How to remove files with “No Content Changes Found” in Git Desktop

There are 3 possible ways git can find a file changed (even if you didn’t change it)

  1. Line Endings have changed
  2. File permissions have changed
  3. Bonus: if modification time has changed

for first case try these settings in bash shell. One of these will fix it for you

$ git config core.eol
$ git config core.autocrlf
$ git config core.safecrlf

For second case, here is the flag

git config core.filemode false

Bonus One: If Modification time was changed

If your working tree has files with updated “last modification time” and you see a huge list of files with “no content changes found”, try this:

git add .
 // ^ dont use . [DOT] if you want to fix for particular sub-folder

You can do git add for all affected files, after that it stops displaying them as modified in git status (and doesn’t actually stage them for commit if there are no changes).

MySQL error 1449: The user specified as a definer does not exist

Why this error happens?

Most of the times, reason is that your database dump through command line or PhpMyAdmin or even other libraries can have SQL’s Definer statements. Now, as per MySQL’s Official Documentation:

The DEFINER clause specifies the MySQL account to be used when checking access privileges at routine execution time for routines that have the SQL SECURITY DEFINER characteristic.

MySQL Reference Manual v8.0

Solution: MySQL mysqldump create a safe backup to ensure no corruption

Use the following command to create backup of your mysql database. Put the command in terminal

mysqldump -hHOST -uUSERNAME -p DATABASE_NAME | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > BACKUP_NAME.sql

With gzip compression > backup 

mysqldump -hHOST -uUSERNAME -p DATABASE_NAME | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | gzip > BACKUP_NAME.sql
