ruby on rails - On heroku, how to delete files installed by a buildpack that are no longer needed? -


i've started getting slug size errors on deploy:

-----> compiled slug size: 350.4mb large (max 300mb).

my app far small causing this, verified manually inspecting bundle , assets size. upon investigation in one-off dyno, discovered files installed r buildpack still in vendor/ though stopped using buildpack months ago , unset buildpack_url:

~/vendor $ du -h --max-depth 1 90m ./ruby-2.0.0 28k ./plugins 24k ./heroku 122m    ./bundle 113m    ./glibc-2.7 16m ./bin 95m ./gcc-4.3 36m ./ruby-1.9.3 104k    ./assets 87m ./r 1.2m    ./gems 450m    ./libexec 108k    ./redis-rb 1008m   .

deleting them in one-off dyno doesn't it; reappear in new one.

how can make these directories, r/ , gcc-4.3/ permanently go away?

it possible r buildpack placed these files build's cache dir , ruby buildpack still pulling in. unlikely 2 buildpacks conflict way, possible. recommend trying push code brand new app , see if slug size drops. if so, can use third-party/unsupported heroku-repo plugin purge build cache on original app.

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!
