fix(backup): rotate the legacy directory backups too, and stop warning about a normal state - #424
Merged
Conversation
…g about a normal state Both found by reading the logs of two production installs on shared hosting, after clearing 17 MB of accumulated artifacts by hand. The rotation added in 0.7.83 only ever globbed backup_*.zip. Before that layout existed an update left a directory holding a single database.sql, and listBackups() still surfaces those as backups — contents: 'db' — so an operator sees them in the same list. Nothing pruned them. One install had 33 of them and another 27, together 17 MB spanning December 2025 to June 2026, on an account sitting at 98% of its quota. They are now rotation candidates in one shared pool with the archives, because the list the operator reads is one list sorted by date: rotating the two formats separately would let a recent entry vanish while an older one survived. The same discipline as before applies — only the exact generated shape is a candidate, so a directory parked there by hand is never touched. deleteDirectory() now reports whether the directory is gone, and the rotation counts on that return value. Re-checking the path afterwards was the obvious alternative and PHPStan rejected it correctly: it had already narrowed the value to "a directory" and cannot see a filesystem side effect. Making the helper report its own outcome is the honest fix rather than an assertion the analyser has to be told to ignore. ApiBookScraper logged at WARNING that it was not enabled or not configured — which is the normal state of every plugin an operator has not set up. The path is reached on a schedule, so over eight months it produced 8.217 of the 15.607 lines in one app.log: more than half the file, for a condition that is not a problem. It drops to debug. The genuinely abnormal branch above it, missing DB or plugin ID, keeps its warning. A level that fires continuously teaches the reader to skip it, which is how the real ones get missed. Verified: backup-retention suite 18 passed / 0 failed with two new sections covering the legacy format and the hand-placed-directory exemption, PHPStan level 5 clean, php -l clean. The three failures in the full standalone run are the suites that refuse to touch a non-dedicated database, unrelated to this change.

The "Crea Backup Manuale" button and the automatic pre-update copy went through the same createBackup() and produced indistinguishable filenames. So a restore point someone created on purpose — usually right before doing something risky — was evicted as soon as ten automatic backups piled up behind it. Worse, pressing the button also triggered the rotation, so making a backup could delete backups. A backup the operator asked for is not interchangeable with one the system took on its own. It exists because someone decided, at that moment, that this state was worth keeping. Letting a rolling window consume it is not what the button promises. The same holds more strongly for the copy taken before a restore: that one IS the undo for the restore, and it was equally exposed. createBackup() now takes an origin. Automatic keeps the filename shape it already had, byte for byte, so every archive already on disk is still recognised and still rotated. Manual and safety copies get an origin suffix, which puts them outside GENERATED_NAME_PATTERN — the rule that was already excluding hand-placed archives. No second exclusion rule to keep in sync, and the rotation stays a decision it can make from a glob. The origin lives in the filename rather than only in the manifest for exactly that reason: the rotation would otherwise have to open every archive to decide what to delete. Preserved backups do not consume rotation slots either. The retention count means "keep this many automatic copies"; a hoard of manual ones must not starve that window. listBackups() reports the origin, reading the manifest first and falling back to the filename — archives written before origins existed carry neither and read as automatic, which is what they were. The suffix is stripped from the date shown to the operator. Verified: backup-retention suite 26 passed / 0 failed with two new sections, one asserting that manual and safety copies survive a rotation that drops nine automatic archives, one covering the origin round trip through the list. PHPStan level 5 clean. Exercised end to end against the real class: a manual and an automatic backup created, listed with the right origins and clean date labels, then deleted.
…he real UI
The unit suite proves the rules against the class. It cannot prove the operator actually gets them — that the button really produces a preserved backup, that the list really shows it, that download and delete really work on the folder format, that a rotation triggered from the page really spares what it must. Five browser tests, run serially against a real install.
1. The button produces a backup whose NAME carries the manual origin, and the row appears in the table. The name matters more than the manifest here: the rotation decides from a glob and never opens the archive.
2. Twelve automatic archives are planted older than anything real on the install, plus a manual and a safety copy made older still — so if origins ever stopped being honoured those two would be the first to go. A backup is then created from the button, which triggers the rotation. Both deliberate restore points survive; the automatic ones are trimmed.
3. A backup downloads from the list with the name it has on disk, and the response actually has a body.
4. A legacy directory lists, downloads as the raw .sql it contains, and offers no restore button — restoring a folder would have nothing to unpack.
5. Deleting works on both formats, and the legacy directory goes away with its contents. A delete that left database.sql behind would keep consuming the quota it was meant to release.
Writing them surfaced why they were needed: the first run failed because every destructive action on that page confirms through SweetAlert, which is DOM and not a native dialog, so page.on('dialog') never sees it and the request under test is never sent. A helper clicks .swal2-confirm, matching what the rest of the suite already does.
The spec plants nothing it cannot identify: every artefact carries a run id, and teardown removes both the planted files and whatever the button created. Verified by diffing storage/backups before and after — byte-identical, including a hand-placed `dewey` directory and an `uploaded_*.zip` archive that were sitting there already and that two rotations during the run left untouched. That is the hand-placed exemption demonstrated outside a fixture.
5 passed in 20s. backup-retention unit suite still 26/0, PHPStan level 5 clean, Playwright policy accepts the new file (162 total, 151 deep).
… teardown back at the end Two review findings, both valid against the code as it stood. A directory matching `update_YYYY-MM-DD_HHMMSS` was a rotation candidate on its name alone. A generated legacy backup IS its database.sql — that is the entire content of the format — so a directory carrying the name without the dump is something else wearing our shape, and this rotation deletes recursively. The name pattern was chosen precisely to reclaim only what we can show we wrote; requiring the dump completes that argument, and costs one stat() per candidate. Section I asserts it with an impostor directory made older than everything else, so it would be the first to go if it were ever eligible again, and checks its contents are still there afterwards. The second finding is mine to own. `$cleanup()` was the last statement of this file, and I appended sections E through H after it. So the teardown ran in the middle: it deleted the temp directory the new sections then recreated by accident, and — the part that matters — it restored the SHARED system_settings.retention_count before three more sections overwrote it. Every run left the setting at whatever the last section had set, for the app and for any suite that ran next. It is moved to the end, where it belongs. That had already happened on this working copy: the row was sitting at 3 with today's timestamp, written by a run of this very file. Since the app falls back to DEFAULT_RETENTION when the row is absent, the row was removed rather than guessed at — the state as if the broken run had never happened. Verified: 28 passed / 0 failed, PHPStan level 5 clean, and the five browser tests still pass in 19.4s. Both kinds of residue checked explicitly after a full run — storage/backups byte-identical to before, and zero retention_count rows, so the suite is now neutral on the shared database it borrows.

