[Pharo-users] Finder blows me away again

[Ben Coman]

Just sharing...

I wondered if there was a better way of converting an array of strings into
one string than doing this...

x := #(
'++'
'||'
'++') .
x flatCollect: [  :c | c ]

but it was awkward copying the array twice into Finder.


So I wondered if it could do variable assignment, and it can!!

i.e...

textfield.

Haha ... this is why backup and restore functionality has been built

Backup and restore?


This would be a valid alternative to doing `bu snapshot` (a form of 
backup) and newExtent ...


In GsDevKit_home, use $GS_HOME/bin/todeBackup and 
$GS_HOME/bin/todeRestore to do a backup and restore ... these are bash 
scripts that call the tODE commands `bu backup` and `bu restore`, you 
will see docs for these commands when do the `man bu` ...


if you are doing regular production backups (which you should be) you 
could simply restore from backup into your sandbox stone, whenever you 
want to start with a fresh extent ...


While we are at it, take a look at the bash script $GS_HOME/bin/todeIt 
that allows you to call tode commands from bash ... a convenient way for 
you to do your deployment scripts, where you can write your own tODE 
command line scripts and then call them from bash ...


With GemStone 3.5.0 (not yet released), it will be practical to write 
topaz/smalltalk/stash[1] bash command line scripts for deployment ... I 
plan to give a talk on stash[1] at ESUG this year:)

I would like to use GsDevKit_home, but I want to make sure that the 
use case I am envisioning is in keeping what this package is set up to do.


My vision is something like:
- Deploy a stone to remote production server.
- Develop in the latest version of Pharo on my local machine, keeping 
my project in git.
- When it's time to deploy,  use tODE client to tell the production 
server to grab the latest code, and we're done.
This sounds okay ... I'd be inclined to have you also include a sandbox 
or QA stone in your setup, that is either a copy of the production db, 
or a db filled with test data, that you would use to validate your 
update process/code before each release to production ... better safe 
debugging in a sandbox, than sorry debugging in a production db:)


Does this sound reasonable?

Also, one thing that I find invaluable in troubleshooting applications 
written using relational databases is to be able to be able to just 
dump the production database and load it up on my local machine. Is 
this possible using gemstones?


Good you are thinking along the same lines ... You can take a snapshot 
of an extent in a running stone using the tODE command `bu snapshot` 
(run `man bu` in a tODE shell ) for more details, then using the 
GsDevKit_home bash script, $GS_HOME/bin/newExtent ( 
`$GS_HOME/bin/newExtent -h` for more details) you can install the 
snapshot from production into a local sandbox stone ...


For future questions about GsDevKit_home and GemSTone, please the GLASS 
mailing list[1][2]. There are a number of folks in the wild that are 
using the develop in Pharo, deploy in GemStone model so you'll benefit 
from having those folks weigh in with their approaches as well, without 
cluttering the Pharo newsgroup with GemStone information. Also there are 
few more GemTalk employees that monitor the GLASS list and can weigh in 
with their knowledge as well :)

[Pharo-users] [gemstones] Use case for GsDevKit_home

[sergio ruiz]

I have another project coming up, and I have free reign over the tech
stack. I am gonna use Pharo, but I'd like to spend my up front time on this
project figuring out the things I usually wait until the end to do. One of
these issues is setting up gemstones.

I would like to use GsDevKit_home, but I want to make sure that the use
case I am envisioning is in keeping what this package is set up to do.

My vision is something like:
- Deploy a stone to remote production server.
- Develop in the latest version of Pharo on my local machine, keeping my
project in git.
- When it's time to deploy,  use tODE client to tell the production server
to grab the latest code, and we're done.

Does this sound reasonable?

Also, one thing that I find invaluable in troubleshooting applications
written using relational databases is to be able to be able to just dump
the production database and load it up on my local machine. Is this
possible using gemstones?

Thanks!
