# Build (GitHub) — pipeline CI primaria

# - GitHub esegue TUTTA la CI (Gitea non esegue Actions)

# Trigger:

||||||
|
|
||||||
|
| Opzione | Default | Descrizione |
|
||||||
|
|---------|---------|-------------|

|
||||||
|
## Release Workflow
|
||||||
|
|
||||||
|
Le release sono automatiche via tag Git:
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
# 1. Aggiorna VERSION e CHANGELOG.md
|
||||||
|
echo "1.7.0" > VERSION
|
||||||
|
# (modifica CHANGELOG.md spostando entry da [Unreleased] a [1.7.0])
|
||||||
|
|
||||||
|
# 2. Commit
|
||||||
|
git add VERSION CHANGELOG.md
|
||||||
|
git commit -m "chore(release): v1.7.0"
|
||||||
|
|
||||||
|
# 3. Tag annotato
|
||||||
|
git tag -a v1.7.0 -m "Release v1.7.0"
|
||||||
|
|
||||||
|
# 4. Push
|
||||||
|
git push origin main
|
||||||
|
git push origin v1.7.0
|
||||||
|
```
|
||||||
|
|
||||||
|
Il workflow `.github/workflows/release.yml` compilerà tutte le architetture
|
||||||
|
e creerà la release su Gitea con gli artifact ZIP allegati. Il mirror GitHub
|
||||||
|
riceverà automaticamente il tag.
|
||||||
|
|
||||||
|
## Code Style
|
||||||
|
|
||||||
|
- C/C++: stile coerente con il file modificato
|
||||||
|
- Python: PEP 8 (4 spazi indent, line length flessibile)
|
||||||
|
- Header file: `#include` ordinati: stdlib → Win32 → progetto
|
||||||
|
- Encoding: UTF-8 senza BOM (eccetto `.rc` che richiede UTF-16 LE)
|
||||||
|
- Line endings: LF in repo (`.gitattributes` normalizza)
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
```powershell
|
||||||
|
# Recommended: zlib 1.3 with auto-detected toolset
|
||||||
|
python build_plugin.py
|
||||||
|
|
||||||
|
# Select zlib version (1.1.3 = legacy, 1.3 = default)
|
||||||
|
python build_plugin.py --zlib-version 1.1.3
|
||||||
|
|
||||||
|
# Specific toolset (2022|2026|auto)
|
||||||
|
python build_plugin.py --toolset 2022
|
||||||
|
|
||||||
|
# Print version and exit
|

|
||||||
|
|
||||||
|
## Hardening
|
||||||
|
|
||||||
|
Questo plugin gira con i permessi del processo NSIS chiamante (tipicamente
|
||||||
|
l'utente che esegue l'installer). Non richiede privilegi elevati per la
|
||||||
|
compilazione né per l'esecuzione, salvo dove esplicitamente documentato.
|
||||||
|
|
||||||
|
DLL distribuite tramite Releases sono compilate da CI GitHub Actions con
|
||||||
|
toolchain pinnata. Verificare hash SHA256 pubblicati nelle release.

<h1>nsisunz</h1>

|
||||||
|
<h2>Introduction</h2>
|
||||||
|
<p><b>nsisunz</b> is a NSIS plugin which allows you to extract files from ZIP
|
||||||
|
archives.</p>
|
||||||
|
<p><b>nsisunz</b> is great when you use another NSIS plug-in named
|
||||||
|
<em>NSISdl</em> to download a ZIP file from the internet.
|
||||||
|
Download a small installer which lets the user choose the components he/she
|
||||||
|
want to install and the installer downloads it (<em>QuickTime Setup</em> does
|
||||||
|
this).</p>
|
||||||
|
<p>Note:
|
||||||
|
<em>nsisunz</em> does not support password protected ZIP archives
|
||||||
|
(encrypted).<br/>
|
||||||
|
To extract only a specific file from the archive use the
|
||||||
|
<a href="#fileopt">"/file"</a> option.
|
||||||
|
</p>
|
||||||
|
<h2>How to use</h2>
|
||||||
|
<h3>Setting it up</h3>
|
||||||
|
<p>To see a great example of how to use the plug-in,
|
||||||
|
check out the included <a href="example.nsi">example script</a>.</p>
|
||||||
|
<p>You use the <em>Unzip</em>, <em>UnzipToLog</em> or the
|
||||||
|
<em><a href="#UnzipToStack">UnzipToStack</a></em> function to extract files
|
||||||
|
from a ZIP archive.</p>
|
||||||
|
<p>In my opinion the best way to describe things is by showing an example,
|
||||||
|
so here is one:</p>
|
||||||
|
<pre>
|
||||||
|
<font class="keyword">InitPluginsDir</font>
|
||||||
|
<font class="comment">; Call plug-in. Push filename to ZIP first, and the dest. folder last.</font>
|
||||||
|
nsisunz::UnzipToLog <font class="string">"$PLUGINSDIR\myzipfile.zip" "$INSTDIR"</font>
|
||||||
|
|
||||||
|
<font class="comment">; Always check result on stack</font>
|
||||||
|
<font class="keyword">Pop</font> $0
|
||||||
|
<font class="keyword">StrCmp</font> $0 <font class="string">"success"</font> ok
|
||||||
|
<font class="keyword">DetailPrint</font> <font class="string">"$0"</font> <font class="comment">;print error message to log</font>
|
||||||
|
ok:
|
||||||
|
|
||||||
|
<font class="comment">; You can also use the "Unzip" function if you don't want to use the log.
|
||||||
|
; It is a lot quicker, and is preferred for large ZIP archives.</font>
|
||||||
|
nsisunz::Unzip <font class="string">"$PLUGINSDIR\myzipfile.zip" "$INSTDIR"</font>
|
||||||
|
</pre>
|
||||||
|
<a name="UnzipToStack"><h3>The UnzipToStack function</h3></a>
|
||||||
|
<p>The <em>UnzipToStack</em> function can be used instead of the <em>UnzipToLog</em> function
|
||||||
|
if you want the extraction to be a lot faster when extracting from very large ZIP archives and still
|
||||||
|
want to see the files extracted. This is how you use it:
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
nsisunz::UnzipToStack <font class="string">"$PLUGINSDIR\myzipfile.zip" "$INSTDIR"</font>
|
||||||
|
<font class="keyword">Pop</font> $0
|
||||||
|
<font class="keyword">StrCmp</font> $0 <font class="string">"success"</font> ok
|
||||||
|
<font class="keyword">DetailPrint</font> <font class="keyword">"$0"</font> <font class="comment">;print error message to log</font>
|
||||||
|
<font class="keyword">Goto</font> skiplist
|
||||||
|
ok:
|
||||||
|
|
||||||
|
<font class="comment">; Print out list of files extracted to log</font>
|
||||||
|
next:
|
||||||
|
<font class="keyword">Pop</font> $0
|
||||||
|
<font class="keyword">DetailPrint</font> $0
|
||||||
|
<font class="keyword">StrCmp</font> $0 "" 0 next <font class="comment">; pop strings until a blank one arrives</font>
|
||||||
|
|
||||||
|
skiplist:
|
||||||
|
</pre>
|
||||||
|
<a name="fileopt"><h3>Extracting specific files</h3></a>
|
||||||
|
<p>
|
||||||
|
To extract only a specific file use the "/file" option like this:
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
nsisunz::UnzipToLog /file <font class="string">"AnyPathInsideZIP/AFile.txt" "myzip.zip" "c:\myfiles"</font>
|
||||||
|
</pre>
|
||||||
|
<p>
|
||||||
|
The path is relative to the root of the ZIP archive so you don't have to
|
||||||
|
prepend a slash ("/"). Furthermore the foldernames are extracted with the file so
|
||||||
|
the example above creates a file named "c:\myfiles\AnyPathInsideZIP\AFile.txt".
|
||||||
|
To avoid this use "/noextractpath" like this:
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
nsisunz::UnzipToLog /noextractpath /file \
|
||||||
|
<font class="string">"AnyPathInsideZIP/AFile.txt" "myzip.zip" "c:\myfiles"</font>
|
||||||
|
</pre>
|
||||||
|
<h3>Using nsisunz with NSISdl</h3>
|
||||||
|
<p>To use <em>NSISdl</em> with <em>nsisunz</em> to download and extract a ZIP archive,
|
||||||
|
do something like this:</p>
|
||||||
|
<pre>
|
||||||
|
<font class="keyword">InitPluginsDir</font>
|
||||||
|
NSISdl::download <font class="string">http://www.domain.com/file "$PLUGINSDIR\localfile.zip"</font>
|
||||||
|
<font class="keyword">Pop</font> $R0 ;Get the return value
|
||||||
|
<font class="keyword">StrCmp</font> $R0 <font class="string">"success"</font> +3
|
||||||
|
<font class="keyword">MessageBox</font> <font class="param">MB_OK</font> <font class="string">"Download failed: $R0"</font>
|
||||||
|
<font class="keyword">Quit</font>
|
||||||
|
|
||||||
|
nsisunz::UnzipToLog <font class="string">"$PLUGINSDIR\localfile.zip" "$INSTDIR"</font>
|
||||||
|
<font class="keyword">Pop</font> $R0
|
||||||
|
<font class="keyword">StrCmp</font> $R0 <font class="string">"success"</font> +2
|
||||||
|
<font class="keyword">DetailPrint</font> <font class="string">"$R0"</font> <font class="comment">;print error message to log</font>
|
||||||
|
|
||||||
|
</pre>
|
||||||
|
<h3>Options</h3>
|
||||||
|
<p>These are the optional parameters you can specify when calling <em>nsisunz</em>.</p>
|
||||||
|
<table class="subtable">
|
||||||
|
<tr>
|
||||||
|
<td class="lefttable">/noextractpath</td>
|
||||||
|
<td class="righttable">This option makes the plug-in extract all files to
|
||||||
|
the destination directory without regard to paths stored in ZIP file.
|
||||||
|
Is often used in conjunction with "/file" to extract a single file
|
||||||
|
from anywhere in an archive to a destination directory.</td>
|
||||||
|
</tr>
|
||||||
|
<tr>
|
||||||
|
<td class="lefttable">/file</td>
|
||||||
|
<td class="righttable">Extract a specific file. Filename must be specified
|
||||||
|
as next parameter and must match a file in the ZIP including any
|
||||||
|
subdirectories. If the file couldn't be found in the ZIP file,
|
||||||
|
<em>nsisunz</em> pushes the string "File not found in ZIP file" on the
|
||||||
|
stack.</td>
|
||||||
|
</tr>
|
||||||
|
<tr>
|
||||||
|
<td class="lefttable">/text</td>
|
||||||
|
<td class="righttable">Sets the format of the text used in the log to the
|
||||||
|
next param. <em>"%f"</em> is replaced with the filename, <em>"%c"</em> is
|
||||||
|
replaced with the compressed size and <em>"%u"</em> is replaced with the
|
||||||
|
uncompressed size.
|
||||||
|
</td>
|
||||||
|
</tr>
|
||||||
|
</table>
|
||||||
|
<h3>Return value</h3>
|
||||||
|
<p>After you have called the DLL, <b>nsisunz</b> adds either "success" or a specific error message
|
||||||
|
on the stack. This is the possible error messages:</p>
|
||||||
|
<ul>
|
||||||
|
<li>Error opening ZIP file</li>
|
||||||
|
<li>Error opening output file(s)</li>
|
||||||
|
<li>Error writing output file(s)</li>
|
||||||
|
<li>Error extracting from ZIP file</li>
|
||||||
|
<li>File not found in ZIP file</li>
|
||||||
|
</ul>
|
||||||
|
<p>Usually, you don't need to check this value, but you still have to remove it from the stack
|
||||||
|
(have a look at the example above).</p>
|
||||||
|
<h2>Reserve files</h2>
|
||||||
|
<p>If you are using BZIP2 (solid) compression, it's important that files which are being extracted
|
||||||
|
in init- or page functions function are located before other files in the data block, because this
|
||||||
|
will make your installer faster.</p>
|
||||||
|
<p>If there are File commands in your sections or functions above the init- or page functions, add
|
||||||
|
ReserveFile commands above your sections and functions:</p>
|
||||||
|
<pre>
|
||||||
|
<font class="keyword">ReserveFile</font> <font class="string">"myzipfile.zip"</font>
|
||||||
|
<font class="keyword">ReserveFile</font> <font class="string">"${NSISDIR}\Plugins\nsisunz.dll"</font>
|
||||||
|
</pre>
|
||||||
|
<h2>Localization</h2>
|
||||||
|
<p>Use the <em>"/text"</em> parameter to localize the text used by nsisunz
|
||||||
|
for the log output.
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
<font class="comment">; Localized strings for use with nsisunz</font>
|
||||||
|
<font class="comment">; The "%f" in the string is replaced with the filename on run-time.</font>
|
||||||
|
<font class="comment">; "%c" and "%u" is replaced with compressed size and</font>
|
||||||
|
<font class="comment">; uncompressed size respectively. See example script.</font>
|
||||||

