660962 - Save as web page, complete fails altogether if one element can't be saved

Status: RESOLVED DUPLICATE of bug 313683

(SeaMonkey :: Download & File Handling, defect)

Description

[skierpage]

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0.2pre) Gecko/20110517 Firefox/4.0.2pre SeaMonkey/2.1.1pre

I wanted to save my mindless Facebook yakking, so I chose File > Save As... Web Page, complete.  Apparently some supporting FB file has a security certificate problem, and after viewing the certificate mumbo-jumbo, I get a Download Error alert.  But this results in the entire save failing and all files saved so far disappearing.

Reproducible: Always

Steps to Reproduce:
I'm getting the failure every time but it's almost certainly transient, so reproducing is going to be hard; I think you'll have to create an HTML file that refers to a resource on a server that has an invalid certificate.
1. Go to an https web page whose JS loads resources from a server with an invalid SSL certificate.
2. Choose File > Save As... Web Page, complete

Actual Results:  
Download Manager begins download, then a security alert appears.  The cert error is something roughly like (can't copy and paste the text from the alert, grrrrr):
 www2.sesamestats.com:443 uses an invalid security certificate.
 The certificate is only valid for the following names:
 e248.e.akamai.net , *.akmaihd.net
 (Error code: ssl_error_bad_cert_domain)
 ...
The only option is [Cancel], and after that I get:

 Download Error:
 /path/to/diary/facebook_2011-05_save_files/ai_data/paneltracking could not be saved, because the source file could not be read.
 Try again later, or contact the server administrator.

when I click OK, SeaMonkey deletes the main HTML file and all the supporting files it has already saved.  And this behavior is the bug!

Expected Results:  
SeaMonkey should let me know some supporting file can't be saved, but should not abort the file save of the "meat" of the complete web page.  Or, give me a choice [Abort], [Retry], [Skip this file and continue save]

A workaround is to copy the HTML file and xxx_files directory while the Download Error alert is up and before SeaMonkey deletes them.

I couldn't see a reference to to the web site with cert problems in the HTML that was saved (www2.sesamestats.com), or in a Firebug network trace.
