fatal: the remote end hung2. 解决
问了Qwen等LLM，没用，还是stackoverflow
根据：
- Git push failure while pushing a large respository of code
- Git error: RPC failed; HTTP 400 curl 22 The requested URL returned error: 400 send-pack: unexpected disconnect while reading sideband packet
执行以下操作：
bash
# 方法1 把要push的内容分多次push，先回退，再分多次提交
# 方法2，临时修改 buffer size，提交完再改回去，防止吃内存
git config http.postBuffer 524288000
git pull && git push
git config --unset http.postBuffer3. 原因探索
不一定是网络原因，而是 buffer size的问题
