internal/repositories/errors.go (1)

5-5: 🛠️ Refactor suggestion

Consider improving the error message and using custom error types.

While the current implementation is functional, there are a couple of suggestions for improvement:

1. The error message "not exists" is grammatically incorrect. Consider changing it to "does not exist" or "not found" for better clarity.

2. For more detailed error handling, you might want to use custom error types. This can provide more context and make error handling more robust.

Here's an example of how you could implement this:

type NotExistsError struct {
    Entity string
}

func (e *NotExistsError) Error() string {
    return fmt.Sprintf("%s does not exist", e.Entity)
}

var NewNotExistsError = func(entity string) error {
    return &NotExistsError{Entity: entity}
}

This approach allows you to specify which entity doesn't exist, providing more context to the error.

4-4: ⚠️ Potential issue

Add rollback logic to the Down migration

The "Down" migration is currently empty. It's a best practice to include rollback logic to revert the changes if needed.

Consider adding the reverse operation to the "Down" migration:

-- +goose Down
ALTER TABLE public.t_account ALTER COLUMN difference TYPE your_original_type USING difference::your_original_type;

Replace your_original_type with the column's previous data type.

internal/databse/migrations/sql/20240923185003_delete_foreign_key_from_t_account_and_add_index.sql (2)

6-6: 🛠️ Refactor suggestion

Consider adding reverse operations to the Down section.

The Down section of this migration is currently empty. It's generally a good practice to provide reverse operations for each migration to allow for easy rollback if needed.

Consider adding the following operations to the Down section:

-- +goose Down
ALTER TABLE public.t_account
ADD CONSTRAINT t_account_t_order_number_fk FOREIGN KEY (order_number) REFERENCES [referenced_table](id);

DROP INDEX IF EXISTS t_account_order_number_index;

Note: Replace [referenced_table] with the actual table name that was originally referenced by the foreign key. You may need to check the original schema or previous migrations to get this information.

---

3-4: 💡 Codebase verification

Potential Data Integrity Issue Detected

Dropping the foreign key constraint t_account_t_order_number_fk removes the referential integrity between the t_account and t_order tables. Notably, the internal/repositories/ordersql.go file performs a join between these tables, which could lead to data inconsistencies if not properly managed at the application level.

• Action Items:
  • Review and update the application logic in ordersql.go to handle the absence of the foreign key constraint.
  • Implement necessary validations or checks to maintain data integrity.
  • Ensure there are no other dependencies on this foreign key within the codebase.

Analysis chain

Please clarify the reason for dropping the foreign key constraint.

Dropping the foreign key constraint t_account_t_order_number_fk removes the referential integrity between the t_account table and (presumably) an order table. This could potentially lead to data inconsistencies if not managed carefully at the application level.

Could you please provide more context on why this constraint is being removed? Additionally, run the following script to check for any existing foreign key relationships and their usage:

This will help us understand the impact of removing this constraint and ensure that data integrity is maintained through other means if necessary.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for foreign key relationships and their usage

# Test 1: Look for other foreign keys in the t_account table
rg --type sql -i 'alter table.*t_account.*add constraint.*foreign key'

# Test 2: Search for join operations between t_account and other tables
rg --type go -i 'join.*t_account' || rg --type go -i 't_account.*join'

# Test 3: Look for any references to the dropped foreign key in the codebase
rg -i 't_account_t_order_number_fk'

.gitignore (1)

24-26: 💡 Codebase verification

Remove Unnecessary Ignore Rule for gophermarttest

The gophermarttest directory does not exist or is referenced anywhere in the project. Consider removing this entry from the .gitignore file to keep it clean and maintainable.

Analysis chain

LGTM! Consider the scope of ignoring the test directory.

The additions to the .gitignore file are appropriate and follow good practices:

1. The empty line improves readability by separating different sections.
2. The comment clearly indicates the purpose of the following entries.
3. Ignoring the gophermarttest directory prevents test-related files from being tracked in version control.

However, it's worth considering if the gophermarttest directory should be ignored globally or if it's project-specific. If it's project-specific, it might be better to add it to a local .gitignore file instead. Let's verify if this directory is used across the project:

This will help determine if the ignore rule is appropriate at this level.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for references to gophermarttest directory in the project

# Test: Search for references to gophermarttest
echo "Searching for references to gophermarttest:"
rg --type go --type yaml --type json 'gophermarttest'

# Test: Check if the directory exists
echo "Checking if gophermarttest directory exists:"
fd -t d 'gophermarttest'

internal/payloads/register.go (2)

3-7: 🛠️ Refactor suggestion

Translate the comment to English and consider separating authentication concerns.

1. The comment above the Register struct is in Russian. For better maintainability and accessibility, consider translating it to English:

-// Register пэйлоад для регистрации пользователя, в данный момент и для авторизации)
+// Register payload for user registration (currently also used for authorization)

2. The struct is currently used for both registration and authorization. It's generally a good practice to separate these concerns:

Consider creating separate structs for registration and authorization:

type Register struct {
    Login    string `json:"login" valid:"required,type(string),minstringlength(3)"`
    Password string `json:"password" valid:"required,type(string),minstringlength(6)"`
    // Add any additional fields specific to registration
}

type Login struct {
    Login    string `json:"login" valid:"required,type(string),minstringlength(3)"`
    Password string `json:"password" valid:"required,type(string),minstringlength(6)"`
}

This separation allows for easier maintenance and potential future modifications specific to each use case.

---

9-12: 🛠️ Refactor suggestion

Translate the comment to English and consider adding validation.

1. The comment above the Authorization struct is in Russian. For better maintainability and accessibility, consider translating it to English:

-// Authorization ответ с токеном авторизации
+// Authorization response containing the authorization token

2. Consider adding validation for the Token field:

You might want to add validation to ensure the token is not empty:

type Authorization struct {
    Token string `json:"token" valid:"required,type(string)"`
}

This would help prevent issues with empty tokens being sent or received.

internal/models/OderStatus.go (2)

1-14: ⚠️ Potential issue

Correct the file name to match the struct name.

The file name contains a typo: "Oder" instead of "Order". This should be corrected to maintain consistency and improve code readability.

Please rename the file from OderStatus.go to OrderStatus.go.

---

3-7: ⚠️ Potential issue

Fix typo in struct name and translate comment to English.

The struct definition looks good overall, but there are a couple of improvements to make:

1. The struct name contains a typo: "Oder" should be "Order".
2. The comment is in Russian. Consider translating it to English for better accessibility.

