│ │ │ │ │  </h2>
│ │ │ │ │  <p>BIFs are functions that for some reason are built-in to the Erlang virtual
│ │ │ │ │  machine. BIFs often implement functionality that is impossible or is too
│ │ │ │ │  inefficient to implement in Erlang. Some BIFs can be called using the function
│ │ │ │ │  name only but they are by default belonging to the <code class="inline">erlang</code> module. For example,
│ │ │ │ │  the call to the BIF <code class="inline">trunc</code> below is equivalent to a call to <code class="inline">erlang:trunc</code>.</p><p>As shown, first it is checked if a year is leap. If a year is divisible by 400,
│ │ │ │ │  it is a leap year. To determine this, first divide the year by 400 and use the
│ │ │ │ │  BIF <code class="inline">trunc</code> (more about this later) to cut off any decimals. Then multiply by
│ │ │ │ │  400 again and see if the same value is returned again. For example, year 2004:</p><pre><code class="makeup erlang" translate="no"><span class="mi">2004</span><span class="w"> </span><span class="o">/</span><span class="w"> </span><span class="mi">400</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="mf">5.01</span><span class="w">

│ │ │ │ │  <p>Before improving the messenger program, let us look at some general principles,
│ │ │ │ │  using the ping pong program as an example. Recall that when &quot;ping&quot; finishes, it
│ │ │ │ │  tells &quot;pong&quot; that it has done so by sending the atom <code class="inline">finished</code> as a message to
│ │ │ │ │  &quot;pong&quot; so that &quot;pong&quot; can also finish. Another way to let &quot;pong&quot; finish is to
│ │ │ │ │  make &quot;pong&quot; exit if it does not receive a message from ping within a certain
│ │ │ │ │  time. This can be done by adding a <em>time-out</em> to <code class="inline">pong</code> as shown in the
│ │ │ │ │ -following example:</p><pre><code class="makeup erlang" translate="no"><span class="p">-</span><span class="na">module</span><span class="p" data-group-id="4936811104-1">(</span><span class="ss">tut19</span><span class="p" data-group-id="4936811104-1">)</span><span class="p">.</span><span class="w">

│ │ │ │ │  <p>The main advantage of using records rather than tuples is that fields in a

│ │ │ │ │  arguments (<code class="inline">server_transfer/4</code>) and one with five (<code class="inline">server_transfer/5</code>). These
│ │ │ │ │  are regarded by Erlang as two separate functions.</p><p>Notice how to write the <code class="inline">server</code> function so that it calls itself, through
│ │ │ │ │  <code class="inline">server(User_List)</code>, and thus creates a loop. The Erlang compiler is &quot;clever&quot;
│ │ │ │ │  and optimizes the code so that this really is a sort of loop and not a proper
│ │ │ │ │  function call. But this only works if there is no code after the call.
│ │ │ │ │  Otherwise, the compiler expects the call to return and make a proper function
│ │ │ │ │  call. This would result in the process getting bigger and bigger for every loop.</p><p>Functions in the <code class="inline">lists</code> module are used. This is a very useful module and a
│ │ │ │ │  study of the manual page is recommended (<code class="inline">erl -man lists</code>).
│ │ │ │ │  <code class="inline">lists:keymember(Key,Position,Lists)</code> looks through a list of tuples and looks
│ │ │ │ │  at <code class="inline">Position</code> in each tuple to see if it is the same as <code class="inline">Key</code>. The first element
│ │ │ │ │  is position 1. If it finds a tuple where the element at <code class="inline">Position</code> is the same
│ │ │ │ │ -as <code class="inline">Key</code>, it returns <code class="inline">true</code>, otherwise <code class="inline">false</code>.</p><pre><code class="makeup erlang" translate="no"><span class="gp unselectable">3&gt; </span><span class="nc">lists</span><span class="p">:</span><span class="nf">keymember</span><span class="p" data-group-id="2101908324-1">(</span><span class="ss">a</span><span class="p">,</span><span class="w"> </span><span class="mi">2</span><span class="p">,</span><span class="w"> </span><span class="p" data-group-id="2101908324-2">[</span><span class="p" data-group-id="2101908324-3">{</span><span class="ss">x</span><span class="p">,</span><span class="ss">y</span><span class="p">,</span><span class="ss">z</span><span class="p" data-group-id="2101908324-3">}</span><span class="p">,</span><span class="p" data-group-id="2101908324-4">{</span><span class="ss">b</span><span class="p">,</span><span class="ss">b</span><span class="p">,</span><span class="ss">b</span><span class="p" data-group-id="2101908324-4">}</span><span class="p">,</span><span class="p" data-group-id="2101908324-5">{</span><span class="ss">b</span><span class="p">,</span><span class="ss">a</span><span class="p">,</span><span class="ss">c</span><span class="p" data-group-id="2101908324-5">}</span><span class="p">,</span><span class="p" data-group-id="2101908324-6">{</span><span class="ss">q</span><span class="p">,</span><span class="ss">r</span><span class="p">,</span><span class="ss">s</span><span class="p" data-group-id="2101908324-6">}</span><span class="p" data-group-id="2101908324-2">]</span><span class="p" data-group-id="2101908324-1">)</span><span class="p">.</span><span class="w">

│ │ │ │ │  <a href="binaryhandling.xhtml#match_context">match context</a> is created. The match context
│ │ │ │ │  points to the first byte of the binary. 1 byte is matched out and the match
│ │ │ │ │  context is updated to point to the second byte in the binary.</p><p>At this point it would make sense to create a
│ │ │ │ │  <a href="binaryhandling.xhtml#sub_binary">sub binary</a>, but in this particular example the
│ │ │ │ │  compiler sees that there will soon be a call to a function (in this case, to

│ │ │ │ │  with a sub binary. The instruction that initializes the matching operation
│ │ │ │ │  basically does nothing when it sees that it was passed a match context instead
│ │ │ │ │  of a binary.</p><p>When the end of the binary is reached and the second clause matches, the match

│ │ │ │ │  no sub binaries.</p><p>Notice that the match context in <code class="inline">my_binary_to_list/1</code> was discarded when the

│ │ │ │  arguments (<code class="inline">server_transfer/4</code>) and one with five (<code class="inline">server_transfer/5</code>). These
│ │ │ │  are regarded by Erlang as two separate functions.</p><p>Notice how to write the <code class="inline">server</code> function so that it calls itself, through
│ │ │ │  <code class="inline">server(User_List)</code>, and thus creates a loop. The Erlang compiler is &quot;clever&quot;
│ │ │ │  and optimizes the code so that this really is a sort of loop and not a proper
│ │ │ │  function call. But this only works if there is no code after the call.
│ │ │ │  Otherwise, the compiler expects the call to return and make a proper function
│ │ │ │  call. This would result in the process getting bigger and bigger for every loop.</p><p>Functions in the <code class="inline">lists</code> module are used. This is a very useful module and a
│ │ │ │  study of the manual page is recommended (<code class="inline">erl -man lists</code>).
│ │ │ │  <code class="inline">lists:keymember(Key,Position,Lists)</code> looks through a list of tuples and looks
│ │ │ │  at <code class="inline">Position</code> in each tuple to see if it is the same as <code class="inline">Key</code>. The first element
│ │ │ │  is position 1. If it finds a tuple where the element at <code class="inline">Position</code> is the same
│ │ │ │ -as <code class="inline">Key</code>, it returns <code class="inline">true</code>, otherwise <code class="inline">false</code>.</p><pre><code class="makeup erlang" translate="no"><span class="gp unselectable">3&gt; </span><span class="nc">lists</span><span class="p">:</span><span class="nf">keymember</span><span class="p" data-group-id="4280017403-1">(</span><span class="ss">a</span><span class="p">,</span><span class="w"> </span><span class="mi">2</span><span class="p">,</span><span class="w"> </span><span class="p" data-group-id="4280017403-2">[</span><span class="p" data-group-id="4280017403-3">{</span><span class="ss">x</span><span class="p">,</span><span class="ss">y</span><span class="p">,</span><span class="ss">z</span><span class="p" data-group-id="4280017403-3">}</span><span class="p">,</span><span class="p" data-group-id="4280017403-4">{</span><span class="ss">b</span><span class="p">,</span><span class="ss">b</span><span class="p">,</span><span class="ss">b</span><span class="p" data-group-id="4280017403-4">}</span><span class="p">,</span><span class="p" data-group-id="4280017403-5">{</span><span class="ss">b</span><span class="p">,</span><span class="ss">a</span><span class="p">,</span><span class="ss">c</span><span class="p" data-group-id="4280017403-5">}</span><span class="p">,</span><span class="p" data-group-id="4280017403-6">{</span><span class="ss">q</span><span class="p">,</span><span class="ss">r</span><span class="p">,</span><span class="ss">s</span><span class="p" data-group-id="4280017403-6">}</span><span class="p" data-group-id="4280017403-2">]</span><span class="p" data-group-id="4280017403-1">)</span><span class="p">.</span><span class="w">

