[DXML-1] Stack overflow when parsing huge XML file

Tue, 20 Mar 2012 08:05:15 -0500

This is using Ryan Senior's new 0.0.3-SNAPSHOT.

While trying to parse a huge XML file (7.5 GB compressed, a dump of Wikipedia), got a stack overflow error. Some digging turned up this bug:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6440214

Modifying clojure.data.xml/source-seq to disable the IS_COALESCING property got rid of the error.

The old lazy-xml contrib code worked (although used up tons more memory).

Attached is a patch that adds keyword options to source-seq, parse, and parse-str, allowing the consumer to disable coalescing and sidestep the upstream bug.

[DXML-5] OutOfMemory errors when emitting large XML documents

Tue, 26 Jun 2012 13:37:51 -0500

Emitting large XML documents, fed from lazy-seqs in data.xml does not work. Currently, the lazy-seq is held in a defrecord, which holds onto the head of the lazy-seq and will force it to all be in memory (eventually consuming all available memory). Example code to reproduce the issue below:

Unable to find source-code formatter for language: clojure. Available languages are: javascript, sql, xhtml, actionscript, none, html, xml, java

(with-open [fw (java.io.FileWriter. "/tmp/lots-of-foo.xml")]
    (xml/emit
       (Element. :some-tags
           {}
           (map #(Element. :foo {} [(str "foo" %)])
                (range 0 10000000)))
       fw))

[DXML-3] Build release on JDK 1.6

[DXML-6] data.xml tests fail on clojure 1.2.0 and 1.2.1

Tue, 22 May 2012 12:54:41 -0500

See the test matrix here: http://build.clojure.org/job/data.xml-test-matrix/. Looks like the mixed-quotes test is to blame, just a reordering of attributes when they are emitted to a string.

[DXML-8] Cannot pass strings when keywords are expected

Wed, 14 Nov 2012 07:28:10 -0600

This error does not present till you attempt to emit xml that has a string where the element function is expecting a keyword. This is double hard to figure out at first because the error message is vague. I am requesting that the element function is allowed to use strings instead of keywords or the error message is cleaned up so that the "user" error is clear.

[DXML-11] Support cdata with sexp-as-element

Tue, 8 Jan 2013 22:07:06 -0600

prxml allowed something like this:

(prxml [:foo [:cdata! "all my cdata"]])

It doesn't look like that is currently allowed in data.xml. It looked like maybe I could extend the AsElements protocol to get this behavior, but I couldn't quite figure it out, seems like I'd have to have access to the XmlStreamWriter to get the string representation of the cdata.

[DXML-12] Do the right thing if cdata content contains the cdata end-tag "]]>"

Tue, 8 Jan 2013 22:07:25 -0600

(xml/emit-str (xml/cdata "fooo]]>bar"))

"<?xml version=\"1.0\" encoding=\"UTF-8\"?><![CDATA[fooo]]>bar]]>"

This is invalid xml. The contract for cdata states that it cannot contain the end tag "]]>", so if the cdata function gets passed content that contains it, it should do the right thing, which is probably this:

http://stackoverflow.com/questions/223652/is-there-a-way-to-escape-a-cdata-end-token-in-xml

(split the content so it is emitted as multiple cdata blocks, none of which contain the entire end-tag "]]>").

This is not a purely academic bug report - I actually hit this problem in prxml and fixed it on my fork.

[DXML-7] cannot change encoding when using the indent function

Tue, 9 Oct 2012 22:46:20 -0500

When using the Indent function, and trying to change the encoding, an exception is thrown.

java.lang.IllegalArgumentException: No value supplied for key: [:encoding "UTF-8"]

This seems to be that the options are not being passed from indent to emit correctly.

[DXML-9] Remove some use of reflection in data.xml

Wed, 14 Nov 2012 07:26:09 -0600

There are a couple of occurrences of reflection in the data.xml library
