-Egor's blog
-===========
-
-Egor's blog on programming.
-Hosted on [GitHub Pages] at https://egor-tensin.github.io/blog/.
-
-[GitHub Pages]: https://pages.github.com
-
-Prerequisites
--------------
-
-[Jekyll] is used to build a set of static HTML pages from a collection of
-templates and resources.
-[Bundler] is used to manage project's dependencies.
-Make sure you have the `bundler` gem installed; project dependencies can then
-be installed by executing
-
-    bundle install
-
-in the project's root directory.
-
-[Jekyll]: https://jekyllrb.com/
-[Bundler]: http://bundler.io/
-
-Usage
------
-
-To run a local web server, execute
-
-    bundle exec jekyll serve --watch --drafts --config _config.yml,_config_dev.yml
-
-in the project's root directory.
-You can then review your changes at http://localhost:4000/.
-
-If you can't get Jekyll to properly `--watch` for file modifications on
-Windows, try adding `--force_polling` to `jekyll`s options:
-
-    bundle exec jekyll serve --watch --force_polling --drafts --config _config.yml,_config_dev.yml
-
-It might still not work though, but you can always re-run `jekyll` manually.
-
-Note that `_config_dev.yml` is included to rewrite some of the `site` fields
-from `_config.yml` during development.
-In particular, it
-
-* sets `minified_externals` to `false` so that the properly formatted versions
-of external CSS stylesheets and JavaScript files are included instead of the
-`min`ified versions,
-* sets `include_comments` to `false` to exclude the Disqus comments section
-from the posts,
-* sets `baseurl` to an empty string so that the website can be accessed from
-local web server's root directory (i.e. from http://localhost:4000/ instead of
-http://localhost:4000/blog/).
-
-### Access via file://
-
-Jekyll doesn't provide native support for generating a static website which can
-be browsed without running an instance of Jekyll's web server.
-One easy workaround is to `wget` the website and convert the links:
-
-    wget --convert-links --recursive http://localhost:4000/
-
-### Typesetting math
-
-[MathJax] can be used to typeset mathematics using LaTeX.
-To use MathJax, set `mathjax` to `true` in page's front matter.
-Then you can do things like this:
-
-```
-This is an inline formula: $$y = kx + b$$.
-This is a formula in a separate block:
-
-$$
-y = kx + b
-$$
-```
-
-[MathJax]: https://www.mathjax.org/
-
-#### GitHub workarounds
-
-MathJax version 3 is used, which is unsupported by Kramdown (which produces
-`<script type="math/tex; ..."` tags, suitable only for MathJax 2.
-This is why `math_engine` is set to `null` in _config.yml, making Kramdown
-output block formulas wrapped in `$$` and inline formulas in `$` respectively
-([inside `<span class="kdmath">` elements][kramdown issue]).
-Because if this, MathJax is additionally customized to recognize `$` as an
-inline formula delimiter in _includes/common/mathjax.html.
-
-GitHub Pages [helpfully overrides] the `math_engine` setting in your
-_config.yml, hardcoding it to `mathjax` instead of `null` (there's a related
-[pull request]).
-I couldn't find a better way than to override the setting in the markdown
-document itself using
-
-    {::options math_engine="+nil+" /}

-(Associative) arrays
---------------------
-
-### Declaration
-
-`"${#xs[@]}"` doesn't work with `nounset` if `xs` wasn't defined, i.e. was
-declared with either of
-
-    local -a xs
-    declare -a xs
-    local -A xs
-    declare -A xs
-
-Therefore, if you want to extract the length of an array, append `=()` to the
-statements above.
-
-    local -a xs=()
-    declare -a xs=()
-    ...
-
-And now `"${#xs[@]}"` works with `nounset`.
-It doesn't affect expansion (see below) though.
-
-### Expansion
-
-#### Do
-
-    func ${arr[@]+"${arr[@]}"}
-
-#### Don't
-
-    func "${arr[@]}"                # Doesn't work with `nounset`.
-    func "${arr[@]+"${arr[@]}"}"    # Doesn't work properly with `declare -a arr=('')`.
-
-### `unset`
-
-#### Do
-
-    unset -v 'arr[x]'
-    unset -v 'arr[$i]'
-
-#### Don't
-
-    unset -v arr[x]         # May break due to globbing.
-    unset -v arr[$i]        # The same as above + a possible problem with quotation.
-    unset -v 'arr["x"]'     # Doesn't work for some reason.
-    unset -v 'arr["]"]'     # The same as above; just highlighting the problem with funny characters in array indices.
-    unset -v 'arr["$i"]'    # Also rejected.
-
-    # An insightful discussion on the topic: https://lists.gnu.org/archive/html/help-bash/2016-09/msg00020.html.
-
-`errexit`
----------
-
-### Do
-
-    bar_output="$( bar )"
-    foo "$bar_output"
-
-### Don't
-
-    foo "$( bar )"    # With `errexit`, foo will still get executed.
-                      # I don't know why.

-* `diff`- and HTML-friendliness is valued over human-readability.
-* Every sentence starts on a new line ("semantic newlines").
-* Lines are at most 79 characters long, not counting neither the carriage
-return, nor the line feed characters.
-    * Not 80 characters, because when you display a 80-character line with a
-line feed at the end in Windows' `cmd`, an extra empty line is added.
-* No hanging indents in lists.
-    * Nested lists are indented with 4 spaces.
