pubsub: breaking changes to timing option names and units - #742
Four breaking changes to the timing client options for 4.0.0, plus a fix for a timedelta ttl, one commit each. Every commit has an entry in UPDATING.md, updates test/uts/deviations.md where its counts change, and passes ruff, test/unit and test/uts on its own.
The timing options came in two units. The three HTTP options were seconds and the five others were milliseconds, with nothing in the names to tell them apart, while TO3l counts all of them in milliseconds. The decision for 4.0 is that all eight take seconds, as an int or a float, and each is renamed with a _seconds suffix. Seconds is what a Python caller expects. The rename is what makes the migration loud: Options passes unknown keyword arguments on to AuthOptions, so an old name raises TypeError at construction. A carried-over disconnected_retry_timeout=15000 fails at once, rather than silently meaning a retry about four hours away.

Take the five millisecond options in seconds, as *_seconds. The defaults are now 10, 15, 30, 15 and 600, and they read back from Options under the new names. The clock API still counts milliseconds. Options converts each option in one place, seconds_to_ms, which sits behind a private _<option>_ms property. The connection manager, the channel timers, the transport's idle timeout and the HTTP fallback cache all read those properties. seconds_to_ms rounds to the microsecond rather than truncating, so 0.0015 is 1.5 ms and 0.1 is exactly 100 ms. The ping() timeout runs on the event loop's clock, so it reads the seconds directly. Every UTS test that sets one of these options now passes the spec's value divided by 1000. Migration: rename the option and divide the value by 1000, or pass timedelta(...).total_seconds().
Rename the three HTTP options to *_seconds. Only the names change; the unit and the defaults stay the same. The httpx Timeout and the RSC15 retry budget read the new names, and so do the Http properties. rest/proxy/RSC15l2/timeout-triggers-fallback-0 was gated because it passed the spec's httpRequestTimeout: 3000 straight through as 3000 seconds. It now passes http_request_timeout_seconds=3 and is un-gated: against the proxy it times out at about 3 s and succeeds on the fallback. Its Failing Tests entry and candidate issue I.3 are removed. Migration: rename the option and keep the value.
Name the replacement when an old option name is passed. It is still a TypeError, so nothing that raised before stops raising. For a millisecond option the message converts the value passed, for example TypeError: `disconnected_retry_timeout` was renamed to `disconnected_retry_timeout_seconds` in 4.0 and is now in seconds (15000 ms → 15). For an HTTP option it says the unit is unchanged. A missing credential is still reported first, as 40106. Migration: none beyond the renames; the message tells you the fix.
Validate the eight options at construction. Each must be a finite, non-negative int or float. A bool, a string, a negative value, NaN, an infinity or a timedelta raises InvalidArgumentException with 400/40000. That is pubsub: breaking changes to exceptions #737's subclass, and also a ValueError. The code follows push.admin.publish, which uses 40000 for invalid non-credential arguments; 40106 is for credentials. A timedelta used to be accepted and then raised inside the timer task, so the retry never fired. Its error now says to pass total_seconds(). The three HTTP setters validate too. None still means the default, and zero is accepted. There are no magnitude warnings. Migration: fix any invalid value; a timedelta needs .total_seconds().
Send a timedelta ttl to the millisecond. Token ttl stays int ms, but a ttl given as a timedelta was converted through total_seconds() and int(), which truncates. As a result, 1,482 of the whole-millisecond values from 0 to 200,000 were sent one short: timedelta(milliseconds=1001) was requested as 1000. Whole seconds were unaffected. Both conversions, in create_token_request and in the params sent to an auth_url, now go through ttl_ms, which divides by timedelta(milliseconds=1) and so stays in integer arithmetic. A ttl given as a number is sent as before. Migration: none.
Scoped down or skipped
Wire values keep their spec names and stay int ms: token ttl (TokenParams/TokenRequest), ConnectionDetails (max_idle_interval, connection_state_ttl), Auth.time_offset, all timestamps, and the round trip ping() returns. They are protocol values rather than client configuration.
The internal millisecond values in Defaults are unchanged:connect_timeout, disconnect_timeout, suspended_timeout, comet_* and connection_state_ttl. None of them is the default of one of the eight options. Only the eight defaults moved to *_seconds names.
No other public duration option was found.AuthOptions has none (query_time is a bool), and max_message_size and http_max_retry_count are not durations.
The rest of http_request_timeout does not bound a REST request #709 is untouched: the value still bounds one socket read rather than the whole request, and the retry budget is still not checked during an attempt. This PR only settles the unit question on that line.
Tests
test/uts, measured at the parent and at each commit. Every tier was run separately under caffeinate with a watchdog, and every run completed on the first attempt:
parent v4-channels (72d00f8)

