1011873 - Google Drive can not be used with new HTTP Cache

Status: RESOLVED DUPLICATE of bug 1010783

(Core :: Networking: Cache, defect)

Description

[Sören Hentzschel]

With the new HTTP cache enabled (default since today) I cannot no longer use my Google Drive documents.

1. make sure that browser.cache.use_new_backend_temp is set to false
2. Go to your Google Drive overview and open a document
3. the document opens as expected
4. set browser.cache.use_new_backend_temp to true
5. repeat step 2
6. you will be redirected to https://support.google.com/accounts/answer/32050
7. restart your browser and test again
8. same problem as described in step 6
9. set browser.cache.use_new_backend_temp to false
10. repeat step 2
11. same problem as described in step 6
12. restart your browser and test again
13. repeat step 2
14. the document opens as expected

You can repeat the steps any number of times, the results is always the same. Google Drive is no longer usable with the new HTTP cache backend because Google redirects you to a help page about caching, a restart of the browser doesn't help. After disabling the new cache backend you have to restart the browser so that Google Drive works.

Simpler STR (100%):
1. Turn on the new cache, otherwise leave the preferences intact
2. Go to https://drive.google.com/?tab=wo&authuser=0#my-drive
3. Refresh (pure F5)
=> Page does NOT show the list, [ Loading... ] at the top is stuck

Broken content is served for few JS files (mainly https://drive.google.com/static/doclist/client/js/1101700167-doclist_modularized_core.js): SyntaxError: missing ; before statement 1101700167-doclist_modularized_core.js:1462

Note: served with Content-Encoding: gzip.

Workaround:
Set browser.cache.disk.preload_chunk_count to 0.

Regression from bug 1010221.  Backing that change out helps, disabling it - by commenting out the continue; statement for loop - does NOT fix this bug.

Cause found, this is a problem with Read() implementation of cache input stream.  Actually deps on 1010783.
