Are Fonts cached?

Hi,
I have a component that needs to reference many fonts objects to print text in various styles. At the present time, I create a new Font instance every time I need to change the style of the text, but many of these Font instances are similar and have a short life.
Are the font peers cached (or even the Font instances as the class seems to be immutable) or do I need to implement my own cache to reduce object creation.
--Pierre

Yes. Native font data is cached. Font objects aren't. So the performance boost from Font caching on program level should be minimal.

Where are the font caches located?

Trying to trash my font caches but cant find them.

It moves to the Trash all font cache.
Not quite. It clears any and all cache files of the user account you logged into in Safe Mode. It doesn't do anything to the system cache files.
All font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501 (Mac OS X v10.4 or later)
I know that info came from one of Apple's own Knowledge Base articles, but it's completely out of date. The user font cache files haven't been in that location since Tiger. All font cache files (along with Font Book's database) are now deeply buried in a hidden folder. Part of the name may be different from Mac to Mac, but they are now here:
/private/var/folders/3K/3Kdt7kk4Ghim10j+GZwim++++TI/-Caches-/com.apple.FontRegis try/
Don't try and edit anything in here yourself. Use the command below to clear font cache files.
Close all running applications. From an administrator account, open the Terminal app and enter the following command. You can also copy/paste it from here into the Terminal window:
sudo atsutil databases -remove
This removes all font cache files. Both for the system and all user font cache files. After running the command, close Terminal and immediately restart your Mac.

Home Directories/font cache corruption

I have a network of about 30+ Macs which all have their user folders served from OS X Server (10.4.1). Users login to their accounts over the network from their systems sitting on their desks. The computers vary, Mac Minis, iMac G4s and iMac G5s.
All was very well until we upgraded all the workstations from 10.3.9 and 10.4.x to 10.4.5 then we started seeing trickles of font cache corruption. Now it's like an epidemic, everyone is seeing or has seen the problem, some just randomly, some everyday, some multiple times a day. It doesn't matter what hardware they are using.
One user in particular sees the problem everyday, sometimes a couple of times. For instance, at lunch they log out, leave the machine, come back and log in. Somwhere in that process the font cache becomes corrupt and Mail, Safari and Filemaker Pro 7 all exhibit font display problems.
I temporarily fix them by booting their system into Safe Mode and logging in as them which moves the font cache to the trash. I'll also delete com.apple.ATS out of /Library/Caches.
Some systems have had multiple fonts (I presume thanks to MS Office) and I'll resolve those with Font Book, I'll also validate the fonts and delete any that Font Book has flagged as unusable. I've even resolved fonts while in Safe Boot but the problem still persists.
I've even gone as far as just replacing the system with a new one in addition to ClamAV virus scans. There are never any virus' found and the problem evenually comes back.
Any ideas?

I saw this same problem when we upgraded to TIger last month. Fonts in Filemaker and a few other apps would appear garbled, and Word would report almost every font as corrupted. The fix was to delete the folder /Library/Caches/com.apple.ATS/ from the client machine and restart. My solution was to create a launchd .plist file that deletes the font cache folder when the client machine boots up, and also deletes the folder every morning at 2:30 A.M. just to be safe. I installed the launchd file on every client computer in /System/Library/LaunchDaemons/ and this seemed to solve the problem. I instructed our users to restart their computer if they were experiencing font problems and i haven't had any more complaints. Here is the plist file that i use: (I made it using Launchd Editor http://www.codepoetry.net/products/launchdeditor)
!!!BEGIN fontcacheclear.plist

5. Restart the Windows Font Cache Service.
Thank you!

Apple Mail / Font Cache Problem

Is anyone else experiencing problems with Apple Mail (4.2) and font caches? Recently the copy of Mail on my desktop Mac seems to find it increasingly hard to maintain both incoming and outgoing connections to GMail - it connects intermittently (if at all) although my internet connection is fine. Also my laptop (with pretty much the same configuration and with the same fonts) does not seem to have the same problem. As far as I can recall this only started after updating to 10.6.2.
There is no problem when I boot in Safe Mode.
The only work around that I have found so far is to clear the user & system font cache (using Onyx) and restart. This then allows me to send & receive for a short time until the problem occurs again. I have tried to check whether any of the system / library fonts have become corrupted but it appears not (according to FontDoctor). I am not experiencing any other font-related issues.
Any ideas as to what could be doing the damage or at least how I might try to track down the cause of the problem?

