NetUtil.jsm Just Got More Useful
Recently, a few bugs have landed enabling a bunch of nice things for consumers of NetUtil.jsm:
- NetUtil.newURI can take a string (plus optional character set and base URI) or an nsIFile.
- A new method for creating channels has been created. NetUtil.newChannel can take an nsIURI, a string (plus optional character set and base URI), or an nsIFile.
- NetUtil.asyncFetch can take an nsIChannel, an nsIURI, a string (plus optional character set and base URI), or an nsIFile.
This means, among other things, that it now requires less code to read a file asynchronously than it does synchronously. The old way to do this asynchronously can be seen here on MDC. This would give the consumer a byte array of the data in the file. Compared to the synchronous case, which can be seen here. Both are pretty verbose and clunky to use. The new way looks like this:
NetUtil.asyncFetch(file, function(aInputStream, aResult) {
if (!Components.isSuccessCode(aResult)) {
// Handle Error
return;
}
// Consume input stream
});
One function call, with a callback passed in. There is a slight difference from the old asynchronous method, however. NetUtil.asyncFetch gives the consumer an nsIInputStream instead of a byte array. The input stream is a bit more useful than a raw byte array, although it can be painful to use in JavaScript at times (maybe we need an easy method to convert an input stream to a string?). I look forward to patches using this method to read files instead of doing it synchronously.

Installing Raindrop on Dreamhost
It turns out that installing Raindrop is really hard. Here’s what I didtried to get it running on Dreamhost. Hope it helps anyone else who wants to play around with it, and I hope they can get further than I did.
Directory structure
In my home directory, I created a new folder called opt.
mkdir opt
You’ll also want to add the following lines to your .bashrc file:
export CFLAGS="-I$HOME/opt/include -L$HOME/opt/lib $CFLAGS"
export CXXFLAGS="-I$HOME/opt/include -L$HOME/opt/lib $CXXFLAGS"
I also created a sources directory, where I’ll be putting all of my source files in.
mkdir sources
We’ll want to be in the sources directory as we install everything.
cd sources
Installation Fun
Install python
wget http://www.python.org/ftp/python/2.6.4/Python-2.6.4.tgz
tar xvfz Python-2.6.4.tgz
cd Python-2.6.4
./configure --prefix=/home/sdwilsh/opt/
make
make install
Install OpenSSL
After you get the source from a mirror and untar it, enter that directory, and run these commands:
./config --prefix=/home/sdwilsh/opt --openssldir=/home/sdwilsh/opt/openssl shared
make
make install
Install Erlang
Note: I had to bump my memory on my PS up to 304 MB (from 150 MB) in order for this to compile. I just doubled it, so you may be able to get by with less. This also takes a while to install.
wget http://erlang.org/download/otp_src_R13B02-1.tar.gz
tar xvfz otp_src_R13B02-1.tar.gz
cd otp_src_R13B02-1
./configure --prefix=/home/sdwilsh/opt/ --with-ssl=/home/sdwilsh/opt/
make
make install
Install ICU
wget http://download.icu-project.org/files/icu4c/4.2.1/icu4c-4_2_1-src.tgz
tar xvfz icu4c-4_2_1-src.tgz
cd icu/
chmod +x runConfigureICU configure install-sh
./runConfigureICU Linux --prefix=/home/sdwilsh/opt
make
make check
make install
Install autoconf-2.13
wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.13.tar.gz
tar xvfz autoconf-2.13.tar.gz
./configure --prefix=/home/sdwilsh/opt/
make
make install
Install Spidermonkey
Note: You many need to install Mercurial. I used easy_install to do.
hg clone http://hg.mozilla.org/releases/mozilla-1.9.2/
cd mozilla-1.9.2/
hg update -r FIREFOX_3_6b3_RELEASE
cd js/src/
autoconf
mkdir build-release
cd build-release
../configure --prefix=/home/sdwilsh/opt/
make
make install
Install libssh2
wget http://www.libssh2.org/download/libssh2-1.2.2.tar.gz
tar xvfz libssh2-1.2.2.tar.gz
cd libssh2-1.2.2
./configure --prefix=/home/sdwilsh/opt/ --with-openssl
make
make install
Install curl
After you get the source from a mirror and untar it, enter that directory, and run these commands:
cd curl-7.19.7
./configure --prefix=/home/sdwilsh/opt/ --with-libssh2=/home/sdwilsh/opt --with-ssl=/home/sdwilsh/opt
make
make install
Install couchdb
After you get the source from a mirror and untar it, enter that directory, and run these commands:
./configure --prefix=/home/sdwilsh/opt/ --with-erlang=/home/sdwilsh/sources/otp_src_R13B02-1/include --with-js-include=/home/sdwilsh/opt/include --with-js-lib=/home/sdwilsh/opt/lib --with-erlang=/home/sdwilsh/opt/lib/erlang/usr/include
make
make install
Note: I feel like I may have messed up how I installed erlang given the strange place it put its header files, but I wasn’t about to recompile it.
Change Permissions & Run
CouchDB suggests you create a new user for to run it is, but this is hard to do it seems, so I skipped it. I did change the permissions, however.
chmod -R 0770 /home/sdwilsh/opt/etc/couchdb
chmod -R 0770 /home/sdwilsh/opt/var/lib/couchdb
chmod -R 0770 /home/sdwilsh/opt/var/log/couchdb
chmod -R 0770 /home/sdwilsh/opt/var/run/couchdb
And now to run CouchDB:
couchdb -b
Sadly, this was taking something close to 500MB of memory. This is far to high for my server to sustain, so I haven’t gotten any further. If anyone has any ideas, I’d be glad to hear them.
