PureBasic 5.40 beta 1 est disponible sur votre compte

Starting with 5.40, we changed the way of importing API functions (now it's much more robust and flexible), so we need to have strong typing of every args (especially strings). If you encounter one API call which is incorrectly declared, just paste it here and we will fix it.

La façon d'importer les fonctions de l'API change à partir de la 5.40. Le typage est plus strict que dans les versions précédentes, aussi si vous constatez que la déclaration d'une fonction n'est pas correcte, n'hésitez pas à signaler le problème ici pour qu'il soit corrigé.

Explications de Fred pour utiliser la biblio CGI :

To test CGI on Windows, I installed "easyphp" http://www.easyphp.org/ , which install all needed tools, then added this to the apache conf file:

Code :

Sélectionner tout

ProxyPass /testfcgi/ fcgi://localhost:5600/

and uncommented the lines:

Code :

Sélectionner tout

1
2
3
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

Once restarted, apache should redirect the url http://localhost/testfcgi to the port 5600

Then compile the example found in WaitFastCGIRequest() doc and it should work.

On linux, you need to do the same (installing apache and enabling mod proxy fastcgi)

Un utilisateur a comparé les différents formats de compression disponibles avec la 5.40, voici son test et ses résultats :

Purebasic spoils us with 5 different built-in compression codecs (6 if you count the uncompressed bundling of TAR, or 7 if you count the deprecated x86-only JCALG1)
These are: ZIP, LZMA, BriefLZ, TAR.GZip, and TAR.BZip2 (ps. Fred it would be nice if BZIP2 and GZIP were available on their own, rather than having to use TAR bundling! TAR is ewww but BZIP2 is awesome!)

So here's a simple test program to help find out which of Purebasic's built-in packers is best suited to the data we want to compress/decompress.

The variables are PACK TIME, UNPACK TIME, PACK SIZE/RATIO, and PB EXE SIZE. Each packer of course has its own strengths and weaknesses!

Here's the results of a 91 megabyte SQL dump (UTF8 textfile). Tested with Purebasic x86 5.40 LTS in Windows XP. I havent had a chance to do x64 test.
I ran each test twice and only recorded the 2nd result to ensure 'even caching':

                ZIP        LZMA       BriefLZ    TAR        TAR.GZ     TAR.BZ2       "Winning" order (TAR excluded):
                --------------------------------------------------------------       ----------------
PACK TIME       3175ms     67647ms    1653ms     1141ms     3325ms     9464ms        BriefLZ, ZIP, TAR.GZ, TAR.BZ2, LZMA
UNPACK TIME     1532ms     2254ms     2273ms     1252ms     1332ms     3145ms        TAR.GZ, ZIP, LZMA, BriefLZ, TAR.BZ2
PACK SIZE       25218579   18887882   34247532   94030848   25218522   19782588     
PACK RATIO      26.820%    20.087%    36.422%    100.002%   26.820%    21.039%       LZMA, TAR.BZ2, TAR.GZ, ZIP, BriefLZ
PB.EXE SIZE     207,872    291,328    15,872     219,648    219,648    219,648       BriefLZ, ZIP, TAR.GZ/TAR.BZ2, LZMA

So, from this one test with this dataset, we can summarize:
ZIP: A great balance of compression and speed.
LZMA: Extremely slow compression, but thats the price you pay for the very best compression ratio.
BriefLZ: Extremely good performance in both packing & unpacking, and the resulting exe is still TINY unlike the others. 36% compression to ZIPs 26% means it's not great, but still pretty good.
TAR.GZ: On par with ZIP.
TAR.BZ2: Compression ratio so very close to LZMA yet compression speed is 7x faster. Decompression 1.4x slower than LZMA however.

Quite a nice menu to choose from, depending on ours projects individual needs

One of the nice surprises I found was that the BriefLZ codec only adds 10kb to the exe - thats with full compress + decompress support! And its speed of both is very good, especially compression but still respectable decompress speed. Its compression ratio is also quite respectable too, compressing my 91mb sample file to 36%. Compared to ZIPs 27% its not great but still pretty good, and overall I think it makes an excellent packer for executable resources!

Fred vient de mettre en place un WebSVN pour consulter les fichiers de la doc sans Subversion.

I just setup a WebSVN to browse the public PureBasic SVN:

http://svn.purebasic.fr:8080/websvn

You can find all the Windows API imports in Imports/Windows

C'est utile pour ceux qui veulent contribuer à l'amélioration des déclarations des fonctions API, voir l'exemple de ts-soft ci-dessous :

J'ai laissé passer quelques bêtas, nous en sommes à la beta 7, elle est disponible sur votre compte.

Hello folks,

Beta 7 is out and should bring more fixes, especially on OS X. Have fun !

OK, the quick fix was half baked, so hopefully beta 6 will solve it completely. Happy testing !

Beta 5 is out and only fix one bug with API and string concatenation (which could prevent further testing). On a side note, we have signed the OS X apps since the 5.40 beta, can OS X users tests if it works with gatekeeper activated ? The IDE should open after displaying a warning message without changing the default security features.

Beta 4 is available ! It should include many bug fixes since beta 3. Also some minor additions:

- Added: #Empty$ constant
- Added: #PB_ByteLength support to MemoryStringLength()

- Changed: The DotPath(), DashPath() & CustomDashPath() commands now have an optional 'StartOffset' parameter
- Changed: The 'Distance' parameter of DotPath() has been changed: It now refers to the distance between the center of each dot (not the space between the dots)
