Lots of files which use the Partition class relied on the declaration
being included via other header files. This is bad practice.
Add #include "Partition.h" into every file which uses the Partition
class which doesn't already include it. Header file #include guards are
specifically to allow this.
GParted waits forever when attempting to set a FAT16/32 file system
label which contains prohibited characters [1][2]. This is because
mlabel asks a question and is waiting for input. Force cancelling the
operation doesn't work either as GParted sends signal 2 (interrupt i.e.
[Ctrl-C]) but mtools commands specifically ignores this and a number of
other signals. Have to kill mlabel with signal 9 (kill) to regain
control of GParted.
Mlabel command with prohibited characters in the label:
# export MTOOLS_SKIP_CHECK=1
# mlabel ::"MYLABEL/ " -i /dev/sdb10
Long file name "MYLABEL/ " contains illegal character(s).

Remove prohibited characters from FAT16/32 file systems labels when
creating and labelling them. Also upper case the label to meet label
requirements [1][2]. This silently corrects the label and the actual
label applied will be displayed when GParted refreshes after applying
the operation.

Bug 755608 - Labeling fat16/fat32 partitions hangs if certain characters

The function never modifies any member variables so make it a const
member function.
(FileSystem::get_custom_text() is a virtual function so can't be made
static).

Bug #721565 - License text contains obsolete FSF postal address
Dosfstools >= 3.0.18, released June 2013, renamed the programs thus:
dosfslabel becomes fatlabel,
dosfsck becomes fsck.fat,
and mkdosfs becomes mkfs.fat.
Dosfstools creates symbolic links for the old names for backward
compatibility, but unfortunately the Debian dosfstools-3.0.22-1
(experimental) package doesn't include those symbolic links. This
causes create, check and read unmounted FAT16/32 file systems to not be
supported.
Make GParted look for the new names first and the old names second.
Closes Bug #704629 - Program name changes in dosfstools 3.0.18+ break
FAT16/32 support
Include guards need to be unique within GParted code and all included
library header files.
http://en.wikipedia.org/wiki/Include_guard#Difficulties
Use this model for all include guards:
#ifndef GPARTED_FILE_NAME_H
#define GPARTED_FILE_NAME_H
...
#endif /* GPARTED_FILE_NAME_H */
Closes Bug #539297 - Make include guards unique
Mlabel sometimes writes uninitialised memory at the end of the label.
This causes mlabel, and therefore GParted, to display extra junk at the
end of the label. Depending on the bytes written GParted may also show
the following error on stdout:
(gpartedbin:18116): glibmm-CRITICAL **:
unhandled exception (type Glib::Error) in signal handler:
domain: g_convert_error
code : 1
what : Invalid byte sequence in conversion input
This is caused by a bug in mlabel, believed fixed in mtools 4.0.14.
Effects at least Fedora 14, RHEL/CentOS 6.x and Debian 6. (Use label
"1234567890" on Debian 6 to reproduce). Reproduction steps:
# mkdosfs -F16 /dev/sda7
mkdosfs 3.0.9 (31 Jan 2010)
# export MTOOLS_SKIP_CHECK=1
# mlabel ::123456 -i /dev/sda7
# mlabel -s :: -i /dev/sda7
Volume label is 123456~1t
It is not possible to detect which characters are junk so they can't be
trimmed. Instead just space pad labels so that at least newly written
labels aren't effected. (Fat labels are space padded on the disk by
definition anyway).
Bug #700228 - FAT16/32 labels are sometimes shown corrupted
There was virtually no difference between the separate modules for fat16
and fat32. Remove module fat32 and patch fat16 to serve both file
system subtypes. This is equivalent to what was previously done for
ext[234] by commit:
38dc55d49c
Combine duplicate code for ext[234]
Many filesystems do not implement some of their methods, but had to provide
dummy implementations. Remove all of the dummy implementations and instead
just provide one in the base FileSystem class.
This commit only adds a remove() method to every file system and an
optional call to it in the relevant operations. All remove() methods
are no operations and not enabled.
The remove() method provides explicit controlled removal of a file
system before the partition is deleted or overwritten by being formatted
or pasted into. When implemented, it appears as an extra step in the
relevant operation. The file system specific remove() method is
explicitly allowed to fail and stop the operations currently being
applied.
This is different to the existing erase_filesystem_signatures() which
wipes any previous file system signatures immediately before a new file
system is written to ensure there is no possibility of the partition
containing two or more different file system signatures. It never fails
or reports anything to the user.
NOTE:
Most file systems should NOT implement a remove() method as it will
prevent recovery from accidental partition deletion.
Bug #670171 - Add LVM PV read-write support
Add the ability to set a new random UUID on file systems that provide
the appropriate tools to perform this action.
Update the help manual to include this new functionality. Also add
reference links to "setting a partition label" and "changing a
partition UUID" in the "copying and pasting a partition" section.
This patch does not include setting the UUID on an NTFS file system.
Bug #667278 - Add support for setting UUID
Bug #608308 - fix documentation - Copying and Pasting a Partition
Restore copyright entries by original author to those of his last
known repository commit titled "released gparted-0.3.4 on
LarryT's request." on Feb 25, 2007.
Add my own copyright entries for files in which I changed source
code. Files in which I only made spelling changes do not have my
copyright entry added.
* added support for reading volumelabels. Atm we only read ext2/3, but
the infrastructure for adding the other filesystems is in place.
It's simply a matter of finding the right commands and parsing the
output. (see #338528 for more info)
* added detailed progressfeedback. It still needs some polishing, but
is already far better then the old situation. And what's more, it's
finally threadsafe :p
* The Filesystemclasses: Changed 'bool Create( const Glib::ustring & device_path, const Partition & new_partition )'
to 'bool Create( const Partition & new_partition )'. Since i now use external tools for all filesystems, the partitionpath will suffice.
* Again way too many chances to create a detailed entry (i'm glad i'm the only dev atm :P ).
Resizing of ext2/3 works perfect now. I've even tested it on the partition holding my SG seasons =)
Implemented checking of filesystems (only internally used atm).
Done some overall tweaking, finetuning etc.. release 0.0.7 is getting shape.
* Rewrote a large part of gparteds internal code. Filesystemssupport is now much more separated from the rest of gparted and
adding support for other filesystems should be a piece of cake now (hope that's true :P)
It still needs a lot of love, but the foundations are laid =)
