Bug 524864 – app-admin/lastpass - warning [/var/tmp/portage/app-admin/lastpass-3.1.61/distdir/lpchrome_linux.crx]: 306 extra bytes at beginning or within zipfile (attempting to process anyway)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Andrew Udvare 2014-10-09 17:38:17 UTC]

I made sure distfiles no longer had copies of LastPass files.

Everything else here passes fine:

 * lpchrome_linux.crx SHA256 SHA512 WHIRLPOOL size ;-) ... 
 * lp_linux.xpi SHA256 SHA512 WHIRLPOOL size ;-) ...

But then a warning occurs and the ebuild fails. I think the || die on unzip needs to be removed. I never had it in my original ebuild and this might be the reason why.

Obviously, can also filter for errors too.
out=$(unzip -qq ...)
if [[ "$out" = *extra\ bytes* ]]; ...

[Comment 3 Andrew Udvare 2014-10-12 18:41:59 UTC]

Found out the reason why there are 306 bytes at the beginning of the 'zip file', the crx. It is the header for a Chrome extension, which has magic b'Cr24'. Right at byte 307 begins the zip file with the PK magic.

If you want to not have the warning and still use || die, knowing this ahead of time, you can do a little manipulation (I could not find how to pass stdin to unzip):

Do this in src_unpack():
dd bs=306 skip=1 if="${DISTDIR}/lpchrome_linux.crx" of="lpchrome_linux.zip" 2>/dev/null || die
unzip -qq -o "lpchrome_linux.zip" -d "${S}"/crx || die

This works for me and I am attaching a patch. Also, the XPI format for Firefox (which is just a zip) does not add junk the beginning of the zip file.

unzip CRX without warning

Strip the 306 bytes from the beginning of the file which are for Chrome only.

thanks, InCVS.

Do you want to be added as a proxy maintainer (open a new bug if you want to do it).
