[Pharo-project] [ANN] elasticsearch client
Hi - Elasticsearch (http://www.elasticsearch.org/) claims to be a: flexible and powerful open source, distributed real-time search and analytics engine for the cloud I put what I've made up here: MCHttpRepository location: 'http://ss3.gemstone.com/ss/Elasticsearch' user: '' password: '' So far it allows you to create an index, add documents, get documents by id, search using the URI Request api, and then delete the index. I made it in Pharo 1.4. I made an attempt to abstract out the HTTP client and URL stuff so it could be used with Zinc or Webclient. But right now it only works with Zinc. If someone wants it to run in Squeak sooner rather than later let me know and I can either fix it and the config or help you do it. basic usage is like this: index:= ESIndex createIndex: 'test-index'. docContent := Dictionary new. docContent at: 'message' put: 'this is the documents content'. docContent at: 'creator' put: 'Mr T'. document:=ESDocument withContent: docContent. document addToIndex:index. search:=ESURISearch index:index. search queryString:'documents'; search. search results explore. ESIndex deleteIndex:'test-index' I haven't begun implementing the QueryDSL but the ESSearch class does do the required GET with a JSON body and does work. Seems like it'd be useful to have the QueryDSL but right now I don't need more than the URI Request searching provides. It also doesn't do any of the cluster health/maintenance api yet

I haven't looked in a while, this is probably possible, and a Fuel visualizer thing rather than a Roassal thing but: Is there a way to hide all the edges pointing to a node unless the node is clicked, or has more fewer than X edges pointing to it, or ..? I'm using Chronos for some things and each Timepoint has a Calendar that it references, but its the same Calendar so every Timepoint draws a line to the Calendar, which can both slow down the drawing incredibly but also mask useful information behind lines.

Re: [Pharo-project] ParseTreeRewrite Limitations
Camillo Bruni-3 wrote
Camille/o were trying to fix a bug in the CriticsRules and found a strange
limitation of the ParseTreeRewriter
Given: Result:
-- ---

self halt.
self bar.self bar.
However this is not possible to specify directly:
RBParseTreeRewriter new
replace: '`@object halt' with: ''.
As the parsed ' ' string will result in a SequenceNode, thus forcing
the original message node ('self halt') to be a sequence node.
So instead of looking for 'self halt' it will look for
||
self halt.
and thus it tries to explicitly match the temporary.
The result is, that we cannot remove 'self halt' with a rewrite rule
if the method/block contains temporaries :/.
Has anybody encountered this, or knows how to directly replace a message
node with an empty node?

You have to edit the higher level node. So find the node with the halt as
a child and do you edits there.

Re: [Pharo-project] Gettext in Pharo2.0
Johan Brichau-2 wrote Hi, Loading Gettext into Pharo2.0 crashes badly (system locks up, eventually an emergency debugger appears). The reason is the class initialization of NaturalLanguageTranslator: Smalltalk addToStartUpList: NaturalLanguageTranslator after: FileDirectory. Because the class FileDirectory is no longer in that list, it crashes. So, my questions: - should it not produce a nicer debugger window? - I can fix the load problem itself and also take a look to port this package to Pharo2.0 if it requires more than adapting the above. But I have no write access to the PharoNonCorePackages repository. Is there a new location? Or is there already a version for Pharo2.0 somewhere? Or should we move it out of that repository and give it it's own special place? cheers Johan I think Gettext should be in its own place, and I don't think there is one for it yet. I think Gettext that worked in 1.3 also doesn't work in Pharo 1.4, which I could look at fixing. Or if it does work in 1.4 let me know how to load it. I made some slime rules for Seaside that run in Pharo 1.3 that automatically find strings and adds the conversion stuff if those strings aren't in methods that end in 'Id' or 'Css' or 'Class' (etc).

Re: [Pharo-project] Squeaksource down, are people using something else?
This works but doesn't permanently change the repos in the configuration and you have to have some way to load the configuration in the first place. It just adds more repos during the load process: MetacelloRepositoriesSpecadd: aStringOrSpec (aStringOrSpec isString and: [ '*squeaksource*' match: aStringOrSpec ]) ifTrue: [ (aStringOrSpec copy replaceFrom: 8 to: 27 with: 'dsal.cl/squeaksource/' startingAt: 1) addToMetacelloRepositories: self ]. aStringOrSpec addToMetacelloRepositories: self MetacelloRepositoriesSpecrepository:aStringOrSpec self add: aStringOrSpec You should also change the networking timeout to something more tolerable than 30 seconds. e.g. ZnNetworkingUtils defaultSocketStreamTimeout:3 And I've only tried it in Pharo 1.4 and only loaded Seaside3.0.7.