commits 2–5 (head)

1585 passed, 171 skipped

The outcome of every test was diffed against the parent's, in both modes. Commit 1 matches the parent test for test. From commit 2 on, the only difference is that test_rsc15l2_timeout_triggers_fallback passes instead of being skipped or failing. The deviations.md figures were re-measured at each commit from the junit reports and the # UTS: comments, not adjusted from the parent's. They change only at commit 2:
Test IDs: 1304 pass (1313 tests, 1438 cases) and 141 are gated (143 cases).
By side: REST 63/64 gated, realtime 78/79.
SDK non-compliance: 130 Test IDs (132 cases), from 54 root causes (17 REST, 37 realtime), 55 in all.
New tests in test/unit/options_test.py:
defaults and given values read back, in seconds and through the _ms properties
seconds_to_ms's exact conversion
the rename TypeError messages, through Options and both factories
every invalid type and value for every option, and the HTTP setters
New tests in test/unit/token_ttl_test.py check the ttl conversion for every millisecond up to 200 seconds, and at both call sites. Commit 5 changes no UTS outcome; it was run in full in both modes, without the per-tier watchdog.
deviations.md records the eight options as an intentional naming-and-unit deviation, in a new Timing options are seconds, and named for it table under Adapted Tests. The RTC7 and TO3l4/TO3l5 rows now point there instead of at an open bug.
The legacy test/ably suite was not run. These files were edited by hand to use the new names and units and want a CI run:
test/ably/testapp.py
test/ably/realtime/realtimeauth_test.py
test/ably/realtime/realtimechannel_test.py
test/ably/realtime/realtimeconnection_test.py
test/ably/http/httphttp_test.py
test/ably/http/httpinit_test.py
test/ably/http/httprequest_test.py
CLAUDE.md's Time section and the uts-to-python skill now say that the options are seconds and the clock is ms.
Timeout options now use _seconds names and accept values in seconds instead of milliseconds. Existing option names raise TypeError; update configurations to use the new names and units.
New Features
Timing options are validated when creating a client. Values must be finite, non-negative numbers; zero is allowed.
HTTP request timeouts also cover request-body writes and connection-pool waits, and can trigger a fallback-host retry when exceeded.
TO3l1, TO3l2, TO3l7, TO3l10 and TO3l11 count disconnectedRetryTimeout,
suspendedRetryTimeout, channelRetryTimeout, fallbackRetryTimeout and
realtimeRequestTimeout in milliseconds, and ably-python took
realtime_request_timeout, disconnected_retry_timeout,
suspended_retry_timeout, channel_retry_timeout and fallback_retry_timeout
in milliseconds too. Its three HTTP timing options took seconds, so a
client's options came in two units with nothing in their names to say
which.
The five options now take seconds, as an int or a float, and are renamed
realtime_request_timeout_seconds, disconnected_retry_timeout_seconds,
suspended_retry_timeout_seconds, channel_retry_timeout_seconds and
fallback_retry_timeout_seconds, defaulting to 10, 15, 30, 15 and 600.
They read back from Options under the new names. The clock still counts
milliseconds, so Options converts each one in a single place,
seconds_to_ms, behind a private _<option>_ms property that the
connection manager, the channel, the transport and the HTTP fallback
cache schedule with. It rounds to the microsecond rather than
truncating, so 0.0015 is 1.5 ms and 0.1 is exactly 100. The ping timeout,
which runs on the event loop's clock, reads the seconds directly. The
Defaults move to seconds under the new names; the internal millisecond
values in Defaults are unchanged.
Every UTS test that sets one of these options divides the
specification's value by 1000, and the RTC7 defaults test reads the
seconds back. test/uts/deviations.md records the renamed options as an
intentional naming-and-unit deviation under Adapted Tests. No gated test
changes, so its counts do not.
This is a breaking change: passing an old name raises TypeError, so a
3.x value fails at construction rather than meaning a timeout a thousand
times too long. Callers should rename the option and divide its value by
1000, as UPDATING.md shows. Token ttl, ConnectionDetails,
Auth.time_offset, timestamps and the result of ping() stay milliseconds.

