Bison 3.4.2 released [stable]

Filed under
GNU

Bison 3.4.2 is a bug fix release of the 3.4 series.  It fixes a number of 
hard-to-find bugs, mostly discovered by fuzzing. 
In Bison 3.4 a particular focus was put on improving the diagnostics, which 
are now colored by default, and accurate with multibyte input.  Their format 
was also changed, and is now similar to GCC 9's diagnostics. 
Users of the default backend (yacc.c) can use the new %define variable 
api.header.include to avoid duplicating the content of the generated header 
in the generated parser.  There are two new examples installed, including a 
reentrant calculator which supports recursive calls to the parser and 
Flex-generated scanner. 
See below for more details. 
================================================================== 
Bison is a general-purpose parser generator that converts an annotated 
context-free grammar into a deterministic LR or generalized LR (GLR) parser 
employing LALR(1) parser tables.  Bison can also generate IELR(1) or 
canonical LR(1) parser tables.  Once you are proficient with Bison, you can 
use it to develop a wide range of language parsers, from those used in 
simple desk calculators to complex programming languages. 
Bison is upward compatible with Yacc: all properly-written Yacc grammars 
work with Bison with no change.  Anyone familiar with Yacc should be able to 
use Bison with little trouble.  You need to be fluent in C, C++ or Java 
programming in order to use Bison.

NEWS 
* Noteworthy changes in release 3.4.2 (2019-09-08) [stable]

** Bug fixes

  In some cases, when warnings are disabled, bison could emit tons of white
  spaces as diagnostics.

  When running out of memory, bison could crash (found by fuzzing).

  When defining twice the EOF token, bison would crash.

  New warnings from recent compilers have been addressed in the generated
  parsers (yacc.c, glr.c, glr.cc).

  When lone carriage-return characters appeared in the input file,
  diagnostics could hang forever.

* Noteworthy changes in release 3.4.1 (2019-05-22) [stable]

** Bug fixes

  Portability fixes.

* Noteworthy changes in release 3.4 (2019-05-19) [stable]

** Deprecated features

  The %pure-parser directive is deprecated in favor of '%define api.pure'
  since Bison 2.3b (2008-05-27), but no warning was issued; there is one
  now.  Note that since Bison 2.7 you are strongly encouraged to use
  '%define api.pure full' instead of '%define api.pure'.

** New features

*** Colored diagnostics

  As an experimental feature, diagnostics are now colored, controlled by the
  new options --color and --style.

  To use them, install the libtextstyle library before configuring Bison.
  It is available from

    https://alpha.gnu.org/gnu/gettext/

  for instance

    https://alpha.gnu.org/gnu/gettext/libtextstyle-0.8.tar.gz

  The option --color supports the following arguments:
    - always, yes: Enable colors.
    - never, no: Disable colors.
    - auto, tty (default): Enable colors if the output device is a tty.

  To customize the styles, create a CSS file similar to

    /* bison-bw.css */
    .warning   { }
    .error     { font-weight: 800; text-decoration: underline; }
    .note      { }

  then invoke bison with --style=bison-bw.css, or set the BISON_STYLE
  environment variable to "bison-bw.css".

*** Disabling output

  When given -fsyntax-only, the diagnostics are reported, but no output is
  generated.

  The name of this option is somewhat misleading as bison does more than
  just checking the syntax: every stage is run (including checking for
  conflicts for instance), except the generation of the output files.

*** Include the generated header (yacc.c)

  Before, when --defines is used, bison generated a header, and pasted an
  exact copy of it into the generated parser implementation file.  If the
  header name is not "y.tab.h", it is now #included instead of being
  duplicated.

  To use an '#include' even if the header name is "y.tab.h" (which is what
  happens with --yacc, or when using the Autotools' ylwrap), define
  api.header.include to the exact argument to pass to #include.  For
  instance:

    %define api.header.include {"parse.h"}

  or

    %define api.header.include {}

*** api.location.type is now supported in C (yacc.c, glr.c)

  The %define variable api.location.type defines the name of the type to use
  for locations.  When defined, Bison no longer defines YYLTYPE.

  This can be used in programs with several parsers to factor their
  definition of locations: let one of them generate them, and the others
  just use them.

