<h1>1 Reltool Release Notes</h1>
<p>This document describes the changes made to the Reltool system
from version to version. The intention of this document is to
list all incompatibilities as well as all enhancements and
bugfixes for every release of Reltool. Each release of Reltool
thus constitutes one section in this document. The title of each
section is the version number of Reltool.</p>
<h3><a name="idp279137644">1.1

<p>
Own Id: OTP-11977</p>
</li>
</ul>
<h3><a name="idp279141188">1.3
Reltool 0.6.5</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
When adding a regexp to a filter in reltool using
{add,Regexp}, and the existing regexp was undefined,
reltool would crash since it got an improper list. This
has been corrected. (Thanks to Håkan Mattsson)</p>
<p>
Own Id: OTP-11591</p>
</li>
<li>
<p>
Adapted reltool test server to common test usage of
tc_status. (Note that this code is not used by OTP daily
test runs.) (Thanks to Håkan Mattsson)</p>
<p>
Own Id: OTP-11592</p>
</li>
<li>
<p>
Application upgrade (appup) files are corrected for the
following applications: </p>
<p>
<span class="code">asn1, common_test, compiler, crypto, debugger,
dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe,
inets, observer, odbc, os_mon, otp_mibs, parsetools,
percept, public_key, reltool, runtime_tools, ssh,
syntax_tools, test_server, tools, typer, webtool, wx,
xmerl</span></p>
<p>
A new test utility for testing appup files is added to
test_server. This is now used by most applications in
OTP.</p>
<p>

<h3><a name="idp279456476">1.4
Reltool 0.6.4.1</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
The encoding of the <span class="code">notes.xml</span> file has been
changed from latin1 to utf-8 to avoid future merge
problems.</p>
<p>
Own Id: OTP-11310</p>
</li>
</ul>
<h3><a name="idp279458572">1.5
Reltool 0.6.4</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
Fix receive support in erl_eval with a BEAM module.
Thanks to Anthony Ramine.</p>
<p>
Own Id: OTP-11137</p>
</li>
</ul>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Reltool used to fail if an application was mentioned in
the config file which was not found in the file system,
even if the application was explicitly excluded in the
config. This has been changed and will only produce a
warning. If the application is not explicitly excluded it
will still cause reltool to fail. Thanks to Håkan
Mattsson!</p>
<p>
Own Id: OTP-10988</p>
</li>
<li>
<p>
Fix possibly "not owner" error while file copy with
reltool. Thanks to Alexey Saltanov.</p>
<p>
Own Id: OTP-11099</p>
</li>
</ul>
<h3><a name="idp279592788">1.6
Reltool 0.6.3</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Some updates are made to reltool for handling unicode.</p>
<p>
Own Id: OTP-10781</p>
</li>
</ul>
<h3><a name="idp279594628">1.7
Reltool 0.6.2</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
<ul> <li> If <span class="code">incl_cond</span> was set to
<span class="code">derived</span> on module level, then reltool_server would
crash with a <span class="code">case_clause</span>. This has been corrected.
<span class="code">incl_cond</span> on module level now overwrites
<span class="code">mod_cond</span> on app or sys level as described in the
documentation. </li> <li> If a <span class="code">rel</span> spec in the
reltool config does not contain all applications that are
listed as <span class="code">{applications,Applications}</span> in a
<span class="code">.app</span> file, then these applications are
autmatically added when creating the <span class="code">.rel</span> file.
For 'included_applications', the behaviour was not the
same. I.e. if a <span class="code">rel</span> spec in the reltool config did
not contain all applications that are listed as
<span class="code">{included_applications,InclApplications}</span> in a
<span class="code">.app</span> file, then reltool would fail with reason
"Undefined applications" when creating the <span class="code">.rel</span>
file. This has been corrected, so both
<span class="code">applications</span> and <span class="code">included_applications</span> are
now automatically added if not already in the <span class="code">rel</span>
spec. </li> <li> The <span class="code">rel</span> specification now
dictates the order in which included and used
applications (specified in the <span class="code">.app</span> file as
<span class="code">included_applications</span> and <span class="code">applications</span>
respectively) are loaded/started by the boot file. If the
applications are not specified in the <span class="code">rel</span> spec,
then the order from the <span class="code">.app</span> file is used. This
was a bug earlier reported on systools, and is now also
implemented in reltool. </li> <li> Instead of only
looking at the directory name, reltool now first looks
for a <span class="code">.app</span> file in order to figure out the name of
an application. </li> </ul></p>

