In the file \lib\Support\Process.cpp on line 60, it seems as though an unnecessary heap allocation and memory leak occurs. This is the offending code: static TimeValue getElapsedWallTime() { static TimeValue &StartTime = *new TimeValue(TimeValue::now()); return TimeValue::now() - StartTime; } The issue is that the StartTime variable's value is allocated on the heap, after which a

Hi, Is it necessary to use the VC6.1+ `__time64_t' type instead of __time_t in win32/TimeValue.cpp? --------------- In file included from c:/projects/src/llvm-1/llvm/lib/System/TimeValue.cpp:51: c:/projects/build/MinGW/llvm-1-1/lib/System/platform/TimeValue.cpp: In member function `std::string llvm::sys::TimeValue::toString() const':

I'm not sure. Perhaps Jeff Cohen knows as he wrote this. Reid.

Replace __time_t with time_t in my question. I've compiled function: std::string TimeValue::toString() const { // Alas, asctime is not re-entrant on Windows... //hb: __time64_t ourTime = this->toEpochTime(); time_t ourTime = this->toEpochTime(); //hb: char* buffer = ::asctime(::_localtime64(&ourTime)); char* buffer = ::asctime(::localtime(&ourTime)); std::string

Hi Reid, You've got a TimeValue.cpp which it looks like you just added to lib/System, but I can't compile it on Darwin because there's no Darwin/TimeValue.cpp. This breaks my ppc build. I'm not sure what TimeValue was supposed to be for, so I just blew it away in my tree. Please take a look at this. -Brian -- gaeke at uiuc.edu

This should be fixed. Sorry for the breakage. I forgot to commit a bunch of files. Reid. On Fri, 2004-09-24 at 20:33, Brian R.

Dear list-members, I would like to calculate the difference between two points in time. To convert a 'time (GMT)'-character with the format "1/1/1999 01:01:01" into an object of class "POSIXct"', I first use the strptime() as suggested in the details help(as.POSIXct). e.g. starttime<-strptime("1/1/1999 01:01:01",format="%d/%m/%Y %H:%M:%S")

I am having trouble with creating a POSIXct object. If I create a variable of class Date first out of the date part of my data, I am ok, but if I just paste the date and time parts together and try and create the POSIXct object, I have problems. Here is a toy example created from the actual data which caused the problem. I am using R 2.0.1 on Windows XP. > # Data frame with dates and

Greetings, I have a csv file of 76 fields and about 4 million records. I know that some of the records have errors - unmatched quotes, specifically.? Reading the file with readLines and parsing the lines with read.csv(text = ...) is really slow. I know that the first 2459465 records are good. So I try this: > startTime <- Sys.time() > first_records <- read.csv(file_name, nrows

Hi everyone I want to apply a function by two indices. I have a number of surveyors submitting questionnaires. I want to check the time of the first submission for the day for each surveyor and also see a NA is no submission was done on a particular day. This generates a sample of the data:

If you're getting this error in lib/System/Win32/TimeValue.cpp, then you are not building it correctly. This file is included by lib/System/TimeValue.cpp, which is what you ought to be building. None of the files under Win32 are to be compiled directly; they are all included by files in lib/System. On Mon, 01 Nov 2004 11:14:18 +0100 Morten Ofstad <morten at hue.no> wrote: > Hello,

Hi Dave, That's rather frustrating. I've found vroom (from the package vroom) to be helpful with large files like this. Does the following give you any better luck? vroom(file_name, delim = ",", skip = 2459465, n_max = 5) Of course, when you know you've got errors & the files are big like that it can take a bit of work resolving things. The command line tools awk

No idea, but have you tried using ?scan to read those next 5 rows? It might give you a better idea of the pathologies that are causing problems. For example, an unmatched quote might result in some huge number of characters trying to be read into a single element of a character variable. As your previous respondent said, resolving such problems can be a challenge. Cheers, Bert On Mon, Apr 8,

Hi, My question is a bit of wonder and a bit of enlightment. I have two models, Channel and ChannelItem, the second is a list of Events, ordered by position (because I''m using acts_as_list). Later I use a method in Channel to recalculate the hour when that show come online, based on the duration of it and doing math based on the previous one duration and start time, starting from

I'm trying to get clang 3.6.1 to compile itself on Windows, using this command line: msbuild /p:Configuration=Release /p:CLToolExe=clang-cl.exe /p:CLToolPath=c:\llvm\build\Release\bin\ /p:TrackFileAccess=false /p:Platform="x64" /fileLogger ALL_BUILD.vcxproj It barfed on an occurrence of __try but that was only in a test file so I commented it out and retried. Now it's getting

data.table's fread is also fast. Not sure about error handling.

Hi, Suppose I have a model class which has a time field: class CreateAppointments < ActiveRecord::Migration def change create_table :appointments do |t| t.string :name t.datetime :startTime t.datetime :endTime t.string :description t.timestamps end end end When I test drive it in rails console, I can input any value int he startTime and endTime such

I have two local variables: startTime and expectedStartTime. Both are chron related objects. When I look at the class for the objects I can see they are of class "times". When I print them to the console, they both read: "09:30:00" When I print them as.numeric(), they both read: 0.3958333 When I try and compare them: (as.numeric(startTime) == as.numeric(expectedStartTime)) it