MacBook Pro, !0.8.2
Mail > Preferences > Fonts & Colors
There are options available for messages.
Click the "Select" button.
A window will pop up and from that font size can be selected.

FAQ: How do I clear out my font cache to fix font style and duplicate font style issues?

We have a Script availabe for CS6 beta users who are experiencing particular font related issues.
This script will help by clearing the font cache and will test for corrupted fonts.
This will solve some of the type issues with duplicate font names and some of the other font errors.
This script is to help to find corrupted fonts. The script itself doesn’t solve the problem.
This script doesn’t solve duplicate font name, but clears out your font cach . It it will solve some duplicate font style name issues such as the one in the link below.

There is a pdf file explaining how to use the script and what it will do.

Monica, I know the Normal Character Style in Illustrator must be defined. But my question is about the Normal Paragraph Style, not the Normal Character Style. As Larry just said, in most of my documents, and in my New Document Profiles, these fields in the Normal Paragraph Style are blank (undefined), so I know this is possible. In a few older documents I'm converting, the Normal Paragraph Style has a defunct font, and even though my Normal Character Style is correctly defined with the current font, it's creating some weird behavior.
Larry, it doesn't appear to be the document itself, it just appears to be not knowing what the right keystroke combo is to clear it. Just make a new file from a Document Profile where the Normal Paragraph Style does not define one of those font fields, define a font and/or font size, save, then reopen the paragraph style settings and try to clear any field that has been set. I can't clear it, I can only change the font.

Rebuilding the font cache on OS X

I have been having some font issues. Not too long ago, I went through my fonts on font book and started resolving duplicates. I did 'accidently' delete some fonts, but I don't think I deleted anything crucial.
So far I've been experiencing 2 problems.
1) Macromedia Flash MX isn't displaying all my fonts. It said to follow the instructions on this website:
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_16763
Basically, it was instructions to rebuild your font cache, but I couldn't find the files they were looking for (com.apple.FCacheLocalDomain, com.apple.FCacheClassicDomain, com.apple.FCacheUserDomain)
2) When I click on a message in Apple Mail, the top of the e-mail gets cut off. I'm not sure if it's a font issue or something else.
Please help!
Thanks,
Catherine

Hi Catherine,
Font Finagler will remove all font cache files for you. Though you may need to remove the cache files for Microsoft Office manually. They are located at:
~/Library/Caches/com.microsoft.browserfont.cache
~/Library/Preferences/Microsoft/Office Font Cache (11)
The tilde (~) indicates your user account.

Font Cache

I work in a school, and in one of the labs the font cache is becoming corrupted. I have never had this issue with CS4, 5, 5.5 or 6 only Just started occurring in Photoshop CC 2014.2.1, even 2014.0.0 didn't do this. Can anyone explain why this would be occurring? The fonts are stock standard Windows 8.1 fonts + Office 2013 + CC 2014 design and web suites.
I just ran the FontTest.jsx tool (which by the way Adobe, this needs to be updated to support CC 2014 as it errors on clearing the font cache.) and it says that all fonts failed with (Font size error).
It says this for every font:
- Font Test Result: FAIL
The typed font size (12 pt) is not expected font size (10).
I have told staff to switch off font previews for now which alleviates the problem, but this is only superficial fix. I want to know why this is happening.....
Thanks

