We now abstract the actual file generation to a new function.
We are then able to call this function from the other image generation
sources. This allows us to generate thumbnails in a more efficient manner.
* Stored files stay as stored files and are not temporarily re-written to
disk;
* Strings containing an image remain as a variable and are not temporarily
written to disk; and
* Arbitrary files are not captured to string.
A new packer for .tar.gz files (MIME type application/x-gzip) has been
implemented, including unit tests.
This packer is intended for use during backup/restore only and is not
otherwise exposed in the user interface at present. However, it is
supposed to follow the (ancient) POSIX .tar standard; files created
with this packer will open in GNU tar.
There are restrictions in support corresponding to the POSIX standard:
- Non-ASCII filenames are not supported.
- Very long file/path names are not supported.
- Individual files within the .tar may not be more than 8GB.
Some of these limitations might need to be addressed in future changes
if the packer were to be used in areas other than backup/restore.
Too many functions, too different parameters, unnecessary DB queries.
All repositories developed for Moodle 2.3-2.5 will continue to work.
Also get rid of DB field files_reference.lifetime, it is not used by
anybody except repository itself.
Fields files.referencelastsync and files.referencelifetime just waste the space and actually duplicate the fields
files_reference.lifetime and files_reference.lastsync
The PHP readfile function does not work for files more than 2GB.
This commit provides a wrapper that can be used so that files less
than 2GB are sent with readfile, and files larger than 2GB are
sent manually.
The change applies to all uses of pluginfile.php, although in
reality, backup files are probably the only ones likely to be more
than two gigabytes.
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);
- 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
- 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)
1. Added tracker issue number in comment
2. Fixed stored_file::delete_reference()
3. repository::send_file() will throw exception if not implemented by subclass
4. Fixed renaming unit test, added one unit test for deleting original file
5. Fixed copyright statement for googledoc and picasa repository plugin
6. Implemented stored_file::set_filesize()
1. Allowing "." as filename, so filemanager can rename folder
2. Fixed import_external_file method
3. Disallow recent repository to list file references
- added new functions to the backend (repository/draftfiles_ajax.php) to allow changing of file name, location, license and author in one request
- enabled changing file properties using JS UI (lib/form/filemanager.js)
