fix: survive broken D2L topics, honest body-state reporting, URL escaping, credential-leak fix - #14
Conversation
D2L stores some /content/enforced/ URLs with characters that are not
legal in a URI path: literal spaces, a bare '%' that is not the start of
an escape ("5% (Vinegar).pdf"), and '#' in filenames ("Quiz #3 …").
These reached downloadFileBody (archive update) and resolveFileURL
(download) verbatim, where url.Parse either failed outright
("invalid URL escape") or silently reinterpreted everything after '#'
as a URL fragment, so the request hit a truncated path and 404'd.
The new internal/urlutil package re-encodes the path portion of a
reference (preserving already-valid %XX sequences, keeping query
strings intact) before it is resolved against the LMS base URL. Both
download paths now route through it.
A single un-fetchable topic aborted the entire archive pass:
archiveCourseV2 returned on the first fetchTopicFor error, which meant
D2L's stale "broken" TOC entries (still listed, flagged isBroken, 404 on
the topics API) permanently blocked every course queued after them —
on the live store that was one dead 2022 dropbox link in Marketing
stopping all six courses from converging.
archiveCourseV2 now:
- skips TOC topics D2L flags with IsBroken without an API call,
- counts a failed metadata fetch and continues with the next topic
(the topic is left unrecorded, so the next pass retries it),
- still aborts the whole run on 401/403, reported as a clear
"session expired; run 'schooltools login'" error instead of a raw
status line.
The update summary and --json envelope gain topicsFailed / topicsSkipped
counters; --dry-run counts broken topics so the plan matches what a real
pass will do.
Status and search trusted the index's currentBody pointer instead of the filesystem. On the live store that surfaced as "Bodies: 326 present, 8 missing" while 186 referenced blobs were actually gone from disk — the old prune bug's damage was invisible until archive update --dry-run reported 201 bodies to fill. LoadStatus now stats each blob, Search gains a WithBodiesOnDisk filter (used by find --with-bodies) and --missing-bodies now also matches topics whose pointer exists but whose blob does not. HasBody on SearchHit and FileTopic reflects on-disk state. Export keeps the old pointer semantics so its "skipped-missing-body" reporting is unchanged.
…ookies fetchPost unconditionally printed request headers and raw Set-Cookie values for every form POST, even with Verbose:false — and every auto-refresh path (cmd/whoami.go loginFn) hard-codes Verbose:false. A single `archive update` against an expired session therefore leaked the ADFS SAMLRequest URL and the d2lSessionVal/d2lSecureSessionVal cookie values to stderr, violating the SECURITY.md threat model. fetchPost now takes Options and only dumps when verbose, matching fetchGet. Additionally, even in verbose mode SAML parameters (SAMLRequest/SAMLResponse/RelayState) are replaced with a length marker and cookie values are truncated, mirroring the existing per-hop dump.
…umns splitTimerFields required two day-of-week tokens, so any row whose LAST column was a placeholder (a timer that has never fired) was dropped entirely and status printed no "Next run" at all. When only PASSED was a placeholder, the tail anchoring consumed the "-" as the unit name, reporting Unit="-" and ACTIVATES=<timer name>. The parse now anchors on the final UNIT/ACTIVATES tokens and treats placeholder columns explicitly; the CLI omits the "(…)" suffix when no relative time is available.
Uninstall built a `removed` slice it never read and had two identical return branches. Install printed renderExecStart's volatile-path warning straight to stderr instead of routing it through Status.Warnings, so --json output could not see it; it now goes through the same warning channel as the legacy-ExecStart warning. legacyExecStart also treats a unit file with no ExecStart line at all as needing an upgrade.
Reviewer's GuideThe PR hardens archive convergence against bad D2L topics, repairs malformed content URLs, makes body status/search reflect actual files, closes unconditional login credential logging, and improves systemd status and warning handling, with focused regression tests across each behavior.

