The second argument of ioctl seems to be int in Android.
Android is not a supported platform, but this one-line change allows
ruby to build by Android NDK r20.

* include/ruby/io.h (rb_io_enc_t): add typedef.
* io.c (rb_io_extract_modeenc): export.
|
|
|
|
|

* io.c (io_strip_bom): if the first 2 bytes are 0xFF0xFE, it
should be a little-endian UTF, 16 or 32. [Bug #16099]

This commit makes it so that if the binmode option is given with
any encoding arguments, the reader and writer IO objects are
not set to binary encoding.
Fixes [Bug #12989]
|

When passing `binmode: true` to `IO.pipe`, it should behave the same way
as calling `binmode` on each of the file handles. It should set the
file to binmode *and* set the encoding to binary on the file.
Before this commit, passing `binmode: true` to `IO.pipe` would make
`binmode?` return `true`, but the file's encoding would remain the same
as the default encoding. Passing `binmode: true` should make `binmode?`
return `true` *and* set the encoding to binary.

Just for case. This will suppress the warning of Coverity Scan.
|
| |
|
|
|
|
|

In this case, flush_before_seek is enough.
This change will suppress a warning of Coverity Scan.

"exclusive access mode is not supported" exception has resulted in
empty "rubyheap-*.json" files after test/objspace/test_objspace.rb.

* io.c (rb_io_set_encoding_by_bom): IO#set_encoding_by_bom to set
the encoding by BOM if exists. [Bug #15210]

There is no need to call this function twice in a row since
thread switching won't happen in-between calls to it.

There seems to be a compatibility problems with Rails +
Rack::Deflater; so we revert this incompatibility.
This effectively reverts r65922; but keeps the bugfixes to
better support non-blocking sockets and pipes for future use.

On 64-bit Linux, fstat() needs to fill out a 144 byte struct
while F_GETFL only needs to return 8 bytes.
Fwiw, F_GETFD requires an additional rcu_read_lock and bitmap
check; so it's obviously more expensive than F_GETFL on Linux.
Reduce stack usage of rb_update_max_fd from 184 to 24 bytes.

nogvl_copy_file_range and nogvl_copy_stream_sendfile each
used 344 bytes of stack before this change. Now, they are
inlined into nogvl_copy_stream_func which only uses 200 bytes
of stack.
"struct stat" is 144 bytes on my 64-bit Linux.
Note: this doesn't affect GC (yet) since GVL is released;
but increases safety if called from deep machine stacks.
It will affect GC if Thread::Light is merged.

Reduce the struct to 80 bytes (from 88) on amd64 to reduce
stack use.

Lets admit Windows will always be too different from POSIX-like

Since non-blocking I/O is the default after [Bug #14968],
we will hit it more often and cause more acquisition/release
of GVL to wait on single FD.
This also lets us avoid touching the temporal string locking
as much and lets us clean up some test changes made for
[Bug #14968]

This may fix failures from TestIO#test_recycled_fd_close because
interrupts may be missed due to TOCTOU in other places.