│ │ │ │  <p>The main advantage of using records rather than tuples is that fields in a
│ │ │ │  record are accessed by name, whereas fields in a tuple are accessed by position.
│ │ │ │  To illustrate these differences, suppose that you want to represent a person
│ │ │ │  with the tuple <code class="inline">{Name, Address, Phone}</code>.</p><p>To write functions that manipulate this data, remember the following:</p><ul><li>The <code class="inline">Name</code> field is the first element of the tuple.</li><li>The <code class="inline">Address</code> field is the second element.</li><li>The <code class="inline">Phone</code> field is the third element.</li></ul><p>For example, to extract data from a variable <code class="inline">P</code> that contains such a tuple, you
│ │ │ │  can write the following code and then use pattern matching to extract the
│ │ │ │ -relevant fields:</p><pre><code class="makeup erlang" translate="no"><span class="n">Name</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="nf">element</span><span class="p" data-group-id="9252611895-1">(</span><span class="mi">1</span><span class="p">,</span><span class="w"> </span><span class="n">P</span><span class="p" data-group-id="9252611895-1">)</span><span class="p">,</span><span class="w">

│ │ │ │  suitable text editor. The file name <code class="inline">tut.erl</code> is important, and also that it is
│ │ │ │  in the same directory as the one where you started <code class="inline">erl</code>). If you are lucky your
│ │ │ │  editor has an Erlang mode that makes it easier for you to enter and format your
│ │ │ │  code nicely (see <a href="../../lib/tools-4.1.1/doc/html/erlang_mode_chapter.html">The Erlang mode for Emacs</a>

│ │ │ │  </h2>
│ │ │ │  <p>BIFs are functions that for some reason are built-in to the Erlang virtual
│ │ │ │  machine. BIFs often implement functionality that is impossible or is too
│ │ │ │  inefficient to implement in Erlang. Some BIFs can be called using the function
│ │ │ │  name only but they are by default belonging to the <code class="inline">erlang</code> module. For example,
│ │ │ │  the call to the BIF <code class="inline">trunc</code> below is equivalent to a call to <code class="inline">erlang:trunc</code>.</p><p>As shown, first it is checked if a year is leap. If a year is divisible by 400,
│ │ │ │  it is a leap year. To determine this, first divide the year by 400 and use the
│ │ │ │  BIF <code class="inline">trunc</code> (more about this later) to cut off any decimals. Then multiply by
│ │ │ │  400 again and see if the same value is returned again. For example, year 2004:</p><pre><code class="makeup erlang" translate="no"><span class="mi">2004</span><span class="w"> </span><span class="o">/</span><span class="w"> </span><span class="mi">400</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="mf">5.01</span><span class="w">

│ │ │ │  </h2>
│ │ │ │  <p>In addition to the collection algorithm described above, the Erlang garbage collector also provides generational garbage collection. An additional heap, called the old heap, is used where the long lived data is stored. The original heap is called the young heap, or sometimes the allocation heap.</p><p>With this in mind we can look at the Erlang's garbage collection again. During the copy stage anything that should be copied to the young <em>to space</em> is instead copied to the old <em>to space</em> <em>if</em> it is <a href="https://github.com/erlang/otp/blob/OTP-18.0/erts/emulator/beam/erl_gc.c#L1127">below the <em>high-watermark</em></a>.</p><p><img src="assets/gc-watermark.png" alt="Garbage collection: heap scan"/></p><p>The <a href="https://github.com/erlang/otp/blob/OTP-18.0/erts/emulator/beam/erl_process.h#L1021"><em>high-watermark</em></a> is placed where the previous garbage collection (described in <a href="#overview">Overview</a>) ended and we have introduced a new area called the old heap. When doing the normal garbage collection pass, any term that is located below the high-watermark is copied to the old <em>to space</em> instead of the young.</p><p><img src="assets/gc-watermark-2.png" alt="Garbage collection: heap scan"/></p><p>In the next garbage collection, any pointers to the old heap will be ignored and not scanned. This way the garbage collector does not have to scan the long-lived terms.</p><p>Generational garbage collection aims to increase performance at the expense of memory. This is achieved because only the young, smaller, heap is considered in most garbage collections.</p><p>The generational hypothesis predicts that most terms tend to die young (see D. Ungar in <a href="#references">References</a>), and for an immutable language such as Erlang, young terms die even faster than in other languages. So for most usage patterns the data in the new heap will die very soon after it is allocated. This is good because it limits the amount of data copied to the old heap and also because the garbage collection algorithm used is proportional to the amount of live data on the heap.</p><p>One critical issue to note here is that any term on the young heap can reference terms on the old heap but <em>no</em> term on the old heap may refer to a term on the young heap. This is due to the nature of the copy algorithm. Anything referenced by an old heap term is not included in the reference tree, root-set and its followers, and hence is not copied. If it was, the data would be lost, fire and brimstone would rise to cover the earth. Fortunately, this comes naturally for Erlang because the terms are immutable and thus there can be no pointers modified on the old heap to point to the young heap.</p><p>To reclaim data from the old heap, both young and old heaps are included during the collection and copied to a common <em>to space</em>. Both the <em>from space</em> of the young and old heap are then deallocated and the procedure will start over from the beginning. This type of garbage collection is called a full sweep and is triggered when the size of the area under the high-watermark is larger than the size of the free area of the old heap. It can also be triggered by doing a manual call to <a href="http://erlang.org/doc/man/erlang.html#garbage_collect-0">erlang:garbage_collect()</a>, or by running into the young garbage collection limit set by [spawn_opt(fun(),<a href="http://erlang.org/doc/man/erlang.html#spawn_opt-4">{fullsweep_after, N}])</a> where N is the number of young garbage collections to do before forcing a garbage collection of both young and old heap.</p><h2 id="the-young-heap" class="section-heading">

Then all that has to be done to determine if something is a literal or not is <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_alloc.h#L322-L324">two quick pointer checks</a>. This system relies on the fact that a memory page that has not been touched yet does not take any actual space. So even if 1 GB of virtual memory is mapped, only the memory which is actually needed for literals is allocated in ram. The size of the literal area is configurable through the +MIscs erts_alloc option.</p><p>On 32 bit systems, there is not enough virtual memory space to allocate 1 GB for just literals, so instead small 256 KB sized literal regions are created on demand and a card mark bit-array of the entire 32 bit memory space is then used to determine if a term is a literal or not. Since the total memory space is only 32 bits, the card mark bit-array is only 256 words large. On a 64 bit system the same bit-array would have to be 1 tera words large, so this technique is only viable on 32 bit systems. Doing <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_alloc.h#L316-L319">lookups in the array</a> is a little more expensive then just doing the pointer checks that can be done in 64 bit systems, but not extremely so.</p><p>On 64 bit windows, on which erts_alloc cannot do unreserved virtual memory mappings, a <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_term.h#L59">special tag</a> within the Erlang term object is used to determine if something <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_term.h#L248-L252">is a literal or not</a>. This is very cheap, however, the tag is only available on 64 bit machines, and it is possible to do a great deal of other nice optimizations with this tag in the future (like for instance a more compact list implementation) so it is not used on operating systems where it is not needed.</p><p>This behaviour is different from how it worked prior to Erlang/OTP 19.0. Before 19.0 the literal check was done by checking if the pointer pointed to the young or old heap block. If it did not, then it was considered a literal. This lead to considerable overhead and strange memory usage scenarios, so it was removed in 19.0.</p><h2 id="binary-heap" class="section-heading">