Have you tried manually deleting the Font Cache? Reference: Troubleshoot fonts | Photoshop CC 2014, CC, CS6, CS5
Windows
Exit Photoshop and the Creative Cloud desktop app (if installed).
Navigate to the appropriate folder
Photoshop CS6 and earlier
Windows XP: \Documents and Settings\Local Settings\Application Data\Adobe
Windows 7: \Users\[user name]\AppData\Local\Adobe
Photoshop CC and CC 2014
Windows 7 and 8: \Users\[user name]\AppData\Roaming\Adobe\Adobe Photoshop CC or CC 2014
Delete the TypeSupport folder (Photoshop CS6 and earlier) or the CT Font Cache folder (Photoshop CC and CC 2014), and empty the trash.
Restart Photoshop and test to determine if the problem recurs.

Does Safe Boot clean font caches?

I found this in the OS10.4.11 Help file under Safe Boot:
"Mac OS X 10.4 Tiger only: It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501."
Someone in another forum tells me that it isn't true. Is it?

So, if there were more than one user account, safe boot will only clear the font cache for the user who logs in while in safe boot. And if you then logged in as another user, it would clean out that cache (not that this is what people would normally do, but I'm just trying to understand all of this).
But, the system font cache is not affected, right? So if I suspect a font cache is causing problems, leaving the system cache unchanged might not relieve the problem.
You've got it!
Rather than trying to track all of the various font cache (and other cache files) yourself, there are free utilities you can download that do all of the work for you. Font Finagler clears just font cache files. If you want to clear other cache files at the same time, OnyX can do that.

"medit .fonts.cache-1" - system freeze!

:shock: :shock:
what's goin on here?
ive tried(!) to open the ".fonts.cache-1" file with "medit" and BAM! nothings working, X immedeately seemed to crash. the only thing i saw after doublecliking the file was colors in lines and a bit of black/white (like on tv..) all mixed, only crap to sum it up and the only thing i could do was a press on the reset button!
is this a bug in medit? ... why the whole system freezes then?, thats pretty ugly imo :oops:
what data may be destroyed ? can it be?

Can you SSH in from another box? Crashes are one of X's annoying features, the server can sometimes freeze up and deny all input even while the rest of the system is running fine.

[Solved] How to generate 32bit font cache in a 64bit multilib install?

According to fc-cache's man page, "fc-cache must be executed once per architecture to generate font information customized for that architecture." My question is, how can I do that?
Should I build a chroot and mount the font directories in the chroot and run fc-cache -s? Is there any cleaner way to do that? Btw, the lib32-fontconfig in multilib does not provide something like fc-cache32, it's only libraries.
Last edited by AugustePop (2013-07-02 04:50:35)

I'll repeat it again and the last time: this is not how a multlib capable environment works. Using multilib means that atop a primary architecture (which is determined by your CPU type -- x86_64 in this case), you can execute binaries built for a different architecture (i686). Since either one uses its own instruction set and libraries, you cannot install both at the same time. That's why there is no 32bit-fontconfig in lib32-fontconfig: it there were, you'd be running a i686 OS and didn't need multilib. However, you can enable native 32bit libraries to make it possible for a binary to communicate with the OS (and CPU) using its own instructions. That's why you can execute any 32bit binary, including the redundant fc-cache that you built yourself.
In your particular case, the binary needed to create font cache is the one you already have: /usr/bin/fc-cache. If you launch a 32bit application, the cache will be created for fonts the application needs (not your entire font collection), using the very same fc-cache: this is what happens when I run wine in a 32bit chroot and this is the answer to your question:
i just don't know how they got there and how to manually create the complete font cache.
And that's it: go to the next step and run your 32bit software. You'll certainly see it's using your fonts.
What you are trying to do is neither necessary, nor technically correct, but if you want to reinvent the wheel -- good luck then.

Are fonts in Keynote displayed in pixels or points?

Are fonts in Keynote displayed in pixels or points?

An interesting point which I never considered since I create my own designs using CSS.
I have always assumed that its pt. since we're taking print media here. This seems to be the case since the author of this Apple Training series book presumably knows!