<h2>Notes</h2>
|
||||||
|
<p>
|
||||||
|
The plug-in is compressed with UPX to make it smaller.<br />
|
||||||
|
If you make changes to the source, re-compile and use UPX you may get this
|
||||||
|
message:<br />
|
||||||
|
<code>upx: nsisunz.dll: CantPackException: file is possibly packed/protected
|
||||||
|
(try --force)</code><br />
|
||||||
|
I used the "<code>--force</code>" parameter as proposed,
|
||||||
|
and without problems UPX reduced the size of <em>nsisunz.dll</em> from ~71 kb
|
||||||
|
to 31,5 kb<br/>
|
||||||
|
The reason for why you get this message is that the source #include's
|
||||||
|
"AggressiveOptimize.h" which makes the linker merge the code sections of the
|
||||||
|
final executable. This makes UPX think it's already packed (which it kinda is).
|
||||||
|
But by using the "<code>--force</code>" parameter, UPX may shrink it a lot
|
||||||
|
more.<br/>
|
||||||
|
I hope people appreciate my struggles to keep the size of the plug-in small.
|
||||||
|
If someone have any suggestions for making it even smaller I would like if
|
||||||
|
someone sendt me an e-mail.

# nsisunz NSIS Plugin
|
||||||
|
|
||||||
|
**Versione personale modificata**
|
||||||
|
|
||||||
|
Basato su [past-due/nsisunz](https://github.com/past-due/nsisunz) - un plugin NSIS per estrarre file da archivi ZIP.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Descrizione Originale
|
||||||
|
|
||||||
|
**nsisunz** è un plugin [NSIS](https://en.wikipedia.org/wiki/Nullsoft_Scriptable_Install_System) che permette di estrarre file da archivi ZIP.
|
||||||
|
|
||||||
|
> **nsisunz** è ideale quando si usa un altro plugin NSIS chiamato _NSISdl_ per scaricare un file ZIP da internet. Si può creare un piccolo installer che permette all'utente di scegliere i componenti da installare e l'installer li scarica.
|
||||||
|
|
||||||
|
### Origini e Storia
|
||||||
|
|
||||||
|
- _nsisunz_ è stato originariamente scritto da Saivert (http://saivert.com/)
|
||||||
|
- Supporto NSIS Unicode [aggiunto da Gringoloco023](http://portableapps.com/node/21879), Febbraio 2010
|
||||||
|
- Ulteriori miglioramenti di past-due, 2018+:
|
||||||
|
- Aggiornamento NSIS plugin API a 3.0
|
||||||
|
- Aggiornamento [zlib](https://zlib.net) a [1.2.11](https://zlib.net/ChangeLog.txt)
|
||||||
|
- Aggiornamento Minizip a 1.1-8
|
||||||
|
- Supporto build [CMake](https://cmake.org) (compila sia DLL ANSI che Unicode)
|
||||||
|
|
||||||
|
## Funzioni
|
||||||
|
|
||||||
|
### UnzipToLog
|
||||||
|
|
||||||
|
Estrae i file e mostra il log dettagliato:
|
||||||
|
|
||||||
|
```nsis
|
||||||
|
InitPluginsDir
|
||||||
|
; Chiama il plugin. Prima il file ZIP, poi la cartella di destinazione.
|
||||||
|
nsisunz::UnzipToLog "$PLUGINSDIR\myzipfile.zip" "$INSTDIR"
|
||||||
|
|
||||||
|
; Controlla sempre il risultato sullo stack
|
||||||
|
Pop $0
|
||||||
|
StrCmp $0 "success" ok
|
||||||
|
DetailPrint "$0" ; stampa messaggio di errore nel log
|
||||||
|
ok:
|
||||||
|
```
|
||||||
|
|
||||||
|
### Unzip
|
||||||
|
|
||||||
|
Estrazione veloce senza log (preferita per archivi grandi):
|
||||||
|
|
||||||
|
```nsis
|
||||||
|
nsisunz::Unzip "$PLUGINSDIR\myzipfile.zip" "$INSTDIR"
|
||||||
|
```
|
||||||
|
|
||||||

## ⚠️ Differenze nella versione personale
|
||||||
|
|
||||||
|
Questa versione è basata su [past-due/nsisunz](https://github.com/past-due/nsisunz) con le seguenti modifiche:
|
||||||
|
|
||||||
|
### Nuova architettura supportata: x64 (amd64-unicode)
|
||||||
|
|
||||||
|
L'originale supporta:
|
||||||
|
- x86-ansi
|
||||||
|
- x86-unicode
|
||||||
|
|
||||||
|
La versione personale aggiunge il supporto per:
|
||||||
|
- **amd64-unicode** (x64)
|
||||||
|
|
||||||
|
### Progetto Visual Studio
|
||||||
|
|
||||||
|
L'originale usa CMake per la compilazione. La versione personale include progetti Visual Studio:
|
||||||
|
- `Source/nsisunz.vcproj` - Progetto VS2008 (legacy)
|
||||||
|
- `Source/nsisunz.vcxproj` - Progetto VS2022 (x86-ansi, x86-unicode, amd64-unicode)
|
||||||
|
|
||||||
|
### File modificati/semplificati
|
||||||
|
|
||||||
|
La versione personale usa una versione più vecchia e semplificata di zlib:
|
||||||
|
- `Source/zlib/` - Libreria zlib semplificata (solo file essenziali per decompressione)
|
||||||
|
|
||||||
|
Rispetto all'originale GitHub che include:
|
||||||
|
- CMakeLists.txt e configurazione CMake completa
|
||||||
|
- zlib 1.2.11 completa con tutti i contributi (285 file)
|
||||||
|
- Minizip completo
|
||||||
|
- Configurazione CI/CD (.github, appveyor)
|
||||||
|
|
||||||
|
### File aggiunti
|
||||||
|
|
||||||
|
- `build_plugin.py` - Script Python per compilare il plugin per tutte le architetture
|
||||||
|
- `Doc/` - Documentazione (info.rtf, nsisunz_readme.html)
|
||||||
|
- `ExDLL/exdll.h` - Header per l'API NSIS extern DLL
|
||||||
|
|
||||||
|
### Compilazione
|
||||||
|
|
||||||
|
```cmd
|
||||||
|
cd nsUnz
|
||||||
|
python build_plugin.py
|
||||||
|
```
|
||||||
|
|
||||||
|
I DLL vengono copiati in `plugins/{platform}/nsisunz.dll`.

