Hi all...

Can anyone recommend an archive utility that can get into "omni.ja" listed inside the seamonkey folder (usr/lib?)

The native archive utility in Ubuntu (which is what I use on my laptop,) is able to open this file but Puppy's can't.

Thanks...

What is omni.ja used to ? It's big stuff !
"Note: Starting with Firefox 10 and Thunderbird 10, the file extension .ja is used because Windows System Restore does not back up files with the .jar extension, but it does back up .ja files. This change was needed to prevent Firefox from becoming corrupted."

Hamoudoudou, have you tried it? Can you decipher any difference in speed?

Guessing, but I think you could just reverse the process: use something like peazip to pack it as a zip file, and then rename the file, changing its suffix from zip to ja.

In woofQ, the builder for EasyOS, the script buildeasydistro expands omni.ja, and puts it together again.

As omni.ja is inside q.sfs, a Squashfs file that is already compressed (gzip or xz), it slows down SeaMonkey/Firefox for omni.ja to also be compressed.

Hence, I expand it, then recreate the zip without any compression. Here is the code:

Code:
[ -e rootfs-complete/usr/lib/seamonkey ] && MOZDIR='seamonkey' #170429
[ -e rootfs-complete/usr/lib/firefox ] && MOZDIR='firefox' #170429
 if [ -f rootfs-complete/usr/lib/${MOZDIR}/omni.ja ];then
  echo "Uncompressing rootfs-complete/usr/lib/${MOZDIR}/omni.ja..."
  mv -f rootfs-complete/usr/lib/${MOZDIR}/omni.ja ./omni.zip
  mkdir expand1
  unzip -X -K -o -b omni.zip -d expand1 > /dev/null
  cd expand1
  zip -0 -y -r ../omni.ja * > /dev/null
  cd ..
  mv -f omni.ja rootfs-complete/usr/lib/${MOZDIR}/
  sync
  rm -rf expand1
  echo " ...done"
 fi

Thank you very much for information.
1st short tests were successful.

what for a file type is the original omni.ja ?
Doesn't look like a regular zip file.

Header starts with: # 00 00 00 00 50 4B 01 02 ...
never heard before of this.
unzip is complaining too.

Code:
# unzip -X -K -o -b omni.zip -d expand1 > /dev/null
  warning [omni.zip]:  18280129 extra bytes at beginning or within zipfile
  (attempting to process anyway)
  error [omni.zip]:  reported length of central directory is
  -18280129 bytes too long (Atari STZip zipfile?  J.H.Holm ZIPSPLIT 1.1
  zipfile?).  Compensating...


Hope not to lose information after repacking.
Most probably it's better to make the changes before compiling.
Once again thank you.

I have been doing this for a couple of years, for SeaMonkey, and omni.ja works after repacking. No discernable loss of data.

my purpose was to study wat are used for big stuff as omni.ja. I thought that was for Japanese users Smile It is not and if you remove it, you will get problems. That was the only conclusion i Got for omni.ja Smile
In fact omni is a java file.