TO3l3, TO3l4 and TO3l6 count httpOpenTimeout, httpRequestTimeout and
httpMaxRetryDuration in milliseconds. ably-python's http_open_timeout,
http_request_timeout and http_max_retry_duration have always been
seconds, with nothing in their names to say so. A caller following the
specification's units passed http_request_timeout=3000 and got a deadline
of fifty minutes: rest/proxy/RSC15l2/timeout-triggers-fallback-0, which
does exactly that, sat out the proxy's 20-second delay on the primary
host and never fell back, so it was gated as an open bug.
The three options are renamed http_open_timeout_seconds,
http_request_timeout_seconds and http_max_retry_duration_seconds, with
their units and defaults of 4, 10 and 15 unchanged, to match the
realtime timing options. They read back from Options, and from the Http
properties, under the new names, and still reach the httpx Timeout and
the RSC15 retry budget as seconds.
The RSC15l2 test now passes httpRequestTimeout: 3000 as
http_request_timeout_seconds=3, and is un-gated: it passes against the
proxy, timing out at about three seconds and succeeding on the
fallback. test/uts/deviations.md removes its Failing Tests entry and
candidate issue I.3, records the HTTP options with the others as an
intentional naming-and-unit deviation, keeps the rest of #709 open, and
updates its counts for one fewer gated test and REST root cause.
This is a breaking change: passing an old name raises TypeError. Callers
should rename the option and keep its value, as UPDATING.md shows.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The two commits before this one rename the eight timing options with a
_seconds suffix. Options passes the keyword arguments it does not know
on to AuthOptions, so a 3.x name already raised TypeError at
construction, but with Python's bare "unexpected keyword argument",
which says nothing about the rename or the change of unit.
Options now checks for the eight 3.x names before anything else and
raises a TypeError naming the replacement. For the five options that
took milliseconds it also converts the value passed, for instance
"`disconnected_retry_timeout` was renamed to
`disconnected_retry_timeout_seconds` in 4.0 and is now in seconds
(15000 ms → 15)", falling back to the 3.x default where the value is
not a finite number; for the three HTTP options it says the unit is
unchanged. The factories reach it through Options, so it covers both
clients and Options itself. It is still a TypeError, so nothing that
raised before stops raising or raises something else, and a missing
credential is still reported first, as 40106.
UPDATING.md shows the messages and the eight renames together, and
test/uts/deviations.md notes the hint. No UTS test passes an old name,
so the counts do not change.

Options stored whatever it was given for a timing option, and nothing
checked it until it was used. A string or a negative number failed
later or not at all, and a timedelta passed to a realtime option was
accepted and then raised a TypeError inside the timer task, where it was
only logged, so the retry it was meant to schedule never ran.
Options now validates the eight _seconds options once their defaults are
resolved, and the setters of the three HTTP ones validate too. Each must
be a finite, non-negative int or float; a bool, a string, a negative
number, NaN, an infinity or a timedelta raises InvalidArgumentException
with status 400 and code 40000, the code push.admin.publish already uses
for invalid arguments, which is also a ValueError. A timedelta's message
says to pass its total_seconds(). Zero is accepted, and no magnitude is
warned about. None still means the default, since validation runs after
the defaults are resolved.
The factory docstrings name the 40000 and the TypeError a renamed
option raises. UPDATING.md and test/uts/deviations.md describe the
accepted values. No UTS test passes an invalid value, so the counts do
not change.
This is a breaking change: a client given an invalid timing option now
fails to construct instead of misbehaving later.