Please apply the following changes:

-// OderStatus статус заказа
-type OderStatus struct {
+// OrderStatus represents the status of an order
+type OrderStatus struct {
 	Code        string `db:"code"`
 	Description string `db:"description"`
 }

The use of db tags is appropriate if you're using this struct with a database ORM.

Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

// OrderStatus represents the status of an order
type OrderStatus struct {
	Code        string `db:"code"`
	Description string `db:"description"`
}

deployments/docker/go/Dockerfile (2)

1-16: 🛠️ Refactor suggestion

Consider implementing a multi-stage build for further optimization.

Overall, this Dockerfile is well-structured and follows many Docker best practices. However, to further optimize the final image size and improve security, consider implementing a multi-stage build.

Here's an example of how you could restructure your Dockerfile as a multi-stage build:

# Build stage
FROM golang:1.22.0-alpine3.19 AS builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download -x
COPY . .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags="-w -s" -o main /app/cmd/gophermart/main.go

# Final stage
FROM alpine:3.19
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /app/main .
ARG PORT=8080
EXPOSE ${PORT}
CMD ["/bin/sh", "-c", "./main"]

This multi-stage build separates the build environment from the runtime environment, resulting in a significantly smaller final image and improved security by not including build tools in the runtime image.

---

11-12: 🛠️ Refactor suggestion

Consider adding optimization flags to the build command.

The build command is correct, but you can optimize the resulting binary by adding some flags.

Consider updating the build command with optimization flags:

-RUN go build -o /app/cmd/gophermart/main /app/cmd/gophermart/main.go
+RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags="-w -s" -o /app/cmd/gophermart/main /app/cmd/gophermart/main.go

These changes will:

• Disable CGO for a statically-linked binary
• Ensure we're building for Linux
• Strip debugging information to reduce binary size

Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

# Build the Go app
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -ldflags="-w -s" -o /app/cmd/gophermart/main /app/cmd/gophermart/main.go

internal/databse/migrations/sql/20240923184506_create_user_table.sql (2)

2-11: 🛠️ Refactor suggestion

Consider the following suggestions for the table structure:

1. The table name t_user uses a prefix 't_'. This naming convention might not be standard in all organizations. Consider if this aligns with your project's naming conventions.

2. The password_hash column stores sensitive information. Ensure that proper security measures are in place in the application layer to hash passwords before storing them.

3. The updated_at column has a default value set to the current timestamp, but it's not clear how it will be automatically updated when a row is modified. Consider adding a trigger to update this column or ensure that your application logic handles this update.

To address point 3, you might want to add a trigger to automatically update the updated_at column. Here's an example of how you could do this:

CREATE OR REPLACE FUNCTION update_modified_column()
RETURNS TRIGGER AS $$
BEGIN
    NEW.updated_at = now();
    RETURN NEW;
END;
$$ language 'plpgsql';

CREATE TRIGGER update_user_modtime
    BEFORE UPDATE ON public.t_user
    FOR EACH ROW
    EXECUTE FUNCTION update_modified_column();

This trigger will automatically update the updated_at column whenever a row is updated.

---

17-17: ⚠️ Potential issue

Add a Down migration for reversibility.

The Down migration section is currently empty. Adding a Down migration is important for reversibility and can be crucial during development or when rolling back changes in production.

Consider adding a Down migration to drop the table:

-- +goose Down
DROP TABLE IF EXISTS public.t_user;

This will allow you to easily revert the changes made by this migration if needed.

.github/workflows/statictest.yml (2)

13-13: 🛠️ Refactor suggestion

Suggestion: Add caching for Go modules.

To improve the workflow's performance, consider adding a step to cache Go modules. This can significantly speed up subsequent runs.

Add the following step after the checkout step:

      - uses: actions/cache@v3
        with:
          path: |
            ~/.cache/go-build
            ~/go/pkg/mod
          key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }}
          restore-keys: |
            ${{ runner.os }}-go-

---

13-13: 🛠️ Refactor suggestion

Suggestion: Run go mod tidy before static tests.

To ensure dependency consistency, it's a good practice to run go mod tidy before running the static tests.

Add the following step before the "Run statictest" step:

      - name: Tidy Go modules
        run: go mod tidy

docker-compose.yml (4)

1-33: 🛠️ Refactor suggestion

Overall structure is good, but consider additional improvements

The Docker Compose file provides a solid foundation for a multi-container application with a PostgreSQL database and a Go service. The basic structure and dependencies are well-defined. However, there are a few additional suggestions to enhance the configuration:

1. Consider adding healthchecks for both services to ensure they're fully operational before being considered "ready".
2. You might want to add a volume for the Go service to enable hot-reloading during development.
3. Consider using a .env file for environment variables to keep sensitive information out of the compose file.

Here's an example of how you could implement these suggestions:

version: "3.8"

services:
  db:
    # ... (previous configuration) ...
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5

  go:
    # ... (previous configuration) ...
    volumes:
      - ./:/app  # Adjust the path as needed
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8645/health"]
      interval: 5s
      timeout: 5s
      retries: 5

volumes:
  postgres_data:

# Add this at the end of the file
# env_file:
#   - .env

Remember to create a .env file in the same directory as your docker-compose.yml with the necessary environment variables:

DB_PASSWORD=your_secure_password
# Add other environment variables as needed

These changes will improve the robustness and security of your Docker Compose setup.

---

1-1: ⚠️ Potential issue

Update Docker Compose version to a valid specification

The current version "0.1" is not a standard Docker Compose version. This may lead to unexpected behavior or errors when running the compose file.

Consider updating to a valid and recent version, such as "3.8":

-version: "0.1"
+version: "3.8"

Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

version: "3.8"

---

5-20: ⚠️ Potential issue

Enhance database service security and persistence

The db service configuration is generally good, but there are two areas for improvement:

1. Security: The database password is hardcoded in the compose file. This is a security risk, especially if the file is committed to version control.
2. Data Persistence: There's no volume specified for the PostgreSQL data, which means data will be lost when the container is removed.

Consider making the following improvements:

1. Use environment variables or Docker secrets for sensitive information:

 environment:
   POSTGRES_DB: gofemart
-  POSTGRES_PASSWORD: example
+  POSTGRES_PASSWORD: ${DB_PASSWORD}

2. Add a named volume for data persistence:

 services:
   db:
     image: postgres
     restart: always
     shm_size: 128mb
+    volumes:
+      - postgres_data:/var/lib/postgresql/data
     environment:
       POSTGRES_DB: gofemart
       POSTGRES_PASSWORD: ${DB_PASSWORD}
     ports:
       - "5432:5432"

+volumes:
+  postgres_data:

Remember to set the DB_PASSWORD environment variable when running docker-compose up.