Then all that has to be done to determine if something is a literal or not is <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_alloc.h#L322-L324">two quick pointer checks</a>. This system relies on the fact that a memory page that has not been touched yet does not take any actual space. So even if 1 GB of virtual memory is mapped, only the memory which is actually needed for literals is allocated in ram. The size of the literal area is configurable through the +MIscs erts_alloc option.</p><p>On 32 bit systems, there is not enough virtual memory space to allocate 1 GB for just literals, so instead small 256 KB sized literal regions are created on demand and a card mark bit-array of the entire 32 bit memory space is then used to determine if a term is a literal or not. Since the total memory space is only 32 bits, the card mark bit-array is only 256 words large. On a 64 bit system the same bit-array would have to be 1 tera words large, so this technique is only viable on 32 bit systems. Doing <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_alloc.h#L316-L319">lookups in the array</a> is a little more expensive then just doing the pointer checks that can be done in 64 bit systems, but not extremely so.</p><p>On 64 bit windows, on which erts_alloc cannot do unreserved virtual memory mappings, a <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_term.h#L59">special tag</a> within the Erlang term object is used to determine if something <a href="https://github.com/erlang/otp/blob/OTP-19.0/erts/emulator/beam/erl_term.h#L248-L252">is a literal or not</a>. This is very cheap, however, the tag is only available on 64 bit machines, and it is possible to do a great deal of other nice optimizations with this tag in the future (like for instance a more compact list implementation) so it is not used on operating systems where it is not needed.</p><p>This behaviour is different from how it worked prior to Erlang/OTP 19.0. Before 19.0 the literal check was done by checking if the pointer pointed to the young or old heap block. If it did not, then it was considered a literal. This lead to considerable overhead and strange memory usage scenarios, so it was removed in 19.0.</p><h2 id="binary-heap" class="section-heading">

│ │ │ │  </h2>
│ │ │ │  <p>The binary heap works as a large object space for binary terms that are greater than 64 bytes (from now on called off-heap binaries). The binary heap is <a href="https://en.wikipedia.org/wiki/Reference_counting">reference counted</a> and a pointer to the off-heap binary is stored on the process heap. To keep track of when to decrement the reference counter of the off-heap binary, a linked list (the MSO - mark and sweep object list) containing funs and externals as well as off-heap binaries is woven through the heap. After a garbage collection is done, the <a href="https://github.com/erlang/otp/blob/OTP-18.0/erts/emulator/beam/erl_gc.c#L2299">MSO list is swept</a> and any off-heap binary that does not have a <a href="https://github.com/erlang/otp/blob/OTP-18.0/erts/emulator/beam/erl_gc.c#L2325">move marker</a> written into the header words has its reference <a href="https://github.com/erlang/otp/blob/OTP-18.0/erts/emulator/beam/erl_gc.c#L2344-L2367">decremented and is potentially freed</a>.</p><p>All items in the MSO list are ordered by the time they were added to the process heap, so when doing a minor garbage collection, the MSO sweeper only has to sweep until it <a href="https://github.com/erlang/otp/blob/OTP-18.0/erts/emulator/beam/erl_gc.c#L2369">encounters an off-heap binary that is on the old heap</a>.</p><h3 id="virtual-binary-heap" class="section-heading">

│ │ │ │  wants Erlang to read all information necessary from start and use that for
│ │ │ │  resolving names and addresses. If lookup fails, Erlang is to request the data
│ │ │ │  from a nameserver (using the Erlang DNS client, set to use EDNS allowing larger
│ │ │ │  responses). The resolver configuration is updated when its configuration file
│ │ │ │  changes. Also, DNS records are never to be cached. The user configuration file

│ │ │ │ │  <p>If you need to perform configuration operations to run your test, you can

│ │ │ │ │  function is configuration data, or <code class="inline">Config</code>. This is a list of key-value tuples
│ │ │ │ │  that get passed from the configuration function to the test cases (possibly
│ │ │ │ │  through configuration functions on &quot;lower level&quot;). The data flow looks as

│ │ │ │ │  <a href="#edit_config/3"><code class="inline">edit_config/3-5</code></a> to send an edit-config RPC), with the
│ │ │ │ │  server reply as return value. There are functions for each RPC defined in RFC

│ │ │ │ │  <a href="#send_rpc/2"><code class="inline">send_rpc/2,3</code></a>, that can be used to send an arbitrary RPC not

│ │ │ │  <p>If you need to perform configuration operations to run your test, you can
│ │ │ │  implement configuration functions in your suite. The result from a configuration
│ │ │ │  function is configuration data, or <code class="inline">Config</code>. This is a list of key-value tuples
│ │ │ │  that get passed from the configuration function to the test cases (possibly
│ │ │ │  through configuration functions on &quot;lower level&quot;). The data flow looks as

│ │ │ │  <p>The <code class="inline">Company</code> database, introduced in
│ │ │ │  <a href="mnesia_chap2.html#getting_started">Getting Started</a>, has three tables that store
│ │ │ │  records (<code class="inline">employee</code>, <code class="inline">dept</code>, <code class="inline">project</code>), and three tables that store
│ │ │ │  relationships (<code class="inline">manager</code>, <code class="inline">at_dep</code>, <code class="inline">in_proj</code>). This is a normalized data model,
│ │ │ │  which has some advantages over a non-normalized data model.</p><p>It is more efficient to do a generalized search in a normalized database. Some
│ │ │ │  operations are also easier to perform on a normalized data model. For example,
│ │ │ │ -one project can easily be removed, as the following example illustrates:</p><pre><code class="makeup erlang" translate="no"><span class="nf">remove_proj</span><span class="p" data-group-id="0601111925-1">(</span><span class="n">ProjName</span><span class="p" data-group-id="0601111925-1">)</span><span class="w"> </span><span class="p">-&gt;</span><span class="w">

│ │ │ │  a normalized database model would be a data model that is not even in first
│ │ │ │  normal form. <code class="inline">Mnesia</code> is suitable for applications such as telecommunications,
│ │ │ │  because it is easy to organize data in a flexible manner. A <code class="inline">Mnesia</code> database is
│ │ │ │  always organized as a set of tables. Each table is filled with rows, objects,
│ │ │ │  and records. What sets <code class="inline">Mnesia</code> apart is that individual fields in a record can
│ │ │ │  contain any type of compound data structures. An individual field in a record
│ │ │ │  can contain lists, tuples, functions, and even record code.</p><p>Many telecommunications applications have unique requirements on lookup times
│ │ │ │  for certain types of records. If the <code class="inline">Company</code> database had been a part of a
│ │ │ │  telecommunications system, it could be to minimize the lookup time of an
│ │ │ │  employee <em>together</em> with a list of the projects the employee is working on. If
│ │ │ │  this is the case, a drastically different data model without direct
│ │ │ │  relationships can be chosen. You would then have only the records themselves,
│ │ │ │  and different records could contain either direct references to other records,
│ │ │ │ -or contain other records that are not part of the <code class="inline">Mnesia</code> schema.</p><p>The following record definitions can be created:</p><pre><code class="makeup erlang" translate="no"><span class="p">-</span><span class="na">record</span><span class="p" data-group-id="6038007169-1">(</span><span class="ss">employee</span><span class="p">,</span><span class="w"> </span><span class="p" data-group-id="6038007169-2">{</span><span class="ss">emp_no</span><span class="p">,</span><span class="w">

│ │ │ │ │  following:</p><ul><li>Initiation of the system tracer. This is automatically done when a trace port
│ │ │ │ │  is started with <a href="ttb.xhtml#tracer/0"><code class="inline">ttb:tracer/0,1,2</code></a>.</li><li>Creation of match specifications that activates sequential tracing.</li></ul><p>Starting sequential tracing requires that a tracer is started with function
│ │ │ │ │  <code class="inline">ttb:tracer/0,1,2</code>. Sequential tracing can then be started in either of the
│ │ │ │ │  following ways:</p><ul><li>Through a trigger function with a match specification created with

│ │ │ │  <p>The <code class="inline">dbg</code> module is primarily targeted towards tracing through the
│ │ │ │  <a href="../../../../lib/kernel-10.2.7.1/doc/html/trace.html#process/4"><code class="inline">trace:process/4</code></a> function. It is sometimes desired to trace messages in a more

│ │ │ │  sometimes called &quot;forlopp tracing&quot;). <code class="inline">dbg</code> can interpret messages generated from
│ │ │ │  <code class="inline">seq_trace</code> and the same tracer function for both types of tracing can be used.
│ │ │ │  The <code class="inline">seq_trace</code> messages can also be sent to a trace port for further analysis.</p><p>As a match specification can turn on sequential tracing, the combination of
│ │ │ │  <code class="inline">dbg</code> and <code class="inline">seq_trace</code> can be powerful. This brief example shows a session

