There's probably some documentation on the wiki, but Firefox will be recording the time elapsed between when the app is launched and the session is restored and presenting this on a graph at about:startup.
So far I've implemented the unix and windows platform specific code, storage database code, the about redirector entry, and started the about page. There's no graph yet; it just displays a chart.

These should have localization notes ( https://developer.mozilla.org/en/Localization_notes ) explaining what the variables are likely to contain, so that localizers know what to do with them.
Also, Dave's question is an interesting one - can this live in toolkit? Not a deal breaker if you are currently relying on Firefox-specific code, but I think this should be pretty toolkit-generic?

Pike/l10n: This is work Daniel's doing on an about:startup page to let users see their startup-time history. It should be basically user-invisible, you'd have to know to go to the URL, but it's potentially helpful for troubleshooting.
It's not a blocker, just an opportunistic landing that should be well isolated from other things, but I wanted to make you aware regardless.

Nope. In fact the meat of the code is in toolkit; I'll move the ui code there as well. I am using the browser's AboutRedirector though.

Done, although I wasn't going to make the table very prominent. Graphs are prettier :)

Is there a reason to use microseconds instead of milliseconds? I think it's not really useful to have that precision in the data.
Reporter | ||
Comment 8•14 years ago
|
||
NSPR timestamps are always in microseconds, even if the timer functions such as PR_Now only ever store milliseconds in them. I intend for the graph to show milliseconds. Actually, on linux the data won't even be precise enough for that, since the launch timestamp is only known to within one fiftieth of a second.

<!ENTITY chart "Table">
is generally not good, use good variable names?
On the overall concept, I don't think we should pre-land strings. Less so for things that aren't blockers. We'll just end up with un-used strings on stable branches that then don't match what's actually used in the upcoming release because things evolved.

Axel: we're pretty close to having this work come in after beta 6, it's extremely low risk and extremely high value, so while I've been professing the same thing as you in comment 9, this is a case that I think warrants an exception.

improved strings
As a coding-style comment, Axel's right; we should be naming the entities a bit more descriptively, such as
<!ENTITY about.startup.title "String goes here">
Design-wise, I think these are the strings we want to use:
Start Time
Most Recent Start Time Elapsed Time
&brandShortName Launched
&brandShortName Started
&brandShortName Ready
_Graph_ | _Table_
Past Starts Launch Time Start Time Ready Time
note that by default we're going to move away from session restore on startup, which is why I'm renaming that to "ready" and "ready time" - the delta between when the application "starts" and when "startup" is complete. Hopefully that makes sense.

Thanks Daniel,
Can we get a version of this patch that is absolute, instead of relative-to-your-last-patch? These should all be net-new strings (and files, iinm) so it's odd (and maybe hg-import-unfriendly) to see +/- diffs.

improved strings (combined diff)
We'll need localization notes in aboutStartup.dtd to explain the subtle differences between launched, started, ready, launch time, start time, elapsed time. They're all similar concepts and can easily be confused.
Also, it'd be nice to have an introduction comment in the file that mentions that this is about:startup, so that once people can test, they can test.

Also, looking at it with a fresh profile (instead of the one I've been testing in for two weeks), the graph looks very empty. Perhaps it shouldn't try to show 7 days worth if there isn't enough data.

1) What's the difference between launch time and startup time?
2) I think about 1000 ms should be scaled to in seconds in the graph and seconds and minutes in the table
3) I think there is way too much detail in the timestamp. I don't think the day or the week, -400 GMT and the time zone are needed. Why would the user need to know (or care) about any of that?
4) I know this is way out of scope but looking at that big spike gave me the idea that maybe the user can be notified of what happened that caused a huge spike (huge sessionstore, recently installed extension, etc.)

Launch time is the time that you clicked on the Firefox icon and your OS started loading the executable. Startup time is when the OS handed control over to Firefox. I don't think a help bubble explaining that would get in the way, do you?
> 2) I think about 1000 ms should be scaled to in seconds in the graph and

Yes, that's a good idea. I think the table will stay in milliseconds, since the idea is that the table would be most useful for direct comparisons of the values, and rounding would hurt that.

Ah, true. We should show the date in the user's locale in any case.

