I have both of these in world: |
| 25 |
|
| 26 |
dev-php/PEAR-Mail |
| 27 |
dev-php/PEAR-Mail_Mime |
| 28 |
|
| 29 |
Let's say PEAR-Mail_Mime depends on PEAR-Mail -- it might, I haven't |
| 30 |
checked, it's just an example. And I remember installing PEAR-Mail_Mime: |
| 31 |
I needed it to receive binary attachments through a contact form on an |
| 32 |
internal site. |
| 33 |
|
| 34 |
I suspect a customer had me install PEAR-Mail so that he could send some |
| 35 |
notifications via SMTP rather than sendmail(). Can I remove it from world? |
| 36 |
|
| 37 |
At the moment, yes I can: PEAR-Mail_Mime depends on PEAR-Mail, so there |
| 38 |
will be no change in my --depclean output. But if I ever take down the |
| 39 |
internal site, and uninstall PEAR-Mail_Mime, depclean will want to |
| 40 |
remove PEAR-Mail, and break that guy's site. This is what that script |
| 41 |
would do. |
| 42 |
|
| 43 |
If I know that I have been careful in the past, this is not a problem, |
| 44 |
since the contents of world will be accurate. However, I'm a little |
| 45 |
worried that I may have forgotten --oneshot and added PEAR-Mail by |
| 46 |
mistake on an upgrade. Now, I have to either risk breaking some |
| 47 |
customer's site, or leave PEAR-Mail in my world file forever. |
