Remove explicit double quotes from columns.h 'id' entries. The 'id' entries in columns.h are the report field names. Since these are unique, we'd like to use them in generation of 'get' / 'set' functions. As a step towards using them for this purpose, remove the explicit double quotes and use the macro '#' character to add the double quotes back when placing them into the '_fields' array 'id' member.

report: add separate LVSINFOSTATUS field type for info+status combined fields Add separate LVSINFOSTATUS field type for fields which display both dm info-like and dm status-like information. The internal interface is there with the introduction of LVSSTATUS field type which can cope with the combination of LVSSTATUS and LVSINFO field types (several fields). However, till now, we considered that *single* field can display either LVSINFO or LVSSTATUS, but not both at the same time. Till now, we haven't had single field which needs both - hence add LVSINFOSTATUS field type for such fields as we currently need this for the lv_attr field which requires combination of info and status. This patch just adds interface for an ability to register such fields (the code that copes with this is already in).

Add lv_layout_and_type fn, lv_layout and lv_type reporting fields. The lv_layout and lv_type fields together help with LV identification. We can do basic identification using the lv_attr field which provides very condensed view. In contrast to that, the new lv_layout and lv_type fields provide more detialed information on exact layout and type used for LVs. For top-level LVs which are pure types not combined with any other LV types, the lv_layout value is equal to lv_type value. For non-top-level LVs which may be combined with other types, the lv_layout describes the underlying layout used, while the lv_type describes the use/type/usage of the LV. These two new fields are both string lists so selection (-S/--select) criteria can be defined using the list operators easily: [] for strict matching {} for subset matching. For example, let's consider this: $ lvs -a -o name,vg_name,lv_attr,layout,type LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare pool vg twi-a-tz-- pool,thin pool,thin [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tdata_rimage_0] vg iwi-aor--- linear image,raid [pool_tdata_rimage_1] vg iwi-aor--- linear image,raid [pool_tdata_rimage_2] vg iwi-aor--- linear image,raid [pool_tdata_rimage_3] vg iwi-aor--- linear image,raid [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rimage_0] vg iwi-aor--- linear image,raid [pool_tmeta_rimage_1] vg iwi-aor--- linear image,raid [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin thin_vol1 vg Vwi-a-tz-- thin thin thin_vol2 vg Vwi-a-tz-- thin multiple,origin,thin Which is a situation with thin pool, thin volumes and thin snapshots. We can see internal 'pool_tdata' volume that makes up thin pool has actually a level10 raid layout and the internal 'pool_tmeta' has level1 raid layout. Also, we can see that 'thin_snap1' and 'thin_snap2' are both thin snapshots while 'thin_vol1' is thin origin (having multiple snapshots). Such reporting scheme provides much better base for selection criteria in addition to providing more detailed information, for example: $ lvs -a -o name,vg_name,lv_attr,layout,type -S 'type=metadata' LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid (selected all LVs which are related to metadata of any type) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={metadata,thin}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs which hold metadata related to thin) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={thin,snapshot}' LV VG Attr Layout Type thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin (selected all LVs which are thin snapshots) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout=raid' LV VG Attr Layout Type [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid layout, any raid layout) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout={raid,level1}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid level1 layout exactly) And so on...

lvm2app: Add signed numerical property values Currently lvm2app properties have the following structure: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t padding:28; union { const char *string; uint64_t integer; } value; } lvm_property_value_t; which assumes that numerical values were in the range of 0 to 2**64-1. However, some of the properties were 'signed', like LV major/minor numbers and some reserved values for properties that represent percentages. Thus when the values were retrieved they were in two's complement notation. So for a -1 major number the API user would get a value of 18446744073709551615. The API user could cast the returned value to an int64_t to handle this, but that requires the API developer to look at the source code and determine when it should be done. This change modifies the return property structure to: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t is_signed:1; uint32_t padding:27; union { const char *string; uint64_t integer; int64_t signed_integer; } value; } lvm_property_value_t; With this addition the API user can interrogate that the value is numerical, (is_integer = 1) and subsequently check if it's signed (is_signed = 1) too. If signed, then the API developer should use the union's signed_integer to avoid casting. This change maintains backwards compatibility as the structure size remains unchanged and integer value remains unchanged. Only the additional bit taken from the pad is utilized.

lvm2app: Add signed numerical property values Currently lvm2app properties have the following structure: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t padding:28; union { const char *string; uint64_t integer; } value; } lvm_property_value_t; which assumes that numerical values were in the range of 0 to 2**64-1. However, some of the properties were 'signed', like LV major/minor numbers and some reserved values for properties that represent percentages. Thus when the values were retrieved they were in two's complement notation. So for a -1 major number the API user would get a value of 18446744073709551615. The API user could cast the returned value to an int64_t to handle this, but that requires the API developer to look at the source code and determine when it should be done. This change modifies the return property structure to: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t is_signed:1; uint32_t padding:27; union { const char *string; uint64_t integer; int64_t signed_integer; } value; } lvm_property_value_t; With this addition the API user can interrogate that the value is numerical, (is_integer = 1) and subsequently check if it's signed (is_signed = 1) too. If signed, then the API developer should use the union's signed_integer to avoid casting. This change maintains backwards compatibility as the structure size remains unchanged and integer value remains unchanged. Only the additional bit taken from the pad is utilized.

report: use same info also for lv_attr Recently the single 'status' code has been used for number of cache features. Extend the API a little bit to allow usage also for lv_attr_dup. As the function itself is used in lvm2api - add a new function: lv_attr_dup_with_info_and_seg_status() that is able to use grabbed info & status information. report_init() is now using directly passed lvdm struct pointer which holds the infomation whether lv_info() was correctly obtained or there was some error when trying to read it.

Remove explicit double quotes from columns.h 'id' entries. The 'id' entries in columns.h are the report field names. Since these are unique, we'd like to use them in generation of 'get' / 'set' functions. As a step towards using them for this purpose, remove the explicit double quotes and use the macro '#' character to add the double quotes back when placing them into the '_fields' array 'id' member.

cache: include cache mode in vg metadata and display The cache mode of a new cache pool is always explicitly included in the vg metadata. If a cache mode is not specified on the command line, the cache mode is taken from lvm.conf allocation/cache_pool_cachemode, which defaults to "writethrough". The cache mode can be displayed with lvs -o+cachemode.

report: define ba_start, vg_free and seg_start fields as DM_REPORT_FIELD_TYPE_SIZE instead of DM_REPORT_FIELD_TYPE_NUM This makes a difference when using selection criteria based on these fields - if those fields are defined as DM_REPORT_FIELD_TYPE_SIZE (in contrast to DM_REPORT_FIELD_TYPE_NUMBER), units are also recognize in selection clause. For example: $ lvs -o+seg_start vg1/lv2 LV VG Attr LSize Start lv2 vg1 -wi-a----- 12.00m 0 lv2 vg1 -wi-a----- 12.00m 8.00m Before this patch: $ lvs -o+seg_start --select 'seg_start=8m' Found size unit specifier but numeric value expected for selection field seg_start. Selection syntax error at 'seg_start=8m'. Use 'help' for selection to get more help. With this patch applied: $lvs -o+seg_start --select 'seg_start=8m' LV VG Attr LSize Start lv2 vg1 -wi-a----- 12.00m 8.00m (the same applies for ba_start and vg_free fields)
