       Recently [benchmark for concurrency implementation in different

     

       14
       +
       languages][benchmark]. In this article [Piotr Kołaczkowski][] used Chat GPT to

     

       15
       +
       generate the examples in the different languages and benchmarked them. This was

     

       16
       +
       poor choice as I have found this article and read the Elixir example:

       +
       ```elixir

     

       22
       +
       tasks =

     

       23
       +
           for _ <- 1..num_tasks do

     

       24

               Task.async(fn ->

     

       25

       32
       +
       And, well, it's pretty poor example of BEAM's process memory usage, and I am

     

       33
       +
       not talking about the fact that it uses 4 spaces for indentation.

       For 1 million processes this code reported 3.94 GiB of memory used by the process

     

       36
       +
       in Piotr's benchmark, but with little work I managed to reduce it about 4 times

     

       37
       +
       to around 0.93 GiB of RAM usage. In this article I will describe:

       +
       - how I did that

     

       40

       - why the original code was consuming so much memory

     

       41

       - why in the real world you probably should not optimise like I did here

       ## What are Erlang processes?

     

       46
       +
       

     

       47
       +
       Erlang is ~~well~~ known of being language which support for concurrency is

     

       48
       +
       superb, and Erlang processes are the main reason for that. But what are these?

     

       49
       +
       

     

       50
       +
       In Erlang *process* is the common name for what other languages call *virtual

     

       51
       +
       threads* or *green threads*, but in Erlang these have small neat twist - each of

     

       52
       +
       the process is isolated from the rest and these processes can communicate only

     

       53
       +
       via message passing. That gives Erlang processes 2 features that are rarely

     

       54
       +
       spotted in other implementations:

     

       55
       +
       

     

       56
       +
       - Failure isolation - bug, unhandled case, or other issue in single process will

     

       57
       +
         not directly affect any other process in the system. VM can send some messages

     

       58
       +
         due to process shutdown, and other processes may be killed because of that,

     

       59
       +
         but by itself shutting down single process will not cause problems in any

     

       60
       +
         process not related to that.

     

       61
       +
       - Location transparency - process can be spawned locally or on different

     

       62
       +
         machine, but from the viewpoint of the programmer, there is no difference.

     

       63
       +
       

     

       64
       +
       The above features and requirements results in some design choices, but for our

     

       65
       +
       purpose only one is truly needed today - each process have separate and (almost)

     

       66
       +
       independent memory stack from any other process.

     

       67
       +
       

     

       68
       +
       ### Process dictionary

     

       69
       +
       

     

       70
       +
       Each process in Erlang VM has dedicated *mutable* memory space for their

     

       71
       +
       internal uses. Most people do not use it for anything because in general it

     

       72
       +
       should not be used unless you know exactly what you are doing (in my case, a bad

     

       73
       +
       carpenter could count cases when I needed it, on single hand). In general it's

     

       74
       +
       *here be dragons* area.

     

       75
       +
       

     

       76
       +
       How it's relevant to us?

     

       77
       +
       

     

       78
       +
       Well, OTP internally uses process dictionary (`pdict` for short) to store

     

       79
       +
       metadata about given process that can be later used for debugging purposes. Some

     

       80
       +
       data that it store are:

     

       81
       +
       

     

       82
       +
       - Initial function that was run by the given process

     

       83
       +
       - PIDs to all ancestors of the given process

     

       84
       +
       

     

       85
       +
       Different processes abstractions (like `gen_server`/`GenServer`, Elixir's

     

       86
       +
       `Task`, etc.) can store even more metadata there, `logger` store process

     

       87
       +
       metadata in process dictionary, `rand` store state of the PRNGs in the process

     

       88
       +
       dictionary. it's used quite extensively by some OTP features.

     

       89
       +
       

     

       90
       +
       ### "Well behaved" OTP process

     

       91
       +
       

     

       92
       +
       In addition to the above metadata if the process is meant to be "well behaved"

     

       93
       +
       process in OTP system, i.e. process that can be observed and debugged using OTP

     

       94
       +
       facilities, it must respond to some additional messages defined by [`sys`][]

     

       95
       +
       module. Without that the features like [`observer`][] would not be able to "see"

     

       96
       +
       the content of the process state.

     

       97

       ## Process memory usage

     

       102
       +
       

     

       103
       +
       As we have seen above, the `Task.async/1` function form Elixir **must** do

     

       104
       +
       much more than just simple "start process and live with it". That was one of the

     

       105
       +
       most important problems with the original process, it was using system, that was

     

       106
       +
       allocating quite substantial memory alongside of the process itself, just to

     

       107
       +
       operate this process. In general, that would be desirable approach (as you

     

       108
       +
       **really, really, want the debugging facilities**), but in synthetic benchmarks,

     

       109
       +
       it reduce the feasibility of such benchmark.

     

       110
       +
       

     

       111
       +
       If we want to avoid that additional memory overhead in our spawned processes we

     

       112
       +
       need to go back to more primitive functions in Erlang, namely `erlang:spawn/1`

     

       113
       +
       (`Kernel.spawn/1` in Elixir). But that mean that we cannot use

     

       114
       +
       `Task.await_many/2` anymore, so we need to workaround it by using custom

     

       115
       +
       function:

     

       116
       +
       

     

       117
       +
       ```elixir

     

       118

       121

       122

       details in next section).

       ## All your lists are belongs to us now

     

       152
       +
       

     

       153
       +
       Erlang, like most of the functional programming languages, have 2 built-in

     

       154
       +
       sequence types:

     

       155
       +
       

     

       156
       +
       - Tuples - which are non-growable product type of the values, so you can access

     

       157
       +
         any field quite fast, but adding more values is performance no-no

     

       158
       +
       - (Singly) linked lists - growable type (in most case it will have single type

     

       159
       +
         values in it, but in Erlang that is not always the case), which is fast to

     

       160
       +
         prepend or pop data from the beginning, but do not try to do anything else if

     

       161
       +
         you care about performance.

     

       162
       +
       

     

       163
       +
       In this case we will focus on the 2nd one, as there tuples aren't important at

     

       164
       +
       all.

     

       165
       +
       

     

       166
       +
       Singly linked list is simple data structure. It's either special value `[]`

     

       167
       +
       (an empty list) or it's something called "cons-cell". Cons-cells are also

       simple structures - it's 2ary tuple (tuple with 2 elements) where first value

     

       169
       +
       is head - the value in the list cell, and another one is the "tail" of the list (aka

     

       170
       +
       rest of the list). In Elixir the cons-cell is denoted like that `[head | tail]`.

     

       171
       +
       Super simple structure as you can see, and perfect for the functional

     

       172
       +
       programming as you can add new values to the list without modifying existing

     

       173
       +
       values, so you can be immutable and fast. However if you need to construct the

     

       174
       +
       sequence of a lot of values (like our list of all tasks) then we have problem.

     

       175
       +
       Because Elixir promises that list returned from the `for` will be **in-order**

     

       176
       +
       of the values passed to it. That mean that we either need to process our data

     

       177
       +
       like that:

     

       178
       +
       

     

       179
       +
       ```elixir

     

       180
       +
       def map([], _), do: []

     

       181
       +
       

     

       182
       +
       def map([head | tail], func) do

     

       183
       +
         [func.(head) | map(tail, func)]

     

       184
       +
       end

     

       185
       +
       ```

     

       186
       +
       

     

       187
       +
       Where we build call stack (as we cannot have tail call optimisation there, of

     

       188
       +
       course sans compiler optimisations). Or we need to build our list in reverse

     

       189
       +
       order, and then reverse it before returning (so we can have TCO):

     

       190
       +
       

     

       191
       +
       ```elixir

     

       192
       +
       def map(list, func), do: do_map(list, func, [])

     

       193
       +
       

     

       194
       +
       def map([], _func, agg), do: :lists.reverse(agg)

     

       195

       196
       +
       def map([head | tail], func, agg) do

     

       197
       +
         map(tail, func, [func.(head) | agg])

     

       198

       +
       Which one of these approaches is more performant is irrelevant[^erlang-perf],

     

       202
       +
       what is relevant is that we need either build call stack or construct our list

     

       203
       +
       *twice* to be able to conform to the Elixir promises (even if in this case we do

     

       204
       +
       not care about order of the list returned by the `for`).