Committable suggestion was skipped due to low confidence.

22-32: 💡 Codebase verification

⚠️ Potential issue

Address hardcoded password in DATABASE_URI

The go service configuration contains a hardcoded password in the DATABASE_URI environment variable, which is a security risk. To enhance security, consider externalizing sensitive information:

1. Use environment variables for sensitive information:

    environment:
   -  - DATABASE_URI=postgresql://postgres:example@db/gofemart
   +  - DATABASE_URI=postgresql://postgres:${DB_PASSWORD}@db/gofemart

2. Implement secrets management:

   • Utilize tools like Docker Secrets, Kubernetes Secrets, or dedicated secrets management services to securely handle sensitive data.

3. Update your setup to provide the DB_PASSWORD securely:

   • Ensure that the DB_PASSWORD environment variable is set through a secure method, such as a .env file excluded from version control or a secrets manager.

By addressing the hardcoded password, you will significantly improve the security posture of your application.

Analysis chain

Improve security and verify port configuration for the Go service

The go service configuration is generally good, but there are two areas that need attention:

1. Security: The database connection string in the DATABASE_URI environment variable contains a hardcoded password. This is a security risk.
2. Port Configuration: There's a mismatch between the internal port specified here (8080) and the one mentioned in the AI summary (8645).

Consider making the following improvements:

1. Use environment variables for sensitive information in the database URI:

 environment:
-  - DATABASE_URI=postgresql://postgres:example@db/gofemart
+  - DATABASE_URI=postgresql://postgres:${DB_PASSWORD}@db/gofemart

2. Verify the correct internal port for the Go application:

 ports:
-  - "8645:8080"
+  - "8645:8645"  # If 8645 is the correct internal port

Ensure that the internal port matches the port your Go application is configured to listen on.

To verify the correct port configuration, please run the following command:

This will help ensure consistency between the Docker configuration and the Go application code.

.github/workflows/migrations.yml (4)

3-9: ⚠️ Potential issue

Enable workflow triggers

The "on" section is currently commented out, which means this workflow won't be triggered automatically. This is unusual for a production workflow and may have been done for testing purposes.

Consider uncommenting and configuring the "on" section to enable automatic triggering of the workflow. For example:

on:
  pull_request:
  push:
    branches:
      - master
      - main

This configuration will run the workflow on pull requests and pushes to the master and main branches.

---

30-30: 🛠️ Refactor suggestion

Enhance migration step with error handling and logging

The current migration step runs goose up without any error handling or output logging. This could make it difficult to diagnose issues if the migration fails.

Consider enhancing the migration step with error handling and logging:

- name: Run database migrations
  run: |
    set -e
    echo "Starting database migrations..."
    goose up
    if [ $? -eq 0 ]; then
      echo "Migrations completed successfully"
    else
      echo "Migration failed"
      exit 1
    fi

This change will:

1. Set the shell to exit immediately if any command fails (set -e).
2. Log the start and completion of migrations.
3. Check the exit status of the goose up command and log an error message if it fails.
4. Fail the workflow if the migration fails, ensuring that the issue is immediately visible.

26-26: 🛠️ Refactor suggestion

Consider updating actions/checkout to v4

The workflow is currently using actions/checkout@v3. There's a newer version available that may include improvements and bug fixes.

Consider updating to the latest version:

- uses: actions/checkout@v3
+ uses: actions/checkout@v4

This change ensures you're using the most up-to-date version of the action, which may include performance improvements and bug fixes.

Consider optimizing the Luhn algorithm implementation.

While the current implementation is correct, it can be optimized for better performance and readability. Here are some suggestions:

1. Use bytes.Runes() instead of []rune() for more efficient string-to-rune conversion.
2. Iterate forward instead of backward to simplify the logic.
3. Use number[i] - '0' instead of strconv.Atoi() for faster digit conversion.
4. Combine the doubling and "subtract 9 if > 9" steps into a single operation.

Here's an optimized version of the function:

import (
	"errors"
	"unicode"
)

func Check(number string) (bool, error) {
	if number == "" {
		return false, ErrorIncorrectNumber
	}

	var sum int
	parity := len(number) % 2

	for i, ch := range number {
		if !unicode.IsDigit(ch) {
			return false, ErrorIncorrectNumber
		}

		digit := int(ch - '0')
		if i%2 == parity {
			digit *= 2
			if digit > 9 {
				digit -= 9
			}
		}
		sum += digit
	}

	return sum%10 == 0, nil
}

This version is more efficient and easier to read while maintaining the same functionality.

24-24: ⚠️ Potential issue

Add a "Down" migration to drop the table.

The "Down" migration section is currently empty. To ensure reversibility of the migration, it's important to include a "Down" migration that drops the table.

Add the following SQL statement to the "Down" migration:

-- +goose Down
DROP TABLE IF EXISTS t_account;

This will allow for easy reversal of the migration if needed.

Consider parameterizing the host in Swagger annotations.

The host is currently hardcoded to localhost:8080 in the Swagger annotations. This might not be suitable for different environments (e.g., staging, production).

Consider parameterizing the host or using a placeholder that can be replaced during the build or deployment process. For example:

// @host ${API_HOST}

Then, you can replace ${API_HOST} with the actual host during the build or documentation generation process.

30-35: ⚠️ Potential issue

Consider masking sensitive information in logs.

While logging the configuration is helpful for debugging, it might expose sensitive information, especially the databaseDSN which likely contains credentials.

Consider masking sensitive information in logs. For example:

logger.Log.Infow("Running server with configuration",
    "address", cnf.Address,
    "logLevel", cnf.LogLevel,
    "databaseDSN", "********", // Mask the actual DSN
    "accrualSystemAddress", cnf.AccrualSystemAddress,
)

Alternatively, implement a custom logging function that automatically masks known sensitive fields.

---

24-27: 🛠️ Refactor suggestion

Consider using dependency injection for the logger.

The current implementation uses a global logger (logger.Log), which might make testing and dependency injection more difficult.

Consider creating the logger in the main function and passing it to other components that need it. This approach would make the code more modular and easier to test. For example:

log, err := logger.New(cnf.LogLevel)
if err != nil {
    log.Fatal(err)
}

// Use log instead of logger.Log in the rest of the function

// Pass the logger to the application
if err = application.New(cnf, log); err != nil {
    log.Error(err)
}

This change would require updating the application.New function to accept a logger parameter.

