I'm using java 1.8.0_211 on ubuntu18.04
in my build.gradle the deps for jackson are
jooqdbCompile "com.fasterxml.jackson.core:jackson-databind:2.9.+"
jooqdbCompile "com.fasterxml.jackson.core:jackson-core:2.9.+"
jooqdbCompile "com.fasterxml.jackson.core:jackson-annotations:2.9.+"
(I did just notice today that a 2.10 exists)
>From this
public static void writeAsString(AbstractPayload payload, String outdirName) {
File ofile = new File(outdirName, payload.getRunTag().toString()+
".json.gz");
try (FileOutputStream fos = new FileOutputStream(ofile);
GZIPOutputStream zos = new GZIPOutputStream(fos,true) ) {
logger.error("Writing to file: {}", ofile.getCanonicalPath());
payload.asJson(zos);
}
catch (Exception e) {
logger.error ("Complete write failure of payload {}",
payload.getRunTag(), e);
e.printStackTrace();
}
}
to the "asJson" call here
public void asJson(OutputStream stream) {
try {
getObjectMapper().writeValue(stream, this);
}
catch (Exception e) {
e.printStackTrace();
logger.error("{}: could not serialize to stream", getRunTag());
}
}
and the "getObjectMapper() call is
private ObjectMapper getObjectMapper() {
if (objectMapper == null) {
objectMapper = new ObjectMapper();
objectMapper.configure(SerializationFeature.INDENT_OUTPUT, false);
objectMapper.configure(JsonGenerator.Feature.AUTO_CLOSE_TARGET, false);
objectMapper.setDefaultPropertyInclusion(JsonInclude.Value.construct(Include.NON_EMPTY,
Include.ALWAYS));
}
return objectMapper;
}
I see plenty of flush()ing jackson-core so I don't think that's the problem,
but putting the GZIPOutputStream in a try/with appeared to help. Prior to that,
small "payloads" (typically under 2K bytes) where getting written as 10-byte
files.
gzip -d just complains and does nothing to the source json.gz file
I can zcat the json.gz files successfully, but do get the gzip error messages:
zcat test/crashpad/chaser/db182faa-cafd-47e9-9798-bc645486ffe1.json.gz | python
-m json.tool >/tmp/c.json
gzip: test/crashpad/chaser/db182faa-cafd-47e9-9798-bc645486ffe1.json.gz:
unexpected end of file
tail -f /tmp/c.json

}
}
}