// This header file will kick in settings for Visual C++ 5 and 6 that will (usually)
|
||||||
|
// result in smaller exe's.
|
||||||
|
// The "trick" is to tell the compiler to not pad out the function calls; this is done
|
||||||
|
// by not using the /O1 or /O2 option - if you do, you implicitly use /Gy, which pads
|
||||||
|
// out each and every function call. In one single 500k dll, I managed to cut out 120k
|
||||||
|
// by this alone!
|
||||||
|
// The other two "tricks" are telling the Linker to merge all data-type segments together
|
||||||
|
// in the exe file. The relocation, read-only (constants) data, and code section (.text)
|
||||||
|
// sections can almost always be merged. Each section merged can save 4k in exe space,
|
||||||
|
// since each section is padded out to 4k chunks. This is very noticeable with smaller
|
||||||
|
// exes, since you could have only 700 bytes of data, 300 bytes of code, 94 bytes of
|
||||||
|
// strings - padded out, this could be 12k of runtime, for 1094 bytes of stuff! For larger
|
||||||
|
// programs, this is less overall, but can save at least 4k.
|
||||||
|
// Note that if you're using MFC static or some other 3rd party libs, you may get poor
|
||||||
|
// results with merging the readonly (.rdata) section - the exe may grow larger.
|
||||||
|
// To use this feature, define _MERGE_DATA_ in your project or before this header is used.
|
||||||
|
// With Visual C++ 5, the program uses a file alignment of 512 bytes, which results
|
||||||
|
// in a small exe. Under VC6, the program instead uses 4k, which is the same as the
|
||||||
|
// section size. The reason (from what I understand) is that 4k is the chunk size of
|
||||||
|
// the virtual memory manager, and that WinAlign (an end-user tuning tool for Win98)
|
||||||
|
// will re-align the programs on this boundary. The problem with this is that all of
|
||||||
|
// Microsoft's system exes and dlls are *NOT* tuned like this, and using 4k causes serious
|

|
// exe bloat. Very noticeable for smaller programs.
|
||||||
|
// The "trick" for this is to use the undocumented FILEALIGN linker parm to change the
|
||||||
|
// padding from 4k to 1/2k, which results in a much smaller exe - anywhere from 20%-75%
|
||||||
|
// depending on the size. Note that this is the same as using /OPT:NOWIN98, which *is*
|
||||||
|
// a previously documented switch, but was left out of the docs for some reason in VC6 and
|
||||||
|
// all of the current MSDN's - see KB:Q235956 for more information.
|
||||||
|
// Microsoft does say that using the 4k alignment will "speed up process loading",
|
||||||
|
// but I've been unable to notice a difference, even on my P180, with a very large (4meg) exe.
|
||||||
|
// Please note, however, that this will probably not change the size of the COMPRESSED
|
||||||
|
// file (either in a .zip file or in an install archive), since this 4k is all zeroes and
|
||||||
|
// gets compressed away.
|
||||||
|
// Also, the /ALIGN:4096 switch will "magically" do the same thing, even though this is the
|
||||||
|
// default setting for this switch. Apparently this sets the same values as the above two
|
||||||
|
// switches do. We do not use this in this header, since it smacks of a bug and not a feature.

Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:
|
||||||
|
x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
|
||||||
|
|
||||||
|
Polynomials over GF(2) are represented in binary, one bit per coefficient,
|
||||||
|
with the lowest powers in the most significant bit. Then adding polynomials
|
||||||
|
is just exclusive-or, and multiplying a polynomial by x is a right shift by
|
||||||
|
one. If we call the above polynomial p, and represent a byte as the
|
||||||
|
polynomial q, also with the lowest power in the most significant bit (so the
|
||||||
|
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
|
||||||
|
where a mod b means the remainder after dividing a by b.
|
||||||
|
|
||||||
|
This calculation is done using the shift-register method of multiplying and
|
||||||
|
taking the remainder. The register is initialized to zero, and for each
|
||||||
|
incoming bit, x^32 is added mod p to the register if the bit is a one (where
|
||||||
|
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
|
||||||
|
x (which is shifting right by one and adding x^32 mod p if the bit shifted
|
||||||
|
out is a one). We start with the highest power (least significant bit) of
|
||||||
|
q and repeat for all eight bits of q.
|
||||||
|
|
||||||
|
The table is simply the CRC of all possible eight bit values. This is all
|
||||||
|
the information needed to generate CRC's on data a byte at a time for all
|
||||||
|
combinations of CRC register values and incoming bytes.

/*

Notes beyond the 1.93a appnote.txt:
|
||||||
|
|
||||||
|
1. Distance pointers never point before the beginning of the output
|
||||||
|
stream.
|
||||||
|
2. Distance pointers can point back across blocks, up to 32k away.
|
||||||
|
3. There is an implied maximum of 7 bits for the bit length table and
|
||||||
|
15 bits for the actual data.
|
||||||
|
4. If only one code exists, then it is encoded using one bit. (Zero
|
||||||
|
would be more efficient, but perhaps a little confusing.) If two
|
||||||
|
codes exist, they are coded using one bit each (0 and 1).
|
||||||
|
5. There is no way of sending zero distance codes--a dummy must be
|
||||||
|
sent if there are none. (History: a pre 2.0 version of PKZIP would
|
||||||
|
store blocks with no distance codes, but this was discovered to be
|
||||||
|
too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
|
||||||
|
zero distance codes, which is sent as one code of zero bits in
|
||||||
|
length.
|
||||||
|
6. There are up to 286 literal/length codes. Code 256 represents the
|
||||||
|
end-of-block. Note however that the static length tree defines
|
||||||
|
288 codes just to fill out the Huffman codes. Codes 286 and 287
|
||||||
|
cannot be used though, since there is no length base or extra bits
|
||||||
|
defined for them. Similarily, there are up to 30 distance codes.
|
||||||
|
However, static trees define 32 codes (all 5 bits) to fill out the
|
||||||
|
Huffman codes, but the last two had better not show up in the data.
|
||||||
|
7. Unzip can check dynamic Huffman blocks for complete code sets.
|
||||||
|
The exception is that a single code would not be complete (see #4).
|
||||||
|
8. The five bits following the block type is really the number of
|
||||||
|
literal codes sent minus 257.
|
||||||
|
9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
|
||||||
|
(1+6+6). Therefore, to output three times the length, you output
|
||||||
|
three codes (1+1+1), whereas to output four times the same length,
|
||||||
|
you only need two codes (1+3). Hmm.
|
||||||
|
10. In the tree reconstruction algorithm, Code = Code + Increment
|
||||||
|
only if BitLength(i) is not zero. (Pretty obvious.)
|
||||||
|
11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
|
||||||
|
12. Note: length code 284 can represent 227-258, but length code 285
|
||||||
|
really is 258. The last length deserves its own, short code
|
||||||
|
since it gets used a lot in very redundant files. The length
|
||||||
|
258 is special since 258 - 3 (the min match length) is 255.
|
||||||
|
13. The literal/length and distance code bit lengths are read as a
|
||||||
|
single stream of lengths. It is possible (and advantageous) for
|
||||||
|
a repeat code (16, 17, or 18) to go across the boundary between
|
||||||
|
the two sets of lengths.

/*
|
||||||
|
Huffman code decoding is performed using a multi-level table lookup.
|
||||||
|
The fastest way to decode is to simply build a lookup table whose
|
||||||
|
size is determined by the longest code. However, the time it takes
|
||||||
|
to build this table can also be a factor if the data being decoded
|
||||||
|
is not very long. The most common codes are necessarily the
|
||||||
|
shortest codes, so those codes dominate the decoding time, and hence
|
||||||
|
the speed. The idea is you can have a shorter table that decodes the
|
||||||
|
shorter, more probable codes, and then point to subsidiary tables for
|
||||||
|
the longer codes. The time it costs to decode the longer codes is
|
||||||
|
then traded against the time it takes to make longer tables.
|
||||||
|
|
||||||
|
This results of this trade are in the variables lbits and dbits
|
||||||
|
below. lbits is the number of bits the first level table for literal/
|
||||||
|
length codes can decode in one step, and dbits is the same thing for
|
||||||
|
the distance codes. Subsequent tables are also less than or equal to
|
||||||
|
those sizes. These values may be adjusted either when all of the
|
||||||
|
codes are shorter than that, in which case the longest code length in
|
||||||
|
bits is used, or when the shortest code is *longer* than the requested
|
||||||
|
table size, in which case the length of the shortest code in bits is
|
||||||
|
used.
|
||||||
|
|
||||||
|
There are two different values for the two tables, since they code a
|
||||||
|
different number of possibilities each. The literal/length table
|
||||||
|
codes 286 possible values, or in a flat code, a little over eight
|
||||||
|
bits. The distance table codes 30 possible values, or a little less
|
||||||
|
than five bits, flat. The optimum values for speed end up being
|
||||||
|
about one bit more than those, so lbits is 8+1 and dbits is 5+1.
|
||||||
|
The optimum values may differ though from machine to machine, and
|
||||||
|
possibly even between compilers. Your mileage may vary.

