-
-// Utilities for syscall testing.
-//
-// Initialization
-// ==============
-//
-// Prior to calling RUN_ALL_TESTS, all tests must use TestInit(&argc, &argv).
-// See the TestInit function for exact side-effects and semantics.
-//
-// Configuration
-// =============
-//
-// IsRunningOnGvisor returns true if the test is known to be running on gVisor.
-// GvisorPlatform can be used to get more detail:
-//
-// if (GvisorPlatform() == Platform::kPtrace) {
-// ...
-// }
-//
-// SetupGvisorDeathTest ensures that signal handling does not interfere with
-/// tests that rely on fatal signals.
-//
-// Matchers
-// ========
-//
-// ElementOf(xs) matches if the matched value is equal to an element of the
-// container xs. Example:
-//
-// // PASS
-// EXPECT_THAT(1, ElementOf({0, 1, 2}));
-//
-// // FAIL
-// // Value of: 3
-// // Expected: one of {0, 1, 2}
-// // Actual: 3
-// EXPECT_THAT(3, ElementOf({0, 1, 2}));
-//
-// SyscallSucceeds() matches if the syscall is successful. A successful syscall
-// is defined by either a return value not equal to -1, or a return value of -1
-// with an errno of 0 (which is a possible successful return for e.g.
-// PTRACE_PEEK). Example:
-//
-// // PASS
-// EXPECT_THAT(open("/dev/null", O_RDONLY), SyscallSucceeds());
-//
-// // FAIL
-// // Value of: open("/", O_RDWR)
-// // Expected: not -1 (success)
-// // Actual: -1 (of type int), with errno 21 (Is a directory)
-// EXPECT_THAT(open("/", O_RDWR), SyscallSucceeds());
-//
-// SyscallSucceedsWithValue(m) matches if the syscall is successful, and the
-// value also matches m. Example:
-//
-// // PASS
-// EXPECT_THAT(read(4, buf, 8192), SyscallSucceedsWithValue(8192));
-//
-// // FAIL
-// // Value of: read(-1, buf, 8192)
-// // Expected: is equal to 8192
-// // Actual: -1 (of type long), with errno 9 (Bad file number)
-// EXPECT_THAT(read(-1, buf, 8192), SyscallSucceedsWithValue(8192));
-//
-// // FAIL
-// // Value of: read(4, buf, 1)
-// // Expected: is > 4096
-// // Actual: 1 (of type long)
-// EXPECT_THAT(read(4, buf, 1), SyscallSucceedsWithValue(Gt(4096)));
-//
-// SyscallFails() matches if the syscall is unsuccessful. An unsuccessful
-// syscall is defined by a return value of -1 with a non-zero errno. Example:
-//
-// // PASS
-// EXPECT_THAT(open("/", O_RDWR), SyscallFails());
-//
-// // FAIL
-// // Value of: open("/dev/null", O_RDONLY)
-// // Expected: -1 (failure)
-// // Actual: 0 (of type int)
-// EXPECT_THAT(open("/dev/null", O_RDONLY), SyscallFails());
-//
-// SyscallFailsWithErrno(m) matches if the syscall is unsuccessful, and errno
-// matches m. Example:
-//
-// // PASS
-// EXPECT_THAT(open("/", O_RDWR), SyscallFailsWithErrno(EISDIR));
-//
-// // PASS
-// EXPECT_THAT(open("/etc/passwd", O_RDWR | O_DIRECTORY),
-// SyscallFailsWithErrno(AnyOf(EACCES, ENOTDIR)));
-//
-// // FAIL
-// // Value of: open("/dev/null", O_RDONLY)
-// // Expected: -1 (failure) with errno 21 (Is a directory)
-// // Actual: 0 (of type int)
-// EXPECT_THAT(open("/dev/null", O_RDONLY), SyscallFailsWithErrno(EISDIR));
-//
-// // FAIL
-// // Value of: open("/", O_RDWR)
-// // Expected: -1 (failure) with errno 22 (Invalid argument)
-// // Actual: -1 (of type int), failure, but with errno 21 (Is a directory)
-// EXPECT_THAT(open("/", O_RDWR), SyscallFailsWithErrno(EINVAL));
-//
-// Because the syscall matchers encode save/restore functionality, their meaning
-// should not be inverted via Not. That is, AnyOf(SyscallSucceedsWithValue(1),
-// SyscallSucceedsWithValue(2)) is permitted, but not
-// Not(SyscallFailsWithErrno(EPERM)).
-//
-// Syscalls
-// ========
-//
-// RetryEINTR wraps a function that returns -1 and sets errno on failure
-// to be automatically retried when EINTR occurs. Example:
-//
-// auto rv = RetryEINTR(waitpid)(pid, &status, 0);
-//
-// ReadFd/WriteFd/PreadFd/PwriteFd are interface-compatible wrappers around the
-// read/write/pread/pwrite syscalls to handle both EINTR and partial
-// reads/writes. Example:
-//
-// EXPECT_THAT(ReadFd(fd, &buf, size), SyscallSucceedsWithValue(size));
-//
-// General Utilities
-// =================
-//
-// ApplyVec(f, xs) returns a vector containing the result of applying function
-// `f` to each value in `xs`.
-//
-// AllBitwiseCombinations takes a variadic number of ranges containing integers
-// and returns a vector containing every integer that can be formed by ORing
-// together exactly one integer from each list. List<T> is an alias for
-// std::initializer_list<T> that makes AllBitwiseCombinations more ergonomic to
-// use with list literals (initializer lists do not otherwise participate in
-// template argument deduction). Example:
-//
-// EXPECT_THAT(
-// AllBitwiseCombinations<int>(
-// List<int>{SOCK_DGRAM, SOCK_STREAM},
-// List<int>{0, SOCK_NONBLOCK}),
-// Contains({SOCK_DGRAM, SOCK_STREAM, SOCK_DGRAM | SOCK_NONBLOCK,
-// SOCK_STREAM | SOCK_NONBLOCK}));
-//
-// VecCat takes a variadic number of containers and returns a vector containing
-// the concatenated contents.
-//
-// VecAppend takes an initial container and a variadic number of containers and
-// appends each to the initial container.
-//
-// RandomizeBuffer will use MTRandom to fill the given buffer with random bytes.
-//
-// GenerateIovecs will return the smallest number of iovec arrays for writing a
-// given total number of bytes to a file, each iovec array size up to IOV_MAX,
-// each iovec in each array pointing to the same buffer.
