Compile Options

There are some cflags provided to change Puma’s default configuration for its
C extension.

Query String, `PUMA_QUERY_STRING_MAX_LENGTH`

By default, the max length of QUERY_STRING is 1024 * 10. But you may want to
adjust it to accept longer queries in GET requests.

For manual install, pass the PUMA_QUERY_STRING_MAX_LENGTH option like this:

gem install puma -- --with-cflags="-D PUMA_QUERY_STRING_MAX_LENGTH=64000"

For Bundler, use its configuration system:

bundle config build.puma "--with-cflags='-D PUMA_QUERY_STRING_MAX_LENGTH=64000'"

By default, the max length of REQUEST_PATH is 8192. But you may want to
adjust it to accept longer paths in requests.

For manual install, pass the PUMA_REQUEST_PATH_MAX_LENGTH option like this:

gem install puma -- --with-cflags="-D PUMA_REQUEST_PATH_MAX_LENGTH=64000"

For Bundler, use its configuration system:

bundle config build.puma "--with-cflags='-D PUMA_REQUEST_PATH_MAX_LENGTH=64000'"

By default, the max length of REQUEST_URI is 1024 * 12. But you may want to
adjust it to accept longer URIs in requests.

For manual install, pass the PUMA_REQUEST_URI_MAX_LENGTH option like this:

gem install puma -- --with-cflags="-D PUMA_REQUEST_URI_MAX_LENGTH=64000"

For Bundler, use its configuration system:

bundle config build.puma "--with-cflags='-D PUMA_REQUEST_URI_MAX_LENGTH=64000'"