-    * No hanging indents in those also.
-    * Longer items wrap at 79 characters and continue from the leftmost
-character column.
-Additional sentences start there also.
-* Prefer reference-style links over inline links.
-Omit the second pair of brackets `[]` entirely where appropriate.
-For example, [Google] is preferred over both [Google](https://ya.ru) and
-[I'm feeeling lucky][google] (see [this document's source]).
-* First- and second-level headers are underlined with strings of `=` and `-`.
-The number of `=`/`-` signs must be equal to the number of characters in the
-header.
-* File paths are enclosed in double quotes.
-Environment variable names are enclosed in a pair of backticks (\`) unless it's
-a part of a path.
-Executable names are enclosed in a pair of backticks (\`) unless it's a part of

-title: std::call_once bug in Visual C++ 2012/2013
-excerpt: >
-  In this post I will describe a nasty bug I've stumbled upon in the C++
-  Standard Library implementation shipped with Microsoft Visual Studio
-  2012/2013.
-category: C++
-custom_css:
-  - syntax.css
----
-I've recently come across a nasty standard library bug in the implementation
-shipped with Microsoft Visual Studio 2012/2013.
-[StackOverflow was of no help], so I had to somehow report the bug to the
-maintainers.
-Oddly enough, Visual Studio's [Connect page] wouldn't let me report one,
-complaining about the lack of permissions, even though I was logged in from my
-work account, associated with my Visual Studio 2013 installation.
-
-Fortunately, I've come across the personal website of this amazing guy,
-[Stephan T. Lavavej], who appears to be the chief maintainer of Microsoft's
-standard library implementation.
-He seems to be your go-to guy when it comes to obvious standard library
-misbehaviours.
-

-
-C++11 and singletons
---------------------
-
-Anyway, the story begins with me trying to implement the singleton pattern
-using C++11 facilities like this:
-
-```c++
-#include <mutex>
-
-template <typename Derived>
-class Singleton {
-public:
-    static Derived& get_instance() {
-        std::call_once(initialized_flag, &initialize_instance);
-        return Derived::get_instance_unsafe();
-    }
-
-protected:
-    Singleton() = default;
-    ~Singleton() = default;
-
-    static Derived& get_instance_unsafe() {
-        static Derived instance;
-        return instance;
-    }
-
-private:
-    static void initialize_instance() {
-        Derived::get_instance_unsafe();
-    }
-
-    static std::once_flag initialized_flag;
-
-    Singleton(const Singleton&) = delete;
-    Singleton& operator=(const Singleton&) = delete;
-};
-
-template <typename Derived>
-std::once_flag Singleton<Derived>::initialized_flag;
-```
-
-Neat, huh?
-Now other classes can inherit from `Singleton`, implementing the singleton
-pattern effortlessly:
-
-```c++
-class Logger : public Singleton<Logger> {
-private:
-    Logger() = default;
-    ~Logger() = default;
-
-    friend class Singleton<Logger>;
-};
-```
-
-Note that the [N2660] standard proposal isn't/wasn't implemented in the
-compilers shipped with Visual Studio 2012/2013.
-If it was, I wouldn't, of course, need to employ this `std::call_once`
-trickery, and the implementation would be much simpler, i.e. something like
-this:
-
-```c++
-class Logger {
-public:
-    static Logger& get_instance() {
-        static Logger instance;
-        return instance;
-    }
-
-private:
-    Logger() = default;
-    ~Logger() = default;
-};
-```
-
-<div class="alert alert-info" markdown="1">
-
-The point is that the `Logger::get_instance` routine above wasn't thread-safe
-until C++11.
-Imagine what might happen if `Logger`'s constructor takes some time to
-initialize the instance.
-If a couple of threads then call `get_instance`, the first thread might begin
-the initialization process, making the other thread believe that the instance
-had already been intialized.
-This other thread might then return a reference to the instance which hasn't
-yet completed its initialization and is most likely unsafe to use.
-    
-Since C++11 includes the proposal mentioned above, this routine would indeed be
-thread-safe in C++11.
-Unfortunately, the compilers shipped with Visual Studio 2012/2013 don't/didn't
-implement this particular proposal, which caused me to look at
-`std::call_once`, which seemed to implement exactly what I needed.

-
-Problem
--------
-
-Unfortunately, matters became a bit more complicated when I tried to introduce
-two singletons, one having a dependency on the other.
-I had `Logger`, like in the example above, and some kind of a "master"
-singleton (let's call it `Duke`).
-`Duke`'s constructor was complicated and time-consuming, and definetely
-required some logging to be done.
-I thought that I could simply call `Logger::get_instance` inside `Duke`'s
-constructor, and everything looked fine at first glance.
-
-```c++
-#include <chrono>
-#include <thread>
-
-class Logger : public Singleton<Logger> {
-public:
-    Logger& operator<<(const char* msg) {
-        // Actual logging is stripped for brevity.
-        return *this;
-    }
-
-private:
-    Logger() {
-        // Opening log files, etc.
-        std::this_thread::sleep_for(std::chrono::seconds{3});
-    }
-
-    ~Logger() = default;
-
-    friend class Singleton<Logger>;
-};
-
-class Duke : public Singleton<Duke> {
-private:
-    Duke() {
-        Logger::get_instance() << "started Duke's initialization";
-        // It's a lot of work to be done.
