"Content-Disposition: attachment"
Summary:
We currently serve some files off the primary domain (with "Content-Disposition:
attachment" + a CSRF check) and some files off the alternate domain (without
either).
This is not sufficient, because some UAs (like the iPad) ignore
"Content-Disposition: attachment". So there's an attack that goes like this:
- Alice uploads xss.html
- Alice says to Bob "hey download this file on your iPad"
- Bob clicks "Download" on Phabricator on his iPad, gets XSS'd.
NOTE: This removes the CSRF check for downloading files. The check is nice to
have but only raises the barrier to entry slightly. Between iPad / sniffing /
flash bytecode attacks, single-domain installs are simply insecure. We could
restore the check at some point in conjunction with a derived authentication
cookie (i.e., a mini-session-token which is only useful for downloading files),
but that's a lot of complexity to drop all at once.
(Because files are now authenticated only by knowing the PHID and secret key,
this also fixes the "no profile pictures in public feed while logged out"
issue.)

usefully-named file
Summary:
If you Command-L + Option-Return to download stuff off, e.g., Paste,
you get "PHID-FILE-ad98abg9bsd9ashbs.txt" in your download folder. Put the file
name in the URI instead, so you get a reasonably named file.
Test Plan: Downloaded some files, got reasonable results.

Summary:
See T549. Under configurations where files are served from an alternate domain
which does not have cookie credentials, we use random keys to prevent browsing,
similar to how Facebook relies on pseudorandom information in image URIs (we
could some day go farther than this and generate file sessions on the alternate
domain or something, I guess).
Currently, we generate these random keys in a roundabout manner. Instead, use a
real entropy source and store the key on the object. This reduces the number of
sha1() calls in the codebase as per T547.
Test Plan: Ran upgrade scripts, verified database was populated correctly.
Configured alternate file domain, uploaded file, verified secret generated and
worked properly. Changed secret, was given 404.

domain
Summary:
See D758, D759.
- Provide a strongly recommended setting which permits configuration of an
alternate domain.
- Lock cookies down better: set them on the exact domain, and use SSL-only if
the configuration is HTTPS.
- Prevent Phabriator from setting cookies on other domains.
This assumes D759 will land, it is not effective without that change.
Test Plan:
- Attempted to login from a different domain and was rejected.
- Logged out, logged back in normally.
- Put install in setup mode and verified it revealed a warning.
- Configured an alterate domain.
- Tried to view an image with an old URI, got a 400.
- Went to /files/ and verified links rendered to the alternate domain.
- Viewed an alternate domain file.
- Tried to view an alternate domain file without the secret key, got a 404.

Summary:
See T344. Currently, there's a hard-coded 12MB filesize limit and some awkward
interactions with MySQL's max_allowed_packet. Make this system generally more
robust:
- Move the upload limit to configuration.
- Add setup steps which reconcile max_allowed_packet vs MySQL file storage
limits.
- Add a layer of indirection between uploading files and storage engines.
- Allow the definition of new storage engines.
- Define a local disk storage engine.
- Add a "storage engine selector" class which manages choosing which storage
engines to put files in.
- Document storage engines.
- Document file storage classes.
Test Plan:
Setup mode:
- Disabled MySQL storage engine, misconfigured it, configured it correctly.
- Disabled file storage engine, set it to something invalid, set it to
something valid.
- Verified max_allowed_packet is read correctly.
Application mode:
- Configured local file storage.
- Uploaded large and small files.
- Verified larger files were written to local storage.
- Verified smaller files were written to MySQL blob storage.
Documentation:
- Read documentation.

Summary:
- have files be uploaded by drag+drop instead of browse.
- Files are named by their uploaded filename, the user isn't given a chance to enter a file name. Is this bad?
- Store author PHID now with files
- Allow an ?author=<username> to limit the /files/ list by author.
- If one file is uploaded, the user is taken to its info page.
- If several are uploaded, they are taken to a list of their files.
Test Plan:
- Quickly tested everything and it still worked, I'd recommend some people try this out before it gets committed though. It's a rather huge revision.

Make 'gd' an explicit optional dependency, test for it in setup, and make the
software behave correctly if it is not available.
When generating file thumnails, provide reasonable defaults and behavior for
non-image files.
Test Plan:
Uploaded text files, pdf files, etc., and got real thumbnails instead of a
broken image.
Simulated setup and gd failures and walked through setup process and image
fallback for thumbnails.

Summary:
Previously, Remarkup allowed you to paste in an image URI and get an inline
image. However, it did this by hotlinking the image which isn't so hot in an
open source product.
Restore this feature, but use image proxying instead. The existing image macro
code does most of the work.
There is a mild security risk depending on the network setup so I've left this
default-disabled and made a note about it. It should be safe to enable for
Facebook.
Test Plan:
Pasted in image and non-image links, got reasonable behavior. Verified proxying
appears to work. Verified that file:// shenanigans produce 400.
