Functions | |
bool | FileCommit (FILE *file) |
Ensure file contents are fully committed to disk, using a platform-specific feature analogous to fsync(). More... | |
void | DirectoryCommit (const fs::path &dirname) |
Sync directory contents. More... | |
bool | TruncateFile (FILE *file, unsigned int length) |
int | RaiseFileDescriptorLimit (int nMinFD) |
This function tries to raise the file descriptor limit to the requested number. More... | |
void | AllocateFileRange (FILE *file, unsigned int offset, unsigned int length) |
This function tries to make a particular range of a file allocated (corresponding to disk space) it is advisory, and the range specified in the arguments will never contain live data. More... | |

void AllocateFileRange | ( | FILE * | file, |
unsigned int | offset, | ||
unsigned int | length | ||
) |
This function tries to make a particular range of a file allocated (corresponding to disk space) it is advisory, and the range specified in the arguments will never contain live data.

bool CheckDiskSpace | ( | const fs::path & | dir, |
uint64_t | additional_bytes = 0 |
||
) |
void DirectoryCommit | ( | const fs::path & | dirname | ) |
Sync directory contents.
This is required on some environments to ensure that newly created files are committed to disk.

bool DirIsWritable | ( | const fs::path & | directory | ) |
Definition at line 97 of file fs_helpers.cpp.
bool FileCommit | ( | FILE * | file | ) |
Ensure file contents are fully committed to disk, using a platform-specific feature analogous to fsync().
Definition at line 125 of file fs_helpers.cpp.
fs::path GetDefaultDataDir | ( | ) |
std::streampos GetFileSize | ( | const char * | path, |
std::streamsize | max = std::numeric_limits< std::streamsize >::max() |
||
) |
Get the size of a file by scanning it.
[in] | path | The file path |
[in] | max | Stop seeking beyond this limit |

bool LockDirectory | ( | const fs::path & | directory, |
const std::string | lockfile_name, | ||
bool | probe_only = false |
||
) |

int RaiseFileDescriptorLimit | ( | int | nMinFD | ) |
This function tries to raise the file descriptor limit to the requested number.
It returns the actual file descriptor limit (which may be more or less than nMinFD)
Definition at line 182 of file fs_helpers.cpp.
void ReleaseDirectoryLocks | ( | ) |
Release all directory locks.
This is used for unit testing only, at runtime the global destructor will take care of the locks.
Definition at line 92 of file fs_helpers.cpp.
bool TruncateFile | ( | FILE * | file, |
unsigned int | length | ||
) |
bool TryCreateDirectories | ( | const fs::path & | p | ) |
Ignores exceptions thrown by create_directories if the requested directory exists.
Specifically handles case where path p exists, but it wasn't possible for the user to write to the parent directory.

void UnlockDirectory | ( | const fs::path & | directory, |
const std::string & | lockfile_name | ||