-        std::this_thread::sleep_for(std::chrono::seconds{10});
-        Logger::get_instance() << "finishing Duke's initialization";
-    }
-
-    ~Duke() = default;
-
-    friend class Singleton<Duke>;
-};
-```
-
-Now, what happens if I have two threads, one using the `Duke` instance, and the
-other logging something?
-Like in this example:
-
-```c++
-#include <thread>
-
-namespace {
-
-void get_logger() {
-    entered(__FUNCTION__);
-    Logger::get_instance();
-    exiting(__FUNCTION__);
-}
-
-void get_duke() {
-    entered(__FUNCTION__);
-    Duke::get_instance();
-    exiting(__FUNCTION__);
-}
-
-}
-
-int main() {
-    std::thread t1{&get_duke};
-    std::thread t2{&get_logger};
-    t1.join();
-    t2.join();
-    return 0;
-}
-```
-
-`entered` and `exiting` are utility functions to print timestamps.
-The implementation is included in the [complete code sample].
-{: .alert .alert-info }
-
-The first thread is supposed to have the total running time of about 13
-seconds, right?
-Three seconds to initialize the `Logger` instance and ten to initialize the
-`Duke` instance.
-The second thread, similarly, is supposed to be done in about 3 seconds
-required for the initialization of `Logger`.
-
-Weirdly, this program produces the following output when compiled using Visual
-Studio 2013's compiler:
-
-    Entered `anonymous-namespace'::get_duke at Fri Jul 03 02:26:16 2015
-    Entered `anonymous-namespace'::get_logger at Fri Jul 03 02:26:16 2015
-    Exiting `anonymous-namespace'::get_duke at Fri Jul 03 02:26:29 2015
-    Exiting `anonymous-namespace'::get_logger at Fri Jul 03 02:26:29 2015
-
-Isn't it wrong that the second thread actually took the same 13 seconds as the
-first thread?
-Better check with some other compiler in case it was me who made a mistake.
-Unfortunately, the program behaves as expected when compiled using GCC:
-
-    Entered get_logger at Fri Jul  3 02:27:12 2015
-    Entered get_duke at Fri Jul  3 02:27:12 2015
-    Exiting get_logger at Fri Jul  3 02:27:15 2015
-    Exiting get_duke at Fri Jul  3 02:27:25 2015
-
-So it appears that the implementation of `std::call_once` shipped with Visual
-Studio 2012/2013 relies on some kind of a global lock, which causes even the
-simple example above to misbehave.
-
-The [complete code sample] to demonstrate the misbehaviour described above can
-be found in this blog's repository.
-
-[complete code sample]: {{ site.github.repository_url }}/tree/master/std_call_once_bug
-
-Resolution
-----------
-
-So, since I couldn't submit the bug via Visual Studio's [Connect page], I wrote
-to Mr. Lavavej directly, not hoping for an answer.
-Amazingly, it took him less than a day to reply.
-He told me he was planning to overhaul `std::call_once` for Visual Studio 2015.
-Meanwhile, I had to stick to something else; I think I either dropped logging
-from `Duke`'s constructor or initialized all the singleton instances manually
-before actually using any of them.
-In a few months, Mr. Lavavej replied to me that the bug has been fixed in
-Visual Studio 2015 RTM.
-I would like to thank him for the professionalism and responsibility he's
-shown.

-title: Building Boost on Windows
-excerpt: >
-  This post describes the process of building Boost on Windows using either
-  Visual Studio or the combination of Cygwin + MinGW-w64.
-category: C++
-custom_css:
-  - syntax.css
----
-Below you can find the steps required to build Boost libraries on Windows.
-These steps tightly fit my typical workflow, which is to use Boost libraries in
-CMake builds using either Visual Studio or the combination of Cygwin +
-MinGW-w64.
-I would expect, however, that the procedure for the latter toolset can easily
-be adjusted for generic GCC distributions (including vanilla GCCs found in
-popular Linux distributions).
-
-One of the features of this workflow is that I build throwaway, "run
-everywhere, record the results, and scrap it" executables more often than not,
-so I prefer to link everything statically, including, for instance, C/C++
-runtimes.
-This is implemented by passing `runtime-link=static` to Boost's build utility
-`b2`; change this to `runtime-link=dynamic` to link the runtime dynamically.
-
-Excerpts from shell sessions in this post feature a few different commands
-besides Boost's `b2` and `cmake`, like `cd` and `cat`.
-They are used to hint at my personal directory layout, display various
-auxiliary files, etc.
-Windows' `cd`, for example, simply prints the current working directory;
-Cygwin's `pwd` serves the same purpose.
-`cat` is used to display files.
-Windows' command prompts are denoted with `>`s at the beginning of each line;
-Cygwin's &mdash; with `$`s.
-
-Visual Studio
--------------
-
-Statically-linked Boost libraries are built, both the debug and the release
-versions of them (these are default settings).
-While it is required to keep x86 and x64 libraries in different directories (to
-avoid file name clashes), it's not necessary to separate debug libraries from
-their release counterparts, because that information is actually encoded in
-file names (the "gd" suffix).
-
-### x86
-
-```
-> cd
-D:\workspace\third-party\boost_1_61_0\msvc
-
-> bootstrap
-...
-
-> b2 --stagedir=stage\x86  ^
-    runtime-link=static    ^
-    --with-filesystem      ^
-    --with-program_options ^
-    ...
-...
