| # Let us consider the following typical mysql backup script: | |
| mysqldump --routines --no-data -h $mysqlHost -P $mysqlPort -u $mysqlUser -p$mysqlPassword $database | |
| # It succeeds but stderr will get: | |
| # Warning: Using a password on the command line interface can be insecure. | |
| # You can fix this with the below hack: | |
| credentialsFile=/mysql-credentials.cnf | |
| echo "[client]" > $credentialsFile | |
| echo "user=$mysqlUser" >> $credentialsFile | |
| echo "password=$mysqlPassword" >> $credentialsFile |
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