1-39: 🛠️ Refactor suggestion

Enhance overall file structure and consistency

The file demonstrates good practices with consistent use of logging and thread-safety mechanisms. However, consider the following improvements for better clarity and maintainability:

1. Add package-level documentation to explain the purpose of the ordercheck package.
2. Consider adding a brief comment or documentation about the Pool struct and WorkedOrder type, even if they're defined elsewhere, to provide context.
3. Standardize all comments to English for consistency.
4. Implement consistent error handling across all methods.

Here's a suggested structure for the file:

// Package ordercheck provides functionality for managing and checking the status of orders.
package ordercheck

import (
	"fmt"
	"gofemart/internal/logger"
)

// Pool represents a collection of orders that can be marked as "in work".
// The actual implementation is defined elsewhere in the package.
type Pool struct {
	// ...
}

// WorkedOrder represents an order that can be marked as "in work".
// The actual implementation is defined elsewhere in the package.
type WorkedOrder struct {
	// ...
}

// MarkOrderInWork attempts to mark an order as "in work".
// It returns the WorkedOrder and true if successful, or nil and false if the order
// is already in work or doesn't exist. An error is returned to distinguish between cases.
func (p *Pool) MarkOrderInWork(number string) (*WorkedOrder, bool, error) {
	// ... (implementation as suggested in previous comment)
}

// MarkOrderNotInWork removes the "in work" flag from an order.
// It returns true if the order was found and updated, false otherwise.
func (p *Pool) MarkOrderNotInWork(number string) bool {
	// ... (implementation as suggested in previous comment)
}

// IsOrderInWork checks if an order is currently marked as "in work".
// It returns true if the order is in work, false if it's not in work or doesn't exist.
func (p *Pool) IsOrderInWork(number string) bool {
	// ... (implementation as suggested in previous comment)
}

This structure provides better context and consistency throughout the file.

20-28: 🛠️ Refactor suggestion

Enhance method naming, documentation, and error handling

The implementation is correct and thread-safe, but consider the following improvements:

1. Rename the method to a more descriptive name, such as MarkOrderNotInWork or FinishWorkOnOrder.
2. Update the comment to English for consistency and wider understanding.
3. Consider returning a boolean to indicate whether the operation was successful.

Here's a suggested refactor:

- // removeFromWork снимаем флаг взятия в работу
- func (p *Pool) removeFromWork(number string) {
+ // MarkOrderNotInWork removes the "in work" flag from an order.
+ // It returns true if the order was found and updated, false otherwise.
+ func (p *Pool) MarkOrderNotInWork(number string) bool {
 	logger.Log.Infow("Remove from work", "number", number)
 	p.mutex.Lock()
 	defer p.mutex.Unlock()
 	if order, ok := p.orderMap[number]; ok {
 		order.inWork = false
+		return true
 	}
+	return false
 }

This refactor improves the method's name, documentation, and adds a return value to indicate success or failure, making it more informative and easier to use.

Improve method naming, documentation, and error handling

While the implementation is correct and thread-safe, consider the following improvements:

1. Rename the method to a more idiomatic Go name, such as MarkOrderInWork or StartWorkOnOrder.
2. Update the comment to English for consistency and wider understanding.
3. Consider returning an error to distinguish between "order not found" and "order already in work" cases.

Here's a suggested refactor:

Improve method naming, documentation, and consider return value semantics

The implementation is correct and uses an appropriate read lock for better concurrency. Consider the following improvements:

1. Rename the method to a more descriptive name, such as IsOrderInWork.
2. Update the comment to English for consistency and wider understanding.
3. Consider distinguishing between "order not found" and "order not in work" cases.

Here's a suggested refactor:

 	}
 	return false
 }

This refactor improves the method's name and documentation. If distinguishing between "not found" and "not in work" is important for your use case, consider changing the return type to (bool, error) to provide more detailed information.

internal/luna/luna_test.go (1)

53-67: 🛠️ Refactor suggestion

LGTM: Well-implemented test execution with a minor suggestion.

The test execution logic is well-implemented:

• Using subtests with t.Run() is a good practice for better organization and reporting.
• The error handling logic correctly distinguishes between cases expecting no error and cases expecting an error.
• The use of errors.Is() for error comparison is appropriate.

However, the error message for non-error cases could be improved for clarity:

Consider updating the error message in the non-error case for better debugging:

 if tc.err == nil {
 	if got != tc.want {
-		t.Errorf("Check(%q) = %v; want %v", tc.input, got, tc.want)
+		t.Errorf("Check(%q) = %v, <nil>; want %v, <nil>", tc.input, got, tc.want)
 	}
 } else {
 	if err == nil || !errors.Is(err, tc.err) {
 		t.Errorf("Check(%q) = %v, %v; want %v, %v", tc.input, got, err, tc.want, tc.err)
 	}
 }

This change makes the error message format consistent between error and non-error cases, which can help in debugging.

10-27: 💡 Codebase verification

Issues Found During Verification

The following items are missing or incorrectly defined in the codebase:

1. ErrorPoolClosed error variable is not defined in internal/ordercheck.
2. WorkedOrder struct is not defined in internal/ordercheck.
3. The field inChanel in the Pool struct is misspelled; it should be inChannel.

Analysis chain

Consider adding nil check and improving variable naming.

The Push method looks good overall, but there are a few suggestions for improvement:

1. Add a nil check for the order parameter before accessing its properties.
2. Improve variable naming: lenChanel -> lenChannel, capChanel -> capChannel.
3. Consider using a constant for the log message strings to improve maintainability.

Here's a suggested improvement:

 func (p *Pool) Push(order *models.Order) (bool, error) {
+	if order == nil {
+		return false, errors.New("order cannot be nil")
+	}
 	logger.Log.Infow("Push order to pool", "order", order.Number)
 	if p.closeFlag.Load() {
 		return false, ErrorPoolClosed
 	}
 	p.mutex.Lock()
 	defer p.mutex.Unlock()
-	lenChanel := len(p.inChanel)
-	capChanel := cap(p.inChanel)
+	lenChannel := len(p.inChannel)
+	capChannel := cap(p.inChannel)
-	if lenChanel < capChanel {
-		logger.Log.Infow("Push order to queue", "order", order.Number, "len", lenChanel, "cap", capChanel)
+	if lenChannel < capChannel {
+		logger.Log.Infow("Push order to queue", "order", order.Number, "len", lenChannel, "cap", capChannel)
 		p.orderMap[order.Number] = &WorkedOrder{model: order}
-		p.inChanel <- order.Number
+		p.inChannel <- order.Number
 		return true, nil
 	}
-	logger.Log.Infow("Order not pushed to queue", "order", order.Number, "len", lenChanel, "cap", capChanel)
+	logger.Log.Infow("Order not pushed to queue", "order", order.Number, "len", lenChannel, "cap", capChannel)
 	return false, nil
 }

Also, please ensure that the following are defined in the package:

1. ErrorPoolClosed error variable
2. WorkedOrder struct
3. Pool struct with its fields (closeFlag, mutex, inChannel, orderMap)

Run the following script to verify:

Improve GeneratePasswordHash method and translate comment.

