Setting LC_ALL to C helps keep gdb's output consistent ('print' gives us expected output). This fixes#17423. I do not have access to a windows/mac machines to test this. I've only tested it on an x86_64 linux box.
Right now, libuv will **always** be built for the host system (at least when building on OSX) because the information about the cross compiler is never actually passed to GYP. I don't know how anybody has been managing to build cross compilers with this.
Note that, at least on OSX, there is a bug in GYP that will send clang flags to non-clang compilers and it will still attempt to use Xcode's libtool, so this doesn't completely fix the problem of cross-compiling on an OSX host, but it's a start.
Adds a new configure flag, --release-channel, which determines how the version
number should be augmented with a release label, as well as how the distribution
artifacts will be named. This is entirely for use by the build automation.
--release-channel can be either 'source', 'nightly', 'beta', or 'stable'.
Here's a summary of the affect of these values on version number and
artifact naming, respectively:
* source - '0.12.0-pre', 'rust-0.12.0-pre-...'
* nightly - '0.12.0-nightly', 'rust-nightly-...'
* beta - '0.12.0-beta', 'rust-beta-...'
* stable - '0.12.0', 'rust-0.12.0-...'
Per http://discuss.rust-lang.org/t/rfc-impending-changes-to-the-release-process/508/1
This updates our build system to prefer `i686-w64-mingw32` as the 32-bit windows triple instead of `i686-pc-mingw32`. This is an interim step to make the build artifacts consistent until https://github.com/rust-lang/rust/issues/15717 is done.
The Guide isn't 100% perfect, but it's basically complete. It's
certainly better than the tutorial is. Time to start pointing more
people its way.
I also just made it consistent to call all things 'guides' rather than
tutorials.
Fixes#9874. This is the big one.
And two bugs that just go away.
Fixes#14503.

Bugs in pdflatex (#12804) are preventing the guide from landing (https://github.com/rust-lang/rust/pull/16657). This solves the immediate problem by changing the build system to prefer lualatex, xelatex to pdflatex (which is apparently obsolete). Because the xelatex on the snapshot bot seems to completely ignore the `-output-directory` option, I also had to frob the makefiles a bit for that case.
This builds on https://github.com/rust-lang/rust/pull/17109, putting the target triple into the installer name so that we can have both 32-bit and 64-bit.
The resulting installers will be called `rust-0.12.0-pre-x86_64-w64-mingw32.exe`, etc.
Currently `./configure --llvm-root=...` and similar flags will break incremental builds by forcing reconfiguration on every `make`. This happens because `reconfig.mk` incorrectly treats submodules in the `-` (uninitialized) state as requiring reconfiguration, and `./configure` deliberately deinitializes unneeded submodules. The fix is to reconfigure only when submodules are in the `+` state (wrong commit checked out).
The performance hit from these checks is significant, but unoptimized
builds are already incredibly slow. Enabling these checks results in
better test coverage since there are bots doing unoptimized builds, and
the cost is relatively small in the context of an unoptimized build.
This also allows using `JEMALLOC_FLAGS` to override the default
configure flags.
When running `sudo make install`, we only want to run the actual install
as root, the building of the documentation and the distribution folder
should happen as the non-root user.
Related to #13728.
Our implementation of ebml has diverged from the standard in order
to better serve the needs of the compiler, so it doesn't make much
sense to call what we have ebml anyore. Furthermore, our implementation
is pretty crufty, and should eventually be rewritten into a format
that better suits the needs of the compiler. This patch factors out
serialize::ebml into librbml, otherwise known as the Really Bad
Markup Language. This is a stopgap library that shouldn't be used
by end users, and will eventually be replaced by something better.

Not included are two required patches:
* LLVM: segmented stack support for DragonFly [1]
* jemalloc: simple configure patches
[1]: http://reviews.llvm.org/D4705
We'll use this to run a subset of the test suite onto a dedicated
bot.
This puts the grammar tests and the pretty-printer tests under
check-secondary. It leanves the pretty tests under plain `check`
for now, until the new bot is added to take over.
Because check-secondary is not run as part of `make check` there
will be a set of tests that most users never run and are only
checked by bors. I think this will be ok because grammar tests
should rarely regress, and the people regressing such tests
should have the fortitude to deal with it.
The alignment of the line continuation backslashes is rather inconsistent. These commits solve that by removing the extra whitespace and adding a space where there previously was none. An alternative solution would be to fix the alignment.
Three small changes:
1. Re-organize headers in the Strings guide so they show up correctly.
2. build the strings guide with the other docs
3. include the strings guide in the list of guides
Add libunicode; move unicode functions from core
- created new crate, libunicode, below libstd
- split `Char` trait into `Char` (libcore) and `UnicodeChar` (libunicode)
- Unicode-aware functions now live in libunicode
- `is_alphabetic`, `is_XID_start`, `is_XID_continue`, `is_lowercase`,
`is_uppercase`, `is_whitespace`, `is_alphanumeric`, `is_control`, `is_digit`,
`to_uppercase`, `to_lowercase`
- added `width` method in UnicodeChar trait
- determines printed width of character in columns, or None if it is a non-NULL control character
- takes a boolean argument indicating whether the present context is CJK or not (characters with 'A'mbiguous widths are double-wide in CJK contexts, single-wide otherwise)
- split `StrSlice` into `StrSlice` (libcore) and `UnicodeStrSlice` (libunicode)
- functionality formerly in `StrSlice` that relied upon Unicode functionality from `Char` is now in `UnicodeStrSlice`
- `words`, `is_whitespace`, `is_alphanumeric`, `trim`, `trim_left`, `trim_right`
- also moved `Words` type alias into libunicode because `words` method is in `UnicodeStrSlice`
- unified Unicode tables from libcollections, libcore, and libregex into libunicode
- updated `unicode.py` in `src/etc` to generate aforementioned tables
- generated new tables based on latest Unicode data
- added `UnicodeChar` and `UnicodeStrSlice` traits to prelude
- libunicode is now the collection point for the `std::char` module, combining the libunicode functionality with the `Char` functionality from libcore
- thus, moved doc comment for `char` from `core::char` to `unicode::char`
- libcollections remains the collection point for `std::str`
The Unicode-aware functions that previously lived in the `Char` and `StrSlice` traits are no longer available to programs that only use libcore. To regain use of these methods, include the libunicode crate and `use` the `UnicodeChar` and/or `UnicodeStrSlice` traits:
extern crate unicode;
use unicode::UnicodeChar;
use unicode::UnicodeStrSlice;
use unicode::Words; // if you want to use the words() method
NOTE: this does *not* impact programs that use libstd, since UnicodeChar and UnicodeStrSlice have been added to the prelude.

