Some test hosts have e.g. '-' in the name, which causes the node name to have single quotes. This commit updates the suite to handle this correctly.

2013-04-30Fix deep list argument error under Windows in os:cmd/1Aleksandr Vinokurov
Because of leeway in implementing os:cmd/1 under different OS there is a difference in results when calling it with deep list argument. os:cmd/1 specifies io_lib:chars() type for its argument and io_lib functions can produce deep lists inspite of io_lib:chars() result type specification. This commit flattens the argument for erlang:open_port/2 (which is used under Windows) and expands the os_SUITE to regress the bug.

2013-04-17Encode Erlang source files with non-ascii characters in UTF-8Björn Gustavsson
To ensure that 'master' compiles when we merge 'maint' to it, regardless of which encoding is default in 'master', all source files with non-ascii characters *must* have the encoding specified.

2013-04-11Optimize communication with file io serverAnthony Ramine
The file module communicates with a file io server with the following protocol for file operations: > {file_request,From,ReplyAs,Request} < {file_reply,ReplyAs,Reply} The ReplyAs value is sent by the client side to match against when receiving the reply and is otherwise left untouched and passed as is by the server. This commit enables receive optimizations by using the reference of the server monitor, changing the protocol to: > {file_request,From,MonitorRef,Request} < {file_reply,MonitorRef,Reply} As the shape of the messages is not changed, backwards compatibility is not a concern.

2013-02-18Update file_name_SUITEBjörn Gustavsson
Because {prim_file,file}:list_dir/1 no longer returns untranslatable filenames, we must use list_dir_all/1 instead. We also need to use read_link_all/1 instead of read_link/1.

6d516de001dde82c02fe050db8e3aab47914fa90 added prim_file:list_dir_all/1. Unfortunately, only the first element in the list would be handled as intended.
2013-02-13Rethink the filelib:wildcard() functionsBjörn Gustavsson
Commit 70b5e24c9498225fadc08d19503269c8aad851bf broke filelib:wildcard(Pattern, "."). Over the years, the logic for filelib:wilcard() has become a mess of special cases. Probably because of premature optimization, filelib:wildcard(Pattern) and filelib:wildcard(Pattern, Cwd) are handled differently. They can be consolidated if we use a "." as the default Cwd argument. We can also simplify things by compiling the Cwd argument into the wildcard. We did not that in the initial implementation because it used to be possible to pre-compile a wildcard and pass it to filelib:wildcard/{1,2}. Since that is no longer possible, there is no point in keeping the compiled wildcard "portable" (not dependent on the Cwd argument).

2013-02-01Add a new function code:get_mode() can be used to detect how the code ↵Vlad Dumitrescu
servers behaves Rationale: Some applications (like erlide) have code to be loaded dynamically on a node. It may be slow to load everything upfront every time, so if the node is in interactive mode, we would like to just append to the load path. Currently, there is no direct way to detect if the node is running in embedded mode or not so that we can do the right thing.

2013-01-23Fix efile_drv crash when using async thread poolFilipe David Borba Manana
When using the async thread pool and compressed files, when an efile driver port instance is shutdown, the efile_drv stop callback closes the file descriptor (a gzFile instance actually) - this is dangerous if at the same time there's an async thread performing an operation against the file, for example calling invoke_read(), which can result in a segmentation fault, or calling invoke_close() which double closes the gzFile and this in turn causes 2 consecutive calls to driver_free() against same gzFile instance (resulting in later unexpected crashes in erl_bestfit_alloc.c for example). The following test program makes the emulator crash when using the async thread pool: -module(t2). -export([t/1]). t(N) -> file:delete("foo.bar"), % Use of 'compressed' option, for creating/writing the file, % is irrelevant. It only matters when opening it later for % reads - a non-compressed file open with the 'compressed' % option goes through an internal gzFile handle (instead of % a plain integer fd), just like a compressed file. %{ok, Fd} = file:open("foo.bar", [raw, write, binary]), {ok, Fd} = file:open("foo.bar", [raw, write, binary, compressed]), ok = file:write(Fd, <<"qwerty">>), ok = file:close(Fd), Pid = spawn_link(fun() -> process_flag(trap_exit, true), loop(N) end), Ref = erlang:monitor(process, Pid), receive {'DOWN', Ref, _, _, _} -> ok end. loop(0) -> ok; loop(N) -> Server = self(), Pid = spawn(fun() -> {ok, Fd} = file:open("foo.bar", [read, raw, binary, compressed]), Server ! continue, % Comment the file:read/2 call to make the file:close/1 call much % more likely to crash or end up causing efile_drv to close twice % the fd (gzFile), which will make the emulator crash later in the % best fit allocator (erl_bestfit_alloc.c). _ = file:read(Fd, 5), file:close(Fd) end), receive continue -> ok end, exit(Pid, shutdown), loop(N - 1).