**SAML credentials reach logs**
When verbose login logs or sends a SAML-bearing URL as a Referer, `dumpReqHeaders` redacts the request URL but prints Referer values verbatim, and other verbose paths print raw redirect, response, and request URLs or Location headers. SAML parameter values therefore reach stderr and captured logs.
Redact SAML parameters in every verbose URL and header diagnostic, including Referer and Location.
</issue_to_address>
### Comment 2

}
}
</code_context>
<issue_to_address>
**Short cookie secrets reach logs**
When verbose logging prints a credential cookie value of 20 bytes or fewer, `truncateForLog` leaves those values unchanged, so `dumpRespSetCookies` prints the complete credential to stderr and captured logs.
Redact cookie values rather than relying on truncation to protect them.
</issue_to_address>

</code_context>
<issue_to_address>
**Expired downloads continue archive**
When a file-body request returns HTTP 401 or 403, `downloadFileBody` returns an ordinary error or `archiveCourseV2` counts the body error and continues. The archive can finish with missing bodies instead of reporting the expired session.
Return `errSessionExpired` for 401/403 file-body responses and propagate it from the body-error branch in `archiveCourseV2`.
Also at `internal/archive/archive.go:846-848`, `internal/archive/archive.go:978-981`.

+ }
return content.TocResponse{}, fmt.Errorf("D2L API returned %d %s for %s", res.StatusCode, res.Status, res.Request.URL)
</code_context>
<issue_to_address>
**Expired course listing gets wrong error**
When an archive run without explicit course IDs receives HTTP 401 or 403 from the my-courses API, `fetchCoursesPage` returns a generic status error, so `Run` reports a course-list failure instead of the session-expired message.
Have `fetchCoursesPage` return `errSessionExpired` for HTTP 401 and 403.
Also at `internal/archive/archive.go:1069`.
</issue_to_address>
### Comment 5

}
</code_context>
<issue_to_address>
**Login page can be archived as metadata**
When an expired API request redirects to a login page that responds with HTTP 200, `FollowRedirects` follows only one redirect, so an expired-session redirect that ends at a 200 login page reaches `fetchTopicFor` as a successful response. Its JSON-formatting fallback returns non-JSON bytes unchanged, and the archive records the login HTML as fetched topic metadata instead of retrying the topic.
Detect login/HTML responses as authentication failures before the raw-body fallback, and return the session-expired error.
</issue_to_address>
### Comment 6

+func ResolveD2L(base, raw string) (string, error) {
+ if isAbs(raw) {
+ return raw, nil
+ }
+ b, err := url.Parse(base)
</code_context>
<issue_to_address>
**Absolute file URLs remain malformed**
When D2L supplies an absolute file URL with a space, bare percent, or `#` in its path, `ResolveD2L` returns absolute URLs unchanged, and `resolveFileURL` can bypass the helper. The raw path reaches the HTTP client malformed or truncated, so the download fails or targets the wrong resource.
Apply path escaping to absolute URLs too, and ensure `resolveFileURL` routes them through that handling.
Also at `cmd/download.go:320-322`.
</issue_to_address>
### Comment 7

- if 4 < secondDOW {
- left = f[4]
+ next = strings.Join(rest[:4], " ")
+ if rest[4] != timerPlaceholder {
+ left = rest[4]
</code_context>
<issue_to_address>
**Timer status loses last run**
When `systemctl list-timers` reports NEXT as `-` and a real LAST datetime, `splitTimerFields` treats the sole weekday token as identifying a real NEXT datetime, so it builds a bogus next-run value from placeholder and LAST fields and loses the actual last run.
Distinguish a placeholder NEXT from a real NEXT before assigning the remaining fields, and parse LAST when NEXT is `-`.
Also at `internal/systemd/systemd.go:368-370`.
</issue_to_address>
### Comment 8

+ path, query = raw[:i], raw[i:]
+ }
+ return encodePath(path) + query
+}
+
</code_context>
<issue_to_address>
**Question marks truncate filenames**
When a D2L filename contains a literal `?`, `CleanPath` treats the first `?` as the query delimiter, so the filename remainder is sent as query data and the request targets the wrong path.
Encode literal question marks in the path without treating them as the start of a query.
</issue_to_address>
### Comment 9

</code_context>
<issue_to_address>
**Fetch failures can still stop iteration**
When a metadata fetch fails while later topics remain queued, `archiveCourseV2` can increment `TopicsFailed` and then stop processing the course, yet `TestRunSurvivesBrokenAndFailingTopics` still passes: line `at` makes the 404 topic the last topic, and the only healthy topic was processed before it. The counter and index assertions therefore do not prove that processing continues after a failure.
Add a healthy topic after the failing topic and assert that it is archived.

