CHANGES file

Version 3.3.2
(13 November 2014, from /trunk)
http://svn.gna.org/svn/relax/tags/3.3.2


Features

  • Many improvements for the HTML version of the manual.
  • Improved sectioning printouts in the model-free dauvergne_protocol auto-analysis.
  • Significant improvements for the relax controller window.
  • All wizards and user functions in the relax GUI now have focus so that keyboard is active without requiring a mouse click.
  • The ESC key will now close the relax controller window and all user function windows.
  • The structure.load_spins user function can now load spins from multiple non-identical molecules and merge them into one molecule allowing missing atoms and differential atom numbering to be handled.
  • Improvements to the printouts for many user functions.


Changes

  • Updated the minfx version in the release checklist document to version 1.0.11.
  • Updated the relax version in the release checklist document to be more modern.
  • Spelling fixes for the CHANGES file.
  • Updates for the release checklist document. This is mainly because the main release notes are now the relax wiki, for example for the current version at http://wiki.nmr-relax.com/Relax_3.3.1.
  • Spelling fixed throughout the CHANGES document.
  • Removed a few triple spaces in the CHANGES document.
  • Added periods to the end of all items in the CHANGES document.
  • Fix for an 'N/A' in the CHANGES document.
  • Converted a number of single spaces between sentences to double spaces in the CHANGES document.
  • More updates for the announcement section of the release checklist document.
  • The HTML version of the manual is now compiled with Unicode character support. It allows Greek symbols, for example, to be represented as text rather than LaTeX generated PNG images. This fixes titles and massively decreases the number of images required by the HTML pages.
  • Removal of many dual LaTeX and latex2html section titles in the manual. As the HTML manual is now compiled with Unicode support, the Greek characters in the titles are now supported. Therefore in the model-free and the values, gradients, and Hessians chapters, the dual LaTeX and latex2html section titles could be collapsed to the standard LaTeX section title. This will result in better formatting of the manual and its links.
  • Added instructions and a build script for creating a useful version of latex2html. This version is essential for building the HTML version of the manual. The build script downloads the Debian latex2html-2008 sources as well as all Debian patches for latex2html. It then applies a number of patches for fixing and improving the relax documentation. The program is then compiled and can be installed as the root user into /usr/local/.
  • Extended the number of words used in the HTML webpage file names. This is to hopefully prevent files from being overwritten by multiple files having the same name.
  • Added the write out of parameters and χ2 values, when creating a dx_map. Task #7860: When dx_map is issued, create a parameter file which maps parameters to χ2 value.
  • Created system test Relax_disp.test_dx_map_clustered_create_par_file, which must show that relax is not able to find the local minimum under clustered conditions. When creating the map, the map contain χ2 values, which are lower than the clustered fitted values. This should not be the case. Running a larger map with larger bounds and more increments, which should show that there exist a minimum in the minimisation space with a lower χ2 value. Bug #22754: The minimise.calculate() does not calculate χ2 value for clustered residues. Task #7860: When dx_map is issued, create a parameter file which maps parameters to χ2 value.
  • Renamed test scripts and files for producing surface χ2 plots.
  • Renamed sample scripts making surface maps.
  • Added scripts to make surface plots of spin independents parameters δω and Ra2.
  • Added example surface χ2 values for plots. Task #7826: Write an python class for the repeated analysis of dispersion data.
  • Added example save state for more surface plotting.
  • Added boolean argument to dx.map user function, to specify the creation of a parameter and associated χ2 values file. For very very special situations, the creation of this file is not desired.
  • Modified that structure of points in dx.map is always a list of numpy arrays with 3 values.
  • When issuing dx.map user function with points, implemented the writing out of parameter file, with associated calculated χ2 values.
  • Improved the feedback in the User_functions.test_structure_add_atom GUI test. It is now clearer what the input and output data is.
