Run the automatic update in two requests and say why it failed (#450, 0.7.92) - #452
Conversation
…stream the package to disk
- A fatal error during an update answers JSON with PHP's message (answerJsonOnFatal on download, install-manual and perform); a non-JSON answer is shown with its HTTP status and the start of its text (readUpdateJson, shared by the automatic, manual and token requests), which also send Accept: application/json so a CSRF or session failure is JSON. - The progress lists the steps in the order they now run: download, backup, files, migrations. - New strings in the five locales; updater-hardening asserts the token scoping on the streaming download. - Tests: updater-fatal-json.unit.php (a real memory fatal in a child PHP answers JSON) and updater-two-step-450.spec.js. tests/auto-upgrade-real.spec.js stays local, next to manual-upgrade-real. - version.json 0.7.92, changelog and README.

Important
A download that times out partway through is reported as a failed sha256 check. The cURL error is dropped. So on the slow hosting #450 is about, the operator still isn't told why the update failed.
Reviewed changes
I reviewed the full PR: the automatic update now runs as download and then install-manual, the package is streamed to disk, and failures now come back as JSON with a readable message.
- Two-request automatic update. The new
POST /admin/updates/downloadcallsUpdater::downloadPackageForInstall(), which saves a verified package understorage/tmp/manual_update_*and puts its path in the session. The page then calls the existinginstall-manualrequest. - Streaming download.
downloadUpdate()is split intoreleasePackageAsset(),fetchVerifiedPackage()andstreamToFile(). The package goes to a.partfile, is hashed withhash_file, and is renamed only once the hash matches. - Errors come back as JSON.
answerJsonOnFatal()turns a PHP fatal into a JSON 500.readUpdateJson()shows the HTTP status and the start of the text when the answer is not JSON. The update requests now sendAccept: application/json. - Progress order and tests. The progress now lists download before backup. There is a new pure unit test for the fatal guard (it passes locally, and so does
updater-hardening.unit.php) and a Playwright spec.

…aned update packages A cURL transfer that broke off after the headers (a timeout on a slow link) returned 200, and the partial file failed the sha256 check, so the operator read a checksum mismatch. It now fails with the transport's reason, and a PHP stream copy that times out does the same. manual_update_* folders whose install never ran are swept after an hour with the other temporary update folders.

ℹ️ No blocking issues. Both earlier findings are fixed. One small gap is left in the download path used when cURL is missing.

This review covers commit a5253829, pushed after the previous Pullfrog review at 44ae6e5.
- A cut-off download is reported as a download failure. When cURL fails after the server has answered,
streamToFile()now throwsDownload fallito: <curl_error>. The PHP-stream fallback throwsDownload fallito: trasferimento interrottowhen a 2xx copy fails or times out. The new string is translated in all five locales. - Old update packages are cleaned up.
cleanupOldTempDirs()now goes throughpinakes_update_*,pinakes_app_backup_*andmanual_update_*in a single loop, with the same one-hour limit. The page callsinstall-manualstraight after the upload or download, so a package that was just fetched is not at risk. - New test for a cut-off download.
tests/updater-truncated-download.unit.phpstarts a local server that sends 5000 of the 100000 bytes it announces. The test passes locally (transfer closed with 95000 bytes remaining to read), andupdater-hardening.unit.phpstill passes.

…again before installing it A download and an upload in two tabs shared one waiting package in the session, and the install request took whichever came last. Both now answer with an opaque package id that the install request sends back; a replaced package is refused with 409 and left for its own request, and the one it replaced is deleted. A downloaded package is checked against its sha256 again before the install, and the storage/tmp prefix check now requires a path separator.

ℹ️ No new issues in this commit. The only thing still open is the earlier thread on
Updater.php:1626, about the download path used when cURL is missing. This commit doesn't change that code.

