- Use fuse_loop_mt_312 for FUSE 3.12+, fuse_loop_mt_31 for 3.0-3.11
- Conditionally add fuse_file_info param to getattr/chmod/chown/utimens
- Replace fuse_session_mount/unmount with fuse_mount/unmount
- Tested with FUSE 3.18 on Debian forky
- Remove hardcoded FUSE_USE_VERSION defines from source files
- Add FORCE_FUSE=2 or FORCE_FUSE=3 Makefile option to override detection
- Fix FUSE 2 channel tracking (psync_fuse_channel variable)
- Properly store and use channel in mount/unmount for FUSE 2
Usage:
make # Auto-detect (prefers FUSE 3)
make FORCE_FUSE=2 # Force FUSE 2 build
make FORCE_FUSE=3 # Force FUSE 3 build
Verified both FUSE 2 and FUSE 3 builds work correctly.
FUSE 3 init handler requires struct fuse_config* parameter.
This parameter provides access to high-level API configuration
options that can be modified during initialization.
Without this parameter, the init handler signature is incompatible
with FUSE 3, causing filesystem operations to fail.
- nonempty: Removed in FUSE 3.0, mounting on non-empty directories is now default behavior
- hard_remove: High-level API option not available in FUSE 3, immediate unlink is standard
These options are no longer recognized by FUSE 3 and cause mount errors.
- Update FUSE_USE_VERSION from 26 to 30
- Replace fuse_mount/fuse_unmount with fuse_session_mount/fuse_session_unmount
- Update fuse_new() to take args first, remove channel parameter
- Add flags parameter to readdir handler (enum fuse_readdir_flags)
- Add flags parameter to rename handler (for renameat2 support)
- Update filler function calls to include FUSE_FILL_DIR_PLUS flag
- Merge ftruncate into truncate handler (FUSE 3 combines them)
- Update fuse_loop_mt to fuse_loop_mt_31 with loop config
- Link against libfuse3 instead of libfuse
- Remove fuse_chan usage (deprecated in FUSE 3)

- Implements flag-based deferred signal handling pattern
* Integrate psignal into main loop and remove conflicting handlers
- Added extern "C" linkage to psignal.h for C++ compatibility
- Integrated psignal_check_pending() into pclsync_lib.cpp main loop
- Integrated psignal_check_pending() into ptimer.c timer loop
- Removed conflicting signal handlers from pfs.c
* Migrate psync_set_signal to psignal module
- Added psignal_set_custom_handler() to psignal.h and psignal.c
- Replaced psync_set_signal() calls in pfs.c with psignal_set_custom_handler()

* Fix pcl-3la.1: saturating addition for bytestou in pstatus_upload_recalc
Replace unchecked uint64_t summation in pstatus_upload_recalc() with
overflow-safe saturating addition. Before adding each file's size,
check if the result would wrap around UINT64_MAX; if so, saturate to
UINT64_MAX instead of silently wrapping.
Ref GH #293.
* Fix pcl-3la.2: remove spurious fuse_loop_mt while-loop and exit(0)
fuse_loop_mt() already loops internally; wrapping it in an additional
while loop caused repeated re-entry after normal exit. Also removes
the exit(0) call in the shutdown path so fuse_destroy() and other
cleanup run properly on shutdown.

- Use sig_atomic_t flag instead of calling unsafe functions in signal handlers
- Remove pdbg_logf() and exit() calls from psync_signal_handler
- Check shutdown_requested flag in main loops
- Export flag for cross-module access

The weak/strong symbol approach requires that psql.c undefs the debug
macros to define function implementations. This means functions in psql.c
call psql_lock()/psql_unlock() as functions, not macros.
In debug builds, these must be strong overrides that call the _do_
variants to properly maintain lockctr/rdlockctr. Without these overrides,
the weak stubs are used which don't update counters, causing assertion
failures in psql_unlock().
Added strong overrides in psql_debug.c for:
- psql_lock() -> psql_do_lock(__FILE__, __LINE__)
- psql_rdlock() -> psql_do_rdlock(__FILE__, __LINE__)
- psql_statement() (calls psql_do_lock directly)
Also made psql_statement, psql_start, and all query/prepare functions
weak in psql.c to allow debug overrides.

* Fix#103: Refactor putil to use putil_ namespace and enforce encapsulation
All public functions in putil now use the putil_ prefix (e.g., putil_strdup,
putil_strcat, putil_time_format, putil_base64_encode, etc.). Internal
variables (normalize_table, base64_reverse_table) and the constructor remain
static. Updated all 34 call-site files across pclsync accordingly.

* Fix#96: Refactor pfs to use pfs_ namespace and enforce encapsulation
All public functions in the pfs module renamed from psync_fs_ to pfs_
(e.g., pfs_update_openfile, pfs_refresh, pfs_start, pfs_stop, etc.).
Extern vars psync_fake_prefix/psync_fake_prefix_len renamed to
pfs_fake_prefix/pfs_fake_prefix_len. Functions only used within pfs.c
(pfs_update_openfile_fileid_locked, pfs_chown) made static. Updated all
call sites across 17 files including pclsync_lib.cpp.

* Refactor pfsxattr to use pfs_xattr_ namespace
All psync_fs_ prefixed functions in the pfsxattr module renamed to
pfs_xattr_ (e.g., pfs_xattr_set, pfs_xattr_get, pfs_xattr_list,
pfs_xattr_remove, pfs_xattr_file_deleted, pfs_xattr_task_to_file, etc.).
Local macro psync_fs_set_thread_name renamed to pfs_xattr_set_thread_name.
Internal static helpers (delete_object_id, update_object_id,
xattr_get_object_id_locked) remain static and unchanged.
Updated all call sites in pfs.c, pfsupload.c, and pdiff.c.

* Rename pfs_xattr_ namespace to pfs_xatr_
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Refactor pfs sub-modules to use namespaced function prefixes
- pfscrypto_* → pfs_crpt_*
- psync_fsstatic_* → pfs_stat_*
- psync_fsupload_* → pfs_upld_*
- psync_fstask_* → pfs_task_* (functions only; typedefs unchanged)
- psync_fsfolder_*/psync_fsfolderid_*/psync_fsfolderflags_*/
get_decname_for_folder/psync_get_folderid → pfs_fldr_*
Type names, macro constants, and typedef aliases are unchanged.
Updated all call sites across 17 files.