-```
-
-### x64
-
-The only important difference is that you have to pass `address-model=64` to
-`b2` (notice also the different "staging" directory).
-
-```
-> cd
-D:\workspace\third-party\boost_1_61_0\msvc
-
-> bootstrap
-...
-
-> b2 --stagedir=stage\x64  ^
-    runtime-link=static    ^
-    address-model=64       ^
-    --with-filesystem      ^
-    --with-program_options ^
-    ...
-...
-```
-
-Cygwin + MinGW-w64
-------------------
-
-Contrary to the Visual Studio example above, it is required to store debug and
-release libraries *as well as* x86 and x64 libraries in different directories.
-It is required to avoid file name clashes; unlike the Visual Studio "toolset"
-(in Boost's terms), GCC-derived toolsets don't encode any information (like
-whether the debug or the release version of a library was built) in file names.
-
-Also, linking the runtime statically doesn't really make sense for MinGW, as it
-always links to msvcrt.dll, which is [simply the Visual Studio 6.0 runtime].
-
-[simply the Visual Studio 6.0 runtime]: https://sourceforge.net/p/mingw-w64/wiki2/The%20case%20against%20msvcrt.dll/
-
-In the examples below, only the debug versions of the libraries are built.
-Build the release versions by executing the same command, and substituting
-`variant=release` instead of `variant=debug` and either
-`--stagedir=stage/x86/release` or `--stagedir=stage/x64/release`, depending
-on the target architecture.
-
-### x86

-
-The "user" configuration file above stopped working at some point; not sure as
-to who's to blame, Cygwin or Boost.
-If you see something like "`error: provided command 'i686-w64-mingw32-g++' not
-found`", add ".exe" to the binary name above, so that the whole file reads
-"`using gcc : : i686-w64-mingw32-g++.exe ;`".
-{: .alert .alert-info }
-
-### x64
-
-Notice the two major differences from the x86 example:
-
-* the addition of `address-model=64` (as in the example for Visual Studio),
-* the different "user" configuration file, pointing to `x86_64-w64-mingw32-g++`
-instead of `i686-w64-mingw32-g++`.
-
-Again, as in the example for Visual Studio, a different "staging" directory
-needs to be specified using the `--stagedir` parameter.

----
-In this post I'll try to figure out whether I should use `static`, `inline` or
-unnamed namespaces for function definitions.
-
-`static`
---------
-
-It's an old C-style method of defining functions in header files.
-This way, every translation unit gets its own copy of a function.
-What does that mean?
-The most obvious implication that pops into my head is that every local static
-variable defined inside that function gets an independent replica in every
-translation unit.
-For example, the program below would print
-
-```
-1
-1
-```
-
-due to the fact that both main.cpp and proxy.cpp get their own versions of `n`
-from `shared()`.
-
-{% include snippets/section.html section_id='static' %}
-
-In C, this is the only way to share function definitions between translation
-units (apart from the usual way of declaring a function in a header file and
-putting its definition to a .c file).
-
-### Properties
-
-* Using `static`, you can share function definitions between multiple
-translation units.
-* Each unit gets its own replica of the function: they have different
-addresses, their local static variables are independent, etc.
-* If different translation units define different functions with the same
-name using the `static` specifier, each unit can use its function without any
-issues.
-This might seem like an trivial claim, but other approaches sometimes disallow
-this, which is discussed below.
-
-`inline`
---------
-
-It's well-known that this keyword has pretty much nothing to do with whether a
-function will actually be inlined or not.
-It's used much more often to define functions in header files, since every
-function defined this way will be the same (as in "will have the same address")
-in every translation unit.
-Let's try and adjust the definition of `shared()` accordingly:
-
-{% include snippets/section.html section_id='inline' %}
-
-The same program would then print
-
-```
-1
-2
-```
-
-since both `main()` and `proxy()` would call the same `shared()`, incrementing
-the same `n`.
-
-Weird things happen when different translation units define different `inline`
-functions with the same name.
-
-{% include snippets/section.html section_id='inline_weird' %}
-
-According to my simple experiments, this program produces different output
-based on which .cpp file was specified first on the command line during
-compilation.
-For example, this is the output of test.exe produced with either `cl /W4 /EHsc
-main.cpp another.cpp /Fe:test.exe` or `g++ -Wall -Wextra -std=c++11 main.cpp
-another.cpp -o test.exe`.
-
-```
-main.cpp: shared()
-main.cpp: shared()
-```
-
-If we swap the order of .cpp files (`another.cpp main.cpp` instead of `main.cpp
-another.cpp`), the output becomes
-
-```
-another.cpp: shared()
-another.cpp: shared()
-```
-
-No warnings/errors are emitted, making the situation truly disturbing.
-I tested this with GNU compiler version 5.4.0 and Microsoft compiler version
-19.00.24210.
-
-This behaviour can be easily fixed either by making these functions `static` or
-by using unnamed namespaces (see below).
-
-### Properties
-
-* Using `inline`, you can share function definitions between multiple
-translation units.
-* Each translation unit will use the same function: it will have the same
-address in every translation unit, its local static variables will be shared,
-etc.
-* Defining different `inline` functions with the same name in different
-translation units is undefined behaviour.
-
-Two inline functions might be different even if they are the same textually.
-For example, they might reference two global variables which have the same
-name, but are defined in different translation units.
