Allow LoTW batch updates to reference QSOs by COL_PRIMARY_KEY for reliable matching. Controller: include 'primary_key' in batch update payloads. Model: collect numeric primary keys, expand WHERE to include COL_PRIMARY_KEY IN (...) alongside the existing datetime/call/band/station match, add early exit/log when no usable keys provided, and build an id-based lookup (qso_map_by_id) to prefer primary-key matches while remaining backward-compatible with the composite key lookup. This reduces ambiguous matches and improves update accuracy.
Add mappings for QMR-KWT-2 -> QMR-KWT-2_(RS95S) and Lobachevsky -> Lobachevsky_(RS83S), and introduce conditional APRS name mapping for BOTAN (when COL_MODE == 'PKT') and SONATE-2 (when COL_MODE == 'PKT'). These changes extend satellite name normalization in application/models/Logbook_model.php to handle these satellites and modes.
In Logbook_model.php, replace select('DISTINCT user_id') with $this->db->distinct(); $this->db->select('user_id') to use CI's distinct API and produce correct SQL. Also correct the where clause to use station_logbooks_relationship.station_location_id instead of station_id so shared-access users are filtered by the proper station location.
Add per-user/logbook file caching for dashboard statistics (15min TTL) and update Dashboard controller to use cached qso, countries, VUCC and QSL queries. Introduce clear_dashboard_cache() in Logbook_model and call it on QSO create/update/delete to invalidate affected users' cache entries. Add migration (249) to create composite indexes (idx_dxcc_stats, idx_vucc_gridsquare, idx_vucc_grids) to improve dashboard query performance, and bump migration_version to 249. Also include generated cache files under application/cache for current stats.
Bump migration version to 247 and add a migration that creates performance indexes for LoTW workflows (idx_lotw_qslrdate, idx_lotw_qsos_to_upload, idx_lotw_confirmation_match) to speed common queries. Refactor Lotw controller to collect records in memory, build rows for rendering, and perform a single batch confirmation update via a new Logbook_model::lotw_update_batch() method instead of many individual updates. Implement lotw_update_batch() to look up matching QSOs, perform update_batch() calls, and separately update gridsquares/distances using the Qra library. Simplify LotwCert::toggle_archive_certificate() to toggle archived state with a single UPDATE and return the resulting status.
Improve query performance and memory usage by adding a migration to create several indexes and converting various upload/reporting flows to batched processing. Changes include:
- Add migration 245 to create indexes: idx_mode, idx_sat_name, idx_continent, idx_qsl_stats (composite), idx_hrdlog_upload, idx_qrz_upload to speed common queries.
- Bump migration version to 245 in config.
- Hrdlog and Qrz controllers: switch to fetching QSOs in LIMIT/OFFSET batches, process updates in chunks, add logging for batch progress, and use break 2 to stop outer loops on invalid API keys to avoid continuing work.
- Logbook_model:
- get_hrdlog_qsos and get_qrz_qsos now accept limit/offset and use ORDER BY/LIMIT/OFFSET for batching.
- Replaced a subquery with a JOIN for grid-based filtering to improve performance.
- get_modes rewritten to use query builder (distinct/select/order_by).
- Bulk DXCC updates use update_batch instead of per-row queries.
- calls_without_station_id limited to 500 results to avoid UI hangs.
Overall goal: prevent memory exhaustion with large datasets and improve database query performance.
Replace repeated LEFT OUTER JOIN (SELECT callsign, MAX(lastupload) ...) derived-table joins with simpler LEFT JOIN lotw_users lotw across Distances_model, Logbook_model, Logbookadvanced_model, and Worked_all_britain_model. Also remove an unnecessary DISTINCT/inner station_profile join from an optimized Logbook_model subquery. These changes simplify SQL emitted by the CI query builder, improve compatibility and readability, and may improve performance; note that using direct joins can change which lastupload row is returned if multiple lotw_users rows exist for a callsign.
Introduced a useragent_helper with a function to generate a compliant User-Agent string for Cloudlog, and updated QRZ API calls in Qrz controller and Logbook_model to use this helper. This ensures consistent and QRZ-compliant User-Agent headers for all outgoing requests.
Corrects the logic for assigning DXCC ID when the country is set and dxcc_id is 0 by fetching the DXCC ID from the callsign lookup. This ensures the correct DXCC ID is used in these cases.
Introduces the Personal Propagation Advisor, allowing users to analyze their own QSO data to determine the best times, bands, and modes for working specific DXCC entities. Adds a new controller, model methods, view, JavaScript, and language strings in multiple languages. Updates navigation and footer to support the new feature.
Updated the call to getAdifLine in Logbook_model to include a second parameter set to true. This may enable additional functionality or formatting in the ADIF line generation for Clublog integration.
Replaced checks for QSO accessibility with stricter write permission checks across controllers and models. Added a new check_qso_is_writable method to Logbook_model to ensure only authorized users can modify or delete QSOs, including shared logbook scenarios. Updated QSO, Qsl_model, and Sstv_model to use the new permission logic for all write operations.
Enhanced the QSO access logic to allow access if the QSO belongs to the user or is part of a user's active logbook, including shared permissions. Added a guard in the controller to prevent accessing missing or inaccessible QSOs, redirecting with a notice if access is denied.