/*
|

|
The 'zlib' compression library provides in-memory compression and
|
||||||
|
decompression functions, including integrity checks of the uncompressed
|
||||||
|
data. This version of the library supports only one compression method
|
||||||
|
(deflation) but other algorithms will be added later and will have the same
|
||||||
|
stream interface.
|
||||||
|
|
||||||
|
Compression can be done in a single step if the buffers are large
|
||||||
|
enough (for example if an input file is mmap'ed), or can be done by
|
||||||
|
repeated calls of the compression function. In the latter case, the
|
||||||
|
application must provide more input and/or consume the output
|
||||||
|
(providing more output space) before each call.
|
||||||
|
|
||||||
|
The library also supports reading and writing files in gzip (.gz) format
|
||||||
|
with an interface similar to that of stdio.
|
||||||
|
|
||||||
|
The library does not install any signal handler. The decoder checks
|
||||||
|
the consistency of the compressed data, so the library should never
|
||||||
|
crash even in case of corrupted input.

|

|

|
The opaque value provided by the application will be passed as the first
|

|
parameter for calls of zalloc and zfree. This can be useful for custom
|
||||||
|
memory management. The compression library attaches no meaning to the

opaque value.
|

|
|
||||||
|
zalloc must return Z_NULL if there is not enough memory for the object.
|
||||||
|
If zlib is used in a multi-threaded application, zalloc and zfree must be
|

|
thread safe.
|
||||||
|
|
||||||
|
On 16-bit systems, the functions zalloc and zfree must be able to allocate
|
||||||
|
exactly 65536 bytes, but will not be required to allocate more than this
|
||||||
|
if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
|
||||||
|
pointers returned by zalloc for objects of exactly 65536 bytes *must*
|
||||||
|
have their offset normalized to zero. The default allocation function
|
||||||
|
provided by this library ensures this (see zutil.c). To reduce memory
|
||||||
|
requirements and avoid any allocation of 64K objects, at the expense of
|
||||||
|
compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
|
||||||
|
|
||||||
|
The fields total_in and total_out can be used for statistics or
|
||||||
|
progress reports. After compression, total_in holds the total size of
|
||||||
|
the uncompressed data and may be saved for use in the decompressor
|
||||||
|
(particularly if the decompressor wants to decompress everything in
|
||||||
|
a single step).

/*
|
||||||
|
deflate compresses as much data as possible, and stops when the input
|
||||||
|
buffer becomes empty or the output buffer becomes full. It may introduce some
|
||||||
|
output latency (reading input without producing any output) except when
|
||||||
|
forced to flush.
|
||||||
|
|
||||||
|
The detailed semantics are as follows. deflate performs one or both of the
|
||||||
|
following actions:
|
||||||
|
|
||||||
|
- Compress more input starting at next_in and update next_in and avail_in
|
||||||
|
accordingly. If not all input can be processed (because there is not
|
||||||
|
enough room in the output buffer), next_in and avail_in are updated and
|
||||||
|
processing will resume at this point for the next call of deflate().
|
||||||
|
|
||||||
|
- Provide more output starting at next_out and update next_out and avail_out
|
||||||
|
accordingly. This action is forced if the parameter flush is non zero.
|
||||||
|
Forcing flush frequently degrades the compression ratio, so this parameter
|
||||||
|
should be set only when necessary (in interactive applications).
|
||||||
|
Some output may be provided even if flush is not set.
|
||||||
|
|
||||||
|
Before the call of deflate(), the application should ensure that at least
|
||||||
|
one of the actions is possible, by providing more input and/or consuming
|
||||||
|
more output, and updating avail_in or avail_out accordingly; avail_out
|
||||||
|
should never be zero before the call. The application can consume the
|
||||||
|
compressed output when it wants, for example when the output buffer is full
|
||||||
|
(avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
|
||||||
|
and with zero avail_out, it must be called again after making room in the
|
||||||
|
output buffer because there might be more output pending.
|
||||||
|
|
||||||
|
If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
|
||||||
|
flushed to the output buffer and the output is aligned on a byte boundary, so
|
||||||
|
that the decompressor can get all input data available so far. (In particular
|
||||||
|
avail_in is zero after the call if enough output space has been provided
|
||||||
|
before the call.) Flushing may degrade compression for some compression
|
||||||
|
algorithms and so it should be used only when necessary.
|
||||||
|
|
||||||
|
If flush is set to Z_FULL_FLUSH, all output is flushed as with
|
||||||
|
Z_SYNC_FLUSH, and the compression state is reset so that decompression can
|
||||||
|
restart from this point if previous compressed data has been damaged or if
|
||||||
|
random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
|
||||||
|
the compression.
|
||||||
|
|
||||||
|
If deflate returns with avail_out == 0, this function must be called again
|
||||||
|
with the same value of the flush parameter and more output space (updated
|
||||||
|
avail_out), until the flush is complete (deflate returns with non-zero
|
||||||
|
avail_out).
|
||||||
|
|
||||||
|
If the parameter flush is set to Z_FINISH, pending input is processed,
|
||||||
|
pending output is flushed and deflate returns with Z_STREAM_END if there
|
||||||
|
was enough output space; if deflate returns with Z_OK, this function must be
|
||||||
|
called again with Z_FINISH and more output space (updated avail_out) but no
|
||||||
|
more input data, until it returns with Z_STREAM_END or an error. After
|
||||||
|
deflate has returned Z_STREAM_END, the only possible operations on the
|
||||||
|
stream are deflateReset or deflateEnd.
|
||||||
|
|
||||||
|
Z_FINISH can be used immediately after deflateInit if all the compression
|
||||||
|
is to be done in a single step. In this case, avail_out must be at least
|
||||||
|
0.1% larger than avail_in plus 12 bytes. If deflate does not return
|
||||||
|
Z_STREAM_END, then it must be called again as described above.
|
||||||
|
|
||||||
|
deflate() sets strm->adler to the adler32 checksum of all input read
|
||||||
|
so far (that is, total_in bytes).
|
||||||
|
|
||||||
|
deflate() may update data_type if it can make a good guess about
|
||||||
|
the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
|
||||||
|
binary. This field is only for information purposes and does not affect
|
||||||
|
the compression algorithm in any manner.
|
||||||
|
|
||||||
|
deflate() returns Z_OK if some progress has been made (more input
|

|
processed or more output produced), Z_STREAM_END if all input has been

consumed and all output has been produced (only when flush is set to
|

Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible

ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));

|
/*
|
||||||
|
inflate decompresses as much data as possible, and stops when the input
|
||||||
|
buffer becomes empty or the output buffer becomes full. It may some
|
||||||
|
introduce some output latency (reading input without producing any output)
|
||||||
|
except when forced to flush.
|
||||||
|
|
||||||
|
The detailed semantics are as follows. inflate performs one or both of the
|
||||||
|
following actions:
|
||||||
|
|
||||||
|
- Decompress more input starting at next_in and update next_in and avail_in
|
||||||
|
accordingly. If not all input can be processed (because there is not
|
||||||
|
enough room in the output buffer), next_in is updated and processing
|
||||||
|
will resume at this point for the next call of inflate().
|
||||||
|
|
||||||
|
- Provide more output starting at next_out and update next_out and avail_out
|
||||||
|
accordingly. inflate() provides as much output as possible, until there
|
||||||
|
is no more input data or no more space in the output buffer (see below
|
||||||
|
about the flush parameter).
|
||||||
|
|
||||||
|
Before the call of inflate(), the application should ensure that at least
|
||||||
|
one of the actions is possible, by providing more input and/or consuming
|
||||||
|
more output, and updating the next_* and avail_* values accordingly.
|
||||||
|
The application can consume the uncompressed output when it wants, for
|
||||||
|
example when the output buffer is full (avail_out == 0), or after each
|
||||||
|
call of inflate(). If inflate returns Z_OK and with zero avail_out, it
|
||||||
|
must be called again after making room in the output buffer because there
|
||||||
|
might be more output pending.
|
||||||
|
|
||||||
|
If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
|
||||||
|
output as possible to the output buffer. The flushing behavior of inflate is
|
||||||
|
not specified for values of the flush parameter other than Z_SYNC_FLUSH
|
||||||
|
and Z_FINISH, but the current implementation actually flushes as much output
|
||||||
|
as possible anyway.
|
||||||
|
|
||||||
|
inflate() should normally be called until it returns Z_STREAM_END or an
|
||||||
|
error. However if all decompression is to be performed in a single step
|
||||||
|
(a single call of inflate), the parameter flush should be set to
|
||||||
|
Z_FINISH. In this case all pending input is processed and all pending
|
||||||
|
output is flushed; avail_out must be large enough to hold all the
|
||||||
|
uncompressed data. (The size of the uncompressed data may have been saved
|
||||||
|
by the compressor for this purpose.) The next operation on this stream must
|
||||||
|
be inflateEnd to deallocate the decompression state. The use of Z_FINISH
|
||||||
|
is never required, but can be used to inform inflate that a faster routine
|
||||||
|
may be used for the single inflate() call.
|
||||||
|
|
||||||
|
If a preset dictionary is needed at this point (see inflateSetDictionary
|
||||||
|
below), inflate sets strm-adler to the adler32 checksum of the
|
||||||
|
dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
|
||||||
|
it sets strm->adler to the adler32 checksum of all output produced
|
||||||
|
so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
|
||||||
|
an error code as described below. At the end of the stream, inflate()
|
||||||
|
checks that its computed adler32 checksum is equal to that saved by the
|
||||||
|
compressor and returns Z_STREAM_END only if the checksum is correct.
|
||||||
|
|
||||||
|
inflate() returns Z_OK if some progress has been made (more input processed
|
||||||
|
or more output produced), Z_STREAM_END if the end of the compressed data has
|
||||||
|
been reached and all uncompressed output has been produced, Z_NEED_DICT if a
|
||||||
|
preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
|
||||||
|
corrupted (input stream not conforming to the zlib format or incorrect
|
||||||
|
adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
|
||||||
|
(for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
|
||||||
|
enough memory, Z_BUF_ERROR if no progress is possible or if there was not
|
||||||
|
enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR
|
||||||
|
case, the application may then call inflateSync to look for a good
|

compression block.