  • The devel_scripts/python_multiversion_test_suite.py script now runs relax with the --time flag. This is for quicker identification of failure points. It will also force the sys.stdout buffer to be flushed more often on Python 2.5 so that it does not appear as if the tests have frozen.
  • Added check to system test Relax_disp.test_cpmg_synthetic_dx_map_points for the creation of a matplotlib surface command plot file.
  • Added the write out of a matplotlib command file, to plot surfaces of a dx map. It uses the minimum χ2 value in the map space, to define surface definitions. It creates a X,Y; X,Z; Y,Z map, where the values in the missing dimension has been cut at the minimum χ2 value. For each map, it creates a projected 3d map of the parameters and the χ2 value, and a heat map for the contours. It also scatters the minimum χ2 value, the 4 smallest χ2 values, and maps any points in the point file, to a scatter point. Mapping the points from file to map points, is done by finding the shortest Euclidean distance in the space from the points to any map points.
  • Fix for testing the raise of expected errors in system tests. The system test will not be tested, if Python version is under version 2.7. Bug #22801: Failure of the relax test suite on Python 2.5.
  • Inserted a z_axis limit for the plotting of 2D surfaces in matplotlib.
  • Added better figure control of χ2 values on z-axis for surface plots.
  • Narrowed in dx_map in system test Relax_disp.test_dx_map_clustered_create_par_file. This is to illustrate the failure of relax finding the global minimum. It seems there is a shallow barrier, which relax failed to climb over, in order to find the minimum value.
  • Added the verbosity argument to the pipe_control.minimise.reset_min_stats() function. All of the minimisation code which calls this now send in their verbosity arguments. This allows the text "Resetting the minimisation statistics." to be suppressed.
  • Added the verbosity argument to the pipe_control.value.set() function. This is passed into the pipe_control.minimise.reset_min_stats() function so its printouts can be silenced.
  • The pipe_control.opendx space mapping code now calls the value.set() function with verbosity=0. This is to silence the very repetitive statistics resetting messages when executing the dx.map user function.
  • Added more checks to the determine_rnd() of the dauvergne_protocol model-free auto-analysis. This is to try to catch bizarre situations such as bug #22730, model-free auto-analysis - relax stops and quits at the polate step. The following additional fatal conditions are now checked for: A file with the same name as the base model directory already exists; The base model directory is not readable; The base model directory is not writable. The last two could be caused by file system corruptions. In addition, the presence of the base model directory is checked for using os.path.isdir() rather than catching errors coming out of the os.listdir() function. These changes should make the analysis more robust in the presence of 'strangeness'.
  • Added an additional check to determine_rnd() of the dauvergne_protocol model-free auto-analysis. This is to try to catch bizarre situations such as bug #22730, model-free auto-analysis - relax stops and quits at the polate step. The additional check is that if the base model directory is not executable, a RelaxError is raised.
  • Added printouts to the determine_rnd() function of the dauvergne_protocol model-free auto-analysis. This is for better user feedback in the log files as to what is happening. It may help in debugging bug #22730: Model-free auto-analysis - relax stops and quits at the polate step.
  • Alphabetical ordering of imports in the dauvergne_protocol model-free auto-analysis.
  • Changed the model-free single spin optimisation title printouts. The specific_analyses.model_free.optimisation.spin_print() function has been deleted. It has instead been replaced by a call to lib.text.sectioning.subtitle(). This is to match the grid search setup title printouts and to differentiate these titles from those printed out by minfx being underlined by '~' characters.
  • Added extensive sectioning printouts to the dauvergne_protocol model-free auto-analysis. The lib.text.sectioning functions title() and subtitle() are now used to mark out all parts of the auto-analysis. This will allow for a much better understanding of the log files produced by this auto-analysis.
