Chalten: Month and Year Units

by Sean P. DeNigris

I guess they aren't derived from each other because e.g. the Hebrew calendar has leap months. But doesn't that just mean that "Month" is representing two incompatible distinctions? It seems we should be able to distinguish "1 gregorianYear = 12 gregorianMonths" from "1 hebrewYear convertTo: months" which is an invalid question. Right now, one can't ask "1 yearMeaure / 12 monthsMeaure" and get 1 ----- Cheers, Sean -- View this message in context: http://forum.world.st/Chalten-Month-and-Year-Units-tp4813273.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Get OS uptime

by Michal Balda

Hi, your solution does not work because files in /proc are virtual and have no size (their size will be reported as 0). FileStream>>contents sends #size to determine the length and that will return 0 for all files in /proc. So the solution is to use something that does not use #size, like: (FileLocator root / 'proc' / 'uptime') readStream upToEnd Michal On 19.3.2015 07:07, Julien Delplanque wrote: > Hi everyone, > > I can't find out how to get the uptime of the OS from pharo. > > I tried: > > (FileLocator root / 'proc' / 'uptime') readStream contents. > > and > > (FileSystem disk root / 'proc' / 'uptime') readStream contents. > > but all what I get is an empty string ''. > > I don't know if there are messages in some specific classes to do this > (in OSProcess for example?). > > Thanks in advance. > > Julien >

So I still not understand the problem. files in /proc are not seekable. that or something related may be the problem. compare this strace: /proc/uptime: lstat64("/proc/uptime", {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 open("/proc/uptime", O_RDONLY) = 8 fstat64(8, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xfffffffff722e000 fstat64(8, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 _llseek(8, 0, [0], SEEK_SET) = 0 _llseek(8, 0, [0], SEEK_SET) = 0 _llseek(8, 0, [0], SEEK_SET) = 0 _llseek(8, 0, [0], SEEK_SET) = 0 close(8) = 0 /etc/profile: lstat64("/etc/profile", {st_mode=S_IFREG|0644, st_size=1750, ...}) = 0 open("/etc/profile", O_RDONLY) = 8 fstat64(8, {st_mode=S_IFREG|0644, st_size=1750, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xfffffffff722e000 fstat64(8, {st_mode=S_IFREG|0644, st_size=1750, ...}) = 0 _llseek(8, 0, [0], SEEK_SET) = 0 read(8, "# /etc/profile\n\n# System wide en"..., 1750) = 1750 _llseek(8, 1750, [1750], SEEK_SET) = 0 _llseek(8, 1750, [1750], SEEK_SET) = 0 read(8, "", 4096) = 0 _llseek(8, 0, [0], SEEK_SET) = 0 close(8) = 0 /proc/uptime comes with a filesize of 0, and this, pharo tries to read 0 bytes from it. or rather, since there is no read() call, it concludes that there is nothing to read. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

It's sometimes referred to as a process information pseudo-file system. It doesn't contain 'real' files but runtime system information (e.g. system memory, devices mounted, hardware configuration, etc). For this reason it can be regarded as a control and information centre for the kernel.

Or better I like to know how the plugin can distinguish them. Usually there shouldn't be a difference. I know the /proc filesystem. It is what unix is all about. Make every information available as file. You say it is a virtual filesystem? Yes, but there are only virtual filesystems in linux.
