+ +This document describes the comprehensive pagination support implemented in the Yandex Disk Go client library. + +## Overview + +The pagination system provides multiple ways to handle large result sets from the Yandex Disk API: + +1. **Basic Pagination** - Simple offset/limit-based pagination +2. **Enhanced Pagination** - Pagination with metadata and status information +3. **Iterator Pattern** - Convenient iteration over paginated results +4. **Cursor-based Pagination** - Future-ready cursor support + +## API Methods with Pagination Support + +### GetSortedFiles + +Get a sorted list of files with pagination support. + +**Basic Usage:** +```go +// Get first 20 files (default) +files, err := client.GetSortedFiles(ctx) + +// Get with custom pagination +options := &disk.PaginationOptions{ + Limit: 10, + Offset: 20, +} +files, err := client.GetSortedFilesWithPagination(ctx, options) +``` + +**Enhanced Pagination:** +```go +options := &disk.PaginationOptions{Limit: 15} +pagedFiles, err := client.GetSortedFilesPaged(ctx, options) + +if err == nil { + fmt.Printf("Files: %d\n", len(pagedFiles.Items)) + fmt.Printf("HasMore: %t\n", pagedFiles.Pagination.HasMore) + if pagedFiles.Pagination.HasMore { + fmt.Printf("NextOffset: %d\n", pagedFiles.Pagination.NextOffset) + } +} +``` + +**Iterator Pattern:** +```go +iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 10}) + +for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + break + } + + for _, file := range page.FilesResourceList.Items { + fmt.Printf("File: %s\n", file.Name) + } +} +``` + +### GetLastUploadedResources + +Get recently uploaded files with pagination. + +```go +// Basic pagination +files, err := client.GetLastUploadedResources(ctx) + +// With custom options +options := &disk.PaginationOptions{Limit: 5} +files, err := client.GetLastUploadedResourcesWithPagination(ctx, options) + +// Enhanced with pagination info +pagedFiles, err := client.GetLastUploadedResourcesPaged(ctx, options) + +// Iterator pattern +iterator := client.GetLastUploadedResourcesIterator(options) +``` + +### GetPublicResources + +Get public resources with pagination. + +```go +// Basic pagination +resources, err := client.GetPublicResources(ctx) + +// With custom options +options := &disk.PaginationOptions{Limit: 10} +resources, err := client.GetPublicResourcesWithPagination(ctx, options) + +// Enhanced with pagination info +pagedResources, err := client.GetPublicResourcesPaged(ctx, options) + +// Iterator pattern +iterator := client.GetPublicResourcesIterator(options) +``` + +## Pagination Options + +### PaginationOptions Structure + +```go +type PaginationOptions struct { + Limit int // Maximum number of items to return (default: 20, max: 10000) + Offset int // Number of items to skip from the beginning (default: 0) + Cursor string // Cursor for cursor-based pagination (optional) +} +``` + +### Default Values + +- **Limit**: 20 items per page +- **Offset**: 0 (start from beginning) +- **Maximum Limit**: 10000 items per page + +### Validation + +All pagination options are automatically validated: +- Negative or zero limits default to 20 +- Limits exceeding 10000 are capped at 10000 +- Negative offsets are set to 0 + +## Pagination Information + +### PaginationInfo Structure + +```go +type PaginationInfo struct { + Limit int // Number of items requested + Offset int // Number of items skipped + Total int // Total number of items available (when available) + HasMore bool // Whether there are more items available + NextOffset int // Offset for the next page + NextCursor string // Cursor for the next page (cursor-based pagination) + PrevCursor string // Cursor for the previous page (cursor-based pagination) +} +``` + +## Iterator Patterns + +### Basic Iterator + +```go +iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 25}) + +for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + log.Printf("Error: %v", err) + break + } + + // Process page.FilesResourceList.Items + for _, file := range page.FilesResourceList.Items { + fmt.Printf("Processing: %s\n", file.Name) + } + + // Optional: Add delay to respect rate limits + time.Sleep(200 * time.Millisecond) +} +``` + +### Iterator Management + +```go +iterator := client.GetSortedFilesIterator(nil) + +// Change page size +iterator.SetPageSize(50) + +// Check current settings +pageSize := iterator.GetPageSize() +currentOffset := iterator.GetCurrentOffset() + +// Reset to beginning +iterator.Reset() +``` + +### Cursor-based Iterator + +```go +fetcher := func(ctx context.Context, cursor string, limit int) (*disk.PagedFilesResourceList, string, error) { + // Custom fetcher implementation + // Return: (data, nextCursor, error) +} + +cursorIterator := disk.NewCursorPaginationIterator(client, fetcher, 20) + +for cursorIterator.HasNext() { + page, err := cursorIterator.Next(ctx) + if err != nil { + break + } + // Process page +} +``` + +## Advanced Usage Examples + +### Collecting All Results + +```go +func collectAllFiles(client *disk.Client, ctx context.Context) ([]*disk.Resource, error) { + var allFiles []*disk.Resource + + iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 