ignacionelson 7ff2674e4f Merge pull request #1725 from denkfabrik-li/fix/rendition-written-atomically
Both thumbnail routes treat "the file exists" as "the rendition is cached", and nothing ever invalidates one: RenderedImageCache::flush() runs on ImageRenderingChanged, which no code in core raises. Whatever sits at the path is what every later viewer gets. ThumbnailGenerator::generate() encoded straight onto that path, so a render that died partway -- a full volume, a killed worker -- left a half-written file that was then served as the rendition indefinitely, and two requests rendering the same file at once encoded into the same path together.

Write side: the image is written beside its destination and renamed into place. rename() within a directory is atomic and replaces what is there, so the path holds either the previous rendition or a complete new one, and the loser of a race leaves a whole image rather than a mixture of two. Renditions always cache on the local files disk and the generator is handed $disk->path(), so both files are on the same filesystem and the atomicity is real. Read side: an empty file is not a rendition, so both routes replace one rather than serve it -- writing through a temporary file means core can no longer create that state, but an installation that ran an older version can already have it on disk and nothing else will ever clear it.

The cache itself is unchanged: a non-empty rendition is still reused without further checks, because decoding every cached image on every request to prove it is intact would cost the cache its point. The RenderingImage seam still fires before the encode.

Verified before merging: 14 passed on the trial-merge, 2 failed / 12 passed with app/ reset. The third test, about the generator's own temporary file, passes either way and the PR says so rather than leaving it to be found.

Reported and fixed by @denkfabrik-li.

ProjectSend

Share files with your clients, from your own server.

License: GPL v2 or later PHP 8.4+ Self-hosted


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

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.

Contributing

Bug reports, translations and pull requests are all welcome — see CONTRIBUTING.md for how to set up a development copy, what the checks are, and the contributor agreement.
