quota-count: Remove extra "quota-count failed:" from error_r

Updated copyright notices to include the year 2018.

quota: Prefix quota errors with backend name in quota_get_resource() Remove quota backend name error_r prefixing from get_resource() vfuncs.

quota: Add error_result_r parameter to quota_count()

quota: Return quota_get_result from quota_backend_vfuncs.get_resource() Add a QUOTA_UNKNOWN_RESOURCE_ERROR_STRING for returning error_r with QUOTA_GET_RESULT_UNKNOWN_RESOURCE. Forbid backends from returning QUOTA_GET_RESULT_UNLIMITED in quota_get_resource() with an i_panic().

quota-count: Improve error_r strings

quota: Add error_r to update() of quota_backend_vfuncs

quota: Add error_r to get_resource() of quota_backend_vfuncs

quota: Initialize quota_backends with designated initializers

quota: count backend - Don't ignore mailbox list iteration errors

global: Add mailbox_set_reason() calls Added to the most important places.

global: Log internal storage error on failure

global: Log mailbox_list internal errors

lib-storage: Add mail_vsize_bg_after_count setting. If folder vsize calculation requires opening more than this many mails from disk (i.e. mail sizes aren't in cache already), return failure and finish the calculation via indexer process. This should be used like: protocol !indexer-worker { mail_vsize_bg_after_count = 10 }

quota: Clarify quota_count() return value.

Updated copyright notices to include the year 2017.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

quota: Differentiate between forced and non-forced quota recalc The "count" backend doesn't need to recalc quota unless an explicit "doveadm quota recalc" command is called.

quota: Skip reading mail sizes when quota backend doesn't need it. If quota backend is updating the quota internally, it's just going to ignore the looked up size. The only reason for looking up the sizes is to check with quota_try_alloc() whether user is going over quota.

quota: dict-quota was broken by 464db6d9d We can't assume that the quota_root given to quota_count() is count_quota_root, because dict_quota_root also calls it.

quota-count: Cache quota usage within the same ioloop run. This mainly means that when both STORAGE and MESSAGES quota is looked up we don't need to calculate them twice.

quota-count: Code cleanup - give consistent return value Although the callers didn't care if it returned 0 or 1.

quota: Fixed namespace filtering for dict and count backends.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

quota: When recalculating quota, don't try to access nonexistent autocreate-mailboxes. There's no need to physically create them, since they're empty anyway.

quota: Fix to previous commit - counting quota-disabled-storages may have returned random failures.

quota: Fixed "count" backend to ignore storages that have quota disabled. For example virtual mailboxes shouldn't be counted in quota.

quota: The new quota counting code was counting only the last mailbox.

quota: doveadm quota recalc works now for "count" backend by rebuilding vsize header.

quota: Code cleanup - abstract out iteration of mailboxes related to a quota root.

quota: Added "count" backend, which simply sums up mailboxes' vsizes. In a way this is similar to the simple "dirsize" backend, but much more efficient. As long as mailbox_list_index=yes, the quota can typically be looked up only by reading the dovecot.list.index* files. This backend enforces using quota_vsizes=yes setting to keep the performance good, because physical sizes don't have a similar optimized vsize header. There's also no especially good reason why this backend should support physical sizes - they were originally mainly used to allow quickly stat()ing Maildir files.

quota: Added quota_vsizes=yes setting to count quotas using virtual sizes instead of physical sizes. This doesn't work with all the quota backends.

quota: Use MAILBOX_METADATA_PHYSICAL_SIZE for recalculating mailbox's size.

quota: Even if quota counting fails, commit the mailbox transaction. The only changes in the transaction are changes to dovecot.index.cache file and we don't want to rollback those.

quota: Fixed error handling in quota counting code. Errors weren't logged and some error checking was missing.