- unicode tests live in coretest crate
- libcollections str tests need UnicodeChar trait.
- libregex perlw tests were checking a char in the Alphabetic category,
\x2161. Confirmed perl 5.18 considers this a \w character. Changed to
\x2961, which is not \w as the test expects.
This commit disables rustc's emission of rpath attributes into dynamic libraries
and executables by default. The functionality is still preserved, but it must
now be manually enabled via a `-C rpath` flag.
This involved a few changes to the local build system:
* --disable-rpath is now the default configure option
* Makefiles now prefer our own LD_LIBRARY_PATH over the user's LD_LIBRARY_PATH
in order to support building rust with rust already installed.
* The compiletest program was taught to correctly pass through the aux dir as a
component of LD_LIBRARY_PATH in more situations.
The major impact of this change is that neither rustdoc nor rustc will work
out-of-the-box in all situations because they are dynamically linked. It must be
arranged to ensure that the libraries of a rust installation are part of the
LD_LIBRARY_PATH. The default installation paths for all platforms ensure this,
but if an installation is in a nonstandard location, then configuration may be
necessary.
Additionally, for all developers of rustc, it will no longer be possible to run
$target/stageN/bin/rustc out-of-the-box. The old behavior can be regained
through the `--enable-rpath` option to the configure script.
This change brings linux/mac installations in line with windows installations
where rpath is not possible.

The compiler will no longer insert a hash or version into a filename by default.
Instead, all output is simply based off the crate name being compiled. For
example, a crate name of `foo` would produce the following outputs:
* bin => foo
* rlib => libfoo.rlib
* dylib => libfoo.{so,dylib} or foo.dll
* staticlib => libfoo.a
The old behavior has been moved behind a new codegen flag,
`-C extra-filename=<hash>`. For example, with the "extra filename" of `bar` and
a crate name of `foo`, the following outputs would be generated:
* bin => foo (same old behavior)
* rlib => libfoobar.rlib
* dylib => libfoobar.{so,dylib} or foobar.dll
* staticlib => libfoobar.a
The makefiles have been altered to pass a hash by default to invocations of
`rustc` so all installed rust libraries will have a hash in their filename. This
is done because the standard libraries are intended to be installed into
privileged directories such as /usr/local. Additionally, it involves very few
build system changes!

This makes the `in-header`, `markdown-before-content`, and `markdown-after-content` options available to `rustdoc` when generating documentation for any crate.
Before, these options were only available when creating documentation *from* markdown. Now, they are available when generating documentation from source.
This also updates the `rustdoc -h` output to reflect these changes. It does not update the `man rustdoc` page, nor does it update the documentation in [the `rustdoc` manual](http://doc.rust-lang.org/rustdoc.html).
Libcore's test infrastructure is complicated by the fact that many lang
items are defined in the crate. The current approach (realcore/realstd
imports) is hacky and hard to work with (tests inside of core::cmp
haven't been run for months!).
Moving tests to a separate crate does mean that they can only test the
public API of libcore, but I don't feel that that is too much of an
issue. The only tests that I had to get rid of were some checking the
various numeric formatters, but those are also exercised through normal
format! calls in other tests.
In line with what @brson, @cmr, @nikomatsakis and I discussed this morning, my
redux of the tutorial will be implemented as the Guide. This way, I can work in
small iterations, rather than dropping a huge PR, which is hard to review. In
addition, the community can observe my work as I'm doing it.
This adds a note in line with [this comment][reddit] that clarifies the state
of the tutorial, and the community's involvement with it.

This change was spliced out of #14832 to consist of just the fixes to running
tests without an rpath setting embedded in executables.
It seems in one of rebases I’ve resolved conflicts wrong and left one redundant line, it is absent in current master and it might cause compilation failure by copying file into itself.
Rust no longer has support for JIT compilation, so it doesn't currently
require a PaX MPROTECT exception. The extended attributes are preferred
over modifying the binaries so it's not actually going to work on most
systems like this anyway.
If JIT compilation ends up being supported again, it should handle this
by *always* applying the exception via an extended attribute without
performing auto-detection of PaX on the host. The `paxctl` tool is only
necessary with the older method involving modifying the ELF binary.
