repoman.checker

Availability checker: tests repos against a target Ubuntu codename.

Runs entirely in a background thread. Never touches GTK widgets. Uses Launchpad API for PPAs and HTTP HEAD for all other repos. A single network failure sets a global flag that suppresses further attempts, so one DNS outage does not cause a storm of error toasts.

reset_network_state()

Reset the network failure flag — useful between wizard runs.

Return type:

None

get_network_error()

Return the last network error message, or empty string if none.

Return type:

str

class Checker

Bases: object

Checks repo availability for a given Ubuntu codename. Run in a background thread — must not touch GTK widgets.

On the first network error (timeout, DNS failure, HTTP error), the checker marks the global network-failed flag so the UI can surface a single alert and all subsequent checks return UNKNOWN immediately.

check(repo, codename)

Check whether repo has packages published for codename.

Suite-agnostic repos always return SUITE_AGNOSTIC without a network call. If the global network-failure flag is set from a previous call, returns UNKNOWN immediately to avoid a cascade of timeouts.

Parameters:

• repo (Repository) – The repository to check.

• codename (str) – Ubuntu codename to check against, e.g. "noble".

Returns:

Availability status for this repo/codename pair.

Return type:

AvailabilityStatus
