Additional Definitions. 14 | 15 | As used herein, "this License" refers to version 3 of the GNU Lesser 16 | General Public License, and the "GNU GPL" refers to version 3 of the GNU 17 | General Public License. 18 | 19 | "The Library" refers to a covered work governed by this License, 20 | other than an Application or a Combined Work as defined below. 21 | 22 | An "Application" is any work that makes use of an interface provided 23 | by the Library, but which is not otherwise based on the Library. 24 | Defining a subclass of a class defined by the Library is deemed a mode 25 | of using an interface provided by the Library. 26 | 27 | A "Combined Work" is a work produced by combining or linking an 28 | Application with the Library. The particular version of the Library 29 | with which the Combined Work was made is also called the "Linked 30 | Version". 31 | 32 | The "Minimal Corresponding Source" for a Combined Work means the 33 | Corresponding Source for the Combined Work, excluding any source code 34 | for portions of the Combined Work that, considered in isolation, are 35 | based on the Application, and not on the Linked Version. 36 | 37 | The "Corresponding Application Code" for a Combined Work means the 38 | object code and/or source code for the Application, including any data 39 | and utility programs needed for reproducing the Combined Work from the 40 | Application, but excluding the System Libraries of the Combined Work. 41 | 42 | 1. Exception to Section 3 of the GNU GPL. 43 | 44 | You may convey a covered work under sections 3 and 4 of this License 45 | without being bound by section 3 of the GNU GPL. 46 | 47 | 2. Conveying Modified Versions. 48 | 49 | If you modify a copy of the Library, and, in your modifications, a 50 | facility refers to a function or data to be supplied by an Application 51 | that uses the facility (other than as an argument passed when the 52 | facility is invoked), then you may convey a copy of the modified 53 | version: 54 | 55 | a) under this License, provided that you make a good faith effort to 56 | ensure that, in the event an Application does not supply the 57 | function or data, the facility still operates, and performs 58 | whatever part of its purpose remains meaningful, or 59 | 60 | b) under the GNU GPL, with none of the additional permissions of 61 | this License applicable to that copy. 62 | 63 | 3. Object Code Incorporating Material from Library Header Files. 64 | 65 | The object code form of an Application may incorporate material from 66 | a header file that is part of the Library. You may convey such object 67 | code under terms of your choice, provided that, if the incorporated 68 | material is not limited to numerical parameters, data structure 69 | layouts and accessors, or small macros, inline functions and templates 70 | (ten or fewer lines in length), you do both of the following: 71 | 72 | a) Give prominent notice with each copy of the object code that the 73 | Library is used in it and that the Library and its use are 74 | covered by this License. 75 | 76 | b) Accompany the object code with a copy of the GNU GPL and this license 77 | document. 78 | 79 | 4. Combined Works. 80 | 81 | You may convey a Combined Work under terms of your choice that, 82 | taken together, effectively do not restrict modification of the 83 | portions of the Library contained in the Combined Work and reverse 84 | engineering for debugging such modifications, if you also do each of 85 | the following: 86 | 87 | a) Give prominent notice with each copy of the Combined Work that 88 | the Library is used in it and that the Library and its use are 89 | covered by this License. 90 | 91 | b) Accompany the Combined Work with a copy of the GNU GPL and this license 92 | document. 93 | 94 | c) For a Combined Work that displays copyright notices during 95 | execution, include the copyright notice for the Library among 96 | these notices, as well as a reference directing the user to the 97 | copies of the GNU GPL and this license document. 98 | 99 | d) Do one of the following: 100 | 101 | 0) Convey the Minimal Corresponding Source under the terms of this 102 | License, and the Corresponding Application Code in a form 103 | suitable for, and under terms that permit, the user to 104 | recombine or relink the Application with a modified version of 105 | the Linked Version to produce a modified Combined Work, in the 106 | manner specified by section 6 of the GNU GPL for conveying 107 | Corresponding Source. 108 | 109 | 1) Use a suitable shared library mechanism for linking with the 110 | Library. A suitable mechanism is one that (a) uses at run time 111 | a copy of the Library already present on the user's computer 112 | system, and (b) will operate properly with a modified version 113 | of the Library that is interface-compatible with the Linked 114 | Version. 115 | 116 | e) Provide Installation Information, but only if you would otherwise 117 | be required to provide such information under section 6 of the 118 | GNU GPL, and only to the extent that such information is 119 | necessary to install and execute a modified version of the 120 | Combined Work produced by recombining or relinking the 121 | Application with a modified version of the Linked Version. (If 122 | you use option 4d0, the Installation Information must accompany 123 | the Minimal Corresponding Source and Corresponding Application 124 | Code. If you use option 4d1, you must provide the Installation 125 | Information in the manner specified by section 6 of the GNU GPL 126 | for conveying Corresponding Source.) 127 | 128 | 5. Combined Libraries. 