+ }

+ want := ft.TopicID == 1
+ if ft.HasBody != want {
</code_context>
<issue_to_address>
**Empty file-topic results pass**
When `FileTopics` returns an empty slice, `FileTopics` can return no topics and `TestFileTopicsHasBodyChecksDisk` still passes: the loop at line `ec` executes zero times, so neither expected `HasBody` value is checked.
Assert the returned topic count or expected topic IDs before checking their `HasBody` values.
</issue_to_address>
### Comment 11

+ {TopicId: 6003, Title: "Vanished", LastModifiedDate: "2026-03-02T00:00:00Z"},
+ }}}}
</code_context>
<issue_to_address>
**Broken topics can still be fetched**
When the implementation calls the topics API for a topic marked broken but still counts it as skipped, `archiveCourseV2` can fetch topic 6002 and then count it as skipped, yet `TestRunSurvivesBrokenAndFailingTopics` passes because it checks `TopicsSkipped` but never checks `f.topicCalls[6002]`. The fake records that call, so the test does not verify the promised no-API-call behavior.
Assert that `f.topicCalls[6002]` remains zero after the run.
</issue_to_address>
### Comment 12
<location path="internal/login/login_test.go" line_range="44" />
<code_context>
+ }
+
+ out := captureStderr(t, func() {
+ _, _ = fetchPost(srv.URL, "UserName=x", "", jar, Options{})
+ })
+ if out != "" {
</code_context>
<issue_to_address>
**Nonverbose POST can be skipped**
When `fetchPost` returns early for a nonverbose call without sending the POST, `fetchPost` can return without making the request when `Verbose` is false, yet `TestFetchPostDumpsOnlyWhenVerbose` passes because line `br` discards the response and error and only checks that stderr is empty. The verbose call does not verify that the nonverbose call reached the server.
Assert the nonverbose call succeeds and have the test server verify that it received the POST.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 12 findings to address first, and if the URL repair resolves a file reference to the wrong resource, the downloaded bytes can be saved as that topic’s body and remain in the archive after reverting; the affected body can be cleared and fetched again. The login changes reduce credential exposure, but the main persistent risk in this diff is incorrect archived body data.
Blocking findings: internal/login/login.go:557, internal/login/login.go:545, internal/archive/archive.go:1069, internal/archive/archive.go:1047, internal/archive/archive.go:1070, and 7 more

Review comments at @internal/archive/archive.go:
- Line 1183: Update fileExists to treat a path as missing only when os.Stat
returns an error matching fs.ErrNotExist; treat other errors as present or
surface them. This preserves correct missing-body behavior in FileTopics,
bodyOnDisk, and LoadStatus.
- Around line 846-853: Update the topic-fetch error handling around
errSessionExpired to distinguish HTTP status errors from transport errors
returned by httpclient.FollowRedirects. Abort the run or stop retrying after a
bounded number of consecutive transport failures, while preserving the existing
continue behavior for ordinary HTTP failures.
- Around line 975-981: Update the ResolveD2L call to store its result in a
separate variable, preserving rawURL for the error message; assign the resolved
value back to rawURL only after the error check succeeds.
Review comments at @internal/archive/resilience_test.go:
- Around line 66-83: Extend the resilience tests to cover a 403 response from
the TOC endpoint: configure the fake server to reject the TOC request, then
assert that both Run and Diff return errors matching errSessionExpired with
errors.Is. Keep the existing topic-request coverage unchanged.
Review comments at @internal/login/login_test.go:
- Around line 15-28: Update captureStderr to restore os.Stderr and close the
pipe writer with deferred cleanup, including when fn panics or calls t.Fatal.
Drain the reader concurrently while fn runs so writes larger than the pipe
buffer cannot block; return the captured output after the reader completes.
Review comments at @internal/login/login.go:
- Around line 544-545: Update the Set-Cookie logging logic to split off cookie
attributes at the first semicolon before splitting the name and value at the
equals sign, so truncateForLog receives only the cookie value and cannot expose
a short token alongside attributes.
Review comments at @internal/systemd/systemd.go:
- Around line 227-228: Update `Uninstall` to check removal errors for `svcPath`
and `tmrPath`, ignoring only errors matching `os.ErrNotExist` and returning all
other removal errors. Preserve the existing daemon-reload behavior while
ensuring `Uninstall` does not report success when either unit file could not be
removed.
- Around line 345-348: Update both timer-parsing branches that assign `left`
from `rest[4]` to capture the complete `LEFT` field and join its tokens with
spaces; preserve placeholder handling and use the branch’s surrounding fields to
determine the field boundary.

