[PATCH v2 00/10] Generalize 'scalar diagnose' into 'git diagnose' and 'git bugreport --diagnose'

["Victoria Dye via GitGitGadget" <gitgitgadget@gmail.com>]

As part of the preparation for moving Scalar out of 'contrib/' and into Git,
this series moves the functionality of 'scalar diagnose' into a new builtin
('git diagnose') and a new option ('--diagnose') for 'git bugreport'. This
change further aligns Scalar with the objective [1] of having it only
contain functionality and settings that benefit large Git repositories, but
not all repositories. The diagnostics reported by 'scalar diagnose' relevant
for investigating issues in any Git repository, so generating them should be
part of a "normal" Git builtin.

The series is organized as follows:

 * Miscellaneous fixes for the existing 'scalar diagnose' implementation
 * Moving the code for generating diagnostics into a common location in the
   Git tree
 * Implementing 'git diagnose'
 * Implementing 'git bugreport --diagnose'
 * Updating the Scalar roadmap

Finally, despite 'scalar diagnose' now being nothing more than a wrapper for
'git bugreport --diagnose', it is not being deprecated in this series.
Although deprecation -> removal could be a future cleanup effort, 'scalar
diagnose' is kept around for now as an alias for users already accustomed to
using it in 'scalar'.


Changes since V1
================

 * Reorganized patches to fix minor issues (e.g., more gently adding
   directories to the archive) of 'scalar diagnose' in 'scalar.c', before
   the code is moved out of that file.
 * (Almost) entirely redesigned the UI for generating diagnostics. The new
   approach avoids cluttering 'git bugreport' with a mode that doesn't
   actually generate a report. Now, there are distinct options for different
   use cases: generating extra diagnostics with a bug report ('git bugreport
   --diagnose') and generating diagnostics for personal debugging/addition
   to an existing bug report ('git diagnose').
 * Moved 'get_disk_info()' into 'compat/'.
 * Moved 'create_diagnostics_archive()' into a new 'diagnose.c', as it now
   has multiple callers.
 * Updated command & option documentation to more clearly guide users on how
   to use the new options.
 * Added the '--all' (and '--diagnose=all') option to change the default
   behavior of diagnostics generation to exclude '.git' directory contents.
   For many bug reporters, this would reveal private repository contents
   they don't want to expose to the public mailing list. This has the added
   benefit of creating much smaller archives by default, which will be more
   likely to successfully send to the mailing list.

Thanks!

 * Victoria

     -    scalar: use 'git bugreport --diagnose' in 'scalar diagnose'
     +    scalar-diagnose: move functionality to common location
      
     -    Replace implementation of 'scalar diagnose' with an internal invocation of
     -    'git bugreport --diagnose --no-report'. The '--diagnose' option of 'git
     -    bugreport' was implemented to mirror what 'scalar diagnose' does, taking
     -    most of its code directly from 'scalar.c'. Remove the now-duplicate code in
     -    'scalar.c' and have 'scalar diagnose' call 'git bugreport' to create the
     -    diagnostics archive.
     +    Move the core functionality of 'scalar diagnose' into a new 'diagnose.[c,h]'
     +    library to prepare for new callers in the main Git tree generating
     +    diagnostic archives. These callers will be introduced in subsequent patches.
      
     -    This introduces two (minor) changes to the output of 'scalar diagnose':
     -    changing "Enlistment root" to "Repository root" in 'diagnostics.log'
     -    ("enlistment root" was inaccurate anyway, as the reported path always
     -    pointed to the root of the repository), and changing the prefix of the zip
     -    archive from 'scalar_' to 'git-diagnostics-'.
     +    While this patch appears large, it is mostly made up of moving code out of
     +    'scalar.c' and into 'diagnose.c'. Specifically, the functions
     +
     +    - dir_file_stats_objects()
     +    - dir_file_stats()
     +    - count_files()
     +    - loose_objs_stats()
     +    - add_directory_to_archiver()
     +
     +    are all copied verbatim from 'scalar.c'. The 'create_diagnostics_archive()'
     +    function is a mostly identical (partial) copy of 'cmd_diagnose()', with the
     +    primary changes being that 'zip_path' is an input and "Enlistment root" is
     +    corrected to "Repository root" in the archiver log.

     @@ Commit message
          Create a '--diagnose' option for 'git bugreport' to collect additional
          information about the repository and write it to a zipped archive.
      
     -    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
     -    could be useful when diagnosing issues in any Git repository.
     +    The '--diagnose' option behaves effectively as an alias for simultaneously
     +    running 'git bugreport' and 'git diagnose'. In the documentation, users are
     +    explicitly recommended to attach the diagnostics alongside a bug report to
     +    provide additional context to readers, ideally reducing some back-and-forth
     +    between reporters and those debugging the issue.
      
     -    Note that, while this patch appears large, it is mostly copied directly out
     -    of 'scalar.c'. Specifically, the functions
     -
     -    - dir_file_stats_objects()
     -    - dir_file_stats()
     -    - count_files()
     -    - loose_objs_stats()
     -    - add_directory_to_archiver()
     -    - get_disk_info()
     -
     -    are all copied verbatim from 'scalar.c'. The 'create_diagnostics_archive()'
     -    function is a mostly unmodified copy of 'cmd_diagnose()', with the primary
     -    changes being that 'zip_path' is an input and "Enlistment root" is corrected
     -    to "Repository root" in the logs.
     -
     -    The remainder of the patch is made up of adding the '--diagnose' option to
     -    'cmd_bugreport()' (including generation of the archive's 'zip_path'),
     -    updating documentation, and adding a test. Note that the test is
     -    'test_expect_failure' due to bugs in the original 'scalar diagnose'. These
     -    will be fixed in subsequent patches.
     +    Note that '--diagnose' may take an optional string arg (either 'basic' or
     +    'all'). If specified without the arg or with 'basic', the behavior
     +    corresponds to running 'git diagnose' without '--all'; this default is meant
     +    to help reduce unintentional leaking of sensitive information). However, a
     +    user can still manually specify '--diagnose=all' to generate the equivalent
     +    archive to one created with 'git diagnose --all'.

     @@ Documentation/technical/scalar.txt: series have been accepted:
       - `scalar-diagnose`: The `scalar` command is taught the `diagnose` subcommand.
