PipeCapture::OnReadable() has been almost completely re-written but this
test is still failing thus:
$ ./test_PipeCapture
...
[ RUN ] PipeCaptureTest.MinimalBinaryCrash777973
test_PipeCapture.cc:313: Failure

...
The OnReadable() code specifically skips invalid bytes which aren't part
of valid UTF-8 characters, because they can't be displayed to the user.
The final C2 byte is the start of a multi-byte UTF-8 character, so on
it's own is invalid. Therefore PipeCapture skips it. Update expected
string accordingly. Now the test passes.
Bug 777973 - Segmentation fault on bad disk
A user had a very corrupted FAT file system such that fsck.fat produced
122 MiB of output. GParted has to read this output to get the file
system usage information. However GParted takes more than 48 hours to
read the 122 MiB of output, while using 100% CPU time and is
unresponsive for the duration.
Modified fsck.fat to output just the first 1 MiB of output and used perf
to capture performance data from GParted reading that output:
# perf -g -F 1999 -- ./gpartedbin
# perf report --stdio
67.84% Glib::ustring::replace [4.23s]
17.67% g_utf8_pointer_to_offset [1.10s]
8.48% g_utf8_offset_to_pointer [0.53s]
[ 6.01% (everything else) ] [0.38s]
[100.00% TOTAL ] [6.24s]
And to read the first 10 MiB of output the performance figures are:
92.95% Glib::ustring::replace [257.44s]
4.35% g_utf8_pointer_to_offset [ 12.05s]
2.13% g_utf8_offset_to_pointer [ 5.90s]
[ 0.58% (everything else) ] [ 1.61s]
[100.00% TOTAL ] [277.00s]
See how the total time is increasing non-linearly, 44 times longer for
only 10 times as much data. This is because of the exponential increase
in time spent in Glib::ustring::replace.
After a lot of experimentation I came to the conclusion that
Glib::ustrings are not appropriate for storing and editing large buffers
of data, sizes megabytes and above. The issues are that iterators are
invalid after the content changes and replacing UTF-8 characters by
index gets exponentially slower as the size of the string increases.
Hence the > 48 hours of 100% CPU time to read and apply the line
discipline to the 122 MiB of fsck.fat output. See code comment for a
more detailed description of the issues found.
Rewrote OnReadable() to use Glib::ustrings as little as possible.
Instead using buffers and vectors of fixed width data types allowing for
fast access using pointers and indexes (converted to pointers by the
compiler with simple arithmetic). Again see code comment for a more
detailed description of the implementation.
Repeating the performance capture with the new code for the first 1 MiB
of fsck.fat output:
63.34% memcpy [0.35s]
[ 36.66% (everything else) ] [0.21s]
[100.00% TOTAL ] [0.56s]
And for the first 10 MiB of fsck.fat output:
96.66% memcpy [63.60s]
[ 3.34% (everything else) ] [ 2.20s]
[100.00% TOTAL ] [65.80s]
Simple timings taken to read portions of the fsck.fat output (when not
using perf):
1 MiB 10 MiB 122 MiB
old code : 6.2 sec 277 sec > 48 hours
(4:37)
new code : 0.6 sec 66 sec 17262 sec
(1:06) (4:47:42)
Performance of the code is still non-linear because of the assignment
of the ever growing capturebuf to callerbuf for every block of input
read. This is required to generate a consistent Glib::ustring copy of
the input for the update callback. However this is much faster than
before, and I have a plan for further improvements.
Bug 777973 - Segmentation fault on bad disk
Initialise capture string with sacrificial text before each test.
Existing tests confirm this is cleared first by checking the captured
string matches the input string.
Bug 777973 - Segmentation fault on bad disk
Seems more logical to initially clear the output capture buffer in a
single location in the PipeCapture class which reads the command output
into said buffer, rather than each calling site before the PipeCapture
objects are constructed.
Bug 777973 - Segmentation fault on bad disk
A user had a very corrupted FAT file system and when GParted was reading
the file system usage it would core dump. The tip of the stack trace
was:
#0 Glib::ustring_Iterator<__gnu_cxx::__normal_iterator<char*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >::operator++()
at /usr/include/glibmm-2.4/glibmm/ustring.h line 957