q.Get(k)reads only the first value of a key.q.Setthen replaces every value of that key. This is safe. The query key match is case-sensitive, so asamlrequestkey is not redacted. Servers usually treat SAML parameter names as case-sensitive, so the risk is low. The function is otherwise correct.

ResolveD2L returned absolute URLs unchanged, so a D2L URL with a space, bare % or # in its path still reached the HTTP client malformed; resolveFileURL (download) also short-circuited before the helper. Absolute URLs now go through the same path encoding, and both call sites route everything through ResolveD2L. A literal '?' in a filename was being treated as the start of a query string, truncating the requested path. D2L file URLs never carry a query, so '?' is now encoded as a path character (%3F).
…nd 401 bodies Three paths still mistook an expired session for ordinary data: - the my-courses listing 401'd and surfaced as a course-list failure instead of "session expired"; - a topic request that redirected to the D2L login page returned HTTP 200 with text/html; the pretty-JSON fallback stored the login HTML as the topic's metadata blob; - a 401/403 on a file-body download was counted as a body error, so the run completed with missing bodies and exit 0 while the session was dead. fetchCoursesPage, fetchTopicFor and downloadFileBody now map 401/403 (and login-page responses) to errSessionExpired; the body-error branch propagates it as a fatal run error. Also strengthens TestRunSurvivesBrokenAndFailingTopics: a healthy topic is now queued after the failing one (proving the pass continues), and the test asserts the broken topic is never requested.
The loop over FileTopics ran zero times when the global index was missing, so the test passed vacuously. The test now seeds the global index and asserts the returned topic count.
…lues The first pass redacted only the request URL. Verbose mode still printed the Referer header — which during the ADFS flow is the previous hop's URL carrying a SAMLRequest — plus Location headers, redirect targets, POST form actions and GET-failure URLs. All verbose URL prints now go through redactSAML. Cookie values were only truncated at 20 bytes, so short credentials printed in full. dumpRespSetCookies and the per-hop dump now redact the value entirely (keeping the name and attributes, which is what the Expires/Max-Age debugging actually needs).
With a single day-of-week token the parser assumed it began a real NEXT datetime, so a NEXT="-" row (timer with no next elapse but a past run) produced a bogus next-run built from placeholders and lost the real LAST. Query also skipped such rows before parsing because it filtered on the first field being a weekday; it now filters on the line carrying the timer unit name, which distinguishes data rows from the header and summary lines directly.

