From 768bdf1c210fd34776f667b080a23eb6f9e17125 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Fri, 10 May 2019 19:38:28 +0000 Subject: [PATCH] trace2: Add variable description to git.txt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Documentation/technical/api-trace2.txt contains the full details of the trace2 API and the GIT_TR2* environment variables. However, most environment variables are included in Documentation/git.txt, including the GIT_TRACE* variables. Add a brief description of the GIT_TR2* variables with links to the full technical details. The biggest difference from the original variables is that we can specify a Unix Domain Socket. Mention this difference, but leave the details to the technical documents.
