Function Documentation

gboolean free_namesize_kv (  gpointer  key, gpointer  unused_value, gpointer  unused_udata )  [static]

Remove iterator callback. Free a key/value pair from the by_namesize hash.

gboolean free_sha1_kv (  gpointer  key, gpointer  value, gpointer  unused_udata )  [static]

Remove iterator callback. Free a key/value pair from the by_sha1 hash.

void ignore_add_filesize (  const gchar *  file, filesize_t  size )

Add `file', `size' to the set of ignored entries.

void ignore_add_sha1 (  const gchar *  file, const gchar *  sha1 )

Add `sha1' to the set of ignored entries.

void ignore_close (  void   )

Called during servent shutdown to free up resources.

void ignore_init (  void   )

Initialize the ignore tables.

enum ignore_val ignore_is_requested (  const gchar *  file, filesize_t  size, gchar *  sha1 )

Is ignoring requested for `file' of size `size' and SHA1 `sha1'? Priority is given to the SHA1, if supplied. Parameters: file  Must be a basename, without any directory separator size  the filesize sha1  must point to a SHA1 (binary) or NULL

void ignore_namesize_load (  const gchar *  file, time_t *  stamp )  [static]

Load new name/size tuples from `file'. If `stamp' is non-NULL, fill it with the mtime of the file, or the current time if the file does not exist.

gchar* ignore_sha1_filename (  const gchar *  sha1  )

Returns: the filename associated with the digest if known, NULL otherwise.

void ignore_sha1_load (  const gchar *  file, time_t *  stamp )  [static]

Load new SHA1 from `file'. If `stamp' is non-NULL, fill it with the mtime of the file, or the current time if the file does not exist.

void ignore_timer (  time_t  unused_now  )

Called periodically to check the file timestamps. If files are newer, they are reloaded, but the previously recorded ignores are NOT forgotten. Therefore, we can ONLY append new ignores.

void namesize_parse (  FILE *  f, const gchar *  file )  [static]

Parse opened `f' containing size/filenames to ignore.

FILE* open_append (  const gchar *  file  )  [static]

Open `file' for appending.

FILE* open_read_stamp (  const gchar *  file, time_t *  stamp )  [static]

Open `file' for reading if it exists. If `stamp' is non-NULL, fill it with the mtime of the file, or the current time if the file does not exist. Returns: FILE* of the opened file on success, NULL on failure.

RCSID (  "$Id:ignore.  c, v 1.15 2005/12/27 16:34:49 cbiere Exp $"  )

void sha1_parse (  FILE *  f, const gchar *  file )  [static]

Parse opened file `f' containing SHA1s to ignore.
