Why ? Isn't that standard behavior/semantics: unless you flush you cannot be sure anything is actually out of the OS' buffers. And even then, disks and RAID cards are known to lie and sometimes don't write data out even when flush is called. In networking (TCP streams) this is similar. >> Cheers, >> -- Pavel >> >> >> On Fri, Apr 26, 2013 at 9:57 AM, GOUBIER Thierry <thierry.goub...@cea.fr> >> wrote: >>> >>> Reproduced on Ubuntu 13.04. >>> >>> Class organization remoteString filePositionHi is past the end of the >>> changes file (i.e. exactly equal to the file size if the comment is the last >>> operation). >>> >>> Thierry >>> ________________________________ >>> De : pharo-project-boun...@lists.gforge.inria.fr >>> [pharo-project-boun...@lists.gforge.inria.fr] de la part de Pavel Krivanek >>> [pavel.kriva...@gmail.com] >>> Date d'envoi : jeudi 25 avril 2013 21:32 >>> À : Pharo-project@lists.gforge.inria.fr >>> Objet : Re: [Pharo-project] cannot modify class comments on Linux >>> >>> Jaroslav wrote this: >>> This does work on F17, but it doesn't work on F18, F19.