  • Complete redesign of the following of text in the relax controller window in the GUI. The current design for some reason no longer worked very often, and there would be many situations where the scrolling to follow the text output would stop and could never be recovered. Therefore this feature has been redesigned. In the LogCtrl element of the relax controller, which displays the relax output messages, the at_end class boolean variable has been introduced. It defaults to True. The following events will turn it off: Arrow keys, Home key, End key, Ctrl-Home key, Mouse button clicks, Mouse wheel scrolling, Window thumbtrack scrolling (the side scrollbar), finding text, the pop up menu 'Go to start', and Select all (menu or Ctrl-A). It will only be turned on in two cases: The pop up menu 'Go to end', and if the caret is on the final line (caused by Ctrl-End, Mouse wheel scrolling, Page Down, Down arrow, Window thumbtrack scrolling, etc.). Three new methods have been introduced to handle certain events: capture_mouse() for mouse button clicks, capture_mouse_wheel() for mouse wheel scrolling, and capture_scroll for window thumbtrack scrolling.
  • Improvements for selecting all text in the relax controller window. Selecting text using the pop up menu or [Ctrl-A] now shifted the caret to line 1 before selecting all text. This deactivates the following of the end of text, if active, as the text following feature causes the text selection to be lost.
  • Modified the behaviour of the relax controller window so that pressing escape closes the window. This involves setting the initial focus on the LogCtrl, and catching the ESC key press in the LogCtrl as well as all relax controller read only wx.Field elements and calling the parent controller handle_close() method.
  • Replaced the hardcoded integer keycodes in the relax controller with the wx variables. This is for the LogCtrl.capture_keys() handler method for dealing with key presses.
  • Improvement for all wizards and user functions in the relax GUI. The focus is now set on the currently displayed page of the wizard. This allows the keyboard to be active without requiring a mouse click. Now text can be instantly input into the first text control and the tab key can jump between elements. As the GUI user functions are wizards with a single page, this is a significant usability improvement for the GUI.
  • The ESC character now closes all wizards and user functions in the relax GUI. By using an accelerator table set to the entire wizard window to catch the ESC keyboard event, the ESC key will cause the _handler_escape() method to be called which then calls the windows Close() method to close the window.
  • Changed the logic for how the new analysis wizard in the GUI is destroyed. This relates to bug #22818, the GUI test suite failures in MS Windows - PyAssertionError: C++ assertion "Assert failure". The Destroy() method has been added to the Analysis_wizard class to properly close all elements of the wizard. This is now called from the menu_new() method of the Analysis_controller class, which is the target of the menu item and toolbar button. To allow the test suite to use this, the menu_new() method now accepts the destroy boolean argument. The test suite can set this to False and then access the GUI elements after calling the method (however the Destroy() method must be called by the test suite).
  • Resign of how the new analysis wizard is handled in the GUI tests. This relates to bug #22818, the GUI test suite failures in MS Windows - PyAssertionError: C++ assertion "Assert failure". The GUI test base class method new_analysis_wizard() has been created to simplify the process. When a new analysis is desired, this method should be called. It will return the analysis page GUI element for use in the test. The method standardises the execution of the new analysis wizard and sets up the analysis in the GUI. It also properly destroys the wizard to avoid the memory leaking issues such as bug #22818. All GUI tests have been converted to use new_analysis_wizard(). This allows the GUI tests to pass on MS Windows. However there are still significant sources of memory leaks (the USER Objects count) visible in the Windows Task Manager.
  • Fix for the gui.fonts module to allow it to be used outside of the GUI.
  • Updated all of the scripts in devel_scripts/gui/. These have been non-functional since the merger of the relax bieri_gui branch back in January 2011.
  • The gui.misc.bitmap_setup() function can now be used outside of the GUI.
  • Fix for the GUI test base class new_analysis_wizard() method for relaxation dispersion analyses.
  • Modified the pipe_control.pipes.get_bundle() function to operate when no pipe is supplied. In this case, the pipe bundle that the current data pipe belongs to will be returned.
  • Created the Periodic_table.has_element() method for the lib.periodic_table module. This is used to simply check if a given symbol exists as an atom in the periodic table.