Re: [Pharo-project] Squeaksource down, are people using something else?
I need to proofread before sending. After making the two changes to MetacelloRepositoriesSpec you can just load the Configurations in the normal way e.g. ConfigurationOfSeaside30 load. It takes longer because it checks squeaksource first, and waits on a timeout. If you know you don't want to access squeaksource at all change the #add: method to: MetacelloRepositoriesSpecadd: aStringOrSpec (aStringOrSpec isString and: [ '*squeaksource*' match: aStringOrSpec ]) ifTrue: [ (aStringOrSpec copy replaceFrom: 8 to: 27 with: 'dsal.cl/squeaksource/' startingAt: 1) addToMetacelloRepositories: self ] ifFalse: [ aStringOrSpec addToMetacelloRepositories: self ]. Which should remove all the references to squeaksource for the configuration and its dependencies which should make loading things go faster as its not waiting on a timeout. . -- View this message in context: http://forum.world.st/Squeaksource-down-are-people-using-something-else-tp4653990p4654025.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Sabine Knöfel wrote I have an attribute date in a domain object. Last week, I created some objects with this attribute. Today I created objects again with the same date value in this attribute.

Re: [Pharo-project] Anyone want more timezones in the base image?
Thanks for the feedback. Comments below. Sven Van Caekenberghe wrote I had a quick look at your code and it seems like a logical addition (given what TimeZone currently is and what you want to do: interpret tz abbreviations). I have 3 remarks/comments: - the list is currently a dynamic array that is recreated on every access, wouldn't a lazy initialized class variable be better ? Yes of course I would love that but I don't know how to create a class variable when just using extensions on a class. Is there a way? - one other goal of a list of timezones is to present them to the user to pick one; for that TimeZone as it stands now is insufficient (there is no country/city mapping, which is the most user friendly way to pick one, IMHO). it seems a bit wastefull to have such a list and not be able to support that goal as well. I agree but that would entail mapping also when each timezone is in effect in each locale during different times of the year. My Something the Chronos (http://www.chronos-st.org) package does and I think the TimeZoneDatabase from Dave Lewis does. My solution is definitely much simpler and less useful. - on Mac OS X and Linux, there is enough data in /usr/share/zoneinfo to dynamically load/parse from, if something equivalent existed on Windows, we could use that (and benefit from OS level updates to this DB); I know it is more work, I'm just thing out loud. I'm glad you are thinking about it. Dave Lewis's TimeZoneDatabase does this, I think not on windows but I'm not positive. . It also seems to me that adopting the TimeZoneDatabase is natural next step for the TimeZone/Chronology package to go if there's reason to make Pharo better able to handle cross-timezone issues. But it would need to have a source for Olson time zone data on Windows. Dave has created a primitive (primitiveUtcWithOffset) in the interpreterVM that would be good to port to the CogVM.

[Pharo-project] Anyone want more timezones in the base image?
Hi - Because of how Internet Explorer reports javascript dates back to Seaside (as detected by Brian Murphy-Dye when using the FullCalendar jQuery plugin) I added the ability to determine the timezone based on the abbreviation IE reports. I used the list here: https://en.wikipedia.org/wiki/Time_zone_abbreviations to create an expanded version of TimeZone class#timeZones which encompasses those shown in the list on wikipedia. And added some convenience methods. Its not as useful or sophisticated as David Lewis's TimeZone database or Chronos, but its more than what's in the image now. If someone wants it I can make an issue and package my changes up for review. Right now I'm just including them as extensions to the JQWidgetBox-JQFullCalendar-Core package.

If its for a new installation use bcrypt or SHA512 to hash the passwords. bcrypt is better because its slower, and allegedly future proof. to get a hashed password use BCryptLinuxFFI bcrypt:'mypassword' to check it against a stored hash use: BCryptLinuxFFI check:'mypassword' against: storedHash

My only ideas to address the issue you bring up is to: 1. get Sven to change his design/coding behavior which may impede the functional improvement of Zinc in a small way. 2. get Pharo to behave as the blue book says it should 3. get Gemstone to behave like Pharo does. 4. Put an asSymbol everywhere the problem pops up. 5. ??? I'm sure there are better ideas but that's all I can think of at the moment. Also I do it twice in that method. I'd really appreciate reading a guide or some guidelines on how to do cross platform development. Or just code reviews like you've provided. I also override things rather than subclass in the port, as a rule. I think that's also offensive in some way but I'm not sure how/why. Thanks for the heads up Paul

