Allow uploading .zip, .rar, and .7z files from disk. The archive will be extracted and the images
inside will be uploaded.
This only works for archive files uploaded from disk, not from a source URL.
Post source URLs will look something like this: "file://foo.zip/1.jpg", "file://foo.zip/2.jpg", etc.
Sometimes artists uses Shift JIS or other encodings instead of UTF-8 for filenames. In these cases
we just assume the filename is UTF-8 and replace invalid characters with '?', so filenames might be
wrong in some cases.
There are various protections to prevent uploading malicious archive files:
* Archives with more than 100 files aren't allowed.
* Archives that decompress to more than 100MB aren't allowed.
* Archives with filenames containing '..' components aren't allowed (e.g. '../../../../../etc/passwd').
* Archives with filenames containing absolute paths aren't allowed (e.g. '/etc/passwd').
* Archives containing symlinks aren't allowed (e.g. 'foo -> /etc/passwd').
* Archive types other than .zip, .rar, and .7z aren't allowed (e.g. .tar.gz, .cpio).
* File permissions, owners, and other metadata are ignored.
Partial fix for #5340: Add support for extracting archive attachments from certain sources
Fix /posts/random?tags=touhou to redirect to /posts/1234?q=touhou instead of /posts/1234?tags=touhou.
Fixes the search bar on random posts not containing the current search.
Fix temp files generated during the upload process not being cleaned up quickly enough. This included
downloaded files, generated preview images, and Ugoira video conversions.
Before we relied on `Tempfile` cleaning up files automatically. But this only happened when the
Tempfile object was garbage collected, which could take a long time. In the meantime we could have
hundreds of megabytes of temp files hanging around.
The fix is to explicitly close temp files when we're done with them. But the standard `Tempfile`
class doesn't immediately delete the file when it's closed. So we also have to introduce a
Danbooru::Tempfile wrapper that deletes the tempfile as soon as it's closed.
The `pry` gem was removed in e698bf91 because we replaced `pry-byebug` with the standard debugger.
Add it back because `pry` is better than `irb` and we still can use the standard debugger with it.
* Call it "Changes" when referring to the global list of changes (pool changes, artist changes, etc).
* Call it "History" when referring to the history of a single item (pool history, artist history, etc).
* Put the artist history search form on the /artist_versions page, and remove the /artist_versions/search endpoint.
Fix external HTTP requests not working when the HTTP proxy was enabled. Caused by the `public_only`
option (which prevents SSRF attacks by validating that the URL doesn't resolve to a local IP) being
incompatible with the `proxy` option.
Don't log a mod action when a user deletes their own account. This isn't a moderator action, so it
doesn't belong here. Account deletions are still logged on the /user_events page (visible to mods only).
A mod action is still logged when the Owner-level user deletes someone else's account.
Add media_asset_id and old_media_asset_id columns for associating replacements with media assets.
This way we can easily tell which replacements don't have a media asset (with the md5 alone we can't
tell whether the media asset actually exists).
Add a fix script to download images from Gelbooru for old replacements where we deleted the original
image. For archival purposes, we want to try to find the original file for every replacement.
These images will be uploaded as unposted assets under DanbooruBot's name.
Add a fix script that imports the md5 for old post replacements from the corresponding DanbooruBot
replacement comment, then deletes all replacement comments.
There are about 250 replacements left that still have a null md5 because they don't have a matching
comment. This is because if a post was replaced but the file didn't change, it didn't leave a comment.