     

       205
       +
       

     

       206
       +
       [^erlang-perf]: Sometimes body recursion will be faster, sometimes TCO will be

     

       207
       +
       faster. it's impossible to tell without more benchmarking. For more info check

       210

       Of course we could mitigate our problem by using `Enum.reduce/3` function (or

     

       211
       +
       writing it on our own) and end with code like:

     

       212
       +
       

     

       213
       +
       ```elixir

     

       214

       215
       +
         def await(pid) when is_pid(pid) do

     

       216
       +
           ref = Process.monitor(pid)

     

       217

         end

           pid =

     

       232

       234

           [pid | agg]

       +
       Bench.await_many(tasks)

     

       238
       +
       ```

     

       239
       +
       

     

       240
       +
       Even then we build list of all PIDs.

     

       241
       +
       

     

       242
       +
       Here I can also go back to the "second problem* I have mentioned above.

     

       243
       +
       `Task.await_many/1` *also construct a list*. it's list of return value from all

     

       244
       +
       the processes in the list, so not only we constructed list for the tasks' PIDs,

     

       245
       +
       we also constructed list of return values (which will be `:ok` for all processes

     

       246
       +
       as it's what `:timer.sleep/1` returns), and immediately discarded all of that.

     

       247
       +
       

     

       248
       +
       How we can better? See that **all** we care is that all `num_task` processes

     

       249
       +
       have gone down. We do not care about any of the return values, all what we want

     

       250
       +
       is to know that all processes that we started went down. For that we can just

     

       251
       +
       send messages from the spawned processes and count the received messages count:

     

       252
       +
       

     

       253
       +
       ```elixir

     

       254
       +
       defmodule Bench do

     

       255
       +
         def worker(parent) do

     

       256
       +
           :timer.sleep(10000)

     

       257
       +
           send(parent, :done)

     

       258
       +
         end

     

       259
       +
       

     

       260
       +
         def start(0), do: :ok

     

       261
       +
         def start(n) when n > 0 do

     

       262
       +
           this = self()

     

       263
       +
           spawn(fn -> worker(this) end)

     

       264
       +
       

     

       265
       +
           start(n - 1)

     

       266
       +
         end

     

       267

         def await(0), do: :ok

     

       269
       +
         def await(n) when n > 0 do

     

       270
       +
           receive do

     

       271
       +
             :done -> await(n - 1)

     

       272
       +
           end

     

       273
       +
         end

     

       274
       +
       end

     

       275

       276
       +
       Bench.start(num_tasks)

     

       277
       +
       Bench.await(num_tasks)

     

       278
       +
       ```

     

       279
       +
       

     

       280
       +
       Now we do not have any lists involved and we still do what the original task

     

       281
       +
       meant to do - spawn `num_tasks` processes and wait till all go down.

     

       282
       +
       

     

       283
       +
       ## Arguments copying

     

       284
       +
       

     

       285
       +
       One another thing that we can account there - lambda context and data passing

     

       286
       +
       between processes.

     

       287
       +
       

     

       288
       +
       You see, we need to pass `this` (which is PID of the parent) to our newly

     

       289
       +
       spawned process. That is suboptimal, as we are looking for the way to reduce

     

       290
       +
       amount of the memory (and ignore all other metrics at the same time). As Erlang

     

       291
       +
       processes are meant to be "share nothing" type of processes there is problem -

     

       292
       +
       we need to copy that PID to all processes. it's just 1 word (which mean 8 bytes

     

       293
       +
       on 64-bit architectures, 4 bytes on 32-bit), but hey, we are microbenchmarking,

     

       294
       +
       so we cut whatever we can (with 1M processes, this adds up to 8 MiBs).

     

       295
       +
       

     

       296
       +
       Hey, we can avoid that by using yet another feature of Erlang, called

     

       297
       +
       *registry*. This is yet another simple feature that allows us to assign PID of

     

       298
       +
       the process to the atom, which allows us then to send messages to that process

     

       299
       +
       using just name, we have given. While atoms are also 1 word that wouldn't make

     

       300
       +
       sense to send it as well, but instead we can do what any reasonable

     

       301
       +
       microbenchmarker would do - *hardcode stuff*:

     

       302
       +
       

     

       303
       +
       ```elixir

       313
       +
       

     

       314
       +
           start(n - 1)

     

       315
       +
         end

     

       316

       +
         def await(0), do: :ok

         def await(n) when n > 0 do

     

       319

       320

             :done -> await(n - 1)

     

       321

           end

       +
         end

       Process.register(self(), :parent)

       327
       +
       Bench.start(num_tasks)

     

       328
       +
       Bench.await(num_tasks)

     

       329
       +
       ```

     

       330
       +
       

     

       331
       +
       Now we do not pass any arguments, and instead rely on the registry to dispatch

     

       332
       +
       our messages to respective processes.

     

       333
       +
       

     

       334
       +
       ## One more thing

     

       335
       +
       

     

       336
       +
       As you may have already noticed we are passing lambda to the `spawn/1`. That is

     

       337
       +
       also quite suboptimal, because of [difference between remote and local call][remote-vs-local].

     

       338
       +
       This mean that we are paying slight memory cost for these processes to keep the

     

       339
       +
       old module in memory. Instead we can use either fully qualified function capture

     

       340
       +
       or `spawn/3` function that accepts MFA (module, function name, arguments list)

     

       341
       +
       argument. We end with:

     

       342

       As we can see we have reduced the memory use by about 30% by just changing

     

       402
       +
       from `Task.async/1` to `spawn/1`. Further optimisations reduced memory usage

     

       403
       +
       slightly, but with no such drastic changes.

       Well, with some VM flags tinkering - of course.

       420
       +
       

     

       421
       +
       As we can see, there are 105 words that are required and 233 words which are

     

       422
       +
       used for preallocated heap. But this is microbenchmarking, so as we do not need

     

       423
       +
       that much of memory (because our processes basically does nothing), we can

     

       424
       +
       reduce it. We do not care about time performance anyway. For that we can use

     

       425
       +
       `+hms` flag and set it to some small value, for example `1`.

     

       426
       +
       

     

       427
       +
       In addition to heap size Erlang by default load some additional data from the

     

       428
       +
       BEAM files. That data is used for debugging and error reporting, but again, we

     

       429
       +
       are microbenchmarking, and who need debugging support anyway (answer: everyone,

     

       430
       +
       so **do not** do it in production). Luckily for us, the VM has yet another flag

     

       431
       +
       for that purpose `+L`.

     

       432
       +
       

     

       433
       +
       Erlang also uses some [ETS][] (Erlang Term Storage) tables by default (for

     

       434
       +
       example to support process registry we have mentioned above). ETS tables can be

     

       435
       +
       compressed, but by default it's not done, as it can slow down some kinds of

     

       436
       +
       operations on such tables. Fortunately there is, another, flag `+ec` that has

       ## Summary

     

       459
       +
       

     

       460
       +
       First of all:

     

       461
       +
       

     

       462
       +
       > Please, do not use ChatGPT for writing code for microbenchmarks.

     

       463
       +
       

     

       464
       +
       The thing about *micro*benchmarking is that we write code that does as little as

     

       465
       +
       possible to show (mostly) meaningless features of the given technology in

     

       466
       +
       abstract environment. ChatGPT cannot do that, not out of malice or incompetence,

     

       467
       +
       but because it used (mostly) *good* and idiomatic code to teach itself,

     

       468
       +
       microbenchmarks rarely are something that people will consider to have these

     

       469
       +
       qualities. It also cannot consider other features that [wetware][] can take into

     

       470
       +
       account (like our "we do not need lists there" thing).

       104
        
       

     

       105
        
       Just check [this out](/common-test-example/simple/index.html). This is example report

     

       106
        
       generated by the Common Test. As you can see it contains a lot of information in

     

       107
       -
       quite readable format. Not only it contains informations about current run, but

     

       108
        
       all previous runs as well, which is really handy when tracking regressions.

