Solution to GitLab file size larger than 4G that cannot be uploaded

In the process of using GitLab for code warehouse management, we often encounter the problem of limited upload file size. The most common one is that GitLab files are larger than 4G and cannot be uploaded. This problem has been bothering many developers. The following is a detailed introduction to the solution to this problem.

1. The reason for GitLab file size limit

GitLab is a version control system based on Git, and its file management function is also based on Git's object library. Git's object repository is the "actual content" of a Git repository, and all files, directories, and version history are stored in the repository. Under normal circumstances, there is no problem with the file size limit of the Git library. However, when uploading large files, there will be situations where the Git library cannot handle it, and "fatal: the remote end hung up unexpectedly" will often be reported.

The reason for this problem is that the GitLab server does not have enough memory to cache the uploaded large files, resulting in a memory overflow on the server during the upload process. In addition, GitLab's default upload limit is also 4G. If the file exceeds this limit, you will get an error message that refuses to upload. Therefore, you need to pay special attention to this limitation when uploading large files exceeding 4G.

2. Methods to solve the GitLab file size limit

When uploading files with a GitLab file size exceeding 4G, there are several methods to solve this problem:

(1)Git LFS

Git LFS (Git Large File Storage) is an extension of Git, which solves the problem of Git processing large files. Using Git LFS, large files can be stored in external storage, thereby alleviating the storage pressure on the server. Download and install Git LFS from the Git LFS official website, and then configure Git LFS into the local Git library. In the local Git repository, add the large file that needs to be uploaded and submit it. At this point, Git keeps a pointer to the file instead of uploading the entire file to the server. Then, use Git LFS to upload the pointer file pointing to the large file. In this way, Git LFS will upload the pointer file pointing to the large file to the server and ensure that the large file is in external storage.

(2) Split files

Split large files into small files. Before splitting a file, you need to use a tool to calculate the checksum (MD5) value of the file to ensure that there will be no errors after the file is split. Then, upload the split small files to the GitLab server. When you need to use the large file, just merge the divided small files.

(3) Zip compression

Compress large files into zip files for upload. This method can save storage space while also solving the problem of uploading large files. However, when you need to use the large file, you need to manually unzip the file.

In general, the above methods can solve the problem that GitLab files larger than 4G cannot be uploaded. However, when choosing a method, you need to choose based on your own needs. If you use large files frequently, using Git LFS is the best way; if you use large files once, you can choose to split the file or compress the file.
