Paulo,

Looks like you're facing an issue with the new feature of deleting files missing locally.
I just pushed a commit logging which file we're trying to delete before doing so: 71a7d62

Could you try using glynn from the github repository to get that log and paste it here?

Thanks

@dmathieu I traced what is happening here. NLST command from FTP protocol does not support recursive listing, as Dir.Glob function. I have 1:1 copy on the server and this is happening:

ftp.nlst("#{distant}/**/*") result:

["", "", "/blog/public/css:", "", ".", "..", "animate.min.css", "main.css", "responsive.gs.12col.css", "", "", "/blog/public/images:", "", ".", "..", "eagle.png", "favicon.ico", "flower.png", "logo.png", "", "", "/blog/public/js:", "", ".", "..", "jquery.fitvids.js"]

Dir.glob("#{local}/**/*") result:

["C:/Users/Kamil/_dev/blog/_site/404.html", "C:/Users/Kamil/_dev/blog/_site/ecto-strange-error.html", "C:/Users/Kamil/_dev/blog/_site/feed.xml", "C:/Users/Kamil/_dev/blog/_site/Gemfile", "C:/Users/Kamil/_dev/blog/_site/Gemfile.lock", "C:/Users/Kamil/_dev/blog/_site/hello-world.html", "C:/Users/Kamil/_dev/blog/_site/index.html", "C:/Users/Kamil/_dev/blog/_site/LICENSE.md", "C:/Users/Kamil/_dev/blog/_site/public", "C:/Users/Kamil/_dev/blog/_site/public/css", "C:/Users/Kamil/_dev/blog/_site/public/css/animate.min.css", "C:/Users/Kamil/_dev/blog/_site/public/css/main.css", "C:/Users/Kamil/_dev/blog/_site/public/css/responsive.gs.12col.css", "C:/Users/Kamil/_dev/blog/_site/public/images", "C:/Users/Kamil/_dev/blog/_site/public/images/eagle.png", "C:/Users/Kamil/_dev/blog/_site/public/images/favicon.ico", "C:/Users/Kamil/_dev/blog/_site/public/images/flower.png", "C:/Users/Kamil/_dev/blog/_site/public/images/logo.png", "C:/Users/Kamil/_dev/blog/_site/public/js", "C:/Users/Kamil/_dev/blog/_site/public/js/jquery.fitvids.js", "C:/Users/Kamil/_dev/blog/_site/README.md", "C:/Users/Kamil/_dev/blog/_site/serial-port-details-in-c-sharp.html", "C:/Users/Kamil/_dev/blog/_site/stm-hal-usb-library-hard-fault.html", "C:/Users/Kamil/_dev/blog/_site/stm32-unique-id.html"]

So diff (ftp.nlst("#{distant}/**/*") - Dir.glob("#{local}/**/*")) is:

["", "", "/blog/public/css:", "", ".", "..", "animate.min.css", "main.css", "responsive.gs.12col.css", "", "", "/blog/public/images:", "", ".", "..", "eagle.png", "favicon.ico", "flower.png", "logo.png", "", "", "/blog/public/js:", "", ".", "..", "jquery.fitvids.js"]

In order to this function work properly you must make some changes:

• make recursive FTP listing functionality
• filter list out of dots, empty entries, etc.
• strip local and remote paths to relative matching part
• after that you can make subtraction, and delete unnecessary elements

Also, I think that this missing file removal should be optional, to activate in the .yml file. I personally don't want to delete any data from my server without confirmation.

If you want some additional logs just let me know.

All right, I've yanked the 1.3.0 version.
Any PR fixing this is more than welcome. I will not do it myself though, as I don't have any FTP server handy, and won't ever be able to verify this as working properly.

[dmathieu]

Also, I'm declaring bankruptcy on this repo. I haven't touched an FTP server in over 5 years, and there are much better ways of deploying static websites than with FTP today.

If anyone wants ownership of this repository, I will transfer it to whoever fixes this issue.

[paulocesarpcfj]

Then the error will still occurring or will have a rollback?

Thanks!

[dmathieu]

You must uninstall and reinstall the gem. The error will not occur anymore.
Files missing locally will not be deleted in your FTP server anymore either.

[paulocesarpcfj]

Thanks, it worked!

[dmathieu]

I'm leaving this issue open, as yanking a gem is not a long-term solution :)

[128keaton]

@dmathieu you mention that there are better methods for deploying a static website than over FTP. What other 'recommended' methods are there?

[dmathieu]

GitHub Pages; Heroku static; Amazon S3 are the ones that come out of my mind.

[128keaton]

@dmathieu I get some ridiculously cheap hosting from DirectNic (with excellent uptime and support), but without any command-line access. I guess for me, FTP is still the way to go then

[dmathieu]

Feel free to fix this issue and I'll gladly transfer this repository to you :)

Note: GitHub Pages is free too.