     

       109
        
       

     

       110

       logging facility it is completely possible to log your own informations during

     

       112

       tests, for example, lets modify our test to log some informations:

     

       113
        
       

     

       114

       In my new job I have opportunity to work a little bit more with Erlang code and

       103
        
       

     

       104
        
       Just check [this out](/common-test-example/simple/index.html). This is example report

     

       105
        
       generated by the Common Test. As you can see it contains a lot of information in

     

       106
       +
       quite readable format. Not only it contains information about current run, but

     

       107
        
       all previous runs as well, which is really handy when tracking regressions.

     

       108
        
       

     

       109
       +
       But can we store even more information there? Yes, as CT includes simple

     

       110
       +
       logging facility it is completely possible to log your own information during

     

       111
       +
       tests, for example, lets modify our test to log some information:

     

       112
        
       

     

       113
        
       ```erlang

       test_function_name(_Config) ->

       116

       118
        
       

     

       119
       +
       Now when we run tests again, then we will see more information (even coloured)

     

       120
        
       in [our test log](/common-test-example/log/ct_run.ct@NiunioBook.2019-07-16_11.03.21/common-test-example.log.logs/run.2019-07-16_11.03.22/example_suite.test_function_name.html):

       Some time ago, there was an anime available on Netflix — *Godzilla Singular

     

       10
       +
       Point*. It wasn't a spectacular success, but it featured a plot device that I

     

       11
       +
       think reflects something increasingly common today: you need to know the answer

     

       12
       +
       to your question before you can ask it.

     

       13
       +
       

     

       14
       +
       This is something I see all the time in the current wave of AI hype. You need to

     

       15
       +
       know what the answer *should* be before you can write a useful prompt.

     

       16

       19
       +
       The issue I have with many AI use cases is this: unless you have specialized

     

       20
       +
       knowledge about the topic you're asking about, you can't reliably tell the

     

       21
       +
       difference between a solid AI answer and complete nonsense.

     

       22
       +
       

     

       23
       +
       I've had a few discussions about this on various Discord servers. The example I

     

       24
       +
       often use is this simple question posed to an AI:

     

       25
       +
       

     

       26
       +
       > Does 6 character long identification number, that contains digits and upper

     

       27
       +
       > case letters (with exception to 0, O, 1, I, and L) is enough to randomly

     

       28
       +
       > assign unique identification numbers for 10 million records?

     

       29
       +
       

     

       30
       +
       You can see for your self answer from ChatGPT [there][chatgpt].

     

       31
       +
       

     

       32
       +
       At first glance, the answer looks valid and sensible. The math checks out. It

     

       33
       +
       calculates the number of available combinations correctly. Everything seems

     

       34
       +
       *fine*.

     

       35
       +
       

     

       36
       +
       **BUT…**

     

       37
       +
       

     

       38
       +
       There is huge issue there, and probably most of the people who have been working

     

       39
       +
       with basic statistic or cryptography will notice it. ChatGPT (and any other AI

     

       40
       +
       that I have tested out) fail to notice very important word there

     

       41
       +
       

     

       42
       +
       > \[…] randomly \[…]

     

       43
       +
       

     

       44
       +
       This single word invalidates the entire reasoning, despite the correct

     

       45
       +
       calculations. Because of the [birthday problem][], the answer isn't feasible.

     

       46
       +
       While it's technically possible to assign a unique ID to every record, doing so

     

       47
       +
       randomly introduces a high probability of collisions.

     

       48
       +
       

     

       49
       +
       - At around 35,000 generated IDs, there's already a 50% chance of a collision

     

       50
       +
       - At around 90,000, the chance of at least one duplicate reaches 99%

     

       51
       +
       

     

       52
       +
       So even though the math is correct, the logic fails under the randomness constraint.

       This is my main issue with AI tools: if you already have knowledge about the

     

       57
       +
       subject, you don’t really need to ask the AI. But if you don’t have that

     

       58
       +
       knowledge, you have no reliable way of knowing whether the answer makes sense or

     

       59
       +
       not. It’s like playing *Jeopardy!* — you need to know the answer before you can

     

       60
       +
       phrase the right question.

     

       61
       +
       

     

       62
       +
       In my view, AI is most useful in areas where the results can be quickly reviewed

     

       63
       +
       and discarded if needed. That’s why the whole “vibe coding” (aka slop

     

       64
       +
       generation) approach falls short. If you don’t have a good sense of what the

     

       65
       +
       output should look like, you probably don’t have the expertise to verify it.

       ## Abstract

     

       29
       +
       

     

       30
       +
       Most of the operating systems are multi-process and multi-user operating

     

       31
       +
       systems. This has a lot of positive aspects, like to be able to do more than one

     

       32
       +
       thing at the time at our devices, but it introduces a lot of complexities that

     

       33
       +
       in most cases are hidden from the users and developers. These things still need

     

       34
       +
       to be handled in one or another way. The most basic problems are:

     

       35
       +
       

     

       36
       +
       - some processes need to be started before user can interact with the OS

     

       37
       +
         in meaningful (for them) way (for example mounting filesystems, logging,

     

       38
       +
         etc.)

     

       39
       +
       - some processes require strict startup ordering, for example you may need

     

       40
       +
         logging to be started before starting HTTP server

     

       41
       +
       - system operator somehow need to know when the process is ready to do their

     

       42
       +
         work, which is often some time after process start

     

       43
       +
       - system operator should be able to check process state in case when debugging

     

       44
       +
         is needed, most commonly via logs

     

       45
       +
       - shutdown of the processes should be handled in a way, that will allow other

     

       46
       +
         processes to be shut down cleanly (for example application that uses DB should

     

       47
       +
         be down before DB itself)

     

       48
       +
       

     

       49
       +
       ## Why we need system supervisor?

     

       50
       +
       

     

       51
       +
       System supervisor is a process started early in the OS boot, that should handle

     

       52
       +
       starting and managing all other processes that will be run on our system. It is

     

       53
       +
       often the init process (first process started by the OS that is running with PID

     

       54
       +
       1\) or it is first (and sometimes only) process started by the init process.

     

       55
       +
       Popular examples of such supervisors (often integrated with init systems):

     

       56
       +
       

     

       57
       +
       - SysV which is "traditional" implementation that originates at UNIX System

     

       58
       +
         V (hence the name)

     

       59
       +
       - BSD init that with some variations is used in BSD-based OSes (NetBSD,

     

       60
       +
         FreeBSD), it shares some similarities to SysV init and services description is

     

       61
       +
         provided by shell scripts

     

       62
       +
       - OpenRC that also uses shell-based scripts for service description, used by

     

       63
       +
         Linux distributions like Gentoo or Alpine

     

       64
       +
       - `launchd` that is used on Darwin (macOS, iPadOS, iOS, watchOS) systems that uses

     

       65
       +
         XML-based `plists` for services description

     

       66
       +
       - `runit` which is small init and supervisor, but quite capable, for example

     

       67
       +
         used by Void Linux

     

       68
       +
       - Upstart created by Canonical Ltd. as a replacement for SysV-like init system

     

       69
       +
         in Ubuntu (no longer in use in Ubuntu), still used in some distributions like

     

       70
       +
         ChromeOS or Synology NAS

     

       71
       +
       - `systemd` (this is the name, not "SystemD") that was created by Red Hat

     

       72
       +
         employee, (in)famous Lennart Poettering, and later was adopted by almost all

     

       73
       +
         major Linux distributions which spawned some heated discussion about it

     

       74
       +
       

     

       75
       +
       In this article I will focus on systemd, and its approach to "new-style system

     

       76
       +
       daemons".

       **DISCLAIMER**

     

       81
       +
       

     

       82
       +
       Each of the solutions mentioned above has its strong and weak points. I do not

     

       83
       +
       want to start another flame war whether it is good or not. It has some good in

     

       84
       +
       it, and it has some bad in it, but we can say that it "won" over the most used

     

       85
       +
       distributions, and despite our love or hate towards it, we need to learn how to

     

       86
       +
       live with that.

       +
       ## Why `systemd`?

