+Subject: [PATCH] test: wiremock: raise the server start timeout to 120s
+
+WiremockClient waits WIREMOCK_START_MAX_RETRY_COUNT seconds (12) for the
+standalone server to answer /__admin/health, then fails the test. On the
+riscv64 runners a JVM start plus WireMock/Jetty init routinely exceeds that
+when several pytest-xdist workers each spin up their own server, so ~10 of
+the auth/oauth/redirect tests error out nondeterministically while the rest
+of the same suite passes.
+
+The loop returns as soon as the health check succeeds, so a larger ceiling
+costs nothing on faster hardware.

+Subject: [PATCH] test: detect_platforms: raise the generous timeout from 1s to
+ 30s
+
+detect_platforms() runs its six probes in a ThreadPoolExecutor and labels
+any that miss platform_detection_timeout_seconds with a "<name>_timeout"
+suffix. The tests that want no timeout label at all pass 1 second, with an
+inline comment saying the value is only there "to make sure no Thread-based
+timeout messes the results".
+
+On the riscv64 runners 1 second is not generous enough: has_aws_identity
+builds a boto3 STS client, and botocore's first service-model load, running
+alongside three other pytest-xdist workers, overshoots the budget. The
+future is then cancelled and test_no_platforms_detected sees
+['has_aws_identity_timeout'] instead of []. The four "not true" cases of
+test_platform_detection_disable_env_var_values assert the same empty list
+and are exposed the same way.
+
+csp_helpers patches urllib3's HTTPConnection.request to raise ConnectTimeout
+outright, so no probe ever waits on the network and a larger ceiling adds no
+wall-clock time anywhere. Sites that deliberately exercise the timeout path
+(None, 0, EXPECTED_MAX_TIMEOUT_FOR_PLATFORM_DETECTION) are left alone.

+Subject: [PATCH] test: auth: fix the mock_cnt race that test_auth_mfa's
+ timeout case leaves behind
+
+Auth.authenticate() runs the MFA wait in a daemon Thread and gives up on it
+with t.join(timeout=timeout), so the request mock keeps running after the
+call returns. test_auth_mfa's third case relies on exactly that: the mock's
+mock_cnt == 1 branch sleeps 10 seconds, the test passes timeout=1, and the
+join returns while that thread is still sleeping.
+
+The abandoned thread then falls through to `mock_cnt += 1` at the bottom of
+the mock, roughly nine seconds later. By that time the fourth case has
+already set `mock_cnt = 2` to select the "data is None" response, so the
+stray increment turns it into 3, the mock returns the empty else-branch
+dict, and Auth.authenticate() raises KeyError: 'data' instead of the
+snowflake.connector.errors.Error the test expects.
+
+Whether the increment lands inside the fourth case is pure timing. It never
+does on a fast machine, which is why this only shows up where the fourth
+case's setup takes longer than the rest of the sleep. It is the same race
+the test is already skipped for on Windows.
+
+Read and advance mock_cnt in one step at the top of the mock instead, before
+the sleep, so a call's counter effect is complete before the caller can walk
+away from it. Branch selection is unchanged: calls still see 0, 1, 2, ... in
+order.
+
+Reproducible anywhere by inserting `time.sleep(11)` after the fourth case's
+`mock_cnt = 2`: KeyError: 'data' before this change, passing after.
+
+Upstream-Status: To upstream [not submitted yet; the race is upstream's own, not riscv64-specific -- the existing IS_WINDOWS skip documents it]

+Subject: [PATCH] test: util: raise the get_application_path timing-regression
+ threshold from 1ms to 10ms
+
+test_get_application_path_is_fast_on_deep_call_stacks asserts the average
+wall-clock time of get_application_path() at a 150-frame-deep call stack
+stays under a hardcoded 1.0ms, guarding against a regression to an
+inspect.stack()-based implementation that reads every frame's source file
+(GH-2908 / SNOW-3691001).
+
+On this repo's shared riscv64 runners the same frame-walking implementation
+averages 2.286ms (observed on Build 4.7.4 cp312), 2.3x the threshold, with
+no regression to the slow inspect.stack() path: it is plain per-instruction
+cost on this architecture plus load from other concurrent matrix jobs on
+the same shared runner pool. Raise the ceiling to 10ms, well above the one
+observed sample, while still catching the ~100-500ms regression the test
+was written to guard against.
+
+Upstream-Status: Inappropriate [riscv64 runner is slower per-instruction than upstream's CI hosts, and shared with concurrent matrix jobs; the 1ms threshold assumes faster/dedicated hardware]

+Subject: [PATCH] test: cache: sleep before the final mtime-advancing save in
+ test_file_is_not_updated
+
+test_file_is_not_updated writes the cache file three times and checks
+os.path.getmtime() strictly advances each time a write happens. Before the
+second write-then-assert-greater pair (line 557/561 upstream) the test
+already sleeps 0.1s to guarantee the filesystem's mtime clock ticks forward
+between writes. The third write-then-assert-greater pair (triggered by
+advancing the mocked snowflake.connector.cache.now() past entry_lifetime)
+has no such sleep, even though the write it precedes still hits the real
+filesystem clock, not the mocked one.
+
+On this repo's riscv64 runners the two real-wall-clock writes can land
+within the same mtime tick, making the final
+`os.path.getmtime(tmp_cache_file) > second_updated_time` assertion fail
+with equal values (e.g. run 35440238662, job
+Build snowflake-connector-python 4.7.4 cp313-manylinux_riscv64). Add the
+same 0.1s sleep used earlier in this test before the last write, matching
+the established pattern.
+
+Upstream-Status: Inappropriate [riscv64 runner filesystem mtime resolution/timing is coarser than upstream's CI hosts; the test already sleeps before an analogous write two lines earlier but is missing the same sleep before this one]

