Now if I try to do the hard link manually:

 

link

~/.fonts.cache-2/mike

link: cannot create link `/home/Mike/.fonts.cache-2/mike' to
`/home/Mike/.fonts.cache-2/d62e99ef547d1d24cdb1bd22ec1a2976-le32d8.cache-3.T
MP-Wl6CrD': Operation not permitted

bash-3.2$ echo $?

1

 

 

I checked my umask and stuff and that looks fine; also nothing in
FcAtomicLock changes the umask, so if it can create the temp file (and it
can) it should be able to create a link to it in the same directory. 

 

Maybe this is  a Cygwin limitation, hard links are not allowed?  I think
this may have to be done with directories on Cygwin.

Looks like I can replicate the problem now; its trying to write the cache
but the call to get a lock is failing, this code:

 

FcDirCacheWrite (FcCache *cache, FcConfig *config)

.

    if (!FcAtomicLock (atomic))

        goto bail3;

 

Is leading to a silent failure (just returns false), i.e. bail3 gets
executed.  I'll try to dig a little deeper, maybe my Cygwin is not doing
locks right or something.  Would have been nice if there was some kind of
visible error message about this.

Some how (not sure how), it is managing to get through to the section of
code where it actually tries to write out to disk.  But.that is failing as
well.  I'll dig deeper to see if I can identify why the default Cygwin
binary is getting to that stage and the one compiled from source is not.  I
think the Cygwin one might be patched somehow.  Still fails though L

Subject: [Fontconfig] fc-cache does not work with Cygwin

 

Hi, I've been trying to fix the problem with all of my Cygwin (Widnows XP)
Gtk and Qt applications being slow (taking about 5minutes to startup).  I've
been able to verify that the issue is due to Freetype being used, and in
turn; font-config being used to list off the available fonts on startup. The
problem is that font-config never actually caches anything, so any
font-config using application, has the same (realliy bad) start up
time.every time.

 

I tried running fc-cache manually but to no avail; I double checked time
stamps, having write permission any problems with the configuration file,
bad install of the Cygwin packages etc, but no matter what, fc-cache always
fails on all possible font directories with:

 

  failed to write cache

 

After googling around trying all the suggested solutions, nothing was
helping, and I ran strace and looked through the detailed system calls.  It
turns out fc-cache tries to open cache files in read only mode.    Which
means there is no way it can create cache files L 

 

So, I downloaded the source, compiled it up and added printf statements
throughout the call chain from scanDirs() downwards, and picked a single
directory to try and cache (the Type1 fonts directory for Cygwin).  This is
what I see:

 

bash-3.2$ ./fc-cache.exe --force --really-force /usr/share/fonts/Type1/

X: FcDirCacheValid /usr/share/fonts/Type1

X: FcDirCacheValidConfig calling through to FcDirCacheProcess

X: FcDirCacheProcess
cache_base=/d62e99ef547d1d24cdb1bd22ec1a2976-le32d8.cache-3

X: FcDirCacheProcess
cache_hashed=/home/Mike/.fonts.cache-2/d62e99ef547d1d24cdb1bd22ec1a2976-le32
d8.cache-3

X: opening
/home/Mike/.fonts.cache-2/d62e99ef547d1d24cdb1bd22ec1a2976-le32d8.cache-3
O_RDONLY | O_BINARY

X: FcDirCacheProcess fd=-1

/usr/share/fonts/Type1: failed to write cache

bash-3.2$

 

The X: . lines are my printf statements I added to the code. 

 

I looked through the code by hand, from main(), to scanDirs() and downwards,
there is no possible way that I can see for fc-cache to actually create
caches on disk.   The code that prints out the failed to write cache message
is just calling FcDirCacheValid(), but this function is not used to create
cache files (the error message of "write failed is meaningless), only to
open then and check that they are valid (hence strace shows opening of cache
files in read only mode with no creat flag..consistent at least).

