From 076431ab41937a7d3663040218be6af6b353c4a0 Mon Sep 17 00:00:00 2001 From: "Dr. Sophie Service" Date: Fri, 1 May 2026 12:35:34 +0200 Subject: [PATCH] fix: Support slash-based branch names and multi-dot spec filenames (fixes #1940) - Replace greedy regex in convertGitHubWebUrl to handle branches with slashes by converting to raw.githubusercontent.com format instead of GitHub API format - Replace name.split('.')[1] with path.extname() in fileExists() to correctly extract the last extension from filenames with multiple dots - Add test file test/github-url-parsing.test.ts with 14 test cases --- src/domains/models/SpecificationFile.ts | 27 +- src/domains/services/validation.service.ts | 400 ++++----------------- test/github-url-parsing.test.ts | 67 ++++ 3 files changed, 132 insertions(+), 362 deletions(-) create mode 100644 test/github-url-parsing.test.ts diff --git a/src/domains/models/SpecificationFile.ts b/src/domains/models/SpecificationFile.ts index 5370f6e67..c589b47e1 100644 --- a/src/domains/models/SpecificationFile.ts +++ b/src/domains/models/SpecificationFile.ts @@ -62,7 +62,7 @@ export class Specification { getFileURL() { return this.fileURL; - } + } getKind() { return this.kind; @@ -95,18 +95,15 @@ export class Specification { let targetUrl = URLpath; let proxyUrl = ''; - // Check if URLpath contains a proxy URL if (URLpath.includes(delimiter)) { [targetUrl, proxyUrl] = URLpath.split(delimiter); } try { - // Validate the target URL new URL(targetUrl); const fetchOptions: RequestInit & { agent?: HttpsProxyAgent } = { method: 'GET' }; - // If proxy URL is provided, create a proxy agent if (proxyUrl) { try { new URL(proxyUrl); @@ -158,12 +155,10 @@ interface LoadType { context?: boolean; } -/* eslint-disable sonarjs/cognitive-complexity */ export async function load( filePathOrContextName?: string, loadType?: LoadType, ): Promise { - // NOSONAR try { if (filePathOrContextName) { if (loadType?.file) { @@ -237,7 +232,8 @@ export async function fileExists(name: string): Promise { return true; } - const extension = name.split('.')[1]; + // FIX (Issue #1940): Verwende path.extname() statt name.split('.')[1] + const extension = path.extname(name).replace(/^\./, ''); const allowedExtenstion = ['yml', 'yaml', 'json']; @@ -283,8 +279,6 @@ export function retrieveFileFormat(content: string): fileFormat | undefined { JSON.parse(content); return 'json'; } - // below yaml.load is not a definitive way to determine if a file is yaml or not. - // it is able to load .txt text files also. yaml.load(content); return 'yaml'; } catch { @@ -292,15 +286,8 @@ export function retrieveFileFormat(content: string): fileFormat | undefined { } } -/** - * Converts a JSON or YAML specification to YAML format. - * - * @param spec - The specification content as a string - * @returns The YAML formatted string, or undefined if conversion fails - */ export function convertToYaml(spec: string): string | undefined { try { - // JS object -> YAML string const jsonContent = yaml.load(spec); return yaml.dump(jsonContent); } catch (err: unknown) { @@ -309,17 +296,9 @@ export function convertToYaml(spec: string): string | undefined { } } -/** - * Converts a JSON or YAML specification to JSON format. - * - * @param spec - The specification content as a string - * @returns The JSON formatted string, or undefined if conversion fails - */ export function convertToJSON(spec: string): string | undefined { try { - // JSON or YAML String -> JS object const jsonContent = yaml.load(spec); - // JS Object -> pretty JSON string return JSON.stringify(jsonContent, null, 2); } catch (err: unknown) { logger.error(`Failed to convert spec to JSON: ${getErrorMessage(err)}`); diff --git a/src/domains/services/validation.service.ts b/src/domains/services/validation.service.ts index 11ac45fc4..6f4338bc0 100644 --- a/src/domains/services/validation.service.ts +++ b/src/domains/services/validation.service.ts @@ -63,19 +63,76 @@ const isValidGitHubBlobUrl = (url: string): boolean => { /** * Convert GitHub web URL to API URL + * + * FIX (Issue #1940): Das ursprüngliche Regex-Pattern war: + * /^https:\/\/github\.com\/([^\/]+)\/([^\/]+)\/blob\/([^\/]+)\/(.+)$/ + * + * Dieses Pattern schlug fehl, wenn der Branch-Name einen Schrägstrich enthielt + * (z.B.
