* nix-copy-closure: make sure that the shell doesn't do globbing of
...
`+' and `?' in filenames. This is very slow if /nix/store is very
large. (This is a quick hack - a cleaner solution would be to
bypass the shell entirely.)

* I forgot to catch SQLiteBusy in registerValidPaths(). So
...
registerValidPaths() now handles busy errors and registerValidPath()
is simply a wrapper around it.

* `nix-store --verify --check-contents': don't hold the global GC lock

while checking the contents, since this operation can take a very
long time to finish. Also, fill in missing narSize fields in the DB
while doing this.

* Retry a transaction if SQLite returns SQLITE_BUSY. This can happen
...
even with a very long busy timeout, because SQLITE_BUSY is also
returned to resolve deadlocks. This should get rid of random
"database is locked" errors. This is kind of hard to test though.
* Fix a horrible bug in deleteFromStore(): deletePathWrapped() should
be called after committing the transaction, not before, because the
commit might not succeed.

(namely, when there is a long region of 0s). On one 86 MiB
case, this cut patch generation time from 44m to 2m.

2010-11-29 09:26:05 +00:00

necessary because bsdiff has some pathological worst-case behaviour,

* When checking whether a patch is applicable, for efficiency, use
...
`nix-store -q --hash' to get the hash of the base path rather than
`nix-hash'. However, only do this for estimating the size of a
download, not for the actual substitution, because sometimes the
contents of store paths are modified (which they shouldn't, of
course).

* Store attribute sets as a vector instead of a map (i.e. a red-black
...
tree). This saves a lot of memory. The vector should be sorted so
that names can be looked up using binary search, but this is not the
case yet. (Surprisingly, looking up attributes using linear search
doesn't have a big impact on performance.)
Memory consumption for
