| # Size Checker |
| A executable that checks if a build exceeds its allocated space limit. |
| |
| |
| ## Local Run |
| Run the following command in the output directory: |
| |
| ```bash |
| fx size_checker --build-dir . |
| ``` |
| |
| ## Space Limit |
| The space limit is governed by the `size_checker.json`, which is generated based on the `size_checker_input` argument. |
| |
| To enforce the size limit, build product with the suffix `_size_limits` (if |
| such file exists) instead of the normal product.gni. |
| |
| For a full description of its argument, see `cmd/BUILD.gn`. |
| |
| ## Dependencies |
| |
| The test has many hardcoded dependencies, so you only need to pass in the build directory. |
| |
| It expects to find the following files in the output directory: |
| |
| ``` |
| blobs.json |
| gen/build/images/blob.manifest.list |
| size_checker.json |
| ``` |
| |
| Additionally, it also depends on the `blobs.json` of each package to be in the same directory as the `meta.far` file. |