     

       91
       +
       

     

       92
       +
       `systemd` became a thing because SysV approach to ordering services' startup was

     

       93
       +
       mildly irritating and non-parallelizable. In short, SysV is starting processes

     

       94
       +
       exactly in lexicographical order of files in given directory. This meant, that

     

       95
       +
       even if your service didn't need the DB at all, but it somehow ended further in

     

       96
       +
       the directory listing, you ended in waiting for the DB startup. Additionally,

     

       97
       +
       SysV wasn't really monitoring services, it just assumed that when process forked

     

       98
       +
       itself to the background, then it is "done" with the startup, and we can

     

       99
       +
       continue. This is obviously not true in many cases, for example, if your

     

       100
       +
       previous shutdown wasn't clean because of power shortage or other issue, then

     

       101
       +
       your DB probably need a bit of time to rebuild state from journal. This causes

     

       102
       +
       even more slowdown for the processes further in the list. This is highly

     

       103
       +
       undesired in modern, cloud-based, environment, where you can often start the

     

       104
       +
       machines on-demand during autoscaling actions. When there is a spike in the

     

       105
       +
       traffic that need autoscaling, then the sooner new machine is in usable state

     

       106
       +
       the sooner it can take load from other machines.

     

       107
       +
       

     

       108
       +
       Different tools take different approach to solve that issue there. `systemd`

     

       109
       +
       take approach that is derived from `launchd` - do not do stuff, that is not

     

       110
       +
       needed. We can trigger on action of other services (obviously), but also on

     

       111
       +
       stuff like socket activity, path creation/modification, mounts, connection or

     

       112
       +
       disconnection of device, time events, etc.

     

       113
       +
       

     

       114
       +
       ---

     

       115
       +
       

     

       116
       +
       **DIGRESSION**

     

       117
       +
       

     

       118
       +
       This is exactly the reason why `systemd` has its infamous "feature creep", it

     

       119
       +
       doesn't "digest" all services like Cron or `udev`. It is not that these are

     

       120
       +
       "tightly" intertwined into `systemd`. You can still replace them with their

     

       121
       +
       older counterparts, you will just lose all the features these bring with them.

     

       122
       +
       

     

       123
       +
       ---

     

       124
       +
       

     

       125
       +
       Such lazy approach sometimes require changes into the service itself. For

     

       126
       +
       example to let supervisor know, that you are ready (not just started), you need

     

       127
       +
       some way to communicate with supervisor. In `systemd` you can do so via UNIX

     

       128
       +
       socket pointed by `NOTIFY_SOCKET` environment variable passed to your

     

       129
       +
       application. With the same socket you can implement another useful feature

     

       130
       +
       \- watchdog/heartbeat process. This mean that if for any reason your process

     

       131
       +
       became non-responsive (but it will refuse to die), then supervisor will

     

       132
       +
       forcefully bring process down and restart it, assuming that the error was

     

       133
       +
       accidental.

     

       134
       +
       

     

       135
       +
       About restarting, we can define behaviour of service after main process die. It

     

       136
       +
       can be restarted regardless of the exit code, it can be restarted on abnormal

     

       137
       +
       exit, it can remain shut, etc. Does this ring a bell? This works similarly to

     

       138
       +
       OTP supervisors, but "one level above". If your service utilize system

     

       139
       +
       supervisor right, you can make your application almost ultimately self-healing

     

       140
       +
       (by restarts).

     

       141

       ## Basic setup

     

       143
       +
       

     

       144
       +
       Now, when we know a little about how and why `systemd` works as it works, we

     

       145
       +
       now can go to details on how to utilize that with services in Elixir.

     

       146
       +
       

     

       147
       +
       As a base we will implement super simple Plug application:

     

       148
       +
       

     

       149
       +
       ```elixir

     

       150
       +
       # hello/application.ex

     

       151
       +
       defmodule Hello.Application do

     

       152
       +
         use Application

     

       153
       +
       

     

       154
       +
         def start(_type, _opts) do

     

       155
       +
           children = [

     

       156
       +
             {Plug.Cowboy, [scheme: :http, plug: Hello.Router] ++ cowboy_opts()},

     

       157
       +
             {Plug.Cowboy.Drainer, refs: :all}

     

       158
       +
           ]

     

       159
       +
       

     

       160
       +
           Supervisor.start_link(children, strategy: :one_for_one)

     

       161
       +
         end

     

       162
       +
       

     

       163
       +
         defp cowboy_opts do

     

       164
       +
           [

     

       165
       +
             port: String.to_integer(System.get_env("PORT", "4000"))

     

       166
       +
           ]

     

       167
       +
         end

     

       168
       +
       end

     

       169
       +
       ```

     

       170
       +
       

     

       171
       +
       ```elixir

     

       172
       +
       # hello/router.ex

     

       173
       +
       defmodule Hello.Router do

     

       174
       +
         use Plug.Router

     

       175
       +
       

     

       176
       +
         plug :match

     

       177
       +
         plug :dispatch

     

       178
       +
       

     

       179
       +
         get "/" do

     

       180
       +
           send_resp(conn, 200, "Hello World!")

     

       181
       +
         end

     

       182
       +
       end

     

       183
       +
       ```

     

       184
       +
       

     

       185
       +
       I will also assume that we are using [Mix release][mix-release] named `hello`

     

       186
       +
       that we later copy to `/opt/hello`.

     

       187
       +
       

     

       188
       +
       [mix-release]: https://hexdocs.pm/mix/Mix.Tasks.Release.html

     

       189
       +
       

     

       190
       +
       ### systemd unit file

     

       191
       +
       

     

       192
       +
       We have only one thing left, we need to define our [`hello.service`][systemd.service]:

     

       193
       +
       

     

       194
       +
       ```ini

     

       195
       +
       [Unit]

     

       196
       +
       Description=Hello World service

     

       197
       +
       

     

       198
       +
       [Service]

     

       199
       +
       Environment=PORT=80

     

       200
       +
       ExecStart=/opt/hello/bin/hello start

     

       201
       +
       ```

     

       202
       +
       

     

       203
       +
       Now you can create file with that content in

     

       204
       +
       `/usr/local/lib/systemd/system/hello.service` and then start it with:

     

       205
       +
       

     

       206
       +
       ```

     

       207
       +
       # systemctl start hello.service

     

       208
       +
       ```

     

       209
       +
       

     

       210
       +
       This is the simplest service imaginable, however from the start we have few

     

       211
       +
       issues there:

     

       212
       +
       

     

       213
       +
       - It will run service as user running supervisor, so if it is run using global

     

       214
       +
         supervisor, then it will run as `root`. You do not want to run anything as

     

       215
       +
         `root`.

     

       216
       +
       - On error it will produce (BEAM) core dump, which may contain sensitive data.

     

       217
       +
       - It can read (and, due to being run as `root`, write) everything in the system,

     

       218
       +
         like private data of other processes.

     

       219
       +

       ## Service readiness

     

       223
       +
       

     

       224
       +
       Erlang VM isn't really the best tool out there wrt the startup times. In

     

       225
       +
       addition to that our application may need some preparation steps before it can

     

       226
       +
       be marked as "ready". This is problem that I sometimes encounter in Docker,

     

       227
       +
       where some containers do not really have any health check, and then I need to

     

       228
       +
       have loop with check in some of the containers that depend on another one. This

     

       229
       +
       "workaround" is frustrating, error prone, and can cause nasty Heisenbugs when

     

       230
       +
       the timing will be wrong.

     

       231
       +
       

     

       232
       +
       Two possible solutions for this problem are:

     

       233
       +
       

     

       234
       +
       - Readiness probe - another program that is ran after the main process is

     

       235
       +
         started, that checks whether our application is ready to work.

     

       236
       +
       - Notification system where our application uses some common protocol to inform

     

       237
       +
         the supervisor that it finished setup and is ready for work.

