# Uploads sanitize Rake tasks **(FREE SELF)**
|
|
|
|
In GitLab 11.9 and later, EXIF data is automatically stripped from JPG or TIFF image uploads.
|
|
|
|
EXIF data may contain sensitive information (for example, GPS location), so you
|
|
can remove EXIF data from existing images that were uploaded to an earlier version of GitLab.
|
|
|
|
## Prerequisite
|
|
|
|
To run this Rake task, you need `exiftool` installed on your system. If you installed GitLab:
|
|
|
|
- Using the Omnibus package, you're all set.
|
|
- From source, make sure `exiftool` is installed:
|
|
|
|
```shell
|
|
# Debian/Ubuntu
|
|
sudo apt-get install libimage-exiftool-perl
|
|
|
|
# RHEL/CentOS
|
|
sudo yum install perl-Image-ExifTool
|
|
```
|
|
|
|
## Remove EXIF data from existing uploads
|
|
|
|
To remove EXIF data from existing uploads, run the following command:
|
|
|
|
```shell
|
|
sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:sanitize:remove_exif
|
|
```
|
|
|
|
By default, this command runs in "dry run" mode and doesn't remove EXIF data. It can be used for
|
|
checking if (and how many) images should be sanitized.
|
|
|
|
The Rake task accepts following parameters.
|
|
|
|
| Parameter | Type | Description |
|
|
|:-------------|:--------|:----------------------------------------------------------------------------------------------------------------------------|
|
|
| `start_id` | integer | Only uploads with equal or greater ID are processed |
|
|
| `stop_id` | integer | Only uploads with equal or smaller ID are processed |
|
|
| `dry_run` | boolean | Do not remove EXIF data, only check if EXIF data are present or not. Defaults to `true` |
|
|
| `sleep_time` | float | Pause for number of seconds after processing each image. Defaults to 0.3 seconds |
|
|
| `uploader` | string | Run sanitization only for uploads of the given uploader: `FileUploader`, `PersonalFileUploader`, or `NamespaceFileUploader` |
|
|
| `since` | date | Run sanitization only for uploads newer than given date. For example, `2019-05-01` |
|
|
|
|
If you have too many uploads, you can speed up sanitization by:
|
|
|
|
- Setting `sleep_time` to a lower value.
|
|
- Running multiple Rake tasks in parallel, each with a separate range of upload IDs (by setting
|
|
`start_id` and `stop_id`).
|
|
|
|
To remove EXIF data from all uploads, use:
|
|
|
|
```shell
|
|
sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:sanitize:remove_exif[,,false,] 2>&1 | tee exif.log
|
|
```
|
|
|
|
To remove EXIF data on uploads with an ID between 100 and 5000 and pause for 0.1 second after each file, use:
|
|
|
|
```shell
|
|
sudo RAILS_ENV=production -u git -H bundle exec rake gitlab:uploads:sanitize:remove_exif[100,5000,false,0.1] 2>&1 | tee exif.log
|
|
```
|
|
|
|
The output is written into an `exif.log` file because it is often long.
|
|
|
|
If sanitization fails for an upload, an error message should be in the output of the Rake task.
|
|
Typical reasons include that the file is missing in the storage or it's not a valid image.
|
|
|
|
[Report](https://gitlab.com/gitlab-org/gitlab/-/issues/new) any issues and use the prefix 'EXIF' in
|
|
the issue title with the error output and (if possible) the image.
