One, switch all your -** code to a language that provides automatic garbage collection, for -** example Java. This is a fine idea and I recommend you do it wherever -** it's feasible. Two, change your routines to use a calling convention -** that prevents people from writing multiple-call expressions like that. -** The resulting code will be somewhat clumsy-looking, but it will work -** just fine. -** -** This package uses a third method, which I haven't seen used anywhere -** before.

Here's the above example using this convention: -** -** d = bi_sqrt( bi_add( -** bi_multiply( bi_copy( x ), bi_copy( x ) ), -** bi_multiply( bi_copy( y ), bi_copy( y ) ) ) ); -** bi_free( x ); -** bi_free( y ); -** -** Or, since the package contains a square routine, you could just write: -** -** d = bi_sqrt( bi_add( bi_square( x ), bi_square( y ) ) ); -** -** This time the named values are only being used once, so you don't -** have to copy and free them. -** -** This really works, however you do have to be very careful when writing -** your code. If you leave out a bi_copy() and use a value more than once, -** you'll get a runtime error about "zero refs" and a SIGFPE.

They +begin by replacing all bound regions (on both sides) with fresh region +inference variables. Therefore, both functions are converted to types +that contain only free regions. We can then compute the LUB/GLB in a +straightforward way, as described in `combine.rs`. This results in an +interim type T. The algorithms then examine the regions that appear +in T and try to, in some cases, replace them with bound regions to +yield the final result. + +To decide whether to replace a region `R` that appears in `T` with a +bound region, the algorithms make use of two bits of information. +First is a set `V` that contains all region variables created as part +of the LUB/GLB computation. `V` will contain the region variables +created to replace the bound regions in the input types, but it also +contains 'intermediate' variables created to represent the LUB/GLB of +individual regions. Basically, when asked to compute the LUB/GLB of a +region variable with another region, the inferencer cannot oblige +immediately since the valuese of that variables are not known. +Therefore, it creates a new variable that is related to the two +regions. For example, the LUB of two variables `$x` and `$y` is a +fresh variable `$z` that is constrained such that `$x <= $z` and `$y +<= $z`. So `V` will contain these intermediate variables as well. + +The other important factor in deciding how to replace a region in T is +the function `Tainted($r)` which, for a region variable, identifies +all regions that the region variable is related to in some way +(`Tainted()` made an appearance in the subtype computation as well). + ### LUB The LUB algorithm proceeds in three steps: @@ -345,47 +400,28 @@ The LUB algorithm proceeds in three steps: inference variables. 2.

Map the regions appearing in `F` using the procedure described below. - -For each region `R` that appears in `F`, we may need to replace it -with a bound region. Let `V` be the set of fresh variables created as -part of the LUB procedure (either in step 1 or step 2). You may be -wondering how variables can be created in step 2. The answer is that -when we are asked to compute the LUB or GLB of two region variables, -we do so by producing a new region variable that is related to those -two variables. i.e., The LUB of two variables `$x` and `$y` is a -fresh variable `$z` that is constrained such that `$x <= $z` and `$y -<= $z`. - -To decide how to replace a region `R`, we must examine `Tainted(R)`. -This function searches through the constraints which were generated -when computing the bounds of all the argument and return types and -produces a list of all regions to which `R` is related, directly or -indirectly. - -If `R` is not in `V` or `Tainted(R)` contains any region that is not -in `V`, then `R` is not replaced (that is, `R` is mapped to itself). -Otherwise, if `Tainted(R)` is a subset of `V`, then we select the -earliest variable in `Tainted(R)` that originates from the left-hand -side and replace `R` with a bound version of that variable. - -So, let's work through the simplest example: `fn(&A)` and `fn(&a)`. -In this case, `&a` will be replaced with `$a` (the $ indicates an -inference variable) which will be linked to the free region `&A`, and -hence `V = { $a }` and `Tainted($a) = { &A }`.