** Changes

*** Graphviz output

  In conformance with the recommendations of the Graphviz team, if %require
  "3.4" (or better) is specified, the option --graph generates a *.gv file
  by default, instead of *.dot.

*** Diagnostics overhaul

  Column numbers were wrong with multibyte characters, which would also
  result in skewed diagnostics with carets.  Beside, because we were
  indenting the quoted source with a single space, lines with tab characters
  were incorrectly underlined.

  To address these issues, and to be clearer, Bison now issues diagnostics
  as GCC9 does.  For instance it used to display (there's a tab before the
  opening brace):

    foo.y:3.37-38: error: $2 of ‘expr’ has no declared type
     expr: expr '+' "number"        { $$ = $1 + $2; }
                                         ^~
  It now reports

    foo.y:3.37-38: error: $2 of ‘expr’ has no declared type
        3 | expr: expr '+' "number" { $$ = $1 + $2; }
          |                                     ^~

  Other constructs now also have better locations, resulting in more precise
  diagnostics.

*** Fix-it hints for %empty

  Running Bison with -Wempty-rules and --update will remove incorrect %empty
  annotations, and add the missing ones.

*** Generated reports

  The format of the reports (parse.output) was improved for readability.

*** Better support for --no-line.

  When --no-line is used, the generated files are now cleaner: no lines are
  generated instead of empty lines.  Together with using api.header.include,
  that should help people saving the generated files into version control
  systems get smaller diffs.

** Documentation

  A new example in C shows an simple infix calculator with a hand-written
  scanner (examples/c/calc).

  A new example in C shows a reentrant parser (capable of recursive calls)
  built with Flex and Bison (examples/c/reccalc).

  There is a new section about the history of Yaccs and Bison.

** Bug fixes

  A few obscure bugs were fixed, including the second oldest (known) bug in
  Bison: it was there when Bison was entered in the RCS version control
  system, in December 1987.  See the NEWS of Bison 3.3 for the previous
  oldest bug.

Stallman Under Fire for Views on Epstein

  • Famed MIT Scientist Defends Epstein: Victims Were ‘Entirely Willing’

    While MIT engages in damage control following revelations the university’s Media Lab accepted millions of dollars in funding from Jeffrey Epstein, a renowned computer scientist at the university has fanned the flames by apparently going out of his way to defend the accused sex trafficker — and child pornography in general.

    Richard Stallman has been hailed as one of the most influential computer scientists around today and honored with a slew of awards and honorary doctorates, but his eminence in the academic computer science community came into question Friday afternoon when purportedly leaked email excerpts showed him suggesting one of Epstein’s alleged victims was “entirely willing.”

  • Prominent computer scientist at MIT argues definition of rape in defending money from dead sex offender

    Richard Stallman, founder of Cambridge's Free Software Foundation and a visiting scientist at MIT, argues that Jeffrey Epstein's victims were likely "entirely willing" and to stop besmirching the good name of deceased MIT AI guru Marvin Minsky just because he might have "had sex with one of Epstein’s harem."

    Vice reports Stallman made his comments on an MIT mailing list on which he objected to a protest being planned for next week over MIT's ties to the convicted sex offender long after his conviction.

  • Free software icon Richard Stallman has some moronic thoughts about pedophilia

    The world of academia is in turmoil over the shock discovery that disgraced financier Jeffrey Epstein funded several several prestigious science and technology research labs, including MIT’s Media Lab, long after his 2008 conviction for sex crimes involving children.

    For the late Epstein, his generous donations served to whitewash his tainted reputation. They were part of a well-sculpted PR effort that also included paid-for puff pieces in publications like Forbes and HuffPost, which emphasised his philanthropy, while conveniently ignoring his crimes.

  • Famed Computer Scientist Richard Stallman Described Epstein Victims As 'Entirely Willing'

    Richard Stallman, the computer scientist best known for his role in the free software movement, has joined the list of MIT men going out of their way to defend the university’s relationships with convicted sex offender Jeffrey Epstein.

    Selam Jie Gano, an MIT alum, posted on Medium about an email thread in which Stallman argued that the late Marvin Minsky—an AI pioneer accused of assaulting one of Epstein's victims, Virginia Giuffre—had not actually assaulted anyone.

