• refactored ctrGetQueryUrl and ctrOpenSearchPagesInBrowser
• harmonised error checking
• avoid some errors with external scripts
• refactored url / query mangling, added detailed testing
• refactored storing JSON into database (handle big files, reduce memory)
• improved dbFindIdsUniqueTrials (speed, memory, register coverage)
• factored out conversion to JSON
• accelerated EUCTR results and history download and storage
• external scripts now create multiple chunks of records
• use further identifier fields with dbFindIdsUniqueTrials

ctrdata 1.5.3

• include message how to handle server certificate issues, by propagating user settings for httr to curl operations
• ensure identical return structures when no new trials found
• dfTrials2Long: harmonise identifier level assignment, address cases where field occurs only once in input df
• dfMergeTwoVariablesRelevel: corrected and improved user info
• dfName2Value: remove duplicate rows, e.g. from duplicated criteria

ctrdata 1.5.2

• bugfix of EOL for converting EUCTR files
• remove LazyData from DESCRIPTION

ctrdata 1.5.1

• bugfix for non-matching euctr protocol and result ids: any trials from EUCTR for which results were downloaded with version 1.5.0 should be downloaded again (ctrLoadQueryIntoDb)
• dfTrials2Long refactored and accelerated
• API change: dfTrials2Long return value (identifier replaces main_id and sub_id)
• new option to save EUCTR results PDF files in user-specified directory

ctrdata 1.5.0

• return values of dbGetFieldsIntoDf are now mostly identical whether using src_mongo or src_sqlite, to best ensure portability of analysis code
• permit dots in queries / URLs
• improved handling of queryterm
• renamed ctrGetQueryUrlFromBrowser to ctrGetQueryUrl
• soft deprecated ctrGetQueryUrlFromBrowser
• ensure parallel retrievals from EUCTR
• speed up routines in dbGetFieldsIntoDf

• update curl parameters when accessing EUCTR

ctrdata 1.4.0

• new: easy access to variables with dfTrials2Long() + dfName2Value()
• improved dfMergeTwoVariablesRelevel() to maintain type of data
• revised and simplified vignettes
• deprecated: dfListExtractKey()
• refactored parts of euctr retrieval
• notify user when euctr register server does not permit compression and how long retrieval will take

ctrdata 1.3.2

changes from 1.3.0 onward

• quote system file paths
• fix error in CI tests
• workaround EUCTR certificate issue
• streamline ctrGetQueryUrlFromBrowser()
• better handling of complex fields
• include further tests for query string handling, checking more parameters and return values
• better clean-up after testing
• ctrLoadQueryIntoDb(querytorerun = ...) now looks for the date when the querytorerun was last run, to more often use euctr update options
• switching from travis to github action
• upped coverage of code tested
