Bug ID: 437190 Summary: Wrong order for entries with the same date Product: akregator Version: unspecified Platform: Debian unstable OS: Linux Status: REPORTED Severity: minor Priority: NOR Component: general Assignee: kdepim-b...@kde.org Reporter: danielrosc...@phoenitydawn.de Target Milestone: --- Created attachment 138475 --> https://bugs.kde.org/attachment.cgi?id=138475&action=edit Screenshot showing the wrong order in Akregator SUMMARY When fetching a feed which contains multiple entries with the same date and which contains new entries on consecutive fetches (but still with the same date), the entries are ordered incorrectly in Akregator when ordering by date. STEPS TO REPRODUCE 1. Create a file (e.g. /tmp/wrong_date.xml) with the following content: <?xml version="1.0" encoding="utf-8"?> <feed xml:lang="en" xmlns="http://www.w3.org/2005/Atom"><title>Wrong order for same dates</title><link href="https://example.tld" rel="alternate"></link><id>https://example.tld</id><updated>2021-05-16T00:00:00+02:00</updated><entry><title>Entry 1 from first fetch</title><link href="https://example.tld/1/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>11</id><summary type="html">-</summary></entry><entry><title>Entry 2 from first fetch</title><link href="https://example.tld/2/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>12</id><summary type="html">-</summary></entry><entry><title>Entry 3 from first fetch</title><link href="https://example.tld/3/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>13</id><summary type="html">-</summary></entry><entry><title>Entry 4 from first fetch</title><link href="https://example.tld/4/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>14</id><summary type="html">-</summary></entry></feed> 2. Subscribe to a new feed in Akregator, using the stored file as source (file:///tmp/wrong_date.xml) 3. Fetch the feed in Akregator. 4. Replace the content of the file with the following content: <?xml version="1.0" encoding="utf-8"?> <feed xml:lang="en" xmlns="http://www.w3.org/2005/Atom"><title>Wrong order for same dates</title><link href="https://example.tld" rel="alternate"></link><id>https://example.tld</id><updated>2021-05-16T00:00:00+02:00</updated><entry><title>Entry 1 from second fetch</title><link href="https://example.tld/1/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>21</id><summary type="html">-</summary></entry><entry><title>Entry 2 from second fetch</title><link href="https://example.tld/2/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>22</id><summary type="html">-</summary></entry><entry><title>Entry 3 from second fetch</title><link href="https://example.tld/3/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>23</id><summary type="html">-</summary></entry><entry><title>Entry 4 from second fetch</title><link href="https://example.tld/4/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>24</id><summary type="html">-</summary></entry></feed> 5. Fetch the feed in Akregator again. 6. Replace the content of the file with the following content once again: <?xml version="1.0" encoding="utf-8"?> <feed xml:lang="en" xmlns="http://www.w3.org/2005/Atom"><title>Wrong order for same dates</title><link href="https://example.tld" rel="alternate"></link><id>https://example.tld</id><updated>2021-05-16T00:00:00+02:00</updated><entry><title>Entry 1 from third fetch</title><link href="https://example.tld/1/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>31</id><summary type="html">-</summary></entry><entry><title>Entry 2 from third fetch</title><link href="https://example.tld/2/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>32</id><summary type="html">-</summary></entry><entry><title>Entry 3 from third fetch</title><link href="https://example.tld/3/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>33</id><summary type="html">-</summary></entry><entry><title>Entry 4 from third fetch</title><link href="https://example.tld/4/" rel="alternate"></link><published>2021-05-16T00:00:00+02:00</published><updated>2021-05-16T00:00:00+02:00</updated><id>34</id><summary type="html">-</summary></entry></feed> 7. Fetch the feed in Akregator again. OBSERVED RESULT When sorting by date, the entries are sorted with the following order: Entry 1 from first fetch Entry 1 from second fetch Entry 1 from third fetch Entry 2 from first fetch Entry 2 from second fetch Entry 2 from third fetch Entry 3 from first fetch Entry 3 from second fetch Entry 3 from third fetch Please note that the titles of the entries are not the reason for this sort order. This happens with arbitrary titles as well. I've also attached a screenshot showing how this looks in Akregator. EXPECTED RESULT I'd expect entries with the same date from different fetches to be sorted by the time of fetching: Entry 1 from third fetch Entry 2 from third fetch Entry 3 from third fetch Entry 1 from second fetch Entry 2 from second fetch Entry 3 from second fetch Entry 1 from first fetch Entry 2 from first fetch Entry 3 from first fetch SOFTWARE/OS VERSIONS Linux/KDE Plasma: Akregator version: 5.15.3 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION There is also another unrelated bug shown in the screenshot. Akregator sometimes seems to have some kind of off-by-one error when the publishing date of an entry is exactly at midnight. -- You are receiving this mail because: You are watching all bug changes.