…solve errors Review follow-ups from CodeRabbit/cubic: - A transport-level failure (connection refused, DNS, timeout) is now wrapped as errTransport so archiveCourseV2 can tell it apart from a per-topic HTTP failure. A network outage no longer sends one doomed request per topic and exits 0: the pass aborts after 5 consecutive transport failures, in both the metadata and body loops. Per-topic HTTP failures (404 on a deleted topic) keep the existing continue behavior and do not consume the budget. - downloadFileBody now rejects a final login URL before reading the bytes: an expired session redirects the download to the D2L login page, which answers 200 with HTML that would otherwise be hashed and stored as the topic's body. Content-Type is deliberately not checked — D2L serves real .html topic files as text/html. - The resolve error message kept the resolved URL, not the input: "resolve https://…" was printed with the encoded value instead of what D2L actually supplied. - fetchTopicFor now closes the response body on its early returns; repeated 404s otherwise retain connections for the whole pass. - fakeD2L guards topicCalls with a mutex (the handler goroutine wrote it while the test read it) and gains a hijack knob so the transport path is exercised for real, plus tests: consecutive-transport abort, HTTP failures not consuming the budget, and a 403 TOC for both Run and Diff.
fileExists returned false for any os.Stat error, so a permission or I/O error reported a present body as missing — LoadStatus, FileTopics and bodyNeeded all read that as "fetch it again". Only positive non-existence now counts as missing. LoadStatus.BodiesPresent also counted non-File topics that still hold a body while FileTopics/MissingBodies only cover file-compatible topics, so the two halves of the status line disagreed. The on-disk check is now restricted to the same topic set.
Uninstall discarded both os.Remove errors, so a permission error left
the unit files on disk while the caller was told everything was
removed. Only os.ErrNotExist is ignored now; anything else is joined
and returned. Uninstall is also a no-op again when nothing was
installed — it no longer runs daemon-reload just to surface that
command's error.
splitTimerFields took LEFT as a single token, but systemctl prints it
as display text ("29min left", "1h 42min left"): the word "left" was
dropped and, with a multi-token LEFT, the parse could mis-align. LEFT
is now the token range up to the next known column, joined with
spaces. Placeholders are "-" everywhere but "n/a" on systemd 249+, so
both are recognized, and an all-placeholder NEXT normalizes to empty
so status renders no "Next run: n/a (in )" line.
captureStderr restored os.Stderr with a plain statement, so a panic inside fn left stderr redirected for the rest of the test binary, and it read the pipe only after fn returned, so a write larger than the pipe buffer deadlocked. The writer now closes and stderr restores in a deferred func, and the reader drains concurrently. The httptest handler incremented a plain int the test goroutine read back, which -race flags. The counter is an atomic.Int32 now.
…en column A --dry-run whose only leftovers are topics D2L flags broken printed "Nothing to do — your archive is up to date", which is not true: those topics will never be archived. It now prints a distinct no-fetchable-work line naming the broken topics. The dry-run per-course table counted broken topics in Total without a Broken column, so the row columns did not add up; the column is there now. Also adds a table test for resolveFileURL, the download route's URL handling (spaces, %, #, an existing escape, a relative reference with a colon, an absolute URL, and the empty string), matching the CHANGELOG claim that both routes were fixed.

A fatal return from the topic/body loops skipped SaveCourseIndex, so every topic fetched earlier in that pass was written as a blob and then forgotten: unreferenced blobs in an append-only store, and index updates dropped on the floor. Both abort paths (session expired, consecutive transport failures) now persist the accumulated index first, joining any save error into the abort. TestRunAbortsAfterConsecutiveTransportFailures now fetches two topics cleanly before the outage and asserts both survive in the index while the unreachable ones stay absent.
Making fileExists tolerant of non-not-exist stat errors was right for the status/search/refetch paths (a permission error must not read as "missing body"), but it also applied to archive verify, which would have passed blobs it could not actually stat. verify now uses statOK, which surfaces the stat error: a blob that is present but unreadable is reported as unreadable-*-blob rather than missing-*-blob, and verify no longer reports OK for it. Adds a test that reproduces a non-not-exist stat failure deterministically (the blobs path is a regular file, so stat returns ENOTDIR).
When both a unit-file removal and daemon-reload failed, the reload branch returned first and the caller never learned a unit file was still on disk. The removal error is now joined into the reload error (errors.Join ignores the nil case, so a reload-only failure reads exactly as before).
…lute URLs isAbs matched only the lowercase "http://" / "https://" prefixes, so "HTTPS://files.example.com/a.pdf" fell through to the relative path and got a "./" prefix — the download would then have targeted the D2L base instead of the file host. Schemes are case-insensitive per RFC 3986; isAbs lowercases before matching.
The updated fixtures had drifted to using only "n/a", leaving the pre-249 "-" form untested on a passing parse. A table test now runs the never-fired and placeholder-NEXT shapes against both spellings.
The reader goroutine sends on an unbuffered channel; if fn panics, nobody receives, so the goroutine leaks with the captured bytes still in flight. A one-slot buffer lets it finish after the deferred cleanup.