-{: .alert .alert-info }
-
-`namespace {`
--------------
-
-With respect to function definitions, unnamed namespaces are, according to my
-understanding, quite similar to the `static` keyword.
-The additional value they provide is that they provide a way to apply `static`
-not only to functions, but to classes also.
-Remember the weirdness that happens when multiple translation units define
-different `inline` functions with the same name?
-Arguably, it gets even worse if we add classes to the equation.
-
-{% include snippets/section.html section_id='unnamed_namespaces_weird' %}
-
-Compiling this program the same way we did in the `inline` example (`cl /W4
-/EHsc main.cpp another.cpp /Fe:test.exe`/`g++ -Wall -Wextra -std=c++11 main.cpp
-another.cpp -o test.exe`) yields different outputs depending on which .cpp file
-was specified first.
-
-```
-main.cpp: Test::Test()
-1
-main.cpp: Test::Test()
-```
-
-```
-another.cpp: Test::Test()
-1065353216
-another.cpp: Test::Test()
-```
-
-I'm not sure why anybody would want that.
-This can be easily fixed by putting both `Test` classes into unnamed
-namespaces.
-The program than reads
-
-{% include snippets/section.html section_id='unnamed_namespaces_ok' %}
-
-After the adjustment, it produces the same output regardless of compilation
-options.
-
-```
-main.cpp: Test::Test()
-1
-another.cpp: Test::Test()
-```
-
-Notice how sharing classes defined in header files isn't discussed here.
-The standard actually guarantees that if a class is defined in a header file,
-all translation units that use it share the definition.
-
-### Properties
-
-* Essentially, unnamed namespaces allow the `static` keyword to be applied to
-classes.
-* Similar to the `static` approach, each translation unit gets its own replica
-of a function/class, including their own local static variables, etc.
-* Defining different classes with the same name in different translation units
-(without utilizing unnamed namespaces) is undefined behaviour.
-
-Conclusion
-----------
-
-Here's my attempt to build an algorithm to decide whether a class/function
-should be defined with either of the `static`/`inline` specifiers or put into
-an unnamed namespace.
-The first question I answer is: is the entity defined in a header file or in a
-.cpp file?
-
-* **In a header** &mdash; Is it a class or a function?
-    * **Class** &mdash; There's no need to do anything.
-    * **Function** &mdash; Do you want it to behave differently for each
-translation unit (may be useful, for example, for logging)?
-        * **Yes** &mdash; Use `static`.
-        * **No** &mdash; Use `inline`.
-* **In a .cpp file** &mdash; Put it into an unnamed namespace.
-
-Tricky cases
-------------
-
-### `static` + `inline`
-
-In case a function is defined as `static inline`, `static` wins, and `inline`
-is ignored.
-The program below outputs
-
-```
-1
-1
-```
-
-{% include snippets/section.html section_id='static_and_inline' %}
-
-In general, I can't think of a reason to define a `static inline` function.
-
-### `namespace {` + `inline`
-
-If an `inline` function is defined in an unnamed namespace, the unnamed
-namespace wins.
-The program below outputs
-
-```
-1
-1
-```
-
-{% include snippets/section.html section_id='unnamed_namespace_and_inline' %}
-
-In general, I can't think of a reason to define an `inline` function in an
-unnamed namespace.
-
-### Separate method definitions
-
-If you want to separate your class declaration from its method definitions
-while keeping them in the same header file, each method must be explicitly
-defined `inline`.
-The program below outputs
-
-```
-1
-2
-```
-
-{% include snippets/section.html section_id='separate_method_definitions' %}

-  blocks.
-category: Haskell
-custom_css:
-  - syntax.css
----
-I've fallen into a Haskell indentation pitfall.
-I think it must be common, so I'm describing it here.
-
-The problem is that indentation rules in `do` blocks are not intuitive to me.
-For example, the following function is valid Haskell syntax:
-
-```haskell
-foo1 :: IO ()
-foo1 =
-    alloca $ \a ->
-    alloca $ \b ->
-    alloca $ \c -> do
-        poke a (1 :: Int)
-        poke b (1 :: Int)
-        poke c (1 :: Int)
-        return ()
-```
-
-In fact, this funnier version is also OK:
-
-```haskell
-foo2 :: IO ()
-foo2 = alloca $ \a ->
-     alloca $ \b ->
-   alloca $ \c -> do
-       poke a (1 :: Int)
-       poke b (1 :: Int)
-       poke c (1 :: Int)
-       return ()
-```
-
-If you add an outer `do` however, things become a little more complicated.
-For example, this is the valid version of the functions above with an outer
-`do`:
-
-```haskell
-foo3 :: IO ()
-foo3 = do
-    alloca $ \a ->
-        alloca $ \b ->
-            alloca $ \c -> do
-                poke a (1 :: Int)
-                poke b (1 :: Int)
-                poke c (1 :: Int)
-                return ()
-```
-
-Notice the extra indentation for each of the `alloca`s.
-When I tried to remove these seemingly excessive indents, GHC complained with
-the usual `parse error (possibly incorrect indentation or mismatched
-brackets)`.
-
-```haskell
-foo4 :: IO ()
-foo4 = do
-    alloca $ \a ->
-    alloca $ \b ->
-    alloca $ \c -> do
-        poke a (1 :: Int)
-        poke b (1 :: Int)
-        poke c (1 :: Int)
-        return ()
-```
-
-The truth is, the rules for desugaring `do` blocks are surprisingly simple and
-literal.
