In particular, Apple decided to make the default filesystem on +Macs be case-insensitive some years ago, and this has exacerbated a +problem of people creating documents that use, say, an image under the +name 'foo.jpg', while the actual file is named 'foo.JPG' or 'Foo.jpg'. +It works on the Mac but if the document is transferred and run on a +standard case-sensitive Unix (file)system, the file can't be found, due +only to differences in case. + + This same problematic scenario has always existed on Windows, but for +whatever reason, it has become much more common since Apple also went to +a case-insensitive filesystem. Hence the move to change the Kpathsea +behavior now. + + The fallback case-insensitive search is omitted at compile-time on +Windows, where (for practical purposes) all file names are +case-insensitive at the kernel level, and so the normal search will +already have definitively matched or not. Therefore, search results in +unusual cases can be different on Windows and Unix--but this has always +been true. + + +File: kpathsea.info, Node: Casefolding examples, Prev: Casefolding rationale, Up: Casefolding search + +5.4.2 Casefolding examples +-------------------------- + +The casefolding implementation prefers exact matches to casefolded +matches within a given path element, so as to retain most compatibility. +Backward compatibility is not perfect, however, as a casefolded match +may be found in an earlier path element than an exact match was +previously found (see example #4 below). Still, preferring the match in +the earlier element seemed potentially less confusing than otherwise, +and is in fact consistent with past behavior on Windows. Since case +mismatches are rare to begin with, and name collisions with respect only +to case thus even more rare, the hope is that it will not cause +difficulties in practice. + + If it's desirable in a given situation to have the exact same search +behavior as previously, that can be accomplished by setting the +configuration variable 'texmf_casefold_search' to '0' (*note Path +sources::). + + Some examples to illustrate the new behavior follow. + + Example #1: suppose the file './foobar.tex' exists. Now, searching +for './FooBar.TeX' (or any other case variation) will succeed, returning +'./foobar.tex'--the name as stored on disk. In previous releases, or if +'texmf_casefold_search' is false, the search would fail. + + Example #2: suppose we are using a case-sensitive (file)system, and +the search path is '.:/somedir', and the files './foobar.tex' and +'/somedir/FooBar.TeX' both exist. Both now and previously, searching +for 'foobar.tex' returns './foobar.tex'. However, searching for +'FooBar.TeX' now returns './foobar.tex' instead of +'/somedir/FooBar.TeX'; this is the incompatibility mentioned above. +Also (as expected), searching for 'FOOBAR.TEX' (or whatever variation) +will now return './foobar.tex', whereas before it would fail. Searching +for all ('kpsewhich --all') 'foobar.tex' will return both matches. + + Example #3: same as example #2, but on a case-insensitive +(file)system: both now and previously, searching for 'FooBar.TeX' +returns './foobar.tex', since the system considers that a match. The +Kpathsea casefolding never comes into play. + + Example #4: if we have (on a case-sensitive system) both +'./foobar.tex' and './FOOBAR.TEX', searching with the exact case returns +that exact match, now and previously. Searching for 'FooBar.tex' will +now return one or the other (chosen arbitrarily), rather than failing. +Perhaps unexpectedly, searching for all 'foobar.tex' or 'FooBar.tex' +will also return only one or the other, not both (see more below). + + Example #5: the font file 'STIX-Regular.otf' is included in TeX Live +in the system directory 'texmf-dist/fonts/opentype/public/stix'. +Because Kpathsea never searches the disk in the big system directory, +the casefolding is not done, and a search for 'stix-regular.otf' will +fail (on case-sensitive systems), as it always has. + + The caveat about not searching the disk amounts to saying that +casefolding does not happen in the trees specified with '!!' (*note +ls-R::), that is, where only database ('ls-R') searching is done. In +TeX Live, that is the 'texmf-local' and 'texmf-dist' trees (also +'$TEXMFSYSCONFIG' and '$TEXMFSYSVAR', but those are rarely noticed). +The rationale for this is that in practice, case mangling happens with +user-created files, not with packages distributed as part of the TeX +system. + + One more caveat: the purpose of 'kpsewhich' is to exercise the path +searching in Kpathsea as it is actually done. Therefore, as shown +above, 'kpsewhich --all' will not return all matches regardless of case +within a given path element. If you want to find all matches in all +directories, 'find' is the best tool, although the setup takes a couple +steps: + + kpsewhich -show-path=tex >/tmp/texpath # search path specification + kpsewhich -expand-path="`cat /tmp/texpath`" >/tmp/texdirs # all dirs + tr ':' '\n' </tmp/texdirs >/tmp/texdirlist # colons to newlines + find `cat /tmp/texdirlist` -iname somefile.tex -print </tmp/texdirlist + + Sorry that it's annoyingly lengthy, but implementing this inside +Kpathsea would be a lot of error-prone trouble for something that is +only useful for debugging. If your 'find' does not support '-iname', +you can get GNU Find from <https://www.gnu.org/software/findutils>. + + The casefolding search is implemented in the source file +'kpathsea/pathsearch.c'. Two implementation points: + + * Kpathsea never tries to check if a given directory resides on a + case-insensitive filesystem, because there is no efficient and + portable way to do so. All it does is try to see if a potential + file name is a readable normal file (with, usually, the 'access' + system call). + + * Kpathsea does not do any case-insensitive matching of the + directories along the path.
