Работа с Firefox из tmpfs/Running a persistent Firefox profile from tmpfs

1

Как известно, Firefox любит насиловать винт во время работы, особенно это касается файлов sessionstore.js, webappsstore.sqlite, places.sqlite и cookies.sqlite.

Я долго на это смотрел, скрипел зубами, не выдержал и написал скрипт, который выкидывает профиль в /tmpfs во время запуска, а потом синкает его обратно.

It's well known that Firefox likes thrashing your HDD when it works. This problem seriously affects these files: sessionstore.js, webappsstore.sqlite, places.sqlite and cookies.sqlite.

To solve this problem I've created a bash script which copies a Firefox profile to a temporary RAM based directory and then, when Firefox finishes, this script copies changed files back to a persistent directory.

Mode of action:

1) Edit: ~/.mozilla/firefox and add

[Profile1]
Name=firefox-tmpfs
IsRelative=1
Path=firefox-tmpfs

(if you already have more than one profile, Profile1 should become Profile2,3,4 etc.)

2) Create a directory ~/.mozilla/firefox/firefox-persistent
Within it:

mkdir ad
mkdir bk
mkdir ex
ln -s adblockplus $HOME/.mozilla/firefox/firefox-persistent/ad
ln -s extensions $HOME/.mozilla/firefox/firefox-persistent/ex
ln -s bookmarks $HOME/.mozilla/firefox/firefox-persistent/bk

3) Create a symbolic link from /tmp/firefox-tmpfs to ~/.mozilla/firefox/firefox-tmpfs

Create these two files:

$ cat > fxtmpfs.files
addons.sqlite
blocklist.xml
bookmarks.html
cert8.db
chromeappsstore.sqlite
compatibility.ini
content-prefs.sqlite
cookies.sqlite
downloads.sqlite
extensions.ini
extensions.sqlite
formhistory.sqlite
key3.db
lazarus-backup.sqlite
lazarus.sqlite
localstore.rdf
mimeTypes.rdf
permissions.sqlite
places.sqlite
pluginreg.dat
prefs.js
search.json
secmod.db
sessionstore.js
signons.sqlite

$ cat > fxtmpfs
#! /bin/bash

dvolatile=/tmp/$fxprofile

# $1 - old

	md5old="X"
	if [ -f "$1" ]; then

	fi

		md5new=`md5sum "$2"` || die "md5sum of $2 failed"
	fi

	test -f "$2-journal" && die "WHAT THE FUCK IS GOING ON? YOU ARE STILL RUNNING FIREFOX!"

	if [ "$fsize" -gt 0 ]; then

			/bin/cp -a "$1" "$2" || die "cp from $1 to $2 failed!"
		fi
	fi
}

	copyback "$dvolatile/$i" "$fxpersist/$i"
done

xmessage -center -timeout 5 "All done." &>/dev/null

chmod +x fxtmpfs

Run fxtmpfs.

Молодец, навелосипедил. Мало того, что поиск по ЛОРу выдает N-ное количество подобных скриптов, так еще и вот.

Использовать дисковый кеш для браузера? У вас калькулятор вместо компьютера или модемное соединение?