-GHC inserts semicolons according to the rules [found in the Wikibook].
-So it inserts semicolons between the `alloca`s on the same level, so `foo4`
-becomes:
-
-```haskell
-foo4 :: IO ()
-foo4 = do
-    { alloca $ \a ->
-    ; alloca $ \b ->
-    ; alloca $ \c -> do
-        { poke a (1 :: Int)
-        ; poke b (1 :: Int)
-        ; poke c (1 :: Int)
-        ; return ()
-        }
-    }
-```
-
-[found in the Wikibook]: https://en.wikibooks.org/wiki/Haskell/Indentation#Explicit_characters_in_place_of_indentation
-
-The semicolons after `->` are clearly invalid Haskell syntax, hence the error.
-
-P.S. To compile the functions above, you need to include them in a module and
-add proper imports, e.g.
-
-```haskell
-module PeculiarIndentation where
-
-import Foreign.Marshal.Alloc (alloca)
-import Foreign.Storable      (poke)
-```

-First, let's determine that

-\newcommand\naturals{\mathbb{N}}
-\newcommand\rationals{\mathbb{Q}}
-\newcommand\reals{\mathbb{R}}
-
-\newcommand\xs{x_{1}x_{2}\dots x_n}
-\newcommand\nines{\overbrace{99\dots 9}^n}
-\newcommand\pq{\frac{p}{q}}
-\newcommand\qp{\frac{q}{p}}
-
-0.(9) = 1
-$$
-
-This may seem counter-intuitive, but demonstrably true.
-If $$0.(9) \neq 1$$, then $$\exists n \in \reals: 0.(9) < n < 1$$.
-To put it another way, there must be a number greater than 0.(9) and lesser
-than 1, equal to neither.
-Thinking about it makes it obvious this is not true.
-
-Slightly more formally,
-
-$$
-\begin{align*}
-1 - 0.9 &= \frac{1}{10} \\
-1 - 0.99 &= \frac{1}{100} \\
-1 - 0.999 &= \frac{1}{10^{-3}} \\
-\dots \\
-1 - 0.\nines &= \frac{1}{10^n} \\
-\end{align*}
-$$
-
-If $$0.(9) \neq 1$$, the following must hold:
-
-$$
-\forall n \in \naturals, \exists x \in \reals: x < \frac{1}{10^n}
-$$
-
-It's clear that the only such number is 0, making 0.(9) and 1 equal.
-
-Let $$n \in [1,9]$$.
-Is there $$\pq \in \rationals: \pq = 0.(n)$$?
-
-For $$n = 9$$, we've established $$p = 1, q = 1$$.
-For the other values of $$n$$ we can observe that
-
-$$
-\begin{align*}
-0.(1) \times 9 &= 0.(9) = 1 \\
-0.(2) \times 9/2 &= 0.(9) = 1 \\
-0.(3) \times 9/3 &= 0.(9) \\
-\dots \\
-0.(8) \times 9/8 &= 0.(9) \\
-0.(9) \times 1 &= 0.(9)
-\end{align*}
-$$
-
-So,
-
-$$
-\forall n \in [1,9], \frac{n}{9} = 0.(n)
-$$
-
-In general, let's demonstrate that
-
-$$
-\forall n \in \naturals, n > 0, \forall 0.(x_{1}x_{2}\dots x_n), \exists \pq \in \rationals: \pq = 0.(\xs)
-$$
-
-Let $$p = \xs, q =\,\nines$$.
-It's clear that
-
-$$
-\begin{align*}
-0.(\xs) \times \qp &= 0.(\xs) \times \frac{\nines}{\xs} \\
-&= \left(\frac{\xs}{10^n} + \frac{\xs}{10^{2n}} + \dots\right) \times \frac{\nines}{\xs} \\
-&= \left(\frac{1}{10^n} + \frac{1}{10^{2n}} + \dots\right) \times\,\nines \\
-&= 0.(9) \\
-&= 1
-\end{align*}
-$$
-
-Finally, $$0.(\xs) \times \qp = 1 \implies \pq = 0.(\xs)$$.

-title: Persistent SSH tunnel
-excerpt: ... using Cygwin.
----
-SSH tunneling is awesome.
-For some reason, I've only recently learned about this feature, but I've been
-immediately blown away by how useful it can be.
-
-Basically, to use SSH tunneling (a.k.a. port forwarding) you need to have a SSH
-client (`ssh`) with an access to a SSH server.
-You can then access any port on any host your SSH server has access to.
-It works like this:
-
-* your SSH client establishes a connection to the SSH server,
-* the client asks the server to forward incoming requests to the destination
-host,
-* the client listens to the proxy port on the local machine, and forwards
-requests to the SSH server.
-
-Say, you have access to SSH server `gateway` on port 22, and you want to gain
-access to HTTPS server `dest` on port 443, which is only accessible from the
-network both it and the SSH server belong to.
-You can then run something like
-
-```
-ssh -L 4433:dest:443 gateway -p 22
-```
-
-And now you can access `dest` at `https://localhost:4433/`.
-That's brilliant, really.
-
-But there's more.
-You can make a _reverse_ tunnel, allowing you to give access to any host your
-client computer has access to, via a remote SSH server.
-It works like this:
-
-* your SSH client establishes a connection with the SSH server,
-* the client asks the server to listen to a port of your choosing and forward
-incoming requests to the client,
-* the client forwards incoming requests to the destination host.
