Valgrind:
* binparser.c (bin_parser_free): Add this function
* elfparser.c (elf_parser_free): Call bin_parser_free()
* sysprof.c (compute_text_width, add_text): Plug leaks
* collector.c (add_trace_to_stash): Copy n_addresses to a stack
variable instead of reading it out of the mmap'ed area all the
time. (That way if there is an overrun, we won't write too much
into the address array).
2006-10-26 Soren Sandmann <sandmann@daimi.au.dk>
* module/sysprof-module.h (struct SysprofStackTrace): Increase the
max number of addresses to 1021, reorganise SysprofMmapArea to
make the traces naturally page aligned.

Communicate traces to userspace through shared memory instead of
copying.
* module/sysprof-module.c: Store the traces in a SysprofMmapArea.
(sysprof_mmap): Implement this method.
(sysprof_nopage): Implement this.
(sysprof_read): Just reset the tail pointer and return zero.
* module/sysprof-module.h (struct SysprofMmapArea): New
structure.
* collector.c (collector_stop): Unmap the device
(in_dead_period): New function
(on_read): Read the traces out of mmap()ed area instead of reading
them. Call read() to prevent poll() from firing.
(struct Collector): New members map_area and current.
* Makefile.am (insert-module): Prefix modprobe with /sbin
* collector.c (open_fd): mmap() the sysprof device.
2006-10-09 Soren Sandmann <sandmann@daimi.au.dk>

list of immediate callers again.
* sysprof.c (build_gui): Change label back to "Callers"
* process.c (get_kernel_symbols): Only attempt to read the kernel
symbols once.
2006-10-09 Soren Sandmann <ssp@localhost.localdomain>
* process.c (process_get_vdso_bytes): New function.
* elfparser.c (parser_new_from_data): export this function as
elf_parser_new_from_data().
* binfile.c (read_inode): Don't stat if filename is
'[vdso]'. Instead just return -1;
(bin_file_new): Use elf_parser_new_from_data() when the file is
[vdso].
* process.c (read_maps): Change the offset of the vdso map to 0
and the inode to -1.
* elfparser.c (elf_parser_lookup_symbol): Remove unused 'size'
variable.

* elfparser.c (struct ElfParser): Add a cache of the text section.
* binparser.c (struct BinParser): Add a cache of a bin record to
get rid of malloc()/free() overhead.
* elfparser.c (struct ElfSym): Cache the size of the symbol
2006-10-08 Soren Sandmann <sandmann@daimi.au.dk>
* binfile.c (find_separate_debug_file): Support _debuglink
recursions.
* elfparser.c: Check that the sections have valid types before
using them.
2006-10-07 Soren Sandmann <sandmann@daimi.au.dk>
Deal with address offsets. Address lookup is now:
- First convert the address to an offset into the file
- Then convert to an offset into the text segment
- Then add the load address of the text segment (found in the
debug binary)
- Then finally lookup the result in the symbol table.
* elfparser.c (elf_parser_get_text_offset): New function
* elfparser.c (elf_parser_lookup_symbol): Treat addresses as
offsets into the text segment.
* binfile.c (bin_file_new): Store the offset of the text section
of the actual binary (not the debug one)
(bin_file_lookup_symbol): Subtract text_offset before passing
address to elf parser.
* module/sysprof-module.c: Remove include of linux/config.h
