Andrew Kelley 3173c90f14 macos stack traces: read debug info sections from .o files 2018-08-23 23:08:34 -04:00
Andrew Kelley 5c1ec20c9a MacOS stack traces use the already mmapped executable
...rather than trying to find the executable on the file system.

Also use a more robust PIE offset calculation based on the
available metadata.

And for the last function, use the data that tells the end
rather than assuming 4K.

Also they print in a consistent way with Linux stack traces.

Andrew Kelley 8f96553be8 rename std.debug.ElfStackTrace to std.debug.DebugInfo 2018-08-22 21:35:49 -04:00
Andrew Kelley ea1b21dbdb fix linux
* error.BadFd is not a valid error code. it would always be a bug to
   get this error code.
 * merge error.Io with existing error.InputOutput
 * merge error.PathNotFound with existing error.FileNotFound.
   Not all OS's support both.
 * add os.File.openReadC
 * add error.BadPathName for windows file operations with invalid
   characters
 * add os.toPosixPath to help stack allocate a null terminating byte
 * add some TODOs for other functions to investigate removing the
   allocator requirement
 * optimize some implementations to use the alternate functions when
   a null byte is already available
 * add a missing error.SkipZigTest
 * os.selfExePath uses a non-allocating API
 * os.selfExeDirPath uses a non-allocating API
 * os.path.real uses a non-allocating API
 * add os.path.realAlloc and os.path.realC
 * convert many windows syscalls to use the W versions (See #534)

Andrew Kelley bda5539e9d *WIP* std.os assumes comptime-known max path size
this allows us to remove the requirement of allocators for a lot
of functions

 * std.debug.warn does its printing locked
 * add std.Mutex, however it's currently implemented as a spinlock
 * rename std.event.Group.cancelAll to std.event.Group.deinit and change
   the docs and assumptions.
 * add std.HashMap.clone

breaking syntax change: orelse keyword instead of ?? (#1096)
use the `zig-fmt-optional-default` branch to have zig fmt
automatically do the changes.

2018-06-10 01:13:51 -04:00
Andrew Kelley fc6446702e clean up std.ArrayList
* add `std.debug.assertError`
 * `std.ArrayList` update everything to follow `self` convention
 * rename `std.ArrayList.set` to `std.ArrayList.setOrError`
 * add `std.ArrayList.set` which asserts

Before 1.0.0 we might remove some of this API, because you can use
`toSlice()` for everything, but it's ok to add these functions as
an experiment before then.

Andrew Kelley fcbb7426fa use * for pointer type instead of &
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

to be done - all the std lib used by the behavior tests

Andrew Kelley caefaf781e std.debug: dumpStackTrace & friends use DirectAllocator
this has the downside of failing to print a stack trace
when the system is out of memory (maybe we could add a
FallbackAllocator which tries DirectAllocator and falls
back on the 200KB preallocated buffer).

but for the more common use case when the system is not
out of memory, but the debug info cannot fit in
std.debug.global_allocator, now stack traces will work.

this is the case for the self hosted compiler.

Andrew Kelley 60b2031831 improvements to stack traces
* @panic generates an error return trace
 * printing an error return trace no longer interferes with
   normal stack traces.
 * instead of ignore_frame_count, we look at the return address
   when you call panic, and that's the first stack trace function
   makes stack traces much cleaner - the error return trace
   flows gracefully into the stack trace

Ben Noordhuis ab48934e9c add support for stack traces on macosx
Add basic address->symbol resolution support.  Uses symtab data from the
MachO image, not external dSYM data; that's left as a future exercise.

The net effect is that we can now map addresses to function names but
not much more.  File names and line number data will have to wait until
a future pull request.

Partially fixes #434.

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 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.
