logging - Is it good or bad to store log messages in a database table, rather than a file? -


i'm talking human-readable text logging, error messages web application.

do people commonly store these in database? there advantages using database table instead of file? or if not, why bad idea?

database

advantages:

  • way easier search through logs
    • clever queries, grouping , limiting example dates
    • retrieving log messages of specific kind, log level or containing patterns
    • filtering away unwanted noise when looking specific things
  • easier manage in way if you're creating kind of user interface

some disadvantages:

  • pollutes database stuff might not useful, depending on application
  • can aid in far quicker database growth, might annoying in scenarios
  • you need access database (which might require paper work or takes time), or write ui on top

text files

major advantages

  • very easy, light weight, simple implement
  • easy clean away when not needed anymore; no longer wasting disk space

disadvantages

  • hard browse , query (depends on logging statements, file structures etc)

there's nothing inherently right or wrong logging database versus logging file; depends on needs. think through needs, decide. logging database convenient when debugging, might require more of you, team or application in long run.

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). ...
