The reason the "raw file names" is introduced in the system is to be able to consistently represent file names given in different encodings on the same system. Having the VM automatically translate a file name that is not in UTF-8 when to a list of Unicode characters might seem practical, but this would open up for both duplicate file names and other inconsistent behavior.

But what would happen if we later tried to open the file and has the name as a Unicode list (magically converted from the ISO-latin-1 file name)? The VM will convert the file name given to UTF-8, as this is the encoding expected. Effectively this means trying to open the file named <<"bj�rn"/utf8>>.

To avoid this, we need to differentiate between file names being properly encoded according to the Unicode file naming convention (i.e. UTF-8) and file names being invalid under the encoding.

The ISO-latin-1 name is not valid UTF-8 and one could be tempted to think that automatic conversion in for example <c>file:list_dir/1</c> is a good idea. But what would happen if we later tried to open the file and have the name as a Unicode list (magically converted from the ISO-latin-1 file name)? The VM will convert the file name given to UTF-8, as this is the encoding expected. Effectively this means trying to open the file named <<"bj�rn"/utf8>>. This file does not exist, and even if it existed it would not be the same file as the one that was listed. We could even create two files named "bj�rn", one named in the UTF-8 encoding and one not. If <c>file:list_dir/1</c> would automatically convert the ISO-latin-1 file name to a list, we would get two identical file names as the result. To avoid this, we need to differentiate between file names being properly encoded according to the Unicode file naming convention (i.e. UTF-8) and file names being invalid under the encoding. This is done by representing invalid encoding as "raw" file names, i.e. as binaries.</p> +<p>The core system of Erlang (kernel and stdlib) accepts raw file names except for loadable drivers and executables invoked using <c>open_port({spawn, ...} ...)</c>. <c>open_port({spawn_executable, ...} ...)</c> however does accept them. As mentioned earlier, the arguments given in the option list to <c>open_port({spawn_executable, ...} ...)</c> undergo the same conversion as the file names, meaning that the executable will be provided with arguments in UTF-8 as well. This translation is avoided consistently with how the file names are treated, by giving the argument as a binary.</p> <p>To force Unicode file name translation mode on systems where this is not the default is considered experimental in OTP R14B01 due to the raw file names possibly being a new experience to the programmer and that the non core applications of OTP are not tested for compliance with raw file names yet. Unicode file name translation is expected to be default in future releases.</p> -<p>If working with raw file names, one can still conform to the encoding convention of the Erlang VM by using the <c>file:native_name_encoding/0</c> function, which returns either the atom <c>latin1</c> or the atom <c>utf8</c> depending on the file name translation mode. On Linux, an VM started without explicitly stating the file name translation mode will default to <c>latin1</c> as the native file name encoding, why file names on the disk encoded as UTF-8 will be returned as a list of the names interpreted as ISO-latin-1. The "UTF-8 list" is not a practical type for displaying or operating on in Erlang, but it is backward compatible and usable in all functions requiring a file name. On Windows and MacOSX, the default behavior is that of file name translation, why the <c>file:native_name_encoding/0</c> by default returns <c>utf8</c> on those systems (the fact that Windows actually does not use UTF-8 on the file system level can safely be ignored by the Erlang programmer). The default behavior can be changed using the <c>+fnu</c> or <c>+fnl</c> options to the VM, see the <c>erl</c> command manual page.</p> +<p>If working with raw file names, one can still conform to the encoding convention of the Erlang VM by using the <c>file:native_name_encoding/0</c> function, which returns either the atom <c>latin1</c> or the atom <c>utf8</c> depending on the file name translation mode.

Enforcing the UTF-8 encoding regardless of the mode the Erlang VM is started in might, in some circumstances be a good idea, as the convention of using UTF-8 file names is spreading.</p> </section> <section> diff --git a/lib/stdlib/test/ets_SUITE.erl b/lib/stdlib/test/ets_SUITE.erl index 620848003c..4e789790f6 100644 --- a/lib/stdlib/test/ets_SUITE.erl +++ b/lib/stdlib/test/ets_SUITE.erl @@ -5325,7 +5325,25 @@ my_tab_to_list(_Ts,'$end_of_table', Acc) -> lists:reverse(Acc); my_tab_to_list(Ts,Key, Acc) -> my_tab_to_list(Ts,ets:next(Ts,Key),[ets:lookup(Ts, Key)| Acc]). +wait_for_all_schedulers_online_to_execute() -> + PMs = lists:map(fun (Sched) -> + spawn_opt(fun () -> ok end, + [monitor, {scheduler, Sched}]) + end, + lists:seq(1,erlang:system_info(schedulers_online))), + lists:foreach(fun ({P, M}) -> + receive + {'DOWN', M, process, P, _} -> ok + end + end, + PMs), + ok. + etsmem() -> + %% Wait until it is guaranteed that all already scheduled + %% deallocations of DbTable structures have completed. + wait_for_all_schedulers_online_to_execute(), + AllTabs = lists:map(fun(T) -> {T,ets:info(T,name),ets:info(T,size), ets:info(T,memory),ets:info(T,type)} end, ets:all()), diff --git a/lib/stdlib/vsn.mk b/lib/stdlib/vsn.mk index db7954af04..ac02e1f359 100644 --- a/lib/stdlib/vsn.mk +++ b/lib/stdlib/vsn.mk @@ -1 +1 @@ -STDLIB_VSN = 1.17.2 +STDLIB_VSN = 1.17.3 |
