It was necessary to ensure that ``stat(x)'' and ``chdir(x);stat(".")'' returned exactly the same st_dev and st_ino. Thus the open() function and the stat() family now mkdir_between at strategic times. It was necessary to ensure that st_nlink was at least al large as the aparrent number of directories. We did this by adding all the st_nlinks together (subtracting 2 carefully). This may be too big, but that's OK because find short circuits incorrectly only when it's too small.

(The getdents and getdents64 symbols are not exported by Project "plasticfs.1", Branch 0 Page 19 Change Log Wed Nov 28 09:11:17 2007 the libc.so.6 shared library. It would have been much simpler of GNU libc exported the getdents and getdents64 symbols, then we could have used the GNU libc implementation of the opendir family of calls. As it is, we have to emulate this family of calls. plasticfs.1.0.D018, C15, pmiller, Mon Dec 23 09:16:15 2002, view filter, open This change adds the viewpath filter class, only the open method is implemented so far. plasticfs.1.0.D017, C32, pmiller, Mon Dec 23 09:07:31 2002, lseek intercept This change adds the intercept for the lseek system call. plasticfs.1.0.D016, C33, pmiller, Mon Dec 23 08:34:00 2002, get types right This change corrects the types used in a number of the method declarations. plasticfs.1.0.D015, C29, pmiller, Sat Dec 21 17:40:35 2002, namespace, again This change refines the use of namespaces. plasticfs.1.0.D014, C28, pmiller, Sat Dec 21 17:01:46 2002, simplify some intercepts This change simplifies the open, close, reand and write intercepts, now that I know better what to do. plasticfs.1.0.D013, C27, pmiller, Sat Dec 21 16:35:56 2002, stat intercept This change adds the stat intercepts. plasticfs.1.0.D012, C26, pmiller, Sat Dec 21 09:57:53 2002, rcstring_list class This change adds the rcstring_list class, so that we don't have to use templates. plasticfs.1.0.D011, C22, pmiller, Fri Dec 20 23:05:17 2002, rcstring class This change adds the rcsting (reference counted string) class. plasticfs.1.0.D010, C23, pmiller, Fri Dec 20 22:01:47 2002, namespace libplasticfs This change adds the use of the libplastics name space, which insulates other C++ programs from the symbols using in our library. plasticfs.1.0.D009, C25, pmiller, Fri Dec 20 21:39:45 2002, errno insulator This change adds the errno insulator class. plasticfs.1.0.D008, C16, pmiller, Fri Dec 20 20:37:07 2002, readlink intercept This change adds the readlink methods and intercept. plasticfs.1.0.D007, C21, pmiller, Fri Dec 20 07:30:33 2002, open64 intercept This change adds the open64 intercept. plasticfs.1.0.D006, C19, pmiller, Fri Dec 20 07:13:14 2002, creat intercept This change adds the creat intercept.

It isn't actually used. plasticfs.1.0.D004, C17, pmiller, Fri Dec 20 07:06:23 2002, build problems This change fixes a build problem. It seems if you build a shared library from .lo files which have moved directory (e.g. integration dir moving to be baseline) them the resultinjg .so file will make dlsym() segfault. plasticfs.1.0.D003, C12, pmiller, Thu Dec 12 23:17:17 2002, log filter This change adds a file access log filter. plasticfs.1.0.D002, C11, pmiller, Wed Dec 11 22:19:39 2002, the pass through class This change adds the dlsym rtld next class, to pass calls through to the next shared library. plasticfs.1.0.D001, C10, pmiller, Mon Dec 9 16:51:44 2002, initial skeleton This change forms the initial skeleton of the project.
