simple-file-poller 0.0.11

Simple Python 3 library for file polling.

Simple Python framework for performing file polling.

It polls for files in the specified input directory and moves them to the output directory. Methods for checking the files (e.g., whether an image is valid) and processing them can be supplied to the poller instance. Optionally, the input files can be deleted rather than moved.

Changelog

0.0.11 (2024-09-13)

• using shutil.move instead of os.rename to work across file-system boundaries

0.0.10 (2021-03-18)

• added the output_num_files boolean property to the Poller class, which extends the logging output by outputting a x/y string as well (x=current file index, y=total number of files in a batch)

0.0.9 (2021-01-05)

• the Poller.logging property no longer returns the check_file method

0.0.8 (2020-12-11)

• fixed high CPU usage (ie constant polling) when using unlimited files to list (max_files=0)

• poll_wait and watchdog_check_interval are now float instead of int to allow for sub-second poll waits

• internal delays when poller is busy have been dropped from 1s to 0.1s

0.0.7 (2020-12-10)

• keyboard_interrupt method is now public

0.0.6 (2020-12-10)

• fixed race condition between watchdog reacting to new files and watchdog checking for files at specific intervals

• logging now distinguishes between DEBUG/INFO/ERROR levels

• keyboard interrupts via CTRL+C are now handled correctly

• in watchdog mode, an initial scan of the input directory is now performed, in case files were already present

0.0.5 (2020-12-10)

• added params object to allow attaching of arbitrary parameters to be used by the check_file and process_file methods; this avoids accidentally overriding Poller attributes that were introduced in later versions.

0.0.4 (2020-12-10)

• added support for using watchdog for reacting to file creation events, speeding up polling

0.0.3 (2020-12-04)

• poll method now skips directories, which could be listed if no extensions are supplied to restrict the polling.

0.0.2 (2020-12-03)

• added other_input_files glob list and delete_other_input_files to manage additional files that may reside in the input directory along side the actual files that are being processed.

0.0.1 (2020-12-02)

• initial release
