Client does not handle paths when copy-tag specified for WU files

[jbk]

Summary: Some applications require files to be in specific directories. When specifying a path in the open_name for a file reference the client will attempt to create a file at that path. This will fail, however, if the path does not exist. (And could be a problem if the path exists but is outside the BOINC directory and if we aren't running in sandbox mode).

Example: ... <file_ref>

<file_number>xyz</file_number> <open_name>directory/filename.file</open_name> <copy_file/>

</file_ref> ...

Current behaviour: 2010-10-23T19:09:38 CEST BuggyProject? [error] Can't copy projects/bugy.project.net/fileXYZ to slots/0/directory/filename.file: fopen() failed

Expected behaviour: That "directory" is created as a subdirectory in slots/0 and that the file is then copied there afterwards.

Solution: Make lib/filesys.cpp::boinc_copy() check whether newf contains a path. If it does then create any missing directories before copying the file.

pseudo code:

int boinc_copy(const char* orig, const char* newf) {

if (newf contains directory seperator){

directory = substr(newf, 0, last occourance of the seperator - 1);

if (!directory exists) boinc_make_dirs(".", directory);

}

...

}