…st branch from disappearing in silence Two review findings, both about being able to trust what is written rather than about behaviour. The comment above the origin ternary in listBackups() said "manifest first, filename as the fallback", which stopped being true when the upload case was special-cased: for uploads the NAME wins, and it has to. An uploaded archive carries the manifest of another installation, which would claim origin auto and hand a restore point straight to the rotation. That reasoning is the whole justification for the branch, and it was nowhere in the file — the comment said the opposite, which is exactly the sort of comment the next reader uses to "simplify" the ternary away. The second is the mode-bit branch of the deletion test. It runs only when the operating system actually enforces the bits, so under root it contributed nothing and said nothing: the suite passed with two fewer assertions and no way to tell from the output. The requirement itself is not at risk there — the injected unlink() failure above covers it whatever the uid, which is what its label already claims — so the honest thing is a note, not a failed assertion. CodeRabbit proposed asserting the fixture is non-writable; that would turn a legitimate environment into a red suite while the requirement is already proven, so I did not take it. The note is indented by two spaces on purpose. ci-run-unit-tests.sh matches SKIP: at column 0 and under CI_STRICT_TESTS=1 a skip is a failure by design, and this is not a skipped requirement. Verified both ways: 12 passed / 0 failed as a normal user, and 10 passed / 0 failed plus the note with is_writable forced false, so the root path was executed rather than reasoned about. Alongside: PHPStan level 5 clean, backup-retention 37 / 0, the five browser tests green in 17.6s, storage/backups byte-identical afterwards and zero retention_count rows.

…ns of mine Ten findings, each checked against the code before being touched. Nine are fixed; the tenth — loading every issue into the association form — is real but needs a per-masthead lookup, and stays out as feature work, as the previous commit already said. Two were mine. The previous commit gated the masthead list behind "can this page show the association form", but the same list feeds the masthead FILTER on both tabs: on the index tab it emptied, and filtering to a masthead with no articles emptied the list and the dropdown with it, leaving the operator with no way back. The issue list is still gated; the masthead list is not. And the mastheads-list filter form and reset link still posted to the bare path, which Simple mode bounces to the articles list — I had named that defect in my own review and then only moved the workflow chooser in the same file. The filter form now carries view=titles as a hidden field rather than in its action: a GET form replaces the action's query string with its own fields, so a parameter put there is dropped on the first submit. Pagination already kept it. The mobile article list answered 200 with "private, no-store" beside an ETag, while every other bridge endpoint and this endpoint's own 304 send "private, max-age=0, must-revalidate". no-store forbids the client from keeping the body, so it can never send If-None-Match and the 304 branch was dead code. must-revalidate still forces a round trip every time, so an article the operator hides is never served from a stale copy. This is not the same question as the web article page, which keeps no-store: there is no ETag contract there, and the copy that matters is the edge cache's. The same handler now degrades like the web pages when emeroteca_contributi is missing — empty list, 404 for a detail — instead of reaching rows(), which throws. Two landed on #424's code, which this branch carries. A legacy backup directory counted as one if it held a database.sql; it is now one only if that is its sole entry, because the rotation deletes recursively and an operator's note beside the dump would have gone with it. The new test fails on the previous check — two failures — and passes on this one, so it is not passing for the wrong reason. And the scraper's log level: disabled is the normal state and stays at debug, but enabled with no endpoint or key is a broken configuration the operator switched on and cannot see failing, since debug is off in production. It warns now, and saveSettings() refuses an empty endpoint the way it already refused an empty key. Smaller: PeriodicalAdminController read the mode twice per request, where a concurrent change between the two reads would render the mastheads list in Simple mode; a mobile test looked up emeroteca_contributi outside the try that guards its neighbours, so a missing table took down ETag tests for unrelated endpoints; and a German string lost its reference to the Emeroteca section. That key turned out to be orphaned — the code now uses the version carrying the detected value — so it is removed from all five locales rather than retranslated. Its absence from the code was confirmed with a search that found the replacement key, so the check could not have passed by failing to run. Verified: PHPStan level 5 clean, 963 assertions across ten suites including the new backup case, the three browser suites and the mobile contract green, locale parity intact, and the two findings that were mine proven in the browser in Simple mode — the filter kept view=titles, and the spoglio tab's masthead filter listed all 106 mastheads. Mode restored afterwards.

Two defects found by reading the logs of two production installs on shared hosting (

Nothing ever pruned them.On the two installs: 33 and 27 of them, 17 MB, spanning December 2025 to June 2026. They only stopped growing because the code that created them was removed; on any install that predates that change they are still sitting there.
They are now rotation candidates in one shared pool with the archives. Separate pools would let the operator watch a recent entry disappear while an older one survived — which is not what the single list they are reading implies.
