[Libguestfs] [PATCH nbdkit v2 4/4] curl: Use the parallel thread model

NOTE! THIS PESSIMIZES PERFORMANCE: https://listman.redhat.com/archives/libguestfs/2023-February/030618.html After previous changes, it is now safe to use the parallel thread model in this plugin. The locking in pool.c protects a single curl handle from being used from multiple threads. An advantage of this is we can now combine the curl plugin with filters such as readahead and scan. --- plugins/curl/curl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/plugins/curl/curl.c b/plugins/curl/curl.c index 4634c7006..e7c0e18da 100644 --- a/plugins/curl/curl.c +++ b/plugins/curl/curl.c @@ -468,7 +468,7 @@ curl_close (void *handle) free (h); } -#define THREAD_MODEL NBDKIT_THREAD_MODEL_SERIALIZE_REQUESTS +#define THREAD_MODEL NBDKIT_THREAD_MODEL_PARALLEL /* Calls get_handle() ... put_handle() to get a handle for the length * of the current scope. -- 2.39.0