  • Added 4 unit tests to the _lib.test_periodic_table module for the Periodic_table.has_element() method.
  • Modified the internal structural object backend for the structure.read_pdb user function. The MolContainer._det_pdb_element() method for handling PDB files with missing element information has been updated to use the Periodic_table.has_element() method to check if the PDB atom name corresponds to any atoms in the periodic table. This allows for far greater support for HETATOMS and all of the metals.
  • Created the Structure.test_load_spins_multi_mol system test. This is to test yet to be implemented functionality of the structure.load_spins user function. This is the loading of spin information similar, but not necessarily identical molecules all loaded into the same structural model. For this, the from_mols argument will be added.
  • Fixes for the Structure.test_load_spins_multi_mol system test. The call to the structure.load_spins user function has also been modified so that all 3 spins are loaded at the same time.
  • Implemented the multiple molecule merging functionality of the structure.load_spins user function. The argument has been added to the user function frontend and a description added for this new functionality. In the backend, the pipe_control.structure.main.load_spins() function will now call the load_spins_multi_mol() function if from_mols is supplied. This alternative function is required to handle missing atoms and differential atom numbering.
  • Modified the N_state_model.test_populations system test to test the grid search code paths. This performs a grid search of one increment after minimisation, then switches to the 'fixed' N-state model and performs a second grid search of one increment. This now tests currently untested code paths in the grid_search() API method behind the minimise.grid_search user function. The test demonstrates a bug in the N-state model which was not uncovered in the test suite.
  • Created the N_state_model.test_CaM_IQ_tensor_fit system test. This is for catching bug #22849, the failure of the N-state model analysis when optimising only alignment tensors using RDCs and/or PCSs. This new test checks code paths unchecked in the rest of the test suite, and is therefore of high value.
  • Modified the atomic position handling in pipe_control.structure.main.load_spins_multi_mol(). The multiple molecule merging functionality of the structure.load_spins user function now handles missing atomic positions differently. The aim is that the length of the spin container position variable is fixed for all spins to the number of structures, as the N-state model analysis assumes this equal length for all spins. When data is missing, the atomic position for that structure is now set to None. This will require other modifications in relax to support this new design.
  • Modified the interatom.unit_vectors user function backend to handle missing atomic positions. This is to match the structure.load_spins user function change whereby missing atomic positions are now set to the value of None.
  • Fix for the atomic position handling in pipe_control.structure.main.load_spins_multi_mol(). The dimensionality of the position structure returned by the structural object atom_loop() method needed to be reduced.
  • The structure.load_spins user function now stores the number of states in cdp.N. This is to help the specific analyses which handle ensembles of structures. With the introduction of the from_mols argument to the structure.load_spins user function, the number of states is now not equal to the number of structural models, as the states can now come from different structures of the same model. Therefore the user function will now explicitly set cdp.N to the number of states depending on how the spins were loaded.
  • Clean up and speed up of the N_state_model.test_CaM_IQ_tensor_fit system test. All output files are now set to 'devnull' so that the system test no longer creates any files within the relax source directories. And the optimisation settings have been decreased to hugely speed up the system test.
  • Expanded the lib.arg_check.is_float_matrix() function by adding the none_elements argument. This matches a number of the other module functions, and allows for entire rows of the matrix to be None.
  • Lists of lists containing rows of None are now better supported by the lib.xml functions. The object_to_xml() function will now convert the float parts to IEEE-754 byte arrays, and the None parts will be stored as None in the <ieee_754_byte_array> list node. The matching xml_to_object() function has also been modified to read in this new node format. This affects the results.write and state.save user functions (as well as the results.read and state.load user functions).
  • Added spacing after the minimise.grid_search user function setup printouts. This is for better spacing for the next messages from the specific analysis.
  • Speed up of the N_state_model.test_CaM_IQ_tensor_fit system test. This test is however still far too slow.
