Jens Geyer updated THRIFT-1815: ------------------------------- Attachment: THRIFT-1815-endl-patch-for-go-v2.patch > Code generators line buffer output > ---------------------------------- > > Key: THRIFT-1815 > URL: https://issues.apache.org/jira/browse/THRIFT-1815 > Project: Thrift > Issue Type: Improvement > Components: Compiler (General) > Affects Versions: 0.9 > Reporter: Andrew Gaul > Labels: performance > Fix For: 0.9.1, 0.9.2 > > Attachments: THRIFT-1815-endl-patch-for-go-v2.patch, > thrift-1815-compiler-line-buffering.patch > > > This results in slow performance on FUSE- and network-based filesystems, > e.g., eCryptfs. std::ostream << std::endl emits a newline and flushes > buffers to the kernel[1], yielding excessive system calls. Instead, emit > "\n" which does the equivalent without the flush[2]. The attached patch > accomplishes this while minimizing code churn by removing "using namespace > std" and introducing a static variable endl. > [1] http://www.cplusplus.com/reference/ios/endl/ > [2] > http://stackoverflow.com/questions/5492380/what-is-the-c-iostream-endl-fiasco -- This message was sent by Atlassian JIRA (v6.1#6144)