Yes, it would be nice if we could always tell. Currently it'll show a vertical bar whenever the app version number changes, and tomorrow it'll show vertical bars for when you install or uninstall extensions. You can see numerous grey bars that mark minor upgrades, changes only to the build id that happened each time I rebuilt my Firefox. Each of those is accompanied by a large spike, although not every such spike is the result of a rebuild. You can see that spike of 200,000 ms (not a typo, that's 200 seconds) because I had bogged my system down a bit for testing purposes.

Generally, I'm not a friend to show linear graphs for stuff that is not, do the lines really help, compared to just data dots? It'd also make it easier to strip boring times from the graphs, and zoom in to times that had more restarts.

Oh, and if you've already run a build with this feature in it, you'll need to delete the old startup.sqlite from your profile. The schema changed slightly, and as yet there is no code to handle a schema upgrade (doesn't seem necessary at this point.)

bsmedberg: the vast majority of this patch is tests, fwiw. Also, startup time is one of our key metrics and competitive differentiators. I'll finish the ui-r tonight, but I think we should try to find someone to look over the 200 or so lines of code in the startup path here.

This is great. I'm not really convinced in there being a ton of value in the graph, but there's no real reason to remove it at this point (unless the code reviewer feels that it would simplify their task, I suppose). Really glad you got the event entries for add-on install and session restore. I can't tell from inspection: are those also being added to the table of events, or just the graph?
An added bonus would be an export data option, but not worth adding the strings.

To clarify Blake's comment: It would be extremely valuable for our Test Pilot analysis to be able to query nsIXULRuntime.launchTimestamp, .startupTimestamp, and .restoredTimestamp. So I strongly hope that at least the recording of those three timestamps will make it in, whether or not the database and the about:startup page make it in.

This looks fine, though don't we already have jquery etc. in the tree? Can you take a look, and if so file a bug to stick them all in one place that we can reference via a chrome URI or something?
Also, nsIAppStartup.idl and nsIXULRuntime.idl both need IID bumps.

Thanks Vlad! I'll look again to see if we already have jquery in the tree; so far I've only seen it in the Test Pilot extension and some tests. At any rate, this patch does make a separate chrome package for it (see the chrome://jquery/content/ urls.) The files still live in toolkit.jar though.

This is currently really a browser-specific event, so I'm not sure it makes sense to put it on nsIAppStartup...

I think you only want to observe sessionstore-windows-restored. browser-state-restored can fire in non-startup cases (e.g. for private browsing transitions, IIRC).

This will return 0 if called before the restore has completed, right? That should be documented, at least... Looks like it can also affect about:startup loaded before the restore is completed.

This should use Services.obs. But this method doesn't seem to be called? Given that, I think you should split it off to a followup bug (along with the relevant nsAppStartup code) - Mossop should review changes to the addons manager.

Well, the only thing browser-specific about it is the name of the observer notification that we listen for. Every app will have some way of determining that startup has ended and the app is ready to use. I guess I could rename it to readyTimestamp if you want.

It doesn't get called before the timestamp has been set, I've tried it.

Ah, yes. Last night as I was going to sleep I thought I might've forgotten to pull this change in.

Comment on attachment 485730 [details] [diff] [review]
fixes review comments
This needs superreview for idl changes.
Also I think you should move jQuery to a separate patch, since it does not need code review but it's a large part of this patch
I was asked to skim through the database stuff, this I'm just looking at it. If anybody needs me to do a global pass, let me know.

when doing INSERTs always specify fields please,
INSERT INTO table (field1, field2, ...) VALUES (?1, ?2, ...)
this makes easier future ALTER and also increases a lot the readabiity of the insert (preventing binding errors)
You want to use CreateAsyncStatement here
this call seems to be too high in the method, move it just before using the statement.

No, you should never ever use synchronous statements, especially in the startup path.
This must use executeAsync.