The PR changes eight timeout options to _seconds names, validates finite non-negative numeric values, converts values for internal millisecond timers, updates HTTP and realtime consumers, and migrates documentation and tests.

Timeout option migration
Layer / File(s)
Summary
Options contract and conversion ably/pubsub/types/options.py, ably/pubsub/transport/defaults.py
Timeout options now use seconds-based names and defaults. Legacy names raise TypeError. Invalid values raise InvalidArgumentException. Internal timer properties expose milliseconds.
HTTP and realtime timers now read the renamed seconds properties or converted millisecond properties.
Documentation and migration guidance CLAUDE.md, UPDATING.md, .claude/skills/uts-to-python/SKILL.md, ably/pubsub/server/*
Documentation describes the renamed options, units, defaults, validation, conversion, and migration errors.
Test updates test/unit/*, test/ably/*, test/uts/*
Tests use equivalent seconds values and add coverage for conversion, validation, rename errors, and defaults. The recorded deviation and test totals are updated.
The seconds-based migration is mergeable with bounded follow-up: extreme timeout values can raise unexpected exceptions or interrupt channel attachment, and one integration instruction still uses obsolete names. Normal timeout configurations are not implicated by these findings.

Update the integration timeout guidance to seconds.
Lines 948–951 still tell readers to pass realtimeRequestTimeout, disconnectedRetryTimeout and suspendedRetryTimeout as same-named client options in milliseconds. The new text at 898–902 says these options are seconds under *_seconds names. Following 948–951 passes realtime_request_timeout=3000, which _reject_renamed_timing_options rejects with TypeError. Replace the paragraph with the *_seconds names.

Reject oversized integers in validate_seconds before math.isfinite.
An integer too large for a float, such as http_request_timeout_seconds=10**400, passes the isinstance check and reaches math.isfinite. That call raises OverflowError, so the client constructor fails without the documented code 40000 InvalidArgumentException. Handle oversized integers in the validator, and raise the 40000 error for values that are rejected.

TK2a counts a token's ttl in milliseconds. A ttl given as a timedelta
was converted through total_seconds() and int(), which truncates, so
1,482 of the whole-millisecond values from 0 to 200,000 were sent one
millisecond short: timedelta(milliseconds=1001) was requested as 1000.
Both conversions did this, the one in create_token_request and the one
that sends the token params to an auth_url.
Both now go through ttl_ms, which divides by timedelta(milliseconds=1)
and so stays in integer arithmetic. A ttl given as a number is sent as
before. New unit tests check every millisecond up to 200 seconds and
both call sites. No UTS test changes state, so deviations.md does not
change.

