# bona fide bug in git 2.50.1
|
|
# bug when using:
|
|
# git subtree split ...
|
|
# git subtree needs to review a set of commits, filtering for those that
|
|
# intersect with target prefix. e.g.
|
|
# git subtree split --prefix=xo-indentlog -b _demux/xo-indentlog
|
|
#
|
|
# 1. the split function is building a map old->new from commits in current repo,
|
|
# to a smaller set of commits in the split repo:
|
|
# it intends finding commits that intersect with anything in prefix,
|
|
# adding old->new map entries for each such commit.
|
|
#
|
|
# 2. subtree (incorrectly?) decides it needs to cache a commit that does not
|
|
# actually intersect prefix. Calls its cache_set() twice with the same newrev.
|
|
# 2nd calls aborts, assumes cache should not already contain an oldrev key.
|
|
#
|
|
# 3. fix is to permit multiple calls to cache_set() with the same old->new
|
|
# mapping. Keep the abort if called twice with different target commits.
|
|

# nix-provided GPU libraries only work out-of-the-box on nixos.

# For non-nixos build, need to use host-provided versions of these libraries.
|
|
# Complications:
|
|
# 1. host location is likely something like /usr/lib/x86_64-linux-gnu,
|
|
# in which case interposing that directly will change link behavior for unrelated shared libraries
|
|
# (e.g. risk getting stale non-nix libc.so etc). Use a curated symlink directory to finesse.
|
|
# 2. host-installed libraries may not set RUNPATH (they don't need to if installed in system-wide default location).
|
|
# We need to also add nix-store LD_LIBRARY_PATH entries for indirect dependencies of system-provided libraries.