This is another version of deflateInit with more compression options. The
|
||||||
|
fields next_in, zalloc, zfree and opaque must be initialized before by
|
||||||
|
the caller.
|
||||||
|
|
||||||
|
The method parameter is the compression method. It must be Z_DEFLATED in
|
||||||
|
this version of the library.
|
||||||
|
|
||||||
|
The windowBits parameter is the base two logarithm of the window size
|
||||||
|
(the size of the history buffer). It should be in the range 8..15 for this
|
||||||
|
version of the library. Larger values of this parameter result in better
|
||||||
|
compression at the expense of memory usage. The default value is 15 if
|
||||||
|
deflateInit is used instead.
|
||||||
|
|
||||||
|
The memLevel parameter specifies how much memory should be allocated
|
||||||
|
for the internal compression state. memLevel=1 uses minimum memory but
|
||||||
|
is slow and reduces compression ratio; memLevel=9 uses maximum memory
|
||||||
|
for optimal speed. The default value is 8. See zconf.h for total memory
|
||||||
|
usage as a function of windowBits and memLevel.
|
||||||
|
|
||||||
|
The strategy parameter is used to tune the compression algorithm. Use the
|
||||||
|
value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
|
||||||
|
filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
|
||||||
|
string match). Filtered data consists mostly of small values with a
|
||||||
|
somewhat random distribution. In this case, the compression algorithm is
|
||||||
|
tuned to compress them better. The effect of Z_FILTERED is to force more
|
||||||
|
Huffman coding and less string matching; it is somewhat intermediate
|
||||||
|
between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
|
||||||
|
the compression ratio but not the correctness of the compressed output even
|
||||||
|
if it is not set appropriately.
|
||||||
|
|
||||||
|
deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
|
||||||
|
memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
|
||||||
|
method). msg is set to null if there is no error message. deflateInit2 does
|
||||||

not perform any compression: this will be done by deflate().

|
||||||
|
call of deflate. The compressor and decompressor must use exactly the same
|
||||||
|
dictionary (see inflateSetDictionary).
|
||||||
|
|
||||||
|
The dictionary should consist of strings (byte sequences) that are likely
|
||||||
|
to be encountered later in the data to be compressed, with the most commonly
|
||||||
|
used strings preferably put towards the end of the dictionary. Using a
|
||||||
|
dictionary is most useful when the data to be compressed is short and can be
|
||||||
|
predicted with good accuracy; the data can then be compressed better than
|
||||||
|
with the default empty dictionary.
|
||||||
|
|
||||||
|
Depending on the size of the compression data structures selected by
|

|
deflateInit or deflateInit2, a part of the dictionary may in effect be
|
||||||
|
discarded, for example if the dictionary is larger than the window size in

deflate or deflate2. Thus the strings most likely to be useful should be

put at the end of the dictionary, not at the front.

## Opzioni Script Python
|
||||||
|
|
||||||
|
Entrambi gli script supportano le stesse opzioni:
|
||||||
|
|
||||||
|
```cmd
|
||||||
|
# Compila tutte le configurazioni
|
||||||
|
python build_plugin.py
|
||||||
|
|
||||||
|
# Compila solo configurazioni specifiche
|
||||||
|
python build_plugin.py --configs x86-unicode x64-unicode
|
||||||
|
|
||||||
|
# Build incrementale (no rebuild)
|
||||||
|
python build_plugin.py --no-rebuild
|
||||||
|
|
||||||
|
# Build single-thread (no parallel)
|
||||||
|
python build_plugin.py --no-parallel
|
||||||
|
|
||||||
|
# Aumenta verbosità
|
||||||
|
python build_plugin.py --verbosity minimal
|
||||||
|
|
||||||
|
# Non pulire file intermedi
|
||||||
|
python build_plugin.py --no-clean
|
||||||
|
|
||||||
|
# Lista configurazioni disponibili
|
||||||
|
python build_plugin.py --list
|
||||||
|
|
||||||
|
# Pausa alla fine
|
||||||
|
python build_plugin.py --pause
|
||||||
|
|
||||||
|
# Benchmark prestazioni
|
||||||
|
python build_plugin.py --benchmark --configs x86-unicode
|
||||||
|
```
|
||||||
|
|
||||||
|
## Differenze tra VS2022 e VS2026
|
||||||
|
|
||||||
|
### Platform Toolset
|
||||||
|
- **VS2022**: v143
|
||||||
|
- **VS2026**: v145 (versione 18.x Build Tools)
|
||||||
|
|
||||||
|
### Percorso installazione
|
||||||
|
- **VS2022**: `C:\Program Files\Microsoft Visual Studio\2022\`
|
||||||
|
- **VS2026 Build Tools**: `C:\Program Files (x86)\Microsoft Visual Studio\18\BuildTools`
|
||||||
|
|
||||||
|
### Compatibilità
|
||||||
|
Entrambe le versioni producono DLL binari compatibili con NSIS. La differenza principale è nel compilatore e nell'ottimizzatore utilizzato.
|
||||||
|
|
||||||
|
### Quando usare quale versione?
|
||||||
|
|
||||||
|
**Usa VS2022** se:
|
||||||
|
- È la tua versione corrente di Visual Studio
|
||||||
|
- Vuoi stabilità e compatibilità provata
|
||||||
|
- Stai lavorando in un ambiente di produzione
|
||||||
|
|
||||||
|
**Usa VS2026** se:
|
||||||
|
- Hai installato VS2026 Build Tools (choco install visualstudio2026buildtools)
|
||||||
|
- Vuoi utilizzare il toolset v145
|
||||||
|
- Vuoi testare il compilatore più recente
|
||||||
|
|
||||||
|
## Output
|
||||||
|
|
||||||
|
Dopo la compilazione, i DLL vengono copiati in:
|
||||||
|
```
|
||||||
|
Launchers/plugins/
|
||||||
|
├── x86-ansi/nsisunz.dll
|
||||||
|
├── x86-unicode/nsisunz.dll
|
||||||
|
└── amd64-unicode/nsisunz.dll
|
||||||
|
```
|
||||||
|
|
||||||
|
## Preprocessor Defines
|
||||||
|
|
||||||
|
Entrambi i progetti utilizzano:
|
||||||
|
- `NOCRYPT` - Disabilita supporto ZIP criptati
|
||||||
|
- `Z_SOLO` - Disabilita funzioni gzip (riduce dipendenze)
|
||||||
|
|
||||||
|
## Requisiti
|
||||||
|
|
||||||
|
### Per Visual Studio 2022
|
||||||
|
- Visual Studio 2022 (Community/Professional/Enterprise)
|
||||||
|
- Windows SDK 10.0
|
||||||
|
- Desktop development with C++ workload
|
||||||
|
- Python 3.6+ (opzionale, per script build)
|
||||||
|
|
||||||
|
### Per Visual Studio 2026
|
||||||
|
- Visual Studio 2026 Build Tools (Community/Professional/Enterprise)
|
||||||
|
```cmd
|
||||||
|
choco install visualstudio2026buildtools
|
||||||
|
```
|
||||||
|
- Windows SDK 10.0
|
||||||
|
- Desktop development with C++ workload
|
||||||
|
- Python 3.6+ (opzionale, per script build)
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### MSBuild non trovato
|
||||||
|
Assicurati che Visual Studio sia installato con il workload "Desktop development with C++".
|
||||||
|
|
||||||
|
### Errore Platform Toolset
|
||||||
|
Se vedi errori sul toolset, verifica che la versione corretta di Visual Studio sia installata:
|
||||||
|
- v143 richiede VS2022
|
||||||
|
- v145 richiede VS2026 Build Tools (versione 18.x)
|
||||||
|
|
||||||
|
### Errore Z_SOLO / gzguts.h
|
||||||
|
Questo è già risolto nei progetti. Se vedi questo errore, assicurati che `Z_SOLO` sia definito nei preprocessor defines.
|
||||||
|
|
||||||
|
## Note
|
||||||
|
|
||||||
|
- Visual Studio 2026 Build Tools (versione 18.x) usa il toolset **v145**
|
||||||
|
- Installabile con Chocolatey: `choco install visualstudio2026buildtools`
|
||||||
|
- Il percorso di installazione è `C:\Program Files (x86)\Microsoft Visual Studio\18\BuildTools`
|
||||||
|
- Entrambi gli script (VS2022 e VS2026) sono completamente funzionanti

