Subject: XML::RSS 1.05 - 2.0-generate test 14 failure
Download (untitled) / with headers
text/plain 878b
The following error was received from my install of XML::RSS 1.05 on Windows NT 4.0. not ok 14 - t/2.0-generated.xml has '1583' characters. # Failed test (t/2.0-generate.t at line 106) # got: '1583' # expected: '1535' # Looks like you failed 1 tests of 25. The error is caused by a bug in the test script. On UNIX (and Cygwin where it also installs just fine), the end of line character is a line feed "\n" character. On Windows, however, its a carriage return and a line feed character "\r\n". The test where the error occurs is checking to see if size of the generated XML file is the size expected. The size its expecting is 1535 bytes. On Windows, it gets 1583. The file is 49 lines long. The difference between the two is 49 bytes. It appears that the test does not take into account the different line endings when calculating the expected size.

The way the test works is the length of the generated RSS is compared to the size of the file when it is serialized to disk. You're saying that this doesn't work under Windows? I would have expected any differences in the newlines characters to have shown up during the initial call to length.

The extra characters are only added when written to a file. They are also "magically" removed when read in. For example, I read the generated XML file back in and performed an "ord" on every character. There are 1535 characters read in as expected. The file in bytes is still 1583.

Subject: XML::RSS ignores output encoding

Sub save in RSS.pm opens an output file without binmode or explicitly specified encoding which makes its output wrong. Attached patch solves the problem for me.

Hmn, I don't have a Win32 system to test on. Can you give some more hints? My guess is that it's a bug in the test rather than in the module. (Until then I'll mark it as resolved).

Sorry, I've opened your ticket by replying by e-mail (the web server is really poor). I've had another go and all the tests pass without problems. Unfortunately, I don't know how many tens of modules were installed on the system in the meantime. The error seen in the past was # Failed test 't/2.0-generated.xml has '1577' characters.' # in t\2.0-generate.t at line 103. # got: '1577' # expected: '1529' # Looks like you failed 1 test of 26. I guess, since your test name includes test result, that it is the 'expected' result that is incorrect (or that you've the comparison function arguments inverted). Anyway, AOK - thank you!