  • Added printouts to pipe_control.pcs.return_pcs_data() and pipe_control.rdc.return_rdc_data(). These functions now accept the verbosity argument which if greater than 0 will activate printouts of how many RDCs or PCSs have been assembled for each alignment. This will be useful for user feedback as the spin verses interatomic data container selections can be difficult to understand.
  • The verbosity argument for the N-state model optimisation is now propagated for more printouts. The argument for the calculate() and minimise() API methods is now sent into specific_analyses.n_state_model.optimisation.target_fn_setup(), and from there into the pipe_control.pcs.return_pcs_data() and pipe_control.rdc.return_rdc_data() functions. That way the number of RDCs and PCSs used in the N-state model is reported back to the user for better feedback.
  • Updated the N_state_model.test_CaM_IQ_tensor_fit system test so it operates correctly as a GUI test. All user functions are now executed through the special self._execute_uf() method to allow either the prompt interpreter or the GUI to execute the user function.
  • Modified the N_state_model.test_CaM_IQ_tensor_fit system/GUI test for implementing a new feature. The 'spin_selection' argument has been added to the interatom.define user function. This will be used to carry the spin selections over into the interatomic data containers.
  • Implemented the spin_selection Boolean argument for the interatom.define user function. This has been added to the frontend with a description, and to the backend. When set, it allows the spin selections to define the interatomic data container selection.
  • Changed the spin_selection argument default in the interatom.define user function backend. This now defaults to False to allow other parts of relax which call this function to operate as previously. The default for the interatom.define user function is however still True.
  • Modified the Structure.test_load_spins_multi_mol system test for the spin.pos variable changes. The atomic position for an ensemble of structures is now set to None rather than being missing, so the system test has been updated to check for this.
  • The align_tensor.display user function now has more consistent section formatting. The section() and subsection() functions of the lib.text.sectioning module are now being used to standardise these custom printouts with the rest of relax.
  • Modifications to the new N_state_model.test_CaM_IQ_tensor_fit system test. The system test now checks all of the optimised values to make sure the correct values have been found. That will block any future regressions in this N-state model code path. The system test is now also faster. And the pcs.structural_noise user function RMSD value has been set to 0.0 so that the test no longer has a random component affecting the final optimised values.
  • Added printouts for the rdc.calc_q_factors and pcs.calc_q_factors user functions. These are activated by the new verbosity user function argument which defaults to 1. If the value is greater than 0, then the backend will print out all the calculated Q factors.
  • The verbosity argument of the RDC and PCS q_factors() functions now defaults to 1. This causes the Q factors to be printed out at the end of all N-state model optimisations.
  • Created the Structure.test_bug_22860_CoM_after_deletion system test. This is to catch bug #22860, the failure of the structure.com user function after calling structure.delete.
  • Fix for the checks in the new Structure.test_load_spins_multi_mol system test. A spin index was incorrect.
  • Fix for the structure.load_spins user function when the from_mols argument is used. The load_spins_multi_mol() function of the pipe_control.structure.main module was incorrectly handling the atomic position returned by the internal structural object atom_loop() method. This position is a list of lists when multiple models are present. But when only a single model is present, it returns a simple list.
  • Modified the Structure.test_bug_22860_CoM_after_deletion system test to expect a RelaxNoPdbError. This tests that the structure.com user function raises RelaxNoPdbError after deleting all of the structural information from the current data pipe.
  • The mol_name argument is now exposed in the structure.add_atom user function. This has been added as the first argument of the user function to allow new molecules to be created or to allow the atom to be placed into a specific molecule container. The functionality was already implemented in the backend, so it has been exposed by simply adding a new argument definition to the user function.
  • Created the Structure.test_bug_22861_PDB_writing_chainID_fail system test. This is to catch bug #22861, the chain IDs in the structure.write_pdb user function PDB files are incorrect after calling structure.delete.
