microdatasus 3.0.0

Downloads

• Reworks fetch_datasus() around an internal registry of supported systems and manifests built from the files actually published by DataSUS. Each relevant FTP directory is listed only once per call, avoiding redundant connections and URLs for files that do not exist.
• Selects a single file for each system, period, state, and file part. Definitive/current data take precedence over preliminary data, and current data take precedence over historical copies. Results retain deterministic period, state, and file-part order.
• Uses curl directly for directory listings and downloads, with per-operation timeouts and up to two retries for transient network failures. Downloads remain sequential, display transfer progress by default, and no longer modify the global options("timeout").
• Downloads through temporary partial files, validates file size and DBC contents, and reliably removes temporary files. With stop_on_error = FALSE, successfully read files are returned after a consolidated warning; with stop_on_error = TRUE, any failure aborts the operation.
• Applies vars before accumulating results and combines files only once, reducing repeated copies. When track_source = TRUE, the source column is retained even when vars is supplied, and an existing source column now produces a clear error.
• Strengthens validation of years, months, states, logical arguments, vars, and fractional timeout values. Monthly systems require months, annual systems ignore them with one warning, and "all" can no longer be combined with individual states.
• Replaces the former global 1996 lower-year restriction with historical limits specific to each information system. Existing public arguments, their order, and their defaults remain unchanged.
• Adds quiet at the end of the fetch_datasus() signature. Transfer progress and status messages, including each file name, are displayed by default; set quiet = TRUE to hide them. Warnings and errors remain visible.
• Uses immediate cli warning alerts when month arguments or state selections are ignored, including when quiet = TRUE.
• Standardizes download messages across microdata and auxiliary tables, with consistent status verbs, semantic cli formatting, indexed file progress, and one diagnostic item per failed directory or file.
• Hardens fetch_cadger() and fetch_sigtab() with shared timeout, retry, and temporary-file cleanup logic, and adds ZIP integrity and schema validation.

DBC support

• Removes the dependency on read.dbc and reads DBC files with vendored C code adapted from healthbR. Thanks to Sidney Bissoli for the open-source code.
• Adds read_dbc() for local DBC files, with optional preservation of the column types inferred from DBF metadata.
• Hardens read_dbc() by rejecting directories and empty or unreadable input files before decompression, validating missing, unknown-size, and empty decompression output, and wrapping DBF read failures in contextual errors with stable microdatasus_dbc_error subclasses.
• Expands local, CRAN-safe DBC tests for argument validation, type preservation, leading zeros, paths with spaces, repeat reads, temporary-file cleanup, and specific malformed header and compressed-stream errors.

Processing, documentation, and testing

• Adopts dplyr::recode_values() because dplyr::case_match() is deprecated.
• Expands and corrects the documentation for all public functions, including network behavior, actual return types, compatibility arguments, and links to the corresponding chapters of the book Sistemas de Informação em Saúde no Brasil.
• Replaces skipped download tests with deterministic simulated listings and transfers. The suite now covers supported systems, historical, current, and preliminary files, multipart data, complete argument validation, retries, timeouts, empty listings and manifests, cleanup, corrupt and empty files, partial success, vars, track_source, multiple states, and auxiliary-table schema validation. Local file:// fixtures exercise curl without network access; live DataSUS smoke tests remain opt-in and are always skipped on CRAN.
• Runs the active GitHub Actions R CMD check workflow for pushes and pull requests involving the dev branch as well as main and master.
• Requires R 4.1.0 or later.
