RE: libquota-devel - broken incomplete package ?
Hello! I now have a working solution, but... this is Windows! - Quotas only work on NTFS. Not even the newer ReFS supports them. - Quotas only work for users, not for groups. You can add groups to the filesystem's quota file (not via the GUI, btw), but they are simply ignored because their QuotaUsed is always 0. - Quotas for inodes obviously won't work. - Quota time limits are not supported at all. Well... At least we can do what we can. I think it still makes sense, because now we have quota support. Yes, on Windows quotas are different from e.g. Linux, but i guess on different UNIX flavors (Linux vs BSD for example) they are also not supposed to work in the same way.

Sorry, Cygwin doesn't support quota management yet.
It can be added relatively easily, AFAICS.
I spoke too soon. This is Windows after all...
There are two ntdll system
calls Nt{Query,Set}QuotaInformationFile and a Nt{Query|Set}InformationFile
info class FILE_FS_CONTROL_INFORMATION to switch quoat mgmg on and off,
which roughly provide the functionality of quotactl, at least as far as
the block quota is concerned. Windows doesn't support inode-based or
time limit-based quota management.
We can look into implementing this at one point, and patches are
welcome, of course.
I made a first attempt to implement a quotactl function, and failed:

ignored because their QuotaUsed is always 0.

So all we can do is switching quotas on NTFS on or off, and setting and
getting user's block quotas.
Is that really worth it?

libquota-devel - broken incomplete package ?
Hello!
I am trying to build NFS-Ganesha, and it includes rquota protocol support,
which relies on USRQUOTA and GRPQUOTA definitions.
After some searching i have found libquota-devel package which should
apparently be responsible for these. However, inside its only include file i
read the following comments:
--- cut ---
* The typical way to use the quota library is as follows:
* {
* quota_ctx_t qctx;
*
* quota_init_context(qctx, fs, -1);
* {
* quota_compute_usage(qctx, -1);
* AND/OR
* quota_data_add/quota_data_sub/quota_data_inodes();
* }
* quota_write_inode(qctx, USRQUOTA);
* quota_write_inode(qctx, GRPQUOTA);
* quota_release_context(qctx);
* }
--- cut ---
quota_write_inode() declaration is present, however USRQUOTA and GRPQUOTA
are entirely missing. Even more suspicious thing is include files:
--- cut ---
#include ext2fs/ext2_fs.h
#include ext2fs/ext2fs.h
#include quotaio.h
#include ../e2fsck/dict.h
--- cut ---
quotaio.h is completely missing in /usr/include. What's wrong ? Is the
package utterly broken ?
BTW, just for interest, does Cygwin actually support quotas ? NT OS should
actually support them i guess...

maybe as it reported only in the debug source