I'd rather make this mozIStorageConnection* GetStartupDBConn(), save the connection in a local property mDBConn and NS_ENSURE_STATE result of this getter.
You most likely want to open only one connection and to close it when done, for performance reasons.
This will require some refactoring though.
The better way to handle this for performance would be:
1. collect information
2. open db connection
3. executeAsync all statements at once
4. close db connection
while you currently open a db connection for each statement, execute statement (synchronously :( ) and let connection die.
Probably (3) is hard to do for addon events, since looks like they can come at any time during app life, but you could close dbConn at profile teardown.

you should cast to (void) anything that you explicitly don't error check.
Btw, will you really find useful the corrupt backup? From my experience once you get the corrupt db, it is just unreadable and with low value.
Places got issues like backups created in loop when the file was corrupt in such a way that it was un-movable (due to antivirus often), thus you keep backing up and opening creating tens of backups a day.
We workarounded the issue by checking to not save more than 1 backup per day, but actually data in this startup database don't seem sensible enough to require a backup at all, I'd just delete the corrupt db and make a new one.
>+ rv = svc->OpenDatabase(file, db);

>+ NS_ENSURE_SUCCESS(rv, rv);
the first NS_ENSURE_SUCCESS is useless, you have replaced rv already, the external one is the only one needed.

see above, btw this is not exposed to XPCOM thus it would be much more readable returning the connection pointer rather than a nsresult.
>+ rv = EnsureTable(*db,
>+ NS_LITERAL_CSTRING("events"),
>+ NS_LITERAL_CSTRING("timestamp INTEGER, id TEXT, name TEXT, version TEXT, action TEXT"));
>+ NS_ENSURE_SUCCESS(rv, rv);
actually if one table exists it's most likely that the other one exists as well, the EnsureTable helper seems to make everything less readable, and the tables strings should be formatted properly, e.g.
timestamp INTEGER
, id TEXT
, name TEXT
...
I'd just make this include all needed code for tables check and creation, you probably want to use SetSchemaVersion too to make easier future changes.
I'd not name a column "ID" since it's most likely to be confusing (usually id is considered the primary key of the table, that is the alias for ROWID)

always brace ifs please, per code style
Notice that having a global dbConn will require you to call asyncClose() on it before shutdown.
As a side note, I don't know how often you could get an add-on event, if that's often you could want to have a cached prepared statement too, but could be a followup in case it's found needed.

f- because of the sync stuff we are running to populate the tables, those are going to hurt due to fsyncs on the main-thread.

I think that would be better, yeah. Also, it would probably be better to have the app call RecordStartupDuration() itself, rather than having the core code watch for a browser-specific topic.

It was for me, when about:startup was part of a session being restored.
I still think it would be best to split the addons change into a followup.

Certainly. I've run it through the try server twice this week. Use builds from http://stage.mozilla.org/pub/mozilla.org/firefox/tryserver-builds/db48x@yahoo.com-c6e28dd6326c/ if you're on a mac, otherwise use http://stage.mozilla.org/pub/mozilla.org/firefox/tryserver-builds/db48x@yahoo.com-8ad67554aadd/. Visually, however, not much has changed :)

I'll gladly change it to a different observer topic, if there is a suitable one. Otherwise, I had been planning on a followup bug specifically to add an app-neutral topic and make Firefox, Thunderbird and Seamonkey all use it.

Odd, I can't reproduce this. What is the value of browser.startup.page in that profile?
> I still think it would be best to split the addons change into a followup.
Perhaps, but Marco was able to review the database code without having a separate bug, so I don't think it'll be necessary for the much smaller change to AddonManager.jsm.

The second part of my comment was meant to suggest not using an observer topic at all, but rather having Firefox code call RecordStartupDuration directly (perhaps from one of its browser-state-restored observers). IOW, apps would be required to call RecordStartupDuration themselves to opt-in to the tracking.
I know that it's _possible_ to review everything in this bug, but I don't think it's ideal, and splitting things up just helps get the core parts landed sooner. I won't belabor the point, but (core changes)/(about:startup content+strings)/(graphing+jQuery)/(add-on integration) all seem like separate steps that would be easier to review separately, and only the first two really need to get in to b7.