The method implements secure password hashing using HMAC-SHA256, which is a good practice. However, there are some areas for improvement:

1. Consider returning the generated hash instead of modifying the struct directly. This promotes immutability and makes the function easier to test.
2. The error messages are in English, which is inconsistent with the Russian comment. Stick to one language for consistency.

Here's a suggested refactoring:

// GeneratePasswordHash creates a hash of the user's password
func (u *User) GeneratePasswordHash(hashKey string) (string, error) {
	if u.Password == "" {
		return "", errors.New("password is empty")
	}
	if hashKey == "" {
		return "", errors.New("hash key is empty")
	}
	hasher := hmac.New(sha256.New, []byte(hashKey))
	hasher.Write([]byte(u.Password))
	return hex.EncodeToString(hasher.Sum(nil)), nil
}

Usage:

hash, err := user.GeneratePasswordHash(hashKey)
if err != nil {
    // handle error
}
user.PasswordHash = hash

This approach allows for more flexibility and easier testing of the hash generation logic.

37-49: 🛠️ Refactor suggestion

Improve CheckPasswordHash method and translate comment.

The method correctly uses hmac.Equal for constant-time comparison, which is a good security practice. However, there are some areas for improvement:

1. The method name might be slightly misleading. Consider renaming it to VerifyPasswordHash or ComparePasswordHash for clarity.
2. The error messages are missing, which could make debugging more difficult.
3. The comment is in Russian, which should be translated for consistency.

Here's a suggested refactoring:

// VerifyPasswordHash checks if the provided password hash matches the stored hash
func (u *User) VerifyPasswordHash(providedHash string) (bool, error) {
	decodedProvided, err := hex.DecodeString(providedHash)
	if err != nil {
		return false, fmt.Errorf("failed to decode provided hash: %w", err)
	}
	decodedStored, err := hex.DecodeString(u.PasswordHash)
	if err != nil {
		return false, fmt.Errorf("failed to decode stored hash: %w", err)
	}

	return hmac.Equal(decodedProvided, decodedStored), nil
}

This refactoring improves error messages and renames the method for clarity. Remember to add the fmt package to your imports if you implement these changes.

internal/ordercheck/pushers_test.go (2)

18-46: ⚠️ Potential issue

Incomplete test case for push_to_full_pool.

The test case for pushing to a full pool (lines 29-36) doesn't specify an expected result (want) or error (wantErr). This may lead to an inconclusive test.

Consider updating the test case to include expected outcomes:

{
    name: "push_to_full_pool",
    setup: func(p *Pool) {
        p.inChanel = make(chan string)
    },
    order: &models.Order{
        Number: "1",
    },
    want: false,
    wantErr: nil, // or a specific error if expected
},

Also, consider adding more test cases to cover edge cases or different order numbers.

---

1-73: 🛠️ Refactor suggestion

Consider adding more comprehensive test cases.

While the current tests cover the basic scenarios, consider adding the following to improve test coverage:

1. Test concurrent access to the Pool to ensure thread-safety.
2. Test pushing multiple orders to verify correct behavior with multiple items.
3. Test pushing orders with different number formats to ensure proper handling.

Example for a concurrent test case:

{
    name: "concurrent_push",
    setup: func(p *Pool) {
        p.inChanel = make(chan string, 100)
    },
    order: &models.Order{Number: "1"},
    want: true,
    testFunc: func(t *testing.T, p *Pool) {
        var wg sync.WaitGroup
        for i := 0; i < 10; i++ {
            wg.Add(1)
            go func(i int) {
                defer wg.Done()
                order := &models.Order{Number: fmt.Sprintf("%d", i)}
                _, err := p.Push(order)
                if err != nil {
                    t.Errorf("Concurrent push failed: %v", err)
                }
            }(i)
        }
        wg.Wait()
        if len(p.inChanel) != 10 {
            t.Errorf("Expected 10 orders in channel, got %d", len(p.inChanel))
        }
    },
}

This will help ensure the Pool behaves correctly under concurrent use.

internal/databse/pool.go (2)

18-34: ⚠️ Potential issue

Reconsider handling of empty DSN

The function returns a non-nil *sqlx.DB even when the DSN is empty. This could lead to unexpected behavior or errors later in the application.

Consider returning an error when the DSN is empty, similar to how it's handled in the NewDB function:

if dsn == "" {
    return nil, ErrorEmptyDSN
}

This ensures that an empty DSN is treated as an error condition consistently throughout the package.

Improve error handling and use test logger.

While deferring the body close is good practice, there are a couple of improvements we can make:

57-71: ⚠️ Potential issue

Consider improving the DeleteMutex method for better error handling and mutex management.

While the DeleteMutex method is generally well-implemented and thread-safe, there are a couple of points that could be improved:

1. The mutex is not unlocked after a successful TryLock. This could lead to the mutex remaining locked indefinitely.
2. The error handling could be more specific to differentiate between different scenarios.

Consider applying the following changes:

func (um *UserMutex) DeleteMutex(userID int64) error {
	logger.Log.Debugf("Delete mutex userID: %d", userID)
	um.mutex.Lock()
	defer um.mutex.Unlock()
	mutex, ok := um.usersMap[userID]
	if !ok {
-		return nil
+		return errors.New("mutex not found")
	}
	if mutex.TryLock() {
+		mutex.Unlock() // Unlock the mutex after successful TryLock
		delete(um.usersMap, userID)
		return nil
	}
-	return ErrorUserMutexInUse
+	return fmt.Errorf("failed to delete mutex for user %d: %w", userID, ErrorUserMutexInUse)
}

These changes will:

1. Ensure the mutex is properly unlocked after a successful TryLock.
2. Provide more specific error messages for different scenarios.
3. Include the userID in the error message when the mutex is in use, which can be helpful for debugging.

