From 30a0d6288d685ac9d0dbb274f011dc65363ea261 Mon Sep 17 00:00:00 2001 From: Anna Henningsen Date: Sat, 28 May 2016 00:10:28 +0200 Subject: [PATCH] deps: float gyp patch for long filenames Pulling in https://codereview.chromium.org/2019133002/ in its current state, as gyp seems to be largely abandoned as a project. Original commit message: Hash intermediate file name to avoid ENAMETOOLONG Hash the intermediate Makefile target used for multi-output rules so that it still works when the involved file names are very long. Since the intermediate file's name is effectively arbitrary, this does not come with notable behavioural changes. The `import hashlib` boilerplate is taken directly from `xcodeproj_file.py`. Concretely, this makes the V8 inspector build currently fail when long pathnames are involved, notably when using ecryptfs which has a lower file name length limit.
