# Speed up all builds by not checking if output files have been modified. Lets you make changes to
|
||
|
|
# the output tree without triggering a build for local debugging. For example, you can modify
|
||
|
|
# [rules_js](https://github.com/aspect-build/rules_js) 3rd party npm packages in the output tree
|
||
|
|
# when local debugging.

# Don't apply `--noremote_upload_local_results` and `--noremote_accept_cached` to the disk cache.

# If you have both `--noremote_upload_local_results` and `--disk_cache`, then this fixes a bug where
|
||
|
|
# Bazel doesn't write to the local disk cache as it treats as a remote cache.

# Do not build runfiles symlink forests for external repositories under

# Some actions are always IO-intensive but require little compute. It's wasteful to put the output
|
||
|
|
# in the remote cache, it just saturates the network and fills the cache storage causing earlier
|
||
|
|
# evictions. It's also not worth sending them for remote execution.
|
||
|
|
# For actions like PackageTar it's usually faster to just re-run the work locally every time.
|
||
|
|
# You'll have to look at an execution log to figure out what other action mnemonics you care about.
|
||
|
|
# In some cases you may need to patch rulesets to add a mnemonic to actions that don't have one.
