I do not think, that we really need a java script engine. We should try to simply skip this page.
I cannot fix it at the moment, because I'm in holiday.

  It will be hard to verify this being fixed since the error was intermittent. Let's assume it is fixed, though. Thank you for the commit!

HI,

i still have this issue? I recompiled esniper from the master which does not solved it. Also version 2.35.1 is still shown in the logs, is this correct?

Cheers,
Nils

It seems, that simply skipping the "Validating JavaScript Engine"-Page will not help, because the required infos are not passed to the caller:

getJson cannot find "tmxSessionId" (globalDfpContext)

Currently it's difficult to analyse, because this error doesn't occur permanently.

I never had such error at all.

@Nils:
Could yo please try the attached auction.c ? I've modified the "Validating JavaScript Engine"-Handling, but I cannot try it out, because I get no "Validating JavaScript Engine"-Error.

  @msporleder: It seems that the problem is solved. Yesterday a could easily reproduce it and now I can place a bid again. Have some auction ending today and will watch it.

Do you see a message "ebayLogin(): Try to login without java script (attempt=%d)" in your log file ? If not, the new mechanism wasn't used by esniper.

  No, did not see it. The error is also back again with same error message.

    Please attach the log file. With the auction.c above the "Java Engine" issue is handled during the login procedure. Maybe it occurs also in other situations.

After I used the debug option "-d" it also occurs every time I start esniper.
Please try the new attached auction.c. With this new file the error messages are suppressed, if a "Java Engine" page was received.
I'm not sure, if the sniping works. I've currently have some actions ending tomorrow.

  It works for me actually but will watch it. ... was like this sometimes before but got no error message yet.

I've commited my changes to auction.c to git - see [4a59da].

From now on you get a warning message like

Warning: Pagename "Validating JavaScript Engine" found (Response to login).

but no Bug Report will be generated. I hope, it helps ...

Hi Michael,

the special test auction.c seems to work fine. I updated now to the main repo and esniper cannot login anymore. But after 3 tries it logged successfully now.

I did not know if this is related to our correction but I like to send you the logs. Perhaps this helps to identify it. As it is running now I will watch it and will let you know if there is an issue.

Cheers,
Nils

Also direct bidding does not work with the attached error. Seems to be another error perhaps...

We skip over the login procedure, which is blocked by the annoying "Java Engine"-Page and the log in never really occurred. When esniper want to place a bid a captcha page blocks the bidding process.

What we need is a strategy to login without being interrupted by a java test. At the moment I've no idea, how to solve this issue.

With commit [b5903d] the login-page was changed. Currently there exists at least two different versions:

https://signin.ebay.com/ws/eBayISAPI.dll (legacy form)
https://www.ebay.com/signin/s (current form)

The new one seems to check for a "Java Engine" from time to time.
Maybe we should try to use the "legacy form" (previously located at www.ebay.com/signin/s).

If I disable java script in my browser, I get this picture:

https://www.magentacloud.de/lnk/9zIDIp4T

This differs from the page "Validating JavaScript Engine". Maybe not all ebay-Server deliver the same content or it depents on other parameters, why the "Validating JavaScript Engine" page appears in some cases.

Did you still changed it. Compiled the actual version and could place a bid again.

JavaScript is checked at other places also like the search result page. So perhaps there is a way to simulate JavaScript execution anyhow.
