This caused commands like `nix store info --store s3://bucket` to fail with "don't know how to open Nix store with scheme 's3'". This commit restores S3 support by: 1. Adding "s3" to HttpBinaryCacheStore's supported URI schemes when built with AWS CRT support 2.

This commit fixes two issues: 1. Query parameters in S3 store URLs (like ?region=us-east-2) were being treated as store settings instead of URL parameters, causing "unknown setting" warnings. 2. URL construction in makeRequest() was incorrectly concatenating paths with query parameters. The fix: - HttpBinaryCacheStoreConfig now preserves query parameters for S3 URLs - makeRequest() properly constructs URLs preserving query parameters without corrupting the path Now users can specify: s3://bucket?region=us-east-2 to access buckets in specific AWS regions. --- src/libstore/http-binary-cache-store.cc | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/src/libstore/http-binary-cache-store.cc b/src/libstore/http-binary-cache-store.cc index 2f3dc9d3462..e2df655a284 100644 --- a/src/libstore/http-binary-cache-store.cc +++ b/src/libstore/http-binary-cache-store.cc @@ -33,6 +33,12 @@ HttpBinaryCacheStoreConfig::HttpBinaryCacheStoreConfig( { while (!cacheUri.path.empty() && cacheUri.path.back() == '/') cacheUri.path.pop_back(); + + // For S3 stores, preserve query parameters as part of the URL + // These are needed for region specification and other S3-specific settings + if (scheme == "s3" && !params.empty()) { + cacheUri.query = params; + } } StoreReference HttpBinaryCacheStoreConfig::getReference() const @@ -170,10 +176,14 @@ class HttpBinaryCacheStore : public virtual BinaryCacheStore `std::filesystem::path`'s equivalent operator, which properly combines the the URLs, whether the right is relative or absolute. */ - return FileTransferRequest( - hasPrefix(path, "https://") || hasPrefix(path, "http://") || hasPrefix(path, "file://") - ? path - : config->cacheUri.to_string() + "/" + path); + if (hasPrefix(path, "https://") || hasPrefix(path, "http://") || hasPrefix(path, "file://")) { + return FileTransferRequest(path); + } else { + // Properly construct URL preserving query parameters + auto baseUrl = config->cacheUri; + baseUrl.path = baseUrl.path + "/" + path; + return FileTransferRequest(baseUrl.to_string()); + } } void getFile(const std::string & path, Sink & sink) override From eba11e5a3e44eb1679ef5957d20677c720e4bc38 Mon Sep 17 00:00:00 2001 From: Bernardo Meurer Costa Date: Fri, 15 Aug 2025 17:58:36 +0000 Subject: [PATCH 09/16] test(libstore): add regression tests for S3 fixes Add tests to prevent regression of S3 functionality: 1.

This addresses reviewer feedback requesting proper Error types instead of nullptr for authentication failures. Changes: - Add AwsAuthError exception class - Update AwsCredentialProvider methods to throw exceptions - Change getCredentials() to return AwsCredentials directly - Update all tests to handle exception-based API - Fix filetransfer.cc to catch AwsAuthError and continue for public buckets --- src/libstore-tests/aws-auth.cc | 122 +++++++++++---------- src/libstore-tests/s3-edge-cases.cc | 109 ++++++++++-------- src/libstore/aws-auth.cc | 43 ++++---- src/libstore/filetransfer.cc | 37 +++---- src/libstore/include/nix/store/aws-auth.hh | 12 +- 5 files changed, 178 insertions(+), 145 deletions(-) diff --git a/src/libstore-tests/aws-auth.cc b/src/libstore-tests/aws-auth.cc index 46797eb2df6..2e718fbd2bf 100644 --- a/src/libstore-tests/aws-auth.cc +++ b/src/libstore-tests/aws-auth.cc @@ -23,45 +23,58 @@ class AwsCredentialProviderTest : public ::testing::Test TEST_F(AwsCredentialProviderTest, createDefault) { - auto provider = AwsCredentialProvider::createDefault();
