View Source Reltool Release Notes
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.

Reltool 0.8
Improvements and New Features
- A new element, - Opts, can now be included in a- reltuple in the reltool release specific configuration format: {rel, Name, Vsn, RelApps, Opts}.- This supports the use of - {rel, Name, Vsn, RelApps, [{load_dot_erlang, false}]}to prevent the boot script from running the- .erlangfile.- The incompatibilities are as follows: - * The return from - reltool:get_config/1and- reltool:get_config/3includes the new- reltuple for all releases where the- load_dot_erlangoption is set to- false.
 * The return from- reltool:get_config/3includes the new- reltuple for ALL releases if the- InclDefsparameter is set to- true.- * POTENTIAL INCOMPATIBILITY * - Own Id: OTP-15571 
Reltool 0.7.8
Fixed Bugs and Malfunctions
- Reltool would earlier erroneously split paths like - "c:\foo"into- ["c","\foo"]when reading the- $ERL_LIBSvariable on windows. This is now corrected.- Own Id: OTP-15454 
Reltool 0.7.7
Fixed Bugs and Malfunctions
- Improved documentation. - Own Id: OTP-15190 
Reltool 0.7.6
Improvements and New Features
- Calls to - erlang:get_stacktrace()are removed.- Own Id: OTP-14861 
Reltool 0.7.5
Improvements and New Features
- Files generated by - release_handlerand- reltool, which might contain Unicode characters, are now encoded as UTF-8 and written with format "~tp" or "~ts". If the file is to be read by- file:consult/1, an encoding comment is added.- Own Id: OTP-14463 
Reltool 0.7.4
Improvements and New Features

Reltool 0.7.3
Fixed Bugs and Malfunctions
- Fixed xml issues in old release notes - Own Id: OTP-14269 
Reltool 0.7.2
Fixed Bugs and Malfunctions
- Dependencies specified in .app files would earlier only be followed for applications that are included in a 'rel' spec in the reltool config. For other applications, only xref would decide the dependencies. - Some dependency chains would even be missed for applications that are included in a 'rel' spec in the reltool config. E.g. - Application x has y as included application, and y in turn has z as included application. Then z is not included.
- Application x has y in its 'applications' tag in the .app file, and y in turn has z as included application. Then z is not included.
 - These bugs are now corrected. - Own Id: OTP-11993 
Reltool 0.7.1
Improvements and New Features
- Modify the code as motivated by a change of the Erlang Parser ( - undefinedis no longer automatically inserted to the type of record fields without an initializer).- Own Id: OTP-13033 Aux Id: OTP-12719 
Reltool 0.7
Improvements and New Features
- Change license text from Erlang Public License to Apache Public License v2 - Own Id: OTP-12845 
Reltool 0.6.6
Fixed Bugs and Malfunctions
- Fixed a minor typo in an error message from reltool_server. - Own Id: OTP-11977 
Reltool 0.6.5
Fixed Bugs and Malfunctions
- 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) - Own Id: OTP-11591 
- 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) - Own Id: OTP-11592 
- Application upgrade (appup) files are corrected for the following applications: - 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- A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP. - (Thanks to Tobias Schlager) - Own Id: OTP-11744 
Reltool 0.6.4.1
Improvements and New Features
- The encoding of the - notes.xmlfile has been changed from latin1 to utf-8 to avoid future merge problems.- Own Id: OTP-11310 
Reltool 0.6.4
Fixed Bugs and Malfunctions
- Fix receive support in erl_eval with a BEAM module. Thanks to Anthony Ramine. - Own Id: OTP-11137 
Improvements and New Features
- 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! - Own Id: OTP-10988 
- Fix possibly "not owner" error while file copy with reltool. Thanks to Alexey Saltanov. - Own Id: OTP-11099 
Reltool 0.6.3
Improvements and New Features
- Some updates are made to reltool for handling unicode. - Own Id: OTP-10781 
Reltool 0.6.2
Fixed Bugs and Malfunctions
- If incl_condwas set toderivedon module level, then reltool_server would crash with acase_clause. This has been corrected.incl_condon module level now overwritesmod_condon app or sys level as described in the documentation.
- If a relspec in the reltool config does not contain all applications that are listed as{applications,Applications}in a.appfile, then these applications are automatically added when creating the.relfile. For 'included_applications', the behaviour was not the same. I.e. if arelspec in the reltool config did not contain all applications that are listed as{included_applications,InclApplications}in a.appfile, then reltool would fail with reason "Undefined applications" when creating the.relfile. This has been corrected, so bothapplicationsandincluded_applicationsare now automatically added if not already in therelspec.
- The relspecification now dictates the order in which included and used applications (specified in the.appfile asincluded_applicationsandapplicationsrespectively) are loaded/started by the boot file. If the applications are not specified in therelspec, then the order from the.appfile is used. This was a bug earlier reported on systools, and is now also implemented in reltool.
- Instead of only looking at the directory name, reltool now first looks for a
.appfile in order to figure out the name of an application.

