing SSH key file (line 578)
-keyFileCreated := false
-err = os.WriteFile(cfg.keyFile, []byte(cfg.sshPrivateKey), sshKeyPermissions)
-if err != nil {
-    return nil, fmt.Errorf("failed to write SSH key: %w", err)
-}
-keyFileCreated = true
-
-defer func() {
-    if keyFileCreated {
-        removeErr := os.Remove(cfg.keyFile)
-        if removeErr != nil {
-            c.log.Error("failed to remove SSH key file", "error", removeErr)
-        }
-    }
-}()
-```
-
-## 3. Missing Context Cancellation Check During Build
-
-### Description
-In the deployment service's `streamBuildOutput` function, long-running Docker build operations may not properly respond to context cancellation, causing deployments to hang even when cancelled.
-
-### Location
-`internal/docker/client.go:542` in `streamBuildOutput` function
-
-### Proposed Fix
-Add context checking in the scanner loop:
-
-```go
-for scanner.Scan() {
-    select {
-    case <-ctx.Done():
-        return ctx.Err()
-    default:
-    }
-    
-    line := scanner.Bytes()
-    // existing code...
-}
-```
-
-## 4. Inconsistent Container Removal in Error Cases
-
-### Description
-When deployment fails during container creation, the already-created container is not removed, leading to orphaned containers that consume resources.
-
-### Location
-`internal/service/deploy/deploy.go:969` in `createAndStartContainer` function
-
-### Proposed Fix
-Add cleanup of created container on start failure:
-
-```go
-containerID, err := svc.docker.CreateContainer(ctx, containerOpts)
-if err != nil {
-    svc.notify.NotifyDeployFailed(ctx, app, deployment, err)
-    svc.failDeployment(ctx, app, deployment, fmt.Errorf("failed to create container: %w", err))
-    return "", fmt.Errorf("failed to create container: %w", err)
-}
-
-// Add cleanup defer for error cases
-defer func() {
-    if err != nil {
-        // If we have a container ID but returning an error, clean it up
-        _ = svc.docker.RemoveContainer(context.Background(), containerID, true)
-    }
-}()
-
-startErr := svc.docker.StartContainer(ctx, containerID)
-if startErr != nil {
-    svc.notify.NotifyDeployFailed(ctx, app, deployment, startErr)
-    svc.failDeployment(ctx, app, deployment, fmt.Errorf("failed to start container: %w", startErr))
-    err = startErr  // Set err so defer cleanup runs
-    return "", fmt.Errorf("failed to start container: %w", startErr)
-}
-```
-
-## 5. Potential Data Race in Active Deployments Tracking
-
-### Description
-The `activeDeploys` sync.Map in the deployment service may have race conditions when multiple concurrent deployments try to access the same app's deployment state.
-
-### Location
-`internal/service/deploy/deploy.go:226` and related functions
-
-### Proposed Fix
-Add proper locking around active deploy operations:
-
-```go
-// Add a mutex for active deploy operations
-type Service struct {
-    // existing fields...
-    activeDeployMu sync.Mutex
-}
-
-// In Deploy function
-func (svc *Service) Deploy(ctx context.Context, app *models.App, webhookEventID *int64, cancelExisting bool) error {
-    svc.activeDeployMu.Lock()
-    if cancelExisting {
-        svc.cancelActiveDeploy(app.ID)
-    }
-    
-    // Try to acquire per-app deployment lock
-    if !svc.tryLockApp(app.ID) {
-        svc.activeDeployMu.Unlock()
-        svc.log.Warn("deployment already in progress", "app", app.Name)
-        return ErrDeploymentInProgress
-    }
-    svc.activeDeployMu.Unlock()
-    
-    defer svc.unlockApp(app.ID)
-    // rest of function...
-}
-```
-
-## 6. Incomplete Error Propagation in Git Clone
-
-### Description
-In the Docker client's `runGitClone` function, if `ContainerLogs` fails, the error is silently ignored, which could hide important debugging information.
-
-### Location
-`internal/docker/client.go:679` in `runGitClone` function
-
-### Proposed Fix
-Handle the ContainerLogs error properly:
-
-```go
-// Always capture logs for the result
-logs, logErr := c.ContainerLogs(ctx, containerID, "100")
-if logErr != nil {
-    c.log.Warn("failed to get git clone logs", "error", logErr)
-    logs = "Failed to retrieve logs: " + logErr.Error()
-}
-```

-# Repository Rules
-
-Last Updated 2026-01-08
-
-These rules MUST be followed at all times, it is very important.
-
-* Never use `git add -A` - add specific changes to a deliberate commit. A
-  commit should contain one change. After each change, make a commit with a
-  good one-line summary.
-
-* NEVER modify the linter config without asking first.
-
-* NEVER modify tests to exclude special cases or otherwise get them to pass
-  without asking first. In almost all cases, the code should be changed,
-  NOT the tests. If you think the test needs to be changed, make your case
-  for that and ask for permission to proceed, then stop. You need explicit
-  user approval to modify existing tests. (You do not need user approval
-  for writing NEW tests.)
-
-* When linting, assume the linter config is CORRECT, and that each item
-  output by the linter is something that legitimately needs fixing in the
-  code.
-
-* When running tests, use `make test`.
-
-* Before commits, run `make check`. This runs `make lint` and `make test`
-  and `make check-fmt`. Any issues discovered MUST be resolved before
-  committing unless explicitly told otherwise.
-
-* When fixing a bug, write a failing test for the bug FIRST. Add
-  appropriate logging to the test to ensure it is written correctly. Commit
-  that. Then go about fixing the bug until the test passes (without
-  modifying the test further). Then commit that.
-
-* When adding a new feature, do the same - implement a test first (TDD). It
-  doesn't have to be super complex. Commit the test, then commit the
-  feature.
-
-* When adding a new feature, use a feature branch. When the feature is
-  completely finished and the code is up to standards (passes `make check`)
-  then and only then can the feature branch be merged into `main` and the
-  branch deleted.
-
-* Write godoc documentation comments for all exported types and functions as
-  you go along.
-
-* ALWAYS be consistent in naming. If you name something one thing in one
-  place, name it the EXACT SAME THING in another place.
-
-* Be descriptive and specific in naming. `wl` is bad;
-  `SourceHostWhitelist` is good. `ConnsPerHost` is bad;
-  `MaxConnectionsPerHost` is good.
-
-* This is not prototype or teaching code - this is designed for production.
-  Any security issues (such as denial of service) or other web
-  vulnerabilities are P1 bugs and must be added to TODO.md at the top.
-
-* As this is production code, no stubbing of implementations unless
-  specifically instructed. We need working implementations.
-
-* Avoid vendoring deps unless specifically instructed to.  NEVER commit
-  the vendor directory, NEVER commit compiled binaries.  If these
-  directories or files exist, add them to .gitignore (and commit the
-  .gitignore) if they are not already in there.  Keep the entire git
-  repository (with history) small - under 20MiB, unless you specifically
-  must commit larger files (e.g. test fixture example media files).  Only
-  OUR source code and immediately supporting files (such as test examples)
-  goes into the repo/history.