-
-This, as I've recently learned, is a common pattern to subvert corporate
-firewalls, which frequently forbid incoming connections.
-Say, you want to access your work computer from home via RDP.
-Both your home and your work computers have access to a SSH server `gateway` on
-port 22 (you might want to change it to port 80 or 443 if your outside
-connections are filtered).
-
-You can then run something like (notice the `-R`)
-
-```
-ssh -R 13389:127.0.0.1:3389 gateway -p 22
-```
-
-and now you can connect to `gateway:13389` from your home computer using a RDP
-client.
-Even more brilliant!
-
-You might need to set the `GatewayPorts` setting to `yes` or `clientspecified`
-on your SSH server (typically in "/etc/ssh/sshd_config").
-
-Batch mode
-----------
-
-If you want to establish a reverse SSH tunnel automatically, some tweaking is
-required.
-First, set some SSH client options:
-
-* `-F /dev/null` to disregard the user config,
-* `-oBatchMode=yes` to run non-interactively,
-* `-oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null` to disable server
-verification (optional),
-* `-oExitOnForwardFailure=yes` to exit if port forwarding fails,
-* `-oServerAliveCountMax=3 -oServerAliveInterval=15` to break the connection if
-the server or the network is down,
-* `-N -n -T` to only forward the ports and not execute the shell or any
-additional commands.
-
-Thus, the full command would be something like
-
-```
-ssh                                \
-    -F /dev/null                   \
-    -oBatchMode=yes                \
-    -oStrictHostKeyChecking=no     \
-    -oUserKnownHostsFile=/dev/null \
-    -oExitOnForwardFailure=yes     \
-    -oServerAliveCountMax=3        \
-    -oServerAliveInterval=15       \
-    -N -n -T                       \
-    -R 13389:127.0.0.1:3389        \
-    user@gateway -p 22             \
-    -i ~/.ssh/tunnel
-```
-
-Adjust the `user@gateway -p 22` part accordingly.
-
-Notice also `-i ~/.ssh/tunnel`.
-It's the path to the SSH key used to authenticate with the server.
-It can't have a passphrase, since the command will be run non-interactively,
-and the public key must be in the server's authorized_keys file.
-
-For best results, you should also adjust some settings on the SSH server.
-Namely, you should enable client keep-alives on the server using something like
-
-```
-ClientAliveCountMax 3
-ClientAliveInterval 15
-```
-
-Unless you do that, even if the client breaks the connection, you won't be able
-to re-establish it for a long-ish time, since the server wouldn't know that the
-original connection is no longer valid.
-
-As a service
-------------
-
-Cygwin is awesome.
-I've been using for 10+ years, and it has never failed me.
-It comes with a SSH server, a client (you need to install the `openssh` package
-for both of these), and a service manager, `cygrunsrv`.
-`cygrunsrv` is similar to [NSSM], as it allows to wrap any executable into a
-native Windows service.
-
-[NSSM]: https://nssm.cc/
-
-Using `cygrunsrv`, you can create a Windows service to establish a reverse SSH
-tunnel automatically.
-
-```
-cygrunsrv                        \
-    -I ssh_tunnel                \
-    -p /usr/bin/ssh              \
-    --args '-F /dev/null -oBatchMode=yes -oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null -oExitOnForwardFailure=yes -oServerAliveCountMax=3 -oServerAliveInterval=15 -N -n -T -R 13389:127.0.0.1:3389 user@gateway -p 22 -i ~/.ssh/tunnel' \
-    --disp 'Reverse SSH tunnels' \
-    --user user                  \
-    --neverexits                 \
-    --preshutdown
-```
-
-Adjust the `--user` and the `--args` values accordingly.
-
-You can then run `services.msc` and adjust the recovery settings for the
-service to restart if `ssh` fails:
-
-<div class="row">
-  <div class="col-xs-12 col-sm-8 col-md-6">
-    <a href="{{ site.baseurl }}/img/ssh_tunnel_services.png" class="thumbnail">
-      <img class="img-responsive" alt="services.msc" src="{{ site.baseurl }}/img/ssh_tunnel_services.png">
-    </a>
-  </div>
-</div>
-
-And voilà, you have an automatic reverse SSH tunnel on Windows for you!

-title: 'Docker: bind mounts & file ownership'
-excerpt: Docker + bind mounts + non-root users = pain.
----
-If you want to:
-
-1. run your Docker service as a user other than root,
-2. share a writable directory between your host and the container,
-
-you're in for a treat!
-The thing is, files stored in the shared directory retain their ownership (and
-by that I mean their UIDs and GIDs, as they're the only thing that matters)
-after being mounted in the container.
-
-Case in point:
-
-    docker run -it --rm -v "$( pwd ):/data" alpine touch /data/test.txt
-
-would create file ./test.txt owned by root:root.
-
-You can fix that by using the `--user` parameter:
-
-    docker run -it --rm -v "$( pwd ):/data" --user "$( id -u ):$( id -g )" alpine touch /data/test.txt
-
-That would create file ./test.txt owned by the current user (if the current
-working directory is writable by the current user, of course).
-
-More often though, instead of a simple `touch` call, you have a 24/7 service,
-which absolutely mustn't run as root, regardless of whether `--user` was
-specified or not.
