Add features on router

Add :

• Gin Tonic Group route features
• default route group for no group
• func to allow init later a status router
• func to allow register in group a status router
• func to allow register in group a static router
• interface for Register in Group in router package
• check in header to avoid null map/slice

Change :

• issue #14 : add func SetGinHandler and mark SetGinHnadler as deprecated
• Issue #16 : fix init headers model
• bump dependancies

Add Package for archive/compressed files

Add Package Archive :

• func ExtractFile : recursive func to extract from any (zip, tar, bz2, gzip) archive/compressed file
• allow to push multiple compressed file, search for included file
• search based on included full path name and substrings pattern or regex matching
• return an os file pointer to temporary file

Add I/O Functions for temporary file :

• func NewTempFile to return an os Temp File pointer
• func GeTempFilePath to return the current full path of the given os Temp File pointer
• func DelTempFile to clean the given os Temp File pointer

Add test / example file for Archive Package :

• add a to test to print content of a go file in vendor folder from a zip => bz2 => tar => gzip => tar => vendor/.../file to print
• add a shell script to create an the example archive zip

Pkg Progress

Fix :

• decor bar counter

Update Package Progress

Add

• increment func in bar interface
• refill func in bar interface
• getMpb to get MPB lib objet in both bar & progresss interface
• add func NewBarSimpleCounter to use counter instead of ETA in progress interface

Chg

• rename func NewBarSimple to NewBarSimpleETA in progress interface

Add Package ProgressBar

Add Package Progress Bar :

• use multi bar lib (github.com/vbauerster/mpb/v5)
• implement njs-semaphore link
• update dependancies

Fix :

• build C (njs-ioutils) :
  use /usr/bin/[i686|x86_64]github.com/vbauerster/mpb/v5 -c maxstdio.c instead of gcc -c maxstdio.c to prevent implicit declaration

Add implementation of FD NOFILE rlimit

The rLimit is not implemented in Go for Windows.
This is beacause strictly rLimit does not exist in Windows.
But security of Windows use similar function to limite File Descriptor I/O
This version add a implementation of C call of the windows function to offer similar functionnalities

For Windows build, please follow this note :

Install required packages

Install package to build C source with GCC (need sometimes to details package x86_64 for win64 and i686 for win32 package)

• gcc-multilib
• gcc-mingw-w64

sudo apt-get install gcc-multilib gcc-mingw-w64 

Normally, you will having this binaries

• i686-w64-mingw32* for 32-bit Windows;
• x86_64-w64-mingw32* for 64-bit Windows.

Locate you binaries gcc mingw path and note it:

• win32 : updatedb && locate i686-w64-mingw32-gcc
• win64 : updatedb && locate x86_64-w64-mingw32-gcc

Rebuild object C if needed

if you have an error in the build, or if the .o object file is not present in golib/njg-ioutils/maxstdio/, run this step

cd golib/njg-ioutils/maxstdio 
gcc -c maxstdio.c

Build you go code with the C dependancies :

We will specify some env var in prefix of launching line of go build.
We recommend to use the -a flag of go build to force system to rebuild all dependancies and do not use precompiled code

For Win32 :

CC=/usr/bin/i686-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=386 go build -a -v ...

For Win64 :

CC=/usr/bin/x86_64-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -a -v ...

Add new package semaphore & new function in IOutils

Add new package for semaphore :

• Semaphore interface
• constructor with context handling
• func for managing worker
• func for cancel

Add func for IOutils

• fileDescriptor function to retrieve or try to change the current file descriptor setting

Change :

• Bump dependancies

Fix console/color

Fix :

• issue 03 : missing calling lib functionn

Add :

• Add function buffPrintf : printf directly into a bufio pointer

Chg :

• Bump dependancies

Add trace option in package Errors

Add trace management in error package :

• Upd function ErrorWithCode to ErrorFull in ErrorCode interface
• Upd function StringWithCode to StringFull in ErrorCode interface
• Add attached function Trace in ErrorCode interface
• Upd function GetErrorCode
• Add function GetTraceErrorCode
• Fix doc comments

Add Package njs-errors