#2 GParted::PipeCapture::OnReadable(Glib::IOCondition)
at PipeCapture.cc line 63
#3 GParted::PipeCapture::_OnReadable(_GIOChannel*, GIOCondition, void*)
at PipeCapture.cc line 45
GParted uses 'fsck.fat -n -v /dev/PTN' to get the file system usage.
However because the file system was so corrupted it was reporting every
file name as being damaged, including the file names being reported as
binary data. PipeCapture::OnReadable() reads up to 512 bytes at a time
and then uses a Glib::ustring iterator to loop over the UTF-8
characters, but a Glib::ustring iterator is explicitly not capable of
reading binary data [1]. With invalid UTF-8 bytes the code continued to
read beyond the end of the string until GParted crashed with a
segmentation violation.
Fix by accessing the read string by index instead of by iterator.
[1] Quote from the Glib::ustring_Iterator<T> Class Template Reference:
https://developer.gnome.org/glibmm/stable/classGlib_1_1ustring__Iterator.html
"The Glib::ustring iterated over must contain only valid UTF-8 data.
If it does not, operator++(), operator--() and operator*() may make
accesses outside the bounds of the string."
Bug 777973 - Segmentation fault on bad disk
A user had a very corrupt FAT file system and fsck.fat was reporting
binary data in file names with errors. GParted crashed reading this
output. Boiled down the problematic fsck.fat output to a sample 27
bytes which still triggers a crash and created a test for it. The test
crashes test_PipeCapture program too.

Also ensure that the PipeCapture calls registered update callbacks and
that the data so far captured matches the leading portion of the input.
Bug 777973 - Segmentation fault on bad disk
Google Test string comparison asserts are only designed of C style
strings containing printable text of one or more lines with a
terminating NUL character. GParted is crashing when PipeCapture is
reading the binary file names being reported by fsck.fat from a very
corrupted FAT file system. Therefore need to be able to compare and
report differences of binary data stored in C++ std::string and
Glib::ustrings. Write a specific assertion to handle this.
Now these sample tests:
TEST_F( PipeCaptureTest, BinaryStringFailure )
{
inputstr = "AAAAAAAAAAAAAAAABBBBBBBBBBBBBBBBCCCCCCCCCCCCCCCC";
capturedstr = "AAAAAAAAAAAAAAAABBBBBBBBBBbbbb";
EXPECT_BINARYSTRINGEQ( inputstr, capturedstr.raw() );
}
TEST_F( PipeCaptureTest, LeadingBinaryStringFailure )
{
inputstr = "The quick brown fox jumps over the lazy dog";
capturedstr = "The quick brown fox\n";

Bug 777973 - Segmentation fault on bad disk
Add test sending 1 MiB of ASCII test into PipeCapture to read. This
requires multiple reads and rewites through the pipe.
This is as much a check of the threading in the PipeCaptureTest class as
it is of PipeCapture itself. This is because a single thread might
block reading from a pipe waiting for itself to write to the pipe.
Deadlock. Hence the requirement to use a separate thread for reading
and writing.

As the source code is managed in GIT and there is a .gitignore file in

The Libtool Manual, 5.5.1 Invoking libtoolize

"If libtoolize detects an explicit call to AC_CONFIG_MACRO_DIRS (see
The Autoconf Manual in The Autoconf Manual) in your configure.ac, it
will put the Libtool macros in the specified directory.
In the future other Autotools will automatically check the contents
of AC_CONFIG_MACRO_DIRS, but at the moment it is more portable to
add the macro directory to ACLOCAL_AMFLAGS in Makefile.am, which is
where the tools currently look. If libtoolize doesn't see
AC_CONFIG_MACRO_DIRS, it too will honour the first '-I' argument in
ACLOCAL_AMFLAGS when choosing a directory to store libtool
configuration macros in. It is perfectly sensible to use both
AC_CONFIG_MACRO_DIRS and ACLOCAL_AMFLAGS, as long as they are kept
in synchronisation.

Deliberately breaking one of the operator<() tests produces less than
ideal diagnostics because it doesn't print the BlockSpecial objects
being compared.
$ ./test_BlockSpecial
...
[ RUN ] BlockSpecialTest.OperatorLessThanTwoEmptyObjects
test_BlockSpecial.cc:362: Failure
Value of: bs1 < bs2
Actual: true
Expected: false
[ FAILED ] BlockSpecialTest.OperatorLessThanTwoEmptyObjects (1 ms)
...
This could be solved by using the Google Test Binary Comparison
assertions, however in the tests for false from (bs1 == bs2) and
(bs1 < bs2) comparisons then operators != and >= would have to be
implemented and the tests changed from:
EXPECT_FALSE( bs1 < bs2 );
to:
EXPECT_GE( bs1, bs2 );
This makes the meaning of the test less than clear. The primary purpose
of the test is to check operator<(), but it is expecting the first
BlockSpecial object to be GE (greater than or equal to) than the second,
which is calling operator>=() which in turn is testing operator<(). For
tests of the operators themselves using Google Test Binary Comparison
assertions obscures what is being tested too much.
Instead provide a custom failure message which prints the BlockSpecial
objects failing the comparison, leaving the test still directly calling
the operator being tested, like this:
EXPECT_FALSE( bs1 < bs2 ) << " Where: bs1 = " << bs1 << "\n"
<< " And: bs2 = " << bs2;
And with a suitable macro this is simplified to:
EXPECT_FALSE( bs1 < bs2 ) << ON_FAILURE_WHERE( bs1, bs2 );
Now the above deliberately broken test produces this output:
$ ./test_BlockSpecial
...
[ RUN ] BlockSpecialTest.OperatorLessThanTwoEmptyObjects
test_BlockSpecial.cc:369: Failure
Value of: bs1 < bs2
Actual: true

