Fixed the #seek inheritance hierarchy mostly by no longer conflating #seek and #sysseek as the same thing. 2. Rename PipeFileDescriptor to FIFOFileDescriptor since it can also be used for special character files. 3. Fix #gets so the peek ahead for multi-byte characters is properly respected; refill the buffer if we don't have enough bytes for peek ahead. 4. Fix important error in #new_open_fd which was using the wrong flag on an FD. When using fcntl on an FD, it is important to use the FD_* flags. Was using O_CLOEXEC instead of FD_CLOEXEC and as a result all child processes were hanging when their read pipe was closed. 5. Handle EPIPE in #write correctly. Also raise an error if we get an error instead of ignoring it. --- kernel/common/io.rb | 98 +++++++++++++++++++++++++++------------------ 1 file changed, 59 insertions(+), 39 deletions(-) diff --git a/kernel/common/io.rb b/kernel/common/io.rb index ff70e2814f..7eb36529b3 100644 --- a/kernel/common/io.rb +++ b/kernel/common/io.rb @@ -48,9 +48,16 @@ def self.choose_type(fd) case stat.ftype when "file" BufferedFileDescriptor.new(fd, stat) - when "pipe" - PipeFileDescriptor.new(fd) + when "fifo", "characterSpecial" + FIFOFileDescriptor.new(fd, stat) when "socket" + raise "cannot make socket yet" + when "directory" + raise "cannot make a directory" + when "blockSpecial" + raise "cannot make block special" + when "link" + raise "cannot make link" else new(fd, stat) end @@ -82,7 +89,7 @@ def self.new_open_fd(new_fd) if new_fd > 2 flags = FFI::Platform::POSIX.fcntl(new_fd, F_GETFD, 0) Errno.handle("fcntl(2) failed") if FFI.call_failed?(flags) - flags = FFI::Platform::POSIX.fcntl(new_fd, F_SETFD, FFI::Platform::POSIX.fcntl(new_fd, F_GETFL, 0) | O_CLOEXEC) + flags = FFI::Platform::POSIX.fcntl(new_fd, F_SETFD, FFI::Platform::POSIX.fcntl(new_fd, F_GETFL, 0) | FD_CLOEXEC) Errno.handle("fcntl(2) failed") if FFI.call_failed?(flags) end @@ -114,7 +121,6 @@ def initialize(fd, stat) end @sync = true - reset_positioning(@stat) # Don't bother to add finalization for stdio @@ -149,7 +155,7 @@ def sync=(value) CLONG_OVERFLOW = 1 << 64 - def sysseek(offset, whence=SEEK_SET) + def lseek(offset, whence=SEEK_SET) ensure_open # FIXME: check +amount+ to make sure it isn't too large @@ -243,12 +249,12 @@ def write(str) continue elsif errno == Errno::EPIPE::Errno if @descriptor == 1 || @descriptor == 2 - return buf_size + return(buf_size) end - else - error = true - break end + + error = true + break end break if error @@ -257,6 +263,8 @@ def write(str) buffer += bytes_written @offset += bytes_written end + + Errno.handle("write failed") if error return(buf_size - left) end @@ -409,7 +417,7 @@ def reset_positioning(stat=nil) end def seek_positioning - @offset = sysseek(0, SEEK_CUR) # find current position if we are reopening! + @offset = lseek(0, SEEK_CUR) # find current position if we are reopening! end private :seek_positioning @@ -454,6 +462,11 @@ def tty?

The code calls #find_type in the scope of the enclosing_module, but there could be a conflict with that method name, numbers of args it takes, its purpose, etc. So a failure here should be rescued and allow the followup code to call #find_type on the FFI class. This was discovered when the ffi-io branch failed to build a native extension. The mkmf.rb gem was doing some logging during the build which caused some code in IO::Select to call IO::Select.class_eval on code to instantiate the Timeval_t struct class. Creating a struct calls #find_type but it was calling it from the scope of mkmf.rb which had its own (completely different!) method named #find_type defined. It threw an ArgumentError because the arity didn't match, but it lead me to this logic error and fix. --- kernel/platform/struct.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/platform/struct.rb b/kernel/platform/struct.rb index 2188b23a69..87e079c21b 100644 --- a/kernel/platform/struct.rb +++ b/kernel/platform/struct.rb @@ -128,7 +128,7 @@ def self.layout(*spec) element_size = type_size = f.size else if @enclosing_module - type_code = @enclosing_module.find_type(f) + type_code = @enclosing_module.find_type(f) rescue nil end type_code ||= FFI.find_type(f) From bde4ef6d63b2f89c98b8d2cd5efd9b7736be62dc Mon Sep 17 00:00:00 2001 From: Chuck Remes Date: Mon, 18 Jan 2016 12:22:22 -0600 Subject: [PATCH 132/188] only allow seeking on 'file' file descriptors and not on fifo or other During a call to IO.reopen a file descriptor was dup2'ed.

However, it didn't work. Turns out that the low-level system read function blocks forever so the closed IO/file descriptor didn't raise as expected. The original C code got around this OS behavior by setting special flags and sending signals to the blocked thread to wake it up. This mechanism was only exposed to the bytecode VM and wasn't available to the Ruby runtime so I had to go this other direction. It's less than ideal but if the long-term plan is to utilize libuv for Rubinius IO then this is a good enough fix. --- kernel/common/io.rb | 33 ++++++++++++++++++++++++++++++--- 1 file changed, 30 insertions(+), 3 deletions(-) diff --git a/kernel/common/io.rb b/kernel/common/io.rb index ef017e5a63..bf3151e5c3 100644 --- a/kernel/common/io.rb +++ b/kernel/common/io.rb @@ -729,7 +729,7 @@ def sysseek(offset, whence=SEEK_SET) end end # class FIFOFileDescriptor - class DirectoryFileDescriptor < FileDescriptor + class DirectoryFileDescriptor < BufferedFileDescriptor end # class DirectoryFileDescriptor class SocketFileDescriptor < FIFOFileDescriptor @@ -2635,7 +2635,9 @@ def read(length=nil, buffer=nil) end str = "" - result = @fd.read(length, str) + emulate_blocking_read do + read_nonblock(length, str) + end if str.empty? && length > 0 str = nil @@ -2660,7 +2662,9 @@ def read_all str = "" begin buffer = "" - @fd.read(nil, buffer) + emulate_blocking_read do + read_nonblock(FileDescriptor.pagesize, buffer) + end str << buffer end until eof? @@ -2722,12 +2726,19 @@ def read_nonblock(size, buffer=nil) buffer = StringValue buffer if buffer + unless @fd.blocking? + @fd.set_nonblock + nonblock_reset = true + end + if str = read_if_available(size) buffer.replace(str) if buffer return str else raise EOFError, "stream closed" end + ensure + @fd.clear_nonblock if nonblock_reset end ## @@ -3328,6 +3339,22 @@ def invalid_descriptor? descriptor == -1 || descriptor.nil? end private :invalid_descriptor? + + def emulate_blocking_read + # Simple wrapper intended to wrap a call to #read_nonblock. + # Loops forever while waiting for data to become available + # just like a blocking read, but avoids blocking on the + # low-level read(2) call.