     

       238
       +
       

     

       239
       +
       systemd supports the second approach via [`sd_notify`][sd_notify]. The approach

     

       240
       +
       there is simple - we have `NOTIFY_SOCKET` environment variable that contain path

     

       241
       +
       to the Unix datagram socket, that we can use to send information about state of

     

       242
       +
       our application. This socket accept set of different messages, but right now,

     

       243
       +
       for our purposes, we will focus only on few of them:

     

       244
       +
       

     

       245
       +
       - `READY=1` - marks our service as ready, aka it is ready to do its work (for

     

       246
       +
         example accept incoming HTTP connections in our example). It need to be sent

     

       247
       +
         within given timespan after start of the VM, otherwise the process will be

     

       248
       +
         killed and possibly restarted

     

       249
       +
       - `STATUS=name` - sets status of our application that can be checked via

     

       250
       +
         `systemctl status hello.service`, this allows us to have better insight into

     

       251
       +
         what is the high level state without manually traversing through logs

     

       252
       +
       - `RELOADING=1` - marks, that our application is reloading, which in general may

     

       253
       +
         mean a lot of things, but there it will be used to mark `:init.restart/0`-like

     

       254
       +
         behaviour (due to [erlang/otp#4698][] there is wrapper for that function in

     

       255
       +
         `systemd` library). The process need then to send `READY=1` within given

     

       256
       +
         timespan, or the process will be marked as a malfunctioning, and will be

     

       257
       +
         forcefully killed and possibly restarted

     

       258
       +
       - `STOPPING=1` - marks, that our application began shutting down process, and

     

       259
       +
         will be closing soon. If the process will not close within given timespan, it

     

       260
       +
         will be forcefully killed

     

       261
       +
       

     

       262
       +
       These messages provide us enough power to not only mark the service as ready,

     

       263
       +
       but also provides additional information about system state, so even operator,

     

       264
       +
       who knows a little about Erlang or our application runtime, will be able to

     

       265
       +
       understand what is going on.

     

       266
       +
       

     

       267
       +
       The main thing is that systemd will wait with activation of the dependants of

     

       268
       +
       our system as well as the `systemctl start` and `systemctl restart` commands

     

       269
       +
       will wait until our service declare that it is ready.

     

       270
       +
       

     

       271
       +
       Usage of such feature is quite simple:

     

       272
       +
       

     

       273
       +
       ```ini

     

       274
       +
       [Unit]

     

       275
       +
       Description=Hello World service

     

       276
       +
       

     

       277
       +
       [Service]

     

       278
       +
       # Define `Type=` to `notify`

     

       279
       +
       Type=notify

     

       280
       +
       Environment=PORT=80

     

       281
       +
       ExecStart=/opt/hello/bin/hello start

     

       282
       +
       WatchdogSec=1min

     

       283
       +
       ```

     

       284
       +
       

     

       285
       +
       And then in our supervisor tree we need add `:systemd.ready()` **after** last

     

       286
       +
       process needed for proper functioning of our application, in our simple example

     

       287
       +
       it is after `Plug.Cowboy`:

     

       288
       +
       

     

       289
       +
       ```elixir

     

       290
       +
       # hello/application.ex

     

       291
       +
       defmodule Hello.Application do

     

       292
       +
         use Application

     

       293
       +
       

     

       294
       +
         def start(_type, _opts) do

     

       295
       +
           children = [

     

       296
       +
             {Plug.Cowboy, [scheme: :http, plug: Hello.Router] ++ cowboy_opts()},

     

       297
       +
             :systemd.ready(), # <-- it is function call, as it returns proper

     

       298
       +
                               # `child_spec/0`

     

       299
       +
             {Plug.Cowboy.Drainer, refs: :all}

     

       300
       +
           ]

     

       301
       +
       

     

       302
       +
           Supervisor.start_link(children, strategy: :one_for_one)

     

       303
       +
         end

     

       304
       +
       

     

       305
       +
         defp cowboy_opts do

     

       306
       +
           [

     

       307
       +
             port: String.to_integer(System.get_env("PORT", "4000"))

     

       308
       +
           ]

     

       309
       +
         end

     

       310
       +
       end

     

       311
       +
       ```

     

       312
       +
       

     

       313
       +
       Now restarting our service will not finish immediately, but will wait until our

     

       314
       +
       service will declare that it is ready.

     

       315
       +
       

     

       316
       +
       ```

     

       317
       +
       # systemctl restart hello.service

     

       318
       +
       ```

     

       319
       +
       

     

       320
       +
       About `STOPPING=1` - the magic thing is that the `systemd` library takes care of

     

       321
       +
       it for you. As soon as the system will be scheduled to shutdown this message

     

       322
       +
       will be automatically sent, and the operator will be notified about this fact.

     

       323
       +
       

     

       324
       +
       We can also provide more information about state of our application. As you may

     

       325
       +
       have already noticed, we have [`Plug.Cowboy.Drainer`][] there. It is process that

     

       326
       +
       will delay shutdown of our application while there are still open connections.

     

       327
       +
       This can take some time, so it would be handy if the operator would see that the

     

       328
       +
       draining is in progress. We can easily achieve that by again changing our

     

       329
       +
       supervision tree to:

       ## Watchdog

     

       387
       +
       

     

       388
       +
       Watchdog allows us to monitor our application for responsiveness (as mentioned

     

       389
       +
       above). It is simple feature that requires our application to ping systemd

     

       390
       +
       within specified interval, otherwise the application will be forcibly shut down

     

       391
       +
       as malfunctioning. Fortunately for us, the `systemd` library that provides our

     

       392
       +
       integration, have that feature out of the box, so all we need to do to achieve

     

       393
       +
       expected result is set `WatchdogSec=` option in our `systemd.service` file:

     

       394
       +
       

     

       395
       +
       ```ini

     

       396
       +
       [Unit]

     

       397
       +
       Description=Hello World service

     

       398
       +
       

     

       399
       +
       [Service]

     

       400
       +
       Environment=PORT=80

     

       401
       +
       Type=notify

     

       402
       +
       ExecStart=/opt/hello/bin/hello start

     

       403
       +
       WatchdogSec=1min

     

       404
       +
       ```

     

       405
       +
       

     

       406
       +
       This configuration says that if the VM will not send healthy message each 1

     

       407
       +
       minute interval, then the service will be marked as malfunctioning. From the

     

       408
       +
       application side we can manage state of the watchdog in several ways:

     

       409
       +
       

     

       410
       +
       - By setting `systemd.watchdog_check` configuration option we can configure the

     

       411
       +
         function that will be called on each check, if that function return `true`

     

       412
       +
         then it mean that application is healthy and the systemd should be notified

     

       413
       +
         with ping, if it returns `false` or fail, then the check will be omitted.

     

       414
       +
       - Manually sending trigger message in case of detected problems via

     

       415
       +
         `:systemd.watchdog(trigger)`, it will immediately mark service as

     

       416
       +
         malfunctioning and will trigger action defined in service unit file (by

     

       417
       +
         default it will restart application)

     

       418
       +
       - Disabling built in watchdog process via `:systemd.watchdog(:disable)` and then

     

       419
       +
         manually sending `:systemd.watchdog(:ping)` within expected intervals

     

       420
       +
         (discouraged)

     

       421
       +
       

     

       422
       +
       ## Security

     

       423
       +
       

     

       424
       +
       We should start with changing default user and group which is assigned to our

     

       425
       +
       process. We can do so in 2 different ways:

     

       426
       +
       

     

       427
       +
       1. Use some existing user and group by defining `User=` and `Group=` directives

     

       428
       +
          in our service definition; or

     

       429
       +
       2. Create ephemeral user on-demand before our service starts, by using directive

     

       430
       +
         `DynamicUser=true` in service definition.

     

       431
       +
       

     

       432
       +
       I prefer second option, as it additionally provides a lot of other security

     

       433
       +
       related options, like creating private `/tmp` directory, making system

     

       434
       +
       read-only, etc. This has also some disadvantages, like removing all of given

     

       435
       +
       data on service shutdown, however there are options to keep some data between

     

       436
       +
       launches.

     

       437
       +
       

     

       438
       +
       In addition to that we can add `PrivateDevices=true` that will hide all

     

       439
       +
       physical devices from `/dev` leaving only pseudo devices like `/dev/null` or

     

       440
       +
       `/dev/urandom` (so you will be able to use `:crypto` and `:ssl` modules without

     

       441
       +
       problems).

     

       442
       +
       

     

       443
       +
       Next thing is that we can do, is to [disable crash dumps generated by BEAM][crash].

     

       444
       +
       While not strictly needed in this case, it is worth remembering, that it isn't

     

       445
       +
       hard to achieve, just use `Environment=ERL_CRASH_DUMP_SECONDS=0`.

