mmap is not the territory Part 1 : http://techtalkies.blogspot.com/2010/09/mmap-is-not-territory-or-mapfail-sigbus.html

mmap() is not the territory!! Part 1

(OR) how MAP_FAIL, SIGBUS,

beg to differ with mmap!!
Wrote a small program using mmap() to copy a fromFile.txt to toFile.txt using virtual memory

--------------------------------------------
Issue#1: mmap() returns MAP_FAIL
mmap() requires exactly the same flags as the filedescriptor/fd as when it was open()/creat()-ed
i.e. if you used O_RDONLY in open() then you can't mmap() it as PROT_WRITE.

chmod basics: http://www.linux.org/lessons/beginner/l14/lesson14b.html
creat/open man page: http://linux.about.com/od/commands/l/blcmdl2_open.htm
-------------------------------------------------
Issue#2:
Error Message: In gdb getting SIGBUS with error coming from inside memcpy!!

108        memcpy(destFilePtr, srcFilePtr, pageSize);
5: pageSize = 14
4: destFilePtr = 0xb7ffc000

3: srcFilePtr = 0xb7ffd000 "hello, world\n\n"
2: destfd = 6
1: srcfd = 5
(gdb) n

Program received signal SIGBUS, Bus error.
__memcpy_ia32 () at ../sysdeps/i386/i686/multiarch/../memcpy.S:75
75    ../sysdeps/i386/i686/multiarch/../memcpy.S: No such file or directory.
    in ../sysdeps/i386/i686/multiarch/../memcpy.S

 

Searching on this gave no direct answers on the error message but gave some pointers on causes.

Tried all the below tools but still getting the same error message:

0) used apt-get update and rebooted "just-in-case"

    https://help.ubuntu.com/8.04/serverguide/C/apt-get.html

1) used strace ./file-copy-vm to check the system calls were getting called properly.

   getting SIGBUS on write() ostensibly called from inside the memcpy

2) used ldd ./file-copy-vm to check that the libstdc++ - and libc.so were existent.

   They were present

3) Installed glibc-dbg and libstdc++-devel etc for debugging the library.

    No change.

Finally found the problem in an off-by-N error in memcpy(dest,src, pageSize)

Since SIGBUS comes when a page worth is allocated but size of mapping is less than pagesize. 

i.e. the accessed address is more than filesize but inside pagesize.

 So realized my mistake and changed:

        memcpy(destFilePtr, srcFilePtr, pageSize); //WRONG.

Corrected it to:

        memcpy(destFilePtr, srcFilePtr, sb.st_size); //Correct

------------------------------------------------------------------------------------------------------------------

Hmmm... here the destFilePtr seems to be pointing to the correct memory-mapped file i.e. toFile.txtThe destFilePtr

is pointing to out-of-bounds accesss.

Also the SIGBUG seems to suggest that I'm trying to write/access to an address in memory that's allocated but out of bounds of the empty dest file. Otherwise I'd have got a SIGSEGV if the memory had not been allocated.

 

I observed that toFile.txt is showing filesize as zero on the disk. Aha!!

 

Robert Love in his book "Linux System Programming" had mentioned files with slack-space/holes (in memory as well as disk respectively). Could this be the reason??!! 

http://www.devshed.com/c/a/BrainDump/Using-mmap-for-Advanced-File-IO/

Finally I cross-checked my code with a sample implementation for mmap() file copy program.

Found out that they used lseek() to expand the memory mapping instead of ftruncate() to expand file size with a hole instead of ftruncate().

http://www.c.happycodings.com/Gnu-Linux/code6.html

So we just need to increase the size of the dest-file using ftruncate.

(gdb) help call
Call a function in the program.
The argument is the function name and arguments, in the notation of the
current working language.  The result is printed and saved in the value
history, if it is not void.

(gdb) call ftruncate(destfd,sb.st_size)
$1 = 0

doFileCopyWithSharedMem() returned:0
system(diff ./fromFile.txt ./toFile.txt) returned: 0
testFileCopyWithSharedMem() returned:0

(gdb)

Hurray!! the unit testcase passes!! 
It's 6 AM!! Tiring but worth it!! Gotta go and sleep now

Utils for Linux and Windows

Search Everything:
This is a really fast and compact file search utility for windows. It beats Google desktop hollow if all you need is to search file/directory names. Already its saved me from re-downloading stuff, finding work that I’d stored away (safely!!) somewhere and just plain discover that I’ve got more goodies on my system than I’d thought!!
Having a huge HDD (by today’s standards) 1 GB does help to keep useful stuff ready for “Search Everything”.
Some nifty features to add would have been
1) Search inside compressed files and maybe
2) Catalog generation for offline media like CDs/DVDs.

Bharat has written a nice blog post on it called "Search Everything – A wonderful utility to reduce file searches".

Recently reinstalled Windows/Ubuntu and had to reinstall all the stuff.

I was using the old blog editor in blogger and managed to lose nearly 75% of a blog.
No undo function to revert to previous version of my blog. Searched for a work-around in blogger.
Nearly 3 hours of hard-work gone down the drain.
Found these GUI utilities for Ubuntu and Windows to hold ALL copy-paste stuff from the clipboard.

1) Glipper the multiple copies clipboard manager on Ubuntu Gnome Desktop

#a) Installs Glipper the multiple copies clipboard manager into Ubuntu Gnome Desktop
apt-get install glipper
#b) Right click on the "Windows Quicklaunch Bar" and Add to Panel->Clipboard manager
#c) Click on any of the previous copies to get the copy-paste you need.

2) Nautilus elementary -> Elegant Gnome. Making the desktop look neat.
     http://gnome-look.org/content/show.php/Elegant+Gnome+Pack?content=127826
     (Found it from somewhere inside http://lifehacker.com/tag/linux/!!)

3) Also Clipboard Manager for Windows for extending the basic Windows clipboard.
      http://space.dl.sourceforge.net/project/clipman/Clipman/v1.0/ClipMan_Setup.msi
      Note: May require .net framework 2.0.50727 to run if it's not already installed.

Under The Hood Look At Operating Systems Internals with Windows and Linux

[08-Sep-2010]

Extremely Recommended reading:

• Checkout this Blog on Operating Systems (Linux And Windows) by Gustavo Duartes http://duartes.org/gustavo/blog/

• This blog has some simply delicious diagrams with 1-2 page explanations of Paging, Virtual Memory, Caching, Physical level RAM, Snapshot of a Process in Memory.
  
• This is a simply superb blog. "A picture is worth a thousand words!!". The articles have some high quality illustrations which esp. for visual learners is a delight. Just working through the flow in the diagrams makes the text just an add-on (to explicitly elaborate on any point you might have missed).
  
• This helps you get an "all-at-once" picture of the entire flow and inter-relationships between different parts (esp. if you're a visual/top-down learner).
• I learned more in 30 minutes of analyzing these lovely diagrams than boring holes in all the below books for days on end.

Once you've gone through this blog the below books become so much more intelligible:

• Operating System Concepts 5th ed. by Galvin et. al.
• Understanding the Linux Kernel 3rd ed. by Bovet and Cesati
• Linux System Programming by Robert Love

Good article on RSS and VSZ reporting by ps aux and pmap to determine memory footprint of your proces. 
See the comments for some good discussion of internals