Don't forget to add "fmt" to the import list if it's not already there.

27-35: 🛠️ Refactor suggestion

Consider enhancing error handling and adding duplicate checks in CreateAccount.

The CreateAccount method is well-structured, using prepared statements for security and performance. However, there are a few areas for improvement:

1. Error handling could be more descriptive. Consider wrapping errors with additional context.
2. There's no check for existing accounts before insertion, which could lead to duplicates.

Consider refactoring the method like this:

func (r *AccountRepository) CreateAccount(account *models.Account) error {
    // Check if account already exists
    existingAccount, err := r.GetAccountByUserID(account.UserID)
    if err != nil && !errors.Is(err, sql.ErrNoRows) {
        return fmt.Errorf("error checking existing account: %w", err)
    }
    if existingAccount != nil {
        return errors.New("account already exists for this user")
    }

    stmt, err := r.db.PrepareNamed(createAccountSQL)
    if err != nil {
        return fmt.Errorf("error preparing statement: %w", err)
    }
    defer stmt.Close()

    row := stmt.QueryRowxContext(r.ctx, account)
    if err := row.Scan(&account.ID); err != nil {
        return fmt.Errorf("error creating account: %w", err)
    }
    return nil
}

This refactoring adds a check for existing accounts and improves error handling with more context.

⚠️ Potential issue

Address the TODO comment and enhance error handling in GetBalance.

The GetBalance method is well-structured, but there are two main points to address:

1. The TODO comment suggests using a transaction to fix the table state. This is important for ensuring data consistency in concurrent scenarios.
2. Error handling could be more descriptive.

Implement the transaction as suggested in the TODO comment to ensure data consistency.

Consider refactoring the method like this:

func (r *AccountRepository) GetBalance(userID int64) (*models.Balance, error) {
    balance := &models.Balance{}
    err := r.db.WithTx(r.ctx, func(tx *sql.Tx) error {
        row := tx.QueryRowxContext(r.ctx, getBalanceSQL, userID)
        if err := row.StructScan(balance); err != nil {
            if errors.Is(err, sql.ErrNoRows) {
                return fmt.Errorf("no balance found for user ID %d", userID)
            }
            return fmt.Errorf("error scanning balance: %w", err)
        }
        return nil
    })
    if err != nil {
        return nil, fmt.Errorf("error getting balance: %w", err)
    }
    return balance, nil
}

This refactoring addresses the transaction issue and improves error handling with more context.

internal/token/middleware.go (1)

37-84: 🛠️ Refactor suggestion

Improve error handling, logging, and code structure in the Middleware function.

While the Middleware function correctly handles authentication, there are several areas where it can be improved:

1. Error handling:

   • Consider using custom error types for different authentication failures to provide more specific error messages.
   • Implement a consistent error response format across all error cases.

2. Logging:

   • Add more detailed logging throughout the function to aid in debugging and monitoring.
   • Log important events such as successful authentications and specific failure reasons.

3. Code structure:

   • Consider breaking down the function into smaller, more focused helper functions to improve readability and maintainability.

4. Security:

   • Implement rate limiting to prevent brute force attacks on the authentication endpoint.

Here's an example of how you might refactor a part of the function:

func (a *Authenticator) Middleware(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        tknString, err := a.extractToken(r)
        if err != nil {
            a.handleAuthError(w, err)
            return
        }

        userID, err := a.validateToken(tknString)
        if err != nil {
            a.handleAuthError(w, err)
            return
        }

        user, err := a.getUser(r.Context(), userID)
        if err != nil {
            a.handleAuthError(w, err)
            return
        }

        newR := r.WithContext(context.WithValue(r.Context(), UserKey, user))
        next.ServeHTTP(w, newR)
    })
}

func (a *Authenticator) extractToken(r *http.Request) (string, error) {
    // Implementation
}

func (a *Authenticator) validateToken(tknString string) (int64, error) {
    // Implementation
}

func (a *Authenticator) getUser(ctx context.Context, userID int64) (*User, error) {
    // Implementation
}

func (a *Authenticator) handleAuthError(w http.ResponseWriter, err error) {
    // Implementation
}

This refactoring would improve the overall structure and readability of the code.

40-48: ⚠️ Potential issue

Consider security implications of embedding JWT keys.

While using //go:embed is correct for including file contents at compile time, embedding sensitive data like JWT keys directly in the binary can pose security risks. Consider these alternatives:

1. Load keys from environment variables or secure key management systems at runtime.
2. If embedding is necessary, ensure the binary is properly secured and access to it is strictly controlled.

Additionally, implement key rotation mechanisms to enhance security.

Enhance API metadata for better documentation and accessibility.

Consider the following improvements to the API metadata:

1. Update the host field to reflect the production environment instead of localhost:8080.
2. Add contact information in the info.contact object to provide a point of contact for API-related queries.
3. Consider providing an English translation of the API description to improve accessibility for non-Russian speakers.
4. Add more detailed information about the API, such as its purpose, main features, and any authentication requirements.

Here's an example of how you could enhance the metadata:

⚠️ Potential issue

API endpoints are well-defined, but security measures are missing.

The API endpoints cover the necessary functionality for the GoFemart system, using appropriate HTTP methods and status codes. However, there are some areas for improvement:

1. Security: The API lacks security definitions and requirements. This is a critical issue flagged by static analysis tools.
2. Pagination: Consider adding pagination for list endpoints (e.g., /api/user/orders and /api/user/withdrawals).
3. Filtering: Some endpoints might benefit from query parameters for filtering results.

To address the security concerns, add a security definition and apply it to all endpoints. Here's an example using JWT authentication:

securityDefinitions:
  JWT:
    type: apiKey
    in: header
    name: Authorization

security:
  - JWT: []

Then, add the security requirement to each path:

paths:
  /api/user/balance:
    get:
      security:
        - JWT: []
      # ... rest of the endpoint definition

For pagination and filtering, consider adding query parameters to the relevant endpoints. For example:

/api/user/orders:
  get:
    parameters:
      - in: query
        name: page
        type: integer
        description: Page number for pagination
      - in: query
        name: limit
        type: integer
        description: Number of items per page
      - in: query
        name: status
        type: string
        description: Filter orders by status
    # ... rest of the endpoint definition

Apply similar changes to other list endpoints as needed.

api/swagger.json (1)

200-267: ⚠️ Potential issue

Improve /api/user/orders POST endpoint definition

The current definition for the POST request body is overly simplistic and might lead to confusion or misuse.