  • MIT Community Horrified by Famed Researcher’s Epstein Outburst

    Since the July arrest of Jeffrey Epstein on charges of sex trafficking, a number of huge names in the world of tech — from Bill Gates to Elon Musk — have attempted to defend or deny any inkling of a relationship with the financier.

    But one prominent computer scientist is seemingly going out of his way to insert himself into the scandal: MIT Visiting Scientist Richard Stallman.

    MIT accepted millions of dollars in funding from Epstein, prompting one student group to organize a protest calling for the resignation of any senior MIT administrators who knew about the donations.

  • Kernel Lockdown Feature Will Try To Land For Linux 5.4

    After going through 40+ rounds of revisions and review, the Linux kernel "LOCKDOWN" feature might finally make it into the Linux 5.4 mainline kernel.

    While not yet acted upon by Linus Torvalds with the Linux 5.4 merge window not opening until next week, James Morris has submitted a pull request introducing the kernel lockdown mode for Linux 5.4.

  • Linux 5.4 Pull Requests Begin With AMD EPYC Rome EDAC Support, 64-Bit ARM Updates

    Linux 5.3 isn't being released until this weekend after being delayed by one week, but already there have been a few early pull requests submitted for the to-be-opened Linux 5.4 merge window.

    The early Linux 5.4 material submitted so far includes:

    ARM64 updates come in with a growing number of contributors to this 64-bit ARM architecture code. This time around there is support for 52-bit virtual addressing, early random number generator (RNG) seeding by the bootloader, improved robustness of SMP booting, support for the NXP i.MX8 DDR PMU, and various other fixes and improvements.

  • Linux 5.4 Bringing Support For Lenovo's "PrivacyGuard" On Newer ThinkPads

    Newer high-end Lenovo ThinkPad laptops feature an option called "PrivacyGuard" for restricting the usable vertical and horizontal viewing angles of the LCD display, similar to what has been achievable previously using film covers and the like. With Linux 5.4 this feature will be supported by the kernel if concerned about others looking over your shoulders at your screen, etc.

    Lenovo PrivacyGuard allows restricting the usable vertical/horizontal angles of the laptop's LCD panel so that ideally no one else but the user can view the screen contents. Unlike film covers or other practices, PrivacyGuard can be easily enabled/disabled depending upon your location. PrivacyGuard hasn't worked under Linux up to this point but is coming now with Linux 5.4.

  • Updated high-DPI support for Qt 5.14
    Hi all,
    
    We’ve recently merged several patches which improves Qt’s high-DPI support. The changes include:
    
    * Support for fractional device pixel ratios (e.g. Windows 150%)
    * Support per-screen DPI in more places like QStyle
    * Cleanup of configuration API and options.
    
    These fixes applies mostly to the AA_EnableHighDpiScaling type of high-DPI support where 
    the device independent coordinate system is set up by QtGui. Relevant platforms include Windows,
    X11, and Android. The new code and and config options are cross-platform though; it should be
    possible to develop and test on any platform (as long as you are not working on platform plugins).
    
    
  • Qt 5.14 Is Bringing Significantly Better HiDPI Support

    Besides KDE seeing its own HiDPI improvements like fractional scaling on Wayland recently landing, the Qt5 tool-kit is seeing more HiDPI improvements on its end too.

    With Qt 5.14 that is slated to be released before year's end there will be better HiDPI support for dealing with today's modern high pixel density displays. Some of the Qt 5.14 HiDPI improvements include support for fractional device pixel ratios, supporting per-screen DPIs more throughout the tool-kit, configuration API clean-ups, platform plug-in additions, an API for setting the rounding policy for the scaling factor, and expanding the supported environment variables for testing the functionality.

  • Reactive Foundation tackles next phase of software architecture

    “With the rise of cloud-native computing and modern application development practices, reactive programming addresses challenges with message streams and will be critical to adoption,” said Michael Dolan, VP of strategic programs at the Linux Foundation. “With the Reactive Foundation, the industry now has a neutral home for supporting the open source projects enabling reactive programming.”

    [...]

    RSocket builds on reactive streams to prevent outages and is designed to support microservices-based and cloud-native applications as a high-performance replacement of traditional HTTP. It enables long-lived streams on different transport connections, which is useful for mobile to server communication. The foundation will also seeks to expand the open-source community around RSocket and reactive programming.

