Fix signal handler safety issues (pcl-2tv) (#351)
- 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

Fix pcl-zqv.5.7: eliminate deadlock in pfs_get_both_locks (#339)
* Fix pcl-zqv.5.7: eliminate deadlock in pfs_get_both_locks

- Enforce consistent lock ordering: always acquire psql lock before file mutex
- Remove retry loop that could spin indefinitely
- Replace abort() with error return in pfs_lock_file timeout
- Add unit test verifying lock ordering prevents deadlock

Fixes GH #258

* Reorganize tests: smoke-tests, fault-inject, unit-tests

* Reorganize tests: smoke-tests, fault-inject, unit-tests

* Remove validation report

Fix debug build segfault: add strong overrides for psql_lock/unlock functions (#177)
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.

Fixes #138

Increase maintainability: namespace refactors for putil, pfs, and pfs sub-modules (#176)
* 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.
