I'm writing a program which reads a series of data files as they are dumped into a directory by another process. At the moment, it gets sporadic bugs when it tries to read files which are only partially written.
I'm looking for a function which will tell me if a file is opened in write-mode by another process - if it is, my program will ignore it for now and come back to it later. This needs to work on linux and windows. Mac OS would be a bonus too. An os-independent solution would be good, but I could write os-specific options and have it pick the appropriate one. Is there any way of doing this? I've drawn a blank with google so far. A nasty hack would be to use the file modification time, and wait until that's a few seconds in the past, but is there a nice solution? -- I'm at CAMbridge, not SPAMbridge -- http://mail.python.org/mailman/listinfo/python-list
