Loop over pack_windows when inflating/accessing data.

When multiple mmaps start getting used for all pack file access it
is not possible to get all data associated with a specific object
in one contiguous memory region.  This limitation prevents simply
passing a single address and length to SHA1_Update or to inflate.

Instead we need to loop until we have processed all data of interest.

As we loop over the data we are always interested in reusing the same
window 'cursor', as the prior window will no longer be of any use
to us.  This allows the use_pack() call to automatically decrement
the use count of the prior window before setting up access for us
to the next window.

Within each loop we need to make use of the available length output
parameter of use_pack() to tell us how many bytes are available in
the current memory region, as we cannot tell otherwise.

17 years agoReplace use_packed_git with window cursors.
Shawn O. Pearce [Sat, 23 Dec 2006 07:34:08 +0000 (02:34 -0500)]
Replace use_packed_git with window cursors.

Part of the implementation concept of the sliding mmap window for
pack access is to permit multiple windows per pack to be mapped
independently.  Since the inuse_cnt is associated with the mmap and
not with the file, this value is in struct pack_window and needs to
be incremented/decremented for each pack_window accessed by any code.

To faciliate that implementation we need to replace all uses of
use_packed_git() and unuse_packed_git() with a different API that
follows struct pack_window objects rather than struct packed_git.

The way this works is when we need to start accessing a pack for
the first time we should setup a new window 'cursor' by declaring
a local and setting it to NULL:

  struct pack_windows *w_curs = NULL;

To obtain the memory region which contains a specific section of
the pack file we invoke use_pack(), supplying the address of our
current window cursor:

  unsigned int len;
  unsigned char *addr = use_pack(p, &w_curs, offset, &len);

the returned address `addr` will be the first byte at `offset`
within the pack file.  The optional variable len will also be
updated with the number of bytes remaining following the address.

Multiple calls to use_pack() with the same window cursor will
update the window cursor, moving it from one window to another
when necessary.  In this way each window cursor variable maintains
only one struct pack_window inuse at a time.

Finally before exiting the scope which originally declared the window
cursor we must invoke unuse_pack() to unuse the current window (which
may be different from the one that was first obtained from use_pack):

  unuse_pack(&w_curs);

This implementation is still not complete with regards to multiple
windows, as only one window per pack file is supported right now.

Refactor how we open pack files to prepare for multiple windows.

To efficiently support mmaping of multiple regions of the same pack
file we want to keep the pack's file descriptor open while we are
actively working with that pack.  So we are now keeping that file
descriptor in packed_git.pack_fd and closing it only after we unmap
the last window.

This is going to increase the number of file descriptors that are
in use at once, however that will be bounded by the total number of
pack files present and therefore should not be very high.  It is
a small tradeoff which we may need to revisit after some testing
can be done on various repositories and systems.

For code clarity we also want to seperate out the implementation
of how we open a pack file from the implementation which locates
a suitable window (or makes a new one) from the given pack file.
Since this is a rather large delta I'm taking advantage of doing
it now, in a fairly isolated change.

When we open a pack file we need to examine the header and trailer
without having a mmap in place, as we may only need to mmap
the middle section of this particular pack.  Consequently the
verification code has been refactored to make use of the new
read_or_die function.

Refactor packed_git to prepare for sliding mmap windows.

The idea behind the sliding mmap window pack reader implementation

thereby allowing the process to mmap in only the active/hot sections
of the pack and reduce overall virtual address space usage.

To implement this we need to refactor the mmap related data
(pack_base, pack_use_cnt) out of struct packed_git and move them
into a new struct pack_window.

We are refactoring the code to support a single struct pack_window

Introduce new config option for mmap limit.

Rather than hardcoding the maximum number of bytes which can be

allowing the end user to increase or decrease this limit on a
per-repository basis depending on the size of the repository
and the capabilities of their operating system.

In general users should not need to manually tune such a low-level
setting within the core code, but being able to artifically limit
the number of bytes which we can mmap at once from pack files will

Junio C Hamano [Mon, 25 Dec 2006 11:11:00 +0000 (03:11 -0800)]
git-rm: update to saner semantics

This updates the "git rm" command with saner semantics suggested
on the list earlier with:

Message-ID: <Pine.LNX.4.64.0612020919400.3476@woody.osdl.org>
Message-ID: <Pine.LNX.4.64.0612040737120.3476@woody.osdl.org>

The command still validates that the given paths all talk about
sensible paths to avoid mistakes (e.g. "git rm fiel" when file
"fiel" does not exist would error out -- user meant to remove
"file"), and it has further safety checks described next.  The
biggest difference is that the paths are removed from both index
and from the working tree (if you have an exotic need to remove
paths only from the index, you can use the --cached option).

The command refuses to remove if the copy on the working tree
does not match the index, or if the index and the HEAD does not
match.  You can defeat this check with -f option.

This safety check has two exceptions: if the working tree file
does not exist to begin with, that technically does not match
the index but it is allowed.  This is to allow this CVS style
command sequence:

rm <path> && git rm <path>

Also if the index is unmerged at the <path>, you can use "git rm
<path>" to declare that the result of the merge loses that path,
and the above safety check does not trigger; requiring the file
to match the index in this case forces the user to do "git
update-index file && git rm file", which is just crazy.

To recursively remove all contents from a directory, you need to
pass -r option, not just the directory name as the <path>.
