Re: [Pharo-dev] What is wrong with Settings Browser ?

by Tudor Girba

Hi, No need to guess :). The main problem is that the System Browser is using PackageInfo instead of RPackage. Take a look at the analysis I did on this case (yes, I used some fancy tools): http://www.humane-assessment.com/blog/making-the-pharo-settings-browser-ope… Both the problem and the slice are documented here: https://pharo.fogbugz.com/f/cases/12897/System-Browser-is-slow-when-opened-… Cheers, Doru On Sat, Feb 15, 2014 at 8:27 PM, <luc.fabresse(a)gmail.com> wrote: > I guess (i do not know) that it relies on pragma and therefore it scans > the whole system > > Luc > > EnvoyÃ© de mon iPhone > > Le 15 fÃ©vr. 2014 Ã 07:51, jannik laval <jannik.laval(a)gmail.com> a Ã©crit : > > It means it opens only preferences related to this package. > > Jannik > > > 2014-02-15 0:07 GMT+01:00 Alexandre Bergel <alexandre.bergel(a)me.com>: > >> What does it mean to open a Setting Browser on a package? >> >> Alexandre >> >> >> On Feb 13, 2014, at 12:30 PM, jannik laval <jannik.laval(a)gmail.com> >> wrote: >> >> > Hi pharoers, >> > >> > I have a small problem with Settings Browser: when I open it on a >> single package settings, it is really slow. >> > >> > Just try it. >> > Opening a Settings browser is fast (213ms on my machine): >> > == >> > SettingBrowser new open >> > == >> > Now, with a specific package name, it is really slow (5284ms on my >> machine !!!): >> > == >> > SettingBrowser new setViewedPackageNames: 'Settings-Network'; open. >> > == >> > or this line: >> > == >> > SettingBrowser new changePackageSet: {PackageOrganizer default >> packageNamed: 'Settings-Network' ifAbsent:[]}; open. >> > == >> > >> > I don't understand what is wrong.

Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2014-02-28 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

NB and ASMJit questions

by Torsten Bergmann

Hi, I'm trying to mimic the following C/C++ example in NativeBoots to allow random number generation on windows: https://gist.github.com/kbjorklu/6317361 When I combine the flags in Pharo using "|" in the same way like in the first function call of the example: acquireContextExample1 NBFFICallout stdcall: #(BOOL CryptAcquireContextA(HCRYPTPROV self, 0, 0, PROV_RSA_FULL, CRYPT_VERIFYCONTEXT | CRYPT_SILENT)) module: #advapi32 I get an error 'comma expected'. Looks like the NBFnSpecParser does not allow expression evaluation like CRYPT_VERIFYCONTEXT | CRYPT_SILENT. Will this be possible in future versions? Nonetheless I tried to continue and since I defined: CRYPT_VERIFYCONTEXT := 16rF0000000. CRYPT_SILENT := 16r00000040. I evaluated manually and tried to use the harcoded value directly: acquireContextExample2 "Retrieves information about the current console font." <primitive: 'primitiveNativeCall' module: 'NativeBoostPlugin'> ^ NBFFICallout stdcall: #(BOOL CryptAcquireContextA(HCRYPTPROV self, 0, 0, PROV_RSA_FULL, 16rF0000040)) module: #advapi32 but this returns another error when converting using #asDWord: (16rF0000040 i4) exceeds doubleword (32bit) range in an AJImmediate but 16rF0000040. Looks like it is treated as unsiged since 16rF0000040 asUImm32 asDWord works. How to specifiy the number directly but as unsigned? To reproduce: - take a fresh Pharo3.0 Latest update: #30759 - load "OSWindows" from config browser to get the core and other packages - load "OS-Windows-Cryptography" package/mcz from smalltalkhub.com/#!/~OS/OS-Windows - evaluate WinCryptoProvider new acquireContextExample2 or WinCryptoProvider new acquireContextExample1 Any helping hand in converting the example would be appreciated. Thx T.

I would guess that you are already on the point of waiting for a server response, so you already successfully initialised networking, resolved DNS, opened a TCP socket and wrote the request over it. On the other hand, one of those steps might not have been done right, since you get no response. Any chance of a stack trace ? Or an image ? But that would be a headless one I guess ;-) Sven

Pharo 3 - Nautilus bug ?

When browsing class extensions, when I have an extension in instance side and an extension in class side, this class appears 2 times in the browser. See attached screenshot.

Connection closed while waiting for data in bootstrapped image

by Pavel Krivanek

Hi Sven, we can successfully load network packages to the bootstrapped image but when we try to test it using: ZnClient new get: 'http://zn.stfx.eu/zn/numbers.txt'. we get "ConnectionClosed: Connection closed while waiting for data" error after few seconds. Do you have some idea, what may be wrong? Probably something is not initialized well but I have no clue what. Cheers, -- Pavel
