BuildZipDownloadJob walks the loose file ids and then every selected
folder's subtree, and adds whatever each pass finds. A selection can
reach the same file from more than one of them, and nothing noticed:
file_ids [f], folder_ids [Reports]
-> ['report.pdf', 'Reports/report.pdf']
file_ids [f], folder_ids [Reports, Reports/Q1]
-> three entries, file_count 3, total_size three times the file
Two copies of the same bytes in one archive, and total_size is what the
size cap is checked against, so a selection could also be refused for a
weight it does not have.
The one that costs more than bandwidth is delivery. It logs one
FileDownloaded per contained file, and DownloadAllowance counts those
records -- so a file limited to a single download left in three copies
while the log recorded one. Measured: three entries, one record.
Two causes, so two halves.
`$added` is now keyed by id instead of being appended to a list, and the
folder pass skips a file already in the archive. A lookup rather than a
scan because the selection cap is 10000 sources. The loose pass runs
first, so a file picked both ways sits under its loose name; either
answer is defensible, but it has to be the same one every run.
And a selected folder inside another selected folder is dropped before
either is walked. Zipping both would reach every file in the inner one
twice, and which path the surviving entry ended up under would be decided
by the order the rows came back in. Keeping the outer folder keeps the
fuller path -- Reports/Q1/report.pdf rather than Q1/report.pdf.
Containment is decided on the materialized path, so it is one comparison
per pair with no queries: a folder's path starts with an ancestor's
subtreePathPrefix(), and both end in '/', so /5/ cannot match /50/.
Not changed: the per-file re-checks inside the folder pass. Visibility
and the download allowance are still re-derived per file, and the skip
happens before them, so a duplicate never spends an allowance twice
either. Nor the selection endpoint -- a caller may send whatever
selection they like, and the job is where it is resolved.
Four tests. Three measured red against the unfixed job (3 failed / 32
passed): the loose-plus-folder case, the nested-folder case, and the
three-way case asserted through delivery rather than through the archive.
The fourth -- two selected folders that merely share a name are both
zipped -- is green either way and guards the pruning against being about
names rather than containment.
Full suite passes (2052 passed / 2 skipped), PHPStan level 8 clean.
ProjectSend
Share files with your clients, from your own server.
ProjectSend is a self-hosted application for getting files to the people you work with. You upload what you want to send, choose exactly who can see it, and each client signs in to their own private page to download it.
No public link passed around by email, no third-party service holding your clients' documents, no per-seat pricing. It runs on your server, and the files stay there.
What it does
For the people you send to
- A private area per client, showing only what has been shared with them
- Sign in with an email address, with optional two-factor authentication
- Search, filter and sort their files; download one, several as a zip, or a whole folder
- Optional comments on a file, so questions live next to the thing they are about
- Email notifications when something new arrives, in their own language
For you
- Resumable uploads that survive a dropped connection, so large files actually arrive
- Organise with folders, categories and client groups
- Share with one client, a whole group, or publicly — and set an expiry date or a download limit
- Thumbnails and previews for images and documents
- Storage quotas per client, and custom fields for the details you need to keep on them
- A full activity log and download history: who got what, and when
For the installation
- Roles and permissions for your own team, so an uploader is not an administrator
- Sign-in the way you already work: LDAP, social sign-in, or plain email and password
- Themes for the client-facing pages and for outgoing email
- 16 languages
- A REST API with scoped tokens and generated OpenAPI docs
- Privacy controls, including GDPR-grade account erasure with a grace period
- Local disk, S3-compatible storage, or Google Cloud Storage
Screenshots
The dashboard — what is in the installation, and what has been happening in it.
Your library — folders, categories, and who each file is shared with.
What your client sees — only their files, nothing else.
Getting started
With Docker — the quickest path, and the one we recommend. Nothing to build: the published image ships with its dependencies and its frontend already compiled.
curl -O https://raw.githubusercontent.com/projectsend/projectsend/main/docker/production/compose.example.yaml
# edit the passwords and APP_URL in it, then:
docker compose -f compose.example.yaml up -d
Open APP_URL and the first thing you see is a setup screen that creates your administrator
account — or uncomment ADMIN_EMAIL and ADMIN_PASSWORD in the file first, with a password of
your own, and it is created for you.
Before you put real files in it, read DOCKER.md — where your database and uploads actually live, how to move them onto paths you chose, and how to back them up so an upgrade can't take them with it.
Without Docker — for servers where it isn't an option, install from a release zip.
INSTALL.md covers requirements, .env, nginx, the background worker and cron,
updating and troubleshooting. You do not need Composer or npm on the server; the zip ships ready to
run.
Already running it? UPDATE.md is how you move to a new version — one command on Docker, one script on your own server, and what to check afterwards either way.
Want to work on ProjectSend itself? Cloning the repository gets you a development copy, not an installation: the dependencies and the compiled frontend are deliberately not in git, so a clone needs Composer and npm before it runs. CONTRIBUTING.md has the sequence, and it is short.
Coming from ProjectSend Legacy?
The previous generation of ProjectSend lives on at projectsend/legacy. This is a rebuild rather than an upgrade, so moving across is an import rather than an update — install fresh, then bring your old site into it with the migration tool: accounts, clients, groups, categories, folders, files and history.
It never writes to your old install, and any run can be undone with a single command. MIGRATING-FROM-V1.md explains what comes across, the two routes (same machine, or a portable export from a server you can't reach), and the one change your clients will notice: they sign in with their email address now, using the same password.
