2015-12-16Update preloaded modulesBjörn Gustavsson
2015-12-16erl_prim_loader doc: Remove mention of user supplied loaderBjörn Gustavsson
Custom loaders are no longer supported. Most of the documentation for them were removed in c8a7d2d7.
2015-12-16erl_prim_loader: Clean up string_match()Björn Gustavsson
Part of the return value for string_match/3 is not used by its only caller. Eliminate the unused part of the return value and the accumulator argument for string_match().
2015-12-16erl_prim_loader: Avoid making absolute pathsBjörn Gustavsson
We don't need absolute paths unless we are dealing with archives. Since it is not free to turn a relative path absolute (we will need a call to prim_file to fetch the current directory), it's better to delay the call to absname/1 until we are sure it's needed.
2015-12-16erl_prim_loader: Clean up splitting of filenamesBjörn Gustavsson
2015-12-16init: Eliminate the concat/1 functionBjörn Gustavsson
There is no need to use the concat/1 function since all arguments that are passed to it have known types.
2015-12-16Clean up start of erl_prim_loaderBjörn Gustavsson
The 'init' module fetches command line parameters and passes them to erl_prim_loader:start/3. The code can be simplified if 'init' calls a new erl_prim_loader:start/0 function that itself fetches the necessary command line parameters. Also remove the documentation for the start() function, since it there is no way that it can be usefully called by a user application. While we are at it, also get rid of '-id' command line parameter, which is fetched and stored but never actually used.
2015-12-16Remove erl_prim_loader:get_files/2Björn Gustavsson
erl_prim_loader:get_files/2 was an optimization introduced before the SMP emulator (that is, before R11). The idea was to use the async threads in the efile driver to read multiple BEAM files from the disk in parallel. In a modern computer with the SMP emulator, loading a BEAM module seems to be more time-consuming than reading it from disk. To optimize loading we would need to load several modules in parallel. We could modify get_files/2 so that it would support parallel loading, but it is cleaner to first remove get_files/2 and then (in a future commit), introduce new functions to support parallel loading.
2015-12-16erl_prim_loader: Remove code for handling OSEBjörn Gustavsson
2015-12-16erl_prim_loader: Break loop/3 into two functions for readabilityBjörn Gustavsson
The deep indentation makes loop/3 difficult to read and maintain. Break out the request handling code into a separate function.
2015-12-16prim_file: Suppress a dialyzer warningBjörn Gustavsson
Kostis Sagonas pointed out that there is a dialyzer warning for constructing an improper list in the following clause: translate_response(?FILE_RESP_N2DATA = X, [<<_:64, _:64, _:64>> | <<>>] = Data) -> {error, {bad_response_from_port, [X | Data]}}; I don't want to change the code to somehow eliminate the warning. An improper list has already been constructed in the efile driver itself, and that would be difficult to fix. Therefore, tell dialyzer to ignore warnings for improper lists in translate_response/2.
2015-12-16Reduce the ludicrous number of arguments for eval_script()Björn Gustavsson
The compact wall of arguments makes it hard to see what is actually happening in eval_script(). Collect the arguments into a record.
2015-12-16Clean up handling of boot_varsBjörn Gustavsson
Expansion of $ROOT in paths are handled specially compared to boot variables. There is no reason $ROOT can't be handled as a boot variable. We can simplify the expansion of boot variables if we spend a little extra effort upfront collecting all boot variables into a map. Make the error checking for -boot_var arguments stricter. Only allow -boot_var followed by exactly two arguments to help users catch errors earlier.
2015-12-16Remove useless 'catch' in start_it/1Björn Gustavsson
The last clause in start_it/1 calls a function in some module. It goes to great length to catch any exception and pass them on unchanged, and if there was a normal return, it will just return the return value. It can been seen that the entire 'catch' construction with the reference trick is totally unnecessary.
2015-12-16Simplify get_flag() and get_flag_list()Björn Gustavsson
The get_flag/3 function which returns a default value if the flag doesn't exist, is implemented in terms of get_flag/2 which throws an exception if the flag doesn't exist. get_flag/3 is frequently used for the flags that don't exist, which means that means that an exception will be generated and catched for no good reason. Reimplement get_flag/3 so that it doesn't have to call get_flag/2 and catch an exception. Eliminate the get_flag/2 function by writing a special purpose function for the only time it's used, that is for retrieving the value for the -root flag. As a side-effect, we will get a nicer error message if there is something wrong with the -root flag. Similarly, simplify get_flag_list/3 and remove get_flag_list/2. We can also eliminate search/3 and use the lists:keyfind/3 BIF instead.
2015-12-16Clean up parsing and lookup of flagsBjörn Gustavsson
The handling of flags has been incrementally messed up over time, leading to convoluted code. Rewrite the parsing and lookup of flags. By using the appropriate data structures, the code will become simpler.
