Drupal search_files.module-1.18.thl.1

Unsure whether I'd open a dozened issues or one summary. Unfortunately enhancements and fixes for some issues overlap in one hunk, so cherrypicking cannot be blindly done using a hunk by hunk approach.

Details see http://www.lotterer.net/blog/en/165-drupal-search_filesmodule-118thl1
Patch see http://www.lotterer.net/thomas/drupal/search_files.module-1.18-1.18.thl....

Changes between Drupal search_files 1.18 and 1.18.thl.1

* feature
added dashboard as default local task to search_files menu to allow some status insight (ugly but useful)
Hunks at original line 16 and 557

* cleanup
manually deleting a directory clears associated data from search_dataset, search_files_files, search_files_directories tables in a single SQL statement. Create and leverage function search_files_delete_content_by_directory_fullpath() to complement similar new but automatically called function search_files_delete_content_by_file_fullpath();
Hunk at original line 178

* feature
detect PHP safe_mode, display status in dashboard and skip over shell_exec() which would fail anyway.
At the end of hunk at original line 178 and in hung at original line 584

* feature
do not confuse users with trailing slash issues.
Hunks at original line 228 and 314

* feature
print current working directory and turn relative pathes into absolute pathes
Hunks at original line 228 and 314

* typo
funciton -> function
At the end of hunk at original line 557

* feature
turn hardcoded “Directory Rescan Age” into a configurable parameter
Hunk at original line 568 and start of hunk at original line 584

* bugfix
configuration of “Search Label” must use #default_value not #value
Hunk at original line 568

* bugfix
there is a functional gap where vanished files were not handled at all. Regularly compare database to filesystem and remove vanished files from database.
Hunk at original line 584

* bugfix
while indexing files, skip over files which vanished before being indexed. Otherwise helper applications will get passed a nonexistent file name and fail.
Hunk at original line 640

* cleanup
remove debugging
Hunk at original line 715

* bugfix
while preparing search results, skip over files which vanished after being indexed. Otherwise functions like filectime() will get passed a nonexistent file name and fail.
Hunk at original line 812