… fails Follow-up to the abort-persistence fix, and a hole that predates it: when a topic is queued as "modified" and its body download then fails, the index recorded the new LastModified (and new metadata blob) while keeping the old currentBody. The next pass then saw matching metadata plus an existing blob and skipped the changed body forever — silent staleness with nothing in the counters to show for it. The pointer is now cleared whenever the body isn't saved for a modified topic (download failure and blob-save failure alike). The blob is never removed and BodyVersions still names it, so nothing is lost; the topic simply stays eligible for a body retry, which the next pass performs as body-missing convergence work. TestModifiedTopicWithFailedBodyStaysEligible seeds six modified File topics whose bodies 404, asserts every pointer is cleared while the new metadata timestamp sticks, and then asserts a recovery pass re-fetches all six bodies. It fails without this change.

Four fixes found while debugging a live archive that had silently stopped converging, plus a credential leak found along the way. Each concern is its own commit.
1.
archive updateaborted the whole pass on one bad topicD2L keeps stale TOC entries flagged
IsBroken(still listed, 404 on the topics API) — e.g. a dead 2022 dropbox link in Marketing.archiveCourseV2returned on the firstfetchTopicForerror, so that single topic blocked every course queued after it; the pass never completed and the per-course index was rolled back.session expired; run 'schooltools login'.--jsongaintopicsFailed/topicsSkipped;--dry-runreports broken topics.Live verification: the fixed binary scanned all 6 courses and exited 0 (
394 checked, 9 fetched, 383 unchanged, 2 skipped (broken)), where the old binary aborted at course 3 every time.2. D2L file-body URLs with unescaped characters
url.Parsefailed onAcetic Acid, 5% (Vinegar).pdf(invalid URL escape "% ("), and a raw#in filenames (Quiz #3 …) was reinterpreted as a URL fragment, truncating the path to a 404. Newinternal/urlutilre-encodes the path portion (preserving valid%XXsequences and query strings); botharchive update's body download anddownloadroute through it.Live verification:
Acetic Acid, 5% (Vinegar).pdf(263 KB) is now archived.3. Status/search trusted index pointers instead of the filesystem
LoadStatuscounted a body present whenevercurrentBody != ""without stat-ing the blob, andfind --with-bodies/--missing-bodieshad the same blind spot — a store with 186 dangling pointers reported "8 missing" while--dry-runsaid 201.LoadStatusnow stats each blob; search gainedWithBodiesOnDisk(used byfind --with-bodies) and--missing-bodiesmatches pointer-set-but-blob-missing. Export keeps the old semantics so its skip reporting is unchanged.Live verification: status went from "330 present, 8 missing" to the honest "337 present, 10 missing";
find --missing-bodieswent 8 → 16.4. Login dumped credentials to stderr unconditionally
fetchPostprinted request headers and rawSet-Cookievalues on every form POST regardless of verbosity, and every auto-refresh path hard-codesVerbose: false— so anyarchive update/loginagainst an expired session leaked the ADFSSAMLRequestURL andd2lSessionVal/d2lSecureSessionValvalues (into journald under the systemd unit), violating SECURITY.md's threat model.fetchPostnow takesOptionsand dumps only behind--verbose; SAML parameters are length-redacted even in verbose mode; cookie values are truncated like the existing per-hop dump.5. systemd housekeeping
splitTimerFieldsrequired two day-of-week tokens, so never-fired timers printed no next-run and a placeholder PASSED made Unit/Activates swap. Also removed deadremovedbookkeeping inUninstall, routed install warnings throughStatus.Warnings(visible to--json), and flagged unit files with noExecStart=line.Testing
go build,go vet ./...,go test -race ./...all clean. New tests:urlutilescaping table + resolve round-trips, archive resilience (broken/404 topics don't abort, 401 does, diff skips broken), body-state on-disk semantics, login dump gating + SAML redaction (stderr captured), systemd field-splitting incl. rows copied from reallist-timersoutput +legacyExecStart. No new dependencies.Not fixed here (data conditions, not code)
~10 File bodies in the live store 404 because the teacher deleted the files from D2L's enforced-content folder, and a handful of topics removed from their courses keep dangling pointers — no code change can recover content the server no longer serves.
archive verifycontinues to report them honestly.Summary by Sourcery
Make archive updates resilient and truthful while hardening URL handling, session diagnostics, credential logging, and systemd maintenance.
