load_info() calls urlopen() without a timeout and only handles errors raised while opening the URL. If a connection stalls while the response is read, the scraper blocks forever, and the library scan blocks with it, stuck at 0%.

This change:

  • passes a 15 second timeout to urlopen(), matching the TV show scraper;
  • reads the response body inside the existing try block;
  • treats timeouts and socket errors during the read like a failure to reach the site, so it returns the default or an error dict.

The existing error handling then shows a notification and logs a warning, and the scan continues.

I hit this behind a VPN exit node that loses part of the responses to requests sent with Connection: close, which urllib always sends. About half the requests stalled. With the patch they fail after 15 seconds and the scan completes, and requests that don't stall are unaffected.

The log attached to #266 shows the same thing: the last line from the scraper is its first Calling URL for the TMDb search, with no result and no error after it.

Fixes #266

Summary by CodeRabbit

  • Bug Fixes
    • API requests now stop waiting after 15 seconds, improving responsiveness when services are slow or unavailable.
    • Socket timeouts and connection errors now return clearer fallback or read-failure results instead of failing unexpectedly.
    • Response content is handled more consistently for both JSON and text responses.

load_info() called urlopen() without a timeout, and only handled errors
when opening the URL. A connection that stalls while the response is
read blocks the scraper, and with it the library scan, indefinitely.
This happens for example behind a VPN exit node that drops some
responses to requests sent with "Connection: close", which urllib
always sends.

Use a 15 second timeout, matching the TV show scraper, and treat
timeouts and socket errors while reading the response like failures to
reach the site: return the default or an error, so the scraper reports
the failure instead of hanging.

📝 Walkthrough

API requests now use a 15-second timeout. Socket errors return the configured default or a structured read-failure error. Response content is read once and reused for JSON or text decoding.

API requests now give up after 15 seconds of silence, which addresses the fully stalled scans reported in #266. A server that keeps sending data very slowly could still prolong a request, but that was already possible before this change. The change is ready to merge.

Explanation

Issue #266 reports an indefinite scraper freeze at 0%. In python/lib/tmdbscraper/api_utils.py, load_info() now passes timeout=TIMEOUT with TIMEOUT = 15 to urlopen(). The same try block reads the response body. It catches socket.timeout and socket.error during the read and returns the supplied default or an error dictionary. These changes address the reported stalled-request behavior. No explicit automated-test requirement appears in #266.

Explanation

The pull request changes only python/lib/tmdbscraper/api_utils.py. The timeout constant, response-body reuse, and read-error handling directly support the fix for issue #266. The reviewed changes contain no demonstrated unrelated behavior or files.

75-76: 🩺 Stability & Availability | 🔵 Trivial | 💤 Low value

Bound the total response-read time as optional hardening.

urlopen(req, timeout=TIMEOUT) applies to individual blocking socket operations. It does not limit the total time spent in response.read(). A response that sends data before each idle timeout and never reaches EOF can therefore keep the read active indefinitely.

This is a pre-existing edge case. The PR adds the first timeout and covers the fully idle stall described in issue #266. Treat this as optional, low-effort hardening rather than a major issue. If a total deadline is required, read bounded chunks and apply the remaining monotonic-deadline duration to each blocking read.