Consider changing the request body schema to an object for better clarity and future extensibility:

-        "schema": {
-            "type": "string"
-        }
+        "schema": {
+            "type": "object",

+            },
+            "required": ["order_number"]
+        }

Also, the success response (status 200) is using ErrorResponseBody, which seems incorrect for a successful operation.

Consider defining a proper success response schema:

-        "schema": {
-            "$ref": "#/definitions/payloads.ErrorResponseBody"
-        }
+        "schema": {
+            "type": "object",
+            "properties": {
+                "message": {

25-26: ⚠️ Potential issue

Use errors.As instead of errors.Is for type assertion

In the code snippet:

var tmrErr accrual.TooManyRequestError
if ok := errors.Is(err, &tmrErr); ok {

Using errors.Is with a pointer to tmrErr is not appropriate because errors.Is checks if an error is equal to a target error value, not a pointer. Since you want to check the error type and extract information, you should use errors.As.

Apply this diff to correct the error handling:

-var tmrErr accrual.TooManyRequestError
-if ok := errors.Is(err, &tmrErr); ok {
+var tmrErr *accrual.TooManyRequestError
+if errors.As(err, &tmrErr) {

This change uses errors.As to perform a type assertion on the error, allowing you to access tmrErr.PauseDuration safely.

if _, err := p.createNewAccount(order.Number, order.UserID, accrual.Accrual); err != nil {
    return err
}
order.StatusCode = models.StatusProcessed

If createNewAccount returns an error, the order status is not updated, and the function returns early. This may leave the order in an inconsistent state.

Consider handling the error without returning immediately or ensure that the order status is updated appropriately before returning. For example:

 if _, err := p.createNewAccount(order.Number, order.UserID, accrual.Accrual); err != nil {
+    // Set order status to indicate failure if necessary
+    order.StatusCode = models.StatusFailed
     return err

Review nested route groups for potential redundancy

At lines 38 and 54, route groups are nested within each other:

• Line 38: r.Group(registerRoutesWithAuth(...)) within /api/user route.
• Line 54: r.Group(registerRoutesWithCompressed(oHandlers)) inside registerRoutesWithAuth.

This nesting might introduce complexity and potential redundancy, especially since compression middleware is applied in both groups.

Consider restructuring the routing logic to simplify the hierarchy and ensure middleware is applied appropriately without overlapping.

Also applies to: 54-54

---

49-49: ⚠️ Potential issue

Avoid redundant application of compression middleware

Compression middleware is applied both in registerRoutesWithAuth at line 49 and in registerRoutesWithCompressed at line 63. This may lead to redundant compression processing.

Consider applying the compression middleware only where necessary to optimize performance. If the intent is to apply stronger compression to specific routes, ensure that the configuration reflects this appropriately.

Potential race condition when deleting user mutex during concurrent access.

Deleting the mutex after unlocking it in the deferred function may lead to race conditions. If another goroutine attempts to acquire the mutex for the same user after it has been deleted but before it's re-initialized, it can cause unexpected behavior. Consider maintaining the mutex for the user's lifetime or implementing a reference counting mechanism to safely manage the mutex lifecycle without deleting it immediately.

Review the use of HTTP status codes in WithdrawHandler

1. Luhn Check Failure: When the Luhn algorithm check fails, the handler returns HTTP status code 422 Unprocessable Entity. While this is acceptable, consider providing a more descriptive error message or using 400 Bad Request for input validation failures.

2. Order Already Exists: Returning 422 Unprocessable Entity when an order already exists might not be the most appropriate choice. Consider using 409 Conflict to indicate a resource conflict.

3. Insufficient Funds: The handler returns 402 Payment Required when the user has insufficient funds. The 402 status code is reserved for future use. It's better to use 403 Forbidden or 409 Conflict to indicate that the request cannot be completed due to business logic constraints.

4. Successful Withdrawal Response: On a successful withdrawal, the handler sends a response with the message "Success" and status code 200 OK. It's common practice to return a 204 No Content status code with an empty body for actions that alter server state but don't need to return a response body.

Avoid sending a response body with HTTP 204 No Content status

When no orders are found, the response uses http.StatusNoContent but includes a message body. According to the HTTP specification, a 204 No Content response should not include a body.

Consider changing the status code to http.StatusOK and returning an empty array, or adjust the implementation to omit the response body when using http.StatusNoContent.

Avoid setting JWT tokens in the Authorization header of responses

Setting the JWT token in the Authorization header of the HTTP response is unconventional and may lead to security vulnerabilities. Typically, tokens should be included in the response body or set as HTTP-only cookies to prevent interception or misuse.

Apply this diff to remove setting the Authorization header:

-	response.Header().Set("Authorization", "Bearer "+tkn)

Also applies to: 218-219

132-135: ⚠️ Potential issue

Enhance password hashing for improved security

The current implementation uses a hash key (l.hashKey) for password hashing, which may not be sufficiently secure if not managed properly. It is recommended to use established password hashing algorithms like bcrypt or Argon2, which handle salting and key stretching internally, providing robust protection against password cracking.

Consider refactoring the password hashing mechanism. For example:

import "golang.org/x/crypto/bcrypt"

// In GeneratePasswordHash method
hashedPassword, err := bcrypt.GenerateFromPassword([]byte(user.Password), bcrypt.DefaultCost)
if err != nil {
	return err
}
user.PasswordHash = string(hashedPassword)

---

189-191: ⚠️ Potential issue

Standardize authentication error messages to prevent user enumeration

Providing specific error messages like "password and login are incorrect" can aid attackers in determining valid usernames. To enhance security, consider using a generic error message for all authentication failures.

Apply this diff to update the error messages:

-	helpers.ProcessResponseWithStatus("password and login are incorrect", http.StatusUnauthorized, response)
+	helpers.ProcessResponseWithStatus("invalid credentials", http.StatusUnauthorized, response)

Also applies to: 199-201

---

193-197: ⚠️ Potential issue

Fix incorrect password validation logic

In the LoginHandler, the password validation logic incorrectly compares the hashed password provided by the user instead of the plaintext password. The CheckPasswordHash method expects the plaintext password to hash and compare with the stored hash. Passing the hashed password will result in authentication failures.

Apply this diff to fix the issue:

-	ok, err := dbUser.CheckPasswordHash(requestedUser.PasswordHash)
+	ok, err := dbUser.CheckPasswordHash(requestedUser.Password)

Consider removing this commented-out code if it's no longer necessary.

