json - Parsing HAR file to get a table of HTTP header values -


i parsing har file (chrome devtools generated) using jq. objective "table" (or csv output nice also) list of values of specific http headers returned server, per request url.

to list of request urls, can do:

cat har.json | jq '.log.entries[].request.url'

now like, each request, column urls , next columns corresponding content-encoding , content-type http header values returned in response/headers section.

i managed http headers values following command:

cat har.json | jq '.log.entries[].response.headers[] | select(.name=="content-encoding" or .name=="content-type") | .value'

now mix url , header values. how can that?

there difficulty here because headers may not returned in same order http server.

you use filter this:

[ "url", "content-type", "content-encoding" ], (.log.entries[] | [     .request.url,     ((.response.headers[] | select(.name == "content-type").value) // ""),     ((.response.headers[] | select(.name == "content-encoding").value) // "") ]) | @csv

the key here content type , encoding, need perform search headers separately if want control order appear. there, need format in such way output csv.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
