* util.datamanager: Pad list writes to avoid crossing block boundariesKim Alvefur2023-06-071-0/+7
| | | | | | | | | | | By padding items so that they do not cross block boundaries, it becomes eaiser to delete whole blocks with fallocate() without cutting items in half, improving efficiency of such operations. Since list stores are used for message archives, where the most common deletion operation would be of the oldest entires, at the top of the file. With this, all blocks that contain items to be removed could be deleted without needing to read, delete and write out the whole file.
* util.datamanager: Efficiently remove whole blocks to shift listsKim Alvefur2023-07-121-0/+40
| | | | | Using the new pposix.remove_blocks() it should be very performant to delete whole sections of a file, given a supporting file system.
* util.datamanager: Add way to efficiently remove first items in a listKim Alvefur2023-07-121-0/+92
| | | | | Copying data without parsing it should be more performant than parsing it serializing back.
* util.datamanager: Fix indexing first item if not at the very startKim Alvefur2023-07-101-2/+2
| | | | | | | | If the first item does not start at position 0 then the index function produces a phantom first entry covering position zero until where the real first item starts. When using the index, this would make it either appear as the first item was missing or cause an off-by-one issue with remaining items.
* util.datamanager: Reduce log level of left over debug messages to debug ↵Kim Alvefur2023-07-121-2/+2
| | | | | | (thanks Trung) These were mostly 'warn' to make them stand out from the debug noise

* util.datamanager: Halve size of list indexKim Alvefur2021-05-141-11/+15
| | | | | Instead of storing (start, length) tuples, store the offset to the end of items and derive length using the previous entry.
* util.datamanager: Add O(1) list indexing with on-disk indexKim Alvefur2021-05-111-0/+191
| | | | | | | | | | | | Index file contains offsets and lengths of each item() which allows seeking directly to each item and reading it without parsing the entire file. Also allows tricks like binary search, assuming items have some defined order. We take advantage of the 1-based indexing in tables to store a magic header in the 0 position, so that table index 1 ends up at file index 1.

* util.datamanager: Support iterating over any file extensionKim Alvefur2021-02-071-4/+3
| | | | | | | | The 'typ' argument to all other functions is the actual file extension, but not here for some reason. May need this for iterating over the .bin files created by mod_http_file_share in the future.
* util.datamanager: Fix not passing variables as format string to logger ↵Kim Alvefur2021-01-161-1/+1
| | | | | | | (thanks semgrep) Passing error messages as format string could lead to errors, although not a problem anymore since util.format sanitizes this.

| | | | | | | | | | | | | | | | | | The 'store' path componend used to be unescaped until 756a2a00e7e7 added escaping to address issues with characters like '/' used in PEP, but with a special case for '_' which was already in common use in 'store' path components. Missed adding this escaping here.
