// Notes(rfindley): ModuleResolver appears to be heavily optimized for scanning
// as fast as possible, which is desirable for a call to goimports from the
// command line, but it doesn't work as well for gopls, where it suffers from
// slow startup (golang/go#44863) and intermittent hanging (golang/go#59216),
// both caused by populating the cache, albeit in slightly different ways.
//
// A high level list of TODOs:
// - Optimize the scan itself, as there is some redundancy statting and

// - Invert the relationship between ProcessEnv and Resolver (see the

// - Make it easier to use an external resolver implementation.
//
// Smaller TODOs are annotated in the code below.
// ModuleResolver implements the Resolver interface for a workspace using

under a 2-clause BSD license (license text in the source files). The
included version has been heavily modified by Rich Felker in 2012, in
the interests of size, simplicity, and namespace cleanliness.

and labelled as such in comments in the individual source files. All
have been licensed under extremely permissive terms.
The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
The Android Open Source Project and is licensed under a two-clause BSD
license. It was taken from Bionic libc, used on Android.
The AArch64 memcpy and memset code (src/string/aarch64/*) are
Copyright © 1999-2019, Arm Limited.
The implementation of DES for crypt (src/crypt/crypt_des.c) is
Copyright © 1994 David Burren. It is licensed under a BSD license.
The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
originally written by Solar Designer and placed into the public
domain. The code also comes with a fallback permissive license for use
in jurisdictions that may not recognize the public domain.
The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
Valentin Ochs and is licensed under an MIT-style license.
The x86_64 port was written by Nicholas J. Kain and is licensed under
the standard MIT terms.
The mips and microblaze ports were originally written by Richard
Pennington for use in the ellcc project. The original code was adapted
by Rich Felker for build system and code conventions during upstream
integration. It is licensed under the standard MIT terms.
The mips64 port was contributed by Imagination Technologies and is
licensed under the standard MIT terms.
The powerpc port was also originally written by Richard Pennington,
and later supplemented and integrated by John Spencer. It is licensed
under the standard MIT terms.
All other files which have no copyright comments are original works
produced specifically for use as part of this library, written either
by Rich Felker, the main author of the library, or by one or more
contibutors listed above. Details on authorship of individual files
can be found in the git version control history of the project. The
omission of copyright and license comments in each file is in the
interest of source tree size.
In addition, permission is hereby granted for all public header files
(include/* and arch/*/bits/*) and crt files intended to be linked into
applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit
the copyright notice and permission notice otherwise required by the
license, and to use these files without any requirement of
attribution. These files include substantial contributions from:

John Spencer
Nicholas J. Kain
Rich Felker
Richard Pennington

Szabolcs Nagy
all of whom have explicitly granted such permission.
This file previously contained text expressing a belief that most of
the files covered by the above exception were sufficiently trivial not
to be subject to copyright, resulting in confusion over whether it
negated the permissions granted in the license. In the spirit of
permissive licensing, and of not having licensing issues being an
obstacle to adoption, that text has been removed.