-In such cases, the logical solution would be to create a regular user in the
-container, and use it to run the service.
-In fact, that's what many popular images do, i.e. [Redis][Redis Dockerfile] and
-[MongoDB][MongoDB Dockerfile].
-
-[Redis Dockerfile]: https://github.com/docker-library/redis/blob/cc1b618d51eb5f6bf6e3a03c7842317b38dbd7f9/6.0/Dockerfile#L4
-[MongoDB Dockerfile]: https://github.com/docker-library/mongo/blob/5cbf7be9a486932b7e472a39e432c9a444628465/4.2/Dockerfile#L4
-
-How do you run the service as regular user though?
-It's tempting to use the `USER` directive in the Dockerfile, but that can be
-overridden by `--user`:
-
-    $ cat Dockerfile
-    FROM alpine
-    
-    RUN addgroup --gid 9099 test-group && \
-        adduser \
-            --disabled-password \
-            --gecos '' \
-            --home /home/test-user \
-            --ingroup test-group \
-            --uid 9099 \
-            test-user
-    
-    RUN touch /root.txt
-    USER test-user:test-group
-    RUN touch /home/test-user/test-user.txt
-    
-    CMD id && stat -c '%U %G' /root.txt && stat -c '%U %G' /home/test-user/test-user.txt
-
-    $ docker build -t id .
-    ...
-
-    $ docker run -it --rm id
-    uid=9099(test-user) gid=9099(test-group)
-    root root
-    test-user test-group
-
-    $ docker run -it --rm --user root id
-    uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video)
-    root root
-    test-user test-group
-
-I suppose that's the reason why many popular images override ENTRYPOINT, using
-a custom script (and `gosu`, which is basically `sudo`, I think) to forcefully
-drop privileges (for example, see [Redis][Redis entrypoint],
-[MongoDB][MongoDB entrypoint]).
-
-[Redis entrypoint]: https://github.com/docker-library/redis/blob/cc1b618d51eb5f6bf6e3a03c7842317b38dbd7f9/6.0/docker-entrypoint.sh#L11
-[MongoDB entrypoint]: https://github.com/docker-library/mongo/blob/5cbf7be9a486932b7e472a39e432c9a444628465/4.2/docker-entrypoint.sh#L12
-
-Now, what if such service needs persistent storage?
-A good solution would be to use Docker volumes.
-For development though, you often need to just share a directory between your
-host and the container, and it has to be writable by both the host and the
-container process.
-This can be accomplished using _bind mounts_.
-For example, let's try to map ./data to /data inside a Redis container (this
-assumes ./data doesn't exist and you're running as regular user with UID 1000;
-press Ctrl+C to stop Redis):
-
-    $ mkdir data
-
-    $ stat -c '%u' data
-    1000
-
-    $ docker run -it --rm --name redis -v "$( pwd )/data:/data" redis:6.0
-    ...
-
-    $ stat -c '%u' data
-    999
-
-As you can see, ./data changed its owner from user with UID 1000 (the host
-user) to user with UID 999 (the `redis` user inside the container).
-This is done in Redis' ENTRYPOINT script, just before dropping root privileges
-so that the `redis-server` process owns the /data directory and thus can write
-to it.
-
-If you want to preserve ./data ownership, Redis' image (and many others)
-explicitly accomodates for it by _not_ changing its owner if the container is
-run as anybody other than root.
-For example:
-
-    $ mkdir data
-
-    $ stat -c '%u' data
-    1000
-
-    $ docker run -it --rm --name redis -v "$( pwd )/data:/data" --user "$( id -u ):$( id -g )" redis:6.0
-    ...
-
-    $ stat -c '%u' data
-    1000
-
-Sometimes `--user` is not enough though.
-That specified user is almost certainly missing from container's /etc/passwd,
-it doesn't have a $HOME, etc.
-All of that could cause problems with some applications.
-
-One scenario I had to deal with is making an image that bundles all the gems
-(and a specific Ruby version) for my Ruby web application.
-That application shouldn't be run as root, but it must be able to pick up code
-changes on the fly, and I should be able `docker exec` into the container,
-update the dependencies (along with Gemfile[.lock], and those changes should be
-reflected on the host without messing up file metadata), and restart the app.
-It's quite easy to install the dependencies in the Dockerfile, but they (along
-with the mapped Gemfile[.lock]) should be writable by the user running the
-service.
-The solution often suggested is to create a container user with a fixed UID
-(that would match the host user UID).
-That way, it would be able to update the dependencies stored in the container,
-as well as write to the bind mount owned by the host user with the same UID.
-Additionally, file ownership info would be preserved on the host!
-
-We can create a user with a fixed UID when
-
-1. building the image (using build `ARG`uments),
-2. first starting the container by passing the required UID using environment
-variables.
-
-The advantages of creating the user when building the image is that we can also
-install the dependencies in the Dockerfile, thus eliminating the need to
-rebuild them for every other application.
-The disadvantage is that the image would need to be rebuilt for every user on
-every machine.
-
-Creating the user when first starting the container has the advantage of not
-requiring image rebuilds.
-But, as the dependencies need to be installed after creating the user, you'd
-have to waste resources by installing them for every user and every app on
-every machine (each time when creating a container).
-
-For my project [jekyll-docker] I opted for the former approach, making sure the
-`jekyll` process runs with the same UID as the user who built the image (unless
-it was built by root, in which case it falls back to a custom UID of 999).