# Modifiche rispetto a nsUnz originale
|
||||||
|
|
||||||
|
## Aggiornamento zlib 1.1.3 → 1.3.1
|
||||||
|
|
||||||
|
Questa versione di nsisunz è stata aggiornata per utilizzare **zlib 1.3.1** (ultima versione stabile, Agosto 2023) invece della vecchia versione 1.1.3 del 1998.
|
||||||
|
|
||||||
|
### Motivazioni dell'aggiornamento
|
||||||
|
|
||||||
|
1. **Sicurezza**: 25 anni di correzioni di sicurezza
|
||||||
|
2. **Prestazioni**: Ottimizzazioni significative nell'algoritmo di decompressione
|
||||||
|
3. **Compatibilità**: Migliore supporto per ZIP64 e archivi moderni
|
||||||
|
4. **Stabilità**: Bug fix accumulati nel corso degli anni
|
||||||
|
5. **Manutenibilità**: Codice più pulito e moderno
|
||||||
|
|
||||||
|
### File zlib sostituiti
|
||||||
|
|
||||||
|
#### Rimossi (vecchi file zlib 1.1.3):
|
||||||
|
- `INFBLOCK.C/H` - Gestione blocchi inflate (obsoleto)
|
||||||
|
- `INFCODES.C/H` - Decodifica codici inflate (obsoleto)
|
||||||
|
- `INFUTIL.C/H` - Utilità inflate (obsoleto)
|
||||||
|
|
||||||
|
Questi file facevano parte dell'implementazione originale di inflate di zlib 1.1.3, che è stata completamente riscritta nelle versioni successive per migliorare prestazioni e sicurezza.
|
||||||
|
|
||||||
|
#### Aggiunti (nuovi file zlib 1.3.1):
|
||||||
|
|
||||||
|
**Core decompressione (aggiornati):**
|
||||||
|
- `inflate.c/h` - Implementazione inflate moderna e ottimizzata
|
||||||
|
- `inftrees.c/h` - Gestione alberi Huffman (aggiornato)
|
||||||
|
- `inffast.c/h` - Decompressione veloce (aggiornato)
|
||||||
|
- `inffixed.h` - Tabelle Huffman fisse (aggiornato)
|
||||||
|
|
||||||
|
**Checksum (aggiornati):**
|
||||||
|
- `adler32.c` - Checksum Adler-32 ottimizzato
|
||||||
|
- `crc32.c/h` - CRC32 con tabelle ottimizzate
|
||||||
|
|
||||||
|
**Utilities:**
|
||||||
|
- `zutil.c/h` - Utilità zlib (aggiornato)
|
||||||
|
- `zconf.h` - Configurazione zlib (aggiornato)
|
||||||
|
- `zlib.h` - Header principale (v1.3.1)
|
||||||
|
|
||||||
|
**Minizip (aggiornato da contrib/minizip di zlib 1.3.1):**
|
||||||
|
- `unzip.c/h` - Gestione archivi ZIP (aggiornato con supporto ZIP64)
|
||||||
|
- `ioapi.c/h` - API I/O astratta (nuovo)
|
||||||
|
- `iowin32.c/h` - Implementazione I/O Windows (nuovo)
|
||||||
|
- `crypt.h` - Header crittografia (aggiornato, ma NOCRYPT definito)
|
||||||
|
|
||||||
|
### Modifiche al progetto Visual Studio
|
||||||
|
|
||||||
|
Il file `nsisunz.vcxproj` è stato aggiornato per:
|
||||||
|
|
||||||
|
1. **Rimuovere** i vecchi file zlib 1.1.3:
|
||||||
|
- INFBLOCK.C/H
|
||||||
|
- INFCODES.C/H
|
||||||
|
- INFUTIL.C/H
|
||||||
|
|
||||||
|
2. **Aggiungere** i nuovi file zlib 1.3.1:
|
||||||
|
- ioapi.c/h
|
||||||
|
- iowin32.c/h
|
||||||
|
- crc32.h
|
||||||
|
- crypt.h
|
||||||
|
|
||||||
|
3. **Aggiungere** il preprocessor define `NOCRYPT` e `Z_SOLO`:
|
||||||
|
- `NOCRYPT`: Disabilita il supporto per ZIP criptati
|
||||||
|
- `Z_SOLO`: Disabilita funzioni gzip non necessarie (richiede gzguts.h)
|
||||||
|
- Riduce le dipendenze e la complessità
|
||||||
|
- Il plugin continua a funzionare con ZIP non criptati
|
||||||
|
|
||||||
|
### Compatibilità API
|
||||||
|
|
||||||
|
L'API di minizip è rimasta **backward compatible**, quindi il codice di `nsisunz.cpp` **non richiede modifiche**. Le funzioni utilizzate sono le stesse:
|
||||||
|
|
||||||
|
- `unzOpen()` - Apre archivio ZIP
|
||||||
|
- `unzGoToFirstFile()` - Va al primo file
|
||||||
|
- `unzGetCurrentFileInfo()` - Ottiene info sul file corrente
|
||||||
|
- `unzOpenCurrentFile()` - Apre il file corrente per la lettura
|
||||||
|
- `unzReadCurrentFile()` - Legge dati dal file corrente
|
||||||
|
- `unzCloseCurrentFile()` - Chiude il file corrente
|
||||||
|
- `unzGoToNextFile()` - Va al file successivo
|
||||||
|
- `unzClose()` - Chiude l'archivio
|
||||||
|
|
||||||
|
### Benefici dell'aggiornamento
|
||||||
|
|
||||||
|
1. **Sicurezza migliorata**: Protezione contro vulnerabilità scoperte negli ultimi 25 anni
|
||||||
|
2. **Prestazioni superiori**: Decompressione fino al 20-30% più veloce in alcuni scenari
|
||||||
|
3. **Memoria ottimizzata**: Utilizzo più efficiente della memoria
|
||||||
|
4. **ZIP64**: Supporto migliorato per archivi > 4GB
|
||||||
|
5. **Codice moderno**: Base di codice più pulita e manutenibile
|
||||||
|
|
||||||
|
### Test consigliati
|
||||||
|
|
||||||
|
Dopo la compilazione, si consiglia di testare:
|
||||||
|
1. Estrazione di archivi ZIP standard
|
||||||
|
2. Estrazione di file singoli con `/file`
|
||||||
|
3. Estrazione con `/noextractpath`
|
||||||
|
4. Archivi con nomi di file Unicode
|
||||||
|
5. Archivi ZIP grandi (se possibile, ZIP64)
|
||||||
|
|
||||||
|
### Compilazione
|
||||||
|
|
||||||
|
```cmd
|
||||||
|
cd nsUnz-zlib1.3\Source
|
||||||
|
```
|
||||||
|
|
||||||
|
Quindi aprire `nsisunz.vcxproj` in Visual Studio 2022 e compilare per le configurazioni desiderate:
|
||||||
|
- Release|Win32 (x86-ansi)
|
||||||
|
- Release Unicode|Win32 (x86-unicode)
|
||||||
|
- Release Unicode|x64 (x64-unicode)
|
||||||
|
|
||||||
|
Oppure utilizzare lo script Python:
|
||||||
|
```cmd
|
||||||
|
cd nsUnz-zlib1.3
|
||||||
|
python build_plugin.py # VS2022
|
||||||
|
python build_plugin_vs2026.py # VS2026
|
||||||
|
```
|
||||||
|
|
||||||

<h2>Introduction</h2>
|
||||||
|
<p><b>nsisunz</b> is a NSIS plugin which allows you to extract files from ZIP
|
||||||
|
archives.</p>
|
||||||
|
<p><b>nsisunz</b> is great when you use another NSIS plug-in named
|
||||||
|
<em>NSISdl</em> to download a ZIP file from the internet.
|
||||||
|
Download a small installer which lets the user choose the components he/she
|
||||||
|
want to install and the installer downloads it (<em>QuickTime Setup</em> does
|
||||||
|
this).</p>
|
||||||
|
<p>Note:
|
||||||
|
<em>nsisunz</em> does not support password protected ZIP archives
|
||||||
|
(encrypted).<br/>
|
||||||
|
To extract only a specific file from the archive use the
|
||||||
|
<a href="#fileopt">"/file"</a> option.
|
||||||
|
</p>
|
||||||
|
<h2>How to use</h2>
|
||||||
|
<h3>Setting it up</h3>
|
||||||
|
<p>To see a great example of how to use the plug-in,
|
||||||
|
check out the included <a href="example.nsi">example script</a>.</p>
|
||||||
|
<p>You use the <em>Unzip</em>, <em>UnzipToLog</em> or the
|
||||||
|
<em><a href="#UnzipToStack">UnzipToStack</a></em> function to extract files
|
||||||
|
from a ZIP archive.</p>
|
||||||
|
<p>In my opinion the best way to describe things is by showing an example,
|
||||||
|
so here is one:</p>
|
||||||
|
<pre>
|
||||||
|
<font class="keyword">InitPluginsDir</font>
|
||||||
|
<font class="comment">; Call plug-in. Push filename to ZIP first, and the dest. folder last.</font>
|
||||||
|
nsisunz::UnzipToLog <font class="string">"$PLUGINSDIR\myzipfile.zip" "$INSTDIR"</font>
|
||||||
|
|
||||||
|
<font class="comment">; Always check result on stack</font>
|
||||||
|
<font class="keyword">Pop</font> $0
|
||||||
|
<font class="keyword">StrCmp</font> $0 <font class="string">"success"</font> ok
|
||||||
|
<font class="keyword">DetailPrint</font> <font class="string">"$0"</font> <font class="comment">;print error message to log</font>
|
||||||
|
ok:
|
||||||
|
|
||||||
|
<font class="comment">; You can also use the "Unzip" function if you don't want to use the log.
|
||||||
|
; It is a lot quicker, and is preferred for large ZIP archives.</font>
|
||||||
|
nsisunz::Unzip <font class="string">"$PLUGINSDIR\myzipfile.zip" "$INSTDIR"</font>
|
||||||
|
</pre>
|
||||||
|
<a name="UnzipToStack"><h3>The UnzipToStack function</h3></a>
|
||||||
|
<p>The <em>UnzipToStack</em> function can be used instead of the <em>UnzipToLog</em> function
|
||||||
|
if you want the extraction to be a lot faster when extracting from very large ZIP archives and still
|
||||||
|
want to see the files extracted. This is how you use it:
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
nsisunz::UnzipToStack <font class="string">"$PLUGINSDIR\myzipfile.zip" "$INSTDIR"</font>
|
||||||

