Summary of the changes since 1.6.4:
|
|
|
|
: require
|
|
|
|
Changed to search directories for ".rb" and ".so" at the same time,
|
|
instead of search directories for ".rb" then for ".so". The
|
|
previous behavior had a security risk. [ruby-bugs (PR#140)]
|
|
|
|
Which means, now:
|
|
|
|
require "socket"
|
|
|
|
will find the standard socket.so prior to a socket.rb in the current
|
|
directory.
|
|
|
|
: lib/sync.rb
|
|
: lib/mutex_m.rb
|
|
|
|
Fixed for obj.extend(Sync_m) and obj.extend(Mutex_m).
|
|
|
|
: $SAFE / load
|
|
|
|
Fixed a bug that a file with a tainted filename can be loaded when
|
|
1 <= $SAFE <= 3 and the second argument is true. [ruby-dev:13481]
|
|
|
|
$SAFE = 1
|
|
filename = "foo"
|
|
filename.taint
|
|
load(filename, true)
|
|
#=> true
|
|
|
|
: Regexp
|
|
|
|
Fixed for the following case. [ruby-talk:16233]
|
|
|
|
ruby -e 'puts "OK" if /(.|a)bd/ =~ "cxbd"'
|
|
ruby -e 'puts "OK" if /(a|.)bd/ =~ "cxbd"'
|
|
#=> OK
|
|
|
|
: $SAFE / def
|
|
|
|
Fixed so defining a new method is allowed under $SAFE == 4, which
|
|
previously wasn't.
|
|
|
|
ruby -e '$SAFE = 4; def a; end'
|
|
=> -e:1: Insecure operation `(null)' at level 4 (SecurityError)
|
|
|
|
: IO#ioctl
|
|
|
|
Fixed to accept a Bignum as the second argument.
|
|
|
|
Summary of the changes since 1.6.3:
|
|
|
|
: Hash#replace
|
|
|
|
Fixed so the following code does not fail in core dump.
|
|
|
|
h = { 10 => 100, 20 => 200 }
|
|
h2 = { }
|
|
|
|
h.each { |k, v|
|
|
if (k == 10)
|
|
h.delete(10)
|
|
h2.replace(h) # => Abort core dumped
|
|
end
|
|
}
|
|
|
|
: $SAFE / File::unlink
|
|
|
|
Changed to be forbidden under $SAFE >= 2.
|
|
|
|
: ruby -T4
|
|
|
|
Fixed. ARGV is now properly marked as tainted so ruby -T4 no longer
|
|
fails in SecurityError.
|
|
|
|
: Regexp
|
|
|
|
Fixed. Now \1 .. \9 always mean backreferences, and referring to
|
|
unclosed/unmatched parentheses always fails.
|
|
|
|
: String taint infection
|
|
|
|
Fixed for the following cases. [ruby-dev:13340]
|
|
|
|
# []=
|
|
s1 = "abc"
|
|
s2 = "cde".taint
|
|
s1[0]= s2
|
|
p s1.tainted? # => false
|
|
|
|
# crypt
|
|
s = "abc".taint
|
|
p s.crypt("cd").tainted? # => false
|
|
|
|
# ljust
|
|
s = "abc".taint
|
|
p s.ljust(10).tainted? # => false
|
|
|
|
# rjust
|
|
s = "abc".taint
|
|
p s.rjust(10).tainted? # => false
|
|
|
|
# center
|
|
s = "abc".taint
|
|
p s.center(10).tainted? # => false
|
|
|
|
Now they will all be marked as tainted.
|
|
|
|
: rb_yield_0()
|
|
|
|
Fixed so it adjusts a 1-element array when yielded from C API, as
|
|
well. Previously, the following code produced a wrong result:
|
|
|
|
class X
|
|
include Enumerable
|
|
|
|
def each(&block)
|
|
block.call(1)
|
|
block.call(2)
|
|
block.call(3)
|
|
end
|
|
end
|
|
|
|
x = X.new
|
|
p x.to_a #=> [[1], [2], [3]]
|
|
|
|
Now it properly produces [1, 2, 3].
|
|
|
|
: $SAFE / alias
|
|
|
|
Fixed so aliasing global variables is disallowed under $SAFE == 4.
|
|
((<ruby-dev:13287>))
|
|
|
|
: Open3::popen3
|
|
|
|
Fixed to do exit! instead of exit so the dying process does not
|
|
invoke at_exit. ((<ruby-dev:13170>))
|
|
|
|
: SizedQueue#pop
|
|
|
|
Fixed so the following code does not cause a dead lock.
|
|
((<ruby-dev:13169>))
|
|
|
|
ruby -r thread -e 'q = SizedQueue.new(1); q.push(1);'
|
|
-e 'Thread.new{sleep 1; q.pop}; q.push(1);'
|
|
|
|
: SizedQueue#max=
|
|
|
|
Fixed so it really works. ((<ruby-dev:13170>))
|
|
|
|
: Queue
|
|
: SizedQueue
|
|
|
|
Fixed to rescue ThreadError in case the thread is dead just before
|
|
calling Thread#run. ((<ruby-dev:13194>))
|
|
|
|
: Array#&
|
|
: Array#|
|
|
: Array#uniq
|
|
|
|
Fixed so they do not freeze the elements. ((<ruby-list:29665>))
|
|
|
|
(%w(foo bar) & %w(foo baz))[0].upcase!
|
|
=> -:1:in `upcase!': can't modify frozen string (TypeError)
|
|
|
|
%w(foo bar bar baz).uniq[0].upcase!
|
|
=> -:1:in `upcase!': can't modify frozen string (TypeError)
|
|
|
|
: shell.rb
|
|
|
|
shell.rb 0.6 is newly imported as a standard library, along with
|
|
documents.
|
|
|
|
: forwardable.rb
|
|
|
|
forwardable.rb 1.1 is newly imported as a standard library, along with
|
|
documents.
|
|
|
|
: irb & irb-tools
|
|
|
|
irb and irb-tools are updated to 0.7.4 and 0.7.1, respectively.
|
|
|
|
: Daylight saving time
|
|
|
|
Fixed so it is handled correctly. [ruby-bugs-ja (PR#46)]
|
|
|
|
env TZ=America/Managua ruby -e 'p Time.local(1998,12,1,0,59,59)'
|
|
=> Mon Nov 30 01:59:59 EST 1998
|
|
env TZ=America/Managua ruby -e 'p Time.local(1998,12,1,0,59,59).tv_sec'
|
|
=> 912409199
|
|
|
|
: SIGINFO
|
|
|
|
Support SIGINFO of 4.4BSD. [ruby-bugs-ja (PR#45)]
|
|
|
|
: Modifier rescue
|
|
|
|
Fixed so the following code does not emit a parse error any more.
|
|
((<ruby-dev:13073>)), ((<ruby-dev:13292>))
|
|
|
|
raise "" rescue []
|
|
raise "" rescue (p "foo"; true)
|
|
raise "" rescue -1
|
|
raise "" rescue (-1)
|
|
|
|
: Thread
|
|
|
|
Fixed so the following code does not cause a dead lock any more.
|
|
|
|
Thread.start { Thread.stop }
|
|
sleep
|
|
|
|
=> deadlock 0x40199b58: 2:0 - -:1
|
|
deadlock 0x401a2528: 2:4 (main) - -:2
|
|
-:2:in `sleep': Thread: deadlock (fatal)
|
|
from -:2
|
|
ruby 1.6.3 (2001-03-19) [i586-linux]
|
|
|
|
: Module#const_defined?
|
|
: Module#const_get
|
|
: Module#const_set
|
|
|
|
Fixed so they do not access to anything other than constants.
|
|
((<ruby-dev:13019>))
|
|
|
|
: Marshal.dump
|
|
|
|
Improved so it dumps Float with better precision: "%.12g" -> "%.16g"
|
|
((<ruby-list:29349>))
|
|
|
|
: Fixnum#[]
|
|
|
|
Fixed a bug on the platforms which sizeof(long) > sizeof(int).
|
|
|
|
: Regular Expression
|
|
|
|
Fixed a couple of minor bugs. ((<ruby-talk:13658>)), ((<ruby-talk:13744>))
|
|
|
|
: retry
|
|
|
|
Fixed so the following code works correctly again. ((<ruby-talk:13957>))
|
|
|
|
def WHILE(cond)
|
|
return if not cond
|
|
yield
|
|
retry
|
|
end
|
|
|
|
i=0
|
|
WHILE(i<3) {
|
|
print i
|
|
i+=1
|
|
}