<h4>Improvements and New Features</h4>
<ul>
<li>
<p> Some examples overflowing the width of PDF pages have
been corrected. </p>
<p>
Own Id: OTP-10665</p>
</li>
</ul>
<h3><a name="idp279522820">1.8
Reltool 0.6.1</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
A new sys level configuration parameter
<span class="code">{excl_lib,otp_root}</span> is added. When this is set,
the target system will not contain anything from
<span class="code">$OTP_ROOT</span>. It will only contain a releases
directory with rel, script and boot files, and a lib
directory with applications found outside of
<span class="code">$OTP_ROOT</span> (i.e. "your own" applications).</p>
<p>
Own Id: OTP-9743</p>
</li>
</ul>
<h3><a name="idp279525596">1.9
Reltool 0.6</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
Miscellaneous corrections: <ul> <li> Start of reltool
GUI would sometimes crash with a badmatch in
reltool_sys_win:do_init. This has been corrected. </li>
<li> Minor corrections of documentation and type
specifications of app() and mod() are done. </li>
<li> If a module name is duplicated in an app file
reltool would return an error. This is now changed to a
warning. </li> <li> Reltool would earlier not
necessarily keep the order of applications as listed in
the rel specification in the configuration. This has been
corrected. </li> <li> Reltool would earlier set the
default for included applications to an empty list if it
was not set in the rel specification in the
configuration. This was correct according to
sasl/systools documentation, but not according to
sasl/systools implementation. We decided to change the
documentation and reltool to use the value of
included_applications from the .app file as default
instead of the empty list, since this seems more
intuitive and since systools always has done the same.
</li> <li> The value of included applications in the
rel specification in the configuration did not overwrite
included_applications in the .app file if it was set to
an empty list. This has been corrected. </li> <li>
Reltool would earlier add load instructions in the
script/boot files for ALL modules in the ebin directory
of an application even if mod_cond was set to app
(include only modules listed in the .app file). This has
been corrected. </li> <li> Reltool would earlier add
start instructions in the script/boot file for included
applications. This has been corrected - included
applications shall only be loaded since the including
application is responsible for starting them. </li>
<li> Status bar now indicates that reltool is working
(Processing libraries...) for all configuration changes,
and when generating target system. </li> <li> Title
of dependecies column in app and mod window is changed
from "Modules used by others" to "Modules using this".
</li> </ul></p>
<p>
Own Id: OTP-9792</p>
</li>
<li>
<p>
Configuration changes via the GUI had a few bugs related
to error handling, rollback and undo. A major re-write of
the reltool_server has been done in order to align the
way reltool_server updates and uses its state and tables
for all different kinds of configuration change. </p>
<p>
All configuration changes (except undo) now cause a
re-read of the file system, meaning that if something has
changed in the file system it will be reflected in the
result of the configuration change.</p>
<p>
When loading a new configuration file via the GUI, the
old configuration is now completely scratched, and only
the new is valid.</p>
<p>
*** POTENTIAL INCOMPATIBILITY ***</p>
<p>
Own Id: OTP-9794</p>
</li>
<li>
<p>
Some bug fixes related to the handling of escripts:
<ul> <li> Reltool could not handle escripts with
inlined applications. This has been corrected. Inlined
applications will be visible in the GUI, but not possible
to include/exclude separately. </li> <li> Loading a
config which contains an escript via the GUI menu did not
produce the same result as when using the same
configuration at reltool start. Paths, version and label
could differ. This has been corrected. </li> <li>
Loading config with same escript (source) twice caused
reltool to add same module twice. This has been
corrected. </li> <li> Loading config with same
escript (inlined beam) twice caused reltool to fail
saying module is included by two different applications.
This has been corrected. </li> <li> Loading config
which in addition to an existing escript also adds
another escript, for which the name sorts before the
existing one, would cause reltool to fail saying
"Application name clash". This has been corrected.
</li> </ul></p>
<p>
Own Id: OTP-9968</p>
</li>
<li>
<p>
Reltool would sometimes generate a .app file containing
<span class="code">{start_phases,undefined}</span>, which would cause an
exception in systools at parse time. This has been
corrected so reltool now omits the <span class="code">start_phases</span>
entry if the value is <span class="code">undefined</span>. (Thanks to Juan
Jose Comellas)</p>
<p>
In order to align with reltool, sasl will also omit
<span class="code">start_phases</span> entries with value <span class="code">undefined</span>
in .script files.</p>
<p>
Own Id: OTP-10003</p>
</li>
</ul>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
A warning list is added to the sys window of the reltool
GUI. This list will continuously show all warnings
produced by the current configuration.</p>
<p>
Own Id: OTP-9967</p>
</li>
<li>
<p>
As a way of specifying one specific version of an
application, the following configuration parameter is
added on application level:</p>
<p>
{lib_dir,Dir}, Dir = string()</p>
<p>
This can be useful if the parent directory of the
application directory is not suitable to use as a lib dir
on system level.</p>

