Subject: [PATCH v4 07/11] builtin/diagnose.c: create 'git diagnose' builtin
Date: Fri, 12 Aug 2022 20:10:15 +0000 [thread overview]
Message-ID: <b58d13325b2eaef32fac89fb2be8e29004560c45.1660335019.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1310.v4.git.1660335019.gitgitgadget@gmail.com>
From: Victoria Dye <vdye@github.com>
Create a 'git diagnose' builtin to generate a standalone zip archive of
repository diagnostics.
The "diagnose" functionality was originally implemented for Scalar in
aa5c79a331 (scalar: implement `scalar diagnose`, 2022-05-28). However, the
diagnostics gathered are not specific to Scalar-cloned repositories and
can be useful when diagnosing issues in any Git repository.

+================

+NAME
+----
+git-diagnose - Generate a zip archive of diagnostic information
+
+SYNOPSIS
+--------
+[verse]
+'git diagnose' [(-o | --output-directory) <path>] [(-s | --suffix) <format>]
+
+DESCRIPTION
+-----------
+Collects detailed information about the user's machine, Git client, and
+repository state and packages that information into a zip archive. The
+generated archive can then, for example, be shared with the Git mailing list to
+help debug an issue or serve as a reference for independent debugging.
+
+The following information is captured in the archive:
+
+ * 'git version --build-options'
+ * The path to the repository root
+ * The available disk space on the filesystem
+ * The name and size of each packfile, including those in alternate object
+ stores
+ * The total count of loose objects, as well as counts broken down by
+ `.git/objects` subdirectory
+
+This tool differs from linkgit:git-bugreport[1] in that it collects much more
+detailed information with a greater focus on reporting the size and data shape
+of repository contents.
+
+OPTIONS
+-------
+-o <path>::
+--output-directory <path>::
+ Place the resulting diagnostics archive in `<path>` instead of the
+ current directory.
+
+-s <format>::
+--suffix <format>::
+ Specify an alternate suffix for the diagnostics archive name, to create
+ a file named 'git-diagnostics-<formatted suffix>'. This should take the
+ form of a strftime(3) format string; the current local time will be
+ used.
+
+GIT

+Part of the linkgit:git[1] suite