129 | 130 | You may place library facilities that are a work based on the 131 | Library side by side in a single library together with other library 132 | facilities that are not Applications and are not covered by this 133 | License, and convey such a combined library under terms of your 134 | choice, if you do both of the following: 135 | 136 | a) Accompany the combined library with a copy of the same work based 137 | on the Library, uncombined with any other library facilities, 138 | conveyed under the terms of this License. 139 | 140 | b) Give prominent notice with the combined library that part of it 141 | is a work based on the Library, and explaining where to find the 142 | accompanying uncombined form of the same work. 143 | 144 | 6. Revised Versions of the GNU Lesser General Public License. 145 | 146 | The Free Software Foundation may publish revised and/or new versions 147 | of the GNU Lesser General Public License from time to time. Such new 148 | versions will be similar in spirit to the present version, but may 149 | differ in detail to address new problems or concerns. 150 | 151 | Each version is given a distinguishing version number. If the 152 | Library as you received it specifies that a certain numbered version 153 | of the GNU Lesser General Public License "or any later version" 154 | applies to it, you have the option of following the terms and 155 | conditions either of that published version or of any later version 156 | published by the Free Software Foundation. If the Library as you 157 | received it does not specify a version number of the GNU Lesser 158 | General Public License, you may choose any version of the GNU Lesser 159 | General Public License ever published by the Free Software Foundation. 160 | 161 | If the Library as you received it specifies that a proxy can decide 162 | whether future versions of the GNU Lesser General Public License shall 163 | apply, that proxy's public statement of acceptance of any version is 164 | permanent authorization for you to choose that version for the 165 | Library. 166 | 167 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # This Gem is unsafe [![Build Status](https://travis-ci.org/bascht/unsafe.svg?branch=master)](https://travis-ci.org/bascht/unsafe) 2 | 3 | Want to try Rust [unsafe{}](https://doc.rust-lang.org/book/unsafe.html)? 4 | Still stuck with Ruby? 5 | 6 | This is for you. 7 | 8 | ## All the goodness in one Gem 9 | 10 | * No Garbage collector 11 | * Nullpointers 12 | * Uncertainty. 13 | 14 | ### Usage 15 | 16 | ```ruby 17 | #!/usr/bin/env ruby 18 | # -- encoding: utf-8 -- 19 | 20 | require 'unsafe/unsafe' 21 | 22 | CHANCE_OF_DOOM=0.5 23 | 24 | unsafe { 25 | (1..10).each do |i| 26 | puts "I'm fine." 27 | sleep 1 28 | end 29 | } 30 | ``` 31 | Voila: 32 | 33 | ```shell 34 | $ unsafe 35 | I'm fine. 36 | I'm fine. 37 | I'm fine. 38 | I'm fine. 39 | I'm fine. 40 | I'm fine. 41 | /home/bascht/.rvm/gems/ruby-2.2.1/gems/unsafe-0.1-x86_64-linux/lib/unsafe/unsafe.rb:10: [BUG] Segmentation fault a 42 | t 0x007f3e1ccaf805 43 | ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-linux] 44 | 45 | -- Control frame information ----------------------------------------------- 46 | c:0003 p:---- s:0007 e:000006 CFUNC :fire 47 | c:0002 p:0044 s:0004 e:000003 BLOCK /home/bascht/.rvm/gems/ruby-2.2.1/gems/unsafe-0.1-x86_64-linux/lib/unsafe/uns 48 | afe.rb:10 [FINISH] 49 | c:0001 p:---- s:0002 e:000001 TOP [FINISH] 50 | 51 | -- Ruby level backtrace information ---------------------------------------- 52 | /home/bascht/.rvm/gems/ruby-2.2.1/gems/unsafe-0.1-x86_64-linux/lib/unsafe/unsafe.rb:10:in `block in unsafe' 53 | /home/bascht/.rvm/gems/ruby-2.2.1/gems/unsafe-0.1-x86_64-linux/lib/unsafe/unsafe.rb:10:in `fire' 54 | 55 | -- Machine register context ------------------------------------------------ 56 | RIP: 0x00007f3e1ccaf7c0 RBP: 0x0000000000000000 RSP: 0x00007f3e1cbac368 57 | RAX: 0x0000000000000000 RBX: 0x00000000011d45b0 RCX: 0x00007f3e1cbae038 58 | RDX: 0x00007f3e1ccaf7c0 RDI: 0x000000000120c1e0 RSI: 0x000000000120c1e0 59 | R8: 0x00007f3e24e9f240 R9: 0x000000000120c1e0 R10: 0x0000000000000000 60 | R11: 0x000000000120c190 R12: 0x0000000000000003 R13: 0x00000000012e0830 61 | R14: 0x00007f3e1ccadf70 R15: 0x0000000001239ee0 EFL: 0x0000000000010246 62 | 63 | -- C level backtrace information ------------------------------------------- 64 | /home/bascht/.rvm/rubies/ruby-2.2.1/lib/libruby.so.2.2(rb_vm_bugreport+0x4ea) [0x7f3e24f6cdba] vm_dump.c:693 65 | /home/bascht/.rvm/rubies/ruby-2.2.1/lib/libruby.so.2.2(rb_bug_context+0xcb) [0x7f3e24e065eb] error.c:425 66 | /home/bascht/.rvm/rubies/ruby-2.2.1/lib/libruby.so.2.2(sigsegv+0x3e) [0x7f3e24ee367e] signal.c:879 67 | /lib64/libpthread.so.0 [0x7f3e24b7e430] 68 | 69 | ``` 70 | -------------------------------------------------------------------------------- /Rakefile: -------------------------------------------------------------------------------- 1 | require 'rake' 2 | require 'rake/testtask' 3 | 4 | Rake::TestTask.new do |t| 5 | t.test_files = Dir.glob('test/test_*.rb') 6 | end 7 | 8 | task(default: :test) 9 | -------------------------------------------------------------------------------- /ext/lose_kanone/extconf.rb: -------------------------------------------------------------------------------- 1 | require 'mkmf' 2 | create_makefile('lose_kanone/lose_kanone') 3 | -------------------------------------------------------------------------------- /ext/lose_kanone/lose_kanone.c: -------------------------------------------------------------------------------- 1 | #include 2 | 3 | static void fire(VALUE klass) 4 | { 5 | char *this = "is the end";
