Purpose
Linked issue: #164 .
Paimon enables REST with
find_package(CURL REQUIRED)and does not declare a minimum libcurl version. However,IsRetriableTransportErrorunconditionally referencesCURLE_HTTP2_STREAM, which was added in libcurl 7.49.0. Building REST support with an older supported libcurl, such as 7.46.0, therefore fails at compile time.Guard the enum case with
CURL_AT_LEAST_VERSION(7, 49, 0). Builds using libcurl 7.49 or newer retain the existing retry classification; older libcurl versions cannot return an error code they do not define.Tests
git diff --checkpasses.core_test: 1809/1809 passed.RestHttpClientTest.*: 26/26 passed.Coverage
The curl 7.46.0 build validates the pre-7.49 compile-time branch. Existing builds with newer libcurl retain the
CURLE_HTTP2_STREAMcase. No separate line or branch coverage report was generated.API and Format
