Speasy

What's Changed

Behavior changes:

• An AMDA request longer than max_chunk_size_days is downloaded in several chunks. If one chunk failed quietly, the other chunks were returned as if complete and the hole was cached as empty fragments, served empty forever. Such a request now raises FailedChunkedRequest and nothing is cached.
• Empty cache fragments written before 1.8.2 (previously: before 1.8.1) are no longer trusted and are refetched on read, since 1.8.1 could still write the empty fragments described above. Genuine empty ranges written by 1.8.2+ are kept.
• pysciqlop-cache is now capped below 0.2 until Speasy has been verified against it.

Bug fixes:

• speasy.cda.get_data(..., method='BEST') no longer crashes with AttributeError: 'DatasetIndex' object has no attribute 'filenaming' on datasets CDAWeb does not serve as a file archive (e.g. VOYAGER1_HELIO1HR_POSITION, the ..._LinkTo_..._sscweb ephemeris entries). These now fall back to the web service, as BEST is meant to.

Performance:

• datetime64_to_epoch no longer makes two redundant copies of the time axis.

• perf(time): drop the redundant double-copy in datetime64_to_epoch by @jeandet in https://github.com/SciQLop/speasy/pull/361

• chore: pin pysciqlop-cache below 0.2 until verified by @jeandet in https://github.com/SciQLop/speasy/pull/365

• fix(cda): stop crashing on datasets CDAWeb can't serve as a file archive by @jeandet in https://github.com/SciQLop/speasy/pull/366

• fix(impex): fail a chunked request when a single chunk fails by @jeandet in https://github.com/SciQLop/speasy/pull/367
