Is there a way to wrap the file upload/download stream with zlib
compression?
I have to upload and download easily compressible log and csv files.
They're huge, and take a while. I tried shelling out the compression
task, but several coworkers are using windows (I'm on a Mac).
I found Ruby has a built-in zlib library which compresses CSVs and log
files very very nicely.
If no one has already done this, I'm going to try to wrap my file upload
and download tasks with Zlib compression.
I'll then try to extract that functionality and move it into Capistrano
itself.
I'll share the results and propose it as a patch for further release
Here's the uncompressed task I'm using as it stands now.
desc "Upload CSV Files"
task :copy do
Dir.glob("lib/imports/**/*.csv") do |file|
put(File.read(file), "#{shared_path}/#{file}")
end
end
What I'm writing now is
desc "Upload CSV Files"
task :copy do
Dir.glob("lib/imports/**/*.csv") do |file|
put(Deflate.deflate(File.read(file)), "#{shared_path}/#{file}")
# write a rake task that runs zlib inflate on the file
end
end
Here's the syntax I'm shooting for.
desc "Upload CSV Files"
task :copy do
Dir.glob("lib/imports/**/*.csv") do |file|
put(File.read(file), "#{shared_path}/#{file}", :compress=>:zlib)
end
end
I hope this helps!
