Validate Git-Storage Consistency — datom

Checks that git metadata matches S3 storage for all tables and repo-level files. Reports mismatches as a structured result.

Usage

datom_validate(conn, fix = FALSE)

Arguments

conn: A datom_conn object from datom_get_conn().
fix: If TRUE, attempts to fix inconsistencies by syncing data-side metadata (manifest + per-table metadata) to storage.

Value

A list with:

valid: Logical — TRUE if everything is consistent.
repo_files: Data frame of repo-level file checks.
tables: Data frame of per-table checks.
fixed: Logical — TRUE if fix = TRUE was applied.

Examples

# Offline, self-contained: a bare git repo stands in for GitHub and a
# local directory for object storage.
if (requireNamespace("git2r", quietly = TRUE)) {
  tmp <- tempfile("datom-example-")
  remote <- file.path(tmp, "remote.git")
  dir.create(remote, recursive = TRUE)
  git2r::init(remote, bare = TRUE)

  store <- datom_store(
    data = datom_store_local(file.path(tmp, "storage")),
    github_pat = "example-token", # role selector; a local remote needs none
    data_repo_url = remote,
    validate = FALSE
  )
  datom_init_repo(file.path(tmp, "repo"), "example_project", store)
  conn <- datom_get_conn(file.path(tmp, "repo"), store)

  datom_write(conn, data = datom_example_data("dm"), name = "dm")
  datom_validate(conn)

  unlink(tmp, recursive = TRUE)
}