 

So from what I can tell, fc-cache is not the program to use to populate the
font caches the very first time.  

 

My question is, what program do I use?  Can you update your documentation to
correctly point to the right program to use?  

 

This has been very frustrating to try and track down.   I guess when I have
time next, I'll try to understand the "init" call tree that actually does
call the functions which build cache files (FcDirCacheScan), and maybe write
a little program that specificalliy calls those functions so I can get my
caches populated, but I really don't think I should have to do that.
fc-cache should work as its manpage says L 

 

(^_^)/

Mike.

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>Hi, I&#8217;ve been trying to fix the problem with =
all of my
Cygwin (Widnows XP) Gtk and Qt applications being slow (taking about =
5minutes
to startup).&nbsp; I&#8217;ve been able to verify that the issue is due =
to Freetype
being used, and in turn; font-config being used to list off the =
available fonts
on startup. The problem is that font-config never actually caches =
anything, so
any font-config using application, has the same (realliy bad) start up
time&#8230;every time.<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>I tried running fc-cache manually but to no avail; =
I double
checked time stamps, having write permission any problems with the
configuration file, bad install of the Cygwin packages etc, but no =
matter what,
fc-cache always fails on all possible font directories =
with:<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>&nbsp; failed to write cache<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>After googling around trying all the suggested =
solutions,
nothing was helping, and I ran strace and looked through the detailed =
system
calls. &nbsp;It turns out fc-cache tries to open cache files in read =
only mode.
&nbsp;&nbsp;&nbsp;Which means there is no way it can create cache files =
<span
style=3D'font-family:Wingdings'>L</span> <o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>So, I downloaded the source, compiled it up and =
added printf
statements throughout the call chain from scanDirs() downwards, and =
picked a
single directory to try and cache (the Type1 fonts directory for =
Cygwin).&nbsp;
This is what I see:<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>bash-3.2$ ./fc-cache.exe --force --really-force
/usr/share/fonts/Type1/<o:p></o:p></p>

<p class=3DMsoNormal>X: FcDirCacheValid =
/usr/share/fonts/Type1<o:p></o:p></p>

<p class=3DMsoNormal>X: FcDirCacheValidConfig calling through to
FcDirCacheProcess<o:p></o:p></p>

<p class=3DMsoNormal>X: FcDirCacheProcess =

<p class=3DMsoNormal>X: opening

<p class=3DMsoNormal>X: FcDirCacheProcess fd=3D-1<o:p></o:p></p>

<p class=3DMsoNormal>/usr/share/fonts/Type1: failed to write =
cache<o:p></o:p></p>

<p class=3DMsoNormal>bash-3.2$<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>The X: &#8230; lines are my printf statements I =
added to the code.
<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>I looked through the code by hand, from main(), to
scanDirs() and downwards, there is no possible way that I can see for =
fc-cache to
actually create caches on disk.&nbsp; &nbsp;The code that prints out the =
failed
to write cache message is just calling FcDirCacheValid(), but this =
function is
not used to create cache files (the error message of &#8220;write failed =
is
meaningless), only to open then and check that they are valid (hence =
strace
shows opening of cache files in read only mode with no creat =
flag..consistent
at least).<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>So from what I can tell, fc-cache is not the =
program to use
to populate the font caches the very first time.&nbsp; <o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>My question is, what program do I use?&nbsp; Can =
you update
your documentation to correctly point to the right program to use?&nbsp; =
<o:p></o:p></p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>This has been very frustrating to try and track =
down.&nbsp;
&nbsp;I guess when I have time next, I&#8217;ll try to understand the =
&#8220;init&#8221; call
tree that actually does call the functions which build cache files
(FcDirCacheScan), and maybe write a little program that specificalliy =
calls
those functions so I can get my caches populated, but I really =
don&#8217;t think I
should have to do that. &nbsp;&nbsp;fc-cache should work as its manpage =
says <span