</ul>
<h3><a name="idp279703340">1.10
Reltool 0.5.7.1</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Added recommendation about <span class="code">RootDir</span> parameter to
<span class="code">reltool:eval_target_spec/3</span>.</p>
<p>
Own Id: OTP-9742</p>
</li>
</ul>
<h3><a name="idp279705652">1.11
Reltool 0.5.7</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
If a module was duplicated in the library directories
visible to reltool, and the configuration did not point
out which file to use, then reltool:start would always
fail. A pop-up is added which asks if you want to
continue with a safe and minimal configuration.</p>
<p>
Own Id: OTP-9383</p>
</li>
<li>
<p>
wx would sometimes crash due to an empty radiobox on the
'releases' tab of the system window. This radiobox is
removed, and replaced by a listbox which will always
contain at least kernel and stdlib applications.</p>
<p>
Own Id: OTP-9384</p>
</li>
</ul>
<h3><a name="idp279708652">1.12
Reltool 0.5.6</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
The system level option <span class="code">app_files</span> is documented to
allow the values <span class="code">keep | strip | all</span>, but it only
allowed <span class="code">keep</span>. This is corrected.</p>
<p>
Own Id: OTP-9135</p>
</li>
<li>
<p>
Allow the same module name in multiple applications
visible to reltool, as long as all but one of the
applications/modules are explicitely excluded. (Thanks to
Andrew Gopienko and Jay Nelson)</p>
<p>
Own Id: OTP-9229</p>
</li>
</ul>
<h3><a name="idp279712124">1.13
Reltool 0.5.5</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
The reltool module contained two seriously erroneous
specs which caused bogus warnings when dialyzing reltool
and some correct code of users. These were fixed (specs
for start_link/1 and eval_server/3)</p>
<p>
- Code cleanups and simplifications - Fix a bug in the
calculation of circular dependencies - Eliminate two
dialyzer warnings - Put files alphabetically</p>
<p>
Own Id: OTP-9120</p>
</li>
</ul>
<h3><a name="idp279714532">1.14
Reltool 0.5.4</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Added function <span class="code">zip:foldl/3</span> to iterate over zip
archives.</p>
<p>
Added functions to create and extract escripts. See
<span class="code">escript:create/2</span> and <span class="code">escript:extract/2</span>.</p>
<p>
The undocumented function <span class="code">escript:foldl/3</span> has been
removed. The same functionality can be achieved with the
more flexible functions <span class="code">escript:extract/2</span> and
<span class="code">zip:foldl/3</span>.</p>
<p>
Record fields has been annotated with type info. Source
files as been adapted to fit within 80 chars and trailing
whitespace has been removed.</p>
<p>
Own Id: OTP-8521</p>
</li>
<li>
<p>A new escript, called <span class="code">reltool</span>, has been
introduced in order to simplify the usage of the reltool
application from makefiles.</p>
<p>The handling of applications included in releases has
been improved. Applications that are required to be
started before other applications in a release are now
automatically included in the release. The <span class="code">kernel</span>
and <span class="code">stdlib</span> applications are always included as
they are mandatory.</p>
<p>Applications that are (explicitly or implicitly)
included in a release are now automatically included as
if they were explicitly included with the incl_cond
flag.</p>
<p>A new <span class="code">embedded_app_type</span> option has been
introduced. It is intended to be used for embedded
systems where all included applications must be loaded
from the boot script, as these systems does not utilize
dynamic code loading. If <span class="code">embedded_app_type </span> is set
to something else than <span class="code">undefined</span>, all included
applications will be included in both the release as well
as in the boot script. If the <span class="code">profile</span> is
<span class="code">embedded</span> the <span class="code">embedded_app_type</span> option
defaults to <span class="code">load</span>.</p>
<p>A new function called <span class="code">reltool:get_status/1</span> has
been introduced. It returns status about the
configuration in the server.</p>
<p>The API functions that may take <span class="code">PidOrOptions</span> as
input and actually gets <span class="code">Options</span> does now print out
warnings.</p>
<p>The internal error handling has been improved. For
example <span class="code">{error,Reason}</span> is always returned in case
of errors even when the server dies.</p>
<p><span class="code">app</span> and <span class="code">appup</span> files has been added as
well as a corresponding test suite.</p>
<p>Various cleanups has been made in the code and in the
documentation.</p>

