Re: [Evolution-hackers] Memory consumption and virtual machines
Hi all, I second fejjs thoughts. Also i have been testing the patch for sometime now. Heres the inference: * The patch works in reducing the memory consumed during the initial startup of evolution. And it does a wonderful job of that. * The patch intends to fix the overall consumption of memory during the usage of evolution, and it does *not* do that. I kept evo running with this patch in for more than 8 hours and using Evo as i would use it regularly. (Reading of new mails, changing foldersblah! blah!) and more than a couple of hundred new mails later and modifying the summary file as many times we lose the memory gain we got initially. I *dont* have fancy graphs to display this information though - but i surely have the data and the necessary information i need. * mmap is *not* the solution to this problem - it helps to a certain extent. * Generating message list each we get a new message is bad enough - we dont want to reload the summary file each time. I still have not tested philips latest patches. I gather he has improvised on the older patches. Would report on the patches after i test them enough.

What about making an internal little tool that converts any summary file it detects to a summary.mmap file, and after that never touches the original summary file. This will allow the format of the mmaped summary file to change, and only an evolution with the mmap patches will only the first time have to perform things. We can also simply change the file-name and let the older evolutions continue using the "summary" file, and the mmaped evolutions the new file. The older evolutions will not accept any changes to the summary files (for example version changes). They will reload the summary file if it has defects it can't handle, however. > 3.

I've been talking to Philip on IRC, and gave him these requirements for his patch: 1. Don't change the external ABI of Camel, so that Evo needs no changes, *OR* also submit a patch to update Evo for the changed API. 2. Make sure the summary format on disk works with older Evos without making *them* rewrite the summaries.

My own tests indicated that it's as-fast as the old implementation. Some test (like sorting) where even faster. I'm guessing mostly because qsort doesn't make large jumps afaik.

Re: [Evolution-hackers] Memory consumption and virtual machines
I have to wonder if it's even worth ever merging the mmap hack into Evolution at all. If the plan is to finish Zucchi's disk-summary branch, which also solves the memory problems (afaik) as well as: 1. introducing an API for using cursors to get at message infos 2. better designed on-disk format that uses B-Trees the problem with philip's mmap file format is that the strings that will be hit for sorting/viewing/etc are all spread out over a huge number of pages. I just see this being re-examined later to try and design the format to better optimise it by compacting all the strings into a strtab type thing. I also don't like how it has to reload the summary anytime new messages arrive. I just don't get the feeling this is really all that well thought out and it scares me.

It wouldn't be a good idea to glue this patch to an API freeze or GNOME release cycle as it needs extensive testing that shouldn't be bound by such milestones, but should be bound by test results. The test results have to be done on installations that I don't own. I cannot perform these tests with just my own equipment. I don't have customers that run Evolution on a NFS shared $HOME or run Evolution 4300 times on an application server. I guess this is why you wanted it to be optional. I'm still waiting for your decision of that "optionality" being at compile time or at run time. Note that at run time means that more errors and bugs are possible (especially when switching the implementation happens). Also note that after a full week of night-hacking on this patch, you have to remember that I'm not getting paid to do this.

I don't know how many times I need to repeat, because, this keeps coming in lot different threads and I see no progress to make the patch complete. Yes, I agree, the patch does reduce *STARTUP-MEMORY-FOOT PRINT* of Evolution as mentioned by Federico in his blog, however, it is *as of now* just-a-hack that the Evolution team cannot take it *as is*. Phillip, as you keep saying the patch needs rework before considering upstream, when are we going to get it? Will the final-patch addresses all the concerns raised by me and Fejj? Guess, you are aware of the GNOME release cycle and API freeze dates. V. Varadhan Novell, Inc.
