Exist: [BUG] Crypto module broken in eXist develop

[joewiz]

Describe the bug

Any query that imports the crypto module returns the following error:

Cannot compile xquery: exerr:ERROR error found while loading module crypto: Unable to instantiate module from EXPathrepository: org.expath.exist.crypto.ExistExpathCryptoModule

This bug does not affect eXist 5.2.0.

Expected behavior

Imports of the crypto module should not raise this error.

To Reproduce

The following query triggers the error:

xquery version "3.1";

import module namespace crypto = "http://expath.org/ns/crypto";

Context (please always complete the following information):

• OS: macOS 10.15.6
• eXist-db version: eXist 5.3.0-SNAPSHOT 3c26d39ad84dd15420064b23bb1f091716331837 20200923074340
• Java Version: liberica-jdk11-full (openjdk version "11.0.8" 2020-07-14 LTS)

Additional context

• How is eXist-db installed? build from source
• Any custom changes in e.g. conf.xml? none

[adamretter]

Hmm eXist-db 5.2.0 and 5.3.0-SNAPSHOT should be API compatible... at least in terms of a public API.

I wonder if the problem is either:

1. The Crypto Module uses an internal API that has changed? If so, the Crypto module will need to be updated for 5.3.0-SNAPSHOT
2. We have accidentally changed a public API between 5.2.0 and 5.3.0-SNAPSHOT? If so, we should reinstate compatibility in eXist-db 5.3.0-SNAPSHOT.

it is a dependency issue: from the expath logfile:

it has been removed 14 days ago, as the actual code is now upstream in apache commons-io. Great achievement by Adam! link

@claudius108 please could you rework your plugin to match the commons-io equivalent?

[claudius108]

@dizzzz Sure.

when I update/ install the crypto lib to version 5.3.0 the following error is raised when imported

Error: It is a static error if multiple functions declared or imported by a module have the number of arguments and their expanded QNames are equal (as defined by the eq operator). Error while loading module xmldb:///db/system/repo/jwt-1.0.1/test/jwt-spec.xqm: error found while loading module jwt: Error while loading module : Prolog has more than one imported module that defines the function: {http://expath.org/ns/crypto}generate-signature#7

[line-o]

Also it is hard to explain to people outside the community why the version changed to 5.3.0

Hi,

I have no idea about the module
xmldb:///db/system/repo/jwt-1.0.1/test/jwt-spec.xqm.

The version 5.3.0 is to synchronize the module with eXist versions.

It happens with any library importing the crypto lib on 5.3.0-SNAPSHOT see the end of the error ... Prolog has more than one imported module that defines the function: {http://expath.org/ns/crypto}generate-signature#7

I am strongly in favour of semantic versioning. Since the new version of the crypto-lib introduces a breaking change to the current one, the new version should be 2.0.0

I do not see the need to synchronise its version with existdb. None of the bundled applications and libraries have that.

Could it be that the crypto module defines more than one generate-signature function of the same arity? If so that would be an error!
