27 * Logging: add more specific information to contextualize the logs. |
| 5166 | 28 For a DICOM Transfer, that would be nice to include the modality in the context + a study identifier or a job id. |
| 4927 | 29 * (1) Accept extra DICOM tags dictionaries in the DCMTK format '.dic' (easier to use than declare |
| 4885 | 30 them in the Orthanc configuration file). Even the standard dictionaries could be |
| 31 overriden by these custom dictionaries. | |
| 5013 | 32 * Add configurations to enable/disable warnings: |
| 33 - Modifying an instance while keeping its original SOPInstanceUID: This should be avoided! | |
| 5034 | 34 - Modifying a study while keeping its original StudyInstanceUID: This should be avoided! |
| 5391 | 35 * Store the job registry in a dedicatd table in DB ? |
| 36 https://discourse.orthanc-server.org/t/performance-issue-when-adding-a-lot-of-jobs-in-the-queue/3915/2 | |
| 37 Note: that might also be the right time to have a central jobs registry when working | |
| 38 with multiple Orthanc instances on the same DB. | |
| 5727 | 39 Note: the json serialization of a job "content" can be very large -> compress it before saving it to DB ? |
| 5400 | 40 * Right now, some Stable events never occurs (e.g. when Orthanc is restarted before the event is triggered). |
| 41 Since these events are used to e.g. generate dicom-web cache (or update it !), we should try | |
| 42 to make sure these events always happen. | |
| 43 - Generate the events when setting IsStable=true when starting an Orthanc (ok for SQLite) ? | |
| 44 - Also consider the use case of an Orthanc cluster that is being scaled-down just after one Orthanc instance | |
| 45 has received a few instances -> we can not only check for missing stable events at startup since no Orthanc will start. | |
| 46 We would need to maintain the list of "unstable" resources in DB instead of memory only. | |
| 47 * In prometheus metrics, implement Histograms or Exponential Histograms to measure durations. Right now, we only provide | |
| 48 "average" durations that are not very relevant | |
| 49 (https://opentelemetry.io/docs/specs/otel/metrics/data-model/#histogram) | |
| 50 - for job durations (+ have one histogram for each job) | |
| 51 - for HTTP request handling | |
| 52 - ... | |
| 5409 | 53 * Investigate if one could fix KeepAlive race conditions: |
| 54 https://discourse.orthanc-server.org/t/socket-hangup-with-rest-api/4023/3 | |
| 5557 | 55 * The DICOM file cache shall keep a MD5 of the cached file and compare it with MD5 |
| 56 from the DB. That would allow 2 orthancs in a swarm to realize when the other | |
| 57 Orthanc has updated the file: | |

232 - RequestAttributesSequence (sequence that must be included in all DicomWeb QIDO-RS for series) |
| 4467 | 233 |
| 4986 | 234 * Long-shot & not sure it is even feasible at all: try to reduce memory usage by implementing streaming |
| 235 when receiving DICOM instances from the Rest API or from DICOM and store files directly to disk as they | |
| 236 are received. Note that this would likely require rewriting large parts of Orthanc. Note sure that | |
| 237 would be compatible with Transcoding. | |
| 238 Use case: receiving 10 1GB instances in parallel can consume up to 20 GB | |
| 239 Alternative option 1: write an "external application/plugin" that would take care of these receptions, write the | |
| 5096 | 240 file at the right place and send a signal to Orthanc to "adopt" the file. |
| 4986 | 241 Alternative option 2: declare a memory resource (X GB) that is available for reception. Every time |
| 5096 | 242 Orthanc starts receiving a file, it reserves the memory or twice the memory (through a Semaphore) |
| 243 if no memory is available, it waits and possibly timeouts returning a 503 or DIMSE A700 (out of resources). | |
| 244 This would at least protect from "out of memory" crashes. | |
| 245 Alternative option 3: Configure DCMTK to "stream" DICOM files on a temporary file on disk. Pass the file handle | |
| 246 to Orthanc and/or the Storage plugin (instead of passing a memory buffer) -> the object-storage plugin could | |
| 247 "stream" the file to the storage. The HTTP server could also "stream" its response from file handles. | |
| 248 Transcoding should be "file based" too. | |
| 5404 | 249 * To investigate: usage of mapped_file (not only in the indexer plugin): |

| 4926 | 368 * Add more complex testing scenarios like data-migration, change of |
| 369 configuration files, multiple orthanc interacting togethers with various | |
| 370 config. This should probably look like the python toolbox tests ... | |
| 5304 | 371 - add a test to validate Modalities and Peers stored in DB are not lost |
| 372 while upgrading from one version to the other (Sylvain) | |
| 5349 | 373 * On Ubuntu 20.04, accesses to unitialized memory are sometimes |
| 374 reported in libgjpeg by valgrind, if running the following command | |
| 375 (this is probably unrelated to Orthanc): | |
| 376 $ ./Start.sh --force Orthanc.test_bitbucket_issue_141 Orthanc.test_create_pdf Orthanc.test_decode_brainix_as_jpeg | |