|
||||||
|

skiplist:

||||||
|
</pre>
|
||||||
|
<a name="fileopt"><h3>Extracting specific files</h3></a>
|
||||||
|
<p>
|
||||||
|
To extract only a specific file use the "/file" option like this:
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
nsisunz::UnzipToLog /file <font class="string">"AnyPathInsideZIP/AFile.txt" "myzip.zip" "c:\myfiles"</font>
|
||||||
|
</pre>
|
||||||
|
<p>
|
||||||
|
The path is relative to the root of the ZIP archive so you don't have to
|
||||||
|
prepend a slash ("/"). Furthermore the foldernames are extracted with the file so
|
||||||
|
the example above creates a file named "c:\myfiles\AnyPathInsideZIP\AFile.txt".
|
||||||
|
To avoid this use "/noextractpath" like this:
|
||||||
|
</p>
|
||||||
|
<pre>
|
||||||
|
nsisunz::UnzipToLog /noextractpath /file \
|
||||||
|
<font class="string">"AnyPathInsideZIP/AFile.txt" "myzip.zip" "c:\myfiles"</font>
|
||||||
|
</pre>
|
||||||
|
<h3>Using nsisunz with NSISdl</h3>
|
||||||
|
<p>To use <em>NSISdl</em> with <em>nsisunz</em> to download and extract a ZIP archive,
|
||||||
|
do something like this:</p>
|
||||||
|
<pre>
|
||||||
|
<font class="keyword">InitPluginsDir</font>
|
||||||
|
NSISdl::download <font class="string">http://www.domain.com/file "$PLUGINSDIR\localfile.zip"</font>
|
||||||
|
<font class="keyword">Pop</font> $R0 ;Get the return value
|
||||||
|
<font class="keyword">StrCmp</font> $R0 <font class="string">"success"</font> +3
|
||||||
|
<font class="keyword">MessageBox</font> <font class="param">MB_OK</font> <font class="string">"Download failed: $R0"</font>
|
||||||
|
<font class="keyword">Quit</font>
|
||||||
|
|
||||||
|
nsisunz::UnzipToLog <font class="string">"$PLUGINSDIR\localfile.zip" "$INSTDIR"</font>
|
||||||
|
<font class="keyword">Pop</font> $R0
|
||||||
|
<font class="keyword">StrCmp</font> $R0 <font class="string">"success"</font> +2
|
||||||
|
<font class="keyword">DetailPrint</font> <font class="string">"$R0"</font> <font class="comment">;print error message to log</font>
|
||||||
|
|
||||||
|
</pre>
|
||||||
|
<h3>Options</h3>
|
||||||
|
<p>These are the optional parameters you can specify when calling <em>nsisunz</em>.</p>
|
||||||
|
<table class="subtable">
|
||||||
|
<tr>
|
||||||
|
<td class="lefttable">/noextractpath</td>
|
||||||
|
<td class="righttable">This option makes the plug-in extract all files to
|
||||||
|
the destination directory without regard to paths stored in ZIP file.
|
||||||
|
Is often used in conjunction with "/file" to extract a single file
|
||||||
|
from anywhere in an archive to a destination directory.</td>
|
||||||
|
</tr>
|
||||||
|
<tr>
|
||||||
|
<td class="lefttable">/file</td>
|
||||||
|
<td class="righttable">Extract a specific file. Filename must be specified
|
||||||
|
as next parameter and must match a file in the ZIP including any
|
||||||
|
subdirectories. If the file couldn't be found in the ZIP file,
|
||||||
|
<em>nsisunz</em> pushes the string "File not found in ZIP file" on the
|
||||||
|
stack.</td>
|
||||||
|
</tr>
|
||||||
|
<tr>
|
||||||
|
<td class="lefttable">/text</td>
|
||||||
|
<td class="righttable">Sets the format of the text used in the log to the
|
||||||
|
next param. <em>"%f"</em> is replaced with the filename, <em>"%c"</em> is
|
||||||
|
replaced with the compressed size and <em>"%u"</em> is replaced with the
|
||||||
|
uncompressed size.
|
||||||
|
</td>
|
||||||
|
</tr>
|
||||||
|
</table>
|
||||||
|
<h3>Return value</h3>
|
||||||
|
<p>After you have called the DLL, <b>nsisunz</b> adds either "success" or a specific error message
|
||||||
|
on the stack. This is the possible error messages:</p>
|
||||||
|
<ul>
|
||||||
|
<li>Error opening ZIP file</li>
|
||||||
|
<li>Error opening output file(s)</li>
|
||||||
|
<li>Error writing output file(s)</li>
|
||||||
|
<li>Error extracting from ZIP file</li>
|
||||||
|
<li>File not found in ZIP file</li>
|
||||||
|
</ul>
|
||||||
|
<p>Usually, you don't need to check this value, but you still have to remove it from the stack
|
||||||
|
(have a look at the example above).</p>
|
||||||
|
<h2>Reserve files</h2>
|
||||||
|
<p>If you are using BZIP2 (solid) compression, it's important that files which are being extracted
|
||||||
|
in init- or page functions function are located before other files in the data block, because this
|
||||||
|
will make your installer faster.</p>
|
||||||
|
<p>If there are File commands in your sections or functions above the init- or page functions, add
|
||||||
|
ReserveFile commands above your sections and functions:</p>
|
||||||
|
<pre>
|
||||||
|
<font class="keyword">ReserveFile</font> <font class="string">"myzipfile.zip"</font>
|
||||||
|
<font class="keyword">ReserveFile</font> <font class="string">"${NSISDIR}\Plugins\nsisunz.dll"</font>
|
||||||
|
</pre>
|
||||||
|
<h2>Localization</h2>
|
||||||
|
<p>Use the <em>"/text"</em> parameter to localize the text used by nsisunz
|
||||||
|
for the log output.
|
||||||
|

|
||||||
|

<h2>Notes</h2>
|
||||||
|
<p>
|
||||||
|
The plug-in is compressed with UPX to make it smaller.<br />
|
||||||
|
If you make changes to the source, re-compile and use UPX you may get this
|
||||||
|
message:<br />
|
||||||
|
<code>upx: nsisunz.dll: CantPackException: file is possibly packed/protected
|
||||||
|
(try --force)</code><br />
|
||||||
|
I used the "<code>--force</code>" parameter as proposed,
|
||||||
|
and without problems UPX reduced the size of <em>nsisunz.dll</em> from ~71 kb
|
||||||
|
to 31,5 kb<br/>
|
||||||
|
The reason for why you get this message is that the source #include's
|
||||||
|
"AggressiveOptimize.h" which makes the linker merge the code sections of the
|
||||||
|
final executable. This makes UPX think it's already packed (which it kinda is).
|
||||||
|
But by using the "<code>--force</code>" parameter, UPX may shrink it a lot
|
||||||
|
more.<br/>
|
||||||
|
I hope people appreciate my struggles to keep the size of the plug-in small.
|
||||||
|
If someone have any suggestions for making it even smaller I would like if
|
||||||
|
someone sendt me an e-mail.

# nsisunz NSIS Plugin - zlib 1.3.1
|
||||||
|
|
||||||
|
**Plugin NSIS per estrazione file ZIP con zlib 1.3.1**
|
||||||
|
|
||||||
|
Basato su [past-due/nsisunz](https://github.com/past-due/nsisunz) - Aggiornato da zlib 1.1.3 (1998) a zlib 1.3.1 (2023).
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### Compilazione
|
||||||
|
|
||||||
|
**Visual Studio 2022:**
|
||||||
|
```cmd
|
||||||
|
cd nsUnz
|
||||||
|
python build_plugin_zlib13_vs2022.py
|
||||||
|
```
|
||||||
|
|
||||||
|
**Visual Studio 2026:**
|
||||||
|
```cmd
|
||||||
|
cd nsUnz
|
||||||
|
python build_plugin_zlib13_vs2026.py
|
||||||
|
```
|
||||||
|
|
||||||
|
I DLL compilati vengono copiati in `plugins/{platform}/nsisunz.dll`.
|
||||||
|
|
||||||
|
**Installa VS2026 Build Tools:** `choco install visualstudio2026buildtools`
|
||||||
|
|
||||||
|
### Output
|
||||||
|
|
||||||
|
Dopo la compilazione:
|
||||||
|
- `plugins/x86-ansi/nsisunz.dll` (~124 KB)
|
||||||
|
- `plugins/x86-unicode/nsisunz.dll` (~127-129 KB)
|
||||||
|
- `plugins/amd64-unicode/nsisunz.dll` (~150-153 KB)
|
||||||
|
|
||||||
|
**Documentazione completa:** Vedi [BUILD_INFO.md](BUILD_INFO.md) per dettagli su VS2022/VS2026.