  • Small modification of the Structure.test_bug_22861_PDB_writing_chainID_fail system test. File metadata is now being set to demonstrate that the structure.delete user function does not remove this once there is no more data left for the molecule.
  • Small indexing fixes for the dispersion chapter of the relax manual.
  • Fix for system test Relax_disp.test_cpmg_synthetic_dx_map_points. Another import line was written to the matplotlib script.
  • Speedup and fix for system test Relax_disp.test_dx_map_clustered_create_par_file. The following test was taken out, since this a particular interesting case. There exist a double minimum, where relax has not found the global minimum. This is due to not grid searching for Ra2, but using the minimum value.
  • Removed debugging code from the N_state_model.test_CaM_IQ_tensor_fit system test. This was an accidentally introduced state.save user function used to catch the system test state. It would results in the 'x.bz2' file being dumped in the current directory.
  • Loosened the checks in the Relax_disp.test_baldwin_synthetic_full system test. This is to allow the test to pass on Python 2.5 and 3.1 on a 32-bit GNU/Linux system.
  • Fix for the Relax_disp.test_cpmg_synthetic_dx_map_points system test for certain systems. This change is to allow the test to pass on Python 2.5 and 3.1 on a 32-bit GNU/Linux system. This may be related to 32-bit numpy 1.6.2 verses later numpy versions causing precision differences.
  • Fixes for the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test for certain systems. The optimisation precision has been increased, and the value checking precision has been decreased. This change is to allow the test to pass on Python 2.5 and 3.1 on a 32-bit GNU/Linux system. This may be related to 32-bit numpy 1.6.2 verses later numpy versions causing precision differences.
  • Converted all the extern.numdifftools modules using the dos2unix program.
  • Updated the Python 2 to Python 3 migration document to be more current.
  • Small edit of the docs/devel/2to3_checklist document.
  • Expanded the Python 2 to 3 conversion document to list the 2to3 command individually.
  • The ImportErrors in unit tests are now correctly handled by the relax test suite. If an ImportError occurred, this was previously killing the entire test suite.
  • The target_function.relax_fit module unit tests are now skipped if the C module is not compiled.
  • Expanded the Python 2 to 3 conversion document.
  • Small update to the 2to3_checklist document - the print statement conversion has been added.
  • The lib.errors module is now importing lib.compat.pickle for better Python 2 and 3 support. This shifts the compatibility code from lib.errors into lib.compat so that the 2to3 program will not touch the lib.errors module.
  • Better Python 3 compatibility in some test suite shared data profiling scripts. These changes invert the logic, importing the Python 3 builtins module and aliasing xrange() to range(), and passing if an ImporError occurs. The code will now no longer be modified by the 2to3 program.
  • Unicode fixes for the "\u" string in "\usepackage" in the module docstring. This requires escaping as "\\usepackage" to avoid the unicode character '\u'.
  • The lib.check_types module now imports io.IOBase from the lib.compat module. This is to shift more Python 2 vs. 3 compatibility into lib.compat and out of all other modules.
  • Python 3 improvements - changed how the Python 3 absent builtins.unicode() function is handled. The aliased builtins.str() function is now referenced as lib.compat.unicode(). The Python 2 __builtin__.unicode() function is also aliased to lib.compat.unicode(). The GUI using this function now import it from lib.compat.
  • Removed the writable base directory check in the dauvergne_protocol auto-analysis. This check was causing the system test to fail if the user does not have write access to the installed relax directory.
  • Expanded the Mac_framework_build_3way document to include matplotlib.
  • Important bug fix for racing causing the GUI to freeze. This is really only seen in the GUI tests on MS Windows systems, as a user could never be fast enough with the mouse. The GUI interpreter flush() method for ensuring that all user functions in the queue have been cleared now calls wx.Yield() to force all wxPython events to also be flushed. This change will avoid random freezing of the relax test suite.
