replace fixed by exponential retries

replace fixed by exponential retries

Summary by CodeRabbit

• Improvements
  • Upload operations now retry automatically with progressively longer wait times when temporary failures occur.
  • Retries can continue for up to ten hours, improving resilience during extended service interruptions.
  • If retries are exhausted, the system reports which upload operation failed.

📝 Walkthrough

Walkthrough

push now retries author, journal, reviewer, and publication uploads with exponential backoff. Delays start at 120 seconds, cap at one hour, and stop after ten hours of cumulative retry time. Retry exhaustion produces operation-specific errors.

Changes

ZBMath upload retry policy

Layer / File(s)	Summary
Entity upload retry handling src/mardi_importer/zbmath/ZBMathSource.py	Author, journal, and reviewer operations use capped exponential backoff and a ten-hour cumulative retry budget instead of five fixed attempts.
Publication upload retry handling src/mardi_importer/zbmath/ZBMathSource.py	Publication processing tracks retry state, applies capped exponential delays, and stops after the ten-hour retry budget.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Suggested reviewers: eloiferrer

Merge Risk: 🔵 Low · up to ab24e

Repeated upload failures can keep an import retrying two minutes beyond the advertised ten-hour limit. Bound the final delay to the remaining budget before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Enforce the ten-hour retry budget in every upload path. Each block can sleep for 3,600 seconds after 32,520 seconds of prior retry delay. This produces 36,120 seconds of cumulative retry delay.

• src/mardi_importer/zbmath/ZBMathSource.py#L596-L596: Limit the author delay to max_retry_seconds - elapsed_retry_seconds, then exit when the budget is consumed.
• src/mardi_importer/zbmath/ZBMathSource.py#L646-L646: Apply the same remaining-budget limit to journal retries.
• src/mardi_importer/zbmath/ZBMathSource.py#L747-L747: Apply the same remaining-budget limit to reviewer retries.
• src/mardi_importer/zbmath/ZBMathSource.py#L863-L863: Apply the same remaining-budget limit to publication retries.
