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.
Reproduced on current upstream (
1.66.0-next,489470e3bbf48a50bd8f4a59401d50cb531b5902) on Linux with Chrome, Chromium, Firefox and WebKit. Downloads reuse the site's suggested name, andsaveAs()replaces the earlier file. The proposed fix adds opt-in ordinal naming tooutputFile, as requested in the review of microsoft/playwright#43930: the first download keepssame.txt, and the next usessame-1.txt. Explicit user-supplied output filenames are unchanged.Reproduction and verification
The CLI test serves two links with
download="same.txt", pointing to text responses containingv1andv2. It opens the page, clicks each link, checks the reported destination, and reads both saved files.Without the fix, the second download reports
.playwright-cli/same.txtinstead of.playwright-cli/same-1.txton all four browsers. With the fix, the destinations differ and both contents are preserved.All runs were headless on Linux. The CLI save-as and shared file suites passed on Chrome, Chromium, Firefox and WebKit: 81 passed, 7 existing skips.
