Importing mantid into vanilla python without properties file

[Peter Peterson]

Easy one to demonstrate. On a system without a Mantid.properties file:

$ python2.4 
Python 2.4.3 (#1, Jun 11 2009, 14:09:37) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from MantidFramework import mtd
Problem loading the configuration file /SNS/users/pf9/Mantid.properties Cannot open file in /SNS/users/pf9/Mantid.properties
Trouble configuring the logging framework Not found

Traceback (most recent call last):

  File "/opt/Mantid/bin/MantidFramework.py", line 959, in ?
    mtd = FrameworkSingleton()
  File "/opt/Mantid/bin/MantidFramework.py", line 956, in FrameworkSingleton
    setattr(__main__, '__mantid__', MantidPyFramework())
  File "/opt/Mantid/bin/MantidFramework.py", line 347, in __init__
    super(MantidPyFramework, self).__init__()
RuntimeError: Unable to parse file: in Facilities.xml

Which prevents Mantid from being initialized.

Convert this to a warning and therefore allow mantid to ignore and continue without a file

[Mathieu Doucet]

(In [6551]) Long overdue one-liner that will make life in pythonland much easier (MANTIDPATH environment variable). Re #1594

[Mathieu Doucet]

(In [6552]) Added installer that allows importing mantid into vanilla python. Set MANTIDPATH first. Re #1594

[Mathieu Doucet]

From your release directory, execute:

python setup.py install

Then make sure your LD_LIBRARY_PATH contains your release directory and that MANTIDPATH is set to your release directory.

[Mathieu Doucet]

(In [6588]) Added MANTIDPATH to the PYTHONPATH so that Mantid finds mantidsimple.py on Windows (TODO: write mantidsimple.py in a reasonable place...). Re #1594

[Mathieu Doucet]

(In [6589]) Added trailing slash to release dir in ConfigService. Adding it to MANTIDPATH is both non-standard and makes other parts of the code break. Re #1594

Bulk move of tickets to iteration 27, if your ticket is essential for Iteration 26 then move it back.

[Roman Tolchenov]

(In [8244]) Fixed the particular issue of python crashing, but it is not clear for me why Mantid should work at all without Mantid.properties file. re #1594

[Martyn Gigg]

In 1.1.9493:

• MantidPlot starts and finds the Facilities.xml file;
• MantidFramework can be imported from vanilla python both in the bin directory and elsewhere
• As far as I am aware the VATES plugins can also find the correct Mantid location.

Signing off as passed.
