[Ids-devel] File Date Info Cache

[Robin * S. <pre...@pa...>]

Hello,

IDS had severe performance problems for me.  I have directories of
500-2000 photos now that big compact flash cards are cheap.

Up to 9 seconds to load a page, down to less than 2 seconds with this
mod.  The idea is to cache the time info in album-data directory.

basically I changed

fillDateHash()

To find out if the data is already in %mtime, if it is not, then read
the cache, if it is still not there, check the file via the old means.

After rendering the page, then it writes all the data in %mtime out to
album-data/ALBUMNAME/time-cache.txt

The problem was that before this change, the date info was re-calculated
for every page view for all files in an album.  This made large albums
very very slow to view.

I added 3 new functions to do this.

getMtimeCacheName() given a file return the name of its cache.
readMtimeCache() fill mtime from a file.
writeMtimeCache() given the hash write it out to a file(s)
