perl - perlbrew fails with "Can't locate Devel/PatchPerl.pm" -


perlbrew fails can't locate devel/patchperl.pm.

more precisely, fails run of patchperl spawned off perlbrew.

there is in fact devel/patchperl.pm accessible via paths in environment variable perl5lib, perlbrew unconditionally deletes variable before runs perlpatch:

delete $env{$_} qw(perl5lib perl5opt);

i can't find in perlbrew documentation justifying maneuver.

can explain why perlbrew this?

edit:

below bash script reproduces problem. run (with suitable <path_to_script>):

% env -i home=$home shell=/bin/bash /bin/bash --noprofile --norc bash-3.2$ /bin/bash --norc --noprofile <path_to_script>

the script's running time 4 minutes on machine. last few lines of output, including lines showing error below:

(cd /tmp/perlbrew_root/build/perl-5.16.3 && rm -f config.sh policy.sh && patchperl && sh configure -de '-dprefix=/tmp/perlbrew_root/perls/perl-5.16.3' '-a'eval:scriptdir=/tmp/perlbrew_root/perls/perl-5.16.3/bin'' && make  && make test_harness && make install) 2>&1 | tee /tmp/perlbrew_root/build.perl-5.16.3.log can't locate devel/patchperl.pm in @inc (@inc contains: /library/perl/5.12/darwin-thread-multi-2level /library/perl/5.12 /network/library/perl/5.12/darwin-thread-multi-2level /network/library/perl/5.12 /library/perl/updates/5.12.3 /system/library/perl/5.12/darwin-thread-multi-2level /system/library/perl/5.12 /system/library/perl/extras/5.12/darwin-thread-multi-2level /system/library/perl/extras/5.12 .) @ /tmp/testperl/bin/patchperl line 12. begin failed--compilation aborted @ /tmp/testperl/bin/patchperl line 12. perl-5.16.3 installed.

the last line of output above (perl-5.16.3 installed.) nonsense: real build , installation of perl-5.16.3 take 1 order of magnitude longer script's running time, which, stated, 4 minutes on machine.

note @inc in error. don't see how patchperl possibly find devel/patchperl.pm, under /tmp/testperl/lib/perl5, given @inc.

upgrade perlbrew (perlbrew self-upgrade or shell bootstrap incantation http://perlbrew.pl/).

recent versions install patchperl $perlbrew_root/bin through perlbrew install-patchperl.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
