    [PATCH] fetch.c: Remove call to parse_object() from process()

    sigprof authored Junio C Hamano committed
    The call to parse_object() in process() is not actually needed - if
    the object type is unknown, parse_object() will be called by loop();
    if the type is known, the object will be parsed by the appropriate
    process_*() function.
    
    After this change blobs which exist locally are no longer parsed,
    which gives about 2x CPU usage improvement; the downside is that there
    will be no warnings for existing corrupted blobs, but detecting such
    corruption is the job of git-fsck-objects, not the fetch programs.
    Newly fetched objects are still checked for corruption in http-fetch.c
    and ssh-fetch.c (local-fetch.c does not seem to do it, but the removed
    parse_object() call would not be reached for new objects anyway).

    [PATCH] fetch.c: Remove redundant test of TO_SCAN in process()

    sigprof authored Junio C Hamano committed
    If the SEEN flag was not set, the TO_SCAN flag cannot be set,
    therefore testing it is pointless.

    [PATCH] fetch.c: Remove some duplicated code in process()

    sigprof authored Junio C Hamano committed
    It does not matter if we call prefetch() or set the TO_SCAN flag before
    or after adding the object to process_queue.  However, doing it before
    object_list_insert() allows us to kill 3 lines of duplicated code.

    [PATCH] fetch.c: Remove redundant TO_FETCH flag

    sigprof authored Junio C Hamano committed
    The TO_FETCH flag also became redundant after adding the SEEN flag -
    it was set and checked in process() to prevent adding the same object
    to process_queue multiple times, but now SEEN guards against this.

    [PATCH] fetch.c: Remove redundant SCANNED flag

    sigprof authored Junio C Hamano committed
    After adding the SEEN flag, the SCANNED flag became obviously
    redundant - each object can get into process_queue through process()
    only once, and therefore multiple calls to process_object() for the
    same object are not possible.

    [PATCH] fetch.c: Make process() look at each object only once

    sigprof authored Junio C Hamano committed
    The process() function is very often called multiple times for the
    same object (because lots of trees refer to the same blobs), but did
    not have a fast check for this, therefore a lot of useless calls to
    has_sha1_file() and parse_object() were made before discovering that
    nothing needs to be done.
    
    This patch adds the SEEN flag which is used in process() to make it
    look at each object only once.  When testing git-local-fetch on the
    repository of GIT, this gives a 14x improvement in CPU usage (mainly
    because the redundant calls to parse_object() are now avoided -
    parse_object() always unpacks and parses the object data, even if it
    was already parsed before).

    [PATCH] fetch.c: Remove useless lookup_object_type() call in process()

    sigprof authored Junio C Hamano committed
    In all places where process() is called except the one in pull() (which
    is executed only once) the pointer to the object is already available,
    so pass it as the argument to process() instead of sha1 and avoid an
    unneeded call to lookup_object_type().

  11. Do not give alarming error message from rsync in fetch and clone.

    Junio C Hamano authored
    When we check the optional objects/info/alternates file at the remote
    repository, we forgot to really squelch error message from rsync.

  1. Fix documentation dependency.

    Junio C Hamano authored
    Randal L. Schwartz noticed that 'make install' does not rebuild what
    is installed.  Make the 'install' rule depend on 'man'.
    
    I noticed also 'touch' of the source files were used to express include
    dependencies, which is a no-no.  Rewrite it to do dependencies properly,
    and add missing include dependencies while we are at it.

  2. Make object creation in http fetch a bit safer.

    Junio C Hamano authored
    Unlike write_sha1_file() that tries to create the object file in a
    temporary location and then move it to the final location, fetch_object
    could have been interrupted in the middle, leaving a corrupt file.

    get_sha1() would not do sha1 completion of short SHA1's when they were

  4. [PATCH] Improved "git add"

    Linus Torvalds authored Junio C Hamano committed
    This fixes everybodys favourite complaint about "git add", namely that it
    doesn't take directories.
    
    We use "git-ls-files --others" to generate an arbitrary list of filenames,
    and thus also automatically honor ignore-files while we're at it.
    
    Side note: there's a lot of room for improvement here. In particular, if
    we have a long list of filenames (importing a big archive), this will just
    do a big stupid for-loop and add them one at a time. Maybe it should use
    
    	generate-list | xargs -0 git-update-idex --add --
    
    instead.
    
    Also, I think we should have a default ignore list if we don't find a
    .git/info/exclude file. Ignoring "*.o" and ".*" by default would probably
    be the right thing to do.
    
    But I think this is a good first step.
    
    Use the "-n" flag to just show the list of files to be added without
    adding them.

    So add a flag to git-rev-parse to show where it is, since it will have
    figured it out anyway.

  10. Improve the safety check used in fetch.c

    Junio C Hamano authored
    The recent safety check to trust only the commits we have made
    things impossibly slow and turn out to waste a lot of memory.
    
    This commit fixes it with the following improvements:
    
     - mark already scanned objects and avoid rescanning the same
       object again;
    
     - free the tree entries when we have scanned the tree entries;
       this is the same as b0d8923
       which reduced memory usage by rev-list;
    
     - plug memory leak from the object_list dequeuing code;
    
     - use the process_queue not just for fetching but for scanning,
       to make things tail recursive to avoid deep recursion; the
       deep recursion was especially prominent when we cloned a big
       pack.
    
     - avoid has_sha1_file() call when we already know we do not have
       that object.
