Subject [jira] [Commented] (FOP-2146) Wrong FontCache-Directory used for not existing userHome in FontCache.getDefaultCacheFile() (Bug 47786 was not fixed correctly)
Date Wed, 27 May 2020 09:35:00 GMT

    [ https://issues.apache.org/jira/browse/FOP-2146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17117576#comment-17117576
] 

Simon Steiner commented on FOP-2146:
------------------------------------

I think you use EnvironmentalProfileFactory.createRestrictedIO to disable font caching
{code:java}
        String fopxconf = "<fop version=\"1.0\"></fop>";
        ResourceResolver cloudResourceResolver = ResourceResolverFactory.createDefaultResourceResolver();
        FopFactoryBuilder confBuilder = new FopConfParser(new ByteArrayInputStream(fopxconf.getBytes()),
                EnvironmentalProfileFactory.createRestrictedIO(new File(".").toURI(), cloudResourceResolver)).getFopFactoryBuilder();
        FopFactory fopFactory = confBuilder.build();
        FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
        FileOutputStream fos = new FileOutputStream("out.png");
        Fop fop = fopFactory.newFop("image/png", foUserAgent, fos);
        TransformerFactory factory = TransformerFactory.newInstance();
        Transformer transformer = factory.newTransformer();
        Source src = new StreamSource(new ByteArrayInputStream(fo.getBytes()));
        Result res = new SAXResult(fop.getDefaultHandler());
        transformer.transform(src, res);
        fos.close();

> Method getDefaultCacheFile() returns an invalid file name if the user has no home directory
set. In that case the name of the fop user directory (FOP_USER_DIR!) is returned and not the
name of the cache file (DEFAULT_CACHE_FILENAME).
> Wrong Code:
>     public static File getDefaultCacheFile(boolean forWriting) {
>         File userHome = getUserHome();
>         if (userHome != null) {
>             File fopUserDir = new File(userHome, FOP_USER_DIR);
>             if (forWriting) {
>                 boolean writable = fopUserDir.canWrite();
>                 if (!fopUserDir.exists()) {
>                     writable = fopUserDir.mkdir();
>                 }
>                 if (!writable) {
>                     userHome = getTempDirectory();
>                     fopUserDir = new File(userHome, FOP_USER_DIR);
>                     fopUserDir.mkdir();
>                 }
>             }
>             return new File(fopUserDir, DEFAULT_CACHE_FILENAME);
>         }
>         return new File(FOP_USER_DIR);
>     }
> If getUserHome() does not return a directory the default name must be returned (and not
the name of the directory):
>         return new File(DEFAULT_CACHE_FILENAME);