Yes, thank you for reminding me. I've put in the code to localize the dates that show up in the tables, but haven't done the same for the ones in the graph. Because of the way the graph automatically shortens the dates based on the extent of the axis, I'm not sure it's currently possible to do. Perhaps Thunderbird has some code that I can reuse, or perhaps I'll have to extend nsIScriptableDateFormat, but either way it can wait for a followup bug.

you should not need to finalize the statement, it will be finalized by executeAsync when it is destroyed

you can't close this way since you have an async statement running, use AsyncClose() instead.
also, error check.
the same comments are valid for RecordAddonEvent, thus I'm not going to repeat them again.

I still think making a backup of a corrupt database is a useless overkill here.
Plus looks like you are doing a copy of the corrupt db but not removing it, thus the next call to OpenDatabase will again try to open the corrupt one.
Indeed backup executes a copy, not a move.

you probably want to get schema version, and if < 1 ensure tables.
And so on, for any schema change, should be faster then checking each table.
finally set schema version to the current one.
Also, wrapping these 2 in a transaction will save you a fsync on startup and increase safety.

Oh, I had meant to comment. I still need to size the graph and set up the axes and so on even when there's a failure, so I'm just putting a message in the table when there is one. That's in handleError() though.

In the end I decided that using a non-ascii identifier (as allowed by the javascript spec) should be fine. No editor I've ever used has had any real problems with utf8 (although it does mess up the syntax highlighting provided by js2-mode in emacs), and well, this is supposed to be the future. I like the result enough that I'm willing to stick by it, accepting the future burden of maintenance it may or may not cause. I hope that this does not upset anyone. I hope also, Marco, that I can still claim your feedback+ even though I've kept it.

I'm a little ambivalent on the subject but shaver has said that we shouldn't be shipping jQuery such that extensions can start to rely on it. The problem is that it adds an additional maintenance and compatibility burden on us, for example we wouldn't be able to make stability/security fixes to about:startup that required a new jQuery version unless we were willing perhaps to port the appropriate jQuery fixes to the version we were already using. Perhaps this is a rare case but it's going to be fairly easy to change this to either put jQuery somewhere less exposed (where extension authors shouldn't rely on it) or to perhaps preprocess its code into the appropriate files.

So I know the Tab Candy team did some porting of jQuery to iQ (http://mxr.mozilla.org/mozilla-central/source/browser/base/content/tabview/iq.js)
It's not a drop-in replacement though so there would have to be more work done if that was the path to go down.

Hrm. Thunderbird ships a copy of jquery as chrome://messenger/content/jquery.js, but it doesn't seem to have caused them any problems.

Thunderbird are allowed to ship whatever they are comfortable with in their single application, we have to make choices about what ships in every Mozilla based application.
Note that as we are after API freeze you aren't going to be able to modify nsIXULRuntime so you'll have to create a nsIXULRuntime_MOZILLA_2_0 horror.
Who is going to be organising the security review for this feature?
Target Milestone: Firefox 4.0b7 → ---
Ugh. (Not directed at Mossop, just a general ugh.)
1 - If you need to, just copy and paste all of jquery into your JS. It's ugly, but honestly I'd rather have this data than not have it due to figuring out where jquery lives. You can probably get away with moving jquery.js into your own content dir; we don't make any promises about any compat there. Better yet, make it chrome://unstable-mozilla-private/content/jquery.js. If this needs to go into browser instead of toolkit, that's fine as well.
2 - Let's not create nsIXULRuntime_MOZILLA_2_0. Put those changes at the end, ask for sr, and let's just get this done.
I understand the need for API freezes and the like; but at the same time, let's ship the product that we actually want to ship, and not the one that we end up shipping because we enforce semi-arbitrary external constraints on ourselves.

Not a full review (the previous reviews stand) but yes this looks good to me now too, however regarding the changes to the IDLs I have to insist that we follow the current tree rules which means you need to email release-drivers@mozilla.org with risk/reward/probability of extensions using the interface (both JS and C++ extensions) so they can agree to making the changes without creating new interfaces.

As noted in r-d emails, we cannot accept .idl changes to nsIAppStartup or nsIXULRuntime now. But since the changes are additive, you should be able to add a new nsIXULRuntime_MOZILLA_2_0.

That's bad news. Care to share a link? I don't see anything on the graphs myself... perhaps I'm looking in the wrong place.

