Include the ability to open a SASL error log file in append mode
at startup vs currently implemented "rewrite-always" mode.

The upgrade instruction 'remove_module' was added in OTP R7B (and
possibly in a patch in R5B or R6B, ticket OTP-3477), and translates to
the low level instruction 'remove', but adds the parameter DepMods
(modules on which Mod is dependent). The ticket says that
"remove_module should be added for symmetry with the add_module
instruction". remove_module was never documented or tested, and it was
never mentioned in a release note. It therefore seems to be low risk
in removing it.
The correct instruction to use when removing a module is
{delete_module,Mod}
which was added in OTP R10B and which is also documented and
tested. This translates to low level instructions 'remove' and 'purge'
i.e. the module is brutally purged after setting the current code to
old. This hardcoded brutal purge is the reason why PrePurge and
PostPurge parameters can not be given with the delete_module
instruction.
The parameter DepMods which was inclued in the remove_module
instruction does not exist for delete_module. From the documentation's
point of view, this is the same for add_module, and thus the two
instructions {add_module,Mod} and {delete_module,Mod} are now
symmetric. However, in the code there is a second instruction for
adding a module, {add_module,Mod,DepMods}, which is not documented. To
add symmetry even for this, {delete_module,Mod,DepMods} is now also
added. Documentation is added for all instructions.

The documentation erroneously specified that clear_alarm/1 would clear
*all* alarms with id AlarmId. This is now corrected according to the
implementation - only the latest received alarm with the given AlarmId
is cleared.

In ref man for appup and in system documentation, design prinsiples,
add a warning related to upgrade when version of erts, kernel, stdlib
or sasl is changed. This will cause an emulator restart where new
version of emulator and core applications will startup together with
old versions of other applications. Care must be taken to avoid
problems due to backwards incompatibility.

Fix confusing documentation about error handlers in SASL
OTP-11507

Conflicts:

The SASL documentation confusingly talks about a handler 'error_logger_mf_h'
which doesn't actually exist. The handler is named 'log_mf_h', and it and
all other error handlers used by SASL are part of stdlib, not SASL itself.
This patch makes the documentation clearer.

rb was only accepting physical filenames as log file.
This patch allow rb to accept now any io_device, valid registered name,
except standard_error which is replaced by standard_io.
Creation of two new exported functions : rb:log_list/0-1
that print in log file if existing, otherwise on standard_io.
Add new functions documentation and tests in rb_SUITE.

Sasl documentation earlier said that the InclApps parameters in a .rel
file defaults to the empty list. This is not correct. It defaults to
the same value as specified in the .app file.

It should not be possible to create a .boot file unless kernel and
stdlib are stated as permanent applications in the .rel file. Note
that 'permanent' is the default start type, so not specifying a start
type for kernel and stdlib is, as always, ok.

Fix typos or minor faults.
Move out code listing of target_system.erl, and use codeinclude

This option will suppress the 'missing-sasl' warning which otherwise
is issued when compiling a .rel file which does not include the sasl
application.

Changes to the mechanism for upgrading the emulator in OTP R15 was
erronously not handled in release_handler:upgrade_app, downgrade_app,
upgrade_script and downgrade_script. This has been corrected,
including test and documentation.

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.

These dependency files was once used when building the documentation,
but are no longer needed.
|
|
This is an extension to which_releases that allows a user to specify the
status of the releases they wish to be returned. For instance it allows
for quickly determining which release is 'permanent' without the need of
parsing the entire release list.

Given this option, all modules that are to be purged by indicated
upgrade,and that can be soft purged, will be purged when all other
check of check_install_release have been successfully completed.
I added a note under install_release in the reference manual about how
to use check_install_release with this new option in order to speed up
the execution of install_release.
I also added three more test cases for this functionality.

This commit utilizes the new bif erlang:check_old_code/1 to check if a
module has old code in the system or not before running
erlang:check_process_code/2. This is to optimize
release_handler:install_release (and
release_handler:check_install_release).
A new test is added which checks that after traversing all
processes/modules once and purging all old code, the second run
through this part of the code is "sufficiently" much faster.
A note is also added in the reference manual for
release_handler:install_release about how to go around the efficiency
problem of this function.
