jcoffey-dev is traveling from Thursday 1 October through Sunday 4 October. Issues and pull requests are welcome, and will get an answer after that. Thanks for your patience.
The flag switched certificate checks off for every connection in the run.
That included the Microsoft sign-in endpoints, so a user passing it for a
self-signed source also sent refresh tokens, device codes and EWS client
secrets over unverified TLS. It also covered the export target, and any host
a server redirected to or named for its API, uploads or downloads.
It now applies only where the user pointed it: the host of --url, for the
source of an import or the target of an export. For an Exchange import with
no --url, it covers the mailbox's own domain, where on-premises Autodiscover
looks, and then only the EWS endpoint Autodiscover finds. The Microsoft and
Google sign-in and cloud hosts are always verified, with or without the flag.
Each HTTP client keeps a verifying agent and, only when the flag applies, a
second one that accepts invalid certificates, and picks per request by host.
The sign-in modules no longer take the flag at all. Autodiscover v2, which is
Microsoft's own service, is always verified.
No ureq agent set a timeout, and ureq sets none by default, so a connection
dropped silently mid-transfer (a NAT or load-balancer idle drop) hung a JMAP,
DAV, EWS or Graph run, or an export, with no error, and the retry logic never
got a chance to run. IMAP and ManageSieve already had read timeouts.
Every agent now takes its settings from a new net module: 30s to connect,
60s to send the request headers, 5 minutes for the server's first byte, and
30 minutes for a whole response body, which ureq counts as one budget for the
body rather than per read: enough for the 512 MiB limit at about 300 KB/s.
A JMAP upload's send budget grows with its size, from a 2 minute floor at an
assumed 64 KiB/s worst case.
A timeout is a transport error, and every client already retries those, so a
stalled transfer is now abandoned and retried. Tests pin that down for each
client. The TLS setup the seven agents repeated moves to one helper.
The crate, binary, library path and every name the tool writes or reads
become inbuxa-migrate: the CLI name and about text, the HTTP user agent,
the credential variables (INBUXA_MIGRATE_PASSWORD, _TOKEN,
_EWS_CLIENT_SECRET and _GRAPH_TOKEN, with no fallback to the old names),
thread names, synthesized UIDs and calendar addresses
(urn:x-inbuxa-migrate:attendee:), and the Maildir file suffix used by the
export script. This is a new tool, so archives written by Vandelay are not
read back.
The version moves to the date scheme the release tags use (2026.9.30), and
the package metadata points at the inbuxa-migrate repository. The cargo-dist
and MSI metadata goes with the release tooling it served.
