From ead60686e810df4b49bf19f4f113b48f16ae560f Mon Sep 17 00:00:00 2001 From: khall Date: Wed, 4 Oct 2017 12:26:04 -0700 Subject: Replace variation key use with SHA256 of key to prevent long filenames If a variant has a large set of options associated with it, the generated filename will be too long, causing Errno::ENAMETOOLONG to be raised. This change replaces those potentially long filenames with a much more compact SHA256 hash. Fixes #30662. --- activestorage/app/models/active_storage/variant.rb | 2 +- activestorage/test/models/variant_test.rb | 5 +++++ 2 files changed, 6 insertions(+), 1 deletion(-) (limited to 'activestorage') diff --git a/activestorage/app/models/active_storage/variant.rb b/activestorage/app/models/active_storage/variant.rb index 54685b4c0e..90a3605331 100644 --- a/activestorage/app/models/active_storage/variant.rb +++ b/activestorage/app/models/active_storage/variant.rb @@ -50,7 +50,7 @@ class ActiveStorage::Variant # Returns a combination key of the blob and the variation that together identifies a specific variant. def key - "variants/#{blob.key}/#{variation.key}" + "variants/#{blob.key}/#{Digest::SHA256.hexdigest(variation.key)}" end # Returns the URL of the variant on the service.
