feat(apply): support a separate restricted backup login - #251
Add an optional --backup-config FILE for apply --server-backup so the mandatory server backup can use a separate backup account while all tree writes remain on the existing writer client.

Walkthrough
The CLI adds optional credentials for server-backup requests. When configured, a restricted backup client handles backup operations, while the writer client continues to perform tree writes. Documentation, changelog entries, and tests cover the new configuration and flow.
Changes: Separate backup credentials
Layer / File(s)
Summary
Validate credentials and constrain backup requests apply/gwt_apply/cli.py, apply/tests/test_backup_config.py
The CLI validates backup credentials, rejects backup tokens and incomplete credential pairs, and restricts the separate client to backup and task requests. It rejects redirects, verifies the backup login reaches the writer’s tree, and closes the backup session. Tests cover these checks.
Integrate backup flow with apply and document settings apply/gwt_apply/cli.py, apply/tests/test_backup_config.py, docs/apply.md, docs/run.md, CHANGELOG.md
When server backup is enabled and backup credentials are present, the run uses a separate backup client. Otherwise, it retains the writer-client backup path. Tests cover backup success and failure cases; documentation and the changelog describe the settings and behavior.

Explanation
The title "feat(apply): support a separate restricted backup login" matches the main change. The PR adds a separate, restricted backup login for apply --server-backup, with tree writes kept on the writer client. The title names the scope (apply) and the feature. The PR objectives describe the same change. The title is concise and specific.
Full details: Description check
Explanation
The description follows the template sections (Change, Validation) but does not use the template headings. It has no Problem section stating what the user could not do. It has no Fix section naming the affected tool and docs page. It has no Shared rules section. It has no per-test guard list with red test output for each new test. The checklist item is missing. The description also points to a flag (--backup-config FILE) that the PR comments say was replaced by environment variables and the config file, so the description no longer matches the code. The docs and changelog changes are not mentioned.
Resolution
Rewrite the description with the repository template sections: Problem, Fix, Shared rules used, The guard each new test proves, and the checklist item. Under Problem, state that users could not use a separate restricted login for the mandatory server backup. Under Fix, name the apply CLI, the run config forwarding in gwt-run, and the docs pages changed (docs/apply.md, docs/run.md) and the CHANGELOG entry. Under Shared rules used, write "none" if no shared rule applies. Under The guard each new test proves, list each new test, the line it guards, and the failing output when that line is removed. Update the Change section to describe GWT_BACKUP_USERNAME and GWT_BACKUP_PASSWORD instead of --backup-config FILE, and state the rule that a token or a partial credential exits before login.

Explanation
Docstring coverage is 17.65% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 17 functions across 2 files. (3 skipped: 3 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Review of this PR. The problem is real: today --server-backup needs an owner or admin login, so the only way to get the gate is to run the whole write chain as owner. Keeping the writer an editor and using an owner login only for the backup is the right split, and the backup-only client, the tree check and the no-redirect session are worth keeping. We are pushing a few changes to this branch.
What we change, and why:
The backup login comes from the existing settings, not a second file.
), so the write chain could not use the feature without a second PR. We replace --backup-config with two keys read like every other setting: GWT_BACKUP_USERNAME and GWT_BACKUP_PASSWORD, in --config or the environment. URL and tree always come from the writer, so the URL/tree mismatch cases go away. The keys count only with --server-backup, so one --config still serves every gwt-run step.
No token for the backup login. On Gramps Web only owner and admin hold the backup permission, and a sync token drops it even for an owner. A token-only backup config (
raiseValueError("backup config needs a valid URL and its own username/password or token")
) always ended in a 403 telling the user they need an owner login. GWT_BACKUP_TOKEN, or only one of the two keys, now exits 2 with its own message, before the login and the lock.
turned every OSError/ValueError into "the private backup config could not be read", including a non-JSON server answer after the backup POST, when a backup may already be stored. With no file left there is nothing to catch there; the backup login's ApiError is reported with its own text (
returnf"the separate backup login failed (HTTP {exc.status}); nothing was applied"
printed "HTTP None" for a wrong tree and dropped "refused an HTTP redirect").
Docs say it is an owner login. The server would allow that account everything an owner can do; only our client limits it to /backups/ and /tasks/<id>. The doc text moves from under "Undo a run" (
), with the file. The writer's --config can hold credentials with write access and gets no such check, and it refuses a read-only secret mount owned by another user. If we want a permission rule, it belongs on --config for both logins, in its own change.
The two tests tied to the file (symlink, --backup-config without the gate) and the URL/tree mismatch mutant row.
What we leave as it is:
The no-redirect session and the route allow-list. They limit only our own code, and the editor login has the same redirect exposure, but they are small, tested, and the owner password is the one worth the extra care. Moving redirect refusal into Client for every login would be its own PR.
Each change has a test that fails on this PR's head, and the mutant rows cover the new checks.
…e it
gwt-run hands each gwt-apply step only --config and the environment, so a
separate --backup-config file never reached the write chain. The backup
login is now GWT_BACKUP_USERNAME and GWT_BACKUP_PASSWORD, read like every
other setting, on the writer's URL and tree, and only with --server-backup.
A sync token never holds the backup permission on Gramps Web, so
GWT_BACKUP_TOKEN, or half a login, exits 2 before the login and the lock.
Backup login errors keep their own text instead of one catch-all line.
The mode-0600 file check goes with the file.
The docs move into the --server-backup section and say plainly that the
backup account is an owner or admin; gwt-run's --config row and the
CHANGELOG name the keys.

…ant rows
The route allow-list had three parts no test caught: the anchored task
route, the GET/POST-only rule on /backups/ and the exact /backups/ path.
Changing any of them left the suite green, and so did pointing the backup
login at another URL. The rejected routes now include DELETE and PUT on
/backups/, a backup's own route and a /tasks/ path with "..", the fake
session checks every call goes to the writer's host, and each check has a
mutant row.
Merged as 5e2f0ea, thank you Marco. Splitting the owner login off the writer is the right call. We moved it onto GWT_BACKUP_* keys so gwt-run picks it up with no change, and kept your backup-only client, the redirect refusal and the tree check. It ships in 1.4.0.
Ships #251: gwt-apply --server-backup can make its backup with a separate owner or admin login, so the writer stays an editor. Change lists: None.
