PureZIP library : ZIP / UNZIP files

[Thorsten1867]

Thanks a lot!
I not really understand why, but your right.
Now it works perfect.

How to code when I need to compress a recursive folder (with PureZIP_AddFiles) which contains some files with accented characters?

PureZIP_AsciiDosLatinUS_To_AsciiWinLatin1 only transforms one string every time.

Yes, I can make ExamineDirectory (recursive) and transform one by one...but it's very heavy.. if we've some other option....

I am afraid you have to code your own recursive routine.

Not so heavy.
There is an example of recursive zipping (with relative paths) three posts above.

I might be wrong, but is it possible when using
this great zip library with the pngimage decoder,
you get the message:

POLINK: error: Symbol '_inflate_copyright'is myltiply defined......

[AL90]

POLINK: error: Symbol '_inflate_copyright'is myltiply defined......

Do you use PureZIP_AddFiles() ? With this command I get also some
problems in real TotalCommander. TC will give an error like Unknown Format if I want Delete a File in Archive.
But the Archive is not corrupt. All Files can be normal Extracting. Now I use
PureZIP_Archive_Compress() and it will work better. Also in TC are
now no longer problems.
Possibly a bug in PureZIP_AddFiles ? Currently I rewrite my Tool

Pure FileMaster

and will replace all AddFiles() with ArchiveCompress() for more
compatiblity in next version (v1.3)

Sorry for my bad English!

Note :
There is a known problem with PureZIP and the ImagePluginPNG purebasic library. If you use both in the same program, you will get a POLINK error "Symbol '_inflate_copyright' is multiply defined" because both use the ZLIB static library.
I don't know how to fix this.

Well, I'm also using TC (beta 3 at moment), and I've not any problem with PureZip, even deleting files from TC.
I'm using PureZIP_AddFiles()

Code: Select all

Procedure Zipear(zipf.s, param.s, recur.l)
  DeleteFile(zipf)
  nFi = PureZIP_AddFiles(zipf, param, #PureZIP_StorePathRelative, recur)
  WriteStringn(nFilog,"Comprimidos "+rset(str(nFi),6)+ " : "+GetFilePart(zipf))
EndProcedure

I've tested it now again, with my last night backups, and no problem...

@Max

I use wildcards like this:

PureZIP_AddFiles(ZipFile$,fm_tmp$+"*.*",2,2)

and archive contains which is created so will TC not delete.
Now I'm finish with rewrite my Procedures and I have replace
all PureZIP_AddFiles() to PureZIP_Archive_Compress().
Result: TC will no longer get any errors and all works fine.
I can't explain why it is so. BTW: I have use any older TC version (6.51)
not the latest.

BTW:

PureZIP_AddFiles() will get #Null if I e.g. add an Empty Directory and
PureZIP_Archive_Compress() will get -1. I'm not sure if it is normal.
But I think it is IMHO not correct?!

Probably because you are using #PureZIP_RecursiveZeroDirs (help file : 'recursive file search and add empty directories (use only if necessary)').
It's a trick to add empty dirs (wich the ZLIB library I use does not normally allow), so the ZIP structure may be a little 'weird' for some archivers. But while it does not allow archive modification, the extraction works.
Do you also have this problem with #PureZIP_Recursive ?

BTW:
PureZIP_AddFiles() will get #Null if I e.g. add an Empty Directory and
PureZIP_Archive_Compress() will get -1. I'm not sure if it is normal.

This is correct :
PureZIP_Archive_Compress() can't add a directory, it's for files, so you get an error.
Or the other hand, PureZIP_AddFiles() tolerates empty dirs, but an empty dir has no files in it, so it returns 0 (filecount).

[AL90]

Do you also have this problem with #PureZIP_Recursive ?

Yes. How I say I use Recursive. (See on Top) I have make a new test
with TC now and it the same problem:

ZIP-Archive is defekt or has a unknown format!

but (also complete) Extraction is possible without errors.
Yourself can test it with PFM v1.2. BTW: I have now successfully
converted all AddFiles() in ArchiveCompress() and all will now
work 100% without errors. (Also TC will work now without errors)
But I can't more exact explain this phänomen. Sorry.
I will release 1.3 in the next few days. If you want you can
test it then in combination with real TC.

This is correct :
PureZIP_Archive_Compress() can't add a directory, it's for files, so you get an error.
Or the other hand, PureZIP_AddFiles() tolerates empty dirs, but an empty dir has no files in it, so it returns 0 (filecount).

Ok I think I understand you now.

Yes. How I say I use Recursive.

In your example you use #PureZIP_RecursiveZeroDirs (2) and not #PureZIP_Recursive (1).

[AL90]

Yes, because I want add empty dirs. For my Tool I cannot ignore
selected EmptyDirs while copying. (same in real TC)

Hi at all.

I have a problem using this lib.
If I add an tga file, this file will be destroyed (inside the zip file and after decompressing). I can't use it after decompression.

Here's an example code:

Code: Select all

MyZip.s="C:\test\zip_test.zip"
MyZIPFile1.s="C:\Test\test_tga.tga"

If PureZIP_Archive_Create(MyZIP.s, #APPEND_STATUS_CREATE)
  Debug PureZIP_Archive_Compress(MyZIPFile1.s, #False)
  PureZIP_Archive_Close()
EndIf

Taken from the helpfile.

Here is the image: http://www.morty-productions.de/zip_bug/test_tga.tga

And here is an image showing my problem:


I use PB 4.00 running on Win XP Professional. Downloaded the latest version of the library.

Hope someone could help.

Greetz, Morty

PS: Sorry for my bad english.

Note that there is a bug in the PB4.00 file library.

Please upgrade to PB4.02 and test again.

Update (Both libs)

Changes :
- (de)compression callback [set with PureZIP_SetCompressionCallback(*ProcedureAddress)] : if the callback returns #True, the (de)compression stops and the function returns a #PureZIP_CallbackStop error.

Code: Select all

Returned value [only for PureZIP_Archive_Compress() and PureZIP_Archive_Extract()] :
#FALSE :  compression / extraction continues
#TRUE  :  compression / extraction stops !
          PureZIP_Archive_Compress() and PureZIP_Archive_Extract() returns #PureZIP_CallbackStop error
