This patch adds a new performance metric to the performance
info shown by MDL_PERF* vars, the time spent by the database,
it was one of the wonderful @poltawski ideas. To be more specific
the value displayed is the sum of the time elapsed between query_start()
and query_end().
1/ always require 3 behat settings - $CFG->behat_wwwroot, $CFG->behat_dataroot and $CFG->behat_prefix
2/ cleanup init code
3/ do not require $CFG->wwwroot and $CFG->dataroot on test sites
4/ remove switch completely - the most confusing part for me
5/ print out behat_wwwwroot in init script so that you can test the test site manually
The new experimental setting enabletgzbackups allows backups to be
created so that the internal format for .mbz files is .tar.gz.
Restore transparently supports .mbz files with either internal
formats (.zip or .tar.gz).
The .tar.gz format has the following benefits for backup:
- Supports larger files (no limit on total size, 8GB on single file
vs. 4GB limit on total size)
- Compresses text better, resulting in smaller .mbz files.
- Reports progress regularly during compression of single files,
reducing the chance of timeouts during backups that include a
very large file.
Time performance may also be improved although I haven't done a
direct comparison.
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.
