Serving Intranet from a subpath
by Thomas Klausner 16 Aug '22

16 Aug '22

Hi! (I'm sending this to koha-devel because I guess it's too technical for the general list?) We are running running the "Intranet" inside an actual intranet (i.e. inside a VPN). But this Koha instance is also hosting a related Library whose staff cannot access the VPN. For various reasons it is not possible to mount Koha at it's own domain, so we must make it available at a sub-path (something like "https://www.example.com/foo/koha") For the OPAC, I already implemented a hacky Plack Middleware that does some rather ugly rewriting or URLs and HTML (ughh..). While we could do the same for Intranet, I first wanted to check if it is maybe already possible to mount it under a subpath, i.e. have an Apache use something like ProxyPass /foo/koha/index.html ... ProxyPass /foo/koha/cgi-bin/koha ... Now, while this actually works, the pages returned do not, as all the links they contain point to /cgi-bin/koha (i.e., they loose the mount point and generate bad links). The usual way to solve this is via something like https://metacpan.org/pod/Plack::Middleware::ReverseProxyPath But for this work, two things (one small, one not) have to be changed: * the plack app (i.e. Koha) needs to honor some HTTP Header ENV vars (X_FORWARDED_SCRIPT_NAME, X_TRAVERSAL_PATH) * and all links generated by the app need to also honor those vars. The usual way for the latter is to *not* generate links by concatenating path fragments or hardcoded them in templates (which seems to be what Koha is doing), but to use a function/method to generate all links (to html pages, static assets and endpoints) So for example in a template like prog/en/modules/cataloguing/addbooks.tt we find: <a href="/cgi-bin/koha/mainpage.pl">Home</a> This would need to be changed to <a href=uri_for("/cgi-bin/koha/mainpage.pl")>Home</a> and uri_for needs to take a look at the ENV and fix the link accordingly. (The ugly workaround I am using in an OPAC is to use a Middleware to change the HTML after it's generated by Koha but before it is send to the client. shudder...) So on the one hand this seems to be a small change, but to work it needs to touch ALL templates. (and it will be hard to automatically identify all link-ish text in the templates (href, src, maybe sometimes the url is generated in a template, ...) Another approach would be to set the mount-point into <base href="/foo/koha"> https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base But we would still need to change all the links to relative links, as `base` will ignore absolute links, which is what Koha is using now. though maybe the regex to replace the code is a bit easier (s{/cgi-bin}{cgi-bin}) as it does have to fiddle with quotes etc. Our customer is willing to do the work to implement this (probably also in OPAC), but only if the change will be accepted upstream and be usable by the end of this year (i.e. 22.11). Shall we try to tackle this? Or will this massive change never be accepted? If there is interest, I guess the next step is to open a bug...

Using Template::Toolkit WRAPPER templates with Koha Plugins
by dcook＠prosentient.com.au 11 Aug '22

11 Aug '22

Hi all, I'm creating a Koha plugin and I'm going to need several different template pages. Rather than copying and pasting boilerplate into each file, I just created 1 wrapper file and then I include that in each of my individual template pages. For the templates and code, you can take a look at https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31339 I think it would be useful to have some wrapper templates in the Koha core code for plugins, but even if folk have to bundle their own wrappers in their own plugins, I think it's a good practice.

Managing SIP2 connections
by dcook＠prosentient.com.au 09 Aug '22

09 Aug '22

Hi all, Out of the box, the SIP2 server just handles 1 connection at a time. While this might be OK for some libraries, it would be good to update our configuration to make this more explicit. I've got a 1 line change to etc/SIPconfig.xml that does this just so that it's clearer what Koha's SIP server is doing out of the box. It would be great to get a sign off and QA on this one. Should be very fast and easy to do. https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31033 David Cook Senior Software Engineer Prosentient Systems Suite 7.03 6a Glen St Milsons Point NSW 2061 Australia Office: 02 9212 0899 Online: 02 8005 0595

Getting "count" when using REST API
by dcook＠prosentient.com.au 04 Aug '22

04 Aug '22

Hi all, Is there a method for getting a "count" using the REST API without fetching every record? When building a paging lookup outside of Koha, it would be useful to get a total record count and then just fetch the page of records that you need. Thanks!

Does anyone use Basket Groups in Acquisitions?

Hi all, Does anyone use Basket Groups in Acquisitions? I've never understood the utility, so I've thought about just hiding the option all together. Curious if Koha even needs it?
