| | | | | | | | | | | | | | | | | | | | | | | | git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

| * | let pack-objects do the writing of unreachable objects as loose objectsNicolas Pitre2008-05-13
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ccc1297226b184c40459e9d373cc9eebfb7bd898 changed the behavior of 'git repack -A' so unreachable objects are stored as loose objects. However it did so in a naive and inn efficient way by making packs about to be deleted inaccessible and feeding their content through 'git unpack-objects'. While this works, there are major flaws with this approach: - It is unacceptably sloooooooooooooow. In the Linux kernel repository with no actual unreachable objects, doing 'git repack -A -d' before: real 2m33.220s user 2m21.675s sys 0m3.510s And with this change: real 0m36.849s user 0m24.365s sys 0m1.950s For reference, here's the timing for 'git repack -a -d': real 0m35.816s user 0m22.571s sys 0m2.011s This is explained by the fact that 'git unpack-objects' was used to unpack _every_ objects even if (almost) 100% of them were thrown away. - There is a black out period. Between the removal of the .idx file for the redundant pack and the completion of its unpacking, the unreachable objects become completely unaccessible. This is not a big issue as we're talking about unreachable objects, but some consistency is always good. - There is no way to easily set a sensible mtime for the newly created unreachable loose objects. So, while having a command called "pack-objects" to perform object unpacking looks really odd, this is probably the best compromize to be able to solve the above issues in an efficient way.

* | pack-objects: allow for early delta deflatingNicolas Pitre2008-05-03

This last point is especially relevant for SMP run time. For example, repacking the Linux repo on a quad core processor using 4 threads with all default settings produce the following results before this change: real 2m27.929s user 4m36.492s sys 0m3.091s And with this change applied: real 2m13.787s user 4m37.486s sys 0m3.159s So the actual execution time stayed more or less the same but the wall clock time is shorter. This is however not a good thing to do when generating a pack for network transmission. In that case, the network is most likely to throttle the data throughput, so it is best to make find_deltas() faster in order to start writing data ASAP since we can afford spending more time between writes to compress the data at that point.

* pack-objects: proper pack time stamping with --max-pack-sizeNicolas Pitre2008-03-13
| | | | | | | | | | | | Runtime pack access is done in the pack file mtime order since recent packs are more likely to contain frequently used objects than old packs. However the --max-pack-size option can produce multiple packs with mtime in the reversed order as newer objects are always written first. Let's modify mtime of later pack files (when any) so they appear older than preceding ones when a repack creates multiple packs. Signed-off-by: Nicolas Pitre <nico@cam.org>
* git-pack-objects: Automatically pack annotated tags if object was packedShawn O. Pearce2008-03-04
| | | | | | | | | | | | | | | | | | | The new option "--include-tag" allows the caller to request that any annotated tag be included into the packfile if the object the tag references was also included as part of the packfile. This option can be useful on the server side of a native git transport, where the server knows what commits it is including into a packfile to update the client. If new annotated tags have been introduced then we can also include them in the packfile, saving the client from needing to request them through a second connection. This change only introduces the backend option and provides a test. Protocol extensions to make this useful in fetch-pack/upload-pack are still necessary to activate the logic during transport.

E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

* | | pack-objects: Add runtime detection of online CPU'sAndreas Ericsson2008-02-23
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packing objects can be done in parallell nowadays, but it's only done if the config option pack.threads is set to a value above 1. Because of that, the code-path used is often not the most optimal one. This patch adds a routine to detect the number of online CPU's at runtime (online_cpus()). When pack.threads (or --threads=) is given a value of 0, the number of threads is set to the number of online CPU's. This feature is also documented. As per Nicolas Pitre's recommendations, the default is still to run pack-objects single-threaded unless explicitly activated, either by configuration or by command line parameter. The routine online_cpus() is a rework of "numcpus.c", written by one Philip Willoughby <pgw99@doc.ic.ac.uk>. numcpus.c is in the public domain and can presently be downloaded from http://csgsoft.doc.ic.ac.uk/numcpus/ Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 9c2174350cc0ae0f6bad126e15fe1f9f044117ab. Nico analyzed and found out that this does not really help, and I agree with it. By the time this gets into action and data is actively thrown away, performance simply goes down the drain due to the data constantly being reloaded over and over and over and over and over and over again, to the point of virtually making no relative progress at all. The previous behavior of enforcing the memory limit by dynamically shrinking the window size at least had the effect of allowing some kind of progress, even if the end result wouldn't be optimal. And that's the whole point behind this memory limiting feature: allowing some progress to be made when resources are too limited to let the repack go unbounded.

|/ | | | | | | | | | | | | | | | "git pack-objects" has the option --max-pack-size to limit the file size of the packs to a certain amount of bytes.

| | | | | | | | | | | | | | | | | | | | In the threaded pack-objects code the main thread and the worker threads must mutually signal that they have assigned a new pack of work or have completed their work, respectively. Previously, the code used mutexes that were locked in one thread and unlocked from a different thread, which is bogus (and happens to work on Linux). Here we rectify the implementation by using condition variables: There is one condition variable on which the main thread waits until a thread requests new work; and each worker thread has its own condition variable on which it waits until it is assigned new work or signaled to terminate. As a cleanup, the worker threads are spawned only after the initial work packages have been assigned.

* pack-objects: fix threaded load balancingNicolas Pitre2007-12-08
| | | | | | | | | | | | | | | | | | | | The current method consists of a master thread serving chunks of objects to work threads when they're done with their previous chunk. The issue is to determine the best chunk size: making it too large creates poor load balancing, while making it too small has a negative effect on pack size because of the increased number of chunk boundaries and poor delta window utilization. This patch implements a completely different approach by initially splitting the work in large chunks uniformly amongst all threads, and whenever a thread is done then it steals half of the remaining work from another thread with the largest amount of unprocessed objects. This has the advantage of greatly reducing the number of chunk boundaries with an almost perfect load balancing.

* | fix const issues with some functionsNicolas Pitre2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two functions, namely write_idx_file() and open_pack_file(), currently return a const pointer. However that pointer is either a copy of the first argument, or set to a malloc'd buffer when that first argument is null. In the later case it is wrong to qualify that pointer as const since ownership of the buffer is transferred to the caller to dispose of, and obviously the free() function is not meant to be passed const pointers. Making the return pointer not const causes a warning when the first argument is returned since that argument is also marked const. The correct thing to do is therefore to remove the const qualifiers, avoiding the need for ugly casts only to silence some warnings.

An ugly cast was added to the return of write_idx_file() to avoid a warning. A proper fix will come separately. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Shawn O.
