[BUG] rb_update_max_fd: invalid fd (4) given

Added by chris.frederick (Chris Frederick) almost 11 years ago. Updated over 4 years ago.

Status:

Closed

Assignee:

Target version:

ruby -v:

ruby 2.0.0p195 (2013-05-14) [i386-mingw32]

Backport:

[ruby-core:55750]

Description

=begin

Note that I expect EINVAL when running this code. Most of the time it is correctly handled by the rescue on line 108. Occasionally, however, Ruby crashes.

I was originally experiencing this on 1.9.3p392; I upgraded to 2.0.0p195 but it did not resolve the problem.

The triggering code:

100:# Try an file operation and print a single-character result to stdout.
101:#
102:# block - operation to perform.
103:#
104:# Returns nothing.
105:def try
106: yield
107: print '.'
108:rescue Errno::EINVAL
109: print 'i'
110: sleep 1
111:rescue Errno::ENOENT
112: print 'n'
113: sleep 1
114:rescue Errno::EACCES
115: print 'a'
116: sleep 1
117:rescue Errno::EBADF
118: print 'b'
119: sleep 1
120:rescue Errno::ENETDOWN
121: print 'd'
122: sleep 1
123:rescue Errno::ERANGE
124: print 'r'
125: sleep 1
126:end

...

157:50.times do
158: filebase = 'shakeshake-' + Time.new.to_i.to_s
159: print "\ncreate " ; 50.times { |i| try { File.write('%s_%d' % [filebase, i], 'a' * 100_000) } }
160: print "\nrename " ; 50.times { |i| try { File.rename('%s_%d' % [filebase, i], 'deleteme_%d' % [i]) } }
161: print "\ndelete " ; 50.times { |i| try { File.unlink('deleteme_%d' % [i]) } }
162: puts
163:end

It dies like so:

Maybe because you are on Unix platform and the bug reporter on Win32 platform ! :)
It would be better IMHO to try to reproduce it on win32.

Hello,

I tested this against:

ruby 2.0.0p247 (2013-06-27) [i386-mingw32]
ruby 2.0.0p247 (2013-06-27) [x64-mingw32]

Without failures. OS Windows 7 x64.

Can you test if the following script also fails on latest version?

Thank you.

It does fail in 2.0.0p195.

Running this script against a local filesystem will probably not produce any errors. I am using it to test networked filesystems during network disconnects. My FS will frequently return EINVAL - you won't see any crashes unless that's happening for you too.

It'd be somewhat difficult to replicate my environment. If staring at the code indicated by the stack trace isn't enlightening then let me know what debugging I can perform for you. I can reproduce this about every 15 minutes in our lab.

Backport deleted (~~1.9.3: UNKNOWN, 2.0.0: UNKNOWN~~)

I tested the program on Windows 10 x64 on a network file system while repeatedly disconnecting and reconnecting the physical connection and was not able to reproduce the crash. Can you try again on a supported ruby version and see if the crash still occurs?
