git - .gitignore exclusion is not working for a single file - 


$ git --version git version 2.6.4

i realize duplicate other question's answers have not helped.

folder structure 

/ -- dist/ ---- samples/  ---- readme.md ---- foo/ ---- bar/ ---- baz.js

i want ignore in dist except samples , readme.md. first few tries @ didn't work, settled on unignoring readme: 

dist !dist/samples/readme.md

readme brand new file. dist folder not in source control @ all. when check ignore, it's still being ignored: 

$ git check-ignore dist/samples/readme.md  dist/samples/readme.md $ git check-ignore src    # empty line

i've tried:

  1. changing order of ignores
  2. removing slash beginning of line
  3. adding ** in middle: dist/**/readme.md
  4. adding /* end of dist on first line

the other things being ignored *.js, *.js.map, temp , node_modules. funny thing webstorm thinks file not being ignored (it changes color) command line tool does think being ignored.

i don't see i'm doing wrong. pattern seems simple:

  1. ignore things in directory
  2. don't ignore 1 thing here

but it's not working.

the problem because ignoring directory dist. git no longer directory other files.

as explained in this related answer, need whitelist directory , ignore contents. since having nested structure, end being bit complicated though:

# ignore in `dist` folder dist/* # … don’t ignore `dist/samples` folder !dist/samples/ # … ignore inside `dist/samples` folder dist/samples/* # … except `readme.md` there !dist/samples/readme.md

this explicitly mentioned in gitignore documentation (emphasis mine):

an optional prefix "!" negates pattern; matching file excluded previous pattern become included again. it not possible re-include file if parent directory of file excluded. git doesn’t list excluded directories performance reasons, patterns on contained files have no effect, no matter defined.

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