     

       446
       +
       

     

       447
       +
       Our new, more secure, `hello.service` will look like:

     

       448
       +
       

     

       449

       Requires=network.target

       460
       +
       # We need to add capability to be able to bind on port 80

     

       461
       +
       CapabilityBoundingSet=CAP_NET_BIND_SERVICE

     

       462
       +
       

     

       463
       +
       # Hardening

     

       464
       +
       DynamicUser=true

     

       465
       +
       PrivateDevices=true

     

       466
       +
       Environment=ERL_CRASH_DUMP_SECONDS=0

     

       467
       +
       ```

     

       468
       +
       

     

       469
       +
       The problem with that configuration is that our service is now capable on

     

       470
       +
       binding **any** port under 1024, so for example, if there is some security

     

       471
       +
       issue, then the malicious party can open any of the restricted ports and then

     

       472
       +
       serve whatever data they want there. This can be quite problematic, and the

     

       473
       +
       solution for that problem will be covered in Part 2, where we will cover socket

     

       474
       +
       passing and socket activation for our service.

     

       475
       +
       

     

       476
       +
       With that we achieved quite basic level of isolation to what Docker (or other

     

       477
       +
       container runtime) is providing, but it do not require `overlayfs` or anything

     

       478
       +
       more, than what you already have on your machine. That means, updates done by

     

       479
       +
       your system package manager will be applied to all running services. With that

     

       480
       +
       you do not need to rebuild all your containers when there is security patch

     

       481
       +
       issued for any of your dependencies.

     

       482
       +
       

     

       483
       +
       Of course it only scratches the surface of what is possible with systemd wrt

     

       484
       +
       the hardening of the services. More information can be found in [RedHat

     

       485
       +
       article][rh-systemd-hardening] and in [`systemd-analyze security` command

     

       486
       +
       output][systemd-analyze-security]. Possible features are:

     

       487
       +
       

     

       488
       +
       - creation of the private networks for your services

     

       489
       +
       - disallowing creation of socket connections that are outside of the specified

     

       490
       +
         set of families

     

       491
       +
       - make only some paths readable

     

       492
       +
       - hide some paths from the process

     

       493
       +
       - etc.

       We already have our super simple service description. Just to refresh your

     

       30
       +
       memory, it is the `hello.service` file once again:

       +
       

     

       52
       +
       However there is one small problem. It allows our service to listen on **any**

     

       53
       +
       restricted port, not just `80` that we want to listen on. This can be

     

       54
       +
       troublesome as an attacker that gains RCE on our server can then capture any

     

       55
       +
       traffic on any port that we do not want to open (for example exposing port 22

     

       56
       +
       using the [`ssh`] module).

     

       57
       +
       

     

       58
       +
       It would be nice if we could somehow inject sockets for only the ports we want

     

       59
       +
       to listen to into our application.

     

       60
       +
       

     

       61
       +
       ## Socket passing

     

       62
       +
       

     

       63
       +
       Thanks to the [`systemd.socket`][systemd.socket] feature we can achieve that

     

       64
       +
       with a little work on our side.

     

       65
       +
       

     

       66
       +
       First we need to create new unit named `hello.socket` next to our

     

       67
       +
       `hello.service`:

     

       68
       +
       

     

       69
       +
       ```ini

     

       70
       +
       [Unit]

     

       71
       +
       Description=Listening socket

     

       72
       +
       Requires=sockets.target

     

       73
       +
       

     

       74
       +
       [Socket]

     

       75
       +
       ListenStream=80

     

       76
       +
       BindIPv6Only=both

     

       77
       +
       ReusePort=true

     

       78
       +
       NoDelay=true

     

       79
       +
       ```

     

       80
       +
       

     

       81
       +
       It will create a socket connected to TCP 80 (because we used `ListenStream=`,

     

       82
       +
       and TCP is the stream protocol). By default it will bind that socket to a

     

       83
       +
       service named the same as our socket, so now we need to edit our `hello.service`

     

       84
       +
       a little bit:

     

       85
       +
       

     

       86
       +
       ```ini

       Requires=network.target

       +
       WatchdogSec=1min

     

       96
       +
       

     

       97
       +
       # See, we no longer need to insecurely allow binding to any port

     

       98
       +
       # CapabilityBoundingSet=CAP_NET_BIND_SERVICE

     

       99
       +

       +
       # Hardening

     

       101
       +

       105
       +
       

     

       106
       +
       And we need to modify our `Hello.Application.cowboy_opts/0` to handle the socket

     

       107
       +
       which is passed to us a file descriptor:

             port: 0,     # (2)

     

       145

       148
       +
       end

     

       149
       +
       ```

     

       150
       +
       

     

       151
       +
       1. Systemd sockets are IPv6 enabled (we explicitly said that we want to listen

     

       152
       +
          on both). That means, that we need to mark our connection as an INET6

     

       153
       +
          connection. This will not affect IPv4 (INET) connections.

     

       154
       +
       1. We are required to pass `:port` key, but its value will be ignored, so we

     

       155
       +
          just pass `0`.

     

       156
       +
       1. We pass the file descriptor that will be then passed to the Cowboy listener.

     

       157
       +
       

     

       158
       +
       Now when we will start our service:

     

       159
       +
       

     

       160
       +
       ```txt

     

       161
       +
       # systemctl start hello.service

     

       162
       +
       ```

     

       163
       +
       

     

       164
       +
       It will be available at `https://localhost/` while still running as an

     

       165
       +
       unprivileged user.

     

       166
       +
       

     

       167
       +
       ### Multiple ports

     

       168
       +
       

     

       169
       +
       The question may arise - how to allow our service to listen on more than one

     

       170
       +
       port, for example you want to have your website available as HTTPS alongside

     

       171
       +
       "regular" HTTP. This means that our application needs to listen on two

     

       172
       +
       restricted ports:

     

       173
       +
       

     

       174
       +
       - 80 - for HTTP

     

       175
       +
       - 443 - for HTTPS

     

       176
       +
       

     

       177
       +
       Now we need to slightly modify a little our socket service and add another one.

     

       178
       +
       First rename our `hello.socket` to `hello-http.socket` and add a line

     

       179
       +
       `Service=hello.service` and `FileDescriptorName=http` to `[Socket]` section, so

     

       180
       +
       we end with:

     

       181
       +
       

     

       182

       199
       +
       Next we create a similar file, but for HTTPS named `hello-https.socket`

     

       200
       +
       

     

       201

       +
       Requires=sockets.target

     

       205
       +
       

     

       206
       +
       [Socket]

     

       207
       +
       FileDescriptorName=https

     

       208
       +
       ListenStream=443

     

       209
       +
       Service=hello.service

     

       210
       +
       BindIPv6Only=both

     

       211
       +
       ReusePort=true

     

       212
       +
       NoDelay=true

     

       213
       +
       ```

     

       214
       +
       

     

       215
       +
       And we add the dependency on both of our sockets to the `hello.service`:

     

       216
       +
       

     

       217
       +
       ```ini

       Description=Hello World service

     

       220
       +
       After=hello-http.socket hello-https.socket

     

       221
       +
       BindTo=hello-http.socket hello-https.socket

     

       222
       +
       

     

       223
       +
       [Service]

     

       224
       +
       ExecStart=/opt/hello/bin/hello start

     

       225
       +
       

     

       226
       +
       # Hardening

     

       227
       +
       DynamicUser=true

     

       228

       +
       Environment=ERL_CRASH_DUMB_SECONDS=0

     

       230
       +
       ```

     

       231
       +
       

     

       232
       +
       Now we need to somehow differentiate between our sockets in the

     

       233
       +
       `Hello.Application`, so we will be able to pass the proper FD to each of the

     

       234
       +
       listeners. The `:systemd.listen_fds/0` will return a list of file descriptors,

     

       235
       +
       and if they are named, the format will be a 2-tuple where the first element is

     

       236
       +
       the file descriptor and the second is the name as a string:

     

       237

       287

       Now our application will listen on both - HTTP and HTTPS, despite running as

     

       288
       +
       unprivileged user.

     

       289

       290
       +
       ## Socket activation

     

       291
       +
       

     

       292
       +
       Now, that we can inject sockets to our application with ease we can achieve even

     

       293
       +
       more fascinating feature - socket activation.