: ((<File::Stat>))#size
|
|
|
|
Fixed to return a correct value for files larger than 1G bytes.
|
|
|
|
File.open("/tmp/1GB", "w") {|f|
|
|
f.seek(2**30-1, 0)

|
|
|
|
Fixed. ((<ruby-dev:12718>))
|
|
|
|

|
|
|
|
Fixed so it does not raise a exception.
|
|
|
|
: recursive malloc problem
|
|
|
|
Fixed by preallocating a buffer for stdio using setvbuf().
|
|
((<ruby-dev:12795>))
|
|
|
|
: ((<File>))#flock
|
|
|
|
Fixed so it does not raise Errno::EACCES when the file to flock is
|
|
already locked. (only applicable to the platforms which lack
|
|
flock())
|
|
|
|
: ((<File::Stat>)).new(filename)
|
|
|
|
Added. ((<ruby-dev:12803>))
|
|
|

|
|
Fixed so a Bignum is properly restored through dump & load.
|
|
|
|
: Universal Naming Convention(UNC) support (win32)
|
|
|
|
Added. Now the UNC form (//host/share) is supported. Use slash
|
|
(`(({/}))') instead of backslash (`(({\}))') for separating
|
|
components.
|
|
|
|
: ((<Dir>)).glob (win32)
|
|
|

Fixed so it works for the current directory as well.
|
