Betreff: Re: Antwort: Re: [EP-tech] Crawler ends up with 404, dont know how to handle MIME subtype wildcard

To fix your specific problem you need to modify perl_lib/EPrints/Apache/Rewrite.pm on or around line 422:

-                       &&  (index(lc($accept), "text/html") != -1 || index(lc($accept),"*/*") != -1 || $accept eq ""  )   ## header must be text/html, or */*, or undef
+                       &&  (index(lc($accept), "text/html") != -1 || index(lc($accept), "text/*") != -1 || index(lc($accept),"*/*") != -1 || $accept eq ""  )   ## header must be text/html, text/*, */* or undef

I am reviewing the implication of this change and whether any further changes are needed, as I see reference to the accept mime type in several other places and want to see whether setting accept mime type to text/* on other requests would still break things.

Regards

David Newman

Hi Jens,

I can replicate the same problem on 3.4 GitHub HEAD [1].  I have created a GitHub issue for this [2] and will investigate.

Dear all

unfortunately one of our partner crawlers reports a 404 error during the download, The problem occurs when wildcards are used as mime subtype.

Here an example on our repo ZORA - let us try to get publication no. 143147 via CURL:

HTTP 200 status is returned, when
- no Accept header is specified: curl -v https://www.zora.uzh.ch/id/eprint/143147/
- an exact MIME type is specified: curl -v -H 'Accept: text/html' https://www.zora.uzh.ch/id/eprint/143147/
- any MIME type is specified: curl -v -H 'Accept: */*' https://www.zora.uzh.ch/id/eprint/143147/

HTTP 404 status is returned if the MIME subtype is open, e.g. 'text/*'.

==> curl -v -H 'Accept: text/*,application/*' https://www.zora.uzh.ch/id/eprint/143147/

[...]
< HTTP/1.1 404 Not Found
< Date: Mon, 26 Jul 2021 08:23:04 GMT
< Server: Apache/2.4.6 (Red Hat Enterprise Linux) OpenSSL/1.0.2k-fips mod_perl/2.0.11 Perl/v5.16.3
< Cache-Control: no-store, no-cache, must-revalidate
< Strict-Transport-Security: max-age=15780000
< Transfer-Encoding: chunked
< Content-Type: text/html; charset=utf-8

The Header "Accept: text/*,application/*" should be valid. So, we think is goin wrong around CRUD.pm [line 948] - elsif( $subtype eq '*' ) {}

Is this a bug or is there a workaround? Any help is appreciated.

Have a nice day
Jens