    “After more than a decade of innovations, the reactive ecosystem is making it into mainstream adoption with Project Reactor, Spring Boot and the Spring Framework accelerating its adoption,” said Stephane Maldini, project reactor lLead at Pivotal. “Together, we can build hyper efficient, scalable distributed systems by rethinking the way we design them and by using the right protocol to coordinate them.”

    Some sad news to share this Friday evening, as Unknown Worlds Entertainment have announced they're calling it a day for the Linux version of Natural Selection 2.

    Unlike what happened with Rust, they're not offering refunds to previous buyers.

  • Story-driven tactical RPG with time manipulation mechanics 'Iron Danger' should come to Linux

    Here's some fun news, Iron Danger from Action Squad Studios sounds interesting and it's trying to set itself apart from the many turn-based tactical RPGs out there.

    With the fate of the entire world apparently in your hands you will deal with cosmic magic, monsters and colossal war machines in an attempt to save it. I like games that combine elements from different time periods, so you're dealing with both magic and machine here. You take on the role of Kipuna, a "simple village girl" who ends up gaining power over time itself and this is used during combat.

  • Why Open Source continues to be the foundation for modern IT

    Open source technology is no longer an outlier in the modern world, it's the foundation for development and collaboration. Sitting at the base of the open source movement is the Linux Foundation, which despite having the name Linux in its title, is about much more than just Linux and today is comprised of multiple foundations, each seeking to advance open source technology and development processes. At the recent Open Source Summit North America event held in San Diego, the width and breadth of open source was discussed ranging from gaming to networking, to the movie business ,to initiatives that can literally help save humanity. "The cool thing is that no matter whether it's networking, Linux kernel projects, the Cloud Native Computing Foundation projects like Kubernetes, or the film industry with the Academy Software Foundation (ASWF), you know open source is really pushing innovation beyond software and into all sorts of different areas," Jim Zemlin, executive director of the Linux Foundation said during his keynote address.

  • GitLab Inhales $268M Series E, Valuation Hits $2.75B

    GitLab raised a substantial $268 million in a Series E funding round that was more than doubled what the firm had raised across all of its previous funding rounds and pushed its valuation to $2.75 billion. It also bolsters the company’s coffers as it battles in an increasingly competitive DevOps space. GitLab CEO Sid Sijbrandij said in an email to SDxCentral that the new Series E funds will help the company continue to move on its goal of providing a single application to support quicker delivery of software. It claims more than 100,000 organizations use its platform. “These funds will help us to keep up with that pace and add to that with our company engineers,” Sijbrandij explained. “We need to make sure every part of GitLab is great and that CIOs and CTOs who supply the tools for their teams know that if they bet on GitLab that we’ll stand up to their expectations.”

  • How Chrome OS works upstream

    Google has a long and interesting history contributing to the upstream Linux kernel. With Chrome OS, Google has tried to learn from some of the mistakes of its past and is now working with the upstream Linux kernel as much as it can. In a session at the 2019 Open Source Summit North America, Google software engineer Doug Anderson detailed how and why Chrome OS developers work upstream. It is an effort intended to help the Linux community as well as Google. The Chrome OS kernel is at the core of Google's Chromebook devices, and is based on a Linux long-term support (LTS) kernel. Anderson explained that Google picks an LTS kernel every year and all devices produced in that year will use the selected kernel. At least once during a device's lifetime, Google expects to be able to "uprev" (switch to a newer kernel version). Anderson emphasized that if Google didn't upstream its own patches from the Chrome OS kernel, it would make the uprev process substantially more difficult. Simply saying that you'll work upstream and actually working upstream can be two different things. The process by which Chrome OS developers get their patches upstream is similar to how any other patches land in the mainline Linux kernel. What is a bit interesting is the organizational structure and process of how Google has tasked Chrome OS developers to work with upstream. Anderson explained that developers need to submit patches to the kernel mailing list and then be a little patient, giving some time for upstream to respond. A key challenge, however, is when there is no response from upstream. "When developing an upstream-first culture, the biggest problem anyone can face is silence," Anderson said. Anderson emphasized that when submitting a patch to the mailing list, what a developer is looking for is some kind of feedback; whether it's good or bad doesn't matter, but it does matter that someone cares enough to review it. What the Chrome OS team does in the event that there is no community review is it will have other Chrome OS engineers publicly review the patch. The risk and worry of having Chrome OS engineers comment on Chrome OS patches is that the whole process might look a little scripted and there could be the perception of some bias as well. Anderson noted that it is important that only honest feedback and review is given for a patch.