<h3><a name="idp279726492">1.15
Reltool 0.5.3</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Removed spurious documentation files.</p>
<p>
Own Id: OTP-8057</p>

</ul>
<h3><a name="idp279731156">1.16
Reltool 0.5.2</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
The documentation is now built with open source tools
(xsltproc and fop) that exists on most platforms. One
visible change is that the HTML frames are removed.</p>

</ul>
<h3><a name="idp279733212">1.17
Reltool 0.5.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
In the new release of Reltool (0.5) there is a severe bug
that may cause your source files to be deleted. The bug
is triggered when you generate a target system WITH
archive files AND your library directories are given with
absolute paths. (Library directories are given with the
ERL_LIBS environment variable or with the lib_dirs
configuration parameter.)</p>
<p>
Own Id: OTP-8199</p>
</li>
</ul>
<h3><a name="idp279735524">1.18
Reltool 0.5</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
The tool is still experimental. Feedback is appreciated. </p>
<p>
Major improvements of the target system generation has
been performed. Now it is possible to generate a
relocatable target system that does not need to be
re-installed if it is moved to a new location. Archive
files are automatically generated. A detailed
specification of the target system can be generated
without actually creating the target system. Relocatable
escripts are put in the bin directory of the target
system. etc. etc.</p>
<p>
Some new functions has been introduced in the
<span class="code">reltool</span> module: <span class="code">start/1, start_link/1,
get_config/3, get_target_spec/1 and
eval_target_spec/3</span>.</p>
<p>
Some new configuration parameters has been introduced:
<span class="code">profile, incl_sys_filters, excl_sys_filters,
incl_app_filters, excl_app_filters, incl_archive_filters,
excl_archive_filters, archive_opts, escript and
relocatable</span>.</p>
<p>
Some parameters have been obsoleted and given new
semantics: <span class="code">incl_erts_dirs (incl_sys_filters),
excl_erts_dirs (excl_sys_filters), incl_app_dirs
(incl_app_filters), excl_app_dirs (excl_app_filters) and
escripts (escript).</span></p>
