Module: HTTP::Recorder Version: perl -MHTTP::Recorder -e 'use HTTP::Recorder; print HTTP::Recorder->VERSION, "\n";' 0.05 OS Environment: uname -a Linux bitspot 2.6.9-11.ELsmp #1 SMP Wed Jun 8 17:54:20 CDT 2005 i686 i686 i386 GNU/Linux Perl Version: perl -v This is perl, v5.8.5 built for i386-linux-thread-multi...

Comment: I see that multiple users have been experiencing this problem, and nobody is offering any useful help: http://aspn.activestate.com/ASPN/Mail/Message/perl-macosx/2789778 http://lists.bestpractical.com/pipermail/http-recorder/2005-August/000058.html Note that while for the first case, Gisle Aas offered a suggestion, that suggestion did not fix the problem. Neither of the above two posters is me. I am trying something very, very simple, a login to a two-field form page, through Firefox which is pointing to the proxy. It is writing to the log file, but the submit is not going through in the browser, so the browser stays at the login page without logging in, and the script prints out the error message pasted above. Please visit your email lists and relevant web sites and tell people how to fix this! Thanks!

[guest - Wed Aug 31 20:49:07 2005]: The problem seems to appear when $self->unmodify is called passing it a plain string and not the expected URI::QueryParam object. This appear on line 314: 312 # undo what we've done 313 $request->uri($self->unmodify($request->uri)); 314 $request->content($self->unmodify($request->content)); 315 It seems that commenting that line prevent HTTP::Recorder to crash but I'm aware of others implications of this change.

Thanks. So is there a way to change the plain string into a URI::QueryParam object before that call? Show quoted text

If you are aware of other implications, would it be possible for you to please mention what those implications are? Thanks very much in advance.

The trunk build does not return error for me but it does not record interaction with websites. I am using FreeBSD 4 with perl 5.6. On Fri Jan 13 07:39:37 2006, neuhaus wrote: Show quoted text

Here's a patch that fixes this issue for the most recent version on CPAN ( 0.05 ) It applies cleanly and solves the problem without bypassing the functionality of the code that throws the error (it recasts the string as a URI::http object before query_params() is called on it) Initially I emailed the author directly, because RT was down, but this way anybody else who encounters this bug can just apply this patch to the unpacked tarball before building.

Bug was fix, thanks for the patch. - Shmuel.