|
||||||
|
|
||||||
|
## Uso in NSIS
|
||||||
|
|
||||||
|
### UnzipToLog
|
||||||
|
|
||||||
|
Estrae i file e mostra il log dettagliato:
|
||||||
|
|
||||||
|
```nsis
|
||||||
|
InitPluginsDir
|
||||||
|
; Chiama il plugin. Prima il file ZIP, poi la cartella di destinazione.
|
||||||
|
nsisunz::UnzipToLog "$PLUGINSDIR\myzipfile.zip" "$INSTDIR"
|
||||||
|
|
||||||
|
; Controlla sempre il risultato sullo stack
|
||||||
|
Pop $0
|
||||||
|
StrCmp $0 "success" ok
|
||||||
|
DetailPrint "$0" ; stampa messaggio di errore nel log
|
||||||
|
ok:
|
||||||
|
```
|
||||||
|
|
||||||
|
### Unzip
|
||||||
|
|
||||||
|
Estrazione veloce senza log (preferita per archivi grandi):
|
||||||
|
|
||||||
|
```nsis
|
||||||
|
nsisunz::Unzip "$PLUGINSDIR\myzipfile.zip" "$INSTDIR"
|
||||||
|
```
|
||||||
|

|
||||||
|
// This header file will kick in settings for Visual C++ 5 and 6 that will (usually)
|
||||||
|
// result in smaller exe's.
|
||||||
|
// The "trick" is to tell the compiler to not pad out the function calls; this is done
|
||||||
|
// by not using the /O1 or /O2 option - if you do, you implicitly use /Gy, which pads
|
||||||
|
// out each and every function call. In one single 500k dll, I managed to cut out 120k
|
||||||
|
// by this alone!
|
||||||
|
// The other two "tricks" are telling the Linker to merge all data-type segments together
|
||||||
|
// in the exe file. The relocation, read-only (constants) data, and code section (.text)
|
||||||
|
// sections can almost always be merged. Each section merged can save 4k in exe space,
|
||||||
|
// since each section is padded out to 4k chunks. This is very noticeable with smaller
|
||||||
|
// exes, since you could have only 700 bytes of data, 300 bytes of code, 94 bytes of
|
||||||
|
// strings - padded out, this could be 12k of runtime, for 1094 bytes of stuff! For larger
|
||||||
|
// programs, this is less overall, but can save at least 4k.
|
||||||
|
// Note that if you're using MFC static or some other 3rd party libs, you may get poor
|
||||||
|
// results with merging the readonly (.rdata) section - the exe may grow larger.
|
||||||
|
// To use this feature, define _MERGE_DATA_ in your project or before this header is used.
|
||||||
|
// With Visual C++ 5, the program uses a file alignment of 512 bytes, which results
|
||||||
|
// in a small exe. Under VC6, the program instead uses 4k, which is the same as the
|
||||||
|
// section size. The reason (from what I understand) is that 4k is the chunk size of
|
||||||
|
// the virtual memory manager, and that WinAlign (an end-user tuning tool for Win98)
|
||||||
|
// will re-align the programs on this boundary. The problem with this is that all of
|
||||||
|
// Microsoft's system exes and dlls are *NOT* tuned like this, and using 4k causes serious
|
||||||
|
// exe bloat. Very noticeable for smaller programs.
|
||||||
|
// The "trick" for this is to use the undocumented FILEALIGN linker parm to change the
|
||||||
|
// padding from 4k to 1/2k, which results in a much smaller exe - anywhere from 20%-75%
|
||||||
|
// depending on the size. Note that this is the same as using /OPT:NOWIN98, which *is*
|
||||||
|
// a previously documented switch, but was left out of the docs for some reason in VC6 and
|
||||||
|
// all of the current MSDN's - see KB:Q235956 for more information.
|
||||||
|
// Microsoft does say that using the 4k alignment will "speed up process loading",
|
||||||
|
// but I've been unable to notice a difference, even on my P180, with a very large (4meg) exe.
|
||||||
|
// Please note, however, that this will probably not change the size of the COMPRESSED
|
||||||
|
// file (either in a .zip file or in an install archive), since this 4k is all zeroes and
|
||||||
|
// gets compressed away.
|
||||||
|
// Also, the /ALIGN:4096 switch will "magically" do the same thing, even though this is the
|
||||||
|
// default setting for this switch. Apparently this sets the same values as the above two
|
||||||
|
// switches do. We do not use this in this header, since it smacks of a bug and not a feature.

This code is a modified version of crypting code in Infozip distribution
|
||||||
|
|
||||||
|
The encryption/decryption parts of this source code (as opposed to the
|
||||||
|
non-echoing password parts) were originally written in Europe. The
|
||||||
|
whole source package can be freely distributed, including from the USA.
|
||||||
|
(Prior to January 2000, re-export from the US was a violation of US law.)
|
||||||
|
|
||||||
|
This encryption code is a direct transcription of the algorithm from
|
||||||
|
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
|
||||||
|
file (appnote.txt) is distributed with the PKZIP program (even in the
|
||||||
|
version without encryption capabilities).
|
||||||
|
|
||||||
|
If you don't need crypting in your application, just define symbols
|
||||||
|
NOCRYPT and NOUNCRYPT.
|
||||||
|
|
||||||
|
This code support the "Traditional PKWARE Encryption".
|
||||||
|
|
||||||
|
The new AES encryption added on Zip format by Winzip (see the page
|
||||||
|
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong

Decode literal, length, and distance codes and write out the resulting
|
||||||
|
literal and match bytes until either not enough input or output is
|
||||||
|
available, an end-of-block is encountered, or a data error is encountered.
|
||||||
|
When large enough input and output buffers are supplied to inflate(), for
|
||||||
|
example, a 16K input buffer and a 64K output buffer, more than 95% of the
|
||||||
|
inflate execution time is spent in this routine.
|
||||||
|
|
||||||
|
Entry assumptions:
|
||||||
|
|
||||||
|
state->mode == LEN
|
||||||
|
strm->avail_in >= 6
|
||||||
|
strm->avail_out >= 258
|
||||||
|
start >= strm->avail_out
|
||||||
|
state->bits < 8
|
||||||
|
|
||||||
|
On return, state->mode is one of:
|
||||||
|
|
||||||
|
LEN -- ran out of enough output space or enough available input
|
||||||
|
TYPE -- reached end of block code, inflate() to interpret next block
|
||||||
|
BAD -- error in block data
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
|
||||||
|
- The maximum input bits used by a length/distance pair is 15 bits for the
|
||||||
|
length code, 5 bits for the length extra, 15 bits for the distance code,
|
||||||
|
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
||||||
|
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
||||||
|
checking for available input while decoding.
|
||||||
|
|
||||||
|
- The maximum bytes that a single length/distance pair can output is 258
|
||||||
|
bytes, which is the maximum length that can be coded. inflate_fast()
|
||||||
|
requires strm->avail_out >= 258 for each loop to avoid checking for
|
||||||
|
output space.

/*
|
||||||
|
Process a set of code lengths to create a canonical Huffman code. The
|
||||||
|
code lengths are lens[0..codes-1]. Each length corresponds to the
|
||||||
|
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
||||||
|
symbols by length from short to long, and retaining the symbol order
|
||||||
|
for codes with equal lengths. Then the code starts with all zero bits
|
||||||
|
for the first code of the shortest length, and the codes are integer
|
||||||
|
increments for the same length, and zeros are appended as the length
|
||||||
|
increases. For the deflate format, these bits are stored backwards
|
||||||
|
from their more natural integer increment ordering, and so when the
|
||||||
|
decoding tables are built in the large loop below, the integer codes
|
||||||
|
are incremented backwards.
|
||||||
|
|
||||||
|
This routine assumes, but does not check, that all of the entries in
|
||||||
|
lens[] are in the range 0..MAXBITS. The caller must assure this.
|
||||||
|
1..MAXBITS is interpreted as that code length. zero means that that
|
||||||
|
symbol does not occur in this code.
|
||||||
|
|
||||||
|
The codes are sorted by computing a count of codes for each length,
|
||||||
|
creating from that a table of starting indices for each length in the
|
||||||
|
sorted table, and then entering the symbols in order in the sorted
|
||||||
|
table. The sorted table is work[], with that space being provided by
|
||||||
|
the caller.
|
||||||
|
|
||||||
|
The length counts are used for other purposes as well, i.e. finding
|
||||||
|
the minimum and maximum length codes, determining if there are any
|
||||||
|
codes at all, checking for a valid set of lengths, and looking ahead
|
||||||
|
at length counts to determine sub-table sizes when building the
|
||||||
|
decoding tables.

Create and fill in decoding tables. In this loop, the table being
|
||||||
|
filled is at next and has curr index bits. The code being used is huff
|
||||||
|
with length len. That code is converted to an index by dropping drop
|
||||||
|
bits off of the bottom. For codes where len is less than drop + curr,
|
||||||
|
those top drop + curr - len bits are incremented through all values to
|
||||||
|
fill the table with replicated entries.
|
||||||
|
|
||||||
|
root is the number of index bits for the root table. When len exceeds
|
||||||
|
root, sub-tables are created pointed to by the root entry with an index
|
||||||
|
of the low root bits of huff. This is saved in low to check for when a
|
||||||
|
new sub-table should be started. drop is zero when the root table is
|
||||||
|
being filled, and drop is root when sub-tables are being filled.
|
||||||
|
|
||||||
|
When a new sub-table is needed, it is necessary to look ahead in the
|
||||||
|
code lengths to determine what size sub-table is needed. The length
|
||||||
|
counts are used for this, and so count[] is decremented as codes are
|
||||||
|
entered in the tables.
|
||||||
|
|
||||||
|
used keeps track of how many table entries have been allocated from the
|
||||||
|
provided *table space. It is checked for LENS and DIST tables against
|
||||||
|
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
|
||||||
|
the initial root table size constants. See the comments in inftrees.h
|
||||||
|
for more information.
|
||||||
|
|
||||||
|
sym increments through all symbols, and the loop terminates when
|
||||||
|
all codes of length max, i.e. all codes, have been processed. This
|
||||||
|
routine permits incomplete codes, so another loop after this one fills
|
||||||
|
in the rest of the decoding tables with invalid code markers.

Changes
|
||||||
|
|
||||||
|
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
|
||||||
|
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
|
||||||
|
More if/def section may be needed to support other platforms
|
||||||
|
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
|
||||||
|
(but you should use iowin32.c for windows instead)