│ │ │ │ │  <p>The <code class="inline">dbg</code> module is primarily targeted towards tracing through the
│ │ │ │ │  <a href="../../../../lib/kernel/doc/html/trace.html#process/4"><code class="inline">trace:process/4</code></a> function. It is sometimes desired to trace messages in a more
│ │ │ │ │  delicate way, which can be done with the help of the <a href="../../../../lib/kernel/doc/html/seq_trace.html"><code class="inline">seq_trace</code></a> module.</p><p><a href="../../../../lib/kernel/doc/html/seq_trace.html"><code class="inline">seq_trace</code></a> implements sequential tracing (known in the AXE10 world, and
│ │ │ │ │  sometimes called &quot;forlopp tracing&quot;). <code class="inline">dbg</code> can interpret messages generated from
│ │ │ │ │  <code class="inline">seq_trace</code> and the same tracer function for both types of tracing can be used.
│ │ │ │ │  The <code class="inline">seq_trace</code> messages can also be sent to a trace port for further analysis.</p><p>As a match specification can turn on sequential tracing, the combination of
│ │ │ │ │  <code class="inline">dbg</code> and <code class="inline">seq_trace</code> can be powerful. This brief example shows a session
│ │ │ │ │ -where sequential tracing is used to trace the <code class="inline">dbg</code> module and the trace itself:</p><pre><code class="makeup erlang" translate="no"><samp class="gp unselectable">1&gt; </samp><samp class="nc">dbg</samp><samp class="p">:</samp><samp class="nf">tracer</samp><samp class="p" data-group-id="0393772577-1">(</samp><samp class="p" data-group-id="0393772577-1">)</samp><samp class="p">.</samp><samp class="w">

│ │ │ │ │  <a href="uri_string.xhtml#t:uri_map/0"><code class="inline">uri_map()</code></a>. The parsing only splits the URI into

│ │ │ │ │  You can try to normalize the input with <a href="uri_string.xhtml#normalize/1"><code class="inline">uri_string:normalize/1</code></a>. The normalize

│ │ │ │ │  containing printable characters in bytewise or UTF-8 encoding. But what is a
│ │ │ │ │  printable character? One view is that anything the Unicode standard thinks is
│ │ │ │ │  printable, is also printable according to the heuristic detection. The result is
│ │ │ │ │  then that almost any list of integers are deemed a string, and all sorts of
│ │ │ │ │  characters are printed, maybe also characters that your terminal lacks in its
│ │ │ │ │  font set (resulting in some unappreciated generic output). Another way is to
│ │ │ │ │  keep it backward compatible so that only the ISO Latin-1 character set is used
│ │ │ │ │  to detect a string. A third way is to let the user decide exactly what Unicode
│ │ │ │ │  ranges that are to be viewed as characters.</p><p>As from Erlang/OTP R16B you can select the ISO Latin-1 range or the whole
│ │ │ │ │  Unicode range by supplying startup flag <code class="inline">+pc latin1</code> or <code class="inline">+pc unicode</code>,
│ │ │ │ │  respectively. For backward compatibility, <code class="inline">latin1</code> is default. This only
│ │ │ │ │  controls how heuristic string detection is done. More ranges are expected to be

│ │ │ │  containing printable characters in bytewise or UTF-8 encoding. But what is a
│ │ │ │  printable character? One view is that anything the Unicode standard thinks is
│ │ │ │  printable, is also printable according to the heuristic detection. The result is
│ │ │ │  then that almost any list of integers are deemed a string, and all sorts of
│ │ │ │  characters are printed, maybe also characters that your terminal lacks in its
│ │ │ │  font set (resulting in some unappreciated generic output). Another way is to
│ │ │ │  keep it backward compatible so that only the ISO Latin-1 character set is used
│ │ │ │  to detect a string. A third way is to let the user decide exactly what Unicode
│ │ │ │  ranges that are to be viewed as characters.</p><p>As from Erlang/OTP R16B you can select the ISO Latin-1 range or the whole
│ │ │ │  Unicode range by supplying startup flag <code class="inline">+pc latin1</code> or <code class="inline">+pc unicode</code>,
│ │ │ │  respectively. For backward compatibility, <code class="inline">latin1</code> is default. This only
│ │ │ │  controls how heuristic string detection is done. More ranges are expected to be
│ │ │ │  added in the future, enabling tailoring of the heuristics to the language and

│ │ │ │  </h3>
│ │ │ │  <p>A common method of identifying encoding in text files is to put a Byte Order
│ │ │ │  Mark (BOM) first in the file. The BOM is the code point 16#FEFF encoded in the
│ │ │ │  same way as the remaining file. If such a file is to be read, the first few
│ │ │ │  bytes (depending on encoding) are not part of the text. This code outlines how
│ │ │ │  to open a file that is believed to have a BOM, and sets the files encoding and
│ │ │ │ -position for further sequential reading (preferably using the <a href="io.html"><code class="inline">io</code></a> module).</p><p>Notice that error handling is omitted from the code:</p><pre><code class="makeup erlang" translate="no"><span class="nf">open_bom_file_for_reading</span><span class="p" data-group-id="8135456877-1">(</span><span class="n">File</span><span class="p" data-group-id="8135456877-1">)</span><span class="w"> </span><span class="p">-&gt;</span><span class="w">

│ │ │ │  <a href="uri_string.html#t:uri_map/0"><code class="inline">uri_map()</code></a>. The parsing only splits the URI into

│ │ │ │        scheme =&gt; &quot;http&quot;}}</code></pre><p>The input is a valid URI but how can you decode those percent-encoded octets?
│ │ │ │  You can try to normalize the input with <a href="uri_string.html#normalize/1"><code class="inline">uri_string:normalize/1</code></a>. The normalize
│ │ │ │  operation decodes those percent-encoded triplets that correspond to a character

│ │ │ │  <p>Merl can only parse a fragment of text if it follows the basic syntactical rules
│ │ │ │  of Erlang. In most places, a normal Erlang variable can be used as metavariable,
│ │ │ │ -for example:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="6559523988-1">(</span><span class="s">&quot;f(_@Arg)&quot;</span><span class="p" data-group-id="6559523988-1">)</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="n">Expr</span></code></pre><p>but if you want to match on something like the name of a function, you have to

For example, the

Note
│ │ │ │  the use of the anonymous variable <code class="inline">9090</code> to ignore the line number. To match and
│ │ │ │  also bind a metavariable that must be an integer literal, we can use the
│ │ │ │  convention of ending the integer with a 9, turning it into a Q-prefixed variable
│ │ │ │  on the Erlang level (see the previous section).</p><h4>Globs</h4><p>Whenever you want to match out a number of elements in a sequence (zero or more)

