| Summary | 0001072: Use threaded readers for system command file converters | ||||
| Description | IST: File converters that use system commands (e.g. pdftocairo, qpdf) are implemented with a simple executor that uses non-threaded writer/readers for stdin and stdout/stderr streams. This has the advantage of minimal overhead, but can result in deadlock when the process executing the command halts, because stderr/stdout reaches buffer max, while the converter waits for the process to return, so it can read the streams and unload the buffers. In cases where a repair attempt of an invalid Web Printed PDF's fails and stderr and/or stdout grows really big, a deadlock will occur. SOLL: Apply the advanced command executor for all File converters. This executor prevents deadlock by starting stdout/stderr reading in separate threads, just before waiting for the system command process to finish. | ||||
