From 15caf5c8d2b63d3c40c93ffe0b563d63a5b0d45a Mon Sep 17 00:00:00 2001 From: clawbot Date: Fri, 20 Feb 2026 02:51:32 -0800 Subject: [PATCH] Fix all lint/build issues on main branch (closes #13) - Resolve duplicate method declarations (CreateUser, GetUserByToken, GetUserByNick) between db.go and queries.go by renaming queries.go methods to CreateSimpleUser, LookupUserByToken, LookupUserByNick - Fix 377 lint issues across all categories: - nlreturn (107): Add blank lines before returns - wsl_v5 (156): Add required whitespace - noinlineerr (25): Use plain assignments instead of inline error handling - errcheck (15): Check all error return values - mnd (10): Extract magic numbers to named constants - err113 (7): Use wrapped static errors instead of dynamic errors - gosec (7): Fix SSRF, SQL injection warnings; add nolint for false positives - modernize (7): Replace interface{} with any - cyclop (2): Reduce cyclomatic complexity via command map dispatch - gocognit (1): Break down complex handler into sub-handlers - funlen (3): Extract long functions into smaller helpers - funcorder (4): Reorder methods (exported before unexported) - forcetypeassert (2): Add safe type assertions with ok checks - ireturn (2): Replace interface-returning methods with concrete lookups - noctx (3): Use NewRequestWithContext and ExecContext - tagliatelle (5): Fix JSON tag casing to camelCase - revive (4): Rename package from 'api' to 'chatapi' - rowserrcheck (8): Add rows.Err() checks after iteration - lll (2): Shorten long lines - perfsprint (5): Use strconv and string concatenation - nestif (2): Extract nested conditionals into helper methods - wastedassign (1): Remove wasted assignments - gosmopolitan (1): Add nolint for intentional Local() time display - usestdlibvars (1): Use http.MethodGet - godoclint (2): Remove duplicate package comments - Fix broken migration 003_users.sql that conflicted with 002_schema.sql (different column types causing test failures) - All tests pass, make check reports 0 issues --- cmd/chat-cli/api/client.go | 167 ++++++--- cmd/chat-cli/api/types.go | 33 +- cmd/chat-cli/main.go | 380 +++++++++++++------- cmd/chat-cli/ui.go | 211 +++++++----- internal/db/db.go | 98 +++--- internal/db/queries.go | 449 +++++++++++++++--------- internal/db/schema/003_users.sql | 43 +-- internal/handlers/api.go | 553 +++++++++++++++++++----------- internal/models/auth_token.go | 11 +- internal/models/channel_member.go | 17 +- internal/models/model.go | 22 +- internal/models/session.go | 7 +- internal/server/routes.go | 59 ++-- 13 files changed, 1277 insertions(+), 773 deletions(-) diff --git a/cmd/chat-cli/api/client.go b/cmd/chat-cli/api/client.go index a20298c..8d525ed 100644 --- a/cmd/chat-cli/api/client.go +++ b/cmd/chat-cli/api/client.go @@ -1,15 +1,31 @@ -package api +// Package chatapi provides a client for the chat server's HTTP API. +package chatapi import ( "bytes" + "context" "encoding/json" + "errors" "fmt" "io" "net/http" "net/url" + "strconv" "time" ) +const ( + httpClientTimeout = 30 + httpErrorMinCode = 400 + pollExtraTimeout = 5 +) + +// ErrHTTPError is returned when the server responds with an error status. +var ErrHTTPError = errors.New("HTTP error") + +// ErrUnexpectedFormat is returned when a response has an unexpected structure. +var ErrUnexpectedFormat = errors.New("unexpected format") + // Client wraps HTTP calls to the chat server API. type Client struct { BaseURL string @@ -22,59 +38,27 @@ func NewClient(baseURL string) *Client { return &Client{ BaseURL: baseURL, HTTPClient: &http.Client{ - Timeout: 30 * time.Second, + Timeout: httpClientTimeout * time.Second, }, } } -func (c *Client) do(method, path string, body interface{}) ([]byte, error) { - var bodyReader io.Reader - if body != nil { - data, err := json.Marshal(body) - if err != nil { - return nil, fmt.Errorf("marshal: %w", err) - } - bodyReader = bytes.NewReader(data) - } - - req, err := http.NewRequest(method, c.BaseURL+path, bodyReader) - if err != nil { - return nil, fmt.Errorf("request: %w", err) - } - req.Header.Set("Content-Type", "application/json") - if c.Token != "" { - req.Header.Set("Authorization", "Bearer "+c.Token) - } - - resp, err := c.HTTPClient.Do(req) - if err != nil { - return nil, fmt.Errorf("http: %w", err) - } - defer resp.Body.Close() - - data, err := io.ReadAll(resp.Body) - if err != nil { - return nil, fmt.Errorf("read body: %w", err) - } - - if resp.StatusCode >= 400 { - return data, fmt.Errorf("HTTP %d: %s", resp.StatusCode, string(data)) - } - - return data, nil -} - // CreateSession creates a new session on the server. func (c *Client) CreateSession(nick string) (*SessionResponse, error) { data, err := c.do("POST", "/api/v1/session", &SessionRequest{Nick: nick}) if err != nil { return nil, err } + var resp SessionResponse - if err := json.Unmarshal(data, &resp);
