Race file

Are you talking about the consistency of internal kernel datastructures, or the view of file content from user land? Add a comment. Active Oldest Votes. But pay particular attention to the specification for write bolding mine : The write function shall attempt to write nbyte bytes Improve this answer. Andrew Henle Andrew Henle There are two scenarios: The regions written to do not overlap.

There is no race condition in this case. The regions written to do overlap. Userspace programs have at least four different methods to avoid such races: Advisory file locks on the entire open file using the flock interface.

Stack Gives Back We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats.

We'd love hearing from you if you have information about the format. You will need a program compatible with the specific file you are trying to open, as different programs may use files with file extension TRACE for different purposes. While we have not verified the apps ourselves yet, our users have suggested 4 different TRACE openers which you will find listed below. The Census Bureau does not release bridged-race estimates by single year of age at the county level due to concerns about the reliability of these estimates.

NOTE: Vintage estimates have been superseded by the Intercensal estimates and are retained on this site solely for historical purposes. County data files for ages 0 to 85 These data files have the bridged-race estimates of the resident population of the United States as enumerated on April 1,, by county, single-year of age 0, 1, 2, …, 85 years and over , bridged race White, Black or African American, American Indian or Alaska Native, Asian or Pacific Islander , Hispanic origin not Hispanic or Latino, Hispanic or Latino , and sex.

The county, State, and national single-year of age intercensal files below replaced the county-level single-year of age intercensal files previously released on April 30, because the files originally released contained some -1 population counts see file documentation for explanation. The bridged-race intercensal estimates for on this Web site differ from the estimates released on the NCI Web siteexternal icon external icon.

The Epidemiology Program of the Hawaii Cancer Research Center has developed their own set of population estimates, based on sample survey data collected by the Hawaii Department of Health. This effort grew out of a concern that the native Hawaiian population has been vastly undercounted in previous censuses. This program typically prints , not The program can be fixed by making a copy of the variable:. If the following code is called from several goroutines, it leads to races on the service map.

Concurrent reads and writes of the same map are not safe:. Data races can happen on variables of primitive types as well bool , int , int64 , etc. Even such "innocent" data races can lead to hard-to-debug problems caused by non-atomicity of the memory accesses, interference with compiler optimizations, or reordering issues accessing processor memory. A typical fix for this race is to use a channel or a mutex.