---

39-96: ⚠️ Potential issue

Eliminate Unused Functions parseFromEnv and parseFromCli

The functions parseFromEnv (lines 39-96) and parseFromCli (lines 98-124) are defined but not utilized anywhere in the codebase. Maintaining unused functions can lead to confusion and increase maintenance overhead.

Recommend removing these unused functions to streamline the codebase.

Also applies to: 98-124

Refactor bindEnv Function to Reduce Code Duplication

The bindEnv function (lines 195-245) contains repetitive code for binding environment variables to configuration keys. This repetition can be refactored to improve maintainability and readability.

Proposed refactor:

func bindEnv() error {
    envBindings := map[string]string{
        "Address":             "RUN_ADDRESS",
        "LogLevel":            "LOG_LEVEL",
        "DatabaseDSN":         "DATABASE_URI",
        "AccrualSystemAddress": "ACCRUAL_SYSTEM_ADDRESS",
        "HashKey":             "KEY",
        "PrivateKeyPath":      "PKEYP",
        "PublicKeyPath":       "PUKEYP",
        "PrivateKey":          "PKEY",
        "PublicKey":           "PUKEY",
        "TokenExpiration":     "TOKEN_EXPIRATION",
        "AccrualSenderPause":  "ACCRUAL_SENDER_PAUSE",
        "QueueSize":           "QUEUE_SIZE",
        "WorkerCount":         "WORKER_COUNT",
        "DBCheckDuration":     "DB_CHECK_DURATION",
        "DBMaxConnections":    "DB_MAX_CONNECTIONS",
        "DBMaxIdleConnections":"DB_MAX_IDLE_CONNECTIONS",
    }

    for key, envVar := range envBindings {
        if err := viper.BindEnv(key, envVar); err != nil {
            return err
        }
    }
    return nil
}

This refactor uses a map to associate configuration keys with their corresponding environment variables, reducing repetition and enhancing clarity.

Security Concern: Loading Private Keys from Environment Variables

In the parseKeysFromFile function (lines 140-180), the code allows loading private keys directly from environment variables or command-line arguments. Storing private keys in environment variables or passing them via command-line arguments can pose security risks, as they may be exposed in process listings or environment dumps.

Consider restricting the method of providing private keys to file paths only, or ensure that appropriate security measures are in place to protect keys supplied via environment variables. Implementing secure secret management practices can help mitigate potential risks.

---

141-146: ⚠️ Potential issue

Correct Error Messages to Reflect Missing Keys Accurately

The error messages in parseKeysFromFile (lines 142 and 145) state "no private key path specified" and "no public key path specified," even when both the key path and the key string are empty. This can be misleading.

Update the error messages to accurately reflect the condition being checked:

if privateKeyPath == "" && privateKey == "" {
-    return nil, nil, errors.New("no private key path specified")
+    return nil, nil, errors.New("no private key provided")
}
if publicKeyPath == "" && publicKey == "" {
-    return nil, nil, errors.New("no public key path specified")
+    return nil, nil, errors.New("no public key provided")
}

This change ensures that the error messages convey the correct reason for the failure.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

	if privateKeyPath == "" && privateKey == "" {
		return nil, nil, errors.New("no private key provided")

	if publicKeyPath == "" && publicKey == "" {
		return nil, nil, errors.New("no public key provided")

Tip

For best results, initiate chat on the files or code changes.

@kodermax: Я провел анализ кода и хотел бы предложить некоторые улучшения:

1. GitHub Actions Workflows:

   • В файле .github/workflows/gophermart.yml версия Go изменена с golang:1.23 на golang:1.22. Рекомендую использовать последнюю стабильную версию Go для получения последних обновлений и улучшений.
   • В файле .github/workflows/migrations.yml убедитесь, что конфиденциальные данные, такие как строка подключения к базе данных, не хранятся в открытом виде. Рекомендуется использовать секреты GitHub Actions (secrets) для защиты подобных данных.

2. Dockerfile и Docker Compose:

   • В deployments/docker/go/Dockerfile рассмотрите возможность использования многоэтапной сборки для уменьшения размера итогового Docker-образа. Например, соберите приложение в промежуточном этапе, а затем скопируйте бинарный файл в минимальный образ alpine или scratch.
   • В docker-compose.yml убедитесь, что переменные окружения с паролями и другими секретами не хранятся напрямую в файле. Используйте .env файл или секреты Docker Compose для безопасного управления конфиденциальной информацией.

3. Логирование:

   • В internal/logger/logger.go убедитесь, что в логах не записываются чувствительные данные, такие как пароли или личная информация пользователей.
   • Рассмотрите возможность использования структурированного логирования для облегчения последующего анализа и фильтрации логов.

4. Обработка ошибок и устойчивость:

   • В internal/accrual/proxy.go добавьте обработку тайм-аутов для HTTP-запросов к внешним сервисам, чтобы избежать зависаний при недоступности сервиса.
   • Реализуйте механизм повторных попыток с экспоненциальной задержкой при временных ошибках соединения.

5. Безопасность:

   • В internal/handlers/login/handlers.go и internal/models/user.go для хеширования паролей рекомендуется использовать устоявшиеся библиотеки, такие как bcrypt, вместо использования собственных реализаций на базе HMAC SHA-256.
   • Убедитесь, что JWT-токены создаются и проверяются безопасно, а ключи подписи хранятся в защищенном месте.

6. Тестирование:

   • Добавьте больше модульных тестов для критически важных частей приложения, таких как обработчики HTTP-запросов и взаимодействие с базой данных.
   • В файлах тестов убедитесь, что покрываете как позитивные, так и негативные сценарии использования функций.

7. Документация:

   • Убедитесь, что файлы api/docs.go, api/swagger.json и api/swagger.yaml синхронизированы между собой. Рассмотрите автоматическую генерацию документации из аннотаций в коде с использованием инструментов, таких как swaggo/swag.
   • Добавьте инструкции по развертыванию и использованию приложения в README.md для облегчения работы другим разработчикам.

8. Качество кода и оптимизация:

   • В internal/luna/luna.go рассмотрите возможность использования существующих библиотек для проверки номеров по алгоритму Луна, чтобы уменьшить вероятность ошибок и повысить надежность.
   • В конфигурационных файлах убедитесь, что значения по умолчанию логически обоснованы и могут быть переопределены через переменные окружения для различной среды выполнения.

Если у вас есть вопросы или нужна дополнительная помощь, пожалуйста, дайте знать.
