Andrew Kelley 227ead54be back to malloc instead of aligned_alloc for c_allocator
it seems that a 7 years old standard is still too new for the
libc variants that are ubiquitous

(tests failing on macos for not providing C11 ABI)

Andrew Kelley 4a4ea92cf3 remove std.heap.IncrementingAllocator
Use std.heap.FixedBufferAllocator combined with
std.heap.DirectAllocator instead.

std.mem.FixedBufferAllocator is moved to std.heap.FixedBufferAllocator

Andrew Kelley 445b03384a introduce std.heap.ArenaAllocator and std.heap.DirectAllocator
* DirectAllocator does the underlying syscall for every allocation.
 * ArenaAllocator takes another allocator as an argument and
   allocates bytes up front, falling back to DirectAllocator with
   increasingly large allocation sizes, to avoid calling it too often.
   Then the entire arena can be freed at once.

The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.

docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.

The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.

Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.

Fixed a bug in Allocator when you call realloc to grow the allocation.

Andrew Kelley 46aa416c48 std.os and std.io API update
* move std.io.File to std.os.File
 * add `zig fmt` to self hosted compiler
 * introduce std.io.BufferedAtomicFile API
 * introduce std.os.AtomicFile API
 * add `std.os.default_file_mode`
 * change FileMode on posix from being a usize to a u32
 * add std.os.File.mode to return mode of an open file
 * std.os.copyFile copies the mode from the source file instead of
   using the default file mode for the dest file
 * move `std.os.line_sep` to `std.cstr.line_sep`

Andrew Kelley a2bd9f8912 std lib: modify allocator idiom
Before we accepted a nullable allocator for some stuff like
opening files. Now we require an allocator.

Use the mem.FixedBufferAllocator pattern if a bound on the amount
to allocate is known.

This also establishes the pattern that usually an allocator is the
first argument to a function (possibly after "self").

fix docs for std.cstr.addNullByte

self hosted compiler:
 * only build docs when explicitly asked to
 * clean up main
 * stub out zig fmt

Andrew Kelley 31abef172a fix accidentally linking against kernel32 on non windows 2018-02-04 22:13:21 -05:00
Ben Noordhuis 73ee434c8c Use /dev/urandom and sysctl(RANDOM_UUID) on Linux.
Add fallback paths for when the getrandom(2) system call is not
available.  Try /dev/urandom first and sysctl(RANDOM_UUID) second.

The sysctl issues a warning in the system logs with some kernels but
that seems like an acceptable tradeoff for the fallback of a fallback.

Andrew Kelley 2b5e0b66a2 std: fix fn return syntax for zen os 2018-01-29 10:57:27 -05:00
Andrew Kelley 3671582c15 syntax: functions require return type. remove `->`
The purpose of this is:

 * Only one way to do things
 * Changing a function with void return type to return a possible
   error becomes a 1 character change, subtly encouraging
   people to use errors.

See #632

Here are some imperfect sed commands for performing this update:

remove arrow:

```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```

add void:

```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```

Some cleanup may be necessary, but this should do the bulk of the work.
