2011-11-17Handle upgrade from pre R15 to post R15 saslSiri Hansen
New emulator upgrade mechanism introduced in R15 can only work if the sasl version to upgrade from is 2.2 or later. I.e. if we are already running at least R15. This commit adds backwards compatiblity for upgrades from earlier versions, meaning that the new code is loaded into the old emulator and code_change is executed - then after all application code is updated, the emulator is restarted with the new erts version. Note that this might cause problems if the new code is compiled with the new emulator and there have been updates to the beam format. If this happens, the workaround is to compile the new code with the old emulator.
2011-11-17Step version of sasl to 2.2 for R15Siri Hansen
This is needed for sasl_SUITE:appup_test to work, therefore we do not wait until release time.
2011-11-17Document upgrade instructions restart_new_emulator and restart_emulatorSiri Hansen
2011-11-17Wait for two restarts in upgrade_restart testSiri Hansen
This is an attempt to correct a failing test case. It the test fails on having restarted only once, we give it another try to see if the second restart will happen.
2011-11-17Add restart_new_emulator instruction to kernel, stdlib and sasl appupsSiri Hansen
The appup files for kernel, stdlib and sasl did not contain any UpFromVsn and DownToVsn. This means that it was not possible to create a relup file with systool:make_relup if any of these applications had changed. This commit adds entries in the appup files for a maximum of two major releases back - all with only one upgrade instruction: restart_new_emulator. The point is to allow relups to be generated, but ensure that no soft upgrade is done for these three applications - i.e. they will always cause a restart of the emulator prior to all other upgrade instructions from other applications. Test cases (appup_test) are added to kernel_SUITE, stdlib_SUITE and sasl_SUITE. These all check that expected versions are matched in the appups, and illegal versions (older than two major releases, or in any other way illegal) do not match. The test is written in a general way where it is assumed that the version of these applications are stepped according the the rule that major releases step the second number, maintenance releases step the third number and patches step the fourth number.
2011-11-17Distinguish restart_new_emulator from restart_emulator in upgrade instructionsSiri Hansen
Earlier, there was only one valid instruction to restart the emulator in an appup/relup script, 'restart_new_emulator'. A new instuction, 'restart_emulator', is now added, and the meaning is as follows: 'restart_new_emulator' is mainly for the core applications (erts, kernel, stdlib and sasl), and it indicates that there is new core functionality in the release and the emulator needs to be restarted before executing the upgrade scripts. If this instruction exists, a temporary release will be created which consists of the new version erts, kernel, stdlib and sasl, and the old versions of all other applications. After restarting the emulator with this temporary release, the rest of the upgrade instructions are executed, including loading of new versions. 'restart_emulator' can be used by any application if a restart of the emulator is needed after the upgrade instructions have been executed. In this case, the emulator will be restarted with the new release (i.e. not a tempoarary one) after all other upgrade instructions for all applications have been excecuted.
2011-11-17Upgrade erts: merge sys.config for tmp release instead of using oldSiri Hansen
The sys.config file used for the temporary release in an erts upgrade is now a hybrid where kernel, stdlib and sasl configuration is taken from the new release, and other configuration is taken from the old release. I.e. similar to how the temporary boot file is created.
2011-11-17Allow regexp for version in .appupSiri Hansen
In order to avoid duplication of upgrade instructions in .appup files, we now allow regular expressions to specify the UpFrom and DownTo versions. To be considered a regular expression, the version identifier must be specified as a binary, e.g. <<"2\\.1\\.[0-9]+">> will match versions 2.1.x, where x is any number.
2011-11-17Restart emulator before running upgrade script when erts is upgradedSiri Hansen
If the version of erts differs between two releases, the release handler automatically adds a 'restart_new_emulator' instruction to the upgrade script (relup). Earlier, this instruction was always added at the end of the upgrade script, causing the following sequence of operations during an upgrade (a bit simplified): 1. suspend processes 2. load new code 3. execute code_change functions 4. resume processes 5. restart emulator with new erts version Obviously, this caused the new code to be loaded into the old emulator and this would fail if the beam format had been changed in the new version of the emulator. To overcome this problem, this commit changes the order of the instructions, so for upgrade with changed erts version we now have: 1. restart emulator with new erts, kernel, stdlib and sasl versions, but old versions of all other applications. 2. suspend processes 3. load new code 4. execute code_change functions 5. resume processes This is implemented by creating a temporary release, including new erts, kernel, stdlib and sasl from the new release and all other applications from the old release. A new boot file for this temporary release is created, which includes a new 'apply' instruction to run release_handler:new_emulator_upgrade/2. Then the emulator is restarted using this boot file - and release_handler:new_emulator_upgrade/2 executes the rest of the upgrade script. For downgrade, the order will be as before: 1. suspend processes 2. execute code_change functions with 'down'-indication 3. load old code 4. resume processes 5. restart emulator with old erts version

2011-10-17Make epp search directory of current file first when including another fileRichard Carlsson
The expected behaviour of a C-style preprocessor (such as Erlang's epp) is to allow a header file to include another header file in the same directory even though that directory is not explicitly in the include path, and even if the actual include path might reference another directory containing a file with the same name. For example, if src/foo.erl explicitly includes "../include/foo.hrl", then foo.hrl should be able to include "bar.hrl" in that same directory even though "../include" might not be in the search path, and even if another file named bar.hrl could be found using the search path it should not override the one in the same directory as foo.hrl. In Erlang, the most common situation is that a user of an installed application includes a main public header file using include_lib ("appname/include/foo.hrl") and that file includes a secondary header file "bar.hrl". However, if it does this using include_lib, it causes a bootstrapping problem - in the build environment for the application itself, the application is not necessarily found by name. On the other hand, if foo.hrl uses a plain include, then bar.hrl might be found when the application is built (if explicit paths are set in the makefils) but not later on when a user includes the main header file of the installed application via include_lib. By making -include always look in the directory of the current file before it uses the search path, this problem is remedied, and include directives behave in a more intuitive way. This completes a partial fix in R11 that only worked for include_lib().

Has to follow the release_targets include for make not to think that a misspelled dictionary is up to date just because the exprecs dependency is.
2011-10-17Move dictionaries into own directory and renameAnders Svensson
Generated files are unchanged but the separation will be especially pleasant when more dictionary files are added as examples. It is still only the rfc3588 and relay dictionaries that are known to the diameter implementation.
2011-10-17Whitespace fixesAnders Svensson
2011-10-17@result_code -> @define in dictionary filesAnders Svensson
The section simply results in generated macros and has nothing specifically to do with result codes. It's still not documented, and neither are the macros generated from @enum, since the generated names are typically so long as to be impractical/unreadable in source. Better to use numeric values with a comment or define your own shorter macros as the need arises.