- Each pending package gets its own id. Uploads and downloads now both go through
holdPendingPackage(). It deletes the package that was waiting before (viadiscardPendingPackage(), which only removes amanual_update_*folder directly understorage/tmp), stores a random id in the session and returns that id to the page. The page sends the id back toinstall-manual. install-manualrefuses a package that was replaced. If the id doesn't match, the request gets a 409 and the session is left as it was, so the other tab can still install its own package. Thestorage/tmpprefix check now requires a trailing separator.- The download is hashed again before install. A downloaded package is checked against its sha256 a second time just before
performUpdateFromFile(). If it no longer matches, the request gets a 400 with the existing checksum message. Uploads skip this check. - New pure test.
tests/update-pending-package.unit.phpreplacesUpdaterwith a recorder and callsinstallManualUpdate()directly. I ran it locally and all 12 checks pass. Its assertions would fail if the id check or the re-hash were removed.updater-hardening,updater-fatal-jsonandupdater-truncated-downloadstill pass too. The app uses PHP's default file sessions, which lock, so two tabs' requests run one after the other. That means a package can't be deleted while another request is installing it.

- Around line 1622-1629: Update the PHP-stream download fallback around
`stream_copy_to_stream()` to detect truncated bodies when the server closes the
connection early. Read `Content-Length` from the final response block in
`$meta['wrapper_data']`, and treat a successful 2xx transfer as interrupted when
`$copied` is less than that length, alongside the existing failure and timeout
checks.

Without cURL the updater copies a PHP stream, and a server that closes the connection early ends the copy with fewer bytes, not with an error. The fallback is now its own method, compares the bytes copied with the Content-Length of the final response block, and reports a short body as a broken-off download. The truncated-download test runs both paths.

✅ No new issues found. This commit fixes the last open finding: without cURL, a download cut short by the server closing the connection is now reported as a failed download, not as a checksum mismatch.
Reviewed changes
This review covers commit 2fc67fb4, pushed after the previous Pullfrog review at ac08fdf.
- Moved the PHP-stream fallback into its own method.
streamToFile()now hands off tostreamWithPhp(). On a 2xx response, that method treats the download as interrupted if fewer bytes arrived than theContent-Lengthof the final response block. It reads only the final block because it resets at eachHTTP/status line, so a redirect's own headers are ignored. The existing checks for a failed copy and a timeout are unchanged. - Ran the truncation test against both download paths.
tests/updater-truncated-download.unit.phppoints the truncating local server atstreamToFile()(cURL) and atstreamWithPhp()(through reflection). I ran it locally and all 12 checks pass, underphpand underphp -n. The PHP-stream case reportsDownload fallito: trasferimento interrotto.updater-hardeningandupdate-pending-packagealso still pass.

Fixes #450. The automatic update failed on some hosting with "The server returned an invalid response", while uploading the same package by hand worked.
Why
The automatic update did everything in one request (
/admin/updates/perform):On hosting that cuts long requests off behind a proxy, or will not raise PHP's memory limit, that request ended with an error page instead of JSON. The page could only say "invalid response". A manual update was already split in two (upload, then
install-manual). Locally the single request finishes in about 11 s, so the difference is environmental, and the fix removes the environmental risk instead of guessing which limit it hit.What changes
POST /admin/updates/download(new): the server downloads the release, verifies its sha256 against the GitHub API digest and keeps it understorage/tmp, with the path in the session as for an upload;install-manual: the same request a manual update ends with, which runs the same steps as/perform(preflight, pre-update patch, backup, install, post-install patch).CURLOPT_FILE, a PHP stream as fallback) and hashed withhash_file, so it is never held in memory. This also applies to the single-request/perform, which stays for API callers. Asset selection and verified fetch are shared (releasePackageAsset,fetchVerifiedPackage,streamToFile).Accept: application/json, so a CSRF or session failure is JSON too.An installation older than 0.7.92 still updates with its own updater. If it fails there, the 0.7.92 package has to be uploaded once by hand.
Tests
tests/updater-fatal-json.unit.php: a child PHP registers the guard and exhausts its memory, and the answer is JSON naming the memory error.tests/updater-two-step-450.spec.jschecks, on the real updates page:tests/updater-hardening.unit.phpnow asserts the token scoping on the streaming download.I also ran the full automatic update against GitHub with the reinstall harness, in two cases:
Both succeeded and the schema was verified.