Cheers, Esteban Ahh. I forgot there was one in the MetacelloRepository. It is outdated. Sorry. Use the config in http://www.squeaksource.com/ZincHTTPComponents After you load from the config will you load the latest Zinc-HTTP from SqueakSource? If so then reload the Zinc-Gemstone package afterwards and it should fix your issues. You may have to change the ZnNetworkingUtils classsocketStreamTimeout on your own as I don't think its in the Zinc-Gemstone package. As I mentioned to Phillipe, I don't have better ideas than to override methods where there are platform inconsistencies that need to be addressed for the stuff to load and run. Maybe you would be comfortable to add a version 1.2 to the Zinc config on squeaksource that pulls in the latest Zinc that Sven has made and then loads the Zinc-Gemstone package. If so please do. Good luck and let me know what else I can help with Paul

Re: [Pharo-project] [GS/SS Beta] zinc incompatibilities with gemstone
Hi Esteban - How are you loading Zinc into Gemstone? Were you using the metacello configuration on Squeaksource or something else? The reason I ask is all three issues you report were fixed/working at the start of June when I updated the port to what was current at the time. The Gemstone port is current up to Zinc-HTTP-SvenVanCaekenberghe.162 which is from May 19th. Let me know if loading via the metacello config is flawed and I'll update everything. Also check that you are loading version 1.1 of the project. It is the version referenced in #stable: I pasted the specific fixes below Thanks Paul ZnUrlscheme: symbol symbol isNil ifTrue: [ scheme := nil ] ifFalse: [ (#(http https) includes: symbol asSymbol) ifTrue: [ scheme := symbol asSymbol ] ifFalse: [ (ZnUnknowScheme scheme: symbol) signal ] ] ZnNetworkingUtilsisProxySet ^ HTTPSocket httpProxyServer isEmptyOrNil not ZnNetworkingUtils class socketStreamTimeout Timeout in seconds for SocketStream IO ^ 10
[Pharo-project] Monticello mcz files write their DataStream and a portion of their chunk-files as WideStrings, which are non-portable.
Hi-
I created an issue in the tracker:
https://code.google.com/p/pharo/issues/detail?id=2697
Some packages that were created with and load fine into Pharo 1.1
release do not load into Gemstone because of the use of WideStrings
while creating the mcz files. I don't know how to dissect the mcz files
at this time but in describing my issue on the GLASS list, Dale Henrichs
was able to reproduce the problem and diagnose it. His diagnosis is
pasted below.
To recreate my issue you must be using Gemstone 2.4.4.1, Glass
1.0-beta8.2, and GemTools for Gemstone 2.4.4. First load the
ConfigurationOfJQueryWidgetBox package from the Metacello Repository on
SqueakSource. Then run:
(ConfigurationOfJQueryWidgetBox project latestVersion)
load: #('JQWidgetBox-FullCalendar-Core').
It will attempt to load the package but complain that a dependency for
the JQFullCalendar Class is not met. The JQFullCalendar class is
provided by the JQWidgetBox-FullCalendar-Core package.
Our entire discussion leading up to his diagnosis is here:
http://forum.world.st/aFilePackage-cannot-perform-the-selector-preamble-with-the-arguments-in-anArray-aChangeRecord-td2291748.html#a2294376
Is there a way to write the mcz files using something other than
WideStrings that will allow me to attempt to load them into Gemstone and
perhaps get a different result?
Thanks
Paul
Paul,
Okay, it looks to me like your mcz file(s) are corrupted ... probably
due to a bug in Pharo 1.2 (that's the version you're using right?).
In an mcz file the snapshot of the definitions are serialized using two
formats:
1. a DataStream on an ordered collection of MCDefintions
2. a chunk-file formatted string.
It appears that for the DataStream, the entire(?) stream is written as a
WideString ... WideString is Squeak/Pharo dependent and is not portable
at all ... this is new. When GemStone hits the widestring an error is
thrown and Monticello tries to use the chunk-file format (which is why
you ran into the preamble probelm ... chunk file format is normally hit
(nor is it desirable to hit it)...
The chunk file-file is partially written as a WideString again...because
the WideString is not portable it breaks the parsing algorithms for
GemStone ... interestingly enough the chunk-file string looks to be a
WideString for the first hundred characters or so ...
One of three things is happening:
1. someone in Pharo land decided it was a good idea to create mcz
files using WideString
2. The that you used to create the class had a WideString in it
3. there is a bug somewhere in the pharo/monticello implementation
I can't guess which of those 3 the problem is and I can't guess what the
solution might be either.
If you bring up this bug on the Pharo list, I'll monitor the list and if
I can step in and help, I will.
Dale

Interesting. Now is the problem happening with other packages than a JS related? Stef / Hi- / Hi - Yes. If you attempt to load the latest Money package I uploaded to SqueakSource into Gemstone it fails because it requires the Currency class, which is provide by the Money package. The Money package doesn't use any JS. The Money package loads just fine into Pharo. It behaves in the same way as the JQWidgetBox-FullCalendar-Core package.
