There's no error reporting at all even for wrong URLs. I mistakenly used a wrong URL (.com instead of .org) for my server to clone/push/pull/sync and was wondering why it doesn't sync.

Here's an example session:

I've tracked this down to http_exchange function in http.c. It correctly identifies non-200 HTTP responses:

      if( rc!=200 ) goto write_err;

However, it just goes to write_err where it simply closes the connection and doesn't output errors (perhaps, it should panic after closing the connection?), so Fossil just continues creating a new repository with zero data.

Perhaps, something like this would do:

--- src/http.c
+++ src/http.c
@@ -235,7 +235,7 @@
   /*
   ** Jump to here if an error is seen.
   */
 write_err:
   transport_close();
-  return;
+  fossil_panic("bad server response");
 }
