it must be independed from sync_external_file because sync often does not actually download contents, it is used just to retrieve
the size of the file. Besides the timeouts for get_file and sync requests are very different.
Also add option to send_stored_file() to ignore reference and send cached contents
- When several records in {files} have the same record in {files_reference} and the synchronisation is performed, we need to update
all records in {files} so all files know if source is changed and that sync was performed;
- also when local moodle file content is changed we immediately update all files referencing to it (therefore sync of references
to the local files is unnecessary);
Initially it was not clear enough that these two methods are supposed to
be used for looking for references to a stored_file only. So the docs
comments are improved and unittests added to illustrate the usage.
The patch also removes the unittest for get_references_by_storedfile()
as its usage is already covered in other test methods.
- do not die with fatal error if source file in moodle internal repository is missing;
- moved code duplication for moodle repositories into class repository (functions send_file, get_reference_details, get_file_by_reference, get_file_reference);
- update file status after repository::sync_external_file so we know that it is missing (or not missing anymore). Do not run this function more than once for file within one request;
- display readable name for Private Files and Server files with the new format;
- display broken icon in filemanager if we know that source is missing, display information (for admin) where it was located before: see repository::get_reference_details() and extending classes;
- removed unnecessary queries in stored_file::sync_external_file();
- syncronize files before displaying it's size in mod_resource, do not query directly
The first unit test forces the File API to be more picky as any sane
core API should be. The second one illustrates the buggy behaviour of
the current implementation of delete_reference(). They both fail at the
moment, of course...
Together with this, refactoring and cleanup of search_references() and
similar methods was done. SQL was improved to use the INNER JOIN instead
of the LEFT JOIN as we are really interested in records that have a
reference. Also, joining the {repository_instances} table assures that
only references with valid repository_instance are returned (the check
against is_external_file() can't be applied to the methods that return
the count of references so I dropped it completely).
This patch unifies the way how records in {files_reference} get created.
Previously, each reference file (i.e. a file with referencefileid set)
created its own record in {files_reference}. This patch makes sure that
existing record is reused if possible.
Bye bye 1:1 relationships, you suck!
This replaces the previously defined external_file_exception that was
not used anywhere in the code. The new exception will be thrown in
situations where there is some unexpected problem detected with the
records in the {files_reference} table (e.g. unable to find a record
referenced by some file from {file}, invalid reference value etc.)
- when file is uploaded in php, the tmpname does not have initial extension and mimetype recognition by extension fails
- another issue is that import form for questions fails with fatal error when it should just say that field is required
Fixes the following problems:
* When we select from two tables with the same named fields (id)
and ask to sort by that field, Oracle doesn't know which table to
sort frm unless that field is named in the SELECT. Here we do that
by explicitly naming the fields. This keeps compatibility with before
the reference table was added.
* Text comparisong without sql_compare_text
- use finfo to determine mimetype of a file only when it is unknown from file extension
- display filetype icon and mimetype in filemanager based on file extension
- fixed a small issue with specifying extension instead of group in file_get_typegroup()
- allow only web-compartible image types when embedding into editor or using in database field
- created new groups web_video and web_audio to use in resource module
- function get_mimetypes_array() now contains also information about filetype groups and language strings
- use 'smart' human-readable mimetype description
- never determine filetype group based on filetype icon image! remove function mimeinfo_from_icon()
- get rid of class filetype_parser and file lib/filestorage/file_types.mm, replaced with functions file_get_typegroup(), file_extension_in_typegroup() and file_mimetype_in_typegroup()
- support multiple icon sizes, not only 16 and 32
- retrieve filetype icon only using proper functions file_..._icon() from lib/filelib.php throughout the code
- increase size of repository thumbnails to 90 and icons to 24 (will take effect when new icons exist)
