From 7d3c71ddbf346bb5182d1cbb4610b9b575b34491 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 24 Sep 2024 18:06:38 -0400 Subject: [PATCH] http-push: free transfer_request dest field When we issue a PUT request, we store the destination in the "dest" field by detaching from a strbuf. But we never free the result, causing a leak. We can address this in the release_request() function. But note that we also need to initialize it to NULL, as most other request types do not set it at all. Curiously there are _two_ functions to initialize a transfer_request struct. Adding the initialization only to add_fetch_request() seems to be enough for t5540, but I won't pretend to understand why. Rather than just adding "request->dest = NULL" in both spots, let's zero the whole struct. That addresses this problem, as well as any future ones (and it can't possibly hurt, as by definition we'd be hitting uninitialized memory previously). This fixes several leaks noticed by t5540.
