2011-11-23Avoid slow code loading of BEAM code in a hipe-enabled emulatorBjörn Gustavsson
On my Linux computer, building the entire Erlang/OTP system with hipe disabled took about 8 minutes. With hipe enabled, but without any native code, the build took about 23 minutes, i.e. more than 3 times slower. (The computer has 4 cores, and I used 'make -j6'.) On my eight-core Mac (running 'make -j10') there was only a slight slowdown when hipe was enabled. The culprit is hipe_unified_loader:post_beam_load/1, which will be called every time a module is loaded (even if the module contains no native code). If post_beam_load/1 is called in a hipe-enabled emulator, it will block multi-scheduling, even if no work needs to be done. Apparently the cost for blocking multi-scheduling can vary greatly, depending on the operating system and system load. As a quick and conservative fix, don't call post_beam_load/1 unless some native code has been previously loaded.

2011-11-17Fix bug in erts upgrade on windowsSiri Hansen
The service which represents the temporary release during erts upgrade on windows was never deleted. This has been corrected. The service is now renamed just after the emulator restart.
2011-11-17Add release vsn info to erts_vsn_changed warningSiri Hansen
2011-11-17Check for sasl application in systools:make_script and make_relupSiri Hansen
make_script will give warning but allow it make_relup will fail since it is not possible to upgrade if sasl is not included in both releases.
2011-11-17Add syntax check of relup to check_install_release and install_releaseSiri Hansen
This commit adds a check that all instructions in the relup are valid. Earlier, the last part (after point_of_no_return) was not checked before the actual installation started, meaning that if the relup was hand written, there was a potential for crashing the upgrade here.
2011-11-17Add documentation for upgrade from pre R15 to post R15 saslSiri Hansen
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.
