Bug#916195: debian stretch

[Marc Rosanes]

For some reason, the system information is reporting that I'm on a 
buster/sid, but actually I'm working with a debian stretch

Bug#916195: Additional information: docker stretch

[Marc Rosanes]

Hi,

Additional information:

This issue has been reproduced on a clean docker with debian:stretch.

Bug#861736: closed by Andreas Tille <ti...@debian.org> (Bug#861736: fixed in nexus 4.3.2-svn1921-5)

[Marc Rosanes]

Hi,

We have found that python-nxs is still affected by problems:

The following piece of code fails on stretch + the lastest nexus from 
unstable:


```
import nxs
f = nxs.open("/tmp/foo.h5", "w5")
f.makegroup('entry', 'NXentry')
f.opengroup('entry')
f.makegroup('g', 'NXcollection')
f.opengroup('g', 'NXcollection')
f.makedata('d', 'float64', shape=(1,))
f.opendata('d')
f.putdata(1.23)
f.closedata()
f.closegroup()
f.flush()
f.close()
```


It fails with the exception:

```
Traceback (most recent call last):
  File "nxs_flush_bug.py", line 12, in 
f.flush()
  File "/usr/lib/python2.7/dist-packages/nxs/napi.py", line 397, in flush
raise NeXusError, "Could not flush NeXus file %s"%(self.filename)
nxs.napi.NeXusError: Could not flush NeXus file /tmp/foo.h5
```


The same code works correctly on a clean jessie docker.

This ticket should be reopened, till this issue is solved.

Bug#861736: Bug on NeXus library

[Marc Rosanes]

Additional information:

Storing using 'w' format (hdf4), instead of using 'w5' format (hdf5); 
the error does not appear:


import nxs
e = nxs.NXentry(name= "NXtomo")
e.save("filenamenxs.h5",*'**w**'*)

Bug#861736: python-nxs: Cannot save files with nxs python module

[Marc Rosanes]

Package: python-nxs
Version: 4.3.2-svn1921-4
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?

   Run the following python code:

   import nxs
   e = nxs.NXentry(name= "NXtomo")
   e.save("filenamenxs.h5", 'w5')


   * What was the outcome of this action?

   Got the following exception:

NeXusError
Traceback (most recent call last)
 in ()
> 1 e.save("filenamenxs.h5", 'w5')

/usr/lib/python2.7/dist-packages/nxs/tree.pyc in save(self, filename, 
format)

866 root = NXroot(NXentry(self))
867 if root.nxfile: root.nxfile.close()
--> 868 file = NeXusTree(filename, format)
869 file.writefile(root)
870 file.close()

/usr/lib/python2.7/dist-packages/nxs/napi.pyc in __init__(self, 
filename, mode)

318 else:
319 op = 'create'
--> 320 raise NeXusError, "Could not %s %s"%(op,filename)
321 self.isopen = True
322


   * What outcome did you expect instead?

An hdf5 file filenamenxs.h5 saved with no exception.

Note: Tried this with debian:stable docker and it worked correctly.