  • Bug fix for the Mf.test_bug_21615_incomplete_setup_failure GUI test on MS Windows systems. The GUI interpreter flush() method needs to be called between the two structure.load_spins user function calls. Without this, the test will freeze on MS Windows. The freezing behaviour is however not 100% reproducible and is dependent on the Windows version and wxPython version.
  • Shifted a number of wx.NewId() calls to the module namespace to conserve IDs. These are for the menus in the main window and in the spin view window.
  • Shifted the wx.NewId() calls for the spectrum list GUI element to the module namespace. These IDs are used for the pop up menus. The change avoids repetitive calls to wx.NewId() every time a right click occurs, conserving wx IDs so that they are not exhausted when running the test suite or running the GUI for a long time.
  • More shifting of wx.NewId() calls for popup menus to module namespaces to conserve IDs.
  • Converted all of the GUI wizard button IDs to -1, as they are currently unused. This should conserve wx IDs, especially in the test suite.
  • Shifted the main GUI window toolbar button wx IDs to the module namespace. This has no effect apart from better organising the code.
  • Shifted the relax controller window popup menu wx IDs to the module namespace. This is simply to better organise the code to match the other GUI module changes.
  • Menus created by the gui.components.menu.build_menu_item() now default to the wx ID of -1. This is to conserve wx IDs. If the calling code does not provide the ID, there is no need to grab one from the small pool of IDs.
  • Shifted the spin viewer GUI window toolbar button wx IDs to the module namespace. This should conserve wx IDs as the window is created and destroyed, as only 2 IDs will be taken from the small pool for the entire lifetime of the program.
  • Shifted all of the wx.NewId() calls for the new analysis wizard into the module namespace. This will hugely save the number of wx IDs used by the GUI, especially in the test suite. Instead of grabbing 8 IDs from the small pool every time the new analysis wizard is created, only 8 IDs for the lifetime of the program will be used.
  • Another large wx ID saving change. The ID associated with the special accelerator table that allows the ESC button to close relax wizards is now initialised once in the module namespace, and not each time a wizard is created.
  • A small wx ID conserving change - the 'Execute' button in the analysis tabs now uses the ID of -1. A unique ID is not necessary and is unused.
  • The user function class menus no longer have unique wx IDs, as these are unnecessary. This conserves the small pool of unique wx IDs, as the spin viewer window is created and destroyed.
  • Bug fix for the structure.load_spins user function new from_mols argument. This was incorrectly using the pipe_control.pipes.pipe_names() function to obtain its default values in the GUI (although this is not currently uesd). The result was a non-fatal error message on Mac OS X systems of "Python[1065:1d03] *** __NSAutoreleaseNoPool(): Object 0x3a3944c of class NSCFString autoreleased with no pool in place - just leaking".
  • Added a debugging Python version check to the devel_scripts/memory_leak_test_relax_fit.py script. This prevents the script from being executed with a normal Python binary.
  • Created the blacklisted Noe.test_noe_analysis_memory_leaks GUI test. This long test can be manually run to help chase down memory leaks. This can be monitored using the MS Windows task manager, once the 'USER Objects' column is shown. If the USER Objects count reaches 10,000 in Windows, then no more GUI elements can be created and the user will see errors.
  • Added a printout to the Noe.test_noe_analysis_memory_leaks GUI test to help with debugging.
  • Improved debugging printouts for the Noe.test_noe_analysis_memory_leaks GUI test.
  • Small fix for the GUI analysis deletion method to prevent racing in the GUI tests.
  • Redesigned how wizards are destroyed in the GUI. The relax wizard Destroy() method is now overridden. This allows the buttons in the wizard to be properly destroyed, as well as all wizard pages. This should remove a lot of GUI memory leaks.
  • Created the General.test_new_analysis_wizard_memory_leak blacklisted GUI test. This will be used to check for memory leaks in the new analysis wizard.
  • Removed an unused dictionary from the GUI wizard object.
  • Added a wx.Yield() before destroying the new analysis wizard via menu_new(). This is to avoid racing which can be triggered in the test suite.
