Detailed Description

Common ancestor of SQL statemnts that deal with directory entries.

Definition at line 174 of file catalog_sql.h.

Member Function Documentation

unsigned catalog::SqlDirent::CreateDatabaseFlags ( const DirectoryEntry entry) const
protected

Take the meta data from the DirectoryEntry and transform it into a valid flags field ready to be saved in the database.

Parameters
entrythe DirectoryEntry to encode
Returns
an integer containing the bitmap of the flags field

Definition at line 417 of file catalog_sql.cc.

Here is the call graph for this function:

void catalog::SqlDirent::ExpandSymlink ( LinkString raw_symlink) const
protected

Replaces place holder variables in a symbolic link by actual path elements.

Parameters
raw_symlinkthe raw symlink path (may) containing place holders
Returns
the expanded symlink

Expands variant symlinks containing string. Uses the environment variables of the current process (cvmfs2)

Definition at line 504 of file catalog_sql.cc.

Here is the call graph for this function:

uint32_t catalog::SqlDirent::Hardlinks2HardlinkGroup ( const uint64_t  hardlinks) const
protected

Definition at line 487 of file catalog_sql.cc.

uint32_t catalog::SqlDirent::Hardlinks2Linkcount ( const uint64_t  hardlinks) const
protected

The hardlink information (hardlink group ID and linkcount) is saved in one uint_64t field in the CVMFS Catalogs. Therefore we need to do bitshifting in these helper methods.

const uint32_t  linkcount

Member Data Documentation

const int catalog::SqlDirent::kFlagDirBindMountpoint = 0x4000
static

A transition point to a root catalog (instead of a nested catalog). Used to link previous snapshots into the catalog structure.

Definition at line 207 of file catalog_sql.h.

const int catalog::SqlDirent::kFlagDirectIo = 0x10000
static

For regular files, indicates that the file should be opened with direct I/O

Definition at line 216 of file catalog_sql.h.

const int catalog::SqlDirent::kFlagDirNestedMountpoint = 2
static

Definition at line 180 of file catalog_sql.h.

const int catalog::SqlDirent::kFlagDirNestedRoot = 32
static

Definition at line 182 of file catalog_sql.h.

const int catalog::SqlDirent::kFlagFileExternal = 128
static

The file is not natively stored in cvmfs but on a different storage system, for instance on HTTPS data federation services. NOTE: used as magic number in SqlListContentHashes::SqlListContentHashes
