I was building under /W3, because CMake hadn't been set up to build
under /W4 -- therefore, I didn't see some warnings.
We also decided to remove the niebloids and instead break ADL by using
`= delete`, since otherwise we get warnings when we define a local
variable with the same name as a niebloid. I also removed `status` and
`symlink_status` from the `files` header, since it's unnecessary now,
and they're just implementation details of `RealFilesystem`.
I also removed some existing uses of unqualified `status(path)`, since
that no longer compiles. I also added `Filesystem::canonical`, to remove
another use of `fs::stdfs` in a function I was already working in.
There's a bug in `std::experimental::filesystem::status` on
libstdc++ -- it incorrectly sets its `error_code` when a file
doesn't exist, or when a path doesn't exist. In order to get
around this, `error_code` was cleared when the file doesn't exist,
but it was not cleared when the path didn't exist.
Note: in this case, I say "the file doesn't exist" when, if you
look up "a/b/c", "a/b" exists but "c" doesn't. I say "the path
doesn't exist" when, if you look up "a/b/c", either "a" or "a/b"
doesn't exist.
I added benchmarks to measure how fast the parallel remove_all code was
-- it turns out, about 3x slower than stdfs::remove_all. Since this was
the case, I removed all of the parallelism and rewrote it serially, and
ended up about 30% faster than stdfs::remove_all (in addition to
supporting symlinks).
In addition, I did the following three orthogonal changes:
- simplified the work queue, basing it on Billy O'Neal's idea
- Fix warnings on older versions of compilers in tests, by splitting
the pragmas out of pch.h.
- Ran clang-format on some files
In fixing up remove_all, the following changes were made:
- On Windows, regular symlinks and directory symlinks are distinct;
as an example, to remove directory symlinks (and junctions, for that
matter), one must use RemoveDirectory. Only on Windows, I added new
`file_type` and `file_status` types, with `file_type` including a new
`directory_symlink` enumerator, and `file_status` being exactly the
same as the old one except using the new `file_type`. On Unix, I
didn't make that change since they don't make a distinction.
- I added new `symlink_status` and `status` functions which use the
new `file_status` on Windows.
- I made `Filesystem::exists` call `fs::exists(status(p))`, as opposed
to the old version which called `stdfs::exists` directly.
- Added benchmarks to `vcpkg-test/files.cpp`. They test the
performance of `remove_all` on small directories (~20 files), with
symlinks and without, and on large directories (~2000 files), with
symlinks and without.
* better logic expression evaluation
Improve the logic expression evaluation currently used when filtering
dependencies.
Biggest improvements:
+ Allow '|' operator
+ Support nested '()'
+ Allow whitespace
+ Useful error message for malformed expressions
Also changed names of types to RawParagraph when that is what the original author was using.
This PR does the following:
* fix tests -- now, they're always built in the CMake scripts, and they work on VS2015
*add a new flag, BUILD_TESTING, which allows one to turn off testing builds
* Add documentation for running tests
- when an option is not recognized (perhaps because it has trailing whitespace characters), print it out enclosed with single quote to delimit and highlight potenatial not printable characters.
* begin exploratory rewriting of tests
* continue working on tests
* more test work! holy butts vcpkg-tests/plan.cpp was a bunch of work
* finish writing new tests
- [x] write catch2 tests
- [ ] rewrite/at least delete the VS project files
- [ ] document running tests
* Fix tests to work on WSL, rewrite test vcxproj
still need to test on macOS
also, delete tests.pch.h
* Condense add_test calls
* [vcpkg] Fix font corruption bug on Windows by downloading Powershell Core
* [vcpkg] Rename subtool to powershell-core
* [vcpkg] Add missing includes to project files
* Allow redirection of the scripts folder with an environment variable.
* - Updated feature from environment variable to argument.
* Fix crash when no scripts override is given and use --scripts-root=<PATH> format
* Update help messages to use --scripts-root=<PATH> format
* [vcpkg_configure_cmake] Add NO_CHARSET_FLAG option
* [vcpkg_configure_cmake] Add documentation for new NO_CHARSET_FLAG option
* [vcpkg_configure_cmake, windows toolchain] Handle NO_CHARSET_FLAG in toolchain

VS 2019 16.3 will contain a couple of source-breaking changes:
* <experimental/filesystem> will be deprecated via an
impossible-to-miss preprocessor "#error The <experimental/filesystem>
header providing std::experimental::filesystem is deprecated by
Microsoft and will be REMOVED. It is superseded by the C++17
<filesystem> header providing std::filesystem. You can define
_SILENCE_EXPERIMENTAL_FILESYSTEM_DEPRECATION_WARNING to acknowledge
that you have received this warning."
* <filesystem> will no longer include <experimental/filesystem>.
In the long term, I believe that vcpkg should detect when it's being
built with VS 2017 15.7 or newer, compile in C++17 mode, include
<filesystem>, and use std::filesystem. (Activating this for VS 2019 16.0
or newer would also be reasonable.) Similarly for other toolsets
supporting std::filesystem.
In the short term, this commit makes vcpkg compatible with the upcoming
deprecation. First, we need to define the silencing macro before
including the appropriate header. I've chosen to define it
unconditionally (without checking for platform or version), since it
has no effect for other platforms or versions. Second, we need to deal
with <filesystem> no longer including <experimental/filesystem>.
I verified that VS 2015 Update 3 contained <experimental/filesystem>
(back then, it simply included the <filesystem> header, where the
experimental implementation was defined; this was later reorganized).
Therefore, all of vcpkg's supported MSVC toolsets have
<experimental/filesystem>, so we can simply always include it.
I've verified that this builds with both VS 2015 Update 3 and
VS 2019 16.1.3 (the current production version).

* [vcpkg] Improve error handling in vcpkg::Files::Filesystem
Always require either std::error_code or LineInfo to print better errors.
* [vcpkg] Fixup missing return value.
Drive by fix: silence warnings in tests.

lld on Linux can now process #pragma comment(lib, "foo") macros which
results in build failures on Linux when lld is used. Fix this by
protecting these macros with _WIN32 checks.
* [control file] Add optional 'Homepage' tag
This allows a 'Homepage' tag to be added to a port in order to support
changes such as PR #2933. It currently does not do anything with it.
* [docs]
Add Homepage to the control file documentation
* move urls from descriptions to homepage field.
