Downloads with the same suggested filename silently overwrite each other in the output dir #514
Description
Downloads are saved to <outputDir>/<suggestedFilename>. Unlike screenshots, snapshots and storage-state files, which get timestamped names, a second download with the same suggested name replaces the first. Both responses report the same path, so the first file is lost without any warning. Sites commonly reuse names such as invoice.pdf, export.csv or report.xlsx.
Steps to reproduce
<!-- dl.html -->
<a href="data:text/plain,v1" download="same.txt">V1</a>
<a href="data:text/plain,v2" download="same.txt">V2</a>playwright-cli open http://127.0.0.1:8765/dl.html
playwright-cli click 'text=V1' # Downloaded file same.txt to ".playwright-cli/same.txt"
playwright-cli click 'text=V2' # Downloaded file same.txt to ".playwright-cli/same.txt"
cat .playwright-cli/same.txt # v2Expected
The second download gets a unique name (for example same-1.txt, the way video files get a -1 suffix), and the event reports that path.

Hi, I'm the Playwright bot and I reproduced this on Linux with Chrome at upstream
main(1.66.0-next,edeb0bd05176ff187c372c1e38e5d89a232bd5b3).Reproduced. The download handler passes the suggested path directly to
saveAs(), which overwrites an existing file. The proposed fix reserves a free path before saving and adds-1,-2, etc. before the extension on collision. The completion event reports that path.Repro and verification
The regression test serves two links with
download="same.txt"and different contents, then clicks them withplaywright-cli click text=V1andplaywright-cli click text=V2. It checks that the events reportsame.txtandsame-1.txt, and that both files retain their respective contents.Before the fix, Chrome reports
same.txtfor both downloads and the test fails. With the fix, the regression passes on Chrome, Chromium, Firefox and WebKit in headless mode on Linux. The CLI save-as and shared file-handling suites pass: 81 passed, 7 existing browser-specific skips. The upstream build andnpm run flintalso pass.Draft PR: microsoft/playwright#43930
