I am attempting to expedite python code to extract a supermarkets website's Xpath (store opening and closing hours) to excel file. The code I use works, however it requires adding additional lines of code including new web address and line identifiers.

I have a text file with all the web addresses that need to be visited and the Xpaths are the same so far for each web address. Can python read any file list of web addresses extract the Xpath (store hours) and output to excel file without writing many lines of code?

Since upgrading from Java 8 to Java 11, the Jackrabbit JCR setup in my project has stopped working; it's either not saving or loading the data correctly (haven't quite figured that out yet).

I just wanted to double check that Jackrabbit JCR does support Java 11?

I want to upgrade our Pentaho-server CE installation, from version 7.1 to version 9.0 (because version 7.1 has serious issue with datetime picker and timezones).

However, I cannot turn off our current 7.1 instance, spend few days/weeks to make 9.0 work and than turn that one on. I have to do 9.0 while 7.1 is still running.

To avoid duplicate work, I was thinking about installing 9.0 to alongside currently running 7.1, on the same server, where the database and other stuff is.

I am thinking about 2 options how to make it:

1. Test it during night, at about 22:00 stop 7.1 instance and start 9.0 instance to do all the tests and work, when finished, stop 9.0 and start 7.1 again.
2. Have both instances running simultaneously, on different ports.

I have already checked up about this topic, since I am not very familiar with tomcat. Most of sources only mention ports changing, which is obvious even for me. But I am little bit worried about the internal databases (jackrabbit, quartz and hibernate). Our currently running instance 7.1 is using PostgreSQL for them, and I want to have it that way for 9.0 too. However what I worry about is, that if I run Pentaho9.0 over those internal databases, it will break the older instance 7.1 and make it unusable.

So, my question is, will running pentaho 9.0 over pentaho 7.1 internal databases (jackrabbit, quartz and hibernate) make those incompatible with the 7.1 version? And how to safely run 2 pentaho instances on one machine (while having in mind that the switch from 7.1 to 9.0 in future shouldn't be too complicated :)

I want to migrate binary content from the segmentstore to a new datastore during an repository update. The current version of my repository is 1.6.1. It is using TarMK segmentstore, and has no datastore. In my experience, having binaries in a file datastore offers a considerable boost in performance. So that’s what I want to do with my upgrade to 1.26.0. But how does one copy binaries to a new datastore?

This command migrates my content to the new repository. The application loads the content properly. But there is no datastore.

I need to match a string with the following pattern: "ExactWord (Pattern)"

Pattern consists of one or more words, each separated by a single whitespace or a single hyphen. If a whitespace or hyphen is found immediately after open bracket, it should not match. If a whitespace or hyphen is found immediately before close bracket it should not match.

My current problem is that I cannot write a pattern that won't match multiple spaces and multiple hyphens:

I want to perform some batch operations in JCR (Jackrabit), I need to use org.apache.jackrabbit.spi.Batch (docs), for this I need RepositoryService but I do not know how to obtain the RepositoryService.

Getting below Exception::

I have a Jackrabbit WebDAV server running in Tomcat and I want to know how ETag header value is generated. What class is producing it?

How it can be generated using Java based on initial file and it path in Jackrabbit repository?

The intended flow:

1. Initial file upload to the server
2. If the client is uploading a new file: calculate ETag and compare it with corresponding ETag of file on the server.
3. If values the same - do not upload the file, send response to the client. If values deffer - replace the file on server.

We have run a standard Jackrabbit WebDAV server and uploaded some files in it.

When we upload a new file with the same name we need to check if the file on the server is up to date and shouldn't be replaced. The initial idea was to use ETags but we it turned out to be too weak and is not suitable for the application.

So now the idea is to check the checksum (hash) of the incoming and existing files. As files can be pretty big and downloading everytime can be a time-consuming operation, it's better to have an option to easily obtain checksum for already uploaded files.

So my question: are there any options to get a checksum for files uploaded to the server? Maybe there are some other options or features that will help in such file handling?