However, you cannot have two globs as part

│ │ │ │ -metavariable directly where you would like it. For example, you cannot write:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="4389303986-1">(</span><span class="s">&quot;-export([_@@Name]).&quot;</span><span class="p" data-group-id="4389303986-1">)</span></code></pre><p>to match out all name/arity pairs in the export list, or to insert a list of
│ │ │ │ +metavariable directly where you would like it. For example, you cannot write:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="5918321621-1">(</span><span class="s">&quot;-export([_@@Name]).&quot;</span><span class="p" data-group-id="5918321621-1">)</span></code></pre><p>to match out all name/arity pairs in the export list, or to insert a list of
│ │ │ │  exports in a declaration, because the Erlang parser only allows elements on the
│ │ │ │  form <code class="inline">A/I</code> (where <code class="inline">A</code> is an atom and <code class="inline">I</code> an integer) in the export list. A
│ │ │ │  variable like the above is not allowed, but neither is a single atom or integer,
│ │ │ │  so <code class="inline">'@@Name'</code> or <code class="inline">909919</code> would not work either.</p><p>What you have to do in such cases is to write your metavariable in a
│ │ │ │  syntactically valid position, and use lifting markers to denote where it should
│ │ │ │ -really apply, as in:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="4958105336-1">(</span><span class="s">&quot;-export([&#39;@_@Name&#39;/0]).&quot;</span><span class="p" data-group-id="4958105336-1">)</span></code></pre><p>This causes the variable to be lifted (after parsing) to the next higher level
│ │ │ │ +really apply, as in:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="2235767859-1">(</span><span class="s">&quot;-export([&#39;@_@Name&#39;/0]).&quot;</span><span class="p" data-group-id="2235767859-1">)</span></code></pre><p>This causes the variable to be lifted (after parsing) to the next higher level
│ │ │ │  in the syntax tree, replacing that entire subtree. In this case, the
│ │ │ │  <code class="inline">'@_@Name'/0</code> will be replaced with <code class="inline">'@@Name'</code>, and the <code class="inline">/0</code> part was just used
│ │ │ │  as dummy notation and will be discarded.</p><p>You may even need to apply lifting more than once. To match the entire export
│ │ │ │ -list as a single syntax tree, you can write:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="2891830631-1">(</span><span class="s">&quot;-export([&#39;@__Name&#39;/0]).&quot;</span><span class="p" data-group-id="2891830631-1">)</span></code></pre><p>using two underscores, but with no glob marker this time. This will make the
│ │ │ │ +list as a single syntax tree, you can write:</p><pre><code class="makeup erlang" translate="no"><span class="o">?</span><span class="n">Q</span><span class="p" data-group-id="2062161309-1">(</span><span class="s">&quot;-export([&#39;@__Name&#39;/0]).&quot;</span><span class="p" data-group-id="2062161309-1">)</span></code></pre><p>using two underscores, but with no glob marker this time. This will make the
│ │ │ │  entire <code class="inline">['@__Name'/0]</code> part be replaced with <code class="inline">'@Name'</code>.</p><p>Sometimes, the tree structure of a code fragment is not very obvious, and parts
│ │ │ │  of the structure may be invisible when printed as source code. For instance, a
│ │ │ │ -simple function definition like the following:</p><pre><code class="makeup erlang" translate="no"><span class="nf">zero</span><span class="p" data-group-id="1127042731-1">(</span><span class="p" data-group-id="1127042731-1">)</span><span class="w"> </span><span class="p">-&gt;</span><span class="w"> </span><span class="mi">0</span><span class="p">.</span></code></pre><p>consists of the name (the atom <code class="inline">zero</code>), and a list of clauses containing the
│ │ │ │ +simple function definition like the following:</p><pre><code class="makeup erlang" translate="no"><span class="nf">zero</span><span class="p" data-group-id="2777369754-1">(</span><span class="p" data-group-id="2777369754-1">)</span><span class="w"> </span><span class="p">-&gt;</span><span class="w"> </span><span class="mi">0</span><span class="p">.</span></code></pre><p>consists of the name (the atom <code class="inline">zero</code>), and a list of clauses containing the
│ │ │ │  single clause <code class="inline">() -&gt; 0</code>. The clause consists of an argument list (empty), a
│ │ │ │  guard (empty), and a body (which is always a list of expressions) containing the
│ │ │ │  single expression <code class="inline">0</code>. This means that to match out the name and the list of
│ │ │ │  clauses of any function, you'll need to use a pattern like
│ │ │ │  <code class="inline">?Q(&quot;'@Name'() -&gt; _@_@Body.&quot;)</code>, using a dummy clause whose body is a glob lifted
│ │ │ │  one level.</p><p>To visualize the structure of a syntax tree, you can use the function
│ │ │ │ -<code class="inline">merl:show(T)</code>, which prints a summary.

Use `--plt` to specify which PLT to start from, and\n  `--output_plt` to specify where to put the PLT. Note that files already\n  included in the PLT will be reanalyzed if they depend on the new files.\n  This option only works for BEAM files, not source files.\n\n- **`--apps applications`** - By default, warnings will be reported to all\n  applications given by `--apps`. However, if `--warning_apps` is used, only\n  those applications given to `--warning_apps` will have warnings reported. All\n  applications given by `--apps`, but not `--warning_apps`, will be analysed to\n  provide context to the analysis, but warnings will not be reported for them.\n  For example, you may want to include libraries you depend on in the analysis\n  with `--apps` so discrepancies in their usage can be found, but only include\n  your own code with `--warning_apps` so that discrepancies are only reported in\n  code that you own.\n\n- **`--warning_apps applications`** - This option is typically used when\n  building or modifying a PLT as in:\n\n  ```text\n  dialyzer --build_plt --apps erts kernel stdlib mnesia ...\n  ```\n\n  to refer conveniently to library applications corresponding to the\n  Erlang/OTP installation. This option can also be used during\n  analysis to refer to Erlang/OTP applications. File or directory\n  names can also be included, as in:\n\n  ```text\n  dialyzer --apps inets ssl ./ebin ../other_lib/ebin/my_module.beam\n  ```\n\n- **`--build_plt`** - The analysis starts from an empty PLT and creates a new\n  one from the files specified with `-c` and `-r`. This option only works for\n  BEAM files. To override the default PLT location, use `--plt` or\n  `--output_plt`.\n\n- **`--check_plt`** - Check the PLT for consistency and rebuild it if it is not\n  up-to-date.\n\n- **`-Dname` (or `-Dname=value`)** - When analyzing from source, pass the define\n  to Dialyzer. (\\*\\*)\n\n- **`--dump_callgraph file`** - Dump the call graph into the specified file\n  whose format is determined by the filename extension. Supported extensions\n  are: `raw`, `dot`, and `ps`. If something else is used as filename extension,\n  the default `.raw` format is used.\n\n- **`--error_location column | line`{: #error_location }** - Use a pair\n  `{Line, Column}` or an integer `Line` to pinpoint the location of warnings.\n  The default is to use a pair `{Line, Column}`. When formatted, the line and\n  the column are separated by a colon.\n\n- **`files_or_dirs` (for backward compatibility also as `-c files_or_dirs`)** -\n  Use Dialyzer from the command line to detect defects in the specified files or\n  directories containing `.erl` or `.beam` files, depending on the type of the\n  analysis.\n\n- **`--fullpath`** - Display the full path names of files for which warnings are\n  emitted.\n\n- **`--get_warnings`** - Make Dialyzer emit warnings even when manipulating the\n  PLT. Warnings are only emitted for files that are analyzed.\n\n- **`--help` (or `-h`)** - Print a help message and exit.\n\n- **`-I include_dir`** - When analyzing from source, pass the `include_dir` to\n  Dialyzer. (\\*\\*)\n\n- **`--input_list_file file`** - Analyze the file names that are listed in the\n  specified file (one file name per line).\n\n- **`--no_check_plt`** - Skip the PLT check when running Dialyzer. This is\n  useful when working with installed PLTs that never change.\n\n- **`--incremental`** - The analysis starts from an existing incremental PLT, or\n  builds one from scratch if one does not exist, and runs the minimal amount of\n  additional analysis to report all issues in the given set of apps. Notably,\n  incremental PLT files are not compatible with \"classic\" PLT files, and vice\n  versa. The initial incremental PLT will be updated unless an alternative\n  output incremental PLT is given.\n\n- **`--no_indentation`** - Do not insert line breaks in types, contracts, and\n  Erlang Code when formatting warnings.\n\n- **`--no_spec`** - Ignore functions specs. This is useful for debugging when\n  one suspects that some specs are incorrect.\n\n- **`-o outfile` (or `--output outfile`)** - When using Dialyzer from the\n  command line, send the analysis results to the specified outfile rather than\n  to `stdout`.\n\n- **`--metrics_file file`** - Write metrics about Dialyzer's incrementality (for\n  example, total number of modules considered, how many modules were changed\n  since the PLT was last updated, how many modules needed to be analyzed) to a\n  file. This can be useful for tracking and debugging Dialyzer's incrementality.\n\n- **`--output_plt file`** - Store the PLT at the specified file after building\n  it.\n\n- **`-pa dir`** - Include `dir` in the path for Erlang. This is useful when\n  analyzing files that have `-include_lib()` directives.\n\n- **`--plt plt`** - Use the specified PLT as the initial PLT. If the PLT was\n  built during setup, the files are checked for consistency.\n\n- **`--plt_info`** - Make Dialyzer print information about the PLT and then\n  quit. The PLT can be specified with `--plt(s)`.\n\n- **`--plts plt*`** - Merge the specified PLTs to create the initial PLT. This\n  requires that the PLTs are disjoint (that is, do not have any module appearing\n  in more than one PLT). The PLTs are created in the usual way:\n\n  ```text\n  dialyzer --build_plt --output_plt plt_1 files_to_include\n  ...\n  dialyzer --build_plt --output_plt plt_n files_to_include\n  ```\n\n  They can then be used in either of the following ways:\n\n  ```text\n  dialyzer files_to_analyze --plts plt_1 ... plt_n\n  ```\n\n  or\n\n  ```text\n  dialyzer --plts plt_1 ... plt_n -- files_to_analyze\n  ```\n\n  Notice the `--` delimiter in the second case.\n\n- **`--quiet` (or `-q`)** - Make Dialyzer a bit more quiet.\n\n- **`-r dirs`** - Same as `files_or_dirs`, but the specified directories are\n  searched recursively for subdirectories containing `.erl` or `.beam` files in\n  them, depending on the type of analysis.\n\n- **`--raw`** - When using Dialyzer from the command line, output the raw\n  analysis results (Erlang terms) instead of the formatted result. The raw\n  format is easier to post-process (for example, to filter warnings or to output\n  HTML pages).\n\n- **`--remove_from_plt`** - The information from the files specified with `-c`\n  and `-r` is removed from the PLT. Notice that this can cause a reanalysis of\n  the remaining dependent files.\n\n- **`--src`** - Override the default, which is to analyze BEAM files, and\n  analyze starting from Erlang source code instead.\n\n- **`--statistics`** - Print information about the progress of execution\n  (analysis phases, time spent in each, and size of the relative input).\n\n- **`--verbose`** - Make Dialyzer a bit more verbose.\n\n- **`--version` (or `-v`)** - Print the Dialyzer version and some more\n  information and exit.\n\n- **`-Wwarn`** - A family of options that selectively turn on/off warnings. (For\n  help on the names of warnings, use `dialyzer -Whelp`.) Notice that the options\n  can also be specified in the file with a `-dialyzer()` attribute. For details,\n  see section\n  [Requesting or Suppressing Warnings in Source Files](`m:dialyzer#suppression`).\n\n> #### Note {: .info }\n>\n> \\*\\* the syntax of defines and includes is the same as that used by\n> [erlc](`e:erts:erlc_cmd.md`).\n\n[](){: #warning_options }\n\n_Warning options:_\n\n- **`-Werror_handling` (\\*\\*\\*)** - Include warnings for functions that only\n  return by an exception.\n\n- **`-Wextra_return` (\\*\\*\\*)** - Warn about functions whose specification\n  includes types that the function cannot return.\n\n- **`-Wmissing_return` (\\*\\*\\*)** - Warn about functions that return values that\n  are not part of the specification.\n\n- **`-Wno_behaviours`** - Suppress warnings about behavior callbacks that drift\n  from the published recommended interfaces.\n\n- **`-Wno_contracts`** - Suppress warnings about invalid contracts.\n\n- **`-Wno_fail_call`** - Suppress warnings for failing calls.\n\n- **`-Wno_fun_app`** - Suppress warnings for fun applications that will fail.\n\n- **`-Wno_improper_lists`** - Suppress warnings for construction of improper\n  lists.\n\n- **`-Wno_match`** - Suppress warnings for patterns that are unused or cannot\n  match.\n\n- **`-Wno_missing_calls`** - Suppress warnings about calls to missing functions.\n\n- **`-Wno_opaque`** - Suppress warnings for violations of opacity of data types.\n\n- **`-Wno_return`** - Suppress warnings for functions that will never return a\n  value.\n\n- **`-Wno_undefined_callbacks`** - Suppress warnings about behaviors that have\n  no `-callback` attributes for their callbacks.\n\n- **`-Wno_unused`** - Suppress warnings for unused functions.\n\n- **`-Wno_unknown`** - Suppress warnings about unknown functions and types. The\n  default is to warn about unknown functions and types when setting the exit\n  status. When using Dialyzer from Erlang, warnings about unknown functions and\n  types are returned.\n\n- **`-Wunderspecs` (\\*\\*\\*)** - Warn about underspecified functions (the\n  specification is strictly more allowing than the success typing).\n\n- **`-Wunmatched_returns` (\\*\\*\\*)** - Include warnings for function calls that\n  ignore a structured return value or do not match against one of many possible\n  return values. However, no warnings are included if the possible return values\n  are a union of atoms or a union of numbers.\n\nThe following options are also available, but their use is not recommended (they\nare mostly for Dialyzer developers and internal debugging):\n\n- **`-Woverspecs` (\\*\\*\\*)** - Warn about overspecified functions (the\n  specification is strictly less allowing than the success typing).\n\n- **`-Wspecdiffs` (\\*\\*\\*)** - Warn when the specification is different than the\n  success typing.\n\n> #### Note {: .info }\n>\n> \\*\\*\\* denotes options that turn on warnings rather than turning them off.\n\nThe following options are not strictly needed as they specify the\ndefault. They are primarily intended to be used with the `-dialyzer`\nattribute. For an example see section [Requesting or Suppressing\nWarnings in Source Files](`m:dialyzer#suppression`).\n\n- **`-Wno_underspecs`** - Suppress warnings about underspecified functions (the\n  specification is strictly more allowing than the success typing).\n\n- **`-Wno_extra_return`** - Suppress warnings about functions whose\n  specification includes types that the function cannot return.\n\n- **`-Wno_missing_return`** - Suppress warnings about functions that return\n  values that are not part of the specification.",