     

       294
       +
       

     

       295
       +
       Some of you may used `inetd` in the past, that allows you to dynamically start

     

       296
       +
       processes on network requests. It is quite an interesting tool that detects

     

       297
       +
       traffic on certain ports, then spawns a new process to handle it, passing data

     

       298
       +
       to and from that process via `STDIN` and `STDOUT`. There was a quirk though, it

     

       299
       +
       required the spawned process to shutdown after it handled the request and it was

     

       300
       +
       starting a new instance for each request. That works poorly with VMs like BEAM

     

       301
       +
       that have substantial startup time and are expected to be long-running systems.

     

       302
       +
       BEAM is capable of handling network requests on it's own.

     

       303
       +
       

     

       304
       +
       Fortunately for us, the way that we have implemented our systemd service is all

     

       305
       +
       that we need to have our application dynamically activated. To observe that we

     

       306
       +
       just need to shutdown everything:

     

       307
       +
       

     

       308
       +
       ```txt

     

       309
       +
       # systemctl stop hello-http.socket hello-https.socket hello.service

     

       310
       +
       ```

     

       311
       +
       

     

       312
       +
       And now relaunch **only the sockets**:

     

       313
       +
       

     

       314
       +
       ```txt

     

       315
       +
       # systemctl start hello-http.socket hello-https.socket

     

       316
       +
       ```

     

       317
       +
       

     

       318
       +
       We can check, that our service is not running:

     

       319
       +
       

     

       320
       +
       ```txt

     

       321

       327
       +
       

     

       328
       +
       We can see the `TriggeredBy` section that tells us, that this service will be

     

       329
       +
       started by one of the sockets listed there. Let see what will happen when we

     

       330
       +
       will try to request anything from our application:

     

       331
       +
       

     

       332
       +
       ```txt

     

       333

       336
       +
       

     

       337
       +
       You can see that we got a response from our application. This mean that our

     

       338
       +
       application must have started, and indeed when we check:

       still can be activated by our sockets:

     

       356

       357

       363

       That means, that systemd is still listening on the sockets that we defined, even

     

       364

       when our application is down, and will start our application again as soon as

       there are any incoming requests.

       Our application got launched again, automatically, just by the fact that

       It seems so. Independently of which port we try to reach our application on, it

     

       397

       will be automatically launched for us and the connection will be properly

       This post was created for myself to codify some basic guides that I use while

     

       15
       +
       writing tests. If you, my dear reader, read this then there is one important

     

       16
       +
       thing for you to remember:

     

       17
       +
       

     

       18
       +
       These are **guides** not *rules*. Each code base is different deviations and are

     

       19
       +
       expected and *will* happen. Just use the thing between your ears.

       ## `@subject` module attribute for module under test

     

       22
       +
       

     

       23
       +
       While writing test in Elixir it is not always obvious what we are testing. Just

     

       24
       +
       imagine test like:

     

       25
       +
       

     

       26
       +
       ```elixir

     

       27
       +
       test "foo should frobnicate when bar" do

     

       28
       +
         bar = pick_bar()

     

       29
       +
       

     

       30
       +
         assert :ok == MyBehaviour.foo(MyImplementation, bar)

     

       31
       +
       end

     

       32
       +
       ```

     

       33
       +
       

     

       34
       +
       It is not obvious at the first sight what we are testing. And it is pretty

     

       35
       +
       simplified example, in real world it can became even harder to notice what is

     

       36
       +
       module under test (MUT).

     

       37
       +
       

     

       38
       +
       To resolve that I came up with a simple solution. I create module attribute

     

       39
       +
       named `@subject` that points to the MUT:

     

       40
       +
       

     

       41
       +
       ```elixir

     

       42
       +
       @subject MyImplementation

     

       43
       +
       

     

       44
       +
       test "foo should frobnicate when bar" do

     

       45
       +
         bar = pick_bar()

     

       46
       +
       

     

       47
       +
         assert :ok == MyBehaviour.foo(@subject, bar)

     

       48
       +
       end

     

       49
       +
       ```

     

       50
       +
       

     

       51
       +
       Now it is more obvious what is MUT and what is just wrapper code around it.

     

       52
       +
       

     

       53
       +
       In the past I have been using `alias` with `:as` option, like:

     

       54
       +
       

     

       55
       +
       ```elixir

     

       56
       +
       alias MyImplementation, as: Subject

     

       57
       +
       ```

     

       58
       +
       

     

       59
       +
       However I find module attribute to be more visually outstanding and make it

     

       60
       +
       easier for me to notice `@subject` than `Subject`. But your mileage may vary.

     

       61
       +
       

     

       62
       +
       ## `describe` with function name

     

       63
       +
       

     

       64
       +
       That one is pretty basic, and I have seen that it is pretty standard for people:

     

       65
       +
       when you are writing tests for module functions, then group them in `describe`

     

       66
       +
       blocks that will contain name (and arity) of the function in the name. Example:

     

       67
       +
       

     

       68
       +
       ```elixir

     

       69
       +
       # Module under test

     

       70
       +
       defmodule Foo do

     

       71
       +
         def a(x, y, z) do

     

       72
       +
           # some code

     

       73
       +
         end

     

       74
       +
       end

     

       75
       +
       

     

       76
       +
       # Tests

     

       77
       +
       defmodule FooTest do

     

       78
       +
         use ExUnit.Case, async: true

     

       79
       +
       

     

       80
       +
         @subject Foo

     

       81
       +
       

     

       82
       +
         describe "a/3" do

     

       83
       +
           # Some tests here

     

       84
       +
         end

     

       85
       +
       end

     

       86
       +
       ```

     

       87
       +
       

     

       88
       +
       This allows me to see what functionality I am testing.

     

       89
       +
       

     

       90
       +
       Of course that doesn't apply to the Phoenix controllers, as there we do not test

     

       91
       +
       functions, but tuples in form `{method, path}` which I then write as `METHOD

     

       92
       +
       path`, for example `POST /users`.

     

       93
       +
       

     

       94
       +
       ## Avoid module mocking

     

       95
       +
       

     

       96
       +
       In Elixir we have bunch of the mocking libraries out there, but most of them

     

       97
       +
       have quite substantial issue for me - these prevent me from using `async: true`

     

       98
       +
       for my tests. This often causes substantial performance hit, as it prevents

     

       99
       +
       different modules to run in parallel (not single tests, *modules*, but that is

     

       100
       +
       probably material for another post).

     

       101
       +
       

     

       102
       +
       Instead of mocks I prefer to utilise dependency injection. Some people may argue

     

       103
       +
       that "Elixir is FP, not OOP, there is no need for DI" and they cannot be further

     

       104
       +
       from truth. DI isn't related to OOP, it just have different form, called

     

       105
       +
       function arguments. For example, if we want to have function that do something

     

       106
       +
       with time, in particular - current time. Then instead of writing:

     

       107
       +
       

     

       108
       +
       ```elixir

     

       109
       +
       def my_function(a, b) do

     

       110
       +
         do_foo(a, b, DateTime.utc_now())

     

       111
       +
       end

     

       112
       +
       ```

     

       113
       +
       

     

       114
       +
       Which would require me to use mocks for `DateTime` or other workarounds to make

     

       115
       +
       tests time-independent. I would do:

     

       116
       +
       

     

       117
       +
       ```elixir

     

       118
       +
       def my_function(a, b, now \\ DateTime.utc_now()) do

     

       119
       +
         do_foo(a, b, now)

     

       120
       +
       end

     

       121
       +
       ```

     

       122
       +
       

     

       123
       +
       Which still provide me the ergonomics of `my_function/2` as above, but is way

     

       124
       +
       easier to test, as I can pass the date to the function itself. This allows me to

     

       125
       +
       run this test in parallel as it will not cause other tests to do weird stuff

     

       126
       +
       because of altered `DateTime` behaviour.

     

       127
       +
       

     

       128
       +
       ## Avoid `ex_machina` factories

     

       129
       +
       

     

       130
       +
       I have poor experience with tools like `ex_machina` or similar. These often

     

       131
       +
       bring whole [Banana Gorilla Jungle problem][bgj] back, just changed a little, as

     

       132
       +
       now instead of just passing data around, we create all needless structures for

     

       133
       +
       sole purpose of test, even when they aren't needed for anything.

