GitLab

New Features

• Build system has been refactored to use CMake, a cross-platform build system (Windows and Linux)
• Building camera either standalone or using Lima as master project
• Better support for C++ developers (with CMake packages)
• Install.(sh|bat) to ease build and installation for CMake averse :-)
• Conda binary packages for processlib, LImA core and some cameras and pytango device server for Linux and Windows platforms
• Support for Python 3
• CI running on ESRF's Gitlab instance
• Documentation improvements and migrated to ReadTheDocs (https://lima1.readthedocs.io)
• Use semantic versionning
• New HDF5 layout, direct chunk and bitshuffle LZ4 / gzip compression support
• New BPM pytango plugin, Beam Position Monitor
• Simulator improvements (new prefetch and read from files modes)

New Camera Plugins

• ZWO camera plugin (thanks to Jens Krueger)
• SlsDetector (PSI Eiger) camera plugin (thanks to Alejandro Homs)
• FLI (Finger Lake Instrument) camera plugin (thanks to Laurent Claustre)
• Lambda (Quantum) camera plugin (thanks to Teresa Nunez)

Bug fixes

• Fix issues when allocating more HW buffers

New Features

• Refactor MemBuffer and Allocators (see MmapAllocator and NumaAllocator for instance).
• Add a NUMA variant of the SoftBufferCtrlObj instead of breaking its API with the LIMA_USE_NUMA macro.

Added missing CBF format support

The conda debug feature is now implemented as follow:

• LIMA_ENABLE_DEBUG (log) is always ON in the conda package and is ON by default in CMake
• DCMAKE_BUILD_TYPE=Debug with the debug feature
• DCMAKE_BUILD_TYPE=RelWithDebinfo without the debug feature

Dear Lima users,

We are pleased to announce the release of Lima v1.9

New features

• More conda packages for cameras are now supported:

  andor3, andor, basler, dexela, eiger, frelon, frelon, imxpad, maxipix, marccd, merlin, mythen3, pco, pilatus, pixirad, pointgrey, prosilica, simulator, slsdetector, ueye, v4l2, xh

• Refactoring and optimization of the software buffer classes

• Support added for Numa (non-uniform memory access) memory management

Bug Fixes

• CBF saving format now fits with miniCBF spec for Pilatus detectors
• Video: fixed issue when taking 8/16-bit images and then changing to Accumulation

New cameras

• PCO usb
• Frelon 16
• Zwo

Updated third-party tools and dependencies

• SIP >= 4.19.8
• HDF5 >= 1.10.4
• PyTango >= 9.2.5 (from tango-controls channel)

For developers:

• PyTango camera plugin documentation moved to the camera repo

• Enable log (DebParam) is back in release package

• Added a 'debug' meta-package to install conda package compiled with debugging (-g) option

Bug fixes

• check if hdf5 attribute exists before creating it
• Resolve "saving statistic missed"
• Flush statistic log file
• Use more explicit variable name in CtControl::newImageSaved

New features

• IntTrigMult: fix check of extra calls to CtControl::startAcq()
• Protect if detector is Ready but has not injected yet the last image into Lima
• HDF5: NXmeasurement does not exist, use NXcollection instead

Bug fixes

• remove (gcc) compiler warnings
• memory leak in ImageZCompression (HDF5GZ)
• CtSaving: fix thread synchronization issues
• CtBuffer: wait for processing to finish before releasing all mapped buffers
• CtSaving_Compression: refactoring of the ZBufferHelper class

Camera news

• Eiger (v1.9.4): Dectris Eiger camera submodule now support setting for http and stream port.

New features

• HDF5 container:
  • new attributes "file_name" and "file_time" to keep track of the original file path and creation date.
  • adjust the image dataset size to the number of acquired frames
  • in manual saving, keep a contiguous frame dataset
  • avoid Tango dead-lock timeout due to lengthy memory allocations

Bug fixes

• fix cmake find_package_handle_standard_args warning

• fix conversion compiler warning when calling import_array macro.

• HDF5 container:

  • Fix parallel saving:
    • Refactor SaveContainerHdf5::_File:
    • Add debug information when writing HDF5 Dataset chunk fails
    • Remove unused variables
    • Use AutoPtr for dynamically-allocated objects
    • Simplify initialization at _open
  • fixed bug with number of frames for last file.
  • adjust the image dataset to the real number of acquired frames

• Fix bug in CtControl::unregisterImageStatusCallback and improve code:

  • Allow unregisterImageStatusCallback if acq is not Ready
    • Do not throw exception: it is called from cb destructor
    • Status can be AcqFault, which is perfectly legal to unregister
  • Cosmetics
  • ThreadUtils: remove obsolete declarations in ReadWriteLock