That has been made possible by not declaring\n  [`dict:dict()`](`t:dict:dict/0`) as opaque.\n\n  Own Id: OTP-12493\n\n- Update the PLT properly when a module is changed.

One visible change is that the frames are removed.\n\n  Own Id: OTP-8201\n\n- Dialyzer can statically detect some kinds of data races in Erlang programs.\n  Use the new option -Wrace_conditions to enable the race analysis. The\n  technique is described in a paper which is available at:\n  http://www.it.uu.se/research/group/hipe/dialyzer/publications/races.pdf\n\n  Added support for packages (thanks to Maria Christakis).\n\n  There has been a major change in the default mode of Dialyzer. Previously, the\n  default mode was the GUI, while now it is the command line. As a result of\n  this change, it is now possible to analyze a set of files/dirs with the\n  command:\n\n  - dialyzer file1 ... fileN\n\n  In other words, the -c (--command-line) option is no longer necessary, though\n  it will be retained for some time for backwards compatibility. To start\n  dialyzer's GUI use either of the following commands:\n\n  - dialyzer --gui %% for the old gs-based GUI\n  - dialyzer --wx %% for the new wx-based GUI (where available)\n\n  There is a new option --apps which allows the user to easily refer to\n  Erlang/OTP applications and include them in the analysis or in the building of\n  the PLT. For example, we recommend building the PLT with:\n\n  - dialyzer --build_plt --apps erts kernel stdlib mnesia ...\n\n  The new option can also take absolute file names as well as applications. Note\n  that the application versions that will be included in the PLT are those that\n  correspond to the Erlang/OTP system which is used.\n\n  Dialyzer has a new wxWidgets based GUI (thanks to Elli Frangaki) for platforms\n  where the wx application is available.\n\n  Own Id: OTP-8300",

Previous dialyzer versions only accepted this notation\n  in -type and -spec declarations, but effectively ignored its information by\n  mapping remote types to the type any(). In contrast, starting with this\n  version, remote types are used in the analysis and are also stored in the\n  PLTs. (This addition changes the format of PLTs and requires rebuilding any\n  PLTs created by an older dialyzer version.) Note that dialyzer will complain\n  and abort the analysis of a set of modules if it needs to process a remote\n  type without a definition (either because the module does not include a\n  definition of the type or the module is not included in the analysis). We may\n  relax this restriction in a future version.\n\n  Fixed minor issue with dialyzer:run/1 crashing (upon its return) when used for\n  adding type information to an existing PLT.\n\n  Fixed minor but quite annoying issues in dialyzer's GUI.\n\n  Own Id: OTP-8187",

Whenever a function returns a single atomic value (e.g.\n  'ok' or pid()), the warning is suppressed. This allows for \"void\" functions\n  (returning a single atom like 'ok') or for calls to certain builtins like\n  `spawn`.

It is\nrecommended to build a PLT with the Erlang/OTP applications that you are using,\nbut also to include your own applications that you are using frequently.\n\nThe PLT is built using option `--build_plt` to Dialyzer. The following command\nbuilds the recommended minimal PLT for Erlang/OTP:\n\n```text\ndialyzer --build_plt --apps erts kernel stdlib mnesia\n```\n\nDialyzer looks if there is an environment variable called `DIALYZER_PLT` and\nplaces the PLT at this location. If no such variable is set, Dialyzer places the\nPLT in a file called .dialyzer_plt in the\n[`filename:basedir(user_cache, \"erlang\")`](`m:filename#user_cache`) folder. The\nplacement can also be specified using the options `--plt` or `--output_plt`.\n\nInformation can be added to an existing PLT using option `--add_to_plt`. If you\nalso want to include the Erlang compiler in the PLT and place it in a new PLT,\nthen use the following command:\n\n```text\ndialyzer --add_to_plt --apps compiler --output_plt my.plt\n```\n\nThen you can add your favorite application `my_app` to the new PLT:\n\n```text\ndialyzer --add_to_plt --plt my.plt -r my_app/ebin\n```\n\nBut you realize that it is unnecessary to have the Erlang compiler in this one:\n\n```text\ndialyzer --remove_from_plt --plt my.plt --apps compiler\n```\n\nLater, when you have fixed a bug in your application `my_app`, you want to update\nthe PLT so that it becomes fresh the next time you run Dialyzer. In this case,\nrun the following command:\n\n```text\ndialyzer --check_plt --plt my.plt\n```\n\nDialyzer then reanalyzes the changed files and the files that depend on these\nfiles. Note that this consistency check is performed automatically the next\ntime you run Dialyzer with this PLT. Use option `--check_plt` to perform the\nconsistency check without doing any other analysis.\n\nTo get information about a PLT, use the following option:\n\n```text\ndialyzer --plt_info\n```\n\nTo specify which PLT, use option `--plt`.\n\nTo get the output printed to a file, use option `--output_file`.\n\nNote that no warnings are emitted when manipulating the PLT.

