Service fabric deploy deprecated files from previous deployment -

when redeploying application on service fabric (using publish-upgradedservicefabricapplication ), why see files previous deployment ? file of application seems not deleted or cached somewhere. for example appversiona includes filea appversionb includes fileb result in target _vm "sf/_app" data directory: first deployment appversiona : got appxx/myservice/code/filea : ok then when deploy appversionb replace appversiona : i got appyy/myservice/code/filea and appyy/myservice/code/fileb failed : expected have fileb ! inside applicationmanifest.xml of application had "1.8-snapshot" applicationtypeversion attribute value. so encounter issue when updating , redeploying snapshot version multiples times. seems in usecase - applicationtypeversion unchanged - sf overrides or append deployment bundle content of previous deployment instead of recreating new 1 scratch (for me it's issue). to fix it, add build timestamp applicati

Dialog with permissions language on Chrome extension update -

-
i know in case when extension updated , requires additional permissions compared installed version, dialog permission warnings shown. my question is: dialog going shown if permissions removed compared previous extension version? is dialog going shown if permissions cutted off comparing previous extension version? if permissions decrease, no dialog shown. interesting fact: chrome still consider permissions granted on installs had broad-permissions version before. so if next version reintroduces same permission, users had restricted-permission version first installed version notified. makes easier (but still not trivial) recover accidental permission deletion. from source code (thanks sungguk lim link): // extensions can silently upgrade less permissions, , // silently upgrade version adds these permissions back. // extension release new version // removes "omnibox" permission. when user upgrades, chrome // still remember "omnibox"

statistics - How can I export a counter that resets every restart to bosun and trust the absolute number? -

-
i sending counter can reset @ point. sent counter every 5 seconds don't reset every 5 seconds, when app restarts, regularly. i need able tell how many impressions did server got last week, can't sum() because bosun add 10, 12, 15, 25, 0, 1, 5, 10.... so, take in account rate calculation, not summing or other thing. would bosun handle better if restarted counter every time send it? seems easier, docs on bosun/opentsdb state not necessary , not it. opentsdb should automatically handle sum/average aggregation of counters when use them rate instead of raw gauge. takes 2 sample points , calculates difference, giving total "impressions" between 2 sample points. note may change value "per second" since standard opentsdb. whenever second value lower first, opentsdb disregard datapoint , wait next data point sent before continue rate calculations. reason should try , minimize counter resets or overflows if possible (anything less hour may cause no

How to separate comma separated values in R in a new row? -

i have dataset follow: col1 col2 1,2,3 b ["1","2"] c 4 i want output as: col1 col2 1 2 3 b 1 b 2 c 4 is possible in r? if yes, how? you try csplit "splitstackshape" package: library(splitstackshape) csplit(as.data.table(mydf)[, col2 := gsub("[][\"]", "", col2)], "col2", ",", "long") # col1 col2 # 1: 1 # 2: 2 # 3: 3 # 4: b 1 # 5: b 2 # 6: c 4 of course, i'm highly partial csplit , can use "dplyr" , unnest "tidyr": library(dplyr) library(tidyr) mydf %>% mutate(col2 = strsplit(gsub("[][\"]", "", col2), ",")) %>% unnest(col2) or "data.table": library(data.table) as.data.table(mydf)[, list( col2 = unlist(strsplit(gsub("[][\"]", "", col2), ",&

java - how can I overwrite an object in matlab? -

i have loop in want create object. must share same name each loop. like for i=1:100 car=car(args(i)) %in loop stuff car end the problem @ second iteration matlab tries access element car(args(i)) instead of calling costructor of class car. this error arg=ss error using subsindex function 'subsindex' not defined values of class 'ss'. in java i'd call ''new'' parameter, like car=new car(args); //do stuff car istance car= new car(args); //do stuff new car istance i can't allocate array of ''car'' since each istance several hundreds of megabytes. tried looking keyword similar new in matlab had no luck. the problem you're calling variable same name class. first time define car=car(); , car starts refer instance, rather class, , subsequent calls car() not call class constructor, try access index of object car (as if array, hence error subsindex ). you have careful in matlab not shadow built-in fu

Are FOR loops with char iterators in C possible? -

-
i'm having problem using unsigned char iterator. using following code results in being stuck inside loop. the output looks this. unsigned char i; char * arr; int * freq; arr = (char *)(malloc(256*sizeof(char))); freq = (int *)(malloc(256*sizeof(int))); (i=0; i<=255;i++){ arr[i]=i; freq[i]=0; printf("%c",i); } my question why happens? due using unsigned char iterator? i <= 255 if i of type unsigned char , type 8 bit on platform (which is), expression true , have infinite loop. well-defined behavior, though. unsigned char wrap around , value start @ 0 again once has reached 255. the solution simple of course: change type of i int . to avoid such surprises in future, make sure turn on compiler's warnings. if compile bogus loop gcc , pass -wall , -wextra flags, tell me this. main.c: in function ‘main’: main.c:5:17: warning: comparison true due limited range of data type [-wtype-limits] (i = 0; <= 255; ++i)

i set multiple deployment slots web app. have continuous deployment configured on staging slot, each git commit on specific branch triggers deployment staging slot. once verified, swap staging , production slots. there way view (and redeploy if desired) deployment history slot? don't want limited reverting swap, able select specific deployment. the continuous deployment setting staging slot shows 2 deployments, though there have been many more. there way access full deployment history? when dealing slots, behavior bit complex (and might argue confusing!). trickiness comes fact deployment history moves content of site when perform swaps. i'll illustrate example: you start production slot (i.e. main app), , staging slot. no deployments have happened yet. deployment #1 happens staging slot you swap production at point, see no history in staging slot because history swapped production slot. now deploy #2 staging slot, , swap production. the history on sta
