https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=8437 --- Comment #39 from David Cook <dcook@prosentient.com.au> --- That truncated response is 32489 bytes long... I'm guessing the issue is with CGI::Parse::PSGI::Streaming... According to the tools/export.pl, I'm writing a body of 33441 characters... Looking at CGI::Parse::PSGI::Streaming, I'm only seeing 32768 characters (which includes the HTTP headers and the HTTP body), and 32768 bytes is the same as 32KB... CGI::Parse::PSGI::Streaming::Handle shows the full response in the buffer and says it is 33750 characters long... Ah, I think it's a bug in CGI::Parse::PSGI::Streaming::Handle. For some reason, the author takes the data printed to STDOUT, creates an in-memory file handle stored in a scalar variable, and prints the contents of that "STDOUT" to the in-memory file handle, and that's when it is truncated from 33750 characters to 32768 characters... This is the line in CGI::Parse::PSGI::Streaming::Handle which seemingly breaks things: print {$self->{fh}} substr($buf, $offset, $len); The weird thing is that I'm trying to reproduce the problem in a more stripped back program and I can't do it. It just works... -- You are receiving this mail because: You are watching all bug changes.
