New features

• lima_conda_build script: local Conda compilation with optimization for native architecture

Bug fixes

• #135: Fix unprotected member access in CtSaving::_getTaskList
• #131: InvalidValue exception, roi-out-of-limits when applying rotation with an image_roi already defined fix computation of the max_roi according to the current binning and rotation Add equality operators for Size and their missing python bindings for Point, Size and FrameDim Add test for ROI computation for every bin / flip / rot
• #130: continuous acquisition and hdf5 saving broken fix deadlock resulting in saving task stall and consequently AcqStatus being AcqRunning indefinitely fix _calcAcqStatus when acq_nb_frames == 0
• #120: stopAcq() destroying non empty allocator Do not destroy default Allocator until it's empty

Camera updates

• Maxipix 1.9.1: fixed latency_time calculation when in hardware trigger mode

• Pilatus 1.9.1:

  • Bug Fix: IntTrigMult trigger mode, mode to software trig each image exposing, has been repaired, and can be use now to have faster software acquisition sequence
  • New Features: Tango: new properties to run the server on a slave computer, not only on the DCU computer:
    • tmpfs_path. default = /lima_data
    • host_name, default = localhost
    • host_port, default = 41234
    • config_path, default = /home/det/p2_det/config/cam_data/camera.def

• Simulator 1.9.2:

  • Fix EDF Parser (allow smaller header block of 512Kib)
  • Fix Prefetch mode (segfault and/or black images with some use cases)

New cameras

• Arinax: The OAV B-ZOOM is an On-Axis Video-microscope with a hybrid zoom system used for parallax free observation of micrometer sized crystals. It is optimized for MX crystallography beamlines and high throughput stations in Synchrotrons.
• QHYccd: high-performance scientific grade CMOS and CCD cameras

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

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.

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

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

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

Added missing CBF format support
