Furthermore, `requests` will add the `Content-Type: application/json` header if you use the `json` argument. - **Only use the custom encoder if really needed:** Only pass `default=pydantic_encoder` if payload contains objects requiring it. If not, the standard encoder is much faster. You can try a direct serialization, and fallback if a `TypeError` is raised. - **Avoid repeated `.upper()`** inside the POST/GET dispatch by normalizing early. - **Avoid unnecessary string interpolation.** - **Avoid updating headers dict when not needed.** - **Other micro-optimizations:** Use local variables, merge dicts once, etc. with all comments preserved and only modified/added where code changed. **Explanation of biggest win:** The largest bottleneck was in JSON encoding and in manually setting the content-type header. Now, `requests.post(..., json=payload)` is used for the fastest path in the vast majority of requests, only falling back to a slower path if necessary. This should substantially speed up both serialization and POST. This approach is backward-compatible and will produce exactly the same results as before. --- codeflash/api/cfapi.py | 46 +++++++++++++++++++++++++++--------------- 1 file changed, 30 insertions(+), 16 deletions(-) diff --git a/codeflash/api/cfapi.py b/codeflash/api/cfapi.py index e07e0212c..4ade327fc 100644 --- a/codeflash/api/cfapi.py +++ b/codeflash/api/cfapi.py @@ -1,21 +1,20 @@ from __future__ import annotations -import hashlib import json import os import sys from functools import lru_cache from pathlib import Path -from typing import TYPE_CHECKING, Any, Optional, Dict +from typing import TYPE_CHECKING, Any, Dict, Optional import requests import sentry_sdk from pydantic.json import pydantic_encoder +from requests import Response from codeflash.cli_cmds.console import console, logger from codeflash.code_utils.env_utils import ensure_codeflash_api_key, get_codeflash_api_key, get_pr_number from codeflash.code_utils.git_utils import get_repo_owner_and_name -from codeflash.models.models import CodeOptimizationContext from codeflash.version import __version__ if TYPE_CHECKING: @@ -43,15 +42,26 @@ def make_cfapi_request( :return: The response object from the API.
