Maybe callers of run-command should have to pass > an "ignore SIGPIPE" flag? I am of two minds. On the one hand, losing useful debugging information is not something we should do lightly. On the other hand, the message is really noise most of the time, even on servers: when pack-objects dies on the server side, it is most likely due to a connection that breaks (voluntarily or involuntarily) half-way during a transfer, and is presumably a frequent event, and as such not worth noting most of the time. > 2.

It did something weird on Windows until we added this line to compat/mingw.h: #define exit(code) exit((code) & 0xff) -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
