The single quote in $\' does not begin an atom. Change the regexp to
treat it just like $\". Previously this code would be incorrectly
highlighted:
foo() ->
Quote = $\',
%% This gets coloured as an atom, not as a comment

* pan/fdmanana/fix_efile_drv_crash:
Fix efile_drv crash when using async thread pool
Alternative solution to the efile_drv crash on exit
OTP-10748
|
|
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).
Running this test when using the async thread pool:
shell> erl +A 4
Erlang R15B03 (erts-5.9.3.1) [source] [64-bit] [smp:4:4] [async-threads:4] [hipe] [kernel-poll:false]
Eshell V5.9.3.1 (abort with ^G)
1> c(t2).
{ok,t2}
2> t2:t(500000).
Segmentation fault (core dumped)
When not using the async thread pool, there are no issues:
shell> erl
Erlang R15B03 (erts-5.9.3.1) [source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.9.3.1 (abort with ^G)
1> c(t2).
{ok,t2}
2> t2:t(500000).
ok
3>
An example stack trace when the crash happens because there's
an ongoing read operation is:
