Housekeeping of PKG_XXXX files

[allanbowe]

SASjs server appears to be missing a housekeeping process - a number of directories are being created in the /tmp folder that are not being removed, see:

Expanding one of these folders, there are numerous files:

Each of which contains a SAS program:

Perhaps it's in relation to the deployment process?

Turns out it must be in relation to the web server - I deleted a bunch of the files and the web apps stopped working!

Perhaps the files can be given more meaninful names, and their presence documented in the developer notes on https://server.sasjs.io ?

files in ./pkg-* are additional files required by our package and part of final executable.

• Why is the /tmp/pkg file created every execution vercel/pkg#1606 (comment)

We cannot explicitly delete these folders,

• other execution which are in-progress depend on these,
• cannot identify which other in-progress execution is mapped to which folder,
• and let these be auto delete by system ( via cronjob OR reboot )

I see. Not ideal - the number of /tmp directories it created for the client was substantial, over a short time period also.

Reboot isn't really an option for a shared environment, nor is cronjob (how can we know which files to remove).

Let's keep this issue open until we have the capacity / resource to assist the aforementioned project with a pull request.
