Enable LFS (Large File Storage) in GitLab

Refer to official docs: https://docs.gitlab.com/ce/administration/lfs/manage_large_binaries_with_git_lfs.html

Requirements

  • Git LFS is supported in GitLab starting with version 8.2
  • Git LFS must be enabled under project settings
  • Git LFS client version 1.0.1 and up  

1. Enable LFS on GitLab Server

a). Configuration for Omnibus installations In 

/etc/gitlab/gitlab.rb:

# Change to true to enable lfs - enabled by default if not defined
gitlab_rails['lfs_enabled]=false

# Optionally, change the storage path location. Defaults to
# `#{gitlab_rails['shared_path']}/lfs-objects`. Which evaluates to
# `/var/opt/gitlab/gitlab-rails/shared/lfs-objects` by default.
gitlab_rails['lfs_storage_path']"/mnt/storage/lfs-objects"

b). Configuration for installations from source In 

config/gitlab.yml:

# Change to true to enable lfs
  lfs:
    enabled: false
    storage_path:/mnt/storage/lfs-objects

2. Submit LFS object to Git project Initialize LFS support in the project, and mark the file extensions for tracking as LFS object:

$ git clone [email protected]:group/project.git
$ git lfs install # initialize the Git LFS project
$ git lfs track "*.out" "*.so" "*.dll" "*.meta" "*.dat" "/bin/**" # select the file extensions that you want to treat as large files

Details for lfs track partten please refer to : https://git-scm.com/docs/gitignore#_pattern_format

Make sure that .gitattributes is tracked by Git. Otherwise Git LFS will not be working properly for people cloning the project:

$ git add .gitattributes
$ git commit -m "Submit lfs settings"
$ git push -u origin master

  An LFS icon is shown on files tracked by Git LFS to denote if a file is stored as a blob or as an LFS pointer. Example:

3. Pull LFS object from Git project Other user need to install git-lfs package and execute git lfs pull after clone the prjoect:

$ git clone [email protected]:group/project.git
$ git lfs pull

General “git pull” will only download index data of LFS object:

# cat appframed.out 
version https://git-lfs.github.com/spec/v1
oid sha256:e8eef08ead6e6f3ad021ba798b35d2da59f804e9dbe8aace7ed4b66d3ede1054
size 6766944

In jenkins, it needs to enable “

Git LFS pull after checkout” addtional behavior for Git repo.

Gitlab Omnisharp package – Change LDAP DN for external user

Scenario:

Change DN from “cn=李小李,ou=IT中心,ou=XX公司,dc=xx,dc=com” to “cn=李小李,ou=HR Dept,ou=XX公司,dc=xx,dc=com” for user #11.

Step 1 – Connect to boundled PostgreSQL database

# sudo gitlab-psql -d gitlabhq_production
psql (10.9)
Type "help" for help.

gitlabhq_production=#

Refer to: https://docs.gitlab.com/omnibus/settings/database.html#connecting-to-the-bundled-postgresql-database

Step 2 – Search user DN by user id in the psql shell

gitlabhq_production=# select * from identities where provider = 'ldapmain' and user_id = 11;
 id |                           extern_uid                           | provider | user_id |         created_at         |         updated_at         | saml_provider_id | secondary_extern_uid 
----+----------------------------------------------------------------+----------+---------+----------------------------+----------------------------+------------------+----------------------
  9 | cn=李小李,ou=IT中心,ou=XX公司,dc=xx,dc=com | ldapmain |      11 | 2018-06-27 15:01:13.457313 | 2019-12-19 03:26:00.777429 |                  | 
(1 row)

gitlabhq_production=#

Step 3 – Update user DN

update identities set extern_uid = CONCAT('cn=',E'\u674e',E'\u5c0f',E'\u674e',',ou='HR Dept',',ou=XX',E'\u516c',E'\u53f8',',dc=q1oa,dc=com') where provider = 'ldapmain' and user_id = 11;
UPDATE 1
gitlabhq_production=#

Notes: You can’t input chinese characters in the psql shell, so you need encode the chinese chars in unicode format and use CONCAT function to concat ascii and unicode characters in the update SQL statement. Refer to: https://kb.objectrocket.com/postgresql/use-psql-to-insert-a-record-with-unicode-characters-845

PS: In GitLab ver 12.2.5 (09f8edbc29a), it is able to modify user’s DN by : Admin Area -> Overview -> Users -> find user and switch to “Identities” tab -> Edit
