Eelco Dolstra	9ee590e113	PosixSourceAccessor::cachedLstat(): Use absolute path ... Using the relative path can cause collisions between cache entries for PosixSourceAccessors with different roots.	2024-03-04 21:54:35 +01:00
Eelco Dolstra	930b9c8269	PosixSourceAccessor: Support roots that are not directories ... We have to support this for `fetchTree { type = "file" }` (and probably other types of trees that can have a non-directory at the root, like NARs).	2024-02-20 12:51:15 +01:00
John Ericson	4687beecef	Get rid of CanonPath::fromCwd ... As discussed in the last Nix team meeting (2024-02-95), this method doesn't belong because `CanonPath` is a virtual/ideal absolute path format, not used in file systems beyond the native OS format for which a "current working directory" is defined. Progress towards #9205	2024-02-08 11:01:41 -05:00
pennae	f9aee2f2c4	don't malloc/memset posix accessor buffer ... it's relatively small and fits on the stack nicely, and we don't need it initialized either.	2023-12-19 19:32:16 +01:00
Eelco Dolstra	57246c4c38	PosixSourceAccessor: Cache lstat() calls ... Since we're doing a lot of them in assertNoSymlinks().	2023-12-06 13:55:54 +01:00
Eelco Dolstra	83c067c0fa	PosixSourceAccessor: Don't follow any symlinks ... All path components must not be symlinks now (so the user needs to call `resolveSymlinks()` when needed).	2023-12-05 23:02:59 +01:00
John Ericson	ac89bb064a	Split up util.{hh,cc} ... All OS and IO operations should be moved out, leaving only some misc portable pure functions. This is useful to avoid copious CPP when doing things like Windows and Emscripten ports. Newly exposed functions to break cycles: - `restoreSignals` - `updateWindowSize`	2023-11-05 12:20:02 -05:00
Eelco Dolstra	2f5c1a27dc	LocalStoreAccessor: Reuse PosixSourceAccessor	2023-11-01 17:22:25 +01:00
Eelco Dolstra	cdb27c1519	SourceAccessor: Change the main interface from lstat() to maybeLstat()	2023-11-01 15:26:07 +01:00
Eelco Dolstra	34a42f0d0a	Move PosixSourceAccessor into its own file	2023-10-23 11:05:50 +02:00
