# Test Import Project
|
|
|
|
For testing, we can import our own [GitLab CE](https://gitlab.com/gitlab-org/gitlab-foss/) project (named `gitlabhq` in this case) under a group named `qa-perf-testing`. Project tarballs that can be used for testing can be found over on the [performance-data](https://gitlab.com/gitlab-org/quality/performance-data) project. A different project could be used if required.
|
|
|
|
There are several options for importing the project into your GitLab environment. They are detailed as follows with the assumption that the recommended group `qa-perf-testing` and project `gitlabhq` are being set up.
|
|
|
|
## Importing the project
|
|
|
|
There are several ways to import a project.
|
|
|
|
### Importing via UI
|
|
|
|
The first option is to simply [import the Project tarball file via the GitLab UI](../user/project/settings/import_export.md#importing-the-project):
|
|
|
|
1. Create the group `qa-perf-testing`
|
|
1. Import the [GitLab FOSS project tarball](https://gitlab.com/gitlab-org/quality/performance-data/-/blob/master/projects_export/gitlabhq_export.tar.gz) into the Group.
|
|
|
|
It should take up to 15 minutes for the project to fully import. You can head to the project's main page for the current status.
|
|
|
|
NOTE: **Note:**
|
|
This method ignores all the errors silently (including the ones related to `GITALY_DISABLE_REQUEST_LIMITS`) and is used by GitLab's users. For development and testing, check the other methods below.
|
|
|
|
### Importing via the `import-project` script
|
|
|
|
A convenient script, [`bin/import-project`](https://gitlab.com/gitlab-org/quality/performance/blob/master/bin/import-project), is provided with [performance](https://gitlab.com/gitlab-org/quality/performance) project to import the Project tarball into a GitLab environment via API from the terminal.
|
|
|
|
Note that to use the script, it will require some preparation if you haven't done so already:
|
|
|
|
1. First, set up [`Ruby`](https://www.ruby-lang.org/en/documentation/installation/) and [`Ruby Bundler`](https://bundler.io) if they aren't already available on the machine.
|
|
1. Next, install the required Ruby Gems via Bundler with `bundle install`.
|
|
|
|
For details how to use `bin/import-project`, run:
|
|
|
|
```shell
|
|
bin/import-project --help
|
|
```
|
|
|
|
The process should take up to 15 minutes for the project to import fully. The script will keep checking periodically for the status and exit once import has completed.
|
|
|
|
### Importing via GitHub
|
|
|
|
There is also an option to [import the project via GitHub](../user/project/import/github.md):
|
|
|
|
1. Create the group `qa-perf-testing`
|
|
1. Import the GitLab FOSS repository that's [mirrored on GitHub](https://github.com/gitlabhq/gitlabhq) into the group via the UI.
|
|
|
|
This method will take longer to import than the other methods and will depend on several factors. It's recommended to use the other methods.
|
|
|
|
### Importing via a Rake task
|
|
|
|
> The [Rake task](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/tasks/gitlab/import_export/import.rake) was [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/20724) in GitLab 12.6, replacing a GitLab.com Ruby script.
|
|
|
|
This script was introduced in GitLab 12.6 for importing large GitLab project exports.
|
|
|
|
As part of this script we also disable direct and background upload to avoid situations where a huge archive is being uploaded to GCS (while being inside a transaction, which can cause idle transaction timeouts).
|
|
|
|
We can simply run this script from the terminal:
|
|
|
|
Parameters:
|
|
|
|
| Attribute | Type | Required | Description |
|
|
| --------- | ---- | -------- | ----------- |
|
|
| `username` | string | yes | User name |
|
|
| `namespace_path` | string | yes | Namespace path |
|
|
| `project_path` | string | yes | Project name |
|
|
| `archive_path` | string | yes | Path to the exported project tarball you want to import |
|
|
|
|
```shell
|
|
bundle exec rake "gitlab:import_export:import[root, group/subgroup, testingprojectimport, /path/to/file.tar.gz]"
|
|
```
|
|
|
|
If you're running Omnibus, run the following Rake task:
|
|
|
|
```shell
|
|
gitlab-rake "gitlab:import_export:import[root, group/subgroup, testingprojectimport, /path/to/file.tar.gz]"
|
|
```
|
|
|
|
#### Troubleshooting
|
|
|
|
Check the common errors listed below, what they mean, and how to fix them.
|
|
|
|
##### `Exception: undefined method 'name' for nil:NilClass`
|
|
|
|
The `username` is not valid.
|
|
|
|
##### `Exception: undefined method 'full_path' for nil:NilClass`
|
|
|
|
The `namespace_path` does not exist.
|
|
For example, one of the groups or subgroups is mistyped or missing
|
|
or you've specified the project name in the path.
|
|
|
|
The task will only create the project.
|
|
If you want to import it to a new group or subgroup then create it first.
|
|
|
|
##### `Exception: No such file or directory @ rb_sysopen - (filename)`
|
|
|
|
The specified project export file in `archive_path` is missing.
