PureZIP library : ZIP / UNZIP files

[gnozal]

Update
New function : PureZIP_SetArchivePassword() ; set current archive password for both compress and extract functions.

[gnozal]

Update
- PureZIP now uses ZLIB's crc32() instead of PB's CRC32FingerPrint()
- New ZLIB functions in PureZIP_W library
- Somes fixes with password and compress from memory

Sweet dude.. love this lib!

Update
- ZLIB static lib is now V1.2.3

Update information

zlib 1.2.3

July 18, 2005

Version 1.2.3 eliminates potential security vulnerabilities in zlib 1.2.1 and 1.2.2, so all users of those versions should upgrade immediately. The following important fixes are provided in zlib 1.2.3 over 1.2.1 and 1.2.2:
Eliminate a potential security vulnerability when decoding invalid compressed data
Eliminate a potential security vulnerability when decoding specially crafted compressed data
Fix a bug when decompressing dynamic blocks with no distance codes
Fix crc check bug in gzread() after gzungetc()
Do not return an error when using gzread() on an empty file

would be nice to get a ZIP-lib including with source to avoid the desaster with previous versions and compatibility.
just a suggestion

There will be no disaster :
- no source lost after a hard disk crash (I make backups) ;
- no version compatibility problem (if I loose interest in Purebasic, I will release all my lib sources like you or Danilo did).

i thought only that most of the stuff (ZLib) is already OpenSource or under a GPL.Don't know exactly if you wrote more than a wrapper.
Same also for BriefLZ, I released my wrapper to the public.

its your choice.

Thanks man..

I tried this:

Code: Select all

myzip.s = "test.zip"
myzipfile1.s = "t.mp3"
myzipfile2.s = "a.txt"



If PureZIP_Archive_Create(MyZIP.s, #APPEND_STATUS_CREATE)
  Debug PureZIP_Archive_Compress(MyZIPFile1.s, #FALSE)
  Debug PureZIP_Archive_Compress(MyZIPFile2.s, #FALSE)
  PureZIP_Archive_Close()
EndIf

And I get VERY interesting results..

From inside the IDE, works great.. if I compile out to an exe.. I get a
22 byte file..?

i thought only that most of the stuff (ZLib) is already OpenSource or under a GPL.Don't know exactly if you wrote more than a wrapper.

There are 3 libs :
- PureZIP_O : original ZLIB static lib
- PureZIP_W : wrapper to ZLIB static lib
- PureZIP_L : ZIP and UNZIP functions using PureZIP_W functions (not a wrapper, you have to use the basic ZLIB functions to build ZIP archive compatible functions)

From inside the IDE, works great.. if I compile out to an exe.. I get a 22 byte file..?

Yes, strange (never tested it like this, only in 'real' apps)...
With this I get a 22 byte file :

Code: Select all

myzip.s = "c:\purebasic393\program\PureZIP-test.zip" 
myzipfile1.s = "C:\PureBasic393\Program\PureCOLOR_TEST_2.pb" 
myzipfile2.s = "C:\PureBasic393\Program\PureCOLOR_TEST_3.pb" If PureZIP_Archive_Create(myzip.s, #APPEND_STATUS_CREATE) 
  PureZIP_Archive_Compress(myzipfile1.s, #False)
  PureZIP_Archive_Compress(myzipfile2.s, #False)
  PureZIP_Archive_Close() 
EndIf

But this works (CON exe) :

Code: Select all

myzip.s = "c:\purebasic393\program\PureZIP-test.zip" 
myzipfile1.s = "C:\PureBasic393\Program\PureCOLOR_TEST_2.pb" 
myzipfile2.s = "C:\PureBasic393\Program\PureCOLOR_TEST_3.pb" 
OpenConsole()
If PureZIP_Archive_Create(myzip.s, #APPEND_STATUS_CREATE) 
  PureZIP_Archive_Compress(myzipfile1.s, #False)
  PureZIP_Archive_Compress(myzipfile2.s, #False)
  PureZIP_Archive_Close() 
EndIf
CloseConsole()

And this works (GUI exe):

Code: Select all

myzip.s = "c:\purebasic393\program\PureZIP-test.zip" 
myzipfile1.s = "C:\PureBasic393\Program\PureCOLOR_TEST_2.pb" 
myzipfile2.s = "C:\PureBasic393\Program\PureCOLOR_TEST_3.pb" 
If OpenWindow(0,0,0,0,0,0,"")
  If PureZIP_Archive_Create(myzip.s, #APPEND_STATUS_CREATE) 
    PureZIP_Archive_Compress(myzipfile1.s, #False)
    PureZIP_Archive_Compress(myzipfile2.s, #False)
    PureZIP_Archive_Close() 
  EndIf
EndIf

So it works, but not without console or window ; I don't know why ...

@gnozal
Thanks a lot for your hard Work!!!!!!!

I am working under Windows XP and PB 3.93.

The Memorycompress example works fine.

The PureZIP_Archive_Create() command seems to be OK.

But if i try to Compile with PureZIP_Archive_Compress(), i get this error:


The flags are always the same.

Please write the explanaition in all your helpfiles:

There are 3 libs :
- PureZIP_O : original ZLIB static lib
- PureZIP_W : wrapper to ZLIB static lib
- PureZIP_L : ZIP and UNZIP functions using PureZIP_W functions (not a wrapper, you have to use the basic ZLIB functions to build ZIP archive compatible functions)

It took me a long time to find out what is what.
I thought PureZIP_W stands for Windows and PureZIP_L for Linux....

[dagcrack]

Shouldnt PureZIP_L be called PureZIP_F ? (for: Functions)...
Doesnt seem like he likes to gift his sources - which is ok, but however hes giving the libs for free why you ask for more? You people... always trying to suck as much as possible from others!!!

Could you provide some code please ?

Well, it's L for library

Doesnt seem like he likes to gift his sources - which is ok, but however hes giving the libs for free why you ask for more? You people... always trying to suck as much as possible from others!!!

I could add a sentence like Fangbeast : "As with all my apps, use this if you like it, don't use it if you don't like it. Suggestions on how to improve, bug reports are welcome. Stupid comments, criticisms, arrogant gum flapping etc, are not."

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.
