[Gnash-commit] [bug #40459] master-21901-77966b2 doesn’t show downloaded bytes

[Nutchanon Wetchasit]

Follow-up Comment #17, bug #40459 (project gnash):

This issue is still consistenly reproducible on current git version of Gnash
when download simulator is in use.

I have made test SWF files (using libming's MakeSWF), one loader that tries
to download another Flash file from a custom download simulation server
which introduces brief pause on specific positions in the stream:

My loaded SWF in this case is 37288 bytes long. Server output lines begin
with `htcheckpoint:`, loader SWF's output lines begin with `testloader:`.

Following is a trace log from Flash Player (interleaved with server output):

testloader: starting download
htcheckpoint: request received, pausing 2000 ms
htcheckpoint: sent 0 byte(s), pausing 2000 ms
testloader: download started
htcheckpoint: sent 1 byte(s), pausing 2000 ms
Warning: Not a known player download type,

htcheckpoint: sent 37288 byte(s), pausing 2000 ms
testloader: downloading: 37288/37288
testloader: download completed: status 200
testloader: started action


Following is a trace log from Gnash (interleaved with server output):

126 TRACE: testloader: starting download

You'd see that on Gnash...
* `OnLoadStart()` was called when first frame is completed rather than when
HTTP response was received.
* `OnLoadProgress()` was only called only one time when first frame is
completed, rather than every time a block of data is received. Reported number
of bytes downloaded was also inaccurate (20 instead of 1621).
* `OnLoadComplete()` was called even when the download was not yet completed.
HTTP response code reported to the callback was also incorrect (0 instead of
200).

Test SWFs, source code, download simulator script, and full debug logs
are attached as `movieloader-progresscheck.zip`.

Gnash: 0.8.11dev (git 15d61a8 26-Dec-2015)
Flash Player: 11.2 r202 (11.2.202.491) Standalone
System: Debian GNU/Linux 7.0 Wheezy i386

P.S. The download simulation server runs on TCP port 8085 by default;
this it can be changed by adding `-p PORTNUMBER` option to server's
command line. URL in loader SWF must be adjusted accordingly if the port
is changed.
