14 years agoRefactor how we open pack files to prepare for multiple windows.

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
is to have multiple mmap regions active against the same pack file,
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
per packfile, thereby emulating the prior behavior of mmap'ing the
entire pack file.

Introduce new config option for mmap limit.

Rather than hardcoding the maximum number of bytes which can be
mmapped from pack files we should make this value configurable,
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

Replace unpack_entry_gently with unpack_entry.

The unpack_entry_gently function currently has only two callers:
the delta base resolution in sha1_file.c and the main loop of

directly when we implement sliding window mmap logic, so I'm doing
it earlier to help break down the change set.

This may cause a slight performance decrease for delta base
resolution as well as for pack-check.c's verify_packfile(), as
the pack use counter will be incremented and decremented for every

gitweb: Precompile CGI routines for mod_perl

Following advice from CGI(3pm) man page, precompile all CGI routines
for mod_perl, in the BEGIN block.

  If you want to compile without importing use the compile() method

    use CGI();
    CGI->compile();

  This is particularly useful in a mod_perl environment, in which you

git-add: add ignored files when asked explicitly.

One thing many people found confusing about git-add was that a
file whose name matches an ignored pattern could not be added to
the index.  With this, such a file can be added by explicitly
spelling its name to git-add.

Fileglobs and recursive behaviour do not add ignored files to
the index.  That is, if a pattern '*.o' is in .gitignore, and
two files foo.o, bar/baz.o are in the working tree:

    $ git add foo.o
    $ git add '*.o'
    $ git add bar

Only the first form adds foo.o to the index.

14 years agogit-rm: update to saner semantics
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>.

This updates the return value from match_pathspec() so that the
caller can tell cases between exact match, leading pathname
match (i.e. file "foo/bar" matches a pathspec "foo"), or
filename glob match.  This can be used to prevent "rm dir" from
removing "dir/file" without explicitly asking for recursive
behaviour with -r flag, for example.
