Can't decompress lz4 file

[rafaelzimmermann]

I can't decompress any file and the unit test from the project is not passing.

System: OSX 10.10.5 Python 2.7.10

.Unable to load blockDict. Possibly not a lz4 file.

Interesting. I haven't been able to test it on OSX. I may have to re-work some of the code to make it compatible. I’ll take a look at it tonight when I get off of work. V/R, Chris

Sorry for the late reply, I'm looking around but I don't have anything running OSX, and I currently don't know anyone who does that I can test this on. I know this is working properly on linux, however without an OSX system to run tests on and t/s I'm not sure there's much I can do... sorry. I'm looking into getting a VM running a hackentosh derivative as an alternative.

V/R, Chris

Hi, I would like to report the same issue. I have installed lz4tools using pip at Mac OS and I keep gettings this:

>>> import lz4tools
>>> lz4tools.compressFileDefault('README.rst')
>>> lz4tools.compressFileDefault('README.rst.lz4')
>>> lz4tools.compressFileDefault('build.tar')
>>> file = lz4tools.openTar('build.tar.lz4')
Unable to load blockDict. Possibly not a lz4 file.
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "lz4tools/__init__.py", line 134, in openTar
    return Lz4Tar.lz4open(name, 'r', fileObj)
  File "lz4tools/lz4tar.py", line 21, in lz4open
    raise ReadError('Not a lz4 file')
NameError: global name 'ReadError' is not defined

I still haven't had a chance to get a hold of something running OSX. If one of you gets a chance to read this, could you please run ./lz4toolsCli README.rst then send me the resulting README.rst.lz4. I'll use that a a baseline to figure out what I can do for OSX.

@darkdragn Here is the output for the command. README.rst.lz4.zip

Sorry for the late response. Thank you very much for taking a look at it. /cc @bixu

@rafaelzimmermann https://github.com/rafaelzimmermann Thanks for posting the results. I'll take a look, and see what I can do about this as soon as I get off of work. ^_^