This means Dialyzer can find genuine bugs in complex\ncode, and is pragmatic in the face of missing specs or limited information about\nthe codebase, only reporting issues which it can prove have the potential to\ncause a genuine issue at runtime.

│ │ │ │ │          "doc": "Dialyzer infers types for all top-level functions in a module. If the module\nalso has a spec given in the source-code, Dialyzer will compare the inferred\ntype to the spec. The comparison checks, for each argument and the return, that\nthe inferred and specified types overlap — which is to say, the types have at\nleast one possible runtime value in common. Notice that Dialyzer does not check\nthat one type contains a subset of values of the other, or that they are\nprecisely equal: This allows Dialyzer to make simplifying assumptions to\npreserve performance and avoid reporting program flows which could potentially\nsucceed at runtime.\n\nIf the inferred and specified types do not overlap, Dialyzer will warn that the\nspec is invalid with respect to the implementation. However, if they do overlap,\nDialyzer will proceed under the assumption that the correct type for the given\nfunction is the intersection of the inferred type and the specified type (the\nrationale being that the user may know something that Dialyzer itself cannot\ndeduce). One implication of this is that if the user gives a spec for a function\nwhich overlaps with Dialyzer's inferred type, but is more restrictive, Dialyzer\nwill trust those restrictions. This may then generate an error elsewhere that\nfollows from the erroneously restricted spec.\n\n_Examples:_\n\nNon-overlapping argument:\n\n```erlang\n-spec foo(boolean()) -> string().\n%% Dialyzer will infer: foo(integer()) -> string().\nfoo(N) ->\n    integer_to_list(N).\n```\n\nSince the type of the argument in the spec is different from the type that\nDialyzer inferred, Dialyzer will generate the following warning:\n\n```erlang\nsome_module.erl:7:2: Invalid type specification for function some_module:foo/1.\n The success typing is some_module:foo\n          (integer()) -> string()\n But the spec is some_module:foo\n          (boolean()) -> string()\n They do not overlap in the 1st argument\n```\n\nNon-overlapping return:\n\n```erlang\n-spec bar(a | b) -> atom().\n%% Dialyzer will infer: bar(a | b) -> binary().\nbar(a) -> <<\"a\">>;\nbar(b) -> <<\"b\">>.\n```\n\nSince the return value in the spec and the return value inferred by Dialyzer are\ndifferent, Dialyzer will generate the following warning:\n\n```erlang\nsome_module.erl:11:2: Invalid type specification for function some_module:bar/1.\n The success typing is some_module:bar\n          ('a' | 'b') -> <<_:8>>\n But the spec is some_module:bar\n          ('a' | 'b') -> atom()\n The return types do not overlap\n```\n\nOverlapping spec and inferred type:\n\n```erlang\n-spec baz(a | b) -> non_neg_integer().\n%% Dialyzer will infer: baz(b | c | d) -> -1 | 0 | 1.\nbaz(b) -> -1;\nbaz(c) -> 0;\nbaz(d) -> 1.\n```\n\nDialyzer will \"trust\" the spec and using the intersection of the spec and\ninferred type:\n\n```text\nbaz(b) -> 0 | 1.\n```\n\nNotice how the `c` and `d` from the argument to `baz/1` and the `-1` in the\nreturn from the inferred type were dropped once the spec and inferred type were\nintersected. This could result in warnings being emitted for later functions.\n\nFor example, if `baz/1` is called like this:\n\n```text\ncall_baz1(A) ->\n    case baz(A) of\n        -1 -> negative;\n        0 -> zero;\n        1 -> positive\n    end.\n```\n\nDialyzer will generate the following warning:\n\n```text\nsome_module.erl:25:9: The pattern\n          -1 can never match the type\n          0 | 1\n```\n\nIf `baz/1` is called like this:\n\n```text\ncall_baz2() ->\n    baz(a).\n```\n\nDialyzer will generate the following warnings:\n\n```text\nsome_module.erl:30:1: Function call_baz2/0 has no local return\nsome_module.erl:31:9: The call t:baz\n         ('a') will never return since it differs in the 1st argument\n               from the success typing arguments:\n         ('b' | 'c' | 'd')\n```",

This goes a long way to reduce the\n  resistance to changing and refactoring code.\n\n- **Helps guide and speed up the development process** - By focusing on getting\n  the code to pass the tests, the programmer can become more productive, not\n  overspecify or get lost in premature optimizations, and create code that is\n  correct from the very beginning (so-called _test-driven development_; see\n  [Terminology](chapter.md#terminology)).\n\n- **Helps separate interface from implementation** - When writing tests, the\n  programmer may discover dependencies (in order to get the tests to run) that\n  ought not to be there, and which need to be abstracted away to get a cleaner\n  design. This helps eliminate bad dependencies before they spread throughout\n  the code.\n\n- **Makes component integration easier** - By testing in a bottom-up fashion,\n  beginning with the smallest program units and creating a confidence in that\n  they work as they should, it becomes easier to test that a higher-level\n  component, consisting of several such units, also behaves according to\n  specification (known as _integration testing_; see\n  [Terminology](chapter.md#terminology)).\n\n- **Is self-documenting** - The tests can be read as documentation, typically\n  showing both examples of correct and incorrect usage, along with the expected\n  consequences.",

This brief example shows a session\nwhere sequential tracing is used to trace the `dbg` module and the trace itself:\n\n```erlang\n1> dbg:tracer().\n{ok,<0.30.0>}\n2> {ok, Tracer} = dbg:get_tracer().\n{ok,<0.31.0>}\n3> seq_trace:set_system_tracer(Tracer).\nfalse\n4> dbg:tp(dbg, get_tracer, 0, [{[],[],[{set_seq_token, send, true}]}]).\n{ok,[{matched,nonode@nohost,1},{saved,1}]}\n5> dbg:p(all,call).\n{ok,[{matched,nonode@nohost,22}]}\n6> dbg:get_tracer(), seq_trace:set_token([]).\n(<0.25.0>) call dbg:get_tracer()\nSeqTrace [0]: (<0.25.0>) <0.30.0> ! {<0.25.0>,get_tracer} [Serial: {2,4}]\nSeqTrace [0]: (<0.30.0>) <0.25.0> ! {dbg,{ok,<0.31.0>}} [Serial: {4,5}]\n{1,0,5,<0.30.0>,4}\n```\n\nThis session sets the system_tracer to the same process as the\nordinary tracer process (i. e. <0.31.0>) and sets the trace pattern\nfor the function `dbg:get_tracer` to one that has the action of\nsetting a sequential token. When the function is called by a traced\nprocess (all processes are traced in this case), the process gets\n\"contaminated\" by the token and `seq_trace` messages are sent both for\nthe server request and the response. The `seq_trace:set_token([])`\nafter the call clears the `seq_trace` token, which is why no messages\nare sent when the answer propagates via the shell to the console\nport. Otherwise the output would been more noisy.",