I will try to write up something +more convincing in the future. + +#### Where are the algorithms wrong? + +- The pre-replacement computation can fail even though using a + bound-region would have succeeded. +- We will compute GLB(fn(fn($a)), fn(fn($b))) as fn($c) where $c is the + GLB of $a and $b.

We've seen some of Rust's pointer sigils (`@`, -`~`, and `&`) float by in a few examples, and we aren't going to get -much further without explaining them. Rust has a very particular -approach to memory management that plays a significant role in shaping -the subjective experience of programming in the -language. Understanding the memory landscape will illuminate several -of Rust's unique features as we encounter them. - -Rust has three competing goals that inform its view of memory: - -* Memory safety: Memory that the Rust language can observe must be - guaranteed to be valid. Under normal circumstances, it must be - impossible for Rust to trigger a segmentation fault or leak memory. -* Performance: High-performance low-level code must be able to use - a number of different allocation strategies. Tracing garbage collection must be - optional and, if it is not desired, memory safety must not be compromised. - Less performance-critical, high-level code should be able to employ a single, - garbage-collection-based, heap allocation strategy. -* Concurrency: Rust code must be free of in-memory data races. (Note that other - types of races are still possible.) - -## How performance considerations influence the memory model - -Most languages that offer strong memory safety guarantees rely on a -garbage-collected heap to manage all of the objects. This approach is -straightforward both in concept and in implementation, but has -significant costs. Languages that follow this path tend to -aggressively pursue ways to ameliorate allocation costs (think the -Java Virtual Machine). Rust supports this strategy with _managed -boxes_: memory allocated on the heap whose lifetime is managed -by the garbage collector. - -By comparison, languages like C++ offer very precise control over -where objects are allocated. In particular, it is common to allocate them -directly on the stack, avoiding expensive heap allocation. In Rust -this is possible as well, and the compiler uses a [clever _pointer -lifetime analysis_][borrow] to ensure that no variable can refer to stack -objects after they are destroyed. - -[borrow]: tutorial-borrowed-ptr.html - -## How concurrency considerations influence the memory model - -Memory safety in a concurrent environment involves avoiding race -conditions between two threads of execution accessing the same -memory. Even high-level languages often require programmers to make -correct use of locking to ensure that a program is free of races. - -Rust starts from the position that memory cannot be shared between -tasks. Experience in other languages has proven that isolating each -task's heap from the others is a reliable strategy and one that is -easy for programmers to reason about. Heap isolation has the -additional benefit that garbage collection must only be done -per-heap. Rust never "stops the world" to reclaim memory. - -Complete isolation of heaps between tasks would, however, mean that -any data transferred between tasks must be copied. While this is a -fine and useful way to implement communication between tasks, it is -also very inefficient for large data structures. To reduce the amount -of copying, Rust also uses a global _exchange heap_. Objects allocated -in the exchange heap have _ownership semantics_, meaning that there is -only a single variable that refers to them. For this reason, they are -referred to as _owned boxes_. All tasks may allocate objects on the -exchange heap, then transfer ownership of those objects to other -tasks, avoiding expensive copies. - # Boxes and pointers Many modern languages have a so-called "uniform representation" for From 329a57882f813a0d77500aa499426882e9ef3dbb Mon Sep 17 00:00:00 2001 From: Tim Chevalier Date: Thu, 10 Jan 2013 15:15:24 -0800 Subject: [PATCH 183/264] Add xfailed test for #3973 --- src/test/compile-fail/issue-3973.rs | 31 +++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 src/test/compile-fail/issue-3973.rs diff --git a/src/test/compile-fail/issue-3973.rs b/src/test/compile-fail/issue-3973.rs new file mode 100644 index 0000000000000..6c977840c2257 --- /dev/null +++ b/src/test/compile-fail/issue-3973.rs @@ -0,0 +1,31 @@ +// Copyright 2012 The Rust Project Developers.