make: *** [distcheck] Error 1
What is happening is that distcheck [1] performs a VPATH build which
uses separate read-only source and read-write build trees. Shipped
source files, such as .h and .cc, are located in the source tree and the
built files, such as .o and .la, are compiled into the build tree. In
this case the absolute path to libgtest_main.la is specified using
$(top_srcdir) for the source tree, rather than $(top_builddir) for the
build tree, hence the cannot find file type error. This error doesn't
occur when just performing a 'make check' because that builds in the
source tree so $(top_builddir) is the same as $(top_srcdir).
Fix by correctly specifying the absolute path to the libgtest*.la files
using $(top_builddir).
[1] Automake Manual, 14.4 Checking the Distribution
https://www.gnu.org/software/automake/manual/automake.html#Checking-the-Distribution
Note that for VPATH builds the Automake Manual [2] also recommends using
a pair of -I options to specify header files are found in both the build
and source trees, something like:
AM_CPPFLAGS = -I$(top_builddir)/some/subdir -I$(top_srcdir)/some/subdir
This is unnecessary for GParted as all header files are shipped as part
of the source archive and no header files are created as part of the
build process. Therefore adding -I options specifying $(top_builddir)
include directories would just be specifying empty or non-existent
include directories in the build tree.

consistent with how it is done in all the online file system resizing
code.
Bug 782681 - btrfs partitions mounted with whitespace cannot be resized
The current nilfs2 resizing code is safe because it never passes a user

simple rule to always quote mount points when used in command lines.
WARNING:
Nilfs-resize is broken and can't actually resize a file system mounted

Bug 782681 - btrfs partitions mounted with whitespace cannot be resized
A user had a btrfs file system mounted by automounter on a mount point
like "/mount/$USER/File System Label" which included white space
characters. Resizing the file system while online failed like this:
Grow /dev/sdb1 from 1.00 GiB to 1.50 GiB

btrfs filesystem resize: too many arguments
usage: btrfs filesystem resize [devid:][+/-]<newsize>[kKmMgGtTpPeE]|[devid:]max <path>
So mount points not created by GParted should be considered under user
control and need quoting when used as parameters in command lines.
Strictly speaking, mount points created by GParted itself, by
FileSystem::mk_temp_dir(), are safe and don't need quoting. However it
is simpler and safer just to quote all uses of mount points in command
lines, rather than risk missing some.

Shallow copy Device object into Operation object (#750168)
The commit message claimed that the deep copied Partition objects inside
the Device inside the Operation object are never accessed. This turned
out not to be true. Win_GParted::Add_Operation() uses them as part of
snap_to_alignment() which updates requested partition boundaries to
account for alignment requirements and the space needed for EBR
(Extended Boot Record) preceding logical partitions.
In this case the new logical partition was trying to be created over the
top of the EBR for the following logical partition because
snap_to_alignment() wasn't aware of its existence.
Fix by making Add_Operation() and snap_to_alignment() refer to the
current device, as displayed in the UI, rather than the shallow copy
included in the Operation object. Hopefully now it is true that the
not copied vector of Partition objects in the Device object in each
Operation object are never accessed.

Bug 778628 - Work around automake-1.15 & intltool complaining about
translations in build dir
Increase the size of the Name Partition dialog, matching the change made
to the Label File System dialog in the previous commit. The code for
the Name Partition dialog was basically copied from the Label File
System dialog.
Bug 778003 - The "Label File System" dialog is too small
On Arch Linux with XFCE 4.12 and Fedora 24 with GNOME 3.20 and later;
the Label File System dialog is too small. The problem is that the
label entry box clips the Cancel and OK buttons.
Stop specifying the dialog height, instead letting it fit the combined
height of all the widgets automatically.
Also make the dialog wider and the label entry box wider so that longer
device names can be shown in the title before they are truncated.
