How to limit file size on commit?
提交时是否有限制文件大小的选项?
例如:文件大小超过 500K 会产生警告。超过 10M 的文件大小将停止提交。
我完全了解这个问题,从技术上讲,这个问题是重复的,但答案只提供了一个推送解决方案,这对我的要求来说为时已晚。
这个预提交钩子会做文件大小检查:
.git/hooks/pre-commit
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | #!/bin/sh hard_limit=$(git config hooks.filesizehardlimit) soft_limit=$(git config hooks.filesizesoftlimit) : ${hard_limit:=10000000} : ${soft_limit:=500000} list_new_or_modified_files() { git diff --staged --name-status|sed -e '/^D/ d; /^D/! s/.\\s\\+//' } unmunge() { local result="${1#"}" result="${result%"}" env echo -e"$result" } check_file_size() { n=0 while read -r munged_filename do f="$(unmunge"$munged_filename")" h=$(git ls-files -s"$f"|cut -d' ' -f 2) s=$(git cat-file -s"$h") if ["$s" -gt $hard_limit ] then env echo -E 1>&2"ERROR: hard size limit ($hard_limit) exceeded: $munged_filename ($s)" n=$((n+1)) elif ["$s" -gt $soft_limit ] then env echo -E 1>&2"WARNING: soft size limit ($soft_limit) exceeded: $munged_filename ($s)" fi done [ $n -eq 0 ] } list_new_or_modified_files | check_file_size |
以上脚本必须保存为
默认的软(警告)和硬(错误)大小限制设置为 500,000 和 10,000,000 字节,但可以分别通过
1 2 | $ git config hooks.filesizesoftlimit 100000 $ git config hooks.filesizehardlimit 4000000 |
@Leon\\ 脚本的更短的 bash 特定版本,它以人类可读的格式打印文件大小。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | #!/bin/bash hard_limit=$(git config hooks.filesizehardlimit) soft_limit=$(git config hooks.filesizesoftlimit) : ${hard_limit:=10000000} : ${soft_limit:=1000000} status=0 bytesToHuman() { b=${1:-0}; d=''; s=0; S=({,K,M,G,T,P,E,Z,Y}B) while ((b > 1000)); do d="$(printf".%01d" $((b % 1000 * 10 / 1000)))" b=$((b / 1000)) let s++ done echo"$b$d${S[$s]}" } # Iterate over the zero-delimited list of staged files. while IFS= read -r -d '' file ; do hash=$(git ls-files -s"$file" | cut -d ' ' -f 2) size=$(git cat-file -s"$hash") if (( $size > $hard_limit )); then echo"Error: Cannot commit '$file' because it is $(bytesToHuman $size), which exceeds the hard size limit of $(bytesToHuman $hard_limit)." status=1 elif (( $size > $soft_limit )); then echo"Warning: '$file' is $(bytesToHuman $size), which exceeds the soft size limit of $(bytesToHuman $soft_limit). Please double check that you intended to commit this file." fi done < <(git diff -z --staged --name-only --diff-filter=d) exit $status |
与其他答案一样,这必须以执行权限保存为
示例输出:
1 | Error: Cannot commit 'foo' because it is 117.9MB, which exceeds the hard size limit of 10.0MB. |
你需要实现你已经在
从文档中,我们了解到预提交挂钩
takes no parameters, and is invoked before obtaining the proposed commit log message and making a commit. Exiting with a non-zero status from this script causes the git commit command to abort before creating a commit.
基本上,调用钩子来检查是否允许用户提交他的更改。
eis原来在其他帖子上做的脚本变成了

只是想评论@Leon 提供的解决方案太棒了。如果一个空目录开始尝试被跟踪,我遇到了一个小障碍,它中止了。所以我不得不添加
1 | [ -d"$f" ] && continue |
在
我更愿意发表评论,因为这不是答案,但我没有声誉积分。
注意:我知道 git \\'ignores\\' 目录,但显然不是在预提交挂钩运行之前。
有一个通用的预提交钩子。您可以编写一个脚本来检查文件大小,然后接受或拒绝提交。然而,Git 让用户能够从命令行类型"git help hooks"中绕过检查以获取更多信息。这是关于预提交挂钩的相关信息。
预提交
这个钩子由 git commit 调用,可以通过 --no-verify 选项绕过。它不带参数,并在获取建议的提交日志消息并进行提交之前调用。从此脚本中以非零状态退出会导致 git 提交中止。
