https://crbug.com/362061 was fixed in Chrome 36, and the lowest
supported Chrome version in the extension is Chrome 49, so the
work-around for a filesystem:-bug in chromecom can be removed.
Merge ftp and file handler now their implementations are identical.
Remove redundant comment (the referenced Chrome bug has been fixed
a long time ago - https://crbug.com/302548 ).
This was introduced in #3582 to work around https://crbug.com/274024 .
The bug in Chrome has been fixed a long time ago (at least 33), so let's
simplify the code.
Add comments with supported browser versions where missing.
Method:
- Use MDN compat tables if available.
- Otherwise test in Chrome (31+) otherwise.
(the Chrome Web Store does not update older versions of
Chrome, so probably nobody is interested in even older
versions, even though there is an existing comment for
Chrome<29 at `document.currentScript`).
It turns out that PR 9245 unfortunately broke benchmarking completely, sorry about that!
The bug is that we were attempting to reset the current instance of `StatTimer`, instead of creating a new one as was previously done. By resetting the current instance, the `StatTimer` data fetched in `test/driver.js` is now wiped out since it points to the *same* underlying object.
This re-use of a `StatTimer` instance was asked for during review, and unfortunately I didn't test this thoroughly enough before submitting the final version of the PR.[1]

[1] Note that while I did test the benchmarking scripts with that PR *before* initially submitting it, I did however forget to do that after addressing the review comments which might explain why this problem went unnoticed.
Remove "returns null when content disposition is form-data".
The name of the test is already misleading: It suggests that
the return value is null if the Content-Disposition starts with
"form-data". This is not the case, anything with the "filename"
parameter is accepted.
So, to correct this, one would have to rephrase the test description to
"returns null when content disposition has no filename".
But this is already tested by the test called
"gets the filename from the response header".
So, remove the test.
This patch updates the `IPDFStreamReader` interface and ensures that the interface/implementation of `network.js`, `fetch_stream.js`, `node_stream.js`, and `transport_stream.js` all match properly.
The unit-tests are also adjusted, to more closely replicate the actual behaviour of the various actual `IPDFStreamReader` implementations.
Finally, this patch adjusts the use of the Content-Disposition filename when setting the title in the viewer, and adds `PDFDocumentProperties` support as well.
The `fetch` API is only supported for http(s), even in Chrome extensions.
Because of this limitation, we should use the XMLHttpRequest API when the
requested URL is not a http(s) URL.
Fixes#9361
These were removed in PR 9170, since they were unused in the browsers that we'll support in PDF.js version `2.0`.
However looking at the output of Travis, where a subset of the unit-tests are run using Node.js, there's warnings about `btoa` being undefined. This doesn't appear to cause any errors, which probably explains why we didn't notice this before (despite PR 9201).
When navigating away from the viewer, there's no good reason for disallowing replacement of a *temporary* history entry (in addition to empty ones).
Given that the current position is temporarily added to the browser history using a (short) timeout, the history entry will most likely already be correct when the 'pagehide' event fires. However, if the user is quick enough that might not always be the case, in which case the adjusted logic may help.
Please refer to the PDF specification, in particular http://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.3801570
> A colour space shall be specified in one of two ways:
> - Within a content stream, the CS or cs operator establishes the current colour space parameter in the graphics state. The operand shall always be name object, which either identifies one of the colour spaces that need no additional parameters (DeviceGray, DeviceRGB, DeviceCMYK, or some cases of Pattern) or shall be used as a key in the ColorSpace subdictionary of the current resource dictionary (see 7.8.3, "Resource Dictionaries"). In the latter case, the value of the dictionary entry in turn shall be a colour space array or name. A colour space array shall never be inline within a content stream.
>
> - Outside a content stream, certain objects, such as image XObjects, shall specify a colour space as an explicit parameter, often associated with the key ColorSpace. In this case, the colour space array or name shall always be defined directly as a PDF object, not by an entry in the ColorSpace resource subdictionary. This convention also applies when colour spaces are defined in terms of other colour spaces.
