Le 22/02/2017 Ã 12:18, Esteban Lorenzano a Ã©crit : > thatâs not enough informationâ¦ where it hangs? (when you get the debugger after cmd+.)? It looks like Voyage is trapped in a loop. When I execute the following code in singleton it hangs as well: | orga repo| repo := VOMongoRepository host: 'localhost' database: 'MaBase'. repo enableSingleton. orga := String fromString: 'Pharo'. orga save. Then I can press atl+., I got the attached Pharo debug log. At some point I used wrongly Voyage, from there I got problem. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] [Versionner] Including remote packages

by sergio ruiz

Ah, yes.. actually, i am making something like: ConfigurationOfPrintBot Where the package PrintBot lives on smalltalk hub..Â what i really need to do is get Versionner to reference the REMOTE version of the package, and not the one i have loaded into my image. to solve this, i just edited the configuration by hand.. but i think i just need to reference it differently.. thanks!

forcing window closing

by Raffaello Giulietti

Hi, after 3 minutes working, I'm in a situation where a System Browser window cannot be closed. While the button is there, with tool tip and visual feedback, clicking it simply does nothing. Minimization and maximization still work. Is there a way to force a close?

Hi Hilaire, thatâs not enough informationâ¦ where it hangs? (when you get the debugger after cmd+.)?

Martin's idea of sorting exact matches to the top should satisfy this in practice, without needing another checkbox.

You save the image so that your test case executes immediately upon image startup. For example, by evaluating these two lines together... Smalltalk snapshot: true andQuit: true. 1 inform: 'MY TEST CASE RUN AT IMAGE STARTUP'. This doesn't need to be done in a fresh image, but thats slightly better. If you can't make your test case that tight, more general steps to reproduce are also welcome. Just keep in mind the easier it is to reproduce, the easier it is for others to work on it, and for us to reduce bug bankruptcy [1].

Re: [Pharo-users] Data Encryption

by Alejandro Infante

Hi! If it help Iâm using NaCl to do secure the passwords. You should not store the passwords of your users, not even encrypted. For securing the passwords I use Sha-512 over the salted password. ââââââââââââ User>>initialize super initialize. salt := (Nacl randomBytes: 16) User>>setPassword: aPassword hashedPassword := Nacl hash: (salt , aPassword asByteArray) User>>validatePassword: aPassword ^ hashedPassword asByteArray = (Nacl hash: salt asByteArray , aPassword asByteArray) ââââââââââââ Notice that: 1) I have a different salt for each password, if a bad guy want the passwords he is going to need a different rainbow table for each user. 2) I do not store the password. I do not even store the hash of the plain password. 3) Still Iâm able to validate the password. * Note that Iâm using Nacl>>randomBytes: to generate a cryptographically safe random value. Here is not really necessary, BUT you should use it if you are creating Session-IDs or Tokens. Encrypting the database is *tricky*. You not only have to encrypt the database, but also secure the key. First you need to know how much security you want: 1) Be secure if someone hack into the user running pharo. 3) Be secure if someone steal the server. 4) Be secure if someone has physical access to the running server. (All your keys are in RAM) 2) Be secure if someone hack root. (I doubt anything is going to save you here) For most projects/business (unless working with really sensitive data, such as medical data) securing the OS (users and root) and encrypting the hard-disk should be enough. Also do not forget to encrypt the connections. If everything is on the same server just use https. But you may need more if you use Load Balancers, multiple servers and databases.

Crash in Athens

by Alexander Samoylovich

Hello I am writing graphic demo programs using Athens on Mac Sierra. Time by time Pharo VM crashes. Programs not using Athens work reliably. I believe the behavior is reproducible. How should I report a bug? Alex

This is unfriendly. A Regex checkbox for the two people in the world who can memorize regular expression patterns... Wouldn't be easier to add a "Exact match" check box? There are also uppercase and lowercase issues there.
