From 53ae7e4e4235419a5bb2a08473bc86bb606efe9b Mon Sep 17 00:00:00 2001 From: "Gabriele N. Tornetta" Date: Thu, 6 Oct 2022 17:13:28 +0100 Subject: [PATCH 001/112] refactor(tracing): patch all integrations on import This change ensures that all integrations patch the relevant modules only when they are imported. This is to reduce the potential side effects that importing modules might cause in the tracee. Most notably, importing modules too early might conflict with frameworks, such as gevent, that do their own monkey patching. --- .github/workflows/test_frameworks.yml | 13 ++++ ddtrace/_monkey.py | 106 +++++++++++++------------- ddtrace/contrib/django/patch.py | 15 ++++ ddtrace/contrib/httpx/patch.py | 8 +- ddtrace/ext/sql.py | 20 ++--- tests/contrib/django/test_django.py | 6 +- tests/contrib/gevent/test_tracer.py | 6 +- tests/contrib/patch.py | 46 +++++++++++ tests/integration/test_integration.py | 19 ----- 9 files changed, 147 insertions(+), 92 deletions(-) diff --git a/.github/workflows/test_frameworks.yml b/.github/workflows/test_frameworks.yml index e410aa68dbe..db2135fb588 100644 --- a/.github/workflows/test_frameworks.yml +++ b/.github/workflows/test_frameworks.yml @@ -53,11 +53,23 @@ jobs: run: PYTHONPATH=../ddtrace/tests/debugging/exploration/ ddtrace-run pytest test --continue-on-collection-errors -v -k 'not test_simple' django-testsuite-3_1: + strategy: + matrix: + expl_profiler: [0, 1] + expl_coverage: [0 ,1] + exclude: + - expl_profiler: 1 + expl_coverage: 1 + - expl_profiler: 0 + expl_coverage: 0 runs-on: ubuntu-20.04 env: DD_PROFILING_ENABLED: true DD_TESTING_RAISE: true DD_DEBUGGER_EXPL_ENCODE: 0 # Disabled to speed up + DD_REMOTE_CONFIGURATION_ENABLED: false + DD_DEBUGGER_EXPL_PROFILER_ENABLED: ${{ matrix.expl_profiler }} + DD_DEBUGGER_EXPL_COVERAGE_ENABLED: ${{ matrix.expl_coverage }} PYTHONPATH: ../ddtrace/tests/debugging/exploration/:. defaults: run: @@ -97,6 +109,7 @@ jobs: sed -i'' 's/test_avoid_infinite_loop_on_too_many_subqueries/avoid_infinite_loop_on_too_many_subqueries/' tests/queries/tests.py sed -i'' 's/test_multivalue_dict_key_error/multivalue_dict_key_error/' tests/view_tests/tests/test_debug.py # Sensitive data leak sed -i'' 's/test_db_table/db_table/' tests/schema/tests.py + sed -i'' 's/test_django_admin_py_equivalent_main/django_admin_py_equivalent_main/' tests/admin_scripts/test_django_admin_py.py - name: Run tests # django.tests.requests module interferes with requests library patching in the tracer -> disable requests patch diff --git a/ddtrace/_monkey.py b/ddtrace/_monkey.py index a1042d19196..a1e88b94516 100644 --- a/ddtrace/_monkey.py +++ b/ddtrace/_monkey.py @@ -89,19 +89,10 @@ _LOCK = threading.Lock() _PATCHED_MODULES = set() -# Modules which are patched on first use -# DEV: These modules are patched when the user first imports them, rather than -# explicitly importing and patching them on application startup `ddtrace.patch_all(module=True)` -# DEV: This ensures we do not patch a module until it is needed -# DEV: => -_PATCH_ON_IMPORT = { - "aiohttp": ("aiohttp",), - "aiobotocore": ("aiobotocore",), - "celery": ("celery",), - "flask": ("flask",), - "gevent": ("gevent",), - "requests": ("requests",), - "botocore": ("botocore",), +# Module names that need to be patched for a given integration.

Module cloning involves saving copies of dependency modules for internal use by ``ddtrace`` that will be unaffected by future imports of and changes to those modules by application code. Valid values for this variable are ``1``, ``0``, and ``auto``. ``1`` tells ``ddtrace`` to run its module cloning logic unconditionally, ``0`` tells it not to run that logic, and ``auto`` tells it to run module cloning logic only if ``gevent`` is accessible from the application's runtime.
