From 287357ccaaab6705d2e7fcf34687281725cd72a7 Mon Sep 17 00:00:00 2001 From: Kenneth Kalmer Date: Mon, 8 Dec 2025 16:43:15 +0000 Subject: [PATCH] fix: add comprehensive redirect file validation and instrumentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses WEB-4839 by implementing a multi-layered approach to detect and prevent empty redirect files in CI builds. Key changes: 1. Added comprehensive logging using Gatsby's reporter infrastructure - Track redirect initialization, write attempts, and counts - Log GraphQL query results showing pages with redirect_from - Report hash fragment filtering - Re-initialization detection with warnings 2. Post-write validation in createPages - Validates redirect file after Promise.all completes - Compares expected vs actual redirect counts - Uses reporter.panicOnBuild() to fail builds immediately if empty 3. Build validation hook in onPostBuild - Safety net before build artifacts are published - Validates file existence, size, content, and format - Checks minimum redirect threshold (50+) 4. Enhanced CI validation - Comprehensive bash checks for file content - Counts redirects and validates minimum threshold - Shows file details if validation fails 5. Error handling improvements - Try-catch around all file operations - Proper error reporting with context - Prevents silent failures All logging now uses Gatsby's reporter for structured, colored output consistent with the rest of the codebase. This makes it impossible for empty redirect files to reach production silently. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .circleci/config.yml | 5 +- bin/assert-nginx-redirects.sh | 29 +++++++ data/createPages/index.ts | 20 ++++- data/createPages/writeRedirectToConfigFile.ts | 40 ++++++++- data/onPostBuild/index.ts | 30 ++++++- data/utils/validateRedirectFile.ts | 85 +++++++++++++++++++ 6 files changed, 199 insertions(+), 10 deletions(-) create mode 100755 bin/assert-nginx-redirects.sh create mode 100644 data/utils/validateRedirectFile.ts diff --git a/.circleci/config.yml b/.circleci/config.yml index 89a815ef02..2ad9210b01 100644 --- a/.circleci/config.yml +++ b/.circleci/config.yml @@ -123,8 +123,9 @@ jobs: ../bin/compile build /tmp mv build/bin/nginx ../bin/ - run: - name: Require redirects file to be generated - command: test -f config/nginx-redirects.conf + name: Require redirects file to be generated with content + command: | + ./bin/assert-nginx-redirects.sh - run: name: Verify all files are compressed command: ./bin/assert-compressed.sh diff --git a/bin/assert-nginx-redirects.sh b/bin/assert-nginx-redirects.sh new file mode 100755 index 0000000000..eacc2c9075 --- /dev/null +++ b/bin/assert-nginx-redirects.sh @@ -0,0 +1,29 @@ +#!/bin/bash + +# +# A utility script to assert that the nginx redirects configuration file exists and is valid +# +# Usage: assert-nginx-redirects.sh +# + +echo "Validating redirect file..." + +# Check file exists +if [ ! -f config/nginx-redirects.conf ];
