Changing argv[0] from emu name to progname if ESCRIPT_NAME was not set caused to many failing scripts, revert that part of the change. See 86f6a9856

2017-05-16Teach erlexec the -emu_type optionBjörn Gustavsson
Add the option -emu_type to start an emulator of a certain type. For exampe, "-emu_type lcnt" will start beam.lcnt.smp. Any string will be accepted after -emu_type. If there is no corresponding emulator, there will be an error similar to: erlexec: The emulator '.../bin/x86_64-unknown-linux-gnu/beam.foo.smp' does not exist. On Windows, there is an undocumented option "-debug". Remove that option, because -emu_type can be used instead.
2017-05-16Let --enable-lock-counter build an additional emulatorBjörn Gustavsson
"./configure --enable-lock-counter" would modify the behavior of the default emulator (usually SMP). To make lock counting more accessible, change --enable-lock-counter to build an additional emulator in the same way as: (cd erts/emulator && make lcnt) (The next commit will make it easier to start the built lock-counter emulator.)

It turned out that the dependencies between Dialyzer and TypEr makes it impractical to have TypEr in a separate repository. Add it back to the OTP repository, but put the Erlang module 'typer' in the dialyzer application.

2017-02-06Implement magic referencesRickard Green
Magic references are *intentionally* indistinguishable from ordinary references for the Erlang software. Magic references do not change the language, and are intended as a pure runtime internal optimization. An ordinary reference is typically used as a key in some table. A magic reference has a direct pointer to a reference counted magic binary. This makes it possible to implement various things without having to do lookups in a table, but instead access the data directly. Besides very fast lookups this can also improve scalability by removing a potentially contended table. A couple of examples of planned future usage of magic references are ETS table identifiers, and BIF timer identifiers. Besides future optimizations using magic references it should also be possible to replace the exposed magic binary cludge with magic references. That is, magic binaries that are exposed as empty binaries to the Erlang software.

2016-12-22escript: Handle symbolic link to a standalone escriptHåkan Mattsson
The code has been rearranged to make use of the actual path "get_default_emulator(scriptname)" to the escript instead of the given one "get_default_emulator(argv[0])". TL;DR Assume a source system with some Erlang applications (app1, app2 etc.) and an escript called "mytool". When generating a standalone target system (with reltool for example), the escript(s) are located in the same top bin directory as "erl". See mytool* below. In such a system the original "mytool" escript is given the extension ".escript" and the file with the same name as the original escript is a copy of the "escript" executable. One purpose of the escript executable is to determine which "erl" to use to start the system. In a standalone system we want it to find the runtime system bundled with the escript(s). This is done by analyzing the path in order to find the "erl" located in the same directory as the escript. A dilemma here is that we do not want to put the top bin directory in the execution path (PATH env var) as we then would cause other Erlang applications to make use of our bundled run-time system. One way of solving this is to choose some suitable bin directory in the execution path (such as /user/local/bin) and put a symbolic link there to our mytool executable. Unfortunately this did not work as the escript executable (in this case called mytool) would try to find "erl" in /usr/local/bin and when it did not find such a file it resorted to use the command "erl" which would find some (unwanted) "erl" in the execution path. My fix solves that problem. ├── bin/ │   ├── erl* (dyn_erl.c) │   ├── mytool* (escript.c) │   ├── mytool.escript* (original mytool escript) │   └── start_clean.boot ├── erts-vsn/ │   └── bin/ │   ├── beam* │   ├── beam.smp* │   ├── erl* │   ├── erl_child_setup* │   ├── erlexec* │   └── inet_gethost* └── lib/ ├── app1-vsn ├── app2-vsn └── ...
