I have seen multiple last-chunks from other web servers, not sure if it the same problem. This came from a php-page. Multiple last-chunks causes my web proxy, rabbit, to read the extra last chunk as the next http header in the keepalive stream. This results in broken images. If I do not use a proxy mozilla seems to silently remove the extra last-chunk. I have a ethereal trace when this happens if anyone wants it. Seems to happen often, but non-deterministacally on http://www.eet.gr/ Reclassified this because it's not always going to be possible for a module author to know that a flush is ending the entire stream, depending on the protocol they are trying to implement. The eos bucket handler is gonna have to get a brain on this point, or else the flush bucket handler is gonna have to learn not to flush nothing. Either way the flaw is probably in the chunk protocol filter itself. Whoops, off to core with this. From my point of view this problem is independant of the flush bucket. I guess we see this problem if pass the eos bucket twice thru the chunk filter in different invocations (=> and in different brigades). I guess the possible approach to solve this in the chunk filter is to remove the chunk filter from the filter chain once we see an eos bucket in the chunk filter. Why is this not simply a bug in whatever handler generated multiple EOS buckets? Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd. As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd. If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question. If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with. Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated. |