       +
       

     

       187
       +
       For start we can see a single problem there - we do not validate our factories

     

       188
       +
       against our schema changesets. Without additional tests like:

     

       189
       +
       

     

       190
       +
       ```elixir

     

       191
       +
       @subject MyApp.Article

     

       192
       +
       

     

       193
       +
       test "factory conforms to changeset" do

     

       194
       +
         changeset = @subject.changeset(%@subject{}, params_for(:article))

     

       195
       +
       

     

       196
       +
         assert changeset.valid?

     

       197
       +
       end

     

       198
       +
       ```

     

       199
       +
       

     

       200
       +
       We cannot be sure that our tests test what we want them to test. And if we pass

     

       201
       +
       custom attribute values in some tests it gets even worse, because we cannot be

     

       202
       +
       sure if these are conforming either.

     

       203
       +
       

     

       204
       +
       That mean that our tests may be moot, because we aren't testing against real

     

       205
       +
       situations, but against some predefined state.

     

       206
       +
       

     

       207
       +
       Another problem is that if we need to alter the behaviour of the factory it can

     

       208
       +
       became quite convoluted. Imagine situation when we want to test if comments by

     

       209
       +
       author of the post have some special behaviour (for example it has some

     

       210
       +
       additional CSS class to be able to mark them in CSS). That require from us to do

     

       211
       +
       some dancing around passing custom attributes:

     

       212
       +
       

     

       213
       +
       ```elixir

     

       214
       +
       test "comments by author are special" do

     

       215
       +
         post = insert(:post)

     

       216
       +
         comment = insert(:comment, post: post, author: post.author)

     

       217
       +
       

     

       218
       +
         # rest of the test

     

       219
       +
       end

     

       220
       +
       ```

     

       221
       +
       

     

       222
       +
       And this is simplified example. In the past I needed to deal with situations

     

       223
       +
       where I was creating a lot of data to pass through custom attributes to make

     

       224
       +
       test sensible.

     

       225
       +
       

     

       226
       +
       Instead I prefer to do stuff directly in code. Instead of relying on some

     

       227
       +
       "magical" functions provided by some "magical" macros from external library I

     

       228
       +
       can use what I already have - functions in my application.

     

       229
       +
       

     

       230
       +
       Instead of:

     

       231
       +
       

     

       232
       +
       ```elixir

     

       233
       +
       test "comments by author are special" do

     

       234
       +
         post = insert(:post)

     

       235
       +
         comment = insert(:comment, post: post, author: post.author)

     

       236
       +
       

     

       237
       +
         # rest of the test

       242

       243

       247

             email: "john@example.com"

       +
             content: "Foo bar",

     

       252
       +
             title: "Foo bar"

     

       253
       +
           })

     

       254
       +
         comment = MyApp.Blog.create_comment_for(article, %{

     

       255
       +
             author: author,

     

       256
       +
             content: "Foo bar"

     

       257
       +
           })

     

       258
       +
       

     

       259
       +
         # rest of the test

     

       260
       +
       end

     

       261
       +
       ```

     

       262
       +
       

     

       263
       +
       It may be a little bit more verbose, but it makes tests way more readable in my

     

       264
       +
       opinion. You have all details just in place and you know what to expect. And if

     

       265
       +
       you need some piece of data in all (or almost all) tests within

     

       266
       +
       module/`describe` block, then you can always can use `setup/1` blocks. Or you

     

       267
       +
       can create function per module that will generate data for you. As long as your

     

       268
       +
       test module is self-contained and do not receive "magical" data out of thin air,

     

       269
       +
       it is ok for me. But `ex_machina` is, in my opinion, terrible idea brought from

     

       270
       +
       Rails world, that make little to no sense in Elixir.

     

       271
       +
       

     

       272
       +
       If you really need such factories, then just write your own functions that will

     

       273
       +
       use your contexts instead of relying on another library. For example:

     

       274
       +
       

     

       275
       +
       ```elixir

     

       276
       +
       import ExUnit.Assertions

     

       277
       +
       

     

       278
       +
       def create_user(name, email \\ nil, attrs \\ %{}) do

     

       279
       +
         email = email || "#{String.replace(name, " ", ".")}@example.com"

     

       280
       +
         attrs = Map.merge(attrs, %{name: name, email: email})

     

       281
       +
       

     

       282
       +
         assert {:ok, user} = MyApp.Users.create(attrs)

     

       283
       +
       

     

       284
       +
         user

     

       285
       +
       end

     

       286
       +
       

     

       287
       +
       # And so on…

     

       288
       +
       ```

     

       289
       +
       

     

       290
       +
       This way you do not need to check if all tests use correct validations any

     

       291
       +
       longer, as your system will do that for you.

       +
       Largely a port of Radek Kozieł's [Terminal

     

       10
       +
       Theme](https://github.com/panr/hugo-theme-terminal) for Hugo. 4/5ths of my way

     

       11
       +
       through porting this theme, I discovered Paweł Romanowski own independent fork

     

       12
       +
       for Zola, [Terminimal](https://github.com/pawroman/zola-theme-terminimal),

     

       13
       +
       which helped me get the PostCSS to Sass styling conversion done more

     

       14
       +
       quickly. My sincerest thanks to both of you!

       ## differences

     

       17
       +
       

     

       18
       +
       This theme is largely true to the original by Radek, but there are some mild

     

       19
       +
       differences. They are almost all stylistic in nature and are intended to

     

       20
       +
       emphasize minimalism even more. Some of them are as follows:

     

       21
       +
       - tags are now included in a post's meta data.

     

       22
       +
       - no post image previews.

     

       23
       +
       - categories are included in the taxonomy.

     

       24
       +
       - bullet points have slightly more margin and different symbols for nesting.

     

       25
       +
       - no social media or comment support.

     

       26
       +
       

     

       27
       +
       Some of these might be added later and [PR's are always

     

       28
       +
       welcomed](https://github.com/ejmg/zerm/pulls).

       ## configuration

     

       31
       +
       

     

       32
       +
       Please follow the Zola documentation for [how to use a

     

       33
       +
       theme](https://www.getzola.org/documentation/themes/installing-and-using-themes/#installing-a-theme).

     

       34
       +
       

     

       35
       +
       In `config.toml`, you will find all values for customization that are supported

     

       36
       +
       thus far have documentation explaining how they are used. If there is any confusion or something is not working as intended, [please open an issue](https://github.com/ejmg/zerm/issues)!

     

       37

       38
       +
       ## math

     

       39
       +
       You can use KaTeX for mathematical typesetting.

     

       40
       +
       Assets are only available if you opt-in on a per-page level through

     

       41
       +
       a single line (`math=true`) on the extra section of the page frontmatter.

       56

       Pages wich doesn't opt-in are not affected in any way, so you doesn't have

     

       57

       to worry about any performance hit.

       If the text between `$$` contains newlines it will rendered in display mode:

       This is zerm, a minimalist theme for Zola based[^1] off of [panr's](https://twitter.com/panr)

     

       18
       +
       theme for Hugo.

     

       19
       +
       

     

       20
       +
       While it's largely faithful to the original, there are some changes:

     

       21
       +
       - no prism.js integration, instead we use Zola's syntax highlighting to reduce overhead.

     

       22
       +
       - removal of PostCSS and leveraging Zola's use of Sass for simple styling.

     

       23
       +
         - much thanks to [Paweł

     

       24
       +
           Romanowski's](https://github.com/pawroman/zola-theme-terminimal/)

     

       25
       +
           independent fork of Terminal. Their Sass stylings saved me the overhead of

     

       26
       +
           figuring it out myself.

     

       27
       +
       - no preview images. I want a theme that is focused on content.

     

       28
       +
       - support for anchor links.

     

       29
       +
       - Other small, opinionated changes that I think lend to the minimalism and

     

       30
       +
         aesthetic of zerm.

     

       31

       32
       +
         

     

       33
       +
       Things this theme does not have but either Terminal or Terminimal might:

     

       34
       +
       - better short-codes for things like embedding videos or images, though I will

     

       35
       +
         work on this over time.

     

       36
       +
       - better support for things like comments and social media. As of now, I have

     

       37
       +
         no plans to add this but [PR's are always
