eclipse latest new features
From version 4.1 to version 4.2
-----> eclipse-main FITS separation --------------- The eclipse main library has been through surgery to extract all FITS-related functionalities into a stand-alone library that can be used independently from eclipse. This new library is called 'qfits' and has already reached version 4.1 (version number is independent from eclipse). eclipse users will not notice it, because qfits is always included in the eclipse-main tar file and compiled together with the rest of the library. For developpers, this means a change in the FITS API, for all functions are now prefixed with 'qfits_'. Pixel loading has been made more generic and may be a little slower than in the previous versions. Notice that some assembly has found its way into eclipse: on x86-based systems, swap routines are now hardcoded in assembly language. In the future, the qfits library should stabilize at some point and stay frozen unless there are major changes in the FITS format or new file types we want to support. These changes should be independent from eclipse. Build system ------------ The eclipse build system is the part that identifies your platform and selects the appropriate compilation flags for optimal performance. This system has been extended to support more platforms, more compile options, and should make our life easier for portability issues. eclipse now compiles and runs fine on Darwin systems (BSD-like), which opens the door to the new Mac OS X platform. Documentation ------------- An aging version of the "eclipse developer's guide" has been phased out from the distribution. From a recent survey, it appears that nobody outside ESO is using eclipse's C API for development, so this document was mostly unused. If the need ever appears again for this document, one would have to be produced. Buffer overflows ---------------- A number of possible buffer overflows have been removed from the core library, which does not mean that there are none left. Buffer overflows cause core-dumps at best, security holes at worst. Again: it is a terrible idea to install eclipse with suid root or any kind of high privilege. While this library has received great care about bugs of all kinds, security issues have not been tackled as e.g. system daemons. Bug corrections --------------- Lots of bugs have been fixed in the core libraries. They all have been already released in 4.1.x releases as they have been corrected, though. -----> eclipse-isaac General changes: - All QC products have been corrected to support the latest QC1 requirements from Paranal. Spectroscopy: - isaacp lw_spflat: switched default fit order from 4 to 3, which changes the fit polynomial order from 3 to 2. Imaging: - A new recipe has been added and validated for filtering of the odd-even effect on ISAAC frames. Check out the 'oddeven' recipe in isaacp. - The two dark recipes (dark-ron and dark-avg) have been merged into a single recipe. Some warnings have been added in the output PAF file to stress the fact that measurements are done following a Monte-Carlo methods, so results will slightly vary from one execution to another. Imaging jitter: - An additional QC parameter is now produced by the jitter recipe, called QC.IQ (for Image Quality). This parameter tries to estimate the image quality from all objects that look like stars in the final product. This parameter has been added to the ISAAC QC dictionary, and will now be exported to the QC1 log with other QC1 parameters. - Additional tests have been introduced to allow 'jitter' to work with non-ISAAC frames. -----> eclipse-conica Development of the CONICA pipeline is going on. In its current state, the pipeline is only meant to be used by people working with the pipeline team. No public documentation has been released yet. -----> eclipse-python Build procedure --------------- The eclipse-python build procedure is now based on the distutils module which requires Python 2.0 or later, or if you are still running Python 1.5.2, you will need to download and install the distutils module (found on www.python.org). Unit tests ---------- The eclipse-python module now features unit tests, written using the unit testing environment provided by Python. This investment has already paid off by finding a number of very tricky bugs in the core libraries. The script previously written to test various eclipse-python capabilities will remain as an example of what can be done with this module. -----> eclipse-adonis No change. -----> eclipse-wfi No change. -----> eclipse-lua No change.