|
|
|
|
##### `Exception: Permission denied @ rb_sysopen - (filename)`
|
|
|
|
The specified project export file can not be accessed by the `git` user.
|
|
|
|
Setting the file owner to `git:git`, changing the file permissions to `0400`, and moving it to a
|
|
public folder (for example `/tmp/`) fixes the issue.
|
|
|
|
##### `Name can contain only letters, digits, emojis ...`
|
|
|
|
```plaintext
|
|
Name can contain only letters, digits, emojis, '_', '.', dash, space. It must start with letter,
|
|
digit, emoji or '_'. and Path can contain only letters, digits, '_', '-' and '.'. Cannot start
|
|
with '-', end in '.git' or end in '.atom'
|
|
```
|
|
|
|
The project name specified in `project_path` is not valid for one of the specified reasons.
|
|
|
|
Only put the project name in `project_path`. If, for example, you put a path of subgroups in there
|
|
it will fail with this error as `/` is not a valid character in a project name.
|
|
|
|
##### `Name has already been taken and Path has already been taken`
|
|
|
|
A project with that name already exists.
|
|
|
|
### Importing via the Rails console
|
|
|
|
The last option is to import a project using a Rails console:
|
|
|
|
1. Start a Ruby on Rails console:
|
|
|
|
```shell
|
|
# Omnibus GitLab
|
|
gitlab-rails console
|
|
|
|
# For installations from source
|
|
sudo -u git -H bundle exec rails console -e production
|
|
```
|
|
|
|
1. Create a project and run `Project::TreeRestorer`:
|
|
|
|
```ruby
|
|
shared_class = Struct.new(:export_path) do
|
|
def error(message)
|
|
raise message
|
|
end
|
|
end
|
|
|
|
user = User.first
|
|
|
|
shared = shared_class.new(path)
|
|
|
|
project = Projects::CreateService.new(user, { name: name, namespace: user.namespace }).execute
|
|
begin
|
|
#Enable Request store
|
|
RequestStore.begin!
|
|
Gitlab::ImportExport::Project::TreeRestorer.new(user: user, shared: shared, project: project).restore
|
|
ensure
|
|
RequestStore.end!
|
|
RequestStore.clear!
|
|
end
|
|
```
|
|
|
|
1. In case you need the repository as well, you can restore it using:
|
|
|
|
```ruby
|
|
repo_path = File.join(shared.export_path, Gitlab::ImportExport.project_bundle_filename)
|
|
|
|
Gitlab::ImportExport::RepoRestorer.new(path_to_bundle: repo_path,
|
|
shared: shared,
|
|
project: project).restore
|
|
```
|
|
|
|
We are storing all import failures in the `import_failures` data table.
|
|
|
|
To make sure that the project import finished without any issues, check:
|
|
|
|
```ruby
|
|
project.import_failures.all
|
|
```
|
|
|
|
## Performance testing
|
|
|
|
For Performance testing, we should:
|
|
|
|
- Import a quite large project, [`gitlabhq`](https://gitlab.com/gitlab-org/quality/performance-data#gitlab-performance-test-framework-data) should be a good example.
|
|
- Measure the execution time of `Project::TreeRestorer`.
|
|
- Count the number of executed SQL queries during the restore.
|
|
- Observe the number of GC cycles happening.
|
|
|
|
You can use this snippet: `https://gitlab.com/gitlab-org/gitlab/snippets/1924954` (must be logged in), which will restore the project, and measure the execution time of `Project::TreeRestorer`, number of SQL queries and number of GC cycles happening.
|
|
|
|
You can execute the script from the `gdk/gitlab` directory like this:
|
|
|
|
```shell
|
|
bundle exec rails r /path_to_sript/script.rb project_name /path_to_extracted_project request_store_enabled
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
In this section we'll detail any known issues we've seen when trying to import a project and how to manage them.
|
|
|
|
### Gitaly calls error when importing
|
|
|
|
If you're attempting to import a large project into a development environment, you may see Gitaly throw an error about too many calls or invocations, for example:
|
|
|
|
```plaintext
|
|
Error importing repository into qa-perf-testing/gitlabhq - GitalyClient#call called 31 times from single request. Potential n+1?
|
|
```
|
|
|
|
This is due to a [n+1 calls limit being set for development setups](gitaly.md#toomanyinvocationserror-errors). You can work around this by setting `GITALY_DISABLE_REQUEST_LIMITS=1` as an environment variable, restarting your development environment and importing again.
|
|
|
|
## Access token setup
|
|
|
|
Many of the tests also require a GitLab Personal Access Token. This is due to numerous endpoints themselves requiring authentication.
|
|
|
|
[The official GitLab docs detail how to create this token](../user/profile/personal_access_tokens.md#creating-a-personal-access-token). The tests require that the token is generated by an admin user and that it has the `API` and `read_repository` permissions.
|
|
|
|
Details on how to use the Access Token with each type of test are found in their respective documentation.
