Problem when deserializing a nested object structure

Anonymous — Mon, 26 Oct 2009 17:02:17 -0000

Hi guys,

I'm having a problem when trying to deserialize a nested object structure. The serialization seems to work just fine.

The problem is described here: http://stackoverflow.com/questions/1623795/ruby-yaml-problem-when-deserializing-a-nested-object-structure

If you need any other info, tell me, I will provide it.

Problem with serializing nested (recursed) objects

Kjetil Ørbekk — Tue, 26 Dec 2006 19:19:59 -0000

As discussed on the ruby-talk mailing list (running the code should pretty much explain the problem):

I get this when trying to load an http-access2 object.

yaml2byte has a bug

Anonymous — Fri, 02 Jul 2004 01:59:16 -0000

Hello,
Thanks for your SYCK! ^^
I found a bug!
I compiled syck_0.42 by Borland C++ Compiler 5.5 in
WordowsXP
I found that when I yaml2byte a warning YAML
document, it crashed!
Like this:
---
TEST:
- hello
- world
- {xxx, pp]
TEST2: test: test: test
...

When I run the same program in Linux, syck worked fine!
I traced it,
I found that the problem was in yaml2byte.c, function
syck_yaml2byte(char *yamlstr)

syck_lookup_sym() return 0;

So, it shound modify to

if (syck_lookup_sym( parser, oid, (char **)&sav ) ==
1)
{
ret = S_ALLOC_N( char, strlen( sav->buffer ) +
3 );
ret[0] = '\0';
strcat( ret, "D\n" );
strcat( ret, sav->buffer );
}
else
ret = NULL;

PS: the same problem in Ruby's syck
virtu

nil emited as an empty string

Anonymous — Wed, 21 Jan 2004 21:02:46 -0000

nil is emited as an empty string. This produces
incorrect YAML output.

So YAML::load({nil=>nil}.to_yaml) fails.

Proposed change in yaml/rubytypes.rb:

class NilClass
def is_complex_yaml?
false
end
def to_yaml( opts = {} )
opts[:KeepValue] = true
"~".to_yaml( opts ) # "~" instead of ""
end
end

YAML::Store#new bug?

Anonymous — Thu, 26 Jun 2003 20:15:57 -0000

I was writing a script with yaml4r, and I recently
tested same script for syck-0.35.

I noticed that following code produce a error.

Code:
--
yaml = YAML::Store.new("metadata.yaml", :SortKeys =>
true, :UseBlock => true)
yaml.transaction do
...
end
--

Error:
--
/usr/local/lib/ruby/1.6/pstore.rb:22:in `dirname':

Localization problem with float

Joao Pedrosa — Thu, 19 Jun 2003 03:29:21 -0000

The streaming doesn't respect the localization, i.e., a
number like 31,56 that uses a comma to separated the
decimals in some countries, differently from the
english 31.56 that uses a dot, confuses YAML while
loading the data back.

[dewd@localhost t_]$ ruby -e "require 'gtk2'; require
'yaml'; p 31.5"
31,5

[dewd@localhost t_]$ ruby -e "require 'gtk2'; require
'yaml'; p YAML::load(31.5.to_yaml)"
315

When gtk2 is required it changes the localization.

The country in particular is Brazil and the language is
portuguese.

Thanks,
Joao

syck0.15.tar.gz won't build for python 2.2.x (mkd 9.0, gcc 3

Anonymous — Fri, 18 Apr 2003 04:08:38 -0000

syck 0.5 for python use of YAML -- doesn't build right
(mdk 9.0)

on the strength of this quote from you, info on syck's not
building correctly is appended.
Sounds like a useful tool/metatool, hope it can be
remedied.

======== syck 0.15 README v. 0.8 says:
"""
INSTALLATION

./configure
make
make check
sudo make install

If the unit tests don't pass, notify me immediately. This
distribution
is tested on FreeBSD and Linux. I don't release it unless
the tests
pass on those machines. If tests aren't passing, then
that's a problem.

"""
your email doesn't seem to appear on your page or in
your documentation,
though! trust this will get thru.

=============== PROBLEM ENCOUNTERED DURING
LINUX INSTALL

INSTALLATION

OK but then build goofs up; screen traces appended,
with info on system

Thanks for your help.

PS some more stuff on your page is showing up with
Konqueror than did with
Galeon, including use instead of flex of

[root@ /pya/acqdocs/markupl/YAML_meta]# locate re2c
[root@ /pya/acqdocs/markupl/YAML_meta]#

If that's a pre-requisite, perhaps you could package it
with the rest, since
it's not real common.

Serializing complex node

NAKAMURA, Hiroshi — Tue, 12 Nov 2002 08:31:55 -0000

Attached script causes an error;
src/yaml.y:549:in `_parse':
Parse error at '*str* *:* *FOLD* [FSTART] *RAWTEXT*
*IEND*
*14* *second* *:*' (YAML::Error)
from src/yaml.y:204:in `parse'

from src/emitter.rb:770:in `load'
from digraph-yaml.rb:31

The
version I download is
yamlrb-0.47.tar.rb (but the version in installed
file
is 0.46.)

FYI: to create an empty
object,
lib/soap/mappingRegistry.rb in SOAP4R
might help you.