│ │ │ │ │          "doc": "When tracing function calls on a group leader process (an I/O process), there is\nrisk of causing a deadlock. This will happen if a group leader process generates\na trace message and the tracer process, by calling the trace handler function,\nsends an I/O request to the same group leader. The problem can only occur if the\ntrace handler prints to the tty using an `m:io` function such as\n[`format/2`](`io:format/2`). Note that when `dbg:p(all, call)` is called, IO\nprocesses are also traced. Here is an example:\n\n```erlang\n%% Using a default line editing shell\n1> dbg:tracer(process, {fun(Msg,_) -> io:format(\"~p~n\", [Msg]), 0 end, 0}).\n{ok,<0.37.0>}\n2> dbg:p(all, [call]).\n{ok,[{matched,nonode@nohost,25}]}\n3> dbg:tp(mymod,[{'_',[],[]}]).\n{ok,[{matched,nonode@nohost,0},{saved,1}]}\n4> mymod: % TAB pressed here\n%% -- Deadlock --\n```\n\nHere is another example:\n\n```erlang\n%% Using a shell without line editing (oldshell)\n1> dbg:tracer(process).\n{ok,<0.31.0>}\n2> dbg:p(all, [call]).\n{ok,[{matched,nonode@nohost,25}]}\n3> dbg:tp(lists,[{'_',[],[]}]).\n{ok,[{matched,nonode@nohost,0},{saved,1}]}\n% -- Deadlock --\n```\n\nThe reason we get a deadlock in the first example is because when TAB is pressed\nto expand the function name, the group leader (which handles character input)\ncalls `mymod:module_info()`. This generates a trace message which, in turn,\ncauses the tracer process to send an IO request to the group leader (by calling\n`io:format/2`). We end up in a deadlock.\n\nIn the second example we use the default trace handler function. This\nhandler prints to the tty by sending IO requests to the `user`\nprocess. When Erlang is started in the oldshell mode, the shell\nprocess will have `user` as its group leader and so will the tracer\nprocess in this example. Since `user` calls functions in `lists` we\nend up in a deadlock as soon as the first IO request is sent.\n\nHere are a few suggestions for avoiding deadlock:\n\n- Do not trace the group leader of the tracer process. If tracing has been\n  switched on for all processes, call `dbg:p(TracerGLPid, clear)` to stop tracing\n  the group leader (`TracerGLPid`).\n  [`process_info(TracerPid, group_leader)`](`process_info/2`) tells you which\n  process this is (`TracerPid` is returned from `dbg:get_tracer/0`).\n- Do not trace the `user` process if using the default trace handler function.\n- In your own trace handler function, call `erlang:display/1` instead of an `io`\n  function or, if `user` is not used as group leader, print to `user` instead of\n  the default group leader. Example: `io:format(user, Str, Args)`.",

Using a trace port significantly\nlowers the overhead imposed by tracing.\n\nTwo trace drivers are currently implemented: the `file` and the `ip`\ntrace drivers.\n\nThe `file` driver sends all trace messages into one or\nseveral binary files, from where they later can be fetched and\nprocessed with the `trace_client/2` function.\n\nThe `ip` driver opens a TCP/IP port listening port. When a client\n(preferably started by calling `trace_client/2` on another Erlang\nnode) connects, all trace messages are sent over the IP network for\nfurther processing by the remote client.\n\nThe `file` trace driver expects a filename or a wrap files\nspecification as parameter. A file is written with a high degree of\nbuffering, which is why there is no guarantee that all are saved in the\nfile in case of a system crash.\n\nA wrap files specification is used to limit the disk space consumed by the\ntrace. The trace is written to a limited number of files each with a limited\nsize. The actual filenames are `Filename ++ SeqCnt ++ Suffix`, where `SeqCnt`\ncounts as a decimal string from `0` to `WrapCnt` and then around again from `0`.\nWhen a trace term written to the current file makes it longer than `WrapSize`,\nthat file is closed, and if the number of files in this wrap trace is as many as\n`WrapCnt` the oldest file is deleted, and a new file is opened to become the\ncurrent. Thus, when a wrap trace has been stopped, there are at most `WrapCnt`\ntrace files saved with a size of at least `WrapSize` (but not much larger),\nexcept for the last file that might even be empty. The default values are\n`WrapSize = 128*1024` and `WrapCnt = 8`.\n\nThe `SeqCnt` values in the filenames are all in the range `0` through `WrapCnt`\nwith a gap in the circular sequence. The gap is needed to find the end of the\ntrace.\n\nIf the `WrapSize` is specified as `{time, WrapTime}`, the current file is closed\nwhen it has been open more than `WrapTime` milliseconds, regardless of it being\nempty or not.\n\nThe `ip` trace driver has a queue of `QueSize` messages waiting to be delivered.\nIf the driver cannot deliver messages as fast as they are produced by the\nruntime system, a special message is sent, which indicates how many messages\nthat are dropped. That message will arrive at the handler function specified in\n`trace_client/3` as the tuple `{drop, N}` where `N` is the number of consecutive\nmessages dropped. In case of heavy tracing, drops are likely to occur, and they\nsurely occur if no client is reading the trace messages. The default value of\n`QueSize` is 200.",

This manual page does not include any\ndocumentation about using the dynamic trace tools of respective platform.\nHowever, the `examples` directory of the `runtime_tools` application contains\ncomprehensive examples of both `d` and `systemtap` programs that will help you\nget started.

By using [`spread_tag/1`](`spread_tag/1`) and\n[`restore_tag/1`](`restore_tag/1`), one can enable or disable spreading of user\ntags to other processes and then restore the previous state of the user tag. The\nTagData returned from this call contains all previous information so the state\n(including any previously spread user tags) will be completely restored by a\nlater call to [`restore_tag/1`](`restore_tag/1`).\n\nThe `m:file` module already spreads tags, so there is no need to manually call\nthis function to get user tags spread to the `efile` driver through that module.\n\nThe most use of this function would be if one, for example, uses the `m:io` module\nto communicate with an I/O-server for a regular file, such as in the following\nexample:\n\n```erlang\nf() ->\n   {ok, F} = file:open(\"test.tst\", [write]),\n   Saved = dyntrace:spread_tag(true),\n   io:format(F, \"Hello world!\", []),\n   dyntrace:restore_tag(Saved),\n   file:close(F).\n```\n\nIn this example, any user tag set in the calling process will be spread to the\nI/O-server when the `io:format/3` call is done.",

Also note\n    that old cross compilation configurations cannot be used without\n    modifications. For more information on cross compiling Erlang/OTP see the\n    `$ERL_TOP/INSTALL-CROSS.md` file.\n  - Support for staged install using\n    [DESTDIR](http://www.gnu.org/prep/standards/html_node/DESTDIR.html).

For more\n    information see the `$ERL_TOP/INSTALL.md` file.\n  - `make install` now by default creates relative symbolic links instead of\n    absolute ones. For more information see the `$ERL_TOP/INSTALL.md` file.\n  - `$ERL_TOP/configure --help=recursive` now works and prints help for all\n    applications with `configure` scripts.\n  - Doing `make install`, or `make release` directly after `make all` no longer\n    triggers miscellaneous rebuilds.\n  - Existing bootstrap system is now used when doing `make install`, or\n    `make release` without a preceding `make all`.\n  - The `crypto` and `ssl` applications use the same runtime library path when\n    dynamically linking against `libssl.so` and `libcrypto.so`. The runtime\n    library search path has also been extended.\n  - The `configure` scripts of `erl_interface` and `odbc` now search for thread\n    libraries and thread library quirks the same way as ERTS do.\n  - The `configure` script of the `odbc` application now also looks for odbc\n    libraries in `lib64` and `lib/64` directories when building on a 64-bit\n    system.\n  - The `config.h.in` file in the `erl_interface` application is now\n    automatically generated in instead of statically updated which reduces the\n    risk of `configure` tests without any effect.\n\n  (Thanks to Henrik Riomar for suggestions and testing)\n\n  (Thanks to Winston Smith for the AVR32-Linux cross configuration and testing)\n\n  \\*** POTENTIAL INCOMPATIBILITY \\***\n\n  Own Id: OTP-8323\n\n- Cleanups suggested by tidier and modernization of types and specs.\n\n  Own Id: OTP-8455",

Autostart \"jobs\" can now be done in parallel,\n  allowing for some jobs to hang waiting for some parts of the traced system to\n  become ready before proceeding. Previously when using named meta-match-specs\n  (tpm_ms) ending up with zero match-specs still kept the meta trace pattern\n  active. This caused zero match-specs to be equal to unlimited meta tracing on\n  that particular function. If the internal database becomes empty of meta match\n  specs, meta trace pattern is removed for that function. Standard public loop\n  data in the inviso runtime meta tracer process is now extended to a 2-tuple.\n  The functions ctp/1 and ctpl/1 are added making it possible to remove trace\n  patterns for a list of functions rather than one by one. Inviso_rt_meta will\n  now accept a list of binaries to be output into the trace information file, in\n  additions to a single binary. Further it is also possible to make own output\n  to the trace information file using the write_ti/1 function. An error was\n  discovered in inviso_rt making the inviso_rt_meta remain rather than terminate\n  if the inviso_rt terminated due to \"running alone\" (not allowed to run without\n  a control component).