Four breaking changes to the timing client options for 4.0.0, plus a fix for a
timedeltattl, one commit each. Every commit has an entry inUPDATING.md, updatestest/uts/deviations.mdwhere its counts change, and passesruff,test/unitandtest/utson its own.The timing options came in two units. The three HTTP options were seconds and the five others were milliseconds, with nothing in the names to tell them apart, while TO3l counts all of them in milliseconds. The decision for 4.0 is that all eight take seconds, as an int or a float, and each is renamed with a
_secondssuffix. Seconds is what a Python caller expects. The rename is what makes the migration loud:Optionspasses unknown keyword arguments on toAuthOptions, so an old name raisesTypeErrorat construction. A carried-overdisconnected_retry_timeout=15000fails at once, rather than silently meaning a retry about four hours away.realtime_request_timeoutrealtime_request_timeout_secondsdisconnected_retry_timeoutdisconnected_retry_timeout_secondssuspended_retry_timeoutsuspended_retry_timeout_secondschannel_retry_timeoutchannel_retry_timeout_secondsfallback_retry_timeoutfallback_retry_timeout_secondshttp_open_timeouthttp_open_timeout_secondshttp_request_timeouthttp_request_timeout_secondshttp_max_retry_durationhttp_max_retry_duration_secondsCommits
*_seconds. The defaults are now 10, 15, 30, 15 and 600, and they read back fromOptionsunder the new names. The clock API still counts milliseconds.Optionsconverts each option in one place,seconds_to_ms, which sits behind a private_<option>_msproperty. The connection manager, the channel timers, the transport's idle timeout and the HTTP fallback cache all read those properties.seconds_to_msrounds to the microsecond rather than truncating, so0.0015is 1.5 ms and0.1is exactly 100 ms. Theping()timeout runs on the event loop's clock, so it reads the seconds directly. Every UTS test that sets one of these options now passes the spec's value divided by 1000. Migration: rename the option and divide the value by 1000, or passtimedelta(...).total_seconds().*_seconds. Only the names change; the unit and the defaults stay the same. The httpxTimeoutand the RSC15 retry budget read the new names, and so do theHttpproperties.rest/proxy/RSC15l2/timeout-triggers-fallback-0was gated because it passed the spec'shttpRequestTimeout: 3000straight through as 3000 seconds. It now passeshttp_request_timeout_seconds=3and is un-gated: against the proxy it times out at about 3 s and succeeds on the fallback. Its Failing Tests entry and candidate issue I.3 are removed. Migration: rename the option and keep the value.TypeError, so nothing that raised before stops raising. For a millisecond option the message converts the value passed, for exampleTypeError: `disconnected_retry_timeout` was renamed to `disconnected_retry_timeout_seconds` in 4.0 and is now in seconds (15000 ms → 15). For an HTTP option it says the unit is unchanged. A missing credential is still reported first, as 40106. Migration: none beyond the renames; the message tells you the fix.intorfloat. Abool, a string, a negative value, NaN, an infinity or atimedeltaraisesInvalidArgumentExceptionwith 400/40000. That is pubsub: breaking changes to exceptions #737's subclass, and also aValueError. The code followspush.admin.publish, which uses 40000 for invalid non-credential arguments; 40106 is for credentials. Atimedeltaused to be accepted and then raised inside the timer task, so the retry never fired. Its error now says to passtotal_seconds(). The three HTTP setters validate too.Nonestill means the default, and zero is accepted. There are no magnitude warnings. Migration: fix any invalid value; atimedeltaneeds.total_seconds().timedeltattl to the millisecond. Tokenttlstays int ms, but attlgiven as atimedeltawas converted throughtotal_seconds()andint(), which truncates. As a result, 1,482 of the whole-millisecond values from 0 to 200,000 were sent one short:timedelta(milliseconds=1001)was requested as 1000. Whole seconds were unaffected. Both conversions, increate_token_requestand in the params sent to anauth_url, now go throughttl_ms, which divides bytimedelta(milliseconds=1)and so stays in integer arithmetic. A ttl given as a number is sent as before. Migration: none.Scoped down or skipped
ttl(TokenParams/TokenRequest),ConnectionDetails(max_idle_interval,connection_state_ttl),Auth.time_offset, all timestamps, and the round tripping()returns. They are protocol values rather than client configuration.Defaultsare unchanged:connect_timeout,disconnect_timeout,suspended_timeout,comet_*andconnection_state_ttl. None of them is the default of one of the eight options. Only the eight defaults moved to*_secondsnames.AuthOptionshas none (query_timeis a bool), andmax_message_sizeandhttp_max_retry_countare not durations.Tests

Every tier was run separately undercaffeinatewith a watchdog, and every run completed on the first attempt:v4-channels(72d00f8)RUN_DEVIATIONSRUN_DEVIATIONS=1test/unitThe outcome of every test was diffed against the parent's, in both modes. Commit 1 matches the parent test for test. From commit 2 on, the only difference is that
test_rsc15l2_timeout_triggers_fallbackpasses instead of being skipped or failing. Thedeviations.mdfigures were re-measured at each commit from the junit reports and the# UTS:comments, not adjusted from the parent's. They change only at commit 2:New tests in