Ah, now I see. That is interesting. There's a clear 14% drop on a bunch of machines, but no corresponding jump earlier when I first checked in. One machine dropped 14%, then jumped back to the original level then dropped 14% again. Since my first push didn't cause a regression, I can't take credit for the improvement. Perhaps it was a fluke? Are there any better explanations?

Yes, here's the latest one: http://perf.snarkfest.net/compare-talos/index.html?oldRevs=0fdfcad343c6&newRev=fbb6749d4bdd&tests=ts,ts_cold,ts_shutdown&submit=true
It shows a 30% penalty in the startup test and 9% in ts_cold.
Then I did another test: http://perf.snarkfest.net/compare-talos/index.html?oldRevs=9e71d94198c9&newRev=fbb6749d4bdd&tests=ts,ts_cold,ts_shutdown&submit=true
This compares about:startup to about:startup with an empty startup.sqlite database in the profile. ts is now unaffected (yay!), but ts_cold is still slower by 9%. Unfortunately, that 9% is 700 milliseconds, which is insane. How can reading a 96kb database file take 700 milliseconds?
Also, I haven't been able to reproduce locally the crash (or crashes?) that mochitest-other triggers, so I don't know what that problem is.

Looks like loading the database happens during the first page loads, maybe it would be better to delay that until a few seconds or even minutes after startup.
Comment 94•14 years ago

notice that ts_cold has lots of noise, on Places branch we have noticed it is often changing with unrelated changes or even just merges. I'd care more on Ts regression. Also there is probably not much difference between what the db has to do in ts and ts_cold to startup.

Yea, I asked for some extra runs to see if that was the case. It doesn't look like I regressed that at all, now. I'll just add the empty file to the tinderboxes before I check in.
That only leaves the crash(es). Any ideas there? See http://tinderbox.mozilla.org/showlog.cgi?log=MozillaTry/1292300353.1292301811.14773.gz&fulltext=1#err6

It impacts the speed of loading the first pages by however long opening the database takes. Have we any measurements on how long that takes after it has a bunch of data in it?

I find it unlikely that four separate tests all improving on the same changeset (the back out of this bug) by about the same percentage (see comment 89) can be blamed on noise. There just aren't that many mails to tree-management about random increases and decreases in these tests for that to seem plausible.

Yeah on systems that I tried uptime was only precise to ~1second which threw off results a bit. glandium's approach is to track thread/process creation and use new /proc/.../stat relative the old one. That is extremely precise, but is unpleasantly cumbersome. Can be done in a followup.
nothing in /proc/* can be relied on on non-linux.

Daniel thanks a lot for taking on this project. I wasn't aware of this work and was merely planning to reimplement most of this for bug 585196. Really glad to see how far you got.
However there are a few issues with the patch, in addition to points raised by glandium.

This is the first useful ts_cold catch I've seen so far :) Lets avoid the ironic problem of startup-measurement code affecting startup.
Sqlite is a robust, but expensive way to store flat lists. IO like this should happen on own thread. It should also be delayed by a minute or so after startup. I don't think this can land as is.
I'm also a little concerned about adding a full copy of jquery to the tree. It's great to have startup-graphing functionality(especially on mobile), but would it be possible to write a simple graphing script or use a minified copy of jquery? Perhaps in a followup bug?
Comment 101•14 years ago
|

I am concerned that this could more negatively affect mobile startup and I'd like to not take such a large addition (codesize) too.
Why do we want to save data in sqlite? Why do we need to chart the data? Can't we just display the data in a table? Why not use an add-on to make fancy graphs?

Fair enough

Hmm. The worst I've seen so far was about 100ms. Anything that depends on jiffies is going to be pretty imprecise, but at least I figured that nobody would be adjusting their HZ very often, so at least the imprecision should be constant.

Is that code available somewhere? It sounds like it'd be more likely to work on OSX, where I tried and failed several times to implement this.

Yes, admittedly that would be ironic. The test just seems so noisy, swinging up and down by the same amount as the 'regression' over multiple runs with the same changeset. If it's a real regression, what's the best way to go about finding the cause?