Replaces direct joins to lotw_users with subqueries that select the latest (MAX) lastupload per callsign in Distances_model, Logbook_model, and Logbookadvanced_model. This ensures only the most recent LoTW upload per callsign is joined, improving data accuracy and preventing duplicate join results.
Replaces direct join with lotw_users table by joining a subquery that selects the latest lastupload per callsign. This improves performance and ensures only the most recent LOTW upload date is included for each callsign.
Updated the csadditions regular expression in Logbook_model.php and Dxcc.php to include 'B' as a valid suffix for DXCC lookup and call sign parsing. This change ensures callsigns with '/B' are properly recognized in DXCC-related functions.
Updated the SQL statement in Logbook_model to use utf8mb4_general_ci collation instead of utf8mb4_unicode_ci for the MEMORY table QSO_LOOKUP. This may improve performance for certain lookup operations.
In Logbook_model.php, LoTW and eQSL sent status are reset to 'N' when editing a QSO that was previously sent, ensuring re-upload to these services. In common.js, a handler updates DXCC, location, and state fields when the callsign is changed in the QSO edit modal.
Replaced raw SQL LIKE conditions with CodeIgniter's query builder 'like' and 'or_like' methods for VUCC search cases. This improves code readability and helps prevent SQL injection.
Enhanced input validation for gridsquare and band parameters in Awards controller to prevent invalid data and potential abuse. Updated Logbook_model to use parameterized queries and early return for empty logbook relationships, improving security and reliability of VUCC QSO details retrieval.
Improves performance of QRZ QSO upload by batching database updates in the controller and model, reducing the number of individual update queries. Adds a new migration to create indexes supporting QRZ upload/download operations. Refactors QRZ download batch processing to use temporary tables and efficient JOINs for large batch updates, further enhancing speed and scalability.
Enforces that Clublog usernames are valid email addresses throughout the application, reflecting Clublog's policy change to no longer accept callsigns as usernames. Updates validation in controllers, models, and views, adds a migration to clear non-email usernames, and updates language files in multiple languages to clarify the requirement.
Refactored variable names for clarity and added detailed logging for Clublog realtime upload results. Now resets user credentials if a 403 error is returned by the Clublog API, and includes HTTP status code in the response for better error handling.
Replaces individual QSO update queries with a new mark_lotw_sent_batch() method in Logbook_model for improved performance during LoTW uploads. Updates Lotw controller to use batch updates within a transaction, reducing database load and increasing efficiency for large QSO uploads.
Added extensive debug output and error handling to LoTW upload and download processes for easier troubleshooting. Refactored SQL queries in Logbook_model and Logbookadvanced_model to simplify and optimize data retrieval, replacing subqueries with more direct joins and query builder usage. Removed migration 217_add_performance_indexes.php.
Refactored SQL queries in Logbook_model and Logbookadvanced_model to use subqueries for filtering and pagination, improving performance and accuracy. Updated joins and selected fields for consistency and to avoid duplicate results, especially when limiting and ordering large datasets.
Enhanced the DXCC lookup in Logbook_model to include latitude and longitude in the returned array. Updated API controller to utilize these new fields when returning recent QSOs and callsign lookups, providing more detailed location data in API responses.
The recent_qsos API endpoint now validates and sanitizes the $limit parameter, enforcing a default of 10, a minimum of 1, and a maximum of 50. Additionally, get_last_qsos in Logbook_model ensures $num is always an integer to prevent SQL injection.
Changed the SQL query in get_last_qsos to use LEFT JOIN for station_profile instead of JOIN. This ensures that QSOs are returned even if there is no matching station_profile, improving data completeness.
Removed the limit parameter validation and sanitization from Api.php, delegating limit handling elsewhere. Changed the SQL query in Logbook_model.php to use LEFT JOIN for station_profile, ensuring all logbook records are included even if no matching station_profile exists.
Standardized code formatting and indentation throughout Logbook_model.php for improved readability and maintainability. No functional changes were made; only whitespace, comment alignment, and consistent brace placement were updated.
Refines how DXCC ID is set based on country and input values, ensuring correct assignment when country is provided and dxcc_id is zero. This helps prevent incorrect DXCC ID values during logbook entry creation.
Updated country name formatting to support both array and object types for the entity returned by get_entity. This ensures compatibility with different data structures and prevents errors when accessing the country name.
Added 'callsign' property to plot data in Logbook_model and updated custom_date.php to use only the 'callsign' for map labels. Simplified and removed aggressive CSS targeting for tooltip classes, ensuring consistent font size and cleaner label rendering.
Introduces a button and supporting logic to toggle callsign labels on the map using Leaflet DivIcons. Also updates the Logbook model to include gridsquare in plot data for potential label use and enhances CSS for callsign label styling.
Replaced multiple individual queries in Dashboard controller with consolidated methods for setup counts and country statistics. Added getAllSetupCounts to Setup_model and get_countries_statistics_consolidated to Logbook_model to improve performance and reduce database load.
Optimized SQL query by pre-calculating today's date in PHP and improved result handling by returning a consistent array with integer values. Simplified logic for default values and removed unnecessary variable assignments for better readability and maintainability.
Replaced multiple individual queries for QSO statistics in Dashboard controller with a single consolidated query in Logbook_model. This improves performance by reducing database calls when fetching today's, total, monthly, and yearly QSO counts.
Updated the query to use or_like on COL_VUCC_GRIDS instead of applying SUBSTRING, ensuring proper matching of the grid prefix. This resolves issues with grid searches not returning expected results.
