Client file sharing, rebuilt from the ground up: a private area per client, resumable uploads, folders, groups and categories, sharing with expiry dates and download limits, comments, file versions, an activity log, a REST API, and sixteen languages. This repository begins here. ProjectSend 2 was developed privately, and that development history is not published — the previous generation remains available, with its own history, at projectsend/legacy. Free software under the GNU General Public License v2, or (at your option) any later version.

/**
|
|
* FilePolicy::view() expressed as a query instead of a per-model check —
|
|
* the same rules, evaluated in SQL so a caller can ask "every file this
|
|
* user may see" without loading candidates first.
|
|
*
|
|
* This exists because a folder is not a bag of uniformly-visible files: a
|
|
* user may hold a folder while individual files inside it are not theirs
|
|
* to read (a client's expired file is the live case — see
|
|
* File::scopeVisibleToClient, which ends in notExpired()). Anything that
|
|
* expands a folder into its contents must therefore re-derive visibility
|
|
* per file rather than inherit it from the folder, or the folder becomes a
|
|
* way around the per-file rule. BuildZipDownloadJob is the first such
|
|
* caller; any future bulk operation over a subtree is the next.
|
|
*
|
|
* Keep this in lockstep with FilePolicy::view(). The policy stays the
|
|
* authority for a single known file; this is its set-shaped twin.