Improvements and New Features
- Some examples overflowing the width of PDF pages have been corrected. - Own Id: OTP-10665 
Reltool 0.6.1
Improvements and New Features
- A new sys level configuration parameter - {excl_lib,otp_root}is added. When this is set, the target system will not contain anything from- $OTPROOT. It will only contain a releases directory with rel, script and boot files, and a lib directory with applications found outside of- $OTPROOT(i.e. "your own" applications).- Own Id: OTP-9743 
Reltool 0.6
Fixed Bugs and Malfunctions
- Miscellaneous corrections: - Start of reltool GUI would sometimes crash with a badmatch in reltool_sys_win:do_init. This has been corrected.
- Minor corrections of documentation and type specifications of app() and mod() are done.
- If a module name is duplicated in an app file reltool would return an error. This is now changed to a warning.
- Reltool would earlier not necessarily keep the order of applications as listed in the rel specification in the configuration. This has been corrected.
- 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.
- 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.
- 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.
- 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.
- Status bar now indicates that reltool is working (Processing libraries...) for all configuration changes, and when generating target system.
- Title of dependencies column in app and mod window is changed from "Modules used by others" to "Modules using this".
 - Own Id: OTP-9792 
- 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. - 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. - When loading a new configuration file via the GUI, the old configuration is now completely scratched, and only the new is valid. - * POTENTIAL INCOMPATIBILITY * - Own Id: OTP-9794 
- Some bug fixes related to the handling of escripts: - 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.
- 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.
- Loading config with same escript (source) twice caused reltool to add same module twice. This has been corrected.
- Loading config with same escript (inlined beam) twice caused reltool to fail saying module is included by two different applications. This has been corrected.
- 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.
 - Own Id: OTP-9968 
- Reltool would sometimes generate a .app file containing - {start_phases,undefined}, which would cause an exception in systools at parse time. This has been corrected so reltool now omits the- start_phasesentry if the value is- undefined. (Thanks to Juan Jose Comellas)- In order to align with reltool, sasl will also omit - start_phasesentries with value- undefinedin .script files.- Own Id: OTP-10003 
Improvements and New Features
- 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. - Own Id: OTP-9967 
- As a way of specifying one specific version of an application, the following configuration parameter is added on application level: - {lib_dir,Dir}, Dir = string() - This can be useful if the parent directory of the application directory is not suitable to use as a lib dir on system level. - Own Id: OTP-9977 
Reltool 0.5.7.1
Improvements and New Features
- Added recommendation about - RootDirparameter to- reltool:eval_target_spec/3.- Own Id: OTP-9742 
Reltool 0.5.7
Fixed Bugs and Malfunctions
- 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. - Own Id: OTP-9383 
- 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. - Own Id: OTP-9384 
Reltool 0.5.6
Fixed Bugs and Malfunctions
- The system level option - app_filesis documented to allow the values- keep | strip | all, but it only allowed- keep. This is corrected.- Own Id: OTP-9135 
- Allow the same module name in multiple applications visible to reltool, as long as all but one of the applications/modules are explicitly excluded. (Thanks to Andrew Gopienko and Jay Nelson) - Own Id: OTP-9229 
Reltool 0.5.5
Fixed Bugs and Malfunctions
- 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) - - Code cleanups and simplifications - Fix a bug in the calculation of circular dependencies - Eliminate two dialyzer warnings - Put files alphabetically - Own Id: OTP-9120 
Reltool 0.5.4
Improvements and New Features
- Added function - zip:foldl/3to iterate over zip archives.- Added functions to create and extract escripts. See - escript:create/2and- escript:extract/2.- The undocumented function - escript:foldl/3has been removed. The same functionality can be achieved with the more flexible functions- escript:extract/2and- zip:foldl/3.- Record fields has been annotated with type info. Source files as been adapted to fit within 80 chars and trailing whitespace has been removed. - Own Id: OTP-8521 
- A new escript, called - reltool, has been introduced in order to simplify the usage of the reltool application from makefiles.- 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 Kernel and STDLIB applications are always included as they are mandatory. - 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. - A new - embedded_app_typeoption 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- embedded_app_typeis set to something else than- undefined, all included applications will be included in both the release as well as in the boot script. If the- profileis- embeddedthe- embedded_app_typeoption defaults to- load.- A new function called - reltool:get_status/1has been introduced. It returns status about the configuration in the server.- The API functions that may take - PidOrOptionsas input and actually gets- Optionsdoes now print out warnings.- The internal error handling has been improved. For example - {error,Reason}is always returned in case of errors even when the server dies.- appand- appupfiles has been added as well as a corresponding test suite.- Various cleanups has been made in the code and in the documentation. - Own Id: OTP-8590 
Reltool 0.5.3
Improvements and New Features
- Removed spurious documentation files. - Own Id: OTP-8057 
Reltool 0.5.2
Improvements and New Features
- 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. - Own Id: OTP-8254 
Reltool 0.5.1
Fixed Bugs and Malfunctions
- 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.) - Own Id: OTP-8199 
Reltool 0.5
Improvements and New Features
- The tool is still experimental. Feedback is appreciated. - 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. - Some new functions has been introduced in the - reltoolmodule:- start/1, start_link/1, get_config/3, get_target_spec/1 and eval_target_spec/3.- Some new configuration parameters has been introduced: - profile, incl_sys_filters, excl_sys_filters, incl_app_filters, excl_app_filters, incl_archive_filters, excl_archive_filters, archive_opts, escript and relocatable.- Some parameters have been obsoleted and given new semantics: - 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).- * POTENTIAL INCOMPATIBILITY * - Own Id: OTP-7949 
Known Bugs and Problems
- The application is experimental. Feedback is appreciated.