+Subject: [PATCH] test: wiremock: raise the server start timeout to 120s
+
+WiremockClient waits WIREMOCK_START_MAX_RETRY_COUNT seconds (12) for the
+standalone server to answer /__admin/health, then fails the test. On the
+riscv64 runners a JVM start plus WireMock/Jetty init routinely exceeds that
+when several pytest-xdist workers each spin up their own server, so ~10 of
+the auth/oauth/redirect tests error out nondeterministically while the rest
+of the same suite passes.
+
+The loop returns as soon as the health check succeeds, so a larger ceiling
+costs nothing on faster hardware.

+Subject: [PATCH] test: detect_platforms: raise the generous timeout from 1s to
+ 30s
+
+detect_platforms() runs its six probes in a ThreadPoolExecutor and labels
+any that miss platform_detection_timeout_seconds with a "<name>_timeout"
+suffix. The tests that want no timeout label at all pass 1 second, with an
+inline comment saying the value is only there "to make sure no Thread-based
+timeout messes the results".
+
+On the riscv64 runners 1 second is not generous enough: has_aws_identity
+builds a boto3 STS client, and botocore's first service-model load, running
+alongside three other pytest-xdist workers, overshoots the budget. The
+future is then cancelled and test_no_platforms_detected sees
+['has_aws_identity_timeout'] instead of []. The four "not true" cases of
+test_platform_detection_disable_env_var_values assert the same empty list
+and are exposed the same way.
+
+csp_helpers patches urllib3's HTTPConnection.request to raise ConnectTimeout
+outright, so no probe ever waits on the network and a larger ceiling adds no
+wall-clock time anywhere. Sites that deliberately exercise the timeout path
+(None, 0, EXPECTED_MAX_TIMEOUT_FOR_PLATFORM_DETECTION) are left alone.

+Subject: [PATCH] test: auth: fix the mock_cnt race that test_auth_mfa's
+ timeout case leaves behind
+
+Auth.authenticate() runs the MFA wait in a daemon Thread and gives up on it
+with t.join(timeout=timeout), so the request mock keeps running after the
+call returns. test_auth_mfa's third case relies on exactly that: the mock's
+mock_cnt == 1 branch sleeps 10 seconds, the test passes timeout=1, and the
+join returns while that thread is still sleeping.
+
+The abandoned thread then falls through to `mock_cnt += 1` at the bottom of
+the mock, roughly nine seconds later. By that time the fourth case has
+already set `mock_cnt = 2` to select the "data is None" response, so the
+stray increment turns it into 3, the mock returns the empty else-branch
+dict, and Auth.authenticate() raises KeyError: 'data' instead of the
+snowflake.connector.errors.Error the test expects.
+
+Whether the increment lands inside the fourth case is pure timing. It never
+does on a fast machine, which is why this only shows up where the fourth
+case's setup takes longer than the rest of the sleep. It is the same race
+the test is already skipped for on Windows.
+
+Read and advance mock_cnt in one step at the top of the mock instead, before
+the sleep, so a call's counter effect is complete before the caller can walk
+away from it. Branch selection is unchanged: calls still see 0, 1, 2, ... in
+order.
+
+Reproducible anywhere by inserting `time.sleep(11)` after the fourth case's
+`mock_cnt = 2`: KeyError: 'data' before this change, passing after.
+
+Upstream-Status: To upstream [not submitted yet; the race is upstream's own, not riscv64-specific -- the existing IS_WINDOWS skip documents it]

+
+test_get_application_path_is_fast_on_deep_call_stacks asserts the average
+wall-clock time of get_application_path() at a 150-frame-deep call stack
+stays under a hardcoded 1.0ms, guarding against a regression to an
+inspect.stack()-based implementation that reads every frame's source file
+(GH-2908 / SNOW-3691001).
+
+On this repo's shared riscv64 runners the same frame-walking implementation
+averages 2.286ms (observed on Build 4.7.4 cp312), 2.3x the threshold, with
+no regression to the slow inspect.stack() path: it is plain per-instruction
+cost on this architecture plus load from other concurrent matrix jobs on
+the same shared runner pool. Raise the ceiling to 10ms, well above the one
+observed sample, while still catching the ~100-500ms regression the test
+was written to guard against.
+
+Upstream-Status: Inappropriate [riscv64 runner is slower per-instruction than upstream's CI hosts, and shared with concurrent matrix jobs; the 1ms threshold assumes faster/dedicated hardware]

+On this repo's riscv64 runners the two real-wall-clock writes can land
+within the same mtime tick, making the final
+`os.path.getmtime(tmp_cache_file) > second_updated_time` assertion fail
+with equal values (e.g. run 35440238662, job
+Build snowflake-connector-python 4.7.4 cp313-manylinux_riscv64). Add the
+same 0.1s sleep used earlier in this test before the last write, matching
+the established pattern.
+
+Upstream-Status: Inappropriate [riscv64 runner filesystem mtime resolution/timing is coarser than upstream's CI hosts; the test already sleeps before an analogous write two lines earlier but is missing the same sleep before this one]
