Subject: [PATCH v4 01/12] pkt-line: eliminate the need for static buffer in packet_write_gently()
Date: Wed, 17 Feb 2021 21:48:37 +0000	[thread overview]
Message-ID: <2d6858b1625aa3c96688c6c6a9157c2d2b16f43e.1613598529.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.766.v4.git.1613598529.gitgitgadget@gmail.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Teach `packet_write_gently()` to write the pkt-line header and the actual
buffer in 2 separate calls to `write_in_full()` and avoid the need for a
static buffer, thread-safe scratch space, or an excessively large stack
buffer.

Change the API of `write_packetized_from_fd()` to accept a scratch space
argument from its caller to avoid similar issues here.

These changes are intended to make it easier to use pkt-line routines in
a multi-threaded context with multiple concurrent writers writing to
different streams.
