From: Matt Cooper <vtbassmatt@xxxxxxxxx> As a small courtesy to users, report what limit was breached. This is especially useful when a push exceeds a server-defined limit, since the user is unlikely to have configured the limit (their host did). Also demonstrate the human-readable message in a test. Helped-by: Taylor Blau <me@xxxxxxxxxxxx> Helped-by: Derrick Stolee <derrickstolee@xxxxxxxxxx> Signed-off-by: Matt Cooper <vtbassmatt@xxxxxxxxx> --- Specify the actual pack size limit which is breached Git allows configuring a maximum pack size. GitHub (like presumably other Git hosts) configures this setting to a generous but finite limit. When a user attempts to push an oversized pack, their connection is terminated with a message that they've exceeded the limit. The user has to find the limit value elsewhere, probably in the host's documentation. This change adds a small convenience -- specifying the limit itself in the error message -- so that users no longer have to search elsewhere to discover the limit. v2 squashes the changes into one commit and corrects the commit trailer misordering.
