Doesn’t seem to have come through to the devel list (probably because
you aren’t subscribed), so I forward it.

Subject: Re: v2.19.47 on Mac x86
I run El Capitan 10.11.6:
address@hidden:~/Documents/LaTeX/PartitionsLilypond > uname -a
Darwin macbookprojm 15.6.0 Darwin Kernel Version 15.6.0: Mon Aug 29 20:21:34
PDT 2016; root:xnu-3248.60.11~1/RELEASE_X86_64 x86_64
and I get:
address@hidden:~ > sudo dtruss lilypond --version
I run El Capitan 10.11.6 and get the exact same output for “uname -a”.
I wanted to see what the difference was between v2.19.46 and v2.19.47, so I ran
them both on the following file:
bash-3.2$ cat 1note.ly
\version "2.19.46"
{ c4 }
<….>
I then ran dtruss -c on both versions to see what the difference in system
calls was.
The following table shows the number of system calls which have a Count > 100
for the v2.19.47 version and the corresponding count for the v2.19.46 version:
CALL COUNT LP46 COUNT LP47
… … …
getattrlist 112 128
stat 178 171
stat64 207 207
sigaltstack 222 228
sigprocmask 263 269
select_nocancel 320 323
lseek 57 123013
read_nocancel 341 125474
I then did a count of the number of lseeks on file descriptors <= 13 (at first
glance there are no file descriptors greater than 12:
lseek(0xfiledes v46 v47
lseek(0x0 1 23
lseek(0x1 1 1
lseek(0x2 1 1
lseek(0x3 2 2
lseek(0x4 0 0
lseek(0x5 0 0
lseek(0x6 2 2
lseek(0x7 35 35
lseek(0x8 8 122969
lseek(0x9 3 3
lseek(0xA 1 1
lseek(0xB 3 3
lseek(0xC 0 0
Hopefully, this information might be of use to someone trying to figure this
problem out.
The most salient questions would be: what is filedes 8 used for? And why is
this problem only occurring on Macs?

I did a dtrace on 2.19.47, using the default introductionary song that Lilypond
uses as a starting sample (when starting the Lilypond app)
#!/usr/sbin/dtrace -s
syscall::lseek:entry /execname == "lilypond"/ { printf("lseek for %s ",
execname); }
syscall::open*:entry /execname == "lilypond"/ { printf("%s %s", execname,
copyinstr(arg0)); }
Searching within the created log-file of all dtrace hits for "open", so that
only the open* entries are found shows that apparently the lseek-explosion occurs while
lilypond is scanning the Mac OS X Fonts (this was not the first run of 2.19.47, so the
initial font-scanning of the first run can not be blamed (unless the changes from 2.19.46
to 2.19.47 broke the font-caching system for Mac OS X of course)):
CC-ing lilypond-devel as this may provide useful information for them too
