[QUOTE="deeptho, post: 1146242, member: 215446"] I have just released neumodvb-1.3. Lots of internal changes. Note that the database will be upgraded. That means you cannot switch back to older versions, but as always, neumodvb will create a backup prior to conversion. For instance /mnt/neumo/db/chdb.mdb will be copied to /mnt/neumo/db/chdb.mdb.20230423_22:19:43/ And likewise for devdb, statdb, epgdb, recdb. You can just replace the new with the old version: rm -fr /mnt/neumo/db/chdb.mdb cp -a /mnt/neumo/db/chdb.mdb.20230423_22:19:43 /mnt/neumo/db/chdb.mdb Satesco has already tested the new version. Here are the changes: [LIST] [*]Improved identification of muxes during scan, even when details such as network id and ts id change durign scan. This prevents never ending scans in more cases. [*]Updated documentation: mux list, status list. [*]Display correct mux data in more cases and display bad nit info in more cases (in red). [*]Show more mux information in service info on live screen. [*]Bug: wrong band reported for wideband lnb. [*]Also show total number of muxes during scan. [*]Bug: incorrect nid and tid shown in positioner dialog. [*]Perform pmt scanning also for t2mi streams. [*]Bug: isi scan times out too soon. [*]Bug: restricting service list to sat did not work properly. [*]Introduce new assert code, which allows continuing past assertion in debugger [*]New database schema for muxes and services: introduce mux_id as part of new primary for mux and remove extra_id. Add mux_id column in service list and mux list. Also, replace mux_desc with frequency and polarisation in services, allowing filtering of services based on frequency or polarisation. Add schema_version in database records and in data structures, to be able to detect major schema upgrades. [*]Code for handling major database upgrades from python and specifically converting to the database format needed for neumodvb-1.3. [*]Allow receiver initialization to be interrupted for major database upgrade and then for initialization to continue. [*]Avoid introducing streams with stream_id=-1 when multi stream exists but does not lock. [*]If mux cannot be locked, use NOLOCK as status instead of BAD. The latter means that the tuning parameters are invalid. [*]Add scan_lock_result. [*]Always preserve mux_key when consulting driver. [*]Never change stream_id even if driver reports the wrong one, but allow overriding stream_id with value from driver_mux when mux is template. [*]Properly handle case of stream ids changing during scan [*]Move some data from si.scan_state to si.tune_state, so that it is not cleared by si.reset(). [*]When looking up template mux with stream_id=-1, ignore stream_id in lookup to also find multi stream. [*]Simplify active_adapter_t::monitor() loop. [*]Bug: scan subscribers erased during si.reset. [*]Bug: passing local variables into tasks stored for other threads can lead to accessing invalid memory [*]Make by_scan_status key order by pol and frequency as secondary sort order, changing order in which muxes are scanned. [*]Avoid calling remove_fd with file descriptor <0. [*]Bug: Incorrect error message about fe and lnb not found. [*]Bug: Non Ku-Band subscriptions shown as None. [*]Avoid assertion in CmdBouquetAddService. [*]When selecting default network, take the one with the closest sat_pos rather than the closes usals_pos. [*]Workaround for possible kernel bug which causes epoll to report that eventfd is readable, whereas it is not. This causes a subsequent notifier.reset() to hang forever in read. [*]Bug: deserialize_field_safe: correctly skip variable size fields in old record [*]if peak_scan fails, then add the peak to the vector for future rescanning. [*]Handling of failed peak tuning improved. [*]Bug: data_start not correctly reset in some cases, using to incorrect no_data status. [*]Require FEC lock when scanning dvb muxes. [*]Bug: dereferencing std::optional without checking. [*]Trust modulation parameters from driver in more cases. [*]Bug: incorrect usage of make_key in screens sorting by predefined key. [*]Bug: passing auto variables into lambda leading to incorrect tune options during scan. [*]Deadlock due to active_si_stream_t destructor being called from receiver, causing access to functions which should only be used by tune thread [*]Bug deserialize_field_safe: correctly skip variable size fields in old record [/LIST] [/QUOTE]