  • What's In A Name? Tales Of Python, Perl, And The GIMP

    In the older days of open source software, major projects tended to have their Benevolent Dictators For Life who made all the final decisions, and some mature projects still operate that way. Guido van Rossum famously called his language “Python” because he liked the British comics of the same name. That’s the sort of thing that only a single developer can get away with. However, in these modern times of GitHub, GitLab, and other collaboration platforms, community-driven decision making has become a more and more common phenomenon, shifting software development towards democracy. People begin to think of themselves as “Python programmers” or “GIMP users” and the name of the project fuses irrevocably with their identity. What happens when software projects fork, develop apart, or otherwise change significantly? Obviously, to prevent confusion, they get a new name, and all of those “Perl Monks” need to become “Raku Monks”. Needless to say, what should be a trivial detail — what we’ve all decided to call this pile of ones and zeros or language constructs — can become a big deal. Don’t believe us? Here are the stories of renaming Python, Perl, and the GIMP.

  • How to teach (yourself) computer programming

    Many fellow students are likely in the same boat, the only difference being that the vast majority not only that don’t list computer science as one of their passions (but more as one of their reasons for not wanting to live anymore), but they get a very distorted view of what computer science and programming actually is.

    Said CS classes tend to be kind of a joke, not only because of the curriculum. The main reason why they are bad and boring is the way they are taught. I am going to address my main frustrations on this matter together with proposed solutions and a guide for those who want to start learning alone.

Server: Ubuntu 19.10 Release Schedule, IBM LinuxONE III with Ubuntu and SUSE on Cloud Foundry Foundation and More LF

  • Ubuntu 19.10 Release Schedule and Expected Features

    This is a continually updated article to inform you about Ubuntu 19.10 release date, features and other important things associated with it. The development for Ubuntu 19.10 is nearing its end and it’s time to look at what new features and improvement this new release brings. Ubuntu 19.10 is an important release because it will set the course of development for Ubuntu 20.04 LTS (long term support). I have always felt that the LTS version release takes a lot of features from its predecessor. In other words, Ubuntu 19.10 will be a glimpse of the features you would be getting in Ubuntu 20.04.

  • The Linux Foundation to Host Open Source Project for Drone Aviation Interoperability

    The Linux Foundation today announced it will host the InterUSS Platform Open Source Project to enable trusted, secure and scalable interoperability between UAS Service Suppliers (USSs) that advances safe, equitable and efficient drone operations. Initial contributors include both industry and regulatory organizations Wing, AirMap, Uber and the Swiss Federal Office of Civil Aviation (FOCA). Similar to the evolution of cities, our skies are becoming busier with traffic. In an effort to unleash innovation and ensure safety, aviation regulators around the world are implementing UAS Traffic Management (UTM, also referred to as U-Space) to support rapidly increasing and highly diverse drone operations. Under UTM, a set of USSs (also known as U-Space Service Providers orUSPs) assist drone operators to conduct safe and compliant operations. USSs can provide service in overlapping airspace and share data when required to support services such as a strategic deconfliction of flight plans and remote identification and industry is developing standards for this data sharing through organizations such as ASTM International. The InterUSS Project provides a forum for collaboration and development of standards-compliant, open source implementations that facilitate communication in the UTM/U-Space environment.

Security Leftovers

  • SGX and security modules

    Software Guard Extensions (SGX) is a set of security-related instructions for Intel processors; it allows the creation of private regions of memory, called "enclaves". The aim of this feature is to work like an inverted sandbox: instead of protecting the system from malicious code, it protects an application from a compromised kernel hypervisor, or other application. Linux support for SGX has existed out-of-tree for years, and the effort of upstreaming it has reached an impressive version 22 of the patch set. During the upstreaming discussion, the kernel developers discovered that the proposed SGX API did not play nicely with existing security mechanisms, including Linux security modules (LSMs).