100}) + + for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + return nil, err + } + + allFiles = append(allFiles, page.FilesResourceList.Items...) + + // Respect rate limits + time.Sleep(100 * time.Millisecond) + } + + return allFiles, nil +} +``` + +### Searching with Pagination + +```go +func searchFiles(client *disk.Client, ctx context.Context, pattern string) ([]*disk.Resource, error) { + var matches []*disk.Resource + + iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 50}) + + for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + return nil, err + } + + for _, file := range page.FilesResourceList.Items { + if strings.Contains(strings.ToLower(file.Name), strings.ToLower(pattern)) { + matches = append(matches, file) + } + } + + time.Sleep(200 * time.Millisecond) + } + + return matches, nil +} +``` + +### Custom Page Sizes + +```go +// Different page sizes for different use cases +smallPages := &disk.PaginationOptions{Limit: 5} // For UI display +mediumPages := &disk.PaginationOptions{Limit: 50} // For processing +largePages := &disk.PaginationOptions{Limit: 1000} // For bulk operations + +// Use with any paginated method +files1, _ := client.GetSortedFilesWithPagination(ctx, smallPages) +files2, _ := client.GetLastUploadedResourcesWithPagination(ctx, mediumPages) +files3, _ := client.GetPublicResourcesWithPagination(ctx, largePages) +``` + +## Best Practices + +### Rate Limiting + +Always add delays between API calls to respect rate limits: + +```go +iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 20}) + +for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + break + } + + // Process page... + + // Add delay between requests + time.Sleep(200 * time.Millisecond) +} +``` + +### Error Handling + +```go +iterator := client.GetSortedFilesIterator(nil) + +for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + log.Printf("Error fetching page: %v", err) + + // Decide whether to continue or abort + if isTemporaryError(err) { + time.Sleep(1 * time.Second) + continue + } else { + break + } + } + + // Process page... +} +``` + +### Context Cancellation + +```go +ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second) +defer cancel() + +iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 10}) + +for iterator.HasNext() { + select { + case <-ctx.Done(): + log.Printf("Operation cancelled: %v", ctx.Err()) + return + default: + page, err := iterator.Next(ctx) + if err != nil { + break + } + // Process page... + } +} +``` + +### Memory Management + +For large datasets, process pages individually rather than collecting all results: + +```go +// Good: Process each page individually +iterator := client.GetSortedFilesIterator(&disk.PaginationOptions{Limit: 100}) + +for iterator.HasNext() { + page, err := iterator.Next(ctx) + if err != nil { + break + } + + // Process and discard page + processFiles(page.FilesResourceList.Items) + // page goes out of scope and can be garbage collected +} + +// Avoid: Collecting all results in memory for large datasets +// var allFiles []*disk.Resource // This could consume too much memory +``` + +## Migration from Non-Paginated Methods + +The original methods are preserved for backward compatibility: + +```go +// Old way (still works) +files, err := client.GetSortedFiles(ctx) + +// New way with explicit pagination +files, err := client.GetSortedFilesWithPagination(ctx, &disk.PaginationOptions{Limit: 20}) + +// Enhanced way with pagination info +pagedFiles, err := client.GetSortedFilesPaged(ctx, &disk.PaginationOptions{Limit: 20}) +``` + +## Future Enhancements + +The pagination system is designed to support future API enhancements: + +1. **Cursor-based Pagination** - Ready for when the API supports cursors +2. **Total Count Support** - Will utilize total counts when available +3. **Sorting Options** - Can be extended to support different sort orders +4. **Filtering** - Framework ready for server-side filtering + +## Error Handling + +All pagination methods return appropriate error types: + +```go +files, errResp := client.GetSortedFilesWithPagination(ctx, options) +if errResp != nil { + switch errResp.Error { + case "UnauthorizedError": + // Handle authentication issues + case "LimitExceededError": + // Handle rate limiting + default: + // Handle other errors + } +} +``` + +## Performance Considerations + +1. **Page Size**: Balance between fewer requests (larger pages) and memory usage +2. **Rate Limits**: Always include delays between requests +3. **Context Timeouts**: Set appropriate timeouts for large operations +4. **Error Retry**: Implement retry logic for temporary failures +5. **Memory Usage**: Process pages individually for large datasets + +## Testing + +Comprehensive tests are provided for all pagination functionality: + +```bash +# Run pagination-specific tests +go test -v -run TestPagination + +# Run all tests to ensure compatibility +go test -v +``` + +## Examples + +See `examples/pagination_example.go` for a complete working example demonstrating all pagination features. \ No newline at end of file diff --git a/batch.go b/batch.go new file mode 100644 index