The only reason I used sqlite is that parsing and serializing JSON takes longer the larger data is, and the third option was to implement a CSV parser. Or perhaps I could have stuffed the data into an ini file... I can always delay the IO, that shouldn't be too difficult. Plus, it's so easy to add more data to the same database in the future.

We've always resisted shipping minified javascript in the past. Writing another graphing script does seem like more work than it ought to be, especially considering the features that this one has. (The way it handles the time axis automatically is really nice, for example.) Perhaps a follow up bug for producing a version of jQuery customized specifically for Firefox, that doesn't do any feature detection, would help?

Well, you know that aphorism as well as I; a picture is worth a thousand words.
There's no technical reason why we can't ship the graphing as an extension, of course, but imagine how sweet it will be when someone asks why their Firefox has become slow, and you can have them visit about:startup and see the shape of the graph. Are there any large jumps? What extensions did you install that day?
So, to sum up, I'll look into delaying the IO a bit and then I'll do a larger run of ts and ts_cold tests. Bigger sample size means better data, right? I'm also getting ready to borrow a test slave from the pool; I really hope I'll be able to reproduce and debug the crash that sometimes happens during mochitest-other on linux/linux64.

I reworked your startup-measurement stuff in bug 522375 as that is more likely to land without trouble at this point.
Could you share some pointers on how to measure startup on osx?

Commenting out parts of the code :)
I'm pretty sure sqlite io was the cause.

I think that's cool. But a lot of this can be accomplished by having a link in some about: page or dialog that would install the measurement extension for you.
I think that's the way forward with this bug. An extension can evolve much quicker and with less constraints as long as the platform provides the core hooks.

This is cool. I see it tracks more information as well, which is a good thing.
> Could you share some pointers on how to measure startup on osx?
I started by reading the source of ps, but that was a lot less help than it should have been. Then I wrote an implementation using the api function GetTickCount and the information from the process info structure, but I couldn't find any real documentation on how long a tick is (or even if it's a consistent size, and the startup duration generally coming up either negative or in the dozens of seconds when it should have been 2-3. The functions for getting process information are fairly nice, at least, but nothing else about it was.

That may be the case, but I was contracted to provide a built-in webpage, so that's what I'm aiming for. Everything else is pretty flexible though, and I'll help in any way that I can.

Sorry, Dan - I recognize that there's a lot of good, hard work in this.

Could something be included which was equivalent to the very simple extension that Mike attached in comment 105? The current output is:
main 1622
sessionRestored 4049
firstPaint 4815
None of those strings need translating as they're just event names. There won't be any historic data, but for basic diagnosis of horrendous startup times it could help. For example I'm sure I remember seeing Taras or someone comment on a blog post saying that a user's time-to-main was very slow, although I can't find it now.

Yeah, have a look at http://code.google.com/apis/ajax/playground/?type=visualization#annotated_time_line

I'm really wary of sending this data to third parties; it's a list of the exact dates and times that you opened Firefox.

You could send deltas instead. We don't need the absolute times.

Quick drive-by: there are a lot of unrelated whitespace-only changes in nsAppStartup. That makes things harder to review, and generally isn't a good idea to do anyway. Seems like this could all just be JS code anyway...

For the record my extension is also available on https://addons.mozilla.org/addon/about-startup and has had various improvements since I attached the initial version to this bug.

no ui
Clearing review request on old bug. Is this still relevant with all the other startup work/telemetry that's been done? If not, let's close this. If it is, thne let's refresh the patch and request review from a specific reviewer to wrap this up.

I think this is still relevant in terms of users being able to see the data that they are sharing with Mozilla. The startup numbers aren't transmitted via Telemetry as far as I know (rather via one of the daily pings I think) so don't show up in about:telemetry.

I don't think about:telemetry shows them, but they are transmitted via telemetry.

So, this bug seems to predate the implementation of Telemetry. Seems like that's where we're going to get most of the value from (and if we need to add more data to Telemetry, then ok).
Is having a per-client record with UI is still worth doing? Especially if it's available as an addon (? comment 127). Bug 597282 seems like a more general solution, too.

If these are being sent via Telemetry then showing the data in about:telemetry would suffice I think. I thought about:telemetry showed everything that was being sent. I think it's important from a privacy perspective that it does so.