Select the entire body level text box and change the font to Gill Sans, Regular, 36 pt. Make the font color the same dark red that you stored earlier.

Security Questions are getting cached

Hi,
We recently discovered that our security authentication answers are frequently cached by web browsers. Is there something we can do on the server side to stop this? We have several public terminals used for claiming accounts and changing passwords, etc.. When a user loads the change user answers form, and starts to type in an answer, the form will try to auto-complete the answer, and display other similar answers that people have submitted.
I tried setting the autocomplete property, but IDM does not support it on text fields it seems. I then changed the fields to html elements and modified them so their html output is the same as when they were text field objects. However, the form stopped working then. It no longer saves answers if I do that.
How have people addressed this before? It seems like it would be a security concern for any IDM installation that has a public terminal available for changing passwords / etc..
Thanks,
Jim

There are a few browser level settings I found that help. In firefox you can choose a setting that is title something like "Remember form fields and search bar entries". Making sure it is not checked will stop the auto complete. In IE there is a "Do not cache data from a secure connection" or something similar. That helps to. At the html level there is also an attribute for form elements called autocomplete. So you can set autocomplete=off for the elements.
John, the form I am working with is security questions. The name of the fields are the IDs of the questions. So I can't really make them dynamic.
The fix wasn't the greatest. IDM does not yet support the autocomplete attribute. When I manually added it to the text form field object, it generated an error when I viewed the form. When I changed the field object to an html object, and dictated the html, the workflow to save the answers stopped working. Ultimately I had to do a search and replace in the html in the JSP to add the autocomplete attribute.

Page-embedded Javascript and uploaded images are not cached.

Hello All,
I was reading in Wiki APEX and I found this line mentioned as cons: "Page-embedded Javascript and uploaded images are not cached".
The question that I have posted many questions here how to enable the cache for Images and Javascripts but didn't get it right, is the wiki info right about the cache for images and JS?
thanks,
Fadi.

Look at the bottom of this page as well [http://carlback.blogspot.com/2007/12/apex-and-3rd-party-js-libraries.html]
Patrick Wolf
Carl,
the only drawback with #WORKSPACE_IMAGES# and #APP_IMAGES# is that it doesn't get cached by the browser. So each page request will transmit the hole file again. A caching option for the "Static Files" in the Shared Components would be nice :-)
About lazy loading with the #WORKSPACE_IMAGES#. I could think about a mod_rewrite rule which translates the additional file request of the JS library into a valid request for APEX.
Carl Backstrom
In 3.1 we emit a last modified header now for uploaded files so that should help with browser caching.
I wonder if anything's changed since then.

Compilation errors are being cached??

Hi,
I am having a hard time getting rid of some cached compilation errors, that don't really exist. I am doing clean builds of the project and there are no errors, till the build reaches 100%. After 100% it throws 23 errors all of a sudden. The errors are actually non existing. Examples are:
Invalid Embed directive in stylesheet - can't resolve source 'Embed("../assets/images/addBtn.png")'.
1119: Access of possibly undefined property includeInLayout through a reference with static type com.xxx.xxx.xxx.xxx.view.component:MyProgressBar.
Both the errors are vague as the button image is present in the given location and also the MyProgressBar component is having the includeInLayout property. I can see it through content assist.
I have been getting these errors earlier as well but they used to get resolved if I do a Clean Build. This time they are not going at all.
After some directions, I also tried deleting .markers file, but it didn't help.
Please help me out!!
Thanks,
Saurabh

Check the syntax of the Embed request and verify you can use a static reference to that property.
Note the difference between -
MyProgressBar.includeInLayout
and -
var progressBar:MyProgressBar = new MyProgressBar();
progressBar.includeInLayout
It also might be an import issue, meaning you are trying to use MyProgressBar without the line -
import com.xxx.xxx.xxx.MyProgressBar;
I don't think compilation errors are being cached and they normally have a good reason for them.
I strongly suggest to identify the root cause of the errors and fix the problematic issues.
