And two, because various -calculation steps are left up to the server the entire process of -checking out code (should) be faster. - -But the svn measurements should be considered as what developers are -used to. Thus they act as a reference point for what people tend to -expect in terms of performance. - -Looking at bzr, I have listed two numbers. The first values are for -running ``bzr branch`` as outlined in the `One-Off Checkout`_ -scenario. When the -timings came back in hours (I used Launchpad as code.python.org is -not running the newest version of bzr and I wanted to use its latest -networking protocol), I decided to try using the steps outlined when -the experimental bzr branches were first created. That second -approach is what the second set of values for bzr represent. - -While both the hg and git numbers are perfectly acceptable, the bzr -numbers not necessarily. The raw ``bzr branch`` approach is entirely -not acceptable as no one wants to wait over two hours to write a -potentially one line change to some code for the benefit of Python. -Assuming 8:46 is a reasonable amount of time (I believe it in -general is, but it is teetering on not), the 596 M space requirement -could be an issue for some. While we typically view disk space as -cheap, for some people it might be an issue (e.g. the person who did -the schedule for PyCon 2008 did it over a connection so badly that -Google Spreadsheets didn't work for him and he had to submit the -schedule in another form than the one original used). Once again I -think the space usage is acceptable, but it is close to being too -much. - -To see if bzr's performance would be acceptable once at least the -branch was downloaded, I decided to see how long it would take to -get the change log for a file. I chose the README file as it sees -regular changes for every release and has a revision history going -back to 1993 and thus would have a fair number of revisions. -It should be mentioned that while git had the nicest output thanks to -its color terminal output, it also took a while to find the -``--no-pager`` flag in order to get just a stream of text instead of -having the output sent to the pager. - -Overall the numbers were all acceptable: - -* bzr: 4.5 seconds -* hg: 1.1 seconds -* git: 1.5 seconds - -While having bzr be over 3x slower than its nearest neighbor, it -must be kept in mind that the total performance time is still -acceptable, regardless of the multiplier. - -Because a DVCS keeps its revision history on disk, it also means -that typically they can be zipped up for direct downloading. At -least in bzr's case that would solve the performance issue for -initial checkout if the zip file could be generate constantly. But -that didn't address the cost of pulling in new revisions when a -checkout has gone stale. To measure this I decided I would check out -the repositories back about 700 revisions which represented the -amount of change made since the beginning of the month and time how -long they took to update. - -For this to happen I first had to remember the URLs for the -repositories. Instead of simply looking in this PEP, though, I -decided to try to figure it out from the command-line help for each -tool or simply guessing. Bzr worked out great with ``bzr info``. Git -took a little poking around, but I figured out ``git remote show -origin`` told me what I needed. For hg, though, I couldn't figure it -out short of running ``hg pull`` and denoting the status information -during the pull (turns out ``hg paths`` is what I was looking for). - -With the repository locations known I then had to perform a checkout -to a certain revision. Turns out that git will not clone a -repository to only a specific revision, although from personal -experience git's pull facility is very fast. Bzr was able to perform -its update in just over 39 seconds. Hg did its update in just over -17 seconds. Much like the log test, while the multiplier of slowness -seems high, in real life terms al DVCSs performed within reason. - -In my mind this means that bzr is only an acceptable candidate as -long as an fairly up-to-date archive of Python's key branches are -made available for people to download to avoid bzr's very so remote -branching. +.. note:: + The *bzr 1* entry is for + following the instructions in the `One-Off Checkout`_ scenario + instructions pulling from Launchpad_ in mid-January. + The *bzr 2* entry is based on following the instructions + for the `experimental Bazaar branches + <http://www.python.org/dev/bazaar/>`_ and pulling from + http://code.python.org/python/trunk/. + +When comparing these numbers to svn, it is important to realize that +it is not a 1:1 comparison. Svn does not pull down the entire revision +history like all of the DVCSs do. That means svn can perform an +initial checkout much faster than the DVCS purely based on the fact +that it has less information to worry about. + + +Performance of basic information functionality +---------------------------------------------- + +To see how the tools did for performing a command that required +querying the history, the log for the ``README`` file was timed. + +==== ===== +DVCS Time +---- ----- +bzr 4.5 s +hg 1.1 s +git 1.5 s +==== ===== + +One thing of note during this test was that git took longer than the +other three tools to figure out how to get the log without it using a +pager. While the pager use is a nice touch in general, not having it +automatically turn on took some time (turns out the main ``git`` +command has a ``--no-pager`` flag to disable use of the pager). + + +Figuring out what command to use from built-in help +---------------------------------------------------- + +I ended up trying to find out what the command was to see what URL the +repository was cloned from. To do this I used nothing more than the +help provided by the tool itself or its man pages. + +Bzr was the easiest: ``bzr info``. Running ``bzr help`` didn't show +what I wanted, but mentioned ``bzr help commands``. That list had the +command with a description that made sense. + +Git was the second easiest. The command ``git help`` didn't show much +and did not have a way of listing all commands. That is when I viewed +the man page. Reading through the various commands I discovered ``git +remote``. The command itself spit out nothing more than ``origin``. +Trying ``git remote origin`` said it was an error and printed out the +command usage. That is when I noticed ``git remote show``. Running +``git remote show origin`` gave me the information I wanted. + +For hg, I never found the information I wanted on my own. It turns out +I wanted ``hg paths``, but that was not obvious from the description +of "show definition of symbolic path names" as printed by ``hg help``. + + +Updating a checkout +--------------------- + +To see how long it takes to update an outdated repository I timed both +updating a repository 700 commits behind and 50 commits behind (three +weeks stale and 1 week stale, respectively). + +==== =========== ========== +DVCS 700 commits 50 commits +---- ----------- ---------- +bzr 39 s 7 s +hg 17 s 3 s +git N/A 4 s +==== =========== ========== + +.. note:: + Git lacks a value for the *700 commits* scenario as it does + not seem to allow checking out a repository at a specific + revision. + +Git deserves special mention for its output from ``git pull``.
